Description

Technical Field

[0001] The utility model relates to a lime kiln ash discharging mechanism, in particular to a novel double-chamber lime kiln ash discharging mechanism. Background Art

[0002] The ash discharging mechanism of the existing double-chamber lime kiln is a cone-shaped part welded to the flange of the kiln base. The cone-shaped part of the ash discharging mechanism of this structure is welded to the flange of the bottom of the kiln body. During the production operation, the kiln body is stationary. The frequent push-pull drive of the ash discharging assembly of the support plate under the cone can easily cause cracking of the weld. Since the refractory bricks are built on the flange of the bottom plate of the kiln shell, the flange of the bottom plate of the kiln shell is a metal structure and cannot be effectively combined with the refractory material. Due to the different thermal expansion coefficients, large cracks are easily generated after heating during production. The kiln body is under positive pressure, which causes the hot air in the kiln to burst out of the refractory brick insulation layer and directly bake the kiln shell. The hot air directly bakes the kiln shell for a long time, which can easily cause the kiln shell to deform and reduce its strength, resulting in production accidents. In addition, the bursting of hot air causes heat loss in the kiln body, which is not conducive to the burning of high-activity lime. Utility Model Content
