Description

Technical Field

[0001] This utility model relates to the field of microporous filter technology, specifically a reflux microporous filter that facilitates impurity removal. Background Technology

[0002] In many industries such as chemical, pharmaceutical, and food and beverage, reflux microporous filters can effectively trap tiny particles, impurities and microorganisms in liquids due to their high filtration efficiency, thereby achieving the purification and upgrading of liquids. They are widely used in the filtration process of various liquids. Traditional reflux microporous filters usually use filter cartridges as the filter medium. The liquid is driven by pressure to pass through the micropores of the filter cartridge, trapping impurities on the surface or inside of the filter cartridge.

[0003] However, in actual use, existing reflux microporous filters have many problems. As filtration continues, impurities will gradually accumulate on the surface and inside of the filter element, causing the filter element to become clogged and the filtration efficiency to drop significantly. In order to maintain the filtration effect, the filter element needs to be cleaned or replaced frequently. However, the structural design of the existing filter makes the process of disassembling and installing the filter element cumbersome and consumes a lot of manpower and time.

[0004] According to the description of a reflux microporous filter published on the patent website (authorization announcement number: CN218339101U), the reflux microporous filter includes "filter box, microporous filter element" etc., to achieve filtration.

[0005] Regarding the above description, the applicant believes the following issues exist:

[0006] This reflux microporous filter uses a filter box and microporous filter element to perform filtration. During use, the filter works by filtering through the microporous filter element, and the spray pipe can only clean the bottom of the microporous filter element. After prolonged use, a large amount of impurities will accumulate on the top of the microporous filter element, which cannot be cleaned. Furthermore, the microporous filter element cannot be replaced or disassembled for cleaning, affecting the impurity removal effect. Therefore, this filter needs to be improved. Utility Model Content

[0010] Preferably, the bottom of the threaded rod is rotatably connected to the bottom of the fixed frame, and the connecting arm is slidably connected to the inside of the fixed frame, so as to facilitate the movement of the sealing cover by the connecting arm.

[0011] Preferably, the fixing column is fixedly connected to the top of the base, and through holes are respectively opened inside the fixing column, at the bottom and inside the base. The through hole at the bottom of the fixing column and the through hole inside the base correspond to each other, so that the liquid filtered by the filter element can enter the bottom of the filter box and be discharged through the drain pipe under the action of the through holes.

[0012] Preferably, the fixing frame has an internal water inlet hole, which is arc-shaped. The connecting shaft and nut are made of stainless steel, which has good corrosion resistance and can resist the erosion of various chemical substances, including acid and alkali media in industrial environments.

[0013] Preferably, there are seven sets of connecting shafts, filter elements, fixing columns, and nuts. The seven sets of connecting shafts, filter elements, fixing columns, and nuts are symmetrically distributed at the bottom of the fixing frame, which facilitates the passage of seven sets and can improve the filtration effect.

[0014] Preferably, the reflux mechanism includes a reflux pipe, which is fixedly connected to the inside of the filter box. A pump body is fixedly connected to the periphery of the reflux pipe.

[0016] Compared with the prior art, this utility model provides a reflux microporous filter that facilitates impurity removal, and has the following beneficial effects:

[0017] 1. This easy-to-remove reflux microporous filter features a filtration mechanism where the filter element is slidably connected to the inside of the fixed frame via a connecting shaft and secured with a nut. This allows for filter element installation, ensuring a stable connection between the filter element and the sealing cover. A servo motor drives a threaded rod to rotate, causing the sealing cover to move downwards, which in turn slides the filter element onto the outside of the fixed column until the bottom of the filter element contacts the top of the base. Simultaneously, the threaded rod allows for the lifting and lowering of the sealing cover, facilitating quick and easy opening of the filter box for replacement or cleaning of the internal filter element. This significantly improves the convenience of impurity removal and maintenance. The arc-shaped water inlet hole inside the fixed frame helps guide the liquid to flow evenly into the filter element, making the filtration process more thorough and efficient. It also reduces the impact of liquid on the filter element, lowering component wear. Seven symmetrically distributed connecting shafts, filter elements, fixed columns, and nuts increase the filtration area, effectively intercepting impurities and improving filtration efficiency to meet large-scale filtration needs.

[0018] 2. This easy-to-remove reflux microporous filter, through the set reflux mechanism, has a reflux pipe fixedly connected inside the filter box, with the top right side located at the top of the fixed frame. In conjunction with the operation of the pump, it can send the insufficiently filtered liquid back to the filter box for secondary filtration, effectively improving the filtration accuracy and quality, and ensuring that the filtered liquid reaches a higher purity standard. The pump is firmly installed through the fixed seat and support frame, ensuring stable operation of the reflux process. Attached Figure Description

[0030] This utility model provides the following technical solution:

[0031] Example 1

[0032] Please see Figure 1-7 This utility model provides a technical solution: a reflux microporous filter that is easy to remove impurities, including a support frame 1, a filter mechanism 2 is provided inside the support frame 1, and a reflux mechanism 3 is provided on the left side of the filter mechanism 2;

[0033] The filtration mechanism 2 includes a filter box 21, which is fixedly connected to the inner side of the support frame 1. A drain pipe 23 is fixedly connected to the bottom of the filter box 21, and a valve 24 is fixedly connected to the outside of the drain pipe 23. A base 22 is fixedly connected to the bottom of the filter box 21. A mounting bracket 25 is fixedly connected to the rear side of the filter box 21. A fixing frame 26 is fixedly connected to the top of the mounting bracket 25. A servo motor 28 is fixedly connected to the top of the fixing frame 26. A threaded rod 27 is fixedly connected to the bottom of the servo motor 28. The threaded rod 27 has threads on its outer periphery. A connecting arm 29 is connected, and a sealing cover 291 is fixedly connected to the inner side of the connecting arm 29. The sealing cover 291 is slidably connected to the top of the filter box 21. A water inlet pipe 292 is fixedly connected to the top of the sealing cover 291. A fixing bracket 293 is fixedly connected to the top of the inner side of the sealing cover 291. A connecting shaft 294 is slidably connected inside the fixing bracket 293. A filter element 295 is fixedly connected to the bottom of the connecting shaft 294. A fixing post 296 is slidably connected inside the filter element 295. A nut 297 is threadedly connected to the outer side of the connecting shaft 294.

[0034] The bottom of the threaded rod 27 is rotatably connected to the bottom of the fixed frame 26, and the connecting arm 29 is slidably connected to the inside of the fixed frame 26, so that the sealing cover 291 can be moved by the connecting arm 29. The fixed column 296 is fixedly connected to the top of the base 22. The fixed column 296, the bottom and the base 22 are respectively provided with through holes. The through hole at the bottom of the fixed column 296 and the through hole inside the base 22 correspond to each other, so that the liquid filtered by the filter element 295 can enter the bottom of the filter box 21 and be discharged through the drain pipe 23 under the action of the through holes.

[0035] The mounting bracket 293 has an internal water inlet hole, which is arc-shaped. The connecting shaft 294 and nut 297 are both made of stainless steel. Stainless steel has good corrosion resistance and can resist the erosion of various chemicals, including acid and alkali media in industrial environments. There are seven sets of connecting shaft 294, filter element 295, fixing column 296 and nut 297. The seven sets of connecting shaft 294, filter element 295, fixing column 296 and nut 297 are symmetrically distributed at the bottom of the mounting bracket 293 to facilitate the passage of the seven sets and improve the filtration effect.

[0036] Example 2

[0037] Please see Figure 1-7 Furthermore, based on Embodiment 1, the reflux mechanism 3 includes a reflux pipe 34, which is fixedly connected to the inside of the filter box 21. A pump body 33 is fixedly connected to the outside of the reflux pipe 34. A fixed seat 32 is fixedly connected to the bottom of the pump body 33. A support frame 31 is fixedly connected to the rear top of the fixed seat 32. The support frame 31 is fixedly connected to the left side of the mounting frame 25. The top right side of the reflux pipe 34 is fixedly connected to the inside of the filter box 21 and is located at the top of the fixed frame 293, which facilitates the re-transport of the medium that needs to be refluxed to the top of the fixed frame 293 for filtration through the reflux pipe 34.

[0038] In actual operation, when this device is used and filtration is required, first move the sealing cover 291 away from the top of the filter box 21. The filter element 295 is slidably connected to the inside of the fixing frame 293 through the connecting shaft 294, and the connecting shaft 294 is fixed by the nut 297. This allows the filter element 295 to be installed, ensuring a stable relationship between the filter element 295 and the sealing cover 291. After fixing, the servo motor 28 drives the threaded rod 27 to rotate, causing the connecting arm 29 to move the sealing cover 291 downwards. When the sealing cover 291 moves, it will move the fixing frame 293 and the fixed filter element 295, allowing the filter element 295 to slide and connect to the outside of the fixing column 296 until the bottom of the filter element 295 contacts the top of the base 22. At this point, the sealing cover 291 can slide and connect to the top of the filter box 21, sealing the filter box 21.

[0039] At this point, the external conveying pipe can be connected to the inlet pipe 292, and the external collection pipe can be connected to the drain pipe 23. The liquid enters the filter box 21 through the inlet pipe 292. The arc-shaped water inlet hole inside the fixing frame 293 helps to guide the liquid to flow evenly into the filter element 295, making the filtration process more thorough and efficient. At the same time, it reduces the impact of the liquid on the filter element 295 and reduces component wear. Under the action of the filter element 295, the liquid can be filtered. The seven sets of symmetrically distributed connecting shafts 294, filter elements 295, fixing columns 296 and nuts 297 increase the filtration area, which can efficiently intercept impurities, improve the filtration effect, and meet the needs of large-scale filtration.

[0040] During the filtration process, the return pipe 34 is fixedly connected inside the filter box 21, and its top right side is located on the top of the fixed frame 293. In conjunction with the operation of the pump body 33, the liquid that has not been fully filtered can be sent back to the filter box 21 for secondary filtration, which effectively improves the accuracy and quality of filtration and ensures that the filtered liquid reaches a higher purity standard.

[0041] The fixed column 296 and the base 22 have through holes inside and at the bottom, ensuring that the liquid can enter the bottom of the filter box 21 stably and smoothly during the filtration process. When the valve 24 is opened, the filtered liquid can be discharged through the drain pipe 23 for subsequent processing. When the filter element 295 needs to be replaced or cleaned, the sealing cover 291 is moved upward by the threaded rod 27, so that the filter element 295 is completely removed from the filter box 21. The nut 297 is removed, and the filter element 295 can be replaced and cleaned.
