Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic oil tank technology, and in particular to a hydraulic oil tank filtration mechanism. Background Technology
[0002] A hydraulic oil tank is a container used to store the hydraulic fluid necessary for the operation of a hydraulic system. It also serves to dissipate heat, allow impurities to settle, and facilitate the escape of air from the oil. Based on whether the oil level is open to the atmosphere, hydraulic tanks can be classified into open and closed types.
[0003] For example, Chinese utility model patent application number CN202320512128.0 discloses a hydraulic oil tank filtering mechanism, relating to the field of hydraulic oil tank technology. This utility model includes a hydraulic oil tank body, an oil inlet pipe at the top of the hydraulic oil tank body, a first filter box connected to the oil inlet pipe inside the hydraulic oil tank body, multiple layers of filter screens inside the first filter box, an oil outlet pipe connected to the first filter box inside the hydraulic oil tank body, a guide box connected to the side of the first filter box outside the hydraulic oil tank body, a collection hopper at the bottom of the guide box, and the filter screens are inclined. A first connecting groove connected to the guide box is provided on the first filter box at the lower end of the filter screens. The multi-layered filter screens of this utility model perform graded filtering of the hydraulic oil, improving the filtering effect. The filtered impurities are guided into the guide box and into the collection hopper, preventing impurities from accumulating on the filter screens and affecting the filtering efficiency. The collection hopper is located outside the hydraulic oil tank body, facilitating cleaning. The collection hopper is made of transparent material, making it easy to observe the accumulation of impurities inside.
[0004] The above solution has the following shortcomings in actual use: This solution guides impurities to the collection hopper by setting an inclined filter screen, thereby avoiding the accumulation of impurities on the filter screen and the impact on filtration efficiency. However, after long-term use, impurities in the hydraulic oil can easily enter the mesh of the filter screen, making the mesh of the filter screen prone to blockage, which in turn reduces the filtration efficiency and effect of the hydraulic oil. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a hydraulic oil tank filtration mechanism.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a hydraulic oil tank filtration mechanism, comprising a housing, a feed pipe fixedly connected to the top of the housing, a moving assembly arranged between the two sides of the feed pipe, a filter plate one, a filter plate two, and a filter plate three arranged sequentially from top to bottom on the moving assembly, a motor mounted on the back of the housing via a bracket, three mounting plates fixedly connected between the two sides of the inner wall of the feed pipe, a plurality of striking columns slidingly penetrating the top of the mounting plates, a stop plate fixedly connected to the bottom ends of the plurality of striking columns, a pushing assembly arranged on one side of the inner wall of the housing, a collecting hopper fixedly connected to one side of the housing, three discharge ports opened on the side of the housing that fits against the collecting hopper, and a collecting assembly arranged on the top of the housing.
[0007] As a further description of the above technical solution:
[0008] The moving component includes three sets of mounting slots on both sides of the inner wall of the feed pipe. Two return springs are fixedly connected to the bottom of the inner wall of each set of mounting slots, and a connecting block is fixedly connected to the top of the return springs.
[0009] By adopting the above technical solution, filter plate one, filter plate two, and filter plate three can be moved downwards, thereby resetting filter plate one, filter plate two, and filter plate three.
[0010] As a further description of the above technical solution:
[0011] The top of the connecting block has a sloping surface.
[0012] As a further description of the above technical solution:
[0013] The pushing assembly includes three mounting shafts rotatably connected to one side of the inner wall of the box. Each of the three mounting shafts is fitted with several cams on its outer side. One end of each of the three mounting shafts rotatably extends through to the back of the feed pipe and is fixedly connected to a connecting gear.
[0014] By adopting the above technical solution, the abutment plate can be pushed upward, which in turn causes several impact columns to move upward and push filter plate one, filter plate two, or filter plate three upward.
[0015] As a further description of the above technical solution:
[0016] Each pair of adjacent connecting gears meshes with each other.
[0017] As a further description of the above technical solution:
[0018] The collection assembly includes a three-way pipe fixedly connected to the bottom of the collection hopper, with collection buckets threaded onto both ends of the three-way pipe, and two valves installed on the outside of the three-way pipe.
[0019] As a further description of the above technical solution:
[0020] The diameter of the mesh hole pair of the first filter plate is greater than the diameter of the mesh hole pair of the second filter plate, and the diameter of the mesh hole pair of the second filter plate is greater than the diameter of the mesh hole pair of the third filter plate.
[0021] As a further description of the above technical solution:
[0022] A sealing cap is bolted to the top of the feed pipe.
[0023] This utility model has the following beneficial effects:
[0024] 1. Compared with existing technologies, this hydraulic oil tank filtration mechanism, through the coordinated use of moving components, motors, mounting plates, striking columns, abutment plates, and pushing components, can strike the filter plate, causing it to vibrate continuously. This vibrates the filter plate, expelling impurities from the mesh holes and allowing them to slide down the inclined filter plate into the collection hopper. This effectively cleans the impurities from the mesh holes, preventing clogging and improving the hydraulic oil filtration efficiency and effect.
[0025] 2. Compared with the existing technology, this hydraulic oil tank filtration mechanism, by setting up two collection buckets for staggered use, can continue to collect impurities intercepted by the filter plate in the other collection bucket while processing the impurities inside one collection bucket. This avoids the problem of downtime caused by cleaning or replacing the collection buckets, ensures the continuity of the filtration process, and improves the practicality of the hydraulic oil tank filtration mechanism.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Reference Figure 1-5 This utility model provides a hydraulic oil tank filtration mechanism, comprising a housing 1, a feed pipe 2 fixedly connected to the top of the housing 1, a moving assembly between the two sides of the feed pipe 2, and a filter plate 3, a filter plate 4, and a filter plate 5 arranged sequentially from top to bottom on the moving assembly. A motor 6 is mounted on the back of the housing 1 via a bracket. Three mounting plates 7 are fixedly connected between the two sides of the inner wall of the feed pipe 2, and several striking posts 8 slide through the top of the mounting plates 7. The bottom ends of the striking posts 8 are all fixedly connected to an abutment plate 9. A pushing assembly is provided on one side of the inner wall of the housing 1, and a collecting hopper 10 is fixedly connected to one side of the housing 1. Three discharge ports 11 are provided on the side of the housing 1 that is in contact with the collecting hopper 10. A collecting assembly is provided on the top of the housing 1. The top of the filter plate is bolted with a sealing cap 22. The mesh hole diameter of filter plate 3 is larger than that of filter plate 4. The mesh hole diameter of filter plate 4 is larger than that of filter plate 5. The mesh hole diameter of filter plate 3 is larger than that of filter plate 4. The feed pipe 2 is square in shape. The mesh hole diameter of filter plate 4 is larger than that of filter plate 5. The top of the striking column 8 slides through to the top of the mounting plate 7 and is hemispherical in shape. The three mounting plates 7 are located below filter plate 3, filter plate 4 and filter plate 5 respectively. The three discharge ports 11 are located on one side of filter plate 3, filter plate 4 and filter plate 5 respectively. Filter plate 3, filter plate 4 and filter plate 5 are inclined inside the feed pipe 2.
[0035] The moving assembly includes three sets of mounting slots 12 on both sides of the inner wall of the feed pipe 2. Two return springs 13 are fixedly connected to the bottom of the inner wall of each set of mounting slots 12. A connecting block 14 is fixedly connected to the top of the return spring 13. The top of the connecting block 14 has an inclined surface 18. The top of the three connecting blocks 14 is higher than the height of the center part of the filter plate 1 3, filter plate 2 4 and filter plate 3 5. Each set of mounting slots 12 consists of two mounting slots 12, and the two mounting slots 12 are respectively opened on both sides of the inner wall of the feed pipe 2. The two return springs 13 are fixedly connected to the bottom of the inner wall of the two opposite mounting slots 12. The filter plate 1 3, filter plate 2 4 and filter plate 3 5 are fixedly connected between the three sets of connecting blocks 14 from top to bottom. By adopting the above technical solution, the filter plate 1 3, filter plate 2 4 and filter plate 3 5 can be moved downward, so that the filter plate 1 3, filter plate 2 4 and filter plate 3 5 are reset.
[0036] The driving assembly includes three mounting shafts 15 rotatably connected to one side of the inner wall of the housing 1. Each of the three mounting shafts 15 is fitted with several cams 16. One end of each of the three mounting shafts 15 rotatably extends to the back of the feed pipe 2 and is fixedly connected to a connecting gear 17. Every two adjacent connecting gears 17 mesh with each other. The three mounting shafts 15 are located directly below the three abutment plates 9. Several driving cams 16 are located directly below the abutment plates 9. The output end of the motor 6 is fixedly connected to one end of one of the mounting shafts 15. By adopting the above technical solution, the abutment plates 9 can be pushed upward, so that the abutment plates 9 drive several striking columns 8 to move upward and push the filter plate 1 3, filter plate 2 4 or filter plate 3 5 upward.
[0037] The collection assembly includes a three-way pipe 19 fixedly connected to the bottom of the collection hopper 10. Both ends of the three-way pipe 19 are threaded with collection buckets 20. Two valves 21 are installed on the outside of the three-way pipe 19. The two valves 21 are located above the two collection buckets 20 respectively. The collection buckets 20 are made of transparent material.
[0038] Working principle: When in use, first remove the bolts and the sealing cover 22, then pour the hydraulic oil into the feed pipe 2. The hydraulic oil then passes through filter plate 3, filter plate 4, and filter plate 5 in sequence. After three filtrations, the large, medium, and small particle sizes of impurities in the hydraulic oil are filtered onto filter plate 3, filter plate 4, and filter plate 5, respectively. Since filter plate 3, filter plate 4, and filter plate 5 are installed at an angle in the feed pipe 2, the large, medium, and small particle sizes of impurities move towards the three discharge ports 11 and fall into the collection hopper 10.
[0039] At this time, one of the valves 21 is in the open state, so that the corresponding collection bucket 20 collects the impurities. If the collection bucket 20 is full of impurities, valve 21 can be closed and another valve 21 can be opened, so that another collection bucket 20 can collect the impurities. The collection bucket 20 can be rotated to remove it from the three-way pipe 19, which makes it convenient for the staff to handle the impurities.
[0040] When it is necessary to clean the impurities inside the mesh of filter plates 3, 4, and 5, the drive motor 6 drives one of the mounting shafts 15 and the corresponding connecting gear 17 to rotate. Since the three connecting gears 17 mesh with each other, they drive the other two mounting shafts 15 to rotate. This, in turn, drives several cams 16 to rotate. When the cams 16 contact the three abutment plates 9, they push the abutment plates 9 upwards, causing several striking posts 8 to move upwards. These striking posts 8 then push filter plates 3, 4, and 5 upwards, thereby driving filter plates 3 and 4 to rotate. 4 and filter plate 5 move upward, while connecting block 14 pulls the return spring 13 upward. Then, when several cams 16 abut against the push plate, the return spring 13 resets, causing several connecting blocks 14 to drive filter plate 3, filter plate 4 and filter plate 5 to reset. This is repeated, which can drive filter plate 3, filter plate 4 and filter plate 5 to vibrate, thereby shaking out the impurities in the mesh. These impurities will enter the collection hopper 10 and fall into the collection bucket 20 because filter plate 3, filter plate 4 and filter plate 5 are installed at an angle in the feed pipe 2, thus completing the cleaning of impurities in the mesh of filter plate 3, filter plate 4 and filter plate 5.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
