Description

Technical Field

[0002] Lithium and lithium salts have been expanded from traditional application fields such as glass ceramics, electrolytic aluminum, grease, refrigeration, etc. to high-tech fields such as aluminum-lithium alloys, lithium batteries, and nuclear fusion. Especially in the field of new energy technology, lithium batteries are widely used. The methods for extracting lithium from lithium minerals mainly include sulfate method, chloride method, limestone method, sulfuric acid method, and gas-solid reaction method. When preparing lithium carbonate by sulfuric acid method, wastewater will be generated. If the wastewater is directly discharged into the sewer or river, it will cause serious damage to the ecological environment of the surrounding environment. In the prior art, the wastewater generated during the production of lithium carbonate will be recycled, and harmful substances in the wastewater can be removed through chemical reaction and filtration. It is conducive to achieving an energy-saving, environmentally friendly, and environmentally friendly industrial environment. When filtering the wastewater after the reaction, impurities are easily accumulated on one side of the filter plate, and it needs to be cleaned regularly to keep the filter plate in a good filtering effect.

[0003] The existing technology has the following problems:

This patent can clean the filter plate without disassembling it through the cooperation between the lifting mechanism, the filter plate, the box body, the scraper and the connecting rod.

[0005] However, the above patent still has problems that need to be improved during actual use. The most obvious one is that after repeated use, a gap will be generated between the scraper and the filter plate, thereby affecting the cleaning effect and efficiency of impurities on the surface of the filter plate.

[0006] To this end, we proposed a wastewater recycling device for lithium carbonate production to solve the above-mentioned drawbacks. Utility Model Content
