[0002] Tank trucks are mainly used to transport and store petroleum derivatives such as gasoline, diesel, crude oil, lubricating oil and coal tar. During transportation, due to the different properties of the goods, complex composition, long-distance driving and other factors, a lot of dirt and residue will accumulate inside the tank. If not cleaned in time, it will lead to unpleasant odors, bacterial growth, and mixing of dangerous goods in the vehicle body. Therefore, regular cleaning of tank trucks is crucial. When cleaning tank trucks, a large amount of dirty oil-water mixture will be generated. If discharged directly, it will cause environmental pollution and waste of resources. Therefore, the oil and water in the oil-water mixture must be separated so that the water can be recycled and the oil can be recovered, bringing economic and environmental benefits.

The gas-liquid mixing pump 4 uses negative pressure to inhale air from the outside and mixes the oil-water mixture inhaled from the liquid inlet pipe 6 with the air inhaled from the outside, so that the air and the oil-water mixture are fully dissolved, which is convenient for emulsification and separation of the oil-water mixture; an oil suction pump 3 is installed on the upper end of the sedimentation separation tank 1, and a heating rod 2 is embedded in the upper end of the sedimentation separation tank 1 near the oil suction pump 3. When the grease floating on the upper end of the sedimentation separation tank 1 solidifies and the oil suction pump 3 cannot extract the solidified grease, the heating rod 2 can be used to heat the grease to melt it; a drain pipe 12 is connected to the end of the outer side of the sedimentation separation tank 1 away from the connecting pipe 11. After opening the drain pipe 12, the clean water in the middle of the sedimentation separation tank 1 can be discharged; There is a cyclone 13. When the emulsified oil-water mixture enters the cyclone 13, it rotates at high speed on the inner wall of the cyclone 13. Due to the action of centrifugal force, the oil, water and fixed impurities will be forced to separate; the grease floats on the upper part of the sedimentation separation tank 1, the water is located in the middle part of the sedimentation separation tank 1, and the fixed impurities sink to the lower part of the sedimentation separation tank 1. The input end of the oil suction pump 3 is connected to the oil suction hose 14, and the output end of the oil suction pump 3 is connected to the oil outlet hose 7. One end of the oil outlet hose 7 is connected to the oil bucket 8. The lower end of the oil suction hose 14 is embedded in the upper end of the sedimentation separation tank 1. After starting the oil suction pump 3, the grease floating on the upper end of the sedimentation separation tank 1 is sucked into the oil outlet hose 7 through the oil suction hose 14, and then flows from the oil outlet hose 7 into the oil bucket 8 for recycling. The bottom end of the sedimentation separation tank 1 is connected to a mud discharge pipe 10, and one end of the mud discharge pipe 10 is fixedly connected to a mud suction pump 9. After starting the mud suction pump 9, the sludge and other fixed debris settled in the lower part of the sedimentation separation tank 1 can be discharged through the mud discharge pipe 10.

The upper end of the filter box body 51 is rotatably connected to the filter box cover 53. The front and rear ends of the filter basket 57 are fixedly connected to two sets of pulleys 56. A set of hanging rings 55 are fixedly connected to the inner side of the upper end of the filter basket 57. A liquid inlet 54 is provided at one end of the filter basket 57.

The other end of the filter element 1 is fixedly connected to the connecting pipe 11, the liquid inlet nozzle 52 is fixedly connected to the liquid inlet pipe 6, and the liquid inlet port 54 corresponds to the liquid inlet nozzle 52. The oil-water mixture generated by the cleaning tank truck enters the filter basket 57 from the liquid inlet pipe 6, the liquid inlet nozzle 52 and the liquid inlet port 54 in sequence. The large particles of solid in the oil-water mixture are intercepted by the filter basket 57, and the filtered oil-water mixture flows into the sedimentation separation tank 1 through the connecting pipe 11. When enough impurities are intercepted in the filter basket 57, the filter box cover 53 is opened, and the hanging ring 55 is hung by the external hook, the filter basket 57 can be lifted out of the filter box body 51 to pour out the impurities in the filter basket 57.

[0024] exist Figure 3 and Figure 4 In the embodiment, the cleaning assembly 58 includes a wire brush 583, the upper end of the wire brush 583 is fixedly connected to a swing arm 585, the upper end of the swing arm 585 is installed with a bearing seat 586 containing a bearing inside, a slider 584 is slidably connected to the outer side of the swing arm 585, one end of the slider 584 is rotatably connected to a connecting rod 582, one end of the connecting rod 582 is fixedly connected to a motor 581, the bearing seat 586 and the motor 581 are both installed on the outer wall of the filter box 51, the wire brush 583 is closely attached to one side of the filter basket 57, and the motor 581 drives the connecting rod 582 and the slider 584 to rotate, so that the slider 584 slides along the swing arm 585 while rotating, thereby driving the swing arm 585 and the wire brush 583 to swing together with the bearing seat 586 as the center of the circle. During the swinging process of the bearing seat 586, one side of the filter basket 57 is cleaned, which can effectively prevent one side of the filter basket 57 from being blocked, thereby causing the oil-water mixture to flow poorly.

[0025] The working principle of this utility model:

[0026] First, the oil-water mixture generated by cleaning the tank truck enters the filter basket 57 from the liquid inlet pipe 6, the liquid inlet nozzle 52 and the liquid inlet 54 in sequence. The large particles of solid in the oil-water mixture are intercepted by the filter basket 57, and the filtered oil-water mixture enters the connecting pipe 11.

[0027] At this time, the gas-liquid mixing pump 4 is turned on. The gas-liquid mixing pump 4 uses the negative pressure to inhale air from the outside, and mixes the oil-water mixture inhaled from the liquid inlet pipe 6 with the air inhaled from the outside, so that the air and the oil-water mixture are fully emulsified and separated; after the emulsified oil-water mixture enters the cyclone cylinder 13, it rotates at a high speed on the inner side wall of the cyclone cylinder 13. Due to the action of centrifugal force, the oil, water and fixed impurities are forcibly separated; the oil floats on the upper part of the sedimentation separation tank 1, the water is located in the middle part of the sedimentation separation tank 1, and the fixed impurities sink to the lower part of the sedimentation separation tank 1.

[0028] When enough grease accumulates in the upper part of the sedimentation separation tank 1, the oil suction pump 3 is turned on, and the grease is sucked into the oil outlet hose 7 through the oil suction hose 14 at the input end of the oil suction pump 3, and then flows from the oil outlet hose 7 into the oil bucket 8 for recycling; when enough clean water accumulates in the middle part of the sedimentation separation tank 1, the drain pipe 12 is opened to discharge the clean water for recycling; when enough fixed debris accumulates in the lower part of the sedimentation separation tank 1, the mud suction pump 9 is turned on to discharge the fixed debris through the mud discharge pipe 10; when enough impurities are trapped in the filter basket 57, the filter box cover 53 is opened, and the hanging ring 55 is hung by the external hook, the filter basket 57 can be lifted out of the filter box body 51 to pour out the impurities in the filter basket 57.

[0029] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
