Residual acid filter device for plate acid leaching

Abstract

The invention provides a residual acid filter unit of counter electrode acid leaching. Acid which is leached is collected and stored by an acid leaching collection box; the acid leaching collection box is internally provided with a filter screen for firstly filtering out larger particulate matters; lead powder is then filtered out through deep filtration by at least three filter flasks which are provided with first non-woven filter layers and second non-woven filter layers; acid which is filtered enters into an acid collection box and can be reused; the filter flasks are connected with acid inlet pipes and acid outlet pipes through connection blocks, and in this way, the filter flasks can be disassembled easily, so as to remove the lead powder which is filtered out; the at least three filter flasks are arranged, thus, according to practical situation, a certain number of filter flasks can be selectively opened for filtration; the acid collection box is internally provided with an agitating blade for a person to operate and observe turbid and limpid statuses of the acid in the acid collection box. The residual acid filter unit of counter electrode acid leaching is simple in structure and easy in operation, and can be favorably applicable to filtration of the acid leaching in a workshop.

Description

technical field [0001] The invention relates to the field of residual acid treatment of polar plate acid leaching, in particular to a residual acid filtering device for polar plate leaching acid. Background technique [0002] Our company mainly produces various types of batteries. The batteries will use plates in the production process, and the plates must be treated with acid during the production process. The acid that has been soaked through the plates needs to be recycled and reused, but Contains large particles and some lead powder impurities, which will affect the reuse, so it must be filtered. Currently, the leached acid is generally filtered by a filter and then pressed to use the lead powder and acid separately, but the filter press is too large. The cost is too high and the operation in the workshop is not used, so it is necessary to design a residual acid filter device suitable for the workshop and put it into production, so it is very necessary to solve this prob...
