Spouting fluidization machine and method for producing multi-scale solid mixtures

Abstract

The invention belongs to the technical field of fluidization. A spouting fluidization machine comprises a cylinder, a conical distributor, a stirring device, a discharge system and a pipe cutting machine; a feed inlet and a discharge outlet are arranged in the side wall of the cylinder, and the discharge outlet is located above the feed inlet; the conical distributor which is of a double-layer structure is mounted on the lower portion of the cylinder and comprises an outer conical shell and an inner conical body, a plurality of distributing holes for distributing gas are formed in the inner conical body, a fluidization gas pipeline is connected to the lower end of the outer conical shell, and a sprouting gas pipeline is connected to the lower end of the inner conical body and is arranged in the fluidization gas pipeline and is coaxial to the same; the stirring device comprises a stirring shaft motor and a stirring wheel which penetrate the end socket of the cylinder; a sprouting pipe is arranged in the cylinder with the upper end located right under the stirring wheel and the lower end extending into the cavity of the inner conical body, and the pipe cutting machine is mounted at one end of the sprouting gas pipeline. By the arrangement, multi-scale solid phase can be efficiently dispersed and mixed and conveyed in network to obtain products evenly and stably dispersed and mixed.

Description

technical field [0001] The invention belongs to the technical field of jet fluidization. Background technique [0002] Composite materials have been widely used in various fields due to the synergistic effect between the various components, which greatly improved their corresponding mechanical and physical properties. Fiber-reinforced composites are an important member of the composite material family. In the preparation of fiber-reinforced composite materials, according to the process requirements, it is necessary to impregnate and shape the fibers of various shapes and weaves and the reinforced matrix (referred to as the matrix). One of the products needs to cut the continuous fiber into a certain length. The chopped fibers are used to make composite materials. This process requires cutting, dispersing and mixing the fibers with the matrix before impregnating and shaping them. From a technical and economic point of view, this process can and needs to realize the continu...

AI Technical Summary

Problems solved by technology

The fiber cutting machines disclosed above all use the gravity of the fibers to collect the chopped fibers, and then feed them into the fluidization equipment for dispersion. Since the chopped fibers have a lighter gravity, they are not easy to separate from the cutting machine. In addition, if the length and diameter of the fibers after chopping are relatively large, it is easy to cause intertwining and knotting between the fibers, which is not conducive to subsequent fluidization and dispersion.
