Description

Technical Field

[0001] This utility model belongs to the technical field of pulse single-unit bag dust collectors, specifically relating to a pulse single-unit bag dust collector that is easy to clean. Background Technology

[0002] Dust collectors, especially pulse jet bag filters, are widely used in various industrial and mining enterprises such as metallurgy, building materials, machinery, chemical industry, and mining due to their high-efficiency dust filtration capabilities. They are mainly used for dust removal and purification of non-fibrous industrial dust and material recovery, and are key equipment for controlling dust pollution and protecting the production environment and personnel health in industrial production.

[0003] Currently, most pulse jet baghouse dust collectors on the market employ a "pulse jet cleaning" method. This involves briefly and rapidly blowing high-pressure air into the filter bag, causing it to expand and vibrate, thus dislodging dust. Furthermore, some devices (such as the pulse jet baghouse dust collector disclosed in Chinese Patent Publication No. CN220530984U) also feature vertically movable brushes on the filter bag surface for further cleaning. However, because the brushes have a relatively simple cleaning trajectory, their effectiveness in removing stubborn dust is poor, easily leading to incomplete cleaning of the filter bag surface and consequently affecting the subsequent dust collection efficiency of the pulse jet baghouse dust collector.

[0004] Meanwhile, when discharging the dust accumulated at the bottom of the dust collector, the accumulated dust often clumps together and blocks the discharge channel, resulting in poor discharge. Utility Model Content

Detailed Implementation

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] like Figures 1 to 12As shown, a pulse jet bag filter for easy cleaning includes a housing 1. A first hollow cylinder 2 is fixedly connected to the top of the inner wall of the housing 1. A first horizontal plate 3 is fixedly connected to the bottom of the first hollow cylinder 2. A threaded hole 4 is opened inside the first horizontal plate 3. A threaded cylinder 5 is threadedly connected to the inner wall of the threaded hole 4. A filter bag 6 is adhered to the inner wall of the threaded cylinder 5. Electric push rods 7 are fixedly connected to both the left and right sides of the first hollow cylinder 2. A second hollow cylinder 8 is fixedly connected to the telescopic end of the electric push rod 7. A circular hole 9 is opened inside the second hollow cylinder 8. A cylindrical cylinder 10 is fitted into the inner wall of the circular hole 9. A toothed ring 11 is fixedly connected to the surface of the cylinder 10. The upper and lower sides of the toothed ring 11 are in contact with the inner wall of the second hollow cylinder 8. A translation bracket 12 is slidably connected to the inner wall of the second hollow cylinder 8. A rack 13 is fixedly connected to the inner wall of the translation bracket 12. The rack 13 and the toothed ring 11 mesh with each other. A vertical plate 14 is fixedly connected to the right side of the inner wall of the box 1. A corrugated hole 15 is opened inside the vertical plate 14. The inner wall of the corrugated hole 15 is slidably connected to the surface of the translation bracket 12. An annular brush 16 is fixedly connected to the inner wall of the cylinder 10. The bristles of the annular brush 16 are in contact with the surface of the filter bag 6.

[0019] The translation bracket 12 includes a second horizontal plate 121, a rectangular hole 122, a U-shaped plate 123, a cylinder 124, and a sleeve 125. The surface of the second horizontal plate 121 is slidably connected to the inner wall of the second hollow cylinder 8. The rectangular hole 122 is opened inside the second horizontal plate 121. The back of the rack 13 is fixedly connected to the inner wall of the rectangular hole 122. The left side of the U-shaped plate 123 is fixedly connected to the right side of the second horizontal plate 121. Both the front and rear ends of the cylinder 124 are fixedly connected to the inner wall of the U-shaped plate 123. The sleeve 125 is sleeved on the cylinder 124, and the surface of the sleeve 125 is slidably connected to the inner wall of the corrugated hole 15.

[0020] The right side of the box 1 is fixedly connected to the first air inlet pipe 17, the upper surface of the box 1 is fixedly connected to the air outlet pipe 18, the bottom of the box 1 is fixedly connected to the discharge pipe 19, and the bottom end of the discharge pipe 19 is fixedly connected to the discharge valve 20.

[0021] A first through hole 21 is provided on the left side of the box body 1, and a second through hole 22 is provided on both the left and right sides of the first hollow cylinder 2. A jet pipe 23 is fixedly connected to the right side of the inner wall of the box body 1, the inner wall of the first through hole 21, and the inner wall of the second through hole 22. A jet nozzle 24 is fixedly connected to the bottom of the jet pipe 23. A pulse valve 25 is fixedly connected to the left side of the box body 1. The outlet end of the pulse valve 25 is fixedly connected to the end of the jet pipe 23, and the inlet end of the pulse valve 25 is fixedly connected to the second inlet pipe 26.

[0022] It should be noted that the filter bag 6 can be fixed on the first horizontal plate 3 by the cooperation of the threaded cylinder 5 and the threaded hole 4. The air outlet pipe 18 is located above the first hollow cylinder 2, and the first air inlet pipe 17 is located below the first hollow cylinder 2. When the industrial waste gas enters the box 1 through the first air inlet pipe 17, the dust in the industrial waste gas is filtered by the filter bag 6. The filtered dust is intercepted on the surface of the filter bag 6, and the filtered industrial waste gas is discharged through the air outlet pipe 18.

[0023] The second hollow cylinder 8 is controlled to move up and down by the electric push rod 7. The second horizontal plate 121 can slide left and right inside the second hollow cylinder 8. When the second hollow cylinder 8 moves up and down, the second horizontal plate 121 can move back and forth left and right through the cooperation of the U-shaped plate 123, cylinder 124, sleeve 125, vertical plate 14 and corrugated hole 15. The cylinder 10 can rotate back and forth left and right through the cooperation of the rack 13 and toothed ring 11. At this time, the annular brush 16 can rotate back and forth left and right while moving up and down. Through the compound motion of up and down movement and rotation, the cleaning effect of the annular brush 16 on the surface of the filter bag 6 can be effectively improved, thereby avoiding the residue of stubborn dust on the filter bag 6.

[0024] The second air inlet pipe 26 is connected to the air outlet of the air pump. When cleaning the dust on the filter bag 6, the air pump and pulse valve 25 are turned on, so that the high-pressure compressed air in the air pump is injected into the filter bag 6 at a very high speed through the jet nozzle 24. After the high-pressure pulse airflow enters the filter bag 6, it will form a strong "reverse impact airflow" inside the filter bag 6, causing the filter bag 6 to expand and vibrate instantly (similar to the effect of "a balloon being inflated and then contracted instantly"). The "dust filter layer" on the surface of the filter bag 6 is quickly peeled off and broken, and then falls to the bottom of the box 1 under the action of gravity.

[0025] like Figures 1 to 13 As shown, a third hollow cylinder 27 is fixedly connected to the bottom of the box 1. A third through hole 28 is opened on the surface of the third hollow cylinder 27. A guide sleeve 29 is fixedly connected to the inner wall of the third through hole 28. A hammering mechanism 30 is fixedly connected to the surface of the third hollow cylinder 27. The surface of the hammering mechanism 30 is slidably connected to the inner wall of the guide sleeve 29.

[0026] The hammering mechanism 30 includes a spring 301, a connecting block 302, an upper hammering column 303, a lower hammering column 304, and a vibration motor 305. The two ends of the spring 301 are fixedly connected to the surface of the connecting block 302 and the surface of the third hollow cylinder 27, respectively. The upper and lower sides of the connecting block 302 are fixedly connected to the bottom end of the upper hammering column 303 and the top end of the lower hammering column 304, respectively. The side of the connecting block 302 away from the third hollow cylinder 27 is fixedly connected to the mounting surface of the vibration motor 305.

[0027] It should be noted that when the vibration motor 305 on the hammering mechanism 30 is started, the upper hammering column 303 will hammer the bottom of the box 1 and the lower hammering column 304 will hammer the discharge pipe 19 through the cooperation of the guide sleeve 29, spring 301, connecting block 302, upper hammering column 303 and lower hammering column 304. At this time, the dust accumulated in the box 1 and the discharge pipe 19 can be loosened by hammering, so that the dust accumulated in the box 1 can be quickly discharged through the discharge pipe 19.

[0028] The working principle of this utility model is as follows: when industrial waste gas enters the housing 1 through the first inlet pipe 17, the dust in the industrial waste gas is filtered through the filter bag 6. The filtered dust is intercepted on the surface of the filter bag 6, and the filtered industrial waste gas is discharged through the outlet pipe 18.

[0029] When cleaning the dust adsorbed on the surface of filter bag 6, turn on the air pump and pulse valve 25, so that the high-pressure compressed air in the air pump is injected into the filter bag 6 at a very high speed through the jet nozzle 24. After the high-pressure pulse airflow enters the filter bag 6, it will form a strong "reverse impact airflow" inside the filter bag 6, causing the filter bag 6 to expand and vibrate instantly (similar to the effect of "a balloon being inflated and then contracted instantly"). The "dust filter layer" on the surface of the filter bag 6 is quickly peeled off and broken, and then falls to the bottom of the box 1 under the action of gravity.

[0030] Meanwhile, the second hollow cylinder 8 is controlled to move up and down by the electric push rod 7. When the second hollow cylinder 8 moves up and down, the second horizontal plate 121 can move back and forth left and right through the cooperation of the U-shaped plate 123, cylinder 124, sleeve 125, vertical plate 14 and corrugated hole 15. The cylinder 10 can be rotated back and forth left and right through the cooperation of the rack 13 and toothed ring 11. At this time, the annular brush 16 can rotate back and forth left and right while moving up and down, and the surface of the filter bag 6 can be cleaned by the annular brush 16.

[0031] After cleaning is completed, turn off the air pump and pulse valve 25, and move the second hollow cylinder 8 to the designated position using the electric push rod 7.

[0032] When it is necessary to discharge the dust accumulated at the bottom of the box 1, open the discharge valve 20 and start the vibration motor 305. At this time, through the cooperation of the guide sleeve 29, spring 301, connecting block 302, upper hammer column 303 and lower hammer column 304, the upper hammer column 303 will hammer the bottom of the box 1, and the lower hammer column 304 will hammer the discharge pipe 19. Through the hammering, the dust accumulated in the box 1 and the discharge pipe 19 can be loosened, so that the dust accumulated in the box 1 can be quickly discharged through the discharge pipe 19.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
