Description

Technical Field

[0001] This utility model belongs to the field of electrolytic aluminum production technology, and more specifically, relates to an electrolytic aluminum waste slag recycling device. Background Technology

[0002] In the electrolytic aluminum production process, a large amount of waste residue is usually generated. This waste residue contains a certain proportion of reusable materials. In order to improve resource utilization and reduce production costs, it is necessary to recycle it effectively. In practical applications, the recycling process often requires screening the waste residue first in order to classify materials of different particle sizes or compositions. Vibrating screen is one of the key pieces of equipment to complete this process, and its performance directly affects the sorting effect and processing efficiency.

[0003] Currently, in the field of vibrating screens commonly used in electrolytic aluminum slag treatment, it is often necessary to replace screen plates with different apertures or specifications to adapt to different working conditions or changes in slag particle size. As described in patent CN216460035U, the filter screens in traditional vibrating screens are mostly fixed with bolts, requiring the disassembly of a large number of fasteners during replacement, which is cumbersome, time-consuming, and labor-intensive, affecting the continuous production rhythm. Although this patent proposes a quick installation structure based on insert rods and limiting plates, which improves the disassembly and assembly efficiency to some extent, whether its structure can withstand the heavy load and continuous vibration in electrolytic aluminum slag screening still needs to be verified, and it does not fully consider the need for quick adaptation of screen plates of various specifications.

[0004] Currently, most vibrating screening devices suffer from cumbersome operation, insecure fixing, and low replacement efficiency in screen plate replacement, which not only affects operational efficiency but also poses certain safety hazards. Furthermore, existing technologies are mostly designed for general vibration scenarios and have not been structurally optimized for the highly corrosive and unevenly distributed particle characteristics of electrolytic aluminum slag, generally resulting in low screening efficiency, high labor intensity for screen plate replacement, and poor equipment adaptability. Therefore, there is an urgent need for a vibrating screening device specifically designed for the recycling of electrolytic aluminum slag, offering high-efficiency screening and convenient screen plate replacement.

Through the elastic force of the pressing spring 34, the pressing block 30 drives the limiting rod 31 to reset in the limiting hole 33, realizing the automatic restoration function of the mechanism.

[0032] The inner wall of the fixed sleeve 9 is provided with a positioning strip 35, and the outer wall of the insertion rod 8 is provided with a positioning groove 36. Multiple sets of positioning strips 35 and positioning grooves 36 are provided and slidably connected. Through the sliding cooperation between the positioning strips 35 and the positioning grooves 36, the insertion rod 8 is ensured to be quickly and accurately aligned during the insertion process.

[0033] Each of the multiple sets of snap-fit ​​rods 10 has a guide groove 37. The top of the fixed sleeve 9 is provided with a guide block 38. There are multiple sets of guide blocks 38, which are slidably connected to the multiple sets of guide grooves 37. A return spring 39 is connected between the bottom surface of the multiple sets of guide blocks 38 and the inner wall of the guide groove 37. Under the action of the return spring 39, the guide block 38 automatically returns to its position along the guide groove 37, ensuring the guiding accuracy and stability of the snap-fit ​​rod 10.

[0034] In this embodiment, during use, the waste residue is placed in the sieve box 5. The motor 16 is started and drives the eccentric wheel 17 to rotate through the transmission assembly 18. The eccentric wheel 17 drives the connecting rod 19 to rotate along the eccentric shaft and repeatedly pushes and pulls the slider 4 to slide along the movable groove 3. The slider 4 drives the sieve box 5 to move repeatedly to screen the waste residue. The dried waste residue falls into the collection box 23 through the inclined plate 22. When it is necessary to replace different sieve plates 6, the rotating sleeve 27 drives multiple sets of support rods 28 to rotate, causing multiple sets of arc rods 26 to disengage from the sliding hole 29, releasing the limit on the connecting sleeve 24. Multiple sets of reset springs 39 pull the snap-fit ​​rod 10 to slide through the guide groove 37 along the guide block 38 and disengage from the insertion hole 11, releasing the snap-fit ​​on the insertion rod 8. Then the insertion rod 8 is pulled out of the fixing sleeve 9 and the through hole 7, thus releasing the fixation on the sieve box 5.

[0035] More specifically, when the sieve box 5 needs to be installed, the insertion rod 8 is inserted into the through hole 7 and the sieve box 5, and then the fixing sleeve 9 is inserted into the insertion rod 8. The connecting sleeve 24 is pushed to pull the pressure plate 14 through the connecting frame 13 and the slide rod 12, so that it pushes the multiple sets of snap-fit ​​rods 10 to be inserted into the insertion hole 11. The multiple sets of snap-fit ​​rods 10 slide along the guide block 38 through the guide groove 37 and stretch the reset spring 39. At the same time, the rotating sleeve 27 is rotated to drive the multiple sets of support rods 28 and the extrusion block 30 to move. The multiple sets of extrusion blocks 30 compress the extrusion spring 34. When the connecting sleeve 24 slides to the lowest end, the multiple sets of arc rods 26 are parallel to the multiple sets of sliding holes 29 respectively. The rotating sleeve 27 is released, and the extrusion block 30 is pushed by the multiple sets of extrusion springs 34 to rotate the rotating sleeve 27, so that the multiple sets of arc rods 26 are inserted into the sliding hole 29, limiting the connecting sleeve 24.

[0036] The working principle of this utility model device is as follows: When in use, the waste residue is placed in the sieve box 5. The motor 16 is started and drives the eccentric wheel 17 to rotate through the transmission component 18. The eccentric wheel 17 drives the connecting rod 19 to rotate along the eccentric shaft and repeatedly pushes and pulls the slider 4 to slide along the movable groove 3. The slider 4 drives the sieve box 5 to move repeatedly to screen the waste residue. The dried waste residue falls into the collection box 23 through the inclined plate 22. When it is necessary to replace different sieve plates 6, the rotating sleeve 27 drives multiple sets of support rods 28 to rotate, causing multiple sets of arc rods 26 to disengage from the sliding hole 29, releasing the limit on the connecting sleeve 24. The reset spring 39 pulls the snap-fit ​​rod 10 to slide along the guide block 38 through the guide groove 37 and disengage from the insertion hole 11. Then the insertion rod 8 is pulled out of the fixing sleeve 9 and the through hole 7, thus releasing the fixation of the sieve box 5.

[0037] When the sieve box 5 needs to be installed, insert the insertion rod 8 into the through hole 7 and the sieve box 5, put the fixing sleeve 9 onto the insertion rod 8, push the connecting sleeve 24 through the connecting frame 13 and the slide rod 12 to pull the pressure plate 14 so that the snap-fit ​​rod 10 is inserted into the insertion hole 11. Multiple sets of snap-fit ​​rods 10 slide along the guide block 38 through the guide groove 37 and stretch the return spring 39. At the same time, rotate the rotating sleeve 27 to drive multiple sets of support rods 28 and the pressing block 30 to move. Multiple sets of pressing blocks 30 compress the pressing spring 34. When the connecting sleeve 24 slides to the lowest end, multiple sets of arc rods 26 are parallel to multiple sets of sliding holes 29 respectively. Release the rotating sleeve 27, and push the pressing block 30 through the multiple sets of pressing springs 34 to rotate the rotating sleeve 27, so that multiple sets of arc rods 26 are inserted into the sliding hole 29, thus completing the limiting of the connecting sleeve 24.

For all the fixed connections mentioned above, welding is preferred.
