Description

Technical Field

[0001] This utility model relates to the field of baghouse dust collectors, and more specifically, to a special tool for replacing dust collector bags. Background Technology

[0002] A bag filter is a dry dust filtration device 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 bag filter, larger and heavier dust particles settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is trapped, thus purifying the gas.

[0003] After a period of filtration, baghouse dust collectors require bag replacement to ensure proper filtration. Existing bag replacement methods involve removing the filter basket, then using a wrench or other tools to pry open the bag's rolled end in the mounting slot, installing a new bag into the slot, aligning the pre-formed bag, and then reinserting it into the filter basket. This process is cumbersome, and if the bag is not properly installed, the filter basket must be removed again. To improve replacement efficiency, enhance the adhesion between the bag and the filter basket, and reduce replacement difficulty, a specialized tool for replacing dust collector bags is proposed to address these issues. Utility Model Content

[0004] To overcome the shortcomings of existing technologies that require separate removal of the keel and dust collector bag before installation and replacement of the dust collector bag, resulting in low replacement efficiency, this utility model provides a special tool for replacing dust collector bags. The tool includes a support rod, an operating platform fixedly mounted on the top of the support rod, a lifting rod inserted into the center of the operating platform, an adjusting frame fixedly mounted on the bottom of the lifting rod, an adjusting component movably mounted on the inner wall of the adjusting frame, a movable clamping component engaging with the outer side of the adjusting component, and a counterweight positioning plate fixedly mounted on the end of the support rod furthest from the operating platform.

[0005] Preferably, the adjusting frame includes a frame body, which is fixedly installed at the bottom of the lifting rod. A bearing seat is fixedly installed on the inner wall of the frame body. One end of the adjusting component is movably installed inside the bearing seat. A linear slide rail is fixedly installed on the top of the inner wall of the frame body.

[0006] Preferably, the adjusting assembly includes a forward rotating screw, one end of which is movably installed inside the bearing housing, and the other end of which is fixedly installed with a connecting rod. A reverse rotating screw is fixedly installed at the end of the connecting rod away from the forward rotating screw, and an adjusting rod is fixedly installed at the end of the reverse rotating screw away from the connecting rod. The end of the adjusting rod away from the reverse rotating screw passes through the frame and extends to the outside of the frame.

[0007] Preferably, the movable clamping assembly includes two movable solenoids, which are respectively engaged with the outside of a forward-rotating screw and a reverse-rotating screw. Clamping plates are fixedly installed on the outside of each of the two movable solenoids. Limiting sliders are fixedly installed on the top of each of the two clamping plates, and both limiting sliders are slidably connected to a linear guide rail. A keel clamping plate is fixedly installed on the bottom of each of the two clamping plates. Vertical rods are fixedly installed on the inner walls of each of the two keel clamping plates, and dust bag clamping plates are fixedly installed on the bottom of each of the two vertical rods.

[0008] Preferably, the support rod has a slot inside, and an anti-fall component is inserted into the slot.

[0009] Preferably, the fall arrestor includes a push-pull rod, which is inserted into the interior of the slot, and a support base plate is fixedly installed at one end of the push-pull rod near the movable clamping component.

[0010] Preferably, the counterweight positioning disc is circular in shape, and a groove is provided at the bottom of the counterweight positioning disc.

[0011] Preferably, the lifting rod is T-shaped.

[0012] Beneficial effects:

[0013] The beneficial effects of adopting the technical solution of this utility model are as follows:

[0014] (1) By having movable screw tubes meshing with the outside of both the forward and reverse screws, when the adjusting rod is rotated, the two movable screw tubes will cause the clamping plate, the keel clamping plate and the dust bag clamping plate to move in opposite or separate directions. The keel clamping plate and the dust bag clamping plate are both "C" shaped, which can clamp the dust bag and the keel at the same time. Thus, during the disassembly process, the keel and the dust bag to be replaced can be disassembled together. After the dust bag is disassembled, the new dust bag can be directly installed on the outside of the keel. When it is reinstalled in the mounting slot, it can also be installed together. There is no need to separately remove, shape and treat the slot of the dust bag, which greatly reduces the difficulty of installation and improves the efficiency of installation.

[0015] (2) Install push-pull rods inside the support rods. When the staff moves the keel and dust bag up through the lifting rod, they can push the push-pull rods to make the supporting base plate located below the keel for support. This makes it easier for the staff to put on the dust bag without having to keep working on the lifting rods. This further reduces the difficulty of operation and improves the efficiency and convenience of replacement. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments. The specific embodiments are as follows:

[0025] like Figures 1 to 5 As shown, a special tool for replacing dust collector bags includes a support rod 1, an operating platform 2 fixedly mounted on the top of the support rod 1, a lifting rod 3 inserted into the center of the operating platform 2, an adjusting frame 4 fixedly mounted on the bottom of the lifting rod 3, an adjusting component 5 movably mounted on the inner wall of the adjusting frame 4, a movable clamping component 6 engaging with the outside of the adjusting component 5, a counterweight positioning plate 8 fixedly mounted on the end of the support rod 1 away from the operating platform 2, and the adjusting frame 4 including a frame body 40 fixedly mounted on the bottom of the lifting rod 3, with a shaft fixedly mounted on the inner wall of the frame body 40. The bearing seat 41 has one end of the adjusting component 5 movably mounted inside it. A linear slide rail 42 is fixedly mounted on the top of the inner wall of the frame 40. The adjusting component 5 includes a forward rotating screw 50, one end of which is movably mounted inside the bearing seat 41. A connecting rod 51 is fixedly mounted on the other end of the forward rotating screw 50. A reverse rotating screw 52 is fixedly mounted on the end of the connecting rod 51 away from the forward rotating screw 50. An adjusting rotating rod 53 is fixedly mounted on the end of the reverse rotating screw 52 away from the connecting rod 51. The end of the adjusting rotating rod 53 away from the reverse rotating screw 52 passes through the frame. 40 extends to the outside of the frame 40. The movable clamping assembly 6 includes two movable screw tubes 60, which are respectively engaged with the outside of the forward-rotating screw 50 and the reverse-rotating screw 52. Clamping plates 62 are fixedly installed on the outside of each of the two movable screw tubes 60. Limiting sliders 61 are fixedly installed on the top of each of the two clamping plates 62. Both limiting sliders 61 are slidably connected to the linear slide rail 42. Keel clamping plates 63 are fixedly installed on the bottom of each of the two clamping plates 62. Vertical rods are fixedly installed on the inner walls of each of the two keel clamping plates 63. 64. Dust bag clamps 65 are fixedly installed at the bottom of both vertical rods 64. Since the forward screw 50 and the reverse screw 52 are connected by the connecting rod 51, and the movable screw tubes 60 are engaged on the outside of both the forward screw 50 and the reverse screw 52, ​​when the adjusting rod 53 is rotated, the reverse screw 52 will drive the connecting rod 51 and the forward screw 50 to rotate together. Since the thread direction is not the same, the two movable screw tubes 60 will move in a relative or separate direction, thereby changing the spacing and position of the two clamping plates 62, the keel clamp 63 and the dust bag clamp 65.

[0026] It should be noted that both the keel clamp 63 and the dust bag clamp 65 are C-shaped. The dust bag clamp 65 is slightly larger than the keel clamp 63, which serves to clamp and limit the dust bag.

[0027] like Figures 1 to 5As shown, the support rod 1 has an internal slot, and a fall protection component 7 is inserted into the slot. The fall protection component 7 includes a push-pull rod 70, which is inserted into the slot. A support base plate 71 is fixedly installed at the end of the push-pull rod 70 near the movable clamping component 6. The lifting rod 3 can drive the adjusting frame 4 and the movable clamping component 6 to rise or fall. When the movable clamping component 6 clamps the keel and the dust bag, it can be driven to rise by the lifting rod 3. At the same time, the push-pull rod 70 is pushed so that the support base plate 71 is located under the keel for support, which makes it convenient for the staff to position the bag. The replacement work can be started without controlling the lifting rod 3.

[0028] In addition, the counterweight positioning plate 8 is circular in shape and has a groove at the bottom. The counterweight positioning plate 8 has its own weight. When replacing a dust bag, the counterweight positioning plate 8 at the bottom of the support rod 1 can be inserted and covered with the surrounding protruding keel, so that the support rod 1 is stable and will not shift. It provides stability and can be carried at any time, with good convenience and operability.

[0029] It should be noted that the lifting rod 3 is T-shaped. The shape of the lifting rod 3 is designed to make it easy for the operator to hold and comfortable, and also to prevent the lifting rod 3 from detaching from the operating table 2 during the falling process.

[0030] Working principle: By adjusting the frame 4, the lifting rod 3 and the adjusting component 5 are connected simultaneously. When replacing the dust collector bag, the counterweight positioning plate 8 is first inserted into the keel near the point where the dust collector bag needs to be replaced, so that the support rod 1 is stably positioned. At the same time, the operator moves the lifting rod 3 to bring the two keel clamps 63 and the dust collector bag clamp 65 close to the dust collector bag to be replaced. According to the size of the dust collector bag and the keel, the adjusting component 5 is rotated to open the two keel clamps 63 and the dust collector bag clamp 65 and fit them into the keel and the dust collector bag respectively. The dust collector bag clamp 65 is thinner and can be inserted into the gap below the rolled-up part of the dust collector bag, while the keel clamp 63 is inserted into the keel. Above the bottom and the rolled-up part of the dust bag, the dust bag is fixed by the keel clamp 63 and the dust bag clamp 65 during the operator's lifting of the lifting rod 3. It can move up with the keel and detach from the mounting slot. Then, the operator can push the push-pull rod 70 to support the bottom plate 71 under the keel. At this time, the dust bag is very easy to remove from the outside of the keel. At the same time, a new dust bag can be directly placed on the outside of the keel. Finally, the keel and the dust bag can be directly reinstalled into the mounting slot. There is no need to remove the dust bag separately, and the problems of positioning and pre-treatment during installation are avoided, which significantly improves the replacement efficiency.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
