Description

Technical Field

[0001] This invention relates to the field of waste aluminum recycling technology, specifically to a waste aluminum product recycling device. Background Technology

[0002] Aluminum is the most widely used non-ferrous metal, with advantages such as light weight, high durability and recyclability. Moreover, the aluminum industry is a high-energy-consuming industry, so the recycling and reuse of waste aluminum is particularly important.

[0003] Existing aluminum scrap recycling methods typically utilize permanent magnet stirrers, electromagnetic stirrers, electromagnetic pumps, mechanical pumps, or other devices to create a vortex in the molten aluminum at the aluminum scrap feeding port of the aluminum melting furnace. The aluminum scrap is then fed into the vortex and melted and carried away. However, because the aluminum scrap initially floats on the surface of the molten aluminum, it burns rapidly upon contact with the high-temperature molten aluminum, increasing the loss of aluminum scrap and reducing the actual recovery rate.

[0004] To this end, patent CN101235443A discloses a waste aluminum recycling system. This invention features a feeding pipe at the feeding point of the smelting furnace, with its lower end inserted into the molten aluminum. The upper end of the feeding pipe has a feeding port, and a mechanically driven longitudinal feeding component is installed inside the pipe. When aluminum scraps are fed in through the feeding port, the longitudinal feeding component pushes the scraps downwards through the feeding pipe, squeezing them out from the bottom and carrying them away with the flowing molten aluminum. This allows the aluminum scraps to melt without contacting air. Therefore, this invention almost eliminates combustion during aluminum scrap melting, improving the smelting yield. Furthermore, since the aluminum scraps are directly pressed into the molten aluminum layer, there is no need to form vortices to cause the molten aluminum to churn, eliminating the need for vortex-generating mechanical devices. Therefore, this invention has a relatively simple structure and is easy to install and maintain. Because no vortexes are formed to cause the molten aluminum to churn, the oxide film on the surface of the molten aluminum is not damaged, thus preventing the formation of new alumina and greatly reducing the oxidation loss of the molten aluminum.

[0005] However, the above equipment still has defects: 1. The lower end of the conveying pipe is directly inserted into the center of the vortex of the aluminum liquid. The scrap aluminum pressed in from above enters the aluminum liquid from the lower end of the conveying pipe, resulting in a single discharge position. At the discharge position, there is a lot of scrap aluminum. The scrap aluminum cannot reach the interior of the aluminum liquid in a vertical height, which reduces the melting efficiency; 2. When the conveying pipe conveys scrap aluminum downward, the outside air is also conveyed downward, so that the gas enters the interior of the aluminum liquid, causing bubbles to be generated inside the aluminum liquid, which affects the effect of the aluminum forming parts in the later stage. Summary of the Invention

[0006] The purpose of this invention is to provide a waste aluminum product recycling device to solve the problems of uneven melting and bubble generation in molten aluminum mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a waste aluminum product recycling device, comprising a melting furnace and an electromagnetic stirrer disposed below the melting furnace, wherein a frustum-shaped outer shell is inserted from above into the middle of the melting furnace, a conical auger body is disposed inside the frustum-shaped outer shell, and a hollow cylinder is installed below the frustum-shaped outer shell.

[0008] The portion of the frustum-shaped outer shell inside the melting furnace has densely packed exhaust holes. A buffer chamber is inserted above the melting furnace. The buffer chamber is located outside the frustum-shaped outer shell, and at least three heat recovery pipes are evenly installed between the buffer chamber and the feed hopper.

[0009] Furthermore, an integral conical hopper is provided below the feed hopper, the lower end of which is fixedly connected to the upper end of the frustum-shaped outer shell. The feed hopper is provided with staggered baffles, and the baffles are provided with dense through holes. The end of the heat recovery pipe inserted into the feed hopper is equipped with an upward-curving part.

[0010] Furthermore, the baffle plate has an installation groove on the side near the inner wall of the feed hopper, a pin is fixed inside the installation groove, and a mounting seat is fixed on the inner wall of the feed hopper at a position corresponding to the installation groove. A torsion spring is provided between the pin and the mounting seat.

[0011] Furthermore, the hollow cylinder includes two parallel rings arranged side by side, with a gap between two adjacent rings. At least two connecting columns are fixed between two adjacent rings, and a downwardly inclined guide plate is installed on the outer side of the ring. The upper surface of the guide plate is open at the top, and the lower surface of the guide plate is open at the bottom.

[0012] Furthermore, an auger drive structure capable of driving the conical auger body to rotate is provided above the buffer air chamber. The auger drive structure includes a first motor installed on the upper surface of the buffer air chamber, a pulley fixed at the power output end of the first motor and the upper end of the conical auger body, and a belt for driving the two pulleys.

[0013] Furthermore, a fixed ring is fixed to the outer circumference of the frustum-shaped outer shell located above the interior of the buffer chamber. A rotating ring is rotatably mounted on the outside of the fixed ring via a bearing. A guide fan is fixed above the outer surface of the rotating ring. A guide fan drive structure capable of driving the rotating ring is provided on one side of the interior of the buffer chamber.

[0014] Furthermore, the guide fan drive structure includes a second motor installed on one side inside the buffer chamber, a drive gear fixed to the power output end of the second motor, and a driven gear fixed below the rotating ring, wherein the drive gear meshes with the driven gear.

[0015] Furthermore, it also includes a base, on which the electromagnetic stirrer is mounted.

[0016] Furthermore, a discharge pipe is provided on one side of the lower part of the melting furnace, and a shut-off valve is provided on the discharge pipe.

[0017] Furthermore, the melting furnace is provided with an inner liner, and a combustion chamber is provided between the inner liner and the melting furnace.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The present invention divides the original integral feeding cylinder into a frustum-shaped outer shell and a hollow cylinder. Then, as the scrap aluminum moves downward to the inside of the hollow cylinder, it continues to move downward. During its continued downward movement, part of the scrap aluminum is carried away by the vortex, while the other part continues to move downward until it reaches the bottom ring for discharge. This allows the scrap aluminum to reach the interior of the molten aluminum evenly in the height direction, ensuring the uniformity of its melting.

[0020] 2. The present invention is equipped with a guide plate, so that the scrap aluminum carried by the eddy current can move along the guide plate, further ensuring that the scrap aluminum can reach the interior of the molten aluminum uniformly in the height direction.

[0021] 3. The present invention has an exhaust hole on the lower side wall of the frustum-shaped outer shell and a buffer gas chamber inserted above the melting furnace. The gas pressed down by the conical auger body can reach the interior of the buffer gas chamber through the exhaust hole, thus avoiding the gas from reaching the interior of the aluminum liquid and causing bubbles to be present inside the aluminum liquid.

[0022] 4. In this invention, a heat recovery pipe is set between the buffer gas chamber and the feed hopper. Because the temperature inside the buffer gas chamber is high, the gas is in a heated state, making it a hot air flow. The hot air flow can reach the inside of the feed hopper through the heat recovery pipe to preheat the initial scrap aluminum, thereby promoting the melting operation of the scrap aluminum after entering the inner liner.

[0023] 5. The present invention is equipped with a flow guide fan, which can quickly transport the gas discharged from the exhaust port to the interior of the heat recovery pipe to avoid the accumulation of hot gas.

[0024] 6. The present invention installs a vibrating baffle inside the feed hopper, thereby extending the preheating time of waste aluminum. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figure 1 and Figure 2 As shown, the present invention provides a technical solution for a waste aluminum product recycling device: A waste aluminum product recycling device includes a melting furnace 3, an inner liner 23 inside the melting furnace 3, and a combustion chamber 24 between the inner liner 23 and the melting furnace 3. Combustion gas, such as natural gas, can be introduced into the combustion chamber 24. It is necessary to open holes in the melting furnace 3 and install natural gas delivery pipes at the hole locations to facilitate the delivery of natural gas into the combustion chamber 24. It is also necessary to equip the combustion chamber 24 with an ignition structure to ignite the natural gas (the ignition technology of natural gas is very mature and will not be elaborated further here. It should be noted that the melting furnace has air circulation holes). The heat generated after the natural gas combustion can reach the waste aluminum through the inner liner 23, causing the waste aluminum to melt at high temperature. A discharge pipe 4 is provided on one side of the melting furnace 3, and a shut-off valve is provided on the discharge pipe 4. The shut-off valve closes the discharge pipe 4. When discharge is required, it can be achieved by opening the shut-off valve.

[0039] like Figure 1 and Figure 2 As shown, a base 1 is provided below the melting furnace 3, and an electromagnetic stirrer 2 is provided between the base 1 and the melting furnace 3. When the electromagnetic stirrer 2 is working, it can generate a vortex in the aluminum liquid inside the inner liner 23. When aluminum chips reach the center of the aluminum liquid vortex, they can be carried away by the aluminum liquid.

[0040] Combination Figure 2 and Figure 6 As shown, in order to ensure that the scrap aluminum can accurately reach the center of the molten aluminum vortex and to prevent the scrap aluminum from floating on the surface of the molten aluminum, a frustum-shaped outer shell 9 is inserted from the middle of the furnace 3. The interior of this frustum-shaped outer shell 9 is equipped with a conical auger body 10. As the conical auger body 10 rotates, it can gradually convey the scrap aluminum downwards. Since the diameters of the conical auger body 10 and the frustum-shaped outer shell 9 gradually decrease, the scrap aluminum can also be slightly compressed during its downward movement to increase the density (weight) of the compressed scrap pieces, thereby allowing the molten aluminum to carry the scrap pieces away more quickly.

[0041] like Figure 4In order to achieve the rotation of the conical auger body 10, an auger drive structure 11 capable of driving the conical auger body 10 to rotate is provided above the buffer air chamber 5. Further, in this embodiment, the auger drive structure 11 includes a first motor 111 installed on the upper surface of the buffer air chamber 5, a pulley 112 fixed at the power output end of the first motor 111 and the upper end of the conical auger body 10, and a belt 113 for driving the two pulleys 112. That is, the pulley 112 on the first motor 111 is rotated by the power driving action of the first motor 111, and the conical auger body 10 is rotated by the pulley 112 and the belt 113 at the upper end of the conical auger body 10, so that it can push the waste aluminum downward.

[0042] Combination Figure 4 , Figure 5 and Figure 6 As shown, to further prevent the waste aluminum from floating on the molten aluminum and causing burn damage, and to ensure that the waste aluminum reaches the vertical vortex center evenly in the vertical direction, the lower end of the conical auger body 10 is extended downwards, and parallel rings 17 are installed below the frustum-shaped outer shell 9. At least two connecting columns 18 are fixed between two adjacent rings 17, thereby using the connecting columns 18 to make the two adjacent rings 17 merge into one, and a gap is provided between the two adjacent rings 17 (parallel rings 17, connecting columns). 18 and the gap, together forming a hollow cylinder), and then after the scrap aluminum flows downward and exits from the lower end of the frustum-shaped outer shell 9, it will reach the interior of this hollow cylinder and continue to move downward, causing it to continue to move downward in the center of the vortex. During its continued downward movement, some of the scrap aluminum is carried away by the vortex (at this time, this scrap aluminum can pass through the gap and enter the interior of the molten aluminum for melting), while the other part of the scrap aluminum continues to move downward until it reaches the bottom of the lowest ring 17 for exit, thus completing the entire process of the scrap aluminum being drawn into the interior of the molten aluminum.

[0043] Reference Figure 3 , Figure 7 and Figure 8 As shown, further, in order to ensure that the scrap aluminum carried away by each vortex from the gap between the two rings 17 can melt at the initial height of being carried away (this is to ensure that the scrap aluminum can be melted at each height of the aluminum liquid, so that the melting is uniform), a downwardly inclined guide plate 8 is installed on the outer side of the ring 17, so that the scrap aluminum carried away by the vortex can move along the guide plate 8 to ensure uniform melting. The upper surface of the guide plate 8 is set as an upper opening 81, and the lower surface of the guide plate 8 is set as a lower opening 82.

[0044] Combination Figure 1 , Figure 2 and Figure 3As shown, in actual operation, during the downward conveying of scrap aluminum by the conical auger body 10, external gas is forced into the interior of the scrap aluminum, resulting in a large number of air bubbles inside the molten aluminum, which affects the subsequent forming of the molten aluminum. Therefore, dense exhaust holes 13 are provided in the part of the frustum-shaped outer shell 9 located inside the melting furnace 3. Thus, during the downward compression and conveying of scrap aluminum by the conical auger body 10, a large amount of gas conveyed downward can be discharged outward through the exhaust holes 13. In order to discharge the gas discharged from the exhaust holes 13 out of the melting furnace 3, a buffer is inserted above the melting furnace 3. The buffer chamber 5 is located outside the frustum-shaped outer shell 9. The gas discharged from the exhaust port 13 can reach the interior of the buffer chamber 5. Since the temperature inside the buffer chamber 5 is high, the gas is heated and becomes a hot air flow. At this time, at least three heat recovery pipes 7 are evenly installed between the buffer chamber 5 and the feed hopper 6, so that the hot air flow can reach the interior of the feed hopper 6, increasing the heat inside the feed hopper 6. When the scrap aluminum is fed through the feed hopper 6, it can be preheated by the hot air flow, thereby promoting the melting of the scrap aluminum inside the inner liner 23.

[0045] like Figure 1 and Figure 11 As shown, in this embodiment, the end of the heat recovery pipe 7 inserted into the feed hopper 6 should be provided with an upward-curving part 71. On the one hand, it can transport the hot air upward to preheat more waste aluminum, and on the other hand, it can prevent the hot air from flowing downward into the interior of the aluminum liquid below, which would cause bubble phenomenon.

[0046] Combination Figure 2 , Figure 9 and Figure 10 As shown, an integral conical hopper 61 is provided below the feed hopper 6. The lower end of the conical hopper 61 is fixedly connected to the upper end of the frustum-shaped outer shell 9, which facilitates the arrival of scrap aluminum into the interior of the frustum-shaped outer shell 9. In order to prolong the time that scrap aluminum spends inside the feed hopper 6 and enhance its preheating effect, baffles 20 are staggered inside the feed hopper 6, so that the scrap aluminum entering the feed hopper 6 can run along the baffles 20, prolonging the time that scrap aluminum spends inside the feed hopper 6. In order to enable the heat recovery hot airflow to reach any position inside the feed hopper 6, the baffles 20 are provided with dense through holes 202, so that the recovered hot airflow can reach the scrap aluminum through the through holes 202 for preheating.

[0047] To accelerate the discharge of hot air and ensure the rapid discharge of gas inside the frustum-shaped outer shell 9, a fixed ring 16 is fixed to the outer circumference of the frustum-shaped outer shell 9 located above the interior of the buffer chamber 5. A rotating ring 15 is rotatably mounted on the outside of the fixed ring 16 via a bearing. A guide fan 14 is fixed above the outer surface of the rotating ring 15. A guide fan drive structure 12 is provided on one side of the interior of the buffer chamber 5, which can drive the rotating ring 15 to rotate. Thus, the rotating ring 15 can drive the guide fan 14 to rotate by the action of the guide fan drive structure 12. When the guide fan 14 rotates, it can quickly transport the hot air inside the buffer chamber 5 to the interior of the heat recovery pipe 7.

[0048] like Figure 3 Preferably, in this embodiment, the guide fan drive structure 12 includes a second motor 121 installed inside one side of the buffer air chamber 5, a drive gear 122 fixed to the power output end of the second motor 121, and a driven gear 123 fixed below the rotating ring 15. The drive gear 122 and the driven gear 123 mesh, and the second motor 121 can drive the driven gear 123 to rotate, thereby realizing that the rotating ring 15 drives the guide fan 14 to rotate.

[0049] Continue to refer to Figure 2 , Figure 9 and Figure 10 In the above structure, scrap aluminum may get stuck on the baffle plate 20. To solve this problem, a mounting groove 201 is provided on the side of the baffle plate 20 near the inner wall of the feed hopper 6. A pin 19 is fixed inside the mounting groove 201. A mounting seat 21 is fixed on the inner wall of the feed hopper 6 at a position corresponding to the mounting groove 201. A torsion spring 22 is provided between the pin 19 and the mounting seat 21. The baffle plate 20 can be supported by the torsion spring 22 and the pin 19 to form a... Figure 9 As shown, when scrap aluminum is located on baffle plate 20, it is pressed down by the weight of the scrap aluminum (rotated at a certain angle along pin 19). Since the amount of scrap aluminum above baffle plate 20 is constantly changing during feeding, the weight on baffle plate 20 is also constantly changing. This state can achieve continuous shaking of baffle plate 20, thereby avoiding the situation where scrap aluminum gets stuck on baffle plate 20.

[0050] The working principle of this invention is as follows: When using this device, scrap aluminum is fed into the feed hopper 6. The scrap aluminum can reach the interior of the frustum-shaped outer shell 9 through the conical hopper 61. Under the action of the auger drive structure 11, the conical auger body 10 can push the scrap aluminum downward. Since the diameters of the conical auger body 10 and the frustum-shaped outer shell 9 gradually decrease, the scrap aluminum can be slightly compressed during its downward movement to increase the density of the compressed scrap (increased weight, thus allowing the molten aluminum to carry the scrap more quickly). The scrap aluminum flows downward and exits from the lower end of the frustum-shaped outer shell 9, and will reach the interior of the hollow cylinder formed by the vertically arranged rings 17, the connecting column 18, and the gap. Along this hollow... The cylinder continues to move downwards, vertically downwards at the center of the vortex. During this downward movement, some of the scrap aluminum is carried away by the vortex (at this time, this scrap aluminum can pass through the gaps and enter the molten aluminum to melt). This scrap aluminum can diffuse outwards along the guide plate 8, thus ensuring that this part of the scrap aluminum can melt at the initial height it is carried away (this is to ensure that the scrap aluminum can melt at every height of the molten aluminum, making the melting uniform). The other part of the scrap aluminum continues to move downwards until it reaches the bottom ring 17 and is discharged from below. This completes the entire process of the scrap aluminum being drawn into the molten aluminum. After the scrap aluminum is melted, it can be discharged from the discharge pipe 4 by opening the shut-off valve.

[0051] During the downward conveying of scrap aluminum by the conical auger body 10, the conical auger body 10 also compresses the external gas downwards. This gas can be discharged outwards through the exhaust port 13 during the downward compression and conveying of scrap aluminum by the conical auger body 10, reaching the interior of the buffer gas chamber 5. The guide fan 14 is driven to rotate by the guide fan drive structure 12. When the guide fan 14 rotates, it can quickly transport the hot air inside the buffer gas chamber 5 to the interior of the heat recovery pipe 7. The heat inside the heat recovery pipe 7 can reach the interior of the feed hopper 6 to preheat the scrap aluminum (the end of the heat recovery pipe 7 inserted into the feed hopper 6 should be provided with an upward-curved part 71, which...). On the one hand, it can transport the hot air upward to preheat more scrap aluminum, and on the other hand, it can avoid the hot air flowing downward into the interior of the aluminum liquid below, which would cause bubble phenomenon. When scrap aluminum is continuously fed, the scrap aluminum is deflected by the baffle plate 20, which prolongs the preheating time of the scrap aluminum. Under the action of the weight of the scrap aluminum, the baffle plate 20 can be pressed down (rotated at a certain angle along the pin shaft 19). Since the weight of the scrap aluminum above the baffle plate 20 is constantly changing during feeding, the weight on the baffle plate 20 is constantly changing. This state can realize the continuous shaking of the baffle plate 20, thereby avoiding the situation where scrap aluminum gets stuck in the baffle plate 20.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
