[0001] The invention belongs to the technical field of wood fiber transportation, and in particular relates to a wood fiber wind transportation device and a transportation method. Background Art

[0002] Wood fiber is a mechanical tissue composed of lignified thickened cell walls and fiber cells with fine crack-like pits. It is one of the main components of xylem. The wood fiber used in the textile and garment industry is viscose fiber transformed from wood pulp through a production process. It is a cellulose fiber. It is made by crushing the wood, steaming it at high temperature to make wood pulp, removing the sugar and fat in it, and finally extracting plant cellulose and reshaping its cellulose molecules to obtain textile raw materials.

[0003] Since wood fibers contain a certain amount of moisture, it will not only affect the fluidity of the wood fibers but also the efficiency of wind transportation. In addition, too much moisture may also cause the wood fibers to agglomerate, resulting in accumulation and blockage of the wood fibers during the transportation process.

[0004] To this end, we provide a wood fiber wind conveying device and a conveying method to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a wood fiber wind conveying device and conveying method, by setting a heating device to dry the wood fiber, and the rotating shaft and the rotating shaft drive the first striking block and the second striking block to rotate, the first striking block and the second striking block are intertwined with each other, and the agglomerated wood fibers are broken up, thereby solving the problem that the existing wood fiber moisture is too high and affects the wind conveying efficiency.
