Filtering apparatus for air-driven chute

Abstract

The invention provides a filtering apparatus for an air-driven chute, comprising an air-driven chute (1); a discharging port at the bottom of a bin is connected with a manual clamping-type gate valve (3); the lower end of the manual clamping-type gate valve (3) is connected with a discharging slide pipe (2) which is connected with a filtering apparatus (4) consisting of a feeding box (11) and a slag-removing box (12); the left side of the feeding box (11) is connected with the slag-removing box (12); the left side of the feeding box (11) is connected with the slag-removing box; the lower end of the feeding box (11) is connected with an air inlet system (5); and the lower end of the slag-removing box (12) is connected with the air-driven chute (1). The filtering apparatus has reasonable structure, easy installation and simple manufacturing, can conveniently remove impurities and blocks in aluminium oxide materials at any time without dismantling any relevant equipment or parts, thus guaranteeing the smooth and uninterrupted conveying process.

Description

technical field [0001] The invention relates to a filter device, in particular to a filter device for a pneumatic chute. Background technique [0002] At present, the alumina in the aluminum electrolytic cell in the prior art adopts the ultra-dense phase conveying technology. In the process of use, it is installed in the pneumatic chute at the bottom of the fluorine-containing alumina bin, and its feed pipe directly passes through the discharge chute and manual control. The clamp-type gate valve is connected to the discharge port at the bottom of the silo, and there is no filter device installed in the middle, and a large amount of impurities and agglomerates are mixed in the fluorine-containing alumina material. After these impurities and agglomerates enter the pneumatic chute, due to their poor fluidity , It is very easy to cause the air chute to be blocked. Some manufacturers install filters with only one filter screen by themselves. The structure is too simple, and it i...

After these impurities and agglomerates enter the pneumatic chute, due to their poor fluidity , it is very easy to cause blockage of the pneumatic chute

Some manufacturers install filters with only one filter screen by themselves. The structure is too simple, and it is inconvenient to remove slag, and it also does not have the effect of filtering and removing slag.
