[0032] When the baffle 27 moves, the insertion ring 39 enters the sealing groove 37, the inclined surface of the insertion ring 39 contacts the sealing ring 38, the pressure of the insertion ring 39 on the sealing ring 38 makes the sealing ring 38 compressed, when the insertion ring 39 completely enters the sealing groove 37, the elasticity of the sealing ring 38 reduces the gap between them, so as to reduce the probability of moisture entering the limiting groove 23.

[0033] Working principle: when in use, the staff puts the water sample and a proper amount of coagulant into the filter box 4 from the water inlet pipe 9. At this time, the water sample will accumulate on the top of the partition plate 18 because the movable bar 28 is at the bottom of the through hole 19. At this time, the staff starts the motor 14, the rotating shaft 15 rotates, drives the stirring rod 16 to rotate, and accelerates the mixing efficiency of the coagulant and the water sample. When the colloidal particles have coagulation effect and form larger flocculation particles, the staff starts the electromagnet 24, the iron movable plate 26 is attracted into the limiting groove 23, the spring 25 is compressed, the movable plate 26 drives the movable bar 28 to move through the baffle 27, the movable bar 28 no longer blocks the through hole 19, at this time, the water sample can leave from the through hole 19, at this time, the scraper 17 pushes away the precipitate accumulated on the top of the partition plate 18, improves the filtering efficiency, so as to complete the cleaning of the colloidal substance and improve the monitoring accuracy. When the baffle 27 moves, the insertion ring 39 enters the sealing groove 37, the inclined surface of the insertion ring 39 contacts the sealing ring 38, the pressure of the insertion ring 39 on the sealing ring 38 makes the sealing ring 38 compressed, when the insertion ring 39 completely enters the sealing groove 37, the elasticity of the sealing ring 38 reduces the gap between them, so as to reduce the probability of moisture entering the limiting groove 23. When monitoring, the staff opens the second electromagnetic valve 13, the water sample enters the monitor 3 from the measuring pipe 12, and the monitoring is carried out. When the monitoring is completed, the staff opens the first electromagnetic valve 11, and the residual water sample can leave the filter box 4. When cleaning the partition plate 18, the staff rotates the handle 35, the threaded rod 34 rotates, and then drives the clamping block 36 to leave the clamping groove 31, at this time, the staff can pull out the insertion plate 30, remove the box cover 5, and finally pull the pull plate 21, so as to take out the partition plate 18, which is convenient for cleaning.
