Silica micropowder is widely used in many fields due to its excellent performance. It is an important inorganic non-metallic functional filler and plays an important role in many fields.

[0003] Traditional silicon micropowder processing equipment not only has low crushing efficiency, but also the screen plate is very easy to be blocked, affecting the processing effect. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the shortcomings of the prior art, the present invention provides a silicon micropowder airflow crushing device, which solves the problem that excess lubricating oil cannot be well recovered, which not only easily pollutes the chain, but also causes waste of resources.

[0006] Preferably, the driving teeth and the transmission teeth are both retractable and adjustable teeth.

[0007] Preferably, the multiple crushing rods fixedly connected to the outer side wall of the same transmission rod can be distributed in a ring array or in a staggered manner.

[0008] Preferably, a sieve plate is provided inside the processing box, and one end of the transmission rod at the rearmost position away from the transmission rod at its nearest position passes through the sieve plate, a mounting opening is opened at the center of the sieve plate, a transmission flexible shaft is fixedly connected to the inner side wall of the mounting opening, and a driving shaft is fixedly connected to the outer surface of the transmission rod at the rearmost position away from the transmission rod at its nearest position, and the driving shaft is located inside the mounting opening, and the gap between the mounting opening and the transmission rod is closed by a cover plate.

[0009] Working principle: When in use, place the silicon micropowder to be crushed under the servo motor, open the feed port below it, start the servo motor, and the driving end of the servo motor drives the center rod to rotate at high speed with the negative pressure fan. The negative pressure generated will drive the silicon micropowder to move toward the sieve plate. When the silicon micropowder moves toward the sieve plate, the transmission cylinder will transfer power to the transmission rod through the driving teeth on the inner wall and the transmission teeth on the outer surface of the transmission rod. The adjacent transmission rods also transmit power in this way, thereby driving the crushing rod on the outer surface of the center rod to rotate. As the silicon micropowder moves under the action of the airflow, The silicon micropowder is broken up. Since the transmission teeth and the driving teeth are both retractable and adjustable teeth, the transmission ratio can be changed, and then the rotation speed of the crushing rod on the outer surface of each transmission rod can be adjusted to form a differential rotation mode. In conjunction with the movement of the silicon micropowder airflow, the silicon micropowder material is gradually broken up to achieve a full crushing effect. The broken materials will pass through the sieve plate and be collected on the other side of the sieve plate. During the processing, the sieve plate will be intermittently driven by the drive shaft through the transmission soft shaft, and will rotate and oscillate under the action of inertia to avoid blockage caused by excessive adsorption of materials and ensure the processing effect.

[0010] (III) Beneficial effects The present invention provides a silicon micropowder airflow pulverizing device, which has the following beneficial effects: 1. The silicon micropowder airflow pulverizing device, since the transmission teeth and the driving teeth are both retractable and adjustable teeth, the transmission ratio can be changed, and then the rotation speed of the pulverizing rod on the outer surface of each transmission rod can be adjusted to form a differential rotation mode. With the movement of the silicon micropowder airflow, the silicon micropowder material is gradually broken up to achieve a full pulverizing effect.

[0011] 2. In the process of processing, the sieve plate of the silicon micropowder air flow crushing device will be intermittently driven by the driving shaft through the transmission flexible shaft, and will rotate and oscillate under the action of inertia to avoid blockage caused by excessive adsorption of materials and ensure the processing effect.
