Online water quality analyzer

Abstract

The invention relates to an online water quality analyzer. The online water quality analyzer includes a meter box, a mounting plate, a reagent pump, a sampling pump, a mixing pump and a colorimetric measurement unit, wherein the colorimetric measurement unit includes a cuvette, a light source and a light receiver, the sampling pump is in communication with the mixing pump through a sampling pipeline, the reagent pump is in communication with the cuvette through a reagent pipeline, the cuvette is in communication with the sampling pipeline through a first mixing pipeline, the mixing pump is incommunication with the cuvette through a second mixing pipeline, through setting the mixing pump, the test reagent extracted from the cuvette by the reagent pump and a to-be-sampled sample extracted by the sampling pump are thoroughly mixed and then recycled to the cuvette for detection, manual mixing is not needed, high degree of automation is achieved, in addition, the sampling pump, the reagentpump and the colorimetric measuring unit are integrated into the mounting plate in the meter box, sampling, mixing and detection are integrated into one, high integration and small size are achieved,and the online water quality analyzer is easy for operators to install and use.

Description

technical field [0001] The invention relates to the field of water quality monitoring instruments, in particular to an online water quality analyzer. Background technique [0002] Water quality analyzer is a kind of water quality monitoring tool, which can achieve automatic real-time monitoring of various parameters of water quality, and can be provided to such as tap water supply, medicine, pharmaceuticals, sewage treatment, municipal, power and energy, food processing, plastics, automobiles, semiconductors , tires, metallurgy, material handling, mining, printing and oil and gas industries. The existing water quality analyzer has a complex connection structure of internal parts, a large instrument volume, and requires an external sample delivery pipeline, which has a high space occupancy rate. In addition, the staff needs to manually mix the detection reagent with the sample to be tested before injecting the colorimetric The detection is carried out in a dish, and the oper...
