AI Technical Summary

Technical Problem

During the lead electrolytic refining process, the temperature non-uniformity of the electrolyte leads to a decrease in electrolysis efficiency, affecting the lead electrolytic refining effect.

Method used

A lead electrolytic refining device with circulating electrolyte was designed. The electrolyte temperature was automatically adjusted by thermostatic components and flow control components to ensure that the temperature difference between different areas in the tank was reduced. Multi-channel heat exchange plates and adjustment units were used to achieve automatic regulation of the coolant flow.

Benefits of technology

It effectively improves the efficiency of lead electrolytic refining, ensures consistent temperature in all areas of the tank, and improves the recycling efficiency of the electrolyte and the lead refining effect.

Abstract

The invention provides a lead electrolytic refining device with a recyclable electrolyte, and belongs to the technical field of electrolyte circulation. The device comprises: a tank body, the top of which is provided with a working tank; an electrode sheet; the constant-temperature assembly is arranged on the outer side of the tank body and comprises a liquid inlet pipe, heat exchange plates and a liquid outlet pipe, the liquid inlet pipe and the liquid outlet pipe are arranged on the left side and the right side of the tank body respectively, the two heat exchange plates are attached to the front side and the rear side of the tank body respectively, and the two sides of the heat exchange plates communicate with the liquid inlet pipe and the liquid outlet pipe through connecting pipes respectively; the flow adjusting assembly comprises a sleeve, a first expansion air bag and a piston, the sleeve is connected to the side, close to the groove body, of the liquid inlet pipe, the side, away from the liquid inlet pipe, of the sleeve penetrates through the groove body and extends into the working groove, the side, located in the working groove, of the sleeve is connected with the first expansion air bag, and the side, away from the working groove, of the first expansion air bag is connected with the piston. The piston is provided with a groove and a liquid discharge hole. Through the flow adjusting assembly, the flow of the cooling liquid can be adjusted, and therefore the lead electrolytic refining effect of the electrolyte is effectively guaranteed.
