Lithium porcelain stone tailings defluorination device based on solvent flotation method

Abstract

The invention discloses a lithium porcelain stone tailings defluorination device based on a solvent flotation method, which relates to the technical field of lithium porcelain stone processing. The lithium porcelain stone tailings defluorination device based on a solvent flotation method comprises a body, a driving motor, an accelerating mechanism, a one-way valve, a feeding mechanism, a rotatingmotor, a gear, a cover plate, a port, a connecting rod and a collecting mechanism, wherein the driving motor is fixedly installed in the middle part of the bottom of the body, and the output shaft ofthe driving motor penetrates the middle part of the bottom of the body and is fixedly connected with the middle part of the bottom of the accelerating mechanism. The lithium porcelain stone tailings defluorination device based on a solvent flotation method uses a rotating spiral plate surface to drive the boric acid in the falling process to rotate spirally upwards and float, thus achieving the effect of promoting the full reaction between the boric acid and the solvent. At the same time, when the accelerating mechanism rotates counterclockwise, the solvent in the body also rotates counterclockwise, and the collecting mechanism cooperates with the collecting mechanism to effectively collect the flotation substance of the liquid surface.

Description

technical field [0001] The invention relates to the technical field of lithium china stone processing, in particular to a lithium china stone tailings defluorination equipment based on a solvent flotation method. Background technique [0002] In the production process of glass-ceramic plates using lithotine tailings, it is necessary to defluorinate the lithotine tailings, and the defluorination of tailings can be defluorinated by wet phosphoric acid. In the deep defluorination technology, it can be specifically It covers cooling crystallization method, vacuum concentration method, steam stripping method and solvent flotation method. The reaction process of solvent flotation method is roughly as follows: adding boric acid-collector-organic solvent-surfactant. [0003] The invention patent with the publication number CN 104555961 A discloses a method for defluorination and desulfurization of tailings, which includes the following points: (1) Use phosphate ore beneficiation tai...

AI Technical Summary

Problems solved by technology

[0004] In this defluorination method, there is no relevant auxiliary mechanical structure in the reaction process, and the defluorination process is mainly completed through the autonomous reaction of the solvent. This method takes a long time to react, and it cannot guarantee whether the additive will fully react with the solvent, and there is a waste of resources and reactions. The disadvantage of longer time, which affects the overall processing progress of the glass-ceramic plate
