Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of waste aluminum material recycling, in particular to a sorting system for aluminum waste materials. Background Art
[0002] Aluminum products are widely used in production and life. If a large number of waste aluminum products generated after use are not recycled, they are likely to cause environmental pollution and also lead to the loss of aluminum resources. At present, during the recycling of aluminum waste materials generated in the processing of aluminum products, due to the immaturity of the recycling process, the recovery rate of aluminum is relatively low, and other waste materials cannot be completely separated during the recycling process, resulting in secondary pollution when the aluminum waste materials are used again. Summary of the Invention
[0003] In order to solve the problems that the existing recovery rate of aluminum waste materials is relatively low and other waste materials cannot be completely separated during the recycling process, the utility model provides a sorting system for aluminum waste materials. The aluminum waste materials are crushed by a crusher, the first iron remover and the second iron remover separate the ferromagnetic impurities mixed in the aluminum waste materials, a suction fan sucks away the light waste materials (such as paper and plastic) in the crushed aluminum waste materials, and after the eddy current separator separates the aluminum, the recycling of the aluminum waste materials is realized, the recovery rate of aluminum in the aluminum waste materials is improved, and other waste materials are completely separated at the same time.
[0004] In order to achieve the above purpose, the technical solution of the utility model is as follows:
[0005] A sorting system for aluminum waste materials includes a conveying mechanism. Along the conveying direction of the conveying mechanism, a crusher, a first iron remover, a drum screen and a plurality of sorting mechanisms are sequentially arranged in the sorting system. The drum screen is used to sort out aluminum waste materials with different particle sizes. A plurality of discharge ports are arranged on the drum screen, and each discharge port is connected to the corresponding sorting mechanism through the conveying mechanism. Along the conveying direction of the conveying mechanism, each sorting mechanism is sequentially provided with a second iron remover, a suction fan and an eddy current separator. The first iron remover and the second iron remover are used to remove the ferromagnetic impurities mixed in the aluminum waste materials, and the eddy current separator is used to sort out the aluminum in the aluminum waste materials. The suction fan sucks away the light waste materials (such as paper and plastic) in the crushed aluminum waste materials. After the eddy current separator sorts out the aluminum in the aluminum waste materials, it is transported to the subsequent mechanism through the conveying mechanism.
[0006] Further, the drum screen includes a plurality of screen cylinders fixedly connected in sequence. The screen cylinders are provided with screen holes, and the aperture of the screen holes of the screen cylinders increases sequentially along the conveying direction of the materials. The screen cylinders are rotatably arranged in the drum screen. Under the action of centrifugal force and gravity, the aluminum waste materials with appropriate particle sizes will directly pass through the screen holes on the screen cylinders and fall onto the conveying mechanism through the discharge ports.
[0007] Furthermore, the multiple discharge ports provided on the drum sieve correspond to the multiple sieve drums one by one. The discharge ports are located on the lower side of the sieve drums, and each discharge port is connected to the corresponding sorting mechanism through a conveying mechanism. Separately conveying aluminum waste materials with different particle sizes to the corresponding sorting mechanisms is more conducive to the sorting of aluminum in the aluminum waste materials.
[0008] Furthermore, the drum sieve is inclined. The drum sieve and the sieve drum are inclined downward, which is conducive to the sorting of aluminum waste materials with different particle sizes in the sieve drum.
[0009] Furthermore, the discharge ends of the multiple sorting mechanisms are connected to a platform through a conveying mechanism, and the platform is used to place the aluminum sorted by the sorting mechanisms. The aluminum sorted from the aluminum waste materials on the platform is manually picked to separate the aluminum with a clean surface from the aluminum with an unclean surface.
[0010] Furthermore, there are two discharge ends on the platform. One discharge end is connected to a storage bin through a conveying mechanism, and the other discharge end is connected to a water washing mechanism through a conveying mechanism. The discharge end of the water washing mechanism is connected to a drying mechanism through a conveying mechanism, and the discharge end of the drying mechanism is connected to the storage bin through a conveying mechanism. The aluminum with an unclean surface is transported to the storage bin after being washed and dried.
[0011] Furthermore, the drying mechanism is a centrifugal dryer or an air dryer.
[0012] Furthermore, the conveying mechanism is a belt conveyor.
[0013] Through the above technical solutions, the beneficial effects of the present utility model are as follows:
[0014] 1. In the present utility model, the aluminum waste materials are crushed by a crusher, the first iron remover and the second iron remover separate the ferromagnetic impurities mixed in the aluminum waste materials, the air extractor sucks away the light waste materials (such as paper sheets and plastics) in the crushed aluminum waste materials, and after the eddy current separator separates the aluminum, the recycling of the aluminum waste materials is realized, improving the recovery rate of aluminum in the aluminum waste materials and completely separating other waste materials at the same time.
[0015] 2. In the present utility model, the aperture of the sieve holes of the sieve drums provided in the drum sieve gradually increases along the discharge direction, and separately conveying aluminum waste materials with different particle sizes to the corresponding sorting mechanisms is more conducive to the sorting of aluminum in the aluminum waste materials.

Specific embodiments
[0020] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments:
[0021] As Figures 1 to 3 shown, this embodiment provides a sorting system for aluminum waste, including a conveying mechanism 1. In this embodiment, the conveying mechanism 1 is a belt conveyor.
[0022] Further, the sorting system is sequentially provided with a crusher 2, a first iron remover 3, a drum screen 4 and a plurality of sorting mechanisms along the conveying direction of the conveying mechanism 1. The drum screen 4 is used to sort aluminum waste of different particle sizes. A plurality of discharge ports 5 are provided on the drum screen 4, and each discharge port 5 is connected to a corresponding sorting mechanism through the conveying mechanism 1; the aluminum waste is first crushed by the crusher 2 and then conveyed to the first iron remover 3 through the belt conveyor to separate the ferromagnetic impurities mixed in the aluminum waste, and then conveyed to the drum screen 4 through the belt conveyor.
[0023] Specifically, the drum screen 4 includes 3 screen cylinders fixedly connected in sequence. The screen cylinders are provided with screen holes, and the aperture diameters of the screen holes of the 3 screen cylinders increase sequentially along the conveying direction of the material. As Figure 2 shown, from left to right, the aperture diameters of the screen holes of the 3 screen cylinders increase sequentially.
[0024] In this embodiment, the 3 discharge ports 5 provided on the drum screen 4 correspond to the 3 screen cylinders one by one. The discharge ports 5 are located on the lower side of the screen cylinders, and each discharge port 5 is connected to a corresponding sorting mechanism through the conveying mechanism 1. The drum screen 4 is inclined. The screen cylinders are rotatably arranged in the drum screen 4, and the drum screen 4 and the screen cylinders are inclined downward. Under the action of centrifugal force and gravity, aluminum waste of different particle sizes will directly pass through the screen holes on the screen cylinders and fall onto the belt conveyor through the discharge ports 5, and the aluminum waste of different particle sizes is respectively conveyed to the corresponding sorting mechanisms for treatment, which is more conducive to the sorting of aluminum in the aluminum waste. During the working process of the drum screen 4, its screen cylinders rotate driven by an external power mechanism, and the discharge ports 5 do not rotate. In addition, it is the prior art, so it will not be elaborated here.
[0025] Furthermore, along the conveying direction of the conveying mechanism 1, each sorting mechanism is successively provided with a second iron remover 6, a suction fan 7, and an eddy current separator 8. The first iron remover 3 and the second iron remover 6 are used to remove ferromagnetic impurities mixed in the aluminum waste, and the eddy current separator 8 is used to separate the aluminum in the aluminum waste. The discharge ends of the three sorting mechanisms are all connected to a platform 9 through the conveying mechanism 1, and the platform 9 is used to place the aluminum separated by the sorting mechanism. The aluminum separated by the sorting mechanism on the platform 9 is manually sorted to separate the aluminum with a clean surface from the aluminum with an unclean surface.
[0026] Specifically, the platform 9 is provided with two discharge ends. The aluminum with a clean surface falls onto the conveying mechanism 1 through one of the discharge ends and is directly conveyed to the storage bin 10 for subsequent recycling. The aluminum with an unclean surface falls onto the conveying mechanism 1 through the other discharge end of the platform 9 and is conveyed to the water washing mechanism 11. In this embodiment, the water washing mechanism 11 is a water washing machine. The discharge end of the water washing mechanism 11 is connected to a drying mechanism 12 through the conveying mechanism 1. The cleaned aluminum is conveyed to the storage bin 10 through the discharge end of the drying mechanism 12 by the conveying mechanism 1.
[0027] In this embodiment, the drying mechanism 12 is a centrifugal dryer or an air dryer.
[0028] During use, the aluminum waste is first crushed by the crusher 2 and then conveyed to the first iron remover 3 by a belt conveyor to separate the ferromagnetic impurities mixed in the aluminum waste. Then it is conveyed to the drum screen 4 by the belt conveyor. Under the action of centrifugal force and gravity, the aluminum waste with different particle sizes in the drum screen 4 will directly pass through the screen holes on the screen cylinder and fall onto the belt conveyor through the discharge port 5, and the aluminum waste with different particle sizes is respectively conveyed to the corresponding sorting mechanisms for processing. The aluminum separated by the sorting mechanism is transported to the platform 9 by the belt conveyor for manual sorting. The aluminum with a clean surface falls onto the conveying mechanism 1 through one of the discharge ends of the platform 9 and is directly conveyed to the storage bin 10 for subsequent recycling. The aluminum with an unclean surface falls onto the conveying mechanism 1 through the other discharge end of the platform 9 and is conveyed to the water washing mechanism 11.
