Energy-saving kiln for producing high-aluminum poly light ball bricks

The energy-saving kiln comprises a kiln body and a plate trailer, the upper surface of the plate trailer is rotationally connected with a lower base plate through a rotating seat, an upper base plate parallel to the lower base plate is detachably connected to the upper portion of the lower base plate, a plurality of circulating holes are formed in the upper base plate in a penetrating mode, and the circulating holes are communicated with the lower base plate. A screw shaft is embedded in the plate trailer in a lifting mode, and the top end of the screw shaft is fixedly connected with a top block. According to the utility model, through the design of the lower base plate, the upper base plate, the circulation hole and the upper insertion cylinder, a larger space gap can be formed below a brick pile, so that air flow in a kiln can circulate upwards from the lower part of the brick pile, the air flow can circulate more smoothly, the firing efficiency is improved, and the fuel consumption can be reduced; accordin
