Abstract
Description
Technical Field
[0001] This utility model belongs to the field of active filter media sorting technology, specifically an active filter media sorting and recycling device. Background Technology
[0002] High-density activated filter media is an amorphous aluminosilicate (glass) industrial product specially designed and manufactured in a state-of-the-art filter media processing plant using recycled green and amber glass bottles. After migrating, suspended particles, upon approaching the filter media surface, are attracted by electrostatic forces, chemical adsorption forces, and van der Waals forces, causing them to adhere to the surface. Since colored glass contains metal oxides, special catalysts are added during the activation process. These catalysts react with the metal oxides, creating a high redox potential on the filter media surface. This treatment prevents the filter media from caking.
[0003] Based on this, existing technologies can place activated filter media in layers of particles of different sizes to achieve the filtration effect of removing oil and preventing sticking in water. However, over a long period of time, the different particles begin to mix at the layering points, making it difficult to reuse them. Utility Model Content

[0025] Secondly, this utility model is described in detail with reference to the schematic diagrams.

[0026] Example 1
[0027] Reference Figures 1-3 This embodiment provides an active filter media sorting and reuse device, including a housing 100, a sorting chamber 101 disposed in the housing 100, a rotating shaft 200 disposed in the sorting chamber 101, a multi-layer partition 102 disposed in the sorting chamber 101, a multi-stage sieve plate 201 disposed on the rotating shaft 200, and the multi-stage sieve plate 201 being correspondingly disposed on the multi-layer partition 102.
[0028] The sieve plate 201 includes a large-hole sieve plate 201a, a small-hole sieve plate 201b, and a dense mesh plate 201c. The large-hole sieve plate 201a, the small-hole sieve plate 201b, and the dense mesh plate 201c are all concave plate structures with a concave center and an upward-facing edge.
[0029] The large-pore screen 201a, small-pore screen 201b, and dense mesh screen 201c cause the material falling on them to begin to move under a certain centrifugal force, and to begin to stratify according to different sizes. Larger and heavier active filter media particles are further outward. The concave disc structure further amplifies the differences between particles of different sizes. Specifically, smaller particles are less likely to move outward under centrifugal motion, and are less likely to move upward along the concave disc structure, thus causing larger and heavier materials to be further outward.
[0030] The diameters of the large-hole sieve disc 201a, the small-hole sieve disc 201b, and the dense mesh disc 201c decrease sequentially.
[0031] The aperture size of the large-hole sieve 201a, the small-hole sieve 201b, and the dense mesh sieve 201c decreases and the number of holes increases in that order.
[0032] The large-pore sieve disc 201a, the small-pore sieve disc 201b, and the dense mesh disc 201c are used to sort particles of different sizes. It should be noted that in this embodiment, the particles are used to distinguish between three size ranges: large, medium, and small. The specific size is limited according to the actual situation. The pore size of the large-pore sieve disc 201a allows medium and small-sized filter media to pass through, leaving large-sized materials. The small-pore sieve disc 201b allows small-sized filter media to pass through, while medium-sized filter media are screened out here. The dense mesh disc 201c cannot allow any size filter media to pass through; its purpose is for ventilation and isolation.
[0033] The partition 102 includes a first conical plate 102a, a second conical plate 102b, and a third conical plate 102c, all of which are connected to the side wall of the housing 100.
[0034] The first cone plate 102a, the second cone plate 102b, and the third cone plate 102c are used to isolate the filter media after sorting.
[0035] The first cone plate 102a has a first opening 102d, which is located below the edge of the large-hole sieve plate 201a; the second cone plate 102b has a second opening 102e, which is located below the edge of the small-hole sieve plate 201b; and the third cone plate 102c has a third opening 102f, which is located below the edge of the dense mesh plate 201c.
[0036] The housing 100 has a first outlet 103, a second outlet 104 and a third outlet 105 on its side wall. The first outlet 103, the second outlet 104 and the third outlet 105 are respectively disposed on the first cone plate 102a, the second cone plate 102b and the third cone plate 102c.
[0037] Specifically, depending on the selected rotation speed, large-sized filter media can fly out from the edge of the large-hole screen 201a onto the first cone plate 102a and be discharged through the first outlet 103. Medium-sized filter media are discharged from the small-hole screen 201b through the second cone plate 102b and from the second outlet 104. Small-sized filter media are guided from the dense screen 201c through the third cone plate 102c and discharged from the third outlet 105.
[0038] For the filter media on the large-pore screen 201a, due to the limited rotation speed and centrifugal force, only the large-sized filter media can fly out of the large-pore screen 201a, while the medium and small-sized media remain on the large-pore screen 201a and fall to the small-pore screen 201b for further sorting during the movement.
[0039] It should be noted that the size, pore size, and rotation speed of the large-pore screen disc 201a need to be determined according to the size distribution range of the active filter media.
[0040] Furthermore, since the filter media size range is not strictly stratified, during operation, only large-sized filter media will fly out from the large-pore screen 201a. At the same time, some large-sized filter media will inevitably remain on the large-pore screen 201a. Medium and small-sized filter media will not fly out, but will fall into the lower layer for further sorting. The same applies to the small-pore screen 201b.
[0041] In addition, since the large-pore screen 201a, small-pore screen 201b and dense mesh screen 201c are of different sizes, medium-sized filter media can be centrifuged out from the small-pore screen 201b, while small-sized filter media can be centrifuged out from the dense mesh screen 201c.
[0042] It should be noted that each outlet is equipped with cones to guide the outward flow of materials and recycling bins for storing materials, which will not be described in detail here.
[0043] A motor 202 is connected to the top of the rotating shaft 200.
[0044] The top of the housing 100 is provided with a top cover 203, and the top cover 203 is provided with a feeding port 204.
[0045] To improve efficiency, activated filter media of different particle sizes are mixed together and washed with acid. After washing and drying, the activated filter media to be sorted is added into the device through the feed port 204 for sorting.
[0046] Furthermore, a heating element can be provided on the inner side of the third cone plate 102c, and a fan blade can be provided on the upper side of the rotating shaft 200. During the rotation, the hot air is carried upward to further remove residual moisture.
[0047] It should be noted that the motor can operate in an intermittent rotation mode, such as first rotating slowly in both forward and reverse directions for 10 seconds to screen the material, then rotating rapidly for 3 seconds to make the corresponding filter material fly out, and then stopping for 3 seconds. This working mode is also in line with the mode that the motor should not work continuously for a long time, which ensures both the motor life and the sorting efficiency.
[0048] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.
[0049] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
