[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] As Figures 1 to 8 shown, the present invention provides an environment-friendly petrochemical waste liquid treatment and recycling device, including an oil filter barrel 1. The bottom end of the oil filter barrel 1 is fixedly connected with a sedimentation tank 2. The rear side of the inner surface of the sedimentation tank 2 is movably connected with a push plate 3. The rear surface of the push plate 3 is fixedly connected with a long rod 4. The rear end of the long rod 4 penetrates through the sedimentation tank 2 and extends to the rear side of the sedimentation tank 2. The inner surface of the rear side of the long rod 4 is fixedly sleeved with a connecting column 5. The lower surface of the sedimentation tank 2 is fixedly installed with a first motor 6. The other end of the output shaft of the first motor 6 is fixedly sleeved with a first circular shaft 7. The outer surface of the first circular shaft 7 is fixedly sleeved with a driving rod 8. The inner surface of the driving rod 8 and the outer surface of the connecting column 5 are movably connected.

[0028] When the first motor 6 operates to make the first circular shaft 7 and the driving rod 8 start to rotate, since the connecting column 5 and the inner surface of the driving rod 8 are connected to each other, the rotation of the driving rod 8 will drive the connecting column 5, so that the connecting column 5, the long rod 4 and the push plate 3 as a whole start to move along the inner surface of the sedimentation tank 2.

[0029] Among them, the right side of the inner surface of the sedimentation tank 2 is fixedly connected with a filter plate 27. The right end of the filter plate 27 penetrates through the sedimentation tank 2 and extends to the right side of the sedimentation tank 2. The right surface of the sedimentation tank 2 is fixedly connected with a water outlet pipe 28 located on the right side of the filter plate 27. The right side of the upper surface of the sedimentation tank 2 is fixedly connected with a feeding port 31 located on the right side of the oil filter barrel 1. The bottom end of the feeding port 31 penetrates through the sedimentation tank 2 and extends to the inside of the sedimentation tank 2.

[0030] The filter plate 27 functions to prevent the sludge inside the sedimentation tank 2 from entering the inside of the water outlet pipe 28.

[0031] Among them, a closing plate 9 is movably connected to the front surface of the sedimentation tank 2. A bolt 10 is movably connected to the front surface of the closing plate 9.

The outer surface of the bolt 10 is threadedly sleeved with the inner surface of the sedimentation tank 2.

[0032] The design of the closing plate 9 and the bolt 10 enables the closing plate 9 to be disassembled.

[0034] When the second motor 17 operates, the second circular shaft 18 and the stirring disc 19 will start to rotate, and the rotation of the stirring disc 19 will drive the oil-water mixture inside the sedimentation tank 2, causing the oil-water mixture to start rotating at high speed.

The lower surface of the installation ring 15 is movably connected to the upper surface of the installation plate 14.

The inner surface of the oil-water separation circular sieve 16 is movably connected to the outer surface of the installation plate 14.

[0036] The inner surface of the oil-water separation circular sieve 16 is covered with an oil-water separation membrane. The water inside the oil-water separation circular sieve 16 can enter the outside of the oil-water separation circular sieve 16 through the oil-water separation membrane, while the macromolecular oil inside the oil-water separation circular sieve 16 will be blocked inside the oil-water separation circular sieve 16.

[0037] Among them, clamping blocks 20 are movably connected to both the front and rear sides of the upper surface of the installation ring 15. The number of the clamping blocks 20 is two. The outer surfaces of the left and right sides of the two clamping blocks 20 are movably connected to first limiting plates 21. The lower surface of the first limiting plates 21 is fixedly connected to the upper surface of the oil filter barrel 1.

[0038] The design of the first limiting plates 21 functions to limit the movement of the clamping blocks 20.

[0039] Among them, a fixed plate 22 is fixedly connected to the top end on the right side of the outer surface of the oil filter barrel 1. An air cylinder 23 is fixedly installed on the upper surface of the fixed plate 22. The left end of the air cylinder 23 is fixedly connected to a moving plate 24. The outer surfaces on the front and rear sides of the moving plate 24 are movably connected to second limiting plates 25 respectively. The lower surfaces of the second limiting plates 25 are fixedly connected to the upper surfaces of the oil filter barrel 1 and the fixed plate 22 respectively.

[0040] When the air cylinder 23 operates, the moving plate 24 will start to move.

[0041] Among them, connecting rods 26 are hinged to the front and rear sides of the upper surface of the moving plate 24. The number of the connecting rods 26 is two. The other ends of the two connecting rods 26 are respectively hinged to the upper surfaces of two clamping blocks 20.

[0042] The movement of the moving plate 24 will drive the connecting rods 26 to start rotating. At the same time, the other ends of the connecting rods 26 will drive the clamping blocks 20, causing the clamping blocks 20 to move.

[0043] Among them, a liquid valve 29 is fixedly installed in the middle of the upper surface of the circular plate 12. The bottom end of the liquid valve 29 penetrates through the circular plate 12 and extends below the circular plate 12 and is fixedly connected to an oil outlet pipe 30. The outer end of the oil outlet pipe 30 penetrates through the oil filter barrel 1 and extends to the outside of the oil filter barrel 1.

[0044] When the circular plate 12 is opened, the waste oil inside the oil-water separation circular sieve 16 will move to the outside of the whole oil filter barrel 1 through the oil outlet pipe 30.

[0045] The working principle and usage process of the present utility model:

[0046] When a large amount of sludge accumulates in the sedimentation tank 2, the operator first removes the closing plate 9 and the bolts 10 and then starts the first motor 6. As the first motor 6 operates, the first circular shaft 7 and the driving rod 8 will start to rotate. At this time, the inner surface of the driving rod 8 will drive the connecting column 5 during the rotation process, causing the connecting column 5 and the pushing plate 3 as a whole to start moving forward along the inner surface of the sedimentation tank 2. Finally, as the pushing plate 3 moves, the sludge inside the sedimentation tank 2 will be pushed by the pushing plate 3 to the outside of the sedimentation tank 2.

[0047] When the operator needs to replace the oil-water separation membrane on the inner surface of the oil-water separation round sieve 16, the operator starts the air cylinder 23. As the air cylinder 23 operates, the moving plate 24 will move along the inner surface of the second limiting plate 25 towards the oil filtering barrel 1. At this time, the movement of the moving plate 24 will cause the two connecting rods 26 to start rotating, and the other ends of the connecting rods 26 will drive the clamping blocks 20 at this time, causing the two clamping blocks 20 to move away from each other along the inner surface of the first limiting plate 21. Finally, when the two clamping blocks 20 no longer contact the mounting ring 15, the operator can directly extract the entire mounting ring 15 to achieve the replacement of the oil-water separation membrane.
