The invention discloses a wind
turbine blade
material degradation and recycling device in the technical field of wind
turbine blade recycling, comprising a preheating tank and a
Stirling engine, wherein the inner wall of the preheating tank is provided with a preheating chamber; the input end of the
Stirling engine is connected with the preheating chamber, and the output end of the
Stirling engine is provided with a crushing mechanism for crushing the wind
turbine blades; a wind selection mechanism for screening wind
turbine blade fragments is provided below the preheating tank, the wind selection mechanism comprises a base, a wind selection channel and a wind selection chamber are provided in the base, a
recovery plate is provided in the wind selection chamber, a plurality of screening holes are provided on the
recovery plate, and the screening holes are successively reduced in order from top to bottom; a fan is provided on the side of the
recovery plate away from the wind selection channel, a heating chamber is further provided below the recovery plate, and an insulating mechanism for sealing the heating chamber is provided between the heating chamber and the recovery plate; the
reuse rate of
heat energy is improved by the Stirling engine and the wind selection mechanism, the wind turbine blades are preheated, and the
processing efficiency of the blades is improved.
