Waste heat utilization device of sintering machine

The utility model discloses a sintering machine waste heat utilization device which relates to the technical field of sintering machines and comprises a sintering machine, a trolley is arranged on the inner wall of the sintering machine, a preheating box is fixedly installed on the right side face of the sintering machine, a fixing frame is fixedly installed on the top of the inner wall of the preheating box, and a fan is fixedly installed on the top of the sintering machine. And the output end of the fan is fixedly connected with an air delivery pipe. According to the sintering machine, the fan, the air conveying pipe, the fixing buckle, the flow dividing pipe, the air spraying pipe, the clamping rod, the clamping base and the protective net are matched, hot air in the sintering machine can be pumped out through the air conveying pipe through the fan, and therefore the situation that the hot air is excessively accumulated in the sintering machine, and consequently heat waste is caused can be avoided; materia
