Sprinkled acid recycling device and pasting equipment of battery plates

Abstract

The invention discloses a sprinkled acid recycling device and pasting equipment of battery plates. The sprinkled acid recycling device comprises a filter tank, a recycling settling tank and a filter screen, wherein the filter tank and the recycling settling tank are mutually communicated, an acid inlet is arranged at the upper part of the filter tank, an acid outlet is arranged at the upper or middle part of the recycling settling tank, and the filter screen is laid in the filter tank and positioned below the acid inlet. By the sprinkled acid recycling device, firstly lead plaster and acid liquor in the sprinkled acid are separated by the filter screen in the filter tank, and the filtered and settled acid liquor can be obtained from the recycling settling tank. The acid liquor can be directly lead to the acid sprinkling station of a pasting machine for sprinkling the pole plate for onsite recycling. The treatment mode is simple and quick and obviously improves the process efficiency, and lead plaster is separated from the sprinkled acid as much as possible in the filtered and settled acid liquor, so that the treatment is more complete, the environmental performance is good, and the phenomenon that a recycling pump and an acid sprinkling port are blocked during recycling is avoided.

Description

technical field [0001] The invention relates to the field of accumulators, in particular to an acid leaching recycling device and paste coating equipment for accumulator polar plates. Background technique [0002] As the core component of the lead-acid battery, the plate plays a decisive role in the performance of the lead-acid battery. Therefore, the production of the plate is a key link in the battery manufacturing process, and its quality requirements are also extremely strict. According to the battery of different purposes, the plates are also different. According to the structure of the plates, there are paste type, tube type and forming type. [0003] At present, paste-coated plates are commonly used in the lead-acid battery industry. The process of paste-coating the plates is the process of plate-coating. In order to prevent cracks on the surface of the plates from greatly affecting the quality of the plates, usually A method of acid leaching is adopted to avoid the ...
