Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a bottom-mounted assembled filter cartridge dust collector. Background Art

[0002] A dust collector is a device that separates dust from flue gas. Depending on the dust removal principle, it can be categorized as dry, wet, bag, and electrostatic. Since its introduction, dust collectors have been widely used and improved both domestically and internationally, achieving significant progress in both dust-laden gas purification performance and device structure. Currently used cartridge dust collectors are mostly integrally welded. While significantly smaller than bag filters with the same filter area, they are still subject to environmental space limitations (for example, the size of the access opening). Furthermore, bag filters with large filter areas installed outdoors are prone to bag freezing in winter, causing the dust collection system to malfunction. Collected dust also requires manual removal, increasing labor. Bags have a short service life, typically one year. Bag filters are mostly top-accessible and removable, making bag replacement unsafe and labor-intensive. The pulse backflush system used in bag filters consumes a large amount of compressed air. The air bag and solenoid valve are often externally mounted, resulting in a high level of noise. External solenoid valves are susceptible to environmental impacts such as wind, sun, and impact, resulting in a short service life. Welded cartridge dust collectors are bulky and inconvenient to install and transport, often requiring removal of lifting ports or breaking through walls.

[0003] However, for the above-mentioned existing dust collectors, the dust removal structure is usually fastened with screws or welded during installation, and the structural design of each part of the dust collector is not compact, which will increase labor costs and is inconvenient to clean and replace the dust removal structure.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] Reference Figures 1 to 7 The utility model provides a bottom-mounted assembled filter cartridge dust collector, which includes a dust removal box 1, a dust removal component 2, an ash hopper 3, a main fan 4 and a dust cleaning component 5.

[0043] The side wall of the dust removal box 1 is provided with an air outlet 11 and a dust removal space 12 for dust removal is formed inside.

[0044] The dust removal assembly 2 includes a perforated plate 21, a pressing assembly 22 and a filter cartridge 23. The perforated plate 21 is provided with a plurality of blowing holes 211 and is arranged in the dust removal space 12. The pressing assembly 22 is arranged on the perforated plate 21 for fixing the filter cartridge 23 to the perforated plate 21 so that the upper opening of the filter cartridge 23 is sealed and connected to the blowing holes 211 in a one-to-one correspondence. A purification space is formed inside the filter cartridge 23 for communicating with the air outlet 11.

[0045] The ash hopper 3 is provided at the bottom of the dust removal box 1 and communicates with the dust removal space 12 for recovering dust falling into the dust removal space 12 . An air inlet 31 for introducing dust-laden gas is provided on the side wall of the ash hopper 3 .

[0046] The main fan 4 is disposed outside the dust removal box 1 and communicates with the air outlet 11 .

[0047] The dust cleaning assembly 5 is used to supply air into the filter cartridge 23 through the upper opening of the filter cartridge 23 so as to blow the dust adsorbed on the outer wall of the filter cartridge 23 into the ash hopper 3 .

[0048] The utility model provides a bottom-mounted assembled filter cartridge dust collector, which is provided with the dust box 1, dust collection component 2, ash hopper 3, main fan 4 and dust cleaning component 5 and other components, and the number of the filter cartridges 23 and the layout position in the dust collection space 12 are adjustable. In actual application, the dust-laden gas is first sucked into the ash hopper 3 by the main fan 4, and some large dust particles fall directly into the ash hopper 3. Thereafter, the dust-laden airflow is deflected upward by the impact of the wall panel and enters the dust collection space 12. At the same time, the flow rate is slowed down. Under the action of inertia and the dead weight of the dust, another part of the coarser dust particles fall directly into the ash hopper 3, which plays a role in pre-dust collection. The other lighter and finer dust is adsorbed on the outer wall of the filter cartridge 23 with the air flow upward, and the clean gas after being filtered by the filter cartridge 23 passes through the purification space and is discharged from the air outlet 11; and the light and fine dust adsorbed on the filter cartridge 23 is blown into the ash hopper 3 by the dust cleaning component 5; by setting the above structure, the utility model does not adopt screw fastening or welding when installing the filter cartridge 23, and the structural design of each part of the dust collector is compact, which will reduce labor costs. By setting the clamping component 22 for fixing the filter cartridge 23 to the orifice plate 21, the filter cartridge 23 can be easily cleaned and replaced.

[0049] To improve dust removal efficiency, the dust cleaning assembly 5 includes an air bag 51, a blow pipe 52, and a pulse valve 53. The air bag 51 is disposed in the dust removal box 1 and above the orifice plate 21. The blow pipe 52 is disposed at the top of the orifice plate 21, and its injection end extends into the purification space through the injection hole 211. The pulse valve 53 is disposed on the blow pipe 52 to control the airflow ejected from the injection end, thereby blowing dust adsorbed on the outer wall of the filter cartridge 23 into the ash hopper 3. By providing the air bag 51, the blow pipe 52, and the pulse valve 53, and adjusting the number of the filter cartridges 23 and their layout positions within the dust removal space 12, the filter cartridges 23 and the blow pipe 52 can be aligned one to one with each other, and one pulse valve 53 controls the opening and closing of one blow pipe 52, so as to adapt to different dust removal scenarios and improve dust removal efficiency.

[0050] To facilitate cleaning and replacement of the filter cartridge 23, the filter cartridge 23 includes a tray 231 and a cartridge body 232. The tray 231 is provided with a snap-fit ​​groove 2311 for fitting the cartridge body 232. The clamping assembly 22 is provided with at least two groups, each of which is spaced apart from the orifice plate 21. When the cartridge body 232 is fitted into the snap-fit ​​groove 2311, the clamping assembly 22 has a first state in which the tray 231 is pressed against the orifice plate 21, and a second state in which the tray 231 is released from the orifice plate 21. This design allows for stable and rapid installation and removal of the cartridge body 232. Screw-free fastening is avoided, reducing labor costs and preventing screws or nuts from falling into the filter cartridge 23, ensuring safety for the conveying equipment below the filter cartridge 23.

[0051] Among them, when the cylinder body 232 is sleeved on the clamping groove 2311, the clamping groove 2311 can limit the downward movement of the cylinder body 232. When the crimping piece 222 crimps the tray 231 to the frame, the tray 231 and the frame can limit the upward movement of the cylinder body 232. Therefore, through the cooperation of the tray 231 and the clamping assembly 22, the cylinder body 232 can be stably clamped in the set space.

[0052] Special note: The bottom-mounted assembled filter cartridge 23 refers to an installation method in which the filter cartridge 23 is installed upward below the orifice plate 21 and then fixed on the orifice plate 21.

[0053] To facilitate installation or removal of the filter cartridge 23, the pressing assembly 22 includes a support frame 221 and a crimping member 222. The support frame 221 is disposed at the bottom of the orifice plate 21. The crimping member 222 is disposed on the support frame 221 and is used to crimp the tray 231 to the frame. When the cartridge body 232 is sleeved in the engaging groove 2311, the crimping member 222 has a first state in which the tray 231 is crimped to the frame and a second state in which the tray 231 is released from the crimping. The crimping member 222 includes a rotating member 2221 and a pressing cam 2222. The rotating member 2221 is rotatably disposed on the support frame 221. The pressing cam 2222 is disposed on the outside of the rotating member 2221. The rotating member 2221 is used to drive the pressing cam 2222 to rotate and crimp the tray 231 to the frame, allowing the crimping member 222 to switch between the first and second states. Each of the rotating members 2221 is sequentially rotated on at least two of the support frames 221. The end of each rotating member 2221 extending outward from the support frame 221 through which it is inserted is set as a screwing end 22211, and the end of the screwing end 22211 is provided with a screwing nut 6. A limit plate 7 is fixed to the side wall of the support frame 221 near the screwing end 22211, and the screwing end 22211 is rotated and inserted into the limit plate 7, and the limit plate 7 is used to limit the movement stroke of the corresponding rotating member 2221 in the axial direction. Each of the crimping members 222 includes a plurality of clamping cams 2222, and the plurality of clamping cams 2222 are sequentially arranged on the outside of the rotating member 2221 along the axial direction of the corresponding rotating member 2221. The pressing cam 2222 includes a curved pressing surface 22221 and a flat locking surface 22222. The pressing surface 22221 and the locking surface 22222 are smoothly connected. When the pressing member 222 switches from the second state to the first state, the pressing surface 22221 is used to roll and press the tray 231, and the locking surface 22222 is used to press the tray 231 to the frame. In actual application, the rotating member 2221 is rotated by a torque wrench to drive the pressing cam 2222 to rotate and press the tray 231 to the frame, so that the pressing member 222 can switch between the first and second states, stably engaging the cartridge body 232 and facilitating installation or removal of the filter cartridge 23.

[0054] The setting of the limiting plate 7 can reduce the movement stroke of the rotating member 2221 in the axial direction, avoid the rotating member 2221 from being offset too much in the axial direction, and can stably clamp the cylinder body 232.

[0055] Among them, multiple clamping cams 2222 are set, so that there are more crimping points on the tray 231, and the crimping surface 22221 is larger. When one of the clamping cams 2222 fails, the other clamping cams 2222 can still crimp the tray 231 to the frame, thereby further stably clamping the cylinder body 232.

[0056] The arcuate surface and the locking surface 22222 are provided so that the crimping member 222 switches between the first state and the second state more smoothly, which is convenient for practical use.

[0057] Working principle: The dust-laden gas is first sucked into the ash hopper 3 by the main fan 4, and some large dust particles fall directly into the ash hopper 3. Then, the dust-laden airflow is turned upward by the impact of the wall panel and enters the dust removal space 12. At the same time, the flow rate slows down. Under the action of inertia and the weight of the dust, another part of the coarser dust particles falls directly into the ash hopper 3, which plays the role of pre-dust collection; other lighter and finer dust is adsorbed on the outer wall of the filter cartridge 23 with the air flow upward, and the clean gas after filtration by the filter cartridge 23 passes through the purification space and is discharged from the air outlet 11; and the light and fine dust adsorbed on the filter cartridge 23 is blown into the ash hopper 3 by the cleaning component 5.

[0058] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
