with a screw feeder 18 washing devices.

The flushing device is made in the form of a vertical drum 19 connected to a drive (not shown) with inclined vanes placed in a spiral and with a fan 20 placed on a drum 19 located in a cylindrical tank 21 provided with a screw feeder 18 in the lower part perforated section 22 and discharge port 23 in the upper part and sprays 24 of the washing liquid in the middle part. Moreover, the perforated portion 22 of the cylindrical tank 21 is installed at the level of the fan 20 placed on the drum.

The line is also equipped with a cyclone 25 with an inner mesh casing 26 and a drainage hole 27, which is mounted between the flushing device and the pneumatic transport device and connected in the upper part to the discharge outlet 24 of the flushing device, and in the lower part to the fan 28 of the device pneumatic transport Duct 29 is connected to a hopper 30, made in the form of a truncated pyramid, facing upwards with a large base, on which a cylindrical material receiver 31 is mounted, connected to air duct 29 ARISING pneumatic conveying. In the smaller base of the pyramid 30 there are two hatches 32 and 33 with covers 34 and 35, respectively, installed with the possibility of tilting down at an angle not less than the angle of repose of the material.

Under the accumulators there is an agglomeration device, equipped mainly with 36 and an additional 37 vertical

cylindrical containers with 45 flushing devices are placed, and the liquid is pumped inside them with blade shafts 38 and 39, respectively, with cutting elements 40 and 41 at the ends of the blades. Main 36 and extra

shown). The containers 36 and 37 are rotated. Under the action of the blades of the drum 19, there are discharge outlets one to the other - the film rises. The flow of it 42 and 43 and connected to the common tray is washed by the water supplied from the spray 44 to the auger conveyor 45 and 55. 24. In the zone acting by pneumatic transport 46, which supplies the fan 20, the film is captured by the agglomeration device. The discharging nozzle 23 ejects the openings 47 and 48 of the tank 36 into the cyclone 25, where, with air flow, it and 37 are located directly under pressed against the mesh casing 26.

hatches 32 and 33. Pneumatic transport 46 is connected to the Ounker 49, equipped with a stirrer 50.

The line is also provided with a pallet 51 located under the perforated bottom 8 of the discharge chute 7 of the crushing device 1 and a bag filter 52.

Lini works as follows. The raw material in the form of panels of a contaminated film, for example polyethylene, is fed through a loading opening 5 into a crushing device 1, where it is caught by a paddle shaft 2 and crushed by cutting elements 3. At the same time, water is fed into container 4. The material crushed to a certain extent and pre-wetted through the grate 6 enters the tray 8, where it is picked up by the scrapers 10 of the drum 7. The peripheral speed of the scrapers 10 exceeds the linear velocity of the exit through the grate

5 6 of the material ensures the absence of clogging of the grill 6. The scrapers 10 pull the material along the perforated bottom 9 of the tray 8, while the gr of water coming out of the container 4 flows into

the tray 51, and touching the perforated bottom 9 with scrapers 7 causes the liquid dirt left behind on the film to be partially scraped off and also goes through the hole in the perforated bottom 9 into the tray 51. The material is scraped into the smaller compartment of the device bath 11 through the perforated bottom 9 remove impurities. The flow of water created by the pump 17, the film is carried forward.

0, through the partition 12, moves to overflow 15, through which the washing device 18 enters the inlet feeder 18. The feeder 18 transports the film to the bottom of the container 21 mouth5

pump 17 through line 16 to the smaller compartment of bath 11. In this case, additional mixing of the film and liquid takes place in the feeder 18,

which provides additional washing.

During the descent period inside this iryca core, the maximum possible separation of moisture occurs, which flows into the drainage hole 27. The film goes down from the film and is caught by the fan 28 and fed through the duct 29 to the receiver 31, from where it enters the accumulator 30 "When the accumulator 30 is filled, the operator automatically or manually alternately fold the covers behind and 35, while opening the hatches 32 and 33, respectively. When opening the hatch 32, the cover 34 is thrown at an angle not less than the angle of repose of the material, which ensures unhindered The ventilator unloads the film into the container 36 of the agglomeration device through the opening 47, while the cover 34 is folded back to form a stream that guides the film into the container. Having filled the container 36, close the cover 34, open the cover 35, thereby opening the hatch 33, and load the container 37 through the opening 48, after which the cover 35 is closed and the drive is refilled. During the accumulation time in each of the tanks 36 and 37 of the agglomeration device, evaporation of the residual moisture and agglomeration occur in accordance with the known process conditions.

When agglomeration occurs in a known manner, it is interrupted alternately in containers 36 and 37, opening the covers 42 and 43, and the agglomerate is unloaded into the pan 44 under the action of the rotating shafts 38 and 39, and then the covers 42 and 43 are closed and the loading of the containers 36 again takes place 37 The material discharged into the pallet 44 is transported by the screw 45 at the entrance to the pneumatic transport 46, which feeds it into the bunker 49, where, stirring with the stirrer 50, is averaged. From the bunker 49, the agglomerate is fed for processing into pellets or products. The dust fraction carried away by the transporting air is captured by a bag filter 52. (

The proposed line in comparison with the known one allows to reduce power by 35%, the number of drives by 20%, and to reduce mass by 43%. Separating the agglomeration device into two tanks allows unifying the drives, nodes of the agglomeration devices, washing and crushing
