Description

A kind of hanging refractory liner composite structure for preventing from sinking

Technical field

The utility model is related to a kind of horizontal chamber furnace (oven) refractory liner structures, in particular to a kind of to prevent the hanging resistance to of sinking Fiery lining composite structure.

Background technology

According to the handling characteristics of industrial furnace, refractory material is not supported completely in some cases, mainly by refractory brick It is hanging combination mutually support, such as the top of horizontal pipe, stove, the vault part of gasification furnace, arcuate part of Industrial Stoves etc.. The support of these industrial furnace refractory liners combines arching mainly by refractory liner, generates corresponding support force, room temperature may be implemented Structural stability under cold conditions.But during stove hot operation or during stove has carried out heating cooling, this The stable structure of kind can become unstable.General involved refractory brick is all there are six face, one of them is working face, one For backing face, four additional is that refractory liner contacts with each other face.Conventional refractory brick is that straight shaped brick or two contact with each other face On have a structures such as snap fastener or step or four contact with each other on face the structures such as snap fastener or step.

When high temperature, refractory material will produce certain creep, lean on the structure of arch support, can sink in the effect of gravity The phenomenon that, when sinkage is serious, it may appear that top refractory liner caves in；In addition for intermittent industrial furnace, in stove When heating, material mutually expands extruding, when stove cools down, the mutual contraction stretching of material；The extruding and stretching of material It is that may result in lining material position in this way without directionality and opposite offset has occurred, the form of expression is cracking, the fissure of displacement, platform Rank etc..All there is the above problem in existing composite structure, influence the stability of structure, it may appear that the phenomenon that the overtemperature of top, jeopardize Industrial furnace it is safe to use.

Utility model content

In order to solve the above technical problems, the purpose of this utility model is to propose a kind of hanging refractory liner group for preventing from sinking Close structure.

The utility model is to complete above-mentioned purpose to adopt the following technical scheme that：

A kind of hanging refractory liner composite structure for preventing from sinking, the hanging refractory liner composite structure have multiple The annulus being composed of radial brick；Tenon with outwardly convex on one side end face of every block of radial brick, tenon tool There is the horizontal projection being arranged along radial brick length direction；The horizontal projection is parallel to the annular working face setting of radial brick； The vertical protrusion that the tenon is also arranged with twice perpendicular to annular working face；Vertical protrusion described in twice and the water Plano-convex rises and collectively forms crisscross tenon structure；Have and phase in other annulus on another side end face of every block of radial brick Tenon structure on adjacent two blocks of radial bricks kisses the mortise matched.

The utility model proposes it is a kind of prevent sink hanging refractory liner composite structure, from the refractory brick of overhanging portion Brick design and combination on optimize, realize this ring one piece of brick can completely mortise and tenon to a upper ring two pieces of bricks On, the respective half of two pieces of bricks is lockked by the tenon structure of cross in length and breadth, realizes that a brick locks the function of two bricks；It is entire outstanding in this way The structure of empty part interlocks against, and forms an organic whole.It can reduce between brick and brick at high temperature or temperature becomes The possibility that relative displacement occurs when dynamic, maintains the overall stability of structure；To ensure that the long week of this hanging structure Phase stable operation.

Fig. 2 is the side view of Fig. 1.

In figure：1, radial brick, 2, horizontal projection, 3, vertical protrusion, 4, mortise.

Specific implementation mode

The utility model is illustrated with reference to the drawings and specific embodiments：

As shown in Figure 1 and Figure 2, a kind of hanging refractory liner composite structure for preventing from sinking, the hanging refractory liner group Closing structure has multiple annulus being composed of radial brick；There is outwardly convex on one side end face of every block of radial brick 1 Tenon, the tenon has the horizontal projection 2 that is arranged along radial brick length direction；The horizontal projection 2 is parallel to radial brick Annular working face setting；The tenon also has vertical raised 3 that twice are arranged perpendicular to annular working face；Described in twice Vertical protrusion 3 collectively forms crisscross tenon structure with the horizontal projection 2；Another side end face of every block of radial brick The upper tenon structure with other annulus on adjacent two blocks of radial bricks kisses the mortise 4 matched.

When design list brick brick, according to the technological requirement of the internal diameter of transversal tubular structure, the radial brick for being suitble to size is designed, The vertical tenon structure of one cross two of setting in the forming surface of radial brick, because tenon structure is there are in forming surface, and the surrounding of brick For shiny surface, the molding difficulty of brick body can be reduced, ensures the compactness extent of green brick forming.Adobe after molding is according to adobe material The requirement of matter carries out corresponding temperature firing or processing, refractory product is made.

It in building process, is required according to chamber size in stove, makes the corresponding mould of overhanging portion.When building by laying bricks or stones, in mould It is upper pre-assembled, gradually built by laying bricks or stones according to every ring, when building the second ring brick by laying bricks or stones, one piece of brick of this ring can mortise and tenon completely to upper one On two pieces of bricks of ring, the respective half of two pieces of bricks is lockked by the tenon structure of cross in length and breadth.Realize that a brick locks the function of two bricks, The structure of overhanging portion entire in this way interlocks against, and forms an entirety.

After removing mould, the arch self-locking of tubular structure can prevent fire resisting per the tenon structure self-locking between ring brick For brick because structure slides, sinkage caused by the reasons such as cracking ensure that the stability of hanging refractory liner composite structure.
