Problems solved by technology

[0004] However, the horizontal drying furnace occupies a large area, and the use of a horizontal drying furnace for drying has large smoke in the furnace and large water vapor at the furnace mouth (water vapor is easy to accumulate at the inlet and outlet, so it is easy to drip onto the fiber, which affects the quality of the product. Serious impact), poor drying effect, inseparable tow, etc., will eventually affect the appearance quality and performance indicators of the product

Embodiment 1

[0124] This embodiment provides a non-contact drying system for carbon fiber production, such as figure 1 As shown, the drying system includes a base, a vertical drying device arranged on the top of the base and connected to the base, a gas collecting device arranged above the vertical drying device, and a gas collecting device connected to the gas collecting device. Connected exhaust gas treatment unit.

[0125] The vertical drying device includes a housing and a conveying device at least partially arranged in the housing; the conveying device includes four driving rollers for conveying the fibrous material to be dried, wherein at least two of the driving rollers They are arranged outside the housing and respectively arranged on both sides of the base. Two transmission rollers are arranged inside the casing, the two transmission rollers are on the same plane, and are arranged at the top inside the casing; and the plane formed by the two transmission rollers is parallel to th...

experiment example

[0140] Observe and record the amount of water vapor at the inlet and outlet during the above drying process, and observe and record the state of the tow after drying. The results are as follows:

[0141] In Example 1: From the running state of the on-site tow, the inlet and outlet of the drying system (drying device) of Example 1 has no water vapor, and after the tow is dried by the drying system of Example 1, the surface of the carbon fiber material is hairless The silk is produced, the operation is stable, the drying effect is good, and the surface of the carbon fiber material has no color difference and no wrinkles.

[0142] In Comparative Example 1: Judging from the running state of the on-site tow, there is a large amount of water vapor at the inlet of the horizontal drying furnace of Comparative Example 1. After the tow is dried by the horizontal drying furnace of Comparative Example 1, the surface of the carbon fiber material has slight hairiness. Produced by silk, the ...

Abstract

The invention relates to the technical field of fibrous material production, in particular to a drying system, a fibrous material drying method and a carbon fiber production system. The drying system comprises a vertical drying device, a gas collecting device arranged above the vertical drying device, and a waste gas treatment device connected with the gas collecting device; the vertical drying device comprises a shell and a conveying device at least partially arranged in the shell. The conveying device comprises at least four transmission rollers, and at least two transmission rollers are arranged outside the shell. The shell is also connected with at least one hot air circulating device; and each hot air circulating device comprises a heater and a circulating fan. By arranging the vertical drying device, the drying stroke of the fibrous materials to be dried can be increased, the drying effect is improved, and the occupied area is saved. By arranging the gas collecting device and the waste gas treatment device, waste gas can be effectively sucked out and prevented from polluting fibrous materials, and environment protection is facilitated.

Description

technical field [0001] The invention relates to the technical field of fibrous material production, in particular to a drying system, a drying method for fibrous materials and a carbon fiber production system. Background technique [0002] Carbon fiber is a filamentous carbon material with excellent properties such as high specific strength, high specific modulus, high temperature resistance, corrosion resistance, heat transfer and small thermal expansion coefficient. Carbon fiber composite materials can not only carry loads as structural materials, but also play a role as functional materials. Therefore, the application of carbon fiber has developed rapidly in recent years, and has been widely used in many fields such as aerospace, automobiles, energy, construction, and sports equipment. [0003] In the production process of carbon fiber or other fibrous materials, increasing the feeding amount and increasing the running speed of the whole line are important means to incre...
