The sewage is introduced into the sorting component at the top for diversion, so as to remove the first harmful substance in the filter cylinder. Then, the sewage is introduced into the sorting component at the bottom for diversion, so as to remove the second harmful substance in another group of filter cylinders. By repeating this cycle, various chemical pollutants in the sewage are removed step by step to solve the problem of waste of chemical agents in the existing automatic filtering device for water treatment.

[0020] 1. In the present invention, the height of the oil screening ring plate is adjusted by the telescopic cylinder, so that the screen opening gradually moves down along the top surface of the oil and grease pollutant layer. The oil and grease pollutant layer automatically slides into the reaction kettle through the screen opening and the oil outlet pipe and gradually becomes thinner.

[0021] 2. During the oil screening process of the present invention, there may still be some sewage splashing into the reaction kettle. By driving the stirring frame to rotate through the first driving motor, the oil pollutant and the oil removal regulator can be quickly mixed. Then, the second solenoid valve is opened, and the mixed sewage is screened through the screen to screen out the precipitates, polymers, etc. generated by the reaction. Then, the circulation pump is started, and the sewage is pumped back into the lower kettle body through the circulation pipe, accelerating the oil removal reaction rate.

With the above structure, the remaining oil pollutants can be fully screened out, further improving the elimination effect of the oil pollutants.

[0023] 4. The present invention stably generates tiny bubbles through the bubble generator, and uses the bubbles to bring the solid particles or suspended substances in the sewage to the water surface, and pumps them into the reaction kettle together with the oil, for filtration treatment. The two sewage treatment steps of particle screening and oil pollutant elimination can be carried out simultaneously, thereby improving the sewage treatment efficiency.

[0047] For a further second embodiment, please refer to Figure 2 、 Figure 5 and Figure 6 as shown:

[0048] It further includes a reaction circulation assembly 3 for accelerating the action rate of the medicament and circulating the excess sewage back into the lower kettle body 102.

[0049] Among them, a solenoid valve 2 is installed at the input end of the sieve mesh 303.

[0050] Specifically, during the oil screening process, some sewage may still splash into the reaction kettle 106. By driving the stirring frame 302 to rotate through the driving motor 301, the grease pollutants and the oil removal regulator can be quickly mixed. Then, the solenoid valve 2 is opened, and the mixed sewage is screened through the sieve mesh 303 to screen out the precipitates, polymers, etc. generated by the reaction.

[0053] For a further Embodiment 3, please refer to Figure 2 、 Figure 7 and Figure 8 as shown in:

[0054] A second oil screening assembly 4 is provided on the water inlet pipe 110, and a plurality of bubble generators 5 are evenly distributed at the bottom of the inner cavity of the lower kettle body 102. The second oil screening assembly 4 includes a floating ring airbag 401 slidably sleeved on the water inlet pipe 110 vertically. A lower ring body 402 is rotatably sleeved on the outer side of the floating ring airbag 401. A waterproof ring sleeve 403 is fixedly connected to the bottom surface of the floating ring airbag 401. A toothed ring 404 is fixedly installed inside the waterproof ring sleeve 403. A driving motor two 405 is fixedly installed on the bottom surface of the lower ring body 402. The output end of the driving motor two 405 is fixedly connected to a spur gear 406. The toothed ring 404 meshes with the spur gear 406. A second sealing ring 407 is provided between the outer ring of the waterproof ring sleeve 403 and the lower ring body 402. An upper ring body 408 is fixedly sleeved on the outer side of the floating ring airbag 401. The upper ring body 408 fits on the top surface of the lower ring body 402. A plurality of hanging pipes 409 are fixedly communicated with the outer side of the lower ring body 402. A plurality of oil inlet holes 410 are evenly formed in the hanging pipes 409. An oil suction nozzle 411 is installed through the upper ring body 408. The top of the oil suction nozzle 411 is communicated with an oil suction pipe 412. A mounting plate 413 is fixedly installed on the sieve opening 204. An oil suction pump 414 is fixedly installed on the mounting plate 413. The input end of the oil suction pump 414 is communicated with one end of the oil suction pipe 412 away from the oil suction nozzle 411. The output end of the oil suction pump 414 is fixedly communicated with a spray oil pipe 415.

[0055] Specifically, the driving motor two 405 drives the spur gear 406 to roll meshingly along the outer edge of the toothed ring 404, and then drives the lower ring body 402 to rotate along the surface of the floating ring airbag 401, so that the hanging pipes 409 scrape and gather the oil pollutant layer together, facilitating the centralized treatment of the oil pollutants. Then, the oil suction pump 414 is started to pump the oil pollutant layer into the reaction kettle 106 through the oil suction pipe 412 and the oil suction nozzle 411, and it is sprayed into the reaction kettle 106 through the spray oil pipe 415.

[0056] Among them, the bubble generator 5 is a prior art, which is used to stably generate minute bubbles, and use the bubbles to bring the solid particles or suspended matters in the sewage to the water surface, and pump them into the reaction kettle 106 together with the oil for filtration treatment.

[0057] Preferably, an air nozzle for deflating and refilling air is provided on the floating ring airbag 401. When the sewage floats the floating ring airbag 401, the oil suction end of the oil suction nozzle 411 is exactly located at the oil-water stratification position, and the hanging pipe 409 is of an arc structure.

[0058] Among them, the buoyancy of the floating ring airbag 401 can be adjusted through the air nozzle, so that both the oil inlet hole 410 and the oil suction end of the oil suction nozzle 411 are located at the oil-water stratification position. At the same time, the suction force generated by the oil suction pump 414 can drive the sewage and the grease pollutant layer to pass through the oil inlet hole 410 and the lower ring body 402 in sequence and be sucked by the oil suction nozzle 411. Moreover, the upper ring body 408 and the lower ring body 402 are sealed to ensure the suction force at the oil inlet hole 410.

[0059] The working principle of all the contents in the above embodiments is as follows:

[0060] During use, the sewage enters the lower kettle body 102 through the water inlet pipe 110. After the sewage and the grease pollutants are statically stratified, the height of the oil screening ring plate 203 is adjusted by the telescopic cylinder 202, so that the screening port 204 gradually moves down along the top surface of the grease pollutant layer. The grease pollutant layer automatically slides into the reaction kettle 106 through the screening port 204 and the oil outlet pipe 105 and gradually becomes thinner. Then, the solenoid valve 1 is opened, so that the oil removal regulator is injected into the reaction kettle 106 through the medicine delivery pipe 109. The grease pollutant and the oil removal regulator are mixed for oil removal. Then, the stirring frame 302 is driven to rotate by the driving motor 1 301, and the grease pollutant and the oil removal regulator can be quickly mixed and reacted. Then, the solenoid valve 2 is opened, and the mixed sewage is screened through the screen 303 to screen out the precipitates, polymers, etc. generated by the reaction. Then, the circulation pump 304 is started, and the sewage is pumped back into the lower kettle body 102 through the circulation pipe 305.

[0061] During the process of screening oil through the first oil screening assembly 2 to the reaction circulation assembly 3 for stirring and mixing the grease pollutant and the oil removal regulator, there will still be some residual grease pollutants. At this time, the driving motor 2 405 drives the spur gear 406 to roll meshingly along the outer edge of the toothed ring 404, and then drives the lower ring body 402 to rotate along the surface of the floating ring airbag 401, so that the hanging pipe 409 scrapes and gathers the grease pollutant layer together. Then, the oil suction pump 414 is started, and the grease pollutant layer is pumped in through the oil suction pipe 412 and the oil suction nozzle 411, and is sprayed into the reaction kettle 106 through the spray oil pipe 415, and then the grease pollutant is fully mixed and reacted through the reaction circulation assembly 3.

[0062] After the grease pollutants are fully reacted and eliminated, the switch valve 112 is opened, and the sewage is discharged through the water outlet pipe 111 to perform subsequent sewage treatment steps.
