We offer disc separator refers to a grain cleaning machines used to clean the grain material from short, long and mineral impurities and dry cleaning of the surface of the grain.

Known working body of the separator, consisting of a rotor disk, spokes, Hankow and cellular segments, provided with a through-hole of circular cross section, fixed to the disc on both sides. Through holes of the cells has a diameter of 2-6 mm, and the surface of the disk forms the bottoms, while the axis of symmetry of the cell is tilted to the surface of the disc at an angle α=75-90°, and the radius β=80-90° (A.S. No. 980865, M. CL. V In 13/02, publ. 1982, bull. No. 46).

However, the shape and size of cells known separator based upon the shape and size of grains inseparable short of impurities (cockle), provide for the filling of the cells only kernels of these impurities and their removal in the bore of the pipe precast-output device (IED) separator.

Known production disk puppet A9-duck-6 and sugny A9-UTO-6 screening applied to processing companies for cleaning wheat from the cowl and wild oat (see Ayatollas. Technological equipment of enterprises for storage and processing of grain. - M.: Kolos. S-121).

Significant disadvantages of treerow are the following: first, is arnosti equipped with cells only for filling and removal of caryopses short or long fractions in IEDs Trier secondly, long grain fractions periodically return to the layer of the processed material, enriching its initial concentration at the beginning to 100% at the end of Trier. For example, in puppet Trier initial concentration of impurities short (cockle) at the beginning of Trier is about 3%, and by the end, by taking grains of cockle cells, there is a complete enrichment layer of long grain fraction (wheat) to 100% and at the end of Trier comes clean grain. As a result, the utilization factor of the honeycomb surface low is ε=0,035 0,03...and performance decreases significantly puppet Trier. In osogna Trier initial concentration caryopses long fraction (wild oat) in the beginning is about 3% and the end, by taking wheat cells, the concentration of wild oat reaches 100%. As a result, the coefficient ε=0,16 0,18...(see Ayatollas. Technological equipment of enterprises for storage and processing of grain. - M.: Kolos. 1984. Pp.118-119), which is also the reason for the low performance of this Trier. Drawbacks associated with the process of the disk Trier disks which have cells only for the removal of grains short of a faction of the periodic return of long grain fraction from the porous surface layer of the processed material, which leads to his obog is against the grain of the long faction. For example, in osogna Trier with wild oats from 3% concentration at the beginning to 100% at the end of Trier, which reduces its effectiveness. In addition, existing tierah the location of the boot socket on the left side of the shaft at the beginning of the Trier does not provide a reasonable supply of source material for receiving and scratch disks. Because the material is fed against the direction of rotation of the discs and enters the area fill the cells with the grain only after the passage of the upper layer to the lower edge through the area of its longitudinal transportation races disks. This reduces the intensity of the fill cells with short grains fraction and, consequently, the process of cleaning the grain in Trier.

The closest in technical essence and the achieved result of the present invention is a disk Trier-osgoodby, including within the enclosure on a common shaft receiving workers and working mesh rims with racing and separate transport of the race, the top and inter screen guide plates, boot and precast-output connections. Cell drive in Trier-osgoodby made oblong, shapes and sizes are established in accordance with the shape and size inseparable oats, and provide sustainable Zapadnye and removal of long grains admixture, a component usually 3% in the original the grain, in the hole of the socket SVU separator, reducing the amount of work wire mesh surface for removal of wild oats and increase the performance of the separator. (RU # 2212955 C1, MPK7 V In 13/02, 13/16, publ. 27.09.2003. Bull. No. 27).

However, increasing performance Trier occurs only when the removal of long grains admixture (wild oat), is contained in the original grain material is about 3%, and is not used in it the possibility of simultaneous removal of caryopses short impurity (cowl) from the layer of the processed material in the bore of the pipe precast-output device (IED) for impurities.

The content of the cockle in the original grain is also about 3%, i.e. the total content of short and long impurities in the original grain is about 6%. Therefore, the supply of disks alternating segments with cells for cockle or oats will provide simultaneous removal of short and long grains of impurities cell surface.

For the realization of technological process of cleaning the grain with simultaneous removal of the mesh surface of the long and short of impurities it is necessary to supply the cellular surface cells for cockle and wild oat. This will provide an increase of the coefficient of the honeycomb surface two times and a corresponding increase in the performance of the separator, i.e. instead of two (puppet and Oswego) treerow in existing if the AI management of grain will be applied to work one separator, providing simultaneous purification of grain from cockle and wild oat. In addition, in known disk osgoodby not used the possibility of effective location of the loading branch pipe and not been determined location of the outlet for grains and pebbles in its rear wall for the intensification of grain from short, long and mineral impurities.

Thus, the technical problem of the invention is the development of wire mesh disc surface of the separator, which should be provided by cells, each of which is established in accordance with the shape and dimensions of the long and short of impurities, and would provide a sustainable Zapadnye and removing grains only impurities from the layer of the processed material in the hole IEDs, and the gathering of purified fractions of wheat grains and pebbles from the housing at the end, and the location of the boot socket on the right side at the beginning of the separator so that the filing of the original material was produced in the active zone of processing two receiving and scratch disks during rotation.

The technical result of the invention is to provide sustainable populate cells drives short and long grains of impurities and their simultaneous removal and drop into the hole of the socket IED waste, and output the cleaned grain and mineral impurities, in the context of the s separator.

This technical result is achieved by the fact that in the known disc separator, including within the enclosure on a common shaft receiving workers and working mesh rims with racing in their spokes, the upper inter guides zhelobkovye plate, the device lower inter guides stamped sit, receiving and sorting slanted inter stamped screens, nozzles for discharging the cleaned grain, boot and precast-output devices, according to the invention the cellular surface of each disk from both sides supplied with alternating segments with cells for cockle or wild oats, boot tube installed on the front end side of the housing on the right side of the shaft under the pipe precast-output devices (IEDs), while in the lower wall of the housing in the recess in the form of gutters installed screw device for output of mineral impurities, spiral surface which forms an angle of 15...20° to its axis.

Distinctive features of the proposed disk separator compared with the prototype is that the cellular surface of each disk consists of segments, each of which is equipped with cells for cockle or wild oats, and segments with cells for cockle are interleaved with segments with cells for wild oat, i.e. the number of them on one disc Odin the TV. This provides a stable cell padding kernels short or long impurities and their simultaneous removal of the mesh disk surface layer of the processed material and drop into the hole IED for waste fractions (About). In addition, the boot nozzle disk separator is installed on the front end side of the housing on the right side of the shaft under the pipe IEDs and forms a channel for supplying the source material in the area of the two first receiving scratch disks (in the direction of their rotation), using the space under the pipe IEDs for impurities. Thus, the initial material is fed directly into the area active processing of the two first receiving disks and intensely moving races to the next disk.

When the supply of the source material on the right side at the beginning of the separator in the direction of rotation of the rotor disk all ten discs, including two receiving workers and 8 workers, provide simultaneous removal of short and long grains of impurities cells in IED waste and complete cleaning layer of the treated grain in the process of moving it races along the disk of the rotor from the beginning to the outlet pipe for purified grain. The hole has a rectangular shape whose side is a=d2-d1where d2- outdoor and d1the inner diameters of the annular disk surface. the internal lateral side of the hole is located at a distance - C=(0,9...1,3)and from the vertical diameter, and its upper horizontal side at a distance b=(0,8...1,2)from a horizontal diameter of the disk. These parameters are outlet openings defined by the value of the elevation angle of the front edge of the rotating grain layer in the separator.

In the process of moving grain layer races from the beginning to the end of the housing of the separator pebbles as heavy impurity, is deposited in a layer and is provided on a bottom surface of the housing. Thus, the maximum angle α lifting pebbles from rotating layer is located below the outlet pipe for purified grain. Therefore, pebbles misses flow Meters cleaned grain from the hole, and for the collection and release of pebbles from the housing to the end of its bottom wall is a slot in the form of a trough with a screw device. The spiral surface of the screw forms with its axis angle equal to 15...20°, which provides longitudinal movement of particles pebbles to the outlet, and the grain is thus rotated and thrown by the auger from the gutter, distraught rotating layer, is carried away to the outlet for the cleaned grain. The design and operation parameters of screw devices provide longitudinal movement of pebbles and do not differ from the known.

Technological process in which the removal of the short is long impurities cells working surface of the disc in the hole IED when moving layer of material to be processed races along from the beginning to the end of the separator emitting pebbles in a separate outlet, provides dry cleaning the surface of the grain, the currently executing in a separate grain peeling machine.

Thus, a new set of listed design features of the claimed device located in relation to each other, ensures the achievement of the technical result consists in providing simultaneous removal of short and long grains of impurities corresponding to the set drive slot in the bore of the pipe IED to waste and this ensures the intensification of the cleaning of the grain material from cockle and wild oats, pebbles and dry surface treatment of grain in a single disc separator, increase performance, clean grain from short and long impurities in two times and a corresponding reduction in material and energy intensity of the separator compared with existing separators. In addition, there is an additional cost saving of material and energy through the combination of clean grain from impurities in length with the determination of mineral impurities and dry its surface in the same machine.

The essence of the proposed disk separator is illustrated by drawings, where figure 1 is a schematic cross-sectional view of the separator; figure 2 - layout of the honeycomb segments with cells for cockle and oats on the disk; figure 3 is a longitudinal section of the separator.

We offer disc separator contains installed in the housing 1 receiving workers and workers porous disks 2, mounted their hubs on a common shaft 3. The cellular surface of each disk 2 from both sides is formed by alternating segments 4 with cells for cockle 5 or oats 6, i.e. on the same drive as the number of segments with cells for cockle equal to the number of segments with cells for wild oats. Of the ten wire mesh discs two work as a foster-workers, and other workers.

Cell 5 for cockle have in terms of circular shape with a diameter of 2-6 mm, you can use the standard puppet cells type I-5 with a working size l=5 mm (see Ayatollas. Technological equipment of enterprises for storage and processing of grain - M Coles. S.112). Cell 6 for wild oat is made oblong, shapes and sizes are established in accordance with the shape and size of grains inseparable oats (see EN No. 2212955 - prototype).

Boot the pipe 7 for supplying the source material is located at the beginning of the separator on the right side of the shaft 3 on the front end wall 8 of the housing under the pipe 9 IEDs and forms a channel through the hole CDEF for feeding material into the zone of operation of the first two disks 2 in the course of their rotation, as shown in figures 1 and 3. The pipe 7 has a suction node 10.

At the end of the separator to the left of the vertical diameter, the RA drive 2 is the pipe 11 to release the cleaned grain, the outlet opening 12 which has a rectangular shape with width a=d2-d1where d2outside, a d1the inner diameters of the annular surface of the disk 2 (see figure 1). The upper outlet end 12 of the socket 11 are parallel to the horizontal diameter of the disk 2 and is situated at the distance b=(0,8...1,2)a, and the inner lateral side at a distance of c=(0,9...1,3)from a vertical diameter of the disk 2. Before the pipe 11 during the rotation of the discs in the lower wall of the housing 1 in the recess in the form of gutters installed screw device 13 for outputting mineral impurities (pebbles). The device 13 has a screw diameter d=30-50 mm, length l=300 to 400 mm and is located at a distance c'=(0.3 to 0.8)from a vertical diameter of the disk 2. The spiral surface of the screw forms with its longitudinal axis an angle equal to 15-20°.

The separator is equipped upper inter guides Gelashvili plates 14 mounted inclined to the horizontal diameter of the disk 2. In the lower part of the housing 1 is device 15 of the lower inter guides stamped baskets, mounted on its base on the inner surface of the housing 1, and the free ends to the inner annular surface of the disk 2. On the spokes of the disk there are 2 race 16. After receiving the working disk 2 between the work disks installed additional radial lopa the local race 17. Between receiving the working disks 2 in the layer of the processed material obliquely installed device 18 in the form of receiving and sorting inclined inter stamped sieves consisting in length from the open sieve and parts. The device 18 is installed the upper end of the open part on the inner surface of the housing 1 and the middle part is fixed on the shaft 3 of the rotor disk. Sieve the part of the device 18 starts from the inner circumference of the annular disk surface to its lower end.

Disc separator works in this manner.

Initial grain material to be treated is loaded through the pipe 7 into the housing 1 of the separator. Through the channel CDEF source material is fed directly into the area active processing of the two first receiving workers disk 2 in the course of their rotation, moves the races the following discs. Long impurities (oat) steadily sink into the cell 6 segments 4 with cells for wild oats in their motion in the layer of the processed material and are removed from the layer, and fall into the hole of the socket 9 SVU, how come in the form of waste "On". At the same time long impurities is drawing short of impurities (cockle and Tatar of Grechesky) cells 5 segments 4 to cockle, removal and drop them into the hole of the socket 9.

The shape and dimensions of the cells provide only capture long primase the cells 6 and short cells 5 of the disk (see 2).

The device 14 sends a grain of wheat, thrown from wire mesh disc surface, the layer of material to be processed in the same way as it was in Trier-osgoodby in patent No. 22112955.

Sieving device 15 and 18 have the same function as known in Trier-osgoodby (prototype). The open part of the device 18 provides the passage of the layer, moving from the ring wire mesh surface of the disc, the screen mesh, which directs the oats to the lower end of the grain layer to capture the surface of the disk and fill the cells 6. The lower inter sieve device 15 in the layer directs the oats to the surface of the disc, short impurities from the zone transportation of grain races are held, as relatively small particles, in the zone of movement of the layer on the honeycomb surface of the disc and fill in the cells 5.

The grain of the main fraction (wheat) can't consistently catch in shallow oblong cells 6 and round cell 5, fall out with them back in the layer of the processed material, intensely moving races 16 disks 2 and additional radial-vane racing 17 layer along the rotor to the hole 12 of the socket 11 and go in the form of cleaned grain "M" (figure 1).

When moving a processed layer of grain races by the end of the separator housing 1 pebbles as heavy impurity, is deposited in a layer to the bottom surface the tee housing, falls into the gutter, where the set screw device 13. The spiral surface of the auger provides longitudinal movement of pebbles to the outlet in the flow of pebbles "G" (figure 1). The grain is thus rotated and thrown by the auger from the gutter, distraught rotating layer, is carried away to the hole 12 for the cleaned grain.

We offer disc separator can be created in terms of machine-building plants of the Republic and will provide significant economic benefit through the implementation of cleaning processes of grain material from cockle, wild oats, pebbles and dry machining the surface of the grain, ongoing in four separate existing machines, single disc separator. The creation of such a unified separator is a solution of the great problems in creating effective technologies and means of processing of grain and is of great scientific and economic importance not only in our country but also abroad.

Thus, the proposed design of the honeycomb surface of the disc, boot device, ensure the supply of the source material directly into the zone of active processing and separation of grain, to define the location of the outlet openings for the nozzles of the purified fractions of grain and mineral impurities while maintaining the location of ST is known disk Trier-osgoodby for short and long impurities in the disk separator ensure the intensification of the processes of simultaneous cleaning of the grain material in the disk separator from short and long impurities, pebbles and clean the surface of the grain, improving its performance in two times in comparison with the known separators, a corresponding reduction in their material and energy intensity by integrating processes clean grain from impurities in length with clean pebbles and dry surface treatment. This allows to make a conclusion on the compliance of the claimed invention, the criterion of "industrial applicability".
