[0027] This utility model provides a high-efficiency lubricating oil filtration device.

[0028] Please see Figure 1 The device includes a filter housing 1, with an oil inlet pipe 14 fixedly connected to the end of the filter housing 1. The end of the oil inlet pipe 14 is designed to be open, so that the user can pour the lubricating oil into the filter housing 1 through the oil inlet pipe 14 for filtration. All connections between the parts of the device are sealed to prevent the lubricating oil from flowing out from the gaps in the connection and causing waste.

[0029] An oil outlet pipe 10 is fixedly connected to the outer surface of the filter housing 1. A storage tank 11 is fixedly connected to the end of the oil outlet pipe 10. A waste discharge pipe 12 is fixedly installed inside the filter housing 1. The other end of the waste discharge pipe 12 is fixedly connected to a waste storage box 13. Both the storage tank 11 and the waste storage box 13 are existing technologies and will not be described in detail in this application. The storage tank 11 can store the filtered lubricating oil for subsequent use. The waste storage box 13 can collect impurities from the filter. The waste storage box 13 is a drawer-type collection box, which makes it easy to clean the impurities collected inside the waste storage box 13.

[0030] Please see Figure 1 , Figure 2 and Figure 3 A connecting driven rod 8 is fixedly connected to the outer surface of the filter screen cylinder 3. A servo motor 9 is fixedly installed on the outside of the filter housing 1. A fixing plate supporting the operation of the servo motor 9 is installed on the outer surface of the filter housing 1. The servo motor 9 is fixed to the fixing plate by bolts. The fixing plate can provide support for the operation of the servo motor 9 and can prevent the servo motor 9 from rotating during operation, which would affect the normal filtration effect of the device.

[0031] The driven rod 8 passes through the filter housing 1 and is rotatably connected to the filter housing 1. The driven rod 8 is fixedly connected to the output shaft of the servo motor 9. When the servo motor 9 starts, it can drive the driven rod 8 to rotate. The rotation of the driven rod 8 can drive the filter screen cylinder 3 to rotate inside the filter housing 1. The rotation of the filter screen cylinder 3 filters the lubricating oil. The servo motor 9 provides power for the filtration operation of the device.

[0032] Please see Figure 2 and Figure 3 The filter housing 1 is rotatably connected to a filter screen cylinder 3. The filter screen cylinder 3 has mesh holes for filtering lubricating oil impurities. When the filter screen cylinder 3 rotates, the lubricating oil flows inside the filter screen cylinder 3. Impurities are blocked and retained on the inner wall of the filter screen cylinder 3, and due to their humidity, they adhere to the filter screen cylinder 3 to a certain extent. The pure lubricating oil flows out of the filter screen cylinder 3 through the mesh holes and enters the storage tank 11 through the oil outlet pipe 10 for collection and later use. By setting up the filter screen cylinder 3, the filtration efficiency of the device for lubricating oil can be improved.

[0033] A pressing plate 4 and a cleaning brush 5 are fixedly connected to the inner wall of the filter housing 1. The pressing plate 4 is located directly above the cleaning plate 603. By setting the pressing plate 4, it can form a squeezing action on the filter screen cylinder 3 with the cleaning plate 603 when the filter screen cylinder 3 rotates, so that the cleaning plate 603 can better clean the impurities on the inner wall of the filter screen cylinder 3 and sweep the impurities into the collection box 601 for collection. The cleaning brush 5 has hard bristles, which can clean the mesh and prevent some impurities from clogging the mesh and affecting the filtration effect of the filter screen cylinder 3. The cleaned impurities will fall back into the filter screen cylinder 3 for filtration and recycling.

[0034] Please see Figure 3 The filter screen cylinder 3 is equipped with a collection mechanism 6 for recovering impurities. The collection mechanism 6 includes a collection box 601. A fixing frame 7 is fixedly connected to the outside of the collection box 601. The end of the fixing frame 7 is fixedly connected to the filter housing 1. The fixing frame 7 is a tripod composed of three connecting rods, which can provide stable support for the use of the collection box 601, enabling the collection box 601 to perform the collection and transmission of impurities normally, thus improving the stability of the device.

[0035] Please see Figure 3 and Figure 4 The top surface of the collection box 601 is fixedly connected to two fixed connecting plates 602. A cleaning plate 603 is provided above the collection box 601. The two ends of the cleaning plate 603 are fixedly connected to the two fixed connecting plates 602 respectively. The cleaning plate 603 is in contact with the inner wall of the filter screen cylinder 3. When the filter screen cylinder 3 rotates to the position of the cleaning plate 603, the cleaning plate 603 can sweep the impurities on the inner wall of the filter screen cylinder 3 into the collection box 601 for collection.

[0036] The collection box 601 is rotatably connected to a push screw 604. One end of the discharge pipe 12 is fixedly connected to the collection box 601. When the push screw 604 rotates, it can push the impurities collected inside the collection box 601 into the discharge pipe 12. The discharge pipe 12 has a certain inclination to ensure that the impurities can be transported to the storage box 13 for collection under the action of gravity.

[0037] One end of the push screw 604 is fixedly connected to a transmission connecting rod 605. The transmission connecting rod 605 passes through the collection box 601 and is rotatably connected to the collection box 601. The end of the transmission connecting rod 605 is fixedly connected to the filter screen cylinder 3. While the filter screen cylinder 3 rotates to filter impurities, it can also drive the push screw 604 to rotate through the transmission connecting rod 605, providing power for the push screw 604 to push impurities. This simplifies the power structure of the device and improves the energy utilization efficiency of the device.

[0038] Working principle: When the operator wants to use this application to filter lubricating oil, first start the servo motor 9, then pour the lubricating oil into the oil inlet pipe 14. The lubricating oil enters the interior of the filter screen cylinder 3 through the oil inlet pipe 14. The start of the servo motor 9 can drive the filter screen cylinder 3 to rotate through the driven rod 8, thereby filtering the lubricating oil. The filtered impurities will adhere to the inner wall of the filter screen cylinder 3. When the impurities rotate with the filter screen cylinder 3 and come into contact with the cleaning plate 603, the cleaning plate 603 will sweep the impurities into the interior of the collection box 601. The rotation of the filter screen cylinder 3 can also drive the push screw 604 to rotate through the transmission connecting rod 605. The rotation of the push screw 604 can push the impurities collected in the collection box 601 into the discharge pipe 12. The impurities will enter the storage box 13 for collection through the discharge pipe 12 under the action of gravity. The filtered lubricating oil will enter the storage tank 11 for later use through the oil outlet pipe 10.
