[0002] As an important lightweight metal material, aluminum is used in various profiles, plates and products with excellent properties such as light weight, high strength, corrosion resistance, good electrical and thermal conductivity and easy recyclability through plastic processing and modification technologies such as smelting, casting, rolling and heat treatment. These materials are widely used in construction, transportation, packaging and aerospace fields. Its recyclable characteristics also constitute a key part of modern green metallurgy technology.

[0003] Aluminum scraps tend to clump together when piled up and subjected to pressure during transport. Directly melting these clumps can cause uneven heating and rapid vaporization of moisture, leading to molten metal splashing or even explosions, posing serious safety hazards. Furthermore, the outer layer of the clump is already melted and oxidized while the inside remains solid, significantly reducing thermal efficiency, prolonging melting time, and generating more oxide slag. This results in a significant decrease in aluminum recovery rate and an increase in energy costs. Therefore, this paper proposes an aluminum scrap recycling, conveying, and melting pool to address these issues. Summary of the Invention

[0004] To address the shortcomings of existing technologies, which pose serious safety hazards and increase energy costs due to the direct melting of aluminum shavings into clumps, this invention proposes an aluminum shavings recycling and conveying melting pool.

[0016] 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 scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. This application discloses an aluminum scrap recycling and conveying melting pool. (Refer to...) Figure 1 and Figure 2A melting pool for recycling aluminum scrap includes a body 1. A rotating shaft 101 is rotatably connected inside the body 1, with both ends of the shaft 101 penetrating the body 1 and rotatably connected to its inner cavity. A conveyor belt 102 is mounted on the surface of the shaft 101. A melting pool body 103 is located at the bottom of the body 1, and the conveyor belt 102 works in conjunction with the melting pool body 103. A vibration mechanism 2 is located at the top of the body 1, and works in conjunction with the conveyor belt 102. The melting pool body 103 includes a gas burner or electric heating element, an aluminum outlet, a drain outlet, and a heat exchange system for recovering waste heat from exhaust gas, etc., which are existing technologies and will not be elaborated further here. The vibration mechanism 2 includes two fixed frames 201 fixedly connected to the top sides of the machine body 1. A slider 202 is slidably connected inside the fixed frame 201. A first spring 203 is fixedly connected inside each of the two fixed frames 201. One end of each of the two first springs 203 is fixedly connected to the bottom of the two sliders 202 respectively. A rotating rod 204 is rotatably connected to the opposite side of the two sliders 202. An eccentric block 205 is fixedly connected to the surface of the rotating rod 204. A drum screen 206 is fixedly sleeved on the surface of the rotating rod 204. A hopper 207 is fixedly connected to the top of one of the fixed frames 201. The hopper 207 works in conjunction with the drum screen 206. A cleaning assembly 3 is provided on the top of the machine body 1. The cleaning assembly 3 works in conjunction with the drum screen 206. A transmission assembly 4 is provided at one end of the rotating shaft 101. The transmission assembly 4 works in conjunction with the rotating rod 204. When aluminum shavings need to be melted, the aluminum shavings are conveyed through the hopper 207 to the inside of the drum screen 206. Then, the transmission assembly 4 drives the rotating rod 204 to rotate the drum screen 206. The centrifugal force generated by the eccentric block 205 causes the rotating rod 204 to drive the slider 202 to slide in the inner cavity of the fixed frame 201. When the slider 202 slides, the first spring 203 limits the sliding distance of the slider 202 and causes the slider 202 to slide back and forth at a high frequency. This causes the rotating rod 204 to drive the drum screen 206 to generate high-frequency vibration. The vibration disperses the clumps of aluminum shavings. Combined with the centrifugal force generated by the rotation of the drum screen 206, the clumps of aluminum shavings are broken up and the loose aluminum shavings are thrown onto the surface of the conveyor belt 102. The conveyor belt 102 can then transport the loose aluminum shavings to the inside of the melting pool body 103 for melting.

[0018] Reference Figure 1 and Figure 4The cleaning assembly 3 includes a bracket 301 fixedly connected to the top of the machine body 1. A reciprocating screw 302 is rotatably connected inside the bracket 301. A moving block 303 is threadedly connected to the surface of the reciprocating screw 302. A brush 304 is fixedly connected to the surface of the moving block 303. The surface of the brush 304 is in contact with the surface of the drum screen 206. One end of the reciprocating screw 302 is used in conjunction with the transmission assembly 4. A limit groove 305 is formed inside the bracket 301, and a limit block is fixedly connected to the top of the moving block 303. 306, the surface of the limiting block 306 is slidably connected to the inner cavity of the limiting groove 305; while the drum screen 206 vibrates the aluminum chips, the transmission component 4 drives the reciprocating screw 302 to rotate, and through the stabilization of the limiting block 306 and the limiting groove 305, the reciprocating screw 302 can drive the moving block 303 to slide in the inner cavity of the bracket 301, so that the moving block 303 can drive the brush 304 to brush off the aluminum chips attached to the surface of the drum screen 206, thereby improving resource utilization and avoiding waste.

[0019] Reference Figure 1 and Figure 2 The transmission assembly 4 includes a motor 401 fixedly installed on one side of the machine body 1. The output end of the motor 401 is fixedly connected to one end of the rotating shaft 101. A first gear 402 is fixedly sleeved on one end of the rotating shaft 101. One end of the rotating rod 204 passes through another fixed frame 201 and is rotatably connected to the inner cavity of the other fixed frame 201. A second gear 403 is fixedly sleeved on one end of the rotating rod 204. The surfaces of the first gear 402 and the second gear 403 are jointly driven by a first synchronous toothed belt 404. When the drum screen 206 needs to be used, the motor 401 is started. The motor 401 drives the first gear 402 to rotate through the rotating shaft 101. The first gear 402 drives the second gear 403 to rotate through the first synchronous toothed belt 404. The second gear 403 drives the drum screen 206 to rotate and vibrate through the rotating rod 204, thereby breaking up the clumps of aluminum chips.

[0020] Reference Figure 2 and Figure 3 A connecting frame 405 is fixedly connected to one side of the machine body 1. A connecting block 406 is slidably connected inside the connecting frame 405. A tension wheel 407 is fixedly connected to the surface of the connecting block 406. The tension wheel 407 works in conjunction with the first synchronous toothed belt 404. A second spring 408 is provided inside the connecting frame 405. One end of the second spring 408 is fixedly connected to the inner wall of the connecting frame 405, and the other end of the second spring 408 is fixedly connected to the bottom of the connecting block 406. When the drum screen 206 vibrates up and down, the tension wheel 407 is tightly engaged with the first synchronous toothed belt 404 by the push of the second spring 408, thereby ensuring the number of teeth engaged between the first synchronous toothed belt 404 and the first gear 402 and the second gear 403, and preventing the first synchronous toothed belt 404 from becoming loose.

[0021] Reference Figure 1 and Figure 4 The other end of the rotating shaft 101 is fixedly fitted with a third gear 409. One end of the reciprocating screw 302 passes through the bracket 301 and is rotatably connected to the inner cavity of the bracket 301. One end of the reciprocating screw 302 is fixedly fitted with a fourth gear 410. The surface of the third gear 409 and the surface of the fourth gear 410 are jointly fitted with a second synchronous toothed belt 411. While the drum screen 206 rotates, the rotating shaft 101 drives the third gear 409 to rotate. The third gear 409 causes the fourth gear 410 to rotate through the second synchronous toothed belt 411, so that the fourth gear 410 can drive the reciprocating screw 302 to rotate. Thus, the reciprocating screw 302 drives the brush 304 to clean the surface of the drum screen 206 through the moving block 303.

[0022] Working principle: When aluminum shavings need to be melted, the shavings are fed into the drum screen 206 through the hopper 207. Then, the motor 401 is started, which drives the conveyor belt 102 to rotate via the shaft 101. Simultaneously, the shaft 101 drives the first gear 402 to rotate. The first gear 402, through the first synchronous toothed belt 404, drives the second gear 403 to rotate, which in turn drives the rotating rod 204 to rotate. Stable by the eccentric block 205, the rotating rod 204 drives the drum screen 206 to rotate and vibrate, thereby breaking up clumps of aluminum shavings. The centrifugal force generated by the rotating screen then throws the shavings onto the surface of the conveyor belt 102. The conveyor belt 102 transports loose aluminum shavings to the interior of the melting pool body 103 for smelting, thereby improving the thermal efficiency of the furnace and reducing slag formation and aluminum oxidation loss. While the drum screen 206 rotates, the rotating shaft 101 drives the third gear 409 to rotate. The third gear 409 drives the fourth gear 410 to rotate through the second synchronous toothed belt 411. The fourth gear 410 drives the reciprocating screw 302 to rotate. The reciprocating screw 302 drives the brush 304 to move back and forth in the inner cavity of the support 301 through the moving block 303, so that the brush 304 can sweep off the aluminum shavings attached to the surface of the drum screen 206, thereby improving resource utilization and avoiding waste.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
