[0014] Further, for the method of an explosion-proof filter cartridge dust collector, the method steps are as follows:

[0015] S1: Gas pressure relief;

[0016] S2: Blowing and air supplementing;

[0017] S3: Sealed jetting;

[0018] S4: Filter element cleaning.

[0019] The present invention has the following beneficial effects:

[0020] (1) For the explosion-proof filter cartridge dust collector of the present invention, when cleaning dust and impurities, due to the continuous operation of the exhaust fan, gas will continuously enter from the left end of the exhaust pipe. At this time, the flue in the exhaust pipe has been blocked, and the gas will enter the pressure relief area. As the gas accumulates more and more, the air pressure in the pressure relief area will continuously increase. The gas drives the rectangular pressure relief plate to rise, and at this time, the pressure relief spring will undergo tensile deformation. If the cleaning work has not been completed, when the air pressure in the pressure relief area reaches a certain threshold, the gas will enter the L-shaped groove through the pressure relief hole and push the strip-shaped pressure relief plate to rise. At this time, the pressure relief spring II will undergo compressive deformation. When the height of the strip-shaped pressure relief plate is higher than the narrower area of the L-shaped groove, the gas will flow into the pressure relief rectangular block from the narrower area, and the gas will be discharged from the pressure relief rectangular block. At this time, the pressure relief of the accumulated gas in the pressure relief area is completed, avoiding explosion caused by excessive air pressure in the pressure relief area plus the influence of dust and static electricity, resulting in casualties and economic losses of personnel;

[0021] (2) For the explosion-proof filter cartridge dust collector of the present invention, when it is necessary to clean dust and impurities, start the hydraulic cylinder. The hydraulic cylinder drives the U-shaped plate to move away from the hydraulic cylinder. The U-shaped plate quickly squeezes the gas in the U-shaped air box and pushes it into the L-shaped air inlet pipe. The gas will enter the sliding air pipe from the L-shaped air inlet pipe and then enter the rectangular limiting groove from the sliding air pipe. After the U-shaped plate is pushed to a certain position, the hydraulic cylinder will drive the U-shaped plate to return. At this time, the gas on the right side of the U-shaped plate will be discharged from the air exchange hole. When the U-shaped plate returns past the air exchange hole, the outside air will be replenished into the U-shaped air box from the air exchange hole again to prepare for the next cleaning on the left side of the U-shaped plate;

[0022] (3) In the explosion-proof filter cartridge dust collector of the present invention, the more gas enters the rectangular limiting groove, the stronger the gas pressure will be generated. The gas will push the L-shaped sealing plate down. At this time, the circular ventilation groove on the L-shaped sealing plate will leave the exhaust pipe. At this time, the exhaust pipe will be closed and blocked by the L-shaped sealing plate. The corresponding L-shaped sealing plate will also drive the rectangular sealing plate to leave the through groove, so that the through groove is connected to the outside. Since the right side of the T-shaped circular plate is supported by the exhaust pipe under normal conditions, the T-shaped circular plate will not leave the outside of the L-shaped sealing plate when the gas enters the rectangular limiting groove, thereby ensuring the stable descent of the L-shaped sealing plate. After the T-shaped circular plate enters the exhaust pipe and is not blocked by the exhaust pipe, the T-shaped circular plate will leave the L-shaped sealing plate under the action of air pressure. At this time, a large amount of air will be discharged from the gap between the T-shaped circular plate and the rectangular limiting groove;

[0023] (4) The present invention provides an explosion-proof filter cartridge dust collector. After the gas enters the smoke exhaust pipe, it will be blown through the perforated circular plate to sweep the left side and outer wall of the filter element, blowing off the impurities and dust on the filter element. The strong wind will also blow the filter element to move in the direction close to the annular plate. At this time, the telescopic spring will be stretched and deformed. After the filter element is exposed to the strong wind, it will move rapidly and hit the annular plate. After cleaning, the filter element will also be driven back by the elastic force of the telescopic spring and cause the contact plate to hit the perforated circular plate. During the two round-trip collisions, the dust on the filter element will be shaken off, thereby improving the cleaning effect of the filter element. The fallen dust and impurities will be discharged from the through groove to ensure the cleanliness of the pressure release area and the filter element.

[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] As Figure 2 and Figure 5 shown, an L-shaped sealing plate 507 is slidably installed in the exhaust pipe 1, the L-shaped sealing plate 507 penetrates through the exhaust pipe 1, a limiting spring 508 is fixedly installed on the bottom inner wall of the L-shaped sealing plate 507, the top end of the limiting spring 508 is fixedly connected to the exhaust pipe 1, a through groove 509 is formed in the exhaust pipe 1, a rectangular sealing plate 510 is fixedly installed on the top of the L-shaped sealing plate 507, and the rectangular sealing plate 510 extends into the through groove 509 and is slidably connected to the through groove 509.

[0040] The exhaust pipe 1 will be closed and blocked by the L-shaped sealing plate 507, and correspondingly, the L-shaped sealing plate 507 will also drive the rectangular sealing plate 510 to leave the through groove 509, so that the through groove 509 communicates with the outside.

[0041] As Figure 2 shown, an activity mechanism 6 is arranged on the top of the exhaust pipe 1, the activity mechanism 6 includes a hydraulic cylinder 601 fixedly installed on the top of the exhaust pipe 1 and a U-shaped air box 602, the output end of the hydraulic cylinder 601 extends into the U-shaped air box 602 and is slidably connected to the U-shaped air box 602, a plurality of air exchange holes 6021 are respectively formed in the front and back of the U-shaped air box 602, a U-shaped plate 603 is fixedly installed at the output end of the hydraulic cylinder 601, the U-shaped plate 603 is slidably connected to the U-shaped air box 602, and an L-shaped air inlet pipe 604 is fixedly installed on the top of the U-shaped air box 602.

[0042] When it is necessary to clean the dust and impurities, the hydraulic cylinder 601 is started, the hydraulic cylinder 601 drives the U-shaped plate 603 to move in a direction away from the hydraulic cylinder 601, and the U-shaped plate 603 quickly squeezes the gas in the U-shaped air box 602 and pushes it into the L-shaped air inlet pipe 604.

[0043] As Figure 6As shown, a circular ventilation groove 605 is formed on the L-shaped sealing plate 507, a rectangular limiting groove 606 is formed inside the L-shaped sealing plate 507, a sliding air duct 607 is fixedly installed inside the L-shaped sealing plate 507, the sliding air duct 607 communicates with the rectangular limiting groove 606, and the bottom end of the L-shaped air inlet duct 604 extends into the sliding air duct 607 and is slidably connected to the sliding air duct 607.

[0044] The gas will enter the sliding air duct 607 from the L-shaped air inlet duct 604 and then enter the rectangular limiting groove 606 from the sliding air duct 607. After the U-shaped plate 603 is pushed to a certain position, the hydraulic cylinder 601 will drive the U-shaped plate 603 to return. At this time, the gas on the right side of the U-shaped plate 603 will be discharged from the air exchange hole 6021. When the U-shaped plate 603 returns past the air exchange hole 6021, the outside air will replenish the left side of the U-shaped plate 603 in the U-shaped air box 602 again to prepare for the next cleaning.

[0045] As Figure 6 shown, a movable spring 608 is fixedly installed on the left inner wall of the rectangular limiting groove 606. The right end of the movable spring 608 is fixedly installed with a T-shaped circular plate 609. The right side of the T-shaped circular plate 609 extends outside the L-shaped sealing plate 507 and is slidably connected to the L-shaped sealing plate 507. A plurality of limiting blocks 610 are fixedly installed on the inner wall of the smoke exhaust pipe 1.

[0046] After the T-shaped circular plate 609 enters the smoke exhaust pipe 1 without being blocked by the smoke exhaust pipe 1, the T-shaped circular plate 609 will leave the L-shaped sealing plate 507 under the action of air pressure. At this time, a large amount of air will be discharged from the gap between the T-shaped circular plate 609 and the rectangular limiting groove 606.

[0047] As Figure 5 shown, a vibration mechanism 7 is arranged in the smoke exhaust pipe 1. The vibration mechanism 7 includes a perforated circular plate 701 fixedly installed in the smoke exhaust pipe 1. An annular plate 702 is fixedly installed in the smoke exhaust pipe 1. Two limiting circular rods 703 are fixedly installed on the right side of the perforated circular plate 701. The right ends of the two limiting circular rods 703 are fixedly connected to the annular plate 702.

[0048] After the gas enters the smoke exhaust pipe 1, it will blow the left side and the outer wall of the filter element 704 through the perforated circular plate 701, blowing off the impurities and dust on the filter element 704. The strong wind will also blow the filter element 704 to move towards the annular plate 702.

[0049] As Figure 5 shown, a filter element 704 is slidably sleeved on the two limiting circular rods 703. A contact plate 705 is fixedly installed on the outer wall of the filter element 704. Two telescopic springs 706 are fixedly installed on the right side of the perforated circular plate 701. The right ends of the two telescopic springs 706 are fixedly connected to the filter element 704.

[0050] After the filter element 704 comes into contact with strong wind, it will move rapidly and strike the annular plate 702. After cleaning, the filter element 704 will also drive the filter element 704 to return under the elastic force of the telescopic spring 706 and cause the contact plate 705 to strike the perforated circular plate 701. During the two impacts back and forth, the dust on the filter element 704 will be shaken off, thereby improving the cleaning effect of the filter element 704. The fallen dust and impurities will be discharged from the through groove 509 to ensure the cleanliness inside the pressure relief area 2 and the filter element 704.

[0051] As Figure 1 - Figure 8 shown, a method for an explosion-proof cartridge dust collector is as follows:

[0052] S1: Gas pressure relief;

[0053] S2: Blowing and air replenishment;

[0054] S3: Sealed jet;

[0055] S4: Cleaning of the filter element 704.

[0056] When cleaning dust and impurities, due to the continuous operation of the exhaust fan, gas will be continuously input from the left end of the exhaust pipe 1. At this time, the flue in the exhaust pipe 1 has been blocked, and the gas will enter the pressure relief area 2. As the gas accumulates more and more, the air pressure in the pressure relief area 2 will continue to rise. The gas drives the rectangular pressure relief plate 3 to rise so sad, and at this time the pressure relief spring one 501 will undergo a tensile deformation. If the cleaning work has not been completed, when the air pressure in the pressure relief area 2 reaches a certain threshold, the gas will enter the L-shaped groove 502 through the pressure relief hole 504 and push the strip-shaped pressure relief plate 506 to rise. At this time, the pressure relief spring two 505 will undergo a compression deformation. When the height of the strip-shaped pressure relief plate 506 is higher than the narrower area of the L-shaped groove 502, the gas will flow into the pressure relief rectangular block 503 from the narrower area, and the gas will be discharged from the pressure relief rectangular block 503. At this time, the pressure relief of the accumulated gas in the pressure relief area 2 is completed, avoiding explosion caused by too high air pressure in the pressure relief area 2 and the influence of dust and static electricity, resulting in casualties and economic losses of personnel; When it is necessary to clean dust and impurities, start the hydraulic cylinder 601. The hydraulic cylinder 601 drives the C-shaped plate 603 to move away from the hydraulic cylinder 601. The C-shaped plate 603 quickly squeezes the gas in the C-shaped air box 602 and pushes it into the L-shaped air inlet pipe 604. The gas will enter the sliding air pipe 607 from the L-shaped air inlet pipe 604 and then enter the rectangular limit groove 606 from the sliding air pipe 607. After the C-shaped plate 603 is pushed to a certain position, the hydraulic cylinder 601 will drive the C-shaped plate 603 to return. At this time, the gas on the right side of the C-shaped plate 603 will be discharged from the air exchange hole 6021. When the C-shaped plate 603 returns past the air exchange hole 6021, the outside air will be replenished into the C-shaped air box 602 again from the air exchange hole 6021 to prepare for the next cleaning on the left side of the C-shaped plate 603;

[0057] The more gas that enters the rectangular limiting groove 606, the stronger air pressure will be generated, and the gas will push the L-shaped sealing plate 507 down. At this time, the circular ventilation groove 605 on the L-shaped sealing plate 507 will leave the smoke exhaust pipe 1. At this time, the smoke exhaust pipe 1 will be closed and blocked by the L-shaped sealing plate 507. The corresponding L-shaped sealing plate 507 will also drive the rectangular sealing plate 510 to leave the through groove 509, so that the through groove 509 is connected to the outside. Because the right side of the T-shaped circular plate 609 is supported by the smoke exhaust pipe 1 under normal conditions, when the gas enters the rectangular limiting groove 606, the T-shaped circular plate 609 will not leave the outside of the L-shaped sealing plate 507, ensuring the stable descent of the L-shaped sealing plate 507. After the T-shaped circular plate 609 enters the smoke exhaust pipe 1 and is not blocked by the smoke exhaust pipe 1, the T-shaped circular plate 609 will leave the L-shaped sealing plate 507 under the action of air pressure. At this time, a large amount of air The gas will be discharged from the gap between the T-shaped circular plate 609 and the rectangular limiting groove 606; after the gas enters the smoke exhaust pipe 1, it will be blown through the perforated circular plate 701 to the left side and outer wall of the filter element 704, and the impurities and dust on the filter element 704 will be blown off. The strong wind will also blow the filter element 704 to move in the direction close to the annular plate 702. At this time, the telescopic spring 706 will be stretched and deformed. After being exposed to the strong wind, the filter element 704 will move rapidly and hit the annular plate 702. After cleaning, the filter element 704 will also be driven back by the elastic force of the telescopic spring 706 and make the contact plate 705 hit the perforated circular plate 701. During the two back and forth collisions, the dust on the filter element 704 will be shaken off, thereby improving the cleaning effect of the filter element 704. The fallen dust and impurities will be discharged from the through groove 509 to ensure the cleanliness of the pressure release area 2 and the filter element 704.
