Environment-friendly utilization device for recycling zinc sulfate production waste residues

Abstract

The invention discloses an environment-friendly utilization device for recycling zinc sulfate production waste residues. The environment-friendly utilization device comprises a tank body, wherein a feeding tube and a supply tube are arranged on the left side of the top of the tank body; a cap is connected with the top of the side surface of the supply tube in a threaded sleeving manner; a drivingmotor is fixedly mounted at the top of the tank body; the output end of the driving motor is fixedly connected with a speed reducer; a shaft rod is fixedly connected with the bottom end of the speed reducer. Zinc powder in precipitate collected from a filtering cylinder can be effectively utilized, so that the utilization rate of the zinc powder is increased, waste of a zinc powder material is avoided, and the cost of materials is lowered; in addition, a threaded rod fixed with a first bevel gear is driven to rotate by a second bevel gear by rotating a rotating handle, and a threaded sleeve and a filtering cylinder are moved upwards, so that the precipitate is conveniently taken out from an overhaul hole and is collected and recycled, the consequence that production is affected as the precipitate is accumulated in a tank is avoided, manual cleaning in the tank is avoided, and consumption of labor can be reduced.

Description

technical field [0001] The invention relates to the technical field of waste slag recovery and utilization devices, in particular to a waste slag recovery and environmental protection utilization device for zinc sulfate production. Background technique [0002] In the production of zinc sulfate, impurities need to be removed from the filtrate. The filtrate needs to be sent to the replacement reactor and heated to 80°C. Add zinc powder to replace heavy metal impurities such as copper and lead, and then filter out the replacement hydraulic pressure to replace copper and lead. Heavy metals, in order to improve the purity of zinc sulfate in the replacement solution, it is necessary to add too much zinc powder to carry out a chemical reaction to replace all the heavy metals such as copper and lead in the filtrate, but too much zinc powder cannot be completely reacted and used up. It will be filtered out and discarded along with metals such as copper and lead, resulting in the was...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an environmental protection utilization device for recycling the waste slag used in zinc sulfate production, which solves the problem that too much zinc powder cannot be completely reacted and used up, and it will be filtered out along with metals such as copper and lead and discarded. , resulting in the waste of heavy metal materials such as zinc, copper and lead, and at the same time increasing the cost of material loss, and the accumulation of long-term non-discharge, which makes the sediment affect the entire production process, requires manual cleaning in the tank, labor intense problem
