Description

Technical Field

[0001] This utility model relates to the field of oil filter technology, specifically an oil filter that is easy to clean. Background Technology

[0002] An oil filter is a device used to remove impurities from oil and is widely used in industrial fields. One of the core components of an oil filter is the filter screen, which filters particulate matter from the oil through physical interception. However, as the filtration process continues, impurities gradually accumulate on the surface of the filter screen, leading to a decrease in filtration efficiency. Therefore, regularly cleaning the filter screen is crucial to ensuring the efficient operation of the oil filter.

[0003] Currently, many oil filtration machines use scraper cleaning devices to clean the filter screen. The scraper is usually installed inside the filter screen and removes impurities attached to the inner wall of the filter screen by rotating or reciprocating motion. However, the scraper is always in contact with the inner wall of the filter screen when not in use. The continuous contact between the scraper and the inner wall of the filter screen will cause the surface of the filter screen to be subjected to friction for a long time, which will accelerate the wear of the filter screen and shorten its service life. In order to solve the above problems, the inventor proposes an oil filtration machine that is easy to clean. Utility Model Content

[0004] In order to solve the problem of the retractable scraper of the oil filter, the purpose of this utility model is to provide an oil filter that is easy to clean.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: an easy-to-clean oil filter, comprising a filter cylinder, a filter frame placed inside the filter cylinder, a cylinder cover fixedly installed at the top of the filter cylinder, a rotating rod rotatably connected to the middle of the cylinder cover, the bottom end of the rotating rod extending into the interior of the filter frame, a scraper provided on the side of the bottom of the rotating rod, an adjusting component provided on the rotating rod, the adjusting component being used to adjust the distance between the scraper and the inner wall of the filter frame, an L-shaped plate fixedly connected to the top of the cylinder cover, a servo motor fixedly installed at the top of the L-shaped plate, the drive end of the servo motor being fixedly connected to the rotating rod, an inlet pipe communicating with the interior of the filter cylinder fixedly connected to one side of the top of the filter cylinder, and an outlet pipe communicating with the interior of the filter cylinder fixedly connected to one side of the bottom of the filter cylinder.

[0006] Preferably, the adjusting assembly includes a connecting plate, a crossbar is provided between the connecting plate and the rotating rod, a movable rod is movably inserted inside the rotating rod, a sliding groove is provided on one side of the rotating rod, a slider is slidably engaged inside the sliding groove, the slider is fixedly connected to the movable rod, a through groove is provided on one side of the top of the rotating rod, two fixed plates are fixedly connected to the side of the rotating rod near the through groove, a threaded rod is rotatably connected between the two fixed plates, a movable plate is threadedly connected to the outside of the threaded rod, the movable plate is slidably engaged in the through groove, the movable plate is fixedly connected to the movable rod, and the top end of the threaded rod extends to the top end of the fixed plate and is fixedly connected to a knob.

[0007] Preferably, a mounting plate is provided on one side of the scraper, the scraper is disposed on one side of the mounting plate, and two guide rods are fixedly connected to the side of the mounting plate away from the scraper. The end of each guide rod away from the mounting plate movably passes through a connecting plate and is fixedly connected to a limit block. A spring is movably sleeved on the outside of the limit block and located between the mounting plate and the connecting plate.

[0008] Preferably, an annular seat is fixedly connected inside the filter cylinder, and two symmetrically distributed slots are opened on the inner side of the annular seat. Two symmetrically distributed locking blocks are fixedly connected to the top surface of the filter frame, and the locking blocks are movably engaged in the slots.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. During cleaning, turning the knob will rotate the threaded rod, which in turn moves the moving plate downwards along the outside of the threaded rod. This, in turn, moves the movable rod and slider downwards. Utilizing the connecting action of the cross rod, the connecting plate and scraper are pushed towards one side of the inner wall of the filter frame, allowing the scraper to contact the inner wall of the filter frame. When not cleaning, the scraper is separated from the filter frame to avoid the problem of continuous contact between the scraper and the inner wall of the filter screen, which would cause long-term friction on the filter screen surface and accelerate filter screen wear. 2. By incorporating a spring, the scraper is ensured to always contact the filter frame with appropriate pressure, avoiding damage to the filter frame due to excessive pressure or incomplete cleaning due to insufficient pressure.

[0017] 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.

[0018] Example: Figure 1-5 As shown, this utility model provides an easy-to-clean oil filter, including a filter cylinder 1, a filter frame 2 placed inside the filter cylinder 1, a cylinder cover 3 fixedly installed at the top of the filter cylinder 1, a rotating rod 4 rotatably connected to the middle of the cylinder cover 3, the bottom end of the rotating rod 4 extending into the interior of the filter frame 2, a scraper 5 provided on the side of the bottom of the rotating rod 4, an adjustment component 6 provided on the rotating rod 4, the adjustment component 6 being used to adjust the distance between the scraper 5 and the inner wall of the filter frame 2, an L-shaped plate 11 fixedly connected to the top of the cylinder cover 3, a servo motor 12 fixedly installed at the top of the L-shaped plate 11, and the drive end of the servo motor 12 fixedly connected to the rotating rod 4.

[0019] The adjustment assembly 6 includes a connecting plate 61, a cross rod 62 is provided between the connecting plate 61 and the rotating rod 4, a movable rod 63 is movably inserted inside the rotating rod 4, a sliding groove 64 is provided on one side of the rotating rod 4, a slider 65 is slidably engaged inside the sliding groove 64, and the slider 65 is fixedly connected to the movable rod 63.

[0020] By adopting the above technical solution, the slider 65 moves vertically along the inside of the slide groove 64, and the connecting plate 61 is pushed to move away from or closer to the rotating rod 4 by the connecting action of the cross rod 62, thereby adjusting the distance between the scraper 5 and the inner wall of the filter frame 2. When the scraper 5 is needed, the front end of the scraper 5 contacts the inner wall of the filter frame 2, and vice versa.

[0021] A through groove 66 is provided on one side of the top of the rotating rod 4. Two fixed plates 67 are fixedly connected to the side of the rotating rod 4 near the through groove 66. A threaded rod 68 is rotatably connected between the two fixed plates 67. A movable plate 69 is threadedly connected to the outside of the threaded rod 68. The movable plate 69 is slidably engaged in the through groove 66. The movable plate 69 is fixedly connected to the movable rod 63. The top end of the threaded rod 68 extends to the top end of the fixed plate 67 and is fixedly connected to a knob 16.

[0022] By adopting the above technical solution, rotating the knob 16 drives the threaded rod 68 to rotate, and at the same time drives the moving plate 69 to move vertically along the outside of the threaded rod 68, thereby driving the movable rod 63 to move vertically, realizing the unfolding and retraction operation of the scraper 5.

[0023] A mounting plate 7 is provided on one side of the scraper 5. The scraper 5 is located on one side of the mounting plate 7. Two guide rods 8 are fixedly connected to the side of the mounting plate 7 away from the scraper 5. The end of each guide rod 8 away from the mounting plate 7 moves through the connecting plate 61 and is fixedly connected to a limit block 9.

[0024] By adopting the above technical solution, the guide rod 8 can guide the displacement of the scraper 5 towards the connecting plate 61, thereby improving the stability of the scraper 5 when it moves. The limit block 9 can limit the relative displacement between the scraper 5 and the connecting plate 61, ensuring the stability of the connection between the scraper 5 and the connecting plate 61.

[0025] A spring 10 is movably sleeved on the outside of the limiting block 9 and located between the mounting plate 7 and the connecting plate 61.

[0026] By adopting the above technical solution and setting the spring 10, it is ensured that the scraper 5 always contacts the filter frame 2 with appropriate pressure, so as to avoid damage to the filter frame 2 due to excessive pressure or incomplete cleaning due to insufficient pressure.

[0027] The filter cartridge 1 is fixedly connected to an annular seat 13. Two symmetrically distributed slots 14 are opened on the inner side of the annular seat 13. Two symmetrically distributed locking blocks 15 are fixedly connected to the top surface of the filter frame 2. The locking blocks 15 are movably locked in the slots 14.

[0028] By adopting the above technical solution, the rotation of the filter frame 2 can be limited through the cooperation between the slot 14 and the block 15, so that the filter frame 2 will not rotate when the scraper 5 scrapes the inner wall of the filter frame 2, thereby improving the stability of the structure.

[0029] A liquid inlet pipe 17 communicating with the inside of the filter cylinder 1 is fixedly connected to one side of the top of the filter cylinder 1, and a liquid outlet pipe 18 communicating with the inside of the filter cylinder 1 is fixedly connected to one side of the bottom of the filter cylinder 1.

[0030] By adopting the above technical solution, the oil enters the interior of the filter cylinder 1 through the inlet pipe 17, and after being filtered by the filter frame 2, the filtered oil is finally discharged through the outlet pipe 18.

[0031] Working principle: When filtering oil, the oil is introduced into the filter cylinder 1 from one end of the inlet pipe 17 and enters the inner side of the filter frame 2. When it flows out from the inside of the filter frame 2 to the outside, the filter frame 2 is used to filter the impurities in the oil. Finally, the filtered oil is discharged through the outlet pipe 18. After filtering for a period of time, impurities will gradually accumulate on the inner wall of the filter frame 2. When cleaning, by turning the knob 16, the threaded rod 68 is rotated, and the moving plate 69 is moved downward along the outside of the threaded rod 68. This causes the movable rod 63 to move downward along the inner wall of the rotating rod 4, and the slider 65 to move downward along the inside of the slide groove 64. Using the connecting action of the cross rod 62, the connecting plate 61 is pushed to one side of the inner wall of the filter frame 2, so that the scraper 5 contacts the inner wall of the filter frame 2. Then, the servo motor 12 drives the slide groove 64 to rotate, and at the same time, the scraper 5 scrapes along the inner wall of the filter frame 2 to clean the inner wall of the filter frame 2. When it is not necessary to clean the filter frame 2, the knob 16 is turned in the opposite direction, and the scraper 5 is no longer in contact with the filter frame 2. During the scraping process of the scraper 5, the spring 10 is set to ensure that the scraper 5 always contacts the filter frame 2 with appropriate pressure, so as to avoid damage to the filter frame 2 due to excessive pressure or incomplete cleaning due to insufficient pressure.

[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
