Embodiment Construction

[0022] Such as Figure 1-3 As shown, in the waste circuit board metal recovery device based on high-frequency induction heating described in the embodiment of the present invention, after the motor drives the crucible (12) to rotate, the induction coil (1) is energized, and the waste circuit board fragments in the crucible (12) The metal on (13) induces heat under the action of electromagnetic induction, and clings to the inner wall of the crucible (12) in the rotating state, so that the heating effect is more significant, and the metal is in a molten state after reaching the melting point. The molten metal enters the cavity between the crucible (2) and the crucible (12) by centrifugal force, flows into the collection bottle (3) along the inner wall of the cavity, and is cooled by the cooling device (4). A waste circuit board metal recycling device based on high-frequency induction heating according to an embodiment of the present invention includes a high-frequency induction ...

Abstract

The invention relates to a waste circuit board metal recovering method and a recovering device based on the high frequency induction heating principle. The recovering method comprises the steps that a crucible is driven to rotate by an electric motor; an induction coil is electrified, the waste circuit board fragment metal in the crucible is heated under the action of electromagnetic induction, the metal under a rotation state clings to the inner wall of the crucible, and the metal shows a molten state after achieving a melting point; the metal under centrifugal force enters a cavity between the crucible and another crucible, then flows into a material collection bottle along the inner wall of the cavity, and finally is cooled by a device.

Description

technical field [0001] The invention relates to a waste circuit board metal recovery device based on the principle of high-frequency induction heating. Background technique [0002] At present, the existing metal recovery methods of waste circuit boards are mainly mechanical physical recovery method and hydrometallurgy method. The product obtained by the mechanical physical recovery method is not the final product, and it needs to be separated and refined again, and the efficiency is low; the cost of hydrometallurgy is high, the amount of chemical agents is large, the leachate and residue are corrosive and toxic, it is difficult to recover all metals, and Serious shortcomings such as polluting the environment and endangering personal health. Contents of the invention [0003] The purpose of the present invention is to provide a metal recycling method for waste circuit boards based on high-frequency induction heating, so as to overcome the above-mentioned deficiencies in t...
