Problems solved by technology

[0003] In this way, the alumina will be concentrated near the projection surface of the expansion tank in the silo, and the storage space of the silo is restricted; due to the conical accumulation of alumina inside the silo, it is easy to cause granularity when it is discharged from the silo. The classification phenomenon, the concentrated discharge of large or small particles of alumina is not conducive to the electrolytic production

Abstract

The invention discloses a gas-solid separating device, and in particular relates to an alumina silo top multipoint blanking device on the top of a storage bin in an electrolytic aluminium plant and a blanking method thereof. The alumina silo top multipoint blanking device comprises a storage bin. The gas-solid separating device is arranged above the storage bin; a feeding pipe of the gas-solid separating device is connected with a conveying pipe; an exhaust pipe of the gas-solid separating device is communicated with the storage bin; and a blanking pipe of the gas-solid separating device is communicated with a splitter chute which is communicated with the storage bin. The gas-solid separating device has the advantages that through adopting the combination of the separating device and the storage bin, the device and the method improve the conventional blanking mode, realize the multipoint blanking of alumina on the silo top, effectively improve the storage space of the storage bin, reduce the alumina grading during deposition, and facilitate the electrolytic production.

Description

technical field [0001] The invention relates to a gas-solid separation device, in particular to a device and a method for discharging materials at multiple points on the top of an alumina silo in an electrolytic aluminum factory. Background technique [0002] In the existing alumina silo roof unloading device, the pipe is generally used to directly enter the storage silo or expansion tank. Alumina enters the expansion tank through the pipeline through the air lifter. Depending on the increase in the space of the expansion tank, the gas flow rate decreases, so that the alumina falls freely and sinks into the storage bin. [0003] In this way, the alumina will be concentrated near the projection surface of the expansion tank in the silo, and the storage space of the silo is restricted; due to the conical accumulation of alumina inside the silo, it is easy to cause granularity when it is discharged from the silo. The classification phenomenon, the concentrated discharge of lar...
