Recycling and reusing device for preparing lithium hexafluorophosphate and mounting method of recycling and reusing device

Abstract

The invention discloses a recycling and reusing device for preparing lithium hexafluorophosphate and a mounting method of the recycling and reusing device; a mother liquor storage tank comprises a first tank body, a second tank body and an mounting support, the first tank body comprises a bottom plate, an inclined plate, a surrounding plate and a top plate, the mounting support is provided with a supporting frame, and the supporting frame extends into a supporting space. The method comprises the steps: a, mounting the mounting support; b, adjusting the inclination angle of the supporting frame; c, welding the inclined plate and the bottom plate; d, supporting the inclined plate; e, mounting to obtain the first tank body; f, mounting a pressing plate; g, rotating by 180 degrees, and mounting a material conveying pipe; h, welding a positioning support; i, mounting to obtain the second tank body; j, resetting and integrally taking out the mother liquor storage tank; and k, connecting the mother liquor storage tank with a lithium fluoride dissolving tank. According to the invention, the impact force of mother liquor on the first tank body is transmitted to the mounting support through the supporting frame, and the first tank body buffers the entering mother liquor, so that the structures of the first tank body and the second tank body are not easy to damage.

Description

technical field [0001] The invention belongs to the technical field of lithium hexafluorophosphate preparation, and in particular relates to a recovery and reuse device for preparing lithium hexafluorophosphate and an installation method thereof. Background technique [0002] Lithium hexafluorophosphate is currently the most widely used electrolyte salt in commercial lithium-ion batteries. With the rapid development of the electronics industry and the continuous expansion of the new energy field in the future, the demand for high-performance batteries is increasing, and the market demand for lithium hexafluorophosphate will show a trend of rapid increase. [0003] The Chinese patent disclosed an invention patent named a continuous production system for lithium hexafluorophosphate (application number: CN201911254953.X) on 2019.12.10, in which the output material of the microchannel reactor enters the gas-liquid separator, and the gas-liquid separator separates out The liquid...
