[0032] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

After the solid matter in the wastewater is crushed by the crushing box 2, it falls into the filter box 3 together with the wastewater, the filtered wastewater enters the wastewater lifting chamber 5 through the conveying pipe 1 7, the filtered waste residue is sent to the centrifugal chamber 4 through the slag removal channel 6, and the wastewater centrifuged from the centrifugal chamber 4 enters the wastewater lifting chamber 5 through the conveying pipe 2 8.

[0034] The centrifugal bin 4 is tilted, and a centrifugal cylinder 9 is arranged inside the centrifugal bin 4, and an isolation bin 10 is arranged inside the centrifugal bin 4. A centrifugal motor 11 is arranged inside the isolation bin 10, and the output end of the centrifugal motor 11 passes through the isolation bin 10 and is connected to the bottom of the centrifugal cylinder 9. A movable cover 12 is arranged on the top of the centrifugal bin 4, and a spiral motor 13 is arranged on the movable cover 12. A mounting plate 14 is arranged at the output end of the spiral motor 13, and a spiral shaft 15 coaxial with the output end of the spiral motor 13 is arranged at the bottom of the mounting plate 14. A spiral auger 16 is arranged on the spiral shaft 15, and the spiral auger 16 is arranged inside the centrifugal cylinder 9. A shovel tip is arranged at the bottom of the spiral auger 16, which can scrape the filter residue at the bottom of the centrifugal cylinder 9. A slag storage tank 17 is arranged inside the centrifugal cylinder 9, and the slag storage tank 17 is connected to the mounting plate 14 by a connecting rod 18, and a filter hole 19 is opened on the slag storage tank 17. The filtered waste residue falls into the centrifugal cylinder 9. At this time, the centrifugal motor 11 is started, and the centrifugal cylinder 9 rotates to centrifuge the waste residue, so that the oil and water are completely separated from the waste residue. The separated oil and water enter the bottom of the centrifugal bin 4 through the filter hole 19 on the residue storage tank 17, and enter the wastewater lifting bin 5 through the conveying pipe 28, while the filter residue remains in the centrifugal cylinder 9. Then the spiral motor 13 is started, and the spiral auger 16 rotates to transport the waste residue in the centrifugal cylinder 9 upward. Since the centrifugal bin 4 is inclined, the waste residue falls into the residue storage tank 17 from the inclined side. The residue storage tank 17 is connected to the mounting plate 14 by a connecting rod 18 so that the residue storage tank 17 can rotate with the rotation of the spiral auger 16, so that the filter residue falls evenly in the residue storage tank 17 and the filter residue is collected.

[0035] Among them, a filter plate 20 is arranged in the filter box 3, and a cleaning mechanism 21 and a slag removal channel 6 are respectively arranged on both sides of the filter plate 20. The cleaning mechanism 21 includes a cleaning cylinder 211, a cleaning push rod 212, a U-shaped frame 213, a cleaning push plate 214 and a brush roller 215. The cleaning cylinder 211 is arranged on the outside of the filter box 3, and a cleaning push rod 212 is arranged at the output end of the cleaning cylinder 211. The U-shaped frame 213 and the cleaning push plate 214 are arranged on the cleaning push rod 212 in sequence, and the cleaning push plate 214 is arranged at the end of the cleaning push rod 212. Both sides of the brush roller 215 are penetrated on the U-shaped frame 213, and both sides of the brush roller 215 are provided with cleaning gears 22. Two racks 23 are fixed inside the filter box 3, and the two racks 23 are respectively matched with the cleaning gears 22 on both sides of the brush roller 215. When the filter residue on the filter plate 20 needs to be cleaned, the cleaning cylinder 211 is pushed out, and the cleaning push rod 212 pushes the U-shaped frame 213 and the cleaning push plate 214 to move to one side of the filter plate 20 to push the filter residue into the residue removal channel 6. At this time, the bottom of the cleaning push plate 214 is close to the upper part of the filter plate 20. During the movement of the U-shaped frame 213 above the filter plate 20, the cleaning gears 22 on both sides of the brush roller 215 rotate in coordination with the two racks 23, thereby driving the brush roller 215 to rotate, so that the brush on the brush roller 215 cleans the filter plate 20, prevents the filter plate 20 from being blocked, and improves the service life of the filter plate 20.

[0036] Among them, an isolation plate 24 is arranged in the wastewater lifting bin 5, a mounting frame 25 is arranged on the wastewater lifting bin 5, a stirring motor 26 is arranged on the mounting frame 25, a main rotating shaft 27 is arranged at the output end of the stirring motor 26, the bottom of the main rotating shaft 27 is rotatably connected with the isolation plate 24, a driving wheel 28 is arranged on the main rotating shaft 27, four stirring rotating shafts 29 are arranged inside the wastewater lifting bin 5, the tops of the four stirring rotating shafts 29 are rotatably connected with the top of the wastewater lifting bin 5, and the four stirring rotating shafts 29 are all provided with driven wheels. The four driven wheels 30 are meshed and connected with the driving wheel 28, and the four stirring shafts 29 are provided with a plurality of stirring rods 31 distributed up and down. A piston cylinder 32 is provided on one side of the wastewater lifting chamber 5, and a piston rod 33 is provided in the piston cylinder 32. The two sides of the piston cylinder 32 are respectively provided with a one-way connected air inlet pipe 34 and an air outlet pipe 35. An aeration pipe 36 is provided in the wastewater lifting chamber 5, and the aeration pipe 36 is connected with the air outlet pipe 35. A transmission mechanism 37 is provided between the piston rod 33 and the main rotating shaft 27. When the oil-water mixture is separated in the wastewater lifting chamber 5, the stirring motor 26 is started, and the driving wheel 28 on the main rotating shaft 27 rotates to drive the four driven wheels 30 to rotate, thereby rotating the four stirring rotating shafts 29, and the stirring rods 31 on the stirring rotating shafts 29 stir the oil-water mixture to prevent the liquid oil from condensing into oil blocks and causing blockage. During the stirring process of the stirring rod 31, the piston rod 33 is caused to reciprocate up and down through the transmission mechanism 37, so that the gas in the piston cylinder 32 enters the aeration pipe 36 through the outlet pipe 35, and bubbles are generated through the aeration pipe 36. These bubbles can absorb and separate the oil and water in the wastewater lifting bin 5, and accelerate the oil to the upper layer of the water, thereby realizing the effective separation of oil and water.

[0037] Among them, the transmission mechanism 37 includes a bevel gear 1, a bevel gear 2, a transmission shaft 3, a rotating rod 4, a connecting rod 5 and a chute 6. A mounting rod 38 is provided on the wastewater lifting bin 5, and the transmission shaft 3 is penetrated on the mounting rod 38. The transmission shaft 3 is rotatably connected with the mounting rod 38. The bevel gear 1 is provided on the main shaft 27. The two ends of the transmission shaft 3 are respectively provided with a bevel gear 22 and a rotating rod 4. The bevel gear 1 is meshed and connected with the bevel gear 22. The end of the rotating rod 4 away from the transmission shaft 3 is rotatably connected with the connecting rod 5. The end of the connecting rod 5 away from the rotating rod 4 is rotatably connected with the upper part of the piston rod 33. The upper part of the piston rod 33 is slidably connected in the chute 6. When the stirring motor 26 is started, the main shaft 27 rotates, and the rotation of the bevel gear on the main shaft 27 drives the rotation of the bevel gear 22, and the rotation of the bevel gear 22 drives the transmission shaft 3 and the rotating rod 4 to rotate. When the rotating rod 4 rotates, the connecting rod 5 drives the upper end of the piston rod 33 to slide up and down repeatedly in the sliding groove 6, thereby realizing the up and down reciprocating motion of the piston rod 33.

[0038] Among them, a crushing motor 39 is provided on the crushing box 2, and two mutually meshing crushing rollers 40 are provided in the crushing box 2. The ends of the rotating shafts of the two crushing rollers 40 that penetrate the crushing box 2 are respectively provided with transmission gears 41, and the two transmission gears 41 are meshed with each other. The output end of the crushing motor 39 is connected to the rotating shaft of one of the crushing rollers 40. When the crushing motor 39 is started, the crushing roller 40 connected to the output end of the crushing motor 39 rotates, and the other crushing roller 40 rotates in the opposite direction through the transmission gear 41, thereby realizing the crushing function of solid impurities in the wastewater.

[0039] Among them, springs 42 are provided at the four corners of the bottom of the filter plate 20, and the bottom of the springs 42 are fixedly connected with fixed plates 43, and the fixed plates 43 are respectively fixedly connected to the inner wall of the filter box 3. A solenoid valve 44 is provided in the water inlet pipe 1, and a pressure sensor 45 is provided inside the filter box 3. The pressure sensor 45 is electrically connected to the solenoid valve 44 and the cleaning cylinder 211. When there is no filter residue on the filter plate 20, the top of the filter plate 20 is slightly higher than the bottom of the cleaning push plate 214. As the filter residue on the filter plate 20 increases, the filter plate 20 moves downward until the pressure sensor 45 is triggered, and the top of the filter plate 20 is flush with the bottom of the cleaning push plate 214. When the pressure sensor 45 is triggered, the solenoid valve 44 in the water inlet pipe 1 is closed, the cleaning cylinder 211 is pushed out, and the cleaning push plate 214 pushes the filter residue on the filter plate 20 into the slag removal channel 6. Then the cleaning cylinder 211 is reset, and the filter plate 20 rises under the action of the spring 42. At this time, the solenoid valve 44 in the water inlet pipe 1 is opened again to filter the wastewater. Circulation.

[0040] Among them, the slag removal channel 6 is a spatial structure with a high side near the filter box 3 and a low side near the centrifugal bin 4, so that the waste slag entering the slag removal channel 6 falls into the centrifugal bin 4. A telescopic channel 46 is embedded in the side of the slag removal channel 6 near the centrifugal bin 4. A slider 47 is provided at the bottom of the telescopic channel 46. A slide rail 48 is provided at the bottom of the slag removal channel 6. The slider 47 is slidably connected in the slide rail 48. A telescopic cylinder 49 is provided at the bottom of the slag removal channel 6, and the output end of the telescopic cylinder 49 is connected to the slider 47. When conveying the filter residue, the telescopic cylinder 49 is pushed out, so that the slider 47 moves into the centrifugal bin 4 so that the telescopic channel 46 extends out. Ensure that the filter residue falls into the centrifugal barrel 9, and prevent the filter residue from entering the slag storage tank 17 when not centrifuged to affect the centrifugal effect. When the filter residue is taken out after centrifugation, the telescopic cylinder 49 is reset and the telescopic channel 46 is retracted, thereby ensuring that the connecting rod 18 can rotate in the centrifugal bin 4 without affecting the slag removal step.

[0041] Among them, the centrifugal bin 4 is provided with an observation window 50, and two lifting seats 51 are symmetrically provided on the centrifugal bin 4. The two lifting seats 51 are both provided with a lifting cylinder 52, and the output ends of the lifting cylinders 52 are both provided with lifting rods 53, and the tops of the lifting rods 53 are both connected to the movable cover 12. The internal situation of the centrifugal bin 4 is observed through the observation window 50. When the slag storage tank 17 needs to be cleaned, the lifting cylinder 52 is pushed out, driving the movable cover 12 to move up, so that the spiral auger 16 and the slag storage tank 17 move up, so as to clean and collect the filter residue.

[0042] An oil outlet pipe 54 and a water outlet pipe 55 are provided on one side of the wastewater lifting chamber 5, and a liquid level sensor 56 is provided on the inner wall of the wastewater lifting chamber 5. The separated oil and water are respectively drawn out and collected by the oil outlet pipe 54 and the water outlet pipe 55. When the liquid level sensor 56 detects that the oil level rises to a dischargeable level, the controller will instruct the oil outlet pipe 54 to start draining the oil, and after the oil is drained, the controller will instruct the water outlet pipe 55 to drain the water.

[0043] Working principle:

[0044] Wastewater falls into the crushing box 2 from the water inlet pipe 1, and the solid matter in the wastewater is crushed by the crushing box 2 and falls into the filter box 3 together with the wastewater. The filtered wastewater enters the wastewater lifting chamber 5 through the delivery pipe 1 7, and the filtered waste residue is sent to the centrifugal chamber 4 through the residue removal channel 6. The wastewater centrifuged from the centrifugal chamber 4 enters the wastewater lifting chamber 5 through the delivery pipe 2 8 for separation. When the liquid level sensor 56 detects that the oil level rises to a dischargeable level, the controller will instruct the oil outlet pipe 54 to start draining the oil. After the oil is drained, the water outlet pipe 55 will be instructed to drain the water.

[0045] As the amount of filter residue on the filter plate 20 increases, the filter plate 20 moves downward until the pressure sensor 45 is triggered, at which time the top of the filter plate 20 is flush with the bottom of the cleaning push plate 214. When the pressure sensor 45 is triggered, the solenoid valve 44 in the water inlet pipe 1 is closed, the cleaning cylinder 211 is pushed out, and the cleaning push rod 212 pushes the U-shaped frame 213 and the cleaning push plate 214 to move to one side of the filter plate 20 to push the filter residue into the residue removal channel 6. At this time, the bottom of the cleaning push plate 214 is close to the upper part of the filter plate 20. During the movement of the U-shaped frame 213 above the filter plate 20, the cleaning gears 22 on both sides of the brush roller 215 rotate in coordination with the two racks 23, thereby driving the brush roller 215 to rotate, so that the brush on the brush roller 215 cleans the filter plate 20, prevents the filter plate 20 from being blocked, and increases the service life of the filter plate 20. After the cleaning cylinder 211 is reset, the filter plate 20 rises under the action of the spring 42, and at this time the solenoid valve 44 in the water inlet pipe 1 is opened again to filter the wastewater.

[0046] The filtered waste residue falls into the centrifugal cylinder 9. At this time, the centrifugal motor 11 is started, and the centrifugal cylinder 9 rotates to centrifuge the waste residue, so that the oil and water are completely separated from the waste residue. The separated oil and water enter the bottom of the centrifugal bin 4 through the filter hole 19 on the slag storage tank 17, and enter the wastewater lifting bin 5 through the conveying pipe 28, while the filter residue remains in the centrifugal cylinder 9. Then the spiral motor 13 is started, and the spiral auger 16 rotates to transport the waste residue in the centrifugal cylinder 9 upward. Since the centrifugal bin 4 is inclined, the waste residue falls into the slag storage tank 17 from the inclined side. The slag storage tank 17 is connected to the mounting plate 14 by a connecting rod 18 so that the slag storage tank 17 can rotate with the rotation of the spiral auger 16, so that the filter residue falls evenly in the slag storage tank 17 and collects the filter residue. The internal situation of the centrifugal bin 4 is observed through the observation window 50. When the slag storage tank 17 needs to be cleaned, the lifting cylinder 52 is pushed out to drive the movable cover 12 to move up, so that the spiral auger 16 and the slag storage tank 17 move up, so that the filter residue is cleaned and collected.

[0047] When the oil-water mixture is separated in the wastewater lifting bin 5, the stirring motor 26 is started, the driving wheel 28 on the main shaft 27 rotates to drive the four driven wheels 30 to rotate, thereby rotating the four stirring shafts 29, and the stirring rod 31 on the stirring shaft 29 stirs the oil-water mixture to prevent the liquid oil from condensing into oil blocks and causing blockage. During the stirring process of the stirring rod 31, the piston rod 33 is reciprocated up and down through the transmission mechanism 37, so that the gas in the piston cylinder 32 enters the aeration pipe 36 from the outlet pipe 35, and bubbles are generated through the aeration pipe 36. These bubbles can absorb and separate the oil and water in the wastewater lifting bin 5, and accelerate the oil to the upper layer of the water, thereby achieving effective separation of oil and water.
