Panel waste recycling system and recycling method

Abstract

The invention discloses a panel waste recycling system and a recycling method, and belongs to the technical field waste recycling. The panel waste recycling system comprises a rack, a crusher, a loading machine and a conveying belt, wherein the crusher, the loading machine and the conveying belt are arranged on the rack; the crusher is used for crushing wastes; the loading machine and the conveying belt are used for conveying the crushed wastes; a ball grinder is connected to the tail end of the conveying belt; a stirring tank is connected to a discharge hole of the ball grinder; the crusher comprises a conveying roller for conveying the wastes, and a crushing box for crushing the wastes; a crushing shaft is arranged in the crushing box; multiple triangular crushing cutters are arranged onthe crushing shaft; the cross section of each triangular crushing cutter is of a triangular structure; and the crushing shaft penetrates through the center positions of the triangles. According to the panel waste recycling system provided by the invention, the wastes can be effectively crushed, the crushed wastes are then conveyed into tanks of the ball grinder, raw materials in each tank are ground independently, the quality of a slurry after grinding is high, the dosage in a high-compactness fiber cement panel can reach up to 15 percent, and the quality cannot be influenced.

Description

technical field [0001] The invention relates to the technical field of waste recycling, in particular to a board waste recycling system and recycling method. Background technique [0002] During the production process of fiber cement board, the size of the slab is generally 20mm larger than that of the finished board, resulting in a large amount of waste to be disposed of in the production of the board, coupled with some unqualified products, resulting in a large amount of waste in the production process of fiber cement board. Many companies ship it out as waste materials. Even though some companies are equipped with mills for grinding and recycling, the recovery rate is less than 50% due to various problems, and the quality of the grinding slurry is poor. Once the amount added exceeds 5% , will affect the quality of fiber cement boards, especially the quality of high-density fiber cement boards, so even powerful enterprises can only recycle a part or directly do waste treat...

Many companies ship it out as waste materials. Even though some companies are equipped with mills for grinding and recycling, the recovery rate is less than 50% due to various problems, and the quality of the grinding slurry is poor. Once the amount added exceeds 5% , it will affect the quality of fiber cement board, especially the quality of high-density fiber cement board, so even powerful enterprises can only recycle part or directly do waste treatment, and cannot achieve internal digestion and treatment of all waste scraps
