An Efficient Vacuum Drying Device for Nanomaterial Powder

Abstract

The invention discloses a high-efficiency vacuum drying device for nanomaterial powder, which comprises a kettle body and a cover body. The inner ring of the partition forms a cylindrical grinding chamber, the inner wall of the grinding chamber is sealed and slidably connected with a grinding plate, the inner lower wall of the kettle body is fixedly connected with a motor, and the upper end of the motor is fixedly connected with a slanting plate, The sloping plate is located below the partition, the output shaft of the motor runs through the sloping plate and is fixedly connected to the axis of the grinding plate, and a plurality of return springs are fixedly connected to the upper wall of the sloping plate. The advantage is that the electron emitter emits electrons and attaches to the material. When the material moves to the magnetic plate along the guide plate, the magnetic field at the magnetic plate makes the charged material deflect downward and fall back into the grinding chamber, and the drying The water vapor released will float up to the suction pipe and be sucked away by the vacuum machine to complete the drying.

Description

technical field [0001] The invention relates to the technical field of nanomaterial preparation, in particular to an efficient vacuum drying device for nanomaterial powder. Background technique [0002] The main factors affecting the drying effect of materials in the vacuum dryer are: vacuum degree, radiation plate temperature, radiation heat transfer efficiency, initial water content, initial temperature, etc.; the drying efficiency is mainly restricted by the radiation plate temperature and radiation heat transfer efficiency. Drying powder at an excessively high radiant plate temperature will easily lead to agglomeration and defects. Therefore, there is a critical point in the radiation heat transfer temperature. When the radiation temperature is constant, the mixing effect caused by the slippage of the material during rotation is weak, and the heat transfer efficiency is low. Low, prone to local overheating and wall sticking, the quality of the prepared powder is limited....
