X-ray machine foreign matter detection device

The invention relates to an X-ray machine foreign matter detection device, and the device is mainly used in the field of petroleum coke calcining in the carbon industry. Two ends of a conveying belt are respectively provided with a belt speed measurement apparatus, and an X-ray machine is disposed above the central part of the conveying belt. The ends of the conveying belt are opposite to material inlets of an electric T-joint material distribution device. Two material inlets of the electric T-joint material distribution device are respectively opposite to material conveying equipment and an unqualified product recovery apparatus. Control signals of all equipment enter into a controller, and all equipment is automatically controlled by the controller. According to the invention, the device is added to a flow after the calcining of petroleum coke. Through the X-ray machine, the belt speed measurement apparatus, the controller and the electric T-joint material distribution device, the device can automatically carry out the foreign matter detection of a product after the calcining of petroleum coke, automatically carries out the recovery processing of the product comprising a foreign matter, and improves the quality of a calcining product of petroleum coke.
