High-temperature atmosphere rotary kiln with lining pipe of hexagonal structure

Abstract

The invention provides a high-temperature atmosphere rotary furnace with a hexagonal inner lining tube. Due to the rotation of the furnace tube and the hexagonal inner lining tube of the furnace tube, it can ensure that the material in the furnace tube is heated evenly, so that the entire material The work efficiency of heating and conveying is low and high, which improves the production efficiency of the production line. It includes a bottom plate, a heating shell is arranged on the bottom plate, and the two ends of the heating shell are respectively provided with a hopper and a hopper. The inside of the heating shell is provided with a furnace tube. There are multiple sets of thermocouples. The cross-section of the lining tube of the furnace tube is a hexagonal structure. The inlet and outlet ends of the furnace tube are respectively exposed at the two ends of the heating shell. The two ends of the casing are respectively provided with circular rings at the connection positions, and the circular rings are covered with a rotating bearing structure, and the entrance and exit ends of the furnace tube exposed to the heating shell are respectively fastened with rolling ring structures.

Description

technical field [0001] The invention relates to the technical field of material conveying heating, in particular to a high-temperature atmosphere rotary furnace with a hexagonal inner lining pipe. Background technique [0002] The existing powder is heated and transported through a pusher kiln or a roller kiln, and the material is mixed with the heat emitted by the hot air burned in the kiln for heating. During the conveying process, the material is not heated uniformly, and The heat loss is relatively large, so that the heating of the material requires a huge amount of energy, and because the material is heated unevenly, the heating time of the material in the kiln chamber is long, which makes the work efficiency of the entire material heating and transportation low, delays the entire production process, and makes the production line The production efficiency is low; in addition, the entire heating furnace body of the existing rotary kiln rotates, so that the load of the dr...
