Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, specifically to a modularly configured cartridge dust collector. Background Technology

[0002] Cartridge dust collectors are dust collectors that use filter cartridges as filtration elements or employ pulse jet cleaning. Based on installation methods, cartridge dust collectors can be categorized into inclined, side-mounted, suspended, and top-mounted types. They are commonly used in various industrial sectors, including coal-fired power plants, steel smelting, cement industry, timber industry, powder recycling, and grain processing. Cartridge dust collectors offer advantages such as high dust removal efficiency, wide adaptability, ease of maintenance, and high filtration accuracy. They capture particulate matter through fine pores and electrostatic attraction, effectively reducing smoke and dust emissions. They are suitable for various industrial environments and dust types. However, existing common cartridge dust collectors require the entire dust collector to be shut down for filter cartridge replacement and cleaning. During the shutdown period, newly generated dust cannot be cleaned. If workers are slow in their loading and unloading, they will be operating in a dust-filled environment, potentially affecting their health. Furthermore, if the entire plant ceases production, it will result in significant economic losses. Utility Model Content

[0019] Reference Figures 1 to 5 As shown, this utility model provides a modular cartridge dust collector, including: a diversion box 1, with an upper guide cylinder 5 and a lower guide cylinder 9 symmetrically connected to the surfaces of the diversion box 1 and the junction box 11, respectively. The two ends of the drive shaft 16 are movably connected to the diversion box 1 and the junction box 11 through sealed bearings. An air pump 12 is fixedly connected to the lower surface of the junction box 11, and a main adjustment plate 13 and a secondary adjustment plate 10 are fixedly connected to the two ends of the drive shaft 16, respectively. Buffer grooves are symmetrically opened on the side of the main adjustment plate 13, and a positioning element 19 is slidably connected to the buffer groove through a limit block 20. A positioning hole 4 is opened on the side of the diversion box 1 corresponding to the position of the positioning element 19. An electromagnet 3 is fixedly connected to the outer side of the diversion box 1 relative to the position of the positioning hole 4. Meanwhile, a filter cartridge 14 is fixedly connected to the inner cavity of the mounting cylinder 7 through a mounting bracket 15. A lower fastening ring 8 is fixedly connected to the lower surface of the mounting cylinder 7, and an upper fastening ring 6 is screwed onto the upper surface of the mounting cylinder 7. The two ends of the mounting cylinder 7 are fixedly connected to the upper guide cylinder 5 and the lower guide cylinder 9 through the upper fastening ring 6 and the lower fastening ring 8, respectively.

[0020] In this embodiment, when the cartridge dust collector needs to perform corresponding dust removal treatment on the surrounding environment, the air pump 12 is turned on. The air pump 12 draws gas from the manifold 11, creating a negative pressure environment inside the manifold 11. Then, the external airflow flows through the diversion box 1 into the corresponding connected upper guide cylinder 5. The airflow in the upper guide cylinder 5 passes through the filter cartridge 14 in the mounting cylinder 7 and the lower guide cylinder 9 in sequence into the manifold 11, thereby realizing the circulation of airflow and enabling the dust collector to perform corresponding dust removal treatment on the surrounding environment. When the filter cartridge 14 in the dust collector needs to be replaced and cleaned, the electromagnet 3 is turned off first. The electromagnet 3 stops adsorbing the positioning member 19. Then, under the action of the squeezed elastic element, the positioning member 19 can automatically move out of the positioning hole 4 and into the buffer groove, successfully releasing the restriction between the diversion box 1 and the main adjusting plate 13. Then, the drive shaft 16 is rotated. The 6 can drive the main adjusting plate 13 and the auxiliary adjusting plate 10, which are fixedly connected, to rotate synchronously and start the electromagnet 3. Then, after the transmission shaft 16 rotates 90 degrees, the new positioning piece 19 can be aligned with the positioning hole 4. Under the magnetic attraction of the electromagnet 3, the new positioning piece 19 squeezes the corresponding elastic element into the positioning hole 4, thereby fixing the diversion box 1 and the main adjusting plate 13. Moreover, the main adjusting plate 13 and the auxiliary adjusting plate 10 can close the airflow channel corresponding to the old filter cylinder 14 and open the airflow channel corresponding to the new filter cylinder 14. By rotating the upper fastening ring 6, the upper fastening ring 6 moves down and resets, thereby fixing the upper guide cylinder 5, the mounting cylinder 7 and the lower guide cylinder 9. The mounting cylinder 7 can be easily removed, and the mounting cylinder 7 and the filter cylinder 14 inside it can be modularly installed, removed and replaced. This allows the dust collector to be cleaned and replaced without stopping the machine, ensuring the health of the surrounding workers.

[0021] In a preferred embodiment, the diversion box 1 has a cylindrical structure, and multiple sets of through openings are opened at equal intervals around the upper end of the arc surface of the diversion box 1, and a filter screen 2 is fixedly connected inside the through openings. The filter screen 2 has a fan-shaped annular structure.

[0022] In this embodiment, as Figure 1 and Figure 2 The filter screen 2 can effectively intercept large debris from the external environment, thereby helping to extend the service life of the filter cartridge 14 and reduce the frequency of filter cartridge 14 replacement by workers.

[0023] In a preferred embodiment, both the main adjusting plate 13 and the auxiliary adjusting plate 10 are circular in shape. The main adjusting plate 13 and the auxiliary adjusting plate 10 are adapted to the dimensions of the inner cavities of the diverter box 1 and the junction box 11, respectively. The lower surface of the main adjusting plate 13 is attached to the bottom of the inner cavity of the diverter box 1, while the upper surface of the auxiliary adjusting plate 10 is attached to the top of the inner cavity of the junction box 11. At the same time, two sets of through holes are symmetrically opened on the surfaces of the main adjusting plate 13 and the auxiliary adjusting plate 10.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The structural design of the main regulating plate 13 and the auxiliary regulating plate 10 can help enhance the sealing of the connection between the main regulating plate 13 and the diversion box 1 and the connection between the auxiliary regulating plate 10 and the junction box 11. At the same time, the through hole design allows the airflow channel connecting the diversion box 1 and the junction box 11 to be easily adjusted, enabling the dust collector to replace the filter cartridge 14 without stopping the machine.

[0025] In a preferred embodiment, four sets of upper guide cylinders 5 are fixedly connected to the lower surface of the diversion box 1. The four sets of upper guide cylinders 5 are all cylindrical in shape, and the lower end of the outer side of the upper guide cylinder 5 is fixedly connected to a limiting ring 17. The limiting ring 17 is an annular structure, and a sealing strip is fixedly connected to the lower surface of the limiting ring 17.

[0026] In this embodiment, as Figure 1 and Figure 4 The setting of the limiting ring 17 can effectively block the movement range of the upper fastening ring 6, while the setting of the sealing strip can help enhance the squeezing effect of the limiting ring 17 on the sealing sleeve 18 during the process of the limiting ring 17 blocking the upper fastening ring 6, thereby enhancing the sealing performance at the connection between the mounting cylinder 7 and the upper guide cylinder 5.

[0027] In a preferred embodiment, four sets of lower guide tubes 9 are fixedly connected to the upper surface of the junction box 11. All four sets of lower guide tubes 9 are cylindrical in shape, and the mounting tube 7 between the lower guide tube 9 and the upper guide tube 5 is cylindrical in shape. At the same time, the dimensions of the upper guide tube 5, the mounting tube 7 and the lower guide tube 9 are all compatible.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The number and position of the upper guide tube 5, the mounting tube 7 and the lower guide tube 9 correspond one-to-one, which ensures that the mounting tube 7 and the filter tube 14 filled inside it can be modularly installed, removed and replaced, thus helping to improve the work efficiency of workers when handling the dust collector.

[0029] In a preferred embodiment, four sets of buffer grooves are equally spaced around the circumference of the main adjustment plate 13. All four sets of buffer grooves are cylindrical in shape, and the limiting block 20 fixedly connected at the opening of the buffer groove is annular in shape. At the same time, the buffer grooves and the two sets of through holes on the surface of the main adjustment plate 13 are staggered.

[0030] In this embodiment, as Figure 2 , Figure 3 and Figure 5The staggered angle setting of the buffer groove and the through hole ensures that when the through hole of the main adjustment plate 13 is connected to the inner cavity of the guide tube 5, the buffer groove can also be aligned with the positioning hole 4, thereby helping to reduce the difficulty of the positioning component 19 being embedded in the positioning hole 4.

[0031] In a preferred embodiment, the axial section of the positioning member 19 is T-shaped, the tail end of the positioning member 19 located in the buffer groove is circular, the size of the tail end of the positioning member 19 is adapted to the size of the buffer groove, and the tail end of the positioning member 19 is sleeved with an elastic element, while the size of the head end of the positioning member 19 is adapted to the inner cavity of the limiting block 20, and the upper end of the positioning member 19 is frustum-shaped.

[0032] In this embodiment, as Figure 2 , Figure 3 and Figure 5 The structural design of the positioning element 19, in conjunction with the elastic element and the limiting block 20, enables the positioning element 19 to have a corresponding automatic reset effect within the buffer groove, and also effectively prevents the positioning element 19 from accidentally detaching from the buffer groove.

[0033] In a preferred embodiment, both the lower fastening ring 8 and the upper fastening ring 6 are annular structures, and the axial sections of both the lower fastening ring 8 and the upper fastening ring 6 are L-shaped structures. The inner cavity of the upper fastening ring 6 is fixedly connected to the sealing sleeve 18, which has an L-shaped axial section. Meanwhile, the inner cavity of the lower fastening ring 8 is fixedly connected to the sealing gasket.

[0034] In this embodiment, as Figure 1 and Figure 4 The upper fastening ring 6 is screwed to the upper end of the outer side of the mounting cylinder 7, which allows the upper fastening ring 6 to move along the axial direction of the mounting cylinder 7, thereby enabling convenient loading and unloading between the upper guide cylinder 5, the mounting cylinder 7 and the lower guide cylinder 9. Moreover, the sealing sleeve 18 and the sealing gasket can further enhance the sealing performance at the connection between the three.
