Description

Technical Field

[0001] This utility model relates to the field of filter element protection technology, and in particular to a protective structure for composite bending of filter elements. Background Technology

[0002] The filter element is the core component of a filter, and its performance directly affects the filtration efficiency and service life. To improve the filter's performance and adaptability, some filters use filter elements with bends. However, traditional bend-type filter elements are prone to damage due to stress concentration at the bends, leading to decreased filtration efficiency or even failure. Furthermore, the bends are easily damaged by impacts; therefore, protective structures are needed at the bends of the filter element.

[0003] Traditional filter element bending protection structures use a support frame with a metal mesh. However, the metal mesh is easily deformed under external force, exerting force on the filter element bending point. Therefore, the protection effect on the filter element bending point is generally poor. At the same time, the support frame is fixedly connected to the metal mesh and cannot be adjusted according to the actual situation, resulting in poor flexibility and adaptability in use, and the overall effect is generally poor.

[0018] like Figures 1-4 As shown, a protective structure for composite bending of filter element includes a filter element body 1, the middle section of the filter element body 1 is bent at ninety degrees to form an L-shaped structure, and the two ends of the filter element body 1 are fixed with connecting end plates 2, the connecting end plates 2 are fixed with filter element plug connectors 3, and a protective structure 4 is provided at the L-shaped structure in the middle section of the filter element body 1.

[0019] When installing and using the filter element, connect the connecting end plate 2 at the end of the filter element body 1 to the mounting structure inside the filter. Insert the filter element connector 3 into the mounting structure. After installation, install the protective structure 4 on the bent portion of the filter element body 1, and then begin use. During use, the filter element body 1 performs filtration. The protective structure 4 protects the bent portion of the filter element body 1, ensuring high strength and preventing damage due to stress concentration. It also prevents external forces from acting on the bent portion, ensuring its integrity.

[0020] According to the above implementation scheme, the protective structure 4 includes an installation component 401, a protective bending rod 402, and a support component 403. The installation component 401 is disposed on the filter element body 1. The end of the protective bending rod 402 passes through the installation component 401, and the middle section of the protective bending rod 402 is bent at ninety degrees to form an L-shaped protective rod. The support component 403 is installed at the end of the protective bending rod 402, and the support component 403 contacts the outer surface of the filter element body 1.

[0021] When installing the protective structure 4, the end of the protective bending rod 402 passes through the mounting assembly 401, and a support assembly 403 is set at the end of the protective bending rod 402. Then, the mounting assembly 401 is set onto the filter element body 1, and the support assembly 403 contacts the filter element body 1 to provide support. In use, the protective bending rod 402 protects the bent part of the filter element body 1, ensuring the integrity of the bent part and guaranteeing the filtration effect of the entire filter, while reducing the cost of use.

[0022] The mounting assembly 401 includes a first mounting plate 4011 and a second mounting plate 4012. The first mounting plate 4011 and the second mounting plate 4012 are provided with semi-circular holes, and the first mounting plate 4011 and the second mounting plate 4012 are mounted on the filter element body 1 through the semi-circular holes, forming a complete annular mounting plate.

[0023] Mounting assembly 401 also includes a connecting screw hole 4013, a countersunk hole 4014, a countersunk bolt 4015, and a through hole 4016. The connecting screw hole 4013 is formed on the first mounting plate 4011, the countersunk hole 4014 is formed on the second mounting plate 4012, and the countersunk hole 4014 is aligned with the connecting screw hole 4013. The countersunk bolt 4015 is located in the countersunk hole 4014 on the second mounting plate 4012, and the end of the countersunk bolt 4015 is connected to the second mounting plate 4012 on the first mounting plate 4011. The through hole 4016 is formed on the first mounting plate 4011 and the second mounting plate 4012.

[0024] When installing the entire protective structure 4, after the end of the protective bent rod 402 passes through the through hole 4016, the first mounting plate 4011 and the second mounting plate 4012 are fitted onto the filter element body 1 to form a complete annular mounting plate. Then, the countersunk bolt 4015 is placed in the countersunk hole 4014, so that the end of the countersunk bolt 4015 is screwed into the connecting screw hole 4013, thereby fixing the mounting plate. At this time, the two sets of mounting components 401 are set at a ninety-degree angle, and the protective bent rod 402 is limited on the mounting components 401, preventing wobbling and ensuring operational stability.

[0025] The support assembly 403 includes a support block 4031, a connecting hole 4032, and a clamping screw 4033. The connecting hole 4032 is formed on the support block 4031, and the support block 4031 is disposed at the end of the protective bend rod 402 through the connecting hole 4032.

[0026] When installing the support assembly 403, the support block 4031 is set to the end of the protective bend 402 through the connecting round hole 4032, and is tightened and fixed by the tightening screw 4033. After the entire protective structure 4 is installed, the support block 4031 contacts the outer surface of the filter element body 1, providing support for the protective bend 402 and ensuring the stability of the protective bend 402.

[0027] It should be noted that the protective structure 4, with the protective bending rod 402, effectively protects the bent portion of the filter element body 1, preventing damage to the bent portion from external forces. Simultaneously, the protective bending rod 402, in conjunction with the mounting assembly 401, provides support, increasing the strength of the bent portion of the filter element body 1, preventing damage due to stress concentration, extending the service life of the filter element body 1, and ensuring filtration efficiency. The end of the protective bending rod 402 is directly inserted into the mounting assembly 401, allowing for quick assembly and disassembly with high ease of operation. A support assembly 403 is provided at the end of the protective bending rod 402, providing support and increasing its stability, further enhancing the protective effect and effectively protecting the bent portion of the filter element body 1. The mounting assembly 401 includes a first mounting plate 4011 and a second mounting plate 4012, allowing for quick assembly and disassembly of the entire protective structure 4 and facilitating the replacement of the protective bending rod 402.
