Description

Technical Field

[0001] The present invention relates to the technical field of dust removal filter bags, and specifically relates to a new type of filter bag with high temperature resistance and corrosion resistance. Background Art

[0002] With the rapid development of the global industry, various industrial production activities such as iron and steel smelting, cement manufacturing, thermal power generation, and chemical production are increasing day by day. These industrial processes will generate a large amount of dust. If directly discharged into the atmosphere without effective treatment, it will not only cause serious pollution to the surrounding environment, affecting air quality, soil quality, and water quality, but also endanger human health, causing various health problems such as respiratory diseases and cardiovascular diseases.

[0003] As the core component of bag dust removal technology, the dust removal filter bag can effectively filter the dust in the gas. However, after the filter bag is used for a period of time, the surface of the filter bag will be covered with accumulated dust, resulting in a decline in the filtering performance of the filter bag.

[0004] The existing filter bag is provided with nozzles. Compressed gas is ejected from the nozzles to clean the accumulated dust on the filter bag. However, during the operation of the equipment, vibrations will occur. Under the interference of the vibrations, the position of the nozzles will shift during operation, which will cause the compressed gas ejected from the nozzles to be unevenly distributed on the filter bag, resulting in poor dust cleaning effect in some areas of the filter bag and difficult removal of dust in some areas, thus affecting the filtering effect of the filter bag.

[0040] Referring to Figure 1-9 , for the first embodiment of the present invention, a new type of high-temperature and corrosion-resistant filter bag is provided. This new type of high-temperature and corrosion-resistant filter bag includes a filter bag 1. A support skeleton 11 is arranged inside the filter bag 1. The filter bag 1 is preferably made of polyimide composite needle felt, which has outstanding high-temperature resistance and can effectively ensure the structural stability and filtration performance of the filter bag 1 in a high-temperature industrial environment.

The second magnet 17 can contact with the ball 152. When the second magnet 17 slides along the second slide groove 15, the second magnet 17 will move the ball 152 to make the ball 152 rotate in the rolling groove 151. The rotation of the ball 152 in the rolling groove 151 can reduce the friction resistance of the second magnet 17 when moving in the second slide groove 15, so that the second magnet 17 can better follow the synchronous movement of the first magnet 162.

[0044] The pneumatic component 5 includes a bottom shell 51, on which a guide cylinder 52 is arranged, on the inner wall of the guide cylinder 52, guide grooves 53 are symmetrically arranged, and a guide plate 54 is arranged in the guide cylinder 52. One end of the bottom shell 51 is connected to the mounting shell 4, and the guide cylinder 52 is arranged at the end of the bottom shell 51 away from the mounting shell 4. The guide groove 53 consists of two rotation grooves and two reset grooves, and the rotation grooves and the reset grooves are alternately arranged at intervals. The guide plate 54 is slidably arranged in the guide cylinder 52, and guide shafts are symmetrically arranged on the outer side of the guide plate 54.

[0045] The guide cylinder 52 is provided with an air cylinder 55, and an air plate 56 is slidably provided in the air cylinder 55. An air groove 561 is opened in the middle area of ​​the air plate 56, and a conveying shaft 57 is rotatably connected to the air plate 56.

The air groove 561 runs through the air plate 56, and one end of the conveying shaft 57 is engaged and rotatably arranged in the air groove 561. A conveying groove is opened through the axis of the conveying shaft 57, and the end of the conveying shaft 57 away from the air plate 56 extends into the air cavity, and the end of the conveying shaft 57 away from the air plate 56 is engaged and slidably connected with the air shaft 16, the conveying groove is communicated with the inside of the air cavity, and the guide plate 54 is fixedly connected to the middle area of ​​the conveying shaft 57.

[0046] An opening and closing plate 562 is symmetrically arranged inside the air plate 56. At one end of the two opening and closing plates 562 away from each other, a trigger plate 563 is hinged. At one end of the two opening and closing plates 562 away from each other, a telescopic block 564 is arranged. Pressing blocks 565 are symmetrically arranged on the air plate 56. An opening and closing groove is formed inside the air plate 56. The opening and closing plate 562 is slidably arranged in the opening and closing groove. At one end of the two opening and closing plates 562 away from each other, a third elastic sheet is arranged. One end of the third elastic sheet away from the opening and closing plate 562 is connected to the groove wall of the opening and closing groove. A hinge shaft is arranged inside the opening and closing groove. A key groove is arranged in the middle area of the trigger plate 563. The hinge shaft is slidably arranged in the key groove. An elastic force groove is formed on the opening and closing plate 562. The telescopic block 564 is slidably arranged in the elastic force groove. The bottom of the elastic force groove is connected with a first elastic sheet. One end of the first elastic sheet away from the elastic force groove is connected to the telescopic block 564. A pressing groove is formed on the air plate 56. The pressing block 565 is slidably arranged in the pressing groove. The pressing groove can correspond to the position of the elastic force groove, and the telescopic block 564 can be inserted into the pressing groove.

[0047] The jet component 2 includes a jet box 21. Pressurizing plates 22 are symmetrically arranged inside the jet box 21. Jet grooves 23 are symmetrically arranged on one side of the jet box 21. Guide strips 24 are symmetrically arranged outside the jet box 21. The pressurizing plates 22 can be slidably arranged inside the jet box 21. Guide rods are arranged in an array at one end of the two pressurizing plates 22 away from each other. One end of the guide rod away from the pressurizing plate 22 penetrates through the jet box 21. A second spring is sleeved outside the guide rod. The second spring is located inside the jet box 21. The guide strip 24 is arranged at the area position of the jet groove 23.

[0048] Synchronization shafts 25 are symmetrically arranged inside the jet box 21. Synchronization rods 26 are obliquely symmetrically arranged on the synchronization shafts 25. Sliders 27 are hinged on the synchronization rods 26. Synchronization grooves 28 are symmetrically formed on one side of the two pressurizing plates 22 close to each other. The synchronization shafts 25 are rotationally connected to the jet box 21. The synchronization rods 26 are fixedly connected to the synchronization shafts 25. The sliders 27 are arranged at one end of the synchronization rods 26 away from the synchronization shafts 25, and the sliders 27 are snap-fitted and slidably arranged in the synchronization grooves 28.

[0049] During the use process, first, the filter bag 1 is inserted into the equipment, then the installation shell 4 is connected to the equipment, and then the air pump is started. The air pump will deliver gas into the air cylinder 55, causing the gas pressure in the air cylinder 55 to increase.

[0050] Initially, the two opening and closing plates 562 are attached to each other, so that the port at one end of the conveying groove is blocked. As the gas pressure in the air cylinder 55 continuously increases, the air plate 56 moves towards the direction of the guide cylinder 52 under the action of the air pressure.

[0051] During the downward movement of the air plate 56, the guide plate 54 will move synchronously with the conveying shaft 57. At this time, the guide shaft will slide within the guide groove 53, and then the guide plate 54 will drive the conveying shaft 57 to rotate, causing the first spring to deform. When the guide plate 54 moves to the extreme position, the guide plate 54 will reset under the elastic force of the first spring, and then the air plate 56 will reset, and the first spring will reset;

[0052] When the conveying shaft 57 drives the air plate 56 to move to the extreme position towards the direction of the guide cylinder 52, the trigger plate 563 will contact the inner wall of the lower end of the air cylinder 55. Then, the included angle between the trigger plate 563 and the opening and closing plate 562 will further decrease. The two opening and closing plates 562 will be pulled by the trigger plate 563, and then the two opening and closing plates 562 will move away from each other, causing the third elastic piece to deform. At the same time, the telescopic block 564 will extend out of the elastic force groove under the elastic force of the first elastic piece, and at the same time, the telescopic block 564 will enter the downward pressure groove. At this time, the downward pressure block 565 in the downward pressure groove will extend out of the downward pressure groove. At this time, the air plate 56 will gradually rise and reset, and the gas in the air cylinder 55 can enter the conveying groove, and then enter the air cavity through the conveying groove. The gas entering the air cavity will finally enter the jet box 21 through the air outlet pipe;

[0053] When the conveying shaft 57 drives the air plate 56 to gradually reset to the initial position, at this time, the downward pressure block 565 will contact the inner wall of the upper end of the air cylinder 55, and then the downward pressure block 565 will re-enter the downward pressure groove. The telescopic block 564 in the downward pressure groove will be pushed out of the downward pressure groove, and then the two opening and closing plates 562 will approach and fit with each other under the elastic force of the third elastic piece. At this time, the gas in the air cylinder 55 cannot enter the conveying groove, resulting in the air pressure in the air cylinder 55 increasing again, and the air plate 56 starts to move towards the direction of the guide cylinder 52;

[0054] When the gas in the air cylinder 55 enters the jet box 21, the gas pressure in the jet box 21 continuously increases, causing the distance between the two pressure increasing plates 22 to gradually increase under the action of the gas pressure. And during the movement of the pressure increasing plate 22, the movement of the pressure increasing plate 22 will cause the slider 27 to slide within the synchronous groove 28, and then one synchronous rod 26 will drive the synchronous shaft 25 to rotate, causing the other synchronous rod 26 to synchronously deflect. Then, the slider 27 on the other synchronous rod 26 will slide within the synchronous groove 28 on the other pressure increasing plate 22, so that when the distance between the two pressure increasing plates 22 increases, the displacement amounts of the two pressure increasing plates 22 are equal;

[0055] When the two pressure increasing plates 22 gradually move away from each other, the second spring deforms. When the pressure increasing plate 22 gradually moves past the jet groove 23, the gas in the jet box 21 will enter the guide strip 24 through the jet groove 23. Then, the gas will be ejected towards the middle area of the two guide grooves 53 under the guiding action of the guide strip 24, and the gas will be sprayed onto the filter bag 1;

[0056] During the rotation of the conveying shaft 57, the air shaft 16 will be driven to rotate. During the rotation of the air shaft 16, the first magnetic block 162 will be driven by the support rod 161, so that the first magnetic block 162 slides in the first chute 14. During the sliding process of the first magnetic block 162, the first magnetic block 162 and the second magnetic block 17 will move synchronously under the action of magnetic force, causing the second magnetic block 17 to slide in the second chute 15. Then, when the gas in the jet box 21 is sprayed onto the filter bag 1, the dust blown off from the filter bag 1 will be collected in the collection box 3.

[0057] Embodiment 2

[0058] Refer to Figure 1-9 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that:

[0059] A toothed ring 121 is provided on the upper ring 12. A cleaning groove 31 is provided in the collection box 3. A discharge cavity 32 is provided in the collection box 3. Limiting plates 33 are symmetrically provided in the cleaning groove 31. A cleaning roller 34 is rotatably provided in the cleaning groove 31. The cleaning roller 34 is arranged between the two limiting plates 33. A first gear 35 is coaxially connected to the cleaning roller 34. The toothed ring 121 is arranged on the outer side of the upper ring 12. The cleaning groove 31 is internally communicated with the discharge cavity 32. A brush is provided on the surface of the cleaning roller 34, and the brush can contact the outer surface of the filter bag 1. The first gear 35 can be engaged with the toothed ring 121.

[0060] During use, when the second magnetic block 17 slides in the chute, the collection box 3 moves synchronously with the second magnetic block 17. At this time, the first gear 35 rotates under the action of the toothed ring 121, causing the cleaning roller 34 to rotate. Since the gas in the jet box 21 needs to be ejected when the two pressure-increasing plates 22 are separated to an appropriate position, in both cases where the gas in the jet box 21 is ejected or not ejected, the cleaning roller 34 will rotate and brush the dust on the surface of the filter bag 1 through the cleaning brush. Part of the brushed dust will be collected in the cleaning groove 31 under the action of the limiting plates 33, and then naturally settle into the ejection cavity.

[0061] The remaining structures are the same as those in Embodiment 1.

[0062] Embodiment 3

[0063] Refer to Figure 1-10 , which is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that:

[0064] A conveying screw 36 is rotatably provided in the discharge cavity 32. A second gear 37 is coaxially connected to the conveying screw 36. A discharge groove 38 is provided at one end of the collection box 3 away from the cleaning groove 31. The second gear 37 is engaged with the first gear 35. The discharge groove 38 is internally communicated with the discharge cavity 32, and one end of the collection box 3 away from the second magnetic block 17 is attached to the inner side wall of the installation shell 4.

[0065] The mounting shell 4 is symmetrically provided with movable slots 41, and mounting slots 42 are arranged in the movable slots 41. A movable plate 43 is snap-fitted and slidably arranged in the movable slots 41. One end of the movable plate 43 is snap-fitted and slidably provided with a movable block 44. A relief slot 45 is formed in the movable slot 41. The mounting slot 42 is arranged on one side of the movable slot 41 and penetrates through the mounting shell 4. A second elastic piece is arranged at one end of the movable slot 41 away from the mounting slot 42. One end of the second elastic piece close to the mounting slot 42 is connected to the movable plate 43. The movable block 44 is arranged at the end of the movable plate 43 away from the second elastic piece, and chamfer structures are symmetrically arranged on one side of the movable block 44 away from the second elastic piece. The relief slot 45 is arranged on one side of the movable slot 41 away from the mounting slot 42, and the movable block 44 can enter the relief slot 45.

[0066] During the use process, when the first gear 35 rotates, the first gear 35 will drive the second gear 37 to rotate. The rotation of the second gear 37 will drive the conveying screw 36 to rotate. The dust that has fallen into the discharge cavity 32 will be transported to the area position of the discharge slot 38 under the rotation action of the conveying screw 36. During the rotation of the collection box 3, the inner wall of the mounting shell 4 will block the discharge slot 38.

[0067] Initially, the movable plate 43 blocks the mounting slot 42 under the elastic force of the second elastic piece. When the collection box 3 rotates to contact the movable block 44, the collection box 3 will drive the movable plate 43 to move through the movable block 44. At this time, the second elastic piece deforms, and then the discharge port will coincide with the mounting slot 42.

[0068] When the collection box 3 moves again, the collection box 3 will drive the movable plate 43 to continue to move, and then the movable block 44 will move into the relief slot 45. At this time, the movable block 44 will be separated from the collection box 3, and then the movable plate 43 will reset under the reset elastic force of the second elastic piece. During this process, the movable block 44 will slide out of the relief slot 45 and reset.
