The invention provides an anthracite lime shaft kiln and a transformation method thereof. The anthracite lime shaft kiln comprises a preheating zone, a calcining zone, a cooling zone and a dischargingzone which are distributed in the lime shaft kiln from top to bottom, wherein a ratio of the diameter of the circumference of the bottom of the lime shaft kiln to height is 4.5-5; a feeding port is formed in the upper end of the preheating zone; a transition stock bin is arranged on the lower side of the feeding port; a conveying mechanism is arranged at a discharging opening of the transition stock bin; a material distributing mechanism is installed on the lower side of the conveying mechanism; a breathable partition plate is laid at the bottom of the preheating zone; heat-proof partition plates are laid at the bottoms of the calcining zone, the cooling zone and the discharging zone; a material guiding mechanism is arranged in the middles of the heat-proof partition plates in a penetrating mode; a fan is mounted at the gas inlet of the calcining zone; a layer of fire grate is laid at the bottom of the discharging belt, and a scraper discharging mechanism is arranged below the discharging zone, so the problem of poor lime calcining effect caused by poor structure of a conventional lime shaft kiln is solved, and the lime shaft kiln is reasonable in structure, high in purity of produced lime, uniform in heating and high in heat utilization rate.
本发明提供一种无烟煤石灰竖窑及其改造工法,包括从上至下分布在石灰竖窑内的预热带、煅烧带冷却带和卸料带，石灰竖窑底部圆周直径与高度比为4.5‑5，预热带上端开设有进料口，进料口的下侧设置有过渡料仓，过渡料仓的出料口处设置有传输机构，传输机构下侧安装有布料机构，预热带底部铺设有透气隔板，煅烧带、冷却带和卸料带底部均铺设有防热隔板，防热隔板中间贯穿设置有导料机构，煅烧带进气口安装有风机，卸料带的底部铺设有一层炉篦，卸料带下方设置有刮板卸料机构，解决了以往的石灰竖窑结构不佳，导致石灰煅烧效果欠佳的问题，本发明结构合理，产出的石灰纯度高，受热均匀，热量利用率高。
