Description

High-strength porous brick sintering equipment

Technical Field

The utility model relates to the field of sintering equipment, in particular to high-strength porous brick sintering equipment.

Background

The sintered porous brick is a building material widely applied at present, and particularly in rural areas of China, along with the development of economy and the improvement of the living standard of people, the sintered brick becomes a main building material. In the existing firing process, after green bricks are generally made, natural air drying is carried out, and then energy sources such as coal and the like are used for firing in a firing kiln, so that a large amount of energy sources and air drying time are needed. Moreover, the existing firing kiln has high energy consumption, low production efficiency and serious waste of energy and raw materials.

When the residual moisture in the kiln blank is too high and the initial temperature rising speed of the preheating zone exceeds 25-35 ℃/h, the water in the blank body is quickly vaporized and is not discharged, so that the blank body bursts. The higher the residual moisture, the greater the risk, and in severe cases the kiln roof can smell the cracking sound. Especially, the green bricks just entering the preheating zone after squatting fire are more prone to being fried due to the fact that the temperature is higher, if the preheating zone is heated too rapidly, residual moisture is not too high, water vapor only breaks the surface layer of the brick, and the surface of the brick is provided with fine interweaving cracks like a spider web. The limestone in the raw materials is changed into quicklime after roasting, and the quicklime absorbs moisture in the air to form quicklime after kiln discharge, so that the volume of the quicklime is severely expanded to destroy the brick body. The fuel required for producing baked bricks and tiles in the brickkiln plant mainly depends on coal, and the coal contains carbon, sulfur and other trace elements, so that the produced waste gas mainly contains carbon dioxide, sulfur dioxide, carbon monoxide and other trace elements, and in addition, some dust is discharged into the air.
