Arched bearing platform of fluidized roaster and pouring method of arched bearing platform

Abstract

The invention discloses an arched bearing platform of a fluidized roaster and a pouring method of the arched bearing platform. The arched bearing platform comprises a bearing platform main body and a supporting table; the bearing platform main body is fastened with the supporting table through an L-shaped fastening surface; the bearing platform main body is formed through layered pouring from a plurality of layers of different castables, and the various layers are spaced by hydrophobic fiber plates; air holes formed in the bearing platform main body are connected by use of wear-resistant and high temperature-resistant high aluminum ceramic tubes at the junctions of different material layers; as the hydrophobic fiber plates are added, a cooperation structure of the bearing platform main body and the supporting table is improved and steel fibers different in content are added to the castables, the arched bearing platform is capable of reliably bearing the weight of materials in a roasting chamber and a high-frequency vibration load during fluidized roasting, and also capable of effectively preventing the materials from dropping into a combustion chamber at the bottom from the roasting chamber.

Description

technical field [0001] The invention belongs to the field of fluidized roasting furnaces, and in particular relates to an arched load-bearing platform of a fluidized roasting furnace and a pouring method thereof. Background technique [0002] At present, most of the fluidized roasting furnaces used in my country use high-pressure air to fluidize the materials at the bottom of the furnace, and then directly heat the materials by burning natural gas and diesel in the furnace. But for some materials (such as foundry old sand), when the flame is in direct contact with the material, a small amount of the material will reduce the quality of the roasted material due to excessive local temperature. [0003] In the prior art, some roasters have begun to adopt the method of setting the combustion chamber separately from the roasting chamber, that is, the combustion chamber is directly arranged at the lower part of the roasting chamber. In this way, high-pressure air, natural gas or d...
