Description
Technical field
The utility model relates to a kind of heavy metal analyser device, especially is suitable for the heavy metal check and analysis instrument of water body.
Background technology
Some heavy metal analysers in the market, according to detecting the principle difference, can be divided into several, a kind of is to adopt the ultraviolet-visible light spectrophotometric method, this kind detector advantage is that cost is low, but it is single to survey parameter, and monitoring periods is long, influenced greatly by tested water quality colourity, monitoring accuracy can not get reliable assurance; Need to use poisonous reagent in the analytic process simultaneously, its waste liquid can produce serious secondary pollution to environment, even causes the situation of surveying and more polluting; Another kind is the analyser that adopts anodic stripping voltammetry, and its core component electrode all depends on import, the replacement cost height.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, but provides a plurality of heavy metal parameters of a kind of fast detecting also can be widely used in the analyser in many water quality field.
The purpose of this utility model is finished by following technical solution, and heavy metal check and analysis instrument is made of sample feeding module, sensing measurement module, central control module; The sample feeding module connects the hyperchannel selector valve by syringe pump, each port of hyperchannel selector valve connects reagent bottle respectively, reagent bottle is divided into mercury, chromium, cadmium, lead, arsenic five kinds of marks liquid bottle and sampling jar, and sampling pump connects sampling jar, and sampling pump is pumped into sampling jar with tested water sample; The sensing measurement module comprises ultrasonic bathing pool, and this ultrasonic bathing pool top is provided with the electrolytic cell body, and this Chi Tishang is provided with electrode, and ultrasonic bathing pool bottom is provided with detects electrolysis detection cup; Syringe pump connects ultrasonic bathing pool, connects the valve injection pump by hyperchannel quantitative water sample is pumped into ultrasonic bathing pool from reagent bottle; Central control module connects embedded controller by PC, and this controller connects pump valve controller and data processing module respectively, and the pump valve controller connects syringe pump, and data processing module connects electrolysis and detects cup.
This project of the utility model product can be widely used in water quality emergency monitoring, the comparison monitoring of water and waste water, at its measurement advantage and function thereof, can be mainly used in the water quality emergency monitoring and the comparison monitoring of industrial pollution source, potable water, cross section of river surface water.Because the existence form of heavy metal element is various in the water, the ionic species that has exists; What have exists with aerosol form; What have then exists with precipitated form.The routine measurement method generally can only be measured the heavy metal element that ionic species exists, and can not embody the total concentration of certain heavy metal element in the water.The utility model is not subjected to the solid-state and influence ionic state existence form, the total concentration of the heavy metal element in can complete detection water sample.
Description of drawings
Fig. 1 is the structural representation of each module of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done detailed introduction:
As shown in Figure 1: heavy metal check and analysis instrument is made of sample feeding module, sensing measurement module, central control module; The sample feeding module connects hyperchannel selector valve 5 by syringe pump 4, hyperchannel selector valve 5 each port connect reagent bottle 6 respectively, reagent bottle is divided into mercury, chromium, cadmium, lead, arsenic five kinds of marks liquid bottle and sampling jar, and sampling pump connects sampling jar, and sampling pump is pumped into sampling jar with tested water sample; The sensing measurement module comprises ultrasonic bathing pool 9, and this ultrasonic bathing pool top is provided with electrolytic cell body 8, and this Chi Tishang is provided with electrode, and ultrasonic bathing pool 9 bottoms are provided with detects electrolysis detection cup 10; Syringe pump 4 connects ultrasonic bathing pool 9, connects the valve injection pump by hyperchannel quantitative water sample is pumped into ultrasonic bathing pool from reagent bottle; Central control module connects embedded controller 2 by PC 1, and this controller 2 connects pump valve controller 3 and data processing module 7 respectively, and pump valve controller 3 connects syringe pump 4, and data processing module 7 connects electrolysis and detects cup 10.
The routine measurement method generally can only be measured the heavy metal element that ionic species exists, and can not embody the total concentration of certain heavy metal element in the water.The utility model sensing measurement module comprises ultrasonic bathing pool, has introduced ultrasound wave, has reduced the influence of heavy metal solid-state form, the total concentration of the heavy metal element in can complete detection water sample.
