    An apparatus for separating dust, dirt and the like from particulate material utilizes a flow of carrier fluid which passes through the particulate material on a grid or screen. The heavier particulate material falls through the grid while the lighter material as well as the dust, dirt and the like are entrained in the fluid and carried upwardly. A portion of the entrained material precipitates out of the carrier fluid into a vertical collecting bin whereupon it is discharged into another flow of carrier fluid. A sensor within the collecting bin senses the level of the collected precipitated material and reduces the velocity of the carrier fluid when the material in the collecting bin exceeds a predetermined level.

    2. The device according to claim 1, which is based on the fact that the device is equipped with valves installed at the outlet of the loading hopper and at the outlet of the collecting tank,
    Zch / device according to claim 1, of which the side wall of the collecting tank is installed
     with the possibility of vertical movement.
    4. Device POP.1, distinguished by the fact that the device is equipped with a centrifugal pneumatic dust collector connected to the ventilation openings by means of nozzles.
    The invention relates to a device for separating bulk & jpoB materials by specific gravity. . A device for separating bulk materials is known, which includes a grate, a pneumo-separation channel, an air supply device, loading and unloading devices 1. A disadvantage of this device is the low efficiency of the separation process. The closest to the invention by technical essence and the achieved result is a device for separating particles by specific gravity, including a grate located in the casing, a feed hopper mounted on the edge of the grate, a vertical air separator and an air supply unit for the air under the grate with C2J nozzles. A disadvantage of the known device is the low quality of the separation process. The purpose of the invention is to improve the quality of the separation process. The goal is achieved by the fact that a device for separating particles by specific gravity, including a grate located in the casing, a hopper mounted on the edge of the grate, a vertical air separator and ventilation units for air supply under the grate with nozzles, is worn on the edge of the grate, opposite to the loading hopper is a collection tank with a filling degree sensor and with an outlet opening which is in communication with the pneumatic separator. At the same time, the device is equipped with a rod with valves installed at the outlet of the loading hopper and at the outlet of the collecting tank. The side wall of the collecting container is installed with the possibility of vertical movement. In addition, the device is equipped with an centrifugal pneumatic dust collector connected to the ventilation installations by means of nozzles. FIG. Figure 1 shows the proposed device (General View; Fig. 2 - section A-A in Fig. 1. A device for separating particles by specific weight comprises a housing 1 with a hopper 2, a distribution capacity 3 and a grid 4. At the lower end A supply valve 5 is provided to the distribution tank 3. A screening-kada surface 6 is installed under the grid 4. At the edge of the grid 4 opposite to the loading core 2, a collection container 7 is installed, at the lower end of which there is a supply valve 8, the valves 5 and 8 are connected between each other 9. For; team capacity of 7 a pneumatic separator 10 is located. In the view above the grill 4 there are control valves 11 and 12, between which there is a partition 13, which changes: the direction of air flow. The pneumatic separator 10 is closed by a control valve 14. Behind the control, valves 11, 12 and 14 and the direction of the air the flow is a fixture .15 for separating the lighter particles, in which a burnout is installed. An ledge 16, which directs the airflow, carries lighter particles and dust, and a screw 17 for removing light particles. Behind the device 15, a centrifugal pneumatic binder 18 / is installed relative to the inner side of the wall of which a nozzle 19 is installed. The latter is connected to a ventilation unit 20. The centrifugal pneumatic dust collector 18 is serviced by two ventilation units 21 and 22, which are installed in The engines 23 and 24, installed on both sides of the casing 1, are connected to the grinding units 21 and 22 by means of nozzles 25 and 26, forming a closed air system. A regulating valve 27 is installed in the pipe 25, a regulating valve 28 is installed in the pipe 28.- 28. A filling sensor 29 is installed in the collecting tank 7, and an outlet 30 is connected, which communicates with the pneumatic sampler 10. The side wall of the 31 collecting tank 7 possibility of vertical movement. The device works as follows. Particles from the hopper 2 are fed to the inclined grid 4, where they are sieved by an air stream passing upwards. Heavier particles sink through the grate down to the screening surface 6. The lighter particles and dust are trapped by the air stream upwards. Since the grating.4 is installed obliquely, the bulk materials sweep, which results in the uptake of heavier particles by upward flow, especially with a large supply of bulk materials. These heavier particles, trapped upward by the air flow, together with the overwhelming amount of the part, related in their weight to the boundary region, fall into collection tank 7, which is mounted above the lower end of the lattice. The restricting wall 31 of the collection tank 7, facing the pit valve 5, can be installed at different heights, which roughly regulates the proportion of bulk materials entering the collection tank 7, which depends there the bulk material falls into the vertical pneumo. : separator 1-0, through which from below: part of the air flow goes upwards. At the lower end of the collection container 7, there is a supply gate 8, which defines a cross-sectional area that permits free-flowing from the collection container 7 to the pneumatic separator 10-. The light particles from the pneumatic separator 10 fall into the device 15 to remove the light particles, where they are deposited and removed by the screw 7.,; The fill level sensor 29 installed in the collection container 7 outputs a signal corresponding to the position of the level in the collection container 7. This signal controls the airflow through the grill 4. For example, the signal is sent to a frequency regulator that adjusts the frequency and, therefore, the number of revolutions of the engine, which causes the fan 20 to rotate. In this case, the regulation occurs in such a way that the number of revolutions of the Fan 20 decreases with increasing filling level of the collecting tank 7. When the filling level in the collecting tank 7 is lowered, therefore, it increases by the number of a fan 20. The air-borne note, passing from the bottom up to the worm 4, increases the level of Kjiti, like loosening of the bulk material. The feed dampers 5 and 8 serve to coordinate the delivery of the material to the grid 4 through the distribution tank 3 to supply it to the pneumatic separator 10, in order to be able to control the number of particles that fall into the collection tank, the latter has a side wall that faces - Vertical movement. For installation, adjustment and adjustment of the air flow between them, control valves are installed behind the grille and pneumatic separator, in the direction of the air flow, to regulate the cross-sectional area of the air flow pass. The use of the proposed unit for the separation of particles by specific gravity will improve the quality of separation.
