Technical Field

[0001] The utility model relates to the field of rotary kiln equipment, in particular to a calcium oxide calcining kiln. Background Art

[0002] Calcium oxide is an inorganic compound with the chemical formula CaO, commonly known as quicklime. It is a white to grayish white block or powder, and its appearance is a white to gray solid. Quicklime needs to be produced through a rotary kiln, which is a common building material equipment, mainly used for calcining cement clinker, metallurgical mines, and magnetic roasting of lean iron ore in steel plants.

[0003] The rotary kiln continuously adds solid materials into the kiln from the higher end of the kiln through a feeder at a given speed, and slowly moves to the other end as the kiln rotates. At the same time, the materials are mixed, heated, and undergo various chemical reactions. The processed materials are continuously discharged from the kiln head and calcium oxide is obtained after cooling. However, due to the high density of solid materials, some materials are prone to segregation in the kiln during the rotation of the rotary kiln, resulting in uneven distribution of calcium oxide in the kiln, which reduces the processing quality of calcium oxide to a certain extent.

[0004] Therefore, it is necessary to provide a new calcium oxide calcining kiln to solve the above-mentioned technical problems. Utility Model Content

[0012] Compared with the related art, the calcium oxide calcining kiln provided by the utility model has the following beneficial effects:
