Method for washing electrolytic manganese polar plate

Abstract

The invention provides a method for washing an electrolytic manganese polar plate. The method comprises the following steps: putting a passivated electrolytic manganese polar plate into an ultrasonic washing groove; putting the electrolytic manganese polar plate into a water washing groove to be washed by clean water; conveying the electrolytic manganese polar plate into an air drying groove to be aired; drying in a drying oven and blowing in an air blowing groove by strong air; conveying the electrolytic manganese polar plate into a stripping region to be finished; putting the stripped electrolytic manganese polar plate into an anode liquid immersion groove to be immersed and then putting into a plate washing groove to be activated by a plate washing solution; conveying the electrolytic manganese polar plate into the ultrasonic washing groove to be washed by the clean water and putting into the water washing groove to be washed by the clean water; and finally, conveying the electrolytic manganese polar plate into the air drying groove to be aired by the strong air and conveying the electrolytic manganese polar plate into a plate reserving region for later use. The method has the advantages that the method is simple and easy to operate; impurities on the surfaces of the electrolytic manganese polar plate and the stripped polar plate are removed effectively and the washing effect is good; the electrolytic manganese polar plate does not need to be washed by a lot of industrial water to realize water saving, energy conservation and environmental protection; the grade rate of a product is also improved and the grade rate of a C-grade product can be up to 60%-63%; the washing effect is good, the falling of an electrolytic manganese sheet is reduced to the greatest extent and the yield of the product is improved.

Description

technical field

[0001] The invention relates to a method for cleaning electrolytic manganese pole plates. Background technique

[0002] Electrolytic manganese metal is an important metallurgical and chemical raw material. In order to improve the quality of electrolytic manganese, it is necessary to clean the electrolytic manganese plate. When cleaning electrolytic manganese plates in my country's electrolytic manganese factories, most of them are manually operated, and the main operation steps are as follows: (1) Washing: Lifting the electrolytic manganese plates after passivation treatment, draining the passivation solution, Put it on the plate car and transport it to the manganese washing area, and then manually wash it with industrial water for more than 20 minutes until the electrolyte, passivation solution and other solutions adhering to the metal manganese surface are washed away. (2) Drying: Send the washed electrolytic manganese plate into the oven for more than 40 ...
