Silicon nitride powder preparation device and preparation method thereof
The invention belongs to the technical field of silicon nitride powder preparation, and discloses a silicon nitride powder preparation device and a preparation method thereof.The silicon nitride powder preparation device comprises a kettle body, a power pipe is movably installed in the middle of an inner cavity of the kettle body, a connecting shaft is fixedly connected to the middle of the top end of the power pipe, and the power pipe is movably connected with the top end of the inner cavity of the kettle body through the connecting shaft; a power assembly is fixedly mounted in the bottom end of the kettle body. Nitrogen needed during preparation of silicon nitride powder is utilized, namely, along with increase of raw materials, the nitrogen can be selectively input into a fixed pipe, along with continuous increase of the raw materials, the nitrogen input into the fixed pipe is increased, and finally the height of a movable plate is driven to change, namely, the higher the height of the movable plate is, the higher the nitrogen is, the higher the nitrogen is. At the moment, the upward deflection range of the stirring shaft is increased, namely, the whole stirring shaft is upwards stirred, so that the contact range between the stirring shaft and the added raw materials can be enlarged, the added raw materials can be fully mixed and stirred, and the reaction efficiency is improved.
本发明属于氮化硅粉制备技术领域，且公开了一种氮化硅粉制备装置及其制备方法，包括釜体，所述釜体内腔的中部活动安装有动力管，所述动力管顶端的中部固定连接有连接轴，所述动力管通过连接轴与釜体内腔的顶端之间活动连接，所述釜体底端的中固定安装有动力组件。本发明通过对进行氮化硅粉进行制备时所需的氮气进行利用，即随着原料的增加，可将氮气选择性的输入至固定管的内部，并随着原料的持续增加，输入至固定管内部的氮气随之增加，最终带动活动板高度发生变化，即活动板高度越高，此时搅拌轴向上偏转的范围随之增加，即整体朝上进行搅拌，可提高与增加的原料之间的接触范围，使得增加的原料均能得到充分混合搅拌，提高反应效率。
