[0002] Activated carbon filtration is a water treatment process that utilizes the adsorption properties of activated carbon. Activated carbon has a highly porous structure and well-developed pores, enabling it to adsorb impurities, odors, pigments, heavy metal ions, and other pollutants from water, thereby improving water quality. Activated carbon filter boxes are used to purify harmful gases and odors in the air, achieving purification through adsorption.
[0003] In the prior art, such as in publication number CN205023904U, an activated carbon fiber composite filter element is disclosed, which includes a hollow cylindrical filter element body, the filter element body including a hollow cylindrical filter element skeleton and an activated carbon fiber composite material wound around the filter element skeleton; a filter element protective mesh covering the outer side of the filter element body; an upper end cap respectively disposed at both ends of the filter element body and connected to the upper end of the filter element body and a lower end cap connected to the lower end of the filter element body;
[0004] Although the aforementioned patent improves the filtration and adsorption performance of the activated carbon fiber composite filter cartridge by winding activated carbon fiber composite material onto the filter cartridge skeleton, creating sufficient micro-gaps between the thin activated carbon fiber composite material layers and between the winding layers, allowing for more thorough contact between the liquid to be treated and the adsorbent material, the filter cartridge requires replacement, maintenance, and cleaning after a period of filtration. However, the inconvenience of disassembly and assembly leads to maintenance difficulties. Furthermore, the activated carbon filter plate cannot perform layered filtration, resulting in poor filtration performance. Therefore, a high-performance activated carbon fiber composite material filtration device is proposed to address these issues. Utility Model Content

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A high-performance activated carbon fiber composite material filter device of this utility model includes a filter cylinder; the top and bottom of one end of the filter cylinder are symmetrically provided with limiting holes, and a circular block is inserted inside; the top and bottom of the circular block are symmetrically provided with fixing holes and a spring and a limiting post are provided inside; an elastic sealing ring is sleeved on the surface of the circular block and an air inlet is provided on the side; a cylindrical filter screen is connected to one side of the circular block; a cylindrical frame is provided inside the filter cylinder; a cylindrical shell is provided inside the cylindrical frame; the cylindrical filter screen is sleeved inside the cylindrical shell; a rectangular groove is provided on the side of the cylindrical shell; a plurality of activated carbon filter plates are arranged circumferentially inside the cylindrical frame and their filtration performance increases sequentially from the side closest to the rectangular groove; one end of the filter cylinder is connected to an air outlet pipe and the other end is connected to an air inlet pipe; the limiting post is engaged in the limiting hole.
[0007] Preferably, the end of the limiting post has a hemispherical structure, the compression stroke of the spring is greater than the depth of the limiting hole, and the elastic sealing ring is made of fluororubber and is interference-fitted with the inner wall of the filter cylinder.
[0008] Preferably, the rectangular grooves of the cylindrical shell are equidistantly distributed along the axial direction, and their opening direction is perpendicular to the arrangement direction of the activated carbon filter plate.

[0012] The advantages of this utility model are:
[0013] 1. This utility model uses a spring-limiting post structure design with a circular block and a limiting hole. When the spring is compressed, the limiting post retracts into the fixing hole, releasing the jamming with the limiting hole. The elastic sealing ring ensures the airtightness during the insertion and removal process, realizing the quick disassembly and assembly of the filter element assembly. This solves the problem of difficult maintenance of traditional filter devices. Pressing the limiting post can unlock the circular block and remove the entire filter screen and activated carbon filter plate, improving maintenance efficiency.
[0014] 2. This utility model utilizes a gradient arrangement design of activated carbon filter plates to achieve gas uniform flow from the rectangular groove of the cylindrical casing. The porosity of the activated carbon filter plates decreases along the flow direction, intercepting pollutants of different particle sizes step by step, thus realizing a multi-stage progressive purification function for the gas. This solves the problem of low efficiency in traditional single-layer filtration. After the gas diffuses through the rectangular groove, it passes through the activated carbon filter plates with decreasing porosity in sequence, thereby increasing the adsorption capacity.

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 scope of protection of the present utility model.
[0022] Please see Figures 1-4As shown, a high-performance activated carbon fiber composite material filtration device includes a filter cylinder 1; symmetrical limiting holes 2 are opened at the top and bottom of one end of the filter cylinder 1, and a circular block 3 is inserted inside it; symmetrical fixing holes 4 are opened at the top and bottom of the circular block 3, and a spring 5 and a limiting post 6 are set inside it; an elastic sealing ring 7 is sleeved on the surface of the circular block 3, and an air inlet hole 8 is opened on the side; a cylindrical filter screen 9 is connected to one side of the circular block 3; a cylindrical frame 10 is set inside the filter cylinder 1; a cylindrical shell 11 is set inside the cylindrical frame 10, and the cylindrical filter screen 9 is sleeved inside the cylindrical shell 11; a rectangular groove 15 is opened on the side of the cylindrical shell 11; a number of activated carbon filter plates 12 are arranged circumferentially inside the cylindrical frame 10, and their filtration performance increases sequentially from the side closest to the rectangular groove 15; an air outlet pipe 13 passes through one end of the filter cylinder 1 and an air inlet pipe 14 passes through the other end; and the limiting post 6 is engaged in the limiting hole 2.
[0023] During operation, gas enters the filter cartridge 1 through the inlet pipe 14, flows into the cylindrical filter screen 9 through the inlet hole 8 of the circular block 3 to intercept large particulate impurities, and then diffuses through the rectangular groove 15 of the cylindrical shell 11 to the activated carbon filter plate 12 area. After being filtered step by step, it is discharged through the outlet pipe 13. During maintenance, pressing the limit post 6 compresses the spring 5 to disengage from the limit hole 2, and the circular block 3 is pulled out along with the cylindrical filter screen 9 and the cylindrical frame 10 for overall cleaning. The modular structure enables quick disassembly and assembly of the filter element, shortening maintenance time. The gradient filtration of the activated carbon filter plate 12 improves purification efficiency.
[0024] Furthermore, the end of the limiting post 6 is a hemispherical structure, the compression stroke of the spring 5 is greater than the depth of the limiting hole 2, and the elastic sealing ring 7 is made of fluororubber and is interference-fitted with the inner wall of the filter cylinder 1.
[0025] During operation, the hemispherical structure at the end of the limiting post 6 reduces frictional resistance when pressed, the compression stroke of the spring 5 covers the depth of the limiting hole 2 to ensure stable unlocking, and the elastic sealing ring 7 made of fluororubber provides interference seal to prevent gas leakage. The hemispherical limiting post 6 and the spring 5 work together to ensure smooth disassembly and assembly.
[0026] Furthermore, the rectangular grooves 15 of the cylindrical shell 11 are equidistantly distributed along the axial direction, and their opening direction is perpendicular to the arrangement direction of the activated carbon filter plate 12. The cylindrical filter screen 9 is a sintered stainless steel filter element.
[0027] During operation, the rectangular grooves 15 of the cylindrical housing 11 are evenly distributed along the axial direction, allowing the gas to enter the activated carbon filter plate 12 area uniformly. The cylindrical filter screen 9 of the stainless steel sintered filter element intercepts impurities with a particle size >50μm. The rectangular grooves 15 optimize the uniformity of gas distribution and improve the impact resistance of the stainless steel filter element.
[0028] Furthermore, the porosity of the activated carbon filter plate 12 decreases along the gas flow direction, and its surface is coated with a nano-titanium oxide coating. The columnar frame 10 is detachably connected to the inner wall of the filter cylinder 1 through a snap-fit structure.

[0030] Furthermore, a conical baffle is provided at the inlet end of the air intake pipe 14, and its outlet end is coaxially aligned with the cylindrical filter screen 9. The inner wall of the air outlet pipe 13 is provided with a sound-absorbing corrugated structure.
[0031] During operation, the conical air intake shroud of the intake pipe 14 guides the airflow smoothly into the center of the cylindrical filter screen 9, and the sound-absorbing corrugated structure of the exhaust pipe 13 cancels out airflow noise through sound wave reflection.
[0032] Furthermore, flow guide baffles are provided between the activated carbon filter plates 12 of the column frame 10, and the inclination angle of the flow guide baffles forms an angle with the opening direction of the rectangular groove 15.
[0033] During operation, the flow guide baffle guides the gas to flow horizontally along the surface of the activated carbon filter plate 12 at an inclined angle, and the included angle direction matches the opening of the rectangular groove 15, thus prolonging the gas contact time.
[0034] Working principle: After the gas enters the filter cartridge 1 through the air inlet pipe 14, it flows into the cylindrical filter screen 9 through the air inlet hole 8 of the circular block 3 to intercept large particulate impurities. Then, it diffuses through the rectangular groove 15 of the cylindrical shell 11 to the area of the circumferentially set activated carbon filter plate 12. It is purified step by step according to the gradient of increasing filtration performance, and finally discharged from the air outlet pipe 13. During maintenance, press the limit post 6 to compress the spring 5 to disengage from the limit hole 2, and pull out the circular block 3 along with the cylindrical filter screen 9 and the cylindrical frame 10 for cleaning. The elastic sealing ring 7 ensures the airtightness during the insertion and removal process. The angle design between the flow guide baffle and the rectangular groove 15 optimizes the airflow distribution.
