[0002] Calcium oxide, commonly known as quicklime or lime, is a common inorganic compound. The term "lime" is widely used to indicate calcium-containing inorganic materials. Calcium oxide is usually obtained from limestone or seashells. Heating the material containing calcium carbonate to 500-600℃ causes it to decompose into calcium oxide and carbon dioxide. Lime kiln (commonly known as lime kiln) is a device for producing lime, which is widely used in construction, metallurgy, chemical industry and other fields.

[0003] The existing kiln cannot control the addition amount of raw materials according to the actual situation during use, resulting in the phenomenon of excessive or insufficient injection amount of raw materials, which is not conducive to the production and processing of quicklime. Referring to the prior art CN217651125U, when the required amount of lime is large, the air cylinder drives the rack to move, and when the rack moves, the two gears rotate, so that the two connecting rods rotate, and when the two connecting rods rotate, the first threaded rod and the second threaded rod threaded in the moving hole move towards each other, so that the two baffle plates move towards each other, thereby expanding the space of the two feeding grooves.

[0004] The above-mentioned prior art adjusts the feeding groove in a complex way, which needs to cooperate with gears, connecting rods, threaded rods, baffles and other components to realize adjustment. In order to improve the feeding speed, the number of feeding grooves is at least 2 or more. However, the prior art cannot adjust the space size of 2 or more feeding grooves, so the applicability is poor. UTILITY MODEL CONTENTS
