Description

Technical Field

[0001] This invention relates to the field of dust collector technology, specifically to a high-temperature dry dust collector. Background Technology

[0002] Hydrogen metallurgy, as a novel metallurgical process, reduces pollutant emissions from some traditional metallurgical processes by using hydrogen as a reducing agent. However, it still generates a large amount of dust during ore crushing, screening, sintering, and smelting. This dust contains metal oxides, carbon particles, and other harmful substances. If emitted directly without effective treatment, it will pollute the environment, affect the quality of life of surrounding residents, and pose a potential threat to the health of workers. Therefore, dust collectors are often used to treat the generated dust during processing. Current dust collectors use negative pressure suction to treat dust, and the gas enters the dust collector through the inlet. If the airflow velocity is too high, it will lead to uneven airflow distribution, causing hard particles (such as ore fragments) to be mixed in with the dust. This can cause localized wear of the filter bags (such as at the bag opening, bottom, and tube sheet), and in severe cases, holes may appear, leading to dust leakage. Summary of the Invention

[0017] Preferably, the striking component includes a folded rod fixed to the top of the skateboard, the other end of the folded rod extending into the interior of the cylinder and fixed with a striking block, and a connecting plate for cooperating with the striking block fixed to the bottom of the inner side of the cylinder's inner plate.

[0018] Preferably, it further includes a collection unit, the collection unit comprising:

[0019] A feeding box is connected to the bottom of the conical end of the cylinder, and a sealing plate slides through the inside of the feeding box;

[0020] A rotating rod is rotatably connected to the inside of the conical end of the cylinder, and a scraper is fixed to the other end of the rotating rod, the scraper being inclined.

[0023] The movable rod has one end that slides through the inside of the feeding box and is fixed to the sealing plate. The other end of the movable rod is fixed with a rack plate two, and the rack plate two is slidably connected to the top of the feeding box.

[0024] A transmission rod rotates through one side of the conical end of the cylinder. One end of the transmission rod is fixed with a second gear, and the bottom of the second gear meshes with a second rack plate.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] 1. In this invention, when gas passes through the air inlet pipe, it applies force to the impeller to rotate, which in turn drives the cam to rotate. As the cam rotates, it applies force to the push plate and drives the slide plate to slide on the top of the air inlet hood, thereby pushing the force plate and causing the rack plate to slide back and forth on the top of the air inlet hood. At the same time, the rack plate deflects at an angle on the air outlet plate, thereby preventing dust from directly impacting the bag filter element.

[0032] 2. As the slide moves, the invention also moves the folding rod, which in turn causes the hammer to strike the bottom of the tube sheet, thereby causing the filter bag to vibrate, making it easier to clean later.

[0033] 3. When cleaning dust, the present invention moves the moving rod along with the sealing plate as it is pulled, which in turn moves the rack plate and the gear. When the gear rotates, it drives the transmission rod and the bevel gear set to rotate as well. The rotating rod also rotates, which drives the scraper to scrape and clean the inner wall of the conical end of the cylinder, thereby improving the dust cleaning effect. Attached Figure Description

Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Please see Figure 1-9As shown, the high-temperature dry dust collector includes a cylinder 100, a bag filter element 200 installed inside the cylinder 100, a pulse cleaning device 300 located above the bag filter element 200 for blowing dust off it, and an air inlet 400 installed at the air inlet of the cylinder 100. The air inlet 400 includes an air inlet hood 410 connected to the left side of the cylinder 100. An air inlet pipe 420 is connected to the left side of the air inlet hood 410. Several air outlet plates 430 are arranged at equal intervals and rotate inside the air inlet hood 410. A force-applying component 440 and a reciprocating component 460 are respectively installed above the air inlet pipe 420 and the air inlet hood 410. The air inlet pipe 420 applies force to the force-applying component 440 through air intake. A striking component 450 for striking the tube sheet is installed above the force-applying component 440.

[0046] The force-applying component 440 includes a fan wheel 441 rotatably connected inside the top outer cover of the air inlet duct 420. The shaft of the fan wheel 441 extends to the outside and is fixed with a cam 442. A push plate 443 is hinged to one side of the protruding end of the cam 442, and a slide plate 444 is hinged to the other end of the push plate 443. The slide plate 444 is slidably connected to the top of the air inlet hood 410. Both ends of the slide plate 444 are fixed with sliders, and the sliders are slidably connected inside the groove at the top of the air inlet hood 410. This can provide auxiliary limiting for the slide plate 444 while maintaining its stability during movement. The top of 44 is hinged with a force-applying plate 445. When a large wind enters the air inlet duct 420, it will apply force to the impeller 441 to rotate, and drive the cam 442 to rotate. As the cam 442 rotates, when the protruding part rotates away from the push plate 443, it will pull the push plate 443. When it rotates to a position close to one end of the push plate 443, it will apply force to the push plate 443 and drive the slide plate 444 to slide on the top of the air inlet hood 410 so as to apply force to the force-applying plate 445. This achieves a reciprocating sliding effect.

[0047] A shield can also be provided on the top of the air intake shroud 410. The shield must completely cover the gear 464, and the rack plate 463 slides through the inside of the shield. This can protect the meshing parts of the gear 464 and the rack plate 463 from dust falling in and affecting their subsequent meshing.

[0048] The reciprocating component 460 includes a movable rod 461 fixed in a groove at the top of the air intake shroud 410. A spring 462 is sleeved on the surface of the movable rod 461, and both ends of the spring 462 are fixed to the inner wall of the groove and one side of the slide plate 444, respectively. A rack plate 463 is slidably connected to the top of the air intake shroud 410. One side of the rack plate 463 is hinged to the other end of the force application plate 445. A gear 464 is fixed on the rotating shaft surface at the top of the air outlet plate 430. One side of the rack plate 463 is hinged to the gear 464. The gears 464 mesh with each other. After the force plate 445 applies force, it will push the rack plate 463 and drive several gears 464 to rotate. At the same time, it will drive the air outlet plate 430 to deflect at an angle. When the air passes through the air outlet plate 430, the air will be circulated to avoid large direct impact. At the same time, as the air outlet plate 430 deflects at an angle, the air will impact and disperse to both sides, avoiding direct impact on the bag filter element 200 and affecting its service life.

[0049] The striking component 450 includes a folded rod 451 fixed to the top of the slide plate 444. The other end of the folded rod 451 extends into the interior of the cylinder 100 and is fixed with a striking block 452. A connecting plate 453 that works with the striking block 452 is fixed to the bottom of the inner tube sheet of the cylinder 100. When the slide plate 444 moves, it will also drive the folded rod 451 to move, and at the same time drive the striking block 452 to strike the connecting plate 453 at the bottom of the tube sheet. With the vibration of the tube sheet, the filter element 200 on the tube sheet will vibrate, so that the impurities solidified on the surface of the filter element 200 can be loosened, so as to facilitate the subsequent pulse cleaning of the surface of the filter element 200 by the pulse cleaning device 300.

[0050] Based on the above scheme, see Figure 5 and Figure 7It also includes a collection unit 500, which includes a feeding box 510 connected to the bottom of the conical end of the cylinder 100. A sealing plate 520 slides through the inside of the feeding box 510. A scraper is installed at the front end of the inner cavity of the feeding box 510 and is inclined so that when the sealing plate 520 is pulled outward each time, the top scraper can scrape the top of the sealing plate 520. A rotating rod 540 is rotatably connected inside the conical end of the cylinder 100. A protective shell 536 is fixedly connected to the top of the feeding box 510. A gear 532 is located inside the protective shell 536. This arrangement allows for the cleaning of gear 532. 2. A shield is provided to prevent external dust from falling into the meshing area of ​​gear 2 532 and rack plate 2 535. A scraper 550 is fixed to the other end of the rotating rod 540. The scraper 550 is set at an angle. A transmission component 530 for applying force to rotate the rotating rod 540 is installed on one side of the sealing plate 520. When cleaning dust, the sealing plate 520 can be pulled. As the sealing plate 520 moves outward, it will apply force to rotate the rotating rod 540 through the transmission component 530, and drive the scraper 550 to rotate and scrape the inner wall of the conical end of the cylinder 100. The scraped dust will fall downward to improve the cleaning effect.

[0051] The transmission component 530 includes a movable rod 531, one end of which slides through the interior of the feeding box 510 and is fixed to the sealing plate 520. A rack plate 535 is fixed to the other end of the movable rod 531, and the rack plate 535 is slidably connected to the top of the feeding box 510. A transmission rod 533 rotatably passes through one side of the conical end of the cylinder 100. A gear 532 is fixed to one end of the transmission rod 533, and the bottom of the gear 532 meshes with the rack plate 535. A bevel gear set 534 is fixed to one end of the bevel teeth on one side of the transmission rod 533, and the other bevel teeth are fixed to the bottom of the rotating rod 540. The interior of the conical end of the cylinder 100 is fixed by a fixing rod. A protective shell 537 is provided, and the bevel gear set 534 is located inside the protective shell 537. This can shield and protect the bevel gear set 534, preventing dust from falling directly onto the surface of the bevel gear set 534 and affecting its subsequent use. When the sealing plate 520 moves outward, it will drive the moving rod 531 to move together, and at the same time drive the rack plate 535 to move, and drive the gear 532 to rotate. When the gear 532 rotates, it will drive the transmission rod 533 and the bevel gear set 534 to rotate as well. The rotating rod 540 will also rotate, and drive the scraper 550 to scrape and clean the inner wall of the conical end of the cylinder 100.

[0052] The collecting unit 500 also includes a limiting member 560, which includes an insert plate 561 that slides through the front surface of the sealing plate 520. Insert blocks 562 are fixed on both sides of the surface of the feeding box 510. The other end of the insert plate 561 slides through the interior of the insert block 562. Before the sealing plate 520 is pulled out, force can be applied upward to the insert plate 561, and the two ends of the insert plate 561 will be disengaged from the interior of the insert block 562, so as to facilitate the pulling out of the sealing plate 520.

[0053] Working principle: In use, the sealing plate 520 can be connected to the external dust inlet pipe. Then, through the exhaust device on the right side of the cylinder 100, a negative pressure is generated inside the cylinder 100. Dust then enters through the air inlet pipe 420, which applies force to the impeller 441 to rotate, and drives the cam 442 to rotate. As the cam 442 rotates, it applies force to the push plate 443, and drives the slide plate 444 to slide on the top of the air inlet hood 410, thereby pushing the force plate 445 and causing the rack plate 463 to slide back and forth on the top of the air inlet hood 410. At the same time, the rack plate 463 deflects the air outlet plate 430 at an angle, thereby preventing dust from directly impacting the bag filter element 200. Subsequently, the dust is filtered by the bag filter element 200. Dust and impurities adhere to the surface of the filter element 200. After multiple uses, the filter element 200 can be pulse-cleaned by the pulse cleaning device 300. The blown-off dust will fall into the feed box 510. During cleaning, the limiting member 560 can be used to release the limiting of the sealing plate 520. Then, pulling the sealing plate 520 will move the moving rod 531, move the rack plate 535, and rotate the gear 532. When the gear 532 rotates, it will drive the transmission rod 533 and the bevel gear set 534 to rotate. The rotating rod 540 will also rotate, and drive the scraper 550 to scrape and clean the inner wall of the conical end of the cylinder 100 to improve the cleaning effect.
