Refractory bricks for rotary kiln

Abstract

The invention belongs to the field of refractory bricks, and in particular relates to refractory bricks for a rotary kiln. Each refractory brick comprises a glass fiber heat insulation layer, fixing limiting rings, a kiln cavity, a rock wool upper cover, a rock wool lower cover, embedding grooves, embedding limiting blocks, refractory clamping bricks, a filling groove cavity, glass fiber filling blocks, embedding clamping grooves, a first refractory slurry layer, mounting holes, a second refractory slurry layer and mounting strips. According to the refractory bricks, the structure is reasonable; after being used, the refractory bricks perform fire resisting through the self-refractory property, and meanwhile, through the cooperation of the glass fiber filling blocks, the rock wool round covers and the glass fiber heat insulation layer, heat insulating can be effectively carried out, so that the integral heat insulation effect of the rotary kiln is improved, and the heat loss is reduced; when the refractory clamping bricks are laid to form the kiln cavity, the refractory clamping bricks and the embedding clamping grooves are clamped, so that suspending is carried out, and limiting is realized; and mounting and stacking are simple, and when laying is carried out, the refractory clamping bricks are not needed to be manually supported, so that the convenience is provided for construction.

Description

technical field [0001] The invention belongs to the field of refractory bricks, in particular to a refractory brick for a rotary kiln. Background technique [0002] Refractory bricks are referred to as refractory bricks; refractory materials fired with refractory clay or other refractory materials; light yellow or brownish; mainly used for building smelting furnaces, capable of high temperatures from 1580°C to 1770°C; rotary kilns refer to rotary calcining kilns, It belongs to the category of building materials and equipment; rotary kilns can be divided into cement kilns, metallurgical and chemical kilns and lime kilns according to different materials to be processed. Generally, refractory materials are laid and stacked inside to achieve refractory. [0003] Existing refractory bricks generally have a rectangular block structure. When stacking, they are generally only glued together by refractory mud to achieve connection. After stacking, refractory bricks may easily fall of...

Problems solved by technology

[0003] Existing refractory bricks generally have a rectangular block structure. When stacking, they are generally only glued together by refractory mud to achieve connection. After stacking, refractory bricks may easily fall off, and generally need support structures to support and improve After laying, refractory bricks are usually only fixed by refractory mud, and in some remote areas, when the temperature difference between day and night is large, they are prone to fall
