AI Technical Summary

Technical Problem

In existing technologies, powdered reagents are difficult to dilute sufficiently when added to the treatment tank, resulting in reagent waste and poor water treatment effect.

Method used

A chemical dosing device for groundwater remediation is adopted, comprising a treatment tank, a chemical storage container, a stirring assembly, and a drive assembly. Through the lifting and rotating motion of the stirring assembly and the sealing effect of the baffle component, the chemical is added intermittently and slowly and thoroughly stirred and diluted.

Benefits of technology

This method achieves thorough dilution of the reagents, saves on reagent usage, improves groundwater treatment efficiency, and avoids problems such as clogging of the reagent outlet pipe and inaccurate dispensing.

Abstract

The invention relates to a medicament feeding device for groundwater remediation and treatment. The medicament feeding device comprises a treatment tank, a medicament storage container, a necking section, a medicament outlet pipe, a stirring assembly, a first stirring shaft, a material blocking part, a driving assembly, a cylinder, a non-circular ring-shaped track, a cylindrical pin, a spline housing, a spline, a second bevel gear, a first bevel gear and a driving part, through the guiding effect of the non-circular annular track on the cylindrical pin, the first stirring shaft does lifting and rotating motion, when the material blocking component ascends to be separated from the medicine outlet pipe, the medicine in the medicine storage container falls into the treatment tank, the medicine outlet pipe is sealed when the material blocking component descends, the medicine does not enter the treatment tank any more, and the treatment effect is good. The lifting and rotating stirring assembly stirs and dilutes the medicament, the medicament is intermittently and slowly added into to-be-treated underground water, and the stirring assembly performs lifting and stirring on the medicament, so that the medicament flows between an upper water layer and a lower water layer, the medicament is fully diluted, the medicament is saved, and the water treatment effect is good.
