Abstract

A negative plate 1 for electrolytic copper powder is provided with a short lug and a long lug and is characterized in that the long lug is of a two-step type and the lateral side of the long lug is connected with a conductive copper bar through a conductive block. The long lug of the negative plate is designed to be of the two-step type and the lateral side of the long lug is connected with the conductive copper bar through the conductive block so that conductive over-current area is enlarged and conductive efficiency is improved.

Description

A cathode plate for electrolytic copper powder

technical field

The utility model relates to a cathode plate, in particular to a cathode plate for electrolytic copper powder.

Background technique

In the copper powder electrolytic cell, the cathode plate and the anode plate are arranged in a staggered manner, and a certain distance is maintained according to the process requirements. The existing cathode plate has two hanging lugs, one long and one short. The end of the long hanging lug is directly in contact with the conductive copper bar for conducting electricity, and the end of the short hanging lug is not in contact with the conductive copper bar, so it is not conductive. Since the cathode plate is usually relatively thin (4-6mm), and the distance between the two hanging lugs is determined by the width of the electrolytic tank, the conductive area is determined by the thickness of the cathode plate and the length of the hanging lugs. Because the cathode plate is relatively thin, the contact cross-sectional area of the hanging lug and the conductive copper bar is small, which causes the hanging lug to become hot during the electrolysis process and reduces the conduction efficiency.

Utility model content

The purpose of this utility model is to provide a cathode plate for electrolytic copper powder with hanging lugs that are not easily heated.

The purpose of this utility model is achieved in this way, a cathode plate for electrolytic copper powder, including short hanging lugs and long hanging lugs, characterized in that: the long hanging lugs are two-stage stepped and the side of the end part passes through it. The matching conductive block is connected to the conductive copper bar.

The long hanging lug is provided with two connection holes and is connected with the conductive block through bolts.

The utility model has the following beneficial effects. In the utility model, the long lug of the cathode plate is designed as a two-stage step type, and its side is connected with a conductive block and a conductive copper bar adapted to it, which increases the conductive overcurrent area and improves the conduction efficiency.
