[0032] To make the objectives, technical solutions, and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. 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 fall within the scope protected by the present utility model.

[0033] See Figures 1-6 As shown, the present utility model provides a sheet-shaped flexible activated carbon filtration and adsorption device, which includes a filtration housing 1. A filtration chamber for accommodating a filtration sleeve 4 and a fluid to be filtered is formed inside the filtration housing 1. Both sides of the filtration chamber are open, and filtration end caps 2 are detachably arranged at the openings respectively. The opening shape and size of the filtration chamber are adapted to the filtration end caps 2 to ensure that the filtration end caps 2 can be tightly installed. An opening and closing drive assembly 3 is arranged between the two filtration end caps 2;

[0034] A number of filtration sleeves 4 are detachably arranged in the filtration chamber, and the filtration sleeves 4 can be tightly arranged in the filtration chamber. The material of the filtration sleeve 4 can be materials such as plastics and metals with certain strength and corrosion resistance. A sheet-shaped filtration structure 5 is arranged in each filtration sleeve 4. The sheet-shaped filtration structure 5 includes a mesh layer 502, and a sheet-shaped activated carbon layer 501 is covered on the mesh layer 502. The material of the mesh layer 502 can be nylon, polyester, etc., which has certain strength and filtration performance, and is used to support the sheet-shaped activated carbon layer 501 and preliminarily filter larger-particle impurities. The sheet-shaped activated carbon layer 501 is formed by pressing activated carbon particles and is closely attached to the mesh layer 502, and is used to adsorb substances such as impurities and odors in the fluid.

[0035] Outlet pipes 101 for discharging the filtered fluid from the filtration chamber and inlet pipes 102 for introducing the fluid to be filtered into the filtration chamber are respectively arranged at the openings on both sides of the filtration housing 1. Flange plates are respectively arranged at the ends of the outlet pipes 101 and the inlet pipes 102.

[0036] See the attached Figure 1 and Figure 4 As shown, the opening and closing drive assembly 3 includes cross beams 303 respectively fixedly arranged on the two filtration end caps 2. Electric telescopic rods 301 are respectively arranged between the two ends of the two cross beams 303. A support seat 302 is fixedly arranged on each electric telescopic rod 301, and the support seat 302 is rotatably connected to the outer side wall of the filtration housing 1 through a rotating shaft 306. A limiting protrusion 304 for limiting the support seat 302 is convexly arranged on the outer side wall of the filtration housing 1. Adjusting through holes for cooperating with the push rod head ends of the electric telescopic rods 301 are opened at both ends of the cross beam 303, and a fixing bolt 305 for tightly abutting against the push rod head ends of the electric telescopic rods 301 is threadedly connected to the end of the cross beam 303.

[0037] At the edges of the openings on both sides of the filter housing 1, there are sealing washers 103 for abutting and sealing with the filter end cap 2. An inner nest 201 for fitting and engaging with the opening of the filter housing 1 is provided on the filter end cap 2. Two or more inner push rods 202 for abutting and limiting the filter sleeve 4 are connected to the inner nest 201. When the filter end cap 2 is installed, the end of the inner push rod 202 can abut on the filter sleeve 4 to realize the limiting effect on the filter sleeve 4 and prevent each filter sleeve 4 from shifting during the fluid flow process.

[0038] Working principle:

[0039] During use, the fluid to be filtered enters the filter chamber of the filter housing 1 from the inlet pipe 102. The flange at the end of the inlet pipe 102 facilitates the connection with the external pipeline. After the fluid enters the filter chamber, it flows through a number of filter sleeves 4 in sequence. The sheet-shaped filter structure 5 in the filter sleeve 4 is composed of a mesh cloth layer 502 and a sheet-shaped activated carbon layer 501 covering it. The sheet-shaped activated carbon layer 501 utilizes the adsorption characteristics of activated carbon to adsorb impurities, odors and other substances in the fluid, and the mesh cloth layer 502 plays a role in supporting and preliminarily filtering larger particles, realizing the purification and filtration of the fluid.

[0040] The opening and closing drive assembly 3 is used to control the opening and closing of the filter end cap 2. The two ends of the electric telescopic rod 301 are respectively connected to the cross beam rod 303, and the cross beam rod 303 is fixed on the filter end cap 2. The electric telescopic rod 301 is rotationally connected to the outer side wall of the filter housing 1 through the support seat 302 and the rotating shaft 306. During operation, the electric telescopic rod 301 expands and contracts to drive the cross beam rod 303 and the filter end cap 2 to move, realizing the opening and closing of the filter end cap 2. The limiting protrusion 304 can limit the support seat 302 to ensure the accuracy of the position of the electric telescopic rod 301 when the filter end cap 2 is closed. After the filter end cap 2 is opened, the filter sleeve 4 closest to the inlet pipe 102 is removed, and a new filter sleeve 4 is placed into the opening from the side closest to the outlet pipe 101.

[0041] The sealing washer 103 at the edge of the opening of the filter housing 1 cooperates with the inner nest 201 on the filter end cap 2 to achieve good sealing and prevent fluid leakage. The inner push rod 202 on the inner nest 201 can abut and limit the filter sleeve 4 to ensure the stable position of the filter sleeve 4 in the filter chamber.

[0042] The filtered fluid flows out from the outlet pipe 101, and the flange at the end of the outlet pipe 101 facilitates the connection with the subsequent pipeline.

[0043] The above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims described above.
