Abstract
Description
Technical Field
[0001] This invention relates to the field of filtration, specifically to a combined filter element for a coalescing separator. Background Technology
[0002] Combined filter elements for coalescing separators, especially coalescing separator filter elements, are a type of high-efficiency and precision filtration equipment, widely used in various industrial fields that require oil-water separation or removal of impurities from fluids.
[0003] A combination filter element is a filter element that combines multiple filter materials and technologies. It can be combined with filter layers of different materials, filtration precision, and structures as needed to achieve multi-stage filtration and efficient separation. Depending on the application scenario and filtration requirements, combination filter elements can be divided into various types, such as oil-water separation filter elements, gas purification filter elements, and precision filter elements.
[0004] Patent application publication number CN217773435U discloses a combined filter element for an aviation kerosene coalescing separator. This component allows for easy fixing and disassembly of the combined filter element. When one of the coalescing filter element or the separating filter element is damaged, it can be replaced individually, avoiding waste of raw materials. In addition, this component makes it more convenient to replace the coalescing filter element. Since the coalescing filter element needs to be replaced frequently, this improves the practicality of the device.
[0005] In existing technologies, when a filter element is in direct contact with water for filtration, it can effectively intercept impurities such as rust and mud in the water. However, this process causes the filter element's filtration performance to gradually decline and it to be damaged by the constant impact of impurities, thereby reducing the overall service life of the filter element. Therefore, we need a coalescing separator with a combined filter element to solve the problem of impurities in the water impacting the filter element, which can reduce the impact of impurities in the water on the filter element.

[0029] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0030] Example 1, please refer to Figure 1 - Figure 11 This invention provides a combined filter element technical solution for a coalescing separator: the combined filter element for a coalescing separator includes: a filter element body 1, an installation mechanism is provided inside the filter element body 1, and a protective mechanism is provided below the installation mechanism. The installation mechanism includes an installation plate 3, the outer wall of the installation plate 3 is fixedly connected to the inner wall of the installation frame 2, the installation plate 3 has a circular hole on both outer walls that are connected, an installation seat 23 is fixedly connected to the middle of the top outer wall of the installation plate 3, a handle 21 is rotatably connected inside the installation seat 23, a pull rope 22 is fixedly connected to the outer wall of the handle 21, a limit block 25 is fixedly connected to the outer wall of one end of the six pull ropes 22, a storage groove is provided on the outer wall of the installation frame 2, the inside of the storage groove is movably inserted into the outer wall of the limit block 25, a return spring 28 is fixedly connected to the outer wall of one side of the six limit blocks 25, the inside of the return spring 28 is movably sleeved into the outer wall of the pull rope 22, and a limit groove 24 is provided on the inner wall of the filter element body 1, the inside of the limit groove 24 is movably inserted into the outer wall of the limit block 25.
[0031] After the protective mechanism is inserted into the filter element body 1, the operator can hold the two sides of the mounting plate 3 and rotate it. Then, by rotating the mounting plate 3, the mounting bracket 2 can drive the limiting block 25 to rotate along the inner wall of the filter element body 1. When the limiting block 25 is aligned with the limiting groove 24, the limiting block 25 can be pushed into the limiting groove 24 for fixation under the action of the return spring 28, so that the protective mechanism is fixed inside the filter element body 1. At this time, the protective mechanism works.
[0032] In Example 2, based on Example 1, the protection mechanism includes a mounting bracket 2. The outer wall of the mounting bracket 2 is in movable contact with the inner wall of the filter element body 1. The outer wall at the bottom of the mounting bracket 2 has a threaded groove 29. An adsorption plate 26 is threadedly connected inside the threaded groove 29. A limiting seat 27 is movably inserted into the outer wall at the bottom of the adsorption plate 26. The lower part of the inner wall of the filter element body 1 is fixedly connected to the outer wall at the bottom of the limiting seat 27.
[0033] The adsorption plate 26 intercepts impurities inside the water, preventing them from being directly transported to the filter element body 1, which could damage the filter element body 1, reduce its filtration efficiency and service life. Conversely, the adsorption plate 26 blocks impurities in the water before they reach the filter element body 1, thus protecting its normal operation, reducing its burden, and extending its service life.
[0034] In Example 3, based on Example 2, a mounting plate 39 is fixedly connected to the inner wall of the limiting seat 27. A socket 31 is fixedly connected to the middle of the top outer wall of the mounting plate 39. The mounting plate 39 has a circular hole on both outer walls that are connected. A mounting bracket 2 33 is rotatably connected inside the rotating groove 35. A magnetic plate 1 34 is fixedly connected inside the mounting bracket 2 33. A mounting bracket 37 is rotatably connected inside the rotating groove 35. A magnetic plate 2 38 is fixedly connected inside the mounting bracket 37. The outer wall of the top of the magnetic plate 2 38 and the outer wall of the bottom of the magnetic plate 1 34 are connected with the same pole and repulsed.
[0035] By adsorbing iron substances through magnetic plate 34 and magnetic plate 38, the iron impurities in the water, which have a certain hardness and sharpness, are prevented from directly impacting the filter body 1 and causing damage to the filter medium of the filter body 1. Accordingly, by setting magnetic plate 34 and magnetic plate 38, not only can the filtration efficiency of the filter body 1 be improved, but the risk of clogging of the filter body 1 is also reduced, and the service life of the filter body 1 is extended.
[0036] As magnetic plates 38 and 34 rotate inside the filter body 1, they form a dynamic magnetic field inside the filter body 1. This dynamic magnetic field is more effective than a static magnetic field in adsorbing iron substances in the water because the dynamic magnetic field can disturb the iron substances in the water, making them easier to be captured by magnetic plates 34 and 38. The presence of the dynamic magnetic field will accelerate the movement of iron substances in the water towards magnetic plates 34 and 38, thereby improving the filtration efficiency.
[0037] In Example 4, based on Example 3, a threaded rod 4 is fixedly connected inside the mounting rod 32. A temporary storage groove 41 is fixedly connected between the outer walls of the two threaded rods 4. Mounting plates 2 42 are threadedly connected to both sides of the outer walls of the threaded rods 4 on the temporary storage groove 41. A push rod 43 is rotatably connected to the outer wall of the mounting plate 2 42. A connecting seat 45 is rotatably connected to the outer wall of one end of the push rod 43. A square scraper 44 is fixedly connected to the outer wall of the bottom of the connecting seat 45. The outer walls of the four square scrapers 44 are slidably connected to the outer wall of the magnetic plate 1 34.
[0038] By pushing the square scraper 44 with the push rod 43 to slide on the magnetic plate 34, the iron material adsorbed on the outer wall of the magnetic plate 34 can be scraped off and collected in the temporary storage tank 41. This avoids the iron material adsorbed on the magnetic plate 34 forming a shielding layer when there is too much iron material, which would weaken the magnetic force of the magnetic plate 34 to the outside world. Correspondingly, the square scraper 44 can scrape off the iron material adsorbed on the magnetic plate 34, thereby maintaining the magnetic stability of the magnetic plate 34 and ensuring that the magnetic plate 34 can continuously and effectively adsorb ferromagnetic particles in the water.
[0039] In Example 5, based on Example 3, a mounting rod 32 is fixedly connected to the middle of the bottom outer wall of the mounting plate 3. The bottom outer wall of the mounting rod 32 is movably inserted into the inside of the socket 31. A rotating groove 35 is provided on the outer wall of the mounting rod 32. A circular groove is provided on the inner wall of the rotating groove 35. A ball bearing 36 is rotatably connected inside the circular groove.
[0040] When mounting brackets 2 (33) and 37 (37) rotate inside the rotating groove 35, the ball bearings 36 rotate accordingly, which reduces the friction between the rotating groove 35 and mounting brackets 2 (33) and 37 (37). This reduces the resistance to the rotation of mounting brackets 2 (33) and 37 (37) inside the rotating groove 35, making their rotation smoother and helping to extend the service life of mounting brackets 2 (33) and 37 (37) and the rotating groove 35.
[0041] In actual use, during operation, firstly, by inserting the adsorption plate 26 into the limiting seat 27, the mounting rod 32 can be inserted into the socket 31. At this time, when using the filter element body 1, the water entering the filter element body 1 can be intercepted by the adsorption plate 26, preventing impurities in the water from being directly transported to the filter element body 1, causing damage to the filter element body 1, reducing the filtration effect and service life of the filter element body 1. Correspondingly, the presence of the adsorption plate 26 can block impurities in the water in front of the filter element body 1, thereby protecting the normal operation of the filter element body 1, further reducing the burden on the filter element body 1, and extending the service life of the filter element body 1.
[0042] By inserting the mounting rod 32 into the socket 31, the first magnetic plate 34 and the second magnetic plate 38 can be fixed inside the filter body 1. The first magnetic plate 34 and the second magnetic plate 38 have a magnetic force that attracts ferrous objects. When there are ferrous substances in the water, the magnetic force will attract the ferrous particles in the water to adhere to the first magnetic plate 34 and the second magnetic plate 38. Due to the adsorption of ferrous substances by the first magnetic plate 34 and the second magnetic plate 38, the ferrous impurities in the water, which have a certain hardness and sharpness, are prevented from directly impacting the filter body 1 and causing damage to the filter medium of the filter body 1. Accordingly, by setting the first magnetic plate 34 and the second magnetic plate 38, not only can the filtration efficiency of the filter body 1 be improved, but the risk of clogging of the filter body 1 can also be reduced, thus extending the service life of the filter body 1.
[0043] Furthermore, through the repulsive action of like poles of magnetic plate 34 and magnetic plate 38, magnetic plate 38 drives the mounting bracket 37 to rotate, while magnetic plate 34 drives the mounting bracket 33 to rotate inside the rotating groove 35. Through the rotation of magnetic plate 38 and magnetic plate 34 inside the filter body 1, they will form a dynamic magnetic field inside the filter body 1. This dynamic magnetic field will adsorb iron substances in the water more effectively than a static magnetic field, because the dynamic magnetic field can disturb the iron substances in the water, making them easier to be captured by magnetic plate 34 and magnetic plate 38. The presence of the dynamic magnetic field will accelerate the movement speed of iron substances in the water towards magnetic plate 34 and magnetic plate 38, thereby improving the filtration efficiency.
[0044] When mounting brackets 37 and 33 rotate inside the rotating groove 35, the contact area between them and the rotating groove 35 is reduced by the ball bearings 36 inside the rotating groove 35. Furthermore, the rotation of the ball bearings 36 within the rotating groove 35 drives the ball bearings 36 to rotate as well, reducing friction between the rotating groove 35 and the mounting brackets 37. This reduces the resistance to the rotation of the mounting brackets 33 and 37 within the rotating groove 35, allowing them to rotate more smoothly and extending their service life relative to the rotating groove 35.
[0045] When the mounting bracket 2 33 rotates, it drives the square scraper 44 to rotate as well. Then, through the connection between the connecting seat 45 at the bottom of the square scraper 44 and the push rod 43, the rotation of the square scraper 44 drives the push rod 43 to rotate. Then, through the connection between the push rod 43 and the mounting plate 2 42, the rotation of the push rod 43 drives the mounting plate 2 42 to rotate on the threaded rod 4. Through the threaded connection between the threaded rod 4 and the mounting plate 2 42, the mounting plate 2 42 can move up and down on the threaded rod 4. Then, through the up and down movement of the mounting plate 2 42, the relationship between the push rod 43 and the mounting plate can be changed. The connection angle between the second 42 and the connecting seat 45 allows the push rod 43 to push the square scraper 44 to slide on the magnetic plate 34, thus scraping off the iron substances adsorbed on the outer wall of the magnetic plate 34 and collecting them inside the temporary storage tank 41. This avoids the iron substances adsorbed on the magnetic plate 34 forming a shielding layer when there is a lot of iron substances adsorbed on it, which would weaken the magnetic force of the magnetic plate 34 to the outside world. Correspondingly, the square scraper 44 can scrape off the iron substances adsorbed on the magnetic plate 34, thereby maintaining the magnetic stability of the magnetic plate 34 and ensuring that the magnetic plate 34 can continuously and effectively adsorb ferromagnetic particles in the water.
[0046] By rotating handle 21, the operator can wind the pull rope 22, shortening it. This shortening, combined with the connection between the pull rope 22 and the limiting block 25, pulls the limiting block 25 into the receiving groove inside the mounting bracket 2, releasing the fixing between the limiting block 25 and the limiting groove 24. Inserting the limiting block 25 into the limiting groove 24 allows the mounting bracket 2 to be placed inside the filter element body 1, preventing the adsorption plate 26 from shaking during operation. Conversely, fixing the mounting bracket 2 increases the stability of the adsorption plate 26 within the filter element body 1, reducing wear and fatigue caused by shaking.
[0047] After the limiting block 25 is released from the limiting groove 24, the operator can pull the handle 21 upward or hold the two sides of the mounting plate 3 and pull it upward. The upward movement of the handle 21 will cause the mounting plate 3 to move the mounting frame 2 upward, thereby removing the adsorption plate 26 and the mounting rod 32 from the inside of the filter body 1. This makes it easier to clean the impurities inside the adsorption plate 26 and the temporary storage tank 41. Since the adsorption plate 26 and the mounting frame 2 are threadedly connected, the adsorption plate 26 can be removed from the mounting frame 2 for replacement.
[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
