Problems solved by technology

Because the production of copper strips is continuous, the cleaning process of copper strips is continuous, and the acid solution is usually used repeatedly; as the number of times the acid solution is used increases, the accumulation of oxides in the acid solution increases, and the acid solution is polluted, thus affecting the cleaning effect
And if the acid solution is not recycled, frequent replacement will increase production costs, pollute the environment, and reduce production efficiency

Abstract

The invention discloses an acid liquid purification device for copper strip production and a purification method of copper strip. The acid liquid purification device comprises a filtration tank, wherein a filter element is arranged in the filtration tank, a U-shaped liquid inlet pipe and a U-shaped liquid outlet pipe are arranged at the bottom of the filtration tank, and a sealing blocking plate for covering a connecting port is arranged at the connecting port of the liquid inlet pipe and the filtration tank; the top of the filtration tank is provided with an air inlet connector and an opening part connected to a sealing end closure; the air inlet connector is connected to an air source through an air inlet pipeline; a T-junction is arranged on the air inlet pipeline, a first outlet and a second outlet of the T-junction are connected to the air inlet pipeline, a third outlet of the T-junction is connected to an air outlet pipeline, and a control valve is arranged on the air outlet pipeline. According to the purification method, the acid liquid purification device for copper strip production is used for realizing acid liquid purification; after the acid liquid passes through the acid liquid purification device, the acid liquid can be recycled while the cleaning effect of the acid liquid is ensured, and the cost can be greatly reduced.

Description

technical field [0001] The invention relates to the field of copper strip production, in particular to an acid liquid purification device for copper strip production and a purification method thereof. Background technique [0002] In the copper strip production process, sulfuric acid forms an acid solution after a certain proportion, which is often used to clean the oxides on the surface of the copper strip to meet the requirements for the surface finish of the copper strip. Because the production of copper strip is carried out continuously, the cleaning process of copper strip is carried out continuously, and the acid solution is usually used repeatedly; as the number of times the acid solution is used increases, the accumulation of oxides in the acid solution increases, and the acid solution is polluted, thus affecting the cleaning effect. And if the acid solution is not recycled, frequent replacement will increase production costs, pollute the environment, and reduce prod...
