Description

Technical Field

[0001] This utility model relates to the field of dust collector filter bag disassembly technology, and in particular to a special tool for disassembling dust collector filter bags. Background Technology

[0002] In the daily operation and maintenance of industrial dust removal systems, the regular replacement of filter bags is a key link to ensure the filtration efficiency of the equipment. However, the dust removal filter bags currently in widespread use adopt a double-ring slot design at the mouth. Although this structure can ensure a stable connection between the filter bag and the equipment base plate, it brings great inconvenience when replacing damaged filter bags.

[0003] Because the gap between the filter bag retaining ring and the equipment base plate is small, operators often find it difficult to apply force precisely during disassembly. Moreover, traditional disassembly methods are not only time-consuming and labor-intensive, but also prone to wear on the filter bag edges and deformation of the retaining groove due to limited operating space. This can even cause damage to new filter bags before installation, increasing material costs and affecting the normal operation of the dust removal system. To completely solve this problem, we developed a special tool for disassembling dust collector filter bags. The tool has a special clamping structure designed at the head that can accurately and firmly clamp the retaining ring at the top of the filter bag, avoiding damage to the filter bag caused by improper contact with hands or ordinary tools in traditional operations. Summary of the Invention

[0004] The purpose of this utility model is to provide a special tool for disassembling dust collector filter bags, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a special tool for disassembling dust collector filter bags, including a dust collector filter bag and disassembly pliers. The dust collector filter bag is provided with a lower ring and an upper ring at its upper end, and a base plate is provided between the lower ring and the upper ring. The disassembly pliers include two sets of clamping rods hinged in the middle. Each set of clamping rods is provided with a gripping head at its bottom end. Each set of gripping heads is provided with a clamping ring groove inside. Each set of clamping rods is provided with a hand-held part at its top end.

[0006] As an improved technical solution, the inner wall of the clamping ring groove is provided with an anti-slip rubber pad, and the surface of the rubber pad is provided with a diamond-shaped anti-slip pattern.

[0007] As an improved technical solution, the hinge joint of the two sets of clamping rods is provided with an adjustable positioning bolt.

[0008] As an improved technical solution, the surface of the handheld part is provided with anti-slip texture, and the end of the handheld part is connected to a detachable extension rod.

[0009] As an improved technical solution, the gripping head and the gripping rod are detachably connected by a threaded structure.

[0010] After adopting the above technical solution, the beneficial effects of this utility model are: This invention utilizes a hinged clamping rod in the middle of the disassembly pliers to open and close. The clamping ring grooves on the gripping heads at the bottom of the two sets of clamping rods fit against the contours of the upper ring on both sides. The operator then applies pressure to the two sets of hand grips to control the gripping heads to clamp the upper ring. By rotating the two sets of clamping rods left and right, the gripping heads loosen the upper ring, breaking the tight connection between the upper ring and the equipment base plate. The two sets of hand grips are then pulled inwards smoothly, using the lever principle of the two sets of clamping rods to separate the upper ring from the equipment base plate. This lever-type design reduces the operating force, solving the problem of difficulty in applying force due to limited space in traditional disassembly methods. It effectively improves the compatibility between the disassembly pliers and the dust collector filter bag, ensuring stability when gripping the upper ring and preventing damage to the dust collector filter bag caused by misalignment of the upper ring. This also avoids filter bag damage caused by improper contact with hands or ordinary tools in traditional operations. Attached Figure Description

[0013] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0014] This utility model provides a technical solution: such as Figures 1 to 3 As shown in this embodiment, a special tool for disassembling a dust collector filter bag includes a dust collector filter bag 1 and a disassembly clamp 5. The upper end of the dust collector filter bag 1 is provided with a lower ring 2 and an upper ring 3. A base plate 4 is provided between the lower ring 2 and the upper ring 3. The disassembly clamp 5 includes two sets of clamping rods 6 hinged in the middle. The bottom end of each set of clamping rods 6 is provided with a gripping head 7. The inside of each set of gripping heads 7 is provided with a clamping ring groove 8. The top end of each set of clamping rods 6 is provided with a hand-held part 9.

[0015] By using the hinged clamping rods 6 in the middle to open and close the disassembly pliers 5, the clamping ring grooves 8 on the gripping heads 7 at the bottom of the two sets of clamping rods 6 can fit against the contours of the upper ring 3 on both sides. Then, the operator can apply pressure to the two sets of hand grips 9 to control the two sets of gripping heads 7 to clamp the upper ring 3. The operator can then rotate the two sets of clamping rods 6 left and right, thereby causing the two sets of gripping heads 7 to loosen the upper ring 3, thus breaking the tight connection between the upper ring 3 and the equipment base plate 4. Then, the two sets of hand grips 9 are pulled inward smoothly, and the upper ring 3 is separated from the equipment base plate 4 by lever principle of the two sets of clamping rods 6. The lever design reduces the operating force and solves the problem of difficulty in applying force due to the narrow space in traditional disassembly. It effectively improves the compatibility between the disassembly pliers 5 and the dust filter bag 1, and ensures the stability of the clamping ring grooves 8 when gripping the upper ring 3, preventing damage to the dust filter bag 1 caused by the deviation of the upper ring 3. It also avoids the filter bag damage caused by improper contact of hands or ordinary tools in traditional operations.

[0016] In other embodiments, the inner wall of the clamping ring groove 8 is provided with an anti-slip rubber pad, and the surface of the rubber pad is provided with a diamond-shaped anti-slip pattern; The friction between the clamping ring groove 8 and the upper ring 3 is increased by installing an anti-slip rubber pad in the clamping ring groove 8 to prevent slippage when clamping the upper ring 3. The diamond pattern can further improve the coefficient of friction, and can maintain a stable clamping even when there is dust on the surface of the dust filter bag 1, preventing the dust filter bag 1 from slipping off during the clamping process and reducing repeated operations. In addition, the rubber pad is elastic and can buffer the clamping force to prevent the upper ring 3 from being deformed by clamping.

[0017] In other embodiments, the hinge joint of the two sets of clamping rods 6 is provided with an adjustable positioning bolt; This design allows the positioning bolts to adjust the hinge tightness of the two sets of clamping rods 6, and to fix the opening and closing angle of the two sets of clamping rods 6, adapting to the clamping requirements of upper rings 3 of different specifications. After fixing the angle, the clamping force can be kept stable, avoiding the dust filter bag 1 from shaking due to changes in force during disassembly.

[0018] In other embodiments, the surface of the handheld part 9 is provided with anti-slip texture, and the end of the handheld part 9 is connected to a detachable extension rod; This design allows the extended rod to be threadedly connected to the handgrip 9, expanding the operating lever arm and thus solving the difficulty of working in narrow spaces. The anti-slip texture effectively increases the friction between the handgrip 9 and the hand, ensuring operational safety.

[0019] In other embodiments, the gripping head 7 and the gripping rod 6 are detachably connected by a threaded structure; By using a threaded connection structure between the clamping rod 6 and the clamping head 7, the clamping head 7 can be disassembled and replaced separately. When the clamping head 7 is worn or needs to be adapted to a different size upper ring 3, only the corresponding clamping head 7 needs to be replaced, thereby effectively reducing tool maintenance costs. There is no need to replace the entire disassembly pliers 5. At the same time, the adaptability of the disassembly pliers 5 is enhanced, which can meet the disassembly needs of filter bags of special specifications.

[0020] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
