Embodiment Construction

[0008] The present invention will be described in further detail below in conjunction with the accompanying drawings of the embodiments, and is not a limitation of the present invention:

[0009] As shown in the drawings: the furnace body of this embodiment adopts a three-stage structure, and a feeding chamber (2) is added at the front end of the reaction chamber (8), and a guide rail is installed at the bottom of the feeding chamber (2), and a The material box (3) of the reactant, the front end of the feeding chamber (2) is equipped with a feeding hydraulic cylinder (1), and the output shaft of the hydraulic cylinder matches the material box, and the reaction cylinder (1) will be equipped with a reaction when the feeding hydraulic cylinder (1) moves. The material box (3) of the material is smoothly pushed into the reaction chamber (8) from the feed chamber (2) through the water-cooled transition zone (5) along the guide rail. A discharge chamber (14) is added behind the react...

Abstract

The invention relates to a nanometer material composite technique, belonging to a intelligent periodic controllable furnace for using phase method to continuously prepare the nanometer material. The inventive furnace is formed by a feeding room, a reaction room, and a discharging room. Wherein, two water-cooling transition areas are arranged between the reaction room and the feeding room, the reaction room and the discharging room. In production, putting the raw material in the material disc to be fed into feeding room; using hydraulic cylinder to push the material disc into reaction room; using another hydraulic cylinder to draw the reacted product from reaction room into discharging room to be cooled; and the feeding and discharging of material can be processed synchronously; the temperature of reaction room only need one increase, and the production can be continuously processed by keeping the working temperature. Compared to single-room furnace, it can improve the producing efficiency and the service life of reaction furnace and save the energy.

Description

Technical field [0001] The invention relates to the technical field of nanomaterial synthesis, in particular to an intelligent periodic controllable atmosphere furnace for continuously preparing nanomaterials by gas phase method. Background technique [0002] Due to the unique properties of nanomaterials and their important value in many aspects such as electronics, optics, military industry, chemical industry, ceramics, biology and medicine, they have aroused great interest of scientists from all over the world. There are various methods for the preparation of nanomaterials. Among the various preparation methods of nanomaterials, especially the gas phase method for preparing one-dimensional nanomaterials is a commonly used method at present. Due to the increased space for material nucleation and growth in the gas phase, the prepared nanomaterials have uniform morphology, small size, narrow size range distribution, and good monodispersity. Gas-phase preparation is mostly c...
