[0002] In the manufacturing process of anode materials, homogenization mixing in the post-processing stage is a crucial step. Homogenization mixing eliminates batch variations, ensuring product consistency, and optimizes particle size distribution to improve overall product performance. Currently, the triple-eccentric mixing equipment 80 is widely used in the industry. Please refer to [link / reference]. Figure 1 The triple eccentric mixing equipment 80 consists of multiple different barrels. These barrels are arranged in a staggered and tilted manner in three dimensions, forming a structure that is eccentric in terms of center of gravity, axial direction, and vertical direction. During the material discharge process between the multiple barrels, there is a risk of leakage.

[0003] In other words, existing hybrid systems have a high risk of material leakage. Utility Model Content

[0004] The main objective of this invention is to provide a mixing system to address the problem of high material leakage risk in existing mixing systems.

[0005] To achieve the above objectives, this utility model provides a mixing system, comprising: at least one material conveying pipeline, the material conveying pipeline including a feeding device and a buffer bin, the feeding device being connected to the buffer bin; a mixing buffer device, the mixing buffer device including a tank and an airflow mixing component, the discharge end of the buffer bin being connected to the tank, the airflow mixing component being connected to the tank, and the airflow mixing component being used to spray airflow into the tank; and a discharge pipeline, the discharge pipeline being connected to the discharge end of the tank.

[0006] Furthermore, the mixing system also includes a discharge assembly, with the discharge end of the tank connected to the discharge assembly, and the discharge port of the discharge assembly connected to the discharge pipeline.

[0007] Furthermore, the discharge assembly includes a second pipe connector, which includes a second material conveying channel, a second drive mechanism, and an impeller. The second drive mechanism is driven to connect with the impeller, and the impeller is located inside the second material conveying channel. The second drive mechanism is used to drive the impeller to rotate. The two ends of the second pipe connector are respectively connected to the tank and the discharge pipeline.

[0008] Furthermore, the discharge assembly also includes a pipe, one end of which is connected to the tank body, and the other end of which is connected to a second pipe connector.

[0009] Furthermore, the discharge assembly also includes a first pipe connector, which includes a first material conveying channel and a first switching mechanism. The first switching mechanism is located inside the first material conveying channel, and the two ends of the first material conveying channel are respectively connected to the discharge end of the tank and the pipe.

[0010] Furthermore, the tank includes a main body and a bottom connected together, the discharge end of the tank is opened on the bottom wall of the bottom, the airflow mixing component is connected to the bottom and the airflow mixing component is spaced apart from the bottom wall of the bottom.

[0011] Furthermore, the airflow mixing assembly includes multiple nozzles that are connected to the bottom of the tank and are arranged circumferentially along the tank.

[0012] Furthermore, the nozzle includes a spray nozzle that is positioned toward the top of the tank.

[0013] Furthermore, the airflow mixing assembly also includes a main airflow duct and multiple branch airflow ducts, with one end of each branch airflow duct connected to the main airflow duct and the other end of each branch airflow duct connected to a corresponding nozzle.

[0014] Furthermore, the airflow mixing assembly also includes at least one supplementary gas acceleration nozzle, which is connected to the main airflow duct, and the extension direction of the supplementary gas acceleration nozzle is set at an angle to the axial direction of the tank.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0030] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0031] To address the high risk of material leakage in existing hybrid systems, this invention provides a hybrid system.

[0032] like Figures 2 to 8 As shown, the mixing system includes multiple material conveying pipelines 10, a mixing buffer device 20, and a discharge pipeline 40. The material conveying pipeline 10 includes a feeding device 11 and a buffer bin 12, with the feeding device 11 connected to the buffer bin 12. The mixing buffer device 20 includes a tank 50 and an airflow mixing component 30, with the discharge end of the buffer bin 12 connected to the tank 50 and the airflow mixing component 30 connected to the tank 50. The airflow mixing component 30 is used to spray airflow into the tank 50. The discharge pipeline 40 is connected to the discharge end of the tank 50.

[0033] The feeding device 11 can be a powder granule feeder, a vacuum conveyor feeder, or an automatic powder feeder. The buffer silo 12 has a tank structure, and the discharge end of the feeding device 11 is connected to the inlet end of the buffer silo 12 through a pipeline. The material in the feeding device 11 can enter the buffer silo 12 through the pipeline. There are multiple material conveying pipelines 10, and each of the multiple material conveying pipelines 10 is equipped with a buffer silo 12. At least some of the buffer silos 12 are connected to the inlet end of the tank 50 through pipelines.

[0034] By setting at least one material conveying pipeline 10 to transport materials into the tank 50 for mixing, and using an airflow mixing component 30 to spray airflow into the tank 50, the materials inside the tank 50 are blown up to achieve mixing. After mixing, the materials are discharged through the discharge pipeline 40. This application reduces the need for multiple tanks (such as mixing silos before mixing) by setting only a mixing buffer device 20 between the material conveying pipeline 10 and the discharge pipeline 40, thereby reducing the number of times materials are discharged and reducing the risk of material leakage during the discharge process, effectively improving the airtightness of the mixing system. At the same time, this application uses airflow mixing instead of mechanical stirring to reduce energy consumption and improve energy utilization. Airflow mixing also allows for a wider material distribution space, not limited to mixing near the stirring structure, achieving material distribution throughout the buffer space 21 of the entire tank 50, which is conducive to rapid and uniform mixing and improves production capacity.

[0035] In some alternative embodiments, please refer to Figure 1 and Figure 4 The mixing system also includes a discharge assembly 60, which connects to the outlet of the tank 50, and the outlet of the discharge assembly 60 connects to the discharge pipeline 40. Because the airflow mixing assembly 30 blows material from the bottom of the tank 50 to the inlet of the tank 50, a negative pressure easily forms at the bottom of the tank 50, especially near the outlet. This causes material to accumulate at the outlet and make it difficult for it to enter the discharge pipeline 40. By installing the discharge assembly 60 between the outlet of the tank 50 and the discharge pipeline 40, material can be discharged from the tank 50, preventing material accumulation. It should be noted that the bottom of the tank 50 refers to the area from the midpoint of the line connecting the inlet and outlet of the tank 50 to the outlet.

[0036] In some alternative embodiments, please refer to Figure 4 and Figure 7The discharge assembly 60 includes a second pipe connector 62, which includes a second material conveying channel 621, a second drive mechanism 622, and an impeller 623. The second drive mechanism 622 is driven to rotate the impeller 623, which is located within the second material conveying channel 621. By incorporating the second drive mechanism 622 and the impeller 623 within the second pipe connector 62, both ends of the second pipe connector 62 are connected to the tank 50 and the discharge pipeline 40, respectively. The second drive mechanism 622 drives the impeller 623 to rotate, thus discharging the material.

[0037] In some optional embodiments, the second material conveying channel 621 is a tubular structure. One end of the second material conveying channel 621 can be connected to the discharge end of the tank 50, and the other end can be connected to the inlet end of the discharge pipeline 40. The second drive mechanism 622 can be a drive motor. The impeller 623 is located inside the second material conveying channel 621, and the drive end of the second drive mechanism 622 passes through the side wall of the second material conveying channel 621 and is connected to the impeller 623. The second drive mechanism 622 drives the impeller 623 to rotate inside the second material conveying channel 621, and the impeller 623 drives the material in the second material conveying channel 621 to be discharged from the second material conveying channel 621. In this way, the possibility of material accumulating at the discharge end of the tank 50 due to negative pressure can be reduced.

[0038] In some alternative embodiments, please refer to Figure 4 The discharge assembly 60 also includes a pipe 63, one end of which is connected to the tank 50, and the other end of which is connected to the second pipe connector 62. By setting the pipe 63 between the second pipe connector 62 and the tank 50, it can act as an interval, reduce the impact of negative pressure on the discharge of the second pipe connector 62, and facilitate smooth discharge.

[0039] In some alternative embodiments, please refer to Figure 4 and Figure 8The discharge assembly 60 also includes a first pipe connector 61, which includes a first material conveying channel 611 and a first switching mechanism 612. The first switching mechanism 612 is located within the first material conveying channel 611, and both ends of the first material conveying channel 611 are connected to the discharge end of the tank 50 and the pipe 63, respectively. By setting the first pipe connector 61 between the pipe 63 and the discharge end of the tank 50, negative pressure can be blocked. When the discharge assembly 60 cannot discharge material, the first pipe connector 61 can be closed, reducing the impact of negative pressure on the discharge assembly 60 without affecting mixing. After the discharge assembly 60 discharges material smoothly, the first pipe connector 61 can be opened to continue discharging material. For example, the connection state between the first pipe connector 61 and the pipe 63 can be switched by changing the position of the first switching mechanism 612 within the first material conveying channel 611.

[0040] In some optional embodiments, the first switching mechanism 612 includes a first driving mechanism 613 and a first sheet structure 614. The driving end of the first driving mechanism 613 is connected to the first sheet structure 614. The first sheet structure 614 is located within the first material conveying channel 611. The first sheet structure 614 has a first position and a second position. When the first sheet structure 614 is in the first position, the edge of the first sheet structure 614 is abutted against the first material conveying channel 611 to block the first material conveying channel 611. When the first sheet structure 614 is in the second position, at least a portion of the edge of the first sheet structure 614 is spaced apart from the first material conveying channel 611, thereby making room for material conveying.

[0041] In some alternative embodiments, please refer to Figure 1 The tank body 50 includes a main body 55 and a bottom 54 connected to each other. The discharge end of the tank body 50 is located on the bottom wall of the bottom 54. The airflow mixing assembly 30 is connected to the bottom 54 and is spaced apart from the bottom wall of the bottom 54. By placing the airflow mixing assembly 30 at the bottom 54, the material can be blown to the upper space of the tank body 50 for mixing. Simultaneously, the material falls due to gravity, which facilitates circulation and uniform mixing within the tank body 50. Furthermore, the spaced arrangement of the airflow mixing assembly 30 from the bottom wall of the bottom 54 reduces the impact of negative pressure on the material discharge, allowing the material to accumulate at the bottom 54 of the tank body 50 and be discharged through gravity. It should be noted that the bottom of the tank body 50 refers to the area from the midpoint of the vertical line between the inlet and outlet ends of the tank body 50 to the outlet end.

[0042] In some alternative embodiments, the main body 55 has a cylindrical structure.

[0043] In some alternative embodiments, the bottom 54 is a conical structure.

[0044] In some alternative embodiments, please refer to Figure 2 The material conveying pipeline 10 includes a feeding device 11 and a buffer bin 12, with the buffer bin 12 located downstream of the feeding device 11. The feeding device 11 can be a powder granule feeder, a vacuum conveyor feeder, or an automatic powder feeder. The buffer bin 12 has a tank structure, and the discharge end of the feeding device 11 is connected to the inlet end of the buffer bin 12 via a pipeline, allowing material in the feeding device 11 to enter the buffer bin 12 through the pipeline. There are multiple material conveying pipelines 10, each equipped with a buffer bin 12, and at least some of the buffer bins 12 are connected to the inlet end of the tank 50 via pipelines.

[0045] In one specific embodiment, after the first pipe connector 61 is opened, the material enters the second pipe connector 62 through the transfer pipe 63. The rotation of the impeller 623 in the second pipe connector 62 facilitates the rapid flow of the material and can reduce the possibility of the material accumulating at the discharge end of the tank 50 due to the influence of negative pressure.

[0046] In some alternative implementations, please refer to Figure 2 and Figure 3 The tank body 50 also has at least one exhaust port 53, which is located on the same side of the tank body 50 as the inlet 51. The mixing buffer device 20 also includes a dust collector 70, which is located at the exhaust port 53. The exhaust port 53 helps maintain the air pressure within the buffer space 21, preventing excessive air pressure that could lead to safety hazards. The dust collector 70 prevents material leakage from the buffer space 21 through the exhaust port 53, ensuring the purity of the gas flowing out of the exhaust port 53, reducing material leakage, and ensuring a good working environment for operators.

[0047] In some alternative embodiments, the airflow mixing assembly 30 includes a plurality of nozzles 32, which are connected to the bottom of the tank 50 and are arranged circumferentially along the tank 50. By arranging the plurality of nozzles 32 along the axial direction of the tank 50, it is advantageous to spray gas into the tank 50 from different directions, so that the material at different locations in the tank 50 can be mixed evenly.

[0048] In some alternative embodiments, the nozzle 32 includes a nozzle facing the top of the tank 50. This arrangement facilitates spraying material located below the tank 50 to the top of the tank 50, while the material falls under the influence of gravity, thus achieving uniform mixing of the material in a cyclical manner.

[0049] In some alternative implementations, please refer to Figure 5The airflow mixing assembly 30 includes an air source, a main airflow duct 31, and multiple nozzles 32. The main airflow duct 31 is connected to the air source; the nozzles 32 are connected to the main airflow duct 31, and the jetting ends of the nozzles 32 are located within the buffer space 21. The air source is used to supply airflow to the main airflow duct 31. Connecting multiple nozzles 32 to the same main airflow duct 31 simplifies the delivery process, allowing one main airflow duct 31 to supply air to multiple nozzles 32 simultaneously, which simplifies the operation process and also simplifies the structure of the airflow mixing assembly 30.

[0050] Optionally, the air source is used to provide clean compressed air that has been cooled and filtered.

[0051] In some alternative embodiments, the airflow mixing assembly 30 can provide pulsed airflow.

[0052] In some alternative implementations, please refer to Figure 5 The airflow mixing assembly 30 also includes multiple airflow branch pipes 33, one end of which is connected to the main airflow pipe 31, and the other end of each airflow branch pipe 33 is connected to a corresponding nozzle 32. This arrangement facilitates the planning of the position of each nozzle 32 and also facilitates the individual control of each nozzle 32.

[0053] In some alternative embodiments, each nozzle 32 extends axially along the buffer space 21, which helps to reduce the movement of material against gravity.

[0054] Specifically, the air source provides clean compressed air after cold drying and filtration. The air enters the main airflow pipe 31 and the branch airflow pipe 33 and is temporarily stored. According to the control of the pulse valve, the airflow enters the buffer space 21 from the nozzle 32. The compressed air spirals up along the inner wall of the tank 50. The powder material is impacted by the compressed gas and expands. After a single pulse ends, the material begins to settle irregularly due to gravity. At the same time, since the exhaust rate of the dust collector 70 at the top of the tank 50 is much lower than the intake rate of the nozzle 32, the air pressure in the silo is in a continuous process of change, which further aggravates the irregular movement of the material during the settling process. After a few seconds of pause after one pulse ends, the second pulse continues to mix. The pulse-type compressed gas drives the material to continuously carry out diffusion mixing, convection mixing and movement mixing until the material is uniformly mixed.

[0055] In some alternative embodiments, please refer to Figure 5 The airflow mixing assembly 30 also includes at least one supplementary air acceleration nozzle 34, which is connected to the main airflow duct 31, and the extension direction of the supplementary air acceleration nozzle 34 is angled to the axis of the buffer space 21. The supplementary air acceleration nozzle 34 utilizes the effect of pressure reduction and acceleration to increase the airflow velocity and impact range. The low-pressure, high-speed compressed air can drive the flow of the upper material more quickly, which is beneficial to improving the mixing efficiency.

[0056] In some optional embodiments, the air-injection acceleration nozzle 34 is perpendicular to the side wall of the bottom 54, and the side wall of the tank 50 experiences the lowest normal pressure from the material. The low-pressure, high-speed compressed air can more quickly drive the flow of the upper part of the material. At the same time, the nozzle 32 located below is reduced by the vertical gravity of the material, further improving the mixing efficiency. Meanwhile, during the settling process, a high-low pressure alternating airflow is formed in the buffer space 21, which helps to increase the horizontal force on the material and reduce the situation where the material is only affected by gravity, thereby effectively avoiding the sedimentation and stratification phenomenon after the material is mixed.

[0057] In some alternative embodiments, please refer to Figure 6 The gas-injection and acceleration nozzle 34 includes a pipe body 341, a gas-injection pipe 342, and an air inlet pipe 343. The pipe body 341 has a gas-injection chamber 344 and an acceleration chamber 345 that are interconnected. The acceleration chamber 345 is located on the side of the gas-injection chamber 344 near the air outlet. The gas-injection pipe 342 is connected to the gas-injection chamber 344. One end of the air inlet pipe 343 is connected to the air inlet of the pipe body 341, and the other end of the air inlet pipe 343 extends into the acceleration chamber 345. The cross-sectional area of ​​the acceleration chamber 345 perpendicular to the axial direction of the pipe body 341 first decreases and then increases on the side near the air outlet to increase the gas flow rate.

[0058] By setting up the air supply pipe 342, the air supply acceleration nozzle 34 can infer the normal pressure based on the material filling coefficient, and then adjust the air intake of the air supply pipe 342 to control the outlet pressure and flow rate. The compressed air in the air supply pipe 342 merges with the compressed air in the air intake pipe 343, and is accelerated through the acceleration chamber, then ejected into the buffer space 21 at low pressure and high flow rate. Although material may slip into the acceleration chamber 345, the acceleration chamber 345 will automatically form a stable arch within a certain angle range to prevent material from slipping into the air supply chamber 344. However, during the first pulse jet start-up, the airflow does not undergo depressurization and acceleration, and directly contacts the stable arch in the acceleration chamber 345. The low-speed, high-pressure airflow of the first jet causes the material at this point to quickly loosen, providing important assistance for subsequent fluidization, and also preventing the acceleration chamber 345 from experiencing slow fluidization due to insufficient initial jet pressure.

[0059] The mixing of artificial graphite anode materials can be customized by setting the number of pulses and the time according to the material properties and formulation requirements, and the filling coefficient can also be flexibly adjusted within the range of 0.2 to 0.6. Because the mixing method is non-mechanical, involves no contact with foreign matter, no frictional heat generation, and no shear force, it provides good protection for the quality, morphology, and particle size of the graphite anode material.

[0060] The entire mixing process in the mixing buffer device 20 of this application is designed for automated control, involving only low-voltage electrical control and pneumatics, resulting in low installation, operation, and maintenance risks. Furthermore, since there is no mechanical movement within the tank 50 and the weighing system experiences minimal interference, it can function as a buffer tank simply by adding common silo weighing components and sampling ports.

[0061] In one specific embodiment, the mixing system includes three material conveying pipelines 10. Different types of materials are added to the three material conveying pipelines 10 respectively. After weighing and confirming the proportions, the materials are automatically discharged into the mixing buffer device 20. The mixing buffer device 20 still functions as a proportioning bin for static weighing. After confirming that the weight is correct, pulse mixing is initiated. The air-injection acceleration nozzle 34 initially uses high-pressure pneumatics to rapidly fluidize the upper part of the material, followed by low-pressure, high-speed airflow that rapidly fluidizes the upper part of the material. Multiple nozzles 32 at the bottom pulse-spray compressed air into the buffer space 21, circulating and causing the material in the buffer space 21 to move irregularly. After mixing is completed, the mixing buffer device 20 stops working, and the material can be directly stored in the mixing buffer device 20. After sampling and inspection, the discharge port 52 at the bottom opens for discharge, and the material is automatically conveyed according to the capacity of the next process.

[0062] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0063] 1. The use of an integrated hybrid buffer device 20 can reduce material leakage.

[0064] 2. The absence of large mechanical movement within the hybrid buffer device 20 in this application helps reduce energy consumption.

[0065] 3. The airflow material mixing process has higher mixing efficiency, lower energy consumption, and lower cost.
