Problems solved by technology

[0002] Valuable metals in waste circuit boards are pretreated and multi-stage crushed to obtain powdery materials, and then sorted by airflow separators to obtain valuable metal (copper) powders. Because the existing airflow separators Edge feeding is adopted, and the materials are broken up and dispersed by the spreading plate and the buffer plate. The position of the feeding port is close to the edge of the spreading plate, which leads to uneven distribution of the material on the circumference of the grading area, and the separation If the selection is appropriate, when the material distributed through the spreading plate is rotated and spilled, because it also contains resin components, a small amount of metal powder and resin powder will stick together, and the problem of low efficiency in the separation of valuable metals

Abstract

The invention discloses an efficient environment-friendly recycling system for valuable metals of a waste circuit board. The system structurally comprises a dust outlet, a feeding port, a first discharging port, a machine body, a second discharging port, supporting legs, a motor, a central feeding structure, a magnetic attraction strip and a material scattering disc, wherein the dust outlet is installed at the topmost end of the machine body, the feeding port is formed in the side surface of the machine body, and the scattering disc is arranged in the middle of the interior of the machine body. According to the system, through mutual cooperation of an inclined plate and the material scattering disc, the inclined plate rotates to gradually drive materials to slide down and fall from the discharging pipe to the center of the material scattering disc, the material scattering disc rotates to scatter the materials from the center, and the scattering is more uniform; and through the design of the discharging pipe and a material guiding ring on the same axis, the materials falling from the discharging pipe are precisely located in the material guiding ring, the materials are located in the middle of a disc, the disc is driven by the motor to rotate at a constant speed, and the materials located in the material guiding ring are uniformly spread out.
