[0002] Existing multi-layer filtration and purification devices still suffer from low filtration efficiency and poor removal of fine particles and pollutants in practical use. Although some devices employ multi-layer filtration structures, the synergistic effect between the layers is not ideal, resulting in an overall purification effect that falls short of expectations. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a highly efficient multi-layer filtration and purification device that can overcome or at least partially solve the above problems.

[0004] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: a high-efficiency multi-layer filtration and purification device, including a shell, and further including: a fixed connecting box fixedly connected to the shell, a fixed barb inserted into the fixed connecting box, and a protective shell fixedly connected to the fixed barb; the protective shell is provided with four sets inside the shell, and the protective shell is fixedly connected from top to bottom to a pre-filter layer, a medium-efficiency filter layer, a high-efficiency filter layer and a fine filter layer. The pre-filter layer uses a large-pore metal wire mesh to intercept large particulate impurities, the medium-efficiency filter layer is made of fiber filter material, the high-efficiency filter layer is a nano-scale filter membrane, and the fine filter layer is an activated carbon adsorption layer; a guide plate is fixedly connected to the protective shell, and the guide plate is inclined to guide the fluid to be filtered to pass evenly through the pre-filter layer, the medium-efficiency filter layer, the high-efficiency filter layer and the fine filter layer.

[0005] Furthermore, a rotating shaft is rotatably connected to the outer shell, a cover plate is fixedly connected to the rotating shaft, and a buckle is fixedly connected to the outer shell, with the center of the buckle being hollow.

[0006] Furthermore, a fixing seat is fixedly connected to the cover plate, a tightening handle is rotatably connected to the fixing seat, and a hook is rotatably connected to the tightening handle. The end of the hook near the buckle is in the shape of a barb.

[0007] Furthermore, an observation window is fixedly connected to the cover plate. The observation window is made of transparent glass and is located at the corresponding position of each filter layer to observe the working status of each filter layer.

[0008] Furthermore, a sealing cover is fixedly connected to the outer casing. The sealing cover is funnel-shaped. A flow valve is fixedly connected to the sealing cover. A rotating block is rotatably connected to the flow valve. A handle is fixedly connected to the rotating block. A control vane is fixedly connected to the rotating block. The diameter of the control vane is the same as the inner diameter of the flow valve.

[0009] Furthermore, the flow valve is threaded with an input pipe.

[0010] Furthermore, the fixed connection box has a slot, which corresponds to the fixed barb.

[0011] Furthermore, the surface of the fiber filter material in the medium-efficiency filter layer is chemically treated to form a hydrophilic or hydrophobic surface coating.

[0014] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention, through a carefully designed multi-layer filtration structure, allows the large-pore metal wire mesh of the primary filter layer to quickly intercept large particulate impurities, preventing them from clogging subsequent filter layers and extending the overall service life of the device. The medium-efficiency filter layer uses fiber filter material with a specific fiber diameter, which can effectively capture particulate pollutants of medium size. The nano-scale filter membrane of the high-efficiency filter layer, with its extremely small pore size, can intercept even nano-sized tiny particles and pollutants, ensuring that the purification effect reaches an extremely high standard. The activated carbon adsorption layer of the fine filter layer, especially the modified activated carbon, can further remove residual organic pollutants, odors, etc. through physical adsorption and chemical action, significantly improving the quality of the purified fluid.

[0015] The inclined guide plates set between each filter layer can effectively guide the fluid to be filtered to pass evenly through each layer. This not only avoids the problem of uneven filtration caused by the fluid flow rate being too fast or too slow in a local area, but also allows each filter layer to give full play to its filtration capacity, improves the overall filtration efficiency, and reduces the purification dead zones caused by uneven fluid distribution.

[0016] The observation window on the outer casing allows operators to observe the working status of each filter layer in real time, promptly detect any problems such as clogging or damage, and perform maintenance and replacement accordingly.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0028] Example: Refer to Figures 1-7A high-efficiency multi-layer filtration and purification device includes a housing 1 and a fixed connection box 47 fixedly connected to the housing 1. A fixing hook 46 is inserted into the fixed connection box 47, and a protective shell 4 is fixedly connected to the fixing hook 46. The protective shell 4 has four sets inside the housing 1. From top to bottom, the protective shell 4 is fixedly connected to a pre-filter layer 41, a medium-efficiency filter layer 42, a high-efficiency filter layer 43, and a fine filter layer 44. The pre-filter layer 41 uses a large-pore metal wire mesh to intercept large particulate impurities. The medium-efficiency filter layer 42 is made of fiber filter material. The high-efficiency filter layer 43 is a nano-scale filter membrane, and the fine filter layer 44 is an activated carbon adsorption layer. A guide plate 45 is fixedly connected to the protective shell 4. The guide plate 45 is inclined to guide the fluid to be filtered to pass evenly through the pre-filter layer 41, the medium-efficiency filter layer 42, the high-efficiency filter layer 43, and the fine filter layer 44.

[0029] A rotating shaft 11 is rotatably connected to the outer shell 1, a cover plate 12 is fixedly connected to the rotating shaft 11, and a buckle 13 is fixedly connected to the outer shell 1, with the buckle 13 having a hollow center.

[0030] A fixed base 14 is fixedly connected to the cover plate 12, a tightening handle 15 is rotatably connected to the fixed base 14, and a hook 16 is rotatably connected to the tightening handle 15. The end of the hook 16 near the buckle 13 is in the shape of a barb.

[0031] An observation window 17 is fixedly connected to the cover plate 12. The observation window 17 is made of transparent glass and is located at the corresponding position of each filter layer. It is used to observe the working status of each filter layer.

[0032] A sealing cover 2 is fixedly connected to the outer casing 1. The sealing cover 2 is funnel-shaped. A flow valve 21 is fixedly connected to the sealing cover 2. A rotating block 22 is rotatably connected to the flow valve 21. A handle 23 is fixedly connected to the rotating block 22. A control vane 24 is fixedly connected to the rotating block 22. The diameter of the control vane 24 is the same as the inner diameter of the flow valve 21.

[0033] The flow valve 21 is threadedly connected to the input pipe 3;

[0034] The fixed connection box 47 is provided with a slot 48, which corresponds to the fixed barb 46;

[0035] The surface of the fiber filter material of the medium-efficiency filter layer 42 is chemically treated to form a surface coating with hydrophilic or hydrophobic properties.

[0036] The high-efficiency filter layer 43 has a nanoscale filter membrane with a composite structure;

[0037] The activated carbon in the fine filter layer 44 is modified activated carbon, which is prepared by loading metal oxides onto the surface of activated carbon.

[0038] Through a carefully designed multi-layer filtration structure, the large-pore metal wire mesh of the pre-filter layer 41 can quickly intercept large particulate impurities, preventing them from clogging subsequent filter layers and extending the overall service life of the device. The medium-efficiency filter layer 42 uses fiber filter material with a specific fiber diameter, which can effectively capture medium-sized particulate pollutants. The nano-scale filter membrane of the high-efficiency filter layer 43, with its extremely small pore size, can intercept even nano-sized particles and pollutants, ensuring that the purification effect reaches an extremely high standard. The activated carbon adsorption layer of the fine filter layer 44, especially the modified activated carbon, can further remove residual organic pollutants, odors, etc. through physical adsorption and chemical action, significantly improving the quality of the purified fluid.

[0039] The inclined guide plates 45 set between each filter layer can effectively guide the fluid to be filtered to pass through each layer evenly. This not only avoids the problem of uneven filtration caused by the fluid flow rate being too fast or too slow in a local area, but also allows each filter layer to give full play to its filtration capacity, improves the overall filtration efficiency, and reduces the purification dead zones caused by uneven fluid distribution.

[0040] The medium-efficiency filter layer 42 has a hydrophilic or hydrophobic coating formed on the surface of the fiber filter material through chemical treatment. Depending on the characteristics of the filtered object, it can enhance the capture ability of different types of pollutants. The hydrophilic coating helps to adsorb pollutants containing moisture, while the hydrophobic coating has a better interception effect on oily pollutants. The high-efficiency filter layer 43 has a composite structure of nano-scale filter membrane and specific active ingredients in the functional layer, which can chemically react with specific pollutants, decompose or transform them into harmless substances, and further improve the purification effect. The modified activated carbon in the fine filter layer 44, through loading metal oxides, significantly enhances the adsorption and catalytic decomposition ability of certain specific pollutants.

[0041] The observation window 17 on the outer casing 1 allows operators to observe the working status of each filter layer in real time, promptly detect any blockages or damage, and perform maintenance and replacement. Each filter layer adopts a detachable structure. By pushing the tightening handle 15 in the opposite direction to the outer casing 1, the tightening handle 15 rotates on the fixed base 14, causing the hook 16 to disengage from the buckle 13. Then, the cover plate 12 on the outer casing 1 is opened, and the protective shell 4 is lifted. The fixing hook 46 on the protective shell 4 disengages from the slot 48 on the fixed connection box 47, allowing the protective shell 4 to be removed or installed. This makes the operation of replacing the filter layer simple and convenient, reducing maintenance costs and time. When the handle 23 on the flow valve 21 is rotated, it drives the rotation angle of the control blade 24 to control the inflow speed, improve energy utilization efficiency, and reduce the amount of manual intervention.

[0042] This invention employs a meticulously designed multi-layer filtration structure. The large-pore metal wire mesh of the primary filter layer 41 can quickly intercept large particulate impurities, preventing them from clogging subsequent filter layers and extending the overall service life of the device. The medium-efficiency filter layer 42 uses fiber filter material with a specific fiber diameter, which can effectively capture medium-sized particulate pollutants. The nano-scale filter membrane of the high-efficiency filter layer 43, with its extremely small pore size, can intercept even nano-sized particles and pollutants, ensuring that the purification effect reaches an extremely high standard. The activated carbon adsorption layer of the fine filter layer 44, especially the modified activated carbon, can further remove residual organic pollutants, odors, etc. through physical adsorption and chemical action, significantly improving the quality of the purified fluid.

[0043] The inclined guide plates 45 set between each filter layer can effectively guide the fluid to be filtered to pass through each layer evenly. This not only avoids the problem of uneven filtration caused by the fluid flow rate being too fast or too slow in a local area, but also allows each filter layer to give full play to its filtration capacity, improves the overall filtration efficiency, and reduces the purification dead zones caused by uneven fluid distribution.

[0044] The observation window 17 on the outer casing 1 allows operators to observe the working status of each filter layer in real time, and promptly detect whether there are problems such as blockage or damage to the filter layer, so as to carry out maintenance and replacement.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model.
