Modified bentonite preparation method

Abstract

The invention relates to a modified bentonite preparation method, the modified bentonite preparation method adopts the following modified bentonite preparation device, the modified bentonite preparation device comprises a stirring cylinder, a storage ring, a base, a sieve plate, a stirring motor, a stirring rod and a sliding mechanism; the preparation method adopting the modified bentonite preparation device comprises the following steps: S1, bentonite is subjected to stirring pretreatment; s2, bentonite is stirred; s3, sundries fall off; s4, bentonite collection is performed. The following problems can be solved: when the bentonite is stirred in the prior art, the stirring time of the bentonite is long, a large number of impurities in the bentonite are left in bentonite suspension liquiddue to incomplete stirring of the bentonite, the preparation effect of the bentonite is poor, and the preparation purity is low; and when the bentonite is stirred, impurities can be accumulated at thebottom of the stirring cylinder, and part of the impurities can be turned up again to reach bentonite suspension liquid along with stirring.

Description

technical field [0001] The invention relates to the technical field of bentonite preparation, in particular to a preparation method of modified bentonite. Background technique [0002] Bentonite is a non-metallic mineral whose main mineral component is montmorillonite. Bentonite can be compact block or loose soil. It feels slippery when rubbed with fingers. After adding water, the volume expands several times to 20-30 times. It is suspended in water, and it is paste when water is little. After the purification of bentonite, the surface is usually treated by physical, chemical, mechanical and other methods, and the physical and chemical properties of the mineral surface are purposely changed according to the application needs, so as to meet the application in different technologies and fields, and then improve The nature, function and use value of bentonite. [0003] The bentonite purification process first needs to be crushed into a powder with a suitable particle size, an...

AI Technical Summary

Problems solved by technology

[0004] 1. It takes a long time for the bentonite to stir, and the bentonite will cause a large amount of impurities in the bentonite to remain in the suspension of the bentonite due to incomplete stirring of the bentonite, resulting in poor preparation effect of bentonite and low preparation purity;

[0005] 2. When the bentonite is stirred, the sundries will accumulate at the bottom of the mixing tank, and some of the sundries will be re-turned into the bentonite suspension as the stirring progresses, resulting in the bentonite solution needing multiple purification operations
