DETAILED DESCRIPTION

[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] A centrifugal sewage treatment device, such as Figure 1-Figure 10 As shown, it includes a centrifugal tank 1, a centrifugal mechanism 2 and an oil removal mechanism 3. The centrifugal mechanism 2 is arranged on the centrifugal tank 1, and the oil removal mechanism 3 is arranged between the centrifugal tank 1 and the centrifugal mechanism 2.

[0034] like Figure 1 and Figure 3 As shown, the centrifugal mechanism 2 includes an upper cover 21, a multi-layer centrifugal filter cartridge 22, a first servo motor 23, a filter screen 24 and a water outlet bucket 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, the 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 lower side of the centrifugal tank 1 is connected to the water outlet bucket 25, and the filter screen 24 is connected inside the water outlet bucket 25.

[0035] like Figure 1 , Figure 4 and Figure 5 As shown, the oil removal mechanism 3 includes a cylinder 31, a connecting piece 32, an annular frame 33, a support rod 34, a buoy 35, a connecting rope 36 and a connecting pipe 37. The cylinder 31 is connected to the front and rear sides of the centrifugal tank 1. The connecting piece 32 is connected to the telescopic end of the cylinder 31. The connecting piece 32 is connected to the upper cover 21. Three annular frames 33 are placed on the inner side of the lower part of the multi-layer centrifugal filter cartridge 22. Two support rods 34 are connected to the upper side of the annular frame 33. The upper side of the support rods 34 is connected to the upper cover 21. The lower side of the middle part of the upper cover 21 is connected to the buoy 35 through four connecting ropes 36. The upper side of the buoy 35 is connected to the connecting pipe 37, and the connecting pipe 37 passes through the upper cover 21.

[0036] When using the present invention, firstly place the centrifugal tank 1 in the sewage treatment area, then connect the sewage pipe with the upper cover 21, then pass the sewage into the centrifugal tank 1 through the sewage pipe, and then start the first servo motor 23 to drive the multi-layer centrifugal filter cartridge 22 to rotate, and the strong centrifugal force generated separates the impurities and liquid in the sewage, and impurities of different sizes are respectively intercepted in different areas of the multi-layer centrifugal filter cartridge 22, and grease is gathered in the middle of the multi-layer centrifugal filter cartridge 22. The separated liquid enters the water outlet hopper 25 from the centrifugal tank 1, and is filtered and discharged again through the filter screen 24. When treating sewage, the connecting pipe 37 is externally connected to the oil suction pump, and the buoy 35 always floats on the sewage. On the upper side, when grease is separated from the liquid, the oil suction pump is started so that the grease is sucked into the float 35 and the connecting pipe 37 and discharged, thereby achieving multi-stage filtration treatment of sewage during centrifugation, and at the same time removing the grease separated from the water, thereby improving the sewage treatment effect. When the sewage treatment is stopped, the cylinder 31 is started 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 off the impurities on the multi-layer centrifugal filter cartridge 22, thereby achieving the function of automatically cleaning the multi-layer centrifugal filter cartridge 22 and ensuring the filtration efficiency of the multi-layer centrifugal filter cartridge 22.

[0037] like Figure 1 , Figure 6 and Figure 7 As shown, it also includes a feeding mechanism 4, which includes a second servo motor 41, a reciprocating screw rod 42, a guide rod 43, a lifting frame 44, a pressing plate 45, a barrel 46, a feeding pipe 47 and a closing component. The second servo motor 41 is connected to the upper side of the rear of the upper cover 21, and the reciprocating screw rod 42 is connected to the output shaft of the second servo motor 41. The guide rod 43 is connected to the upper side of the front of the upper cover 21. The lifting frame 44 is slidably connected to the guide rod 43. The lifting frame 44 is threadedly connected to the reciprocating screw rod 42. Four pressing plates 45 are connected to the lower side of the lifting frame 44. Four barrels 46 are connected to the upper cover 21. The pressing plates 45 are all slidably connected to the adjacent barrels 46. The two left sides A feed pipe 47 is connected between each material barrel 46 via a one-way valve, and a feed pipe 47 is also connected between the two material barrels 46 on the right side via a one-way valve. A closing assembly is provided on the upper cover 21, and the closing assembly includes a discharge frame 48, a fixing member 49, a rotating plate 410 and a third torsion spring 411. Four discharge frames 48 are connected to the lower side of the upper cover 21, and the discharge frames 48 are located on the lower sides of adjacent material barrels 46. Sixteen fixing members 49 are connected to the lower side of the upper cover 21, and a rotating plate 410 is rotatably connected between two adjacent fixing members 49, and the rotating plates 410 are located on the lower sides of adjacent discharge frames 48. A third torsion spring 411 is connected between the fixing members 49 and the rotating plates 410 connected thereto.

[0038] By using the feeding mechanism 4 of the present device, it is convenient to add chemicals to sewage. The chemicals are injected into the material barrel 46 from the feeding pipe 47, and then the second servo motor 41 is started to drive the reciprocating screw 42 to rotate, so that the lifting frame 44 moves downward along the guide rod 43, and the pressure plate 45 moves downward, and the chemicals are discharged from the bottom of the material barrel 46 into the discharge frame 48, so that the chemicals flush the rotating plate 410, and the third torsion spring 411 is deformed. When the discharge of the chemicals stops, the torsion spring recovers, driving the rotating plate 410 to return to the original position and close the discharge frame 48, thereby facilitating the addition of chemicals to sewage and improving the efficiency of sewage treatment.

[0039] like Figure 1 and Figure 8 As shown, it also includes a supporting mechanism 5, which includes a supporting frame 51, a shock absorber 52, a base 53 and a support rod 54.

When the centrifugal tank 1 is placed, the base 53 is in contact with the ground, and the centrifugal tank 1 is supported by the support rod 54 and the support frame 51. When the centrifugal tank 1 vibrates, a part of the vibration is absorbed by the shock absorber 52, thereby improving the stability of the centrifugal tank 1 during operation and preventing the centrifugal tank 1 from tipping over.

The rotating cover 61 is threadedly connected to the lower side of the water outlet bucket 25, and the lower side of the rotating cover 61 is connected to the water outlet pipe 62. The valve 63 is rotatably provided on the water outlet pipe 62.

[0042] By using the adjustment mechanism 6 of the device, the water output of the water outlet hopper 25 can be adjusted. The rotating cover 61 is connected 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 adapt to different situations.

[0043] like Figure 1 and Fig.10As shown, it also includes a limiting mechanism 7, which 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 fixed seats 71 are rotatably connected to the limiting frames 72. The limiting frames 72 are rotatably provided with limiting wheels to facilitate limiting the sewage pipe. Two fourth torsion springs 73 are connected between the limiting frames 72 and the connected fixed seats 71.

[0044] By using the limiting mechanism 7 of the device, the sewage pipe can be limited. When the sewage pipe is connected to the upper cover 21, the limiting wheel on the limiting frame 72 is always close to the sewage pipe through the force of the fourth torsion spring 73, thereby limiting the sewage pipe and preventing the sewage pipe from loosening and falling off.
