Abstract
Description
Technical Field
[0001] The utility model relates to a heating device for a steam pipeline used in carbon fiber production, belonging to the technical field of heating of carbon fiber steam pipelines. Background Art
[0002] In the existing carbon fiber production process, steam drawing of precursor is a very important link, which has extremely high technical content and determines the final quality of carbon fiber. Therefore, the quality of steam directly affects the quality of precursor. However, the steam in the steam pipeline currently contains a large amount of condensed water. It is only treated by heat preservation and steam traps installed outside the pipeline. The heat loss of steam is large and condensed water is easy to be generated. When the precursor is steam-drawn, it is easy to cause broken wires, fluffing, and roller entanglement, which causes many adverse effects in production, not only affecting the final quality of carbon fiber, but even making normal production impossible.
[0003] In order to remove condensed water in steam, the existing steam drawing machine installs a gas-liquid separator or a steam trap at the end pipeline of the steam drawing machine to remove condensed water in the steam. However, this will cause steam loss and temperature drop, and the effect is not ideal.
[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
[0005] In view of the deficiencies in the background technology, the utility model provides a heating device for a steam pipeline for carbon fiber production, which can remove condensed water in water vapor, improve the effect of steam drawing of precursor yarn, ensure the quality of carbon fiber, ensure steam temperature, and save steam.
[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0007] A heating device for a steam pipeline for carbon fiber production comprises a steam pipeline, a first induction coil is wound around the outside of the steam pipeline, an annular gap is formed between a circular coil formed by the first induction coil and an outer wall of the steam pipeline, a plurality of support bars are arranged in the annular gap along the axial direction of the steam pipeline, and the support bars fix and support the first induction coil outside the steam pipeline;
[0008] The input and output terminals of the first induction coil are connected to a controller, and the controller controls the magnitude of the coil current, thereby controlling the strength of the electromagnetic heating.
[0009] Furthermore, a temperature sensor is provided at the discharge end of the steam pipe to detect the steam temperature, and the temperature sensor transmits a temperature signal to the controller.
[0010] Furthermore, the diameter of the circular coil formed by winding the first induction coil is 2 cm larger than the diameter of the steam pipe.
[0011] Furthermore, a second induction coil and a third induction coil are wound around the outer side of the steam pipe.
[0012] Furthermore, the first induction coil, the second induction coil and the third induction coil are arranged along the axial direction of the steam pipe.
[0013] Furthermore, a plurality of support bars are provided between the second induction coil and the outer wall of the steam pipe and between the third induction coil and the outer wall of the steam pipe, and the plurality of support bars are evenly distributed around the circumference of the steam pipe.
