Description

Technical Field

[0001] This utility model relates to the field of aluminum slag recycling, and more specifically, to an aluminum slag vibrating screen sorting and recycling device. Background Technology

[0002] Aluminum slag is a solid waste generated during aluminum smelting, casting, and recycled aluminum production. Its main components are metallic aluminum (40%-60%), alumina (Al₂O₃), and small amounts of metal oxides and salts (such as chlorides and fluorides) including iron, silicon, and magnesium. Based on its source, it can be divided into primary aluminum slag (hot-state dross with a high aluminum content) and secondary aluminum slag (cold-state residue with an aluminum content reduced to 3%-9%). Secondary aluminum slag is classified as hazardous waste due to its presence of harmful components such as aluminum nitride (which releases ammonia upon contact with water) and fluorides. The generation of aluminum slag is closely related to processes such as electrolysis and smelting. For example, during aluminum electrolysis, dross forms loose aluminum ash due to oxidation and impurities, while in the casting process, slag lumps are produced due to metal oxidation and the addition of flux.

[0003] The discharge port of the existing filter residue screening device is not fast enough, which causes large pieces of aluminum slag to accumulate. This results in large pieces of aluminum slag accumulating on the screen, thus affecting work efficiency. In addition, the aluminum slag falling on the screen causes a lot of noise. Therefore, we have made improvements and proposed an aluminum slag vibrating screen classification and recycling treatment device. Utility Model Content

[0033] Example:

[0034] like Figure 1-6 As shown, this embodiment proposes an aluminum slag vibrating screen classification and recycling treatment device, including a base 1, a support 2 on the base 1, and a transmission mechanism on the support 2. The transmission mechanism is used to drive the receiving plate 3 to reciprocate and vibrate to achieve screening. The receiving plate 3 is arranged above the support 2, and a first discharge hopper 4 is integrally formed on the receiving plate 3. Small particles fall into the receiving plate 3 through the screen holes and are discharged through the first discharge hopper 4. A screening plate 5 is connected to the top of the receiving plate 3, and a second discharge hopper 6 is integrally formed on the screening plate 5. Large particles slide along the inclined surface of the screening plate to the second discharge hopper 6. A protective plate 7 is fixedly installed on the top of the base 1. A sound-absorbing plate 8 is adhered to the inner wall of the protective plate 7. The sound-absorbing plate 8 on the inner side of the protective plate 7 can reduce the impact noise of aluminum slag by 10-15 decibels, meeting industrial noise standards. A bracket 9 is fixedly installed on the protective plate 7. A drive mechanism is installed on the bracket 9. A rotating roller 10 is installed at the output end of the drive mechanism. The drive mechanism drives the rotating roller 10 to rotate. A deflector plate 11 is fixedly installed on the rotating roller 10. The rotation of the rotating roller 10 drives the deflector plate 11 to periodically agitate large pieces of aluminum slag, forcing them through the second discharge hopper 6, thus solving the problem of easy clogging of traditional screens. This aluminum slag screening device can not only classify and screen aluminum slag, but also reduce the noise of aluminum slag falling on the screen. In addition, it has an auxiliary discharge function to effectively prevent the accumulation of large pieces of aluminum slag on the screen.

[0035] The transmission mechanism includes a first motor 12 fixedly mounted on the support 2. An eccentric disk 13 is fixedly mounted on the output end of the first motor 12. The first motor 12 drives the eccentric disk 13 to rotate. A connecting rod 14 is rotatably connected to the eccentric disk 13. The eccentric disk 13 drives the connecting rod 14. The other end of the connecting rod 14 is rotatably connected to the receiving plate 3, so that the circular motion is converted into the reciprocating linear motion of the receiving plate 3 and the screening plate 5 through the connecting rod 14.

[0036] The drive mechanism includes a second motor 17 fixedly mounted on the bracket 9. The output end of the second motor 17 is fixedly connected to the rotating roller 10, and the second motor 17 drives the rotating roller 10 to rotate.

[0037] The bottom of the support 2 is provided with a sliding groove 20. An L-shaped plate 15 is fixedly installed on the side wall of the receiving plate 3. A slider 16 is fixedly installed on the L-shaped plate 15. The slider 16 on the side wall of the receiving plate cooperates with the sliding groove 20 of the support to ensure stable vibration direction and avoid screen body deviation.

[0038] A switch assembly 18 is provided on the front of the guard plate 7. The switch assembly 18 is electrically connected to both the first motor 12 and the second motor 17. The switch assembly 18 is used to start the two motors.

[0039] Specifically, when this aluminum slag vibrating screen sorting and recycling device is in use: the first motor 12 is started to drive the eccentric disk 13 to rotate. The eccentric wheel 13 drives the connecting rod 14, so that the circular motion is converted into the reciprocating linear motion of the receiving plate 3 and the screening plate 5 through the connecting rod 14. The receiving plate 3 and the screening plate 5 are connected by a spring (the spring is wrapped with a rubber sleeve), thus realizing vibration. The slider 16 on the side wall of the receiving plate cooperates with the support groove 20 to ensure the vibration direction is stable and to prevent the screen body from deviating.

[0040] Aluminum slag falls into screening plate 5, small particles fall through the screen holes into receiving plate 3, and are discharged through first discharge hopper 4. Large particles slide along the inclined surface of screening plate to second discharge hopper 6, where a container is placed at the bottom of discharge hopper to receive them. At this time, second motor 17 drives roller 10 to rotate, and push plate 11 periodically pushes large pieces of aluminum slag, forcing them to pass through second discharge hopper 6, thus solving the problem of easy clogging of traditional screens.

[0041] The sound-absorbing panel 8 on the inner side of the guard plate 7 can reduce the impact noise of aluminum slag by 10-15 decibels, which meets the industrial noise standard.

[0042] Example 2:

[0043] The transmission mechanism includes a first motor 12 fixedly mounted on the support 2. An eccentric disk 13 is fixedly mounted on the output end of the first motor 12. The first motor 12 drives the eccentric disk 13 to rotate. A connecting rod 14 is rotatably connected to the eccentric disk 13. The eccentric disk 13 drives the connecting rod 14. The other end of the connecting rod 14 is rotatably connected to the receiving plate 3, so that the circular motion is converted into the reciprocating linear motion of the receiving plate 3 and the screening plate 5 through the connecting rod 14.

[0044] The first motor 12 is started to drive the eccentric disk 13 to rotate. The eccentric wheel 13 drives the connecting rod 14, so that the circular motion is converted into the reciprocating linear motion of the receiving plate 3 and the screening plate 5 through the connecting rod 14. The receiving plate 3 and the screening plate 5 are connected by a spring, and the rubber sleeve can be removed to achieve vibration. The slider 16 on the side wall of the receiving plate cooperates with the support groove 20 to ensure the vibration direction is stable and to avoid the screen body from deviating.

[0045] All technical features in this embodiment can be freely combined according to actual needs.
