Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of 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] Such as Figures 1 to 5As shown in the figure, a cleaning filter element for lubricating oil production includes a filter box 1. Inside the filter box 1, a partition plate 2 is fixedly connected. At the top of the filter box 1, a shunt pipe 3 is connected. At the top of the shunt pipe 3, an oil inlet pipe 4 is connected. On both sides of the front of the shunt pipe 3, a stepping motor 5 is fixedly connected. The output ends of the stepping motors 5 penetrate into the interior of the shunt pipe 3 and are fixedly connected with a throttle plate 6. The front and rear ends of the throttle plate 6 are in contact with the inner wall of the shunt pipe 3. On the top and bottom surfaces of the throttle plate 6, telescopic grooves 7 are opened. Inside the inner walls of the telescopic grooves 7, a number of first springs 8 are fixedly connected. On the outer sides of the first springs 8, rubber blocks 9 are fixedly connected. The rubber blocks 9 are slidably connected with the telescopic grooves 7. On both sides of the front of the filter box 1, installation grooves 10 are opened. The installation grooves 10 penetrate through the partition plate 2 and extend to the rear wall of the filter box 1. Inside the installation grooves 10, a connecting frame 11 is slidably connected. Inside the connecting frame 11, a filter element 12 is fixedly connected. On both sides of the front of the filter box 1, a confluence pipe 13 is connected. At the front end of the confluence pipe 13, an oil outlet 14 is connected. When the throttle plate 6 rotates to the vertical position, the first springs 8 on its upper and lower sides will extend outwards to make the rubber blocks 9 fit more tightly with the inner wall of the shunt pipe 3, avoiding oil leakage and thus improving the throttling effect.

[0022] Reference Figure 1 and Figure 2 On the left side of the filter box 1, a waste residue tank 15 is provided. On the front of the waste residue tank 15, a slot 16 is opened. On the left side of the waste residue tank 15, an air pump 17 is provided. The output end of the air pump 17 is connected with a hollow pipe 18. At the bottom of the hollow pipe 18, a number of air nozzles 19 are connected. The air nozzles 19 are all located at the top of the waste residue tank 15.

[0023] As a technical optimization scheme of the present utility model, through the setting of the air pump 17, after the connecting frame 11 and the filter element 12 are removed, they are turned over and inserted into the slot 16. Then, the air pump 17 is started to input air flow into the interior of the hollow pipe 18, and the air flow is ejected through the air nozzles 19 to blow the impurities filtered out on the surface of the filter element 12 into the interior of the waste residue tank 15. The cleaning is simple and fast, and it avoids the problem that when the filter element 12 is washed with water flow, residual water will remain inside it, affecting the quality of the filtered oil.

[0024] Reference Figure 2 On both sides inside the filter box 1, a diversion box 20 is fixedly connected. At the top of each diversion box 20, a diversion pipe 21 is connected. The diversion pipes 21 are all connected with the shunt pipe 3. On the bottom wall of the diversion box 20, a number of diversion holes 22 are opened.

[0025] As a technical optimization solution of the present utility model, through the setting of the diversion box 20, the oil products on both sides of the shunt pipe 3 can be blocked by the bottom wall of the diversion box 20 and inclinedly diverted through the diversion holes 22, making the distribution of the oil products more uniform and reducing the impact force, avoiding the problem that the local impact of the oil products on the filter element 12 causes a significant increase in its cleaning frequency, and further improving the practicability of the filter element.

[0026] Reference Figure 1 , Figure 2 and Figure 5 , both ends of the two side surfaces of the filter box 1 and both ends of the outer side surface of the connecting frame 11 are provided with limiting holes 23. Both ends of the two side surfaces of the filter box 1 are fixedly connected with second springs 24. The outer sides of the second springs 24 are fixedly connected with pull plates 25. The inner sides of the pull plates 25 are fixedly connected with limiting rods 26. The limiting rods 26 are all located inside the second springs 24, and the inner ends of the limiting rods 26 are slidably connected with the limiting holes 23.

[0027] As a technical optimization solution of the present utility model, through the setting of the second spring 24 and the limiting rod 26, pull the pull plate 25 to stretch the second spring 24 and drive the limiting rod 26 to move outward. Then insert the connecting frame 11 and the filter element 12 into the installation groove 10, and release the pull plate 25 to make the second spring 24 contract and drive the limiting rod 26 to sequentially insert into the limiting holes 23 on the sides of the filter box 1 and the connecting frame 11 to complete the fixation, thereby avoiding the problem that the connecting frame 11 slides under the impact of the oil products, resulting in the oil products overflowing from the filter box 1.

[0028] Reference Figure 1 , Figure 2 and Figure 5 , the outer sides of the pull plates 25 are fixedly connected with connecting blocks 27, and the outer sides of the connecting blocks 27 are fixedly connected with pull rods 28. Anti-slip patterns are provided on the surfaces of the pull rods 28.

[0029] As a technical optimization solution of the present utility model, through the setting of the pull rod 28, when the connecting frame 11 is released from fixation, the pull rod 28 can be pulled to drive the two-sided pull plates 25 to be pulled simultaneously, thereby avoiding the problem that a single person needs to pull the pull plates 25 with both hands and also needs the assistance of others to pull out the connecting frame 11, making the loading and unloading of the filter element 12 more convenient and further improving the loading and unloading efficiency.

[0030] Reference Figure 1 , Figure 2 and Figure 5 , the left side of the filter box 1 is fixedly connected with a fixed block 29. T-shaped grooves 30 are provided on the outer surface of the fixed block 29. The right side of the air nozzle 19 is fixedly connected with a T-shaped block 31, and the T-shaped block 31 is slidably connected with the T-shaped groove 30.

[0031] As a technical optimization solution of the present utility model, through the setting of the fixed block 29, the hollow tube 18 is provided with limit support. At the same time, the hollow tube 18 can be pulled to make the T-shaped block 31 slide back and forth inside the T-shaped groove 30, so that the filter element 12 is cleaned more evenly, avoiding the problem of incomplete local cleaning.

[0032] The working principle and usage process of the present utility model: When in use, the user connects the oil inlet pipe 4 with the oil pipe to be filtered, and connects the oil outlet 14 with the delivery oil pipe. Then the oil product will be diverted through the diversion pipe 3 into the inside of the diversion box 20. After being blocked by the bottom wall of the diversion box 20 and obliquely diverted by the diversion holes 22, the oil product is more evenly distributed. Then it is filtered by the filter element 12 and led out from the confluence pipe 13 and the oil outlet 14. When the filter element 12 needs to be cleaned, first start the stepping motor 5 on one side to rotate the intercepting plate 6 by 90°, from horizontal to vertical, so as to cut off the oil product on the same side, making the oil product only flow to the filter element on the other side for filtration. Then pull the pull rod 28 on the same side to drive the pull plates 25 on both sides to pull simultaneously. The pull plate 25 stretches the second spring 24 and drives the limit rod 26 to move outward. The limit rod 26 will then disengage from the limit hole 23, and the connecting frame 11 and the filter element 12 can be taken out. After flipping, they are inserted into the slot 16, and the air pump 17 is started to input air flow into the hollow tube 18, and the air flow is ejected through the air nozzle 19 to blow the impurities filtered out on the surface of the filter element 12 into the waste residue tank 15. At the same time, the hollow tube 18 is slid back and forth to clean all parts of the filter element 12. After cleaning, pull the pull rod 28 on the same side to drive the pull plates 25 on both sides to pull simultaneously. The pull plate 25 stretches the second spring 24 and drives the limit rod 26 to move outward. Then insert the connecting frame 11 and the filter element 12 back into the installation groove 10, and control the stepping motor 5 on the same side to rotate 90° again, so that the intercepting plate 6 changes from vertical to horizontal to allow the oil product to continue to flow. Repeat the above steps when cleaning the filter element 12 on the other side.
