Description

Technical Field

[0001] This utility model relates to the field of dust filtration technology, and in particular to a novel dust filter element. Background Technology

[0002] In modern industry and transportation, critical equipment such as engines and compressors have extremely high requirements for intake air quality. As a core filtration component, the performance of the filter element directly affects the operating efficiency and lifespan of the equipment. Traditional filter elements mainly intercept large particulate pollutants. However, with the improvement of environmental standards and the development of equipment precision, the demand for filtering fine particulate matter (such as PM2.5) and harmful gases (such as sulfides and nitrogen oxides) in the air is becoming increasingly prominent. Especially in environments with high dust concentration and harsh operating conditions, filter elements with a single filtration mechanism are difficult to meet the requirements for long-term stable purification. Therefore, developing a new type of dust filter element with multiple filtration, high-efficiency adsorption and easy maintenance has become an important breakthrough direction for improving filter performance, which is of great significance for extending the service life of equipment and reducing maintenance costs.

[0003] Currently, most filter elements used in filters are based on single-layer filtration structures, such as pleated fiber filter paper, sintered metal mesh, or foam cotton. They rely on the principle of physical barrier to achieve particulate matter separation. Fiber filter paper increases the filtration area through dense pleats and uses the gaps between fibers to trap dust. Sintered metal mesh achieves mechanical sieving through the microporous structure formed by high-temperature sintering.

[0004] A significant drawback of existing filter cartridges is that a single filtration layer cannot effectively remove both fine particles and odor pollutants from the air simultaneously. For example, fiber filter paper has limited interception efficiency for ultrafine particles smaller than PM2.5, while activated carbon layers, although capable of adsorbing odors, are easily covered by dust and become ineffective, resulting in incomplete overall purification of the filter cartridge. Therefore, a filter cartridge structure that integrates multi-stage filtration and chemical adsorption functions is needed to solve the problem of insufficient purification by a single filtration layer. To address this, a novel dust filter cartridge is proposed to solve the aforementioned problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a novel dust filter element, which aims to improve the problem that the single filter layer in the existing technology is difficult to fully filter out small particles and odors in the air.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel dust filter element, comprising a filter cover, a fixing ring fixedly connected to the outer wall of the filter cover, a sealing plate fixedly connected to one side of the filter cover, a fixing frame fixedly connected to the other side of the filter cover, an adsorption frame slidably connected inside the fixing frame, and an adsorption component disposed inside the adsorption frame.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-5 The present invention provides an embodiment of a novel dust filter element, comprising a filter cover 1 for preliminary dust filtration of air, a fixing ring 2 fixedly connected to its outer wall to enhance the structural stability of the filter cover 1 and facilitate installation and fixing, a sealing plate 3 fixedly connected to one side of the filter cover 1 to ensure the airtightness of the filtration system and prevent leakage of unfiltered air, a fixing frame 4 fixedly connected to the other side of the filter cover 1 to accommodate the adsorption component and guide the airflow, an adsorption frame 7 slidably connected inside the fixing frame 4 to facilitate replacement and maintenance, and an adsorption component disposed inside the adsorption frame 7.

[0034] The adsorption assembly includes an adsorption mesh layer 6, which is used for secondary adsorption and purification of the air after preliminary filtration. It is externally fixedly connected to the inner wall of the adsorption frame 7. A pull frame 5 is fixedly connected to the top of the adsorption frame 7, which is used to facilitate the operator to pull the adsorption frame 7 for replacement. A hollow column 8 is fixedly connected inside the fixed frame 4. The hollow column 8 is used to support the disassembly assembly and provide structural stability. A disassembly assembly is set inside the hollow column 8, which is used to assist in the quick disassembly and assembly of the adsorption frame 7. A pulling column 17 is slidably connected inside the sealing plate 3. The pulling column 17 is used to transmit operating force to drive the dust removal assembly to work. A pull handle 20 is fixedly connected to one end of the pulling column 17. The pull handle 20 is used for manual operation to pull or rotate the pulling column 17. A dust removal assembly is set at the other end of the pulling column 17, which is used to remove dust attached to the inner wall of the filter cover 1 to prevent clogging.

[0035] Reference Figures 1-5 The disassembly assembly includes a sliding column 10 and a locking ball 9. The sliding column 10 moves linearly within the hollow column 8 to control the engagement state of the locking ball 9. The side wall of the locking ball 9 is fixedly connected to one end of the sliding column 10. The locking ball 9 forms a detachable snap-fit ​​connection with the adsorption frame 7. The locking ball 9 is slidably connected inside the hollow column 8. The engagement of the locking ball 9 with the adsorption frame 7 enables the rapid fixing and release of the adsorption frame 7. A limiting block 12 is fixedly connected to the outer wall of the sliding column 10 to limit the movement range of the sliding column 10 and prevent excessive displacement. A spring 11 is sleeved on the outer wall of the sliding column 10. The spring 11 provides the automatic reset elastic force for the locking ball 9. One end of the spring 11 is fixedly connected to the side wall of the locking ball 9, and the other end of the spring 11 is fixedly connected to the inner wall of the hollow column 8 to form an elastic support structure.

[0036] The dust removal assembly includes a connecting rod 13 and a scraper ring 14. The connecting rod 13 transmits the movement of the pulling column 17 to the scraper ring 14. The connecting rod 13 is fixedly connected inside the pulling column 17. The scraper ring 14 scrapes off the dust adhering to the inner wall of the filter cover 1. The inner wall of the scraper ring 14 is fixedly connected to both ends of the connecting rod 13 to form a linkage structure. A fixing plate 18 is provided on the outer wall of the pulling column 17. The fixing plate 18 supports the rotational movement of the pulling column 17. The pulling column 17 is rotatably connected inside the fixing plate 18 to achieve rotational movement. The rotating function is provided by a spring 19 on the outer wall of the pull column 17. The spring 19 provides the automatic reset force of the pull column 17. One end of the spring 19 is fixedly connected to the inner wall of the fixed plate 18, and the other end of the spring 19 is fixedly connected to the inner wall of the sealing plate 3 to form an elastic connection. A fixed column 15 is fixedly connected inside the scraper ring 14. The fixed column 15 is used to install the cleaning brush 16. The cleaning brush 16 is rotatably connected to the outer wall of the fixed column 15. The cleaning brush 16 is used to rotate and clean the dust on the inner wall of the filter cover 1.

[0037] Working Principle: When more thorough filtration of airborne dust is required, the adsorption mesh layer 6, installed inside the adsorption frame 7 which slides within the fixed frame 4, adsorbs the dust. The adsorption mesh layer 6 is detachable from the fixed frame 4. To replace it, pull the pull frame 5 upwards, causing the adsorption frame 7 to slide upwards within the fixed frame 4. As the adsorption frame 7 slides upwards, its inner wall compresses the retaining ball 9, separating it from the frame. Under this pressure, the retaining ball 9 slides into the hollow column 8, simultaneously compressing the spring 11 via the sliding column 10. This unlocks the assembly, allowing the adsorption mesh layer 6 to be removed from the fixed frame 4 for replacement. Replacing the adsorption mesh layer 6 further filters airborne dust and odors. When the filter cover 1 is used for an extended period... After use, dust will adhere to the inner wall. At this time, the inner wall of the filter cover 1 needs to be treated so that the filter element can continue to be used. At this time, by pulling the handle 20, the pulling column 17 is moved to slide inside the sealing plate 3. At the same time, the pulling column 17 moves the connecting rod 13 and the scraper ring 14 to slide inside the filter cover 1. Meanwhile, the edge of the scraper ring 14 contacts the inner wall of the filter cover 1. The scraper ring 14 scrapes the dust attached to the inner wall of the filter cover 1. At the same time, when the pulling column 17 moves the connecting rod 13, it will drive the fixed column 15 to compress the spring 19. Also, the pulling column 17 can rotate inside the fixed plate 18, which will drive the scraper ring 14 and the fixed column 15 to rotate inside the filter cover 1. When the scraper ring 14 rotates, it will drive the fixed column 15 and the cleaning brush 16 to rotate inside the filter cover 1, thereby achieving the purpose of deep dust removal inside the filter cover 1.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
