The invention discloses low-energy-consumption industrial microwave sintering equipment and belongs to the field of microwave sintering. The equipment comprises a bottom plate, the upper surface of the bottom plate is fixedly connected with a sintering furnace base, a sintering furnace is fixedly connected with the top of the sintering furnace base, a driving box is fixedly connected with the upper surface of the bottom plate, a driving motor is fixedly connected with the inner bottom wall of the driving box, the output end of the driving motor is sleeved with a first gear, one side of the first gear is engaged with a second gear, a rotating shaft is inserted into the inner wall of the second gear, a rotating column is fixedly connected to the top of the rotating shaft, and the outer wallof the rotating column is sleeved with a fixed cylinder. Through the arrangement of the driving motor, the first gear, the second gear, the rotating shaft, the rotating column, a supporting arm, an extensible air cylinder, a limiting barrel, an electric push rod and a clamping plate, the design is high in automation degree and operation is easy; the trouble of manually taking out a crucible is avoided, workers are prevented from making direct contact with the crucible, and the workers are prevented from being scalded; and therefore, the effects that the device is convenient in material takingand high in safety are achieved.
