Description

Technical Field

[0001] This utility model relates to the field of oil-water mixture treatment technology, specifically to an oil-water separation device for oily waste liquid. Background Technology

[0002] The amount of oily waste liquid generated globally each year is countless. Whether it is industrial or domestic waste liquid, direct discharge will have an extremely adverse impact on water and soil environments, thus seriously damaging aquatic ecosystems. However, the cost of treating the waste liquid is too high if it is not discharged directly. Therefore, oil-water separation devices are needed to treat oily waste liquid.

[0003] However, most existing oil-water treatment devices for oily waste liquid use a static method, waiting for the oil and water to settle before the waste oil floats on the water surface and is discharged through a discharge device. This method is inefficient, and impurities in the oily waste liquid settle in the separation tank and cannot be discharged. Therefore, an oil-water separation device for oily waste liquid is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide an oil-water separation device for oily waste liquid. The device uses a liftable oil suction component installed inside the separation tank to suck up the oil from the oily waste liquid inside the separation tank. At the same time, a drainage filter component inside the drain pipe at the bottom of the separation tank filters impurities in the discharged wastewater, thereby solving the problems mentioned in the background art.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 This utility model provides a technical solution:

[0025] An oil-water separation device for oily waste liquid includes a separation box 1, a bracket 4 fixedly sleeved below the outer arc surface of the separation box 1, a drainage filter assembly 3 for filtering impurities is provided on the bottom surface of the separation box 1, and an oil suction assembly 5 for absorbing oil from the oily waste liquid inside the separation box 1 is also provided inside the separation box 1.

[0026] The oil-absorbing assembly 5 includes an oil-absorbing sponge 12 and a lifting frame 8. The oil-absorbing sponge 12 is respectively disposed on both sides of the lifting frame 8, and the lifting frame 8 is also threadedly connected to the lifting module. The two sets of oil-absorbing sponges 12 are symmetrically provided with protrusions 13 on their opposite sidewalls. Spring plungers 14 are respectively provided on both sides of the top surface of the protrusions 13. The sidewalls of the lifting frame 8 are symmetrically provided with through grooves 11. The oil-absorbing sponge 12 is inserted into the inside of the through grooves 11, and the top surface of the oil-absorbing sponge 12 is respectively provided with round holes 10. The inner wall of the round holes 10 is respectively engaged with the spring plungers 14.

[0027] The oil-absorbing sponge 12 is engaged with the through groove 11 on the side wall of the lifting frame 8 by a spring plunger 14. The lifting frame 8 is also threadedly connected to the lifting module. The oil-absorbing sponge 12 is made of polyurethane foam, which has good oil absorption effect and hydrophobic properties. This allows the lifting module to drive the lifting frame 8 to lift the oil-absorbing sponges 12 on both sides to absorb the oil in the oily waste liquid inside the separation box 1. After absorption, the oil-absorbing sponge 12 is lifted by the lifting module, making it easy for workers to disassemble it and squeeze out and collect the oil absorbed by the oil-absorbing sponge 12.

[0028] Each of the two sets of oil-absorbing sponges 12 has a handle 15 in the middle of its top surface. By providing the handle 15 in the middle of the top surface of the two sets of oil-absorbing sponges 12, workers can easily disassemble the oil-absorbing sponges 12 by holding the handle 15. This avoids workers holding the oil-absorbing sponge 12 body by hand, which may cause the oil absorbed inside the oil-absorbing sponge 12 to be squeezed out, resulting in environmental pollution.

[0029] The lifting module includes a rotary motor 6 and a threaded rod 7. The rotary motor 6 is fixedly installed on the bottom surface of the separation box 1.

The lifting frame 8 is sleeved on the outside of the threaded rod 7 and threadedly connected to the outer arc surface of the threaded rod 7.

[0030] By setting the lifting frame 8 to be sleeved on the outside of the threaded rod 7 and threadedly connected to the threaded rod 7, and the threaded rod 7 being keyed to the output shaft of the rotary motor 6, the threaded rod 7 can be rotated by starting the rotary motor 6, thereby causing the lifting frame 8 to rise and fall along the outer arc surface of the threaded rod 7, thereby driving the oil-absorbing sponge 12 to rise and fall.

[0031] Limiting blocks 9 are provided on both sides of the lifting frame 8, and limiting grooves 23 are symmetrically provided on the inner wall of the separation box 1. The limiting blocks 9 are slidably disposed inside the limiting grooves 23. Limiting blocks 9 are also provided on both sides of the lifting frame 8, and the limiting blocks 9 are slidably connected to the inner wall of the limiting grooves 23 opened on the inner wall of the separation box 1, so as to determine the direction of the lifting frame 8 when it is raised and lowered by the limiting blocks 9, thereby increasing the stability of the lifting frame 8 when it is raised and lowered.

[0032] The bottom surface of the separation box 1 is also provided with a liquid drain pipe 16. Hooks 18 are symmetrically provided on the outer arc surface of the bottom end of the liquid drain pipe 16. The drainage filter assembly 3 is located inside the liquid drain pipe 16 and is engaged with the hooks 18. The bottom surface of the separation box 1 is also provided with three sets of support legs 2.

[0033] Furthermore, a drain pipe 16 is provided through the bottom surface of the separation box 1, and a hook 18 is symmetrically provided on the outer arc surface of the bottom end of the drain pipe 16. The drain filter assembly 3 is located inside the drain pipe 16, and the hook 18 is engaged with the drain filter assembly 3 so as to fix the drain filter assembly 3 through the hook 18, which facilitates the worker to disassemble and clean the drain filter assembly 3 regularly.

[0034] The drainage filter assembly 3 includes an inner filter pipe 17, which is located inside the drain pipe 16. The bottom outer arc surface of the inner filter pipe 17 is symmetrically fixed with fixing plates 19. The surfaces of the two sets of fixing plates 19 are respectively rotatably mounted with rotating plates 20 via hinges. The rotating plates 20 are all L-shaped, and the side walls at the ends of the rotating plates 20 are provided with slots 21, which are respectively engaged with hooks 18.

[0035] The inner filter tube 17 is also equipped with a filter plate 22.

[0036] An internal filter pipe 17 is installed inside the lower liquid pipe 16, and a fixing plate 19 is symmetrically installed on the outer arc surface of the bottom end of the lower liquid pipe 16. The surface of the fixing plate 19 is equipped with a rotating plate 20 that is hinged. The rotating plates 20 are all L-shaped, and the side walls of the rotating plates 20 are respectively provided with slots 21. The slots 21 are engaged with hooks 18 to fix the internal filter pipe 17. At the same time, a filter plate 22 is installed inside the internal filter pipe 17 to filter the discharged wastewater so that the filtered wastewater can be collected and reused.
