Description

Technical Field

[0001] This invention relates to the field of aluminum ash treatment technology, specifically to a crushing pretreatment equipment and process for the harmless treatment of blocky aluminum ash. Background Technology

[0002] Aluminum ash is a product of the slag produced in the electrolytic aluminum or cast aluminum production process, which is cooled and processed. It contains aluminum and a variety of valuable elements and is a renewable resource. Aluminum ash is mainly composed of a mixture of metallic aluminum, oxides and salt solvents. If it is not recycled, it will not only waste resources but also pollute the environment.

[0003] When pre-processing and crushing block aluminum ash, the aluminum ash accumulates at the bottom of the crushing tank. As a result, a large amount of aluminum ash will aggregate during the crushing process, which will interfere with the normal discharge of aluminum ash. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention is: a crushing pretreatment equipment and process for the harmless treatment of blocky aluminum ash, comprising: The tank body has a support leg fixedly connected to the bottom, a feeding shell fixedly connected to the top, a first motor fixedly connected to the top of the feeding shell, and crushing blocks evenly arranged on the inner wall of the tank body. The crushing component is used to crush block aluminum ash. A screening component is provided at the bottom of the crushing component. The side of the screening component is fixedly connected to the tank body. A discharge component is fixedly connected to the bottom of the screening component. The top of the crushing component is fixedly connected to the bottom of the feeding shell, and the top of the screening component is fixedly connected to the bottom of the tank. The crushing component includes a rotating rod, the side of which is rotatably connected to the inner wall of a support, the top of which is fixedly connected to the output end of a first motor, crushing blades fixedly connected to the side of the rotating rod, a connecting shaft fixedly connected to the side of the rotating rod, a crushing roller rotatably connected to the side of the connecting shaft, and a contact mechanism fixedly connected to the side of the rotating rod. The contact mechanism is intersected with the connecting shaft. By turning on the first motor, the output end of the first motor drives the rotating rod to rotate, thereby causing the rotating rod to drive the crushing blades to crush the blocky aluminum ash in the tank. At the same time, the crushing blades rotate within the inner cavity of the tank via the rotating rod, causing the crushing blades to crush the blocky aluminum ash, thus fully crushing the blocky aluminum ash in the tank. Simultaneously, the rotation of the rotating rod drives the connecting shaft to rotate, thereby causing the connecting shaft to drive the crushing roller to rotate on the filter screen, thus crushing the blocky aluminum ash accumulated on the filter screen. Simultaneously, the rotation of the rotating rod drives the contact mechanism to rotate on the filter screen.

[0005] The contact mechanism includes a contact rod, the side of which is fixedly connected to the inner wall of a rotating rod. A contact block is fixedly connected to the end of the contact rod away from the rotating rod. A bent plate is fixedly connected to the side of the contact block. A connecting shaft is fixedly connected to the side of the contact rod. A round block is fixedly connected to the end of the connecting shaft away from the contact rod. The rotating rod drives the contact rod to rotate, causing the contact rod to move and contact the contact block with the inner wall of the tank. This allows the scraper to scrape and clean the inner wall of the tank, thus preventing the powdery aluminum ash generated during the crushing of blocky aluminum ash from accumulating and remaining on the inner wall of the tank. At the same time, when the rotating rod drives the contact rod to rotate within the inner cavity of the tank, the round block on the contact rod contacts and agitates the aluminum ash in the tank through the connecting shaft, thus preventing the crushed aluminum ash from clumping together in the inner cavity of the tank.

[0006] Preferably, the screening component includes a screening shell, the top of which is fixedly connected to the bottom of the tank. Electro-hydraulic rods are fixedly connected to both sides of the tank. A connecting arm is fixedly connected to the output end of each electro-hydraulic rod. A sliding rod is fixedly connected to the side of the connecting arm away from the electro-hydraulic rod. The side of the sliding rod is slidably connected to the inner wall of a sliding groove. Sliding grooves are symmetrically formed on the side of the screening shell. A filter screen plate is fixedly connected to the end of the sliding rod away from the connecting arm. A connecting frame is fixedly connected to the inner wall of the screening shell. A fixing rod is fixedly connected to the axis of the connecting frame. The top of the fixing rod is slidably connected to the bottom of a rotating rod. The side of the fixing rod is slidably connected to the inner wall of the filter screen plate. A first spring is sleeved on the fixing rod. The top of the first spring is fixedly connected to the bottom of the filter screen plate, and the bottom of the first spring is fixedly connected to the connecting frame. The top of the connecting frame is fixedly connected, and a clearing mechanism is fixedly connected to the top of the connecting frame. When crushing the blocky aluminum ash in the tank, the electric hydraulic rod is opened, and the output end of the electric hydraulic rod drives the connecting arm to move back and forth. This causes the connecting arm to drive the filter plate to perform screening work through the sliding rod, thereby screening the crushed aluminum ash. At the same time, when the filter plate moves back and forth in the screening shell, when the connecting arm drives the filter plate to slide upward on the fixed rod, the bottom of the filter plate contacts the side of the crushing roller, which facilitates the crushing roller to crush the blocky aluminum ash screened on the filter plate. When the connecting arm drives the filter plate to slide downward on the fixed rod, the filter plate cleans the clearing mechanism on the connecting frame, thereby preventing uncrushed aluminum blocks from getting stuck in the mesh of the filter plate when screening the blocky aluminum ash.

[0007] Preferably, the unblocking mechanism includes an unblocking rod, the bottom of which is fixedly connected to the top of the connecting frame, a pin fixedly connected to the top of the unblocking rod, and a scraper fixedly connected to the side of the unblocking rod. The scraper has evenly spaced square grooves on its side. When the filter plate moves downwards, the mesh openings of the filter plate are pressed against the top of the pin, allowing the pin to push out the aluminum block stuck in the mesh openings. Simultaneously, the scraper scrapes and cleans the inner wall of the mesh openings. The evenly spaced square grooves on the side of the scraper allow aluminum ash generated during crushing to slide out through the grooves when the scraper comes into contact with the mesh openings, thus preventing interference with the normal passage of aluminum ash during cleaning of the mesh openings.

[0008] Preferably, the discharge component includes a discharge shell, a spraying mechanism fixedly connected to the top of the discharge shell, a second motor fixedly connected to the inner wall of the connecting frame, a rotating shaft fixedly connected to the output end of the second motor, a rotating frame fixedly connected to the bottom of the rotating shaft, a discharge trough formed on the inner wall of the discharge component, and a magnetic screen fixedly connected to the inner wall of the discharge trough. The sieved aluminum ash falls downwards. By turning on the second motor, the output end of the second motor drives the rotating shaft to rotate the rotating frame within the inner cavity of the discharge shell, thereby causing the rotating frame to process the crushed aluminum ash. The impact disperses the aluminum ash, and the rotating frame, while rotating, compresses it against the spraying mechanism, thus spraying and reducing dust during the discharge process. The aluminum ash, containing various impurities including iron, is thoroughly dispersed by the impact of the rotating frame against the sieved aluminum ash. Simultaneously, a magnetic screen is installed, allowing the aluminum ash to fall onto the screen and adsorb any trace iron elements adhering to it. The aluminum ash then exits through the mesh of the magnetic screen, preventing residual iron impurities from remaining in the crushed aluminum ash.

[0009] Preferably, the spraying mechanism includes a water tank, the top of which is fixedly connected to the bottom of the screening shell, and the bottom of which is fixedly connected to the top of the discharge shell. A water storage trough is formed on the inner wall of the water tank. A pressing rod is inserted into the side of the water tank. A pressing plate is fixedly connected to the end of the pressing rod away from the water storage trough, and an arc plate is fixedly connected to the end of the pressing rod near the water storage trough. A second spring is sleeved on the pressing rod. The end of the second spring away from the water tank is fixedly connected to the pressing plate, and the other end of the second spring is fixedly connected to the side of the water tank. Spraying grooves are evenly formed on the side of the water tank, and spray heads are fixedly connected to the inner wall of the spraying grooves. A rotating frame rotates within the discharge shell, pressing the pressing plate as it rotates. This causes the pressing plate to move the arc plate within the water storage tank, allowing water in the tank to be sprayed out through the spray heads. This effectively reduces dust generated when the rotating frame collides with the aluminum ash during the separation and discharge process.

[0010] A crushing pretreatment process for the harmless treatment of blocky aluminum ash includes the following steps: S1: Place the block aluminum ash into the tank through the feeding shell; S2: Turn on the first motor to drive the crushing components to crush the blocky aluminum ash; S3: The crushed block aluminum ash is screened by the screening component; S4: The sieved aluminum ash is discharged through the discharge component. The beneficial effects of this invention are as follows: 1. This invention, by setting up a contact mechanism, uses a rotating rod to drive a contact rod to rotate, thereby causing the contact rod to move and contact the contact block with the inner wall of the tank. This allows the scraper to scrape and clean the inner wall of the tank, thus preventing the powdery aluminum ash generated during the crushing of blocky aluminum ash from accumulating and remaining on the inner wall of the tank. At the same time, when the rotating rod drives the contact rod to rotate in the inner cavity of the tank, the round block on the contact rod contacts and agitates the aluminum ash in the tank through the connecting shaft, thereby preventing the crushed aluminum ash from agglomerating in the inner cavity of the tank.

[0011] 2. This invention, by setting up a blockage-clearing mechanism, causes the filter plate to move downwards, resulting in the mesh openings of the filter plate being pressed against the top of the ejector pin. This allows the ejector pin to push out the aluminum block stuck in the mesh openings of the filter plate. At the same time, the scraper can scrape and clean the inner wall of the mesh openings of the filter plate. Furthermore, square grooves are evenly provided on the side of the scraper, so that when the scraper comes into contact with the mesh openings of the filter plate, the aluminum ash generated during the crushing process can slide out through the square grooves, thus avoiding interference with the normal passage of aluminum ash when cleaning the mesh openings of the filter plate.

[0012] 3. This invention, by setting up a discharge component, addresses the issue that aluminum ash contains various impurities, including various iron elements. The rotating frame impacts the sieved aluminum ash, causing it to disperse sufficiently. Simultaneously, a magnetic screen is used, allowing the aluminum ash impacted by the rotating frame to fall onto the magnetic screen, which then adsorbs trace amounts of iron elements adhering to the aluminum ash. The aluminum ash is then discharged through the mesh of the magnetic screen, thus preventing residual iron impurities in the crushed aluminum ash.

[0013] 4. This invention, by setting up a spraying mechanism, uses a rotating frame that rotates within the inner cavity of the discharge shell. As the rotating frame rotates, it presses against the extrusion plate, causing the extrusion plate to move within the inner cavity of the water tank. This allows water in the tank to be sprayed out through the spray nozzles, thus enabling dust suppression by spraying when the rotating frame collides with the aluminum ash during the separation and discharge process.

Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0016] Example 1, using Figures 1-9 The following describes a crushing pretreatment equipment and process for the harmless treatment of block aluminum ash according to an embodiment of the present invention.

[0017] like Figures 1-9 The present invention discloses a crushing pretreatment device and process for the harmless treatment of blocky aluminum ash, comprising: Tank 1, with a support leg 2 fixedly connected to the bottom of the tank 1, a feeding shell 3 fixedly connected to the top of the tank 1, a first motor 5 fixedly connected to the top of the feeding shell 3, and crushing blocks 9 evenly arranged on the inner wall of the tank 1. Crushing component 6 is used to crush block aluminum ash. A screening component 7 is provided at the bottom of the crushing component 6. The side of the screening component 7 is fixedly connected to the tank body 1. A discharge component 8 is fixedly connected to the bottom of the screening component 7. The top of the crushing component 6 is fixedly connected to the bottom of the feeding shell 3, and the top of the screening component 7 is fixedly connected to the bottom of the tank 1. The crushing component 6 includes a rotating rod 61, the side of which is rotatably connected to the inner wall of the support 4, the top of which is fixedly connected to the output end of the first motor 5, crushing blades 62 fixedly connected to the side of the rotating rod 61, a connecting shaft 63 fixedly connected to the side of the rotating rod 61, a crushing roller 64 rotatably connected to the side of the connecting shaft 63, and a contact mechanism 65 fixedly connected to the side of the rotating rod 61. The contact mechanism 65 and the connecting shaft 63 are arranged crosswise. By turning on the first motor 5, the output end of the first motor 5 drives the rotating rod 61 to rotate, thereby causing the rotating rod 61 to drive the crushing blades. 62 crushes the lumpy aluminum ash in the tank 1. Simultaneously, the crushing blade 62 rotates within the inner cavity of the tank 1 via the rotating rod 61, causing the crushing blade 62 to compress the lumpy aluminum ash fragments 9, thus fully crushing the lumpy aluminum ash in the tank 1. At the same time, the rotation of the rotating rod 61 drives the connecting shaft 63 to rotate, which in turn drives the crushing roller 64 to rotate on the filter screen plate 76, thereby compressing and crushing the lumpy aluminum ash accumulated on the filter screen plate 76. Simultaneously, the rotation of the rotating rod 61 drives the contact mechanism 65 to rotate on the filter screen plate 76.

[0018] The contact mechanism 65 includes a contact rod 651, the side of which is fixedly connected to the inner wall of the rotating rod 61. A contact block 652 is fixedly connected to the end of the contact rod 651 away from the rotating rod 61. A bent plate 653 is fixedly connected to the side of the contact block 652. A connecting shaft 654 is fixedly connected to the side of the contact rod 651. A round block 655 is fixedly connected to the end of the connecting shaft 654 away from the contact rod 651. The rotating rod 61 drives the contact rod 651 to rotate, thereby causing the contact rod 651 to drive the contact... Block 652 moves in contact with the inner wall of tank 1, causing scraper 793 to scrape and clean the inner wall of tank 1, thereby preventing the powdery aluminum ash generated during the crushing of block aluminum ash from accumulating and remaining on the inner wall of tank 1. At the same time, when rotating rod 61 drives contact rod 651 to rotate in the inner cavity of tank 1, the round block 655 on contact rod 651 contacts and turns the aluminum ash in tank 1 through connecting shaft 654, thereby preventing the crushed aluminum ash from agglomerating in the inner cavity of tank 1.

[0019] The screening component 7 includes a screening shell 71. The top of the screening shell 71 is fixedly connected to the bottom of the tank body 1. Electro-hydraulic rods 72 are fixedly connected to both sides of the tank body 1. A connecting arm 73 is fixedly connected to the output end of the electro-hydraulic rod 72. A sliding rod 75 is fixedly connected to the side of the connecting arm 73 away from the electro-hydraulic rod 72. The side of the sliding rod 75 is slidably connected to the inner wall of the sliding groove 74. Sliding grooves 74 are symmetrically provided on the side of the screening shell 71. A filter screen plate 76 is fixedly connected to the end of the sliding rod 75 away from the connecting arm 73. A connecting frame 77 is fixedly connected to the inner wall of the screening shell 71. A fixing rod 78 is fixedly connected to the axis of the connecting frame 77. The top of the fixing rod 78 is slidably connected to the bottom of the rotating rod 61. The side of the fixing rod 78 is slidably connected to the inner wall of the filter screen plate 76. A first spring 710 is sleeved on the fixing rod 78. The top of the first spring 710 is fixedly connected to the bottom of the filter screen plate 76. The bottom of the first spring 710 is fixedly connected to the top of the connecting frame 77. A clearing mechanism 79 is fixedly connected to the top of the connecting frame 77. When crushing the blocky aluminum ash in the tank 1, the electric hydraulic rod 72 is activated, and its output drives the connecting arm 73 to reciprocate. This causes the connecting arm 73 to drive the filter screen 76 via the sliding rod 75 for screening, thus screening the crushed aluminum ash. Simultaneously, as the filter screen 76 reciprocates within the screening shell 71, the connecting arm 73 drives the filter screen 76... When the filter screen 76 slides upward on the fixed rod 78, the bottom of the filter screen 76 contacts the side of the crushing roller 64, which facilitates the crushing roller 64 to crush the blocky aluminum ash screened on the filter screen 76. When the connecting arm 73 drives the filter screen 76 to slide downward on the fixed rod 78, the filter screen 76 cleans the blockage removal mechanism 79 on the connecting frame 77, thereby preventing uncrushed aluminum blocks from getting stuck in the mesh of the filter screen 76 during the screening of blocky aluminum ash.

[0020] The unblocking mechanism 79 includes an unblocking rod 791, the bottom of which is fixedly connected to the top of the connecting frame 77. A pin 792 is fixedly connected to the top of the unblocking rod 791, and a scraper 793 is fixedly connected to the side of the unblocking rod 791. Square grooves 794 are evenly distributed on the side of the scraper 793. When the filter plate 76 moves downward, the mesh of the filter plate 76 is pressed against the top of the pin 792, so that the pin 792 can push out the aluminum block stuck in the mesh of the filter plate 76. At the same time, the scraper 793 can scrape and clean the inner wall of the mesh of the filter plate 76. The square grooves 794 are evenly distributed on the side of the scraper 793, so that when the scraper 793 abuts against the mesh of the filter plate 76, the aluminum dust generated during the crushing can slide out through the square grooves 794, thereby avoiding interference with the normal passage of aluminum dust when cleaning the mesh of the filter plate 76.

[0021] Example 2, using Figures 1-10 The following describes the crushing and pretreatment equipment and process for the harmless treatment of blocky aluminum ash according to the present invention. like Figures 1-10 This invention provides a crushing pretreatment device and process for the harmless treatment of blocky aluminum ash, based on Example 1. The discharge component 8 includes a discharge housing 82. A spraying mechanism 81 is fixedly connected to the top of the discharge housing 82. A second motor 83 is fixedly connected to the inner wall of the connecting frame 77. A rotating shaft 84 is fixedly connected to the output end of the second motor 83. A rotating frame 85 is fixedly connected to the bottom of the rotating shaft 84. A discharge trough 86 is formed on the inner wall of the discharge component 8. A magnetic screen 87 is fixedly connected to the inner wall of the discharge trough 86. After screening, the aluminum ash falls downwards. By turning on the second motor 83, the output end of the second motor 83 drives the rotating shaft 84 to drive the rotating frame 85 to rotate in the inner cavity of the discharge housing 82, thereby causing the rotating frame 85 to process the crushed aluminum ash. The aluminum ash is dispersed by impact, and the rotating frame 85 squeezes against the spraying mechanism 81 as it rotates, thus spraying and reducing dust during discharge. The aluminum ash impacted by the rotating frame 85 contains various impurities, including various iron elements. The impact between the rotating frame 85 and the screened aluminum ash causes the screened aluminum ash to be fully dispersed. At the same time, a magnetic screen 87 is set up, and the aluminum ash impacted by the rotating frame 85 falls onto the magnetic screen 87, allowing the magnetic screen 87 to adsorb the trace iron elements attached to the aluminum ash. The aluminum ash is discharged through the mesh of the magnetic screen 87, thus avoiding the presence of residual iron impurities in the crushed aluminum ash.

[0022] The spraying mechanism 81 includes a water tank 811. The top of the water tank 811 is fixedly connected to the bottom of the screening shell 71, and the bottom of the water tank 811 is fixedly connected to the top of the discharge shell 82. A water storage tank 812 is provided on the inner wall of the water tank 811. A pressing rod 813 is inserted into the side of the water tank 811. A pressing plate 814 is fixedly connected to the end of the pressing rod 813 away from the water storage tank 812. An arc plate 815 is fixedly connected to the end of the pressing rod 813 near the water storage tank 812. A second spring 816 is sleeved on the pressing rod 813. The end of the second spring 816 away from the water tank 811 is fixedly connected to the pressing plate 814. The other end of 6 is fixedly connected to the side of the water tank 811. The side of the water tank 811 is evenly provided with spray grooves 817, and the inner wall of the spray grooves 817 is fixedly connected with spray heads 818. The rotating frame 85 rotates in the inner cavity of the discharge shell 82. When the rotating frame 85 rotates, it squeezes the extrusion plate 814, so that the extrusion plate 814 drives the arc plate 815 to move in the inner cavity of the water tank 811, so that the water in the water tank 811 is sprayed out through the spray head 818. Thus, when separating and discharging aluminum ash, the dust generated when the rotating frame 85 collides with the aluminum ash can be sprayed to reduce dust.

[0023] A crushing pretreatment process for the harmless treatment of blocky aluminum ash includes the following steps: S1: The blocky aluminum ash is fed into the tank 1 through the feeding shell 3; S2: Turn on the first motor 5 to drive the crushing component 6 to crush the blocky aluminum ash; S3: The crushed block aluminum ash is screened by screening component 7; S4: The sieved aluminum ash is discharged through the discharge component 8.

[0024] The specific workflow is as follows: The block aluminum ash is placed into the tank 1, and the first motor 5 is turned on to drive the crushing component 6 to crush the block aluminum ash that has entered the tank 1. The crushed block aluminum ash is then screened by the screening component 7, so that the qualified block aluminum ash is discharged through the discharge component 8. By turning on the first motor 5, the output of the first motor 5 drives the rotating rod 61 to rotate, thereby causing the rotating rod 61 to drive the crushing blade 62 to crush the blocky aluminum ash in the tank 1. At the same time, the crushing blade 62 rotates in the inner cavity of the tank 1 through the rotating rod 61, and at the same time, the crushing blade 62 drives the blocky aluminum ash crushed pieces 9 to be squeezed, thereby fully crushing the blocky aluminum ash in the tank 1. At the same time, when the rotating rod 61 rotates, it drives the connecting shaft 63 to rotate, thereby causing the connecting shaft 63 to drive the crushing roller 64 to rotate on the filter screen plate 76, thereby squeezing and crushing the blocky aluminum ash accumulated on the filter screen plate 76. At the same time, when the rotating rod 61 rotates, it drives the contact mechanism 65 to rotate on the filter screen plate 76. The rotating rod 61 drives the contact rod 651 to rotate, which causes the contact rod 651 to drive the contact block 652 to contact and move with the inner wall of the tank 1. This allows the scraper 793 to scrape and clean the inner wall of the tank 1, thus preventing the powdery aluminum ash generated during the crushing of blocky aluminum ash from accumulating and remaining on the inner wall of the tank 1. At the same time, when the rotating rod 61 drives the contact rod 651 to rotate in the inner cavity of the tank 1, the round block 655 on the contact rod 651 contacts and turns the aluminum ash in the tank 1 through the connecting shaft 654, thus preventing the crushed aluminum ash from agglomerating in the inner cavity of the tank 1. When crushing the blocky aluminum ash in tank 1, the electric hydraulic rod 72 is opened, and the output end of the electric hydraulic rod 72 drives the connecting arm 73 to move back and forth. This causes the connecting arm 73 to drive the filter plate 76 to perform screening work through the sliding rod 75, thereby screening the crushed aluminum ash. At the same time, when the filter plate 76 moves back and forth in the screening shell 71, when the connecting arm 73 drives the filter plate 76 to slide upward on the fixed rod 78, the bottom of the filter plate 76 contacts the side of the crushing roller 64, which facilitates the crushing roller 64 to crush the blocky aluminum ash screened on the filter plate 76. When the connecting arm 73 drives the filter plate 76 to slide downward on the fixed rod 78, the filter plate 76 cleans the blocky removal mechanism 79 on the connecting frame 77, thereby preventing uncrushed aluminum blocks from getting stuck in the mesh of the filter plate 76 during the screening of the blocky aluminum ash. When the filter plate 76 moves downward, the mesh openings of the filter plate 76 are pressed against the top of the ejector pin 792, allowing the ejector pin 792 to push out the aluminum block stuck in the mesh openings of the filter plate 76. At the same time, the scraper 793 can scrape and clean the inner wall of the mesh openings of the filter plate 76. Square grooves 794 are evenly provided on the side of the scraper 793, so that when the scraper 793 comes into contact with the mesh openings of the filter plate 76, the aluminum dust generated during the crushing can slide out through the square grooves 794, thus avoiding interference with the normal passage of aluminum dust when cleaning the mesh openings of the filter plate 76. After being screened, the aluminum ash falls downwards. By turning on the second motor 83, the output end of the second motor 83 drives the rotating shaft 84 to rotate the rotating frame 85 in the inner cavity of the discharge shell 82. This causes the rotating frame 85 to impact and disperse the crushed aluminum ash. At the same time, the rotating frame 85 squeezes against the spraying mechanism 81, thus spraying the aluminum ash to reduce dust during discharge. The aluminum ash impacted by the rotating frame 85 contains various impurities, including various iron elements. The impact of the rotating frame 85 with the screened aluminum ash causes the screened aluminum ash to be fully dispersed. At the same time, by setting up a magnetic screen 87, the aluminum ash impacted by the rotating frame 85 falls onto the magnetic screen 87, allowing the magnetic screen 87 to adsorb the trace iron elements attached to the aluminum ash. The aluminum ash is discharged through the mesh of the magnetic screen 87, thus avoiding the residual iron impurities in the crushed aluminum ash. The rotating frame 85 rotates within the inner cavity of the discharge housing 82. As the rotating frame 85 rotates, it presses the extrusion plate 814, causing the extrusion plate 814 to move within the inner cavity of the water tank 811. This allows the water in the water tank 811 to be sprayed out through the spray head 818. Thus, during the separation and discharge of aluminum ash, the dust generated when the rotating frame 85 collides with the aluminum ash can be sprayed to reduce dust.

[0025] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
