Raw material preparation device for humic acid soil remediation agent

Abstract

The invention relates to the field of soil remediation, in particular to a raw material preparation device for a humic acid soil remediation agent. The technical problem to be solved by the invention is to provide the raw material preparation device for the humic acid soil remediation agent. According to the technical scheme, the raw material preparation device for the humic acid soil remediation agent comprises a crushed material cleaning and filtering system and the like; the crushed material cleaning and filtering system is connected with a stirring system; and the stirring system is connected with a centrifugal precipitation system. According to the invention, the surface of the weathered coal is washed by combining the characteristic that a large amount of dust powder adsorbates exist on the outer surface of the weathered coal; and meanwhile, a direct impregnation method is changed, an alkalinized coal mixture is used for improving the solubility of the coal, then centrifugation is performed to obtain a filtrate, and finally the mixed solution is acidified again, so that a high-quality coal humic acid substrate is obtained; the conversion rate of converting the weathered coal into the humic acid is improved.

Description

Technical field [0001] The present invention relates to a soil restoration field, and more particularly to a raw material preparation device for a humic acid soil repair agent. Background technique [0002] The curved acid in the conventional humic acid soil repair agent is mainly from coal matter, such as peat, lignite and weathering coal. [0003] In the prior art, in the production of coal-type humic acid, it is generally obtained by directly mixing of the weathering coal directly to the preparation solution, and then remove the excess waste slag to remove the acid solution, which leads to a large number of waste of weathering coal. And the transformation rate prepared by coal-type humic acid is extremely low; there is still a large amount of dust-clad powder adsorbers in the surface of weathered coal, so that the quality of the coal-type hydrochloric acid is not high, affecting the repair function of soil repair agents; Improve the device of coal-type humic acid conversion. ...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the preparation of coal humic acid in the prior art, the weathered coal is usually directly mixed with the preparation solution, soaked for a period of time, and then the excess waste residue is removed, and then the acid solution is added for precipitation. A lot of waste, and the conversion rate of coal humic acid preparation is extremely low; there are a lot of dust powder adsorbates on the outer surface of weathered coal, which makes the quality of coal humic acid produced is not high, which affects the repair function of soil remediation agent; urgently needed The shortcoming of a device for improving the conversion rate of humic acid in coal, the technical problem of the present invention is: to provide a raw material preparation device for humic acid soil remediation agent
