The liquid outlet pipe 5 is connected to the hollow shaft 7 through the rotating member 6, and the delivery pump 3 is started, so that the delivery pump 3 draws the neutralizing liquid in the liquid storage box 2 into the liquid outlet pipe 5 through the liquid inlet pipe 4, and enters the hollow shaft 7 through the rotating member 6, so that the neutralizing liquid enters the liquid separation box 9 through the liquid outlet 8, and enters the high-pressure nozzle 11 through the liquid outlet hole 10 to be sprayed into the sewage. An automatic liquid adding component is provided on the liquid storage box 2.A support frame 24 is fixedly provided on the left side of the neutralization box 1, a filter box 25 is fixedly provided on the top of the support frame 24, a partition plate 36 is fixedly provided inside the filter box 25, a conveying pipe 35 is fixedly provided at the bottom of the filter box 25, a filter assembly is provided inside the filter box 25, and a sewage conveying pipe is provided on the top of the filter box 25.

[0031] Specifically, the automatic liquid adding component includes a fixed bottom plate 17, a liquid level sensor 18 and an audible and visual alarm 19. The fixed bottom plate 17 is fixedly installed on the rear side of the liquid storage box 2. The liquid level sensor 18 and the audible and visual alarm 19 are both fixedly installed on the top of the liquid storage box 2. The detection end of the liquid level sensor 18 passes through the liquid storage box 2 and extends to the inside of the liquid storage box 2. A delivery pump 20 is fixedly arranged on the top of the fixed bottom plate 17. A liquid adding pipe 21 is fixedly arranged on the liquid outlet end of the delivery pump 20. The liquid outlet end of the liquid adding pipe 21 passes through the liquid storage box 2 and extends to the inside of the liquid storage box 2. A connecting pipe 22 is fixedly arranged on the surface of the connecting pipe 22. Flange 23 monitors the liquid level of the neutralizing liquid in the liquid storage tank 2 through the liquid level sensor 18. When the neutralizing liquid is too little, the neutralizing liquid can be added to the liquid storage tank 2 through the delivery pump 20, the connecting pipe 22 and the liquid adding pipe 21. During the adding process, the liquid level sensor 18 detects whether the liquid level of the neutralizing liquid increases, and determines whether the delivery pump 20, the connecting pipe 22 and the liquid adding pipe 21 are blocked or faulty. When the liquid level increases, the sound and light alarm 19 can emit sound and light to remind the staff to check the delivery pump 20, the connecting pipe 22 and the liquid adding pipe 21, so as to deal with the fault or blockage, thereby ensuring that there is enough neutralizing liquid in the liquid storage tank 2.

[0032] Specifically, the filter assembly includes a movable plate 26, an electromagnet 27 is adsorbed inside the movable plate 26, and the electromagnet 27 is fixedly installed inside the filter box 25. A mounting groove 28 is provided on the side of the movable plate 26 close to the partition plate 36, and a filter screen 29 is overlapped inside the mounting groove 28. A pulling groove 30 is provided on the side of the filter screen 29 close to the partition plate 36. The sewage conveying pipeline includes a conveying pipe 1 31 and a conveying pipe 2 32. The conveying pipe 1 31 and the conveying pipe 2 32 are both fixedly installed on the top of the filter box 25, and the conveying pipe 1 31 and the conveying pipe 2 32 are symmetrically arranged. Solenoid valves are fixedly installed on the conveying pipe 1 31 and the conveying pipe 2 32. A three-way pipe 33 is fixedly arranged on the surface of the conveying pipe 1 31. The three-way pipe 33 is fixedly connected to the conveying pipe 2 32. A sewage inlet pipe 34 is fixedly arranged inside the three-way pipe 33. By opening the conveying pipe By opening the solenoid valve on the delivery pipe 31 and closing the solenoid valve on the delivery pipe 32, the sewage enters the filter box 25 through the delivery pipe 31 and enters the neutralization box 1 through the delivery pipe 35 on the rear side. At this time, the movable plate 26 on the rear side can be removed to replace the filter screen 29 on the rear side. By opening the solenoid valve on the delivery pipe 32 and closing the solenoid valve on the delivery pipe 31, the sewage enters the filter box 25 through the delivery pipe 32 and is filtered through the filter screen 29 on the front side, and then enters the neutralization box 1 through the delivery pipe 35 on the front side. At this time, the movable plate 26 on the front side can be removed to replace the filter screen 29 on the front side, so that the sewage can still be filtered during the replacement of the filter screen 29, thereby avoiding the failure to filter the sewage due to the replacement of the filter screen 29, resulting in a reduction in the sewage treatment volume.

[0033] When in use: the sewage in the clean laboratory is transported to the inside of the three-way pipe 33 through the delivery pipe 2 32, so that the sewage enters the inside of the filter box 25 through the delivery pipe 1 31 or the delivery pipe 2 32, and is filtered through the filter screen 29 at the rear side. The filtered sewage enters the inside of the neutralization box 1 through the delivery pipe 35 at the rear side, and the delivery pump 1 3 is started. The delivery pump 1 3 draws the neutralization liquid in the liquid storage box 2 into the inside of the liquid outlet pipe 5 through the liquid inlet pipe 4, and enters the inside of the rotating part 6 through the liquid outlet pipe 5, enters the inside of the hollow shaft 7 through the rotating part 6, and enters the inside of the hollow shaft 7 through the surface of the hollow shaft 7. The liquid outlet 8 is arranged to enter the interior of the liquid separation box 9, and then enters the interior of the high-pressure nozzle 11 through the liquid outlet hole 10 arranged on the liquid separation box 9 to be sprayed. Since the neutralizing liquid sprayed by the high-pressure nozzle 11 has a certain pressure, the liquid separation box 9 is pushed to drive the hollow shaft 7 to rotate, so that the lower mounting tube 65 drives the mounting shell 63 to rotate through the connecting bearing 62, so that the hollow shaft 7 drives the stirring plate 13 to rotate through the fixing sleeve 12, and the neutralizing liquid is directly sprayed into the sewage, and the neutralizing liquid is sprayed on different positions of the sewage through the high-pressure nozzles 11 at different positions, so that The neutralizing liquid can be located at different positions inside the sewage at the same time, and the sprayed neutralizing liquid can drive the sewage to rotate, so that the sewage is quickly mixed with the neutralizing liquid under the action of its own rotation and the stirring action of the stirring plate 13. During the consumption of the neutralizing liquid in the liquid storage tank 2, the liquid level of the neutralizing liquid in the liquid storage tank 2 is detected by the liquid level sensor 18. When the liquid level sensor 18 detects that the liquid level of the neutralizing liquid in the liquid storage tank 2 is too low, the delivery pump 20 is started, so that the delivery pump 20 collects the neutralizing liquid in the external storage device or pipeline into the connecting pipe 22. And enter the inside of the liquid adding pipe 21 through the delivery pump 20, and then enter the inside of the liquid storage tank 2 through the liquid adding pipe 21. When the liquid level sensor 18 detects that the liquid level of the neutralizing liquid in the liquid storage tank 2 reaches the preset value, the delivery pump 20 stops running. If the liquid level of the neutralizing liquid in the liquid storage tank 2 does not increase for a long time after the delivery pump 20 is started, it means that the connecting pipe 22 and the liquid adding pipe 21 are blocked, or the delivery pump 20 fails, then the sound and light alarm 19 sends out a sound and light alarm to notify the staff to check the delivery pump 20, the liquid adding pipe 21 and the connecting pipe 22.

[0034] In summary, the neutralizing liquid in the liquid storage box 2 is transported to the inside of the hollow shaft 7 through the delivery pump 3, the liquid inlet pipe 4, the liquid outlet pipe 5 and the rotating member 6, and then enters the inside of the liquid separation box 9 through the liquid outlet 8, and enters the high-pressure nozzle 11 through the liquid outlet hole 10, and then is sprayed into the sewage in the neutralization box 1 through the high-pressure nozzle 11, wherein the neutralizing liquid can be sprayed to different positions inside the sewage through the high-pressure nozzles 11 at different positions, and since the flow rate of the sprayed neutralizing liquid is relatively high, the neutralizing liquid can move in the sewage, then due to the reverse thrust of the neutralizing liquid spraying, the liquid separation box 9 pushes the hollow shaft 7 to rotate through the rotating member 6, so that the hollow shaft 7 drives the stirring plate 13 to stir the sewage through the fixed sleeve 12, and the force of the neutralizing liquid spraying can push the sewage itself to move, thereby increasing the mixing speed of the sewage and the neutralizing liquid, and reducing the mixing time of the sewage and the neutralizing liquid, which is used to solve the problems raised in the above-mentioned background technology.
