Description

Technical Field

[0001] This utility model belongs to the field of air intake filter technology, and specifically relates to a novel air intake filter. Background Technology

[0002] The VPSA oxygen and nitrogen production process uses air as raw material. Oxygen and nitrogen are separated through pressurized adsorption and depressurized desorption of the adsorbent. However, if impurities such as dust, hair, and oil mist in the air are not treated, they will clog the pores of the adsorbent, wear down equipment valves and pipelines, and lead to a decrease in the purity of the product gas and frequent equipment failures. Therefore, the gas must be filtered efficiently. The intake filter is a graded filtration system that uses an outer coarse filter to intercept large particles and an inner fine filter to remove fine particles.

[0003] Existing internal filter plate fixing structures mostly use bolt fastening, which makes installation and disassembly cumbersome and time-consuming. Especially when multiple sets are installed in parallel, the maintenance efficiency is extremely low. Moreover, the installation method that relies on manual calibration during the installation process is prone to filter plate misalignment or tilting, resulting in gaps between the filter plate and the snap-fit ​​components, which seriously affects the filtration effect and equipment operation safety. Its filter material and structural design make it difficult to balance precision and permeability. Currently, the filter plates are prone to clogging, and the porous structure weakens the filtration effect. In addition, it lacks self-cleaning function, resulting in frequent manual disassembly and cleaning and increased maintenance costs. Utility Model Content

[0034] Example 3

[0035] The cleaning assembly includes electric slide rails 13, with sliders 14 slidably connected to the upper part of one side of each of the two electric slide rails 13. The sliders 14 are L-shaped. A collection box 15 is connected between the two sliders 14. The collection box 15 is located on one side of the box body 1. A guide frame 16 is connected to the lower part of one side of the collection box 15. The guide frame 16 is inclined. A rotating rod 17 is connected to the middle of one side of the guide frame 16. One end of the rotating rod 17 extends through to one side of the guide frame 16. A cleaning brush 18 is connected to the middle of the outer wall of the rotating rod 17. One side of the cleaning brush 18 contacts one side of the outer filter plate 4. Gears 19 are connected to both ends of the rotating rod 17. A rack rod 20 is connected to one side of the box body 1 at the corresponding position of the two gears 19. One side of the two gears 19 meshes with one side of the two rack rods 20 respectively. A movable frame 21 is slidably connected to the lower end of the collection box 15. One end of the movable frame 21 extends through to one side of the collection box 15. A removal plate is connected to one side of the collection box 15.

[0036] The guide frame 16 is inclined and has a smooth inner side. The two ends of the rotating rod 17 are connected to the guide frame 16 through bearings. The cleaning brush 18 is made of wear-resistant nylon bristles. The gear 19 meshes with the rack and pinion 20 for transmission. The edge of the moving frame 21 is provided with a sealing strip. The moving frame 21 can be pulled out through the removal plate to facilitate the cleaning of hair and impurities collected inside.

[0037] Working principle: When using the device, atmospheric gas enters the filter from the door 3 on one side of the housing 1. The gas first undergoes preliminary filtration through the outer filter plate 4 installed on the door 3. The outer filter plate 4 can intercept large particulate impurities, hair, dust, etc. in the air. The gas after preliminary filtration passes through the interior of the housing 1 and reaches the inner filter plate 10 on one side of the housing 9. The inner filter plate 10 performs fine filtration on the gas, removing fine particulate impurities. Finally, the purified gas is discharged through the exhaust pipe 2 in the middle of the upper part of the housing 1 and enters the subsequent VPSA oxygen generation, nitrogen generation and other devices.

[0038] The mounting plate 5 in the snap-fit ​​assembly is fixed to the side of the housing 1. The snap-fit ​​block 6 snaps onto the mounting plate 5. The snap-fit ​​blocks 6 at both ends are connected by the snap-fit ​​plate 7 to form a stable frame structure. The moving block 8 passes through the moving port of the housing 9 and fixes the inner filter plate 10 to one side of the housing 9. When the inner filter plate 10 needs to be installed, push the moving block 8 to make the snap-fit ​​plate 7 and the snap-fit ​​block 6 clamp together, thereby fixing the inner filter plate 10 inside the housing 1 and ensuring that the inner filter plate 10 will not loosen during the filtration process. When disassembling, pull the pull plate 12 to move the moving block 8 inside the housing 9, so that the snap-fit ​​plate 7 and the snap-fit ​​block 6 are separated. The buffer spring 11 between the moving blocks 8 provides buffering force during the pulling process to avoid hard collision between the moving block 8 and the housing 9, and at the same time facilitates reset. The pull plate 12 is located in the sliding port of the housing 9, which makes it convenient for the operator to manually control the movement of the moving block 8.

[0039] An opening is provided on the door 3. The outer filter plate 4 is inserted into the inside of the door 3 through the opening. The cross-shaped baffles on the inner wall of the opening contact one side of the outer filter plate 4 to prevent the outer filter plate 4 from falling off during installation. A sealing frame is connected to the door 3 at the position corresponding to the outer filter plate 4. When the sealing frame is closed, the outer filter plate 4 can be snapped into the inside of the opening to form a sealing structure, preventing gas from leaking from the gap between the outer filter plate 4 and the door 3, thus ensuring the filtration effect.

[0040] Electric slide rails 13 are installed on both sides of the housing 1. The slider 14 has an L-shaped structure and can slide up and down on the electric slide rails 13. When the electric slide rails 13 are powered on, they drive the slider 14 to move up and down along the slide rails, thereby driving the collection box 15 and the guide frame 16 connected between the sliders 14 to move synchronously.

[0041] The guide frame 16 is inclined to facilitate the collection of impurities. The rotating rod 17 passes through the guide frame 16, and the cleaning brush 18 on its outer wall contacts one side of the outer filter plate 4. The gears 19 at both ends of the rotating rod 17 mesh with the rack 20 on the side of the housing 1. When the slider 14 drives the guide frame 16 to move upward, the gears 19 roll on the rack 20, thereby driving the rotating rod 17 to rotate, so that the cleaning brush 18 rolls on the surface of the outer filter plate 4 to remove the attached impurities. The impurities brushed off by the cleaning brush 18 fall onto the guide frame 16. Since the guide frame 16 is inclined, the impurities slide down the guide frame 16 into the collection box 15. The movable frame 21 at the lower end of the collection box 15 can be slid out. When there are many impurities in the collection box 15, the movable frame 21 can be pulled out by removing the removal plate to empty the impurities for easy maintenance.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model.
