Description

Technical Field

[0001] The utility model relates to the technical field of pulse bag dust collectors, in particular to a pulse bag dust collector with an anti-clogging function. Background Art

[0002] When the pulse bag dust collector is working normally, the dust-laden gas enters the ash hopper from the air inlet. Due to the rapid expansion of the gas volume, some coarser dust particles fall into the ash hopper due to inertia or natural sedimentation, and most of the remaining dust particles rise with the air flow into the bag chamber. After being filtered by the filter bag, the dust particles are retained on the outside of the filter bag. The purified gas enters the upper box from the inside of the filter bag, and is then discharged into the atmosphere through the valve plate hole and the exhaust port, thereby achieving the purpose of dust removal.

[0003] In the existing technology, during the dust collection process of the pulse bag dust collector, if the exhaust gas is humid and contains a lot of water vapor, the humid gas mixed with dust particles is easy to adhere to the wall of the dust filter bag, which may cause blockage and the exhaust air quality cannot be guaranteed.

[0004] The existing patent (Announcement No.: CN212700976U) discloses a pulse bag dust collector with an anti-clogging function. The setting of the resistance wire heating mesh cover can dry out moisture, preventing the moist gas from mixing with dust particles and adhering to the wall of the dust filter bag. On the one hand, it can improve the cleaning effect and facilitate dust discharge. On the other hand, it can prevent the dust collector from being blocked and ensure its normal operation. The setting of the activated carbon filter cotton in the filter can filter the exhaust gas to ensure the quality of the exhausted air. The setting of the agitator can increase the dust discharge rate and prevent the ash discharge port from being blocked.

[0005] To address this issue, existing patents propose a solution that uses a resistance wire to heat the mesh to dry the air, preventing dust from adsorbing onto the dust filter bag and causing clogging. However, in actual use, dust may adhere to the resistance wire heating mesh, which not only affects the drying effect but can also accumulate over time, eventually leading to clogging.

[0026] 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.

[0027] The utility model provides a technical solution:

[0028] See also Figures 1 to 4 , a pulse bag dust collector with anti-clogging function, including a dust removal shell 1, a dust falling shell 2 is fixedly installed below the dust removal shell 1, an exhaust pipe 4 is penetrated into the outer wall of the dust removal shell 1, an air inlet pipe 3 is penetrated into the outer wall of the dust falling shell 2, a support frame 5 is fixedly installed inside the ash falling shell 2, a heating resistor network 6 is embedded in the interior of the support frame 5, and a cleaning mechanism 7 is provided below the heating resistor network 6; the cleaning mechanism 7 includes a motor 701, the motor 701 is embedded in one side of the outer wall of the ash falling shell 2, the power output end of the motor 701 is connected to a worm gear assembly 702, a drive rod 703 is penetrated from the inside of the worm gear assembly 702, and a mounting shell 704 is fixedly installed on the top of the drive rod 703, and the mounting shell 704 is embedded inside. It is equipped with an electromagnet 705, and the top of the mounting shell 704 is slidably connected to a permanent magnet block 706. A load-bearing rod 707 passes through the inside of the heating resistor net 6, and a scraper 708 is fixed to the outer wall of one end of the load-bearing rod 707 that passes through the heating resistor net 6. The permanent magnet block 706 passes through the inside of the load-bearing rod 707, and a sliding structure is formed between the permanent magnet block 706 and the mounting shell 704. The scraper 708 fits tightly against the heating resistor net 6, and a sliding structure is formed between the scraper 708 and the heating resistor net 6. The outer wall of the driving rod 703 is rotatably connected to the sleeve 8, and the outer wall of the sleeve 8 is fixedly installed with a fixing plate 9. A spring 10 is embedded on one side of the permanent magnet block 706 at the top of the mounting shell 704, and a resistance block 11 is fixedly installed on the top of the spring 10.

[0029] By adopting the above technical solution, the exhaust gas entering the ash falling shell 2 through the air intake pipe 3 is first dried and dehumidified by the heating resistor net 6 embedded in the support frame 5, and then rises to the dust removal shell 1 for dust removal, and is discharged through the exhaust pipe 4. After being started by the electromagnet 705, the permanent magnet block 706 with the same magnetic pole is pushed, and the bearing rod 707 is slid into the installation shell 704, and the scraper 708 is allowed to contact the heating resistor net 6. After cooling, scraping and cleaning can be performed to avoid blockage. The adjustment and control of the electromagnet 705 can prevent the heating resistor net 6 from overheating and causing damage to the brush of the scraper 708. The motor 701 drives the worm gear assembly 702, so that the drive rod 703 can rotate stably under the support of the sleeve 8 and the fixed plate 9, thereby driving the scraper 708 to rotate to clean the heating resistor net 6 to avoid blockage. When cleaning is completed, the electromagnet 705 is closed and the elastic contraction of the spring 10 drives the resistance block 11 to reset the permanent magnet block 706.

[0030] Specifically, such as Figure 2 and Figure 5As shown, a scraping mechanism 12 is provided above the heating resistor net 6, and the scraping mechanism 12 includes a connecting plate 1201, which is fixedly mounted on the top of the load-bearing rod 707, and an extension plate 1202 is fixedly mounted on the outer wall of the connecting plate 1201, and a telescopic block 1203 is passed through the bottom end of the extension plate 1202, and a placement groove 1204 is provided between the support frame 5 and the heating resistor net 6, and the telescopic block 1203 fits tightly with the heating resistor net 6, and a sliding structure is formed between the heating resistor net 6 and the telescopic block 1203.

[0031] By adopting the above technical solution, the connecting plate 1201 is used to prevent the supporting rod 707 from being detached. When the supporting rod 707 rises to allow the scraper 708 brush to fit the heating resistor net 6, the telescopic block 1203 embedded in the extension plate 1202 is telescoped and abuts against the top of the heating resistor net 6, thereby scraping off the dust above, etc., and detaching from the placement groove 1204 and entering the dust removal shell 2.

[0032] Working principle: After the exhaust gas enters the dust collecting shell 2 through the air inlet pipe 3, it is dried and dehumidified by the heating resistance net 6 embedded in the support frame 5, and then enters the dust collecting shell 1, is filtered by the filter bag, and is finally discharged through the exhaust pipe 4. When cleaning is required, the electromagnet 705 is first started to push the permanent magnet block 706 with the same magnetic pole to slide along the mounting shell 704, so that the permanent magnet block 706 penetrates the bearing rod 707, and then the motor 701 is started to rotate the drive rod 703 through the worm gear assembly 702, thereby driving the mounting shell 704, and allowing the brush on the scraper 708 to fit the heating resistance net 6 for brushing and cleaning. When the permanent magnet block 706 cannot align with the reserved hole of the bearing rod 707, it can be driven by the motor 701 to adjust the angle for penetration. When drying is in progress, the electric motor is closed. The magnet 705 prevents the brush from sticking to the heating resistor net 6 and causing damage. It rotates and engages with the drive rod 703 through the sleeve 8 and is fixed inside the dust removal shell 2 with the fixing plate 9, thereby maintaining the stable rotation of the drive rod 703. When the electromagnet 705 is closed, the elastic contraction of the spring 10 drives the resistance block 11 to reset the permanent magnet block 706. When the bearing rod 707 slides, it is prevented from separating from the heating resistor net 6 through the connecting plate 1201. At the same time, when the bearing rod 707 lifts the connecting plate 1201, the telescopic block 1203 embedded in the extension plate 1202 is extended and retracted, and contacts the top of the heating resistor net 6, thereby following the rotation of the bearing rod 707 to scrape off the adsorbed dust, etc., and separate from the placement groove 1204 and enter the dust removal shell 2, and finally discharged through the valve set at the bottom.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
