[0002] As the core equipment for mixing and dispersing highly viscous materials, vacuum high-speed dispersing machines are widely used in fields such as new energy battery slurries, electronic slurries, and special coatings; traditional equipment combines a low-speed stirring paddle and a high-speed dispersing disk, supplemented by a vacuum environment, to achieve efficient mixing of powders and liquids. However, with the improvement of battery energy density and the application of new binders, existing equipment gradually shows some deficiencies in terms of mixing efficiency and process stability.

[0003] Existing equipment adopts a fixed-inclination stirring paddle and an independent dispersing disk structure. The low-speed rotation of the stirring paddle only achieves macroscopic circulation, while the high-speed shear coverage area of the dispersing disk is limited, resulting in easy generation of mixing dead angles for high-viscosity substances; especially for nano-scale active materials, uneven traditional shear force distribution easily causes particle secondary aggregation, requiring repeated dispersion, which increases the energy consumption of the equipment.

[0015] A method for using a vacuum high-speed disperser, the method comprising the following steps: S1: Add the material to be processed into the aggregation cylinder inside the sealing cover through the conical feeding pipe. Start the hydraulic rod to lower the sealing cover and make it fit tightly with the top of the thermal insulation shell. Then connect to an external vacuum pump through the evacuation pipe to perform a vacuum treatment on the inside of the inner tank to prevent the generation of bubbles during the stirring process; S2: Adjust the opening angle of the stirring frame of the mixing mechanism according to the viscosity of the material. For high-viscosity materials, control the electric telescopic rod to extend and push the sliding plate downward, and drive the stirring frame to open to 60° through the adjusting rod; for low-viscosity materials, contract the electric telescopic rod to close the stirring frame to 30°. At the same time, the shearing balls are self-adaptively expanded under the action of centrifugal force to enhance the shearing effect; S3: Then start the servo motor to drive the main shaft rod to rotate, and drive the stirring frame and the expansion assembly to rotate at high speed synchronously through the rotating rod to complete the efficient mixing of the material. At the same time, the scraping plate rotates with the rotating rod to automatically clean the residual material on the inner wall of the inner tank; S4: After the mixing is completed, turn off the vacuum pump and restore the normal pressure environment. Rotate the three-piece discharge ball valve to an opening of 45° to smoothly discharge the slurry. Then release the thermal insulation shell through the limiting buffer mechanism and the tightening mechanism, and slide it out along the bracket guide rail to complete the entire processing process.

[0016] Compared with the prior art, the above technical solution provided by the present invention has at least the following beneficial effects: (1) This solution is provided with a servo motor, a cleaning mechanism, and a mixing mechanism. When in use, the electric telescopic rod is adjusted according to the viscosity parameters of the material. For example, when processing high-viscosity slurry, the electric telescopic rod is extended to push the slide plate downward, and the stirring frame is opened outward to an angle of 60° through the adjustment rod, thereby increasing the shear area; when processing low-viscosity materials, the electric telescopic rod is retracted, the slide plate moves upward, and the stirring frame is retracted to an angle of 30° to expand the mixing range; this design allows the angle of the stirring frame to be adjusted steplessly to adapt to different material characteristics, effectively reducing mixing dead angles and preventing secondary agglomeration of nanoparticles; at the same time, the same driving force source, that is, the rotating rod driven by the servo motor, is not only used for material mixing, but also drives the scraper plate to automatically clean the inner wall of the storage component, reducing the need for manual intervention and improving production efficiency.

[0017] (2) By setting up an extension component, the servo motor drives the rotating rod to drive the stirring frame to rotate at high speed in the inner tank. At this time, the shear ball moves outward due to the centrifugal force and drives the ring to slide along the support rod through the steel rope, thereby expanding the shear area. This solves the problem that the expansion range of the traditional shear component is fixed and cannot be dynamically adjusted according to the material characteristics and centrifugal force, resulting in insufficient shear force when processing high-viscosity materials and excessive shearing when processing low-viscosity materials.

[0018] (3) By setting a limit buffer mechanism and a tightening mechanism, during high-speed stirring, if the insulation shell shakes and squeezes the buffer plate, the spring telescopic rod will be further compressed and push the T-shaped slide plate to slide along the limit rod toward the vertical plate. This action will drive the toothed plates on both sides of the T-shaped slide plate to move synchronously, thereby driving the gear to rotate. Since the gear is fixedly connected to the first vertical pole, the first vertical pole will also rotate accordingly, pulling the first tightening belt and the second tightening belt to automatically tighten. Through this design, even if the insulation shell shakes slightly during stirring, the system can respond quickly and automatically adjust the tightening force to ensure that it is always in a stable state. At the same time, the existence of the second vertical pole and the third vertical pole enables the pressure to be evenly distributed, avoiding the risk of local overload.

[0022] As shown in the figure, in order to clearly implement the structure of the embodiments of the present invention, specific structures and devices are marked in the figure. However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device, and environment. Those of ordinary skill in the art can adjust or modify these devices and environments according to specific needs. Detailed implementation manners

[0023] The following describes in detail a vacuum high-speed disperser and its usage method provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods for implementation; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present invention.

[0024] As Figures 1 to 10 shown, the embodiments of the present invention provide a vacuum high-speed disperser and its usage method, including a processing table 1 and a lifting table 2. A top plate 3 is fixedly connected to the top of the lifting table 2. A storage assembly 9 for storing materials is arranged on the upper surface of the processing table 1. At one end of the bottom of the top plate 3, a sealing assembly 13 for sealing and evacuating the storage assembly 9 is arranged. The sealing assembly 13 includes a sealing cover 131; a cleaning mechanism 17 and a mixing mechanism 18 are arranged at the inner bottom of the sealing cover 131. The cleaning mechanism 17 includes a rotating rod 172 and a scraping wall plate 174. At one end of the bottom of the top plate 3, a servo motor 16 and a main spindle rod 161 for driving the cleaning mechanism 17 and the mixing mechanism 18 are arranged; Among them, the mixing mechanism 18 includes a fixed socket 181 fixedly connected to the outer circumferential surface of the bottom of the rotating rod 172. A sliding plate 182 is slidably connected to the middle of the outer circumferential surface of the rotating rod 172. A fixing plate 185 is fixedly connected to the upper end of the outer circumferential surface of the rotating rod 172, and an electric telescopic rod 186 for adjusting the position of the sliding plate 182 is fixedly connected to the bottom of the fixing plate 185. Stirring frames 183 are hinged on both sides of the outer circumferential surface of the fixed socket 181. Adjusting rods 184 for pulling the stirring frames 183 are hinged on both sides of the outer surface of the sliding plate 182. An expansion assembly 187 for promoting the mixing of materials is arranged inside the stirring frame 183; The position of the sliding plate 182 is changed by using the electric telescopic rod 186, and the opening angle of the stirring frame 183 is adjusted in cooperation with the adjusting rod 184 to meet the shearing requirements of materials with different viscosities; and the driving force provided by the servo motor 16 is used to drive the rotating rod 172 to drive the scraping wall plate 174 to rotate, so as to clean the storage assembly 9, and the same driving force is used to make the stirring frame 183 rotate at a high speed to complete the mixing and stirring of the materials.

[0025] To solve the problems that the stirring paddle angle of the traditional disperser is fixed and cannot adapt to the shearing requirements of materials with different viscosities, resulting in many mixing dead corners of high-viscosity materials and secondary agglomeration of nanoparticles, as well as the low efficiency caused by the need for separate operations for mixing and cleaning, the above technical solution is now adopted to solve the problem. The above technical solution mainly consists of a servo motor 16, a cleaning mechanism 17, and a mixing mechanism 18. When processing materials inside the storage component 9, first, the electric telescopic rod 186 is adjusted according to the viscosity parameters of the materials. For example, when processing high-viscosity slurries, the electric telescopic rod 186 extends, pushing the slide plate 182 downward, and through the adjusting rod 184, the stirring frame 183 is opened outward to a 60° angle, thereby increasing the shearing area; while when processing low-viscosity materials, the electric telescopic rod 186 contracts, the slide plate 182 moves upward, and the stirring frame 183 is closed to a 30° angle to expand the mixing range. This design allows the angle of the stirring frame 183 to be adjusted steplessly, adapting to different material characteristics, effectively reducing mixing dead corners and preventing secondary agglomeration of nanoparticles. After the angle of the stirring frame 183 is adjusted, the servo motor 16 is started to drive the main shaft rod 161 to rotate, and then drive the rotating rod 172 to rotate at a high speed, so that the stirring frame 183 and the expansion component 187 rotate synchronously. During this process, the sliding fit between the fixed socket 181 and the slide plate 182 ensures the transmission stability of the stirring frame 183 during angle adjustment. To further improve the equipment performance, during the stirring process, considering that the temperature rise may cause high-viscosity slurries to adsorb on the inner wall of the storage component 9, affecting the finished product effect, in this solution, the rotating rod 172 driven by the same driving power source - that is, the servo motor 16 is not only used for material mixing, but also drives the scraping plate 174 to automatically clean the inner wall of the storage component 9, reducing the need for manual intervention and improving production efficiency. In summary, through the above technical solution, the dynamic adjustment of the angle of the stirring frame 183 is realized, which can better adapt to materials with various viscosities, significantly improve the dispersion uniformity of nanomaterials, and integrate the cleaning function, greatly improving the efficiency of the entire process flow and the quality of the finished product.

[0026] As Figure 1 , Figure 2 , Figure 3 shown, the lifting platform 2 is fixedly installed on one side of the upper surface of the processing table 1. A support plate 4 is slidably connected to one side inside the processing table 1. One side of the bottom of the top plate 3 close to the lifting platform 2 is provided with a hydraulic rod 5. The bottom of the hydraulic rod 5 is fixedly connected to a bracket 6. The storage component 9 includes a heat preservation outer shell 91 placed on the upper surface of the bracket 6. A heating pipe is fixedly connected around the inner wall of the heat preservation outer shell 91. An inner tank 92 is fixedly connected to the middle of the inside of the heat preservation outer shell 91. A three-piece type discharge ball valve is arranged at the bottom of the outer cylindrical surface of the heat preservation outer shell 91. Two second fixed sleeves 93 are fixedly connected to both sides of the middle of the outer cylindrical surface of the heat preservation outer shell 91. A convex base 94 is fixedly connected to the bottom of the heat preservation outer shell 91, and self-locking universal wheels are installed at the four corners of the bottom of the convex base 94.

[0027] As Figure 1 、 Figure 2 shown, the bracket 6 is concave-shaped, and the recessed areas on both sides of the convex base 94 are slidably connected to the bottom of the bracket 6. The support plate 4 is located at the bottom of the convex base 94. The bracket 6 and the support plate 4 cooperate together to limit and fix the heat preservation outer shell 91. Long strip blocks are fixedly connected to both sides of the upper surface of the processing table 1, and the gaps formed between adjacent long strip blocks are used to place the support plate 4.

[0028] To avoid problems such as the offset of the inner tank 92 during the processing of the traditional storage component 9, the delay in the lifting and lowering of the hydraulic system in a low-temperature environment, and cross-contamination caused by material residue, this solution effectively improves the stability of the equipment operation and the adaptability to a low-temperature environment through the sliding limit cooperation design of the convex base 94 and the bracket 6, combined with the constant temperature control function of the heating tube. The specific operation process is as follows: First, before pushing the heat preservation outer shell 91 into the equipment, the operator can hold the handrail provided on its outer side to unlock the self-locking universal wheels installed at the bottom of the heat preservation outer shell 91, facilitating flexible movement. Subsequently, align the recessed areas on both sides of the convex base 94 with the guide rail structure on the bracket 6 and slide smoothly along the guiding direction until it is completely pushed into the limit position. At this time, the support plate 4 can slide into its limit groove from the side of the processing table 1 and act together with the bracket 6 to support and limit the convex base 94, ensuring that the inner tank 92 will not be displaced due to vibration or shear force during the stirring and mixing process, thereby significantly improving the stability and safety of the entire processing process. To address the impact of a low-temperature environment on the hydraulic system and prevent the performance of the slurry from deteriorating due to temperature changes, a circumferential heating tube is provided on the inner wall of the heat preservation outer shell 91. During the slurry processing, the heating tube can maintain the temperature inside the inner tank 92 within the set range, not only ensuring the rheological properties of the slurry but also avoiding problems such as an increase in the viscosity of the hydraulic oil and a lag in the response of the hydraulic cylinder due to too low temperature, thereby improving the working efficiency and reliability of the equipment in a low-temperature environment. In addition, after completing the mixing process, by rotating the three-piece discharge ball valve to an opening of 45°, the slurry can be discharged smoothly. This three-piece ball valve structure has higher sealing performance and less dead space compared to traditional valves, can significantly reduce the slurry residue amount, effectively avoid cross-contamination between different batches of materials, and improve the cleaning efficiency and production continuity.

[0029] As Figure 8 、 Figure 10As shown in the figure, the expansion component 187 includes a plurality of support rods 1871 arranged linearly and fixedly connected to the inside of the stirring frame 183. The support rods 1871 are equidistantly distributed along the axis direction of the stirring frame 183 and are perpendicular to the rotation plane of the stirring frame 183, forming a rigid guiding support structure. Inside the stirring frame 183, there are also collar rings 1872 sleeved on the outer cylindrical surface of the support rods 1871 at intervals. A steel cable 1873 is fixedly connected to the bottom of the collar ring 1872. Each collar ring 1872 is fixedly connected to a shear ball 1874 through the steel cable 1873. The shear ball 1874 expands outward under the action of centrifugal force when the stirring frame 183 rotates at a high speed. The length of the steel cable 1873 matches the spacing of the support rods 1871, restricting the maximum expansion radius of the shear ball 1874 and enabling it to generate multi-directional dynamic shear forces within a preset range.

[0030] To solve the problems that the expansion range of the traditional shear component is fixed and cannot be dynamically adjusted according to the material properties and centrifugal force, resulting in insufficient shear force when processing high-viscosity materials and excessive shear when processing low-viscosity materials, the shear ball 1874 is now realized to expand adaptively through the centrifugal force-driven expansion component 187. Specifically, driven by the servo motor 16, the rotating rod 172 drives the stirring frame 183 to rotate at a high speed in the inner tank 92. At this time, the shear ball 1874 moves outward under the action of centrifugal force and drives the collar ring 1872 to slide along the direction of the support rod 1871 through the steel cable 1873, thereby realizing the expansion of the shear area. Among them, the length of the steel cable 1873 matches the spacing between the support rods 1871, restricting the maximum expansion radius of the shear ball 1874 not to exceed 60 mm to prevent structural deformation or mechanical failure caused by excessive expansion. For example, when processing high-viscosity materials, the shear ball 1874 expands to the maximum radius of 60 mm under the action of centrifugal force, and the generated local shear stress is greater than 500 Pa, which is sufficient to effectively break the agglomerated particles in the slurry and improve the dispersion effect. When processing low-viscosity materials, the shear ball 1874 is less affected by centrifugal force, and the expansion radius automatically shrinks to about 30 mm, and the corresponding shear stress is maintained at about 200 Pa, avoiding unnecessary crushing of the nanoparticles and protecting the structural integrity of the material. During the entire mixing process, the expansion range of the shear ball 1874 can be adjusted adaptively according to the material viscosity and the magnitude of the centrifugal force, not only improving the dispersion efficiency of the nanoparticles, but also significantly improving the particle size distribution uniformity of the final product and enhancing the slurry quality and process stability.

The output end of the servo motor 16 is fixedly connected to a main shaft rod 161.

On both sides of the threaded rod 144, card sleeve rods 143 fixedly connected to the gathering cylinder 141 are arranged. A clamping groove adapted to the receiving rod 135 is arranged inside the card sleeve rod 143. A locking sleeve 15 is also sleeved on the outer circular surfaces of the card sleeve rod 143 and the receiving rod 135 together. One end of the stirring rod 145 is fixedly connected to a scraping plate 146 for cleaning the residues on the inner wall of the gathering cylinder 141. The bottom of the stirring rod 145 is fixedly connected to a receiving pipe 147.

[0033] As Figure 7 , Figure 10 shown in the figure, the cleaning mechanism 17 further includes a receiving clamping rod 171 fixedly connected to the top of the rotating rod 172. The receiving clamping rod 171 is clamped inside the receiving pipe 147 and becomes a rigid connection through the locking sleeve 15; support plates 173 are fixedly connected to the top end and the bottom end of the outer circular surface of the rotating rod 172. Scraping plates 174 are fixedly connected to the outer sides of the support plates 173. Fixing rods 175 arranged in a linear array are fixedly connected to the inner sides of the scraping plates 174.

[0034] To avoid the generation of bubbles during the slurry stirring process, which may affect the quality of the finished slurry, and to prevent the problem of extended main mixing time caused by insufficient premixing, an integrated design of the sealing cover 131 and the aggregation mechanism 14 is now adopted to achieve an efficient premixing process in a vacuum environment. The specific operation steps are as follows: First, start the hydraulic rod 5, contract it to drive the sealing cover 131 to descend, and closely fit it with the top of the heat preservation shell 91 through the silicone rubber sealing ring to ensure that the entire system is in a good sealed state. Before starting the processing, accurately insert the ferrule rod 143 into the receiving rod 135 and fix it with the locking sleeve 15 to ensure a firm connection. At this time, the circulation pipe 142 is respectively inserted into the conical feeding pipe 134, and at the same time, the threaded rod 144 contacts the main shaft rod 161, and the connection between the threaded rod 144 and the main shaft rod 161 is strengthened by rotating the locking sleeve 15 to ensure that when the servo motor 16 drives the main shaft rod 161 to rotate, the locking sleeve 15 can also rotate synchronously. In this setting, the aggregation cylinder 141 is in a relatively fixed position. Since the bottom of the threaded rod 144 is fixedly connected to the stirring rod 145, and the bottom of the stirring rod 145 is connected to the receiving pipe 147, when the locking sleeve 15 rotates, the stirring rod 145 and the receiving pipe 147 also rotate accordingly. After the material enters the aggregation cylinder 141 through the conical feeding pipe 134, the threaded rod 144 drives the stirring rod 145 to rotate in the aggregation cylinder 141 to preliminarily mix the slurry. During this process, the stirring rod 145 drives the scraper 146 to scrape the residual slurry on the cylinder wall to reduce waste. The preliminarily mixed material is smoothly introduced into the inner tank 92 in the form of laminar flow through the circulation pipe 142, effectively avoiding the local accumulation phenomenon caused by eddy currents. At the same time, because the receiving pipe 147 is fixedly connected to the receiving clamping rod 171 through the locking sleeve 15, during the preliminary mixing process, the slurry falling into the inner tank 92 will be further stirred by the secondary stirring assembly composed of the support plate 173, the wall scraping plate 174 and the fixing rod 175. At the same time, the wall scraping plate 174 will clean the slurry on the inner wall of the inner tank 92 to reduce the residual amount and improve the uniformity of the slurry. Finally, to maintain the vacuum environment of the system, an external vacuum pump is connected through the evacuation pipe 133 to discharge the air in the inner tank 92, and the internal pressure is monitored in real time by a peripheral pressure sensor to ensure that the entire mixing process is carried out under ideal vacuum conditions. This not only improves the quality of the finished slurry but also optimizes the overall process flow efficiency.

[0035] As Figure 1 , Figure 3 , Figure 4 , Figure 5As shown, a vertical plate 7 is fixedly connected to the inner side of the upper surface of the bracket 6. A limit buffer mechanism 8 for limiting the thermal insulation outer shell 91 is arranged on the outer side of the vertical plate 7. The limit buffer mechanism 8 includes a U-shaped frame 81 fixedly connected to the outer side of the vertical plate 7. An arc plate 82 is fixedly connected to the open end of the U-shaped frame 81. First fixing sleeves 83 are fixedly connected to the outer sides of both ends of the arc plate 82. A locking rod 84 is threadedly connected inside the first fixing sleeve 83, and the locking rod 84 passes through the first fixing sleeve 83 and inserts into the second fixing sleeve 93 to further limit the thermal insulation outer shell 91. A buffer plate 86 is arranged on the inner side of the arc plate 82, and spring telescopic rods 85 fixedly connected to the arc plate 82 are arranged at both ends of the inner side of the buffer plate 86.

[0036] As Figure 1 , Figure 3 , Figure 4 , Figure 5 shown, a tightening mechanism 10 for preventing the thermal insulation outer shell 91 from shaking is arranged on the inner side of the U-shaped frame 81. The tightening mechanism 10 includes an H-shaped plate 101 fixedly connected to the inner side of the U-shaped frame 81. A limit rod 102 is fixedly connected to the middle of one side of the outer surface of the H-shaped plate 101. A T-shaped sliding plate 103 is slidably connected to the middle of the inner part of the arc plate 82, and the limit rod 102 inserts into the inner part of the T-shaped sliding plate 103 to limit and support the T-shaped sliding plate 103. Tooth plates 104 are fixedly connected to both ends of one side of the outer surface of the T-shaped sliding plate 103. The middle horizontal plate of the T-shaped sliding plate 103 passes through the arc plate 82 and is fixedly connected to the buffer plate 86. Auxiliary plates 105 are fixedly connected to the four ends of the H-shaped plate 101. A limit seat 106 is fixedly connected to one side of the outer surface of the auxiliary plate 105. A first vertical rod 107 is rotatably connected to the inside of the limit seat 106. Gears 108 are fixedly connected to both ends of the outer circular surface of the first vertical rod 107, and the gears 108 are meshed with the tooth plates 104. A second vertical rod 109 and a third vertical rod 110 are fixedly connected in sequence to the bottom of the auxiliary plate 105 near one side of the arc plate 82. A first tightening belt 11 and a second tightening belt 12 are wound around the outer circular surface of the thermal insulation outer shell 91. One ends of the first tightening belt 11 and the second tightening belt 12 pass through the second vertical rod 109 and the third vertical rod 110 in sequence and are fixedly connected to the first vertical rod 107 to facilitate the tightening operation.

[0037] To ensure that the storage component 9 for storing materials has sufficient stability during the stirring process and avoid affecting the normal mixing of the slurry due to the offset of the outer shell, the above technical solution is now adopted to solve the problem. The above technical solution mainly consists of a limit buffer mechanism 8 and a tightening mechanism 10. When in use, first, the thermal insulation outer shell 91 is pushed and placed on the bracket 6. At this time, the thermal insulation outer shell 91 should be located at the middle position inside the U-shaped frame 81. Since the spring telescopic rod 85 is installed inside the buffer plate 86 on one side, when the thermal insulation outer shell 91 contacts the buffer plate 86, the spring telescopic rod 85 will be compressed to provide an initial buffer force to absorb the low-frequency vibration generated during the high-speed dispersion process, thereby protecting the equipment from impact. Next, by tightening the locking rod 84 into the second fixed sleeve 93, the lateral displacement of the thermal insulation outer shell 91 is further restricted. The locking rod 84 passes through the first fixed sleeve 83 and inserts into the second fixed sleeve 93 to form a stable connection structure to ensure the stability of the thermal insulation outer shell 91 in the horizontal direction. To enhance the fixing effect of the thermal insulation outer shell 91, the first tightening belt 11 and the second tightening belt 12 are also used to bind its outer surface. The specific operation is to pass one end of the first tightening belt 11 and the second tightening belt 12 through the second vertical rod 109 and the third vertical rod 110 in sequence and fixedly connect them to the first vertical rod 107, so as to evenly distribute the pressure, make the circumferential force on the thermal insulation outer shell 91 more uniform, and prevent deformation or damage caused by local stress concentration. During the high-speed stirring process, if the thermal insulation outer shell 91 shakes and squeezes the buffer plate 86, the spring telescopic rod 85 will be further compressed and push the T-shaped sliding plate 103 to slide along the limit rod 102 towards the vertical plate 7. This action will drive the toothed plates 104 on both sides of the T-shaped sliding plate 103 to move synchronously, and then drive the gear 108 to rotate. Since the gear 108 is fixedly connected to the first vertical rod 107, the first vertical rod 107 will also rotate accordingly, pulling the first tightening belt 11 and the second tightening belt 12 to perform an automatic tightening operation. Through this design, even if the thermal insulation outer shell 91 shakes slightly during the stirring process, the system can quickly respond and automatically adjust the tightening force to ensure that it is always in a stable state. At the same time, the presence of the second vertical rod 109 and the third vertical rod 110 enables the pressure to be evenly distributed, avoiding the risk of local overload.

[0038] The usage method provided by the present invention is as follows: S1: Add the material to be processed into the aggregation cylinder 141 inside the sealing cover 131 through the conical feeding pipe 134. Start the hydraulic rod 5 to lower the sealing cover 131 and closely fit it with the top of the thermal insulation outer shell 91. Then, connect an external vacuum pump through the evacuation pipe 133 to evacuate the inside of the inner tank 92 to prevent the generation of bubbles during the stirring process; S2: Adjust the opening angle of the stirring frame 183 of the mixing mechanism 18 according to the material viscosity. For high-viscosity materials, control the electric telescopic rod 186 to extend and push the sliding plate 182 downward, and drive the stirring frame 183 to open to 60° through the adjusting rod 184. For low-viscosity materials, contract the electric telescopic rod 186 to close the stirring frame 183 to 30°. At the same time, the shear ball 1874 realizes self-adaptive expansion under the action of centrifugal force to enhance the shear effect; S3: Then, start the servo motor 16 to drive the main shaft rod 161 to rotate, and drive the stirring frame 183 and the expansion assembly 187 to rotate synchronously at high speed through the rotating rod 172 to complete the efficient mixing of the materials. At the same time, the scraping wall plate 174 rotates with the rotating rod 172 to automatically clean the residual materials on the inner wall of the inner tank 92; S4: After the mixing is completed, turn off the vacuum pump and restore the normal pressure environment. Rotate the three-piece discharge ball valve to an opening degree of 45° to smoothly discharge the slurry. Then, release the thermal insulation shell 91 through the limit buffer mechanism 8 and the tightening mechanism 10, and slide it out along the guide rail of the bracket 6 to complete the entire processing process.

[0039] When the present invention is in use, first, start the hydraulic rod 5 to lower the sealing cover 131 and closely fit it with the top of the heat preservation housing 91 to ensure the system tightness; then add the materials to be mixed into the aggregation cylinder 141 in the sealing cover 131 through the conical feeding pipe 134. Subsequently, connect an external vacuum pump through the evacuation pipe 133 to evacuate the inside of the inner tank 92 to prevent the generation of bubbles during stirring from affecting the quality of the slurry. Before starting the stirring, adjust the opening angle of the stirring frame 183 of the mixing mechanism 18 according to the viscosity parameter of the material. For example, for high-viscosity materials, extend the electric telescopic rod 186 to drive the slide plate 182 to move downward, and the adjusting rod 184 pushes the stirring frame 183 to open to 60°; for low-viscosity materials, close it to a 30° angle to adapt to different shear requirements. After confirming that the angle adjustment is completed, start the servo motor 16 to drive the main shaft rod 161 to rotate, and drive the stirring frame 183 and the expansion assembly 187 to rotate synchronously at high speed through the rotating rod 172. During the high-speed rotation process, the shear ball 1874 expands outward under the action of centrifugal force, dynamically enhancing the shear effect, effectively breaking up agglomerated particles, and improving the dispersion uniformity; at the same time, the scraping wall plate 174 rotates with the rotating rod 172 to automatically clean the residual materials on the inner wall of the inner tank 92, reducing manual intervention and improving the cleaning efficiency and mixing consistency. During the entire mixing process, the heating pipe in the heat preservation housing 91 continuously works to maintain the temperature of the inner tank 92 stable, avoiding changes in the slurry performance caused by low temperature or delay in the response of the hydraulic system; after the mixing is completed, turn off the vacuum pump and restore normal pressure, rotate the three-piece discharge ball valve to an opening of 45° to smoothly discharge the slurry, and due to the optimized valve structure, the residue can be significantly reduced to avoid cross-contamination. In addition, during the operation of the equipment, the limit buffer mechanism 8 and the tightening mechanism 10 cooperate with each other to absorb vibration through the spring telescopic rod 85, and automatically adjust the tightening force with the first tightening belt 11 and the second tightening belt 12 to ensure that the storage assembly 9 remains stable during high-speed stirring, preventing deviation or shaking from affecting the mixing quality.
