Lifting type automatic reagent feeding and cleaning system for online immersive type detection electrode probe

Abstract

The invention discloses a lifting type automatic dosing and cleaning system for an online immersive detecting electrode probe. The system comprises an air inlet shut-off valve and a flushing water shut-off valve; the outlet of the air inlet shut-off valve is connected with a first air filtering pressure reducing valve and a second air filtering pressure reducing valve; the outlet of the first airfiltering pressure reducing valve is connected with the first solenoid valve inlet of an explosion-proof two-position five-way solenoid valve; the outlet of the flushing water shut-off valve is connected with a filter, a second explosion-proof two-way solenoid valve, a second flow meter and a second one-way valve sequentially; an air cylinder is disposed on a supporting frame; the supporting frameis provided with a flushing ring; and an end portion of the piston rod of the air cylinder is provided with an electrode bracket and an electrode. With the lifting type automatic dosing and cleaningsystem for the online immersive detecting electrode probe of the invention, the automatic irregular cleaning function of electrodes can be realized; and the lifting and lowering action of electrode probes is realized by the air cylinder. The system has the advantages of simple structure, and reliable operation.

Description

technical field [0001] The invention relates to an on-line detection tool, more precisely, an up-and-down automatic dosing and cleaning system for an on-line submerged detection electrode probe. Background technique [0002] PH electrode, conductivity electrode and dissolved oxygen electrode, as an electrochemical analysis instrument, have a wide range of applications from routine to professional measurement, involving petroleum, chemical, chemical, pharmaceutical, food and various other laboratories or production, etc. . The installation methods of electrodes include process pipeline in-line type, flow cell installation type and immersion type, etc. For the first two, the process medium is relatively clean, and the pollution to the electrode surface is relatively light. For the immersion installation method, the electrode is generally immersed in the on-site process pool directly, and the on-site process pool contains grease, organic matter, metal particles and There are ...

AI Technical Summary

Problems solved by technology

For the first two, the process medium is relatively clean, and the pollution to the electrode surface is relatively light. For the immersion installation method, the electrode is generally immersed in the on-site process pool directly, and the on-site process pool contains grease, organic matter, metal particles and There are many impurities, etc., the surface of the electrode may soon be adhered by grease and impurities, which greatly affects the measurement results, and even leads to failure to measure
