Extra-large drying oven structure provided with carbon fiber barrel

Abstract

The invention discloses an extra-large drying oven structure provided with a carbon fiber barrel. The structure comprises a rack and sliding rails arranged in the rack. A drying oven is arranged at the upper end of the rack. A drying cavity is formed in the drying oven. A ladder is arranged on the drying oven. Heated air circulation side air ducts are symmetrically formed in the two sides of the interior of the drying oven. The upper ends of the two heated air circulation side air ducts communicate with each other through a heated air circulation upper air duct formed in the upper end of the drying oven. The lower ends of the heated air circulation side air ducts are provided with heated air circulation air outlets communicating with the drying cavity. A heated air circulation air return port communicating with the drying cavity is formed in the middle of the heated air circulation upper air duct. A plurality of heating units are uniformly arranged in the positions, at the upper ends of the heated air circulation side air ducts, of the drying oven correspondingly.

Description

technical field [0001] The invention relates to a drying device, in particular to a super large oven structure of a carbon fiber cylinder. Background technique [0002] Carbon fiber tubes are widely used in the aerospace field. Carbon fiber is a material that is stronger than steel and lighter than aluminum. It has many advantages in mechanics, electricity and heat. It also has excellent electrical conductivity and anti-magnetization. , high temperature resistance and chemical corrosion resistance, it is considered to be an advanced material with the best comprehensive performance. At present, gluing and drying are required in the production process of carbon fiber cylinders, and the length of carbon fiber cylinders is between 14 and 15 meters, and the diameter is about 5 meters.

AI Technical Summary

Problems solved by technology

At present, gluing and drying are required in the production process of carbon fiber cylinders, and the length of carbon fiber cylinders is between 14 and 15 meters, and the diameter is about 5 meters. The following disadvantages: 1. The carbon fiber cylinder drying equipment currently used is directly heated by the electric heating tube, the heating is uneven, the temperature difference between various parts inside the drying equipment is large, and the drying effect is poor; 2. The drying equipment The temperature cannot be uniformly cooled at the same interval time, the temperature control cannot meet the requirements, and the cooling effect is poor; 3. The observation windows on the existing drying equipment are all single-layer tempered glass wrapped by inner and outer fixing rings, which have poor sealing performance and are easy to Lead to heat loss; 4. Once people are locked in the existing carbon fiber cylinder drying equipment, it is difficult to escape, and the safety performance is poor; 5. The existing drying equipment is directly driven by a geared motor to rotate the carbon fiber cylinder for drying. Only relying on the geared motor to drive is likely to cause vibrations during the rotation of the carbon fiber cylinder, and even distort and deform the motor shaft of the geared motor, thereby damaging the

[0003] The geared motor is damaged, resulting in damage to the drive device; 6. Every time carbon fiber tubes of different specifications are connected to the carbon fiber tube drive device, the positions of the respective connecting flanges must be adjusted repeatedly, and the installation is time-consuming and laborious; 7. The existing carbon fiber tube mobile conveyor frame The length of the carbon fiber tube cannot be adjusted, and it cannot adapt to carbon fiber tubes of different lengths, and the scope of application is small; The bearing seat is installed on the mobile conveyor frame above, which takes a long time for hoisting, troublesome installation, and unstable support; 9. When the existing mobile conveyor frame transports the carbon fiber tube to the oven, due to the mechanical inertia, the conveyor frame is easy to contact with the inner wall of the oven. Collision occurs, the transportation is unsafe, and at the same time, the conveyor chain is prone to breakage under the action of starting tension and mechanical inertia, and maintenance is frequent. In addition, the mobile conveyor frame cannot be effectively fixed on the frame, and it is easy to change on the track location, there is a security risk
