Description

Technical Field

[0001] This utility model relates to the field of magnetic filter technology, specifically a magnetic adsorption filter screen. Background Technology

[0002] Magnetic adsorption filters, also known as magnetic filters or magnetic field filters, are devices that use magnetic force to filter impurities. They are mainly used to remove ferromagnetic impurities from liquids or gases, improving product quality and purity.

[0003] Patent CN217594843U discloses a magnetic filter that improves the removal of ferromagnetic impurities while filtering fluids, relating to the field of filter technology. The magnetic filter includes a housing and a filter element, with the filter element disposed within the housing. The housing has a fluid inlet and a fluid outlet. A cavity between the housing and the filter element forms an outer filtration cavity. The fluid outlet communicates with the inner cavity of the filter element, and the fluid inlet communicates with the outer filtration cavity. The outer filtration cavity contains multiple magnetic rods arranged at intervals around the filter element, and a flow-guiding structure is provided to increase the contact time between the fluid and the magnetic rods. This technology offers better removal of ferromagnetic impurities and is particularly suitable for fluids with high viscosity.

[0004] However, the above technology still has the following problems:

[0005] The filter contains ferromagnetic impurities and other types of impurities. After using a magnetic rod to adsorb and clean the ferromagnetic impurities, a large amount of ferromagnetic impurities will adhere to the surface of the magnetic rod. At the same time, a significant amount of other impurities will also accumulate on the filter screen. To ensure the filtration effect of the magnetic filter, these impurities need to be cleaned regularly. Especially when there are many impurities on the filter screen, it will not only affect the filtration effect but also reduce filtration efficiency. Utility Model Content

[0007] This utility model provides the following technical solution: a magnetic adsorption filter screen, including a filter tank, a tank cover detachably connected to the filter tank, several limiting plates fixedly connected to the side of the tank cover, a fixing mechanism for fixing the limiting plates fixedly connected to the filter tank, four extrusion rods arranged in a circumferential array fixedly connected to the lower surface of the tank cover, an annular plate fixedly connected to the inner wall of the filter tank, a filter mechanism placed on the annular plate, several internally threaded tubes fixedly connected to the lower surface of the tank cover, threaded grooves opened on the outer wall of the internally threaded tubes, an adsorption component can be threadedly connected to the internally threaded tubes, a protective component is threadedly connected to the threaded grooves, and a cleaning component for cleaning the filter mechanism is installed on the tank cover.

[0008] Furthermore, the fixing mechanism includes two rotating blocks fixedly connected to the outer wall of the filter tank, a rotating shaft 1 rotatably connected between the two rotating blocks, a threaded rod fixedly connected to the rotating shaft 1, an internally threaded tube 2 threadedly connected to the threaded rod, and a knob fixedly connected to the upper end of the internally threaded tube 2.

[0009] Furthermore, the filtration mechanism includes an annular support plate adapted to the annular plate, a filter barrel is fixedly connected to the lower end of the annular support plate, the filter barrel is slidably connected to the inner wall of the annular plate, the periphery and bottom of the filter barrel are both filter plates, and the periphery and bottom are smoothly connected by an arc surface.

[0010] Furthermore, the adsorption assembly includes an externally threaded tube threaded onto an internally threaded tube, a placement bucket fixedly connected to the lower end of the externally threaded tube, a magnetic rod slidably connected between the placement bucket and the interior of the externally threaded tube, and a protective layer provided on the surface of the magnetic rod.

[0011] Furthermore, the protective component includes an internally threaded tube three threaded onto a threaded groove, an annular connecting plate fixedly connected to the lower end of the internally threaded tube three, and a protective bucket fixedly connected to the lower end of the annular connecting plate, the inner diameter of the protective bucket being larger than the outer diameter of the placement bucket.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1 to 6 A magnetic adsorption filter includes a filter tank 1, a detachable lid 2 connected to the filter tank 1, several limiting plates 3 fixedly connected to the side of the lid 2, a fixing mechanism for fixing the limiting plates 3 fixedly connected to the filter tank 1, four extrusion rods 4 arranged in a circumferential array fixedly connected to the lower surface of the lid 2, an annular plate 5 fixedly connected to the inner wall of the filter tank 1, a filter mechanism placed on the annular plate 5, several internally threaded tubes 6 fixedly connected to the lower surface of the lid 2, threaded grooves 7 opened on the outer wall of the internally threaded tubes 6, adsorption components can be threadedly connected to the internally threaded tubes 6, protective components are threadedly connected to the threaded grooves 7, and a cleaning component for cleaning the filter mechanism is installed on the lid 2.

[0025] The magnetic adsorption filter in this invention is similar in structure to existing magnetic filters, such as the magnetic filter disclosed in patent CN217594843U. The main improvement of this invention lies in its ease of installation and disassembly of the magnetic rod 17 and the filter barrel 14. Furthermore, during use, it can scrape away impurities adhering to the inner wall of the filter barrel 14, preventing impurities from clogging the filter holes and thus ensuring the filtration effect. Figures 1 to 6As shown, in use, the magnetic adsorption filter of this utility model is first placed on the annular plate 5 on the inner wall of the filter tank 1. Then, the four pressing rods 4 on the lower surface of the tank cover 2 slide down along the inner wall of the filter tank 1 until the tank cover 2 abuts against the upper end of the filter tank 1. A sealing ring is provided at the connection between the tank cover 2 and the filter tank 1. At this time, the lower ends of the four pressing rods 4 abut against the annular support plate 13 on the filter mechanism, thereby fixing the filter mechanism. Then, the fixing mechanism is connected to the limiting plate 3 to fix the tank cover 2. External fluid is then connected to the upper part of the filter tank 1 through the flange. Filtration can be performed by connecting the inlet pipe. After the fluid enters the interior of the filter tank 1, the magnetic rod 17 will adsorb the ferromagnetic impurities in the fluid, so that the ferromagnetic impurities are adsorbed on the outer surface of the protective barrel 20, while other impurities are filtered out by the filter barrel 14. During the filtration process, the driver 22 can be started, which will cause the rotating shaft 23 to rotate, thereby causing the stirring plate 24 to rotate slowly. The scraper 25 on the surface of the stirring plate 24 scrapes the inner wall of the filter barrel 14 to prevent impurities from staying on the inner wall of the filter barrel 14 for a long time, causing the filter holes to be blocked and affecting the filtration efficiency.

[0026] like Figure 6 As shown, the fixing mechanism includes two rotating blocks 8 fixedly connected to the outer wall of the filter tank 1. A rotating shaft 9 is rotatably connected between the two rotating blocks 8. A threaded rod 10 is fixedly connected to the rotating shaft 9. An internally threaded tube 11 is threadedly connected to the threaded rod 10. A knob 12 is fixedly connected to the upper end of the internally threaded tube 11.

[0027] Specifically, by rotating knob 12, the internal threaded tube 11 moves upward along the threaded rod 10, causing the lower surface of knob 12 to gradually move away from the upper surface of the limiting plate 3. Then, by rotating the internal threaded tube 11 and the threaded rod 10 downward along with the rotating shaft 9, the fixing effect on the can lid 2 can be released. The can lid 2 can be removed and placed at an angle, so that the front end of the limiting plate 3 and the front end of the squeezing rod 4 touch the ground. This facilitates the disassembly of the protective components, the cleaning components, and the removal of the filter mechanism from the inside of the filter can 1.

[0028] like Figure 2 As shown, the filtration mechanism includes an annular support plate 13 adapted to the annular plate 5. A filter barrel 14 is fixedly connected to the lower end of the annular support plate 13. The filter barrel 14 is slidably connected to the inner wall of the annular plate 5. The periphery and bottom of the filter barrel 14 are both filter plates, and the periphery and bottom are smoothly connected by an arc surface.

[0029] Specifically, the annular support plate 13 is fixed by the clamping action of the extrusion rod 4 and the annular plate 5, and the filter barrel 14 is slidably connected to the inner wall of the annular plate 5, which enhances stability. The periphery and bottom of the filter barrel 14 are both filter plates, and the periphery and bottom are connected by a smooth arc surface, which increases the filtration area. At the same time, the smooth arc surface connection will not have any dead corners, which facilitates subsequent cleaning work.

[0030] like Figure 5 As shown, the adsorption assembly includes an externally threaded tube 15 that is threaded onto an internally threaded tube 6. A placement bucket 16 is fixedly connected to the lower end of the externally threaded tube 15. A magnetic rod 17 is slidably connected between the placement bucket 16 and the interior of the externally threaded tube 15. A protective layer is provided on the surface of the magnetic rod 17.

[0031] Specifically, after removing the protective components, rotating the placement bucket 16 will cause the external threaded tube 15 to rotate, thereby removing the external threaded tube 15 and the placement bucket 16 so that the magnetic rod 17 can be removed and replaced. The reverse operation can be performed to re-fix it.

[0032] like Figure 5 As shown, the protective assembly includes an internally threaded tube 18 threaded onto a threaded groove 7. An annular connecting plate 19 is fixedly connected to the lower end of the internally threaded tube 18. A protective barrel 20 is fixedly connected to the lower end of the annular connecting plate 19. The inner diameter of the protective barrel 20 is larger than the outer diameter of the placement barrel 16.

[0033] Specifically, after removing the can lid 2, rotating the protective barrel 20 will cause the internal threaded tube 3 18 to rotate and detach from the threaded groove 7. The protective barrel 20 can then be moved away, gradually moving away from the magnetic rod 17, thus no longer exerting an attractive force on the ferromagnetic material, making it easier to clean the ferromagnetic material adhering to the surface of the protective barrel 20.

[0034] like Figure 5 As shown, a sealing gasket 21 is fixedly connected to the upper end of the internally threaded tube 18.

[0035] Specifically, the sealing gasket 21 can provide a good seal between the internal threaded pipe 3 18 and the can lid 2, preventing fluid from entering the interior of the threaded groove 7, etc.

[0036] like Figure 4 As shown, the cleaning assembly includes a driver 22 fixedly connected to the upper surface of the can lid 2, a rotating shaft 23 fixedly connected to the output end of the driver 22, a stirring plate 24 fixedly connected to the lower end of the rotating shaft 23, and a scraper 25 fixedly connected to the outer wall of the stirring plate 24.

[0037] Specifically, when filtering fluid, the driver 22 can be started, which causes the rotating shaft 23 to rotate, thereby causing the stirring plate 24 to rotate slowly. The scraper 25 on the surface of the stirring plate 24 scrapes the inner wall of the filter barrel 14 to prevent impurities from staying on the inner wall of the filter barrel 14 for a long time, causing the filter holes to be blocked and affecting the filtration efficiency.

[0038] Although the present invention 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 invention should be included within the protection scope of the present invention.
