Abstract
The utility model relates to a carbon fiber producing device, and in particular relates to a device for sizing carbon fibers. A sizing device for polyacrylonitrile carbon fibers comprises a sizing tank for holding a size. The sizing device for the polyacrylonitrile carbon fibers is characterized in that a guide roller partially infiltrated in the size and an immersing roller totally infiltrated in the size are arranged in the sizing tank, a return plate is arranged at the edge of an outlet of the sizing tank in an extending manner and an air blower is fixed above the return plate. The sizing device for the polyacrylonitrile carbon fibers guarantees the uniformity of the sizing amount on the surface of the carbon fibers by controlling the uniformity of the size on the surface of the carbon fibers.
Description
Technical field
The utility model is related to carbon fiber production apparatus, more particularly to a kind of quetsch for being used to carry out carbon fiber starching.
Background technology
Polyacrylonitrile carbon fiber has excellent mechanical property, it is used widely in aviation field, Leisure Sport articles for use and dual-use high-tech area, application in the infant industry field such as field such as bullet train, wind electricity blade, cable support core is also more and more extensive, important substance guarantee and promoting technology power that Yuhang aircraft develops to lightweight, high-performance and high reliability direction are had become, belongs to dual-use high-tech new material.
Polypropylene carbon fibers preparation process includes the processes such as polymerizable raw material, spinning, pre-oxidation, charing, surface treatment, starching and drying.Starching and drying are last procedures in carbon fiber preparation process, and the purpose of starching is to confer to carbon fiber convergence, wearability, water absorption resistance etc., is easy to the application of carbon fiber subsequently.
Starching uniformity, the width of carbon fibre tow and the appearance of carbon fiber have important influence to carbon fiber subsequent applications.If carbon fiber starching amount is uneven, carbon fibre tow width and appearance are irregular, when being manufactured into prepreg or being woven into fabric, its manufacturability can be poor, the form of prepreg and braid is difficult to precise control, and then influence the final performance for meeting material, the domestic carbon fibre of current domestic carbon fibre, especially greater than 12K, above mentioned problem is protruded very much, has become an important factor of restriction domestic carbon fibre quality.
Existing device for sizing is simple carbon fiber to be passed by from slurry, the surface of carbon fiber is set to have slurry, but the slurry of carbon fiber surface number and the thickness of slurry cannot control, cause the of poor quality of follow-up dried carbon fiber, it is impossible to meet the requirement of subsequent manufacturing procedures.
Utility model content
The utility model in view of the shortcomings of the prior art, devises that a kind of starch finishing effect is good, and the quetsch that can be controlled to the uniformity of carbon fiber surface slurry.
The utility model is achieved through the following technical solutions：
The quetsch of polyacrylonitrile carbon fiber, it includes the sizing groove for being used to hold slurries, it is characterised in that：Guide roller of the partial wetting in slurries and all submergence roller of the infiltration in slurries are provided with sizing groove, being extended in the outlet edge of sizing groove has back flow plate, and described back flow plate is fixedly arranged above air purging device.
Circulation line is provided with the outside of sizing groove, one end of circulation line and the bottom of sizing groove are connected, and the top edge of the other end and sizing groove is connected, and circulating pump is provided with circulation line.
In summary, the utility model has the advantages that:
The utility model is circulated in real time by the circulation line and circulating pump of setting to sizing liquor, ensure the uniformity of the sizing liquor in sizing groove, guide roller partial wetting remains the infiltration of sizing liquor, sizing liquor is prevented to form demulsification on the surface of guide roller, roll surface sudden strain of a muscle can be bonded in by forming the epoxy resin component after demulsification in sizing liquor, carbon fiber by when can form wrapping wire, the follow-up production of influence, the air purging device of setting can blow away the unnecessary sizing liquor of carbon fiber surface, it is improved the uniformity of carbon fiber surface slurries, back flow plate is used to the slurries blown down are continued to reclaim, make slurry reflux in sizing groove.
Brief description of the drawings
By detailed description below in conjunction with the accompanying drawings, the utility model is foregoing to be will become obvious with other objects, features and advantages.Wherein：
Fig. 1 show structural representation of the present utility model；
1 is circulation line in figure, and 2 be circulating pump, and 3 be guide roller, and 4 be submergence roller, and 5 be sizing groove, and 6 be air purging device, and 7 be back flow plate.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
The quetsch of polyacrylonitrile carbon fiber as shown in Figure 1, it includes the sizing groove 5 for being used to hold slurries, it is characterised in that：Guide roller 3 of the partial wetting in slurries and all submergence roller 4 of the infiltration in slurries are provided with sizing groove 5, being extended in the outlet edge of sizing groove 5 has back flow plate 7, and described back flow plate 7 is fixedly arranged above air purging device 6.
The outside of sizing groove 5 is provided with circulation line 1, and one end of circulation line 1 is connected with the bottom of sizing groove 5, and the other end is connected with the top edge of sizing groove 5, and circulating pump 2 is provided with circulation line 1.
In summary, the utility model has the advantages that:
The utility model is circulated in real time by the circulation line and circulating pump of setting to sizing liquor, ensure the uniformity of the sizing liquor in sizing groove, guide roller partial wetting remains the infiltration of sizing liquor, sizing liquor is prevented to form demulsification on the surface of guide roller, roll surface sudden strain of a muscle can be bonded in by forming the epoxy resin component after demulsification in sizing liquor, carbon fiber by when can form wrapping wire, the follow-up production of influence, the air purging device of setting can blow away the unnecessary sizing liquor of carbon fiber surface, it is improved the uniformity of carbon fiber surface slurries, back flow plate is used to the slurries blown down are continued to reclaim, make slurry reflux in sizing groove.
The utility model is not limited to described embodiment, and those skilled in the art is not being departed from the i.e. open scope of spirit of the present utility model, can still make some amendments or change, therefore rights protection scope of the present utility model is defined by the following claims.
