Novel-structure cathode conductive rod rust removal module, device and system

Abstract

The invention discloses a novel-structure cathode conductive rod rust removal module, device and system, relates to the technical field of nickel sulfide diaphragm electrolysis, and solves the technical problems of incomplete rust removal and frequent replacement of a steel brush in the prior art. The rust removal module comprises a steel brush fixator and a rolling brush assembly, the steel brush fixator comprises a top plate and a side end supporting assembly, the side end supporting assembly comprises a rotating bearing assembly, a guide plate and a spring telescopic rod, a radial sliding groove is formed in the guide plate, one section of a mandrel of the rolling brush assembly is located in the radial sliding groove, and the end of the mandrel of the rolling brush assembly is in rotating fit with the rotating bearing assembly. According to the rust removal module designed by the invention, the surface of a conductive rod is smoother, the conductivity is better, the number of burnt plates is reduced, the grade rate of electric nickel is improved, and the power consumption is saved; and based on a spring telescopic rod, the rolling brush assembly can be adjusted in the radial direction of the conductive rod, then the abraded size of a steel brush is compensated based on the elastic telescopic amount of the spring telescopic rod within a certain range, the service life is prolonged, and the maintenance frequency and the maintenance cost are reduced.

Description

technical field [0001] The invention relates to the technical field of nickel sulfide diaphragm electrolysis, and more specifically relates to the technical field of a new structure cathode conductive rod derusting module, a derusting device and a derusting system thereof. Background technique [0002] The original design of the conductive rod unit has the functions of automatic cleaning, rust removal, storage and transfer of the cathode conductive rod. However, since the unit was put into use, the actual cleaning effect of the ultrasonic cleaning device on the conductive rod is not good, and cannot meet the production and use requirements. In view of this, a conductive rod automatic rotary milling and polishing device is added to the conductive rod supply device between the conductive rod unit and the preparation unit, but this device uses a roller to drive a flat steel brush, and the steel brush removes the cathode conductive rod by rolling and rotating.

AI Technical Summary

Problems solved by technology

However, since the unit was put into use, the actual cleaning effect of the ultrasonic cleaning device on the conductive rod is not good, and it cannot meet the production and use requirements.

In view of this, a conductive rod automatic rotary milling and polishing device is added to the conductive rod supply device between the conductive rod unit and the preparation unit, but this device uses a roller to drive a flat steel brush, and the steel brush removes the cathode conductive rod by rolling and rotating. Surface oxides and solution crystals and other sundries, when the drum rotates to drive the steel brush to derust and polish, the steel brush head will be worn out soon, which will shorten the steel brush wire, and the remaining steel brush wire cannot contact the surface of the conductive rod, resulting in Incomplete grinding and rust removal, frequent replacement of steel brushes, etc.
