Technical Field

[0001] This utility model relates to the field of baghouse dust collectors, and in particular to a baghouse dust collector that is easy to maintain. Background Technology

[0002] A baghouse dust collector is a highly efficient and widely used dry dust collection device that separates dust from gas by filtering dust-laden gas through filter bags. A baghouse dust collector mainly consists of a housing, filter bags, an inlet, an outlet, and a dust hopper. During operation, dust-laden gas enters the housing through the inlet and is filtered by the filter bags. Dust is discharged through the dust hopper, and the filtered gas is discharged from the outlet.

[0003] In existing baghouse dust collectors, the filter bags are fixedly installed inside the housing using screws. However, this method requires the use of multiple screws for both installation and removal of the filter bags, making the process extremely complex and time-consuming. It fails to achieve the goal of quick assembly and disassembly, hinders convenient maintenance, and is therefore inconvenient to operate. Utility Model Content

[0004] The main objective of this invention is to provide a bag filter that is easy to maintain, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A baghouse dust collector that is easy to maintain includes a dust collection chamber, a dust hopper fixed at the lower end of the dust collection chamber, an installation bracket inside the dust collection chamber, and a filter bag inside the dust collection chamber. The lower end of the filter bag is provided with an installation structure connected to the installation bracket. An air storage tank is provided on the outer wall of the dust collection chamber, and a solenoid valve is connected to the air storage tank.

[0006] Preferably, the dust collection chamber has an air inlet on its side and an exhaust outlet on its top.

Detailed Implementation

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figures 1-4 As shown, a baghouse dust collector for easy maintenance includes a dust collection chamber 1, with a dust hopper 2 fixed to its lower end. An installation bracket 3 is provided inside the dust collection chamber 1, and filter bags 4 are installed inside the chamber. The lower end of each filter bag 4 is connected to an installation structure 5 on the installation bracket 3. An air storage tank 6 is located on the outer wall of the dust collection chamber 1, and a solenoid valve 7 is connected to the air storage tank 6. An air inlet 8 is provided on the side of the dust collection chamber 1, and an exhaust port 9 is provided on the top of the dust collection chamber 1. Support legs 10 are provided at the connection point between the outer wall of the dust collection chamber 1 and the dust hopper 2, and an inspection door 11 is installed on the dust collection chamber 1. A snap-fit ​​plate is provided inside the dust collection chamber 1, and the upper end of each filter bag 4 is snapped onto the snap-fit ​​plate.

[0016] When using a baghouse dust collector, the entire device is placed on support legs 10 and connected to pipelines. During operation, dust-laden gas enters the dust collection chamber 1 through the inlet 8. After being filtered by the filter bags 4, the gas is discharged from the outlet 9, while dust adheres to the filter bags 4. Some dust falls into the ash hopper 2 and is eventually discharged from the bottom of the ash hopper 2. After using the dust collector for a period of time, the solenoid valve 7 is activated, and gas from the storage tank 6 is blown into the dust collection chamber 1 in a pulsed manner to clean the filter bags 4, ensuring their normal operation. When maintenance is required, for the maintenance of filter bag 4, after opening the maintenance door 11, the mounting structure 5 at the lower end of filter bag 4 can be operated to quickly remove filter bag 4 for maintenance and replacement, making the maintenance of dust collector convenient and quick. After maintenance and replacement are completed, filter bag 4 is placed inside dust collection chamber 1 and fixed by using mounting structure 5 in conjunction with mounting bracket 3. The structure is simple and the operation is convenient and quick.

[0017] According to the above implementation scheme, the installation structure 5 includes a connecting rod 501, a screw 502, a fixing plate 503, a guide rod 504, an abutment plate 505, and an abutment spring 506. The connecting rod 501 and the screw 502 are fixedly connected, and the connecting rod 501 is installed at the lower end of the filter bag 4. The fixing plate 503 is fixed on the connecting rod 501. The guide rod 504 and the abutment plate 505 are connected, and the guide rod 504 passes through the fixing plate 503. A limiting block is provided at the upper end of the guide rod 504. A round hole is provided at the middle position of the abutment plate 505. The abutment spring 506 is sleeved on the guide rod 504, and the abutment spring 506 is located between the fixing plate 503 and the abutment plate 505. The mounting structure 5 also includes a first locking block 507 and a second locking block 508. The first locking block 507 is threadedly connected to the screw 502 and has a hexagonal block on it. The first locking block 507 is located above the mounting bracket 3. The second locking block 508 is threadedly connected to the screw 502 and is located below the mounting bracket 3.

[0018] When installing the filter bag 4 using the mounting structure 5, after pressing the abutment plate 505, the abutment plate 505 moves towards the fixing plate 503 via the guide rod 504, compressing the abutment spring 506. Then, the filter bag 4 is moved into the dust collection chamber 1 along the mounting bracket 3. The screw 502 at the lower end of the connecting rod 501 is located in the gap on the mounting bracket 3. After connecting the upper end of the filter bag 4 to the snap-fit ​​plate, the abutment plate 505 is released. Under the action of the abutment spring 506, the abutment plate 505 abuts against the mounting bracket 503. A pre-fixed effect is formed on the bracket 3. Then, the first locking block 507 is rotated to rotate and abut against the upper end of the mounting bracket 3. During this process, due to the setting of the round hole on the abutment plate 505, the abutment plate 505 and the first locking block 507 will not interfere with each other. After the first locking block 507 is locked, the second locking block 508 is rotated to rotate and abut against the lower end of the mounting bracket 3, thereby fixing the mounting structure 5 and completing the installation of the filter bag 4.

[0019] During use, due to the action of the abutment spring 506, the abutment plate 505 forms an elastic clamping force, which can increase the locking stability and prevent the locking block from loosening. When disassembly is required, rotate the first locking block 507 and the second locking block 508 to make room, then move the filter bag 4 down to remove it from the snap-fit ​​plate, and then remove the filter bag 4 to proceed with the operation.

[0020] It should be noted that the mounting bracket 3, used in conjunction with the mounting structure 5, features a screw 502 at the lower end of the connecting rod 501 in the mounting structure 5. This screw, along with the first locking block 507 and the second locking block 508, allows for quick locking and fixing of the mounting structure 5 and the mounting bracket 3, enabling rapid installation and fixing of the filter bag 4. Simultaneously, it allows for quick disassembly, facilitating maintenance of the baghouse dust collector. A fixing plate 503 is mounted on the connecting rod 501, with a guide rod 504 and an abutment plate 505 on it, working in conjunction with an abutment spring 506. During the installation of the filter bag 4, the abutment spring 506 applies an elastic force, causing the abutment plate 505 to contact the mounting bracket 3 for pre-fixation. This ensures the filter bag 4 has good stability before final installation and locking, guaranteeing installation accuracy. Furthermore, the elasticity of the abutment spring 506 provides an elastic clamping effect, preventing the locking blocks from loosening during operation and ensuring operational stability.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
