Description

Technical Field

[0001] This invention relates to the field of aluminum alloy waste filtration technology, and particularly to a device for filtering impurities from aluminum alloy waste smelting. Background Technology

[0002] In the industrial production process of aluminum alloy scrap remelting, impurities contained within the scrap can severely impact the quality of the final aluminum alloy product. For example, non-metallic impurities may reduce the strength and toughness of the aluminum alloy; metallic impurities may alter the chemical composition of the aluminum alloy, making it unable to meet specific industrial standards. Traditional filtration devices often suffer from low processing efficiency when dealing with these impurities. Due to the limited filtration methods, they cannot adequately separate different types of impurities. Furthermore, dead zones exist during the filtration process, resulting in some impurities not being effectively removed. Insufficient treatment not only affects product quality but may also increase the difficulty and cost of subsequent smelting processes, reducing production efficiency and economic benefits. Therefore, we propose an impurity filtration device for aluminum alloy scrap smelting to address these issues. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an aluminum alloy waste smelting impurity filtration device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A filter device for impurities in aluminum alloy waste smelting includes a support plate. Guide rails are fixed to both sides of the upper end of the support plate. Two track wheels are mounted on the upper end of each guide rail. A U-shaped movable frame is mounted on the upper end of the four track wheels. Air jet mechanisms are mounted on both sides of the upper end of the U-shaped movable frame. A swaying mechanism is connected to one side of the support plate. A filter barrel is rotatably connected to the middle of the support plate, with the air jet mechanisms corresponding to the two sides of the filter barrel. A mounting frame is mounted on the upper end of the support plate, and a crushing mechanism and a covering mechanism are mounted on the mounting frame. A magnetic suction structure is provided inside the filter barrel.

[0006] Preferably, the jetting mechanism includes two fixed pipes fixed to both sides of the upper end of the U-shaped movable frame. Two jet hoods are connected to one side of each fixed pipe, and a connecting pipe is connected between the two fixed pipes. Air pumps are fixed to both sides of the bearing plate. An air supply pipe is connected to the air supply end of one air pump on the same side. A connecting pipe is connected to one end of the air supply pipe. The four jet hoods on the same side correspond to the two ends of the filter barrel.

[0007] Preferably, the swaying mechanism includes a protective box fixed to one side of the upper end of the support plate, a vibration motor is installed inside the protective box, a connecting rod is installed on the vibration motor, and one end of the connecting rod is rotatably connected to one side of the U-shaped moving frame.

[0008] Preferably, a drive motor is installed at the lower end of the support plate, and the output shaft of the drive motor is connected to a rotating rod through a reduction mechanism. The upper end of the rotating rod passes through the side wall of the support plate and is fixed to the lower middle part of the filter barrel.

[0009] Preferably, the covering mechanism includes a cover connected to the perimeter of the mounting frame, and an air suction mechanism is connected to one side of the upper end of the mounting frame.

[0010] Preferably, the magnetic attraction structure includes multiple magnetic blocks that are fixed at equal intervals on the inner side wall of the filter barrel, and four magnetic blocks on the same side form a group, and a cover is hinged to one side of the filter barrel.

[0011] The operation process of this utility model is as follows:

[0012] 1. Waste crushing: When aluminum alloy waste needs to be filtered, the waste is first put into the crushing mechanism on the mounting frame. The crushing mechanism crushes the large pieces of aluminum alloy waste into smaller pieces, increasing the contact area between the waste and the filter device, which facilitates the subsequent impurity separation operation.

[0013] 2. Waste falls into the filter barrel: The crushed small pieces of waste fall from the crushing mechanism into the filter barrel that is rotatably connected in the middle of the support plate, and the impurities are separated in the filter barrel;

[0014] 3. Filter barrel rotation: The drive motor at the lower end of the support plate starts, and its output shaft drives the rotating rod to rotate through the reduction mechanism. The upper end of the rotating rod is fixed in the middle of the lower end of the filter barrel, thereby driving the filter barrel to rotate. The rotation of the filter barrel can make the waste inside tumble continuously, increasing the contact opportunity between the waste and the air jet mechanism, magnetic attraction structure, etc., and improving the effect of impurity separation.

[0015] 4. Jet operation: The air pumps on both sides of the support plate are started, and the gas is delivered to the connecting pipe through the air supply pipe. The gas is then distributed by the connecting pipe to the jet hoods fixed on the fixed pipes on both sides of the upper end of the U-shaped moving frame. The four jet hoods on the same side correspond to the two ends of the filter barrel. When the filter barrel rotates, the jet hoods spray gas into the barrel, blowing up the non-metallic impurities inside.

[0016] 5. Reciprocating movement of the jet mechanism: The vibration motor inside the protective box starts, driving the connecting rod to move. One end of the connecting rod is rotatably connected to one side of the U-shaped moving frame, thereby driving the U-shaped moving frame to reciprocate on both sides of the upper end of the bearing plate. Since the jet mechanism is installed on the U-shaped moving frame, the jet mechanism also reciprocates, expanding the jet range and reducing the dead angle of filtration.

[0017] 6. Adsorption of non-metallic impurities: The suction mechanism on one side of the upper end of the mounting frame is activated to adsorb the dust and other non-metallic materials blown up by the jet mechanism in the filter barrel, further removing non-metallic impurities from the waste.

[0018] 7. Adsorption of metal impurities: Multiple magnetic blocks are fixed at equal intervals on the inner side wall of the filter barrel. Four magnetic blocks on the same side form a group. During the rotation of the filter barrel, the magnetic blocks adsorb the metal impurities inside, separating the metal impurities from the aluminum alloy waste.

[0019] 8. Cleaning and Maintenance: After filtration is complete, open the hinged cover on one side of the filter canister to clean the remaining waste and adsorbed impurities inside. At the same time, regularly inspect and maintain each component to ensure the normal operation of the device.

[0020] This utility model has the following advantages:

[0021] 1. The crushing mechanism breaks the waste into small pieces, increasing the contact area between the waste and the filter device. The drive motor rotates the filter barrel, causing the waste to tumble continuously. The combination of the jetting mechanism and the shaking mechanism expands the jetting range, which can accelerate the separation of impurities and improve the filtration efficiency.

[0022] 2. The jetting mechanism blows up non-metallic impurities, the suction mechanism adsorbs them, and the magnetic block adsorbs metallic impurities. Impurities in the waste are separated from different angles, effectively avoiding dead corners in filtration, making impurity treatment more thorough, and improving the purity of aluminum alloy waste.

[0023] 3. After thorough filtration, the impurity content of aluminum alloy scrap is significantly reduced, resulting in more stable quality aluminum alloy products after remelting.

[0024] In summary, this invention can accelerate the separation of impurities, improve the efficiency of filtration, and make the impurity treatment more thorough, thereby increasing the purity of aluminum alloy waste. In addition, the efficient and thorough filtration reduces the production difficulty and cost increase caused by impurities in the subsequent smelting process, improves production efficiency, reduces energy consumption and raw material waste, and thus reduces the overall production cost.

[0037] A drive motor 14 is installed at the lower end of the support plate 12. The output shaft of the drive motor 14 is connected to a rotating rod 15 through a reduction mechanism. The upper end of the rotating rod 15 passes through the side wall of the support plate 12 and is fixed to the lower middle part of the filter barrel 1. The drive motor 14 drives the reduction mechanism to rotate through the rotation of the output shaft, thereby driving the rotating rod 15 to rotate, thus realizing the rotation of the filter barrel 1.

[0040] The operation process of this utility model is as follows:

[0041] 1. Waste crushing: When aluminum alloy waste needs to be filtered, the waste is first placed into the crushing mechanism 18 on the mounting frame 17.

[0044] 4. Jet operation: The air pumps 10 on both sides of the support plate 12 are started, and the gas is delivered to the connecting pipe 4 through the air supply pipe 9. The gas is then distributed by the connecting pipe to the jet hoods 3 fixed on the fixed pipes 2 on both sides of the upper end of the U-shaped moving frame 5. The four jet hoods on the same side correspond to the two ends of the filter barrel 1. When the filter barrel rotates, the jet hoods spray gas into the barrel, blowing up the non-metallic impurities inside.

[0045] 5. Reciprocating movement of the jet mechanism: The vibration motor inside the protective box 6 starts, driving the connecting rod 16 to move. One end of the connecting rod is rotatably connected to one side of the U-shaped moving frame 5, thereby driving the U-shaped moving frame to reciprocate on both sides of the upper end of the bearing plate 12. Since the jet mechanism is installed on the U-shaped moving frame, the jet mechanism also reciprocates, expanding the jet range and reducing the dead angle of filtration.

[0046] 6. Adsorption of non-metallic impurities: The suction mechanism 19 on one side of the upper end of the mounting frame 17 is activated to adsorb the dust and other non-metallic materials blown up by the jet mechanism in the filter bucket, and further remove non-metallic impurities from the waste.
