Utility Model Implementation

The utility model is implemented as follows. By means of the connecting means 2, the discharge tank 1 is connected with an unloading hole to the loading hole 3 of the intermediate vessel 4. A supply pipe 9 is connected to the outlet of the compressor 10. A supply pipe 9 is connected to the aeration device 8. with the end opposite to the connection with the compressor 10.

The shutter and the overlapping device 14 are placed in the open position. Bulk material under the influence of gravity is transported in the intermediate tank 4. When filling the intermediate tank 4, the bulk material displaces air from it, creating excessive pressure. In this case, the displaced air and bulk material do not enter the discharge pipe 11, which is blocked by the shutoff means 13. The displaced air passes through the tubular element 5 and the perforation in the base 6 and is discharged outside the device. In this case, particles of bulk material are retained by the tubular element 5 and are not removed from the intermediate tank 4. By installing an air discharge device in the upper part of the intermediate tank 4, excess air is also discharged from the intermediate tank 4 even when the intermediate tank 4 is filled to the upper level. After filling the intermediate tank 4, the shutter and the shut-off device 14 are turned into the closed position, and the shutoff means 13 are in the open position and the unloading cycle of the intermediate tank 4 is started. In this case, air is supplied to the aeration device 8 and, in a particular case, to the air discharge device under pressure. By flowing into the intermediate container 4 of the air, the particles of bulk material are transferred to a suspended state. Thus, a fluidized bed is formed. Overpressure is created in the intermediate container 4, as a result of which the bulk material, together with the air, enters the discharge pipe 11 and is transported to a container for storing bulk materials 12.

Thus, the implementation of the device in the manner described above provides an increase in the productivity of the device, by reducing the resistance to movement of bulk material by discharging excess air.
