Efficient carbon fiber pre-oxidation furnace

Abstract

The invention relates to the technical field of carbon fiber pre-oxidation, in particular to an efficient carbon fiber pre-oxidation furnace which comprises a furnace body shell, a conveying unit and a pre-oxidation unit. The conveying unit is arranged in the furnace body shell; and the pre-oxidation unit is installed on the inner wall of the furnace body shell. The efficient carbon fiber pre-oxidation furnace provided by the invention can solve the following problems that the rigidity of the outer side of a conveying roller arranged in a traditional pre-oxidation furnace is large, so that raw filaments are prone to being extruded and broken, and the raw filaments are prone to being wound; the existing pre-oxidation furnace cannot effectively change the heating area of the raw filaments , so that the pre-oxidation effect on the raw filaments is influenced; by means of annular rubber pads, the situation that the rigidity of the conveying roller is too large, and consequently the raw filaments are extruded and broken can be avoided, and winding of the raw filaments can be prevented through multiple guide cylinders; and when the efficient carbon fiber pre-oxidation furnace provided by the invention is used for performing pre-oxidation treatment on the raw filaments, the heating area of the raw filaments can be adjusted, so that efficient pre-oxidation treatment on the raw filaments by the pre-oxidation unit can be realized.

Description

technical field [0001] The invention relates to the technical field of carbon fiber pre-oxidation, in particular to a carbon fiber high-efficiency pre-oxidation furnace. Background technique [0002] Pre-oxidation refers to the pre-oxidation process that the raw silk must go through before carbonization. The purpose of pre-oxidation is to transform the linear macromolecular chain of the raw silk into a heat-resistant ladder structure after pre-oxidation treatment, which is non-melting and non-combustible, and can withstand High-temperature carbonization keeps the fiber shape, so as to obtain high-quality carbon fiber. [0003] However, the current carbon fiber pre-oxidation has the following problems: 1. Most of the traditional pre-oxidation furnaces transport multiple raw filaments synchronously through the transmission roller. Due to the high rigidity of the outer side of the ordinary transmission roller, it is easy to cause damage to the raw filaments. Extrusion breaks, ...

Problems solved by technology

[0003] However, the current carbon fiber pre-oxidation has the following problems: 1. Most of the traditional pre-oxidation furnaces transport multiple raw filaments synchronously through the transmission roller. Due to the high rigidity of the outer side of the ordinary transmission roller, it is easy to cause damage to the raw filaments. Extrusion breaks, and the entanglement between the original filaments is easy to occur

[0004] 2. The existing pre-oxidation furnace cannot effectively adjust the gap between the original wires when performing pre-oxidation treatment on the original wires, so the heating area of ​​the original wires cannot be changed, thus affecting the pre-oxidation effect on the original wires
