Novel lifting baffling layout structure of rotary furnace

Abstract

The invention discloses a novel lifting baffling layout structure of a rotary furnace. The novel lifting baffling layout structure mainly comprises a rotary furnace tube, a first lifting structure, a second lifting structure, a first baffle plate, a second baffle plate and a guide plate, the first material raising structure and the second material raising structure are F-shaped and are staggered and arranged at intervals; the first baffle plates are two circular baffle plates and are respectively arranged on the first material raising structures at the feeding hole and the discharging hole of the rotary furnace tube, the second baffle plates are arranged between the first material raising structures and the second material raising structures, and the distribution directions of the adjacent second baffle plates are staggered and symmetrical. According to the invention, through the staggered arrangement of the lifting structures and the arrangement of the baffle plates, the motion trail of materials in the rotary furnace tube is wave-shaped baffling rotation, the dispersion degree of the materials on the cross section of the rotary furnace tube is high, the contact area with hot air or process gas is large, the contact time is long, the materials are fully reacted, and the drying effect is good.

Description

technical field [0001] The invention relates to the technical field of related structures of a rotary kiln, in particular to a novel lifting and baffle layout structure of a rotary kiln. Background technique [0002] The rotary furnace is mainly used in the fields of building materials, metallurgy, environmental protection, chemical industry, etc., and the solid materials are processed mechanically, physically or chemically through the rotary furnace. The traditional rotary furnace is generally equipped with a simple L-shaped lifting plate. After the material enters the rotating rotary furnace tube, it is continuously sprinkled through the L-shaped lifting plate area to form a material curtain, fully contacting with hot air or process gas, until The water is fully dried or fully reacted with the process gas, and finally the material enters the subsequent production section through the lower hopper. However, because the general lifting plate is welded on the inner wall of th...

AI Technical Summary

Problems solved by technology

However, because the general lifting plate is welded on the inner wall of the furnace tube and is not easy to replace, and is distributed spirally along the inner wall of the furnace tube, the dispersion of the material on the cross-section of the furnace tube is low, and the contact area with the hot air or process gas is small and the contact time is short. The drying effect of the material is poor or cannot fully react, the work efficiency is low, and the cost is increased
