Description

Technical Field

[0001] This invention relates to the field of filtration technology, and more particularly to a hydraulic oil filtration device for hydraulic equipment. Background Technology

[0002] Hydraulic equipment refers to the general term for hydraulic devices used on ships to drive hydraulic anchor winches, steering gears, cargo winches, hatch covers, and adjustable propellers. It consists of a power unit (oil pump), an actuator (hydraulic actuator, cylinder, motor), a control unit (various control valves for pressure, flow, direction, etc.), and auxiliary parts (oil tank, pipelines, etc.). Depending on the operating environment of the hydraulic press, during use, external dust and impurities or metal particles caused by internal wear can enter the hydraulic press along with the hydraulic oil, causing wear and shortening its service life. To mitigate these problems, hydraulic presses are generally equipped with hydraulic oil filters.

[0003] Current hydraulic oil filtration devices for hydraulic equipment tend to clog over time due to impurities accumulating inside the filter element, reducing filtration permeability and efficiency. Furthermore, cleaning the filtration device requires shutting down the hydraulic equipment, further diminishing its effectiveness. Therefore, there is an urgent need to redesign a hydraulic oil filtration device for hydraulic equipment to address the problem of impurities accumulating inside the filter element and causing blockage. Summary of the Invention

[0004] The purpose of this invention is to solve the shortcomings of existing technology where impurities are scattered inside the filtration equipment and easily clog the filter element, and to propose a hydraulic oil filtration device for hydraulic equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hydraulic oil filtration device for hydraulic equipment includes two filter barrels and two cylinders, with the two cylinders respectively located at the center of the two filter barrels. A rotating rod is vertically and rotatably mounted inside each cylinder, and a helical blade is fixedly sleeved near the end of each rotating rod. A sleeve is rotatably sleeved on the top surface of each rotating rod via a sliding bearing. A cleaning mechanism for cleaning the inner wall of the cylinder is provided on a symmetrical side of each sleeve. The top of the sleeve passes through the cylinder, and a turntable is rotatably mounted at the center of the top of the filter barrel. A circular groove is formed at the bottom of the turntable, and a missing gear is fixedly mounted at the center of the top of the groove. A circular rod is vertically and fixedly mounted at the top of the rotating rod, and the top of the circular rod passes through the top of the cylinder and the filter barrel and is fixedly mounted at the center of the bottom of the missing gear. Multiple protruding teeth are fixedly mounted on the inner wall of the circular groove, evenly distributed in a semi-circular pattern. A second gear is slidably mounted inside the circular groove, meshing with both the protruding teeth and the missing gear. A rotating mechanism for rotating the sleeve is provided inside the filter barrel.

[0007] As a further technical solution of the present invention, each filter barrel is fixedly fitted with a fixing ring on the outside, and the same mounting plate is horizontally fixedly installed on one side of the two fixing rings.

[0009] As a further technical solution of the present invention, each filter barrel is vertically fixedly installed with a support rod at the bottom, and there are multiple support rods distributed in a ring at equal intervals. Multiple support rods are fixedly installed at the bottom of the cylinder, and the arc-shaped surface of the cylinder has multiple through holes, which are evenly distributed at equal intervals.

[0010] As a further technical solution of the present invention, the cleaning mechanism includes: a scraper, which is vertically arranged inside the cylinder and abuts against the inner wall of the cylinder, and two fixing rods are horizontally fixedly installed at both ends of one side of the scraper, and the other two ends of the two fixing rods are installed on one side of the sleeve.

[0011] As a further technical solution of the present invention, the top of the two filter barrels are equipped with the same first connecting pipe, and the two ends of the first connecting pipe are respectively connected to the inside of the two cylinders, and a first reversing valve is installed at the center of the first connecting pipe.

[0012] As a further technical solution of the present invention, the bottom of the two filter barrels are equipped with the same second connecting pipe, and the two ends of the second connecting pipe are respectively connected to the two filter barrels, and a second reversing valve is installed at the center of the second connecting pipe.

[0013] As a further technical solution of the present invention, a limiting plate is fixedly installed on the top of the filter bucket, and the limiting plate is U-shaped, with a turntable rotatably installed at the center of the bottom of the horizontal side of the limiting plate.

[0014] As a further technical solution of the present invention, the rotating mechanism includes: a toothed ring and a connecting rod, the toothed ring being fixedly sleeved on the surface of the sleeve and located outside the cylinder, and a first gear meshing on one side of the toothed ring.

[0015] As a further technical solution of the present invention, the connecting rod is vertically fixedly installed at the center of the top of the first gear, and the top end of the connecting rod passes through the top of the filter barrel and is fixedly installed at the center of the bottom of the second gear.

[0016] The beneficial effects of this invention are as follows:

[0017] Firstly, the present invention, through the arrangement of spiral blades and scrapers, can clean the impurities adhering to the inside of the cylinder, and the impurities will sink to the bottom with the spiral blades and will not be scattered inside the cylinder with the flow of hydraulic oil, thus ensuring the filtration efficiency of the cylinder for hydraulic oil.

[0018] Secondly, the present invention, through the setting of the filter barrel and the reversing valve, allows the two filter barrels to be used alternately, ensuring that the hydraulic equipment can operate normally even when cleaning one of the filter barrels, thereby improving the effectiveness of the equipment.

[0030] Please see the appendix Figure 1 - Appendix Figure 8 A hydraulic oil filtration device for hydraulic equipment includes two filter barrels 1 and two cylinders 10, each located at the center of its interior. Each cylinder 10 has a vertically rotatable rotating rod 14 mounted inside, with a helical blade 18 fixedly sleeved near its end. A sleeve 15 is rotatably sleeved on the top surface of each rotating rod 14 via a sliding bearing. Each sleeve 15 has a cleaning mechanism on one symmetrical side for cleaning the inner wall of the cylinder 10. The top of the sleeve 15 passes through the cylinder 10. A turntable 9 is rotatably mounted at the center of the top of the filter barrel 1, with a circular groove 24 at its bottom. A missing gear 25 is fixedly installed at the top center. A round rod 19 is vertically fixedly installed at the top of the rotating rod 14. The top of the round rod 19 passes through the top of the cylinder 10 and the filter barrel 1 and is fixedly installed at the bottom center of the missing gear 25. A tooth 26 is fixedly installed on the inner wall of the circular groove 24. There are multiple teeth 26 evenly distributed in a semi-circular shape. A second gear 23 is slidably arranged inside the circular groove 24. The second gear 23 meshes with the tooth 26 and the missing gear 25 respectively. The filter barrel 1 is equipped with a rotating mechanism for rotating the sleeve 15. Through the setting of this device, hydraulic oil can be filtered. In addition, it also prevents the filtered impurities from floating and scattering inside the cylinder 10 and clogging the through hole 11.

[0031] Please see the appendix Figure 2 - Appendix Figure 4In a preferred embodiment, each filter barrel 1 is fixedly fitted with a fixing ring 2, and the same mounting plate 3 is horizontally fixedly installed on one side of the two fixing rings 2. A limiting plate 8 is fixedly installed on the top of the filter barrel 1. The limiting plate 8 is used to limit the turntable 9. The limiting plate 8 is U-shaped. The turntable 9 is rotatably installed at the bottom center of the horizontal side of the limiting plate 8. A drive motor 13 is installed at the bottom of each filter barrel 1. A rotating shaft 12 is vertically rotatably installed at the bottom center of the filter barrel 1. The other end of the rotating shaft 12 is fixedly installed at the end of the rotating rod 14. The output shaft of the drive motor 13 is installed at the end of the rotating shaft 12. A support rod is vertically fixedly installed at the bottom of each filter barrel 1. There are multiple support rods and they are evenly distributed in a ring. The support rods are used to support the cylinder 10. Multiple support rods are fixedly installed at the bottom of the cylinder 10. Multiple through holes 11 are opened on the arc surface of the cylinder 10. The through holes 11 are evenly distributed at equal intervals to support and limit the various components, ensuring the stability of the equipment during operation.

[0032] Please see the appendix Figure 3 - Appendix Figure 5 In a preferred embodiment, the cleaning mechanism includes a scraper 17, which is vertically disposed inside the cylinder 10 and abuts against the inner wall of the cylinder 10. Both ends of one side of the scraper 17 are horizontally fixed with fixing rods 16, and the other ends of the two fixing rods 16 are installed on one side of the sleeve 15. The cleaning mechanism is used to clean the impurities attached to the through hole 11, ensuring the filtration effect of the through hole 11 on the hydraulic oil and improving the permeability of the hydraulic oil during filtration.

[0033] Please see the appendix Figure 1 - Appendix Figure 2 In a preferred embodiment, the top of the two filter barrels 1 is equipped with the same first connecting pipe 4, and both ends of the first connecting pipe 4 are connected to the interior of the two cylinders 10 respectively. A first reversing valve 5 is installed at the center of the first connecting pipe 4. The bottom of the two filter barrels 1 is equipped with the same second connecting pipe 6, and both ends of the second connecting pipe 6 are connected to the two filter barrels 1 respectively. A second reversing valve 7 is installed at the center of the second connecting pipe 6. All four ends of the first connecting pipe 4 and the second connecting pipe 6 connected to the filter barrels 1 are also equipped with check valves to prevent impurities inside the cylinders 10 from returning to the hydraulic equipment through the first connecting pipe 4.

[0034] Please see the appendix Figure 5 - Appendix Figure 8In a preferred embodiment, the rotating mechanism includes a gear ring 20 and a connecting rod 22. The gear ring 20 is fixedly sleeved on the surface of the sleeve 15 and is located outside the cylinder 10. A first gear 21 meshes with one side of the gear ring 20. The connecting rod 22 is vertically fixedly installed at the top center of the first gear 21, and the top end of the connecting rod 22 passes through the top of the filter barrel 1 and is fixedly installed at the bottom center of the second gear 23. The surface of the connecting rod 22 is rotatably installed in the inner wall of the top of the filter barrel 1 through a bearing. The rotating mechanism enables the spiral blade 18 and the scraper 17 to rotate synchronously, allowing impurities to settle to the bottom. The scraper 17 can also rotate synchronously clockwise and counterclockwise, ensuring the cleaning effect of the through hole 11.

[0035] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: First, the first connecting pipe 4 and the second connecting pipe 6 are connected to the hydraulic equipment, and the first reversing valve 5 and the second reversing valve 7 are controlled to allow hydraulic oil to enter one of the filter barrels 1. The hydraulic oil will enter the cylinder 10 through the first connecting pipe 4, and the through hole 11 will filter the impurities in the hydraulic oil. The filtered hydraulic oil will enter the filter barrel 1 through the through hole 11 and flow back to the hydraulic equipment through the second connecting pipe 6. In addition, the drive motor 1 can be used to... 3 drives the rotating shaft 12 to rotate, which in turn drives the rotating rod 14 to rotate. The rotating rod 14 then drives the round rod 19 and the spiral blade 18 to rotate. The rotation of the round rod 19 drives the missing gear 25 to rotate, which in turn drives the turntable 9 to rotate. The rotation of the turntable 9 then drives the convex tooth 26 to rotate. When the second gear 23 and the convex tooth 26 mesh, the rotation of the convex tooth 26 drives the second gear 23 to rotate clockwise. The rotation of the second gear 23 drives the connecting rod 22 to rotate, which in turn drives the first gear 21 to rotate clockwise. This will cause the gear ring 20 to rotate counterclockwise. The counterclockwise rotation of the gear ring 20 will cause the sleeve 15 to rotate. The counterclockwise rotation of the sleeve 15 will cause the fixed rod 16 and the scraper 17 to rotate counterclockwise. As the turntable 9 and the missing gear 25 rotate, the second gear 23 and the convex tooth 26 will separate, and the second gear 23 and the missing gear 25 will mesh. The rotation of the missing gear 25 will cause the second gear 23 to rotate counterclockwise. The counterclockwise rotation of the second gear 23 will cause the gear ring 20, the sleeve 15 and the scraper 17 to rotate clockwise, thereby causing the spiral blade 18 to rotate clockwise at the same time. The scraper 17 rotates in both directions simultaneously, thus scraping away impurities adhering to the inner wall of the cylinder 10 in both directions. This ensures the cleaning effect of the inner wall of the cylinder 10 and avoids the situation where one-way scraping is incomplete. Furthermore, the clockwise rotation of the spiral blade 18 prevents impurities inside the cylinder 10 from floating to the top (keeping them at the bottom) and thus prevents them from clogging the through hole 11. This improves the permeability of the hydraulic oil during filtration. When it is necessary to clean the filter canister 1 that is in use, the hydraulic oil can be circulated and filtered in another filter canister 1 simply by using the reversing valve.
