Device for adopting atom absorption spectrophotometry for monitoring water quality

Abstract

The invention relates to a device for adopting the atom absorption spectrophotometry for monitoring water quality, and belongs to the technical field of water quality detection equipment. According tothe technical scheme, the device is characterized by comprising a detection table and an isolation cover, a detection sink, a hydride generation atomizer, a water pumping assembly and a cleaning device are arranged inside the isolation cover; the cleaning device comprises a closed cover, a vertical drive piece and a cleaning brush; the cleaning brush comprises a vertically-arranged brush shaft and bristles fixedly connected with the brush shaft, and the brush shaft is rotationally connected with the closed cover around the axis; the bottom of the detection sink is communicated with a drainagepipe, and a switching valve for controlling outflow water is arranged on the drainage pipe; the cleaning device further comprises a rotating piece for driving the brush shaft to rotate; the problem that due to the fact that the number of ions remaining in the detection sink is excessively large, the next water quality detection result is affected is solved; water sample ions remaining in the detection sink can be conveniently and rapidly cleaned, and the water quality sample ion concentration detection result is more accurate.

Description

technical field [0001] The invention relates to the technical field of water quality testing equipment, in particular to a water quality monitoring equipment using atomic absorption spectrophotometry. Background technique [0002] Water is a necessity for people's production and life, and whether drinking water is clean directly affects people's life and health. With the development of society, people's pursuit of health is increasing day by day, and people have higher requirements for the water quality of application water. Water contains many ions, some of which are harmful to the human body. When the harmful ions in the water exceed the standard, people drink it, which will cause great damage to people's health. [0003] The Chinese invention patent application document with the application publication number CN107300526A discloses a device for monitoring water quality by atomic absorption spectrophotometry, including a box body and a table. A movable door is arranged at...
