Abstract
Description
Technical Field
[0001] This application belongs to the field of electrolytic aluminum technology, specifically relating to an alumina conveying system and conveying method. Background Technology
[0002] In the electrolytic aluminum production process, the transportation of alumina (including fresh alumina and fluorinated alumina) is a crucial link in ensuring the continuous and stable operation of the electrolytic cell. Currently, the industry generally adopts a transportation mode that combines traditional dense-phase transportation, dilute-phase transportation, and pneumatic lifting systems. The specific process is as follows: after fresh alumina powder is unpacked and unloaded in the raw material warehouse, it is transported to the fresh alumina silo in the electrolysis workshop through a dense-phase transportation pipeline; fluorinated alumina is first collected in a temporary storage area, and then transported to the fluorinated alumina silo in the conveying pipeline by a pneumatic lifting device, and finally fed to the electrolytic cell as needed.
[0003] However, this traditional conveying system has significant drawbacks in practical applications: First, the conveying process is cumbersome and the conveying distance is long. From the raw material warehouse to the electrolytic cell, multiple pipeline transfers and material transfers are required, which not only increases the complexity of system operation but also increases the risk of material blockage and leakage. Second, the energy consumption is high. Dense phase conveying and pneumatic lifting both require high-power fans to provide high-pressure air sources. Especially in long-distance conveying scenarios, the air source equipment operates at full load for a long time, resulting in high energy consumption. Third, the conveying efficiency is low and the alumina particles are severely damaged. When the high-pressure airflow is conveyed at high speed in the pipeline, the alumina particles collide and rub violently with the inner wall of the pipeline and between the particles, causing some alumina particles to break into fine powder. This reduces the effective utilization rate of alumina and easily causes wear on the inner wall of the pipeline and blockage of the subsequent exhaust system. Summary of the Invention

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0022] See also Figure 1-2 As shown, according to an embodiment of this application, an alumina conveying system includes: The storage compartment includes a first storage compartment 1 and a second storage compartment 2. The first storage compartment 1 is disposed above the second storage compartment 2. A first feeding component 3 is disposed on the top of the first storage compartment 1, and a second feeding component 4 is disposed on the top of the second storage compartment 2. Bucket elevator 5, the bucket elevator 5 is arranged on one side of the storage bin, the bottom side of the bucket elevator 5 is provided with a storage bucket 6, and the top side of the bucket elevator 5 is provided with a discharge port 7; The discharge pipe 8 is disposed on the discharge port 7. The discharge pipe 8 is equipped with a switch 9, which can control the material discharged from the discharge port 7 to be fed into the first feeding component 3 or the second feeding component 4.
[0023] The alumina conveying system provided in this embodiment includes a storage bin, a bucket elevator 5, and a discharge pipe 8. The storage bin is divided into a first storage bin 1 and a second storage bin 2, which are arranged vertically. The first storage bin 1 is a fluorine-loaded bin for storing fluorine-loaded alumina material, and the second storage bin 2 is a fresh bin for storing fresh alumina material. The first storage bin 1 is equipped with a first feeding component 3 at its top, and the second storage bin 2 is equipped with a second feeding component 4 at its top. The first feeding component 3 and the second feeding component 4 are used to feed the fluorine-loaded alumina material and the fresh alumina material into the first storage bin 1 and the second storage bin 2, respectively. The bucket elevator 5 is located on one side of the storage bin, with a storage bin 6 on its bottom side and a discharge port 7 on its top side. The storage bin 6 is used to store material, and the bucket elevator 5 can lift the material in the storage bin 6 and feed it into the first feeding component 3 and the second feeding component 4 through the discharge pipe 8 according to the type of material. A switcher 9 is provided in the discharge pipe 8, which can control the material to be fed into the corresponding storage bin according to the type of material. In use, when conveying both fresh alumina and fluorinated alumina in the electrolytic aluminum industry, the materials to be conveyed can first be temporarily stored in the storage hopper 6, and then lifted to the top discharge port 7 by the bucket elevator 5. Subsequently, depending on the type of material, the material flow direction of the discharge pipe 8 is adjusted by the switch 9. If it is fresh alumina, the switch 9 is controlled to make the material flow into the second feeding component 4 through the discharge pipe 8, and then sent into the second storage bin 2 by the second feeding component 4. If it is fluorinated alumina, the switch 9 is controlled to switch the flow direction, so that the material flows into the first feeding component 3 through the discharge pipe 8, and finally enters the first storage bin 1. Compared to the traditional conveying mode that combines dense phase conveying, dilute phase conveying, and pneumatic lifting systems, this device uses a bucket elevator 5 to lift and feed materials into the first storage bin 1 and the second storage bin 2. This process effectively reduces collisions and wear between the material and the pipe wall, significantly reduces secondary damage, improves the effective utilization rate of alumina, and effectively avoids adverse effects on electrolysis current efficiency. The bucket elevator 5 lifts and feeds materials, saving energy and improving production efficiency at the same time.
[0024] Understandably, the number of storage bins is not limited to two sets. If more types of alumina materials need to be transported, a third storage bin can be added below the second storage bin 2, and a third feeding component and a branch pipeline of the unloading pipe 8 can be added accordingly. The multi-level adjustment of the switch 9 can realize the classified transport of multiple materials.
[0025] In one feasible implementation, the discharge pipe 8 includes a first pipe, a second pipe, and a third pipe. The first end of the first pipe is connected to the discharge port 7. The first ends of the second pipe and the first ends of the third pipe are connected to the second end of the first pipe. The switch 9 is disposed inside the discharge pipe 8 and can control the flow of material in the first pipe into the second pipe or the third pipe. The second end of the second pipe is located above the first feeding assembly 3, and the second end of the third pipe is located above the second feeding assembly 4.
[0026] In this technical solution, the discharge pipe 8 is a three-way pipe, including a first pipe, a second pipe, and a third pipe. The switcher 9 is installed inside the discharge pipe 8 and can control the material in the first pipe to selectively flow into the second pipe or the third pipe. When the bucket elevator 5 lifts the material from the storage bucket 6 to the discharge port 7, the material will first enter the first pipe. At this time, the switcher 9 rotates according to the type of material to be conveyed. If the material needs to be sent into the first storage bin 1, the switcher 9 will open the channel between the first pipe and the second pipe, so that the material flows through the second pipe to the pipe opening located above the first feeding component 3, and then enters the first storage bin 1 through the first feeding component 3. If the material needs to be sent into the second storage bin 2, the switcher 9 will open the channel between the first pipe and the third pipe, so that the material flows through the third pipe to the top of the second feeding component 4, and then is sent into the second storage bin 2 by the second feeding component 4.
[0027] It is understandable that by using the discharge pipe 8 as a three-way pipe and installing the switch 9 inside the discharge pipe 8, the second and third pipes correspond to the first feeding component 3 and the second feeding component 4 respectively, ensuring that the material discharged from the second or third pipe can accurately fall into the corresponding first feeding component 3 and second feeding component 4.
[0028] Understandably, the specific installation position of the switch 9 inside the discharge pipe 8 can be flexibly set. It can be located at the connection node between the first pipe and the second and third pipes, or it can be set at the second end of the second and third pipes respectively. The flow direction can be switched by independently controlling the opening and closing of the second and third pipes, as long as the selective conveying of materials between the two branch pipes can be reliably achieved.
[0029] In one feasible implementation, the first feeding assembly 3 includes: The first distributor 31 is disposed on the top of the first storage bin 1; The first conveyor 32 is disposed between the bucket elevator 5 and the first distributor 31, and the feed end of the first conveyor 32 is located below the second end of the second pipeline, and the discharge end is connected to the first distributor 31.
[0030] In this technical solution, the first feeding assembly 3 includes a first distributor 31 and a first conveyor 32. The first conveyor 32 is located between the bucket elevator 5 and the first distributor 31, with its feed end facing directly below the second end of the second pipeline, and its discharge end connected to the first distributor 31. This allows for the conveying of material from the discharge pipe 8 into the first distributor 31, which then feeds it into the first storage bin 1 for storage. When the switch 9 controls the material to be discharged through the second pipeline, the material at the end of the second pipeline falls directly into the feed end of the first conveyor 32. The first conveyor 32 then conveys the material to the first distributor 31, which is located at the top of the first storage bin 1. The first distributor 31 evenly distributes the material from the first conveyor 32 to different areas within the first storage bin 1, preventing waste of storage capacity due to localized material accumulation and avoiding the risk of subsequent discharge blockage caused by localized accumulation.
[0031] Understandably, the flow distribution method of the first distributor 31 can be flexibly adjusted. For example, it can be designed as a multi-channel distribution valve. By controlling the opening and closing of different channels, the material can be guided to a specific area in the silo, adapting to the internal structure of different storage silos and ensuring the uniformity of material entering the silo.
[0032] In one feasible implementation, the second feeding assembly 4 includes: The second distributor 41 is disposed on the top of the second storage bin 2; The second conveyor 42 is disposed between the bucket elevator 5 and the second distributor 41, and the feed end of the second conveyor 42 is located below the second end of the third pipeline, and the discharge end is connected to the second distributor 41.
[0033] In this technical solution, the second feeding assembly 4 includes a second distributor 41 and a second conveyor 42. The second conveyor 42 is located between the bucket elevator 5 and the second distributor 41, with its feed end facing directly below the second end of the third pipeline, and its discharge end connected to the second distributor 41. This allows for the conveying of material from the discharge pipe 8 into the second distributor 41, which then feeds it into the second storage bin 2 for storage. When the switch 9 controls the material to be discharged through the third pipeline, the material at the end of the third pipeline falls directly into the feed end of the second conveyor 42. The second conveyor 42 then conveys the material to the second distributor 41, which is located at the top of the second storage bin 2. This distributes the material from the second conveyor 42 evenly to different areas within the second storage bin 2, preventing waste of storage capacity due to localized material accumulation and avoiding the risk of subsequent discharge blockage caused by localized accumulation.
[0034] Understandably, the flow distribution method of the second distributor 41 can be flexibly adjusted. For example, it can be designed as a multi-channel distribution valve. By controlling the opening and closing of different channels, the material can be guided to a specific area in the silo, adapting to the internal structure of different storage silos and ensuring the uniformity of material entering the silo.
[0035] In one feasible implementation, both the first conveyor 32 and the second conveyor 42 are pneumatic chutes.
[0036] In this technical solution, both the first conveyor 32 and the second conveyor 42 are pneumatic chutes. When the material is discharged from the second or third pipeline and falls into the feed end of the corresponding first conveyor 32 and second conveyor 42, compressed air enters the trough through the permeable layer at the bottom of the chute, causing the alumina material to be in a fluidized state. At this time, the fluidity of the material is significantly enhanced, and it can slide naturally with the help of the inclination angle of the first conveyor 32 and the second conveyor 42, so as to achieve smooth conveying from the feed end to the discharge end.
[0037] Understandably, the pneumatic chute adopts a fully enclosed structure, which can effectively prevent dust from flying during the conveying process of alumina, reduce material waste, improve the working environment, and meet environmental protection requirements. During the conveying process, there is no severe friction between the material and the inner wall of the chute, which can reduce the breakage rate of alumina particles and ensure material quality.
[0038] It is understandable that the first conveyor 32 is inclined downward between the bucket elevator 5 and the first distributor 31, and the second conveyor 42 is inclined downward between the bucket elevator 5 and the second distributor 41, to facilitate the flow of materials.
[0039] In one feasible embodiment, a fluorine-loaded material sluice 10 is also included, which is connected to the storage hopper 6 and is used to transport fluorine-loaded alumina material into the storage hopper 6.
[0040] In this technical solution, the alumina conveying system also includes a fluorine-loaded chute 10, which is connected to the storage hopper 6 and is used to convey fluorine-loaded alumina material into the storage hopper 6. The fluorine-loaded alumina material can directly enter the storage hopper 6 through the fluorine-loaded chute 10 without the need for additional transfer equipment.
[0041] In use, after the fluorinated alumina material enters the fluorinated material chute 10, it slides along the inside of the chute towards the inlet of the storage hopper 6, propelled by the chute's own inclination angle or a small amount of airflow, and finally falls into the storage hopper 6 for temporary storage. Compared with traditional pneumatic conveying methods, chute conveying reduces the high-speed friction between the fluorinated alumina and the pipeline, lowers the breakage rate of material particles, and also reduces dust spillage caused by high-pressure airflow.
[0042] In one feasible implementation, a material identification device is also included, which is used to determine the type of material fed into the storage hopper 6.
[0043] In this technical solution, the alumina conveying system also includes a material identification device, which is specifically used to determine the type of material fed into the storage hopper 6. Based on the material identification device, before material enters the storage hopper 6 via the fluorine-loaded chute 10 or other feeding methods, the material identification device quickly detects and identifies it, and feeds the identification result back to the control system, providing a control basis for subsequent conveying path switching. When fluorine-loaded alumina flows into the storage hopper 6 via the fluorine-loaded chute 10, the material identification device identifies it and sends a signal indicating fluorine-loaded alumina; when fresh alumina enters via other feeding methods, it sends a signal indicating fresh alumina. This achieves automatic identification of material types, replacing the traditional manual judgment method and reducing the risk of material mixing due to human error. The identification result directly links to the control system, providing data support for the automatic reversing of the switcher 9 and the operation of the bucket elevator 5, ensuring that different types of materials accurately enter the corresponding storage hoppers. It is understandable that the material identification device can be directly installed at the feed inlet of storage hopper 6 to achieve unified detection, or it can be a material vehicle identification system that stores information on vehicles transporting different types of goods in advance in the control system and identifies the type of material carried by the vehicle by identifying the vehicle information.
[0044] In one feasible implementation, a control system is also included. The control system is electrically connected to the material identification device, the bucket elevator 5, and the switcher 9. The control system controls the bucket elevator 5 to lift the material according to the type of material identified by the material identification device, and then controls the switcher 9 to feed the material into the corresponding first storage bin 1 or second storage bin 2.
[0045] In this technical solution, the alumina conveying system also includes a control system. The control system is electrically connected to the material identification device, the bucket elevator 5, and the switch 9. The control system controls the start and stop of the bucket elevator 5 and the flow direction adjustment of the switch 9 according to the material type signal output by the material identification device, so as to realize the conveying of materials to the corresponding first storage bin 1 and second storage bin 2. The entire conveying process can be completed automatically without manual intervention, which greatly improves the intelligence and automation level of the system.
[0046] In operation, when the material identification device detects that the material entering storage hopper 6 is fresh alumina, it immediately transmits an electrical signal of the fresh alumina to the control system. Upon receiving the signal, the control system first determines whether the material height in storage hopper 6 has reached the start threshold. If the condition is met, it sends a start command to the bucket elevator 5, driving the bucket elevator 5 to lift the fresh alumina from storage hopper 6 to the top discharge port 7. Simultaneously, the control system sends a command to the switcher 9, causing the switcher 9 to adjust its internal channels, allowing the fresh alumina to flow through the first pipeline into the third pipeline, and finally through the third pipeline and the second feeding assembly 4 into the second storage chamber 2. If the material identification device detects fluorinated alumina, the control system will send a start command to the bucket elevator 5 and a command to the switcher 9, causing the fluorinated alumina to enter the first storage chamber 1 through the second pipeline and the first feeding assembly 3. Controlling the material through the control system not only avoids the risks of misjudgment and misoperation that may occur with manual operation, but also automatically matches the conveying path according to the material type, ensuring that the two types of alumina are not mixed.
[0047] In one feasible implementation, a material level detector is also included, which is disposed on the storage hopper 6 and is used to detect the material height inside the storage hopper 6.
[0048] In this technical solution, when fluorinated alumina enters the storage hopper 6 through the fluorinated material chute 10, or when fresh alumina is injected through other feeding methods, the material level detector continuously monitors the material height change in the storage hopper 6. When the material height reaches the preset start threshold, the material level detector sends a signal to the control system, triggering the bucket elevator 5 to start and begin lifting and conveying the material upwards. This achieves automatic monitoring of the material quantity in the storage hopper 6, replacing the traditional method of manual inspection and judgment, and reducing the interruption of conveying or material overflow caused by human negligence.
[0049] Understandably, the level detector can be an ultrasonic level gauge or a radar level gauge.
[0050] See also Figure 3 As shown, the second aspect of this application provides an alumina conveying method. The alumina conveying system employing the above technical solution includes the following steps: Step 1: Identify the type of material using the material identification device and transmit the identified material information to the control system.
[0051] In this technical solution, a material identification device is used to determine the type of material fed into the storage hopper 6. Before the material enters the storage hopper 6 through the fluorine-loaded chute 10 or other feeding methods, the material identification device quickly detects and identifies it, and feeds the identification result back to the control system, providing a control basis for subsequent conveying path switching. When fluorine-loaded alumina flows into the storage hopper 6 through the fluorine-loaded chute 10, the material identification device identifies it and sends a signal for fluorine-loaded alumina; when fresh alumina enters through other feeding methods, it sends a signal for fresh alumina. This achieves automatic identification of material types, replacing the traditional manual judgment method and reducing the risk of material mixing caused by human error. The identification result directly links to the control system, providing data support for the automatic reversing of the switcher 9 and the operation of the bucket elevator 5, ensuring that different types of materials accurately enter the corresponding storage hoppers.
[0052] It is understandable that the material identification device can be directly installed at the inlet of the storage hopper for unified detection, or it can be a material vehicle identification system. Information on vehicles transporting different types of materials is stored in the control system beforehand, and the type of material carried by the vehicle is determined by identifying the vehicle information. The material identification device is used to determine the type of material fed into the storage hopper 6. Before material enters the storage hopper 6 through the fluorine-loaded chute 10 or other feeding methods, the material identification device quickly detects and identifies it, and feeds the identification result back to the control system, providing a control basis for subsequent conveying path switching. When fluorine-loaded alumina flows into the storage hopper 6 through the fluorine-loaded chute 10, the material identification device identifies it and sends a signal indicating fluorine-loaded alumina; when fresh alumina enters through other feeding methods, it sends a signal indicating fresh alumina. This achieves automatic identification of material types, replacing the traditional manual judgment method and reducing the risk of material mixing caused by human error. The identification result directly links to the control system, providing data support for the automatic reversing of the switcher 9 and the operation of the bucket elevator 5, ensuring that different types of materials accurately enter the corresponding storage hoppers.
[0053] Step 2: After the material is fed into the storage hopper 6, when the material level detector detects that the material has reached the target height in the storage hopper 6, the material level detector transmits the detected material position information to the control system. The control system starts the bucket elevator 5 and opens the switch 9 in the discharge pipe 8 according to the type of material. The bucket elevator 5 feeds the material into the corresponding first storage bin 1 or second storage bin 2.
[0054] In this technical solution, when the material identification device detects that the material entering the storage hopper 6 is fresh alumina, it immediately transmits the electrical signal of the fresh alumina to the control system. After receiving the signal, the control system first determines whether the material height in the storage hopper 6 has reached the start threshold. When the level detector detects that the material in the storage hopper 6 has reached the start threshold, the control system sends a start command to the bucket elevator 5, driving the bucket elevator 5 to lift the fresh alumina from the storage hopper 6 to the top discharge port 7. At the same time, the control system sends a command to the switcher 9, causing the switcher 9 to adjust its internal channel, allowing the fresh alumina to flow into the third pipeline through the first pipeline, and finally enter the second storage chamber 2 through the third pipeline and the second feeding assembly 4. If the material identification device detects fluorinated alumina, when the level detector detects that the material in the storage hopper 6 has reached the start threshold, the control system will send a start command to the bucket elevator 5 and a command to the switcher 9, causing the fluorinated alumina to enter the first storage chamber 1 through the second pipeline and the first feeding assembly 3. Controlling the material through a control system not only avoids the risks of misjudgment and misoperation that may occur with manual operation, but also automatically matches the conveying path according to the type of material, ensuring that the two types of alumina are not mixed in the warehouse.
