Description
Technical Field
[0001] This application relates to the field of filter element technology, and in particular to a filter element that is easy to install. Background Technology
[0002] In industrial dust collectors and pulse jet dust collectors, filter elements are one of the key components, used to filter dust and other particulate matter from the air to ensure the cleanliness of the production environment and product quality. With the continuous development of industrial production, the demand for filter elements is constantly increasing, especially for high-efficiency, reliable, and easy-to-maintain filter elements. While traditional filter element designs can meet basic filtration requirements, they present many inconveniences in practical applications, particularly during installation and maintenance.
[0003] Currently, the common practice for installing filter cartridges is to insert a screw through the center of the dust collector and then tighten a nut onto the screw. This installation method requires multiple people and various tools, making it not only complex but also time-consuming and labor-intensive. Furthermore, the need for repeated adjustments and tightening during installation can easily lead to poor sealing between the filter cartridge and the dust collector, thus affecting filtration efficiency. In addition, frequent disassembly and reassembly accelerate filter cartridge wear and shorten its lifespan. Utility Model Content
[0004] The purpose of this application is to overcome the above-mentioned technical problems and provide a filter element that is easy to install.
[0005] An easy-to-install filter element, comprising:
[0006] The filter element body includes a support frame and a filter media cylinder sleeved on the outer peripheral surface of the support frame;
[0007] The lower end assembly includes a mounting ring and a connecting ring coaxially connected. The connecting ring is sleeved on the outer circumferential surface of the mounting ring. The mounting ring includes a protrusion extending from the connecting ring, and the protrusion has an internal thread. The end of the connecting ring opposite to the protrusion is fixed to the first end of the filter element body.
[0008] The upper end assembly is connected to the end of the filter cartridge body opposite to the lower end assembly. The upper end assembly includes a handle and a connecting plate. The handle is detachably connected to the middle of the connecting plate. The connecting plate covers the end of the filter cartridge. The handle supports the frame for fixation.
[0009] By adopting the above method, during the process of installing the filter element into the dust collector, the worker can mate the internal thread of the installation ring with the dust collector, hold the filter element body with one hand, and rotate the knob with the other hand to fix the filter element to the dust collector.
[0010] In one embodiment, the mounting ring is provided with a sealing ring located on the top surface of the threaded interface.
[0011] By adopting the above solution, the sealing between the filter element and the dust collector is improved, preventing pollutants from flowing through the gaps and improving the filtration effect of the filter element.
[0012] In one embodiment, both the connecting ring and the connecting disc are provided with limiting blocks. The filter cartridge connecting disc, which is easy to install, also includes limiting blocks. The limiting blocks are distributed in a circumferential array at the end of the filter media cylinder and are in contact with the pleated surface of the filter media cylinder.
[0013] By adopting the above scheme, the two adjacent limiting blocks limit the pleats of the filter media cylinder, preventing relative displacement between the filter media cylinder and the upper and lower end components, which would cause the filter media cylinder to fall off the end cap and thus affect the filtration effect of the filter element.
[0014] In one embodiment, both the connecting ring and the connecting disc are provided with glue-holding grooves inside, and both the connecting ring and the connecting disc are provided with glue-injection ports communicating with the glue-holding grooves on their outer peripheral surfaces. The connection points between the connecting ring and the connecting disc and the filter element body are provided with glue-out holes communicating with the glue-holding grooves.
[0015] By adopting the above solution, when the filter media cylinder, the upper end assembly, and the lower end assembly become loose, glue can be filled into the glue tank from the glue injection port. The glue then flows into the contact surface between the connecting ring and the connecting disc and the filter element through the glue outlet, thereby achieving a reinforcement effect.
[0016] In one embodiment, the limiting block is hollow and its interior is connected to the glue-dispensing groove, and the glue outlet is located at the contact surface between the limiting block and the filter cylinder.
[0017] By adopting the above scheme, when the glue is filled from the glue injection port, the glue flows from the glue placement groove into the cavity inside the limiting block, and finally flows into the space between the limiting block and the filter cylinder, making the glue filling area larger and the reinforcement effect better.
[0018] In one embodiment, the outer peripheral surface of the support frame has a porous structure.
[0019] By adopting the above solution, the support frame can not only support the filter material but also perform the filtering effect, thereby enhancing the filtration efficiency of the filter element.
[0020] In one embodiment, a dust removal component is provided between the support frame and the filter media cylinder. One end of the dust removal component is fixed to the mounting ring. When the mounting ring rotates, it can drive the dust removal component to move along the outer circumference of the support frame.
[0021] By adopting the above solution, when the mounting ring rotates, it can drive the dust removal component to sweep over the support frame and filter media. The dust removal component can remove the dust between the support frame and the filter media. When replacing the mounting ring, the dust removal component can be taken out for cleaning, thus extending the service life of the filter element.
[0022] In one embodiment, the dust removal component includes a dust removal sleeve and a connecting rod. The connecting rod is fixedly connected to the mounting ring, and the dust removal sleeve is sleeved on the connecting rod. Dust removal blocks are distributed in a circumferential array on the outer circumferential surface of the dust removal sleeve.
[0023] By adopting the above solution, when the connecting rod drives the dust removal sleeve to move, the dust removal block collides and rubs with the filter cylinder and the support frame, thereby removing the dust from the filter cylinder and the support frame.
[0024] In one embodiment, the dust removal sleeve is rotatably connected to the connecting rod, and the surface of the dust removal block is provided with dust removal felt.
[0025] By adopting the above solution, the contact between the dust removal block and the dust removal sleeve is made gentler, avoiding hard contact between the dust removal sleeve and the filter media, which would lead to excessive friction and damage to the filter media.
[0026] In one embodiment, the dust removal components include multiple components and are arranged in a circumferential array on the edge of the mounting ring.
[0027] By adopting the above scheme, the angle of rotation required for the mounting ring to drive the dust removal component to sweep across the entire outer circumference of the support frame is reduced, while the dust removal efficiency of the dust removal component is increased.
[0028] In summary, this application includes at least one of the following beneficial technical effects:
[0029] 1. Due to the relatively long length of the screw inside the dust collector, during the installation of the filter element, it is necessary to pass the screw through the limiting hole at the end of the filter element. One person needs to hold the filter element to limit its position, ensuring the screw aligns with the limiting hole at the end of the filter element. After the screw passes through the limiting hole, another person holds the nut with one hand and uses a tool with the other to fit the nut onto the part of the screw protruding from the limiting hole, tightening the nut to fix the filter element to the dust collector. This process requires multiple people to work together. This application addresses this by setting an installation ring on the lower end assembly that mates with the threads of the dust collector, and a tightening handle on the upper end assembly. During filter element installation, only one hand needs to hold the filter element, aligning the internal thread of the installation ring with the external thread of the dust collector, while the other hand rotates the tightening handle to tighten the installation ring to the dust collector, thus fixing the installation ring to the dust collector and completing the filter element installation. This allows the installation of the filter element and filter to be completed by only one person.
[0030] 2. During use, the end cap and filter element body are prone to delamination, which reduces the filter element's sealing performance. By setting a limiting block and a glue inlet on the end cap, the filter media cylinder is further prevented from deforming and shifting from the end, thus preventing delamination. When the filter media cylinder delaminates from the end cap, the limiting block clamps the pleated surface of the filter media cylinder, so the filter media cylinder will not fall off immediately. Since there is a glue injection port on the contact surface between the limiting block and the filter media cylinder, glue is injected through the glue injection port. The glue fills the contact surface between the limiting block and the filter media cylinder, making the connection between the filter media cylinder and the end cap more secure.
[0031] 3. Since the filter cartridge needs to be replaced with a new one after accumulating too much dust and pollutants, resulting in material loss, a dust collector is installed between the support frame and the filter cartridge. The dust collector is connected to the mounting ring. When the mounting ring rotates, it can drive the dust collector to sweep across the support frame and the filter cartridge. The dust removal blocks on the dust collector collide and rub against the filter cartridge and the support frame, which can remove the dust between the support frame and the filter cartridge. The dust collector can be removed and cleaned at the same time as the mounting ring is replaced, thus extending the service life of the filter cartridge. Attached Figure Description

[0040] Therefore, it is necessary to provide a filter element that is easy to install with a dust collector.
[0041] Please see Figure 1 , Figure 1 The first embodiment of this application provides a schematic diagram of a filter element structure that is easy to install, including: a lower end assembly 1, a filter element body 2, and an upper end assembly 3.
[0042] Please refer to the following: Figure 2 , Figure 2 This is an exploded view of an easily installed filter element according to the first embodiment of this application. The upper end assembly 3 is used for the installation connection between the filter element and the dust collector. The upper end assembly 3 includes a mounting ring 11 and a connecting ring 12. The connecting ring 12 is sleeved on the outer circumferential surface of the mounting ring 11, and the connecting ring 12 and the mounting ring 11 are threaded together. The mounting ring 11 includes a protrusion 13 protruding from the connecting ring 12. The protrusion 13 of the mounting ring 11 has a thread that mates with the dust collector. This thread can be an internal thread or an external thread located on the outer circumferential surface of the portion of the mounting ring 11 protruding from the connecting ring 12. A sealing ring 111 is provided on the top surface of the threaded interface to seal between the filter element and the dust collector. When the thread of the mounting ring 11 mates with the dust collector is an external thread, the protrusion 13 of the mounting ring 11 is prismatic. The operator can use a wrench or other tools to clamp the side of the prismatic shape, thereby facilitating rotation and enabling the installation or removal of the mounting ring 11 and the connecting ring 12. The operator can replace different models of the mounting ring 11 to mate with different models of equipment.
[0043] The filter element body 2 is fixedly connected to the mounting ring 11 with glue. The filter element body 2 includes a support frame 21 and a filter media cylinder 22. The filter media cylinder 22 is pleated and sleeved on the support frame 21. The filter media cylinder 22 is made of organic fiber, which has good mechanical strength and chemical resistance, and is used to adsorb dust. The outer peripheral surface of the support frame 21 has a porous structure and is made of stainless steel. It supports the filter media cylinder 22. When pollutants pass through the filter media cylinder 22, the support frame 21 can also capture pollutant particles, so that the filter element has a dual filtration structure and enhances the filtration effect of the filter element.
[0044] The upper end assembly 3 is fixedly connected to the end of the filter body 2 that is away from the lower end assembly 1. The upper end assembly 3 includes a handle 31 and a connecting plate 32. The connecting plate 32 is fixed to the support frame 21 by welding. The handle 31 is located in the middle of the connecting plate 32. The handle 31 is provided with a screw handle 311. The screw handle 311 can be plum blossom shaped or multi-faceted. The operator can rotate the entire filter element by rotating the screw handle 311.
[0045] The working principle of this embodiment is as follows: Due to the long length of the filter element and the screw inside the dust collector, during the installation of the filter element into the dust collector, the screw needs to be threaded through the filter element. One person needs to hold the filter element to limit its position and align it with the screw, while another person holds the nut with one hand and tightens the nut with the other using a tool. This process requires the cooperation of multiple people. By setting an installation ring 11 on the lower end assembly 1 that is threaded with the dust collector, and replacing the installation ring 11 with one that is compatible with the filter before use, during the installation of the filter element, only one hand needs to hold the filter element, and the other hand needs to turn the screw handle 311 to rotate the entire filter element. The installation ring 11 is fixed to the filter by the thread, thus completing the installation of the filter element. This allows the installation of the filter element and the filter to be completed by only one person.
[0046] Example 2
[0047] Please see Figure 3-6 , Figure 3 This is a schematic diagram of a filter element structure that is easy to install according to the second embodiment of this application. The filter element provided in the second embodiment is basically the same as the structure of the first embodiment. The difference is that both the connecting ring 12 and the connecting plate 32 are provided with limiting blocks 4. The limiting blocks 4 are hollow structures and are distributed in a circular array on the surfaces of the connecting ring 12 and the filter element body 2 opposite to each other. The pleated surfaces of the filter media cylinder 22 are all in contact with the limiting blocks 4. Both the connecting ring 12 and the connecting plate 32 are provided with glue placement grooves 51 inside and glue injection ports 5 communicating with glue placement grooves 51 on their outer circumferential surfaces. The internal cavity of the limiting blocks 4 is connected to the glue placement grooves 51. The contact surface between the limiting blocks 4 and the pleated surfaces of the filter media cylinder 22 is provided with glue outlet holes 41.
[0048] The working principle is as follows: when the filter media cylinder 22 is subjected to force, the limiting block 4 limits the filter media cylinder 22 to prevent displacement between the filter media cylinder 22 and the end cap. When the filter media cylinder 22 detaches from the upper end assembly 3 and the lower end assembly 1, it will not immediately detach from the end cap because the pleated surface of the filter media cylinder 22 is clamped by the two adjacent limiting blocks 4. Glue is injected from the glue injection port 5, and the glue flows through the glue placement groove 51 and the internal cavity of the limiting block 4. Finally, the glue flows out from the glue outlet holes 41 on both sides of the limiting block 4. The space between the limiting block 4 and the pleated surface of the filter media cylinder 22 is filled with glue. Since the contact area between the limiting block 4 and the pleated surface of the filter media cylinder 22 is large, the glue adhesion is stronger. The limiting block 4 and the filter media cylinder 22 can achieve a stable connection through the glue.
[0049] Please refer to the following: Figure 7 , Figure 7 This is a partial cross-sectional view of the limiting block and filter cylinder in the second embodiment of this application. A dust removal component 6 is provided between the support frame 21 and the filter cylinder 22. The dust removal component 6 includes multiple components arranged in a circumferential array on the edge of the mounting ring 11. The dust removal component 6 includes a dust removal sleeve 62 and a connecting rod 61. The connecting rod 61 is fixedly connected to the mounting ring 11. The dust removal sleeve 62 is sleeved on the connecting rod 61. A bearing 611 is provided between the dust removal sleeve 62 and the connecting rod 61. The dust removal sleeve 62 can rotate around the axis of the connecting rod 61 through the bearing 611. Dust removal blocks 621 are arranged in a circumferential array on the outer circumferential surface of the dust removal sleeve 62. The dust removal blocks 621 are made of soft rubber material to prevent the dust removal blocks 621 from scratching the surface of the filter cylinder 22 during movement. The surface of the dust removal blocks 621 is covered with dust removal felt 6211.
[0050] The working principle of this embodiment is as follows: When the mounting ring 11 is rotated, the mounting ring 11 can drive the connecting rod 61 to rotate along the outer circumference of the support frame 21. The connecting rod 61 drives the dust removal sleeve 62 to move. During the movement of the dust removal sleeve 62, the dust removal block 621 collides and rubs with the filter cylinder 22, thereby removing the dust attached to the filter cylinder 22. The dust removal felt 6211 on the dust removal block 621 can absorb the dust on the filter cylinder 22, while preventing hard contact between the dust removal block 621 and the filter cylinder 22, thus preventing damage to the filter cylinder 22. The user can remove the dust removal component 6 by disassembling the mounting ring 11 to clean it, thereby achieving the effect of multiple uses. By using the dust removal component 6 to remove the dust on the filter cylinder 22, the service life of the filter cylinder 22 can be effectively extended, avoiding repeated replacement of the filter cylinder 22.
[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
