Description

Technical Field

[0001] This utility model relates to the technical field of baghouse dust collectors, specifically to an anti-clogging mechanism for baghouse dust collectors. Background Technology

[0002] Baghouse dust collectors are widely used dry dust filtration devices suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When dust-laden gas enters the baghouse dust collector, large and heavy dust particles settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter media, the dust is trapped, thus purifying the gas.

[0003] However, the existing anti-clogging mechanism of baghouse dust collectors usually achieves the effect of cleaning and preventing clogging by injecting compressed air into the inside of the bag. However, as the injected air weakens, the airflow decreases, resulting in incomplete cleaning of the area below the middle. Over time, this leads to the formation of a hardened ash layer, which blocks the pores of the bag and reduces the filtration efficiency. Utility Model Content

[0004] This utility model provides an anti-clogging mechanism for a bag filter dust collector, which can not only control the continuous force-accumulating impact of the filter bag to achieve the effect of vibration, but also continuously beat the filter bag to achieve the beneficial effect of efficient dust removal, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: an anti-clogging mechanism for a bag filter dust collector, including a dust collection box, two partitions fixedly connected inside the dust collection box, a matching vibrating plate arranged between the two partitions, four filter bags threadedly connected inside the vibrating plate, a vibration mechanism for controlling the vibrating plate to perform force-accumulating impact on both sides of the vibrating plate, and a linkage mechanism for beating the filter bags at the bottom of the vibrating plate.

[0006] Preferably, the vibration mechanism includes two sliding sleeves fixedly installed inside the vibration plate. Each sliding sleeve has a sliding rod slidably connected inside it. Both ends of the sliding rod are fixedly connected to the dust collection box. Each sliding sleeve has a limiting plate at its bottom. The two limiting plates are respectively fixed to the outer surface of the sliding rod. The top of the vibration plate has two springs, which are respectively sleeved on the outer surface of the sliding rod. The vibration plate has a force storage component near the springs.

[0007] Preferably, the energy storage component includes two racks fixedly mounted on the top of the excitation plate. Each rack has an incomplete gear on an adjacent side. A first rotating shaft is fixedly connected to the center of each incomplete gear. One end of each first rotating shaft is rotatably connected to a dust collector. The other end of each first rotating shaft passes through the dust collector and extends to a first bevel gear. The first bevel gear is fixedly connected to the first rotating shaft. A second bevel gear meshes with each adjacent side of the two first bevel gears. A dual-shaft motor is installed between the two second bevel gears. The dual-shaft motor is fixedly connected to the dust collector. A protective cover is installed in the dust collector near the dual-shaft motor.

[0008] Preferably, the linkage mechanism includes a second rotating shaft disposed at the bottom of the vibrating plate, one end of the second rotating shaft being rotatably connected to the dust collection box, the other end of the second rotating shaft passing through the dust collection box and extending to the first synchronous pulley, the first synchronous pulley being fixedly connected to the second rotating shaft, the first synchronous pulley being connected to the second synchronous pulley via a synchronous belt, the second synchronous pulley being fixed to the outer surface of one of the first rotating shafts, and two rotating plates being fixedly connected to the outer surface of the second rotating shaft.

[0009] Preferably, the dust collector has an air inlet on one side, an exhaust outlet on the other side, and a dust discharge outlet at the bottom.

[0010] Preferably, a discharge wheel is rotatably installed inside the ash discharge port, and a motor is installed at one end of the discharge wheel, with the motor fixedly connected to the ash discharge port.

[0011] This utility model has the following beneficial effects: 1. Through the coordinated action of the dust collector box, partition, vibrating plate, filter bag body and vibration mechanism, the vibrating plate can be continuously controlled to rise and store energy, and then quickly descend to generate a large impact force. Under the action of inertia, the dust is peeled off from the surface of the filter bag as a whole, without obvious airflow attenuation area, which improves the dust removal effect and thus achieves the purpose of preventing filter bag blockage.

[0012] 2. Through the combined action of the dust collector, partition, vibrating plate, bag body, vibration mechanism and linkage mechanism, the bag can be continuously patted during the process of controlling the bag to rise slowly and impact downwards. This not only increases the area of ​​the bag being patted, but also allows for secondary cleaning of the loose dust on the bag surface or the fine dust in the fiber gaps, preventing the dust from re-adhering after being peeled off.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 This embodiment aims to facilitate the solution to the problem of how to effectively clean dust from the surface of cloth bags. Please refer to [link / reference]. Figures 1-3 An anti-clogging mechanism for a bag filter includes a dust collection box 1. Two partitions 2 are fixedly connected inside the dust collection box 1. A door is hinged to one side of the dust collection box 1, and a control box is installed on one side of the dust collection box 1. A matching vibrating plate 3 is arranged between the two partitions 2, and the vibrating plate 3 is tightly fitted with the partitions 2 and the dust collection box 1. Four filter bags 4 are threadedly connected inside the vibrating plate 3. The filter bags 4 can block dust in the air. Vibration mechanisms 5 are arranged on both sides of the vibrating plate 3 to control the vibrating plate 3 to perform force-accumulating impacts. The vibration mechanisms 5 can control the filter bags 4 to continuously accumulate force-accumulating impacts through the vibrating plate 3. A linkage mechanism 6 is arranged at the bottom of the vibrating plate 3 to beat the filter bags 4. The linkage mechanism 6 can beat the filter bags 4 while they are accumulating force-accumulating impacts.

[0020] The vibration mechanism 5 includes two sliding sleeves 51 fixedly installed inside the vibration plate 3. Each sliding sleeve 51 has a sliding rod 52 slidably connected inside. The sliding sleeves 51 and sliding rods 52 have a good sealing effect, effectively preventing dust from entering between them. Both ends of the sliding rods 52 are fixedly connected to the dust collection box 1. Limiting plates 53 are provided at the bottom of each sliding sleeve 51. The two limiting plates 53 are respectively fixed to the outer surface of the sliding rods 52, limiting the lifting stroke of the vibration plate 3. Two springs 54 are provided at the top of the vibration plate 3, respectively sleeved on the outer surface of the sliding rods 52. After the vibration plate 3 rises to a certain height, the springs 54 control the vibration plate 3 to slide downwards quickly to impact. Energy storage components 55 are provided near the springs 54 on the vibration plate 3. The energy storage components 55 control the vibration plate 3 to rise while squeezing the springs 54, thereby achieving the effect of energy storage.

[0021] The energy storage component 55 includes two racks 551 fixedly mounted on the top of the vibrating plate 3. Each rack 551 has an incomplete gear 552 on an adjacent side. The incomplete gear 552 continuously meshes with and disengages from the racks 551 as it rotates. A first rotating shaft 553 is fixedly connected to the center of each incomplete gear 552. One end of each first rotating shaft 553 is rotatably connected to the dust collector 1, and the other end of each first rotating shaft 553 passes through the dust collector 1 and extends to a first bevel gear 554. The first bevel gear 554 meshes with the first… A rotating shaft 553 is fixedly connected. Two first bevel gears 554 are each meshed with a second bevel gear 555 on their adjacent sides. A dual-shaft motor 556 is installed between the two second bevel gears 555. The dual-shaft motor 556 is fixedly connected to the dust collection box 1. A protective cover 557 is installed in the dust collection box 1 near the dual-shaft motor 556. The protective cover 557 can protect the first bevel gears 554 and the second bevel gears 555, preventing dust from entering between the first bevel gears 554 and the second bevel gears 555 when the device is used in a high-dust environment.

[0022] In this embodiment: a dual-axis motor 556 is driven, which simultaneously drives the second bevel gears 555 on both sides. The second bevel gears 555 drive the first rotating shaft 553 through the first bevel gear 554. While the first rotating shaft 553 rotates, it drives the incomplete gear 552. The incomplete gear 552 meshes with the rack 551 while rotating, and drives the excitation plate 3 and the bag body 4 through the rack 551. The excitation plate 3 rises on the surface of the slide rod 52 through the sliding sleeve 51, while squeezing the spring 54. When the incomplete gear 552 separates from the rack 551, the spring 54 elastically recovers, pushing the excitation plate 3 and the bag body 4 to descend rapidly, causing the excitation plate 3 to collide with the limiting plate 53, thereby generating a strong impact force on the bag body 4 and shaking off the dust on the surface of the bag body 4.

The first synchronous pulley 62 is fixedly connected to the second rotating shaft 61. The first synchronous pulley 62 is connected to a second synchronous pulley 64 via a synchronous belt 63. The diameter of the second synchronous pulley 64 is larger than that of the first synchronous pulley 62. The second synchronous pulley 64 is fixed to the outer surface of one of the first rotating shafts 553. Two rotating plates 65 are fixedly connected to the outer surface of the second rotating shaft 61. The side of the rotating plates 65 away from the second rotating shaft 61 is set as an arc shape.

[0024] The dust collector 1 has an air inlet 7 on one side and an exhaust port 8 on the other side. Air enters the interior of the device through the air inlet 7 and then passes through the filter bag body 4 to filter the dust in the air. The filtered air is discharged to the outside of the device through the exhaust port 8. The dust discharge port 9 is located at the bottom of the dust collector 1.

[0025] A discharge wheel 10 is rotatably installed inside the ash discharge port 9. A motor 11 is installed at one end of the discharge wheel 10. The motor 11 is fixedly connected to the ash discharge port 9 and can discharge the shaken-off dust from the ash discharge port 9 to the outside of the device.
