Abstract

The invention belongs to the technical field of a rotary kiln, in particular to a rotary kiln vertical preheater. The preheater comprises a preheating chamber, material pushing devices, preheating zones, feed tubes, a bin and a feed hopper. The upper and lower ends of the preheating chamber are respectively provided with the bin and the feed hopper; the bottom of the bin is provided with a plurality of feed openings; a plurality of preheating zones are arranged in the preheating chamber along a circumferential direction; each preheating zone communicates with one feed opening of the bin through one feed tube; and the bottom of each preheating zone is provided with one material pushing device mounted on a preheater housing so as to push the material into the feed hopper. According to the preheater, the pressure resistance of the preheater is reduced, thereby reducing the actual power of a motor of a tail exhaust fan, and the energy saving effect is significant.

Description

technical field [0001] The invention belongs to the technical field of a rotary kiln, in particular to a vertical preheater for a rotary kiln. Background technique [0002] Theoretically, calcined metallurgical lime has experienced four eras of technical equipment; successively experienced traditional earth kiln, semi-automatic shaft kiln, fully automatic (PLC controlled) chemical shaft kiln and fully automatic (DCS controlled) rotary kiln. [0003] From the analysis of product quality, the production process of rotary kiln is currently the production process with the most advanced technology, the most stable quality and the best quality indicators in the metallurgical lime industry in the world. Although there is a rotary kiln production process with absolute advantages in equipment, there are still many unreasonable places in actual production. At present, for the vertical preheater, due to the high height of the preheating belt in the preheating chamber (the design mater...
