(1). Project Overview
Carbon fiber is a new type of fiber material with high strength and high modulus fiber containing more than 95% carbon. It is a microcrystalline graphite material obtained by stacking organic fibers such as flake graphite microcrystals along the axial direction of the fibers, and subjected to carbonization and graphitization treatment. Carbon fiber is "soft outer and inner rigid", which is lighter than metal aluminum, but stronger than steel, and has the characteristics of corrosion resistance and high modulus. It not only has the inherent intrinsic characteristics of carbon materials, but also has the soft processability of textile fibers, and is a new generation of reinforcing fibers.
Carbon fiber carbon materials have been widely used in various fields of military and civil industries. From civil industries such as aerospace, aviation, automobiles, electronics, machinery, chemicals, and textiles to sports equipment and leisure products. Carbon fiber-reinforced composite materials can be used in military fields such as aircraft manufacturing, industrial fields such as wind power blades, electromagnetic shielding static elimination materials, artificial ligaments and other body substitute materials, as well as for manufacturing rocket shells, motor boats, industrial robots, automobile leaf springs Drive shaft, etc. Carbon fiber is a typical new industrial material in the high-tech field.
For the drying of carbon fiber, the difficulty is that the temperature control of the partition must be accurate and uniform. Our engineers and the technicians of the company have also conducted many exchange experiments on these parameters, and finally obtained an ideal and satisfactory result. The set of carbon fiber drying system includes horizontal three-layer drying furnace, main fan, exhaust fan, circulating pipeline, thermal resistance field junction box, etc., which contains two independent hot air circulation systems, each temperature zone is set with 4 measurement The temperature point is convenient for customers to observe and adjust.
(3). Engineering principles
When drying, the hot air is forced from the top and bottom of the material to make every particle surface become the heating surface. Increasing the contact area between the material and the hot air significantly increases the heat conduction area and shortens the water diffusion distance inside the material. Therefore, the drying operation with excellent effect can be carried out, especially for the dried materials after adding proper preparation forming. Therefore, the selection of this series of dryers has the advantages of high stability and energy saving.
(4). Engineering characteristics
Air volume, heating temperature, material residence time and feeding speed can be adjusted to achieve the best drying effect.
The equipment configuration is flexible, and the mesh belt flushing system and material cooling system can be used.
The operation is flexible. After the wet materials enter the machine, the drying process is carried out in a completely sealed box. The labor conditions are good and the leakage of dust is avoided.
When the dried material moves with the conveyor belt, the relative position between the material particles is relatively fixed, with basically the same drying time, which is very suitable for certain drying processes where the color of the material changes or the moisture content requires uniformity. In addition, the material is subjected to The vibration and impact are very slight, and the material particles are not easy to break, so it is also suitable for drying some materials that are not allowed to break.
Not only can the materials be dried, but sometimes they can be baked, cooked or cooled.
The unique air distribution device makes the hot air distribution more uniform, ensuring the consistency of product quality.
The structure is simple, the installation is convenient, and it can be operated for a long time. When a fault occurs, it can be accessed to the inside of the cabinet for maintenance, which is convenient for maintenance.
