Description

Technical Field

[0001] The utility model relates to the technical field of filter cartridges, in particular to a high-strength composite polyester filter cartridge. Background Art

[0002] There are various dust removal devices for purifying dust-laden airflows. The bag filter and the cartridge filter, which are simple in structure and have immediate dust removal effects, are the most common. A polyester filter cartridge can be made by pleating and shaping a polyester filter cloth.

[0003] Regarding the above related technologies, the inventor believes that there are the following defects: When the existing filter cartridges are used, screws are mostly used to fix the filter cartridges. In this process, when the space for installing the filter cartridges is relatively narrow, using screws for fixation is time-consuming and laborious for the staff during the installation process, thereby increasing the working difficulty of the staff. Summary of the Utility Model

[0004] In order to solve the above problems, the utility model provides a high-strength composite polyester filter cartridge.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A high-strength composite polyester filter cartridge includes a filter cartridge body. Two symmetrically arranged fixing hoops are symmetrically provided on the outer wall of the filter cartridge body. A fixing ring is fixedly provided on the upper surface of the filter cartridge body. A fixing plate is installed at the upper end of the fixing ring. A plurality of sliding grooves are formed on the bottom surface of the fixing plate. Fixing grooves are formed on the inner walls of the sliding grooves. A sliding rod is slidably arranged in the sliding grooves. A blocking groove is formed on the side wall of the sliding rod and is opposite to the fixing groove. A fixing block is slidably arranged in the fixing groove. The fixing block is slidably connected with the blocking groove. The sliding rod is fixedly connected with the fixing ring.

[0006] By adopting the above technical solutions, when the staff needs to use the filter cartridge body, the staff needs to align the sliding rod with the sliding groove. Subsequently, the staff moves the filter cartridge body in the direction close to the fixing cylinder, so that the fixing ring moves in the direction close to the fixing cylinder under the action of the filter cartridge body, and thus the sliding rod slides in the direction close to the fixing cylinder under the action of the fixing ring. During this process, the staff needs to slide the fixing block into the fixing groove. Subsequently, when the fixing groove is opposite to the blocking groove, the staff needs to slide the fixing block in the direction close to the blocking groove, so that one end of the fixing block slides into the blocking groove, thereby fixing the sliding rod by the fixing block, and further fixing the fixing ring and the fixing cylinder. During this process, the staff only needs to slide the filter cartridge body to complete the installation, thereby reducing the working difficulty of the staff.

[0007] Further, a first spring is fixedly arranged on the side wall of the fixed block, the other end of the first spring is fixedly arranged on the inner wall of the fixed groove, and a first inclined surface is formed on the edge where the side wall of the fixed block away from the first spring intersects with the side wall close to the filter cartridge body.

[0008] By adopting the above technical solution, when the sliding rod slides downward in the direction close to the fixed cylinder under the action of the fixed ring, the sliding rod gradually approaches and finally abuts against the first inclined surface, so that the fixed block slides into the fixed groove under the action of the sliding rod. Subsequently, when the fixed groove is aligned with the blocking groove, one end of the fixed block slides into the blocking groove under the action of the first spring. In this process, the staff does not need to manually slide the fixed block, thereby reducing the working difficulty of the staff.

[0009] Further, a limiting groove is formed on the side wall of the fixed block close to the first spring, a limiting rod is fixedly arranged on the inner wall of the fixed groove, the limiting rod is matched with the limiting groove, and the limiting rod is made of rubber.

[0010] By adopting the above technical solution, when the staff needs to disassemble the filter cartridge body, the staff needs to continue to move the filter cartridge body in the direction close to the fixed cylinder, so that the fixed block is pushed into the fixed groove under the action of the first inclined surface. Subsequently, the staff moves the filter cartridge body in the direction away from the fixed part, and the disassembly can be completed. In this process, the limiting rod and the limiting groove slide relatively. Since the limiting rod is made of rubber and rubber has good elasticity, the limiting rod made of rubber increases the upper limit of the maximum static friction force between the limiting rod and the limiting groove, thereby reducing the probability of the fixed block sliding into the blocking groove for the second time, and thus improving the stability of the device.

[0011] Further, the diameter of the end of the limiting rod close to the fixed block is smaller than the diameter of the end of the limiting rod away from the fixed block.

[0012] By adopting the above technical solution, the diameter of the end of the limiting rod close to the fixed block being smaller than the diameter of the end of the limiting rod away from the fixed block reduces the difficulty of the relative sliding between the limiting rod and the limiting groove, thereby reducing the working difficulty of the staff.

[0013] Further, internal threads are arranged on the inner wall of the fixed disk, external threads are fixedly arranged on the outer wall of the fixed ring, and the internal threads are matched with the external threads.

[0014] By adopting the above technical solution, when the staff needs to install the filter cartridge body, the staff needs to align the fixed ring with the fixed cylinder. Subsequently, the staff only needs to rotate the filter cartridge body, so that the internal threads and the external threads are meshed with each other, and thus the installation of the filter cartridge body is completed. In this process, the staff only needs to rotate the filter cartridge body to complete the installation, thereby reducing the working difficulty of the staff.

[0015] Furthermore, a plurality of L-shaped grooves are formed in the side wall of the fixed disk close to the fixed ring, a plurality of mounting blocks are fixedly arranged on the side wall of the fixed ring, the mounting blocks are slidably connected with the L-shaped grooves, and the mounting blocks are rotatably connected with the L-shaped grooves.

[0016] By adopting the above technical solution, when the filter cartridge body needs to be installed during work, the staff needs to align the mounting block with the L-shaped groove. Subsequently, the staff moves the filter cartridge body, so that the mounting block slides under the action of the filter cartridge body, and then the side wall of the mounting block abuts against the inner wall of the L-shaped groove. At this time, the staff rotates the filter cartridge body, so that the mounting block rotates under the action of the filter cartridge body, thus completing the installation of the filter cartridge body, and further reducing the work difficulty of the staff.

[0017] Furthermore, a chamfer is formed on the side wall of the mounting block.

[0018] By adopting the above technical solution, the chamfer reduces the difficulty for the staff to slide the mounting block into the L-shaped groove, thereby reducing the work difficulty of the staff.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. In this application, when the staff needs to use the filter cartridge body, the staff needs to align the sliding rod with the sliding groove. Subsequently, the staff moves the filter cartridge body towards the fixed cylinder, so that the fixed ring moves towards the fixed cylinder under the action of the filter cartridge body, and then the sliding rod slides towards the fixed cylinder under the action of the fixed ring. During this process, the staff needs to slide the fixed block into the fixed groove. Subsequently, when the fixed groove is aligned with the blocking groove, the staff needs to slide the fixed block towards the blocking groove, so that one end of the fixed block slides into the blocking groove, thereby fixing the sliding rod by the fixed block, and further fixing the fixed ring and the fixed cylinder. During this process, the staff only needs to slide the filter cartridge body to complete the installation, thereby reducing the work difficulty of the staff;

[0021] 2. In this application, when the sliding rod slides towards the fixed cylinder under the action of the fixed ring, the sliding rod gradually approaches and finally abuts against the first inclined surface, so that the fixed block slides into the fixed groove under the action of the sliding rod. Subsequently, when the fixed groove is aligned with the blocking groove, one end of the fixed block slides into the blocking groove under the action of the first spring. During this process, the staff does not need to manually slide the fixed block, thereby reducing the work difficulty of the staff;

[0022] 3. In this application, when the staff needs to disassemble the filter cartridge body, the staff needs to continue to move the filter cartridge body in the direction closer to the fixed cylinder, so that the fixing block is pushed into the fixing groove under the action of the first inclined surface. Subsequently, the staff moves the filter cartridge body in the direction away from the fixing, and the disassembly can be completed. During this process, the limiting rod and the limiting groove slide relative to each other. Since the limiting rod is made of rubber and rubber has good elasticity, the limiting rod made of rubber increases the upper limit of the maximum static friction force between the limiting rod and the limiting groove, thereby reducing the probability of the fixing block sliding into the blocking groove again, and thus improving the stability of the device.

Detailed Embodiment

[0030] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0031] Embodiment 1

[0032] As Figures 1-3As shown in the figure, an embodiment of the present application discloses a high-strength composite polyester filter cartridge, which includes a filter cartridge body 1, a fixing hoop 11, a fixing ring 12, a fixing disk 13, a fixing block 31, a first spring 4, and a limiting rod 5. The axis of the filter cartridge body is vertical. There are two fixing hoops 11, which are symmetrically arranged on the outer wall of the filter cartridge body, and their axes coincide with the axis of the filter cartridge body. The fixing ring 12 is in a circular ring structure, and its axis coincides with the axis of the filter cartridge body. The fixing ring 12 is fixedly arranged on the upper surface of the filter cartridge body 1. The fixing disk 13 is installed at the upper end of the fixing ring 12, and its axis coincides with the axis of the filter cartridge body. A plurality of sliding grooves 2 are formed on the bottom surface of the fixing disk 13, and fixing grooves 21 are formed on the inner walls of the sliding grooves 2. The sliding rod 3 is in a rectangular rod shape and is slidably arranged in the sliding groove 2. A blocking groove 22 is formed on the side wall of the sliding rod 3 opposite to the fixing groove 21, and the sliding rod 3 is fixedly connected to the fixing ring 12. The fixing block 31 is in a rectangular block shape and is slidably arranged in the fixing groove 21, and the fixing block 31 is slidably connected to the blocking groove 22.

[0033] When the staff needs to use the filter cartridge body 1, the staff needs to align the sliding rod 3 with the sliding groove 2. Subsequently, the staff moves the filter cartridge body in the direction close to the fixing cylinder, so that the fixing ring 12 moves in the direction close to the fixing cylinder under the action of the filter cartridge body, and then the sliding rod 3 slides in the direction close to the fixing cylinder under the action of the fixing ring 12. During this process, the staff needs to slide the fixing block 31 into the fixing groove 21. Subsequently, when the fixing groove 21 is aligned with the blocking groove 22, the staff needs to slide the fixing block 31 in the direction close to the blocking groove 22, so that one end of the fixing block 31 slides into the blocking groove 22, thereby fixing the sliding rod 3 by the fixing block 31, and then fixing the fixing ring 12 to the fixing cylinder. During this process, the staff only needs to slide the filter cartridge body to complete the installation, thereby reducing the work difficulty of the staff.

[0034] One end of the first spring 4 is fixedly arranged on the side wall of the fixing block 31, and the other end of the first spring 4 is fixedly arranged on the inner wall of the fixing groove 21. A first inclined surface 41 is formed on the edge where the side wall of the fixing block 31 far from the first spring 4 intersects with its side wall close to the filter cartridge body 1.

[0035] When the sliding rod 3 slides in the direction close to the fixing cylinder under the action of the fixing ring 12, the sliding rod 3 gradually approaches and finally abuts against the first inclined surface 41, so that the fixing block 31 slides into the fixing groove 21 under the action of the sliding rod 3. Subsequently, when the fixing groove 21 is aligned with the blocking groove 22, one end of the fixing block 31 slides into the blocking groove 22 under the action of the first spring 4. During this process, the staff does not need to manually slide the fixing block 31, thereby reducing the work difficulty of the staff.

[0036] A limiting groove 23 is formed in the side wall of the fixed block 31 close to the first spring 4. The limiting rod 5 is fixedly arranged on the inner wall of the fixed groove 21. The limiting rod 5 and the limiting groove 23 are matched with each other, and the limiting rod 5 is made of rubber.

[0037] When the staff needs to disassemble the filter cartridge main body, the staff needs to continue to move the filter cartridge main body in the direction close to the fixed cylinder, so that the fixed block 31 is pushed into the fixed groove 21 under the action of the first inclined surface 41. Subsequently, the staff moves the filter cartridge main body in the direction away from the fixed part, and the disassembly can be completed. During this process, the limiting rod 5 and the limiting groove 23 slide relatively. Since the limiting rod 5 is made of rubber and rubber has good elasticity, the limiting rod 5 made of rubber increases the upper limit of the maximum static friction force between the limiting rod 5 and the limiting groove 23, thereby reducing the probability of the fixed block 31 sliding into the blocking groove 22 again, thus improving the stability of the device.

[0038] In order to reduce the working difficulty of the staff, the diameter of the end of the limiting rod 5 close to the fixed block 31 is smaller than the diameter of the end of the limiting rod 5 far from the fixed block 31. The diameter of the end of the limiting rod 5 close to the fixed block 31 being smaller than the diameter of the end of the limiting rod 5 far from the fixed block 31 reduces the difficulty of the relative sliding between the limiting rod 5 and the limiting groove 23, thereby reducing the working difficulty of the staff.

[0039] The working principle of a high-strength composite polyester filter cartridge in this embodiment is as follows: When the staff needs to use the filter cartridge body 1, the staff needs to align the sliding rod 3 with the sliding groove 2. Subsequently, the staff moves the filter cartridge main body in the direction close to the fixed cylinder, so that the fixed ring 12 moves in the direction close to the fixed cylinder under the action of the filter cartridge main body, and thus the sliding rod 3 slides in the direction close to the fixed cylinder under the action of the fixed ring 12. During this process, the sliding rod 3 gradually approaches and finally abuts against the first inclined surface 41, so that the fixed block 31 slides into the fixed groove 21 under the action of the sliding rod 3. Subsequently, when the fixed groove 21 is aligned with the blocking groove 22, one end of the fixed block 31 slides into the blocking groove 22 under the action of the first spring 4, so that the fixed block 31 fixes the sliding rod 3, and thus the fixed ring 12 and the fixed cylinder are fixed to each other. During this process, the staff only needs to slide the filter cartridge main body to complete the installation, thereby reducing the working difficulty of the staff.

[0040] Embodiment 2

[0041] As Figure 4The difference between this embodiment and Embodiment 1 lies only in the different ways of installing the filter cartridge body. When installing the filter cartridge body in this embodiment: The staff needs to align the fixing ring 12 with the fixing cylinder. Subsequently, the staff can rotate the filter cartridge body, so that the internal thread 6 meshes with the external thread 61, thereby completing the installation of the filter cartridge body. In this process, the staff only needs to rotate the filter cartridge body to complete the installation, thus reducing the work difficulty of the staff.

[0042] Embodiment 3

[0043] As Figures 5-6 The difference between this embodiment and Embodiment 1 lies only in the different ways of installing the filter cartridge body. When installing the filter cartridge body in this embodiment: When the work needs to install the filter cartridge body, the staff needs to align the installation block 7 with the L-shaped groove 24. Subsequently, the staff moves the filter cartridge body, so that the installation block 7 slides under the action of the filter cartridge body, and then the side wall of the installation block 7 abuts against the inner wall of the L-shaped groove 24. At this time, the staff rotates the filter cartridge body, so that the installation block 7 rotates under the action of the filter cartridge body, thereby completing the installation of the filter cartridge body, and then reducing the work difficulty of the staff. In this process, the chamfer 8 reduces the difficulty for the staff to slide the installation block 7 into the L-shaped groove 24, thereby reducing the work difficulty of the staff.

[0044] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications should also be regarded as the protection scope of the present invention.
