[0002] Municipal solid waste produces slag after incineration in an incinerator, which requires further processing. In typical slag treatment, water is added to the material, and particle size is classified to create a slurry with a concentration of 30%. The slurry particles smaller than 2.5mm move gradually during screening, and the washing water passes through the screen holes and falls into a settling bin for collection. After settling, the washing water is further treated. Materials larger than 2.5mm enter an eddy current separator. However, this process cannot directly remove the aluminum metal.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0019] like Figure 1 and Figure 2As shown, the wet sorting and fine sand aluminum separation equipment for municipal solid waste incinerator slag includes: aluminum outlet 1, settling hopper 2, eddy current separator 3, spiral sand washer 4, vibrating screen 5, platform frame 6, double-layer eddy current separator 7, feeding mechanism 8, and dewatering screen 9.

[0020] Platform frame 6 serves as the overall support for the equipment, and is divided into three layers vertically. The vibrating screen 5 is installed on the top layer of platform frame 6. The eddy current separator 3 is installed in the middle layer of platform frame 6, and the spiral sand washer 4 is installed between the vibrating screen 5 and the eddy current separator 3. There are two double-layer eddy current separators 7, each installed in the middle layer of platform frame 6. The dewatering screen 9 is installed at the bottom layer of platform frame 6. The settling hopper 2 is installed in the middle layer of platform frame 6 and connected to the vibrating screen 5 via a feed pipe. In actual operation, the slurry enters the vibrating screen 5 and is screened by the vibration of the screen. The screen plate of the vibrating screen 5 is divided into four sections, with openings of 0-1.5mm, 1.5-2.5mm, 2.5-6mm, and 6mm respectively. The slurry is progressively screened through these four sections. When the slurry passes through the 0-1.5mm sieve openings in the first-stage sieve area, particles smaller than or equal to 1.5mm separate from this area and fall into the settling hopper 2. The material oversizes into the 1.5-2.5mm sieve openings in the second-stage sieve area, with the 1.5-2.5mm particles entering the spiral sand washer 4. The spiral sand washer 4 consists of a head and a tail section. Fine sand is separated from the slurry in the spiral sand washer 4 and gradually pushed into the eddy current separator 3 as the spiral blades rotate. The eddy current separator 3 separates the metallic aluminum mixed in the material and outputs it through the aluminum outlet 1 installed at the discharge end of the eddy current separator 3. This process yields finely crushed aluminum and finished sand. The remaining slurry particles with diameters of 2.5-6mm and larger than 6mm enter two double-layer eddy current separators 7 for separation, resulting in finished fine sand and metallic aluminum. The settling hopper 2 is connected to the dewatering screen 9 through a pipe. The dewatering screen 9 can dewater and screen the slurry with the smallest particle size to obtain fine sand.

[0021] refer to Figure 2 The feeding mechanism 8 is installed on the rear side of the platform frame 6. The feeding mechanism 8 is used to lift and feed the slurry and to discharge it intermittently, so as to avoid a large amount of slurry accumulating on the vibrating screen 5.

[0022] refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 The feeding mechanism 8 includes: a cylinder 81, a feeding port 82, a lifting screw 83, a motor 84, a gear 85, a discharge cylinder 86, an outlet 87, a flow control plate 88, a turntable 89, a first lever 810, a swing groove 811, a slide rail 812, and a second lever 813.

[0023] A cylinder 81 is installed on the rear side of the platform frame 6, and is inclined forward from top to bottom. A feeding port 82 is located on the cylinder 81. A lifting screw 83 is rotatably installed inside the cylinder 81, and its rotation lifts the material from bottom to top. A motor 84 is installed at the top of the cylinder 81. There are two gears 85, each rotatably installed in the inner cavity at the top of the cylinder 81, and the two gears 85 mesh with each other. One gear 85 is connected to the lifting screw 83. Turning on the motor 84 drives one gear 85 to rotate, causing the lifting screw 83 and the other gear 85 to rotate together. A discharge cylinder 86 is installed at the top of the cylinder 81, and is inclined downward from front to back. An outlet 87 is located at the free end of the discharge cylinder 86, allowing the material to move towards the outlet 87 by gravity. A flow control plate 88 is rotatably installed in the discharge cylinder 86. A turntable 89 is installed at the bottom end of the gear 85 that is not directly connected to the motor 84. The first lever 810 is mounted on the lower surface of the turntable 89. The swing groove 811 is rotatably mounted on the top of the discharge cylinder 86, and the first lever 810 extends into the swing groove 811. A slide rail 812 is formed on the upper surface of the discharge cylinder 86; the slide rail 812 is arc-shaped and coaxial with the rotation center of the flow control plate 88. The second lever 813 is mounted on the top of the flow control plate 88, and the second lever 813 passes through the slide rail 812 and extends into the swing groove 811.

[0024] The working principle of this structure is as follows: Turning on the motor 84 drives the connected gear 85 and lifting screw 83 to rotate. Slurry is fed into the feed port 82, and the lifting screw 83 lifts the slurry into the discharge cylinder 86. During this process, the two gears 85 rotate synchronously, the turntable 89 rotates accordingly, and the first lever 810 moves in a circular motion, which in turn causes the swing groove 811 to swing back and forth. The swing of the swing groove 811 drives the second lever 813 to move the flow control plate 88 to swing in the discharge cylinder 86. When the two ends of the flow control plate 88 are in contact with the discharge cylinder 86, it can prevent material from falling. The swing of the flow control plate 88 achieves intermittent feeding, preventing the slurry from continuously falling onto the vibrating screen 5 and avoiding large accumulation that could disrupt the smooth operation of the screening process.

[0025] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
