DETAILED DESCRIPTION

[0044] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0045] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0046] Example 1

[0047] like Figure 1-5 As shown, an embodiment of the present invention provides a novel vibration-resistant cylindrical air filter structure, which is assembled from four modules, namely, an air inlet 1, an air inlet filter guide device 2, an anti-vibration filter element 3, and a filter cartridge 4. The air inlet 1 and the air inlet filter guide device 2 are locked by fasteners 226, and the air inlet filter guide device 2 is inserted into the filter cartridge 4 and is also locked by fasteners 226. The side wall 223 of the air inlet filter guide device 2 coincides with the first cylinder wall 41 of the filter cartridge 4. The vibration-resistant filter element 3 is inserted into the filter cartridge 4 from the bottom end, the positioning column 38 of the filter element 3 coincides with the positioning column slide 47 of the filter cartridge 4, and the limit pin 381 coincides with the limit pin slot 48 and is locked, thereby fixing the position of the vibration-resistant filter element 3 and the filter cartridge 4 together. Figure 1 The two dotted arrows in the figure are the air flow trajectories in and out of the filter.

[0048] The air inlet 1 is the top cover of the filter. The interior is empty to ensure airflow in. It fits with the cover plate 222 of the air inlet filter guide device 2.

[0049] The primary screening filter 21 is a part of the air intake filter guide device 2, fixed to the upper part of the device, removable and replaceable, and is in a circular ring shape, consisting of an outer ring frame 211, a metal mesh layer 212, and an inner ring frame 213. The metal mesh layer 212 is a filter filament mesh with two or more layers, which can preliminarily filter impurities such as fluff, hair, dust, and small dust particles in the incoming air.

[0050] There are two fasteners (fastener 226 (a), fastener 226 (b)) on both sides of the uppermost cover plate 222 of the air intake filter guide device 2, which have a locking function and are used to fix the air intake filter guide device 2 and the air inlet 1 and the filter cartridge 4.

[0051] The middle of the cover plate 222 is sunken downward to form a circular ring shape, revealing the side wall 223 and eight beams 224. The primary screening filter 21 can be placed on it. The primary screening filter 21 is aligned and fixed, and is flush with the cover plate 222. In order to ensure smooth air entry, a guide cone 221 is added for simple diversion, so that air can smoothly enter the primary screening filter 21. The outer wall barrier of the side wall 223 fits the first cylinder wall 41 of the filter cartridge 4 to ensure the vibration resistance and stability of the cylindrical filter, and a threaded structure can also be added for fixing and fitting. A sealing ring is added to increase airtightness. The guide cone 225 pushes the air onto the sloped side wall 42 of the filter cartridge 4, and the function realization and coordination are described in the following description of the filter cartridge 4.

[0052] The vibration-resistant filter element 3 includes four filter element structures (a first filter element 31 , a second filter element 32 , a third filter element 33 and a fourth filter element 34 ), a filter element outer cylinder structure 35 , a positioning column 38 , a limit pin 381 , a lock buckle 39 , a filter inner chamber 36 and an air outlet 37 .

[0053] The four filter element structures (the first filter element 31, the second filter element 32, the third filter element 33 and the fourth filter element 34), taking the first filter element 31 as an example, include a hexagonal fixed support frame 311 and a hexagonal filter element material 312. Since these materials are the core of the filtration and need to be protected, their structural stability can be greatly increased by designing or compressing these materials into a hexagonal structure, and they are fixed with a hexagonal fixed support frame 311, so that their vibration resistance and structural stability are greatly enhanced, and the life of the filter element is extended.

[0054] The hexagonal fixed support frame 311 is welded with multiple triangular stable structures, the top and bottom are similar to spider web structures, and the sides are fixed at the diagonal lines to enhance the structural stability. The hexagonal fixed support frame 311 is not a completely welded structure, and the middle can be opened to facilitate the replacement of the hexagonal filter element material 312.

[0055] The four filter element structures (the first filter element 31, the second filter element 32, the third filter element 33 and the fourth filter element 34) are respectively equipped with four different hexagonal filter element materials 312, and the filtering capacity increases layer by layer. The first layer can be selected to be non-woven fabric or glass fiber, the second layer can be selected to use electret filter materials, and the third and fourth layers can use polypropylene (PP) and polyethylene terephthalate (PET) composite high-efficiency filter paper, glass fiber high-efficiency filter paper, nano-silicon dioxide (SiO2+ZnO), electrospun nanofiber and other high-efficiency materials to filter toxic gases containing heavy metals, formaldehyde, etc.

[0056] The filter element outer cylinder structure 35 is the main structure of the filter element 3. There are four hexagonal grooves (first hexagonal groove 351, second hexagonal groove 352, third hexagonal groove 353 and fourth hexagonal groove 354) on the structure, which correspond to the four nested filter element structures (first filter element 31, second filter element 32, third filter element 33 and fourth filter element 34), and there are four protruding filter material support frames (first filter material support frame 3511, second filter material support frame 3521, third filter material support frame 3531 and fourth filter material support frame 3541) under each groove, and these grooves and filter material support frames jointly fix the corresponding filter element structure.

[0057] There are six positioning posts 38 on the filter element outer cylinder structure 35, three on each side, symmetrically distributed. The positioning posts 38 are consistent with the positioning post slideway 47 of the filter cartridge 4, and are used to fix and stabilize the position of the vibration-resistant filter element 3 in the filter cartridge 4 to enhance the structural performance.

[0058] There are two limit pins 381, one on each side, at the bottom of the outer cylinder structure 35, connected to the positioning column 38. Since the positioning column 38 can only limit the anti-vibration filter element 3 from rotating left and right, the limit pin 381 can limit the up and down position of the anti-vibration filter element 3. The two together play the role of fixing the anti-vibration filter element 3. In addition, the limit pin 381 can be locked after it matches the limit pin slot 48. The positioning column 38 of the anti-vibration filter element 3 matches the positioning column slide 47 of the filter cartridge 4, and the limit pin 381 matches and locks with the limit pin slot 48, thereby fixing the position of the anti-vibration filter element 3 and the filter cartridge 4 together.

[0059] There are four locks 39, two pairs each. When the locks 39 are opened, the filter element outer cylinder structure 35 is split into two halves, which is convenient for replacing the four filter element structures (the first filter element 31, the second filter element 32, the third filter element 33 and the fourth filter element 34). When the locks 39 are closed, the filter element outer cylinder structure 35 is closed. The six positioning columns 38 and the two limit pin slots 48 are all on one side of the filter element outer cylinder structure 35.

[0060] The filter cartridge 4 includes a first cartridge wall 41, a sloped cartridge wall 42, a dirt collection groove 43, a thick wall 44, an inlet 45, a dirt outlet 46, a positioning column slide 47, a limit pin slot 48, a cartridge inner cavity 49 and a cavity 491 for loading the anti-vibration filter element 3.

[0061] The first cylinder wall 41 matches the side wall 223 of the air intake filtering and guiding device 2 .

[0062] The sloped cylinder wall 42 is wide at the top and narrow at the bottom. When the guide cone 225 and the sloped cylinder wall 42 have different inclination angles, the formed gas channel gradually narrows, the gas flow rate increases, and smaller dust, moisture, oil and other impurities in the air are pushed onto the sloped cylinder wall 42. The inclined cylinder wall is more likely to strengthen the inertia of impurities such as oil than the vertical cylinder wall, making it easier for the impurities to slide down the slope into the dirt collection tank 43.

[0063] The thick wall 44 can lower the center of gravity of the filter cartridge 4 , play a role in stabilization and vibration reduction, and protect the filter element 3 .

[0064] The dirt collection tank 43 is a concave tank body. The depth of the tank body can be further deepened to ensure that small dust, water, oil and other impurities sliding down from the slope cylinder wall 42 are not easy to swing out of the dirt collection tank 43. At the same time, a suitable liquid can be added to the collection tank 43 according to needs to ensure that the sliding dust is more difficult to swing out. When the tank body is deeper, the added liquid will also be more difficult to vibrate out of the concave dirt collection tank 43.

[0065] Open the sewage outlet 46 gate regularly to discharge sewage or wastewater.

[0066] The inlet 45 can be opened to add a suitable liquid into the dirt collection tank 43 or clean water can be added to clean the dirt collection tank 43 .

[0067] The positioning column slideway 47 and the limiting pin slot 48 respectively match and lock with the positioning column 38 and the limiting pin 381 of the filter element 3 to fix the positions of the vibration-resistant filter element 3 and the filter cartridge 4.

[0068] The filter cartridge inner cavity 49 is used to store the air intake filter guide device 2 and air flow.

[0069] The cavity 491 is used to load the vibration-resistant filter element 3 .

[0070] Sealing rings can be added to all structural contacts as required to ensure the sealing and structural stability of the filter device.

[0071] When the present invention is working: air or other gas enters from the air inlet 1, the air is subjected to the first level of preliminary filtration through the air inlet filter guide device 2, the gas is compressed and pushed into the filter cartridge 4, the guide cone 225 at the bottom of the air inlet filter guide device 2 has a different inclination angle from the sloped cylinder wall 42, the formed gas channel gradually narrows, the gas flow rate increases, and smaller dust, moisture, oil and other impurities in the air are pushed to the sloped cylinder wall 42 and slide down the slope into the dirt collection tank 43. This process forms the second level of filtration. The air undergoes Brownian motion and enters the anti-vibration filter element 3, and undergoes the third level of H13 filtration through four filter elements of different materials. The purified air finally flows out from the air outlet 37. The entire air filtration process is completed through the overall structure that matches and stabilizes each other. The hexagonal structure of the filter cartridge and the filter element, and the structure of the filter cartridge and the filter cartridge barrel complement each other, which improves the smoothness of the airflow and enhances the large air volume processing capacity; as well as the multi-level filtration structure, improves the filtration efficiency and extends the life of the filter element. The addition of the guide cone and the design of the sloped cylinder wall jointly promote the separation of impurities. Compared with the existing cylindrical air filter technology, the hexagonal filter element structure and the sloped cylinder wall design are more innovative. In order to facilitate the application in special environments such as vibration and impact, a new vibration-resistant cylindrical air filter structure is designed by adopting a hexagonal stable structure, which greatly enhances the stability and vibration resistance of the filter and filter element, and can perform low-noise operation. Its structural design takes into account the smoothness of the airflow and enhances the large air volume processing capacity; as well as the multi-level filtration structure, improves the filtration efficiency and extends the life of the filter element.

[0072] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
