Gypsum board waste crushing and separating device

Abstract

The invention discloses a plasterboard waste crushing and separation device which comprises a machine body, wherein an inclined feed port is formed at the top of the machine body; the bottom end of the inclined feed port is connected with a crushing housing; a conveying belt component is arranged at the bottom of the crushing housing; a plurality of hammerhead crushing structures are arranged at the top of the crushing housing; rotary tillage crushing structures are arranged between the adjacent hammerhead crushing structures; an inclined guide port is connected with one side of the crushing housing; a separation drum is connected with the bottom end of the inclined guide port; an unloading housing is arranged outside the separation drum; uniformly distributed small holes are formed in the surface of the separation drum; and a discharge port is connected with the bottom end of the unloading housing. The device has a better crushing effect; recycling can be performed without secondary crushing; the crushing workload is reduced; at the same time, surface protection paper can be crushed into paper scrap and separated; blocking of the discharge port can be avoided; and in addition, the device is more suitable for crushing of plasterboards by adjusting the feed port.

Description

technical field [0001] The invention relates to the field of gypsum boards, in particular to a device for crushing and separating gypsum board waste. Background technique [0002] Gypsum board is a material made of building gypsum as the main raw material. It is a building material with light weight, high strength, thin thickness, convenient processing, sound insulation, heat insulation and fire resistance. One of the new lightweight panels. Gypsum boards have been widely used in interior partition walls, wall cladding panels (replacing plastering layers), ceilings, sound-absorbing panels, ground floor panels and various Decorative panels, etc., for indoor use should not be installed in the bathroom or kitchen. [0003] During the production process of gypsum board, due to equipment, electrical or process factors, gypsum board waste will be generated. For example, the second-controlled waste gypsum board and the third-control damaged board are all gypsum waste, and a large...

AI Technical Summary

Problems solved by technology

[0006] (1) Since the gypsum board waste itself has a high viscosity, a certain strength and has a protective paper, it is easy to cause the discharge port to be blocked when it is crushed, and the protective paper will come out in pieces, which cannot meet the recycling requirements ;

[0007] (2) The pulverizing efficiency of existing pulverizer that is used for gypsum board is low, and pulverizing effect is poor, and the particle after pulverizing is bigger, needs to carry out secondary pulverizing usually, has strengthened the workload of pulverizing;

[0008] (3) The gypsum board waste is lumpy, but the diameter of the feed port of the existing pulverizer is too small, which is easy to cause blockage, requires a lot of manual cleaning, and the manual operation of the feed port is difficult, which affects the efficiency of crushing
