Description

Technical Field

[0001] This invention relates to the field of metal detectors, and more particularly to a metal detector with a rejection function. Background Technology

[0002] Metal detectors are mainly used for detecting foreign metal objects in industries such as snacks, chemical products, clothing, footwear, marine aquatic products, fisheries, dried and fresh aquatic products, pasta, frozen foods, dried and fresh fruits and vegetables, sugar, tea, and pharmaceuticals. They detect various metal impurities such as iron and lead that are mixed in or have fallen into the raw materials or products.

[0003] Metal detectors use the principle of electromagnetic induction to detect metals. All metals, including ferrous and non-ferrous metals, have high detection sensitivity. When ferromagnetic metals enter the detection area, they affect the distribution of magnetic field lines, thus affecting the magnetic flux within a fixed range. When non-ferromagnetic metals enter the detection area, they generate eddy currents, which also alter the magnetic field distribution within the detection area.

[0004] However, existing metal detectors have relatively simple structures and generally do not have the function of removing metal, which affects their applicability. Summary of the Invention

The discharge pipe has a port corresponding to the discharge pipe. An electromagnet is fixedly connected to the inner wall of the port.

[0011] The output terminals of the electromagnetic induction module, signal receiver, and power supply are all connected to the input terminal of the controller, and the output terminal of the controller is connected to the input terminals of the electromagnet and the memory, respectively.
