Description

Technical Field

[0001] The present invention relates to the technical field of air pollution prevention and control, and particularly to a drawer-type quick-release filter cartridge structure. Background Art

[0002] Industrial waste gas pollution refers to the gases containing pollutants emitted by enterprises during the production process. These gases mainly include carbon dioxide, carbon disulfide, hydrogen sulfide, fluorides, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid, soot, and production line dust, etc. These waste gases not only pollute the air but may also enter the human body through breathing, causing harm to health. A filter cartridge dust collector uses filter cartridges as filtering elements and adopts pulse jetting for back cleaning. After the dust-containing gas enters the filtering chamber of the dust collector, part of the particles with larger particle sizes in the airflow settle downward, while the particles with smaller and lighter particle sizes are adsorbed on the surface of the filter material on the outer wall of the filter cartridge during Brownian diffusion. The cleaned gas after filtration enters the interior of the filter cartridge and then enters the clean gas chamber through the ventilation holes connected inside the filter cartridge, and is then discharged outside the machine body. The existing filter cartridge dust collectors have many technical defects during use. First, compared with bag dust collectors, due to the easy clogging of filter cartridges, there is a problem of high replacement and maintenance frequencies. At present, all filter cartridges are manually installed and disassembled, so the installation and disassembly processes are time-consuming and laborious, with low automation, resulting in an increase in the maintenance time and cost of the filter cartridge dust collector. Second, since a large amount of dust still remains on the surface of the replaced filter cartridges, it is easy to cause secondary pollution in the workshop, further leading to many technical drawbacks in the repair of filter cartridges and the treatment of waste filter cartridges.

[0003] In summary, considering that the existing facilities cannot meet the working requirements, for this reason, we propose a drawer-type quick-release filter cartridge structure. Summary of the Invention

[0023] The present invention provides a drawer-type quick-release filter cartridge structure through improvement. Compared with the prior art, it has the following significant improvements and advantages: During the process of the drawer-type filter cartridge moving obliquely upward, the plug head enters the interior of the filter cartridge, uses the arc chamfer to expand the two connecting hooks, makes the distance between the connecting hooks larger, and then directly inserts into the corresponding curved slot. The bottom of the curved slot blocks the hook tail, so that the drawer-type filter cartridge is automatically fixed on the rotator. Start the first servo motor to drive the rotating seat to rotate one week, the driving column makes a circular motion, enters the strip-shaped motion slot of the crank disk and moves, causing the crank disk to rotate a certain angle, making the plug head rotate a certain angle, and making the connecting hooks originally in the curved slot become unhooked due to the action of the radial turning force. The two connecting hooks are no longer restricted, achieving the purpose of automatic fixing and disassembly, saving time and effort.

[0024] Start the second servo motor. On the one hand, drive the small gear to rotate clockwise. After a series of transmissions, the driving gear rotates counterclockwise, causing the rack bar to move linearly, so that the entire drawer-type filter cartridge moves obliquely towards the drawer opening along the limiting cylinder slot, achieving the purpose of automatically exporting the drawer-type filter cartridge. On the other hand, the small sprocket rotates clockwise, and through the traction of the chain, the large sprocket is caused to decelerate, driving the flipping part to slowly flip upward and the sealing door to slowly open upward, ensuring that the drawer-type filter cartridge can be smoothly discharged, realizing the synchronization of the two movement processes, with high quick-release efficiency, high automation degree, saving the power source, and being energy-saving and environment-friendly.

[0025] Start the constant-speed motor. After a series of transmissions, it drives the ash-shaking inner cylinder to rotate inside the limit outer cylinder. The drawer-type filter cartridge is vibrated during the movement along with the inner cylinder cavity, shaking off the dust on its own filter element, and cooperating with the second pulse nozzle to achieve the purpose of automatic ash cleaning. During the movement, the drawer-type filter cartridge contacts the airbag spiral rib. On the one hand, the airbag spiral rib pushes the drawer-type filter cartridge towards the material-taking port through the spiral frictional force, achieving the purpose of automatic transportation. On the other hand, the elastic force of the airbag during the contact process intensifies the vibration degree of the drawer-type filter cartridge (and has the function of flexible protection), ensuring that the dust on the filter element is cleaned thoroughly, thus significantly improving the cleaning efficiency and having a high degree of automation.

[0026] Turn on the dust suction motor. First, use the first sealed branch pipe to suck the accumulated dust in the ash receiving hopper and output it outward through the dust suction main pipe. At the same time, turn on the cleaning motor, drive the cleaning dust suction pipe to rotate around the second sealed branch pipe, and several groups of cleaning wool balls on the surface of the cleaning dust suction pipe make circular motions to clean the dust accumulated at the bottom of the curved ash receiving trough, making it rise. The cleaning dust suction pipe timely sucks the floating dust through several groups of dust suction holes, and the floating dust is output outward through the second sealed branch pipe and the dust suction main pipe in sequence. It has the function of automatically cleaning the accumulated dust at multiple positions simultaneously, with strong sealing, avoiding secondary dust pollution in the workshop, being energy-saving and environmentally friendly, and improving the intelligent management level of the workshop.

[0051] Among them, a feeding port 75 is arranged at the upper right position of the dust shaking inner cylinder 70. The feeding port 75 is communicated with the blanking channel 60. A material taking port 76 is arranged at the upper left position of the dust shaking inner cylinder 70. A number of groups of airbag spiral ribs 78 (similar to the spiral blade structure of a spiral feeder) are evenly distributed on the inner cylinder cavity 77 in the middle position of the dust shaking inner cylinder 70. The airbag spiral ribs 78 are made of elastic airbag material and have the ability of deformation and reset, which can play a role in buffering and protecting the drawer-type filter cartridge 15. The drawer-type filter cartridge 15 contacts with the airbag spiral ribs 78 during the movement inside the inner cylinder cavity 77, as Figure 11 and 12 shown

[0052] Furthermore, the dust removal box body 1 and the base 7 are connected through a support leg 98, as Figure 1 shown

[0053] During the use of this embodiment, the flue gas (or waste gas) is injected into the dust chamber 11 from the air inlet 10 and flows through the perforated partition 12 into the interior of the dust removal box body 1, contacts the filter elements 20 of a number of groups of drawer-type filter cartridges 15, and the dust in it is intercepted by the filter material. Then the clean gas surges into the collection chamber 95 through the air flow holes 35. Under the suction of the suction fan 5, the clean gas sequentially passes through the elbow 3 and the interior of the fan seat 4, and finally is discharged to the outside from the purified gas discharge pipe 6 (possibly transferred to an external gas treatment device).

[0054] When the dust on the filter element 20 reaches a certain amount, by opening the pulse control valve 91, the high-pressure air in the air supply tank 90 enters the first air supply pipe 92, and is evenly distributed in the pulse injection pipe group 93, and is ejected from a number of first-stage pulse nozzles 94 respectively. The high-pressure air flow enters the interior of the filter element 20 through the air flow holes 35, and blows and cleans the dust on each group of draw-type filter cartridges 15. Finally, the dust on the draw-type filter cartridges 15 is collected by the ash hopper 8 through downward settlement and concentration.

[0055] When the draw-type filter cartridge 15 needs to be disassembled, first start the first servo motor 41, drive the rotating seat 42 to rotate one week through the drive shaft. During the process of the rotating seat 42 rotating one week, the driving column 45 makes a circular motion, enters the strip-shaped motion groove 38 of the crank disk 37 and moves. The two generate a relative acting force, causing the crank disk 37 to rotate a certain angle. The crank disk 37 drives the rotating roller 31 to rotate around the positioning bearing 32, so that the plug head 33 rotates a certain angle accordingly. Due to the acting force of the radial rotation force, the connecting hook 24 originally in the curved card slot 36 is disengaged, and the two groups of connecting hooks 24 are no longer restricted.

[0056] At this time, start the second servo motor 51, drive the small gear 50 to rotate clockwise, and through meshing, the large gear 29 rotates counterclockwise at a reduced speed, so that the drive gear 28 coaxial with the large gear 29 rotates counterclockwise. The drive gear 28 acts on the rack bar 23, causing the rack bar 23 to move linearly, so that the entire draw-type filter cartridge 15 moves obliquely along the limit cylinder groove 13 towards the drawer opening 96 (the two groups of connecting hooks 24 and the plug head 33 are separated during the movement), until it disengages from the drive gear 28 and slides down from the drawer opening 96 position into the blanking channel 60 (the installation principle of the draw-type filter cartridge 15 is the same as above and will not be elaborated).

[0057] When the second servo motor 51 is working, the small sprocket 53 on it rotates clockwise accordingly. Through the traction of the chain 56, the large sprocket 55 is caused to move at a reduced speed, driving the flipping part 58 to slowly flip upward (the sealing shaft 54 rotates clockwise around the two groups of first bearing seats 57), so that the sealing door 59 that originally sealed the drawer opening 96 slowly opens upward, ensuring that the draw-type filter cartridge 15 can be discharged smoothly.

[0058] The drawer-type filter cartridge 15 is guided by the feed port 75 and tilted into the inner cylinder cavity 77 of the ash-shaking inner cylinder 70. At this time, the uniform-speed motor 74 is started to drive the intermediate small gear 73 to rotate, and the intermediate large gear 72 is caused to decelerate and rotate through meshing, driving the ash-shaking inner cylinder 70 to rotate inside the limiting outer cylinder 61. The drawer-type filter cartridge 15 is vibrated in the process of moving with the inner cylinder cavity 77, and the dust on its own filter element 20 is shaken off. The drawer-type filter cartridge 15 contacts the airbag spiral rib 78 during the movement. On the one hand, the airbag spiral rib 78 pushes the drawer-type filter cartridge 15 toward the material taking port 76 through the spiral force On the one hand, the elastic force of the air bag during the contact process intensifies the vibration of the drawer-type filter cartridge 15 to ensure that the dust on the filter element 20 is cleaned, and at the same time, the pulse control valve 91 is opened, and the high-pressure air in the air supply tank 90 enters the second air supply pipe 65, and is sprayed on the drawer-type filter cartridge 15 in the ash shaking inner cylinder 70 through the No. 2 pulse nozzle 79. In conjunction with the movement of the drawer-type filter cartridge 15, the cleaning operation is realized, and the dust falls downward into the ash receiving support 62 until the drawer-type filter cartridge 15 moves to the left end of the inner cylinder cavity 77, and is taken out from the material taking port 76 by opening the material taking cover 63. Embodiment 2

[0059] On the basis of the first embodiment, the dust stored in the ash receiving support 62 and the ash receiving hopper 8 generally needs to be cleaned regularly, but manual cleaning is time-consuming and labor-intensive, and it is easy to form dust during the cleaning process, polluting the external environment. In order to solve the above technical problems, we have the following design, such as Figure 13-14 shown.

[0060] Specifically, a dust collecting pipe 80 is provided extending from the outside of the dust removal box 1 to the upper end of the base 7. Figure 13 shown.

[0061] The upper end of the dust collecting main pipe 80 is connected with a first sealed branch pipe 81, which extends upward into the interior of the dust discharging pipe 9, and the two are sealed and connected. Figure 13 shown.

[0062] The end of the dust collecting main pipe 80 is connected to the left side thereof with a second sealed branch pipe 82, which extends horizontally into the dust receiving support 62. Figure 13 shown.

[0063] Specifically, a curved ash receiving groove 83 is provided in the ash receiving support 62. The ash at the bottom of the curved ash receiving groove 83 is easy to clump and difficult to clean. A cleaning dust suction pipe 85 is provided at the lower position of the curved ash receiving groove 83 for horizontal rotation. The cleaning dust suction pipe 85 is connected to the second sealing branch pipe 82 by a sealing bearing 84 (the two are sliding seals). The other end of the cleaning dust suction pipe 85 is connected to the groove wall of the curved ash receiving groove 83 through a third bearing seat 86.Figure 14 as shown

[0064] Among them, a shaft portion extends into the interior of the ash receiving support 62 in the cleaning and dust suction pipe 85. The shaft portion is connected with a cleaning motor 87 through a coupling. The cleaning motor 87 is arranged through the outer side surface of the ash receiving support 62, as Figure 14 shown

[0065] Among them, several groups of cleaning wool balls 88 are evenly distributed on the outer pipe surface of the cleaning and dust suction pipe 85. The cleaning wool balls 88 contact the bottom of the curved ash receiving groove 83 during the circular motion. Several groups of dust suction holes 89 are opened through the interior of the cleaning and dust suction pipe 85 outward, as Figure 14 shown

[0066] Furthermore, the cleaning and dust suction pipe 85 rotates around the second sealing branch pipe 82, and a dust suction motor is installed on the main dust suction pipe 80.

[0067] When in use in this embodiment, when it is necessary to clean the stored dust, the dust suction motor is turned on. First, the ash discharge valve is opened to suck the dust accumulated in the ash receiving hopper 8 through the first sealing branch pipe 81 and output it outward through the main dust suction pipe 80. At the same time, the cleaning motor 87 is turned on to drive the cleaning and dust suction pipe 85 to rotate around the second sealing branch pipe 82. During the rotation of the cleaning and dust suction pipe 85, several groups of cleaning wool balls 88 on the surface perform circular motion to clean and scrape the dust accumulated at the bottom of the curved ash receiving groove 83, making it rise. The cleaning and dust suction pipe 85 timely sucks the floating dust through several groups of dust suction holes 89, and the floating dust is output outward through the second sealing branch pipe 82 and the main dust suction pipe 80 in sequence, achieving the purpose of sealed transfer.
