Technical Field
[0001] This utility model relates to the field of corrugated filter technology, and in particular to a corrugated filter. Background Technology
[0002] Filter cartridges are widely used in various liquid filtration systems, such as high-pressure filtration systems. Their main function is to remove impurities from liquids, ensuring liquid purity and thus protecting downstream equipment or guaranteeing product quality. Many existing filter cartridges are prone to deformation or damage under high-pressure environments, especially when the pressure differential is large. The filter cartridge frame is easily bent or cracked, leading to filtration failure, shortened service life, and even system leaks. This limits their use in high-pressure applications. Furthermore, cleaning and maintenance of filter cartridges is usually cumbersome, requiring disassembly and manual cleaning, which is inefficient and easily damages the cartridge. The lack of effective cleaning mechanisms results in incomplete cleaning, and the accumulation of residues affects filtration efficiency and service life.
[0003] Therefore, this application provides a corrugated filter element to meet the requirements. Utility Model Content
[0004] The purpose of this application is to provide a corrugated filter element, which aims to solve the problems that existing filter elements are prone to deformation or damage under high pressure, especially when the pressure difference is large, the filter element skeleton is prone to bending or cracking, resulting in filtration failure and shortened service life. In addition, the cleaning and maintenance of filter elements is usually cumbersome, inefficient and easy to damage the filter element, resulting in incomplete cleaning and residue accumulation that affects filtration efficiency and service life.

A threaded hole that matches the threaded block is opened on the top surface of the inner rod. A locking block is connected to the side wall at both ends of the inner rod. Multiple sets of locking blocks are provided. A limiting groove that matches the locking block is opened on the inner wall of the through hole. A sliding groove for connecting with the lower end cover is opened on the bottom surface of the inner rod, which makes it easier to control the rotation and locking of the support mechanism.

[0010] In summary, the technical effects and advantages of this utility model are as follows:
[0011] In this invention, a 5mm thick seamless perforated stainless steel tube is used as the inner skeleton, and a three-layer corrugated filter material structure (the main filter layer adopts a special easy-to-wash weaving process, and there is a high-strength stainless steel protective mesh on both the inner and outer sides of the main filter layer) is welded to the inner and outer skeletons. In addition, a new support mechanism (including ring plate, column, connecting rod, collar and connecting scraper) is added, which effectively enhances the overall strength and pressure resistance of the filter element. This design can withstand a system pressure of 60Mpa and a pressure difference of 20Mpa, ensuring that the filter element skeleton does not deform under high pressure conditions, significantly extending its service life. The three-layer filter material structure also improves the pressure resistance and toughness of the filter material. Practical verification has shown that the filter material has never cracked, and its service life has increased by nearly three times.
[0012] In this invention, the combination of a locking mechanism and a support mechanism allows for easy control of the rotation and locking of the support mechanism by turning the handle, enabling effective cleaning of the filter element's interior. The cooperation between the ring plate and the connecting scraper helps to clean residues on the inner frame. This design simplifies the cleaning and maintenance process, improves efficiency, avoids filter element damage that may be caused by manual cleaning, and reduces maintenance costs.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0021] refer to Figure 1-5 The corrugated filter element shown includes a frame 2, with an upper end cover 1 and a lower end cover 3 connected to both ends of the frame 2. Both the upper end cover 1 and the lower end cover 3 are provided with water inlets. The frame 2 also includes an inner frame 21 and an outer frame 22. A filter screen 4 for filtering liquid is provided between the inner frame 21 and the outer frame 22. In order to enable the filter element to withstand greater pressure, the inner frame 21 is made of 5mm thick seamless perforated stainless steel tube to ensure that the filter element and the frame 2 do not deform when the system pressure is 60Mpa and the pressure difference between the filter element and the filter element is 20Mpa. A locking mechanism 6 is connected to the lower end cover 3. The lower end cover 3 is locked by the locking mechanism 6 to a support mechanism 5 for increasing the pressure resistance of the filter element.
[0022] As one implementation method in this embodiment, in order to give the filter element better pressure resistance, the skeleton 2 and filter screen 4 are connected to the upper end cover 1 and the lower end cover 3 by welding, which effectively increases the strength. The filter screen 4 of the filter element adopts a three-layer corrugated structure, which increases the filtration area and dirt holding capacity. Compared with the original structure, the service life of the filter element is increased by nearly three times. At the same time, the pressure resistance of the filter material is increased. The three layers of filter material (the main filter layer adopts a special weaving process that is easy to wash, and there is a high-strength stainless steel protective mesh on the inside and outside of the main filter layer) are welded together with the inner skeleton 21 and the outer skeleton 22, which provide strong support to each other. In addition, this structure has better filter material toughness. Under repeated washing of the filter element, years of practice have verified that the filter material has never cracked, effectively improving the pressure resistance and service life of the filter element.
[0023] As one embodiment of this invention, the support mechanism 5 further includes a ring plate 54 and a sleeve rod 55. The sleeve rod 55 is engaged with the lower end cover 3. A guide groove 56 is provided on the sleeve rod 55, and a through hole 57 adapted to the locking mechanism 6 is provided in the sleeve rod 55, so that the locking mechanism 6 can control the rotation and locking of the support mechanism 5. The ring plate 54 is connected to a collar 52 through a connecting rod 53. The inner diameter of the collar 52 is adapted to the size of the sleeve rod 55. The connecting rod 53 slides through the collar 52 in the guide groove 56, so that the column can rotate synchronously when the locking mechanism 6 rotates. There are multiple sets of ring plates 54, and the multiple sets of ring plates 54 are arranged longitudinally at equal intervals. Adjacent ring plates 54 are connected by a connecting scraper 51. The outer diameter of the ring plate 54 is adapted to the inner diameter of the inner frame 21. The ring plate 54 is not only used to assist in supporting the inner frame 21, but also to assist in cleaning the inner frame 21 through the connecting scraper 51.
[0024] As one embodiment of this invention, to make the maintenance and cleaning of the filter element more convenient and quick, the locking mechanism 6 also includes an inner rod 65 and a handle 61. A threaded block 62 is connected to the bottom of the handle 61. A threaded hole 63, matching the threaded block 62, is opened on the top surface of the inner rod 65. Locking blocks 64 are connected to the side walls at both ends of the inner rod 65. The inner rod 65 drives the sleeve rod 55 to rotate synchronously through the locking blocks 64. Multiple sets of locking blocks 64 are provided. A limiting groove 58, matching the locking block 64, is opened on the inner wall of the through hole 57. A connection for connecting to the lower end cover 3 is opened on the bottom surface of the inner rod 65. The sliding groove makes it easier to rotate the inner rod 65 using the handle 61. To make it easier for the locking mechanism 6 to control the locking and rotation of the sleeve rod 55, a support plate 31 is connected to the lower end cover 3. A limit plate 32 and a rotating shaft 33 are connected to the support plate 31. The limit plate 32 has an installation groove 34 that matches the inner rod 65. The rotating shaft 33 is rotatably connected in the installation groove 34. The inner wall of the installation groove 34 has a slot 35 that matches the locking block 64. When the locking block 64 on the inner rod 65 is simultaneously located in the slot 35 and the limit groove 58, the sleeve rod 55 is in a locked state.
[0025] The working principle of this utility model is as follows: When the filter element needs cleaning, first remove the filter element from the filter cartridge of the equipment. Then, use a handheld spray nozzle to clean the surface of the filter element, washing away any residue in the outer frame 22 of the frame 2 and the filter screen 4. Next, rotate the handle 61 through the threaded block 62 into the threaded hole 63 of the inner rod 65. Since both the inner rod 65 and the sleeve rod 55 are in a locked state, the handle 61 can easily rotate the threaded block 62 into the threaded hole 63. Then, lift the inner rod 65 upwards through the handle 61, causing the inner rod 65 to move the locking block 64 upwards in the through hole 57 and the limiting groove 58 of the sleeve rod 55. This causes the locking block 64 to disengage from the locking groove 35 and move upwards into the limiting groove 58 of the sleeve rod 55, thus releasing the sleeve rod 55 from its locked state. At the same time, the inner rod 65 separates from the mounting groove 34 of the limiting plate 32. Then, continue... Rotate the inner rod 65 through the handle 61, causing the inner rod 65 to rotate on the rotating shaft 33. The inner rod 65 drives the sleeve rod 55 to rotate on the limiting plate 32 of the support plate 31 through the locking block 64. The connecting rod 53 sliding in the guide groove 56 of the sleeve rod 55 drives the collar 52 and the ring plate 54 to rotate synchronously. The connecting scraper 51 between the ring plates 54 cleans the inner frame 21. Then, use the handheld nozzle to rinse the inside of the filter element through the water inlets of the upper end cover 1 and the lower end cover 3 to rinse out the residue. Then, while rotating the handle 61, push it downwards so that the locking block 64 on the inner rod 65 rotates to the locking groove 35 and slides downwards into the locking groove 35. Then, rotate the handle 61 in the opposite direction to remove the handle 61 from the inner rod 65. The rinsing of the filter element is then completed. After the water is removed, the filter element can be installed into the filter cartridge of the equipment for use.
