Abstract

The invention relates to an atmosphere-adjustable double-temperature-control composite ceramsite sintering rotary furnace and a working method thereof. The atmosphere-adjustable double-temperature-control composite ceramsite sintering rotary furnace comprises a tubular preheating furnace, a speed reducer, supports, a sectioning partition and a tubular sintering furnace, heaters are arranged outside a preheating furnace tube and a sintering furnace tube respectively, thermocouples are arranged in the preheating furnace tube and the sintering furnace tube respectively and are connected with automatic temperature controllers, the speed reducer drives the preheating furnace and the sintering furnace to rotate through linkage chains, and an atmosphere-adjustable ceramsite collector is further arranged outside the sintering furnace. The atmosphere-adjustable double-temperature-control composite ceramsite sintering rotary furnace integrates preheating and sintering and is capable of rotating at a uniform speed, adjustable in preheating and sintering atmosphere, reasonable in allocation and capable of achieving continuous production of ceramsite sintering.

Description

technical field [0001] The invention relates to an adjustable-atmosphere double-temperature-control composite ceramsite sintering rotary furnace and a working method thereof, belonging to the technical field of ceramsite sintering. technical background [0002] In recent years, with the rapid development of social economy and the continuous improvement of people's living standards, the types and quantities of solid waste have increased sharply, and solid waste pollution incidents have occurred frequently, which has seriously affected human health and environmental safety. How to deal with the solid waste generated in the process of industrial production and urbanization has attracted more and more attention. Solid waste mainly includes domestic garbage and industrial solid waste, which are a misplaced resource. Realizing waste recycling, reducing industrial consumption, and eliminating the hazards caused by solid waste are the focus of research in countries all over the wor...
