Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution: an oil filter residue device, including a bottom cylinder 1, a top cylinder 2, an oil inlet pipe 3, a booster pump 4, an oil outlet pipe 5, a sealing rubber ring 6, a middle partition board 7, a first filter material 8, a positioning card slot 9, a cross partition board 10, an inner sealing ring 11, an inner cylinder 12, a filter screen 13, a second filter material 14, an oil inlet window 15 and an oil outlet window 16. The top cylinder 2 is installed at the top of the bottom cylinder 1. The two sides of the bottom end of the bottom cylinder 1 are respectively penetrated and installed with an oil inlet pipe 3 and an oil outlet pipe 5. The booster pump 4 is installed on the oil inlet pipe 3. The oil inlet pipe 3 and the oil outlet pipe 5 are symmetrically distributed about the center of the bottom cylinder 1. The above structural design ensures that the oil enters the bottom cylinder 1 and the top cylinder 2 under appropriate pressure and ensures that the oil can flow smoothly for filter residue;

[0022] When using this device, first turn on the booster pump 4 and the valve on the oil inlet pipe 3, and the oil enters the bottom cylinder 1 through the Figure 2 oil inlet pipe 3 in it. Under the action of the oil pressure, the oil moves upward through the first filter material 8 on the left side of the middle partition board 7, and then continues to move upward through the oil inlet window 15 into the inner cylinder 12, passes through the filter screen 13 and the second filter material 14 from left to right, and flows downward through the oil outlet window 16 into the first filter material 8 on the right side of the middle partition board 7 inside the bottom cylinder 1. Finally, it passes through the first filter material 8 on the right side of the middle partition board 7 and is discharged from the oil outlet pipe 5;

[0023] A middle partition plate 7 is installed at the center of the inner wall of the bottom cylinder 1. First filter materials 8 are arranged on both sides of the middle partition plate 7 and are symmetrically distributed about the center of the middle partition plate 7. The overall height of the first filter materials 8 is greater than 3 / 4 of the overall height of the bottom cylinder 1. The above structural design ensures that the petroleum can come into contact with the first filter materials 8 for a long time and in a large area. The top end of the middle partition plate 7 is connected to the positioning card slot 9, and the positioning card slot 9 is opened at the center of the bottom surface of the cross partition plate 10. The top end of the bottom cylinder 1 is closely attached to the bottom surface of the cross partition plate 10. A sealing rubber ring 6 is installed at the joint between the top of the outer wall of the bottom cylinder 1 and the bottom of the inner wall of the top cylinder 2. The sealing rubber rings 6 are installed densely at equal horizontal intervals. The above structural design can seal between the top end of the bottom cylinder 1 and the inner wall of the top cylinder 2 to prevent petroleum leakage;

[0024] An inner cylinder 12 is fixed to the top of the cross partition plate 10. An inner sealing ring 11 is installed on the outer side surface of the cross partition plate 10, and the outer side surface of the inner sealing ring 11 is closely attached to the inner wall of the top cylinder 2. The above structural design can prevent petroleum from leaking into the gap between the top cylinder 2 and the inner cylinder 12 and ensure the internal pressure of the structure. The top of the inner cylinder 12 is snap-fitted with the top of the inner wall of the top cylinder 2. A filter screen 13 is fixedly installed between the top surface of the cross partition plate 10 and the top of the inner wall of the inner cylinder 12. Oil inlet windows 15 and oil outlet windows 16 are respectively opened on both sides of the center of the cross partition plate 10. The filter screens 13 are densely distributed at equal intervals in the middle of the inner cylinder 12. Second filter materials 14 are arranged between adjacent filter screens 13. The overall height of the filter screens 13 is greater than half of the overall height of the top cylinder 2. The above structural design can efficiently filter the petroleum entering the inner cylinder 12. The oil inlet windows 15 and the oil outlet windows 16 are symmetrically distributed about the center of the cross partition plate 10, and the top view area of the oil inlet window 15 is larger than the top view area of the oil outlet window 16. The above structural design can slow down the outflow speed of the petroleum and ensure that the petroleum can come into contact with the filter screens 13 and the second filter materials 14 in the inner cylinder 12 for a long time;

[0025] During maintenance, turn off the booster pump 4 and the valves on the oil inlet pipe 3 and the oil outlet pipe 5, remove the bolts and nuts at the connection between the top cylinder 2 and the bottom cylinder 1, move the top cylinder 2 upward to separate it from the bottom cylinder 1, clean or replace the first filter materials 8 and clean the inner side of the bottom cylinder 1. Then separate the inner cylinder 12 from the top cylinder 2, clean the inner side of the inner cylinder 12, the filter screens 13 and the second filter materials 14. Finally, snap-fit and install the inner cylinder 12 in place, connect and reset the top cylinder 2 and the bottom cylinder 1, and the whole device can filter the petroleum residue again.
