AI Technical Summary

Technical Problem

The uneven heating of the material layer in the belt roaster, especially the bottom and agglomerated areas, makes it difficult to heat effectively, resulting in high fuel consumption and increased fan energy consumption. There is also a lack of dedicated loosening and heating devices.

Method used

An air supply rod that moves up and down in the material layer is used. Driven by a cantilever wheel and a connecting shaft, combined with a turning tooth and a vent hole, the material layer is loosened and heated evenly. The hot air rod moves up and down in the material layer to achieve air permeability and heating effect.

Benefits of technology

It significantly reduces fuel consumption and fan energy consumption, improves the permeability and heating uniformity of the material layer, and reduces the material-fuel ratio.

Abstract

This invention discloses a heating device for loosening the material layer in a belt roaster. It includes frames on both sides; an upper transmission group and a lower transmission group are correspondingly arranged between the two frames; each transmission group includes: two identical cantilever pulleys respectively arranged on opposite sides of the two frames; a connecting shaft eccentrically arranged between corresponding positions of the two cantilever pulleys; several air supply rods are sleeved on the two connecting shafts; a driving device is used to drive the upper and lower transmission groups on the two frames to rotate synchronously and in the same direction; thereby driving the air supply rods on the connecting shafts to reciprocate up and down. This invention utilizes a driving device to drive the air supply rods to reciprocate up and down, which can loosen the material layer, enhance air permeability, and uniformly heat the material layer.
