Description

Technical Field

[0001] This utility model belongs to the field of dust collector technology, and in particular relates to an industrial dust collector with a fast-cleaning filter cartridge structure. Background Technology

[0002] An industrial dust collector is an environmentally friendly device used in industrial production processes to efficiently collect, filter, and remove dust and particulate matter from the air. Its core function is to separate suspended solid pollutants from the airflow through filtration and purification, thereby purifying the working environment and achieving centralized dust treatment. The system typically consists of a sealed housing, filtration device, power fan, dust removal mechanism, and dust collection container. During operation, dust-laden gas enters the equipment through the inlet pipe under negative pressure. As it passes through filter media such as filter cartridges, the dust is trapped on the surface of the filter material, and the purified clean air is discharged through the outlet pipe.

[0003] In the actual operation of industrial dust collectors, as dust-laden airflow continuously passes through the filter cartridges for filtration, fine dust particles gradually form a dense dust layer on the surface of the filter media. While this continuously accumulating dust layer improves the initial filtration efficiency to some extent, it leads to a significant decrease in the air permeability of the filter cartridges and a sharp increase in airflow resistance over time. This not only greatly increases the energy consumption of the fan but also seriously affects the overall dust removal performance of the system.

[0004] In traditional reverse-jet cleaning, when high-pressure gas is injected from inside the filter cartridge, a significant pressure gradient is created due to the gas flow characteristics within the narrow cartridge. The upper region, being closer to the gas source, experiences stronger cleaning power. However, as the airflow descends, its kinetic energy gradually diminishes, resulting in insufficient reverse-jet strength in the lower region of the filter cartridge, making it difficult to effectively remove the dust accumulation layer in that area. This uneven cleaning effect causes dust to continuously accumulate in the lower part of the filter cartridge, eventually leading to caking and further exacerbating the uneven airflow distribution.

[0005] More notably, when dust removal is incomplete, operators often compensate by increasing compressed air pressure or extending the blowing time. This practice further amplifies the damage to the filter media, creating a vicious cycle of "insufficient dust removal - increased force - filter media damage." Physical damage to the filter media not only reduces filtration accuracy, allowing some fine dust to penetrate the filter layer, but also shortens the lifespan of the filter cartridge and increases equipment maintenance costs. Furthermore, the dust layer that is not completely removed gradually hardens, forming dense clumps that are difficult to peel off. These clumps alter the pore structure of the filter media surface, making subsequent dust removal operations more difficult and ultimately necessitating deep cleaning through manual intervention, severely impacting production continuity.

[0036] Please see Figures 1 to 8 The embodiments provided by this utility model are as follows:

[0037] Example: An industrial dust collector with a fast-cleaning filter cartridge structure, comprising:

[0038] The housing 3 has a groove 9 inside, a fixing plate 10 is fixed inside the groove 9, and a mounting ring 21 is rotatably connected inside the fixing plate 10. The lower end of the mounting ring 21 is fixed to the filter cartridge body 13, and the upper end of the mounting ring 21 is fixed to the gear 12. The housing 3 is rotatably connected to the rotating tube 15, and the lower end of the rotating tube 15 is fixed to the gear 4 24, which meshes with the gear 12. The upper end of the rotating tube 15 is fixed to the gear 2 17, and the upper end of the housing 3 is fixed to the bracket 18. The bracket 18 is rotatably connected to the gear 3 19, which meshes with the gear 2 17.

[0039] The inner sleeve of the rotating pipe 15 is connected to the air guide pipe 5, the nozzle 20 is installed on the outer wall of the air guide pipe 5, and the upper end of the air guide pipe 5 is connected to the flexible hose 6.

[0040] The dust removal space is formed by the groove 9 inside the housing 3, and the fixing plate 10 serves as the core support structure to rotatably fix the mounting ring 21 within the groove 9. The mounting ring 21 adopts an upper and lower linkage design: its lower end is fixed to the filter cartridge body 13 to achieve dust filtration, and its upper end is connected to the gear 24 at the lower end of the rotating tube 15 via gear 12 to form a meshing transmission. When the rotating tube 15 rotates, gear 12 is driven to rotate via gear 24, thereby causing the entire filter cartridge body 13 to rotate circumferentially. At the same time, the upper end of the rotating tube 15 is connected to gear 19 on the bracket 18 via gear 27 to form a two-stage transmission system to ensure stable power transmission. The specially designed rotating pipe 15 is internally connected to the air guide pipe 5, and the nozzles 20 arranged on the outer wall of the air guide pipe 5, together with the external air source connected by the hose 6 (because the hose 6 is connected to an external air source, such as the air source delivered by an air compressor, the air guide pipe 5 remains relatively stationary when the rotating pipe 15 rotates. Of course, a rigid support component can also be connected to the upper end of the air guide pipe 5 to keep it fixed), forming a jet airflow to clean the rotating filter cartridge body 13 360° without dead angles, which significantly improves the uniformity and efficiency of cleaning.

[0041] A second circular hole 22 is opened at the upper end of the fixed plate 10, and a second bearing 23 is installed in the second circular hole 22. The upper end of the mounting ring 21 passes through the second bearing 23 and is rotatably connected. A first circular hole 14 is opened at the upper end of the housing 3, and a first bearing 16 is installed in the first circular hole 14. The upper end of the rotating tube 15 passes through the first bearing 16 and is rotatably connected.

[0042] The fixing plate 10 provides rotational support for the mounting ring 21 through the bearing 23 installed in the second circular hole 22, ensuring the stability of the filter cartridge body 13 during rotation. A bearing 16 is installed in the corresponding circular hole 14 at the upper end of the housing 3, allowing the rotating tube 15 to remain axially fixed while rotating freely as it passes through the bearing 16. This double-bearing support structure makes the meshing transmission of gear 12 and gear 4 24 smoother and more reliable.

[0043] The upper end of the bracket 18 is fixed with the motor 11, and the drive end of the motor 11 is equipped with gear 3 19, which is horizontally aligned with the center of gear 2 17.

[0044] The motor 11 mounted on the bracket 18 directly drives the rotation of gear 3 19. The horizontal center alignment design ensures uniform pressure distribution on the meshing surfaces of gear 3 19 and gear 2 17. This layout avoids the axial force generated by gear transmission and allows the driving torque of the motor 11 to be efficiently transmitted to the rotating tube 15, ultimately converting it into the rotational kinetic energy of the filter cartridge body 13. The external mounting of the motor 11 facilitates maintenance and repair while reducing the impact of vibration on the airflow within the housing 3.

[0045] Gear 12 and Gear 424 are on the same horizontal plane.

[0046] By placing gear 12 and gear 24 on the same horizontal plane, a standard parallel shaft gear transmission system is formed. This layout ensures that the contact line of the meshing gears is always parallel to the axis, eliminating the possibility of axial movement and significantly reducing gear transmission noise. When gear 24 rotates under the drive of the rotating tube 15, it maintains a constant meshing depth with gear 12, ensuring stable rotational speed of the filter cartridge body 13 and avoiding vibration or jamming caused by misalignment.

[0047] The upper end of the rotating pipe 15 has a pipe hole 25, and the lower end of the air guide pipe 5 passes through the pipe hole 25 and the fixing plate 10 and extends into the box groove 9. The air guide pipe 5 is rotatably connected to the pipe hole 25, and the air guide pipe 5 can be fixedly connected to the fixing plate 10 (when there is no external support component at the outer end of the air guide pipe 5).

[0048] The pipe hole 25 at the upper end of the rotating pipe 15 serves as a through channel for the air guide pipe 5, allowing the air guide pipe 5 to stably pass through the interior of the rotating pipe 15 and extend into the groove 9 below the fixed plate 10. This structural design ensures that the air guide pipe 5 remains relatively stationary when the rotating pipe 15 rotates, avoiding problems such as air pipe entanglement or twisting caused by rotation. At the same time, the fixed end of the air guide pipe 5 extends into the groove 9, allowing its nozzle 20 to be precisely aligned with the inner wall of the filter cartridge body 13, improving the accuracy and efficiency of dust removal.

[0049] A valve is installed at the upper end of the outer wall of the air duct 5.

[0050] This valve design not only improves the system's controllability but also cuts off the airflow during non-dust cleaning stages, avoiding the waste of compressed air and reducing energy consumption.

[0051] An air outlet pipe 4 is installed at one end of the housing 3, and a valve 2 is installed at the upper end of the air outlet pipe 4. An air inlet pipe 7 is installed at the other end of the housing 3, and a valve 3 is installed at the upper end of the air inlet pipe 7.

[0052] The exhaust pipe 4 installed at one end of the housing 3 is used to discharge filtered clean air, while the intake pipe 7 at the other end of the housing 3 is responsible for introducing dust-laden gas.

[0053] The dust collection box 2 is fixed at the lower end of the box 3, and the dust collection trough 8 is opened at the upper end of the dust collection box 2.

[0054] The dust collection box 2 fixed at the lower end of the box 3 is used to collect the dust that falls off during the dust removal process, and the dust collection trough 8 opened at the upper end serves as a temporary storage space for the dust.

[0055] The dust collection trough 8 of the dust collection box 2 is connected to the box trough 9 of the box body 3.

[0056] The dust collection trough 8 of the dust collection box 2 is directly connected to the box groove 9 of the box body 3, so that the dust falling off during the cleaning process of the filter cartridge body 13 can quickly fall into the dust collection trough 8, avoiding the accumulation of dust around the filter cartridge body 13 and affecting the filtration efficiency. This integrated design optimizes the dust collection path, reduces the impact of airflow disturbance on dust settling, and improves the dust collection effect.

[0057] One end of the box 3 is fixed with support columns 1 at the front and back respectively, and the other end of the box 3 is fixed with support columns 1 at the front and back respectively.

[0058] The housing 3 is fixed to two ends with support columns 1, forming a four-point support structure to ensure the stability of the equipment during operation and reduce the impact of vibration on the transmission system. The symmetrical layout of the support columns 1 ensures that the housing 3 is subjected to uniform force, avoiding deformation or displacement due to long-term operation.

[0059] In this embodiment, when the industrial dust collector needs to be cleaned after long-term operation, the operator first starts the motor 11 fixed to the upper end of the bracket 18. The output shaft of the motor 11 drives the gear 19 to start rotating. Since the gear 19 maintains precise meshing with the gear 17 at the upper end of the rotating tube 15, the power is then transmitted to the rotating tube 15 through the gear 17, allowing it to rotate smoothly under the support of the bearing 16.

[0060] Simultaneously, gear 24 at the lower end of the rotating tube 15 begins to rotate synchronously and meshes with gear 12 at the upper end of the mounting ring 21. This dual gear transmission system ensures that power is transmitted from the motor 11 through gear 3 19, gear 2 17, rotating tube 15, and gear 4 24 to gear 12, driving the entire mounting ring 21 to rotate stably within bearing 23. Since the filter cartridge body 13 is fixedly connected to the lower end of the mounting ring 21, the filter cartridge body 13 also begins to rotate circumferentially.

[0061] While the filter cartridge body 13 rotates, an external compressed air source is connected to the system via a hose 6. The compressed air is delivered via an air guide pipe 5 and ejected from multiple nozzles 20 evenly arranged on the outer wall of the air guide pipe 5. Since the air guide pipe 5 passes through the pipe hole 25 of the rotating pipe 15 and extends into the housing trough 9, the spray direction of the nozzles 20 is always aligned with the outer wall of the rotating filter cartridge body 13. This dynamic cleaning method allows the compressed air to impact the filter material at the optimal angle, thoroughly stripping away the dust layer.

[0062] Throughout the cleaning process, the rotation of the filter cartridge body 13 and the fixed spray of the nozzle 20 form a perfect dynamic-static coordination. The rotating filter cartridge body 13 ensures that its entire outer surface is evenly impacted by the airflow, and the removed dust falls into the dust collection trough 8 of the dust collection box 2 below under the action of gravity, completing the entire cleaning cycle.

[0063] This linked cleaning mechanism has significant advantages over traditional fixed backflushing systems: First, the rotating filter cartridge body 13 makes the dust removal force distribution more uniform, avoiding localized over-cleaning or under-cleaning; second, the dynamic cleaning method greatly improves dust removal efficiency and reduces compressed air consumption. It achieves the effect of facilitating rapid cleaning of the filter cartridge body 13, while allowing the filter cartridge body 13 to rotate as needed, facilitating cleaning of different positions of the filter cartridge body 13, and ensuring complete cleaning.

[0064] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
