[0061] The present invention is further explained below in conjunction with specific implementation modes.

[0062] See also Figure 1-Figure 11 , an embodiment of the present invention provides a particle size control device for silicon micropowder production, the particle size control device for silicon micropowder production comprising:

[0063] A shell 1 and an airflow classification device, a feed pipe 2 on the shell 1, and a discharge pipe 5 is provided at the bottom of the shell 1; the discharge pipe 5 can be used to introduce the fully crushed silicon micropowder into the airflow classification device, wherein the airflow classification device is an existing public technology, and the airflow classification device can select gravity, centrifugal or inertial airflow classification equipment according to actual use requirements. Further, the working principle is:

[0064] Gravity airflow classifier: When particles are in the airflow, they are affected by the combined effects of gravity and airflow drag. Particles with larger particle size and heavier mass are relatively more affected by gravity and fall faster in the airflow, and will gather near the bottom of the classifier or in the gravity sedimentation area; while particles with smaller particle size and lighter mass are more affected by the airflow drag and can stay in the airflow for a longer time, moving upward or in other directions with the airflow, thereby achieving the initial separation of large particles and small particles. Centrifugal airflow classifier: In the centrifugal airflow classifier, the airflow carries the particles into the classifying rotor area, and the classification The high-speed rotation of the rotor will generate a strong centrifugal force. Under the action of the centrifugal force, particles with larger sizes are thrown to the outside of the grading rotor, while particles with smaller sizes will move to the center area of ​​the grading rotor under the action of the airflow due to the smaller centrifugal force. By adjusting the speed of the grading rotor, the size of the centrifugal force can be changed, thereby achieving the separation of particles of different sizes. Inertial airflow grading equipment: Classification is carried out using the difference in inertia of particles when they move in the airflow. When the airflow encounters an obstacle or the channel suddenly changes direction in the grading equipment, the particles will continue to move in the original direction due to inertia. Particles with larger sizes have greater inertia and are more difficult to change direction with the airflow. They will collide with obstacles or deviate from the airflow direction and be separated; while particles with smaller sizes have less inertia and can better change direction with the airflow, thereby achieving the separation of particles of different sizes.

[0065] A crushing mechanism located in the housing 1, the crushing mechanism includes a fixed crushing block 7 and a movable crushing member used in conjunction with the fixed crushing block 7, and the housing 1 is also provided with a driving unit for driving the movable crushing member to rotate, the fixed crushing block 7 is also provided with a reverse crushing component for enhancing the crushing effect, and the movable crushing member is provided with a linkage component for working with the reverse crushing component;

[0066] And a control component for adjusting the working position of the movable rolling member, wherein the control component is arranged in the housing 1.

The driving unit can realize the rolling and crushing processing of the silicon micropowder by driving the movable rolling member to rotate. The linkage component is used to drive the reverse rolling component to rotate, so that the silicon micropowder can be kneaded in the direction opposite to the rotation direction of the movable rolling member, thereby further improving the crushing effect, so that the large particles in the silicon micropowder are fully crushed. The fully crushed silicon micropowder will fall to the bottom of the shell 1 and be discharged through the discharge pipe 5. The silicon micropowder can be screened by the air flow classification equipment, and the silicon micropowder of different particle sizes can be separated to achieve the particle size control effect, which is convenient for meeting different usage requirements. Compared with the prior art, the present invention avoids the problem that the structure used for crushing in the existing particle size control equipment for silicon micropowder production is relatively simple, and it is difficult to fully crush the larger particles in the silicon micropowder, resulting in poor particle size control effect and difficulty in making the silicon micropowder meet production requirements through the coordinated arrangement of the crushing mechanism and the control component.

[0095] The air outlet holes 31 are provided in a plurality of groups on the air guide ring 21, and the air outlet holes 31 are connected to the cavity in the air guide ring 21;

[0102] In this embodiment, when in use, the air intake pipe 4 is connected to the external air source. When the working positions of the movable rolling block 2 12 and the movable rolling block 1 6 need to be adjusted, the air intake pipe 4 is used to transport the gas to the air guide ring 21. The gas can enter the compression chamber 1 32 and the connecting ring 44 through the driving pin 30. The gas entering the compression chamber 1 32 can cause the piston 1 8 and the compression chamber 1 32 to move relative to each other, so that the movable rolling block 1 6 can be pressed onto the fixed rolling block 7. At this time, the movable rolling block 1 6 and the movable rolling block 2 12 are in a state of being pressed relative to each other. The connecting belt 13 is used to prevent the silicon powder from entering the gap between the movable rolling block 2 12 and the movable rolling block 1 6. At the same time, the gas will enter the compression chamber 2 33 through the conduit 29 to push the linkage pin 28 to move upward. When the linkage pin 28 rotates to a position corresponding to the blocking pin 34, it will push the blocking pin 34 to move upward.

In the process of the rotation of the annular driving block 17, the magnet 2 19 intermittently passes under the magnet 1 14. Each time it passes, the magnet 1 14 will push the magnet 2 19 downward, so that the pressing rod 18 drives the piston 2 36 to press the gas in the compression cylinder 24 into the To the shunt pipe 23, and the gas is transported to the compression chamber three 38 through the shunt pipe 23 to push the piston three 39 downward, so that the piston three 39 drives the disturbance rod 35 to press on the movable rolling block two 12, so as to achieve the disturbance treatment of the silicon micropowder, and avoid the problem that the silicon micropowder is flattened between the movable rolling block two 12 and the fixed rolling block 7 and the fluidity is affected, thereby affecting the crushing effect. When the magnet two 19 passes under the magnet one 14, the spring two 40 and the spring one 37 can respectively push the piston three 39 and the piston two 36 to reset;

[0103] By utilizing the pressing action of the driving rod 9 on the driven tube 10, the annular driving block 17 is pressed on the air guide ring 21. When the containing groove 22 is connected to the air outlet 31, the gas ejected from the air outlet 31 will be received by the containing cavity in the movable rolling block 12, and part of the gas can be ejected through the spray hole on the surface of the movable rolling block 12, further improving the turbulence effect. When the containing groove 22 and the air outlet 31 are staggered, the gas ejected from the air outlet 31 will push the movable rolling block 12 to move upward, so that the movable rolling block 12 can intermittently move up and down during the rotation process, thereby realizing the impact on the silicon micropowder between the fixed rolling block 7 and the movable rolling block 12, and further improving the crushing effect.

[0104] The air inlet pipe 4 can intermittently input gas into the air guide ring 21 to continuously adjust the working states of the movable rolling block 2 12, the movable rolling block 1 6, the linkage assembly and the reverse rolling assembly, thereby further improving the processing quality.
