Abstract

The invention relates to nonferrous metal classification technology, in particular to a nonferrous metal classification device and method based on an eddy current sensor. The invention solves the problem of low classification accuracy of the existing nonferrous metal classification technology. A non-ferrous metal classification device based on an eddy current sensor, including a belt conveyor, an electric lifting column, an eddy current sensor, an analog switch chip, a power amplifier, a signal generator, a signal conditioner, and a host computer; wherein, the belt conveyor Fixed horizontally on the ground; the electric lifting column is vertically fixed on the ground beside the belt conveyor; the eddy current sensor includes a shell, a transmitting coil, and a receiving coil; the shell is fixed on the side of the cylinder of the electric lifting column, and the shell The body is located directly above the conveyor belt of the belt conveyor; the transmitting coil and the receiving coil are fixed in the housing, and the axes of the transmitting coil and the receiving coil are perpendicular to the upper surface of the belt conveyor. The invention is applicable to the classification of non-ferrous metals.

Description

technical field [0001] The invention relates to a non-ferrous metal classification technology, in particular to a non-ferrous metal classification device and method based on an eddy current sensor. Background technique [0002] Non-ferrous metals are widely used in industry and are important materials and key strategic materials for the development of the national economy. In addition to ore smelting to obtain non-ferrous metals, the classification, recovery and regeneration of non-ferrous metals is an important source of raw materials. At the same time, the classification and recovery of non-ferrous metals is an important part of the earth resource recycling industry. It has an important position in the sustainable development strategy of the world and my country, and is an important challenge faced by the modern economic transformation. [0003] At present, the classification of non-ferrous metals is generally carried out by eddy current separators. However, in practical...
