Carbon fiber continuous production activating furnace

Abstract

The invention discloses a carbon fiber continuous production activating furnace which comprises an outer sealing framework, a gas sealing furnace body, a sealing drive assembly, a heating assembly and a humidifying assembly .The gas sealing furnace body is arranged in the outer sealing framework .The sealing drive assembly comprises a gas sealing pipe with openings in the two ends and a plurality of drive parts .The gas sealing pipe is located in a furnace cavity of the gas sealing furnace body .The drive parts are arranged at intervals and rotationally arranged in the gas sealing pipe .The two ends of each drive part extend out of the outer sealing framework .The heating assembly is arranged in the gas sealing pipe and connected with the gas sealing furnace body .The humidifying assembly comprises a humidifying pipe and a humidifier which are connected in a matched mode .The humidifying pipe is arranged in the furnace cavity .The humidifier is arranged outside the outer sealing framework .When the activating furnace is utilized for producing carbon fiber, the gas sealing pipe in the sealing drive assembly enables the carbon fiber to be in the relatively closed production environment, the carbon fiber is prevented from making contact with impurity gas, and the yield and quality of the carbon fiber are ensured.

Description

Technical field [0001] The invention belongs to the field of carbon fiber production equipment, and specifically relates to an activation furnace for continuous carbon fiber production. Background technique [0002] Carbon fiber is a new high-strength fiber material with high carbon content. It has the characteristics of low density, high strength, corrosion resistance, and high modulus. It is widely used in national defense, military, and civilian fields. At present, domestic carbon fiber is mainly purchased from overseas, and a small amount of carbon fiber is passed through batch furnaces in China. However, the existing batch furnace has the problem that the carbon fiber is easily in contact with the impurity gas, which results in the low output of the carbon fiber, poor product quality and instability. Summary of the invention [0003] The purpose of the present invention is to provide an activation furnace for continuous carbon fiber production, which can improve air tightnes...
