Abstract

The embodiment of the utility model discloses an induction treatment device of metal filings, which comprises a magnetic core plug and a testing resistor, wherein two poles of the magnetic core plug are oppositely arranged; and the testing resistor is connected with the magnetic core plug with the two opposite poles in parallel, and the magnetic core plug can ablate the normal metal filings adsorbed between the two poles of the magnetic core plug by releasing energy. In order to perfect the scheme, the device comprises an alarm unit, wherein the alarm unit is connected on a main circuit of a parallel circuit formed by the testing resistor and the magnetic core plug with the two opposite poles in series. When the filings are adsorbed between the two poles of the magnetic core plug for conduction, due to the principle that the total resistance becomes small after parallel connection of the resistor, after electrification ablation treatment is started by an energy storage element connected with the device in a way of releasing the energy, if the filings caused by abnormal abrasion can not be fully molten, a photoelectric alarm is emitted, otherwise, the alarm is canceled, the false alarm caused by the filings due to normal abrasion can be further eliminated and the accuracy of the alarm is further improved.
