Title:
STIRRING AND SEPARATING DEVICE FOR HIGH-VALUE COMPONENTS OF WASTE PCB, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/173892
Kind Code:
A1
Abstract:
A stirring and separating device for high-value components of a waste PCB, and a control method. The stirring and separating device comprises an outer insulated tank (1), wherein a stirring mechanism (8) is arranged inside the outer insulated tank (1), and comprises a primary rotary shaft (801); several cross beams (803) are mounted at the bottom of the primary rotary shaft (801); a secondary rotary shaft (802) is mounted on each cross beam (803); the bottom of each secondary rotary shaft (802) is rotatably connected to a stirring wheel (805) by means of at least two connecting rods (804); at least two connecting points are formed between the connecting rods (804) and the stirring wheel (805); and when any one or more connecting points are disconnected, the stirring wheel (805) can rotate to different angles. High-value components on a PCB are separated by using deflux, thereby solving the problems of environmental pollution and resource waste caused by existing waste PCB recycling methods; and the direction of the stirring wheel (805) can be controlled by controlling the connection or disconnection between the connecting points between the connecting rods (804) and the stirring wheel (805), such that the deflux comes into full contact with a waste PCB, thereby accelerating the separation of the high-value components on the PCB, and improving the separation efficiency.
