Embodiment 1

[0022] Specific embodiment 1 of the continuous pre-oxidation treatment device provided by the present invention, such as Figure 1 to Figure 4 As shown, the continuous pre-oxidation treatment device includes a pre-oxidation furnace. The pre-oxidation furnace includes a furnace body 9. The furnace body 9 is provided with a loading device 18 that provides the temperature required for pre-oxidation. The furnace body 9 is arranged for carbon fiber filaments The oxidation conveying unit transported from the furnace body inlet to the furnace body outlet includes two oxidation conveying chains 13 extending in parallel. The two oxidation conveying chains 13 are wound on the first gear 8 and the second gear 10, and are composed of two gears. In cooperation with driving the two oxidation conveying chains 13 to move to convey the carbon fiber filaments, the two oxidation conveying chains 13 are arranged at intervals in the horizontal direction to form a drop gap for the carbon fiber filame...

Embodiment 2

[0031] The main difference from embodiment 1 lies in: Figure 5 As shown, the structure of the front paving unit and the rear paving unit are the same. As an example, the previous paving unit includes an automated manipulator 22. The manipulator 23 of the automated manipulator grabs the corresponding upper support rod from the storage tank 24 and It can be placed on the supply conveyor chain. Correspondingly, the manipulator in the post-laying unit grabs the drop bar from the corresponding storage tank and places it on the carbon fiber.

[0032] The intermediate laying unit in this embodiment uses a cylinder pressure feeding device 28, a compression wheel structure 26, and a reversing wheel 29. The cylinder pressure feeding device 28 is located on the upper part of the supply conveyor chain and relies on the cylinder pressure feeding device 28 and the compression wheel structure 6. The carbon fiber filaments 27 are vertically conveyed downward in cooperation with each other, and t...

Abstract

The invention relates to a continuous pre-oxidation treatment device and a pre-oxidation furnace, wherein the pre-oxidation treatment device comprises the pre-oxidation furnace, the pre-oxidation furnace comprises a furnace body, an oxidation conveying unit used for conveying carbon fiber yarn from a furnace body inlet to a furnace body outlet is arranged in the furnace body and comprises two oxidation conveying chains extending in parallel, the two oxidation conveying chains are arranged at an interval in the horizontal direction to form a falling gap allowing the carbon fiber yarn to fall, the pre-oxidation treatment device further comprises upper support rods sequentially supported on the two oxidation conveying chains at intervals in the conveying direction of the oxidation conveying unit, and the upper support rod is used for supporting the carbon fiber yarn to allow the carbon fiber yarn falling from the falling gap to be arranged in the furnace body in a snakelike reciprocating way. The space of the carbon fiber yarn occupied in the pre-oxidation furnace is effectively improved, the utilization ratio of an internal space of the pre-oxidation furnace is effectively increased, and the volume of the pre-oxidation furnace is also reduced relatively.

Description

Technical field [0001] The invention relates to a continuous pre-oxidation treatment device and a pre-oxidation furnace. Background technique [0002] Carbon fiber is a new type of carbon material with a carbon content of more than 90% converted from organic fibers after a series of heat treatments. Carbon fiber not only has a series of excellent properties such as high conductivity, low expansion coefficient, high temperature resistance, corrosion resistance, creep resistance and self-lubrication, but also has the characteristics of fiber flexibility and weaving, and is often used as a reinforcement for advanced composite materials. It plays an irreplaceable role in aerospace and other national defense fields. At present, it is also widely used in civil industrial fields such as civil engineering and transportation. [0003] The carbon fiber preparation process is relatively complicated, and the main processes include polymerization, spinning, pre-oxidation, and carbonization. Ea...
