New description: [New technical field] This creation belongs to the field of carbon fiber pre-oxidation technology, especially refers to a new design of vertical air-path carbon fiber oxidation furnace structure, which can make carbon fiber filaments evenly heated and meet the processing technology theory. The carbon fiber filament can quickly exchange heat, heat the inner layer, not ignite due to the inner layer heat accumulation, and has the functions of lateral temperature uniformity, longitudinal temperature uniformity, free relaxation of carbon fiber filaments, low residence time, low retention distance and high yield. [Prior Art] According to the 'carbon fiber', the first of the two major groups in the 1950s, the United States and the Soviet Union, in order to watch the game, a lightweight and mechanically strong material, carbon fiber was born. Carbon fiber was not developed at that time. According to the literature, in the early years of the invention of the king, Edison wanted to find a kind of filament that was resistant to high temperatures and could be energized. He used bamboo fiber to burn it into a carbon fiber pattern for use as a filament. However, the carbon fiber he made is too brittle and has no strength at all, although it can be used for power-on lighting. There is still a distance from the real practical point. Once the crane was successfully developed, the use of carbon fiber as a filament was immediately abandoned. Polyacrylonitrile is the main secret of manufacturing rhyme. The world's production of carbon fiber is 80% and 90% from polyacrylonitrile. Therefore, the manufacturing, spinning and subsequent sintering process of polypropylene riding - cyclization, carbonization and graphite 彳#important. The most excellent properties of carbon fiber are the reinforcing fibers with specific strength and specific modulus. The specific strength and specific modulus of the composites formed with the resin are about 3 times higher than that of steel and alloy. Carbon fiber composites are used in spacecraft, missiles and aircraft to significantly reduce weight and improve the effective performance of 'improving performance'. Due to the cost reduction, M324188 carbon fiber has been gradually expanded for use in the civil industry, such as the automotive industry and sports equipment: carbon fiber is pre-oxidized, carbonized and graphitized after a predetermined period of time at a predetermined tension temperature. Process made. The purpose of pre-oxidation is to transform the linear macromolecular chain of the layer of raw silk into a heat-resistant ladder structure after being treated, which is insoluble and incombustible, and can withstand high temperature carbonization and lay age. The key device for realizing this-transformation is the pre-oxygen dumping research handle. Wei-dipping must first meet the requirements of the process conditions. That is, the temperature field of the heating system is uniform and the temperature gradient distribution is reasonable. The airway method of the conventional carbon fiber oxidizing furnace is to be horizontally blown and exhausted in the horizontal direction above and below the carbon fiber filaments, and then modified to provide a layer-guided wave plate between each of the upper and lower carbon fiber filaments according to the above manner. To form a small blowing angle. However, the above-mentioned square way makes the carbon fiber oxidizing furnace blow to the carbon fiber filament at a horizontal or small angle due to the hot air system, which is not in accordance with the treatment technology theory, and generally has a poor heat exchange rate of the inner layer of the carbon fiber filament, a slow heat exchange rate, and an easy accumulation of the inner layer. When the heat is ignited, the horizontal and longitudinal uniformities of the carbon fiber filaments are poor, and the carbon fiber filaments have a long residence time and a large distance, and the productivity is low. This is the biggest loss of the current conventional technology, and this lack is a difficult problem to be overcome in the industry. [New content] In view of the lack of conventional technology, this creative researcher has accumulated many years of experience in the design and manufacture of carbon fiber production equipment. After continuous research and improvement, the creation of this creation has been successful and made known to the world. The reason is that the main purpose of this creation is to provide a "vertical wind-type carbon fiber oxidizing furnace" which is mainly used on the carbon fiber filaments in the oxidizing furnace, and has dense and vertical hot air blowing holes and vent holes on the lower two sides. The dense circulating hot air is blown to the carbon fiber M324188 in the vertical direction to make the carbon fiber filaments evenly heated. According to the theory of processing technology, it can quickly exchange heat, heat the inner layer, not ignite heat, and have lateral temperature uniformity y The average temperature and carbon fiber can be self-sufficient, low __, retention distance, high yield and so on. [Embodiment] In order to achieve the above-mentioned technical purpose of the present invention, an embodiment will be described, and with reference to the following description, the reviewing committee can obtain a better understanding of the structure, features and functions achieved by the reader. As shown in the first-®, this creation is mainly based on the carbon fiber filaments (1) in the oxidation furnace, and the dense and vertical hot air blowing holes (2〇) and the exhaust holes (3〇) on the lower two sides, and the oxidation furnace circulation hot air flows through The air pipe (2) is blown out by the air blowing hole (2〇) [please refer to the drawing cycle blowing direction (A)], and the exhaust gas is exhausted by the exhaust hole (3〇) through the circulating exhaust pipe (3) [please refer to the figure Circulating exhaust direction (B)], blowing carbon fiber filaments (1) in a vertical direction by dense circulating hot air, so that the carbon fiber filaments are evenly heated, in accordance with the treatment technology theory [process heat is exothermic reaction], so carbon fiber filament energy is required Rapid heat transfer, inner layer heat transfer, right angle or large angle blowing can be achieved through the interface mechanism and forced heat transfer mechanism to effectively achieve rapid heat transfer and inner layer heat transfer of carbon fiber. The traveling direction (C) of the carbon fiber filament (1) and the hot air blowing direction (A) are perpendicular and densely arranged, so that the temperature of each wind receiving point of the carbon fiber filament (1) is the same, and the vertical hot air can be The carbon fiber filament (1) is blown through, so the carbon fiber filament can quickly exchange heat, heat the inner layer, not start from the inner layer of heat, and has lateral temperature uniformity, longitudinal uniformity, and carbon fiber filament can be freely relaxed and low. Retention time, low retention distance, south production and other effects. In this way, the purpose of this creative design is called a practical creator of M324188. In summary, this kind of "vertical wind-type carbon fiber oxidizing furnace" disclosed by the creator has never been seen in the publications published at home and abroad, and it has already had new patents, and the creation is indeed ageing. The lack of customary technology and the achievement of design purposes have also fully complied with the new type of "professional _" for women, and submitted an application in accordance with the law. "Please ask your review board to give a review and give this case the exclusive The above is only for the purpose of this creation - the preferred use of H has been used to limit the scope of this creation.
