Description
Technical Field
The invention relates to a paper-surface gypsum board technology, in particular to a method and a device for recycling paper-surface gypsum boards.
Background
At present, gypsum board enterprises at home and abroad adopt corresponding measures to recycle gypsum boards with waste paper surfaces so as to achieve the purposes of reducing environmental pollution and wasting resources. The method for recycling the paper-surface gypsum board mainly comprises the following two methods: one is to burn the waste gypsum board to remove the outer protective paper, then to crush the waste gypsum board for reuse, but this method cannot use the outer protective paper and the burning will cause pollution; the other method is to carry out crushing operation on the gypsum board, further separate the gypsum core from the protective paper and reuse the gypsum core for manufacturing the gypsum board, thereby reducing the environmental pollution and the production cost.
Correspondingly, aiming at the recycling method, special mechanical equipment is developed at home and abroad to realize the recycling treatment of the waste gypsum boards. For example, GYPchipper is adopted in America, the crushing mode is single-shaft rotary spike pin crushing, and the crushing capacity is 2.5 t/h. A chopper, a chopper type cutter, which is developed in Japan and is suitable for processing waste gypsum boards at the construction site, is constituted by crushing with a double-shaft rotary meshing blade and has a crushing capacity of 1.5 t/h. A gypsum recovery system designed and developed by EGRS of the subsidiary of the Enviro Grind group of Ireland consists of a vibrating screen, a mill and a belt conveyor. The process crushes the waste gypsum and the waste gypsum board, separates the protective paper, and grinds the gypsum into powder, so that the gypsum can be applied to the gypsum board industry, the agricultural field, the cement industry and the like again.
At present, equipment for treating waste materials in construction sites is also developed correspondingly in China, for example, a PS-Phi 380X 280 small hammer mill designed and manufactured by Changzhou construction machinery repair shops crushes waste gypsum boards by utilizing a fast rotating hammer, is only suitable for small plates, waste materials and the like, and has the crushing capacity of 1 t/h. The new group building materials company Limited develops a roller crusher to be used together with other auxiliary equipment to crush and recycle waste gypsum boards. The auxiliary equipment mainly comprises a belt conveyor, a vibrating screen, a dust collector and the like. The process arrangement can be carried out according to the conditions of the existing site and the used equipment. The working principle of the system is that the roller type tooth-shaped crusher crushes and crushes the waste gypsum boards into crushed materials and recycles the crushed materials, the crushing capacity is about 2.5t/h, the effect is good, and the influence on the environment is reduced. Zhaqing north new building materials limited company adopts a shear type crusher, gypsum boards with waste paper surfaces are uniformly distributed in the space between a rotor and a stator toothed plate through a distributing cone, materials are crushed by the extrusion and shearing of the rotor toothed plate and the stator toothed plate, the crushed materials and pre-screened materials are discharged from the bottom of the crusher, the crushing capacity is about 2.5t/h, and the method can crush flexible face protection paper and brittle gypsum.
The waste gypsum boards are mainly classified into standard-width gypsum boards and small boards (gypsum filler strips, etc.). The waste gypsum board is treated by a one-step crushing method by integrating the treatment processes at home and abroad. If only one-step crushing method is adopted for treatment, the paper after crushing is not completely separated from the gypsum, and the paper cannot be directly recycled in production, so that grinding and screening equipment is required to be added in subsequent raw material production equipment to be practical and feasible.
