A secondary sorting device for recycled solid waste slurry Technical Field

[0001] This utility model belongs to the field of solid waste recycling technology, specifically relating to a secondary sorting device for solid waste recycling slurry. Background Technology

[0002] In the process of recycling sand from foundry solid waste sand film shells for precision manufacturing, it is necessary to use crushers and ball mills to crush and grind the waste into granules, and then sort the slurry. The slurry sorting needs to be carried out multiple times. In the secondary sorting, large particles that are not fully crushed need to be screened out to ensure that the slurry contains specific sand particles. The secondary sorting needs to be carried out multiple times to ensure that the sand in the slurry is of uniform type. At the same time, the operation is convenient and the cost is controllable. This puts forward new requirements for the design of sorting equipment.

[0003] To address this issue, we designed a secondary sorting device for recycled solid waste slurry, providing an alternative technical solution. Summary of the Invention

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] As shown in Figures 1-3, a secondary sorting device for solid waste recycling slurry includes a support 1. A shaking table 2 with its right end tilted downwards is mounted on the support 1. A slurry tank is located below the right side of the shaking table 2. A metal collection box 5 is located at the right end of the slurry tank. A magnetic suction device 4 is located above the right drainage end of the shaking table 2. A first slide 6 is located below the rear end of the magnetic suction device 4. The first slide 6 guides the material from the magnetic suction device 4 into the metal collection box 5. A second slide 7 is located between the shaking table 2 and the slurry tank. An intercepting net 8 is located below the second slide 7.

[0018] This solution proposes a secondary sorting device for solid waste recycling, used to separate large solid particles that are not fully crushed and ferromagnetic metals, thereby further separating impurities in the slurry, ensuring the purity of the particles in the slurry, and screening for subsequent sorting and recycling, ultimately purifying valuable mullite and zircon sand; specifically, the slurry mixed with waste particles is fed from the left end of the shaking table 2. Under the vibration and gravity of the shaking table 2, the slurry is discharged from the right end of the shaking table 2 into the slurry tank 3. During this process, ferromagnetic metals are adsorbed and separated by the magnetic attraction device 4, and finally sent into the metal collection box 5 through the first slide 6, while the remaining large particles of materials enter the second slide 7 under the vibration of the shaking table 2. The large waste particles in the second slide are finally collected by the interception net 8 under the flushing of the slurry, thereby fully separating the large particles that cannot be crushed in the slurry;

[0019] In this scheme, the sorting device separates large particles from the slurry, which can further purify the sand particles in the slurry and improve the quality of the recovered special sand. At the same time, the magnetic attraction device 4 can recover ferromagnetic metals in the material, while the interception net 8 can recover non-ferromagnetic metals such as aluminum and titanium. This fully recovers valuable materials from the waste, realizes waste recycling and reuse, and improves economic efficiency while being green and environmentally friendly.

[0020] Furthermore, the magnetic attraction device 4 includes a mounting frame 16, a conveyor belt 14, a magnet 15, a motor 12, and a reducer 13. The bottom surface of the conveyor belt 14 is closely attached to the end face of the shaking table 2. The motor 12 and the reducer 13 are mounted on the top of the bracket 1 and are connected to the conveyor belt 14 for transmission. The magnet 15 is disposed between the upper and lower end faces of the conveyor belt 14. The length of the magnet 15 is shorter than the length of the conveyor belt 14, and the magnet 15 is close to the front end of the conveyor belt 14.

[0021] The magnetic suction device 4 is tilted to fully cover the upper surface of the shaker 2. Ferromagnetic metal materials pass over the shaker 2, and the magnet 15 of the magnetic suction device 4 attracts the materials and adheres them to the lower end of the conveyor belt 14. The motor 12 and the reducer 13 move, which can drive the materials magnetically attracted on the conveyor belt 14 to move forward. Since the length of the magnet 15 is shorter than the length of the conveyor belt 14, and the magnet 15 is closer to the front end of the conveyor belt 14 (closer to the end of the shaker 2), a magnetic vacuum will be formed at the rear end of the magnetic suction device 4 (closer to the end of the slurry tank 3), which will cause the attracted materials to fall into the first slide 6 and finally slide into the metal collection box 5 for collection.

[0022] Furthermore, the bottom of the shaker 2 is provided with a vibration mechanism, which includes a linear track 10, a linear motor 129 and a sliding block 11. The sliding block 11 is fixedly connected to the shaker 2, and the linear motor 129 drives the shaker 2 to perform linear reciprocating motion along the linear track 10.

[0023] Through this technical solution, the linear motor 129 drives the rocking table 2 to perform linear reciprocating motion, thereby realizing the vibration of the rocking table 2 and sending the slurry and the materials in the slurry to the slurry tank 3 for screening.

[0024] Furthermore, the second slide 7 is inclined, and the cross-section of the second slide 7 is U-shaped.

[0025] Furthermore, the intercepting net 8 is located inside the slurry pool and is detachably connected.

[0026] After the magnetic suction device 4 separates the ferromagnetic metal, other large particles will enter the second slide 7 under the vibration of the shaking table 2, and then slide down from the second slide 7 into the interior of the intercepting net 8. The intercepting net 8 can be removed so that the material collected by the intercepting net 8 can be taken out to collect valuable materials. The intercepting net 8 is set inside the slurry tank 3. During the process of the material falling into the intercepting net 8, the slurry in the slurry tank 3 can play a buffering role to prevent the intercepting net 8 from being damaged, while normal sand particles can return to the slurry tank 3 through the mesh of the intercepting net 8.

[0027] Working principle: The slurry mixed with waste particles is fed into the shaking table 2 from the left end. Under the vibration and gravity of the shaking table 2, the slurry is discharged into the slurry tank 3 from the right end of the shaking table 2. During this process, ferromagnetic metals are adsorbed and separated by the magnetic attraction device 4 and finally sent into the metal collection box 5 through the first slide 6. The remaining large particles are sent into the second slide 7 under the vibration of the shaking table 2. The large waste particles in the second slide are finally collected by the interception net 8 under the washing of the slurry, thus fully separating the large particles that cannot be crushed in the slurry. The sorting device separates the large particles in the slurry, which can further purify the sand particles in the slurry and improve the quality of the recovered special sand. At the same time, the magnetic attraction device 4 can recover the ferromagnetic metals in the material, while the interception net 8 can recover non-ferromagnetic metals such as aluminum and titanium. Thus, valuable materials in the waste are fully recovered, realizing the recycling and reuse of waste. It is environmentally friendly and improves economic efficiency. The sorting device of this scheme is easy to assemble and maintain, has a high degree of material sorting, and has excellent performance.
