The invention discloses a heat recycling device for a refractory brick calcining kiln cooling chamber. The heat recycling device comprises the cooling chamber, an auxiliary kiln and a feeding chamber. A dense gas collecting pipe is arranged on the inner side of the top of the cooling chamber. A plurality of air inlet holes are formed in the top of the gas collecting pipe. An air outlet of the gas collecting pipe is connected with a draught fan through an output pipeline. An input pipeline is connected to the other side of the draught fan and connected with an auxiliary kiln input pipeline and a feeding chamber input pipeline through a three-way valve. The auxiliary kiln input pipeline is connected with the auxiliary kiln. An auxiliary kiln input valve is connected to the auxiliary kiln input pipeline in series. The feeding chamber input pipeline is connected with the feeding chamber. A feeding chamber input valve is connected to the feeding chamber input pipeline in series. According to the heat recycling device for the refractory brick calcining kiln cooling chamber, heat of the cooling chamber is recycled and transferred into the feeding chamber and the auxiliary kiln, so that effective utilization of the heat of the cooling chamber is achieved, the heat is reused in production, and energy consumption of the refractory brick auxiliary kiln and the feeding chamber is greatly reduced.
