Preparation method of anhydrous magnesium sulfate drying agent

Abstract

The invention relates to a preparation method of an anhydrous magnesium sulfate drying agent. The preparation method comprises a workbench, a first processing device and a second processing device, the upper end of the workbench is fixedly provided with the first processing device, and the upper end of the first processing device is fixedly provided with the second processing device; the first processing device comprises a cylindrical plate, a vibration motor, a screening frame, a first motor, a rotating column, a grinding disc, a first grinding ring, a second grinding ring, a screening disc and a discharging pipe, the first processing device is matched with the second processing device, anhydrous magnesium sulfate blocks are minced, and minced anhydrous magnesium sulfate particles are screened and ground; and finally, the ground anhydrous magnesium sulfate powder is screened and collected, so that the quality of the anhydrous magnesium sulfate powder is uniform, meanwhile, the production efficiency of equipment is improved, the abrasion loss of grinding parts during grinding of anhydrous magnesium sulfate particles is reduced through the first processing device, and the surface stress of the grinding parts is uniform.

Description

technical field [0001] The invention relates to the field of desiccant preparation, in particular to a preparation method of anhydrous magnesium sulfate desiccant. Background technique [0002] Anhydrous magnesium sulfate is an inorganic compound with the molecular formula MgSO 4 , colorless orthorhombic crystal, soluble in water, ethanol, glycerin, insoluble in acetone, used in pharmaceutical and printing and dyeing industries, can also be used as desiccant, feed, fertilizer or compound fertilizer, and is also a raw material for the production of magnesium oxide, anhydrous Magnesium sulfate is ground into powder and then passed through a granulator to make desiccant particles with different shapes and volumes according to needs. [0003] In the process of preparing the anhydrous magnesium sulfate desiccant, due to the different shapes of the desiccant, it is necessary to grind the anhydrous magnesium sulfate block into powder for easy processing. In the actual operation pr...

AI Technical Summary

Problems solved by technology

[0004] (1) When the traditional anhydrous magnesium sulfate desiccant preparation equipment grinds anhydrous magnesium sulfate, it is generally directly ground, which can easily lead to low processing efficiency of the equipment, and the quality of the processed anhydrous magnesium sulfate powder lower

[0005] (2) When the traditional anhydrous magnesium sulfate desiccant preparation equipment grinds anhydrous magnesium sulfate, the grinding parts are extremely vulnerable to wear, which requires frequent replacement, which affects the normal use of the equipment
