Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, in particular to a stirring device for lime production. Background Art

[0002] Lime is an air-hardening inorganic cementitious material with calcium oxide as the main component. The original lime production process is to lay limestone and fuel (wood) in layers and ignite and calcine for one week; modern production uses mechanized and semi-mechanized vertical kilns, rotary kilns, boiling furnaces and other equipment, and the calcination time is shortened accordingly. It only takes 2 to 4 hours to produce lime with a rotary kiln, which can increase production efficiency by more than 5 times compared with vertical kiln production. In addition, there are cross-flow, double slope, oil-fired circular vertical kilns and short rotary kilns with preheaters, which have significant energy-saving effects. Fuels have also expanded to coal, coke, heavy oil or liquefied gas.

[0003] In the lime production process, it is usually necessary to stir and mix the lime, and at the same time filter the stirred lime to improve the overall processing quality of the lime. However, the existing stirring device for lime production lacks a filtering device. When filtering the lime, the lime is often stirred first, then taken out, and finally screened using a screening device, which makes the entire lime production process time-consuming and labor-intensive.
