Description

Technical Field

[0002] In the aluminum processing industry, aluminum waste slag is the main waste in the production process. Its output is increasing with the growth of demand for aluminum products. Aluminum waste slag contains a large amount of recyclable aluminum elements. If it cannot be effectively treated and reused, it will not only cause serious waste of resources, but also have many negative impacts on the environment. With the increasingly severe problem of resource shortage and the continuous improvement of environmental protection requirements, the reuse of aluminum waste slag has gradually received attention;

[0003] Although the existing aluminum waste slag recycling and processing devices in life have met the needs of users to a certain extent, there are still certain defects in the use process. The specific problems are as follows: the existing aluminum waste slag recycling and processing technology cannot achieve crushing and grading of aluminum waste slag, which leads to uneven particle size of aluminum waste slag raw materials entering the subsequent smelting process. Since particles of different particle sizes require different amounts of heat and time during the heating process, during the smelting process, smaller particles may melt quickly, while larger particles require longer time and higher temperatures to reach the melting point, which can easily cause local overheating, which not only wastes a lot of energy, but also may cause some aluminum elements to be oxidized due to excessive heating, reduce the purity of recycled aluminum, and even cause incomplete melting, seriously affecting the quality and output of recycled aluminum;

[0046] Working principle: When the aluminum waste slag needs to be recycled, the aluminum waste slag to be processed is put into the crushing box 21, and the driving motor 25 is started to drive the rotating shaft 22 connected thereto to rotate. Since the driving gears 24 at one end of the two sets of rotating shafts 22 are meshed with each other, the other set of rotating shafts 22 will also rotate synchronously. The crushing rollers 23 on the two sets of rotating shafts 22 are staggered and meshed to squeeze and crush the aluminum waste slag put into the crushing box 21, which can quickly and effectively reduce the volume of the waste slag. During this period, the rotation of the rotating shaft 22 is controlled by the bevel gear pair 28. The transmission shaft 29 transmits the transmission to the bevel gear pair 210, thereby driving the driving shaft 211 to rotate, the driving gear 212 on the driving shaft 211 meshes with the driven gear 213, so that the driven shaft 214 rotates, and the eccentric rods 215 at both ends of the driven shaft 214 drive the push-pull block 218 to make reciprocating linear motion in the push-pull seat 219 through the hinge rod 216 and the push-pull rod 217, so that the connecting frame 220 drives the screening net 221 to make high-frequency reciprocating motion on the positioning pulley 222, and the particles smaller than the aperture of the screening net 221 pass through the screen and fall into the gathering hopper 26 for collection, while the larger particles are collected. The particles remain on the screen mesh 221, which can accurately classify the aluminum waste slag according to the particle size, ensuring that only the waste slag particles that meet the specific particle size requirements pass through the screening mesh 221 and are collected in the gathering hopper 26, while the larger particles remain on the screening mesh 221 waiting for further crushing processing, which greatly improves the processing efficiency, avoids excessive crushing or insufficient crushing, ensures that the particle size of the materials entering the subsequent process is uniform and meets the process requirements for reuse, and provides a high-quality raw material basis for subsequent smelting, refining and other processes, which helps to improve the production efficiency and product quality of the entire aluminum waste slag recycling production line, and optimizes the processing workflow of aluminum waste slag, and can screen and separate the waste slag in real time during the crushing process, avoiding the tedious process of mixing all the crushed materials together and then conducting a secondary screening. The operator does not need to transfer the crushed material to other equipment for screening, which reduces the material transfer link, reduces the labor intensity and labor cost, greatly improves the processing efficiency, reduces the ineffective operation time of the equipment, accelerates the conversion speed of aluminum waste slag from the original state to the reusable state, and improves the overall production capacity of the production line.

[0047] It is worth noting that the aluminum waste slag particles after crushing are smaller and more uniform, and their physical properties are improved, which makes the subsequent smelting, purification and other further processing steps can be carried out more smoothly. During the smelting process, smaller particles can reach the melting point faster, which improves the smelting speed and efficiency. It is also beneficial to the uniform transfer of heat, reduces energy waste and quality fluctuations during the smelting process, improves the stability of product quality, and promotes the efficient recycling of resources. The positioning pulley 222 can effectively guide the movement trajectory of the screening net 221, reduces the shaking and deviation of the screening net 221 during movement, reduces the incidence of equipment failures, and extends the service life of the equipment.

[0048] Furthermore, as the rotating shaft 22 rotates, the reciprocating screw rod 310 is driven to rotate through the transmission chain 39, so that the reciprocating thread block 311 makes a reciprocating motion on the reciprocating screw rod 310, thereby driving the push plate 312 to slide in the moving groove in the crushing box 21, so that the large particles of aluminum waste slag retained on the screening net 221 can be pushed to the discharge hopper 223, and finally fall into the receiving hopper 32, so that the accumulated large particles of waste slag are pushed away in time, the screening net 221 is kept unobstructed, and the aluminum waste slag is prevented from accumulating on the screening net 221 and clogging the mesh of the screening net, thereby ensuring crushing and The screening work can be carried out continuously and stably, and it is ensured that all the aluminum waste slag can be fully crushed until it reaches the usable particle size standard, which greatly improves the resource recovery rate of the aluminum waste slag and reduces the resource waste caused by incomplete material processing. During this period, as the transmission shaft 29 rotates, the transmission gear 2 36 connected thereto can be driven to rotate, and the transmission gear 2 36 is meshed with the transmission gear 1 35, so that one group of spiral augers 34 rotates. Through the connection of the synchronous chain 38, the two groups of spiral augers 34 rotate synchronously, and the material from the receiving hopper can be The waste slag entering the conveying cylinder 31 is transported upward and then discharged from the discharging hopper 33. The discharged aluminum waste slag will fall into the lower hopper 323. At this time, through the rotation of the rotating shaft 22, under the action of the bevel gear pair 313, the rotating shaft 314, the transmission chain 215 and the transmission rod 316, the cam 319 can be driven to rotate. Then the cam 319 periodically pushes the push rod 320 to overcome the elastic force of the spring 321 to slide inside the blocking plate 318, thereby driving the blocking plate 322 to slide synchronously inside the lower hopper 323, that is, The discharging timing and flow rate of aluminum waste slag from the discharge hopper 323 into the crushing box 21 can be controlled to achieve intermittent and accurate discharging of materials, avoiding the problem of insufficient crushing due to too fast discharge, or too slow discharge affecting the overall processing efficiency, ensuring that the crushing roller 23 is always in the best working state, enabling the crushing roller 23 to effectively crush the incoming waste slag, improving the uniformity and quality of the crushing, and ensuring that the waste slag particles finally output meet the particle size requirements of subsequent processes, providing a high-quality and stable raw material basis for subsequent smelting and other recycling links.

[0049] It is worth noting that reasonable material flow can allow the crushing equipment to operate under appropriate load, avoiding excessive energy consumption due to equipment overload caused by too much material, or energy waste such as equipment idling due to too little material, improving the energy utilization efficiency of the entire processing device, meeting the production requirements of energy conservation and emission reduction, reducing the company's production costs, and improving economic benefits. There is no need for frequent manual intervention to adjust the material transportation and discharge, which greatly reduces the labor intensity of operators and enables them to devote more energy to monitoring the overall operating status of the equipment and other production management work, thereby improving work efficiency and the refinement of production management.

[0050] Furthermore, the aluminum waste slag after crushing and screening falls into the crucible 411 through the feeding hole of the collecting hopper 26 and the furnace cover 414, and the electric heating block 412 is energized to generate heat, and the aluminum waste slag in the crucible 411 is melted at high temperature to convert the aluminum waste slag into liquid aluminum. When the liquid aluminum needs to be dumped, the dumping motor 43 is started to drive the dumping gear 44 to rotate, thereby driving the dumping gear ring 45 to rotate. Since the dumping gear ring 45 is fixedly connected to the flip plate 47, and the flip plate 47 realizes stable rotation through the cooperation of the limit ring 46 and the limit wheel 48, under the centering effect of the centering shaft 49, The flip plate 47 can only rotate around the centering shaft 49 to achieve a slow dumping action of the smelting furnace 410, so that the angle and position of each dumping can be accurately controlled, effectively avoiding the splashing of molten aluminum caused by rapid dumping, not only reducing the spillage and waste of molten aluminum, improving the yield and material utilization rate of the production process, but also reducing the risk of operators being scalded by high-temperature molten aluminum, providing a safe and reliable operating environment for the staff, reducing the probability of safety accidents, and the generated molten aluminum can be poured out through the dumping nozzle 413 for subsequent processing to achieve the recycling of aluminum waste.

[0051] The flip plate 47 achieves stable rotation through the cooperation of the limiting ring 46 and the limiting wheel 48, as well as the centering effect of the centering shaft 49. This mechanical structure design ensures the stability and safety of the smelting furnace 410 during the dumping process, and effectively prevents the occurrence of dangerous situations such as aluminum liquid leakage and splashing caused by furnace shaking, deviation or loss of control. Even during frequent dumping operations and long-term use, it can maintain good stability and reliability.

[0052] It is worth noting that the feed hole on the furnace cover 414 is used to receive the waste slag dropped from the collecting hopper 26. During the smelting process, the furnace cover 414 plays a role in reducing heat loss and preventing impurities from entering, thereby ensuring the efficiency and purity of the smelting process. The multiple groups of electric heating blocks 412 arranged in a ring ensure that the waste slag in various parts of the crucible 411 can be heated evenly, avoiding the problem of uneven smelting caused by local overheating or overcooling, further improving the smelting effect and product quality, and significantly improving the recycling rate of aluminum waste slag.
