Device for producing fullerene efficiently with arc process

Abstract

The invention discloses a device for producing fullerene efficiently with an arc process. The device comprises a vacuum furnace, wherein more than one independent electric arc sources is mounted in the vacuum furnace; each electric arc source comprises an anode, a cathode and a cathode trigger, and the anode, the cathode and the cathode trigger form a zigzag diversion loop; and an anode and a cathode trigger of each electric arc source can produce electric arcs simultaneously, so that a mixture containing the fullerene is produced. According to the device, the problem that during production of the fullerene with an existing arc process, scientific researches in laboratories are converted to industrial batch production is solved, and the fullerene and metal fullerene can be produced automatically, continuously and efficiently.

Description

technical field [0001] The invention discloses a high-efficiency fullerene production device by an arc method, which belongs to the technical field of fullerene production device manufacturing according to the International Patent Classification (IPC). Background technique [0002] Fullerenes are carbon, graphite and other allotropes. The most common ones are hollow fullerenes such as C60 and C70 and metal fullerenes containing other elements. At present, the preparation of fullerenes is still in the stage of gram-level production in the laboratory. With the promotion of the application of fullerene and metal fullerene, the market demand for fullerene and metal fullerene has increased greatly, and the original laboratory scientific research equipment has been unable to meet the requirements.

Problems solved by technology

[0002] Fullerenes are carbon, graphite and other allotropes. The most common ones are hollow fullerenes such as C60 and C70 and metal fullerenes containing other elements. At present, the preparation of fullerenes is still in the stage of gram-level production in the laboratory. With the promotion of the application of fullerene and metal fullerene, the market demand for fullerene and metal fullerene has increased greatly, and the original laboratory scientific research equipment can no longer meet the requirements

[0003] The preparation of fullerene by electric arc method is a commonly used method at present. It is formed by evaporating the graphite electrode through the electric arc discharge of the cathode and anode electrodes in the arc synthesis furnace, and then cooling it. It is a linearly arranged decentralized layout. Therefore, a synthesis furnace is equipped with an arc source composed of anode and cathode electrodes, which has low efficiency and low output, which cannot meet the requirements of industrial production.

[0004] Chinese document CN201010591761.0 discloses a rotary electric arc synthesis furnace for preparing fullerene nanomaterials, in which the anode electrode and cathode electrode of the arc source are arranged opposite to each other and the connected cathode rod and anode push rod extend in opposite directions and pass through the furnace body Left and right; Chinese document CN 200510124525.7 discloses a method for producing fullerenes in a temperature-controlled electric arc furnace, in which the electric arc furnace adopts an anode turntable with 1-6 consumed anode rods, but the negative and positive electrodes of the arc source The layout is the same as the previous literature, and its capacity and efficiency are lower
