Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a preparation method of modified bentonite, which can solve the problem that the traditional stirring method is mostly single-direction rotary stirring. Because the concentration of the soil suspension is relatively large, it is difficult to stir quickly and evenly with a single rotary stirring. At the same time, because the bottom of the mixing drum is stirred less vigorously, more solid particles are often deposited at the bottom of the drum, resulting in problems such as uneven mixing.

Abstract

The invention provides a preparation method of modified bentonite. The operation is completed by the cooperation of the stirring frame, the stirring device, the fixed frame, the linkage device and the stirring device. Due to the high concentration of the soil suspension, it is difficult to stir quickly and evenly with a single rotary agitator. At the same time, because the bottom of the mixing drum is stirred less vigorously, more solid particles are often deposited at the bottom of the drum, resulting in uneven stirring and other problems. .

Description

technical field [0001] The invention relates to the technical field of bentonite, in particular to a preparation method of modified bentonite. Background technique [0002] Bentonite has good expansibility and is widely used in chemical industry, petroleum, food, transportation, medicine, papermaking, energy, military industry, environmental protection and other industries, and is called "universal material". In order to meet the needs of certain industries, especially wastewater treatment, and improve the use efficiency of bentonite, it is very necessary to modify bentonite. [0003] In the preparation process of modified bentonite, it is necessary to mix and stir the pyridine solution and the soil suspension. The traditional stirring method is mostly single-direction rotary stirring. Due to the high concentration of the soil suspension, it is difficult to stir quickly and evenly with a single rotary stirring At the same time, because the bottom of the mixing drum is stirr...
