Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly filter bag technology, specifically to environmentally friendly filter bags that prevent dust. Background Technology

[0002] Filter bags possess excellent chemical stability and heat resistance, representing the highest performance in the filter media industry and the most advanced type of commonly used filter materials. They achieve high levels in filtration efficiency and precision. Filter bags are a crucial component in the operation of baghouse dust collectors. Typically, cylindrical filter bags are suspended vertically within the dust collector. The fabric and design of filter bags should strive for high-efficiency filtration, easy dust removal, and durability. Filter cloth relies on the thickness of the entire filtration layer for filtration, belonging to deep filtration.

[0003] An investigation revealed that a novel filter bag (publication number: CN218924105U) is disclosed in a Chinese utility model patent, comprising a filter bag body and an installation and pressing connection part. The installation and pressing connection part is arranged around the outside of the opening of the filter bag body. Multiple stitching supports are provided inside the bottom of the filter bag body, and adjacent stitching supports are interconnected. This novel filter bag, through the multiple stitching supports provided at the bottom of the filter bag body, allows for better support of the bottom of the filter bag body when filtering air, even when the amount of air to be filtered is small. This avoids prolonged filtration from the same position and enhances the air filtration effect.

[0004] While the aforementioned patent, through the design of structures such as the stitched support, can better support the bottom of the filter bag body when filtering air, even when the amount of air to be filtered is small, thus avoiding prolonged filtration from the same position, the dustproof environmentally friendly filter bag requires prolonged filtration of gas during use. This causes impurities in the gas to adhere to the inside of the dustproof environmentally friendly filter bag, clogging the filter pores. Once the filter pores are clogged, the dustproof environmentally friendly filter bag needs to be cleaned or replaced. This not only leads to the waste of the dustproof environmentally friendly filter bag, but also reduces the gas filtration efficiency because the gas emission needs to be stopped when replacing or cleaning the dustproof environmentally friendly filter bag. Furthermore, the dust collection within the limiting plate and elastic ring prevents dust from being stirred up and impacting the environment when the filter bag is replaced.

[0005] Therefore, this utility model provides an environmentally friendly filter bag for dust prevention to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This utility model provides an environmentally friendly filter bag for dust prevention, aiming to solve the problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a dust-proof environmentally friendly filter bag, comprising a filter bag, wherein a support mechanism is installed inside the filter bag, a vibration mechanism is installed on the surface of the support mechanism, and a snap-fit ​​mechanism is installed at one end of the support mechanism;

[0010] The vibration mechanism includes two sliding rods disposed on the surface of the support mechanism. One end of the two sliding rods is fixedly connected to an arc-shaped support plate, which corresponds to the filter bag. The other end of the sliding rods is fixedly connected to a connecting rod. One end of the two connecting rods is fixedly connected to a sliding block. One end of the sliding block is fixedly connected to a pulling rod. One end of the pulling rod is fixedly connected to an iron block. An electromagnetic coil is disposed on one side of the iron block. A protective sleeve is fitted over the surface of the electromagnetic coil. A power supply assembly is fixedly fitted over the surface of the protective sleeve. The power supply assembly and the electromagnetic coil are electrically connected via wires. A return spring is fixedly connected to the opposite side of the iron block and the protective sleeve.

[0011] As a preferred technical solution of this application, the support mechanism includes a support rod inserted into the filter bag, an mounting plate slidably connected to the surface of the support rod, a support plate rotatably connected to the surface of the mounting plate via a pin, and an elastic ring rotatably connected to one side of several support plates via pins.

[0012] As a preferred technical solution of this application, the support mechanism further includes two locking rods slidably connected to the surface of the support rod. One end of each locking rod is fixedly connected to an elastic block fixedly connected inside the support rod. The locking rods correspond to the mounting plate, and the mounting plate is locked to the surface of the support rod through the locking rods.

[0013] As a preferred technical solution of this application, the elastic ring is fixedly connected to the filter bag, and sliding grooves are provided on both sides of the surface of the support rod. The two connecting rods are slidably connected inside the sliding grooves, and the connecting rods and sliding rods are slidably connected to the mounting plate.

[0014] As a preferred technical solution of this application, the iron block and the sliding block are slidably connected inside the sliding groove, the surface of the arc-shaped support plate is provided with ventilation holes in a ring array, the ventilation holes are connected to the filter bag, and the inner arc surface of the elastic ring is fixedly connected to the limiting plate.

[0015] As a preferred technical solution of this application, the snap-fit ​​mechanism includes a mounting plate fixedly connected to one end of the support rod, and elastic abutment blocks are fixedly connected to the surface of the mounting plate in a ring array. The power supply assembly is fixedly connected to one side of the mounting plate by bolts.

[0016] (III) Beneficial Effects

[0017] By incorporating a vibration mechanism and a support mechanism, after prolonged use of the filter bag, the power supply component energizes the electromagnetic coil, causing it to attract the iron block. This allows the pull rod to detach the arc-shaped support plate from the filter bag. Subsequently, by de-energizing the electromagnetic coil, the return spring causes the arc-shaped support plate to impact the filter bag, resulting in vibration. This causes the dust adhering to the filter bag to fall to the bottom of the filter bag and be collected by the limiting plate. This reduces the need for filter bag replacement and cleaning, making the filter bag more convenient to use and achieving an environmentally friendly effect by reducing filter bag replacement.

[0018] By using a support mechanism and a snap-fit ​​mechanism, and through the cooperation of the support plate and the elastic ring, the filter bag is supported, preventing the filter bag from failing to support itself due to low gas flow and thus affecting filtration efficiency. Furthermore, the snap-fit ​​mechanism allows the support rod and the mounting plate to snap into the gas pipeline, making the support rod more stable during use, thereby making the vibration mechanism and support mechanism more stable during operation.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] This utility model provides an environmentally friendly filter bag for dust prevention, such as... Figures 1-5 As shown, the dust-proof environmentally friendly filter bag includes a filter bag 1. A support mechanism is installed inside the filter bag 1. A snap-fit ​​mechanism is installed at one end of the support mechanism. The snap-fit ​​mechanism includes a mounting plate 19 fixedly connected to one end of a support rod 11. Elastic abutment blocks 20 are fixedly connected to the surface of the mounting plate 19 in a ring array. The power supply assembly 10 is fixedly connected to one side of the mounting plate 19 by bolts. The support mechanism includes a support rod 11 inserted into the filter bag 1. The mounting plate 19 is inserted into the gas pipeline. The elastic force of the elastic abutment blocks 20 makes the mounting plate 19 snap into the gas pipeline, supporting the support rod 11.

[0028] A mounting plate 14 is slidably connected to the surface of the support rod 11. A support plate 12 is rotatably connected to the surface of the mounting plate 14 via a pin. An elastic ring 13 is rotatably connected to one side of several support plates 12 via pins. A limit plate 18 is fixedly connected to the inner arc surface of the elastic ring 13. The elastic ring 13 is fixedly connected to the filter bag 1. The support mechanism also includes two snap-fit ​​rods 15 slidably connected to the surface of the support rod 11. One end of the snap-fit ​​rod 15 is fixedly connected to an elastic block 16 fixedly connected inside the support rod 11. The snap-fit ​​rod 15 corresponds to the mounting plate 14. The mounting plate 14 is snapped onto the surface of the support rod 11 via the snap-fit ​​rod 15. The sliding mounting plate 14 slides on the surface of the support rod 11, so that the snap-fit ​​rod 15 is inserted into the interior of the mounting plate 14 via the elastic block 16, limiting the mounting plate 14. Thus, when the mounting plate 14 moves, it simultaneously drives the support plate 12 to unfold, supporting the elastic ring 13, thereby supporting the filter bag 1.

[0029] A vibration mechanism is installed on the surface of the support mechanism. The vibration mechanism includes two sliding rods 2 set on the surface of the support mechanism. One end of the two sliding rods 2 is fixedly connected to an arc-shaped support plate 3. The surface of the arc-shaped support plate 3 has a ring array of ventilation holes 17, which are connected to the filter bag 1. The arc-shaped support plate 3 corresponds to the filter bag 1. The other end of the sliding rod 2 is fixedly connected to a connecting rod 4. One end of the two connecting rods 4 is fixedly connected to a sliding block 5. One end of the sliding block 5 is fixedly connected to a pulling rod 6. Sliding grooves 21 are opened on both sides of the surface of the support rod 11. The two connecting rods 4 are slidably connected to the inside of the sliding grooves 21. The connecting rods 4 and the sliding rods 2 are slidably connected to the mounting plate 14. One end of the pulling rod 6 is fixedly connected to an iron block 7. The electromagnetic coil 8 is energized by the power supply component 10, so that the electromagnetic coil 8 attracts the iron block 7 and moves, thereby causing the pulling rod 6 to drive the sliding block 5 to move, and causing the two connecting rods 4 to drive the sliding rod 2 to move. At the same time, the arc-shaped support plate 3 and the filter bag 1 are no longer in contact, and the return spring 22 is compressed.

[0030] Both the iron block 7 and the sliding block 5 are slidably connected inside the sliding groove 21. An electromagnetic coil 8 is provided on one side of the iron block 7. A protective sleeve 9 is fitted on the surface of the electromagnetic coil 8. A power supply component 10 is fixedly fitted on the surface of the protective sleeve 9. The power supply component 10 and the electromagnetic coil 8 are electrically connected through wires. A return spring 22 is fixedly connected on opposite sides of the iron block 7 and the protective sleeve 9. Through the elastic force of the return spring 22, the sliding rod 2 pushes the arc-shaped support plate 3 to impact the inside of the filter bag 1, causing the filter bag 1 to vibrate and causing the dust attached to the filter bag 1 to fall below the filter bag 1.

[0031] Specifically, when using this dust-proof environmentally friendly filter bag: the mounting plate 19 is inserted into the gas pipeline. Through the elastic force of the elastic clamping block 20, the mounting plate 19 is locked into the gas pipeline, supporting the support rod 11. Then, the sliding mounting plate 14 slides on the surface of the support rod 11, so that the locking rod 15 is inserted into the interior of the mounting plate 14 through the elastic block 16, limiting the mounting plate 14. Thus, when the mounting plate 14 moves, it simultaneously drives the support plate 12 to unfold, supporting the elastic ring 13. This allows the elastic ring 13 to support the filter bag 1. At the same time, through the elastic force of the return spring 22, the sliding rod 2 pushes the arc-shaped support plate 3 to fit against the interior of the filter bag 1, thus supporting the filter bag 1. This prevents the filter bag 1 from failing to open due to low gas flow during use, thus affecting the filtration efficiency.

[0032] After prolonged use, the power supply assembly 10 energizes the electromagnetic coil 8, causing it to attract and move the iron block 7. This, in turn, causes the pulling rod 6 to move the sliding block 5, which in turn causes the two connecting rods 4 to move the sliding rod 2. Simultaneously, the arc-shaped support plate 3 no longer adheres to the filter bag 1, compressing the return spring 22. Then, the electromagnetic coil 8 is de-energized, preventing it from attracting the iron block 7. The return spring 22's elasticity causes the sliding rod 2 to push the arc-shaped support plate 3, impacting the interior of the filter bag 1. This vibration causes dust adhering to the filter bag 1 to fall to the bottom, where it is contained by the limiting plate 18 and the elastic ring 13. This prevents the filter bag 1 from becoming clogged after prolonged use, thus avoiding the need for replacement or cleaning. The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
