Method controlling cell voltage of electrolytic cell and clamping frame position

Abstract

The invention relates to the technical field of aluminum electrolysis, in particular to a method controlling a cell voltage of an electrolytic cell and a clamping frame position. The technical problems that an existing cell voltage and clamping frame position control method is not reasonable, operation for lifting a clamping frame is complicated, and efficiency is low are solved. A device in use comprises a clamping frame and at least one aluminum tube anode arranged in the clamping frame and internally provided with a plurality of conductors; the aluminum tube anode comprises an aluminum tubein which the plurality of conductors in contact with the aluminum tube are arranged; at least one anode lifting mechanism connected with the clamping frame and used for adjusting the cell voltage isfurther included; the clamping frame is provided with a plurality of first pressing mechanisms in contact with the aluminum tube; at least one detecting unit is arranged around the clamping frame, andthe detecting unit, the first pressing mechanisms and the anode lifting mechanism are all connected with the control system; and a cell voltage signal of the electrolytic cell is acquired and input into the control system.

Description

technical field [0001] The invention relates to the technical field of aluminum electrolysis, in particular to a method for controlling the voltage of an electrolytic cell and the position of a clamping frame. Background technique [0002] The patent application number 201711220109.6 discloses a clamping frame of an aluminum electrolytic cell, which is lifted to a specified position by relying on the pressure and motion force applied to the anode by the movement of the clamping wheel; the patent application number 201810158781.5 discloses A clamping and tightening device for an aluminum electrolytic cell, relying on the pressure and motion force applied to the anode during the operation of the hanging plate or flexible chain between the clamping wheel and the aluminum frame, and the huge friction between the two to clamp The frame is raised to the specified position. When the above two technologies are used to lift the clamping frame separately, it is easy to cause cell vol...
