Embodiment 1
[0045] Embodiment 1. When the membrane treatment equipment is working, there is a pressure difference in the three chambers, and the sewage is filtered through the permeable membrane 15 by using the pressure difference. If the second chamber 12 and the third chamber 13 leak water during the filtration process It will cause the internal pressure to become smaller. At this time, the pressure on the movable rod 24 in the chamber becomes smaller. Under the elastic force of the spring 254, the slider 252 moves along the slider 253 to the second annular pressure sensor 263. At this time, the second annular pressure When the pressure on the sensor 263 exceeds the preset value, an alarm will be sent to the upper computer to remind the staff to check whether the corresponding chamber is leaking.
Embodiment 2
[0046] Embodiment 2, when the permeable membrane 15 is damaged or blocked, the permeable membrane 15 loses its filtering function, which will cause the pressure in the chamber to increase. At this time, the pressure on the movable rod 24 in the chamber becomes larger, and the movable rod 24 is pushed to move outward, driving The slide block 252 moves toward the first annular pressure sensor 262. At this time, the pressure on the first annular pressure sensor 262 becomes larger than the preset value, and an alarm is sent to the upper computer, and the upper computer starts the water pump 32 of the water quality detection mechanism 3. Water is pumped into the transparent water pipe 33, and the spectral transmitter 34 and the spectral receiver 35 are started to detect the water quality. If the water quality deteriorates, it shows that the permeable membrane 15 is damaged and the water pressure in the chamber is increased. If the water quality changes significantly, it indicates th...
Embodiment 3
[0047] Embodiment 3, when the pressure change in the chamber causes the movable rod 24 to move, the waterproof cleaning ring 242 will also move at this time, and the inner wall of the monitoring box 21 can be cleaned to prevent the impurities of the sewage from sticking to the inner wall and destroy the sealing of the sealing ring 241. At the same time The designed micro-air pump 2411 and one-way valve 2412 can ensure a certain air pressure between the sealing ring 241, and prevent the sewage in the chamber from leaking under the pressure difference after a long time of work, and seep into the sealing ring 241 and the monitoring box twenty one.
[0048] Beneficial effects are as follows:
[0049] The waterproof cleaning ring 242 designed inside the monitoring box 21 designed by the present invention can move with the movable rod 24 to clean the remaining impurities on the inner wall of the monitoring chamber 21 to prevent damage to the sealing ring 241, and the designed micro ...
