Sample waste collecting device for heavy metal detection

Abstract

The invention discloses a sample waste collecting device for heavy metal detection. The sample waste collecting device comprises a barrel body and an upper cover, the upper cover is arranged at the upper end of the barrel body; a purification mechanism is arranged between the barrel body and the upper cover; a bearing A is fixedly embedded in the upper end of the upper cover; a rotating rod is fixedly sleeved in the bearing A; the output end of the motor is connected with the upper end of the rotating rod; a through hole is formed in the lower surface in a containing cavity in a penetrating mode. A circular cavity is formed in a rectangular block; a bearing B is fixedly embedded in the surface of the opposite side of the rectangular block, a cylindrical block is movably embedded in the circular cavity, an open groove is formed in the outer surface of the cylindrical block, a shaft rod is connected to the surface of the opposite side of the cylindrical block and fixedly sleeved with thebearing B, and a water outlet is formed in the lower end of the barrel body. The sample waste collecting device is simple in structure and convenient to operate, detected heavy metal sewage can be purified and discharged separately, and pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of sample waste collection for heavy metal detection, in particular to a sample waste collection device for heavy metal detection. Background technique [0002] The heavy metals mentioned in terms of environmental pollution actually mainly refer to metals or metalloids such as mercury, cadmium, lead, chromium, and arsenic, as well as general heavy metals with certain toxicity, such as copper, zinc, nickel, cobalt, and tin. We briefly discuss the hazards of heavy metals from the aspects of naturalness, toxicity, activity and persistence, biodegradability, bioaccumulation, and additive effects on organisms. [0003] Usually, after the heavy metal sewage is detected, there is no special device for collecting the detected heavy metal sewage in the prior art, so it needs to be improved. Contents of the invention [0004] The present invention aims at the problem that there is no special device for collecting t...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at the problem that there is no special device for collecting the detected heavy metal sewage in the above-mentioned prior art. The heavy metal wastewater purification agent is put into the whole body, and then the motor drives the rotating rod to stir. After the completion, the chemical precipitation method is used for precipitation. , and discharged separately, so as to solve the heavy metal sewage after detection
