A shaft
kiln is more energy-saving and environment-friendly through utilizing hot
convection and vortex burning in the novel burning method and heating method. The shaft
kiln can form eddying turbulence in a
kiln chamber through utilizing pressurized air flow, and makes the material have even heating. As the movement is mutual, the heating method of rolling material is replaced by the movement of hot air flow around the material, and the material naturally moves to a preheating zone, a heating zone and a cooling zone through utilizing the natural
settling, and the shaft kiln is provided with a
fuel supply device, a burning chamber, a kiln chamber, a fan, an air
pipe,
refractory material and heat-insulating material. The shaft kiln is characterized in that an air inlet is arranged on the side walls of the burning chamber, and is connected with an air inlet
pipe, and the fan is installed on the air inlet
pipe, the burning chamber is connected with the
fuel supply device, the kiln chamber is provided with a heating chamber and a
cooling chamber, the lower portion of the heating chamber is communicated with the
cooling chamber, a feeding inlet is arranged on the upper portion of the heating chamber, and an air outlet is arranged on the upper portion of the heating chamber, a
discharge port is arranged on the lower portion of the
cooling chamber, a kiln chamber air inlet is arranged between the heating chamber and the cooling chamber, and the burning chamber is provided with an air outlet which is communicated with a kiln air inlet.
