Feeding system for rotating-drum method slag processing apparatus

The invention relates to an environmentally-friendly smelting slag processing apparatus, and especially relates to a feeding system for a slag processing apparatus. The feeding system for the rotating-drum method slag processing apparatus comprises a crushed slag hopper, a hopper support stand, a hopper lifting mechanism, a feeding cylinder, a cylinder cover operation dolly, a cylinder support device, a cold steel removing device and a cold steel transferring dolly; a material outlet of the feeding cylinder is connected with a material inlet of the slag processing apparatus through a flange, the hopper support stand is arranged over the material inlet of the feeding cylinder, and the crushed slag hopper is installed on the hopper support stand through the hopper lifting mechanism; the cylinder cover operation dolly is arranged at a side portion of an operation end of the feeding cylinder; the cylinder support device is arranged at the bottom of the feeding cylinder; and the cold steel removing device is arranged at the side portion of the operation end of the feeding cylinder, and the cold steel transferring dolly is arranged below the feeding cylinder. The feeding system guarantees the effective running of the pot bottom slag processing apparatus, and provides an effective means for the automatic control of the feeding system for the slag processing apparatus.
