Abstract

The invention discloses a filtering device for a lithium sulfate concentrate for lithium mica production. The filtering device comprises a first kettle body and a first liquid outlet pipe. The upper end of the first kettle body is provided with a liquid inlet. The lower end of a filter plate frame is provided with a first filter net. The first liquid outlet pipe is disposed on the right side surface of the first kettle body. The first liquid outlet pipe passes through a second kettle body and is connected to a first feeding pipe. The fixed upper end of the second kettle body is provided with areagent cartridge. The middle of a connection rod is provided with a flow passage. The lower end of a liquid discharge tray is provided with a reaction tank. The left end of the reaction tank passesthrough the second kettle body and is connected to a first motor. The outer side of the right end of the second kettle body is connected to a second liquid outlet pipe. The filtering device can control the use amount of sodium carbonate, guarantee the reaction stability and prevent individual stirring and washing, has a small occupied area, realizes a low cost and has good centrifugal filtration effects.

Description

technical field [0001] The invention relates to the technical field related to lepidolite, in particular to a filter device for lithium sulfate concentrate for lepidolite production. Background technique [0002] In sulfuric acid ore extraction of lithium, the ore generally undergoes grinding, transition roasting, acidification, leaching, purification and filtration to obtain a relatively pure dilute lithium sulfate solution. The dilute lithium sulfate solution is mainly used for the subsequent production of lithium chloride and lithium hydroxide. Or lithium carbonate and other products, some companies have carried out unified treatment in order to separate the mixed liquid. Generally, after filtering by the filter equipment, the mixed liquid still remains in the equipment, and some solid and liquid mixed liquids are accelerated by centrifugation. good. [0003] The filtration equipment of lithium sulfate concentrate for general lepidolite production cannot control the addi...
