Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, and more specifically, to a dust removal device for paper towel production. Background Technology

[0002] In existing dust removal devices used in paper towel production, the inconvenience of installing and disassembling filter bag components and the difficulty of removing waste from filter bags have become important technical bottlenecks restricting the efficient operation and maintenance management of dust removal equipment.

[0003] First, the filter bags of traditional dust removal devices are mostly installed using bolt fixing or snap-fit ​​connections. This design has obvious operational inconveniences. Operators need to work in the confined space inside the cabinet and often need to use special tools to tighten or loosen the bolts one by one. This is not only time-consuming and laborious, but also makes the threaded connections easy to be clogged by dust in the dusty environment of paper towel production, making disassembly and assembly even more difficult. At the same time, the traditional snap-fit ​​structure lacks an effective positioning mechanism, requiring repeated adjustments to the position during installation, which increases the complexity of operation.

[0004] Traditional dust collection devices mainly rely on gravity settling and static filtration, lacking active dust removal capabilities. The fibrous dust generated during the paper towel production process is lightweight, fine, and easily adheres, readily forming a dense dust layer on the surface of the filter bag. Once formed, this dust layer is difficult to remove by wind alone, leading to a sharp decrease in the air permeability of the filter bag, a significant reduction in filtration efficiency, and ultimately affecting the performance of the entire dust collection system.

[0030] Please see Figures 1-5A dust removal device for tissue paper production includes a dust removal mechanism, a mounting and clamping mechanism, and a vibration mechanism. The dust removal mechanism includes a cabinet 1, a dust removal fan 2, a collection frame 3, and filter bag assemblies 4. The dust removal fan 2 is installed at the top of the cabinet 1, with one end of the fan extending into the top of the cabinet 1. The collection frame 3 is slidably disposed inside the cabinet 1. Multiple sets of filter bag assemblies 4 are installed at the bottom of the collection frame 3 via the mounting and clamping mechanism. The mounting and clamping mechanism includes a clamping pipe 5, a clamping rod 6, a clamping groove 7, and a push-out mechanism. The device includes a spring 8, an insertion frame 9, a rotating sleeve 10, and an inner pressure groove 11. The retaining tube 5 extends directionally into the retaining tube 5. The retaining groove 7 is located on the side wall of the retaining rod 6. The insertion frame 9 is laterally slidably mounted on the side wall of the retaining tube 5. The rotating sleeve 10 is rotatably mounted on the outer wall of the retaining tube 5. The inner pressure groove 11 is located on the inner wall of the rotating sleeve 10. The ejection spring 8 is mounted in the retaining groove 7, and the inner pressure groove 11 presses against the insertion frame 9 as it extends into the retaining groove 7, compressing the ejection spring 8. The rotating sleeve 10 is rotated in the opposite direction, and the ejection spring 8 pushes the insertion frame 9 away from the retaining groove 7.

[0031] In this embodiment, after the dust removal fan 2 is started, it draws dust-laden air into the cabinet 1. The air is filtered by multiple sets of filter bag assemblies 4 installed at the bottom of the container rack 3. The dust is trapped on the surface of the filter bags, and the purified air is discharged from the dust removal fan 2. The filtered dust eventually falls into the collection drawer 19 at the bottom of the cabinet 1. The snap-fit ​​rod 6 is inserted into the snap-fit ​​tube 5. The snap-fit ​​groove 7 on the side wall of the snap-fit ​​rod 6 is aligned with the extension frame 9 on the side wall of the snap-fit ​​tube 5. The rotating sleeve 10 is rotated so that the inner pressure groove 11 on the inner wall of the rotating sleeve 10 presses against the extension frame 9, pushing the extension frame 9 into the snap-fit ​​groove 7 and compressing the push-out spring 8 in the snap-fit ​​groove 7, thus completing the fixed connection between the filter bag assembly 4 and the container rack 3. The rotating sleeve 10 is rotated in the opposite direction, the inner pressure groove 11 disengages from the extension frame 9, and the push-out spring 8 in the snap-fit ​​groove 7 releases its force to push the extension frame 9 away from the snap-fit ​​groove 7. The snap-fit ​​rod 6 separates from the snap-fit ​​tube 5, realizing the quick disassembly of the filter bag assembly 4.

[0032] The vibration mechanism includes an inner frame 12, a linear motor 13, a drive rod 14, a top block 15, a sliding rod 16, and a stabilizing spring 17. The inner frame 12 is fixedly installed inside the cabinet 1. The linear motor 13 is installed on the inner frame 12. The drive rod 14 is slidably installed on the inner frame 12. The output end of the linear motor 13 is connected to the sliding rod 16. One end of the sliding rod 16 is connected to the container 3. The sliding rod 16 is installed around the container 3. The top block 15 is installed at one end of the sliding rod 16. The stabilizing spring 17 is installed between the top block 15 and the inner frame 12. The top block 15 reciprocates in contact with the inner frame 12 to generate vibration.

[0033] In this embodiment, after the linear motor 13 is started, its output end drives the sliding rod 16 to reciprocate. The sliding rod 16 drives the container frame 3 to vibrate. At the same time, the top block 15 installed at one end of the sliding rod 16 reciprocates in contact with the inner frame 12, generating impact vibration. The stabilizing spring 17 between the top block 15 and the inner frame 12 provides a restoring force and a buffering effect. The vibration is transmitted to the filter bag assembly 4, causing the dust attached to the surface of the filter bag to fall off and restoring the filtration efficiency of the filter bag.

[0034] Please see Figures 1-5 As a supplementary embodiment of a dust removal device for tissue paper production, which includes a dust removal mechanism, a mounting clamping mechanism, and a vibration mechanism: A cabinet door 18 is rotatably installed at the open end of the front face of the cabinet 1; a collection drawer 19 is slidably installed at the bottom end of the cabinet 1; the bottom end of the filter bag assembly 4 is opposite to the collection drawer 19; a connecting plate 20 is installed at the bottom end of the side wall of the clamping pipe 5; the connecting plate 20 is fixedly installed on the container rotating frame; a support ring 21 is installed at the bottom end of the rotating sleeve 10; a rotating rail 22 is installed on the outer wall of the clamping pipe 5; the inner wall of the support ring 21 is rotated and guided in cooperation with the rotating rail 22; one end of the clamping rod 6 is connected to the track assembly; and the other end of the clamping rod 6 extends through the container frame 3 and engages with the clamping pipe 5; and supports 23 are installed around the bottom end of the cabinet 1.

[0035] More specifically, start the dust removal fan 2 to begin the dust collection and filtration work. The dust-laden air is filtered through the filter bag assembly 4, and the dust is trapped on the surface of the filter bag. The vibration mechanism is started periodically to remove the dust accumulated on the filter bag. The detached dust is collected in the bottom drawer. When maintenance is required, the equipment can be accessed through the cabinet door 18. When the filter bag needs to be replaced, the filter bag assembly can be quickly disassembled and assembled using the installation snap-fit ​​mechanism.

[0036] In summary, when the overall equipment is in use or running: when the dust removal mechanism needs to run, the dust removal fan 2 starts and draws dust-laden air into the cabinet 1. The air is filtered by multiple sets of filter bag assemblies 4 installed at the bottom of the collection rack 3. The dust is trapped on the surface of the filter bags, and the purified air is discharged from the dust removal fan 2. The filtered dust eventually falls into the collection drawer 19 at the bottom of the cabinet 1.

[0037] When the snap-fit ​​mechanism needs to be installed, insert the snap-fit ​​rod 6 into the snap-fit ​​tube 5. Align the snap-fit ​​groove 7 on the side wall of the snap-fit ​​rod 6 with the extension frame 9 on the side wall of the snap-fit ​​tube 5. Rotate the rotating sleeve 10 so that the inner pressure groove 11 on the inner wall of the rotating sleeve 10 presses against the extension frame 9, pushing the extension frame 9 into the snap-fit ​​groove 7 and compressing the push-out spring 8 in the snap-fit ​​groove 7, thus completing the fixed connection between the filter bag assembly 4 and the container frame 3. Rotate the rotating sleeve 10 in the opposite direction, and the inner pressure groove 11 disengages from the extension frame 9. The push-out spring 8 in the snap-fit ​​groove 7 releases its force and pushes the extension frame 9 away from the snap-fit ​​groove 7, thus separating the snap-fit ​​rod 6 from the snap-fit ​​tube 5 and realizing the quick disassembly of the filter bag assembly 4.

[0038] When the vibration mechanism is required to operate, the linear motor 13 starts and its output end drives the sliding rod 16 to reciprocate. The sliding rod 16 drives the container frame 3 to vibrate. At the same time, the top block 15 installed at one end of the sliding rod 16 reciprocates in contact with the inner frame 12, generating impact vibration. The stabilizing spring 17 between the top block 15 and the inner frame 12 provides a restoring force and buffering effect. The vibration is transmitted to the filter bag assembly 4, causing the dust attached to the surface of the filter bag to fall off and restoring the filtration efficiency of the filter bag.

[0039] Start the dust removal fan 2 to begin the dust collection and filtration process. Dust-laden air is filtered through the filter bag assembly 4, and dust is trapped on the surface of the filter bag. The vibration mechanism is activated periodically to remove the accumulated dust on the filter bag. The detached dust is collected in the bottom drawer. When maintenance is required, the equipment can be accessed through the cabinet door 18. When the filter bag needs to be replaced, the filter bag assembly can be quickly disassembled and reassembled using the installation snap-fit ​​mechanism.

[0040] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
