DETAILED DESCRIPTION
[0030] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0031] In the field of preparation of lithium ion battery positive electrode materials, the filling machine as one of the key equipment has the main task of filling the mixed material after mixing the precursor and lithium source into a container such as sagger 15 during operation. However, the existing filling machine has many problems. A large amount of dust is dispersed into the environment during operation, which not only endangers the health of employees and is difficult to protect the occupational health, but also affects the normal operation of the photoelectric sensor of the equipment, causes the filling precision to be disturbed by dust, and also increases the equipment failure rate. In addition, material overflow during the filling process will cause the material to be contaminated and lead to material waste. The existing filling machine has deficiencies in dust pollution control during the filling process.
[0032] The present embodiment proposes a filling machine dust collection device and a filling machine to solve the problem of insufficient dust pollution control during the filling process of the existing filling machine. The dust cover 1 is connected to the blanking pipe 2 of the filling machine to form a dust collection space, thereby collecting the dust generated at the filling source and preventing its diffusion. The dust collection device 5 sucks away the dust through the dust collection pipeline 6, which can reduce the harm to the health of employees caused by dust dispersion, reduce the equipment failure rate, avoid material pollution and waste, and improve the filling precision.
[0033] In a first aspect, as shown in Figure 1 and Figure 2 The present embodiment provides a filling machine dust collection device mainly comprising a dust cover 1 and a dust collection device 5.
[0034] Specifically, the dust cover 1 is used to be connected to the blanking pipe 2 of the filling machine, the dust cover 1 has a through hole 3 suitable for passing through the blanking pipe 2, and the dust cover 1 has a dust collection space formed around the blanking port 4 of the blanking pipe 2; the dust collection device 5 is in communication with the dust collection space of the dust cover 1 through the dust collection pipeline 6.
[0035] In the present embodiment, the basic structure of the filling machine dust collection device is defined, mainly composed of two parts of dust cover 1 and dust collection device 5. The dust cover 1 has a specific through hole 3, which can make the filling machine's downcomer 2 pass through, and around the downcomer 2's downcomer 4 to build a dust collection space, which is the key area to capture dust. The dust collection device 5 is connected with the dust collection space of the dust cover 1 through the dust collection pipeline 6, forming a complete dust collection channel, laying the foundation for the subsequent dust collection operation.
[0036] Specifically, the dust cover 1 is connected at the filling machine downcomer 2 and forms a dust collection space around the downcomer 4, which can effectively capture dust at the starting point of material filling. When the mixed material falls from the downcomer 2, due to the existence of the dust collection space, the dust is limited in a relatively small area and cannot spread to the surrounding environment. For example, during the filling process of lithium ion battery positive material, the dust generated when the mixed material of precursor and lithium source falls will be blocked in the dust collection space by the dust cover 1, instead of escaping to the entire working area as in traditional filling machines, which reduces the pollution of dust to the environment from the source, greatly reduces the risk of employees inhaling dust, and effectively protects the occupational health of employees. At the same time, through the connection of the dust collection device 5 and the dust collection space of the dust cover 1, the dust in the dust collection space can be timely sucked away. This effectively avoids the influence of dust on the light and photoelectric sensor of the equipment. During the operation of the filling machine, the light and photoelectric sensor plays a key role in accurately controlling the filling amount and position of the material. If dust adheres to the surface of the sensor, it will interfere with the normal transmission of the photoelectric signal, causing the sensor to misjudge and affecting the filling accuracy. The structure of the present dust collection device 5 can ensure that the dust is timely removed, maintaining the cleanliness and normal operation of the sensor, thereby ensuring the filling accuracy of the filling machine and reducing the product quality problems caused by inaccurate filling. At the same time, it also reduces the probability of equipment failure caused by dust, reduces the equipment downtime for maintenance, improves the overall operation stability and reliability of the equipment, prolongs the service life of the equipment, reduces the equipment maintenance cost of the enterprise and the production loss caused by equipment failure. In addition, under the effective collection of dust in the dust collection space and the timely suction of the dust collection device 5, the opportunity for dust to contact with the material is reduced. In traditional filling machines, dust is easily mixed into the material, causing the material to be contaminated and affecting the purity and performance of the material. For lithium ion battery positive material, the decline in material quality may affect the performance and quality of the final battery. The present dust collection device 5 can effectively prevent dust from contaminating the material, ensuring the purity of the material and improving the utilization rate of the material, avoiding waste caused by material contamination, and ensuring the quality stability of each batch of filled material, which is conducive to improving the overall quality level of lithium ion battery positive material preparation and enhancing the competitiveness of the enterprise's products in the market.
[0037] It should be noted that the connection and fixing mode of the dust cover 1 is not limited in this embodiment, and the structure of the connecting piece 8, the connection mode of the dust cover 1 and the dust collection device 5, the setting condition of the dust collection connection port 11, and the shape of the dust cover 1 and the through hole 3 are not limited, because these non-limited parts can be flexibly designed and adjusted according to different filling machine models, working environments and specific needs of enterprises. For example, in some narrow production workshops, the connection mode of the dust cover 1 and the dust collection device 5 may need to be more compact and flexible to adapt to the limited space layout, at this time, flexible and extendable dust collection pipes 6 and special connecting joints can be used to realize efficient dust collection work. As for the shape and size of the dust cover 1, if there are many complex structures or equipment components around the filling machine discharge pipe 2, the rectangular dust cover 1 may need to further optimize its corner design to better fit the surrounding environment and reduce dust collection dead angles. For example, in a production scene with extremely high dust collection requirements, the number and position of the dust collection connection port 11 may need to be accurately calculated and laid out according to the main dust generating area and air flow direction, which may increase the number of dust collection connection ports 11 and use a specific arrangement to ensure that the generated dust can be captured to the greatest extent in the instant of material filling.
[0038] The connection and fixing mode of the dust cover 1 of this embodiment will be described in detail below.
[0039] As shown in Figure 1 and Figure 2 In some embodiments, a plurality of connecting pieces 8 for connecting to the rack 7 of the filling machine are arranged around the part of the dust cover 1 where the through hole 3 is located. The core is to connect the dust cover 1 and the rack 7 of the filling machine through these connecting pieces 8, thereby providing a structural basis for the stable installation of the dust cover 1 on the filling machine, and ensuring that the dust cover 1 can be stably positioned at the corresponding position of the discharge pipe 2.
[0040] Specifically, vibrations are inevitable during the operation of the filling machine, such as vibrations from the material feeding pipe 2 and overall vibrations from the operation of components like the motor. If the dust hood 1 lacks a stable connection structure, it can easily shift or shake due to these vibrations. However, by connecting the dust hood 1 to the frame 7 of the filling machine using several connectors 8 arranged around the through hole 3, the dust hood 1 can be firmly fixed to the filling machine, maintaining its precise position around the material feeding port 4 of the material feeding pipe 2. In this way, the dust collection space formed by the dust hood 1 can always accurately cover the area where dust is generated at the material feeding port 4, preventing the formation of dust collection dead zones due to the displacement of the dust hood 1. This ensures that dust is continuously and effectively collected within the dust collection space throughout the entire material filling process, guaranteeing the stability and continuity of the dust collection effect. This allows the dust collection device 5 to function stably, reducing dust dispersion into the surrounding environment. Furthermore, as a crucial component of the filling machine's dust collection device, the stability of the dust hood 1 is essential for the coordinated operation of the entire filling machine system. Once the dust hood 1 is stably installed, it can work better in conjunction with other components of the filling machine, such as the feed pipe 2 and the subsequent dust collection device 5. A stable dust hood 1 will not collide with or interfere with the feed pipe 2 due to loosening, nor will its position change affect the normal connection of the dust collection pipe 6 or the suction effect of the dust collection device 5. This helps maintain the normal operation of the entire filling machine, reducing malfunctions such as uneven material feeding and poor dust collection caused by problems with the dust hood 1, thereby lowering the overall equipment failure rate, reducing downtime for maintenance due to equipment failure, improving production efficiency, and ensuring the smooth and orderly filling of lithium-ion battery cathode materials. Furthermore, since the dust hood 1 is stably connected to the frame 7 via the connector 8, frequent shaking and friction are avoided. On the one hand, it reduces the risk of wear, deformation, and other damage caused by the instability of the dust hood 1, extending its service life. On the other hand, it also avoids scratches and collisions to surrounding components (such as the surface of the frame 7 and the feed pipe 2) that may be caused by the displacement of the dust hood 1, ensuring that all components of the filling machine operate in a relatively stable and good condition. In the long-term production process, this effectively reduces the frequency of equipment parts replacement and maintenance workload, lowers the cost of equipment maintenance for enterprises, and improves the overall economic efficiency and use value of the equipment, making it more conducive to enterprises to efficiently carry out the preparation of lithium-ion battery cathode materials.
[0041] The structure of connector 8 in this embodiment will be described in detail below.
[0042] like Figure 1 and Figure 2 As shown, in some embodiments, the end of the connector 8 is provided with a bend 9, and the bend 9 is provided with a through hole 10 for passing through a fastener.
[0043] In the present embodiment, the structure of the connecting member 8 is further refined, which provides that the end of the connecting member 8 is provided with a bent portion 9, and a through hole 10 for passing through a fastener is provided on the bent portion 9. Through such a structural design, it is intended to strengthen the stability and reliability of the connection between the connecting member 8 and the frame 7, so that the dust cover 1 can be more stably installed at the corresponding position of the filling machine.
[0044] Specifically, during the operation of the filling machine, various vibrations and external force disturbances may occur, such as mechanical vibrations generated by the operation of the equipment, impact forces during the discharge of materials, etc. The bending part 9 at the end of the connecting piece 8 increases the contact area with the rack 7. Compared with the ordinary straight edge connecting piece 8, the bending part 9 can better fit on the surface of the rack 7, making the stress more evenly distributed. When subjected to external forces, this fitting method can effectively prevent the connecting piece 8 from loosening, deforming, etc. due to excessive local stress, ensuring the tightness of the connection between the connecting piece 8 and the rack 7, allowing the dust cover 1 to be securely fixed on the filling machine and maintaining its accurate position around the discharge pipe 2, thereby ensuring that the dust collection space is always in an effective dust collection state and protecting the dust collection effect from being affected by vibrations during equipment operation. At the same time, the through hole 10 provides a precise fixing channel for fasteners (such as bolts, nuts, etc.). After the fasteners pass through the through hole 10, they can securely fix the connecting piece 8 on the rack 7, further enhancing the stability of the connection. By tightening the fasteners, a tight connection structure can be formed between the connecting piece 8 and the rack 7, effectively resisting various external forces generated during the operation of the filling machine and preventing the dust cover 1 from shifting, moving, etc. This ensures that the dust collection environment created by the dust cover 1 is always stable and reliable, laying a foundation for continuous and efficient dust collection. At the same time, since the dust cover 1 is securely installed on the rack 7 through the connecting piece 8 with the bending part 9 and the through hole 10, it can maintain a stable relative positional relationship with other components of the filling machine. This is crucial for the coordinated operation of the entire filling machine system. For example, it will not interfere with the normal discharge of the discharge pipe 2 due to its own loosening, avoiding collisions or obstructions that may occur due to the shifting of the dust cover 1, ensuring that the materials can smoothly fall from the discharge pipe 2 into containers such as the sagger 15. At the same time, a stable dust cover 1 is also conducive to the stable connection of the dust collection device 5 through the dust collection pipeline 6 and the effective dust collection function, avoiding situations where the connection of the dust collection pipeline 6 becomes loose, leaks, etc. due to the displacement of the dust cover 1, thereby improving the reliability and stability of the entire filling machine equipment operation, reducing the probability of malfunctions caused by poor cooperation between equipment components, reducing the maintenance frequency and downtime of the equipment, and ensuring that the filling operation of lithium ion battery positive materials can be carried out continuously and efficiently. In addition, the stable connection structure can reduce the risk of wear and damage to the dust cover 1 due to frequent shifting and loosening. If the connecting piece 8 is not stable, the dust cover 1 will be in an unstable state for a long time, which may cause deformation, cracking, etc. of its own structure. The stable connection method formed by the combination of the bending part 9 and the through hole 10 effectively avoids these situations, prolonging the service life of the dust cover 1.In addition, the stable dust cover 1 also reduces the damage of friction, collision and the like to the surrounding components (such as the rack 7, the downcomer 2 and the like), reduces the possibility of failure of other components due to the instability of the dust cover 1, thereby reducing the maintenance cost and the replacement frequency of parts of the whole equipment, improving the economic benefit of the equipment in the long term, and being beneficial to the enterprise to better control the cost and improve the production efficiency in the preparation process of the lithium ion battery positive electrode material.
[0045] The connection mode of the dust cover 1 and the dust collection device 5 of the present embodiment is described in detail as follows.
[0046] As shown in Figure 1 and Figure 2 In some embodiments, a dust collection connecting port 11 is arranged on the dust cover 1, a bend 12 is connected to the dust collection connecting port 11, and the bend 12 is further connected to the dust collection pipeline 6. Through such a connection structure design, an effective communication path between the dust cover 1 and the dust collection device 5 is constructed, aiming to enable the airflow and dust in the dust collection process to be smoothly transmitted, and to ensure that the dust collection work can be smoothly carried out.
[0047] Specifically, when the filling machine is running for material filling, a large amount of dust is generated when the material falls from the feeding pipe 2. The dust collection space of the dust hood 1 collects these dusts and transports them to the dust collection device 5 for treatment. The connection mode of the dust collection connecting port 11, the elbow 12 and the dust collection pipeline 6 can skillfully guide the airflow direction in the dust hood 1. When the dust collection device 5 is started to generate negative pressure, the air in the dust hood 1 carries the dust to flow to the dust collection connecting port 11, and the elbow 12 plays a key role in changing the airflow direction, so that the originally straight flowing airflow can smoothly turn along the arc of the elbow 12, and then orderly flow into the dust collection pipeline 6. This reasonable airflow guidance avoids the occurrence of adverse conditions such as turbulence and head-on collision, because turbulence may cause dust to fly around in the dust hood 1 and be difficult to be effectively sucked into the pipeline. Through the optimized airflow path, the dust can be more efficiently guided into the dust collection pipeline 6 under the action of the relatively stable airflow, and finally be collected and treated by the dust collection device 5, greatly improving the dust collection efficiency and reducing the possibility of dust remaining in the dust hood 1 and escaping into the surrounding environment. At the same time, the filling machine is a space with a relatively complex structure and compact layout of various components. Different components occupy specific positions, and the space available for the layout of the dust collection system is often limited and irregular. The design of the dust collection connecting port 11 connecting the elbow 12 and then connecting the dust collection pipeline 6 gives the dust collection system great flexibility in space layout. The elbow 12 can flexibly adjust the direction of the dust collection pipeline 6 according to the actual space limitations and the layout of the surrounding components, so that the dust collection pipeline 6 can bypass other equipment components and smoothly connect the dust hood 1 with the dust collection device 5 located at the appropriate position. For example, when some large structural parts in the filling machine block the straight connection path, the direction of the dust collection pipeline 6 can be easily changed by adjusting the angle of the elbow 12, ensuring that the dust collection system can be integrated into the filling machine completely and smoothly, without being limited by simple straight connection. This adaptability not only facilitates the installation of the dust collection system in the existing filling machine structure, but also provides convenience for subsequent improvement and upgrading of the filling machine. Even if the internal structure of the filling machine is adjusted or new functional components are added, the dust collection system can continue to work normally by adjusting the layout of the elbow 12 and the dust collection pipeline 6, without the need for large-scale modification, effectively reducing the cost of equipment maintenance and upgrading, and improving the universality and expandability of the entire filling machine system. In addition, during the dust collection process, the dust is sucked into the dust collection connecting port 11 from the dust hood 1, and then enters the dust collection pipeline 6 through the elbow 12. The elbow 12 plays an important role in this process. The curved structure of the elbow 12 causes the dust to collide and rub with the inner wall of the elbow 12 when it moves in it. This collision and friction slow down the speed of the dust to some extent, enabling it to enter the dust collection pipeline 6 more orderly and smoothly along the inner wall of the elbow 12, rather than directly colliding and rebounding at high speed or piling up and blocking at the pipeline inlet.The stable dust transmission process is crucial for the dust suction device 5 to continuously and efficiently suck dust, which ensures the stable working state of the dust suction device 5, avoids problems such as unstable suction or pipeline blockage caused by unstable dust transmission, and further ensures that the entire dust suction system can continuously and effectively reduce dust pollution generated during the filling machine working process, maintain the normal operation of the equipment, reduce the equipment failure rate caused by dust problems, prolong the service life of the equipment, and ensure that the lithium ion battery positive material filling work can be carried out stably and reliably.
[0048] The setting of the dust suction connection port 11 of the present embodiment is described in detail below.
[0049] As shown in Figure 1 and Figure 2 In some embodiments, the dust suction connection port 11 is arranged at the top of the dust cover 1, and the dust suction connection port 11 has multiple ports arranged around the through hole 3. This design optimizes the connection layout between the dust cover 1 and the dust suction device 5, aiming to efficiently collect dust in the dust suction space from multiple directions and transmit it to the dust suction device 5.
[0050] Specifically, when the filling machine's downpipe 2 is discharging materials, dust can spread in all directions. The dust suction connection ports 11 are located at the top of the dust hood 1 and are arranged around the through hole 3 in multiple positions, which can suck dust in the dust suction space from different directions. Compared with a single or small number of fixed-position dust suction ports, this multi-directional layout greatly increases the dust suction coverage and reduces the dust suction dead angle. For example, during the filling process of lithium ion battery positive electrode materials, the dust generated by the falling materials may spread upwards and in all directions. The multiple top dust suction connection ports 11 can simultaneously capture dust in different directions, significantly improving the dust suction efficiency, more effectively preventing dust from escaping to the surrounding environment, ensuring the air quality of the working area, reducing the risk of employees inhaling dust, and thus protecting the occupational health of employees. At the same time, the multi-directional dust suction connection ports 11 are beneficial to optimizing the airflow direction in the dust hood 1. When the dust suction device 5 is working, air is sucked into the dust suction connection ports 11 from all directions, forming multiple air currents. These air currents interact to make the air in the dust suction space flow quickly and more evenly. Uniform and stable airflow can more stably carry dust into the dust suction pipeline 6, avoiding the settlement or escape of dust caused by local airflow turbulence. For example, if there is only a single dust suction port, the airflow speed near the dust suction port is faster, while the airflow in the area far from the dust suction port is weaker, which can easily cause dust accumulation or escape. However, the multiple dust suction connection ports 11 can make the airflow evenly distributed in the entire dust suction space, ensuring that dust can smoothly enter the pipeline under the action of airflow, enhancing the stability and reliability of the dust suction process, and enabling the dust suction device 5 to better cope with dust suction needs under different material filling states and environmental conditions. In addition, during the filling process, the speed and flow of material discharging and the physical properties of the material (such as particle size and looseness) may change, and different discharging conditions can cause differences in the location and diffusion range of dust. The multiple dust suction connection ports 11 arranged around the through hole 3 can better adapt to these changes. When the material discharging speed is fast and the flow is large, more dust can be generated in a larger area around the through hole 3. The multiple dust suction connection ports 11 can simultaneously suck dust from different angles, effectively dealing with this situation. When the material properties are special and cause the dust diffusion direction to be more dispersed, the multi-directional dust suction connection ports 11 can also flexibly capture dust, ensuring the effectiveness of dust suction and improving the adaptability and compatibility of the dust suction device 5 to different discharging conditions, ensuring effective control of dust pollution in various situations and ensuring the stable operation of the filling machine and product quality.
[0051] The shape of the dust hood 1 and the through hole 3 of the present embodiment will be described in detail below.
[0052] As Figure 1 and Figure 2As shown, in some embodiments, the dust cover 1 is rectangular, and the through hole 3 is also rectangular. This shape design is limited by the specific structure of the dust cover 1 and its connecting part with the downcomer 2, aiming to better adapt the dust cover 1 to the downcomer 2 and the surrounding structure of the filling machine, so as to improve the overall performance and stability of the dust removal device 5.
[0053] Specifically, the rectangular shape of the dust cover 1 is conducive to forming a relatively regular dust suction space inside. During the dust suction process, the flow characteristics of the air flow are relatively easier to predict and control when the air flow flows in a regular rectangular space. When the air carrying the dust flows from various areas of the dust suction space to the dust suction connecting port 11, the rectangular space can reduce the air flow dead angle and turbulence phenomenon caused by irregular shape. This enables the air flow during the dust suction process to more smoothly transport the dust to the dust suction connecting port 11, and then be sucked away by the dust suction device 5 through the dust suction pipeline 6. For example, if the dust suction space is irregular in shape, there may be slow or stagnant areas of air flow in some corners, causing dust to accumulate and not be effectively sucked. The rectangular space can effectively avoid such problems, improve dust suction efficiency and stability, ensure the continuous and stable operation of the dust suction device 5, reduce dust pollution problems caused by poor dust suction, and improve the cleanliness of the overall working environment of the filling machine. At the same time, the rectangular shape of the dust cover 1 is conducive to forming a relatively regular dust suction space inside. During the dust suction process, the flow characteristics of the air flow are relatively easier to predict and control when the air flow flows in a regular rectangular space. When the air carrying the dust flows from various areas of the dust suction space to the dust suction connecting port 11, the rectangular space can reduce the air flow dead angle and turbulence phenomenon caused by irregular shape. This enables the air flow during the dust suction process to more smoothly transport the dust to the dust suction connecting port 11, and then be sucked away by the dust suction device 5 through the dust suction pipeline 6. For example, if the dust suction space is irregular in shape, there may be slow or stagnant areas of air flow in some corners, causing dust to accumulate and not be effectively sucked. The rectangular space can effectively avoid such problems, improve dust suction efficiency and stability, ensure the continuous and stable operation of the dust suction device 5, reduce dust pollution problems caused by poor dust suction, and improve the cleanliness of the overall working environment of the filling machine. In addition, the rectangular dust cover 1 has good stability in structure. Its four edges and four corners are relatively regular in structure, and can more evenly disperse the stress when subjected to external forces such as vibration and material impact during the operation of the filling machine, reducing the risk of deformation or damage caused by excessive local stress. In terms of installation, the rectangular shape is convenient for connecting and fixing with the rack 7 of the filling machine and other related components. For example, when the dust cover 1 is connected to the rack 7 through the connecting piece 8, the edges of the rectangular shape are easier to determine the connection position and angle, making the installation process more convenient and quick, and the installed dust cover 1 is more stable in position and is less likely to shift during use, ensuring the reliable installation and long-term stable operation of the dust suction device 5 on the filling machine, reducing equipment failures and poor dust suction caused by unstable installation of the dust cover 1, and improving the overall reliability and production efficiency of the filling machine.
[0054] In a second aspect, as Figure 1 and Figure 2As shown, the filling machine provided by the embodiment mainly comprises a rack 7, a blanking pipe 2 and the filling machine dust collection device, wherein the blanking pipe 2 is connected to the rack 7, and the dust collection cover 1 of the filling machine dust collection device is connected to the blanking pipe 2.
[0055] In the embodiment, the connection mode of the dust collection device 5 and the filling machine is defined, and by organically combining the dust collection device 5 with the main body structure of the filling machine, the dust collection function becomes a part of the overall function of the filling machine.
[0056] Specifically, during the filling of lithium-ion battery positive electrode material, the dust hood 1 is connected at the lower pipe 2, which can effectively control the dust at the source of material filling. When the mixed material falls from the lower pipe 2, the dust space of the dust hood 1 can timely capture the generated dust, and the dust suction device 5 can suck away the dust through the dust suction pipeline 6. This integrated design avoids the situation that the dust is first diffused to the surrounding environment and then treated, greatly improves the efficiency of dust collection, effectively reduces the amount of dust escaping into the environment, reduces the harm to the health of employees, and protects the occupational health. At the same time, since the dust suction is carried out at the same time as the material filling, it can effectively prevent the pollution of the dust to the light sensor of the equipment, ensure the normal operation of the sensor, improve the filling accuracy, reduce the failure rate of the equipment caused by dust, avoid the waste of materials due to dust pollution during the filling process, reduce the waste of materials, and improve the working performance and reliability of the filling machine. At the same time, the dust suction device 5 is integrated into the structure of the filling machine, making the overall structure of the filling machine more compact and reasonable. Compared with separately setting up a dust suction device outside the filling machine and connecting it through a complex pipeline, this integrated design reduces the additional space occupation, so that the filling machine can be more reasonably arranged with other related equipment and facilities in a limited production site. For example, in some cases where the production workshop space is limited, there is no need to reserve a large area of installation space for a separate dust suction device, and the integration of the filling machine structure and the dust suction device 5 improves the space utilization rate and facilitates the overall maintenance and management of the equipment. In addition, the integrated design reduces the connecting parts and complex linkage mechanisms between the dust suction system and the filling machine, reduces the equipment operation problems caused by improper connection or linkage failure, improves the stability and operation efficiency of the equipment, and is beneficial to the enterprise to improve the production efficiency and reduce the production cost. In addition, after the dust suction device 5 and the rack 7, the lower pipe 2 and other components of the filling machine form an organic whole, the components can work better. The dust hood 1 is stably connected to the lower pipe 2 through the connecting piece 8, and its position is relatively fixed and will not easily displace due to external factors, ensuring that the dust suction space always accurately covers the area of the lower opening 4 and stably collects dust. At the same time, the dust suction device 5 and other functional components of the filling machine (such as the subsequent material conveying components) can cooperate with each other during operation, and will not interfere or conflict due to the independent operation of the dust suction system. For example, when the filling machine is performing the lower filling operation, the dust suction device 5 can simultaneously perform the dust suction work, and the coordinated operation of the two ensures the smooth progress of the entire filling process, reduces the problems such as equipment downtime and failure caused by the incoordination of components, improves the continuous operation time and production capacity of the filling machine, and provides a strong guarantee for the efficient and stable production of lithium-ion battery positive electrode material.
[0057] It should be noted that the present embodiment does not limit the structure of the filling machine, such as the structure of the jacking device 13 of the filling machine, the structure of the jacking device 13 and the internal device of the assembly box, and other structural components of the filling machine, because these un-limited parts can be flexibly designed and optimized according to actual production needs, process characteristics, and enterprise cost budget and other factors.
[0058] The structure of the jacking device 13 of the filling machine of the present embodiment will be described in detail below.
[0059] As shown in Figure 1 and Figure 2 In some embodiments, the filling machine further comprises a jacking device 13, which has a lifting end 14 opposite to the feeding pipe 2, and the lifting end 14 is adapted to be provided with a sagger 15 for filling. The core is to flexibly adjust the position of the sagger 15 through the jacking device 13 to better adapt to the feeding operation of the feeding pipe 2, and to improve the accuracy and convenience of filling.
[0060] Specifically, during the filling process of lithium-ion battery positive electrode materials, different production requirements may require the use of different specifications and sizes of the sagger 15, or have diversified requirements for the filling amount, filling height, etc. The presence of the jacking device 13 allows the height position of the sagger 15 to be accurately adjusted through its lifting end 14, ensuring that the sagger 15 and the discharge port 4 of the discharge pipe 2 are in the most suitable relative position. For example, when it is necessary to fill materials into smaller saggers 15, the sagger 15 can be lifted to the appropriate height by the jacking device 13, so that the materials can accurately fall into the sagger 15, avoiding waste and pollution to the surrounding environment caused by materials spilling out of the sagger 15. Similarly, for cases with strict filling height requirements, uniform and accurate filling can also be achieved by precisely controlling the position of the sagger 15, ensuring filling accuracy and improving the consistency of product quality, which helps to improve the overall level of lithium-ion battery positive electrode material preparation. At the same time, since the jacking device 13 can quickly and flexibly adjust the position of the sagger 15, the filling machine does not need to spend a lot of time manually adjusting the relative position of the sagger 15 and the discharge pipe 2 when performing different batches or different types of material filling operations, saving operation time and speeding up the pace of the entire filling process. Moreover, accurate position control reduces problems such as material accumulation and blockage caused by poor discharge position, and materials can flow smoothly from the discharge pipe 2 into the sagger 15, ensuring the continuity of material filling and further improving the working efficiency of the filling machine, so that more filling tasks can be completed in a unit of time, meeting the needs of enterprises to produce large-scale lithium-ion battery positive electrode materials. In addition, the relative design of the jacking device 13 and the discharge pipe 2, combined with the structure of the dust hood 1 connected to the discharge pipe 2, allows the dust suction operation and the material filling to be better coordinated. When the position of the sagger 15 is accurately adjusted by the jacking device 13, the dust suction space formed by the dust hood 1 can more effectively cover the material falling area, because the sagger 15 is in the appropriate position, the range of dust generation and diffusion is relatively more predictable and controllable, and the dust suction device 5 can more efficiently suck the dust generated during the filling process. For example, if the sagger 15 is too high or too low, it may cause the dust to escape beyond the effective capture area of the dust hood 1 when the material falls, and the jacking device 13 ensures that the sagger 15 is in the best position, enhancing the pertinence and effectiveness of dust suction, reducing dust pollution to the working environment, protecting the occupational health of employees, and also avoiding the adverse effects of dust on other parts of the equipment (such as photoelectric sensors, etc.), maintaining stable operation of the equipment, reducing equipment failure rate, and prolonging equipment service life. Furthermore, in the face of various sagger 15 specifications and filling conditions under different customer or production process requirements, the jacking device 13 gives the filling machine greater versatility and adaptability. Whether it is a large-capacity or small-capacity sagger 15, or a sagger 15 with special shape and height requirements, it can be adapted through the lifting end 14 of the jacking device 13, so that the filling machine can meet diversified use scenarios without the need for large-scale structural modification.This improves the utilization of the equipment, reduces the cost of purchasing multiple specific filling machines to meet different production needs, and improves the production flexibility and market competitiveness of the enterprise in the field of lithium ion battery positive material preparation as a whole.
[0061] In addition, in other embodiments, a time relay is arranged on the jacking mechanism, which serves to accurately control the lifting action time of the jacking device 13, thereby further optimizing the matching process between the sagger 15 and the feeding pipe 2, and improving the automation and precision of the filling operation. That is, whether a time relay or other device for controlling the lifting action time of the jacking device 13 is arranged on the jacking mechanism, it belongs to the protection scope of the present embodiment.
[0062] The jacking device 13 assembly box structure and the internal device of the assembly box of the present embodiment will be described in detail below.
[0063] As shown in Figure 1 and Figure 2 In some embodiments, the filling machine further comprises a jacking device 13 assembly box, which further comprises a position detection device 16 for detecting the position of the sagger 15 on the jacking device 13 and a main control 17 electrically connected with the position detection device 16, the main control 17 being used to control the feeding of the feeding pipe 2 and the dust collection of the dust collection device 5. This design aims to realize the automatic and precise control of the filling and dust collection operations, and improve the intelligent degree of the overall equipment operation.
[0064] Specifically, in the filling process of lithium-ion battery cathode material, accurate control of the amount and timing of the material is a key factor to ensure product quality. The position detection device 16 monitors the position of the kiln 15 on the jacking device 13 in real time and transmits relevant position information to the main control 17. According to these accurate position data, the main control 17 can accurately control the material feeding operation of the feeding pipe 2, such as determining when to start feeding, the speed of feeding, and the specific duration of feeding, etc. For example, when the kiln 15 is accurately positioned, the main control 17 can trigger the feeding pipe 2 to feed the material at a pre-set reasonable speed, avoiding problems such as uneven filling, overflow, etc. caused by early, late, too fast or too slow feeding, ensuring that each filling can meet the accurate filling requirements, improving the filling accuracy, making the final prepared lithium-ion battery cathode material product quality more stable, reliable, and meeting the production standards. At the same time, the main control 17 synchronously intelligently controls the dust suction operation of the dust suction device 5 according to the kiln 15 position information from the position detection device 16. Since the dust suction cover 1 surrounds the feeding port 4 of the feeding pipe 2, the best dust suction effect is closely related to the position of the kiln 15. When the main control 17 knows that the kiln 15 is in a specific position, it can start the dust suction device 5 in advance or adjust the suction power and other parameters of the dust suction device 5, ensuring that the dust suction and feeding processes are closely coordinated. For example, when the kiln 15 is just in place to receive the material, the main control 17 can immediately increase the suction power of the dust suction device 5, so that the dust generated during the material falling process can be timely and efficiently sucked away, avoiding the spread of dust in the working environment, reducing the impact of dust on key components such as photoelectric sensors of the equipment, reducing equipment failure rate, and also protecting the occupational health of employees, improving the stability and cleanliness of the entire filling machine system operation. In addition, through the cooperation of the position detection device 16 and the main control 17, the operation of the entire filling machine realizes automatic and intelligent control. Originally, the process of controlling feeding and dust suction required continuous observation, judgment and manual operation, which can now be automatically completed by the system. This not only greatly reduces the workload and possible human errors of manual operation, improves production efficiency, but also enables the filling machine to operate stably and accurately for a long time, especially in large-scale and continuous lithium-ion battery cathode material production, the advantages of automatic control are more obvious, which can ensure the quality consistency of each batch of products, help enterprises better control production progress and improve market competitiveness. Furthermore, in the face of different specifications of the kiln 15, different material properties and diversified production process requirements, the cooperation of the position detection device 16 and the main control 17 enables the filling machine to quickly adapt to these changes. No matter how the size of the kiln 15 changes or how the specific situation of the material feeding changes, the position detection device 16 can accurately feedback the kiln 15 position information, and the main control 17 can flexibly adjust the relevant parameters of feeding and dust suction according to the information, ensuring that the filling and dust suction operations are always in the best state.For example, when replacing the different capacity of the sagger 15, the equipment does not need to be manually debugged complicatedly, but can automatically adapt to the new filling requirements, realize accurate filling and effective dust collection, enhance the universality and adaptability of the filling machine in different application scenarios, prolong the application period of the equipment, and reduce the cost of frequent replacement of equipment due to equipment limitations.
[0065] In addition, in other embodiments, the position detection device 16 can be selected as an optical sensor. The optical sensor can accurately and quickly capture the position change of the sagger 15 on the jacking device 13 due to its high precision, non-contact detection, and fast response speed. The working principle is based on the photoelectric effect. When the sagger 15 is in the corresponding position, the receiving end can sense the change when the light is blocked or reflected, and then transmit the corresponding electrical signal to the main control 17. The main control 17 implements accurate control of the discharging of the discharging pipe 2 and the dust collection of the dust collection device 5 based on the accurate signal received. That is, whether the position detection device 16 is set as an optical sensor or other device belongs to the protection scope of the present embodiment.
[0066] The other structural components of the filling machine of the present embodiment will be described in detail below.
[0067] As shown in Figure 1 and Figure 2 In some embodiments, the filling machine further comprises a filling bin 18, an air hammer 19, a filling buffer bin 20, and a weighing device 21. The filling bin 18 is connected with the discharging pipe 2; the air hammer 19 is connected to the filling bin 18; the filling buffer bin 20 is connected to the filling bin 18; and the weighing device 21 is connected to the bottom of the filling buffer bin 20. Through the cooperation of these components, the functions of material conveying, processing, and accurate control of the filling machine are improved, and the material filling process is more stable, accurate, and efficient.
[0068] Specifically, the filling bin 18 serves as a container to store the material to be filled, providing a stable source of material for the entire filling process. In the preparation of lithium-ion battery cathode materials, it can accommodate a certain amount of mixed material after the precursor is mixed with the lithium source, ensuring that the production will not be interrupted due to insufficient material supply during continuous filling operations, thus ensuring the continuity of production. For example, on a large-scale production line, the filling bin 18 has sufficient capacity to store material, allowing the filling machine to continuously fill the saggers 15 for a long time, thereby improving overall production efficiency. At the same time, the air hammer 19 is connected to the filling bin 18, and its main function is to prevent the material from clumping or clogging in the filling bin 18 through periodic vibration. Because some materials may be prone to sticking together due to their own physical properties (such as humidity, particle size, and distribution), the vibration generated by the air hammer 19 can keep the material loose, ensuring that the material can flow smoothly from the filling bin 18 into the downpipe 2, avoiding problems such as uneven material flow and filling interruptions caused by material clogging, further maintaining the stability of material delivery, reducing the potential risk of equipment failure, and ensuring the stable operation of the filling machine. At the same time, the filling buffer bin 20 is connected between the filling bin 18 and the downpipe 2, playing a key role in buffering the material flow. It can receive material from the filling bin 18 and deliver it to the downpipe 2 at a relatively uniform and stable flow rate. Different production requirements may have different requirements for the filling speed and amount of material, and the filling buffer bin 20 can adjust the material flow according to actual conditions to avoid large and small material flow, making the material entering the downpipe 2 more stable and orderly, thereby ensuring the uniformity and accuracy of the material flow. For example, when precise control of the amount of material filled into the saggers 15 each time is required, the filling buffer bin 20 can achieve precise control of the material flow by its buffering and adjusting functions, in cooperation with subsequent weighing devices 21, etc., to improve filling accuracy and ensure product quality consistency. The weighing device 21 is installed at the bottom of the filling buffer bin 20 and can monitor the weight change of the material in the filling buffer bin 20 in real time. This weight data is crucial for precise control of the material flow, as it can feed back real-time weight information to the control system (main control 17), which can accurately adjust the downpipe 2's downpipe speed, downpipe time, and other parameters based on the feedback data to achieve closed-loop control of the material filling amount. For example, when the preset filling weight is reached, the main control 17 can stop the downpipe 2 from discharging to avoid waste or affect product quality due to overfilling, and also prevent insufficient filling that does not meet production requirements, improving the accuracy and reliability of the entire filling process. In addition, these components work together with the dust collection device 5 to create an efficient, accurate, and environmentally friendly lithium-ion battery cathode material filling system. During the entire process of material flowing from the filling bin 18, passing through the filling buffer bin 20, and then being filled into the saggers 15 from the downpipe 2, the dust collection device 5 can continuously collect and process dust generated at each stage.For example, the air hammer 19 vibrates the filling chamber 18, which may generate a small amount of dust when loosening the material; the dust collection device 5 can remove this dust in a timely manner. Dust generated during the feeding process through the feeding pipe 2 can also be effectively captured. This ensures the normal progress of material filling while significantly reducing dust emissions into the environment, minimizing harm to employee health and adverse effects on equipment, improving the cleanliness and safety of the entire production environment, and extending equipment lifespan while reducing maintenance costs. Through close cooperation between components, the overall efficiency and product quality of the filling machine are significantly improved. Smooth material conveying, precise flow control, and effective dust collection ensure that each filling operation is completed accurately and stably, reducing production stoppages and product defects caused by material problems, equipment malfunctions, or dust pollution. In large-scale lithium-ion battery cathode material production, this efficient and stable filling machine system can meet the production needs of high-quality products, enhance the company's competitiveness in the market, and bring better economic benefits.
[0069] In other embodiments, the weighing device 21 includes a weighing sensor, which is fixed in the middle of the hopper. By using a weighing sensor, the weight distribution of the material at different locations within the buffer hopper can be more accurately perceived. Compared to using the weighing device 21 only at the bottom, a weighing sensor in the middle position can avoid measurement errors caused by uneven material accumulation or impact during feeding. In other words, whether or not a weighing sensor is used on the weighing device 21, it falls within the scope of protection of this embodiment.
[0070] like Figure 1 and Figure 2 As shown in the figure, the working process of a filling machine dust collection device and a filling machine in this embodiment is as follows:
[0071] 1. Installation of Dust Hood 1: The dust hood 1 is installed at the feed pipe 2 of the filling machine using several connectors 8 arranged around the through hole 3. The bent part 9 and through hole 10 at the end of the connector 8 are designed to securely connect the dust hood 1 to the frame 7 with fasteners, ensuring that it will not shift due to external forces during equipment operation and will always be in an effective dust collection position. At the same time, the dust hood 1 is designed to be rectangular, and its through hole 3 is also rectangular. This shape facilitates a tight and stable connection with the feed pipe 2, and can fully cover the feed inlet 4 area, reducing dust escape dead zones and facilitating the dust collection function.
[0072] 2. Prepare the dust collection related connection: a plurality of dust collection connection ports 11 are arranged around the top of the dust collection cover 1 through the hole 3, and an elbow 12 is connected on the dust collection connection port 11, and the elbow 12 is connected with the dust collection pipeline 6, the elbow 12 can guide the airflow in the dust collection cover 1 to turn smoothly into the pipeline, give the dust collection pipeline 6 flexibility, adapt to the internal layout of the filling machine, facilitate the connection of the dust collection device 5 and the dust collection cover 1 and determine the appropriate installation position, and facilitate the efficient entry of dust into the pipeline under the action of stable airflow, reduce residual and dispersion, etc.
[0073] 3. The sagger 15 is in place and the related detection control: the lifting end 14 of the jacking device 13 is opposite to the feeding pipe 2, the sagger 15 used for filling is arranged on the lifting end 14, the position detection device 16 detects the position of the sagger 15 in real time, and transmits the information to the main control 17, the main control 17 controls the feeding time and the feeding amount of the feeding pipe 2 according to the position of the sagger 15, and ensures that the material is accurately filled into the sagger 15. In addition, the main control 17 controls the dust collection operation of the dust collection device 5 according to the position of the sagger 15, for example, when the sagger 15 is in place and ready to be filled, the dust collection device 5 is started in advance or the dust collection power is adjusted, so that the dust collection and filling processes are closely matched.
[0074] 4. Material filling and dust collection are cooperated: the filling bin 18 stores the material to be filled, the air hammer 19 hammers the filling bin 18 to prevent the material from being blocked, so that the material flows smoothly into the feeding pipe 2, the filling buffer bin 20 buffers the material flow, so that the material enters the feeding pipe 2 more uniformly and stably, and the weighing device 21 monitors the weight of the material in the filling buffer bin 20 in real time, providing data support for accurate control of the feeding amount. At the same time, in the process of filling the sagger 15 with the material falling from the feeding pipe 2, the dust collection space formed by the dust collection cover 1 around the feeding port 4 surrounds and collects the dust generated, and the dust collection device 5 sucks away the dust in the dust collection space through the dust collection pipeline 6, reduces the dust dispersion to the environment, avoids the dust affecting the normal operation of the photoelectric sensor of the equipment, reduces the equipment failure rate, reduces the material pollution and waste, improves the filling precision, realizes the cooperative operation of filling and dust collection, and guarantees the efficient, precise and environmentally friendly operation of the whole lithium ion battery positive material filling system.
[0075] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and variations can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and variations fall within the scope of the present application.
