[0023] Among them, the sealing assembly is composed of a sealing inner plate 10, a slider 11 and a sealing outer plate 12. The sealing inner plate 10 is fixedly connected to the bottom of the movable plate 8. The sealing inner plate 10 is an arc-shaped plate and slides in contact with the inner wall of the processing tube 1. The slider 11 is fixedly connected to the outer arc surface of the sealing inner plate 10. The slider 11 is slidingly connected to the slide groove 20. The other end of the slider 11 is fixedly connected to the sealing outer plate 12.

[0030] The utility model provides a pretreatment mechanism for water quality detection, and the specific working principle is as follows:

[0031] When in use, water will enter the treatment cylinder 1 through the water inlet 3 and pass through the filter plate 21 for pretreatment. When the filter plate 21 is not blocked, the drainage speed of the filter plate 21 is greater than the water inlet speed of the water inlet 3, and no water will accumulate on the filter plate 21. At this time, the conductive block 13 will not contact the electrode sheet 19. Figure 6As shown in Figure 1, with the long-term use of the pretreatment equipment, impurities will gradually accumulate on the filter plate 21, and the drainage speed of the filter plate 21 will gradually decrease. When the drainage speed of the filter plate 21 is less than the water inlet speed of the water inlet 3, water will accumulate on the filter plate 21. The increase in weight will cause the filter plate 21 to move downward continuously and drive the conductive block 13 to move downward. When the conductive block 13 moves downward and contacts the two conductive electrode sheets 19, the connecting circuit between the display light 17 and the built-in power supply 18 will be connected, so that the display light 17 lights up, thereby reminding the staff to replace the filter plate 21. The equipment can promptly remind the staff to replace the filter plate 21 when it is blocked, so as to avoid the continuous entry of water into the treatment tube 1 after the blockage, causing the internal parts of the treatment tube 1 to be damaged by water.
