Cooling machine high-temp fixed bed anti-stack device for industrial furnace

Abstract

The invention relates to a cooling device for block or particle type material baked in the industrial oven continuously. It includes wall, cooler grate bed, cooling air pipe, cooling air adjusting valve, wind supplying chamber on the movable bed and high temperature grate bed accumulation resisting device, the cooler grate bed is made up of fixed grate bed and movable grate bed, the fixed grate bed is arranged below the material aperture of the industrial oven, the fixed grate bed leans from up down and forma an angle alpha with the movable grate bed, the high temperature grate bed accumulation resisting device is arranged above the fixed grate bed. The advantages of the invention are avoiding the high temperature material from being blocked or pilled on the fixed bed effectively, the material on the fixed bed is more even.

Description

[0001] Involved areas [0002] The invention relates to a cooling device for continuously cooling high-temperature block or granular materials sintered by an industrial kiln (such as a cement rotary kiln), especially a high-temperature fixed-bed anti-accumulation device for a cooler used in an industrial kiln. Background technique [0003] The grate plate or grate bed of a traditional cooler has three functions, namely, supporting the material to be cooled, conveying the material, and distributing the cooling gas into the material bed. This type of cooler is equipped with movable grate plates in the first or second row of the hot end. Because the temperature of the material there is relatively high, the working environment of the grate plates is extremely harsh, and the grate plates are likely to be worn out and burned out. An improved cooler is to replace the original movable bed with an inclined fixed bed in the high temperature section, which can greatly prolong the life of...

AI Technical Summary

Problems solved by technology

However, due to the use of a fixed grate bed, the sintered material (such as clinker) coming out of the high-temperature kiln contains a certain liquid phase, and the temperature is too high, that is, it is easy to form agglomerates, forming so-called "eggs", or piled up into hills In actual production, once an "egg" or "snowman" accident occurs, it is often necessary to stop production to deal with it, which not only causes production loss, but also affects the operating life of the equipment (such as shortening the refractory brick or castable life)
