Description

A filter element mechanism for lubricating oil filtration Technical Field

[0001] This utility model relates to the field of filter element technology, specifically a filter element mechanism for filtering lubricating oil. Background Technology

[0002] The filter element is the heart of the filter, as its name suggests. The filter element, and the core principle of the filter, is to purify raw resources and facilitate their reuse. Filter elements are commonly used in oil filtration, water filtration, and air filtration. A lubrication pump, as the oil source for a lubrication system, provides lubricating oil or grease at regular intervals. It is widely used in mechanical equipment. Its basic structure includes a motor, pump body, and oil tank. The oil inlet of the oil tank is often equipped with a lubricating oil filter to remove impurities from the lubricating medium entering the tank.

[0003] Based on the above, the inventors have discovered the following problems: after filtering lubricating oil, the inner wall of the filter screen of the current filter element is easily clogged by oil and impurities. In addition, some oils are quite viscous, which causes the filter screen mesh to become clogged. When the filter element with clogged mesh filters lubricating oil again, it will affect the filter element's filtration and purification effect on lubricating oil.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a filter element mechanism for lubricating oil filtration in order to achieve a more practical value. Summary of the Invention

[0005] The purpose of this invention is to provide a filter element mechanism for lubricating oil filtration to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A filter element mechanism for filtering lubricating oil includes a filter element body, a connecting assembly, and a cleaning assembly. The filter element body includes a top ring and a bottom ring, with a filter cartridge installed between the top ring and the bottom ring. The cleaning assembly includes an outer scraper and an inner scraper, which are respectively located outside and inside the filter cartridge. The opposing sides of the outer and inner scrapers are arc-shaped. The inner scraper has several bristles on its side near the filter cartridge. The opposing sides of the outer and inner scrapers are respectively in contact with the outer wall and the inner wall of the filter cartridge. A third threaded hole is opened inside the bottom end of both the outer and inner scrapers. Threaded posts are threaded into the interior of two of the third threaded holes. A connecting seat is connected between the ends of a pair of threaded posts away from the outer scraper. The cleaning assembly also includes a hollow cylinder. A rotating rod is rotatably connected to the bottom end of the hollow cylinder. A connecting strip is installed at the bottom end of the rotating rod, and the upper end of the connecting strip is fixedly connected to the bottom end of the connecting seat.

[0008] Furthermore, the hollow cylinder is disposed inside the filter cartridge near the upper end, and the central axis of the hollow cylinder is collinear with the central axis of the filter cartridge. A micro servo motor is installed inside the hollow cylinder, and the output end of the micro servo motor is connected to the rotating rod via a transmission.

[0009] The beneficial effect of adopting the above-mentioned further solution is that by setting a micro servo motor, when the micro servo motor works, it drives the rotating rod to rotate. Since the bottom end of the rotating rod is equipped with a connecting strip, the upper end of the connecting strip is equipped with a connecting seat, and the top end of the connecting seat is connected to the outer scraper and the inner scraper through a threaded post, thereby realizing the cleaning of the outer wall of the filter cartridge by the outer scraper and the cleaning of the inner wall of the filter cartridge by the inner scraper.

[0010] Furthermore, the bottom ring has an annular groove on the side away from the filter cartridge, and a round rod is provided inside the annular groove. The bottom end of the round rod is fixedly connected to the upper end of the connecting seat, and the outer wall of the round rod is slidably engaged with the inner wall of the annular groove.

[0011] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of the annular groove and the round rod, when the rotating rod causes the connecting seat to rotate under the action of the connecting bar, the round rod moves inside the annular groove, so that the cleaning component will not easily shake during rotation, thereby improving the stability of cleaning.

[0012] Furthermore, the filter cartridge has several through holes on its outer side, the outer diameter of the brush bristles is smaller than the inner diameter of the through holes, the brush bristles are evenly distributed, and the brush bristles are made of nylon.

[0013] The beneficial effects of adopting the above-mentioned further solution are that the filter cartridge is made of stainless steel filter mesh, the through holes on the outside of the filter cartridge allow lubricating oil to pass through smoothly, and since the outer diameter of the brush bristles is smaller than the inner diameter of the mesh of the filter cartridge, the brush bristles can be inserted into the mesh inside the filter cartridge, which can better clean the mesh. At the same time, the brush is made of nylon, which gives the brush bristles a certain degree of hardness, thereby improving the cleaning effect.

[0014] Furthermore, the connecting assembly includes a connecting plate, the bottom end of which is fixedly connected to the upper end of the hollow cylinder. The inner wall of the top ring is equipped with a plurality of positioning strips, the number of which is six. The opposite sides of an adjacent pair of positioning strips form a positioning groove. The outer wall of one end of the connecting plate slides into the inner wall of the positioning groove, the number of which is three.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, since there are six positioning strips and three positioning grooves are formed between adjacent pairs of positioning strips, the sliding fit between the connecting plate and the positioning grooves can play a positioning role for the hollow cylinder and cleaning components, which facilitates installation and disassembly.

[0016] Furthermore, the connecting plate has a first threaded hole inside one end of the positioning groove, and the top ring has a second threaded hole inside the positioning groove. A bolt is threadedly connected between the second threaded hole and the first threaded hole.

[0017] The beneficial effect of adopting the above-mentioned further solution is that when it is necessary to remove the cleaning assembly, the bolts are unscrewed to separate the bolts from the first threaded hole and the second threaded hole. Then, the cleaning assembly is pulled down to move it down until it is separated from the filter cartridge for maintenance. When it is necessary to reinstall the cleaning assembly after maintenance, the cleaning assembly is inserted from the bottom end of the filter cartridge, the gap between the outer scraper and the inner scraper is aligned with the wall of the filter cartridge, the outer wall of the connecting plate is aligned with the three positioning grooves, and then the bolts are reinstalled in the first threaded hole and the second threaded hole to complete the connection between the filter cartridge and the cleaning assembly.

[0018] Furthermore, the bolt has an internal hexagonal groove at the end furthest from the connecting plate.

[0019] The advantage of adopting the above-mentioned further solution is that by opening an internal hexagonal slot at the end of the bolt away from the connecting plate, the operator can use an internal hexagonal wrench that is compatible with the internal hexagonal slot to turn the bolt to loosen or tighten it.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This filter element mechanism for lubricating oil filtration, by incorporating a micro servo motor, drives a rotating rod to rotate when the micro servo motor is working. A connecting strip is installed at the bottom of the rotating rod, and a connecting seat is installed at the top of the connecting strip. The top of the connecting seat is connected to the outer scraper and the inner scraper via a threaded post. This allows the outer scraper to clean the outer wall of the filter cartridge, and the inner scraper to clean the inner wall of the filter cartridge. Furthermore, since several bristles are installed on the side of the inner scraper closest to the inner wall of the filter cartridge, and the outer diameter of the bristles is smaller than the inner diameter of the mesh of the filter cartridge, the bristles can be inserted into the mesh inside the filter cartridge for better cleaning. Additionally, the bristles are made of nylon, giving them a certain degree of hardness. This improves the cleaning effect. When the rotating rod rotates the connecting seat under the action of the connecting bar, the round rod moves inside the annular groove, so that the cleaning component will not easily shake during rotation, thus improving the cleaning stability. When it is necessary to remove the cleaning component, unscrew the bolts to separate them from the first and second threaded holes. Then pull the cleaning component down to move it down until it is separated from the filter cartridge for maintenance. Then, first rotate the outer scraper so that it can be removed from the connecting seat under the threaded connection of the third threaded hole and the threaded post at its bottom. Then rotate the inner scraper so that it can be removed from the connecting seat under the threaded connection of the third threaded hole and the threaded post at its bottom. Disassemble and replace the worn outer and inner scrapers. Attached Figure Description

A connecting seat 36 is connected between the ends of a pair of threaded posts 34 away from the outer scraper 31. The cleaning assembly 3 also includes a hollow cylinder 37. A rotating rod 39 is rotatably connected to the bottom end of the hollow cylinder 37. A connecting strip 310 is installed at the bottom end of the rotating rod 39. The upper end of the connecting strip 310 is connected to the connecting seat. The bottom end of 36 is fixedly connected by a rotating rod 39. When the rotating rod 39 rotates, a connecting strip 310 is installed at the bottom end of the rotating rod 39. A connecting seat 36 is installed at the upper end of the connecting strip 310, and the top end of the connecting seat 36 is connected to the outer scraper 31 and the inner scraper 32 through a threaded post 34. This allows the outer scraper 31 to clean the outer wall of the filter cartridge 16, and the inner scraper 32 to clean the inner wall of the filter cartridge 16. Simultaneously, since several bristles are installed on the side of the inner scraper 32 closest to the inner wall of the filter cartridge 16, and the outer diameter of the bristles is smaller than the inner diameter of the mesh of the filter cartridge 16, the bristles can... Inserting the cleaning component 3 into the mesh inside the filter cartridge 16 allows for better cleaning of the mesh. When the cleaning component 3 needs maintenance, first move the cleaning component 3 down until it separates from the filter cartridge 16. Then, rotate the outer scraper 31 so that it can be removed from the connecting seat 36 by the threaded connection between the third threaded hole 33 and the threaded post 34 at its bottom. Then, rotate the inner scraper 32 so that it can be removed from the connecting seat 36 by the threaded connection between the third threaded hole 33 and the threaded post 34 at its bottom. Disassemble and replace the worn outer scraper 31 and inner scraper 32.

[0029] 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.

[0030] Please refer to Figures 1-5. This utility model provides a technical solution: A hollow cylinder 37 is disposed inside the filter cylinder 16 near the upper end, and the central axis of the hollow cylinder 37 is collinear with the central axis of the filter cylinder 16. A micro servo motor 38 is installed inside the hollow cylinder 37. The output end of the micro servo motor 38 is connected to the rotating rod 39. The bottom ring 14 has an annular groove 15 on the side away from the filter cylinder 16. A round rod 35 is disposed inside the annular groove 15. The bottom end of the round rod 35 is fixedly connected to the upper end of the connecting seat 36. The outer wall of the round rod 35 slides with the inner wall of the annular groove 15. Several through holes are opened on the outer side of the filter cylinder 16. The outer diameter of the brush bristles is smaller than the inner diameter of the through holes. The brush bristles are evenly distributed and are made of nylon. By setting the micro servo motor 38, when the micro servo motor 38 works, it drives the rotating rod 39 to rotate. Since the bottom end of the rotating rod 39 is installed with a connecting rod 39... The upper end of the connecting strip 310 is equipped with a connecting seat 36, and the top of the connecting seat 36 is connected to the outer scraper 31 and the inner scraper 32 through the threaded post 34. This enables the outer scraper 31 to clean the outer wall of the filter cartridge 16 and the inner scraper 32 to clean the inner wall of the filter cartridge 16. Through the cooperation of the annular groove and the round rod 35, when the rotating rod 39 causes the connecting seat 36 to rotate under the action of the connecting strip 310, the round rod 35 moves inside the annular groove, so that the cleaning component 3 will not easily shake during rotation, thus improving the stability of cleaning. The filter cartridge 16 is made of stainless steel filter screen material. The through hole on the outside of the filter cartridge 16 allows lubricating oil to pass through the filter cartridge 16 smoothly. Since the outer diameter of the brush bristles is smaller than the inner diameter of the mesh of the filter cartridge 16, the brush bristles can be inserted into the mesh inside the filter cartridge 16, which can better clean the mesh. At the same time, the brush is made of nylon material, which gives the brush bristles a certain degree of hardness, thereby improving the cleaning effect.

[0031] 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.

[0032] Please refer to Figures 1-5. This utility model provides a technical solution: the connecting assembly 2 includes a connecting plate 21, the bottom end of which is fixedly connected to the upper end of the hollow cylinder 37. A plurality of positioning strips 12 are installed on the inner wall of the top ring 11, with six positioning strips 12 in total. The opposing sides of an adjacent pair of positioning strips 12 form a positioning groove. The outer wall of one end of the connecting plate 21 slides into the inner wall of the positioning groove, with three positioning grooves in total. A first threaded hole 22 is opened inside the end of the connecting plate 21 located in the positioning groove. A second threaded hole 13 is opened inside the top ring 11 located in the positioning groove. A bolt 23 is threaded between the second threaded hole 13 and the first threaded hole 22. An internal hexagonal groove is opened inside the bolt 23 at the end away from the connecting plate 21. Since there are six positioning strips 12, and a positioning groove is formed between an adjacent pair of positioning strips 12, the positioning groove... There are three of them. The sliding fit between the connecting plate 21 and the positioning groove can position the hollow cylinder 37 and the cleaning component 3, which is convenient for installation and disassembly. When the cleaning component 3 needs to be removed, the operator uses an Allen wrench that matches the Allen socket to turn the bolt 23 to loosen it, so that the bolt 23 is separated from the first threaded hole 22 and the second threaded hole 13. Then, the cleaning component 3 is pulled down to move it down until it is separated from the filter cartridge 16 for maintenance. When the cleaning component 3 needs to be reinstalled after maintenance, the cleaning component 3 is inserted from the bottom end of the filter cartridge 16. The gap between the outer scraper 31 and the inner scraper 32 is aligned with the cylinder wall of the filter cartridge 16, and the outer wall of the connecting plate 21 is aligned with the three positioning grooves. Then, the bolt 23 is reinstalled in the first threaded hole 22 and the second threaded hole 13 to complete the connection between the filter cartridge 16 and the cleaning component 3.

[0033] Specifically, the working principle of this filter element mechanism for lubricating oil filtration is as follows: During use, the filter cartridge 16 is made of stainless steel filter screen. The through-holes on the outside of the filter cartridge 16 allow lubricating oil to smoothly enter the filter cartridge 16 from the outside and flow out from the bottom. After filtration is complete, the filter cartridge 16 needs to be cleaned. Then, the micro servo motor 38 is activated to drive the rotating rod 39 to rotate. A connecting strip 310 is installed at the bottom of the rotating rod 39, and a connecting seat is installed at the upper end of the connecting strip 310. 36, and the top of the connecting seat 36 is connected to the outer scraper 31 and the inner scraper 32 via a threaded post 34, so that the outer scraper 31 cleans the outer wall of the filter cartridge 16, and the inner scraper 32 cleans the inner wall of the filter cartridge 16. At the same time, since several bristles are installed on the side of the inner scraper 32 near the inner wall of the filter cartridge 16, and the outer diameter of the bristles is smaller than the inner diameter of the mesh of the filter cartridge 16, the bristles can be inserted into the mesh inside the filter cartridge 16, which can better clean the mesh. The bristles are made of nylon. This gives the bristles a certain degree of hardness, thereby improving the cleaning effect. When the rotating rod 39 rotates the connecting seat 36 under the action of the connecting bar 310, the round rod 35 moves inside the annular groove, so that the cleaning component 3 will not easily shake during rotation, improving the cleaning stability. When it is necessary to remove the cleaning component 3, the operator uses an internal hex wrench that is compatible with the internal hex socket to turn the bolt 23, unscrew the bolt 23 so that the bolt 23 is separated from the first threaded hole 22 and the second threaded hole 13, and then pull the cleaning component 3 down so that the cleaning component 3 moves down until it is separated from the filter cartridge 16 for maintenance. Then, first rotate the outer scraper 31 so that it can be removed from the connecting seat 36 under the threaded connection of the third threaded hole 33 and the threaded post 34 at its bottom. Then rotate the inner scraper 32 so that it can be removed from the connecting seat 36 under the threaded connection of the third threaded hole 33 and the threaded post 34 at its bottom. The worn outer scraper 31 and inner scraper 32 are disassembled and replaced.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. Furthermore, since this application is mainly used to protect mechanical devices, the control methods and circuit connections will not be explained in detail in this application.
