AI Technical Summary

Technical Problem

In existing wastewater heavy metal chelating agent release and monitoring devices, the chelate precipitates tend to float and move, affecting the accuracy of heavy metal ion content detection and reducing treatment efficiency.

Method used

A device comprising a tank, a stirring mechanism, and a collection mechanism was designed. The stirring mechanism, driven by a motor, causes the chelates deposited above the filter screen to pass through a channel into the area below the filter screen. Combined with the vortex effect, the chelates are prevented from floating back to the surface. The support made of elastic material facilitates the disassembly and cleaning of the filter screen.

Benefits of technology

It improves the accuracy of heavy metal ion content detection, ensures precise control of chelating agent release, avoids waste of chelating agent, and enhances wastewater treatment efficiency.

Abstract

The utility model discloses a sewage heavy metal chelating agent releasing and monitoring device which comprises a tank body, a water outlet pipe is arranged on the side wall of the tank body, a blow-off pipe is arranged in the middle of the bottom end of the tank body, a detection device used for detecting the content of heavy metal is arranged on the side wall of the tank body in a penetrating mode, and a top cover is installed on the top of the tank body through a hinge. A conveying pipe and a liquid preparation pipe are arranged at the upper end of the top cover in a penetrating manner; a motor is mounted at the top of the top cover, and an output shaft of the motor is hermetically connected with the top cover in a penetrating manner and connected with a stirring mechanism; a collecting mechanism is arranged in the tank body and comprises a support, a filter screen is installed on the support, an extending part is arranged in the center of the filter screen, a vertical through groove is formed in the extending part, and the diameter of the middle of the through groove is smaller than that of the upper end and the lower end of the through groove. According to the utility model, the chelate deposited on the filter screen enters the lower part of the filter screen through the through groove by virtue of the collecting mechanism, so that the problem that the chelate floats upwards again after being deposited is relieved, and the treatment effect is improved.
