Device and method for stripping electrolytic manganese on cathode plate

Abstract

The invention provides a device for stripping electrolytic manganese on a cathode plate. The device comprises a rack and a stripping component which is vertically supported on the rack; the strippingcomponent comprises multiple rolling shafts which are vertically arranged on the rack and are in rotatable connection with the rack; the multiple rolling shafts are arranged in two rows at intervals in a direction of the rack from the input end to the output end and are sequentially divided into a rough stripping section and a fine stripping section in the direction; a rolling gap, through which the cathode plate passes by subjecting to rolling, is formed between the two rows of rolling shafts; and rotation directions of the two rows of rolling shafts are opposite. The invention further provides a method for stripping the electrolytic manganese on the cathode plate; and in the method, the cathode plate deforms to cause the electrolytic manganese to completely fall off through a procedure of transverse stripping, longitudinal stripping and then transverse stripping. For the device and the method provided by the invention, by arranging the rough stripping section and the fine stripping section to enable a hard and brittle metal manganese layer attached to the surface of the cathode plate to break and fall under the effect of bending force, so that the stripping effect is good, the quality of a product is high, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of metallurgical machinery, in particular to a device and method for stripping electrolytic manganese from a cathode plate. Background technique [0002] There are more than 210 manganese production enterprises in my country, with a total production capacity of more than 4 million tons per year, mainly small and medium-sized enterprises, mainly concentrated in the border areas of Hunan, Guizhou and Chongqing and the border areas of Guangxi and Yunnan; the process of manganese is: compounding (leaching), purification, electrolysis and electrolytic manganese post-treatment. Electrolytic manganese post-treatment refers to a series of operations for electrolytic post-treatment of electrolytic manganese metal products, including passivation, desulfurization, drying, stripping, packaging and cathode plate treatment. At present, these processes are basically mechanized, but their mechanical properties and use effects...

Problems solved by technology

[0004] The invention discloses a device for stripping electrolytic manganese on the cathode plate. In combination with the characteristics of the cathode plate and the metal manganese product attached to its surface, two rows of rollers with opposite rotation directions are arranged, specifically by setting the rough stripping section and The fine stripping section makes the hard and brittle metal manganese layer attached to the surface of the cathode plate break and fall off under the action of the bending force to achieve the effect of stripping, and utilizes the elasticity and automatic recovery function of the cathode plate itself to make the stripping process The generated deformation automatically returns to the original state, which solves the technical problems of low service life of the cathode plate and poor peeling effect caused by the knocking and peeling method in the prior art
