Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of particle shaping, especially relates to a silicon carbide particle shaping machine. BACKGROUND

[0002] As an important industrial material, silicon carbide has a wide range of applications in many fields such as abrasive tools, electronic ceramics, and refractory materials. The shape and size distribution of its particles play a key role in product performance, so silicon carbide particle shaping machines have become key equipment in related industries. With the increasing demand for quality of silicon carbide products in modern industry, more stringent standards have been set for the performance of particle shaping machines, which has prompted researchers and engineers to continuously explore and improve related technologies and equipment to meet the growing market demand.

[0003] In traditional silicon carbide particle shaping technology, the common mechanical structure mainly adopts a relatively simple fixed speed grinding method, which generally uses a single drive motor to drive the grinding wheel fixed on the same shaft to rotate. The surface of the grinding wheel is relatively smooth and flat, and only relies on single rotation friction to shape the silicon carbide particles. At the same time, during the shaping process, the transmission of the particles mainly relies on gravity to naturally fall to the next link, lacking effective active transmission and uniform distribution mechanism, resulting in uneven distribution of particles in each processing area, and unable to fully utilize the overall efficiency of the equipment. Moreover, the chamber structure of the entire device is relatively simple, and is not optimized for different stages of particle state, and cannot achieve efficient staged circulation processing.

[0034] Specifically, in use of the silicon carbide particle shaper, the worker first pours the silicon carbide particles into the interior of the grinding box 1 through the feeding slot 2.

When the feeding amount increases or the particle size is uneven, the controller receives signals from the feeding amount monitoring sensor and the particle size analyzer, and correspondingly increases the rotational speed difference of the driving motors 6 according to the preset program. Specifically, the controller increases the rotational speed of part of the driving motors 6 to be higher than that of the other motors, so that the silicon carbide particles are subjected to stronger and uneven shear force, and the change of the shear force enables the particles to collide and rub with each other more fully in the grinding process, thereby more efficiently shaping the silicon carbide particles. After the silicon carbide particles are ground to a certain extent, the electric pusher 11 at the bottom of the partition plate 4 starts to work, the driving device in the electric pusher 11 generates a linear pushing force to drive the push rod 12 to move in the vertically downward direction, the movement of the push rod 12 drives the connecting plate 13 welded on the side wall of the push rod 12 to move synchronously downward, the movement of the connecting plate 13 further drives the separation inner plate 15 to slide along the horizontally outward direction in the inner wall of the square hole 16 of the separation outer plate 14, at this time, the square hole 16 on the surface of the separation inner plate 15 is accurately aligned with the square hole 16 on the surface of the separation outer plate 14, so that the silicon carbide particles after preliminary grinding in the upper chamber will fall into the middle chamber through the aligned square holes 16 under the action of gravity. After entering the middle chamber, the fan 9 located on the side of the chamber starts to work, the impeller of the fan 9 rotates at high speed to generate high-speed airflow, the airflow enters the middle chamber through the sealingly connected air outlet pipeline 10, and is blown out towards the area where the grinding balls 17 and the silicon carbide particles are located, so that the silicon carbide particles are driven by the high-speed airflow to collide and rub with the grinding balls 17. The grinding balls 17 will make irregular rolling and jumping movements on the upper surface of the separation outer plate 18 under the impact of the airflow, frequently contact the silicon carbide particles, further refine and regularize the particle shape, so as to achieve the effect of efficient and accurate classification and cyclic shaping of the silicon carbide particles. Then, the electric pusher 11 at the bottom of the middle chamber is started again to drive the separation inner plate 19 to move in the vertical direction inside the separation outer plate 18, so that the circular hole 20 on the separation inner plate 19 is aligned with the circular hole 20 on the separation outer plate 18, so that the silicon carbide particles after being shaped by the airflow impact and the grinding balls 17 fall into the lower chamber at the bottom of the grinding box 1 through the circular hole 20, completing the classification and cyclic shaping process of the particles.

[0035] Reference Figure 2The bottom of the grinding box 1 is provided with a discharge pipeline 5 for conveying the shaped silicon carbide particles to the next processing link, which is made of stainless steel with a smooth inner wall, which can effectively reduce the resistance of the particles in the conveying process, ensure that the particles can smoothly and quickly pass through, the outer wall of the discharge pipeline 5 is fixedly connected to the bottom of the grinding box 1 by welding process, which ensures the sealing and stability of the connection between the two, prevents the leakage of particles during the conveying process, the inside of the discharge pipeline 5 is communicated with the inside of the grinding box 1, and a driving motor two 23 is arranged on one side of the discharge pipeline 5, and the outer wall of the driving motor two 23 is fixedly connected to the side wall of the discharge pipeline 5, and a transmission shaft 21 is fixedly connected to the output end of the driving motor two 23 through a shaft coupling, and the outer wall of the transmission shaft 21 penetrates through the side wall of the discharge pipeline 5, and the transmission shaft 21 is made of high-strength alloy steel, which has enough rigidity and torque transmission capacity, and can withstand the resistance and torque generated by the spiral blade 22 during conveying particles, and the outer wall thereof penetrates through the side wall of the discharge pipeline 5 and is connected with the side wall of the discharge pipeline 5 through a sealing bearing. This connection mode not only ensures that the transmission shaft 21 can rotate flexibly, but also prevents particles from entering the motor side from the connection, affecting the normal operation of the motor. The outer wall of the transmission shaft 21 is fixedly connected with the spiral blade 22, and the spiral blade 22 is made of wear-resistant alloy material, and its surface is treated with special texture to increase the friction between the particles. The spiral blade 22 is slidably connected to the inner wall of the discharge pipeline 5;

[0036] Specifically, when the silicon carbide particles complete shaping in the grinding box 1 and enter the lower chamber, the particles will naturally fall into the discharge pipeline 5 under the action of gravity because the lower chamber is communicated with the discharge pipeline 5. Then, the driving motor two 23 on the side wall of the discharge pipeline 5 starts to operate, the rotor in the driving motor two 23 rotates at high speed in the clockwise direction, and the power is transmitted to the transmission shaft 21 through the shaft coupling, so as to drive the transmission shaft 21 to stably rotate in the clockwise direction in the sealing bearing on the side wall of the discharge pipeline 5. The rotation of the transmission shaft 21 further drives the spiral blade 22 fixed to the outer wall of the transmission shaft 21 to rotate in the clockwise direction. During the rotation of the spiral blade 22, the blades of the spiral blade 22 will continuously push the silicon carbide particles on the inner wall of the discharge pipeline 5 forward along the axial direction of the discharge pipeline 5. Because the pitch and blade shape of the spiral blade 22 are carefully designed, the particles can maintain uniform distribution and stable flow rate during the pushing process, avoiding the accumulation of particles or uneven flow rate, thereby uniformly conveying the silicon carbide particles out of the inner wall of the discharge pipeline 5, so that the silicon carbide particles smoothly enter the next processing link. In this way, the effect of uniformly conveying the silicon carbide particles is achieved, which provides stable and reliable material supply guarantee for the subsequent production process, and improves the continuity and stability of the entire production process.

[0037] Working principle: in use, the worker first pours the silicon carbide particles into the inside of the grinding box 1 through the inlet chute 2, then the upper chamber of the inner wall of the grinding box 1 starts to rotate, driving the grinding roller 7 to start synchronous rotation, the rotation of the grinding roller 7 drives the multiple grinding baffles 8 on its surface to rotate, under the rotation of the multiple grinding rollers 7, the silicon carbide particles are ground, when the feed amount increases or the particle size is uneven, the controller will correspondingly increase the rotational speed of the driving motor 6, so that the silicon carbide particles are subjected to more intense and uneven shear force, thereby more efficiently shaping the silicon carbide particles, after the silicon carbide particles are ground, the electric pusher 11 at the bottom of the baffle 4 drives the push rod 12 to displace, the push rod 12 drives the connecting plate 13 to displace, the connecting plate 13 drives the separation inner plate 15 to slide outward on the inner wall of the square hole 16, at this time the square hole 16 on the panel of the separation inner plate 15 will align the square hole 16 on the separation outer plate 14, so that the ground silicon carbide particles will fall into the middle chamber, after entering the middle chamber, at this time the fan 9 located on the side of the chamber starts to blow the silicon carbide particles and the grinding balls 17 in the chamber through the air outlet duct 10, the silicon carbide particles are driven by the high-speed airflow to collide and rub with the grinding balls 17, further refining and shaping the shape, so as to achieve the effect of efficient and accurate classification and cyclic shaping of the silicon carbide particles, then the electric pusher 11 at the bottom thereof drives the separation inner plate 19 to displace inside the separation outer plate 18, so that the silicon carbide particles fall into the lower chamber at the bottom of the grinding box 1 along the circular hole 20, the lower chamber is communicated with the discharge duct 5, so the silicon carbide particles will fall into the discharge duct 5, then the driving motor 23 on the side wall of the discharge duct 5 drives the transmission shaft 21 to rotate, the transmission shaft 21 drives the spiral blade 22 to rotate, uniformly conveying the silicon carbide particles out of the inner wall of the discharge duct 5 to the next processing link, so as to achieve the effect of uniformly conveying the silicon carbide particles.
