Description

Technical Field

[0001] The utility model belongs to the technical field of glass fiber reinforced plastic recycling, and specifically relates to a crushing and screening device for waste glass fiber reinforced plastic materials. Background Art

[0002] Wind turbine blades are the core components of wind turbines that convert natural wind energy into electricity for wind turbines. As time goes by, the wind turbine blades that have been put into use in my country will face mass retirement. Due to the characteristics of their fiberglass composite materials and their large size, wind turbine blades need to be crushed for recycling.

[0003] The Chinese patent application number CN202121894135.9 discloses a waste wind turbine blade crushing and recycling device, including a box body, an inlet is provided at the top of the box body, a large particle discharge port and a small particle discharge port are provided at the bottom of the box body, a sliding frame is slidably connected to the top of the inner wall of the box body, a crushing wheel is provided inside the box body, and a vibration classification mechanism and a shaking cleaning mechanism are provided inside the box body. The utility model sets a vibration classification mechanism, starts the crushing wheel to crush it, and starts it at the same time of crushing, drives the rotating rod to rotate, and performs reciprocating swing vibration, so as to classify and filter the crushed residue falling on the filter net, so that the small particles are filtered to be discharged through the small particle discharge port, and the large particles are collected at the large particle discharge port and fall, so that the falling crushed residue is automatically vibrated and rolled down through the inclined surface and vibration, thereby accelerating the efficiency of classification and preventing excessive residue from clogging the filter net and causing the material to be unable to be discharged.

[0004] However, when the above device is actually used, when the crushing wheel crushes the fiberglass material in the sliding frame, the fiberglass material is easy to splash during the crushing process, which is not convenient for crushing and even more difficult to clean. Moreover, when the vibration classification mechanism screens the crushed material, the material is easy to slide directly from the inclined filter screen, resulting in poor screening effect.

[0005] In view of this, the present utility model is proposed. Utility Model Content
