Description

Technical Field

[0001] The utility model relates to the field of roasting furnace equipment, in particular to a rotary roasting furnace for improving roasting efficiency. Background Art

[0002] The rotary kiln is a thermal equipment for calcining, roasting or drying granular and powdered materials. The rotary kiln body is a long steel cylinder with a heating and heat preservation furnace on the outside of the cylinder. The furnace body is supported on several pairs of supporting wheels and has a certain inclination. The furnace body is driven by the motor to rotate slowly through gears. The material is added from the higher end of the cylinder and discharged from the lower end of the cylinder; the flue gas can enter from the lower end of the cylinder and be discharged from the higher end. It is widely used in the chemical industry for drying and roasting materials, but during use, the materials inside the rotary kiln are often piled together. During the turning process, the materials slide along the cylinder wall, so that the materials cannot be fully dispersed, thereby reducing the combustion efficiency. In addition, the furnace body cannot purify the flue gas generated by roasting. The direct discharge of the flue gas generated by roasting will cause air pollution and endanger people's health.
