Description

Technical Field

[0001] This utility model relates to the field of filter bag technology, specifically to a high-efficiency dust filter bag. Background Technology

[0002] In industrial production processes, dust pollution not only causes serious damage to the environment but also threatens the health of workers. As a core component of industrial dust removal systems, dust filter bags play a crucial role in intercepting dust and purifying gases, and are therefore widely used.

[0003] An investigation revealed that a Chinese utility model patent discloses an anti-clogging dust collector filter bag (publication number: CN222019120U), comprising: a fixed sleeve and a rotating sleeve, the fixed sleeve being located above the rotating sleeve; a dust collector filter bag body disposed at the bottom of the rotating sleeve; a base plate disposed at the bottom of the dust collector filter bag body; a counterweight embedded in the bottom of the base plate; a gear ring fixed to the outer wall of the rotating sleeve by adhesive; a motor fixed to the outer wall of the fixed sleeve by bolts; a gear fixed to the output end of the motor; a flange welded to the top of the fixed sleeve; and a support rod welded to the bottom of the flange near the outer side of the fixed sleeve. When the dust collector filter bag body rotates, its bottom is eccentrically thrown up, and under the obstruction of a retaining ring, the dust collector filter bag body impacts the retaining ring, causing dust to fall off the outer wall of the dust collector filter bag body, thus cleaning the outer wall of the dust collector filter bag body and preventing clogging.

[0004] Although the aforementioned patent achieves its goal of cleaning the outer wall of the dust collector filter bag by causing the bottom of the filter bag to swing eccentrically during rotation and impacting the retaining ring, thus preventing clogging, the contact area between the filter bag and the retaining ring experiences significant friction and impact forces during this process. Over time, this leads to gradual wear and tear at the contact area, resulting in filter bag damage and significantly shortening its lifespan.

[0005] Therefore, this utility model provides a high-efficiency dust filter bag to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a solution to the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency dust filter bag, comprising a mounting frame, a filter bag skeleton, and a filter bag body disposed outside the filter bag skeleton. The bottom end of the filter bag skeleton is fixedly connected to the bottom upper surface of the mounting frame. Connecting frames are fixedly connected to both the upper and lower ends of the inner side of the mounting frame. A connecting rod is rotatably connected to the lower surface of one of the connecting frames. A reciprocating screw is fixedly connected to the bottom end of the connecting rod. The bottom end of the reciprocating screw is rotatably connected to the upper surface of the other connecting frame. A support frame A is movably connected to the outer side of the reciprocating screw. A folded airbag is fixedly mounted on the upper surface of the support frame A. A support frame B is fixedly connected to the upper surface of the folded airbag. The outer side of the support frame B is fixedly connected to the inner side of the filter bag skeleton. Multiple connecting pipes are arranged above the support frame B, and the bottom ends of the multiple connecting pipes penetrate the inner wall of the support frame B and communicate with the folded airbag. Multiple unidirectional air blowing ends are connected to the outer side of each connecting pipe.

[0008] As a preferred technical solution of this application, a one-way air inlet is provided below the support frame A, and one end of the one-way air inlet penetrates the interior of the support frame A and communicates with the folding airbag.

[0009] As a preferred technical solution of this application, the inner side of the filter bag skeleton is provided with a plurality of limiting grooves, and the inner sides of the plurality of limiting grooves are slidably connected to the protrusions at the outer end of the support frame A.

[0010] As a preferred technical solution of this application, a connecting seat is provided on the filter bag frame, and the top end of the connecting seat is fixedly connected to the inner side of the mounting frame. Both the bottom end of the connecting seat and the top end of the filter bag frame are provided with annular grooves, and a rotating toothed ring is rotatably connected between the inner sides of the two annular grooves.

[0011] As a preferred technical solution of this application, a mounting bracket is fixedly connected to the outer side of the connecting seat, a drive motor is fixedly installed on the inner side of the mounting bracket, a drive gear is fixedly connected to the output shaft of the drive motor, and the teeth of the drive gear mesh with the teeth of the rotating gear ring.

[0012] As a preferred technical solution of this application, a fixing frame is fixedly connected to the inner side of the rotating gear ring, and the inner side of the fixing frame is fixedly connected to the outer side of the connecting rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The support frame A moves up and down along the outer edge of the reciprocating screw. When the support frame A moves upward, it compresses the folded airbag. As the folded airbag is compressed, the gas inside is delivered to the one-way blowing end through multiple connecting pipes and ejected at high speed from the one-way blowing end. This high-speed airflow acts on the inner side of the filter bag body, blowing off the dust adhering to the filter bag body. This cleaning is achieved through the airflow inside the folded airbag, preventing the filter bag body from directly rubbing against other parts during cleaning. This reduces the wear and tear on the filter bag body caused by direct contact and friction with other parts, thus extending the service life of the filter bag body. Attached Figure Description

[0022] 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.

[0023] Please see Figures 1-5As shown, the purpose of this embodiment is to provide a high-efficiency dust filter bag, including a mounting frame 1, a filter bag frame 2, and a filter bag body 3 disposed outside the filter bag frame 2. The bottom end of the filter bag frame 2 is fixedly connected to the bottom upper surface of the mounting frame 1. Connecting frames 4 are fixedly connected to both the upper and lower ends of the inner side of the mounting frame 1. A connecting rod 5 is rotatably connected to the lower surface of one of the connecting frames 4. A reciprocating screw 6 is fixedly connected to the bottom end of the connecting rod 5. The bottom end of the reciprocating screw 6 is rotatably connected to the upper surface of the other connecting frame 4. A support frame A is movably connected to the outer side of the reciprocating screw 6. 7. A folded airbag 8 is fixedly installed on the upper surface of the support frame A7. A support frame B9 is fixedly connected to the upper surface of the folded airbag 8. The outer side of the support frame B9 is fixedly connected to the inner side of the filter bag frame 2. Multiple connecting pipes 10 are provided above the support frame B9, and the bottom ends of the multiple connecting pipes 10 all penetrate through the inner wall of the support frame B9 and communicate with the folded airbag 8. Multiple one-way blowing ends 11 are connected to the outer side of the connecting pipes 10. A one-way air inlet end 12 is provided below the support frame A7, and one end of the one-way air inlet end 12 penetrates through the interior of the support frame A7 and communicates with the folded airbag 8.

[0024] In this embodiment, the reciprocating screw 6 rotates, which drives the support frame A7 to move up and down along the outer edge of the reciprocating screw 6. When the support frame A7 moves upward, it compresses the folded airbag 8. While the folded airbag 8 is being compressed, the gas inside the folded airbag 8 is transported to the one-way blowing end 11 through multiple connecting pipes 10 and ejected at high speed from the one-way blowing end 11. This high-speed airflow acts on the inner side of the filter bag body 3, thereby blowing off the dust attached to the filter bag body 3, thus achieving the purpose of dust removal. When the support frame A7 moves downward, the folded airbag 8 expands, forming a negative pressure inside. At this time, external air enters the folded airbag 8 through the one-way air inlet 12, storing gas for the next compression jet dust removal process. Dust removal is carried out by the airflow inside the folded airbag 8, so that the filter bag body 3 does not directly rub against other parts during dust removal, thereby reducing the wear of the filter bag body 3 caused by direct contact and friction with other parts, and thus extending the service life of the filter bag body 3.

[0025] In this embodiment, as Figure 1 and Figure 2As shown, a connecting seat 14 is provided on the filter bag frame 2, and the top end of the connecting seat 14 is fixedly connected to the inner side of the mounting frame 1. Both the bottom end of the connecting seat 14 and the top end of the filter bag frame 2 are provided with annular grooves 15, and a rotating gear ring 16 is rotatably connected between the inner sides of the two annular grooves 15. A mounting bracket 17 is fixedly connected to the outer side of the connecting seat 14, and a drive motor 18 is fixedly installed on the inner side of the mounting bracket 17. A drive gear 19 is fixedly connected to the output shaft of the drive motor 18, and the teeth of the drive gear 19 mesh with the teeth of the rotating gear ring 16. A fixing frame 20 is fixedly connected to the inner side of the rotating gear ring 16, and the inner side of the fixing frame 20 is fixedly connected to the outer side of the connecting rod 5.

[0026] In this embodiment, by starting the drive motor 18, the output shaft of the drive motor 18 drives the drive gear 19 to rotate. Then, while the drive gear 19 is rotating, it meshes with the rotating gear ring 16, causing the rotating gear ring 16 to rotate within the annular groove 15 opened at the bottom of the connecting seat 14 and the top of the filter bag frame 2. Then, while the rotating gear ring 16 is rotating, it drives the connecting rod 5 to rotate synchronously through the fixing frame 20. Then, when the connecting rod 5 rotates, it drives the reciprocating screw 6 to rotate synchronously. When the reciprocating screw 6 rotates, it also rotates. When the reciprocating screw 6 rotates, it drives the support frame A7 to move up and down along the outer edge of the reciprocating screw 6. In this way, the up and down reciprocating motion of the support frame A7 compresses and expands the folded airbag 8.

[0027] In this embodiment, as Figure 4 and Figure 5 As shown, the filter bag frame 2 has multiple limiting grooves 13 on its inner side, and the inner sides of the multiple limiting grooves 13 are slidably connected to the protrusions at the outer ends of the support frame A7.

[0028] In this embodiment, the limiting groove 13 on the inner side of the filter bag frame 2 is slidably connected to the protrusion at the outer end of the support frame A7, which provides guidance for the up and down movement of the support frame A7, ensures the stability of its movement, and prevents the support frame A7 from deviating during the movement.

[0029] In summary, the working principle of this utility model is as follows:

[0030] In use, by starting the drive motor 18, the output shaft of the drive motor 18 drives the drive gear 19 to rotate. Simultaneously, the drive gear 19 meshes with the rotating gear ring 16, causing the rotating gear ring 16 to rotate within the annular groove 15 at the bottom of the connecting seat 14 and the top of the filter bag frame 2. The rotating gear ring 16, in turn, drives the connecting rod 5 to rotate synchronously via the fixed frame 20. The rotating connecting rod 5 then drives the reciprocating screw 6 to rotate synchronously, causing the reciprocating screw 6 to rotate as well. This rotation of the reciprocating screw 6 causes the support frame A7 to reciprocate up and down along its outer edge. When the support frame A7 moves upward, it compresses the folded airbag 8. When the folded airbag 8 is compressed... Meanwhile, the gas inside the folded airbag 8 is delivered to the one-way blowing end 11 through multiple connecting pipes 10 and ejected at high speed from the one-way blowing end 11. This high-speed airflow acts on the inner side of the filter bag body 3, thereby blowing off the dust attached to the filter bag body 3, thus achieving the purpose of dust removal. When the support frame A7 moves downward, the folded airbag 8 expands, forming a negative pressure inside. At this time, external air enters the folded airbag 8 through the one-way air inlet 12, storing gas for the next compressed air jet dust removal process. Dust removal is carried out through the airflow inside the folded airbag 8, so that the filter bag body 3 does not directly rub against other parts during dust removal, thereby reducing the wear and tear of the filter bag body 3 caused by direct contact and friction with other parts, and thus extending the service life of the filter bag body 3.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
