Abstract

The application relates to a rotary kiln for efficient production of metallurgical lime, which includes a kiln head cover, a kiln body, a driving assembly, a feeding hopper, a transmission assembly and a speed regulating box. One end of the kiln body is arranged on the kiln hood, a large gear is arranged on the outer surface of the kiln body, and the driving assembly is connected with the large gear. The feed hopper is arranged on one side of the kiln hood and communicates with the inner chamber of the kiln body, and a valve plate is arranged under the inner chamber of the feed hopper. The transmission assembly includes a first gear and a transmission shaft, the first gear meshes with the large gear, one end of the transmission shaft is connected to the first gear, the other end is connected to the input end of the speed control box, and the output end of the speed control box is connected to the valve plate , when the large gear drives the transmission shaft to rotate through the first gear, the transmission shaft controls the speed of the material entering the inner chamber through the speed control box to control the speed of the valve plate, so that the material can be adjusted only by adjusting the transmission ratio / gear position of the speed control box The speed of entering the kiln chamber can ensure the orderliness of metallurgical lime production and improve the effect of lime forging.

Description

technical field [0001] The present application relates to the technical field of rotary kilns, in particular to a rotary kiln for efficient production of metallurgical lime. Background technique [0002] Metallurgical lime can be divided into ordinary metallurgical lime and magnesia metallurgical lime according to different materials. Ordinary metallurgical lime is fired with limestone, has high calcium oxide content and does not contain magnesium oxide. Magnesia metallurgical lime is fired from magnesia limestone, containing about 5% magnesia by mass fraction and low calcium oxide content. [0003] Existing metallurgical lime is produced in a rotary kiln. The raw material is mainly fed into the feed hopper through a screw feeder, and then the raw material is fed into the kiln head through the feed hopper, thereby entering the rotary kiln for calcination. However, the applicant found that the feeding hopper of the existing rotary kiln itself cannot adjust the feeding speed,...
