Description

Technical Field

[0001] This invention relates to the field of air filtration technology, specifically to an air filtration device for use in filter cartridge workshops. Background Technology

[0002] Air filtration equipment used in filter cartridge workshops primarily functions to efficiently filter dust, toxic gases, and particles in the production environment, preventing them from contaminating filter materials such as activated carbon inside the filter cartridges, ensuring product quality, and simultaneously ensuring clean air in the workshop and protecting worker health.

[0003] In existing air filtration technologies for cartridge-based workshops, a combined main-section and segmented filtration layout is commonly used. The main-section filtration equipment is typically strategically placed in a prominent and easily accessible location within the workshop. Its structural design prioritizes ease of maintenance, allowing for quick and regular disassembly and cleaning, making the maintenance process simple and efficient. However, segmented filtration systems are often cleverly concealed within walls. While this design effectively saves space and optimizes airflow distribution, it also presents significant challenges—due to its hidden location and compact structure, disassembly becomes extremely cumbersome, and cleaning becomes significantly more difficult. This difference makes segmented filtration maintenance a pain point in workshop air management, and inadequate cleaning over the long term can affect overall filtration efficiency. Therefore, we propose an innovative air filtration device for cartridge-based workshops. This device, through optimized structural design, enables convenient disassembly and efficient cleaning of the segmented filtration system, effectively solving the problems in existing technologies and ensuring consistently stable and compliant workshop air quality. Summary of the Invention

[0004] One of the technical problems this application aims to solve is that while segmented filtration systems installed inside walls can save space and optimize airflow distribution, their location makes disassembly extremely complicated and significantly increases the difficulty of cleaning.

[0005] To solve the above-mentioned technical problems, this application provides an air filtration device for a filter cartridge workshop, including a top cover, the bottom of which is fixedly connected to a main section assembly; The main section assembly includes a cylinder fixedly connected to the bottom of the top cover, an arc-shaped pad fixedly connected to the outside of the cylinder, a support frame fixedly connected to the inside of the cylinder, a fan wheel rotatably connected inside the support frame, a motor fixedly connected to the outside of the cylinder, the drive end of the motor extending into the cylinder and fixedly connected to a first bevel gear, a second bevel gear meshing with the first bevel gear, the bottom of the second bevel gear fixedly connected to the fan wheel, a main cleaning component provided at the top of the second bevel gear, and a drive component provided outside the main cleaning component; The cylinder body is provided with a segmented assembly, the segmented assembly includes a segmented box disposed outside the cylinder body, and the segmented box is provided with a cleaning component.

[0006] In some embodiments, the main cleaning component includes a drive shaft fixedly connected to the top of the second bevel gear, a limiting ring fixedly connected to the outside of the drive shaft, the limiting ring being rotatably connected to the cylinder, a rotating ring fixedly connected to the top of the drive shaft, a plurality of scrapers fixedly connected between the rotating ring and the limiting ring, and a drive component disposed outside the rotating ring.

[0007] In some embodiments, the driving member includes an arc-shaped plate rotatably connected to the outside of the rotating ring, and a first spring is fixedly connected between the arc-shaped plate and the rotating ring.

[0008] In some embodiments, the cleaning component includes multiple filter plates fixedly connected within the segmented box, with push rods slidably interspersed among the multiple filter plates. One end of each push rod is rotatably connected to a wheel, and the other end of the push rod extends out of the segmented box.

[0009] In some embodiments, a limiting plate is fixedly connected to the outside of the push rod, and a second spring is sleeved on the outside of the push rod between the limiting plate and the filter plate.

[0010] In some embodiments, a first scraper and a second scraper are fixedly sleeved on the outside of the push rod, and the first scraper and the second scraper are disposed between two adjacent filter plates.

[0011] In some embodiments, a plurality of waste boxes are fixedly connected to the bottom of the segmented box, and a pull-out box is slidably connected inside each of the plurality of waste boxes.

[0012] In some embodiments, four arc-shaped pads are provided, which are disposed between the cylinder and the segment box, and the inner end shapes of the arc-shaped pads and the segment box are matched.

[0013] In some embodiments, the rotating ring extends out of the top of the cylinder and is rotatably connected to it, and the central axes of the rotating ring and the top cover are coaxial.

[0014] In some embodiments, the first scraper is disposed on one side of the filter plate, and the second scraper is disposed in the middle position of two adjacent filter plates. Both the first scraper and the second scraper are configured in a U-shape.

[0015] This invention has at least the following beneficial effects: By setting the main section component, the motor drives the first bevel gear to rotate, which in turn drives the second bevel gear to rotate. The second bevel gear then drives the impeller and drive shaft to rotate. The rotation of the impeller can draw the workshop air into the cylinder, and then output it through the top cover to the existing waste gas treatment equipment, and then discharge it outside the building. During this process, the rotation of the drive shaft can synchronously drive the limit ring and the rotating ring to rotate, thereby driving multiple scrapers to remove the residue generated by filtration inside the cylinder. The rotation of the main section assembly will drive the push rod to drive multiple sets of first and second scrapers to scrape and clean inside the section box. During this process, the rotation of the rotating ring and the limit ring will simultaneously drive multiple scrapers to clean the filter waste inside the cylinder, without the need for frequent disassembly. When the fan rotates and draws air from the main section of the workshop, air from the sub-sections is also drawn in. Thus, the main section is the most important area and is subject to centralized filtration, while the sub-sections are secondary areas and can be distributed for multiple stages of filtration, making it suitable for multi-station workshops.

A support frame 23 is fixedly connected inside the cylinder 21, and a wind turbine 24 is rotatably connected inside the support frame 23. Furthermore, by setting up the impeller 24, air in the workshop can be driven into the cylinder 21. At the same time, air at the segmented position can be simultaneously input into the cylinder 21 through the bottom opening of the segmented box 31. The air at the segmented position can be filtered by multiple filter plates 321.

[0020] A motor 25 is fixedly connected to the outside of the cylinder 21. The drive end of the motor 25 extends into the cylinder 21 and is fixedly connected to a first bevel gear 26. A second bevel gear 27 meshes with the first bevel gear 26. The bottom of the second bevel gear 27 is fixedly connected to the impeller 24. A main cleaning component 28 is provided on the top of the second bevel gear 27. A drive component 29 is provided outside the main cleaning component 28. Furthermore, the motor 25 is started, which drives the first bevel gear 26 to rotate, which in turn drives the second bevel gear 27 to rotate. The second bevel gear 27 then drives the impeller 24 and the drive shaft 281 to rotate. The rotation of the impeller 24 can draw air from the workshop into the cylinder 21.

[0021] A segmentation assembly 3 is provided outside the cylinder 21. The segmentation assembly 3 includes a segmentation box 31 provided outside the cylinder 21, and a cleaning component 32 is provided inside the segmentation box 31.

[0022] The main cleaning component 28 includes a drive shaft 281 fixedly connected to the top of the second bevel gear 27, a limit ring 282 fixedly connected to the outside of the drive shaft 281, the limit ring 282 being rotatably connected to the cylinder 21, a rotating ring 283 fixedly connected to the top of the drive shaft 281, a plurality of scraper blades 284 fixedly connected between the rotating ring 283 and the limit ring 282, and a drive component 29 provided outside the rotating ring 283.

Furthermore, by setting the first spring 292, the impact between the arc plate 291 and the rotating wheel 323 can be reduced, thus avoiding the generation of excessive noise.

[0024] The cleaning component 32 includes multiple filter plates 321 fixedly connected inside the segment box 31. Push rods 322 are slidably inserted between the multiple filter plates 321. One end of the push rod 322 is rotatably connected to a wheel 323, and the other end of the push rod 322 extends out of the segment box 31.

[0026] The push rod 322 is externally fixedly sleeved with a first scraper 326 and a second scraper 327, which are arranged between two adjacent filter plates 321.

[0027] Multiple waste boxes 328 are fixedly connected to the bottom of the segment box 31, and each of the multiple waste boxes 328 has a pull-out box 329 slidably connected inside.

[0028] Four curved pads 22 are provided, and the four curved pads 22 are placed between the cylinder 21 and the segment box 31. The inner end shapes of the curved pads 22 and the segment box 31 fit together, thus preventing leakage at the bottom. It should be noted that the top of the segment box 31 is fixedly connected to the building ceiling.

[0029] The rotating ring 283 protrudes from the top of the cylinder 21 and is rotatably connected to it. The central axis of the rotating ring 283 and the top cover 1 are coaxial, which can prevent the offset from occurring.

[0030] The first scraper 326 is located on one side of the filter plate 321, and the second scraper 327 is located in the middle of the two adjacent filter plates 321. Both the first scraper 326 and the second scraper 327 are designed in a U-shape to reduce weight and facilitate air entry for filtration through the filter plate 321. It should be noted that the waste box 328 is open on all four sides, also for the purpose of receiving air. In use, the rotation of the drive shaft 281 can synchronously drive the limit ring 282 and the rotating ring 283 to rotate. The rotation of the rotating ring 283 will drive the arc plate 291 to contact the rotating wheel 323, which in turn drives the push rod 322 to rotate. The push rod 322 will then drive multiple sets of first scrapers 326 and second scrapers 327 to scrape and clean in the segmented box 31. During this process, the rotation of the rotating ring 283 and the limit ring 282 will synchronously drive multiple scraper strips 284 to clean the filter waste in the cylinder 21. Example 2

[0033] Furthermore, the motor 25 drives the first bevel gear 26 to rotate, which in turn drives the second bevel gear 27 to rotate. The second bevel gear 27 then drives the impeller 24 and the drive shaft 281 to rotate. The rotation of the impeller 24 can draw the workshop air into the cylinder 21, and then output it through the top cover 1 to the existing waste gas treatment equipment, and then discharge it outside the building. During this process, the rotation of the drive shaft 281 can synchronously drive the limit ring 282 and the rotating ring 283 to rotate. The rotation of the rotating ring 283 will drive the arc plate 291 to contact the rotating wheel 323, which in turn drives the push rod 322 to rotate. The push rod 322 then drives multiple sets of first scrapers 326 and second scrapers 327 to scrape and clean in the segment box 31. The driving component 29 includes an arc-shaped plate 291 rotatably connected to the outside of the rotating ring 283, and a first spring 292 is fixedly connected between the arc-shaped plate 291 and the rotating ring 283.

Furthermore, the rotation of the main section assembly 2 will drive the push rod 322 to drive multiple sets of first scraper 326 and second scraper 327 to scrape and clean in the section box 31. During this process, the rotation of the rotating ring 283 and the limiting ring 282 will synchronously drive multiple scraper strips 284 to clean the filter waste in the cylinder 21, without the need for frequent disassembly. When the impeller 24 rotates and draws air from the main section of the workshop, the air in the sub-sections is also drawn in. In this way, the main section is the most important area and is centrally filtered, while the sub-sections are secondary areas and can be distributed for multiple workstations in the workshop. Furthermore, by setting up a rotating wheel 323, the rotating wheel 323 can contact the arc-shaped plate 291, and then drive the push rod 322 to move, thereby driving the first scraper 326 and the second scraper 327 to scrape and clean the residue in the segment box 31 within the interval composed of multiple filter plates 321.

[0035] A limiting plate 324 is fixedly connected to the outside of the push rod 322, and a second spring 325 is sleeved on the outside of the push rod 322 between the limiting plate 324 and the filter plate 321. Furthermore, by setting a second spring 325, the push rod 322 can be driven to return to its original position in a timely manner.

[0036] The push rod 322 is externally fixedly sleeved with a first scraper 326 and a second scraper 327, which are arranged between two adjacent filter plates 321.

[0037] Multiple waste boxes 328 are fixedly connected to the bottom of the segment box 31, and each of the multiple waste boxes 328 has a pull-out box 329 slidably connected inside it. Furthermore, by setting up a pull-out box 329, the filter residue and waste scraped off by the first scraper 326 and the second scraper 327 can be stored. During this process, the scraped residue and waste are piled up and are not easily sucked back into the segment box 31.

[0038] Four arc-shaped pads 22 are provided, and the four arc-shaped pads 22 are placed between the cylinder 21 and the segment box 31. The inner end shapes of the arc-shaped pads 22 and the segment box 31 are matched.

[0039] Rotating ring 283 protrudes from the top of cylinder 21 and is rotatably connected to it; the central axis of rotating ring 283 and top cover 1 are coaxial. Furthermore, the central axis of the rotating ring 283 and the top cover 1 are coaxial, which can prevent shaking.

[0040] The first scraper 326 is located on one side of the filter plate 321, and the second scraper 327 is located in the middle of two adjacent filter plates 321. Both the first scraper 326 and the second scraper 327 are designed in a U-shape to reduce weight.

[0041] Working principle: First, the motor 25 is started, which drives the first bevel gear 26 to rotate, which in turn drives the second bevel gear 27 to rotate.

The rotation of the impeller 24 can draw the workshop air into the cylinder 21, and then output it through the top cover 1 to the existing waste gas treatment equipment, and then discharge it outside the building. During this process, the rotation of the drive shaft 281 can synchronously drive the limit ring 282 and the rotating ring 283 to rotate. The rotation of the rotating ring 283 will drive the arc plate 291 to contact the rotating wheel 323, which in turn drives the push rod 322 to rotate.

During this process, the rotation of the rotating ring 283 and the limit ring 282 will synchronously drive multiple scraper strips 284 to clean the filter waste in the cylinder 21.
