However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1: As Figure 1 - Figure 5 As shown, this utility model provides a technical solution: an oily wastewater separation and recycling treatment device, including a separation box 1, an oil-water separation frame 2 fixedly connected to the inner side of the separation box 1, a square groove 3 opened at the top of the separation box 1, and a slot 4 opened at the bottom of the square groove 3, the slot 4 communicating with the oil-water separation frame 2, a filter plate 5 inserted inside the slot 4, a fixing plate 6 fixedly connected to the top of the filter plate 5, the fixing plate 6 being located inside the square groove 3, and the filter plate 5 cooperating with several sets of fixing components 7 through the fixing plate 6. The separation box 1 is fixedly connected. The fixing assembly 7 includes a first retaining seat 701, a second retaining seat 702, and a retaining block 703. The first retaining seat 701 and the second retaining seat 702 are located at both ends of the retaining block 703 and are fixedly connected to the top of the separation box 1. The bottom of the retaining block 703 abuts against the top surface of the fixing plate 6. The retaining block 703 is internally slidably connected with a first retaining pin 704 and a second retaining pin 706. A spring 705 is fixedly connected between the first retaining pin 704 and the second retaining pin 706. The end of the second locking pin 706 away from the spring 705 is inserted into the interior of the first locking seat 701 and the second locking seat 702. The tops of the first locking pin 704 and the second locking pin 706 are fixedly connected to the first pushing plate 707 and the second pushing plate 708. Limiting plates 30 are fixedly connected to both sides of the first locking seat 701 and the second locking seat 702. The two sides of the locking block 703 are located between the limiting plates 30. A sealing ring 26 is provided between the bottom of the square groove 3 and the fixing plate 6. The first pushing plate 707 and the second pushing plate 708 are fixedly connected to the first pushing plate 704 and the second pushing plate 708. The push plate 708 has anti-slip protrusions 31 on the side that comes into contact with fingers. The side of the separation box 1 is fixedly connected to a water inlet pipe 8 and an oil drain pipe 9. The water inlet pipe 8 and the oil drain pipe 9 are connected to the oil-water separation frame 2, and the water inlet pipe 8 is located above the oil drain pipe 9. The other side of the separation box 1 is fixedly connected to a drain pipe 16. The water inlet pipe 8, the oil drain pipe 9 and the drain pipe 16 are respectively equipped with a second valve 27, a third valve 28 and a fourth valve 29. The four corners of the bottom of the separation box 1 are fixedly connected to casters 17.

[0027] The beneficial effects achieved in this embodiment 1 are as follows: Through the cooperation of the fixing plate 6 and the fixing assembly 7 at the top of the filter plate 5, the first retaining bracket 701 and the second retaining bracket 702 in the fixing assembly 7 are used to fix it to the top of the separation box 1. Furthermore, the first retaining pin 704 and the second retaining pin 706 in the retaining block 703 are inserted into the first retaining bracket 701 and the second retaining bracket 702 under the action of the spring 705, thus fixing the filter plate 5. When it is necessary to disassemble the filter plate 5, the first extrusion plate 707 and the second extrusion plate 708 with anti-slip protrusions 31 are pressed. 08. The first locking pin 704 and the second locking pin 706 overcome the elastic force of the spring 705 and are pulled out from the first locking seat 701 and the second locking seat 702, which allows for convenient disassembly of the filter plate 5. This greatly improves the ease of disassembly of the filter plate 5, reduces the manpower and time costs of maintaining the filter plate 5, and ensures that the device can operate efficiently and continuously. The limiting plates 30 provided on both sides of the first locking seat 701 and the second locking seat 702 limit the locking block 703, so that the locking block 703 is engaged with the first locking seat 701 and the second locking seat 702. The device quickly aligns the two ends of the card block 703 with the first card holder 701 and the second card holder 702, preventing misalignment that could affect the fixing efficiency. The sealing ring 26 between the bottom of the square groove 3 and the fixing plate 6 effectively prevents wastewater from leaking out of the gaps, ensuring the device's airtightness and preventing wastewater seepage from affecting the normal use of the device and the surrounding environment. The first extrusion plate 707 and the second extrusion plate 708 have anti-slip protrusions 31 on the sides that come into contact with fingers, facilitating force application and preventing hand slippage. The water inlet pipe 8, oil outlet pipe 9, and drain pipe 16 are connected to the side of the separation box 1, and are respectively equipped with a second valve 27, a third valve 28, and a fourth valve 29, which can conveniently control the inflow of oily wastewater, the discharge of separated oil, and the discharge of treated water, achieving orderly operation of each link and facilitating flexible adjustment according to the actual processing situation. The universal wheels 17 fixedly connected to the four corners of the bottom of the separation box 1 give the entire device good mobility, making it easy to move the device to different positions according to usage needs, improving the device's flexibility and applicability.

[0028] Example 2: As Figure 2 - Figure 4As shown, a disinfectant storage tank 10 is installed on the top of the separation box 1. The bottom of the disinfectant storage tank 10 is connected to the separation box 1 through a feeding pipe 11. A first valve 12 is installed on the feeding pipe 11. A fixed base 20 is fixedly connected to the top of the separation box 1. A bearing 21 is fixedly connected inside the fixed base 20. A column 22 is fixedly connected to the inner side of the bearing 21. A stirring rod 23 is fixedly connected to a section of the column 22 located inside the separation box 1. A crank handle 24 is fixedly connected to the top of the column 22. A first observation window 13 is embedded in the front of the separation box 1. A second observation window 14 is embedded in the side of the separation box 1. The second observation window 14 corresponds to the oil-water separation frame 2. A third observation window 15 is embedded in the outer wall of the disinfectant storage tank 10. A handle 18 is fixedly connected to the side of the separation box 1. A first handle sleeve 19 and a second handle sleeve 25 are respectively fitted on the gripping parts of the handle 18 and the crank handle 24. Both the first handle sleeve 19 and the second handle sleeve 25 are made of elastic rubber.

[0029] The beneficial effects achieved in this embodiment 2 are as follows: By setting a disinfectant storage tank 10 on the top of the separation tank 1 and connecting it to the separation tank 1 via a feeding pipe 11, and by setting a first valve 12 on the feeding pipe 11, it is possible to conveniently store and add disinfectant to the separation tank 1 as needed, which facilitates the disinfection and other related treatments of oily wastewater, and improves the versatility of the device's wastewater treatment functions. The bearing 21 in the fixed base 20 cooperates with the column 22. The section of the column 22 located in the separation tank 1 is connected to the stirring rod 23, and the top is connected to the crank handle 24. Turning the crank handle 24 can drive the stirring rod 23 to rotate in the separation tank 1, stirring the added disinfectant and wastewater, so that the disinfectant can be quickly and evenly mixed with the wastewater. To enhance the effectiveness of disinfection and other treatments and ensure more thorough and effective wastewater treatment, the separation box 1 features a first observation window 13 embedded in the front, a second observation window 14 embedded in the side, and a third observation window 15 embedded in the outer wall of the disinfectant storage tank 10. This allows operators to easily observe the wastewater treatment status inside the device, the separation status within the oil-water separation frame 2, and the remaining amount of disinfectant, facilitating timely monitoring of the treatment process and making corresponding operational adjustments. The handle 18 and the crank 24 are respectively fitted with a first handle sleeve 19 and a second handle sleeve 25 made of elastic rubber, increasing the operator's grip comfort and providing anti-slip properties, making operation more stable and convenient, and improving the user experience.

[0030] The working principle of this embodiment is as follows: When using this oily wastewater separation and recycling device, firstly, the second valve 27 is opened through the water inlet pipe 8 on the side of the separation tank 1 to introduce the oily wastewater into the separation tank 1. The wastewater flows into the oil-water separation frame 2 fixedly connected to the inner side. At this time, the filter plate 5 located in the oil-water separation frame 2 plays its role. When the wastewater passes through the filter plate 5, due to the characteristics of the filter plate 5 itself (such as oleophilic and hydrophobic properties, which can be determined according to the actual material and function of the filter plate 5), the oil is trapped on one side of the filter plate 5 and separated from the water, while the water continues to flow downward. When it is necessary to collect the separated oil, the third valve 28 on the oil drain pipe 9 is opened, and the separated oil is discharged along the oil drain pipe 9 for subsequent recycling. When wastewater needs to be disinfected and sterilized, first open the first valve 12 on the bottom feed pipe 11 of the disinfectant storage tank 10 to allow the disinfectant to flow into the separation tank 1. Then, the operator holds the crank handle 24 and rotates it. The crank handle 24 drives the column 22 to rotate around the bearing 21 in the fixed seat 20, thereby causing the stirring rod 23 on the column 22 to stir the wastewater in the separation tank 1. Under the stirring action, the disinfectant is quickly and evenly mixed with the wastewater, achieving a better disinfection and sterilization effect. The treated water can then be discharged from the drain pipe 16 by opening the fourth valve 29 on the drain pipe 16. Throughout the process, the operator can observe the overall wastewater treatment status in the device through the first observation window 13 and the second observation window 14. The observation window 14 shows the oil-water separation status within the oil-water separation frame 2, and the third observation window 15 shows the remaining amount of disinfectant in the disinfectant storage tank 10. This allows for timely adjustments based on the observations. If the device needs to be moved, the handle 18 and the casters 17 at the four corners of the bottom of the separation box 1 can be used to easily move the device. When the filter plate 5 needs to be removed for cleaning or replacement, the operator presses the first push plate 707 and the second push plate 708. The pressure applied to the first push plate 707 and the second push plate 708 causes the first locking pin 704 and the second locking pin 706 to move upwards against the spring force of the spring 705, causing the first locking pin 704 and the second locking pin 706 to move from the first locking seat 701 and the second locking seat 706. Pull the filter plate 5 out of the slot 4, then remove the locking block 703 to release the fixing plate 6. At this point, the filter plate 5 can be easily pulled out for cleaning or replacement. To reinstall the filter plate 5, insert it into the slot 4, placing the fixing plate 6 in the square groove 3. Then press the first push plate 707 and the second push plate 708, and place the locking block 703 between the first and second slots 701 and 702, locking it between the limiting plates 30 on both sides of the first and second slots 701 and 702. Align the first locking pin 704 and the second locking pin 706 with the first and second slots 701 and 702. Release the pressed first push plate 707 and the second push plate 708; under the elastic force of the spring 705...The first locking pin 704 and the second locking pin 706 will re-insert into the first locking seat 701 and the second locking seat 702, completing the fixed installation of the filter plate 5, and the device can then continue to operate normally.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
