Description

Technical Field

[0001] The present invention relates to the field of fabric processing, and particularly to a high-temperature furnace device with tension needle rollers for fabric processing and its application. Background Art

[0002] Carbon fiber fabrics, carbon fiber felts, activated carbon fiber fabrics, activated carbon fiber felts, graphitized carbon fiber fabrics, and graphitized carbon fiber felts have important application values in many aspects such as fuel cell electrodes, all-vanadium redox flow battery electrodes, single-crystalline / multi-crystalline silicon manufacturing, adsorption materials, and medical and health care materials. These carbon fiber materials are produced through production processes such as pre-oxidation, carbonization, activation, and graphitization of organic fibers (such as polyacrylonitrile fibers, viscose fibers, phenolic fibers, etc.). Among them, carbon fiber fabric products are formed by cutting, spinning, and weaving continuous pre-oxidized fibers into organic fabrics, and then undergoing processes such as carbonization, activation, and graphitization; carbon fiber felt products are produced by needling organic fibers or pre-oxidized fibers into felts and then undergoing processes such as pre-oxidation, carbonization, activation, and graphitization.

[0003] In the practical application of carbon fibers, their mechanical properties are very important key parameters. In addition, there are also relatively high requirements for the uniformity of the physical properties of carbon fibers. A uniform wide width is very important in the practical application of carbon fiber fabrics and carbon fiber felts, especially in cases where the product is sold by area rather than by weight. A carbon fiber product with a uniform wide width can greatly increase economic benefits. Summary of the Invention

[0004] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a high-temperature furnace device with tension needle rollers for fabric processing and its application, which can significantly improve the mechanical properties and physical properties of carbon fiber fabrics.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] The inventors found that in existing continuous production devices for carbon fiber fabrics, carbon fiber felts, etc., it is generally completed through organic fiber inlet feeding control, in-furnace guide roller transmission, outlet stretching equipment, etc. In this way, only a certain tension can be applied to the fibers in the direction along the in-furnace guide roller transmission, that is, the warp direction, while there is no tension on both sides perpendicular to the in-furnace guide roller transmission direction, that is, the weft direction. The carbon fiber fabrics and carbon fiber felts obtained in this way have large differences in shrinkage rates in the warp and weft directions and large differences in mechanical properties in the warp and weft directions, and a wide-width carbon fiber fabric and carbon fiber felt cannot be obtained.

[0007] The inventor believes that in the preparation of continuous carbon fiber filaments or tows, under the action of drawing tension, the carbon fiber network plane can be repositioned and rearranged, the orientation angle can be reduced, and the orientation degree can be improved, thereby improving the elastic modulus. It is found that the tensile strength does not show an obvious pattern with the increase of tension. Therefore, applying tension can have an important impact on the structure, mechanical properties, etc. of carbon fibers. The following specific solutions are proposed:

[0008] A high-temperature furnace device with tension needle rollers for fabric processing. The device includes a heating furnace and a plurality of rotatable tension needle rollers arranged inside the heating furnace. There can also be round rollers. The tension needle rollers and round rollers are arranged side by side at intervals, and the rotation direction is the same as the fabric transmission direction. When in use, the fabric is placed on the tension needle rollers. The tension needle rollers are used to continuously transmit the fabric, and the tension needles on the tension needle rollers are used to uniformly apply tension to the fabric.

[0009] Furthermore, the tension needle roller is composed of a round roller and tension needles evenly distributed on the surface of the round roller. The outer diameter of the round roller is 40 - 150 mm, the inner diameter is 30 - 145 mm, and the spacing distance between the axes of the round rollers is 50 - 500 mm; the tip diameter of the tension needle is 0.05 - 3 mm, preferably 0.2 - 1.2 mm, and the length of the tension needle is 0.1 - 20 mm, preferably 0.5 - 3.5 mm. In short, the rotation between adjacent tension needle rollers does not conflict with each other.

[0010] Furthermore, the arrangement of the tension needles can be parallel, triangular, diamond-shaped or other arrangements, and the spacing between the tension needles is 0.05 - 50 mm, preferably 0.5 - 1.0 mm. The material of the tension needle can be metal, ceramic, oxide, etc., and the material is determined according to the use.

[0011] Furthermore, the tension needle roller is an integrally formed structure. It can be directly formed by lathe processing, rather than welding the needles to the round roller, which can ensure the strength of the tension needle roller during the heating process. The tension needle roller must be made of high-temperature resistant materials, such as Figure 3 .

[0012] Furthermore, the heating furnace is sequentially provided with a heating section, a constant temperature section and a cooling section along the fabric transmission direction; the heating section and the constant temperature section are provided with tension needle rollers, and the cooling section is provided with tension needle rollers and / or round rollers.

[0013] Furthermore, the length ratio of the heating section, the constant temperature section and the cooling section is (3 - 10):(2 - 20):(5 - 20).

[0014] Furthermore, the device further includes a fabric take-up mechanism for pulling the fabric, and the take-up mechanism is located outside the heating furnace; the device further includes a power mechanism for providing compensation power to the tension needle rollers; the inlet and outlet of the heating furnace adopt labyrinth seals to prevent air, oxygen, etc. from entering the furnace. The pulling speed is the same as or slightly less than the linear speed of the tension needle rollers.

[0015] An application of the high-temperature furnace device with tension needle rollers for fabric processing as described above. This device is used for fabric processing. The specific operation is as follows: Lay the fabric on the tension needle rollers, and then start the take-up mechanism, power mechanism, and heating furnace, continuously supply the fabric from the inlet of the heating furnace to complete continuous fabric processing.

[0016] Furthermore, the pulling speed and the linear speed of the tension needle rollers are 1 - 300 m / h, preferably 15 - 25 m / h, and the pulling speed is not greater than the linear speed of the tension needle rollers; the temperature distribution in the heating-up section is: increasing the temperature by 50 - 300 °C per 1 m distance, preferably: increasing the temperature by 70 - 150 °C per 1 m distance until it is the same as the temperature in the constant-temperature section, and the temperature in the constant-temperature section is set to 750 - 1200 °C; the atmosphere in the heating furnace is nitrogen, water vapor, or a mixture of nitrogen / water vapor.

[0017] Furthermore, the fabric includes carbon fiber fabric, carbon fiber felt, activated carbon fiber fabric, activated carbon fiber felt, graphitized carbon fiber fabric, or graphitized carbon fiber felt.

[0018] The prepared products such as carbon fiber fabric, carbon fiber felt, activated carbon fiber fabric, activated carbon fiber felt, graphitized carbon fiber fabric, and graphitized carbon fiber felt have characteristics such as high mechanical properties, high area yield, and uniform physical properties. They can also be used to produce other fiber fabrics.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] (1) In the present invention, by using a continuous transmission inner member device, carbon fiber fabrics with uniform shrinkage in the warp and weft directions, uniform surface density, wide width, and high breaking strength in the warp and weft directions can be obtained;

[0021] (2) In the present invention, using a continuous transmission inner member can significantly improve various physical properties of carbon fiber fabrics and carbon fiber felts;

[0022] (3) In the present invention, there are tension needles on the tension rollers. During the transmission of the fiber fabric or fiber felt, the tension needles randomly pierce into the fiber fabric or fiber felt, playing a role in limiting the free movement space of the fibers and applying tension, so that the tension applied in the warp and weft directions can be the same, the shrinkage ratio is the same, and the warp and weft directions of the fiber fabric or fiber felt shrink evenly.

[0028] The high-temperature furnace consists of three sections. The first section is the heating section, the second section is the constant-temperature section, and the third section is the cooling section. In the heating section, the temperature increases by 50 - 300 °C per 1 m distance incrementally, preferably by 70 - 150 °C per 1 m distance incrementally, and the length is selected as 3 - 10 m.
