Description

Technical Field

[0001] This application relates to the field of aluminum ash processing technology, and in particular to an aluminum ash sorting and pneumatic conveying device. Background Technology

[0002] Aluminum ash is a byproduct of aluminum smelting and processing. It contains a large amount of recyclable aluminum, so it is necessary to sort and recycle the aluminum in the aluminum ash for reuse.

[0003] One related method for aluminum ash recycling is the vibration sorting method. When aluminum ash needs to be sorted and recycled, a vibrating screen is used to separate the metallic aluminum from impurities in the aluminum ash. After the aluminum metal is separated, it is moved to the next processing stage by a conveyor belt.

[0004] When aluminum powder is sorted and processed using the above method, the aluminum metal is separated out. During the movement of the conveyor belt, the aluminum metal is not only easy to fall off the belt, but the efficiency of the belt in conveying aluminum metal is also low, resulting in low aluminum metal processing efficiency. Utility Model Content

[0005] To improve the efficiency of aluminum ash processing, this application provides an aluminum ash sorting and pneumatic conveying device.

[0006] This application provides an aluminum ash sorting and pneumatic conveying device, which adopts the following technical solution: An aluminum ash sorting pneumatic conveying device includes: A hammer mill, which is fixedly installed on the ground, can crush large particles of impurities in aluminum ash into fine particles; A conveyor belt is fixedly installed directly below the hammer mill; A screening component is fixedly installed on the ground and is at the same horizontal level as the hammer mill. The screening component can separate aluminum metal from impurities in aluminum powder. A pneumatic conveyor is fixedly installed on the ground and located directly below the screening component. The pneumatic conveyor can transport the separated aluminum metal to the next processing stage.

[0007] By adopting the above technical solution, when aluminum ash needs to be sorted, the aluminum ash is poured into a hammer mill and the hammer mill is started. After the hammer mill starts, the large particles of impurities in the aluminum ash are crushed into fine particles. After crushing, the aluminum ash falls onto the conveyor belt under its own gravity. After the aluminum ash falls onto the conveyor belt, the conveyor belt is started. After the conveyor belt starts, it moves the aluminum ash to the screening unit. After the aluminum ash moves to the screening unit, the screening unit is started. After the screening unit starts, the aluminum metal in the aluminum ash is separated from the impurities, and the separated aluminum metal enters the pneumatic conveyor. After the aluminum metal enters the pneumatic conveyor, the pneumatic conveyor is started. After the pneumatic conveyor starts, the aluminum powder is quickly conveyed to the next processing stage by high-pressure airflow, thereby effectively improving the conveying efficiency of aluminum metal and thus improving the efficiency of aluminum ash sorting.

[0008] Optionally, the screening element includes: The fixing frame is fixedly installed on the ground; Mounting bracket, the mounting bracket being fixedly mounted on the fixed bracket; A vibration chamber, which is slidably mounted on the mounting frame, has a vertically arranged vibration cavity inside. A vibration motor is fixedly mounted on the side wall of the vibration chamber; The first sieve plate is fixedly disposed inside the vibration chamber; The second sieve plate is fixedly disposed inside the vibration chamber and is located directly below the first sieve plate. The first discharge port is fixedly installed on the side wall of the vibrating chamber away from the conveyor belt, and the first discharge port is at the same horizontal line as the first screen plate. The second discharge port is fixedly installed on the side wall of the vibrating chamber away from the conveyor belt, and the second discharge port is at the same horizontal line as the second screen plate.

[0009] By adopting the above technical solution, when the crushed aluminum powder falls onto the conveyor belt, the conveyor belt is activated. Once activated, the conveyor belt moves the aluminum powder into the vibrating chamber. After the aluminum powder enters the vibrating chamber, the vibrating motor is activated, causing the vibrating chamber to vibrate vertically. The vibration of the vibrating chamber then causes the first and second sieve plates to vibrate synchronously. Because aluminum particles are relatively large while impurities are relatively small, the aluminum particles are blocked by the first sieve plate and cannot fall onto the second sieve plate, while the smaller impurity particles pass through the first sieve plate smoothly and fall onto the second sieve plate. After the aluminum and impurities are separated, the continuous vibration of the vibrating chamber causes the aluminum to gradually move towards the first discharge port and be discharged, while the impurity particles gather towards the second discharge port and are discharged. By screening aluminum powder in this way, the aluminum and impurities within the aluminum powder are separated, thereby effectively improving the purity of the separated aluminum.

[0010] Optionally, the air pressure transmission component includes: A storage bin, which is fixedly installed on the ground and is connected to the first discharge port; A conveying pipe, one end of which is fixedly connected to the discharge port at the bottom of the storage silo; A cyclone separator, wherein the cyclone separator is fixedly connected to the end of the conveying pipe away from the storage silo; The Roots blower is fixedly installed at the top of the cyclone separator; An exhaust pipe is fixedly connected to the outlet end of the Roots blower.

[0011] By adopting the above technical solution, aluminum metal, after being discharged from the first outlet, falls into the storage silo under its own gravity. Once the aluminum metal enters the storage silo, the Roots blower is activated. The activation of the Roots blower creates negative pressure in the conveying pipe. Since the conveying pipe is connected to the storage silo, the aluminum metal falling into the storage silo is drawn into the cyclone separator under the negative pressure. After entering the cyclone separator, the aluminum metal is thrown against the inner wall of the cyclone separator under centrifugal force and gradually deposits at the bottom of the cyclone separator. The aluminum metal deposited at the bottom of the cyclone separator is discharged through the discharge port at the bottom of the cyclone separator to the next process. By conveying aluminum metal particles in this way, the screened aluminum metal can be quickly transported to the next process under negative pressure, thereby effectively improving the efficiency of aluminum metal particle conveying.

[0012] Optionally, a discharge valve is fixedly installed at the bottom of the storage silo.

[0013] By adopting the above technical solution, the discharge valve is designed so that aluminum metal can be discharged uniformly after accumulating a certain volume in the storage bin. This avoids the rate at which aluminum metal is adsorbed by the Roots blower being greater than the rate at which aluminum metal falls into the storage bin, thereby preventing the interruption of aluminum metal transmission and effectively improving the stability of aluminum metal transmission.

[0014] Optionally, a spring support column is fixedly installed on the mounting frame, one end of the spring support column is fixedly connected to the mounting frame, and the other end of the spring support column is fixedly connected to the side wall of the vibration chamber.

[0015] By adopting the above technical solution, the spring support column can buffer the impact force between the vibration chamber and the mounting frame during vibration, avoiding damage to the vibration chamber caused by excessive impact force between the vibration chamber and the mounting frame, thereby effectively extending the service life of the vibration chamber.

[0016] Optionally, four spring support columns are spaced apart along the mounting frame.

[0017] By adopting the above technical solution, the setting of four spring support columns can avoid the vibration chamber from tilting during vibration due to single-point support, thereby effectively improving the stability of the vibration chamber during vibration.

[0018] Optionally, a protective cover is fixedly installed on the top of the vibration chamber.

[0019] By adopting the above technical solution, the protective cover can ensure that the dust and impurities in the aluminum powder will not diffuse into the air during the vibration separation process of the vibrating chamber, thus avoiding the situation where the impurities in the aluminum powder cannot be collected and processed, thereby effectively improving the stability of aluminum powder screening.

[0020] Optionally, a waste collection bin is fixedly provided at the bottom of the second discharge port, and the waste collection bin is connected to the second discharge port.

[0021] By adopting the above technical solution, impurities in the waste collection bin can fall into the waste collection bin under their own gravity when passing through the second discharge port, thereby effectively improving the convenience of collecting impurity particles.

[0022] In summary, this utility model provides an aluminum ash sorting pneumatic conveying device, which has at least one of the following beneficial technical effects: 1. When aluminum ash needs to be sorted, the aluminum ash is poured into the hammer mill and the hammer mill is started. After the hammer mill starts, the large particles of impurities in the aluminum ash will be crushed into fine particles. After crushing, the aluminum ash falls onto the conveyor belt under its own gravity. After the aluminum ash falls onto the conveyor belt, the conveyor belt is started. After the conveyor belt starts, it moves the aluminum ash to the screening unit. After the aluminum ash moves to the screening unit, the screening unit is started. After the screening unit starts, it can separate the aluminum metal from the impurities in the aluminum ash and let the separated aluminum metal enter the pneumatic conveyor. After the aluminum metal enters the pneumatic conveyor, the pneumatic conveyor is started. After the pneumatic conveyor starts, the aluminum powder can be quickly conveyed to the next processing stage by high-pressure airflow, thereby effectively improving the conveying efficiency of aluminum metal and thus improving the efficiency of aluminum ash sorting.

[0023] 2. Once the pulverized aluminum powder falls onto the conveyor belt, the conveyor belt is activated. This activates the conveyor belt, which moves the aluminum powder into the vibrating chamber. After the aluminum powder enters the vibrating chamber, the vibration motor is started, causing the vibrating chamber to vibrate vertically. The vibration of the chamber then causes the first and second sieve plates to vibrate synchronously. Because aluminum particles are relatively large while impurities are relatively small, the aluminum particles are blocked by the first sieve plate and cannot fall onto the second sieve plate. However, the smaller impurity particles pass through the first sieve plate and fall onto the second sieve plate. After the aluminum and impurities are separated, the continuous vibration of the vibrating chamber causes the aluminum to gradually move towards the first discharge port and be discharged, while the impurity particles gather towards the second discharge port and are discharged. By screening the aluminum powder in this way, the aluminum and impurities within the powder are separated, effectively improving the purity of the separated aluminum.

[0024] 3. After being discharged from the first outlet, the aluminum falls into the storage silo under its own gravity. Once the aluminum enters the silo, the Roots blower is activated. The blower creates negative pressure in the conveying pipe, and because the conveying pipe is connected to the storage silo, the aluminum falling into the silo is drawn into the cyclone separator under this negative pressure. After entering the cyclone separator, the aluminum is thrown against the inner wall of the separator by centrifugal force and gradually settles at the bottom. The aluminum settled at the bottom of the cyclone separator is discharged through the discharge port at the bottom of the separator to the next process. This method of transferring aluminum particles allows for rapid transport of the screened aluminum to the next process under negative pressure, effectively improving the efficiency of aluminum particle transfer.

[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0028] Combination Figure 1 , Figure 2 and Figure 4 This application discloses an aluminum ash sorting pneumatic conveying device, including a hammer mill 1, a conveyor belt 11, a screening component 2, and a pneumatic conveyor 3.

[0030] In practical use, when aluminum powder needs to be sorted and conveyed, the aluminum powder is poured into the hammer mill 1 and started.

The first discharge port 28 and the first screen plate 26 are on the same horizontal line. The second discharge port 29 is fixedly installed on the side wall of the vibrating chamber 23 away from the conveyor belt 11.

The storage silo 31 is fixedly installed on the ground and is connected to the first discharge port 28. One end of the conveying pipe 32 is fixedly connected to the discharge port at the bottom of the storage silo 31. The cyclone separator 33 is fixedly connected to the end of the conveying pipe 32 away from the storage silo 31. The Roots blower 34 is fixedly installed at the top of the cyclone separator 33, and the exhaust pipe 35 is fixedly connected to the air outlet of the Roots blower 34.

A waste collection silo 6 is fixedly installed at the bottom of the second discharge port 29 and is connected to the second discharge port 29.

[0032] In this embodiment, the fixing frame 21 is fixedly installed on the ground by bolt connection. The mounting frame 22 can be fixedly connected to the fixing frame 21 by integral molding or by welding; no specific limitation is made in this embodiment.

[0033] In practical use, when aluminum ash needs to be sorted and conveyed, the aluminum ash is poured into the hammer mill 1 and the hammer mill 1 is started. After the hammer mill 1 is started, the aluminum ash is crushed into fine particles. After being crushed into particles, the aluminum ash falls onto the conveyor belt 11 under its own gravity. After the aluminum ash falls onto the conveyor belt 11, the conveyor belt 11 is started. After the conveyor belt 11 is started, it carries the aluminum ash into the vibrating chamber 23 until the aluminum ash falls onto the first screen plate 26. After aluminum ash falls into the vibrating chamber 23, the vibrating motor 25 is started. After the vibrating motor 25 starts, it drives the vibrating chamber 23 to start vibrating. After the vibrating chamber 23 vibrates, it drives the first screen plate 26 and the second screen plate 27 to vibrate synchronously. After the first screen plate 26 vibrates, it drives the aluminum ash particles to start vibrating synchronously. Since the aluminum ash contains aluminum metal particles and impurity particles, and since the size of the aluminum metal particles is larger than the size of the impurity particles, after vibration, the impurity particles can pass through the screen holes of the first screen plate 26 and fall onto the second screen plate 27, while the aluminum metal particles remain on the first screen plate 26. With the continuous vibration of the vibrating chamber 23, the particles move towards the first screen plate 26 and fall into the storage bin 31 through the first discharge port 28, while the impurity particles fall into the waste collection bin 6 through the second discharge port 29. After aluminum particles fall into the storage silo 31, the discharge valve 4 is opened and the Roots blower 34 is started. Once started, the Roots blower 34 draws the aluminum particles falling into the conveying pipe 32 into the cyclone separator 33. After entering the cyclone separator 33, the aluminum particles are thrown against the inner wall of the cyclone separator under centrifugal force and discharged through the discharge port of the cyclone separator 33 to the next processing step. During the vibration of the vibrating chamber 23, the protective cover 7 ensures that impurities in the aluminum ash do not disperse into the air.

[0034] Combination Figure 2 In a specific embodiment, a spring support column 5 is fixedly installed on the mounting frame 22. One end of the spring support column 5 is fixedly connected to the mounting frame 22, and the other end of the spring support column 5 is fixedly connected to the side wall of the vibration chamber 23. Four spring support columns 5 are arranged at intervals along the mounting frame 22.

[0035] In this embodiment, the spring support column 5 can be fixedly connected to the mounting frame 22 and the vibration chamber 23 by integral molding or by welding. No specific limitation is made in this embodiment.

[0036] In practical use, during the vibration of the vibration chamber 23, the arrangement of multiple spring support columns 5 can prevent the vibration chamber 23 from impacting the mounting frame 22 with excessive force during vibration, thereby preventing damage to the vibration chamber 23.

[0037] The principle of this embodiment is as follows: When aluminum powder needs to be sorted and conveyed, the aluminum powder is poured into the hammer mill 1 and the hammer mill 1 is started. After the hammer mill 1 starts, the large particles of impurities in the aluminum powder are crushed into fine particles. After the aluminum powder is crushed, it falls onto the conveyor belt 11. The conveyor belt 11 is started, and after the conveyor belt 11 starts, it moves the aluminum powder towards the screening component 2 until the aluminum powder is moved into the screening component 2 by the conveyor belt 11. After the aluminum powder enters the screening component 2, the screening component 2 is started. After the screening component 2 starts, the aluminum metal in the aluminum powder can be separated from the impurities. The separated aluminum metal falls into the pneumatic conveyor 3 under its own gravity. After the aluminum metal enters the pneumatic conveyor 3, the pneumatic conveyor 3 can be started. After the pneumatic conveyor 3 starts, the separated aluminum metal can be conveyed to the next processing step.
