Description

Technical Field

[0001] This utility model relates to the field of solid waste recycling technology for waste lithium batteries, and in particular to a filtration device for solid waste recycling. Background Technology

[0002] Solid waste from waste lithium batteries mainly refers to waste lithium iron phosphate batteries, ternary lithium batteries, lithium cobalt oxide batteries, nickel-hydrogen batteries, fuel cells, and other waste batteries generated in industrial production activities, as well as waste electrode sheets, waste cells, waste powder and slurry, and scraps generated during battery production. When recycling solid waste from waste lithium batteries, filtration is required to effectively remove internal metals, which facilitates the subsequent production and processing of environmentally friendly bricks.

[0003] The existing Chinese patent CN211802990U, disclosed on October 30, 2020, is a sorting device for solid waste, which relates to the field of solid waste technology. It includes: a sorting cylinder, a feeding port and support columns. The feeding port is embedded at the bottom of the sorting cylinder, and four support columns are welded to the outside of the feeding port. A discharge pipe is embedded at the lower right side of the sorting cylinder, and a crushing device is fixedly installed at the top center of the sorting cylinder.

[0004] However, in actual sorting and filtration, the crushing device crushes solid materials by extrusion, and the sorting cylinder screens them through mesh. Neither of these devices has a good metal screening capability and cannot effectively filter and screen metals in solid waste from waste lithium batteries, thus failing to effectively recycle metal waste.

[0005] Therefore, we propose a novel filtration device for solid waste recycling to solve the above-mentioned technical problems. Utility Model Content

[0034] Example 1

[0035] This embodiment provides a technical solution: a filtration device for solid waste recycling, such as... Figures 1-5 As shown, it includes a solid waste recycling filter body, a solid waste crushing mechanism, a filter sorting and receiving mechanism, a magnetic filtration mechanism, and an air separation filtration mechanism.

[0036] Two solid waste crushing mechanisms are symmetrically installed on the solid waste recycling filter body. The solid waste input into the solid waste recycling filter body can be effectively crushed by the two crushing mechanisms, forming fine particles that fall. The filtering and sorting receiving mechanism is fixed in the middle of the solid waste recycling filter body. The filtering and sorting receiving mechanism can receive the crushed material in the middle of the solid waste recycling filter body. The filtering and sorting receiving mechanism is located below the solid waste crushing mechanism, so that it can receive the material accordingly. The magnetic suction filtering mechanism is fixed in the inner left side of the solid waste recycling filter body. When the magnetic suction filtering mechanism is energized, it will be magnetized and will magnetically attract the metal material falling from the filtering and sorting receiving mechanism, thus achieving the purpose of magnetic filtration. The air classifying filtering mechanism is fixed in the inner right side of the solid waste recycling filter body. It can be stably installed and placed. The air classifying filtering mechanism can blow air force to filter the particles falling from the filtering and sorting receiving mechanism, effectively performing air classification filtration by utilizing the difference in mass.

[0037] like Figure 1 , Figure 2 and Figure 5As shown, the solid waste recycling filter body includes a solid waste recycling housing 1. A four-hole mounting base plate 11 is fixedly connected to the lower end of the solid waste recycling housing 1. The solid waste recycling housing 1 can be installed in designated positions via screws through the four-hole mounting base plate 11. A first belt conveyor 2 is fixedly connected to a slot on the lower right side of the solid waste recycling housing 1. Unscreened particulate materials inside the solid waste recycling housing 1 can be conveyed via the first belt conveyor 2. A maintenance cover 12 is installed in a groove at the upper end of the solid waste recycling housing 1 via screws for easy installation and removal. Opening the maintenance cover 12 allows for easy inspection of the interior of the solid waste recycling housing 1. The upper end is fixed with a lifting handle 13 for easy opening and closing by personnel. A concave shell 7 is fixed through the upper right side of the solid waste recycling box 1. The concave shell 7 has a concave space inside, which can effectively limit the installation. A second belt conveyor 71 is fixed inside the concave shell 7. The second belt conveyor 71 can stably transport the solid waste of environmentally friendly bricks that need to be filtered in the concave shell 7. A solid waste crushing mechanism is installed on the upper inner side of the solid waste recycling box 1, which can be stably placed for crushing. The discharge end of the second belt conveyor 71 is located above the two solid waste crushing mechanisms. When the falling material passes between the two solid waste crushing mechanisms, it can be effectively crushed in an alternating manner.

[0038] The solid waste crushing mechanism includes a crushing roller 61, which is rotatably mounted on the solid waste recycling box 1. It can be positioned and rotated for crushing. A first coupling 62 is fixedly connected to the front end of the crushing roller 61. When the first coupling 62 rotates, it can drive the crushing roller 61 to rotate. A crushing motor 6 is fixedly connected to the front end of the first coupling 62. When the output shaft of the crushing motor 6 rotates, it can drive the first coupling 62 to rotate. The crushing motor 6 is detachably mounted on the solid waste recycling box 1 by screws on the motor mounting plate 63, which facilitates the installation and removal of the crushing motor 6. The crushing motor 6 can be stably placed and driven on the solid waste recycling box 1. A filter sorting and receiving mechanism is fixedly connected to the bottom of the crushing roller 61 on the solid waste recycling box 1. The solid material crushed by the crushing roller 61 can fall into the filter sorting and receiving mechanism inside the solid waste recycling box 1.

[0039] During operation, the solid waste input into the solid waste recycling filter body is effectively crushed by two solid waste crushing mechanisms, forming fine particles that fall into the air. The filtration and sorting receiving mechanism receives the crushed material in the middle of the solid waste recycling filter body. The filtration and sorting receiving mechanism is located below the solid waste crushing mechanism, allowing for corresponding material reception. When energized, the magnetic filtration mechanism becomes magnetized and magnetically attracts the metal material falling from the filtration and sorting receiving mechanism, achieving the purpose of magnetic filtration. The air-separation filtration mechanism is fixed to the inner right side of the solid waste recycling filter body for stable installation. The air-separation filtration mechanism uses airflow to filter the particles falling from the filtration and sorting receiving mechanism, effectively performing air separation filtration based on differences in mass.

[0040] Example 2

[0041] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figures 1-4 As shown, to further better realize this utility model, the following arrangement is specifically adopted: the filtering and sorting receiving mechanism includes a receiving hopper 31, and a conical collecting cavity 34 is opened on the inner side of the upper end of the receiving hopper 31. The receiving hopper 31 can collect and receive the material crushed by the crushing roller 61 through the area of ​​the conical collecting cavity 34. A discharge vertical pipe 33 is fixedly connected to the lower end of the receiving hopper 31. The receiving hopper 31 can discharge the collected material into the discharge vertical pipe 33. A metal filter groove 32 is opened on the inner side of the left end of the discharge vertical pipe 33. The material falling in the discharge vertical pipe 33 can be effectively screened and discharged through the metal filter groove 32. A metal discharge tube plate 3 is fixedly connected to the lower left side of the discharge vertical pipe 33. The discharge vertical pipe 33 can discharge the screened material through the metal discharge tube plate 3. A receiving trough 35 is opened on the inner side of the lower end of the discharge vertical pipe 33. The unscreened material inside the discharge vertical pipe 33 will fall into the receiving trough 35 and then fall onto the first belt conveyor 2 for discharge. The receiving hopper 31 and the discharge vertical pipe 33 are fixedly connected to the inner wall of the solid waste recycling box 1 and can be stably installed. An air separation filter mechanism is fixedly connected through the upper right side of the discharge vertical pipe 33. The material inside the discharge vertical pipe 33 can be effectively screened by the air force blown by the air separation filter mechanism.

[0042] The receiving hopper 31, the discharge vertical pipe 33, and the solid waste recycling box 1 are fixedly provided with a metal discharge chamber on the left side, which can discharge the metal that has been adsorbed and screened, as well as the non-metallic materials that have been blown by the wind. The inner side of the metal discharge chamber is fixed to the solid waste recycling box 1 with a magnetic suction filter mechanism, which can be installed and placed accordingly for magnetic suction screening.

[0043] The magnetic filtration mechanism includes a plastic housing 41, which is made of plastic and therefore cannot be magnetized. An electromagnet 42 is fixedly connected to the inner groove of the plastic housing 41. The electromagnet 42 at the front end of the plastic housing 41 is magnetized when energized. If an iron is wrapped with a live power cord, the iron can be magnetized and attracted. The rear end of the electromagnet 42 passes through the plastic housing 41 and is fixedly connected to a power connection wire 4. The power connection wire 4 can be wrapped around the periphery of the electromagnet 42, so that the electromagnet 42 can be magnetized when energized. The magnetic attraction of the electromagnet 42 can pass through the metal filter tank 32 and attract the material falling into the discharge vertical pipe 33. The metal filter 32 is a square-hole area, allowing the crushed metal material to pass through efficiently. The metal filter 32 is located at the discharge vertical pipe 33 and is in the shape of an inverted L. This prevents the material from entering the metal filter 32 when it is falling vertically without external force. When the electromagnet 42 is energized, even the minimum magnetic attraction force can effectively pass through the metal filter 32 to attract the metal material falling inside the discharge vertical pipe 33. When the power is off, the material falls and can be discharged through the metal discharge tube plate 3. The power connection line 4 is electrically connected to the control box through the connection line, which is convenient for operation and control and can effectively control switching.

[0044] Example 3

[0045] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, to further better realize this utility model, the following configuration is specifically adopted: the air separation and filtration mechanism includes a conveying air duct 51, and a filter fan 5 is installed at the outer end of the conveying air duct 51 by screws. The filter fan 5 can convey gas into the conveying air duct 51. The other end of the conveying air duct 51 passes through the solid waste recycling box 1 and is fixedly connected to the discharge vertical pipe 33. The air inside the conveying air duct 51 can be blown into the discharge vertical pipe 33, and then the material falling into the discharge vertical pipe 33 can be screened by air. Non-metallic materials will pass through the metal filter tank 32, such as the separation of membrane fragments and heavy metal particles in lithium battery waste, and then fall into the metal discharge tube plate 3 for discharge. When air screening is used, magnetic screening stops.

[0046] The blowing and filtering position of the conveying air duct 51 corresponds to the position of the metal filter tank 32, which can be used for screening. The filter fan 5 can be controlled through the control box, which can effectively control the switching.

Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the control box, the first belt conveyor 2, the second belt conveyor 71, and the electromagnet 42 will not be explained in detail.

[0048] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
