Description

Technical Field

[0001] This utility model relates to the field of aluminum ash processing technology, specifically to a grinding device for calcining aluminum ash. Background Technology

[0002] Aluminum ash is a byproduct of aluminum production. Specifically, it is the scum or skimmed residue that floats on the surface of molten aluminum during the smelting process of electrolytic aluminum, cast aluminum, and recycled aluminum. During smelting, aluminum ash and aluminum particles form a symbiotic mixture, which often needs to be ground to separate them. Because the pure aluminum particles in aluminum ash have good plasticity, after grinding, the small aluminum ash particles are crushed into larger aluminum particles, making them easier to separate during screening. Through grinding, aluminum particles and aluminum ash can be better separated, improving screening efficiency and purity, thus providing better raw materials for subsequent calcination.

[0003] In existing technology, when aluminum ash is ground, due to its plasticity, it is discharged through the feeding hole of the grinding device. Since the inner diameter of the feeding hole is fixed, the pure aluminum particles in the aluminum ash will extend during grinding. After the extension, the size of the larger pure aluminum particles will exceed the inner diameter of the feeding hole. At this time, the feeding hole will be blocked by the larger pure aluminum particles, and the aluminum powder in the grinding device cannot be completely discharged through the feeding hole, thus affecting its performance. Utility Model Content

[0029] 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.

[0030] Example: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A grinding device for calcining aluminum ash includes: a frame 1, with two bearing seats 2 fixedly mounted on the top surface of the frame 1, and a grinding cylinder 5 rotatably connected between the two bearing seats 2; a mounting frame 4 fixedly mounted on the top surface of the frame 1, a first motor 6 fixedly mounted on the top surface of the mounting frame 4, and a steering gear 7 fixedly mounted on the top surface of the mounting frame 4, one end of the drive shaft of the first motor 6 being fixedly mounted to the connecting shaft of the steering gear 7, and the rotating shaft of the steering gear 7 being belt-driven connected to the grinding cylinder 5; a positioning frame 10 fixedly mounted inside the frame 1, with several connecting seats 16 rotatably connected to the top surface of the positioning frame 10, a first spring 19 movably sleeved inside the connecting seats 16, a connecting column 20 slidably connected inside the connecting seats 16, and a steel brush head 12 fixedly mounted on the top surface of the connecting column 20; a drive assembly is provided inside the frame 1 for driving the multiple steel brush heads 12 to rotate; and a collection tray 8 is slidably connected inside the frame 1. During use, the operator places the aluminum ash block to be ground against the grinding tray. The grinding balls are placed inside the grinding cylinder 5. The operator then uses the first motor 6, and the drive shaft of the first motor 6 rotates, which in turn drives the shaft of the steering gear 7 to rotate. Under the action of belt drive, the grinding cylinder 5 rotates accordingly. The grinding balls inside the grinding cylinder 5 roll and continuously impact the aluminum ash blocks, breaking them into smaller pieces, thereby achieving the effect of ball grinding the aluminum ash blocks. When the grinding cylinder 5 rotates, the operator uses the drive assembly to rotate multiple steel brush heads 12. The first spring 19 inside the connecting seat 16 provides an upward elastic force, causing the steel brush heads 12 to continuously contact the surface of the grinding cylinder 5. Then, the steel brushes on the surface of the steel brush heads 12 enter the interior of the feeding holes on the surface of the grinding cylinder 5, thereby clearing the blockage of aluminum ash inside. After grinding, the aluminum ash falls through the holes on the surface of the grinding cylinder 5 into the interior of the collection tray 8, thus achieving the effect of facilitating ball grinding of aluminum ash and preventing blockage during aluminum ash feeding.

[0031] Based on the above embodiments, refer to Figure 3 , Figure 4 , Figure 6 and Figure 7The drive assembly includes: a rotating shaft 28, rotatably connected inside the frame 1; a driven bevel gear 21 fixedly sleeved on the outer circular wall of the rotating shaft 28; a second motor 11 fixedly mounted on one side of the frame 1; a driving bevel gear 29 fixedly mounted on one end of the drive shaft of the second motor 11; the driving bevel gear 29 meshing with the driven bevel gear 21; a driving pulley 13 fixedly sleeved on the outer circular wall of the rotating shaft 28; driven pulleys 15 fixedly sleeved on the outer circular walls of several connecting seats 16; and a transmission belt 14 between the driving pulley 13 and the driven pulley 15, connecting them via the transmission belt 14. When the operator needs to drive multiple steel brush heads 12 to rotate, the operator uses the second motor 11, which in turn drives the driving bevel gear 29 to rotate. Then, under the meshing transmission action of the driving bevel gear 29 and the driven bevel gear 21, the driven bevel gear 21 will... The rotating shaft 28 is driven to rotate, and the driving pulley 13 on the surface of the rotating shaft 28 will rotate together. Then, under the belt drive of the transmission belt 14, multiple driven pulleys 15 will drive multiple connecting seats 16 and steel brush heads 12 to rotate, thereby achieving the effect of multiple steel brush heads 12 rotating simultaneously. Several mounting seats 18 are fixedly installed on the top surface of the positioning frame 10. A connecting rod 25 is movably sleeved inside the mounting seat 18. A second spring 24 is fixedly sleeved on the outer circular wall of the connecting rod 25. A mounting rod 26 is fixedly installed at one end of the connecting rod 25. A pressure roller 27 is rotatably connected to one end of the mounting rod 26. When the transmission belt 14 rotates, the second spring 24 inside the mounting seat 18 will provide a rebound force to make the mounting rod 26 drive the pressure roller 27 to move, and keep the pressure roller 27 always in contact with the surface of the transmission belt 14, thereby facilitating the limiting of the transmission belt 14 and preventing the transmission belt 14 from falling off.

[0032] Based on the above embodiments, refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 Two clamping plates 23 are fixedly installed on the bottom surface of the steel brush head 12, and two limiting plates 22 are fixedly installed on the top surface of the connecting seat 16. The clamping plates 23 and the limiting plates 22 are slidably connected to each other to limit the up and down movement of the steel brush head 12. Protective covers 17 are fixedly sleeved on the outer circular wall surface of several steel brush heads 12 to prevent falling aluminum dust from entering the interior of the connecting seat 16 and affecting its use. A guide cover 9 is fixedly installed inside the frame 1. Several circular through holes are opened on the top surface of the guide cover 9. The inner circular wall surface of the circular through holes is movably sleeved with the protective cover 17 to facilitate the guidance and discharge of falling aluminum dust, and at the same time prevent falling aluminum dust from entering between the drive pulley 13, the transmission belt 14 and the driven pulley 15 and affecting its use. A dust cover 3 is rotatably connected to the top surface of the frame 1 to prevent dust from being generated during grinding.

[0033] Working principle: Please refer to Figures 1-7 As shown, during use, the operator places the aluminum ash block to be ground along with the grinding balls inside the grinding cylinder 5. The operator then uses the first motor 6, and the drive shaft of the first motor 6 rotates, which in turn drives the shaft of the steering gear 7 to rotate. At this time, under the action of belt drive, the grinding cylinder 5 will rotate accordingly. The grinding balls inside the grinding cylinder 5 will roll and continuously impact the aluminum ash block, breaking it into smaller pieces, thereby achieving the effect of ball grinding the aluminum ash block. When the grinding cylinder 5 rotates, the operator uses the drive assembly to rotate multiple steel brush heads 12. The first spring 19 inside the connecting seat 16 will provide an upward elastic force, causing the steel brush heads 12 to continuously contact the surface of the grinding cylinder 5. Then, the steel brushes on the surface of the steel brush heads 12 will enter the interior of the feeding holes on the surface of the grinding cylinder 5, thereby clearing the blockage of aluminum ash inside. After grinding, the aluminum ash will fall into the interior of the collection tray 8 through the holes on the surface of the grinding cylinder 5. This achieves the effect of facilitating ball grinding of aluminum ash and preventing blockage during aluminum ash feeding.
