Description

Technical Field

[0001] This utility model relates to the technical field of cartridge dust collectors, specifically a cartridge dust collector with moisture-proof function. Background Technology

[0002] Cartridge dust collectors are industrial dust removal equipment that uses filter cartridges as the core filtration element and pulse jet cleaning technology for dust separation. They are mainly used to remove industrial dust and particles. However, in ordinary dust collectors, if the dust being processed encounters moisture, it absorbs water and becomes damp and sticky, adhering firmly to the surface of the filter cartridge and clogging the micropores of the filter media. This causes the fan to have to work harder to "pump air," increasing energy consumption. At the same time, the pulse jet cleaning system cannot shake off the sticky dust, resulting in ineffective dust removal. Furthermore, a humid environment accelerates the corrosion of the filter cartridge frame and may also cause the filter media itself to hydrolyze, mold, and be damaged. In order to improve the efficiency of cartridge dust collectors, a cartridge dust collector with moisture-proof function is needed. However, existing cartridge dust collectors with moisture-proof function still have the following shortcomings.

[0003] When existing cartridge dust collectors are in use, most lack moisture-proof structures. As a result, when humid, high-temperature flue gas enters the cold dust collector housing, the temperature drops below the dew point. Water precipitates and condenses on the filter cartridges and the inner wall of the housing. The condensed water vapor mixes with dust to form a muddy paste that firmly blocks the micropores of the filter cartridge fibers, affecting the overall dust removal efficiency. At the same time, some dust particles combine with water to form corrosive substances, which corrode the filter cartridge fibers and metal frame, shortening the service life of the filter cartridges. This leads to a decrease in the practicality and efficiency of the cartridge dust collector. Utility Model Content

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figure 1 , Figure 2 and Figure 3As shown, a cartridge dust collector with moisture-proof function includes a dust collection box 1 and a moisture-proof component 3. A dust hopper 2 is located at the bottom of the dust collection box 1. The moisture-proof component 3 is located on the left side of the outside of the dust collection box 1. The moisture-proof component 3 includes a moisture-proof box 301, an air inlet 302, a servo motor 303, a bevel gear 304, a support rod 305, a mounting crossbar 306, a cleaning brush 307, an electric heating block 308, and a polytetrafluoroethylene (PTFE) cylinder 309. An air inlet 302 is located at the outer end of the moisture-proof box 301, and a servo motor 303 is installed at the upper middle part of the air inlet 302. The front end of the servo motor 303 is connected to a bevel gear 304. A support rod 305 is connected to the front end of wheel 304. A mounting crossbar 306 is installed on the outside of the support rod 305, and a cleaning brush 307 is provided at the front end of the mounting crossbar 306. An electric heating block 308 is installed inside the moisture-proof box 301, close to the inner wall, and a polytetrafluoroethylene (PTFE) cylinder 309 is provided inside the electric heating block 308. The mounting crossbar 306 and the cleaning brush 307 are arranged perpendicularly, and the cleaning brush 307 is fixedly connected to the mounting crossbar 306 by bolts. The cleaning brush 307 and the PTFE cylinder 309 are embedded in each other, and the outer surface of the cleaning brush 307 is in close contact with the inner surface of the PTFE cylinder 309. The number of cleaning brushes 307 is set as follows. There are three cleaning brushes 307, equidistantly distributed on the outside of the support rod 305. The dehumidifying box 301 is fixedly installed on the left side of the dust collector 1 using fastening bolts. The air inlet 302, in conjunction with the dehumidifying box 301, delivers filtered air into the dust collector 1. The output shaft of the servo motor 303 at the upper end of the air inlet 302 is connected to a bevel gear 304 via a coupling. The operation of the servo motor 303 drives the bevel gear 304 to rotate, causing the support rod 305, connected to the outside of the bevel gear 304, to rotate inside the dehumidifying box 301. The cleaning brushes 307 are fixedly installed on the outside of the support rod 305 using a mounting crossbar 306. 05 The rotating and cooperating crossbar 306 drives the cleaning brush 307 to rotate inside the PTFE cartridge 309. The electric heating block 308 installed inside the dehumidification box 301 actively maintains the internal temperature of the box above the dew point from the air inlet 302, thereby preventing the generation of condensation. In order to prevent dust-laden gas from adhering to the surface of the electric heating block 308 when passing through the dehumidification box 301, the PTFE cartridge 309 is installed inside the electric heating block 308. The rotation of the cleaning brush 307 is used to treat the dust adhering to the inner surface of the PTFE cartridge 309, thereby improving the overall practicality and efficiency of the cartridge dust collector.

[0023] like Figure 1 , Figure 3 and Figure 4As shown, an installation assembly 4 is provided at the upper part of the dust collector 1. The installation assembly 4 includes a mounting top plate 401, an outer mounting ring 402, a mounting groove 403, a mounting slider 404, and a mounting block 405. The lower end of the mounting top plate 401 is provided with an outer mounting ring 402, and mounting grooves 403 are opened on both sides inside the outer mounting ring 402. The mounting slider 404 is connected inside the mounting groove 403, and the mounting block 405 is installed on the outside of the mounting slider 404. The installation assembly 4 also includes a filter. The filter cylinder 406, return spring 407, and pressure plate 408 are arranged. The lower end of the mounting block 405 is provided with the filter cylinder 406. The return spring 407 is installed inside the outer mounting ring 402, and the front end of the return spring 407 is provided with the pressure plate 408. The internal dimensions of the mounting groove 403 are adapted to the external dimensions of the mounting slider 404, and the mounting slider 404 is rotatably connected to the outer mounting ring 402 through the mounting groove 403. The return spring 407 and the pressure plate 408 are arranged perpendicularly, and the pressure plate 408 is connected to the outer mounting ring 402 through the mounting groove 403. The positioning spring 407 is elastically connected to the mounting top plate 401. The mounting top plate 401 is fixedly installed inside the dust collector 1 at the upper end by fastening bolts. The outer mounting ring 402 is fixedly installed at the lower end of the air guide groove of the mounting top plate 401 in conjunction with the fastening bolts. The return spring 407 is fixedly installed inside the outer mounting ring 402. The return spring 407 makes the pressure plate 408 elastically connected to the mounting top plate 401. The internal dimensions of the mounting groove 403 opened inside the outer mounting ring 402 are adapted to the external dimensions of the mounting slider 404 added to the outside of the mounting block 405. Thus, the mounting block 405 is rotated and installed inside the outer mounting ring 402 by the mounting groove 403 and the mounting slider 404, thereby completing the fixation of the filter cartridge 406. After installation, the pressure plate 408 and the return spring 407 press tightly against the mounting block 405 to prevent the mounting block 405 from shifting position. This makes the installation of the filter cartridge 406 convenient and stable, improving the flexibility of the cartridge dust collector during use.

[0024] In summary, this moisture-proof cartridge dust collector, during use, firstly collects settled dust particles through the ash hopper 2 at the bottom of the dust collection box 1. Then, the mounting top plate 401 is fixed to the upper part of the dust collection box 1 using fastening bolts, and the outer mounting ring 402 is installed at the lower end of the air guide groove of the mounting top plate 401. Next, through the cooperation of the mounting slide 403 and the mounting slider 404, the mounting block 405 is rotated and installed inside the outer mounting ring 402, thus completing the fixing of the filter cartridge 406. After installation, the pressure plate 408, under the action of the return spring 407, presses tightly against the mounting block 405 to prevent displacement, ensuring that the filter cartridge 406 is installed conveniently and stably. Furthermore, the moisture-proof box 301 is fixedly installed on the left side of the outside of the dust collection box 1 using fastening bolts. External dust-laden gas enters the moisture-proof box 301 through the air inlet 302, and after pre-drying... After processing, the material is sent into the dust collection box 1. The servo motor 303 at the top of the moisture-proof box 301 starts, driving the bevel gear 304 to rotate. This causes the support rod 305 connected to it to rotate inside the moisture-proof box 301. The support rod 305 drives the cleaning brush 307 to rotate continuously on the inner wall of the PTFE cylinder 309 via the installed crossbar 306. To effectively prevent moisture, the moisture-proof box 301 is equipped with an electric heating block 308. After it starts working, it can maintain the temperature inside the box above the dew point, fundamentally preventing the generation of condensate. To avoid dust-laden gas contaminating the surface of the electric heating block 308, a PTFE cylinder 309 is installed inside it. The PTFE cylinder 309 has excellent non-stick and corrosion resistance. Together with the continuously rotating cleaning brush 307, it can automatically remove the dust adhering to the inner wall, ensuring heating efficiency and moisture-proof effect, thereby improving the practicality and overall operating efficiency of the entire cartridge dust collector.
