A zinc electrowinning stripping scrubbing unit and method thereof

Abstract

The invention discloses a zinc electrodeposition stripping and scrubbing unit. The zinc electrodeposition stripping and scrubbing unit comprises an elimination line, a zinc stripping line, a scrubbing line, an auxiliary scrubbing line and a manual zinc stripping line, wherein the elimination line, the zinc stripping line, the scrubbing line and the auxiliary scrubbing line are connected through a negative plate conveying chain I; the auxiliary scrubbing line and the manual zinc stripping line are connected through a negative plate conveying chain II; and the elimination line, the zinc stripping line, the scrubbing line, the auxiliary scrubbing line and the manual zinc stripping line are sequentially arranged side by side along the negative plate conveying chain I and the negative plate conveying chain II. The invention also discloses a process method for the zinc electrodeposition stripping and scrubbing unit. According to the zinc electrodeposition stripping and scrubbing unit, the manual zinc stripping line and the auxiliary scrubbing line are provided for negative plates on which automatic stripping is unsuccessfully conducted or mechanical stripping cannot be performed, and when mechanical zinc stripping fails, manual zinc stripping can be performed, the negative plates are conveyed to the auxiliary scrubbing line for scrubbing after stripping, and plates can be supplemented in real time to realize effective running of the unit.

Description

technical field [0001] The invention relates to the technical field of zinc smelting, and more specifically, to a zinc electrowinning stripping scrubbing unit and a method thereof. Background technique [0002] In the field of hydrometallurgy in the non-ferrous smelting industry, non-ferrous metals are obtained by first attaching the non-ferrous metals to the surface of the cathode plate to form a metal layer through electrolysis and electrowinning, and then peeling off the metal layer from the surface of the cathode plate. . According to the current production process, a series of processes are completed through pre-stripping, stripping and cathode plate scrubbing in sequence. In addition, there are two methods for stripping the non-ferrous metal layer from the cathode plate, one is manual stripping, and the other is machine. peel off. The machine stripping is faster and more efficient than manual stripping, but machine failures may occur during the machine stripping proc...

Problems solved by technology

In this way, the stop in the middle of the rise and fall and the opening and closing of the stripping knife increase the working time of the entire stripping process, slow down the stripping speed, reduce the work efficiency, increase the number of starts of the motor and reduce the service life, resulting in production cost increase

[0006] The brushing unit adopts nylon roller brushes, the scrubbing effect is not good, and the tensioning method adopted by the roller brushes is unreasonable, resulting in a short service life of the belt driving the roller brushes, and the brushing tension cannot be adjusted; the two brush rollers have no synchronous device, and the rollers When the brush is closed, the vibration and impact are relatively large, and the bearing needs to be replaced frequently

[0007] The process layout is single, without considering the actual situation of production, without the function of automatic stripping and patching, and without manual participation in the design
