CN2717982Y - Gravitational equilbrium stock column - Google Patents

Abstract

The utility model discloses a gravitational balance stock column used in the pressure balance device of the pneumatic chute of an aluminum electrolysis tank. The length H of a pressure balance pipe is 2000mm<=H<=3000mm, and the side face of the pressure balance pipe is connected with an exhaust pipe which is communicated with the pressure balance pipe through an inclined pipe. The utility model makes use of the gravity principle to make the material on the certain height automatically fall back into the pneumatic chute. When the gas in the chute gradually boosts and enters into the lower port of the pressure balance pipe in the process of using, the material clamped in the gas can fall back into the pneumatic chute on the corresponding height under the action of gravity, the gas can continuously rise to enter into the exhaust pipe, so the exhausting gas can be prevented from clamping the alumina material. The utility model has simple structure, and makes the gas exhausted from the pneumatic chute not clamp the alumina material.

Description

Gravity type boat davit balance stock column

Technical field:

The utility model relates to a kind of gravity type boat davit balance stock column that is used for aluminium cell air-driven chute pressure equaliser, belongs to aluminium cell air-driven chute pressure equaliser technical field.

Background technology:

At present, aluminium cell air-driven chute pressure equaliser of the prior art is in the process of using, owing in air-driven chute pressure equaliser expellant gas, carrying a large amount of alumina materials secretly, therefore existing aluminium cell air-driven chute pressure equaliser exists the shortcoming that material can overflow from its vapor pipe in a large number, this not only pollutes the environment, but also has caused unnecessary waste.

Summary of the invention:

The purpose of this utility model is: provide a kind of simple in structure and can prevent to carry secretly from the air-driven chute expellant gas gravity type boat davit balance stock column of alumina material, to overcome

The deficiencies in the prior art.

The utility model is to constitute like this: it comprises pressure equalizing pipe (1), the length H of its pressure equalizing pipe (1) is 2000mm≤H≤3000mm, and is connected with a vapor pipe that communicates with it (2) in the side of pressure equalizing pipe (1) by tipping tube (3); The angle β of pressure equalizing pipe (1) medullary ray and tipping tube (3) medullary ray is 15 degree≤β≤45 degree, and the intersection point of pressure equalizing pipe (1) medullary ray and tipping tube (3) medullary ray is 120mm≤h≤200mm to the distance h of pressure equalizing pipe (1) upper port.

Owing to adopted technique scheme, the utility model utilizes gravity principle, and material is fallen after rise on certain height in the moving chute of air intake automatically.When using the utility model, when the gas in the chute raises when entering the lower port of pressure equalizing pipe (1) gradually, the material of carrying secretly in the gas will be dropped in the air-driven chute in the effect of gravity on corresponding height next time, gas then continues to rise and enters in the vapor pipe (2), can realize gas solid separation like this, thereby prevent that expellant gas from carrying alumina material secretly.Therefore the utility model is compared with existing aluminium cell air-driven chute pressure equaliser, the utlity model has simple in structure, and the advantage that can not carry alumina material secretly in the air-driven chute expellant gas.
