[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] During actual use, after long-term use, a large amount of impurities will accumulate inside the filter screen, requiring staff to frequently clean the filter screen, resulting in a shorter lifespan of the filter screen and affecting the filtering effect.

[0019] In view of this, the present utility model provides a new type of sintered structure activated carbon filter element, which solves the problem that during actual use, after long-term use, a large amount of impurities will accumulate inside the filter screen, requiring staff to frequently clean the filter screen, resulting in a shorter lifespan of the filter screen and affecting the filtering effect.

[0020] By those skilled in the art, the components in this case are connected in sequence. For the specific connection and operation sequence, reference should be made to the following working principle. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process.

[0021] Embodiment 1: As Figures 1-4 can be seen, a new type of sintered structure activated carbon filter element includes a filter screen 1. A cover plate 11 is sleeved on the top of the filter screen 1. The outer wall of the filter screen 1 is threadedly connected with a fixing plate 12 below. A connecting pipe 15 is communicated with the bottom of the fixing plate 12. The new type of sintered structure activated carbon filter element includes a cleaning structure 2 and a fixing structure 3. The cleaning structure 2 is installed on the inner wall of the filter screen 1; the fixing structure 3 is installed between the fixing plate 12 and the cover plate 11; wherein, the inside of the filter screen 1 is cleaned through the cleaning structure 2, and the fixing structure 3 connects the fixing plate 12 and the cover plate 11 together;

[0022] In the specific implementation process, it is particularly worth noting that the filter screen 1 is fixed by using the fixing plate 12 and the cover plate 11. With the cooperation of the cleaning structure 2, the inside of the filter screen 1 is cleaned during the working process of the filter screen 1. Under the action of the fixing structure 3, the cover plate 11 and the fixing plate 12 are connected together to fix the filter screen 1. It is also worth noting that the filter screen 1 is made by mixing activated carbon powder and high-molecular heat-melt pore-forming materials and pouring them into a specific mold for sintering. Other material powders can be added to make a composite filter element. Through the unique manufacturing process and deep filtration effect, the filter element forms ultra-fine filter pores with tortuous pore diameters, greatly prolonging the contact time between the fluid and the activated carbon during use, and having a better filtration effect. Moreover, the pore diameter of the filter screen 1 can be adjusted arbitrarily as needed, up to 0.2 microns. The activated carbon has a porous structure, a large specific surface area with tortuous pore diameters, can fully exert the performance of the activated carbon, and has strong integrity after sintering and can withstand a pressure of 1 MPa;

[0023] Furthermore, the cleaning structure 2 includes a fixing frame 21, a connecting rod 22, a turbine 23, a cleaning brush 24 and a top block 25. The fixing frame 21 is fixedly connected to the top of the fixing plate 12; the connecting rod 22 is rotatably connected to the top of the fixing frame 21 through a sealing bearing; the turbine 23 is fixedly connected to the outer wall of the connecting rod 22; the cleaning brush 24 is fixedly connected to the outer wall of the connecting rod 22, and the side away from the connecting rod 22 is attached to the inner wall of the filter screen 1. The surface of the cleaning brush 24 is soft, and pressing tightly will not affect the rotation of the connecting rod 22; the top block 25 is rotatably connected to one end of the connecting rod 22 away from the fixing frame 21 through a sealing bearing, and the end away from the connecting rod 22 presses tightly against the bottom of the cover plate 11; wherein, through the cooperation of the fixing frame 21 and the connecting rod 22, the turbine 23 and the cleaning brush 24 clean the filter screen 1, and the top block 25 ensures the stability of the connecting rod 22 during rotation;

[0024] In the specific implementation process, it is particularly worth noting that the cleaning brush 24 presses tightly against the inner wall of the filter screen 1 under the action of the connecting rod 22. In this way, when the cleaning brush 24 rotates, the inside of the filter screen 1 can be cleaned. The turbine 23 will rotate under the drive of liquid or gas, and under the drive of the connecting rod 22, the cleaning brush 24 cleans the inner wall of the filter screen 1 to prevent blockage during filtration;

[0025] Furthermore, an inner support ring 13 is inserted into the inner wall of the filter screen 1, and the top of the inner support ring 13 is fixedly connected to the bottom of the cover plate 11;

[0026] In the specific implementation process, it is particularly worth noting that when installing the filter screen 1, the filter screen 1 is inserted between the inner support ring 13 and the cover plate 11, so that the installation of the filter screen 1 is stable. Moreover, the material of the inner support ring 13 is rubber material, which can also play a sealing role;

[0027] Specifically, when using this new sintered structure activated carbon filter element, when installing the filter screen 1, insert the filter screen 1 between the inner support ring 13 and the cover plate 11, and press it tightly against the upper fixing plate 12 at its bottom, clamping the filter screen 1 between the cover plate 11 and the fixing plate 12. When installing the fixing plate 12, insert the cleaning brush 24 into the interior of the filter screen 1, and install the filter element using the connecting pipe 15. When gas or liquid enters the interior of the filter screen 1, it will cause the turbine 23 to rotate. Since the turbine 23 is fixed to the outer wall of the connecting rod 22, the cleaning brush 24 will rotate with the turbine 23 to clean the inner wall of the filter screen 1, avoiding blockage.

[0028] Embodiment 2: As Figures 1-4 It can be seen that the fixing structure 3 includes a plug rod 31 and a fixing bolt 32. The plug rod 31 is fixedly connected to the top of the fixing plate 12, and its top is inserted into the cover plate 11 and extends above the cover plate 11; the fixing bolt 32 is threadedly connected to the side wall of the cover plate 11, and the end extending into the interior of the cover plate 11 abuts against the outer wall of the plug rod 31. Among them, through the cooperation of the fixing bolt 32 and the plug rod 31, the cover plate 11 and the fixing plate 12 are fixed together;

[0029] In the specific implementation process, it is particularly worth noting that an opening groove is provided on the outer wall of the plug rod 31. After the plug rod 31 is inserted into the cover plate 11, use a wrench to tighten the fixing bolt 32, so that the fixing bolt 32 abuts against the opening groove on the outer wall of the plug rod 31. In this way, when replacing the filter screen 1 or performing maintenance, loosen the fixing bolt 32 and lift the cover plate 11, then the filter screen 1 can be removed for cleaning and replacement, avoiding separating the plug rod 31 and the cover plate 11, which is inconvenient for subsequent installation of the filter screen 1;

[0030] Furthermore, a sealing gasket 16 is pressed tightly between the filter screen 1 and the fixing plate 12, and a protective coating 14 is provided on the outer wall of the filter screen 1;

[0031] In the specific implementation process, it is particularly worth noting that when installing the filter screen 1, the filter screen 1 and the fixing plate 12 will squeeze the sealing gasket 16, thereby blocking the gap between the filter screen 1 and the fixing plate 12 to avoid leakage. The protective coating 14 can be selected from polymer materials, and the polymer materials can be selected from materials with good strength and wear resistance such as polyethylene and polypropylene. The coating method can adopt methods such as spraying and dipping;

[0032] Specifically, on the basis of the above embodiments, after the filter screen 1 is manufactured, a protective coating 14 is sprayed on its outer wall, which can increase the service life of the filter screen 1. And a gasket 16 is placed between the filter screen 1 and the fixing plate 12 to seal the gap between the two to prevent leakage. Moreover, when cleaning and overhauling the filter screen 1, loosen the fixing bolts 32 on the outer wall of the cover plate 11, lift the cover plate 11, and the filter screen 1 can be disassembled from both sides. When installing the filter screen 1, insert the filter screen 1 between the cover plate 11 and the fixing plate 12, then put down the cover plate 11, and tighten the fixing bolts 32 to fix the insertion rod 31 inside the cover plate 11, thereby fixing the filter screen 1.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
