Abstract

The utility model discloses a structure of liner for limestone kiln, consisting of a furnace body, a bauxite brick layer which is installed on the inner side of the furnace body and a light high-alumina and heat insulating brick layer which is installed on the outside closing to the bauxite brick layer. The bottom of the furnace body is provided with a substrate which is wholly cast. The upper part of the furnace lining of the furnace body is provided with a beam ringing layer which is cast. The substrate is provided with a thermal insulating gap. The substrate and the beam ringing layer are provided with a steel bar. The utility model is provided with some advantages of able to reduce the usage of anomalous brick, decreasing abrasion of the inner liner and improving service life of the furnace lining.

Description

The configuration structure of limestone kiln liner

Technical field:

The utility model relates to a kind of configuration structure of limestone kiln liner.

Background technology:

Current, traditional limestone kiln liner all is to be built into refractory brick, for adapting to the shape of stove, will use a large amount of special form bricks when building furnace lining by laying bricks or stones, and its amount of building by laying bricks or stones is big, and causes very big waste.When producing, the furnace bottom especially refractory wear of its tapering part is serious, and stove top is because the impact of being expected, its refractory brick comes off easily too early, makes that the service life of furnace lining is shorter.

Summary of the invention:

The purpose of this utility model is: provide a kind of use that can reduce special form brick, and the wearing and tearing that reduce liner are with the configuration structure of the limestone kiln liner that improves furnace lining service life, to overcome above-mentioned the deficiencies in the prior art.

The utility model is to constitute like this: it comprises the light high-alumina insulating brick layer (2) that the outside of body of heater (7) and high aluminium brick layer (1) that is provided with in the inboard of body of heater (7) and adjacent high aluminium brick layer (1) is provided with, be provided with integrated poured substrate (3) in the bottom of body of heater (7), be provided with the ring beam layer (4) of cast on the furnace lining top of body of heater (7); Insulation seam (5) is arranged in substrate (3); In substrate (3) and ring beam layer (4), reinforcing bar (6) is arranged.

The utility model is compared with prior art: to water material feeding integrated poured because substrate adopts, and the ring beam layer of cast is arranged on the top of furnace lining, makes that the use to special form brick significantly reduces, and make that the globality of furnace lining is better, reduced the wearing and tearing of liner.The insulation seam

Be provided with and can play heat insulation effect, in pouring layer, use reinforcing bar then can effectively prevent liner distortion, the service life of improving furnace lining.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a furnace bottom beam arrangement of reinforcement.

The specific embodiment:

Embodiment of the present utility model: high aluminium brick layer (1) and the light high-alumina insulating brick layer (2) of using high-alumina brick and the brick brickwork body of light high-alumina insulating (7) earlier, strengthen castable refractory cast substrate (3) and ring beam layer (4) and in substrate (3), stay an insulation seam (5) with the drill rod dimension then, in insulation seam (5), insert the alumina silicate fiber plate, heat insulation to play, as to prevent material temperature distortion effect, employed drill rod dimension strengthens the refractoriness fine (＞1790 ℃) of castable refractory, the line rate of change is little (1500 ℃, 3h＜0.2%=, the intensity height (〉=60MPa); When stove is worked, for liner is not deformed, add straight when cast substrate (3) and ring beam layer (4) therein through being 12 and 6 millimeters stainless steel rebar (6).
