[0002] Baghouse dust collectors are a type of dust removal equipment commonly used in industrial fields, primarily for collecting tiny solid particles from the air. They work by using filter bags to filter the airflow, capturing dust particles and thus purifying the air. Baghouse dust collectors play a vital role in modern industrial production, particularly in controlling dust emissions and protecting the environment.

[0003] Patent document CN221412520U discloses a baghouse dust collector, mainly comprising: a dust collection chamber; a cover plate that covers the dust collection chamber; a disassembly assembly for quick disassembly of the cover plate, the disassembly assembly including: two sets of slide rails fixedly installed on the dust collection chamber, the slide rails having grooves; a slider that slides within the grooves; and two sets of connecting blocks connected with bolts; wherein: the slider is adapted to move along the straight direction of the grooves to move the cover plate to one side of the dust collection chamber, thereby opening the upper end of the dust collection chamber. This application discloses a baghouse dust collector that, through the cooperative use of slide rails and connecting blocks, and the constraint of the slider, simplifies the cover plate installation process when replacing dust bags, saving installation time.

[0004] However, existing baghouse dust collectors require the filter bags to be disassembled and replaced one by one during use. The operation is cumbersome and it is difficult to replace multiple sets of filter bags as a whole, which leads to longer equipment downtime and reduced filter bag replacement efficiency.

[0016] (III) Beneficial Effects

[0017] This utility model provides a bag filter dust collector, which has the following beneficial effects:

[0018] 1. This baghouse dust collector, through the setting of the lifting component, when the filter bags need to be replaced, the hydraulic lifting rod is activated, which moves the sealing cover upward. The sealing cover then moves the moving plate, causing the insert plate and filter bags to be completely pulled out of the housing. Then, the pin is pulled to release the lock between the insert plate and the moving plate, and the insert plate is pulled out. Another set of insert plates with replaced filter bags is inserted into the moving plate and locked again using the pin. The hydraulic lifting rod is then activated to insert the moving plate and sealing cover back into the housing. This achieves the effect of replacing multiple sets of filter bags at once, avoiding the tedious operation of disassembling and replacing filter bags one by one. Replacement only requires overall replacement, greatly shortening the equipment downtime cycle and significantly improving the filter bag replacement efficiency.

[0019] 2. This baghouse dust collector, through the setting of the support assembly, when in use, the hydraulic lifting rod pushes the sealing cover downward to close, so that the sealing frame is locked into the slot at the top of the box. Then, the sealing frame squeezes the support spring in the opposite direction, and the positioning rod keeps the movement of the sealing frame stable. This causes the support spring to deform under force and generate elastic force, pushing the sealing frame in the opposite direction, keeping the sealing frame always tightly attached to the top of the box, thereby achieving a dynamic sealing effect, ensuring that the sealing surface is continuously in contact, and compensating for minor gaps caused by temperature changes or mechanical vibration.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1 to 4 This utility model provides a technical solution: a bag filter dust collector, including a housing 1, a movable plate 2 slidably connected inside the housing 1, an insert plate 8 inserted into the bottom of the movable plate 2, and several sets of support frames 9 fixedly connected to the bottom of the insert plate 8. The support frames 9 support filter bags 10. Filter bags 10 are fitted onto the surface of the support frames 9, and a fastening ring 11 is fixedly connected to the top of the filter bags 10. The fastening ring 11 facilitates securing the filter bags 10 onto the support frames 9. Two sets of connecting rods 3 are fixedly connected to the top of the movable plate 2, and a sealing cover 4 is fixedly connected to the top of the connecting rods 3. A lifting assembly 5 is fixedly connected to the top of the sealing cover 4. The lifting assembly 5 allows for the replacement of multiple sets of filter bags at once. The effect of 10 avoids the tedious operation of disassembling and replacing filter bags 10 one by one. When replacing, only the whole bag needs to be replaced, which greatly shortens the equipment downtime cycle and significantly improves the replacement efficiency of filter bags 10. Several sets of support components 6 are fixedly connected to the bottom of the sealing cover 4. Through the setting of support components 6, a dynamic sealing effect is achieved, ensuring that the sealing surface is continuously in contact and compensating for the small gaps caused by temperature changes or mechanical vibration. A sealing frame 7 is fixedly connected to the bottom of the support components 6. The lifting component 5 includes two hydraulic lifting rods 501 fixedly connected to the top of the sealing cover 4 on both sides. A top plate 502 is sleeved on the surface of the hydraulic lifting rods 501. The support component 6 includes a support spring 601 fixedly connected to the bottom of the sealing cover 4. A positioning rod 602 is sleeved inside the support spring 601.

[0027] Both the insert plate 8 and the movable plate 2 have several sets of through holes on their surfaces, and four sets of positioning holes on their surfaces. Pins 12 are inserted into the positioning holes, and the pins 12 are used to limit the position of the insert plate 8.

[0028] Two sets of support plates 13 are fixedly installed on both sides of the top plate 502 by bolts. The support plates 13 are fixedly installed on the top of the box body 1, and the support plates 13 serve to support the top plate 502.

[0029] A pulse air valve 14 is provided on one side of the housing 1, and a slot adapted to the sealing frame 7 is provided on the top of the housing 1. The slot facilitates the sealing frame 7 to be inserted into the sealing mechanism.

[0030] A base frame 15 is fixedly connected to the bottom of the housing 1. An air inlet pipe 16 is connected to the left side of the housing 1. One end of the air inlet pipe 16 is connected to a fan 17. The fan 17 drives the flow of exhaust gas.

[0031] The right side of the housing 1 is connected to an exhaust pipe 18, and one end of the exhaust pipe 18 is connected to a discharge chamber 19. The discharge chamber 19 facilitates the discharge of the treated gas.

[0032] In this invention, the working steps of the device are as follows:

[0033] First step: When the filter bag 10 needs to be replaced, start the hydraulic lifting rod 501, so that the hydraulic lifting rod 501 drives the sealing cover 4 upward, and then the sealing cover 4 drives the moving plate 2, so that the insert plate 8 drives the filter bag 10 to be completely pulled out from the box 1. Then pull the pin 12 to release the lock between the insert plate 8 and the moving plate 2, and then pull out the insert plate 8. Insert another set of insert plates 8 with the filter bag 10 replaced into the moving plate 2 as a whole, and use the pin 12 to lock it again. Then start the hydraulic lifting rod 501 to insert the moving plate 2 and the sealing cover 4 back into the box 1.

[0034] The second step: When in use, the hydraulic lifting rod 501 pushes the sealing cover 4 downward to close it, so that the sealing frame 7 is inserted into the slot at the top of the box 1. Then, the sealing frame 7 presses the support spring 601 in the opposite direction. The positioning rod 602 keeps the movement of the sealing frame 7 stable, so that the support spring 601 is deformed by force and generates elastic force, pushing the sealing frame 7 in the opposite direction, keeping the sealing frame 7 always in close contact with the top of the box 1.
