Zinc electrolysis negative plate scrubbing unit

Abstract

The invention discloses a zinc electrolysis negative plate scrubbing unit. The zinc electrolysis negative plate scrubbing unit comprises a transverse plate moving and transmission system and a plate scrubbing machine; the transverse plate moving and transmission system comprises a chain wheel and chain assembly; a driving head is arranged at each of the two ends of the chain wheel and chain assembly; the chain wheel and chain assembly is supported through a chain supporting upper beam, a chain supporting lower beam and a supporting vertical beam; the chain wheel and chain assembly is providedwith negative plate hooks; negative plates are hung on the negative plate hooks; the transverse plate moving and transmission system is provided with an input station, a vibrating station, a pre-stripping station, a manual intervention station, a main stripping station, a scrubbing station and an output station of the negative plates; the plate scrubbing machine is arranged at the scrubbing station and comprises two brush wheel assemblies; and two brush wheels are synchronously opened and closed through a connecting rod and a synchronizing mechanism. Accurate location, synchronous plate clamping and rapid plate scrubbing of the negative plates can be realized, and the scrubbing effect is better.

Description

technical field [0001] The invention relates to an electrodeposition metal stripping device, in particular to a zinc electrolysis cathode plate scrubbing unit. Background technique [0002] The output of metal zinc is mainly divided into two categories: hydrometallurgy and pyrometallurgy. At present, most zinc smelting enterprises use hydrometallurgy, that is, the method of electrolytic zinc production. The metal zinc is adsorbed on the cathode aluminum plate by electrolysis, and then the metal zinc flakes on both sides of the cathode aluminum plate are peeled off through a complete set of automatic zinc stripping equipment, and the zinc flakes are melted, cast and packaged to make zinc ingots. The stripped cathode aluminum plate is returned to the tank again for cyclic electrolytic adsorption of metal zinc. [0003] Before the cathode aluminum plate is put into the electrolytic cell, it needs to be brushed to clean the residual zinc slag on the surface of the aluminum plat...

AI Technical Summary

Problems solved by technology

[0010] ① The opening of the brush wheel cannot be adjusted, the clamping force cannot be adjusted, and it cannot adapt well to the situation where the residual zinc slag on the cathode plate surface changes due to process changes

If the clamping force is too small or the opening of the brush wheel is too large, the cathode plate surface will not be cleaned cleanly, and the composition of the electrolyte will be affected after returning to the tank.

Excessive clamping force or too small opening of the brush wheel will cause severe wear of the brush wheel and cathode aluminum plate, increase equipment wear and consumption, and increase enterprise costs

[0011] ② The operation process is cumbersome and time-consuming, which does not meet the current domestic requirements for efficient production of zinc stripping cycle

[0012] ③Constrained by the structure, the hoisting components in the brushing process drive the cathode plate down, which is mutually exclusive with the direction of rotation of the stick brush, and there is a risk of falling off the plate, and at the same time, the wear of the stick brush is accelerated

[0017] ① In this workflow, the brushing cycle time is about 10-12 seconds, which cannot meet the existing productivity requirements of zinc stripping

[0018] ②The motor belt hoisting system has a large amount of wear on the belt, and the belt needs to be replaced frequently, which brings inconvenience to equipment maintenance

[0023] ①The plate-lifting scrubbing unit must wait for the cathode plate to be put back into the transmission chain before proceeding to the next step, which takes a long time to brush the plate;

[0024] ②This patent adopts the form of dry brush, and the scrubbing effect is not as ideal as that of wet brush
