A clamping and tightening device for an aluminum electrolytic cell

Abstract

A clamping and jacking apparatus of an aluminum electrolytic cell. A clamping frame (2) is provided around an aluminum frame (1) inside which several conductors are provided, and an anode lifting mechanism (3) used for adjusting the lifting and lowering of the clamping frame (2) is further comprised; several clamp holders (4) are provided between the aluminum frame (1) and the clamping frame (2), and at least one clamping wheel (41) is provided on a single clamp holder (4); several hanging plates (5) or at least one flexible chain (6) matched with the single clamp holder (4) and driven by the at least one clamping wheel (41) on the clamp holder (4) is further comprised; and a part of at least one of the hanging plates (5) or flexible chain (6) is maintained between the clamp holder (4) and the aluminum frame (1). The apparatus can reliably and stably clamp or lift / lower an anode while ensuring the aluminum frame (1) and the anode to be intact, keeps the contact voltage difference between an anode guiding rod and the aluminum frame (1) stable and low, and has a simple structure.

Description

Technical field [0001] The invention relates to the technical field of aluminum electrolysis, in particular to a clamping and tightening device for an aluminum electrolysis cell. Background technique [0002] The patent application number 201711220109.6 discloses a clamping frame of an aluminum electrolytic cell, in which several wheel clamps are arranged on the top or groove of the clamping frame, and the pressure clamp applied to the anode by the wheel clamp Hold and lift the anode, and can rely on the movement force generated by the rotation of the wheel holder to drive the anode up and down to lift the anode to a specified position. The clamping wheel in the wheel clamp is generally in linear contact with the aluminum frame. Under the condition that the clamping wheel exerts a certain pressure on the aluminum frame, due to the small contact area between the clamping wheel and the aluminum frame, the pressure on the aluminum frame is Very large, it will damage the aluminum fr...

AI Technical Summary

Problems solved by technology

[0003] The present invention solves the problem that the wheel clamper applies too much pressure to the aluminum frame, easily damages the anode, and adding conductive fillers between the anode guide rod and the aluminum frame or at the lower end of the anode guide rod will increase the workload and operating costs. The problem is to provide a clamping and tightening device for aluminum electrolytic cells, so as to realize the reliable and stable clamping of the anode under the premise of ensuring the integrity of the aluminum frame and the anode, the anode lifting operation is highly mechanized and automated, and the anode is controlled The lifting operation precision is high, the contact voltage between the anode guide rod and the aluminum frame is reduced and the structure is simple, no arc is generated when the relative displacement between the anode guide rod and the aluminum frame occurs, and the purpose of the anode guide rod not moving in the left and right direction
