Mini-type trace water quality online monitoring instrument

Abstract

The invention discloses a mini-type trace water quality online monitoring instrument. A hoisting platform and a main body bracket are coaxially aligned and distributed; each reagent bottle is buckledon the hoisting platform in parallel through an outer ring lug boss; probes correspond to the reagent bottles; a light source, a detection pipe and a temperature sensor are connected with thread holesformed in two sides of a digestion spectrophotometric determination module through threads; a rotary motor shaft is used for controlling the hoisting platform to rotate around the rotary motor shaft;a hoisting motor shaft is connected with a transmission gear; the transmission gear is engaged with a transmission rack; the hoisting movement of the hoisting platform is controlled through the hoisting motor shaft. According to the mini-type trace water quality online monitoring instrument disclosed by the invention, the concentration of trace elements in a test sample is determined by utilizinga probe technology and the space utilization rate is improved by adopting a manner of fixing the probes and rotating the hoisting platform to extracting liquid; cylindrical vertical type installationis adopted and the mini-type trace water quality online monitoring instrument is convenient to mount; a side wall adopts a rotary inner wall door and a rotary outer wall door so that the reagent bottles are convenient to place and the instrument is convenient to maintain; hoisting rotation of reagents is realized through the hoisting platform and the space utilization rate is improved.

Description

technical field [0001] The invention relates to a miniature trace water quality monitoring device, in particular to the qualitative and quantitative analysis of various water quality parameters by ultraviolet spectrophotometry. Background technique [0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in the water body, the concentration and change trend of various pollutants, and evaluating the water quality status. The scope of monitoring is very wide, including unpolluted and polluted natural water (river, river, lake, sea and groundwater) and various industrial drainage. The main monitoring items can be divided into two categories: one is comprehensive indicators reflecting water quality, such as temperature, chromaticity, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand and biochemical oxygen demand etc.; the other category is some toxic substances, such as phenol, cyanide, arse...
