Description

Technical Field

[0001] This invention relates to the field of filter technology, specifically to an activated carbon filter based on a nitrogen generator unit. Background Technology

[0002] Nitrogen gas, as an inert gas, possesses chemical stability and is not easily reacted with other substances. It is widely used in various industries such as food packaging, electronic protection, chemical inerting, and pharmaceutical nitrogen filling. Its purity and gas production stability directly determine the quality of downstream products and the safety of production processes. Nitrogen generators are the core equipment for producing nitrogen. Currently, the mainstream nitrogen production technologies mainly include membrane separation nitrogen generation and pressure swing adsorption (PSA) nitrogen generation. Both use compressed air as the sole raw material and achieve nitrogen-oxygen separation through different separation principles. Membrane separation nitrogen generation relies on the selective permeation of hollow fiber polymer membranes, while pressure swing adsorption nitrogen generation uses carbon molecular sieves as adsorbents, utilizing the difference in adsorption amounts of oxygen and nitrogen molecules on the adsorbent to complete the separation process. However, existing devices still have some shortcomings. When the air to be treated enters the device, the airflow tends to form irregular turbulence, making it difficult to distribute evenly and penetrate the activated carbon adsorption layer. This results in uneven activated carbon adsorption efficiency, with some areas where the activated carbon does not have sufficient contact with the air, making it difficult to effectively utilize its adsorption performance and causing material waste. In other areas, the airflow is too concentrated, leading to excessive adsorption load and reaching adsorption saturation in a short time. This significantly reduces the overall adsorption capacity and service life. Furthermore, there are gaps between the activated carbon packing structure and the inner wall of the device, making it difficult to form a tight fit. Some air can easily form short-circuit airflows along these gaps, passing directly without effective adsorption and purification by the activated carbon. This not only weakens the removal effect of oxygen and impurities but also significantly reduces the nitrogen separation and purification efficiency and the purity of the nitrogen product, adversely affecting the overall performance and operational stability of the nitrogen generator. Summary of the Invention

[0003] The purpose of this invention is to provide an activated carbon filter based on a nitrogen generator unit to solve the problems mentioned in the background. The technical solution of this invention addresses the technical problem that existing solutions make it difficult for air to concentrate, so that air passes through the activated carbon evenly and smoothly, thereby improving adsorption utilization and filtration effect. This invention provides a solution that is significantly different from existing technologies.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an activated carbon filter based on a nitrogen generator unit, comprising a tank body, a dual-shaft motor disposed within the tank body, a swirling structure at one end of the dual-shaft motor, and a compaction structure at the other end; an upper cover at one end of the tank body, and a lower cover at the other end; an air inlet on the upper cover, an air outlet on the lower cover, and a feed inlet on the tank body; the swirling structure includes a diffuser disposed within the tank body, a guide cone rotatably disposed on the diffuser, an inner sleeve disposed on the guide cone, and a porous flow plate movably disposed on the inner sleeve; the compaction structure includes a support plate fixed within the tank body, a porous compaction plate displaceably disposed on the support plate, and a cleaning component disposed on the support plate, one end of the cleaning component abutting against the porous compaction plate, and the other end abutting against the inner wall of the tank body.

[0005] Preferably, the inner sleeve is provided with a groove, the inner sleeve is provided with a sleeve, the sleeve is provided with a spiral groove, the sleeve is fixed to the inner wall of the tank, the moving rod is provided with a limiting post, the limiting post passes through the groove and extends into the spiral groove, and the moving rod is connected to the porous flow plate.

[0006] Preferably, the porous flow plate has inclined holes.

[0007] Preferably, the groove is Z-shaped, and the groove overlaps with the spiral groove portion.

[0008] Preferably, a connecting rod is rotatably provided on the support plate, a lead screw is provided on the connecting rod, a lead screw nut is provided on the lead screw, and the lead screw nut is connected to the multi-hole pressure plate.

[0009] Preferably, the connecting rod is provided with a driving gear, the support plate is provided with a slot, a driven gear is movably disposed in the slot, and the driving gear and the driven gear are meshed and connected.

[0010] Preferably, the cleaning assembly includes an external gear disposed on the support plate, the external gear meshing with the driven gear, an internal gear disposed inside the tank, the internal gear meshing with the external gear, and a cleaning plate disposed on the internal gear.

[0011] Preferably, the cleaning plate is L-shaped, with one side of the cleaning plate fitting against the inner wall of the tank and the other side fitting against the porous pressure plate.

[0012] Preferably, one end of the output shaft of the dual-axis motor is connected to the connecting rod, and the other end of the output shaft is connected to the guide cone.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes a guide cone, inner sleeve, sleeve, moving rod, and porous flow plate in cooperation. The guide cone rotates, causing the inner sleeve to rotate as well. The inner sleeve has a groove, and the moving rod has a limiting post. Since the limiting post is located within the groove, and the inner sleeve is fixed with a spiral groove, and the limiting post on the moving rod is located within the spiral groove, the spiral groove partially overlaps with the groove. This causes the porous flow plate to shift during the rotation of the inner sleeve, preventing air from concentrating and ensuring that the air passes through the activated carbon evenly and smoothly. This invention can simultaneously compact and clean activated carbon. A dual-shaft motor drives a connecting rod to rotate clockwise. Since the connecting rod is connected to a lead screw, this rotation causes the lead screw to rotate. During rotation, the lead screw drives a porous pressure plate to compact the activated carbon, ensuring it adheres firmly to the inner wall of the container and preventing gaps. Simultaneously, the rotation of the connecting rod drives a drive gear, which in turn drives a driven gear. Because the rotation is clockwise and the driven gear is movable, the drive gear moves the driven gear away from the external gear, preventing engagement. This ensures a uniform airflow distribution and forces the airflow through the activated carbon adsorption layer, preventing airflow deviation, short circuits, and localized issues. The high flow rate improves adsorption utilization and filtration effect. During the compaction process, activated carbon shifts from the holes in the porous plate to the plate itself. When cleaning the activated carbon on the porous plate, rotating the connecting rod counterclockwise causes the lead screw to reverse, moving the porous plate away from the activated carbon. Simultaneously, the rotating connecting rod drives the drive gear, which in turn drives the driven gear. Because the rotation is counterclockwise and the driven gear is movable, the drive gear moves the driven gear closer to the outer gear, meshing with it. The outer gear meshes with the inner gear, causing the cleaning plate on the inner gear to rotate, thus cleaning the activated carbon on the porous plate and preventing accumulation.

[0017] Please see Figures 1-9 The present invention provides a technical solution: an activated carbon filter based on a nitrogen generator unit, comprising a tank 1, wherein a dual-shaft motor 4 is provided inside the tank 1, one end of the dual-shaft motor 4 is provided with a swirl structure 5 and the other end is provided with a compaction structure 6, one end of the tank 1 is provided with an upper cover 2 and the other end is provided with a lower cover 7, the upper cover 2 is provided with an air inlet 3, the lower cover 7 is provided with an air outlet 9, and the tank 1 is provided with a feed inlet 8; The swirl structure 5 includes a diffuser 502 disposed on the tank body 1, a guide cone 503 rotatably disposed on the diffuser 502, an inner sleeve 507 disposed on the guide cone 503, and a perforated flow plate 501 movably disposed on the inner sleeve 507. The compaction structure 6 includes a support plate 603 fixed inside the tank 1. A porous compaction plate 602 is displaceably disposed on the support plate 603. A cleaning component 608 is disposed on the support plate 603. One end of the cleaning component 608 abuts against the porous compaction plate 602, and the other end abuts against the inner wall of the tank 1.

[0018] In one embodiment of the present invention, a groove 508 is provided on the inner sleeve 507, a sleeve 505 is provided on the inner sleeve 507, a spiral groove 506 is provided on the sleeve 505, the sleeve 505 is fixed on the inner wall of the tank body 1, a limiting post 509 is provided on the moving rod 504, the limiting post 509 passes through at least the groove 508 and extends into the spiral groove 506, and the moving rod 504 is connected to the porous flow plate 501; The porous flow plate 501 has inclined holes. The groove 508 is Z-shaped, and the groove 508 partially overlaps with the spiral groove 506; The dual-axis motor 4 is started, which drives the vortex structure 5 to operate. One end of the dual-axis motor 4 drives the guide cone 503 to rotate. During the rotation of the guide cone 503, the inner sleeve 507 is also rotated. Since the inner sleeve 507 is provided with a groove 508 and a moving rod 504 is provided inside the inner sleeve 507, and a limiting post 509 is provided on the moving rod 504, and since the limiting post 509 is located inside the groove 508, and since the inner sleeve 507 is provided with a sleeve 505, which is fixed and has a spiral groove 506, and since the limiting post 509 on the moving rod 504 is located inside the spiral groove 506, and since the spiral groove 506 partially overlaps with the groove 508, the inner sleeve 507 drives the porous flow plate 501 to move during the rotation, making it difficult for air to concentrate and allowing air to pass through the activated carbon evenly and smoothly.

[0019] In one embodiment of the present invention, a connecting rod 604 is rotatably provided on the support plate 603, a lead screw 601 is provided on the connecting rod 604, a lead screw nut is provided on the lead screw 601, and the lead screw nut is connected to the porous pressure plate 602. The connecting rod 604 is provided with a drive gear 605, the support plate 603 is provided with a slot 607, the slot 607 is movably provided with a driven gear 606, and the drive gear 605 and the driven gear 606 are meshed and connected. During the compression of activated carbon, the connecting rod 604 is rotated clockwise by the dual-shaft motor 4. Since the connecting rod 604 is connected to the lead screw 601, it drives the lead screw 601 to rotate. During the rotation, the lead screw 601 drives the porous pressure plate 602 to compact the activated carbon, making the activated carbon adhere to the inner wall of the tank 1, so that the activated carbon is less likely to have gaps with the inner wall of the tank 1. At this time, the connecting rod 604 drives the drive gear 605 to rotate, which in turn drives the driven gear 606 to rotate. Because the rotation is clockwise and the driven gear 606 is movable, the drive gear 605 drives the driven gear 606 away from the external gear 6081 and does not mesh with the external gear 6081. This makes the airflow evenly distributed and forced to pass through the activated carbon adsorption layer, avoiding airflow deviation, short circuits, and excessively high local flow rates, thereby improving the adsorption utilization rate and filtration effect.

[0020] In one embodiment of the present invention, the cleaning component 608 includes an external gear 6081 disposed on the support plate 603, the external gear 6081 being meshed with the driven gear 606, an internal gear 6082 disposed inside the tank body 1, the internal gear 6082 being meshed with the external gear 6081, and a cleaning plate 6083 disposed on the internal gear 6082; The cleaning plate 6083 is L-shaped, with one side of the cleaning plate 6083 fitting against the inner wall of the tank 1 and the other side fitting against the porous pressure plate 602; Rotating the connecting rod 604 counterclockwise causes the lead screw 601 to reverse, moving the porous pressure plate 602 away from the activated carbon. Simultaneously, the rotation of the connecting rod 604 drives the drive gear 605 to rotate, which in turn drives the driven gear 606. Because the rotation is counterclockwise and the driven gear 606 is movable, the drive gear 605 moves the driven gear 606 closer to the external gear 6081, meshing with it. The external gear 6081 meshes with the internal gear 6082, thus rotating the cleaning plate 6083 on the internal gear 6082. This cleans the activated carbon on the porous pressure plate 602, preventing its accumulation.

[0021] Working principle: First, gas enters the tank 1 through the air inlet 3. Then, activated carbon is moved into the tank 1 through the feed inlet 8. Next, the dual-shaft motor 4 is started, which drives the vortex structure 5 to operate. This causes one end of the dual-shaft motor 4 to rotate the guide cone 503. During the rotation of the guide cone 503, the inner sleeve 507 rotates. Since the inner sleeve 507 is provided with a groove 508, and a moving rod 504 is provided inside the inner sleeve 507, the moving rod 504 is provided with a limit post 509. Furthermore, since the limiting post 509 is inside the tank 508, and the inner cylinder 507 is provided with a sleeve 505, and since the sleeve 505 is fixed, and the sleeve 505 is provided with a spiral groove 506, and the limiting post 509 on the moving rod 504 is located inside the spiral groove 506, since the spiral groove 506 partially overlaps with the tank 508, the inner sleeve 507 drives the porous flow plate 501 to move during rotation, making it difficult for air to concentrate, and making the air pass through the activated carbon evenly and smoothly. When compressing activated carbon, the connecting rod 604 is driven to rotate clockwise by the dual-shaft motor 4. Since the connecting rod 604 is connected to the lead screw 601, it drives the lead screw 601 to rotate. During the rotation, the lead screw 601 drives the porous pressure plate 602 to compact the activated carbon, making the activated carbon adhere to the inner wall of the tank 1, so that the activated carbon is less likely to have gaps with the inner wall of the tank 1. At this time, the connecting rod 604 drives the drive gear 605 to rotate, which in turn drives the driven gear 606 to rotate. Because the rotation is clockwise and the driven gear 606 is movable, the drive gear 605 drives the driven gear 606 away from the external gear 6081 and does not mesh with the external gear 6081, so that the porous pressure plate 602 compacts the activated carbon. In addition, a filter screen is set at the bottom of the lead screw 601 to prevent carbon ash from entering the interior, thereby improving the adsorption utilization rate and filtration effect. During the compaction process, activated carbon is displaced from the holes in the porous plate 602 onto the plate. When cleaning the activated carbon on the porous plate 602, the connecting rod 604 is rotated counterclockwise. The connecting rod 604 drives the lead screw 601 to reverse, causing the porous plate 602 to move away from the activated carbon. At the same time, the connecting rod 604 drives the drive gear 605 to rotate, which in turn drives the driven gear 606 to rotate. Because the rotation is counterclockwise and the driven gear 606 is movable, the drive gear 605 drives the driven gear 606 to approach the external gear 6081 and mesh with it. The external gear 6081 is meshed with the internal gear 6082, which in turn drives the cleaning plate 6083 on the internal gear 6082 to rotate, thereby cleaning the activated carbon on the porous plate 602 and preventing accumulation.
