Aluminum alloy scrap pretreatment is a series of processes that make the recycled aluminum alloy scrap suitable for recycling.

[0003] Pre-treatment of aluminum alloy waste typically includes processes such as sorting, dismantling, cutting, and crushing. When crushing aluminum alloy waste, traditional crushing devices are prone to being jammed by large or hard aluminum alloy waste during operation, which can easily cause the transmission mechanism of the crushing device to break. Furthermore, the high current passing through the motor for a long time can also be dangerous. In addition, traditional aluminum alloy waste crushing devices have a large workload, and the motor is prone to heat accumulation during long-term operation, requiring timely heat dissipation. Therefore, a crushing device for pre-treatment of aluminum alloy waste is proposed. Summary of the Invention

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4This utility model provides a technical solution: a crushing device for pre-processing aluminum alloy waste, including an automatic separation device 1, a cooling device 2, and a crusher shell 3. The automatic separation device 1 includes a first separation mechanism 101, a tension rod 102, a second separation mechanism 103, a compression spring 104, a limiting block 105, an inner rod 106, and an outer rod 107. One end of the tension rod 102 is fixedly connected to the central position inside the first separation mechanism 101, and the other end of the tension rod 102 is fixedly connected to the limiting block 105. The surface of the tension rod 102 is slidably and rotatably connected to the interior of the second separation mechanism 103 and the inner rod 106. One end of the inner rod 106 is connected to the second separation mechanism 107. The outer side of 103 is fixedly connected, and the compression spring 104 is located between the limiting block 105 and the inner side of the inner rod 106. The surface of the inner rod 106 is slidably connected to the inside of the outer rod 107. By setting the first separation mechanism 101, the second separation mechanism 103, and the compression spring 104, the elastic characteristics of the compression spring 104 make the first separation mechanism 101 and the second separation mechanism 103 fit tightly when the aluminum alloy waste crushing device is working normally. When the aluminum alloy waste crushing device is jammed, the first separation mechanism 101 and the second separation mechanism 103 separate, ensuring that the power motor 13 can continue to work when the crushing device cannot work, thus improving the safety of the device.

[0026] The cooling device 2 includes a semi-circular heat dissipation pipe 201, a connecting pipe 202, and a cooling fan 203. The air inlet of the semi-circular heat dissipation pipe 201 is connected to one end of the connecting pipe 202, and the other end of the connecting pipe 202 is connected to the air outlet of the cooling fan 203. Multiple annular channels 2011 are evenly opened inside the semi-circular heat dissipation pipe 201. By setting up the semi-circular heat dissipation pipe 201, the connecting pipe 202, and the cooling fan 203, and by starting the cooling fan 203, external cold air carries away the heat inside the semi-circular heat dissipation pipe 201, thereby cooling the power motor 13, improving the working efficiency of the device, and further extending the service life of the device.

[0027] The air inlet of the cooling fan 203 is equipped with a dustproof net 2031. By setting the dustproof net 2031, dust can be effectively prevented from entering the interior of the cooling device 2 when the cooling fan 203 is working, thus avoiding clogging of the cooling device 2 and affecting its cooling effect.

[0028] Two first bearings 4 are fixedly installed at the same horizontal height on both sides of the crusher housing 3. A crushing mechanism 5 is installed between the two pairs of first bearings 4. The inner rings of the two first bearings 4 on one side are rotatably connected to a large gear 6. A second bearing 7 is installed inside one side of the crusher housing 3. The inner ring of the second bearing 7 is rotatably connected to a small gear 8. A connecting rod 10 is fixedly connected between the outer side of the first separation mechanism 101 and the small gear 8. The surfaces of the two large gears 6 are meshed with each other. The surface of one of the large gears 6 is meshed with the small gear 8. A slope 9 is provided at the bottom inside the crusher housing 3. A base plate 11 is fixedly connected to the bottom of one side of the crusher housing 3. A mounting bracket 12 is fixedly connected to the upper end of the base plate 11. A power motor 13 is installed at the upper end of the mounting bracket 12. The outer surface of the power motor 13 is attached to the semi-circular heat dissipation pipe 201. The output shaft of the power motor 13 is fixedly connected to the outer rod 107. The slope 9 facilitates the aluminum alloy waste after being crushed by the aluminum alloy waste crushing device to slide out from the discharge port.

[0029] The semi-circular heat sink 201 is made of thermally conductive copper. The elastic force generated by the compression of the compression spring 104 to a certain degree can ensure that the first separation mechanism 101 and the second separation mechanism 103 will not separate when the device is working normally. When stuck, the first separation mechanism 101 and the second separation mechanism 103 will separate. The use of thermally conductive copper material improves the heat exchange between the semi-circular heat sink 201 and the surface of the power motor 13.

[0030] Working principle: When in use, the power is turned on. To avoid the crushing device from getting stuck and causing danger, when the aluminum alloy waste crushing device is working normally, due to the pressure of the compression spring 104, the first separation mechanism 101 and the second separation mechanism 103 are tightly fitted together. The power motor 13 drives the pinion 8 to rotate through the automatic separation device 1 and the connecting rod 10. The surface of the pinion 8 drives the large gear 6 to rotate, so that the crushing mechanism 5 works and realizes the crushing of aluminum alloy waste. When the aluminum alloy waste crushing device is momentarily stuck by aluminum alloy waste, the first separation mechanism 101 immediately stops rotating, while the second separation mechanism 103, under the operation of the power motor 13, overcomes the pressure generated by the compression spring 104 and separates from the first separation mechanism 101 and continues to rotate, thereby avoiding the crushing device from getting stuck and causing danger.

[0031] When cooling the motor, the cooling fan 203 is started to draw external cold air into the interior of the annular channel 2011 through the connecting pipe 202. The surface of the power motor 13 exchanges heat with the semi-circular heat dissipation pipe 201, which causes the surface temperature of the power motor 13 to drop, thus achieving heat dissipation of the motor.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
