Description

Technical Field

[0001] The utility model relates to the technical field of lime kilns, in particular to a lime kiln capable of reducing an overburning rate. Background Art

[0002] All natural rocks with calcium carbonate as the main component, such as limestone, chalk, dolomite limestone, etc., can be used to produce lime. When the natural rock with calcium carbonate as the main component is calcined at an appropriate temperature and the decomposed carbon dioxide is removed, the product with calcium oxide as the main component is lime, also known as quicklime. In actual production, in order to speed up the decomposition, the calcination temperature is often increased to 1000-1200℃. Lime kiln is a kind of equipment used to convert limestone into lime. It is mainly composed of kiln body, fuel supply system, limestone supply system and control system. With the development of the industrial system, various lime kilns have appeared on the market.

[0003] In the prior art, when the lime kiln is working, materials will adhere to the inner side of the kiln chamber. If they are not cleaned in time, the overburning rate will be greatly increased when the lime kiln works next time, reducing the quality of lime. The existing lime kiln is inconvenient to clean the inner side of the kiln chamber, and the produced materials will accumulate in the discharge barrel at the bottom of the kiln chamber. If they are not cleaned in time, the materials will be repeatedly heated, causing the materials to be scrapped. Therefore, in view of the above problem, a lime kiln that can reduce the overburning rate is proposed. Utility Model Content
