Problems solved by technology

[0003] The existing graphite carbonization furnaces use pure carbon tubes, which have the disadvantage of being easily broken. Therefore, great care must be taken during installation and transportation, and the service life is short in normal use.
[0004] In addition, the existing heating tube itself is a heat-generating component. After the graphite is placed in the heating tube, it is in direct contact with the carbon tube, and the graphite powder in the carbon tube cannot be stirred. Therefore, the graphite powder in the center is less heated, while the surrounding Graphite powder is heated more, resulting in uneven heating of graphite powder at different positions, resulting in uneven quality of graphite purification, and the quality of output graphite powder cannot be guaranteed
[0005] The existing purification method intelligently realizes the automation of material pushing, but cannot realize the automation of the whole system, and there are still many deficiencies in the existing system

Abstract

The invention discloses a full-process automatic graphite purification method. The method comprises the following steps: step 1, blanking and pushing; a carbon powder raw material is pushed into a double-layer heating pipe of a horizontal graphite carbonization furnace along a horizontal feeding pipe by adopting a discharging mechanism and a spiral pushing mechanism; step 2, high-temperature carbonization; the carbon powder is heated in a double-layer heating pipe of the horizontal graphite carbonization furnace; step 3, discharging; and the heated carbon powder passes through a discharge pipeof the horizontal graphite carbonization furnace and is conveyed into a container through a discharge mechanism to be packaged. According to the full-process automatic graphite purification method, the whole-process automatic control of blanking, feeding, discharging and temperature is adopted, the temperature in the furnace body can be kept constant, and the automation degree is high so that thegraphite carbonization quality is guaranteed.

Description

technical field [0001] The invention relates to a full-flow automatic graphite purification method. Background technique [0002] The function of the graphite carbonization furnace is to push the carbon powder into the furnace body, and further eliminate the impurities in the carbon powder (or turn it into flue gas, or directly carbonize) through the high temperature in the furnace body, so that the purity of the carbon powder can be further improved to meet the Industrial requirements, such as the use of purified carbon powder as high-performance electrodes. [0003] Existing graphite carbonization furnaces use pure carbon tubes, which have the disadvantage of being easily broken. Therefore, great care must be taken during installation and transportation, and the service life is relatively short during normal use. [0004] In addition, the existing heating tube itself is a heat-generating component. After the graphite is placed in the heating tube, it is in direct contact ...
