SUBSTANCE: sand and grit catcher comprises a main receiving cylindrical container 1 installed within an additional container 2 of a larger volume. The main receiving container 1 houses a hollow cylinder 10, coupled to the supply water conduit 12. The cylinder 10 is divided by a horizontal partition wall 13 into two cavities 15 and 16. The horizontal partition wall 13 has a hole in the middle part. Water-discharge windows 20 are located in the walls of the cylinder 10 above the partition wall 13. Water-discharge orifices 6 are located in the walls of the sloping bottom 5 of the main container 1 relative to each other.

The invention relates to hydraulic engineering, namely, devices for purification of water from the sediment, and is intended to prevent sediment and suspended solids fractions greater than 0.2 mm, in pipelines with pumping water for irrigation and avancuara pumping stations.
A device for clarification of water, comprising a housing with a discharge channel, a spiral chamber located inside the housing and is made in the form of an overflow wall, the inlet channel connected to the inlet to the spiral chamber, and a wash pipe connected to promiseme the hole in the bottom of the spiral chamber, while vodoprovidna wall defined by coil spiral of Archimedes in the range of the rotation angle of the radius vector, and washing the hole is located at the pole of this spiral (USSR author's certificate No. 1330254, CL E02B 8/02, 1987).
The disadvantage of this device is due to its complex structure, including spillway wall, defined by the spiral of Archimedes within a angle, and complexity of its hydraulic calculation. Low reliability is that suspended sediment fractions, pereraspredelyaet in plan, partly in suspension can flow through the overflow wall into the housing and then to the consumer. This primarily requires the constant overflow of water, however, in the process of construction, is produced in the runs frequent change of costs in the supply channel. In the case of saturation flow in large quantities harvested and suspended sediment, washing hole is unable to cope with their washing, and there is a partial blockage across the width of the camera. This results in higher filling in the annular chamber, and the load may be accessed through the overflow wall to the consumer, i.e. the height of the overflow wall is not designed for such hydraulic mode of its operation, respectively, of a hydraulic structure in the cell changes. In this case, smaller sediment will begin to flow in the discharge pipe to the consumer. Thus, the known construction is not possible to completely protect the clean water part of the suspended load. The task in the known device can be solved only in one technological cycle, protection from sediment under certain specified design flow.
Closest to the proposed assignment, the technical essence and the achieved result is a clarifier, which is to improve the reliability equipped with a float valve installed at the end of the discharge tube positioned in facing the outlet nozzle section body (USSR author's certificate No. 1350242, CL E028/02, 1987).
A disadvantage of the known device is periodic supply of water to the consumer at the discharge nozzle, which is interrupted at the time of washing on the of STOLICA through the use of ascending and descending branches of the siphon. As a result, the piping with clean water creates air pockets that reduce the efficiency of the known device and thereby interfere with water supply. In addition, there is a blockage of the outlet of the ascending branch of the siphon accumulated sediment in the conical part of the tank near a window and natural mudding them, which may prevent the inclusion in the work of the siphon (first) and lead to failure of the suction effort of the siphon to lift the weight of the entire height of the ascending branch of the siphon, i.e., the height from the inlet of the siphon, up to the hood.
Also known, for example, hydrocyclones and packageview copyright certificates of the USSR: №№184187, 367895, 544473, 816558, 823647, 882942, 886998, 106552, 1392188, 1456234, 1546547.
However, the known devices are complicated by numerous elements, not practical to manufacture, which does not allow for reliable continuous operation of the devices during their operation.
The purpose of the invention is to improve efficiency by facilitating flushing of bottom and suspended sediments in the discharge header.
This objective is achieved in that packagefile, including serving for collecting sediment receiving tank has a cylindrical shape having an inclined bottom and is in communication with the supply conduit and sbresny manifold, inlet conduit f is Yong extinguishing device in the form of a hollow cylinder with the water outlet Windows divided into two cavities by a horizontal floor with a hole in the middle part, mounted below the water outlet boxes, pyramid-shaped divider is aligned with the hole in the wall above the sloping bottom, which holds the outlet of the bottom hole and forms with the wall of the main cylindrical vessel in a narrow part of her washing the window, communicated with the cavity of the collector by means of additional capacity, the volume of which is greater than the volume of the main tank, with walls sloping bottom of the main vessel relative to each other made the water outlet holes are nanocatalysis elements in the form of paddles with possibility of vertical travel in the direction of the hollow cylinder from the main cavity capacity while the bottom of the primary and secondary tank is tilted at different angles to the horizontal axis of the device, mounted at the base of the Foundation. In addition, in order to reduce deformation of the device in a changing energy parameters of the falling stream of water, it provided the Foundation on which you installed additional capacity, with the rows of holes in the walls of the cylinder are located closer to the hole in the wall, have a smaller diameter than the hole in the partition.
This interrelation and interdependence of major E. the elements of packageview will allow high-speed stream of water, enriched sediments into, first, to the base, passing through an air layer, expand and lose some kinetic energy. Sand, gravel and part of the suspended sediment is routed through the hole in the middle part of the septum and share pyramidal divider before proryvnym bottom of the main tank. In the process, in the upper part of the vessel is set afflux of water with a certain air layer, the height of which is assigned depending on the kinetic characteristics of the flow (stream) of water, adjustable nanocatalysis movable elements, at the same time, the design of the narrow part of the main tank effectively uses the compression area of the stream with its hydraulic flow structure. While in the extended cavity of additional capacity drawn and suspended sediment continue to act on the inclined bottom and through the water outlet hole, overlapping nanocatalysis elements in the form of paddles, water under pressure jets washes continuously deposited sediment with tapered walls of the bottom of the stop ring drum, in the direction of the flushing pipe (channel). When raising or lowering the gates they open partially or fully water outlet hole in the sloping walls of the bottom of the main tank. Thus, the height of backwater water in it for education in the upper part of who the ear layer and wash sediment into the narrow part of the latter is regulated by the shutter. In this regard, is the full amount of the narrowest part of the additional capacity for removal of her drawn and suspended sediments, even with the decline in water flow from the inlet conduit, through the installation of a pressure mode in the main vessel, i.e., depending on the kinetic characteristics of the flow and allocation of the air layer in the upper part of the vessel. The proposed facility shall provide the necessary deformation of the thread height of vertical tanks and promotes the flushing of sediment down the inclined bottom with a slope of 45 to 60° in the main tank, where the stream loses a major part of the kinetic energy, and the additional capacity with tilt bottom and angle of not less than 30° shall take account of the receipt of the jet through the water outlet holes in the walls of the main tank, do not create a barrier (shielding) to move them up. In addition, the quality of the treated water in the area between the walls of the primary and secondary extended tanks when the water enters the top of the discharge pipe (channel) clarified water. Compared with the prototype of the proposed device operates in a mode of continuous supply of clarified water to the consumer, and reset it to flush sediment reaches the minimum cost due to their active flushing in the narrow part of the additional capacity, respectively, and the main tank.
Different angles of the inclined walls of the container and the connection with the elements of the structure improved hydraulic characteristics of the falling water stream sediment.
Thus, the splitting of the high-speed stream is already in the upper part of the hollow cylinder on a private jet and hit the lower part with two tiers (tiers may be more depending on outlet boxes in hollow cylinder) allows to increase the reliability of structures by expanding the range of effective flushing of bottom and suspended sediments. Hydrodynamic and pulsating load is transmitted through the additional capacity is larger at the base, in which it was placed.
The volume of all tanks and screening area they are different, accordingly, the rate of water movement in a vertical tanks may be appointed by the calculations, as the inclination of the walls of the bottom (tapered) portion of the deposition of sediment and wash it in the discharge conduit. For example, the amount of additional capacity (camera) can increase by up to 70% compared with the volume of the main tank, running at full recycling and supply of clarified water to the consumer. Loss of gravel and sand on the bottom of the additional capacity in the course of their active flushing using water from the water outlet holes of the main tank, simplifies the construction, R is the result that reduced the cost of its operation.
Such performance design packageview, according to the author, was not known and meets the criterion of "Significant differences".
The drawing schematically depicts packagefile, General view.
Packagefile includes a main receiving tank 1 has a cylindrical shape, is installed in the additional capacity of 2 larger, mounted on the inclined bottom 3 koronadalenos cowling 4. In the walls of the sloping bottom 5 made the water outlet hole 6, attached to the butterfly valve 7 to the actuator 8, aimed at moving towards the inclined bottom 9 at an angle. The gates 7 are, respectively, flat on the inner side of the container 1 and is made in the form nanocoating elements, opposite the inclined bottom 9 extinguishing device in the form of a hollow cylinder 10, coaxially mounted with the lower end 11 of the inlet conduit 12. In the cylinder 10 can be tted with the partition wall 13 with an opening 14 in the middle part divides it into two cavities 15 and 16, one of which is connected with the inlet of the inlet conduit 12 (cavity 15), and the other (the cavity 16) connected to the output 17 of the hollow cylinder 10 and the cylinder is provided with a pyramidal divider 18 in the cavity above the inclined bottom 9, coaxially located hole 14 of the partition wall 13, respectively, promiseme conical hole 19 in the narrow part of the vessel 1. Above is ergorace 13 in the walls of hollow cylinder 10 opposite each other holds the outlet box 20 with the grid 21 made with G-shaped cross-section with the outer side of the cylinder 10 in the direction of the main tank 1. Outlet ports 20 on the inner side of the cylinder 10 is limited by the rigid ring 22 with a fixed nozzles 23 in boxes of 20 (the window can be closed by a shutter in the form of plates, not shown). In addition, in the center for the vessel 2 is made of wash pipe 24 and the container 2 has reported her outlet pipe 25 of clean water in the upper part of the vessel wall 2. The upper part of the tank 1, in the process, establishes certain water-air layer 26, the height of which is assigned depending on the kinetic characteristics of the jet, i.e. the higher the speed of the falling stream of water, the greater the height of the air layer is required for damping, and adjustable prop the tank 1, respectively, the gates 7 drive 8 nanocoating elements aimed at moving towards the inclined bottom 9 of the hollow cylinder 10. Between the walls of the main container 1 and the additional container 2 has a cylindrical shape formed area of calm water conditions 27. The dimensions of the cylinder diameters and capacities are different. Additional capacity of 2 made in the form of a cone, formed down the narrow part, and installed on the Foundation 28.
Packagefile works as follows : the m
Water together with drawn and suspended sediments from the inlet conduit 12 enters the hollow cylinder 10 role extinguishing device at the first stage of movement of the stream of water, where the high-speed jet, reflected from the installed partition 4, extends in the direction of the window 20 with the pipes 23 and meshes 21, loses some kinetic energy. The water rises around the circular section of the main tank 1 and the inclined bottom 5 and passes through the water outlet hole 6, the overlapped nanocatalysis elements in the form of a butterfly valve 7 into separate streams, and falls onto the inclined bottom 3 with koronadalenos cowling 4. In the cavity 26 of the tank 1 there is intense stirring, turbulization, aeration, collision flows and interaction with a horizontal partition 14. Released the air from the water accumulates in the cavity 26 where the pressure it produces a smoothing of the ripple of the water and the presence of nozzles 23 reduces noise between the walls of the container 1 and of the cylinder 10 due to the compression of air entering with the water flow. Opposite walls inclined bottom 9, the installation nanocoating elements in the form of paddles 7 provides regulation and damming of water column between the walls of the container 1 and of the cylinder 10. In addition, adjustment of backwater water height in the tank 1 creates an increase or decrease in the entrance area Econ. The influence of this phenomenon in the upper cavity 26 of the tank 1, the water calm under pressure flows around the circular section at the bottom 3 and the shell 4, and the use of nanocoating elements 7, washes fine and coarse sediment in the direction of the wash pipe 24 with costs not exceeding the estimated discharge of about 5-10% of the total flow coming from the inlet conduit 12. Weight the weight of the water column in the additional vessel 2 and the retention time of her from the forces of pressure is provided in the base 28. When this backwater valves 7 concentrates sediment to promiseme hole 19, the angle of the bottom is narrow portion is equal to 45-60° to the horizon, and complete cleaning of the bottom 3 and the shell 4 of the container 2 in a larger volume of water to flush sediment after receiving them from the main tank 1 (degrees) allowed the reduction of the narrow part of the cone with a slope of not less than 30° to the horizon.
The estimated flow rate of take based on the lowest speed deposition of those particles on detention which is calculated packagefile. Thus, the efficiency of packageview will depend on the design of the extinguishing devices and flushing of sediment by varying the pressure between the cylinder wall and the main receiving tank, which provides a speed output ovet the military water in the absence of resuspension of sediment, dropped in the tank with a large volume of water. In connection relationships of the elements of the device, process calculation is given the original data, which can be attributed estimated depth (the distance between the walls) structures and hydraulic particle size of the impurities of sediment detention which it was intended.
Thus, the compulsory regulation of the water column in the tank 1 gates 7 in the process increases the compression ratio of the flow of water between the sloped bottom of the tank 1 and a sloped bottom of the cylinder 7, with various changes of water consumption of saturated various fractions of the sediment, may be increased effect of energy dissipation and efficiency flushing of bottom and suspended sediments with less sbresny and proryvnym water flow. Inclined annular shell 4 larger volume of the vessel 2 with a conical bottom simultaneously for the entire section is filled with water jets coming under pressure from the tank 1, and the treated water through the side wall of the container 2 in the upper part, in the quiet zone status 27 flows into the discharge pipe 25, purified from the sediment to the consumer. The end of the pipe 25 is located in the upper part of the vessel 2, and speed around the living section in the beginning of the outlet pipe 25 have the same values. In turn, the installation of the main tank 1 and the cylinder 10 to anitelea capacity 2, makes the construction much more economical, because, on the basis of the interrelation and interdependence of packageview, by successive steps, improves hydrodynamic load capacity is larger and there is no need to make it deep.

FIELD: water construction purification.
SUBSTANCE: invention relates to hydromechanisation namely to technology of purification and restoration of biological ponds of purification plants. Method of purification and restoration of biological ponds of purification plants includes intake of silt sediments with suction dredge from the bottom of multi-sectional pond and their transportation to sedimentation tanks. Pond is divided into two working areas of treatment, the latter is connected by means of additional input collector with sewage-water supplying canal in direction of sewage water flow motion, the former is blanked off, and construction of ground dam in area of purification is carried out as protective means. After that step-by-step purification of area is performed, for this purpose trench in silt sediments layer is sucked off by suction dredge, after that clarified water is pumped out and discharged into diversion canal. Silt sediments are collected in flowing state and transported either to silt sites or to sedimentation tanks. After that compressed silt sediments are dried by means of active ventilation and removed layer by layer as upper layer dries. After complete removal of silt sediments, base, bed of purified pond section, is restored, and said procedures are step-by-step repeated in successive purification of all sections of first area. Before purification of second working area round dam is erected again in last section of first working area of treatment, separating it from second working area, which is blanked off. First working area is joined to additional output collector with branch duct and opened, after which purification and restoration of sections of second working area are carried out. After finishing purification works ground dam, which was re-erected between two working areas, additional input and output collectors are removed, and second working area of pond is opened for functioning.
EFFECT: ensuring possibility of functioning of purification plants biological ponds without stopping them for purification.
