[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] During the implementation of this embodiment, wastewater is injected into the device housing 1 through the feed pipe 4 by a water pump. At this time, by operating the control panel 3, the wastewater is separated and filtered through the separation component 5, so that the debris in the wastewater is retained, reducing the burden of subsequent oil removal. The filtered wastewater is then passed through the oil removal component 6 to remove the oil in the wastewater for the first time by combining air injection and gravity, and then air is continuously introduced into the wastewater. Under artificial oxygenation conditions, the sewage and various microbial communities are continuously mixed and cultured to form activated sludge, and the biological coagulation, adsorption and oxidation effects of the activated sludge are used to decompose and remove organic pollutants in the sewage, thereby treating the oil in the wastewater.

[0035] The control panel 3 mentioned above is a mature control technology means and equipment in the prior art. In this solution, its control function is utilized, and its connection method, structure and principle are not further explained.

[0036] Specifically, in order to filter the debris in the wastewater, refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 In this embodiment, the separation component 5 includes three partition plates 51 which are linearly distributed and fixedly connected to the right part of the inner surface of the device shell 1, two collection frames 52 are movably connected to the inner surface of the device shell 1, a separation mechanism 55 is provided on the inner surface of the device shell 1, a pushing mechanism 56 is commonly provided at the front and rear of the inner surface of the device shell 1 above the partition plate 1 51, and a partition plate 2 54 is commonly fixedly connected to the left side of the front and the right side of the rear of the inner surface of the device shell 1.

[0037] For further information, see Figure 3 , Figure 4 and Figure 5In this embodiment, the separation mechanism 55 includes a rectangular frame 551 fixedly connected to the left end of the upper partition 51 and the inner surface of the device housing 1, a solenoid valve tube 552 is fixedly connected to the lower part of the inner surface of the rectangular frame 551, a filter screen 553 is fixedly connected to the upper end of the rectangular frame 551, a slide groove 554 is opened on the upper part of the inner surface of the device housing 1, and a threaded rod 556 is rotatably connected to the left end of the device housing 1 and extends to the inner surface of the slide groove 554, and the outer surface of the threaded rod 556 is threadedly connected to the slide groove 554. A groove plate 555 is slidably connected to the left end of the device housing 1, and a double-axis motor 557 is fixedly connected to the left end of the double-axis motor 557. The output end of the left end of the double-axis motor 557 is fixedly connected to a rotating rod 558 through a coupling. The outer surface of the rotating rod 558 and the outer surface of the threaded rod 556 are jointly fixedly connected to a pulley set 559. A plurality of springs 5510 are linearly distributed and fixedly connected to the upper part of the inner surface of the groove plate 555. The lower ends of the plurality of springs 5510 are jointly fixedly connected to a push plate 5511 that is tightly attached to the upper end of the filter screen 553.

[0038] During the implementation process, the wastewater extracted by the water pump will retain the debris in the wastewater at the upper end of the filter screen 553 under the action of the filter screen 553, and then the left end output end of the dual-axis motor 557 is started to drive the threaded rod 556 to rotate under the action of the pulley group 559, and the groove plate 555 is driven to move to the right under the action of the threaded connection, and the push plate 5511 is always close to the upper end of the filter screen 553 under the action of the spring 5510. The push plate 5511 can push the debris retained on the filter screen 553, and the filtered wastewater will fall into the rectangular frame 551 under the action of gravity. The wastewater can be adjusted in the rectangular frame 551 to realize the separation operation of the debris in the wastewater, thereby reducing the subsequent burden of wastewater oil removal.

[0039] The pulley assembly 559 mentioned above is composed of two pulleys and a belt.

[0040] For further information, see Figure 4 and Figure 6 In this embodiment, the pushing mechanism 56 includes a fixing plate 561 fixedly connected to the front and rear of the inner surface of the device housing 1, a spring telescopic rod 562 is symmetrically fixedly connected to the left end of the fixing plate 561, a rectangular plate 563 is fixedly connected to the left ends of the two spring telescopic rods 562, and a round rod 564 is fixedly connected to the middle of the right end of the groove plate 555.

[0041] As can be seen from the above, when the push plate 5511 moves to the right, it will scrape the debris trapped in the filter screen 553 and move it to the right. Then the round rod 564 will gradually squeeze the rectangular plate 563 to move to the right, so that the spring telescopic rod 562 is compressed, and the scraped debris will enter the collection frame 52 located at the upper part under the action of gravity. The collection frame 52 can be taken out to deal with the debris in the collection frame 52.

[0042] Embodiment 2: Based on Embodiment 1, this embodiment adds an oil removal component 6 for removing grease from wastewater, thereby achieving the purpose of removing grease from wastewater.

[0043] Specifically, in order to remove grease from wastewater, refer to Figure 3 , Figure 4 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 In this embodiment, the oil removal component 6 includes a rectangular frame 2 61 fixedly connected to the inner surface of the device shell 1, a rectangular frame 3 62 is fixedly connected to the inner surface of the device shell 1 below the rectangular frame 2 61, an oil scraping mechanism 63 is arranged on the inner surface of the device shell 1 above the rectangular frame 2 61, guide grooves 64 are symmetrically opened at the front and rear of the inner surface of the device shell 1, and the inner surfaces of the two guide grooves 64 are both provided with blocking mechanisms 65, an air injection mechanism 66 is arranged on the inner surface of the rectangular frame 2 61, a stirring mechanism 67 is arranged on the inner surface of the rectangular frame 3 62, a collecting mechanism 68 is arranged at the lower part of the inner surface of the device shell 1, and a partition 3 69 is fixedly connected to the left ends of the middle and lower partitions 1 51.

[0044] For further information, see Figure 3 , Figure 4 and Figure 7 In this embodiment, the oil scraping mechanism 63 includes a reciprocating screw rod 632 that penetrates the left end of the device housing 1 and extends to the inner surface of the device housing 1 and is rotatably connected. The right end output end of the dual-axis motor 557 is fixedly connected to the rotating rod 2 631 through a coupling. The left part of the outer surface of the reciprocating screw rod 632 is fixedly connected to a one-way bearing 1 633 that is fixedly connected to the rotating rod 2 631. The outer surface of the reciprocating screw rod 632 is slidably connected to a slider 634. The inner surface of the slider 634 is slidably connected to a round rod 2 that is slidably connected to the inner surface of the guide groove 64. 635, a concave frame 637 is fixedly connected to the lower end of the second round rod 635, a groove scraper 638 is rotatably connected to the inner surface of the concave frame 637, an elastic sheet 639 is fixedly connected to the left end of the concave frame 637 and the left end of the groove scraper 638, a blocking rod 6310 is fixedly connected to the rear part of the inner surface of the device shell 1 above the lower collecting frame 52, and a spring 636 is symmetrically sleeved on the outer surface of the second round rod 635, and the two ends of the two springs 636 are respectively fixedly connected to the upper end of the concave frame 637 and the lower end of the slider 634.

[0045] For further information, see Figure 3 and Figure 8In this embodiment, the two blocking mechanisms 65 include a fixed rod 651 fixedly connected to the intersection of the inner surface of the guide groove 64, and the outer surfaces of the two fixed rods 651 are fixedly connected to coil springs 652, and the ends of the two coil springs 652 away from the fixed rod 651 are fixedly connected to a blocking plate 653 rotatably connected to the fixed rod 651.

[0046] For further information, see Figure 4 and Fig. 9 In this embodiment, the gas injection mechanism 66 includes a fan 661 fixedly connected to the upper end of the lower partition 51, the output end of the fan 661 passes through and extends to the inner surface of the rectangular frame 61 and is fixedly connected to a gas injection pipe 662, the lower part of the inner surface of the rectangular frame 61 is fixedly connected to a solenoid valve pipe 665, three ventilation pipes 663 connected to the inner surface of the gas injection pipe 662 are linearly distributed and fixedly connected on the outer surface of the gas injection pipe 662, a ventilation pipe 667 connected to the inner surface of the gas injection pipe 662 is fixedly connected to the left part of the outer surface of the gas injection pipe 662, and a control valve 666 is fixedly installed at the intersection of the outer surface of the gas injection pipe 662 and the outer surface of the ventilation pipe 667.

[0047] During the implementation process, the wastewater collected in the rectangular frame 551, after being properly adjusted, falls into the rectangular frame 61 through the electromagnetic valve pipe 552. Due to the different gravity of the oil and water in the wastewater, the oil will float above the water. At this time, the fan 661 is started, so that the fan 661 can draw air into the air injection pipe 662, and then enter the ventilation pipe 663, so that the gas can form a large number of fine bubbles. These bubbles can adhere to and carry the oil droplets in the wastewater to the water surface, thereby realizing oil-water separation. Due to the strong buoyancy of the bubbles, the oil droplets can quickly float up and gather on the water surface. Then, the right end output end of the dual-axis motor 557 is started to drive the rotating rod 631 to rotate, and the reciprocating screw 632 will be driven to rotate under the action of the one-way bearing 633. Since the slider 634 is slidably connected to the reciprocating screw 632, the slider 634 drives the round rod 635 to move on the inner surface of the guide groove 64. When the second round rod 635 moves to the right, the groove scraper 638 can scrape the grease floating on the water surface and collect it in the inner cavity of the groove scraper 638. When the second round rod 635 moves to the intersection of the guide groove 64, the second round rod 635 will push the blocking plate 653 to the right, so that the blocking plate 653 drives the coil spring 652 to deform. The second round rod 635 will continue to move to the right and drive the groove scraper 638 to move upward. The extrusion spring 636 is in a compressed state. The groove scraper 638 can leave the rectangular frame 61. The blocking plate 653 will reset under the deformation reaction of the coil spring 652. When the second round rod 635 moves to the rightmost side of the guide groove 64, the groove scraper 638 will be blocked by the blocking rod 6310 and rotate on the inner surface of the concave frame 637, and the elastic sheet 639 will be deformed, so that the grease retained in the groove scraper 638 can fall into the collection frame 52 at the bottom under the action of gravity.

[0048] Secondly, under the action of the reciprocating screw 632, the slider 634 will move to the left, and under the action of the blocking plate 653, the round rod 635 will move to the top of the inner surface of the guide groove 64, so that the groove scraper 638 is away from the liquid surface of the wastewater. When moving to the left side of the guide groove 64, the round rod 635 will be reset under the compression reaction of the spring 2 636. At the same time, the groove scraper 638 will once again enter below the liquid surface to scrape the oil in the wastewater again, thereby realizing the first separation operation of grease and water.

[0049] The reciprocating screw 632 and the slider 634 mentioned above constitute a ball screw mechanism in the prior art.

[0050] For further information, see Figure 4 and Fig.10In this embodiment, the stirring mechanism 67 includes a stirring rod 672 which is rotatably connected to the ventilation pipe 2 667 and extends to the right end of the rectangular frame 3 62 through the left end of the device housing 1. The outer surface of the rotating rod 2 631 is fixedly connected to a one-way bearing 2 671. The outer surface of the one-way bearing 2 671 and the left part of the outer surface of the stirring rod 672 are jointly fixedly connected to a pulley group 2 673. A plurality of ventilation holes 674 are arranged in an annular manner on the outer surface of the stirring rod 672. The lower part of the inner surface of the rectangular frame 3 62 is fixedly connected to a solenoid valve pipe 3 675.

[0051] During the implementation process, the wastewater that has undergone the first degreasing falls into the rectangular frame three 62 through the action of the electromagnetic valve pipe two 665. At this time, the right end output end of the dual-axis motor 557 is started to drive the rotating rod two 631 to rotate through the coupling, and the stirring rod 672 is driven to rotate under the action of the one-way bearing two 671 and the pulley group two 673. Then, the fan 661 is started to allow oxygen to enter the stirring rod 672 under the action of the control valve one 666 and the ventilation pipe two 667, and the oxygen is injected into the wastewater through the ventilation hole 674, so that the sewage and various microbial communities are continuously mixed and cultured to form activated sludge, and the biological coagulation, adsorption and oxidation effects of the activated sludge are used to decompose and remove organic pollutants in the sewage, thereby achieving the second degreasing.

[0056] During the implementation process, the wastewater after the second oil removal will fall into the T-shaped frame 681 under the action of the solenoid valve pipe three 675. The wastewater can be kept at a constant temperature through the heating plate 682, so that the metabolic activity of microorganisms is accelerated, the biochemical reaction rate is increased, and it is beneficial to the degradation of pollutants. In the T-shaped frame 681, gravity is used to make the sludge particles settle to the bottom in the static or low-speed flowing mixed liquid to achieve mud and water separation. At the same time, the microorganisms and organic matter in the activated sludge form floccules during the aeration process. These floccules have good sedimentation performance, so that the activated sludge is concentrated on the lower part of the inner surface of the T-shaped frame 681. Subsequently, the purified water can be discharged through the overflow pipe 687. At the same time, when the wastewater is treated again, the sludge pump 683 can be started at this time to make the activated sludge enter the connecting pipe two 685 through the connecting pipe one 684 and the control valve two 686, and the reflux activated sludge is sent back to the solenoid valve pipe two 665 and mixed with the sewage, thereby improving the efficiency of wastewater oil removal.

[0057] Secondly, the excess sludge in the T-shaped frame 681 can be pumped into the connecting pipe 684 through the sludge pump 683 and discharged from the device housing 1.

[0058] The control valve 1 666 and the control valve 2 686 mentioned above are both mature control technology means and equipment in the prior art. In this scheme, they are used to control the flow direction of semi-fluid and air, and their structure and principle are not further explained.

[0059] The dual-axis motor 557 mentioned above is a mature driving technology device in the prior art, and is a mature driving technology means in the prior art. In this scheme, it is used to rotate independently on both sides, and the number of positive and negative rotations on both sides can be adjusted and controlled separately, and it can stop in time after rotating to the set number of circles.

[0060] The heating plate 682 mentioned above is a mature heating technology means and equipment in the prior art. In this solution, its heating function is utilized, and its structure and principle are not further elaborated.

[0061] Working process: When in use, the separation mechanism 55 and the pushing mechanism 56 cooperate to filter and collect the debris in the wastewater, and then the oil in the wastewater floats on the water surface under the action of gravity and the gas injection mechanism 66. The oil scraping mechanism 63 and the blocking mechanism 65 cooperate to treat the oil floating on the water surface for the first time, and then the stirring mechanism 67 and the gas injection mechanism 66 cooperate to use microorganisms to produce activated sludge to remove the oil in the wastewater for the second time. Finally, the wastewater is purified and separated under the action of the collecting mechanism 68.
