Solid material waste heat utilization stock bin

The invention provides a solid material waste heat utilization stock bin. Solid materials freely fall in the stock bin. The solid material waste heat utilization stock bin is characterized in that at least one opening is formed in the side face close to the bottom of the stock bin; at least one hole opening is formed in the side face of the top of the stock bin or close to the top of the stock bin; at least one metal pipeline used for conveying gas is arranged from the openings to the hole openings in the stock bin, the space between the inner wall of the stock bin and the outer walls of the metal pipelines is a channel for a solid heat-carrying material, each metal pipeline directly penetrates out of the corresponding hole opening, the diameter of each hole opening is larger than the outer diameter of the corresponding pipeline, heat insulation materials are arranged in gaps of the hole openings, at least the outer side and the bottom face of a stock bin body of the stock bin are provided with heat insulation layers, and preferably, the top face is also provided with a heat insulation layer and the stock bin is provided with a top cover capable of being opened. By the adoption of the solid material waste heat utilization stock bin, the traditional technical prejudice is overcome, low-grade and small-scale waste heat can be effectively utilized as well, the energy utilization rate of an enterprise can be increased, and energy conservation and environmental friendliness are promoted.
