The invention is intended for the separation of bulk materials of fibrous structure, such as peat, as well as other materials with fibers and

grains of the extended form. I

The purpose of the invention is to improve the quality of the separation of fibrous peat.

1 shows a diagram of the device, a longitudinal section; 2 shows the grate; FIG. on fig.Z - section bb in figure 2.

The separation device comprises a frame 1 with brackets, in bearings of which two shafts are installed in parallel, an eccentric shaft 2 with bushings and rigidly connected to the frame 1, a concentric shaft 3 with bushings that are connected between hinged shaft hubs 2 and 3 hollow grates ( buttons) 4, in the rear part of which a removable plug (plug) 5 with fitting 6 (air supply unit) is inserted, and transverse lugs 7 are made on the surface 7. Between them there are blower holes with decreasing in the direction reset peat di- ametrom, wherein vel rchina diameter of the first opening 8 is d, the second openings 9, d, 1 / 2d; the third hole is 10 d, and the half hole is 11 d 1 / 4d. In the front part of the grates 4, seals — 12 — are installed, into which longitudinal hollow cantilever kosirkas 13 with blower holes 14, directed upwards, are placed longitudinally hollow with a blind end 15, keeping a 15 with a lock 15 in the grates 4. A camera 16 sec is fixed on the side frames of frame 1 air inlets 17 for suctioning air with thin fractions in communication with channel 18, one end of which is connected to confusor 19 with an axial fan 20, and the other end channel 18 through a precipitator 21 communicates with lower section 22 of pallet 23. A collection of 24 products of separation of races laid below the grates 4, the front part of which is covered by an elastic apron 25, and the rear part is closed by an elastic apron 26. The aprons are attached to the chamber 16, on top of which is installed the loading device 27, the compressor 28 with the drive and the tank 29 for compressed air. Pipeline 30 through the collector 31 tank 29 is connected with fittings 6. The eccentric shaft 2 is connected to the drive 32. London 23 is installed with a slope greater than the angle of friction between the peat and the bottom material of the pallet 23, i.e. at an angle of 30-40 °. The cross-sectional shape of the grate 4 may be rectangular, triangular and round. Under the grate 13 fixed collection of 33 products of separation, and the tank 29 can be performed with an air heater.

The longitudinal grates 4 and 13 form successively located along the length of the chamber 16 of the part of the separation surface located under the loading device, the blowing holes are sequentially arranged along the length of the grates. Shafts 2 and 3 with sleeves form the exciter of the separation surface. Convexity 7 in series 1 D

TO wives of length K (1 grid (1 1 4). Kolpins 13 are installed telescopically in grates A. Separation product collections are located under each part of the separation surface, and the air supply unit communicates with the grate cavities .4, with their end portions opposite to the grates 13.

The device works as follows.

Turning on the actuator 32, the eccentric shaft 2 is set in rotation, which drives the grate A. The front end of the grate 4 together with the grate 13 makes a circular movement, any point of the grate 4 and 13 moves around the circumference, and the rear end of the grate 4 makes swinging movement arc of a circle. From the device 27, slightly decomposed peat with a degree of decomposition from 5 to 25%, previously dried to a moisture content of 20-55%, flows in portions to the surface of the grate 4, forming a thin layer (within 40-60 mm). By interacting with the moving grate 4, small pieces are separated from the fibrous inclusions of peat, fall into the holes formed by the adjacent grate 4, and enter the collection 24. Here they accumulate and then slide into a container (not shown).

HenpoceHHHbtfi fiber peat and puschitsa, interacting with the grates 4, are tossed up and simultaneously moving in the direction of the collector 33. At the same time, small pieces of peat fall out of the peat, which also enter the compilations 24. However, with such interaction with the grate 4 of the fibers, cotton fluffy does not fall out. However, when compressed air is supplied through conduit 30 through manifold 31 and fitting 6 to hollow grates 4, it leaves the internal cavity of grates 4 through openings 8-11 and through openings 14 of grates 13 in the form of a torch with a different pressure.

At the same time, interacting with the fibers and cotton grass, the air coming out of the hole 8, penetrates these fibers and cotton grass with great penetration, partially blowing them to a small height. In this case, the peat located between the fibers and cotton grass is blown out by this dust in one upward direction. Fibers and nv-

This ensures that the required pressure of the jet of air coming out of the openings of the grates 4 and 13. The equal size of the openings 14 of the grates 13 ensures the same conditions for the interaction of the air on the T-pipe n11np | peat. The warbler and the puigits, freed from dust, fall through the gap formed by the adjacent 1b and grate 13, and fall into the collection 33. In this part

fibers and cotton grass, not provapivsha c in the specified 1, is dropped from the end of the grate 13 into the collection 33, and the lock 15 reliably holds the grate 13 in the grate 4. The position of the pan 23 with a slope improves the rolling of the material. With the supply of heated air, there is a partial drying of dust and fibers, thereby improving the condition for removing dust from the fibers and cotton grass.
