Pretreatment device for purifying high-purity aluminum oxide and treatment method

Abstract

The invention discloses a pretreatment device for purifying high-purity aluminum oxide and a treatment method, and particularly relates to the technical field of aluminum oxide purification. Through the transmission effect of a first gear in a stirring device, a second gear and a third gear can be controlled to rotate in opposite directions, and a first stirring frame and a second stirring frame can rotate in a staggered mode, and the purpose of bidirectional stirring is achieved. The first stirring frame and the second stirring frame can move up and down in a reciprocating mode again through the transmission control effect of an elastic transmission structure, and then solution mixing uniformity is guaranteed through staggered rotation and up-and-down movement. Meanwhile, a solution can be drained to the upper part for mixing treatment again through the cooperation of a cam and a drainage assembly, and meanwhile, uniform heating of the solution can be ensured in the drainage process, so that the device can achieve a better treatment effect through the mode, and the production and processing requirements are met.

Description

technical field [0001] The invention relates to the technical field of alumina purification, more specifically, the invention relates to a pretreatment device and a treatment method for purifying high-purity alumina. Background technique [0002] In the process of purifying high-purity alumina, it is often necessary to use a pretreatment device to mix aluminum hydroxide and caustic soda to facilitate the reaction of the two to generate sodium metaaluminate solution. The pretreatment mixing device in the prior art Generally, it is simply combined by a mixing cylinder, a mixing rod and a mixing driving device, and it takes a lot of time to mix aluminum hydroxide and caustic soda through the above-mentioned device, and the stirring effect is not good. The application number is The Chinese invention of CN201711041987.1 discloses a hot-melt glue mixing equipment for the production of natural gas aluminum-plastic composite pipes. It uses a lifting device to make the hot-melt glue ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pretreatment device and a treatment method for purifying high-purity alumina. The technical problem to be solved by the present invention is: the pretreatment mixing device in the prior art passes through the lifting device The hot melt adhesive can be stirred more evenly, thus achieving the effect of saving time and better stirring effect, but in actual use, the rotation of the mixing rod is easy to drive the solution
