[0001] The utility model belongs to the technical field of support mechanisms, and particularly relates to an internal support structure of a new type of cathode roller. Background Art

[0002] A cathode roller is a special device used in the electrolysis process of hydrometallurgy. Generally speaking, it is a conductive roller. It is often used in large electrolytic cells for electrolysis of copper, nickel, zinc, etc., and plays the roles of current conduction, solution stirring and pressing. The cathode roller is composed of multiple hollow tubes, and the inner wall is coated with lead or lead alloy. The internal structure of the cathode roller is not completely solid. It is composed of multiple hollow tubes, and the outer diameter and length of the tubes vary according to different usage requirements, generally ranging from dozens to more than a hundred tubes. Moreover, the hollow tubes have uniform intervals and angular connections, and the whole structure is very precise. Lead or lead alloy is coated on the inner wall of the internal hollow tubes of the cathode roller to improve the conductivity, so as to prevent the current path of the electrolytic cell from jumping from the air to the liquid surface and the electrolytic cell container, causing an explosion of the electrolytic cell.

The titanium cylinder is sleeved outside the conductive steel cylinder. Multiple pairs of contact pieces are fixedly welded on the inner wall of the conductive steel cylinder. There are two sealing end caps, which are respectively fixedly installed at both ends of the titanium cylinder. A plurality of socket joints are integrally formed at one end of the two sealing end caps close to each other. A plurality of support rods are fixedly inserted between the two sealing end caps through the socket joints. A plurality of contact heads are integrally formed at equal intervals in the circumferential direction on the periphery of the conductive web, and bolts are inserted into the contact heads.

[0006] As a preferred technical solution of the utility model, a plurality of contact holes are formed in the inner wall of the titanium cylinder, and a plurality of contacts are integrally formed on the outer arc surface of the conductive steel cylinder corresponding to the contact holes.

[0011] As a preferred technical solution of the present utility model, rubber sealing rings are provided between the two conductive webs and the two ends of the titanium cylinder.

[0012] The beneficial effects achieved by the present utility model are as follows:
