Description

A kind of electrochemical cell

Technical field

The utility model relates to online environment monitoring and analytical chemistry field, in particular a kind of electrochemical cell.

Background technology

Electrochemical detection method is widely used in the context of detection of heavy metal monitoring and poisonous element.Adopt leaching can detect heavy metal elements such as copper, lead, cadmium, zinc, thallium, mercury, arsenic, chromium, manganese, iron, antimony, easier and highly sensitive than classic method.This method on-line monitoring appearance has been applied to monitorings such as drinking water source ground, surface water, tap water, river, lake water, seawater, pollution source.Because galvanochemistry itself is highly sensitive, so reappearance and accuracy depend on the degree of cleaning of electrolytic cell, so in the industry the cleaning performance of electrolytic cell is had higher requirement.

Summary of the invention

The utility model problem to be solved provides a kind of electrochemical cell of easy cleaning.

The technical scheme that the utility model adopted is: electrochemical cell comprises the electrolytic cell body; Said electrolytic cell body is provided with working electrode, contrast electrode, auxiliary electrode; One end of said working electrode, contrast electrode, auxiliary electrode places in the electrolytic cell body; Said working electrode and auxiliary electrode form current return; Working electrode and contrast electrode form the no current path, and said electrolytic cell body is provided with liquid outlet and an above inlet, and said electrolytic cell body bottom is the high end of an end low arc slope or slope shape structure; A said above inlet is located at high-end place, electrolytic cell body bottom, and said liquid outlet is located at electrolytic cell body bottom lower end.

In the such scheme, also be provided with on the preferred said electrochemical cell body and be connected with a motor fixing frame, be fixed with a stirring motor on the said motor fixing frame, said stirring motor drive one is stretched into the intrinsic stirring-head rotation of electrolytic cell and is played beating action.

In the such scheme, in the preferred said electrolytic cell body, be provided with the solution reagent pipe and be fixedly connected on inlet through joint, evacuated tube is fixedly connected on liquid outlet through joint, gets into and outflow electrolytic cell and electrolytic cell body for solution.

In the such scheme, preferred said solution reagent pipe and joint are located in the electrolytic cell body sidewall.

In the such scheme, preferred said contrast electrode oblique cutting is gone in the electrolytic cell body, and said working electrode and auxiliary electrode adopt Matheson and Dresser joint and electrolytic cell body to join respectively.

In the such scheme, the direct subtend electrolytic cell of preferred said inlet body bottom is high-end but depart from working electrode.

The beneficial effect of the utility model is: it is low that the electrolytic cell body bottom in the utility model is the high end of an end; Form the effect of current scour; If further cooperate the stirring of motor; Reach the effect that is prone to cleaning, arc slope or slope shape structure have also reduced the volume of electrolytic cell simultaneously, can effectively reduce the consumption of reagent and the maintenance of on-line monitoring equipment.
