Description

These gases mainly include carbon dioxide, carbon disulfide, hydrogen sulfide, fluorides, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid, smoke dust and production line dust. These waste gases not only pollute the air, but also may enter the human body through respiration, causing harm to health. The filter cartridge dust collector is a dust collector that uses a filter cartridge as a filter element and adopts pulse blowing for reverse cleaning. After the dust-containing gas enters the filter chamber of the dust collector, part of the particles with a larger particle size in the airflow settle downward, and the particles with a smaller particle size and lighter weight in the airflow are adsorbed to the filter material surface of the outer wall of the filter cartridge in Brownian diffusion.

[0065] Further, the inside of the limiting outer cylinder 61 is obliquely provided with a dust shaking inner cylinder 70, a plurality of groups of dust discharging holes are uniformly distributed on the dust shaking inner cylinder 70, the other end of the air supply tank 90 is connected through a pulse control valve 91 and a second air supply pipe 65 (two groups of pulse control valves 91 are opened and closed according to different needs), the second air supply pipe 65 extends downward through the baffle 64 and enters the inner cylinder cavity 77 of the dust shaking inner cylinder 70, the end of the second air supply pipe 65 is provided with a second pulse nozzle 79 acting on the drawer filter cartridge 15, as shown in Figure 11 and 12 .

[0066] Further, both ends of the dust shaking inner cylinder 70 are fixed through a second bearing seat 71 and the inner wall of the limiting outer cylinder 61, an intermediate gear wheel 72 is sleeved on the outer side of the middle part of the dust shaking inner cylinder 70, an intermediate pinion 73 is meshingly arranged at the upper end of the intermediate gear wheel 72, the intermediate pinion 73 is sleeved on the output shaft of a constant speed motor 74, a motor seat 97 is communicated and arranged on the outer side of the limiting outer cylinder 61, the intermediate pinion 73 is located inside the motor seat 97, the constant speed motor 74 is arranged through the outer side of the motor seat 97, as shown in Figure 2 , 11 and 12.

[0067] Further, a feeding port 75 is formed at the right position of the upper end of the dust shaking inner cylinder 70, the feeding port 75 is communicated with the discharging channel 60, a material taking port 76 is formed at the left position of the upper end of the dust shaking inner cylinder 70, a plurality of groups of air bag spiral ribs 78 (similar to the spiral blade structure of the spiral feeder) are uniformly distributed on the cavity of the inner cylinder cavity 77 at the middle position of the dust shaking inner cylinder 70, the air bag spiral rib 78 is made of elastic air bag material and has a deformation reset capability, which can play a buffering protection role for the drawer filter cartridge 15, the drawer filter cartridge 15 is in contact with the air bag spiral rib 78 during the movement in the inner cylinder cavity 77, as shown in Figure 11 and 12 .

[0068] Further, the dust removal box 1 and the base 7 are connected through a supporting leg 98, as shown in Figure 1 .

[0069] When this embodiment is in use, smoke (or exhaust gas) is injected into the smoke chamber 11 from the air inlet 10, and flows into the interior of the dust removal box 1 through the perforated partition 12, contacts the filter elements 20 of several groups of drawer-type filter cartridges 15, and the dust therein is intercepted by the filter material. Then, the clean gas flows into the collection chamber 95 through the air flow holes 35. Under the suction force of the suction fan 5, the clean gas passes through the inside of the elbow 3 and the fan base 4 in turn, and is finally discharged to the outside from the purified gas exhaust pipe 6 (possibly transferred to external gas treatment equipment).

[0070] 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 spray pipe group 93, and is sprayed out from several groups of No. 1 pulse nozzles 94. The high-pressure airflow enters the interior of the filter element 20 through the air flow hole 35, and each group of drawer-type filter cartridges 15 is sprayed and cleaned. Finally, the dust on the drawer-type filter cartridges 15 is concentrated by settling downward and collected by the ash hopper 8.

[0071] When the drawer-type filter cartridge 15 needs to be disassembled, the first servo motor 41 is started first, and the rotating seat 42 is driven to rotate one circle through the driving shaft. During the process of the rotating seat 42 rotating one circle, the driving column 45 makes a circular motion, enters the bar-shaped motion groove 38 of the crank disk 37 and moves. The two generate a relative 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, causing the plug part 33 to rotate a certain angle, so that the connecting hook 24 originally in the curved slot 36 is unhooked due to the action of the radial rotation force, and the two groups of connecting hooks 24 are untied.

[0072] At this time, the second servo motor 51 is started, driving the small gear 50 to rotate clockwise, and the large gear 29 is decelerated and rotated counterclockwise through meshing, thereby causing the driving gear 28 coaxial with the large gear 29 to rotate counterclockwise. The driving gear 28 and the rack rod 23 interact with each other, causing the rack rod 23 to move linearly, thereby causing the entire drawer-type filter cartridge 15 to tilt along the limiting barrel groove 13 toward the drawer opening 96 (the two sets of connecting hooks 24 and the plug part 33 separate during the movement), until it disengages from the driving gear 28 and slides downward from the drawer opening 96 into the discharge channel 60 (the installation principle of the drawer-type filter cartridge 15 is the same as above and will not be repeated).

[0073] When the second servo motor 51 is working, the small sprocket 53 thereon rotates clockwise, and is pulled by the chain 56, causing the large sprocket 55 to decelerate, driving the flip part 58 to slowly flip upward (the sealing shaft 54 ​​rotates clockwise around the two sets of first bearing seats 57), so that the sealing door 59 that originally sealed the drawer opening 96 slowly opens upward, ensuring that the drawer-type filter cartridge 15 can be discharged smoothly.

[0074] The drawer-type filter cartridge 15 is guided by the discharge channel 60 and tilted from the feed port 75 to enter the inner cylinder cavity 77 of the dust-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 through meshing, driving the dust-shaking inner cylinder 70 to rotate inside the limit 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 airbag during the contact process intensifies the vibration of the drawer-type filter cartridge 15, ensuring 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 dust-shaking inner cylinder 70 through the No. 2 pulse nozzle 79. The movement of the drawer-type filter cartridge 15 is used to realize the dust cleaning operation, and the dust falls downward into the inside of the dust 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. Example 2

[0075] 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 Figures 13-14 shown.

[0076] Specifically, a dust collecting pipe 80 is provided extending from the outside of the dust collecting box 1 to the upper end of the base 7. Figure 13 shown.

[0077] The upper end of the dust collecting main pipe 80 is connected to a first sealed branch pipe 81, which extends upward into the interior of the dust discharge pipe 9, and the two are sealed and connected. Figure 13 shown.

[0078] The left end of the dust collecting main pipe 80 is connected to a second sealed branch pipe 82, which extends horizontally into the dust receiving support 62. Figure 13 shown.

[0079] Specifically, a curved ash receiving groove 83 is provided in the ash receiving support 62. The dust at the bottom of the curved ash receiving groove 83 is easy to clump and difficult to clean. A cleaning dust collection pipe 85 is provided at the lower position of the curved ash receiving groove 83 for horizontal rotation. The cleaning dust collection 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 collection pipe 85 is connected to the groove wall of the curved ash receiving groove 83 through a third bearing seat 86.Figure 14 shown.

[0080] Among them, the cleaning dust suction pipe 85 is provided with a shaft portion extending to the interior of the dust receiving support 62, and the shaft portion is connected to a cleaning motor 87 through a coupling. The cleaning motor 87 is provided through the outer side surface of the dust receiving support 62. Figure 14 shown.

[0081] Among them, a plurality of cleaning hair balls 88 are evenly distributed on the outer tube surface of the cleaning dust collection pipe 85. The cleaning hair balls 88 contact the bottom of the curved dust receiving groove 83 during the circular motion. A plurality of dust collection holes 89 are opened in the interior of the cleaning dust collection pipe 85. Figure 14 shown.

[0082] Furthermore, the cleaning dust suction pipe 85 rotates around the second sealed branch pipe 82 , and a dust suction motor is installed on the dust suction main pipe 80 .

[0083] When the present embodiment is in use, when it is necessary to clean the stored dust, the dust suction motor is turned on, the dust discharge valve is opened first, the dust accumulated in the ash receiving hopper 8 is sucked by the first sealed branch pipe 81, and discharged outwardly through the dust suction main pipe 80, and at the same time, the cleaning motor 87 is turned on to drive the cleaning dust suction pipe 85 to rotate around the second sealed branch pipe 82. During the rotation of the cleaning dust suction pipe 85, several groups of cleaning hair balls 88 on the surface make circular motions, cleaning and scraping the dust accumulated at the bottom of the curved ash receiving groove 83, causing it to be lifted up, and the cleaning dust suction pipe 85 absorbs the dust in time through several groups of dust suction holes 89, and the dust is discharged outwardly through the second sealed branch pipe 82 and the dust suction main pipe 80 in turn, thereby achieving the purpose of sealed transfer.
