[0014] A drying process of a drying device for silicon carbide micropowder, using the above-mentioned drying device for silicon carbide micropowder, comprises the following steps:

[0015] Step 1: Manually pull the sealing plate to move to the left, and the sealing plate moves to the left to release the seal on the feed frame. After the seal of the feed frame is released, put the material into the feed frame;

[0016] Step 2: At the same time, the servo motor drives the rotating rod to rotate, the rotating rod drives the hollow rod to rotate, the hollow rod drives the extrusion rod to rotate, the extrusion rod rotates to contact the arc surface block and extrude the arc surface block;

The extrusion rod moves in a direction away from the dehumidification device, driving the hollow rod to move. The hollow rod moves in a direction away from the dehumidification device, driving the breaking rod to move.

[0018] Step 4: After the extrusion rod continues to rotate and disengages from the cambered surface block, the hollow rod moves and resets toward the dehumidification device under the elastic force of the No. 3 spring. The hollow rod moves and resets toward the dehumidification device, driving the breaking rod to move and reset.

[0020] The present invention provides a drying device for silicon carbide micropowder, which has the following beneficial effects:

[0021] (1) The invention drives the breaking rod to move and reset by moving the hollow rod toward the direction close to the dehumidification equipment. The breaking rod moves back and forth longitudinally and rotates to break up the materials to be dried entering the drying box. By breaking up the materials, it is possible to prevent the materials from agglomerating or caking, thereby ensuring that the granular materials can be evenly heated by the drying equipment, avoiding local overheating or insufficient heating, thereby improving the uniformity of the material during drying. The vibration of the arc rod drives the rotating rod to vibrate, and the vibration of the rotating rod drives the hollow rod and the breaking rod to resonate together. The vibration of the breaking rod makes the materials dispersed more evenly, thereby helping to improve the breaking effect of the breaking rod.

[0022] (2) In the present invention, the material feeding inside the feed frame is controlled by the reciprocating rotation of the material feeding plate by rotating the material feeding plate upward to contact the fixed plate and restore the seal of the feed frame. The material feeding amount can be controlled to ensure that the material is evenly distributed in the drying box, thereby avoiding excessive or insufficient drying due to too fast or too slow feeding, thereby improving the drying efficiency. The sealing plate is moved to the right to reset and restore the seal on the top of the feed frame to prevent the dust generated by the feeding from leaking out. The sealing plate prevents the dust from leaking out, thereby avoiding unnecessary material waste and greatly reducing the pollution of the dust to the external environment.

[0023] (3) The invention drives the dividing plate to move and reset through the linkage hole by the L-shaped rod. The dividing plate moves back and forth to cooperate with the dividing holes to divide the falling materials to prevent material accumulation. The reciprocating motion of the dividing plate can effectively divert and guide the materials, so that the materials remain in a loose state, thereby helping to reduce the occurrence of material agglomeration and further improving the drying effect. By preventing the air inlet pipe from being blocked, the extraction efficiency of the dehumidification equipment through the air inlet pipe is improved, and the moisture inside the drying box is effectively removed in time, further accelerating the drying process of the materials, thereby improving the overall drying efficiency.

2. The method for using a drying device for silicon carbide micropowder according to claim 1, characterized in that: The following steps are involved: Step 1: Manually pull the sealing plate to move to the left, and the sealing plate moves to the left to release the seal on the feed frame. After the seal of the feed frame is released, put the material into the feed frame; Step 2: At the same time, the servo motor drives the rotating rod to rotate, the rotating rod drives the hollow rod to rotate, the hollow rod drives the extrusion rod to rotate, the extrusion rod rotates to contact the arc surface block and extrude the arc surface block; Step 3: The extrusion rod is subjected to the reaction force of the extrusion arc surface block and moves in a direction away from the dehumidification device. The extrusion rod moves in a direction away from the dehumidification device, driving the hollow rod to move. The hollow rod moves in a direction away from the dehumidification device, driving the breaking rod to move. Step 4: After the extrusion rod continues to rotate and disengages from the cambered surface block, the hollow rod moves and resets toward the dehumidification device under the elastic force of the No. 3 spring, and the hollow rod moves and resets toward the dehumidification device, driving the scattering rod to move and reset; the scattering rod reciprocates longitudinally and rotates to scatter the materials to be dried entering the drying box; Step 5: After the material enters the drying box, the drying equipment and the dehumidification equipment work synchronously to dry the material inside the drying box.
