Scrap iron separating device suitable for being used after railway steel rail polishing and scrap iron cleaning

The invention belongs to the technical field of scrap iron processing, and particularly relates to a scrap iron separating device suitable for railway steel rail polishing and scrap iron cleaning. Comprising an electromagnet conveying belt, and a plurality of strip-shaped electromagnets are arranged on the electromagnet conveying belt; a plurality of electromagnet power supply grooves are formed in the corresponding positions of the two sides of the electromagnet conveying belt. The electromagnet power supply groove is composed of a power supply groove part and a non-power-supply groove part, and the power supply groove part is provided with an electric brush. An impurity conveying belt is arranged below the right side of the electromagnet conveying belt; the right strip-shaped electromagnet is positioned in the power supply groove part; a scrap iron conveying belt is arranged on the lower left portion of the electromagnet conveying belt. The strip-shaped electromagnets on the left side are located in the non
