Description

Technical Field

[0001] This utility model relates to the field of aluminum recycling technology, specifically to a vibrating screen aluminum ash slag aluminum recycling device. Background Technology

[0002] The vibrating screen aluminum ash slag aluminum recovery device is a specially designed equipment for effectively recovering metallic aluminum from aluminum ash slag. This device uses the principle of vibrating screening to achieve effective separation of aluminum ash slag and metallic aluminum by utilizing the different movement trajectories of materials of different particle sizes on the screen surface. During the screening process, metallic aluminum can be effectively screened out due to its high density and specific physical properties, while impurities such as aluminum ash slag are removed. This recovery device not only improves the recovery rate of metallic aluminum, but also realizes the reuse of aluminum resources, reduces environmental pollution, and has high economic and environmental benefits.

[0003] Chinese patent CN215844195U discloses a vibrating screen machine. When the vibrator is running, it transmits vibrations to the ground. The soundproof cover, the first soundproof board, and the second soundproof board reduce noise to the greatest extent.

[0004] During the screening process, the area of ​​the discharge hopper where the material falls cannot be adjusted, and it cannot be adjusted according to different screening needs. It cannot flexibly meet the different requirements of vibrating screen for aluminum ash slag, and its applicability is poor. Utility Model Content

[0005] The purpose of this invention is to provide a vibrating screen for recovering aluminum ash slag and metallic aluminum. The second filter grid slides laterally along the movable rail via a sliding block. This sliding allows the second filter grid, which overlaps with the first filter grid, to move laterally. As the second filter grid moves laterally, it restricts the fallable area of ​​the first filter grid. Through the overlap and positional offset between the second and first filter grids, the fall of aluminum ash slag of different sizes can be restricted, adapting to different screening requirements and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vibrating screen for recovering aluminum ash slag and metallic aluminum, comprising a first filter grid, a second filter grid at the lower end of the first filter grid, sliding blocks welded to both the front and rear ends of the second filter grid, a fixing ring surrounding the outer side of the first filter grid, a transmission frame welded to both the front and rear ends of the fixing ring, a movable rail recessed inside the transmission frame facing the sliding block, and the sliding block slidingly embedded inside the movable rail, the second filter grid sliding into the movable rail facilitates its fixation, and similarly, the second filter grid can be directly fixed after sliding within the movable rail.

[0007] Preferably, the sliding block has a second fixing hole in its internal recess, and a first fixing hole is evenly distributed laterally at one end of the second fixing hole. The reserved second fixing hole and the first fixing hole facilitate the bolt to pass through, so that the second filter grid mesh can be fixed after the bolt is passed through.

[0008] Preferably, the lower end of the fixing ring is provided with a second discharge pipe, and the material falling through the screening can be directly discharged to the corresponding position.

[0009] Preferably, the first filter grid is welded and fixed to the fixing ring. The fixing ring can prevent material falling from the edge of the first filter grid, thus preventing the material from being unable to be screened smoothly.

[0010] Preferably, a guide vane is provided on one side of the upper end of the fixing ring. The reserved guide vane facilitates the smooth collection and flow of the retained material into the guide vane when the object is poured.

[0011] Preferably, a second rotating shaft is provided on one side of the guide vane, and a vibrator is provided inside the second rotating shaft. The vibration of the vibrator can facilitate the screening of the material at the upper end.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention uses a vibrator to shake the material at the top of the first filter grid. This shaking separates aluminum ash and metallic aluminum. The aluminum ash falls due to the shaking and its own weight, allowing it to pass directly through the first filter grid. However, the second filter grid slides laterally along a movable track via a sliding block. This sliding movement allows the second filter grid, which overlaps with the first filter grid, to move laterally, thus limiting the area where the first filter grid can fall. Through the overlap and positional offset between the second and first filter grids, the falling of aluminum ash of different sizes can be restricted. By restricting the falling of aluminum ash, the corresponding metallic aluminum is retained at the top of the first filter grid. Users can flexibly adjust this according to the size of the items to be screened to adapt to different screening needs. Attached Figure Description

[0022] The present invention will be further described below with reference to specific embodiments.

[0023] like Figure 1 and Figure 2 As shown, the vibrating screen aluminum ash slag and metallic aluminum recovery device of this embodiment includes a first filter grid 5. The first filter grid 5 is provided with a sound insulation cover 1 on the outside. A rotatable baffle 10 is provided on one side of the upper end of the sound insulation cover 1. After the baffle 10 is rotated, the material input area can be exposed. After the baffle 10 is rotated, the material can be input. After the material is input into the sound insulation cover 1 and falls on the upper end of the first filter grid 5, the first filter grid 5 can directly screen aluminum ash slag and metallic aluminum. The aluminum ash slag can directly pass through the first filter grid 5 and fall down.

[0024] In order to receive the screened aluminum ash slag, a fixing ring 4 is provided around the outside of the first filter grid 5. The fixing ring 4 restricts the material received at the upper end of the first filter grid 5 to prevent excess material from falling directly from the edge of the first filter grid 5. The first filter grid 5 is welded and fixed to the fixing ring 4. A second discharge pipe 3 is provided at the lower end of the fixing ring 4. The lower end of the second discharge pipe 3 extends to one side outside the sound insulation cover 1. The aluminum ash slag that passes through the first filter grid 5 and falls can be received and discharged by the first discharge pipe 2.

[0025] Furthermore, in order to collect the metallic aluminum that remains on the upper end of the first filter grid 5, a guide plate 6 is provided on one side of the upper end of the fixing ring 4, and a second rotating shaft 8 is provided on one side of the guide plate 6. A vibrator 9 is provided inside the second rotating shaft 8, and the outer wall of the vibrator 9 is fixedly connected to the side of the guide plate 6 by bolts. After the material to be screened falls on the upper end of the first filter grid 5, the vibration generated by the start of the vibrator 9 will assist in the screening of aluminum ash and metallic aluminum.

[0026] It is worth mentioning that a support rod 17 is provided at the lower end of the second rotating shaft 8. The support rod 17 and the second rotating shaft 8 are rotatably connected through the first rotating shaft 7. The second rotating shaft 8 can tilt around the first rotating shaft 7 to tilt the aluminum metal trapped at the upper end of the first filter grid 5. A first discharge pipe 2 is provided on the other side of the support rod 17 and is welded and fixed to the soundproof cover 1. After the first filter grid 5 is rotated and tilted, the trapped aluminum metal can fall down and be received by the first discharge pipe 2 and discharged to the outside of the soundproof cover 1.

[0027] In order to adjust the falling area of ​​the first filter screen 5, adjustments are made to adapt to different screening requirements, such as... Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, a second filter grid 11 is provided at the lower end of the first filter grid 5. The lower end of the first filter grid 5 can be restricted by the lateral movement of the second filter grid 11. The intersection of the first filter grid 5 and the second filter grid 11 can limit the area where aluminum ash can fall. The continuous lateral movement of the second filter grid 11 can be gradually adjusted and adapted to the screening requirements.

[0028] To facilitate adjustment of the second filter mesh 11, sliding blocks 15 are provided at both the front and rear ends of the second filter mesh 11, and the sliding blocks 15 are welded and fixed to the second filter mesh 11. Transmission frames 12 are provided at both the front and rear ends of the fixing ring 4, and the transmission frames 12 are welded and fixed to the fixing ring 4. Figure 4 As shown, the transmission frame 12 has a recessed movable rail 13 facing the sliding block 15, and the sliding block 15 is slidably embedded in the movable rail 13. The sliding block 15 sliding in the movable rail 13 facilitates the suspension of the second filter grid 11.

[0029] Furthermore, in order to fix the sliding block 15, a second fixing hole 16 is provided in the recess of the sliding block 15. One end of the second fixing hole 16 has first fixing holes 14 evenly distributed laterally. The reserved first fixing holes 14 can facilitate the bolt to pass through and fix the corresponding position. After the sliding block 15 moves laterally, until the corresponding first fixing hole 14 overlaps with the second fixing hole 16, the fixing of the sliding block 15 and the adjusted second filter grid 11 can be completed.

[0030] The second fixing hole 16 and the first fixing hole 14 are fixedly connected by bolts. The outside of the bolt is threaded into the position of the second fixing hole 16, and the bolt can be used to fix the second filter grid 11 after adjustment.

[0031] Working Principle: When using the device to vibrate and screen aluminum ash and metallic aluminum, the aluminum ash and metallic aluminum to be screened are fed into the soundproof cover 1 from the baffle 10 position. Inside the soundproof cover 1, they fall onto the upper end of the first filter grid 5. The start of the vibrator 9 generates vibration, which, driven by the second rotating shaft 8 and the fixed ring 4, screens the material. The screened material falls and is received and discharged by the second discharge pipe 3. The metallic aluminum remaining on the upper end of the first filter grid 5 can be tilted after the second rotating shaft 8 rotates around the first rotating shaft 7, allowing the retained metallic aluminum to be fed into the first discharge pipe 2 position. The metallic aluminum is received and discharged by the first discharge pipe 2. Adjusting the position of the first filter grid 5 allows the material to fall... When the material is large, the sliding blocks 15 at both ends of the second filter grid 11 slide laterally within the movable rail 13. This sliding can restrict the first filter grid 5, adjusting the space where the material can fall to adapt to different screening requirements. After adjusting the sliding blocks 15, the bolts can be inserted through the first fixing hole 14 and the second fixing hole 16 to fix the sliding blocks 15. The second filter grid 11 can rotate with the rotation of the first filter grid 5. Even if the material gets stuck between the first filter grid 5 and the fixing ring 4, the rotation of the first filter grid 5 and the second filter grid 11 can tilt the material and discharge it.
