In installations for the production of drinking water production plants, irrigation systems and installations for electricity production uses large amounts of water for their operation. To collect water used sinks with trash sieve in different reservoirs. As shown in figa, one common type of receiving water 10 with trash sieve has a T-shaped configuration with two screens 12A-B at opposite ends of the Central housing 14. The outlet 16 is connected to the Central housing 14 for connection with components of the system of the recipient with trash sieve.

The ice machine 10 with trash sieve should be arranged in such a way as to preserve the aquatic flora and fauna and to prevent the accumulation of sediment along the Sith 12A-B of the receiving water. For this purpose, the flow rate through sieves must be maintained below the maximum peak level, which may be approximately 0.5 feet per second. One way to reduce the flow resistance and speed control flow evenly over the surfaces of the screens is to use modifiers input flow sieve. For example, sieves from Johnson Screens - assignee of the present application improves the uniformity of flow using flow modifiers described in U.S. patent No. 6051131 and 6712959, which included sudava its entirety as reference material.

When using the original drainage sinks 10 with trash sieve shall be placed with the presence of the interval that is not less than the minimum of the surrounding frame. As shown in figv, standard water intake 10 requires that the above interval above and below the water intake 10 with trash sieve was at least half the diameter of the receiving water. For example, the ice machine 10 with trash sieve having a diameter of 24 inches for the normal functioning requires a gap of 12 inches above and below the water intake 10. Thus, the ice machine 10 with trash sieve with a diameter of 24 inches can be installed in the water to complete a minimum depth of 48 inches (4 feet).

Available sources of raw water for water intake systems are becoming smaller. For applications in shallow water was used flat screens, plugs for speed control or robovie stands for sampling of raw water. These traditional approaches provide a flat location on the bottom of the source water. However, the flat shape of the Sith these types can cause problems of deflection and strength, when they are exposed to flow and sediment. In addition, SITA these types can cause difficulty in maintaining cleanliness from the sediment. Finally, square the sky sieves are uneven flow distribution across the area of the surfaces of the Sith, that can cause problems during operation. The object of the present invention is directed to overcoming or at least reducing the effects of one or more of the above problems.

The receiving device with trash sieve has a base which is located at the bottom of the water source. The base may be a concrete slab or platform resting on the bottom and having a top surface. The recipient with trash sieve is located on the base and forms a half cylinder. Anchors can attach the edges of the receiving water with trash sieve to the upper surface of the base. In the river, or body of water with strong currents, the base preferably has a barrier that is located on one end in the flow of raw water, to discard the sediment and silt from the water intake with trash sieve.

The recipient with trash sieve has a body with first and second screens at the ends. Each of the sieves forms a half cylinder on the basis of and forms the inner space. The internal space communicated with the internal space of the housing so that the source water entering the sieve is held in the housing and exits through a common outlet.

Each of the first and second sieve has a side wall of the sieve, a closed distal end and open proximally the end. Open proximal end attached to the body, while the closed distal ends of the end wall, which form a half circle. Preferably, the receiving water with trash sieve has an intermediate wall located between the inner space of the shell and the inner spaces of the Sith. In each of the transition wall is located at least one flow modifier. The flow modifier has one open end which is connected with the inner space of the sieve, and has another open end of which is connected with the inner space of the housing. The flow modifier may have two or more modifiers of the thread is inserted into each other, and these flow modifiers in conjunction with the base also forms a half cylinder.

The recipient with trash sieve may also have a reservoir located in the sieves, for receiving the supplied air used to clean screens from the sediment. The design of the screens may include ribs along the length of the sieve, and may have a wire that is located across the ribs. In General, the semi-cylindrical receiving water with trash sieve mounted on the upper surface of the base, may have all the signs of normal water intake with trash sieve, but to have a very low profile for use in more IU is such waters.

The above summary of the invention does not provide for the coverage of each potential option exercise or each object of the present invention.

System 50 of the receiving water with trash sieve, shown in figure 2, has two water intakes 100 with trash sieve, although can be used more or less sit. Each recipient with 100 trash sieve is located on a base or platform 60, which is located in the flow of a water source, such as a river. On figa and 3B shows the top and side views of the platform 60. The platform 60 may be a concrete slab, etc. and can build on the bottom of the water source. As shown in figv, the platform 60, preferably, is at least 3-4 inches above the bottom of the water source.

In a river or other source, where there is for the front end of each platform 60 is shaped barrier 62 for dividing the flow of water before the water intake 100 with trash sieve. Profiled barrier 62 preferably has an inclined edge and divides the flow of water, sediment and silt. In addition, as shown in figv, profiled barrier 62, preferably, is approximately the height of the recipient 100 with trash sieve, based on the platform 60. The barrier 62 may be performed separately from the platform 60, or may be formed as a single unit with it. Alternatively, the barrier 62, the recipient 100 with trash sieve may be provided with a profiled end.

the AK is shown in figa, the recipient 100 with trash sieve can have a T-shaped configuration with first and second sections 110A-B sieves connected at opposite ends of the Central housing 120. The end wall 115A-B close the ends of the sections 110A-B bolt and a Central discharge outlet 130 passes from the Central housing 120. Alternatively, the recipient 100 with trash sieve can have a single partition 110 sieves connected to the housing 120 of the outlet 130, while the other end of the housing 120 is closed and has a second section 110 of the sieve.

As shown in figs, the recipient 100 with trash sieve forms a half cylinder on the upper surface of the platform 60. In General, the recipient 100 with trash sieve has a semi-cylindrical sieve for screening sections 110A-B, along with the end walls 115A-B in the form of a half circle. The housing 120 may have a semi-cylindrical side wall, although it can be used in another configuration. All of these components (110, 115, 120) may be attached to each other using well-known technical means. In one embodiment, the water receiver 100 with trash sieve has a flat bottom component that is attached to the edges of these mutually connected components (110, 115, 120). This flat bottom may lie on the upper surface of the platform 60, while the anchor bolts 6, etc. attach a water body 100 with trash sieve to the platform 60.

Alternatively, the ice machine 100 may have a generally flat bottom component that is attached to the edges of the connected components (110, 115, 120). Instead, the free edge are mutually connected enclosures 120, screening sections 110A-B and end walls 115A-B can be attached directly to the platform 60 with the use of anchor bolts 64 and the like, for Example, the platform 60 may have a width and length that is slightly larger than the receiving water 100 with trash sieve, about 3 inches or so. The platform 60 may have holes formed around its perimeter for sealing concrete anchor bolts 64, which keep the water intake 100 with trash sieve on the platform 60.

In another embodiment, the water receiver 100 with trash sieve may be cylindrical (or at least partially cylindrical recipient with trash sieve, partially embedded in the material of the platform 60. In this embodiment, the fully or partially cylindrical recipient 100 with trash sieve can be embedded in the concrete slab of the platform when the platform 60 using known techniques.

When assembling the recipient 100 with trash sieve is the set premounted on the platform 60 on the earth, and both 60/100 can be sunk to the bottom of the water source. In an alternative embodiment, the recipient 100 with trash sieve and the platform 60 may be formed separately. The platform 60 may be placed at the bottom of the water source, and water intake 100 with trash sieve can be attached to the upper surface of the platform 60 with anchors 64. These and other forms of construction can be used for system 50 of the receiving water with trash sieve.

As shown in figure 2, the outlet 130 of the recipient 100 with trash sieve are connected by a pipe 52 with the equipment (not shown), configured to use water usage. Preferably, the water inlet 100 and the platform 60 are displaced relative to each other so that they were not in a cocurrent flow relative to each other. The recipient 100 with trash sieve mounted on the bottom of the water source, reduces the depth required to fence the same thread as in the case of regular water intake. For example, the recipient 100 with trash sieve may have a diameter of 24 inches (radius 12 inches). This requires a period of 12 inches above the water intake 100 with trash sieve in order to work properly.

As shown in figa, for example, a water body 100 with trash sieve according to the present and the attainment of diameter d 24 inches can be operated at full minimum working depth D1, component of just about 20 inches. This provides advantages over known systems through the use of a 24-inch T-shaped sieve 10 of the prior art, shown for comparison in figv. Such well-known T-shaped screen 10 of the prior art requires a depth D2 of water 48 inches.

As shown in figa-3B, each of the screening sections 110A-B forms a set of grooves for water input screen sections 110A-B. the Grooves can be oriented in the transverse direction or parallel to the axis of the sieve sections 110A-B. Preferably, the stepper coils shaped wire forming grooves screening sections 110A-B, although the screen sections 110A-B can also represent a rigid tubular element formed with grooves in it. Screen sections 110A-B may maintain an even distribution of flow across the area of the surfaces of the Sith. Curved rounded screen sections 110A-B, also provide the strength of the recipient 100 with trash sieve, having a low profile. Thus, the curved screen sections 110A-B may not require additional structural support structures in their internal spaces for the holding surfaces of the Sith.

As shown in figure 5, one form of construction for screening sections 110 is shaped wire 112 and the bearing blocks 114. In one embodiment, the carrying brusk the 114 along the sieve section 100, and shaped wire 112 is wound around and welded to the bearing bars 114 for forming the sieve section 110 using known techniques. Shaped wire 112 preferably has a wedge-shaped or V-shaped with the broader base of the wire 112, facing outwards to facilitate the sliding of sediment along the surfaces of the Sith. For example, the shaped wire 112 can be a VEE-WIREŽ from Johnson Screens. (VEE-WIRE is a registered trademark of Weatherford/Lamb, Inc.).

Another example of the receiving water 100 with trash sieve shown 6A-6C in Fig. This water body 100 has a screen sections 110A-B, the end wall 115A-B, the Central housing 120 and outlet 130 as described above. The ice machine 100 also forms a half cylinder, as shown in FIGU-6C. The recipient 100 with trash sieve can have closed or open base 117, as described above, for bearing on the upper surface of the platform.

In addition to these signs of the recipient 100 with trash sieve has an air pipe 140 for cleaning reverse flow and manifold 142, designed for cleaning reverse flow of water intake 100 with trash sieve through the blow-off air to the sediment. Air manifold 142 for cleaning reverse flow connected with an air pipe 140 for cleaning reverse the flow and is inside the sieve sections 110A-B and the housing 120. When using the pipe 140 and the collector 142 allow cleaning of the reverse flow of water intake 100 with trash sieve blowing air to remove sediment. These characteristics may be provided by a system Johnson Screen's Hydroburst System. In General, the Hydroburst system uses a compressor, tank, valves and controls to implement the purge air screening sections 110A-b In the periodic implementation, the air purge flushes deposits from the surfaces of the sieve.

In addition to the system for cleaning reverse flow water receiver 100 according to the present invention may include a flow modifiers, located inside the sieve sections 110A-B. flow Modifiers can be used with the system for cleaning reverse flow or without it. A more detailed description of the flow modifiers described below with reference to figa-7B and 8A-8B.

The intakes 100 with trash sieve, shown in figa-7B and 8A-8B, each has a T-shaped configuration with first and second screens 110A-B, connected to opposite ends of the Central housing 120. The Central housing 120 forms a hollow space 122 and has a semi-cylindrical side wall 124 and opposite the intermediate wall 126A-B. the Outlet 130 is connected with a hole 132 in the wall 124 and has a flange for connection with other components is AMI the water intake system (not shown). Both intermediate walls 126A-B have a Central hole 128 that receives the stream from one of the screening sections 110A-B. Both screen sections 110A-B have open ends are connected with the intermediate walls 126A-B enclosure, and a closed end wall 115A-B, which can be (or not) configured to discard the sediment. Each of the sieve sections 110A-B forms a half cylinder and has a lot of grooves for water input screen sections 110A-B, as described previously. Here also, the grooves can be oriented in the transverse direction or parallel to the axis of the sieve sections 110A-B. Preferably, the stepper coils profiled wire 112 form the grooves sit 110A-B, although sieves 110A-B may also be a rigid tubular element formed with grooves in it.

The Central passages 128 in the intermediate 126A-B walls may be sufficient to regulate the speed of flow on the surfaces of the sieves to maintain the preferred velocity of the surface flow. However, each intermediate wall 126A-B, preferably has a modifier 150 stream, located in the Central hole 128 for additional regulation of the flow velocity. In General, the recipient 100 with trash sieve can be used modifiers 150 flow having one or more tubes located in the holes 128 and partially within palaste the screening sections 110A-B, to create a message of the liquid from the internal spaces of the sieve sections 110A-B, through holes 128 in the hollow space 122 of the Central housing 120.

In the receiving waters 100 with trash sieve, shown in figa-7B uses a single-threaded pipe 160 for modifier 150 stream located in the holes 128. In the receiving waters 100 with trash sieve, shown in figa-8B uses a two-line pipe 170 and 180, is inserted into each other in the holes 128. In both configurations, the pipe 160 and 170/180 modifiers 150 flow can actually be a half cylinder with open or closed bottom surfaces, although it can be used completely cylindrical pipe offset from the center in the holes 128 in the intermediate walls 126A-B.

The recipient 100 with trash sieve and modifiers 150 flow figa-7B and 8A-8B are designed to reduce the velocity at the entrance to the slots of the sieve to the preferred peak value, which can be about is 0.135 m/s and 0.5 m/s in some embodiments, execution. Lower velocity at the inlet protects the surrounding aquatic flora and fauna and prevents clogging by sediment. Designers configure lengths, diameters, flow areas, and other variables pipes 160 and 170/180 modifiers flow to maintain the average flux through a surface is STI sit as close to the allowable peak flow rate and possible more evenly distributed along the surfaces of the Sith. When the modifier stream to use two pipes 170/180, as shown in figa, for example, a pipe of larger diameter 170 may be approximately 50% of the diameter of the sieve sections 110 and may be approximately 16% of the length of the sieve 110. Pipe 180 of a smaller diameter is inserted inside the outer tube 170 may have a diameter of approximately 70% of the diameter of the outer tube 170 and may have a length, which is approximately 67% of the length of the sieve 110. Additional details related to the design of modifiers 150 flow described in U.S. patent No. 6051131, which is included here in its entirety.
