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 ...

AI Technical Summary

Problems solved by technology

Its disadvantages are: using industrial water pipes to directly wash the manganese plate, the labor intensity of the employees is high, the working hours are long, the impurities attached to the electrolytic manganese plate are not easy to clean thoroughly, and it is easy to cause high sulfur content in the product, or the cleaning liquid If it is not clean, it will affect the quality of the product; and it is necessary to manually push the electrolytic manganese plate into the oven for drying. Since the temperature in the oven cannot be adjusted, it is easy to cause high surface temperature and blackening, resulting in the grade rate of the C-grade product. Low, only about 12.20%. When using manual operation to clean the pole plate, when pushing and cleaning the pole plate, due to the vibration generated by the pushing and uneven cleaning force, it is easy to cause a large number of electrolytic manganese sheets to fall off, thus affecting the product output.

Its disadvantages are: it can only clean and dry the electrolytic manganese pole plate after it has been released, and the stripped electrolytic manganese pole plate still needs to be cleaned manually, which increases the labor intensity of employees and the cleaning quality is low. At the same time, nitrogen and deoxygenated tap water need to be used , the cleaning cost is high, and the operation cycle is long. Although the electrolytic manganese plate can be passivated after the plate is released, the operability is not strong in the actual production process.
