A high temperature rotary tube furnace

Abstract

The invention belongs to the field of tube furnaces and particularly relates to a high-temperature rotating tube furnace. The high-temperature rotating tube furnace comprises a high-temperature furnace body; a rotating hole is formed in the inner wall of one side of the high-temperature furnace body; a rotating shaft is rotationally installed in the rotating hole; the two ends of the rotating shaft extend to the outside of the rotating hole; one end of the rotating shaft extends into the high-temperature furnace body to be fixedly provided with a furnace tube; an annular groove is formed in the rotating shaft; a sliding block is slideably installed in the annular groove; one side of the sliding block extends to the outside of the annular groove; a fixed plate is fixedly installed on the inner wall of the top side of the high-temperature furnace body; two vertical columns are fixedly installed on the inner wall of one side of the fixed plate; and a sliding hole is formed in one side of the vertical column which is close to the rotating shaft. An L-shaped sliding rod is driven to slide back and forth while a motor is in rotation so that two impact rods can be driven to impact on the furnace tube back and forth, raw materials in the furnace tube are vibrated, raw material agglomeration is prevented, the raw materials in the tube can conveniently rotate along with the furnace tube, the raw materials are dried uniformly, and the using demands of people are met.

Description

technical field [0001] The invention belongs to the field of tube furnaces and relates to a high-temperature rotary tube furnace. Background technique [0002] Graphene is made of sp 2 The single-layer planar graphite, which is bonded by hybridized carbon atoms and has a hexagonal lattice honeycomb two-dimensional structure, has a thickness of only 0.34nm and theoretically has excellent mechanical, thermal, optical and electrical properties.
