Description

Technical Field

[0001] This invention relates to the technical field of aluminum slag and aluminum ash processing equipment, specifically to high-efficiency separation equipment for aluminum slag and aluminum ash and its usage method. Background Technology

[0002] Aluminum slag and aluminum ash separation is a process that uses specific equipment and technology to recover metallic aluminum and other valuable components from aluminum slag and aluminum ash. This process is mainly used in industries such as recycled aluminum production, electrolytic aluminum plants, aluminum profile plants, and aluminum plate plants, aiming to improve resource utilization efficiency and meet environmental protection requirements. Rotary drum screens are often used in aluminum slag and aluminum ash separation.

[0003] Existing rotary drum screens have the following technical problems when separating aluminum slag and aluminum ash:

[0004] 1. When the rotary drum screen can separate aluminum slag and aluminum ash, it can rotate and separate them. However, when there is too much aluminum slag and aluminum ash, they tend to accumulate together, which affects the separation effect of aluminum ash falling and causing a large amount of aluminum ash to stick to the separated aluminum slag, thus affecting the separation effect of aluminum slag and aluminum ash.

[0005] 2. When the rotary drum screen separates aluminum slag and aluminum ash, the aluminum ash will float out of the slag outlet of the rotary drum screen and stick to the aluminum slag after screening, thus affecting the separation effect of aluminum slag and aluminum ash. Summary of the Invention

[0006] The purpose of this invention is to solve the above problems by providing an efficient aluminum slag and aluminum ash separation device and its usage method.

[0007] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0008] A high-efficiency aluminum slag and aluminum ash separation device includes a casing. Two ends of the casing's side are fixed with first drive motors. The other end of the output shaft of the first drive motors is fixedly connected to a first drive wheel located inside the casing. The outer surface of the first drive wheel is connected to a first drum screen fitted inside the casing. A collection box is placed in the middle of the casing, below the first drum screen. A slag collection box is placed on the left side of the casing. A fan is fixed above the slag collection box on the side of the casing. An air jet pipe is fixedly connected to the fan, with the other end of the air jet pipe extending into the slag discharge end of the first drum screen. A fixing plate is fixed inside the casing. An electric telescopic rod located inside the first drum screen is fixed to the fixing plate. A sloped baffle is fixed to the lower end of the electric telescopic rod. A vertical rod is fixed to the sloped baffle, with its upper end penetrating the fixing plate. A smoke detector is fixed to the bottom of the fixing plate. An exhaust pipe located on the left side of the slag collection box is threaded into the inside of the casing. A ash collection bag is fixed to the other end of the exhaust pipe. A controller electrically connected to the smoke detector is fixed to the casing.

[0009] Furthermore, a second drive motor is fixed to the top of the fixed plate. The second drive motor is electrically connected to a pressure control component. The other end of the output shaft of the second drive motor is driven to a second drive wheel sleeved inside the fixed plate. A limiting wheel sleeved inside the fixed plate is driven to the outer surface of the second drive wheel. A brush block that adheres to the outer surface of the smoke detector is fixed to the lower end of the limiting wheel.

[0010] Furthermore, the pressure control component includes a slot, which is opened inside the fixed plate. A convex block is movably fitted inside the slot. An inclined extrusion block is fixed to the top of the convex block, and a rigid spring is fixed to the side of the convex block. The other end of the rigid spring is fixedly connected to the inner wall of the slot. An inclined push block fixed to a vertical rod is connected to the inclined surface of the inclined extrusion block. A pressure switch fixed to the fixed plate is extruded and connected to the side of the inclined extrusion block. The pressure switch is electrically connected to the second drive motor and the controller, respectively.

[0011] Furthermore, a feed pipe is fixedly connected to the left side of the housing, and a top cover is threaded onto the upper end of the feed pipe.

[0012] Furthermore, a first hollow hinge block is hinged to the left end of the first drum screen, a connecting block is movably sleeved inside the first hollow hinge block, a second hollow hinge block is movably sleeved at the other end of the connecting block, a second drum screen is hinged to the second hollow hinge block and sleeved inside the first drum screen, and a hydraulic assembly is fixedly connected to the first hollow hinge block and the second hollow hinge block.

[0013] Furthermore, the hydraulic assembly includes a hydraulic conveyor fixed to the housing, with a first connecting pipe and a second connecting pipe fixedly connected to the hydraulic conveyor. The other end of the first connecting pipe is connected to a first annular groove block sleeved inside the housing, and the first annular groove block is fixedly connected to a second hollow hinge block. The other end of the second connecting pipe is connected to a second annular groove block sleeved inside the housing, and the second annular groove block is fixedly connected to the first hollow hinge block.

[0014] Furthermore, a water tank is placed on the side of the housing, and a hose is threaded onto the other end of the exhaust pipe, with the other end of the hose extending into the water tank.

[0015] The operating method of the high-efficiency aluminum slag and aluminum ash separation equipment includes the following steps:

[0016] S1. Open the feed pipe by rotating the top cover and pour the aluminum slag and aluminum ash into the second drum screen for screening. Start the first drive motor to make the first drive wheel drive the first drum screen and the second drum screen to rotate and screen the aluminum slag and aluminum ash.

[0017] S2. Then, by starting the blower, the jet pipe blows the aluminum ash adhering to the aluminum slag and the aluminum ash that drifts to the slag collection box back into the first drum screen, so that the gas inside the first drum screen will be discharged from the exhaust pipe, and the ash collection bag will filter the dust in the gas.

[0018] S3. Subsequently, the aluminum ash is blown towards the smoke detector through the inclined surface of the inclined baffle. The smoke detector detects the aluminum ash and controls the electric telescopic rod through the controller, so that the electric telescopic rod drives the inclined baffle to partially block the aluminum slag and aluminum ash inside the first drum screen.

[0019] S4. When the smoke detector does not detect aluminum ash, the electric telescopic rod drives the inclined baffle to move upward to remove the obstruction of large pieces of aluminum slag inside the first drum screen, so that the large pieces of aluminum slag can be screened into the slag collection box, while the aluminum ash is screened into the return collection box.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. This invention activates a blower, causing the jet pipe to blow aluminum ash adhering to the aluminum slag inside the second drum screen and aluminum ash drifting towards the slag collection box back into the first drum screen. The aluminum ash is then blown towards the smoke detector through an inclined baffle. The smoke detector detects the aluminum ash and, via a controller, controls an electric telescopic rod. This electric telescopic rod drives the inclined baffle to partially block the aluminum slag and ash inside the second drum screen, thus preventing the aluminum slag and ash from accumulating and affecting the falling and screening of the aluminum ash, achieving a more thorough separation of aluminum slag and ash.

[0022] 2. This invention uses a vertical rod to drive an inclined pushing block to move and squeeze the inclined squeezing block, which in turn squeezes the pressure switch. The pressure switch then transmits the squeezing data to the controller, which in turn activates the second drive motor based on the dust concentration inside the first drum screen. This causes the second drive wheel to rotate along the inside of the fixed plate, which in turn causes the limit wheel to drive the brush block to clean the dust from the smoke detector, preventing dust from sticking to the smoke detector and affecting the dust detection effect.

[0023] 3. This invention activates the hydraulic conveyor, causing the first connecting pipe and the second connecting pipe to respectively introduce hydraulic oil into the first annular groove block and the second annular groove block. This allows the hydraulic oil to enter the interior of the second hollow hinge block and the first hollow hinge block. The first hollow hinge block can then rotate the second drum screen by pushing the connecting block and the second hollow hinge block until the holes of the second drum screen and the first drum screen no longer align. At this point, because the interior of the second drum screen is sealed, the blower can quickly expel the aluminum ash inside the casing through the jet pipe to the exhaust pipe, thus achieving the purpose of rapid aluminum ash discharge and improving the efficiency of the device in screening aluminum ash and slag.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] Example 1, as Figure 1-10 As shown, the high-efficiency aluminum slag and aluminum ash separation equipment includes a casing 1. A first drive motor 2 is fixed to both ends of the side of the casing 1. The other end of the output shaft of the first drive motor 2 is fixedly connected to a first drive wheel 3 located inside the casing 1. A first drum screen 4, sleeved inside the casing 1, is connected to the outer surface of the first drive wheel 3. A collection box 8 is placed in the middle of the casing 1, below the first drum screen 4. A slag collection box 7 is placed on the left side of the casing 1. A blower 9 is fixed to the side of the casing 1, above the slag collection box 7. An air jet pipe 10 is fixedly connected to the blower 9, and the other end of the air jet pipe 10 extends... Inside the slag discharge end of the first drum screen 4, a fixing plate 13 is fixed inside the casing 1. An electric telescopic rod 14 located inside the first drum screen 4 is fixed on the fixing plate 13. An inclined baffle 15 is fixed to the lower end of the electric telescopic rod 14. A vertical rod 16 is fixed on the inclined baffle 15. The upper end of the vertical rod 16 passes through the fixing plate 13. A smoke detector 17 is fixed to the bottom of the fixing plate 13. An exhaust pipe 11 located on the left side of the slag collection box 7 is threaded inside the casing 1. A dust collection bag 12 is fixed to the other end of the exhaust pipe 11. A controller 3 electrically connected to the smoke detector 17 is fixed on the casing 1. 9. By starting the first drive motor 2 and the fan 9, the first drive wheel 3 drives the first drum screen 4 to rotate and screen the aluminum slag and aluminum dust. At the same time, by starting the fan 9, the jet pipe 10 blows the aluminum dust adhering to the aluminum slag inside the second drum screen 31 and the aluminum dust drifting towards the slag collection box 7 back into the first drum screen 4. Then, the aluminum dust is blown towards the smoke detector 17 through the inclined surface of the inclined baffle 15. The smoke detector 17 detects the aluminum dust and controls the electric telescopic rod 14 through the controller 39, so that the electric telescopic rod 14 drives the inclined baffle 15 to screen the aluminum slag inside the first drum screen 4. The aluminum slag and ash are partially blocked to prevent them from accumulating and affecting the falling and screening of aluminum ash. After the large amount of aluminum slag and ash is blocked, only a small amount of aluminum slag and ash will move towards the blower 9. The blower 9 can better blow the aluminum ash adhering to the aluminum slag into the first drum screen 4 through the jet pipe 10. When the smoke detector 17 does not detect aluminum ash, the electric telescopic rod 14 drives the inclined baffle 15 to move upward to remove the blockage of large pieces of aluminum slag inside the first drum screen 4, so that the large pieces of aluminum slag can be screened into the slag collection box 7, while the aluminum ash is screened into the return collection box 8.

[0037] Example 2, as Figure 1-8As shown, based on the above embodiment, a second drive motor 18 is fixed to the top of the fixed plate 13. The second drive motor 18 is electrically connected to a pressure control component. The other end of the output shaft of the second drive motor 18 is connected to a second drive wheel 19 sleeved inside the fixed plate 13. A limiting wheel 20 sleeved inside the fixed plate 13 is connected to the outer surface of the second drive wheel 19. A brush block 21 attached to the outer surface of the smoke detector 17 is fixed to the lower end of the limiting wheel 20. By starting the second drive motor 18, the second drive wheel 19 will drive the limiting wheel 20 to rotate along the inside of the fixed plate 13, thereby causing the limiting wheel 20 to drive the brush block 21 to clean the dust from the smoke detector 17, preventing dust from sticking to the smoke detector 17 and affecting the dust detection effect.

[0038] The pressure control assembly includes a slot 22, which is formed inside the fixed plate 13. A convex block 23 is movably fitted inside the slot 22. A sloping extrusion block 24 is fixed to the top of the convex block 23, and a rigid spring 27 is fixed to the side of the convex block 23. The other end of the rigid spring 27 is fixedly connected to the inner wall of the slot 22. A sloping push block 25 fixed to the vertical rod 16 is connected to the sloping surface of the sloping extrusion block 24. A pressure switch 26 fixed to the fixed plate 13 is pressed and connected to the side of the sloping extrusion block 24. The pressure switch 26 is electrically connected to the second drive motor 18 and the controller 39, respectively. Through the design of the sloping extrusion block 24 and the pressure switch 26... This allows the inclined baffle 15 to move and press the inclined pressing block 24 via the vertical rod 16, thereby causing the inclined pressing block 24 to press the pressure switch 26. The pressure switch 26 then transmits the pressing data to the controller 39. Since the moving height of the inclined baffle 15 is determined by the dust concentration detected by the smoke detector 17, the controller 39 can start and stop the second drive motor 18 based on the dust concentration inside the first drum screen 4. This allows the brush block 21 to determine the cleaning time based on the dust concentration inside the first drum screen 4, effectively preventing dust from sticking to the smoke detector 17 and affecting the dust detection effect.

[0039] Example 2, as Figure 1-10 As shown, based on the above embodiment, a feed pipe 5 is fixedly connected to the left side of the casing 1. A cover 6 is threaded onto the upper end of the feed pipe 5. By rotating the cover 6, the feed pipe 5 can be opened, allowing the operator to pour aluminum slag and aluminum ash into the first drum screen 4 for screening. Then, the cover 6 is rotated onto the feed pipe 5 to prevent dust inside the casing 1 from being discharged from the feed pipe 5.

[0040] A first hollow hinge block 28 is hinged to the left end of the first drum screen 4. A connecting block 29 is movably sleeved inside the first hollow hinge block 28. A second hollow hinge block 30 is movably sleeved at the other end of the connecting block 29. A second drum screen 31, which is sleeved inside the first drum screen 4, is hinged to the second hollow hinge block 30. A hydraulic assembly is fixedly connected to the first hollow hinge block 28 and the second hollow hinge block 30. Through the design of the first hollow hinge block 28, the second hollow hinge block 30, and the connecting block 29, when the first drum screen 4 rotates, the first hollow hinge block 28 will drive the second drum screen 31 to rotate synchronously through the connecting block 29 and the second hollow hinge block 30.

[0041] The hydraulic assembly includes a hydraulic transmitter 34 fixed to the housing 1. A first connecting pipe 35 and a second connecting pipe 36 are fixedly connected to the hydraulic transmitter 34. The other end of the first connecting pipe 35 is connected to a first annular groove block 32 fitted inside the housing 1. The first annular groove block 32 is fixedly connected to a second hollow hinge block 30. The other end of the second connecting pipe 36 is connected to a second annular groove block 33 fitted inside the housing 1. The second annular groove block 33 is fixedly connected to a first hollow hinge block 28. By activating the hydraulic transmitter 34, the hydraulic system will... The first connecting pipe 35 and the second connecting pipe 36 respectively introduce hydraulic oil into the first annular groove block 32 and the second annular groove block 33, thereby allowing the hydraulic oil to enter the interior of the second hollow hinge block 30 and the first hollow hinge block 28. This allows the first hollow hinge block 28 to rotate the second drum screen 31 by pushing the connecting block 29 and the second hollow hinge block 30 until the holes of the second drum screen 31 and the first drum screen 4 no longer correspond. At this point, the gas and dust inside the first drum screen 4 will be blown by the jet pipe 10 to the exhaust pipe 11 and quickly discharged.

[0042] A water tank 38 is placed on the side of the casing 1. A hose 37 is threaded onto the other end of the exhaust pipe 11. The other end of the hose 37 extends into the water tank 38. Through the design of the hose 37 and the water tank 38, the dust discharged from the exhaust pipe 11 can be discharged into the water tank 38 through the hose 37, thereby allowing the water inside the water tank 38 to better filter and adsorb impurities in the gas.

[0043] The operating method of the high-efficiency aluminum slag and aluminum ash separation equipment includes the following steps:

[0044] S1. Open the feed pipe 5 by rotating the top cover 6, and pour the aluminum slag and aluminum ash into the second drum screen 31 for screening. Start the first drive motor 2, so that the first drive wheel 3 drives the first drum screen 4 and the second drum screen 31 to rotate and screen the aluminum slag and aluminum ash.

[0045] S2. Then, by starting the blower 9, the jet pipe 10 blows the aluminum ash adhering to the aluminum slag and the aluminum ash drifting to the slag collection box 7 back into the first drum screen 4, so that the gas inside the first drum screen 4 will be discharged from the exhaust pipe 11, and the dust collection bag 12 will filter the dust in the gas.

[0046] S3. Subsequently, the aluminum ash is blown towards the smoke detector 17 through the inclined surface of the inclined baffle 15. The smoke detector 17 detects the aluminum ash and controls the electric telescopic rod 14 through the controller 39, thereby causing the electric telescopic rod 14 to drive the inclined baffle 15 to partially block the aluminum slag and aluminum ash inside the first drum screen 4.

[0047] S4. When the smoke detector 17 does not detect aluminum ash, the electric telescopic rod 14 drives the inclined baffle 15 to move upward to remove the obstruction of large aluminum slag inside the first drum screen 4, so that the large aluminum slag can be screened into the slag collection box 7, while the aluminum ash is screened into the return collection box 8.

[0048] In practical use, this invention, as a high-efficiency aluminum slag and aluminum ash separation device and its usage method, firstly, by rotating the upper cover 6 to open the feed pipe 5, the operator can pour the aluminum slag and aluminum ash into the second drum screen 31 for sieving. By starting the first drive motor 2, the first drive wheel 3 drives the first drum screen 4 to rotate, which in turn causes the first hollow hinge block 28 to drive the second drum screen 31 to rotate synchronously through the connecting block 29 and the second hollow hinge block 30, thus sieving the aluminum slag and aluminum ash. At this time, the aluminum ash floating during sieving will be detected by the smoke detector 17, and the detection data will be transmitted to the controller 39. Then, the controller 39 can control the electric telescopic rod 14 based on the aluminum ash concentration detected by the smoke detector 17. The electric telescopic rod 14 moves the inclined baffle 15 downward to partially block the aluminum slag and aluminum dust inside the second drum screen 31, thus preventing the aluminum slag and aluminum dust from accumulating together and affecting the falling and screening of aluminum dust. Then, by starting the blower 9, the jet pipe 10 blows the aluminum dust adhering to the aluminum slag and the aluminum dust drifting towards the slag collection box 7 back into the first drum screen 4. The aluminum dust is then blown towards the smoke detector 17 through the inclined baffle 15, thus preventing the aluminum dust from falling into the slag collection box 7. The aluminum slag is then screened into the slag collection box 7, while the aluminum dust is screened into the return collection box 8. The gas inside the first drum screen 4 will then be discharged from the exhaust pipe 11. At this time, the dust collection bag 12 will filter the dust in the gas. This design achieves the purpose of more complete separation of aluminum slag and aluminum dust.

[0049] Simultaneously, the inclined baffle 15 will move and squeeze the inclined pushing block 25 via the vertical rod 16, thereby squeezing the inclined squeezing block 24. This will cause the inclined squeezing block 24 to squeeze the pressure switch 26, which will then transmit the squeezing data to the controller 39. Since the moving height of the inclined baffle 15 is determined by the dust concentration detected by the smoke detector 17, the controller 39 will start the second drive motor 18 based on the dust concentration inside the first drum screen 4. This will cause the second drive wheel 19 to drive the limit wheel 20 to rotate along the inside of the fixed plate 13, which will then drive the brush block 21 to clean the dust from the smoke detector 17, preventing dust from sticking to the smoke detector 17 and affecting the dust detection effect.

[0050] When the smoke detector 17 fails to detect aluminum ash and it is necessary to quickly remove the floating aluminum ash inside the casing 1, the operator activates the hydraulic conveyor 34. This causes the first connecting pipe 35 and the second connecting pipe 36 to respectively introduce hydraulic oil into the first annular groove block 32 and the second annular groove block 33. The hydraulic oil then enters the second hollow hinge block 30 and the first hollow hinge block 28, allowing the first hollow hinge block 28 to rotate the second drum screen 31 by pushing the connecting block 29 and the second hollow hinge block 30, until the second drum screen 31 and the first... When the four holes of the first drum screen do not align, the process stops. At this time, the gas and dust inside the first drum screen 4 will be blown by the jet pipe 10 to the exhaust pipe 11 for rapid discharge. The dust discharged from the exhaust pipe 11 can then be discharged into the water tank 38 through the hose 37, allowing the water in the water tank 38 to better filter and adsorb impurities in the gas. The exhaust pipe 11 and hose 37 are then disassembled by rotating the exhaust pipe 11 and hose 37, and the aluminum ash filtered by the ash collection bag 12 will be poured into the collection box 8 for collection. This achieves the purpose of quickly discharging aluminum ash and improves the efficiency of the device in screening aluminum ash and aluminum slag.

Start the first drive motor (2) so that the first drive wheel (3) drives the first drum screen (4) and the second drum screen (31) to rotate and screen the aluminum slag and aluminum ash. S2. Then, by starting the blower (9), the jet pipe (10) blows the aluminum ash adhering to the aluminum slag and the aluminum ash that drifts to the slag collection box (7) back into the first drum screen (4), so that the gas inside the first drum screen (4) will be discharged from the exhaust pipe (11), and the dust collection bag (12) will filter the dust in the gas. S3. Subsequently, aluminum ash is blown towards the smoke detector (17) through the inclined surface of the inclined baffle (15). The smoke detector (17) detects the aluminum ash and controls the electric telescopic rod (14) through the controller (39), thereby causing the electric telescopic rod (14) to drive the inclined baffle (15) to partially block the aluminum slag and aluminum ash inside the first drum screen (4). S4. When the smoke detector (17) does not detect aluminum ash, the electric telescopic rod (14) drives the inclined baffle (15) to move upward to remove the blockage of large aluminum slag inside the first drum screen (4), so that the large aluminum slag can be screened into the slag collection box (7), while the aluminum ash is screened into the return collection box (8).
