The grease pollutant layer automatically slides into the reactor through the screen mouth and the oil outlet pipe and gradually becomes thinner.

Then, the circulation pump is started to pump the sewage back into the lower reactor through the circulation pipe to accelerate the oil removal reaction rate. At the same time, it is convenient for the sewage to fully circulate into the lower reactor and be discharged for subsequent treatment steps.

[0022] 3.

Then, the oil suction pump is started to pump the grease pollutant layer into the reactor through the oil suction pipe and the oil suction nozzle, and then sprayed into the reactor through the oil injection pipe. Using the above structure, the remaining grease pollutants can be fully screened out, further improving the grease pollutant elimination effect.

[0023] 4. The present invention generates tiny bubbles stably through a bubble generator, and uses the bubbles to bring solid particles or suspended matter in sewage to the water surface, and pumps them into the reactor together with grease for filtration treatment.

[0039] Example 1, please refer to Figures 1 to 5 As shown:

[0040] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides an automatic filtering device for water treatment, including a kettle base 101, a lower kettle body 102 is fixedly installed on the kettle base 101, an upper kettle body 103 is arranged directly above the lower kettle body 102, the upper kettle body 103 is fixedly connected to the lower kettle body 102 through an arc connecting rod 104, a first oil screening component 2 is arranged between the lower kettle body 102 and the upper kettle body 103, an oil outlet pipe 105 is fixedly connected to the first oil screening component 2, and a reactor 106 is fixedly connected to the oil outlet pipe 105 away from the first oil screening component 2. A bracket 107 is fixedly installed on the top of 106, and a drug storage cartridge 108 is fixedly installed on the bracket 107. The bottom of the drug storage cartridge 108 is fixedly connected with a drug delivery pipe 109. The end of the drug delivery pipe 109 away from the drug storage cartridge 108 passes through the oil outlet pipe 105, which is used to inject the medicine into the reaction kettle 106 through the oil outlet pipe 105. A solenoid valve 1 is provided on the drug delivery pipe 109 to control the switch of the drug delivery pipe 109. A water inlet pipe 110 is fixedly connected at the center of the upper kettle body 103, and a water outlet pipe 111 is fixedly connected to the bottom of the lower kettle body 102, and a switch valve 112 is provided on the water outlet pipe 111.

[0041] Preferably, the oil outlet pipe 105 is an inclined structure, and the side of the oil outlet pipe 105 connected to the first oil screening assembly 2 is higher than the side of the oil outlet pipe 105 connected to the reactor 106, so that the oil layer can automatically slide into the reactor 106 along the oil outlet pipe 105 by its own gravity.

[0042] Preferably, the first oil screening assembly 2 includes a telescopic cylinder 202, and a slide groove 201 is provided on the lower kettle body 102 and the upper kettle body 103. The telescopic cylinder 202 is fixedly installed on the top of the upper kettle body 103. The telescopic end of the telescopic cylinder 202 is fixedly connected with an oil screening ring plate 203. The oil screening ring plate 203 can slide up and down in the lower kettle body 102 and the upper kettle body 103 through the slide groove 201. A screen opening 204 is provided on the oil screening ring plate 203. The oil screening ring plate 203 is fixedly connected to the oil outlet pipe 105 through the screen opening 204. A sealing ring 205 is provided between the oil screening ring plate 203 and the lower kettle body 102, and between the oil screening ring plate 203 and the upper kettle body 103.

[0043] Specifically, the height of the oil screen ring plate 203 is adjusted by the telescopic cylinder 202, so that the screen opening 204 gradually moves downward along the top surface of the grease contaminant layer, and the grease contaminant layer automatically slides into the reactor 106 through the screen opening 204 and the oil outlet pipe 105, gradually becoming thinner. Then, the solenoid valve 1 is opened to allow the oil removal regulator to be injected into the reactor 106 through the drug delivery tube 109, and the grease contaminants are mixed with the oil removal regulator for oil removal.

[0044] Furthermore, in the automated filtering device for water treatment of the present invention, by arranging a sensor for detecting oil-water stratification at a suitable position, the telescopic cylinder 202 can be controlled to automatically adjust the height of the sieve opening 204, thereby improving the overall automation of the device.

[0045] Preferably, the height of the bottom port of the water inlet pipe 110 is lower than the lowest height of the sieve mouth 204. When the sewage level is close to the sieve mouth 204, large splashes of water are avoided, which may cause part of the sewage to splash into the reactor 106 through the sieve mouth 204, and the axial lines of the lower reactor body 102, the upper reactor body 103 and the oil screen ring plate 203 to overlap.

[0046] Preferably, the oil screen ring plate 203 is made of a transparent material for observing the boundary between the grease pollutant layer and the sewage layer.

[0047] For further example 2, please refer to Figure 2 , Figure 5 and Figure 6 As shown:

[0048] It also includes a reaction circulation component 3 for accelerating the action rate of the agent and circulating excess sewage to the lower kettle body 102. The reaction circulation component 3 includes a drive motor 301, which is fixedly installed on the oil outlet pipe 105. The output end of the drive motor 301 is fixedly connected to a stirring frame 302. A screen 303 is fixedly installed in the reactor 106. The bottom of the reactor 106 is fixedly connected to the screen 303. The screen 303 is located below the stirring frame 302. The output end of the screen 303 is connected to the upper kettle body 103 through a circulation pipe 305.

[0049] Wherein, a second solenoid valve is installed at the input end of the screen 303 .

[0050] Specifically, some sewage may still splash into the reactor 106 during the oil screening process. By driving the stirring frame 302 to rotate by the driving motor 1 301, 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 screen 303. The precipitate, polymer, etc. produced by the reaction are screened, and then the circulation pump 304 is started to pump the sewage back into the lower kettle body 102 through the circulation pipe 305.

[0051] Furthermore, the reaction circulation component 3 also includes an annular tube 306 and a boost nozzle 307. The annular tube 306 is fixedly installed in the oil outlet pipe 105. The annular tube 306 is connected to the end of the drug delivery tube 109 away from the drug storage cartridge 108, and the axes of the stirring frame 302, the annular tube 306 and the reactor 106 are overlapped. The bottom annular array of the annular tube 306 is connected to multiple boost nozzles 307, and the output end of the boost nozzle 307 sprays obliquely toward the axis of the stirring frame 302.

[0052] Specifically, part of the grease pollutants will slide along the oil outlet pipe 105 onto the stirring frame 302. At this time, the oil removal regulator enters the annular pipe 306 and is sprayed onto the stirring frame 302 through the booster nozzle 307, further flushing the grease pollutants and reacting and mixing.

[0053] For further example 3, please refer to Figure 2 , Figure 7 and Figure 8 As shown:

[0054] The water inlet pipe 110 is provided with a second oil screening assembly 4, 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 which is vertically slidably sleeved on the water inlet pipe 110, and the outer side of the floating ring airbag 401 is rotatably sleeved with a lower ring body 402, and the bottom surface of the floating ring airbag 401 is fixedly connected with a waterproof ring sleeve 403, and the inner side of the waterproof ring sleeve 403 is fixedly installed with a gear ring 404, and the bottom surface of the lower ring body 402 is fixedly installed with a driving motor 2 405, and the output end of the driving motor 2 405 is fixedly connected with a spur gear 406, and the gear ring 404 is meshed with the spur gear 406, and a gear ring 404 is provided between the outer ring of the waterproof ring sleeve 403 and the lower ring body 402. A sealing ring 407 is provided, and an upper ring body 408 is fixedly sleeved on the outer side of the floating ring airbag 401, and the upper ring body 408 is attached to the top surface of the lower ring body 402. A plurality of hanging pipes 409 are fixedly connected to the outer side of the lower ring body 402, and a plurality of oil inlet holes 410 are evenly opened on the hanging pipes 409. An oil suction nozzle 411 is installed through the upper ring body 408, and the top of the oil suction nozzle 411 is connected to an oil suction pipe 412. A mounting plate 413 is fixedly installed on the sieve mouth 204, and an oil suction pump 414 is fixedly installed on the mounting plate 413. The input end of the oil suction pump 414 is connected to the end of the oil suction pipe 412 away from the oil suction nozzle 411, and the output end of the oil suction pump 414 is fixedly connected to an oil injection pipe 415.

[0055] Specifically, the spur gear 406 is driven by the driving motor 405 to mesh and roll along the outer edge of the gear ring 404, and then the lower ring body 402 is driven to rotate along the surface of the floating ring airbag 401, so that the hanging pipe 409 scrapes the grease pollutant layer together to facilitate centralized treatment of the grease pollutants. Then, the oil suction pump 414 is started to pump the grease pollutant layer into the oil suction pipe 412 and the oil suction nozzle 411, and spray it into the reactor 106 through the oil injection pipe 415.

[0056] Among them, the bubble generator 5 is a prior art, which is used to stably generate tiny bubbles, and use the bubbles to bring solid particles or suspended matter in the sewage to the water surface, and pump them into the reactor 106 together with the grease for filtering and treatment.

[0057] Preferably, the floating ring airbag 401 is provided with an air nozzle for deflating and replenishing air. When the floating ring airbag 401 is floated by sewage, the oil suction end of the oil suction nozzle 411 is just located at the oil-water stratification point, and the hanging pipe 409 is an arc-shaped structure.

[0058] Among them, the buoyancy of the floating ring airbag 401 can be adjusted through the air nozzle, so that the oil inlet hole 410 and the oil suction end of the oil suction nozzle 411 are both located at the oil-water stratification. 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 into the oil suction nozzle 411, and 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] Everything in the above example works like this:

[0060] When in use, sewage enters the lower kettle body 102 through the water inlet pipe 110. After the sewage and grease pollutants are allowed to stand and stratify, the height of the oil screen ring plate 203 is adjusted by the telescopic cylinder 202, so that the screen opening 204 gradually moves downward along the top surface of the grease pollutant layer. The grease pollutant layer automatically slides into the reactor 106 through the screen opening 204 and the oil outlet pipe 105 and gradually becomes thinner. Then, the solenoid valve 1 is opened to allow the oil removal regulator to be injected into the reactor 106 through the drug delivery tube 109. The grease pollutants are mixed with the oil removal regulator for oil removal. Then, the stirring frame 302 is driven to rotate by the driving motor 1 301, so that the grease pollutants 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, and the precipitates, polymers, etc. produced by the reaction are screened. Then, the circulation pump 304 is started to pump the sewage back into the lower kettle body 102 through the circulation pipe 305.

[0061] In the process of screening the oil through the first oil screening component 2 and stirring and mixing the grease pollutants and the oil removal regulator in the reaction circulation component 3, some grease pollutants will still remain. At this time, the spur gear 406 is driven by the driving motor 2 405 to mesh and roll along the outer edge of the gear ring 404, and then the lower ring body 402 is driven to rotate along the surface of the floating ring airbag 401, so that the hanging pipe 409 scrapes the grease pollutant layer together, and then the oil suction pump 414 is started to pump the grease pollutant layer into the reaction kettle 106 through the oil injection pipe 415, and then the grease pollutants are fully mixed and reacted through the reaction circulation component 3.

[0062] After the grease pollutants are fully reacted and eliminated, the switch valve 112 is opened to discharge the sewage through the outlet pipe 111, and the subsequent sewage treatment steps can be carried out.
