Description

But material recycle's screening plant Technical Field The invention relates to the technical field of screening, in particular to a screening device capable of recycling materials. Background In the field of solid waste recycling, the large-scale treatment and recycling of carbon fiber reinforced composite materials have become key links of new material industry chains. After preliminary mechanical stripping, physical comminution or specific process treatments, the recovered material exhibits a highly heterogeneous and complex mixing morphology. Such materials are generally composed of a particulate matrix powder of micron order together with a needle-like or rod-like hard phase having a high aspect ratio, such as residual carbon fiber filaments, strands or fiber reinforcement phases. In this recycled mixture, the acicular or rod-like hard phases have remarkable physical geometrical characteristics, with small cross-sectional diameters and large longitudinal lengths. The long and thin needle-shaped hard phases are extremely easy to generate random physical interweaving and layer-by-layer entanglement in the material stacking process under the comprehensive influence of physical properties of the surfaces of the fibers, electrostatic adsorption or residual bonding components, so that the long and thin needle-shaped hard phases are evolved into a mixed dough which takes the fibers as a framework and is wrapped by fine powder. The dough structure is stable in property and has obvious anisotropism. The physical behavior of the mixture, when it is in the sieved state, shows extreme instability. The spatial attitude of the needle-like or rod-like hard phase when entering the sieve pores directly determines the sieving effect due to the aspect ratio characteristics of the needle-like or rod-like hard phase. When the needle-shaped hard phase contacts the screen surface in a horizontal or horizontal posture, the needle-shaped hard phase is very easy to cover and shield the mesh to form physical barrier, so that the normal passing of the powdery main material is blocked, and when the needle-shaped material is in a vertical posture in vibration or flow, the fine section diameter of the needle-shaped material is very easy to enable the needle-shaped material to pass through the mesh holes along with the powder particles directly to enter a finished product stream. In addition, a large amount of fine powder tends to sink deeply into the inter-hook fiber interstices, and these particulate host materials are firmly held within the fiber skeleton due to lack of sufficient displacement space and efficient directional alignment. In conventional material level movement, this entanglement causes the material to exhibit an integral agglomeration phenomenon. At this time, the needle-shaped hard phase tends to randomly deflect and break in the material layer, and the geometric size difference between the broken short needle-shaped material and the powder is further reduced, so that the two types of materials which should be separated originally are highly overlapped in spatial distribution, and a hybrid state which is difficult to naturally classify through physical displacement is formed. The random orientation of the needle-shaped hard phase and the coating effect of the dough form an objective pattern with limited physical separation efficiency.
