The invention relates to microwave graphite puffing equipment. The microwave graphite puffing equipment comprises a microwave heating cavity, a positive-pressure material scattering device, a microwave generator and the like, a positive-pressure material scattering device is arranged on the bottom wall of the microwave heating cavity and used for blowing away graphite materials entering the microwave heating cavity from the upper side of the microwave heating cavity in the vertical direction into the peripheral side space of the microwave heating cavity, and the positive-pressure material scattering device blows away the graphite materials into the peripheral side space of the microwave heating cavity, so that the graphite materials are in a scattered state as a whole. The microwave generator works to expand the graphite material in a dispersed state, the expansion uniformity of the graphite material in the dispersed state is better than that of the graphite material in a cumulative spreading state, the graphite material in the microwave heating cavity is in a dispersed state as a whole through the work of the positive pressure disperser, and the graphite material is effectively and uniformly heated, the puffing uniformity is better, the overall energy consumption of the equipment is low, and the environmental protection property and the economical efficiency are effectively improved.
Description
technical field [0001] The invention relates to the technical field of graphite expansion equipment, in particular to a microwave graphite expansion equipment. Background technique [0002] Expanded graphite is an important industrial raw material for the production of flexible graphite sheets, which are widely used as gaskets, sealing thermal insulators, etc. Existing methods for preparing expanded graphite include traditional high-temperature heating method and microwave method, etc. The preparation of expanded graphite by microwave method has the advantages of simplicity and high efficiency, and has been widely concerned and researched in the field; microwave method and traditional high-temperature expansion method are essentially the same, both are By heating, the compound inserted between the graphite layers is rapidly decomposed or vaporized at high temperature, and a large amount of gas is generated, so that the graphite is peeled off along the axis to form expanded g...
