Description

Technical Field

[0001] This invention relates to the field of industrial filtration technology, and specifically to a drawer-type quick-release filter cartridge structure. Background Technology

[0002] Dust removal is a technology that captures and separates solid particles such as dust from dust-laden airflow. A dust collector is a device used to capture and separate dust particles suspended in air or gas. The filter cartridge is the filtration element of a cartridge dust collector and also its core component. The filter cartridge consists of four parts: a top cover, a metal frame, pleated filter media, and a base. The performance of the filter cartridge directly affects the performance of the dust collector.

[0003] In traditional cartridge dust collectors, filter cartridges are typically fixed and sealed using bolts. While this method ensures the reliability and airtightness of the cartridges during gas filtration, it makes disassembly extremely inconvenient and hinders the installation and maintenance of the dust collector. When the filter cartridges reach the end of their service life, maintenance personnel must first remove the door and sealing plate of the back-flushing chamber before they can reach into the chamber to loosen the locking nuts on the filter cartridges. During this process, other maintenance personnel must assist in opening the door of the filter cartridge chamber, supporting the disassembled cartridge with their hands before removing it from the chamber. Repeat the above process until all the filter cartridges that need to be replaced have been disassembled. Then, one maintenance worker needs to hold the filter cartridges in the filter cartridge compartment by hand, while another worker tightens the locking nuts on each filter cartridge individually in the backflushing compartment. This process continues until all the new filter cartridges are installed into the dust collector. Finally, close the filter cartridge compartment door and lock the backflushing compartment door and sealing plate. Only then is the entire filter cartridge maintenance process complete. The entire filter cartridge maintenance process is extremely time-consuming and labor-intensive. The specific maintenance time depends on the number of filter cartridges that need to be replaced, ranging from half an hour to several hours. During the filter cartridge maintenance, the dust collector remains stopped and cannot operate, failing to filter the dust-laden airflow generated during the production process. This negatively impacts the company's production efficiency.

[0004] Currently, there are some improved solutions on the market to address the inconvenience of disassembling traditional filter cartridges, mainly lug-type and rotary filter cartridges. However, both of these structures have significant drawbacks. To ensure the filter cartridge's sealing, a large axial clamping force needs to be applied. This clamping force results in maintenance personnel needing to provide very high torque for disassembling lug-type and rotary filter cartridges, requiring significantly more force than traditional bolt-type cartridges. If the maintenance personnel lack sufficient arm strength, the filter cartridge may be unable to be disassembled. Secondly, due to the small area of ​​the connection points of these two types of filter cartridges, the area where the filter cartridge is fixed to the dust collector will bear significant pressure after the clamping force is applied. Connection failure often originates from this point. Based on this, considering the stress strength of the filter cartridge connection points, the height of lug-type and rotary filter cartridges is limited; the height of the filter cartridge cannot be made too high. Therefore, the application scenarios for lug-type and rotary filter cartridges are limited. Summary of the Invention

[0005] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this invention is to provide a drawer-type quick-release filter cartridge structure, which realizes the quick assembly and disassembly of the filter cartridge by pushing and pulling, while ensuring the airtightness between the filter cartridge and the support, and has stronger applicability.

[0006] This invention is achieved through the following technical solution:

[0007] A drawer-type quick-release filter cartridge structure includes a support, a filter cartridge, and a movable component. The support has a through hole for exposing the filter cartridge, and the movable component is connected to one side of the filter cartridge. One side of the support has a plurality of first arc-shaped grooves, and one side of the movable component has a first guide component, which is movably disposed within the first arc-shaped grooves. When the first guide component moves from one end of the first arc-shaped groove away from the through hole to the other end closer to the through hole, the opening of the filter cartridge gradually approaches the through hole and eventually presses against the support.

[0008] The quick-release structure also includes a handle, one end of which is rotatably connected to the end of the movable part that is near the first arc-shaped groove and away from the through hole.

[0009] The quick-release structure further includes a connecting plate, one end of which is rotatably connected to the end of the movable part near the handle and the end of the bracket near the handle, respectively. The other end of the connecting plate is provided with a second arc-shaped groove, a first straight groove communicating with the second arc-shaped groove, and a second straight groove collinear with the first straight groove. The length direction of the first straight groove is parallel to the length direction of the connecting plate. One end of the handle is provided with a second guide and a third guide. The second guide is movably disposed in the second arc-shaped groove and the first straight groove, and the third guide is movably disposed in the second straight groove.

[0010] The bracket has a first guide groove at one end near the connecting plate, and the movable part has a second guide groove at one end near the connecting plate. Both the first and second guide grooves are open on the outside. The opening direction of the first guide groove is parallel to the length direction of the movable part, and the opening direction of the first guide groove intersects perpendicularly with the opening direction of the second guide groove. The movable part has a fourth guide at one end near the connecting plate, and the bracket has a fifth guide at one end near the connecting plate. The movable part is rotatably connected to the connecting plate via the fourth guide, and the bracket is rotatably connected to the connecting plate via the fifth guide. When the movable part moves towards the through hole, the fifth guide disengages from the second guide groove while the fourth guide extends into the first guide groove. When the movable part moves away from the through hole, the fourth guide disengages from the first guide groove while the fifth guide extends into the second guide groove.

[0011] The movable component is provided with a slide rail, and the upper end of the filter cartridge is arranged to abut against the slide rail.

[0012] One end of the slide rail is provided with a limiting element.

[0013] The beneficial effects of this invention are:

[0014] This invention provides a drawer-type quick-release filter cartridge structure. After the filter cartridge is installed on the movable part, the movable part is moved towards the through hole, causing the first guide to move upward along the first arc-shaped groove. When the first guide abuts against the uppermost end of the first arc-shaped groove, the filter cartridge presses against the bracket, increasing the friction between the first guide and the first arc-shaped groove. Finally, the first guide and the first arc-shaped groove are locked together, thus completing the installation of the filter cartridge. This invention achieves the engagement of the first arc-shaped groove on the bracket and the first guide on the movable part through a push-pull mechanism, thereby enabling quick assembly and disassembly of the filter cartridge while ensuring airtightness between the filter cartridge and the bracket, thus broadening its applicability.

[0025] Dust removal is a technology that captures and separates solid particles such as dust from dust-laden airflow. A dust collector is a device used to capture and separate dust particles suspended in air or gas. The filter cartridge is the filtration element of a cartridge dust collector and also its core component. The filter cartridge consists of four parts: a top cover, a metal frame, pleated filter media, and a base. The performance of the filter cartridge directly affects the performance of the dust collector.

[0026] In traditional cartridge dust collectors, filter cartridges are typically fixed and sealed using bolts. While this method ensures the reliability and airtightness of the cartridges during gas filtration, it makes disassembly extremely inconvenient and hinders the installation and maintenance of the dust collector. When the filter cartridges reach the end of their service life, maintenance personnel must first remove the door and sealing plate of the back-flushing chamber before they can reach into the chamber to loosen the locking nuts on the filter cartridges. During this process, other maintenance personnel must assist in opening the door of the filter cartridge chamber, supporting the disassembled cartridge with their hands before removing it from the chamber. Repeat the above process until all the filter cartridges that need to be replaced have been disassembled. Then, one maintenance worker needs to hold the filter cartridges in the filter cartridge compartment by hand, while another worker tightens the locking nuts on each filter cartridge individually in the backflushing compartment. This process continues until all the new filter cartridges are installed into the dust collector. Finally, close the filter cartridge compartment door and lock the backflushing compartment door and sealing plate. Only then is the entire filter cartridge maintenance process complete. The entire filter cartridge maintenance process is extremely time-consuming and labor-intensive. The specific maintenance time depends on the number of filter cartridges that need to be replaced, ranging from half an hour to several hours. During the filter cartridge maintenance, the dust collector remains stopped and cannot operate, failing to filter the dust-laden airflow generated during the production process. This negatively impacts the company's production efficiency.

[0027] Currently, there are some improved solutions on the market to address the inconvenience of disassembling traditional filter cartridges, mainly lug-type and rotary filter cartridges. However, both of these structures have significant drawbacks. To ensure the filter cartridge's sealing, a large axial clamping force needs to be applied. This clamping force results in maintenance personnel needing to provide very high torque for disassembling lug-type and rotary filter cartridges, requiring significantly more force than traditional bolt-type cartridges. If the maintenance personnel lack sufficient arm strength, the filter cartridge may be unable to be disassembled. Secondly, due to the small area of ​​the connection points of these two types of filter cartridges, the area where the filter cartridge is fixed to the dust collector will bear significant pressure after the clamping force is applied. Connection failure often originates from this point. Based on this, considering the stress strength of the filter cartridge connection points, the height of lug-type and rotary filter cartridges is limited; the height of the filter cartridge cannot be made too high. Therefore, the application scenarios for lug-type and rotary filter cartridges are limited.

[0028] To address the aforementioned problems, this embodiment discloses a drawer-type quick-release filter cartridge structure, the structure of which is as follows: Figures 1 to 3As shown, the quick-release structure includes a bracket 100, a filter cartridge 101, and a movable component 200. The bracket 100 is provided with a through hole 102 for exposing the filter cartridge 101, and the movable component 200 is connected to one side of the filter cartridge 101. A plurality of first arc-shaped grooves 103 are provided on one side of the bracket 100, and a first guide 201 is provided on one side of the movable component 200. The first guide 201 is movably disposed in the first arc-shaped grooves 103. When the first guide 201 moves from one end of the first arc-shaped groove 103 away from the through hole 102 to the other end close to the through hole 102, the opening of the filter cartridge 101 gradually approaches the through hole 102 and finally presses against the bracket 100.

[0029] In this embodiment, the shape of the first arc-shaped groove 103 is preferably a quarter circle, from Figure 1 As can be seen, the direction of the first arc-shaped groove 103 extends from the upper left to the lower right. Therefore, the trajectory of the movable part 200 during the pushing and pulling process also follows the shape of the first arc-shaped groove 103. In addition, the movable part 200 in this embodiment is a structure with two symmetrical arrangements on the left and right. There are multiple first arc-shaped grooves 103, and multiple first arc-shaped grooves 103 are also provided on the movable parts 200 on both sides. The first arc-shaped grooves 103 on both sides of the movable part 200 are symmetrically arranged about the movable part 200, which makes the movement of the movable part 200 more stable.

[0030] In actual use, after the filter cartridge 101 is installed on the movable part 200, the movable part 200 is moved towards the through hole 102, so that the first guide 201 moves upward along the first arc groove 103. When the first guide 201 abuts against the uppermost end of the first arc groove 103, the filter cartridge 101 presses against the bracket 100, which increases the friction between the first guide 201 and the first arc groove 103. Finally, the first guide 201 and the first arc groove 103 are locked together, thus realizing the installation of the filter cartridge 101.

[0031] Specifically, the quick-release structure also includes a handle 202, one end of which is rotatably connected to the end of the movable part 200 near the first arc-shaped groove 103 away from the through hole 102.

[0032] Furthermore, the handle 202 and the movable part 200 are connected by a connecting plate 203. One end of the connecting plate 203 is rotatably connected to the end of the movable part 200 near the handle 202 and the end of the bracket 100 near the handle 202. The other end of the connecting plate 203 is provided with a second arc-shaped groove 204, a first straight groove 205 communicating with the second arc-shaped groove 204, and a second straight groove 206 collinearly arranged with the first straight groove 205. The length direction of the first straight groove 205 is parallel to the length direction of the connecting plate 203. One end of the handle 202 is provided with a second guide 207 and a third guide 208. The second guide 207 is movably disposed in the second arc-shaped groove 204 and the first straight groove 205, and the third guide 208 is movably disposed in the second straight groove 206.

[0033] Under normal circumstances, the movable part 200 is located at the bottom. At this time, the positions of the movable part 200, the connecting plate 203, and the handle 202 are as follows: Figure 2 As shown, the second guide 207 is located at the outermost end of the first straight groove 205, and the third guide 208 is located at the outermost end of the second straight groove 206. If the user grabs the handle 202 and pulls it upward, the second guide 207 and the third guide 208 move downward simultaneously. When the third guide 208 abuts against the other end of the second straight groove 206, the second guide 207 is just at the connection between the first straight groove 205 and the second arc-shaped groove 204. At this time, the third guide 208 abuts against the second straight groove 206 and rotates, while the second guide 207 continues to move along the second arc-shaped groove 204. After the second guide 207 abuts against the other end of the second arc-shaped groove 204, pulling the handle 202 upward will lift the connecting plate 203 upward along the first arc-shaped groove 103. Finally, the filter cartridge 101 presses against the bracket 100, completing the installation of the filter cartridge 101. At this time, the positions of the moving part 200, the connecting plate 203, and the handle 202 are as follows: Figure 3 As shown, the disassembly of the filter cartridge 101 is the reverse of the above steps, and will not be described again here. By setting the handle 202 and the connecting plate 203, the disassembly and assembly can be made easier.

[0034] Furthermore, the bracket 100 is provided with a first guide groove 209 at one end near the connecting plate 203, and the movable member 200 is provided with a second guide groove 210 at one end near the connecting plate 203. Both the first guide groove 209 and the second guide groove 210 are open on the outside. The opening direction of the first guide groove 209 is parallel to the length direction of the movable member 200, and the opening direction of the first guide groove 209 intersects perpendicularly with the opening direction of the second guide groove 210. The movable member 200 is also provided with a fourth guide member 211 at one end near the connecting plate 203. A fifth guide member 214 is also provided at one end of the plate 203. The movable member 200 is rotatably connected to the connecting plate 203 through the fourth guide member 211. The bracket 100 is rotatably connected to the connecting plate 203 through the fifth guide member 214. When the movable member 200 moves toward the through hole 102, the fifth guide member 214 disengages from the second guide groove 210 while the fourth guide member 211 extends into the first guide groove 209. When the movable member 200 moves away from the through hole 102, the fourth guide member 211 disengages from the first guide groove 209 while the fifth guide member 214 extends into the second guide groove 210.

[0035] In this embodiment, the first guide groove 209 and the second guide groove 210 serve the functions of guiding and stabilizing, respectively, from... Figure 2 It can be seen that when the movable part 200 is at its bottom position, the fourth guide 211 is disengaged from the first guide groove 209 and suspended in the air, and the fifth guide 214 is located at the innermost end of the second guide groove 210. During the process of pulling the handle 202 upward, the fifth guide 214 will move out from the opening of the second guide groove 210. During this process, the fifth guide 214 will be suspended in the air, and the fourth guide 211 will enter the first guide groove 209 from the opening of the first guide groove 209. When the filter cartridge 101 presses against the bracket 100, the fourth guide 211 will finally press against the bottom end of the first guide groove 209. By setting the second guide groove 210, the fifth guide 214 can be moved aside when rotating, and the rotation of the connecting plate 203 can be ensured to be stable. The fourth guide 211 and the first guide groove 209 can increase the friction between the bracket 100 and the movable part 200, and improve the stability of the filter cartridge 101 installation.

[0036] Specifically, the movable component 200 is provided with a slide rail 212, and the upper end of the filter cartridge 101 is disposed in contact with the slide rail 212, from which... Figure 1 It can be seen that the two slide rails 212 are symmetrically arranged on both sides of the movable part 200, and two filter cartridges 101 can be placed on a pair of slide rails 212 at the same time; and a limiting member 213 is provided at one end of the slide rail 212, which can limit the placement of the filter cartridge 101 and reduce the difficulty of accurately placing the filter cartridge 101.

[0037] It should be noted that in this embodiment, the handle 202, connecting plate 203 and other structures are symmetrically arranged on both sides of the movable part 200 to improve the stability of the filter cartridge 101 during installation; and multiple movable parts 200 and other structures can be extended at the bracket 100 to realize the installation of multiple filter cartridges 101. The above structures and principles will not be described in detail.

[0038] In summary, the drawer-type quick-release filter cartridge structure of this embodiment achieves quick assembly and disassembly of the filter cartridge 101 by pushing and pulling, thereby enabling the first arc groove 103 on the bracket 100 to cooperate with the first guide member 201 on the movable member 200, while ensuring the airtightness between the filter cartridge 101 and the bracket 100, thus making it more versatile.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention 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 solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
