Manganese dioxide compound stone powder slurry system and its control method

Abstract

The invention discloses a manganese dioxide compound stone slurrying system and a control method thereof. The manganese dioxide compound stone slurrying system comprises a silo; a tank car pumping pipeline and a dust remover are arranged at an inlet in the upper part of the silo; a star feeder is arranged at an outlet in the lower part of the silo, a slurrying tank is mounted at an outlet in the bottom of the star feeder, a stirring motor is arranged in the slurrying tank, a production sewage pipe is connected with the inlet end of the slurrying tank, a control valve is arranged at the outletend of the slurrying tank, a plurality of compounding tanks are connected with the outlet end of the slurrying tank through slurry material distribution tubes, the slurry material distribution tubes of the plurality of compounding tanks are communicated with one another through grading chutes, and the adjacent grading chutes are connected with each other through a grading chute control pipe. The manganese dioxide compound stone slurrying system and the control method thereof disclosed by the invention have the benefits that a stone powder in a car is fed into the stone powder silo by using compressed air and is supplied with the star feeder; production sewage is used as a slurry liquid; a slurrying material is supplied to the compounding tanks through the grading chutes, so that almost nodust is produced, an operating environment is greatly improved, the environmental pollution is effectively avoided, and the material and labor costs are reduced.

Description

technical field [0001] The invention relates to a manganese dioxide compound neutralization system and a control method thereof, in particular to a manganese dioxide compound stone powder slurry system and a control method thereof. Background technique [0002] The manganese dioxide compounding process includes steps such as feeding, acid reaction, neutralization, impurity removal, material transfer and pressure filtration. In the neutralization process, most enterprises use lime powder to slurry and then add it to the compounding tank for reaction, or manually use a bucket truck Pulled stone powder is put into the chemical tank for reaction. Because the price of lime powder is more than four times that of stone powder, the production cost is high, and it is gradually replaced by stone powder. However, the traditional method of throwing stone powder by manual bucket truck has several defects. First, the operating environment is harsh, the dust is large, and the occupational ...

Problems solved by technology

However, the traditional method of throwing stone powder by manual bucket truck has several defects. First, the operating environment is harsh, the dust is large, and the occupational disease hazards to the operator are great; the labor intensity is high, and all operations are performed manually; When evolving the combined tank, the speed is slow and the efficiency is low, which affects the neutralization time. The carbon dioxide produced by the violent reaction will push the solution out of the combined tank, causing the tank to leak and pollute the environment.

Since artificial stone powder is a dry powder feed, when the dry powder contacts with the acidic chemical solution, the stone powder is easy to agglomerate and form a package, the reaction is not complete, and the consumption of stone powder is large.
