Specific implementation mode

[0033] The present invention will be further described below in conjunction with the drawings and embodiments.

[0034] A centrifugal sewage treatment device, as Figures 1 - 10 shown, includes a centrifugal tank 1, a centrifugal mechanism 2 and an oil removal mechanism 3. The centrifugal mechanism 2 is provided on the centrifugal tank 1, and the oil removal mechanism 3 is provided between the centrifugal tank 1 and the centrifugal mechanism 2.

[0035] As Figure 1 and Figure 3 shown, the centrifugal mechanism 2 includes an upper cover 21, multiple layers of centrifugal filter cartridges 22, a first servo motor 23, a filter screen 24 and a water outlet hopper 25. The upper cover 21 is clamped on the upper side of the centrifugal tank 1. The first servo motor 23 is connected to the inner side of the lower part of the centrifugal tank 1. A multi-layer centrifugal filter cartridge 22 is connected to the output shaft of the first servo motor 23. The multi-layer centrifugal filter cartridge 22 is rotatably connected to the centrifugal tank 1. The water outlet hopper 25 is connected to the lower side of the centrifugal tank 1, and a filter screen 24 is connected inside the water outlet hopper 25.

[0036] As Figure 1 , Figure 4 and Figure 5 shown, the oil removal mechanism 3 includes a cylinder 31, a connecting piece 32, an annular frame 33, a support rod 34, a floating cylinder 35, a connecting rope 36 and a connecting pipe 37. Cylinders 31 are connected to both the front and rear sides of the centrifugal tank 1. Connecting pieces 32 are connected to the telescopic ends of the cylinders 31, and the connecting pieces 32 are both connected to the upper cover 21. Three annular frames 33 are placed inside the lower part of the multi-layer centrifugal filter cartridge 22. Two support rods 34 are connected to the upper sides of the annular frames 33, and the upper sides of the support rods 34 are both connected to the upper cover 21. A floating cylinder 35 is connected to the lower side of the middle part of the upper cover 21 through four connecting ropes 36. A connecting pipe 37 is connected to the upper side of the floating cylinder 35, and the connecting pipe 37 passes through the upper cover 21.

[0037] When using the present invention, first place the centrifugal tank 1 in the sewage treatment area, then connect the sewage pipe to the upper cover 21. After that, pass the sewage into the centrifugal tank 1 through the sewage pipe. Then start the first servo motor 23 to drive the multi-layer centrifugal filter cylinder 22 to rotate, generating a strong centrifugal force to separate the impurities from the liquid in the sewage. Impurities of different sizes are respectively intercepted in different areas of the multi-layer centrifugal filter cylinder 22, and the grease accumulates in the middle of the multi-layer centrifugal filter cylinder 22. The separated liquid enters the water outlet hopper 25 from the centrifugal tank 1 and is discharged after being filtered again by the filter screen 24. During sewage treatment, connect the connecting pipe 37 to an external oil suction pump. The floating cylinder 35 always floats on the upper side of the sewage. When the grease is separated from the liquid, start the oil suction pump so that the grease is sucked into the floating cylinder 35 and the connecting pipe 37 and discharged. Thus, it plays a role in being able to perform multi-stage filtration treatment on the sewage during centrifugation, and at the same time can remove the grease separated from the water, improving the sewage treatment effect. When stopping sewage treatment, start the cylinder 31 to push the connecting piece 32 and the upper cover 21 to move upward, so that the support rod 34 and the annular frame 33 move upward. At this time, the annular frame 33 scrapes the impurities on the multi-layer centrifugal filter cylinder 22, thus playing a role in being able to automatically clean the multi-layer centrifugal filter cylinder 22 and ensuring the filtration efficiency of the multi-layer centrifugal filter cylinder 22.

[0038] As Figure 1 , Figure 6 and Figure 7 shown, it further includes a feeding mechanism 4. The feeding mechanism 4 includes a second servo motor 41, a reciprocating lead screw 42, a guide rod 43, a lifting frame 44, a pressing plate 45, a material bucket 46, a feed pipe 47 and a closing component. The upper side of the rear part of the upper cover 21 is connected with a second servo motor 41. The output shaft of the second servo motor 41 is connected with a reciprocating lead screw 42. The upper side of the front part of the upper cover 21 is connected with a guide rod 43. The guide rod 43 is slidably connected with a lifting frame 44. The lifting frame 44 is threadedly connected with the reciprocating lead screw 42. The lower side of the lifting frame 44 is connected with four pressing plates 45. The upper cover 21 is connected with four material buckets 46. The pressing plates 45 are all slidably connected with the adjacent material buckets 46. The two material buckets 46 on the left are connected with a feed pipe 47 through a one-way valve. The two material buckets 46 on the right are also connected with a feed pipe 47 through a one-way valve. The upper cover 21 is provided with a closing component. The closing component includes a discharge frame 48, a fixing piece 49, a rotating plate 410 and a third torsion spring 411. The lower side of the upper cover 21 is connected with four discharge frames 48. The discharge frames 48 are located below the adjacent material buckets 46. The lower side of the upper cover 21 is connected with sixteen fixing pieces 49. A rotating plate 410 is rotatably connected between every two adjacent fixing pieces 49. The rotating plates 410 are all located below the adjacent discharge frames 48. A third torsion spring 411 is connected between each fixing piece 49 and the connected rotating plate 410.

[0039] Using the feeding mechanism 4 of this device, it is convenient to add chemicals to the sewage. Inject the chemicals from the feed pipe 47 into the material bucket 46. Then start the second servo motor 41 to drive the reciprocating lead screw 42 to rotate, causing the lifting frame 44 to move downward along the guide rod 43, pushing the pressing plate 45 downward to discharge the chemicals from the lower part of the material bucket 46 into the discharge frame 48, so that the chemicals push open the rotating plate 410 and the third torsion spring 411 deforms. When the discharge of the chemicals stops, the torsion spring returns to drive the rotating plate 410 to reset and close the discharge frame 48, thus playing the role of being able to conveniently add chemicals to the sewage and improve the sewage treatment efficiency.

[0040] As Figure 1 and Figure 8 shown, it also includes a support mechanism 5. The support mechanism 5 includes a support frame 51, a shock absorber 52, a base 53 and a support leg rod 54. Five support frames 51 are connected to the lower part of the centrifugal tank 1. Shock absorbers 52 are rotatably connected to the support frames 51. The lower parts of the shock absorbers 52 are rotatably connected to the bases 53. Anti-slip patterns are provided on the lower sides of the bases 53 for stable placement. Support leg rods 54 are connected to the bases 53, and the support leg rods 54 are all connected to the centrifugal tank 1.

[0041] Using the support mechanism 5 of this device, it can support the centrifugal tank 1. When placing the centrifugal tank 1, the base 53 contacts the ground, and the centrifugal tank 1 is supported by the support leg rods 54 and the support frames 51. When the centrifugal tank 1 vibrates, part of the vibration is absorbed by the shock absorber 52, thus playing the role of being able to improve the stability of the centrifugal tank 1 during operation and prevent the centrifugal tank 1 from tipping over.

[0042] As Figure 1 and Figure 9 shown, it also includes an adjustment mechanism 6. The adjustment mechanism 6 includes a rotating cover 61, a water outlet pipe 62 and a valve 63. The lower side of the water outlet hopper 25 is threadedly connected to the rotating cover 61. The lower side of the rotating cover 61 is connected to the water outlet pipe 62, and a valve 63 is rotatably provided on the water outlet pipe 62.

[0043] Using the adjustment mechanism 6 of this device, it can adjust the water output of the water outlet hopper 25. Connect the rotating cover 61 to the water outlet hopper 25. After water enters the water outlet hopper 25, it is discharged from the rotating cover 61 and the water outlet pipe 62. By adjusting the opening of the valve 63, the water output of the water outlet pipe 62 can be adjusted to facilitate adaptation to different situations.

[0044] As Figure 1 and Figure 10As shown, it further includes a limiting mechanism 7. The limiting mechanism 7 includes a fixed seat 71, a limiting frame 72, and a fourth torsion spring 73. Five fixed seats 71 are connected to the middle of the upper cover 21. The limiting frames 72 are rotatably connected to the fixed seats 71. Limiting wheels are rotatably provided on the limiting frames 72, which are convenient for limiting the sewage pipe. Two fourth torsion springs 73 are connected between the limiting frames 72 and the connected fixed seats 71 respectively.

[0045] By using the limiting mechanism 7 of the present device, the sewage pipe can be limited. When the sewage pipe is connected to the upper cover 21, the limiting wheels on the limiting frames 72 are always in close contact with the sewage pipe under the action of the fourth torsion spring 73, so as to limit the sewage pipe and prevent the sewage pipe from loosening and falling off.
