Description

Technical Field

[0001] This utility model belongs to the field of oil-water separation technology, specifically a two-stage separation type oil-water separator. Background Technology

[0002] Two-stage oil-water separators are important tools for treating oily wastewater. The oily wastewater first enters the primary separation stage, where large oil droplets are intercepted and coalesced by special filters or coalescing filter elements, thus initially separating the oil and water. Subsequently, the liquid flows into the secondary separation zone, where finer materials, such as high-precision filter elements and adsorption materials, are used to capture the remaining fine oil droplets, making the water purer.

[0003] The existing two-stage oil-water separators still have the following shortcomings: the filter tank of the existing two-stage oil-water separator is difficult to clean, oil stains easily adhere to the inner wall of the filter tank, the cleaning process is time-consuming and labor-intensive, increasing the operation and maintenance costs, and conventional cleaning methods are not effective, which can easily lead to oil stains remaining. Utility Model Content

[0006] As a further embodiment of this utility model: the spraying assembly includes a liquid storage cylinder and a bidirectional threaded rod. The liquid storage cylinder is fixedly connected to the top of the filter tank. The bidirectional threaded rod is coaxially fixedly connected to the output end of the servo motor. A piston plate is slidably and sealingly connected to the inner wall of the liquid storage cylinder. A connecting rod is fixedly connected to the top of the piston plate.

A gear is coaxially fixedly connected to the bidirectional threaded rod. The bottom of the bidirectional threaded rod is rotatably connected to the filter tank. Drain pipes are connected to both sides of the liquid storage cylinder that are far apart from each other. One end of each drain pipe passes through the filter tank and is fixedly connected to it. A nozzle is connected to one end of each drain pipe. A replenishment pipe is connected to one side of the liquid storage cylinder. A one-way valve is provided on both the replenishment pipe and the drain pipe.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figures 1-3 As shown, this utility model provides a technical solution:

[0020] A two-stage oil-water separator includes a filter tank 1, a support frame 2 fixedly connected to the top of the filter tank 1, a servo motor 3 fixedly connected to the top of the support frame 2, the output end of the servo motor 3 passing through the support frame 2 and rotatably connected thereto, a spraying component is provided on the top of the filter tank 1, a cleaning component is provided on the filter tank 1, an inlet 4 and an oil outlet 5 are respectively connected to the filter tank 1, a separation tank 6 is connected to the bottom of the filter tank 1, and a drain pipe 7 is connected to the bottom of the separation tank 6. Oil and water enter the filter tank 1 through the inlet 4, the product after primary filtration enters the separation tank 6 for secondary filtration, and water is discharged through the drain pipe 7. When the filter tank 1 needs to be cleaned, the servo motor 3 is started, the servo motor 3 drives the spraying component to work, and the spraying component simultaneously drives the cleaning component to work.

[0021] The spraying assembly includes a storage cylinder 8 and a bidirectional threaded rod 9. The storage cylinder 8 is fixedly connected to the top of the filter tank 1. The bidirectional threaded rod 9 is coaxially fixedly connected to the output end of the servo motor 3. A piston plate 10 is slidably connected to the inner wall of the storage cylinder 8. A connecting rod 11 is fixedly connected to the top of the piston plate 10. A lifting plate 12 is threadedly connected to the bidirectional threaded rod 9. The top of the connecting rod 11 is fixedly connected to the lifting plate 12. A gear 13 is coaxially fixedly connected to the bidirectional threaded rod 9. The bottom of the bidirectional threaded rod 9 is rotatably connected to the filter tank 1. Drain pipes 14 are connected to both sides of the storage cylinder 8 that are far apart from each other. One end of each drain pipe 14 passes through the filter tank 1 and is fixedly connected to it. A nozzle is connected to one end of each drain pipe 14. A replenishment pipe 15 is connected to one side of the storage cylinder 8. Both the drain pipe 14 and the servo motor 3 are equipped with a one-way valve. The output end of the servo motor 3 drives the bidirectional threaded rod 9 to rotate. The gear 13 rotates with the bidirectional threaded rod 9. The bidirectional threaded rod 9 first drives the lifting plate 12 to descend. The lifting plate 12 drives the piston plate 10 to slide on the inner wall of the storage tank 8 through the connecting rod 11. The piston plate 10 pushes the cleaning liquid in the storage tank 8 into the drain pipe 14. The cleaning liquid in the drain pipe 14 is sprayed out through the nozzle, quickly covering all corners of the inner wall of the filter tank 1, powerfully breaking down stubborn oil stains and reducing the difficulty of cleaning. Subsequently, the bidirectional threaded rod 9 drives the lifting plate 12 to rise. The lifting plate 12 drives the piston plate 10 to rise through the connecting rod 11. The replenishment pipe 15 is connected to an external delivery pipe, so that the cleaning liquid is sucked into the storage tank 8 through the replenishment pipe 15, completing the replenishment.

[0022] A guide rod 16 is fixedly connected to the top of the filter tank 1. The top of the guide rod 16 passes through the lifting plate 12 and is slidably connected to it. The lifting plate 12 slides on the guide rod 16. The guide rod 16 can prevent the lifting plate 12 from rotating with the bidirectional threaded rod 9.

[0023] The cleaning assembly includes a rotating shaft 17, which is rotatably connected to the filter tank 1. A gear 2 18 is coaxially fixedly connected to the top of the rotating shaft 17, and the gear 2 18 meshes with the gear 1 13. A rotating rod 19 is coaxially fixedly connected to the bottom of the rotating shaft 17, and cleaning rollers 20 are rotatably connected to both ends of the rotating rod 19. A gear 3 21 is coaxially fixedly connected to the top of the cleaning roller 20. The gear 1 13 drives the rotating shaft 17 to rotate on the filter tank 1 through the gear 2 18 it meshes with. The rotating shaft 17 drives the rotating rod 19 to rotate, and the rotating rod 19 drives the cleaning roller 20 to revolve around the rotating shaft 17.

[0024] A gear ring 22 is fixedly connected to the inner wall of the filter tank 1. The gear ring 22 meshes with the gear 3 21. A fiber filter screen 23 is provided at the bottom of the filter tank 1. The gear 3 21 can rotate along the gear ring 22. The gear 3 21 drives the cleaning roller 20 to rotate. The fiber filter screen 23 can trap larger grease particles.

[0025] Multiple support columns are fixedly connected to the bottom of the filter tank 1. The support columns are used to support and stabilize the filter tank 1.

[0026] The working principle of this utility model is as follows:

[0027] Oil and water enter the filter tank 1 through the feed inlet 4. The fiber filter screen 23 can trap larger oil particles. The oil can be discharged through the oil outlet 5. The product after primary filtration enters the separation tank 6 for secondary filtration. The water is discharged through the drain pipe 7.

[0028] When the filter tank 1 needs to be cleaned, the servo motor 3 is started. The output end of the servo motor 3 drives the bidirectional threaded rod 9 to rotate. The gear 13 rotates with the bidirectional threaded rod 9. The bidirectional threaded rod 9 first drives the lifting plate 12 to slide down on the guide rod 16. The lifting plate 12 drives the piston plate 10 to slide on the inner wall of the storage tank 8 through the connecting rod 11. The piston plate 10 pushes the cleaning liquid in the storage tank 8 into the drain pipe 14. The cleaning liquid in the drain pipe 14 is sprayed out through the nozzle, quickly covering all corners of the inner wall of the filter tank 1, powerfully breaking down stubborn oil stains and reducing the difficulty of cleaning. Subsequently, the bidirectional threaded rod 9 drives the lifting plate 12 to rise. The lifting plate 12 drives the piston plate 10 to slide up on the guide rod 16 through the connecting rod 11. The replenishment pipe 15 is connected to the external delivery pipe, so that the cleaning liquid is sucked into the storage tank 8 through the replenishment pipe 15, completing the replenishment.

[0029] Meanwhile, gear 13 drives the rotating shaft 17 to rotate on the filter tank 1 through gear 2 18, which meshes with it. The rotating shaft 17 drives the rotating rod 19 to rotate, and the rotating rod 19 drives the cleaning roller 20 to revolve around the rotating shaft 17. Gear 3 21 can rotate along the gear ring 22. Gear 3 21 drives the cleaning roller 20 to rotate on its own axis, so that the cleaning roller 20 can accurately scrape and brush the stubborn oil stains in the filter tank 1. With the help of cleaning fluid, the decontamination effect is improved exponentially, greatly shortening the cleaning time and keeping the filter tank 1 in a highly efficient oil-water separation state.

[0030] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
