Description

Technical Field

[0001] This utility model relates to the technical field of dust removal devices, and in particular to a dust removal device with airflow uniform distribution function. Background Technology

[0002] The primary reason for requiring uniform airflow distribution in baghouse dust collectors is to ensure dust removal efficiency, extend filter bag life, and maintain stable system operation. Uneven airflow distribution can lead to excessively high or low local loads on the filter bags, causing the following problems: First, high-speed airflow areas cause frequent erosion of the dust layer on the filter bag surface, accelerating filter bag wear and shortening its lifespan; simultaneously, the filtration resistance in these areas increases sharply, leading to higher energy consumption. Second, low-speed airflow areas are prone to dust caking due to dust retention, reducing filtration efficiency and even causing bag clogging. Furthermore, uneven airflow distribution can cause the cleaning system to fail; some filter bags may accumulate excessive dust due to insufficient cleaning, while others may experience secondary dust re-entrainment due to over-cleaning. Therefore, it is necessary to distribute the airflow evenly across the baghouse to improve dust removal efficiency. Utility Model Content

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] Example 1:

[0028] like Figure 1-5As shown, a dust removal device with airflow uniform distribution function includes a box 1 with a top plate 2 installed on top. Multiple dust filter bags 8 are fixedly connected to the bottom of the top plate 2. The dust filter bags 8 and exhaust pipes 9 are arranged in an alternating manner to allow the dust filter bags 8 to filter more evenly and prevent local wear. An air inlet pipe 4 is fixedly connected to one side of the box 1. A diversion pipe 7 is fixedly connected to one end of the air inlet pipe 4. Multiple exhaust pipes 9 are fixedly connected to one side of the diversion pipe 7. Multiple exhaust slots 10 are opened on both sides of the exhaust pipes 9. The exhaust slots 10 are semi-circular. Multiple sealing plates 12 are rotatably connected to both sides of the exhaust pipes 9. The sealing plates 12 are also semi-circular. A toothed ring 11 is fixedly connected to the outside of the sealing plate 12. A toothed rod 14 is slidably connected to both sides of the exhaust pipes 9.

[0029] During use, the airflow containing particulate matter enters from the intake pipe 4, then enters multiple exhaust pipes 9 through the diversion pipe 7, and is discharged from the semi-circular exhaust slots 10 on both sides of the exhaust pipe 9. Because the exhaust pipe 9 is relatively long, the airflow from the exhaust slots 10 at both ends is uneven due to factors such as the decrease in air pressure and friction. Therefore, after a period of use, the movable rack 14 can be moved towards the end of the exhaust pipe 9. During this movement, the sealing plate 12 can be rotated 180 degrees by meshing with the gear ring 11. This can seal the exhaust slot 10 near the intake end, allowing the airflow to be discharged through the exhaust slot 10 with a lower airflow at the end, making the airflow distribution more uniform.

[0030] After the dust filter bag 8 is backflushed to remove dust, the moving toothed rod 14 moves to the air inlet side of the exhaust pipe 9 to reset. This can drive the sealing plate 12 to rotate 180 degrees in the opposite direction, opening the sealed exhaust pipe 9 and restoring the initial exhaust state.

[0031] In this embodiment, a sliding bracket 15 is fixedly connected below the rack 14, and two synchronous pulleys 16 are rotatably connected below the exhaust pipe 9. The multiple synchronous pulleys 16 are connected by a synchronous belt 17. The lower end of the sliding bracket 15 is fixedly connected to one side of the synchronous belt 17.

[0032] Multiple synchronous pulleys 16 are fixedly connected to synchronous shafts 19, and a closed motor 18 is fixedly connected below one side exhaust pipe 9. The closed motor 18 is fixedly connected to the power output end of the synchronous shaft 19.

[0033] After the closed motor 18 is started, it can drive multiple synchronous pulleys 16 to rotate, which in turn drives the synchronous belt 17 to rotate. This can drive the upper sliding bracket 15, allowing the moving gears 14 on both sides to slide simultaneously, which can simultaneously drive the closed plates 12 on both sides to close the exhaust groove 10.

[0034] In this embodiment, a lifting drive plate 20 is fixedly connected to one side of the plurality of exhaust pipes 9, a drive groove 21 is opened at one end of the lifting drive plate 20, and a lifting support frame 24 is slidably connected to both sides of the exhaust pipes 9, and the lifting support frame 24 is fixedly connected to the inner wall of the box 1.

[0035] A swing motor 6 is fixedly connected to one side of the housing 1. A connecting rod 22 is fixedly connected to the power output end of the swing motor 6. A drive wheel 23 is rotatably connected to one end of the connecting rod 22, and the other end of the drive wheel 23 is movably connected to the drive groove 21.

[0036] When the swing motor 6 rotates, it can drive the drive wheel 23 to move in a circular motion through the connecting rod 22. At this time, it can drive the lifting drive plate 20 to swing up and down through the drive groove 21. Furthermore, it can make multiple exhaust pipes 9 swing up and down, change the position of airflow discharge, and further achieve longitudinal airflow uniformity.

[0037] In this embodiment: During use, the airflow containing particulate matter enters from the intake pipe 4, then enters multiple exhaust pipes 9 through the diversion pipe 7, and is discharged from the semi-circular exhaust slots 10 on both sides of the exhaust pipe 9. Because the exhaust pipe 9 is relatively long, the airflow from the exhaust slots 10 at both ends is uneven due to factors such as the decrease in air pressure and friction. Therefore, after a period of use, the movable toothed rod 14 can be moved towards the end of the exhaust pipe 9. In this way, the closing plate 12 can be rotated 180 degrees by meshing with the toothed ring 11 during the movement. This can close the exhaust slot 10 near the intake end, allowing the airflow to be discharged through the exhaust slot 10 with a lower airflow at the end, making the airflow distribution more uniform.

[0038] After the dust filter bag 8 is backflushed and dust is removed, the moving toothed rod 14 moves to the air inlet side of the exhaust pipe 9 to reset, which can drive the sealing plate 12 to rotate 180 degrees in the opposite direction, opening the sealed exhaust pipe 9 and restoring the initial exhaust state.

[0039] After the closed motor 18 starts, it can drive multiple synchronous pulleys 16 to rotate, which in turn drives the synchronous belt 17 to rotate. This can drive the upper sliding bracket 15, allowing the moving gears 14 on both sides to slide simultaneously. This can also drive the closing plates 12 on both sides to close the exhaust slots 10. When the swing motor 6 rotates, it can drive the drive wheel 23 to move in a circular motion through the connecting rod 22. At this time, it can drive the lifting drive plate 20 to swing up and down through the drive slot 21. This can further cause multiple exhaust pipes 9 to sway up and down, changing the position of the airflow discharge and further achieving uniform longitudinal airflow distribution.

[0040] Example 2:

[0041] A dust removal device with airflow uniform distribution function is provided in this embodiment, which is improved based on embodiment 1 as follows: Figure 1-5 As shown,

[0042] In this embodiment, a top cover 3 is fixedly connected above the top plate 2, and an air outlet pipe 5 is fixedly connected above the top cover 3; the top cover 3 has a backflushing cleaning component inside, which can backflush and clean the dust filter bag 8 below, and the air outlet pipe 5 is connected to an external air pump for suction.

[0043] In this embodiment, multiple limiting rubber platforms 13 are fixedly connected to both sides of the exhaust pipe 9, and one end of the limiting rubber platform 13 is slidably connected to the outside of the gear ring 11.

[0044] The limiting rubber platform 13 can prevent the gear ring 11 from rotating through friction. This way, the gear ring 11 will only rotate when the rack 14 passes by and meshes with the gear ring 11, preventing the sealing plate 12 from shaking during use.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
