Description

Technical Field

[0001] This application belongs to the field of graphite anode material preparation technology, and in particular relates to a coating granulation device. Background Technology

[0002] In the preparation of graphite anode materials, granulation and coating processes are generally used. Granulation not only increases the compaction density of the material but also optimizes the structural performance of the electrode, enabling it to provide higher energy density and longer cycle life in the battery. Coating, on the other hand, can improve the surface properties of the material, such as reducing surface defects and optimizing interface properties, thereby improving the rate performance and safety of the battery.

[0003] In existing technologies, liquid asphalt and coke particles are used for processing. Specifically, liquid asphalt and coke particles are first added to a heating device, where they are then heated and continuously stirred. As the temperature rises, the volatiles in the liquid asphalt gradually evaporate, causing the viscosity of the liquid asphalt to gradually increase. The coke particles are then bound together by the liquid asphalt, ultimately achieving the granulation effect.

[0004] However, such an operation not only requires a large amount of heat to heat the liquid asphalt to the working temperature, but also takes a considerable amount of time for the heating equipment to heat up to the working temperature and cool down to the appropriate temperature, resulting in high energy consumption and long processing time for the entire process. Utility Model Content

[0005] This invention provides a coating granulation device, which aims to solve the technical problems of high energy consumption and long processing time in the granulation process.

[0006] To achieve the above objectives, this utility model proposes a coating granulation device for granulating a mixture of liquid asphalt and coke particles, the coating granulation device comprising:

[0007] The housing has a cavity enclosed and the housing also has an air outlet communicating with the cavity;

[0008] A first cutting tool, comprising a grinding blade and a shovel blade coaxially rotatably disposed within the cavity, with a gap between the grinding blade and the bottom wall of the housing. The grinding blade is used to grind and rub the liquid asphalt within the gap to cause the volatile components in the liquid asphalt to evaporate. The shovel blade is used to scoop up the mixture located within the gap.

[0009] The second cutter is rotatably disposed within the cavity and spaced apart from the first cutter. The second cutter is used to break up the mixture scooped up by the shovel.

[0010] In one embodiment, the grinding blade has a grinding surface that is curved and protrudes toward the bottom wall. Along the rotation direction of the grinding blade, the grinding surface has a first side and a second side that are arranged opposite to each other, with the first side located in front of the second side. The distance between the first side and the bottom wall is greater than the distance between the second side and the bottom wall, and the gap is formed between the grinding surface and the bottom wall.

[0011] In one embodiment, the grinding blade further includes a plurality of grinding protrusions arranged side by side on the second side.

[0012] In one embodiment, the distance between the second side and the bottom wall ranges from 3 to 5 millimeters.

[0013] In one embodiment, the shovel has a scooping side and a scooping bottom, and along the rotation direction of the shovel, the distance between the front side of the scooping side and the bottom wall is smaller than the distance between the rear side of the scooping side and the bottom wall.

[0014] The bottom surface of the shovel is connected to the front side of the side surface of the shovel, and the bottom surface of the shovel is positioned opposite the bottom wall.

[0015] In one embodiment, the shovel includes a first shovel portion and a second shovel portion connected to each other. Both the first shovel portion and the second shovel portion are arranged at an angle to the bottom wall, and the first shovel portion and the second shovel portion are also arranged at an angle to each other.

[0016] Along the rotation direction of the shovel blade, the front sides of the first shovel portion and the second shovel portion cooperate to form the shovel side surface, and the sides of the first shovel portion and the second shovel portion facing the bottom wall cooperate to form the shovel bottom surface.

[0017] In one embodiment, the shovel further includes a plurality of shovel protrusions arranged side by side on the bottom surface of the shovel.

[0018] In one embodiment, multiple grinding blades and multiple shovels are provided, and the multiple grinding blades and multiple shovels are spaced apart along the rotation direction of the first blade, and at least one shovel is provided between two adjacent grinding blades, and at least one grinding blade is provided between two adjacent shovels.

[0019] In one embodiment, the second tool includes a plurality of first and second blades that are coaxially rotatably arranged. The first and second blades are staggered along the output shaft extension direction of the second tool, and the first and second blades are arranged at an angle.

[0020] In one embodiment, the coating granulation equipment further includes a base, and the first cutter further includes a rotation drive and a transmission assembly. The rotation drive and the housing are arranged side by side on the base. One side of the transmission assembly is connected to the rotation drive, and the other side of the transmission assembly is connected to the grinding blade and the shovel blade.

[0021] The beneficial effects of embodiments of this utility model are as follows: This utility model uses coaxially rotating grinding and shovel blades within the cavity. The rotation of the grinding blades crushes the mixture located within the interval, causing the liquid asphalt to collide and rub against the bottom wall of the shell and between the liquid asphalt molecules, generating instantaneous high temperatures. This causes the volatiles in the liquid asphalt to evaporate and be discharged from the outlet, increasing the viscosity of the liquid asphalt. The coke particles are then bound together by the increased viscosity of the liquid asphalt. The shovel blade scoops the mixture from the interval and throws it towards the second blade. The second blade, rotating within the cavity, can break up the coke particle mixture that is bound together with low bonding strength, allowing it to re-enter the first blade for bonding. This cycle continues, ultimately ensuring qualified bonding strength and uniform particle size, achieving a granulation effect. This setup eliminates the need for additional heating equipment, reducing energy consumption. Furthermore, it only affects the crushed liquid asphalt, eliminating the need for all the liquid asphalt in the cavity to be heated to the required temperature, thus reducing waiting time. Simultaneously, there is no waiting time for the heating equipment to cool to the appropriate temperature. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. In the present utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0032] In the preparation of graphite anode materials, granulation and coating processes are generally used. Granulation not only increases the compaction density of the material but also optimizes the structural performance of the electrode, enabling it to provide higher energy density and longer cycle life in the battery. Coating, on the other hand, can improve the surface properties of the material, such as reducing surface defects and optimizing interface properties, thereby improving the rate performance and safety of the battery.

[0033] In existing technologies, liquid asphalt and coke particles are used for processing. Specifically, liquid asphalt and coke particles are first added to a heating device, where they are then heated and continuously stirred. As the temperature rises, the volatiles in the liquid asphalt gradually evaporate, causing the viscosity of the liquid asphalt to gradually increase. The coke particles are then bound together by the liquid asphalt, ultimately achieving the granulation effect.

[0034] However, such an operation not only requires a large amount of heat to heat the liquid asphalt to the working temperature, but also takes a considerable amount of time for the heating equipment to heat up to the working temperature and cool down to the appropriate temperature, resulting in high energy consumption and long processing time for the entire process.

[0035] This utility model provides a coating granulation equipment 100, which aims to solve the technical problems of high energy consumption and long processing time in the granulation and coating process.

[0036] First, it should be noted that the liquid asphalt referred to in this solution is asphalt that is liquid at room temperature, i.e., 20℃ to 30℃. The volatile matter content of this liquid asphalt is greater than 80%.

[0037] Please see Figures 1 to 6 In one embodiment of this utility model, the coating granulation equipment 100 is used to granulate a mixture of liquid asphalt and coke particles. The coating granulation equipment 100 includes a shell 1, a first cutter 2 and a second cutter 3. The shell 1 is provided with a cavity 11 and an air outlet 122 communicating with the cavity 11. The first cutter 2 includes a grinding cutter 21 and a shovel cutter 22 coaxially rotatably disposed in the cavity 11. A gap is provided between the grinding cutter 21 and the bottom wall 14 of the shell 1. The grinding cutter 21 is used to grind and rub the liquid asphalt in the gap to make the volatiles in the liquid asphalt evaporate. The shovel cutter 22 is used to shovel up the mixture located in the gap. The second cutter 3 is rotatably disposed in the cavity 11 and spaced apart from the first cutter 2. The second cutter 3 is used to disperse the mixture shoveled up by the shovel cutter 22.

[0038] In this embodiment, the cavity 11 formed by the shell 1 provides a space for the liquid asphalt and coke particles to bond within the cavity 11. A coaxially rotating grinding blade 21 and a shovel 22 are arranged within the cavity 11. The rotation of the grinding blade 21 crushes the mixture located within the gap, causing the liquid asphalt to collide and rub against the bottom wall 14 of the shell 1 and between the liquid asphalt molecules, generating instantaneous high temperatures. This causes the volatiles in the liquid asphalt to evaporate and be discharged from the vent, increasing the viscosity of the liquid asphalt. The coke particles are then bonded together by the increased viscosity of the liquid asphalt. The shovel 22 scoops the mixture from the gap and throws it towards the second blade 3. The second blade 3, rotating within the cavity 11, can break up the coke particle mixture that is bonded together but has weak bonding strength, allowing it to re-enter the first blade 2 for bonding. This cycle continues until the bonding strength is qualified and the particle size is uniform, achieving the granulation effect. At the same time, by adjusting the rotation speed of the first cutter 2 and the second cutter 3, the volatile matter can be controlled within a certain range, the bonding strength between coke particles can be weakened, and the coke particles can be prevented from sticking together, thereby achieving the effect of coating without granulation.

[0039] Understandably, this setup eliminates the need for additional heating equipment, reducing energy consumption. Furthermore, it only affects the compacted liquid asphalt, eliminating the need for all the liquid asphalt in cavity 11 to be heated to the required temperature simultaneously, thus reducing waiting time. Simultaneously, there is no waiting time for the heating equipment to cool to the appropriate temperature.

[0040] Understandably, the grinding blade 21 can crush and rub the liquid asphalt, causing the volatiles in the liquid asphalt to evaporate, while the shovel blade 22 can throw the adhered coke particles toward the second blade, and also prevent the excessive accumulation of coke particles on the bottom wall 14, thus reducing the amount of cleaning work.

[0041] Optionally, the rotational speeds of the first cutter 2 and the second cutter 3 can be adjusted according to actual processing requirements. For example, when rapid granulation is required, the rotational speed of the first cutter 2 can be increased; or, when the particle size needs to be reduced, the rotational speed of the second cutter 3 can be increased. In this embodiment, the rotational speed range of the second cutter 3 is 1 r / min to 700 r / min, and the rotational speed range of the second cutter 3 is 10 r / min to 2000 r / min. Specifically, when the rotational speed of the second cutter 3 is around 2000 r / min and the rotational speed of the first cutter 2 is around 700 r / min, the granulation effect of the coating granulation equipment 100 is weakened, resulting in a single particle outer wall coating with liquid asphalt, achieving room temperature coating functionality. When the rotational speed of the second cutter 3 is around 1500 r / min and the rotational speed of the first cutter 2 is around 500 r / min, room temperature granulation of coke particles and liquid asphalt can be achieved.

[0042] Optionally, the inner wall of the housing 1 may be coated or polished to reduce the adhesion of liquid asphalt and coke particles.

[0043] Optionally, the dimensions of the grinding blade 21 and the shovel 22 can be adjusted according to the dimensions of the cavity 11. In this embodiment, the length of the grinding blade 21 and the shovel 22 ranges from 100 mm to 150 mm, and the bottom wall 14 is circular with a radius of 150 mm. Preferably, the length of the grinding blade 21 and the shovel 22 can be set to 120 mm, leaving a certain margin to ensure that the grinding blade 21 and the shovel 22 do not interfere with the side wall 13 after being installed in the cavity 11. It is understood that the side of the grinding blade 21 and the shovel 22 furthest from the rotating shaft, closer to the side wall 13, has a longer length and a greater linear velocity, thereby generating a greater grinding pressure on the mixture, making the volatile components more easily volatilized.

[0044] In one implementation, please refer to Figure 5 and Figure 6 The grinding blade 21 has a grinding surface 212, which is curved and protrudes towards the bottom wall 14. Along the rotation direction of the grinding blade 21, the grinding surface 212 has a first side 2121 and a second side 2122 that are arranged opposite to each other, and the first side 2121 is located in front of the second side 2122. The distance between the first side 2121 and the bottom wall 14 is greater than the distance between the second side 2122 and the bottom wall 14. A gap is formed between the grinding surface 212 and the bottom wall 14.

[0045] In this embodiment, the grinding blade 21 has a grinding surface 212, which is an arc surface that protrudes from the bottom wall 14. During the rotation of the grinding blade 21, the mixture first passes through the first side 2121 and enters between the grinding surface 212 and the bottom wall 14. As the rotation continues, the second side 2122 approaches the mixture. Since the distance between the first side 2121 and the bottom wall 14 is greater than the distance between the second side 2122 and the bottom wall 14, the grinding surface 212 will exert a grinding pressure on the mixture, causing the liquid asphalt to collide and rub against the bottom wall 14 and between the liquid asphalt molecules, thereby generating instantaneous high temperature, causing the volatiles to evaporate and be discharged from the vent 122.

[0046] Optionally, the number of grinding blades 21 can be adjusted according to the size of the cavity 11 and processing requirements. Increasing the number of grinding blades 21 can improve the grinding efficiency.

[0047] Alternatively, the grinding blade 21 can be a roller. In this case, the roller can rotate around the central axis of the cavity 11, but the roller itself cannot rotate. The surface of the roller is used for grinding.

[0048] In one implementation, please refer to Figure 6Each grinding blade 21 also includes multiple grinding protrusions 213, which are arranged side by side on the second side 2122.

[0049] In this embodiment, multiple crushing protrusions 213 are arranged side by side on the second side 2122. The crushing protrusions 213 can reduce the space between the second side 2122 and the bottom wall 14, thereby increasing the pressure on the mixture when it passes between the second side 2122 and the bottom wall 14, increasing the friction effect, generating a higher instantaneous temperature, and making the volatiles more likely to evaporate.

[0050] Optionally, the compaction protrusions 213 can be designed as circular, square, or triangular to adapt to different processing requirements. Simultaneously, the number and spacing of the compaction protrusions 213 can be optimized according to the characteristics of the liquid asphalt and coke particles to ensure the best granulation effect. In this embodiment, the compaction protrusions 213 are triangular, and each roller 21 has four compaction protrusions 213, which are equally spaced on the second side 2122.

[0051] Alternatively, a wear-resistant coating or an anti-stick coating may be added to the surface of the rolling protrusion 213 to extend the service life of the rolling protrusion 213.

[0052] In one implementation, please refer to Figure 5 and Figure 6 The distance between the second side 2122 and the bottom wall 14 ranges from 3 mm to 5 mm.

[0053] In this embodiment, the distance between the second side 2122 and the bottom wall 14 needs to be set between 3 mm and 5 mm. This ensures that the grinding blade 21 can sufficiently crush the mixture during rotation, guaranteeing the volatilization of volatiles and achieving granulation. If the distance is too small, the coke particles in the mixture may not be able to pass through the grinding blade 21, failing to achieve the crushing effect. If the distance is too large, the crushing effect may be weakened, failing to generate sufficient instantaneous high temperature, and the volatiles may not be fully volatilized.

[0054] In one implementation, please refer to Figure 5 and Figure 6 The shovel 22 has a shovel-lifting side surface 222 and a shovel-lifting bottom surface 221 connected to each other. Along the rotation direction of the shovel 22, the distance between the front side of the shovel-lifting side surface 222 and the bottom wall 14 is smaller than the distance between the rear side of the shovel-lifting side surface 222 and the bottom wall 14. The shovel-lifting bottom surface 221 is connected to the front side of the shovel-lifting side surface 222, and the shovel-lifting bottom surface 221 is positioned opposite the bottom wall 14, with a gap between the shovel-lifting bottom surface 221 and the bottom wall 14.

[0055] In this embodiment, each shovel 22 has a shovel side 222 and a shovel bottom 221. The side where the shovel side 222 and the shovel bottom 221 intersect can shovel up the liquid asphalt and coke particles adhering to the bottom wall 14, so that the shoveled coke particles roll along the shovel side 222, thereby leaving the first cutter 2 and entering the second cutter 3 for stirring. This can improve the utilization rate of liquid asphalt and coke particles and avoid resource waste.

[0056] Understandably, the scooping side 222 guides the coke particles towards the top wall 12 during rotation, allowing them to leave the first cutter 2. Therefore, the scooping side 222 needs to be positioned such that the distance between its front side and the bottom wall 14 is smaller than the distance between its rear side and the bottom wall 14 along the rotation direction of the scooping cutter 22, thus achieving a guiding effect and allowing the adhered coke particles to leave the first cutter along the scooping side 222. The specific shape of the scooping side 222 is not limited here; it can be a sloping plane or a concave curved surface. In this embodiment, the scooping side 222 is an inclined plane, which guides the coke particles to quickly leave the first cutter 2. Simultaneously, the scooped-up adhered coke particles will rotate and rub upwards at high speed along the inner wall of the housing 1, generating instantaneous high temperatures that cause volatiles to evaporate, and the coke particles to focus together, forming large particles.

[0057] Optionally, the number of scrapers 22 can be adjusted according to the size of the cavity 11 and processing requirements. Increasing the number of scrapers 22 can improve the scraping efficiency.

[0058] In one implementation, please refer to Figure 5 and Figure 6 The shovel includes a first shovel portion 224 and a second shovel portion 225 connected to each other. Both the first shovel portion 224 and the second shovel portion 225 are set at an angle to the bottom wall 14, and the first shovel portion 224 and the second shovel portion 225 are also set at an angle to each other. Along the rotation direction of the shovel 22, the front sides of the first shovel portion 224 and the second shovel portion 225 cooperate to form a shovel side surface 222, and the sides of the first shovel portion 224 and the second shovel portion 225 facing the bottom wall 14 cooperate to form a shovel bottom surface 221.

[0059] In this embodiment, by setting the first scooping part 224 and the second scooping part 225, it is equivalent to using two inclined planes to scoop up the adhesive on the bottom wall 14. The included angle of the two inclined planes makes the direction of the force on the adhesive when it is scooped up steeper, increasing the vertical velocity component, thereby making the adhesive thrown up higher, which is convenient for the second cutter 3 to cut.

[0060] In one implementation, please refer to Figure 6 The shovel 22 also includes multiple shovel protrusions 223, which are arranged side by side on the bottom surface 221 of the shovel.

[0061] In this embodiment, when the shovel protrusion 223 comes into contact with the liquid asphalt and coke particles adhering to the bottom wall 14, it can cut the adhering materials together and push them in all directions, thereby reducing the suction between these adhering materials and the bottom wall 14, making it easier for the shovel blade 22 to shovel them up.

[0062] Optionally, the shovel protrusions 223 can be designed as circular, square, or triangular to adapt to different processing requirements. Simultaneously, the number and spacing of the shovel protrusions 223 can be optimized according to the characteristics of liquid asphalt and coke particles to ensure the best cleaning effect. In this embodiment, each shovel blade 22 has three shovel protrusions 223, which are equally spaced on the shovel bottom surface 221.

[0063] Preferably, the scooping protrusion 223 is triangular, and along the rotation direction of the scooping blade 22, one corner of the triangle is located in front of the scooping protrusion 223. During the rotation of the scooping protrusion 223, the mixture can move along the two sides adjacent to this corner, thereby cutting away the mixture adhering to the bottom wall 14 and pushing it in all directions, so that the scooping blade 22 can scoop up the mixture.

[0064] Similarly, a wear-resistant coating or an anti-stick coating can be added to the surface of the scooping protrusion 223 to extend its service life.

[0065] In one implementation, please refer to Figure 5 and Figure 6 Multiple grinding blades 21 and multiple shovels 22 are provided, and the multiple grinding blades 21 and multiple shovels 22 are arranged at intervals along the rotation direction of the first cutter 2. Among them, there is at least one shovel 22 between two adjacent grinding blades 21, and at least one grinding blade 21 between two adjacent shovels 22.

[0066] Understandably, for a certain area of ​​the bottom wall 14, after each roller 21 has finished rolling, the corresponding shovel 22 will immediately perform a shoveling operation. After each shovel 22 has finished shoveling, the subsequent roller 21 will start a new rolling operation, thereby ensuring that the liquid asphalt and coke particles are fully rolled and shoveled during the granulation process.

[0067] Optionally, along the rotation direction of the first cutter 2, a shovel 22 is provided between two adjacent grinding blades 21. When a grinding blade 21 is provided between two adjacent shovels 22, the grinding blades 21 and shovels 22 are staggered, thereby ensuring that the grinding blades 21 and shovels 22 can respectively perform grinding and shoveling operations on the mixture in a timely manner. Optionally, multiple shovels 22 can be provided between two adjacent grinding blades 21, thereby enabling timely cleaning of the mixture after grinding by the grinding blades 21, preventing excessive accumulation on the bottom wall 14, and reducing the amount of cleaning work after processing. Optionally, multiple grinding blades 21 can be provided between two adjacent shovels 22. Multiple grinding blades 21 can increase the number of grinding operations per unit time, allowing volatile components to evaporate faster, thereby reducing waiting time.

[0068] In this embodiment, both the grinding blade 21 and the shovel blade 22 are included in pairs. The two grinding blades 21 are arranged opposite each other along a first direction, and the two shovel blades 22 are arranged opposite each other along a second direction, so that the grinding blades 21 and shovel blades 22 are staggered along the rotation direction of the second tool 2. The first direction and the second direction are arranged at an angle.

[0069] Optionally, the angle between the first direction and the second direction can be adjusted according to the actual situation, and is not limited here, but it is necessary to ensure that there is sufficient distance between the grinding blade 21 and the shovel blade 22 to avoid mutual interference between the two.

[0070] Optionally, the two grinding blades 21 and the two shovel blades 22 are integrally formed to enhance the structural strength of the first blade 2.

[0071] In one implementation, please refer to Figure 1 and Figure 2 The coating granulation equipment 100 also includes a base 5, and the first cutter 2 also includes a rotating drive component 23 and a transmission assembly. The rotating drive component 23 and the housing 1 are arranged side by side on the base 5. One side of the transmission assembly is connected to the rotating drive component 23, and the other side of the transmission assembly is connected to the grinding blade 21 and the shovel blade 22.

[0072] In this embodiment, the transmission assembly includes a transmission component, a first bearing housing 24, and a first transmission shaft. The first bearing housing 24 and the rotation drive component 23 are arranged side-by-side on the base 5, and the housing 1 is located on top of the first bearing housing 24. The first transmission shaft is installed inside the first bearing housing 24, with one end extending into the cavity 11 and connected to the integrally formed grinding blade 21 and shovel blade 22 via a key. The other end is connected to the rotation drive component 23 via the transmission component. The rotation drive component 23 drives the first transmission shaft to rotate via the transmission component, thereby causing the grinding blade 21 and shovel blade 22 to rotate around the axis of the transmission shaft. Understandably, with the support of the base 5 and the first bearing housing 24, the first transmission shaft can rotate stably, ensuring the synchronous rotation of the grinding blade 21 and shovel blade 22. Furthermore, by arranging the first bearing housing 24 and the rotation drive component 23 side-by-side, the height of the coating granulation equipment 100 can be reduced, thereby ensuring the stability of the grinding blade 21 and shovel blade 22 during rotation.

[0073] Optionally, the rotation drive 23 can be a servo motor or a stepper motor to achieve precise speed control and position adjustment. Optionally, the transmission component can be a gear drive or a belt drive, which can be adjusted according to actual needs.

[0074] In one implementation, please refer to Figure 3 and Figure 4 The second cutter 3 includes a stirring drive assembly 31 and side blades 32. The stirring drive assembly 31 is disposed on the side wall 13 of the housing 1, and the output shaft of the stirring drive assembly 31 extends into the cavity 11. The side blades 32 include multiple side blades, which are sequentially disposed on the output shaft along the extension direction of the output shaft. The stirring drive assembly 31 drives the multiple side blades 32 to rotate synchronously around the output shaft.

[0075] In this embodiment, the second cutter 3 includes a stirring drive assembly 31 and a plurality of side cutters 32. The stirring drive assembly 31 is mounted on the side wall 13 of the housing 1, and the output shaft of the stirring drive assembly 31 extends into the cavity 11. Along the extension direction of the output shaft, the plurality of side cutters 32 are sequentially arranged on the output shaft. The stirring drive assembly 31 drives the plurality of side cutters 32 to rotate synchronously, thereby realizing the stirring and dispersing function of liquid asphalt and coke particles.

[0076] In this embodiment, the distance between the side blade 32 and the bottom wall 14 ranges from 20 mm to 30 mm, allowing the side blade 32 to receive and break up the mixture scooped up by the shovel 22. If the distance is too high, the mixture may not be received; if the distance is too low, it may interfere with the rotation of the first blade 2.

[0077] Optionally, the number of side blades 32 can be adjusted according to the size of the cavity 11 and processing requirements. For example, in a larger cavity 11, the number of side blades 32 can be increased to improve the efficiency of stirring and dispersing.

[0078] In one implementation, please refer to Figure 4 The multiple side cutters 32 include a first blade 321 and a second blade 322 that are coaxially rotatable. The first blade 321 and the second blade 322 are staggered along the extension direction of the output shaft of the second cutter 3, and the extension direction of the first blade 321 and the extension direction of the second blade 322 are set at an angle.

[0079] In this embodiment, the staggered arrangement of the first blade 321 and the second blade 322 ensures that the liquid asphalt and coke particles are fully mixed and dispersed during the stirring process. The perpendicular arrangement of the first blade 321 and the second blade 322 ensures stability during rotation. Simultaneously, the chamfered edges of the first blade 321 and the second blade 322 provide a smooth transition, preventing the edges from cutting the coke particles during rotation and ensuring that the first blade 321 and the second blade 322 only perform the functions of stirring and dispersing during rotation.

The second drive shaft is rotatably mounted on the second bearing housing 313. The two ends of the coupling 312 are respectively connected to the output shaft of the stirring drive component 311 and the second drive shaft. At this time, the side blade 32 is mounted on the second drive shaft. It can be understood that through the cooperation of the second bearing housing 313 and the coupling 312, the second drive shaft can rotate stably, ensuring the synchronous rotation of the side blade 32.

[0083] In this embodiment, the stirring drive assembly 31 includes a stirring drive component 311, a coupling 312, a second bearing housing 313, and a second drive shaft. The second drive shaft is installed inside the second bearing housing 313, and the two ends of the coupling 312 are respectively connected to the output shaft of the stirring drive component 311 and the second drive shaft.

[0084] Optionally, the stirring drive 311 can be a servo motor or a stepper motor to achieve precise speed control and position adjustment. Meanwhile, the coupling 312 can be a flexible coupling 312 or a rigid coupling 312, which can be adjusted according to actual needs and is not limited here.

[0085] In one implementation, please refer to Figure 4 The second tool 3 also includes a locking mechanism 33, which is used to limit the side tool 32 and prevent the side tool 32 from deviating along the extension direction of the output shaft.

[0086] In this embodiment, the second cutter 3 further includes a locking mechanism 33, which includes a locking head and a pin. The locking head is sleeved on the second drive shaft and abuts against one side of the side cutter 32. The pin passes through the pin hole of the locking head and the second drive shaft to fix the locking head, thereby limiting the side cutter 32 and preventing the side cutter 32 from deviating along the extension direction of the output shaft during the stirring process.

[0087] Optionally, the locking mechanism 33 can also be locked with a nut. The locking mechanism 33 is threadedly connected to the second drive shaft, so that the side blade 32 can be directly limited by the locking mechanism 33.
