Glass fiber reinforced plastic decomposition and recovery equipment and recovery method

Abstract

The invention relates to the technical field of glass fiber reinforced plastic recovery, in particular to glass fiber reinforced plastic decomposition and recovery equipment and a recovery method. The glass fiber reinforced plastic decomposition and recovery equipment comprises a grinding device, a high-temperature heat treatment device, a cooling device, a dust removal device and a catalysis device. The grinding device comprises a base, a rotating cylinder, a grinding ring groove body, a feeding hopper, a grinding cylinder and an adjusting device. An annular grinding cavity with an upward opening is defined in the grinding ring groove body, and a discharging opening is formed in the bottom of the grinding ring groove body. The grinding cylinder is arranged in the grinding cavity and comprises a plurality of grinding plates, a plurality of first hinge shafts and a plurality of second hinge shafts. The adjusting device comprises a sliding ring, an elastic rope, a plurality of first connecting rods, a plurality of second connecting rods and a plurality of third connecting rods. During normal work, the lower end of the feeding hopper is opened, the lower end of the feeding hopper is closed when the feeding hopper is clamped, the grinding cylinder is in a dynamic change process in the grinding process and cannot be clamped till glass fiber reinforced plastic waste is ground to the preset size, manual unclamping is not needed, and the grinding efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced plastic recycling, in particular to a glass fiber reinforced plastic decomposition recovery equipment and recovery method. Background technique [0002] Fiberglass reinforced plastic (FRP) is also known as GFRP, namely fiber reinforced plastics, generally refers to glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix, glass fiber or its products as reinforced plastics, called glass fiber Reinforced plastic, or FRP, is different from tempered glass. Due to the different types of resins used, there are polyester FRP, epoxy FRP, and phenolic FRP. Light and hard, non-conductive, stable performance, high mechanical strength, less recycling, corrosion resistance. It can replace steel to manufacture machine parts, automobiles, ship shells, etc. [0003] When recycling waste FRP, the large pieces of FRP are pretreated by using a shredder, and then the FRP i...
