Drum screening machine for screening out nickel residual anodes

Abstract

A drum screening machine for screening out nickel residual anodes is mainly composed of a tank (1), a drum (2), a gear reducer (3), a towing wheel (4), a chain (5), a feeding hopper (6), an oversize material discharge hopper (7), an undersize material discharge hopper (8) and a base (9). The drum screening machine for screening out the nickel residual anodes is characterized in that all the components are linked in a mechanical, screwed and welding manner, the drum driving manner of the drum screening machine is sprocket driving, and a driving device is composed of the gear reducer (3), the chain (5) and a chain fixing pin (11). Anode mud is screened out of screen holes in the drum and discharged out of the undersize material discharge hopper (8), and the nickel residual anodes are discharged out of the oversize material discharge hopper (7) at the terminal end of the drum as undersize materials. In the rotating process of the drum, six sets of lifting boards lift the nickel residual anodes alternately, so that the material stacking probability is fully decreased, and the phenomenon of discharge blocking caused by interwinding of copper wires on the nickel residual anodes is avoided; and due to the fact that the two corners of each lifting board are made to be round, the situation that copper wires are wound around and stacked on the lifting boards when hung on the lifting boards is avoided.

Description

technical field [0001] A drum sieving machine specially designed for screening nickel electrolysis process product - nickel anode, which can remove the anode slime on the surface of nickel anode by sieving. In addition, this equipment is also suitable for screening other anode sludge with attachments Large plate-like material, to separate the material from the attachment. Background technique [0002] Nickel anode is the anode product of the nickel electrolysis production process. After the nickel anode plate is electrolyzed, the remaining product is called nickel anode. The nickel residue is plate-shaped, with a layer of anode slime attached to both surfaces, and a copper ear wire for hanging is inserted into the head of the nickel residue. [0003] Description of properties of nickel anode residue: [0004] Anode mud is attached to both sides of the residual plate, and two U-shaped copper wires are inserted into the head of each residual plate. The thickness of anode sl...

AI Technical Summary

Problems solved by technology

[0006] Since the nickel butt plate is plate-shaped, the single-sided area is 400-1200cm 2 , with anode slime attached on both sides, the thickness of the anode slime layer is 4-6mm, and the moisture content is 10-25%. It can be sieved by manual sieve, which has high labor intensity, low sieving efficiency and poor sieving quality
