Tank bottom slag feeding system of roller type slag treatment device

The invention relates to a tank bottom slag feeding system of a roller type slag treatment device. The tank bottom slag feeding system mainly comprises a feed hopper, a hopper supporting rack, a feeding barrel, a barrel supporting device, a cold steel removing device and a cold steel hopper; the feeding barrel is connected with slag treatment equipment through a flange; the feed hopper is mounted on the hopper supporting rack, and the lower outlet of the feed hopper is extended into the feeding barrel; the barrel supporting device is mounted below the feeding barrel; the cold-steel removing device is mounted in front of the end part of the feeding barrel, and a telescopic arm of the cold steel removing device is extended into the slag treatment device by virtue of a feed port of the feeding barrel to remove cold steel; the cold steel hopper is arranged in the anterior inferior part of the feeding barrel; the cold steel removed by the cold steel removing device is positioned into the cold steel hopper. According to the tank bottom slag feeding system of the roller type slag treatment device, the simple, reliable and low-cost stable operation is realized; a simple, convenient and stable effective manner is provided for realizing the one-time feeding of the complete tank bottom slag, the removal of cold steel, and the automatic control of a feeding system of slag treatment device.
