Description

Technical Field

[0001] The present invention relates to the field of aluminum slag processing equipment, in particular to a high-efficiency heating aluminum slag separation device. Background Art

[0002] Modern society's demand for aluminum and its alloys continues to increase. Aluminum and its alloys are widely used in construction, aviation, power transmission, automobile manufacturing, household appliances, and other fields. With the rapid development of aluminum alloy processing companies, these companies have generated a large amount of waste aluminum slag during the aluminum alloy smelting process. Aluminum slag, as an important secondary aluminum resource, contains 20% to 60% aluminum. Currently, most aluminum slag separation processes involve direct stirring with stirring blades. This results in slow stirring and a significant time consumption, significantly reducing separation efficiency. Furthermore, during the stirring process, a combustion aid is typically added to assist in heating and combustion. This slows the heating rate of the combustion aid, while also dissipating the temperature quickly, causing the molten aluminum to agglomerate again, severely impacting work efficiency. Furthermore, this method results in a large amount of residue remaining after the slag separation, resulting in incomplete separation. Summary of the Invention

A drive component, a smoke exhaust component and a An air inlet assembly is provided on one side of the driving assembly, and the driving assembly is connected to a rotating shaft 5, which passes through the partition 2 and is fixedly connected to the partition 2. The rotating shaft 5 extends into the mixing chamber. Driven by the driving assembly, the rotating shaft 5 rotates, driving the partition 2 to rotate. During the feeding and mixing process, the first solenoid valve 3 is closed and the second solenoid valve 4 is opened. At the same time, the air inlet assembly introduces air. During the mixing process, the second solenoid valve 4 performs circumferential rotation, so that the air outlet direction is constantly changed, thereby increasing the coverage area of the air inlet to the mixing chamber. Since the introduced air contains oxygen, it can further play the role of a combustion-supporting burner 8. At the same time, since the air is introduced downward from the top, the heat in the mixing chamber can be squeezed downward to prevent excessive heat dissipation.

[0031] The stirring chamber includes a first stirring section 6 and a second stirring section 7 fixed at the bottom end of the first stirring section 6. The stirring process is carried out synchronously in two stages. A combustion burner 8 and a feeding assembly are respectively provided on the opposite side walls of the first stirring section 6, and the injection end of the combustion burner 8 extends into the first stirring section 6.

During the stirring process, the third solenoid valve is closed, and the aluminum liquid and the residue are stirred and separated by the stirring paddle 12 driven by the rotating shaft 5. The discharge port 13 is located in the first-level collecting mechanism. When the third solenoid valve is opened, the aluminum liquid can flow out and flow into the first-level collecting mechanism.

[0032] A further optimized solution is that the driving component includes a first motor 14, and a heat-resistant box 15 is provided on the outer side of the first motor 14. The heat-resistant box 15 can protect the motor and is mounted in the smoke exhaust chamber 1 through a connecting rod 16. The output shaft of the first motor 14 passes through the bottom end of the heat-resistant box 15 and is fixedly connected to the rotating shaft 5. The first motor 14 drives the rotating shaft 5 to rotate; the air intake component includes a blower 17 fixed on the outside of the smoke exhaust chamber 1, and the blower 17 is connected to a first air duct 18. The first air duct 18 extends into the smoke exhaust chamber 1 and is connected to an annular air duct 19. The annular air duct 19 is sleeved on the outside of the rotating shaft 5. The bottom end of the annular air duct 19 is circumferentially fixed with a number of second air ducts 20. The second air duct 20 is arranged correspondingly to the second solenoid valve 4 above and below. The outside air is introduced into the first air duct 18 through the blower 17, and the annular air duct 19 is used to avoid it from contacting the rotating shaft. The interference of the shaft 5, and the use of the annular air duct 19 can be used to arrange the second air duct 20 corresponding to the second solenoid valve 4 along its bottom surface, and the air is supplied to the opened second solenoid valve 4 in an intermittent manner during the rotation of the partition 2. The first solenoid valve 3 is closed here to make the introduced wind concentrated and sprayed to the second solenoid valve 4 to prevent it from entering from other places and affecting the injection rate and pressure; the smoke exhaust component includes a smoke exhaust pipe 21, one end of the smoke exhaust pipe 21 is connected to an external smoke collector (not shown in the figure), and the other end of the smoke exhaust pipe 21 passes through the top wall of the smoke exhaust chamber 1 and is fixed with a smoke hood 22. The smoke hood 22 is located on the top of the heat-resistant box 15. When the stirring is completed, a large amount of smoke is accumulated in the stirring chamber, the first solenoid valve 3 is opened, and the second solenoid valve 4 remains open. The external smoke collector sucks air to recycle the smoke in the stirring chamber. The external smoke collector is a prior art and will not be described in detail.

[0033] To further optimize the solution, the feeding assembly includes a feeding hopper 23, which is fixed to the side wall of the first stirring section 6, and the feeding end of the feeding hopper 23 is axially connected to a cover plate 24. The discharge end of the feeding hopper 23 is connected to the side wall of the first stirring section 6, and a sloped platform 25 is fixed at the connection between the discharge end of the feeding hopper 23 and the first stirring section 6. The sloped platform 25 is arranged corresponding to the injection end of the combustion burner 8. After opening the cover plate 24, the feeding hopper 23 is fed into the aluminum slag along the sloped platform 25 into the first stirring section 6. The height of the combustion burner 8 corresponds to the sloped platform 25 to prevent it from interfering with the frame 27.

[0034] A further optimized solution is provided, in which hydraulic cylinders 26 are fixed to the bottom of the two opposite side walls of the first stirring section 6, and the two hydraulic cylinders 26 are arranged opposite to each other. A frame 27 is fixed to the output end of the hydraulic cylinder 26, and the bottom surface of the frame 27 abuts against the top surface of the first stirring section 6, and the side surface of the frame 27 abuts against the inner wall of the first stirring section 6. The frame 27 is partially conformed to the bottom of the first stirring section 6, and the inclined platform 25 is located at the top of the frame 27. The disturbance assembly, the rotating shaft 5 and the first screen 9 are located between the two frames 27. The opposite sides of the two frames 27 are open. Under the push of the hydraulic cylinder 26, the two frames 27 push the aluminum slag to gather, and the side edges of the frame 27 have sufficient height to prevent it from splashing out and being unable to be handled during the disturbance process.

[0035] Further optimization scheme, the disturbance component includes a first shaft seat 28, the first shaft seat 28 is fixed on the top surface of the slider 11, the top surface of the first shaft seat 28 is axially connected with a disturbance rod 29, the top of the disturbance rod 29 is fixed with the output shaft of the second motor 30, and the disturbance rod 29 is fixed with a plurality of disturbance paddles 31.

The second motor 30 is fixed on the connecting arm 3 2, and the outer side of the second motor 30 is also covered with a heat-resistant box (not shown in the figure), which is arranged in the same manner as the first motor 14. The connecting arm 32 performs a circular motion with the rotating shaft 5 as the center. At the same time, the second motor 30 drives the disturbance rod 29 to rotate, so that it disturbs the aluminum slag located between the frame 27 along the circumferential direction. Under the strong combustion-supporting effect of the combustion burner 8, the metallic aluminum in the aluminum slag can be quickly melted during the disturbance process. At the same time, the external wind blows to the aluminum slag at intervals to assist the disturbance and combustion.

[0036] To further optimize the solution, the stirring paddle 12 is set at an angle, and the end of the stirring paddle 12 connected to the rotating shaft 5 is higher than the other end of the stirring paddle 12, so as to improve the stirring and separation efficiency. The bottom end of the rotating shaft 5 is connected to the second shaft seat 33, and the second shaft seat 33 is fixed at the center position of the bottom wall of the second stirring part 7. The second shaft seat 33 is used to fix the position of the bottom end of the rotating shaft 5.

[0037] A further optimized solution is provided, in which the bottom surface of the second stirring part 7 is set to a hemispherical surface, and a plurality of discharge ports 13 are opened on the bottom surface of the second stirring part 7. A second screen 34 is embedded in the discharge port 13, and the second screen 34 is arranged inside the third solenoid valve. After stirring is completed, the speed of the first motor 14 is reduced, and the third solenoid valve is opened at the same time to throw out the molten aluminum. At the same time, under the cooperation of the hemispherical bottom surface and the position of the discharge port 13 as shown in the figure, the molten aluminum can be quickly thrown out of the second stirring part 7 by centrifugal force, and flow out of the discharge port 13 after passing through the second screen 34.

The height of the connection between the first stirring part 6 and the second stirring part 7 is not higher than the height of the box wall of the collection box 35, which can prevent the thrown-out molten aluminum from endangering the personal safety of the staff. Brackets 36 are fixed on both sides of the first stirring part 6, and the brackets 36 are fixed on the outer wall of the collection box 35.

[0038] Further optimization scheme, the secondary collection mechanism includes an aluminum liquid transfer bag 37, a transfer chute 39 and a delivery pipe 40 arranged in the trench 38. The bottom end of the collection box 35 is connected to the delivery pipe 40. The bottom surface of the inner side of the collection box 35 is set as an inclined surface. The lowest point of the inclined surface is connected to the delivery pipe 40. The delivery pipe 40 is arranged in a vertical direction, and the end of the delivery pipe 40 away from the collection box 35 extends into the trench 38 and is connected to the transfer chute 39. The end of the transfer chute 39 is provided with a siphon component. The siphon pipe 41 of the siphon component is arranged in a vertical direction. The siphon pipe 41 extends out of the trench 38 and is connected to the aluminum liquid transfer bag 37. A trench 38 is dug on the ground, and an insulation layer is used above the trench 38 to isolate it from the outside world. Under the action of gravity, the molten aluminum flows to the lowest point of the bottom of the collection box 35, and enters the conveying pipe 40, and falls vertically to the transfer chute 39. The transfer chute 39 is set at an angle, and the aluminum liquid is transferred by gravity. The entire transfer process is transported in the trench 38, which has a good insulation effect and prevents the aluminum liquid from solidifying quickly. The aluminum liquid is sucked into the aluminum liquid transfer bag 37 for storage through the siphon pipe 41, that is, the aluminum liquid can be reused. The siphon component is set at the feed of the aluminum liquid transfer bag 37, and it is an existing device and will not be described in detail.

[0039] To further optimize the solution, the part of the rotating shaft 5 located in the first stirring section 6 and the inner wall of the collecting box 35 are covered with an insulation layer 42. The insulation layer 42 of the part of the rotating shaft 5 located in the first stirring section 6 can prevent the rotating shaft 5 from being damaged by the combustion burner 8, and the insulation layer 42 inside the collecting box 35 can reduce heat loss.

[0040] The above-mentioned solenoid valves, motors and other electrical components of this device are all controlled by PLC. The specific electrical connection method, that is, the control method, is existing technology and will not be repeated here.
