Description

Technical Field

[0001] The invention belongs to the technical field of refractory bricks, and in particular relates to a refractory brick with a reinforced structure. Background Art

[0002] Refractory bricks are a kind of refractory material with a certain shape and size. They are widely used in the lining of kilns and can play a good role in heat preservation and heat insulation. The refractory bricks used in existing kilns will become loose at the stacking place due to the change of temperature in the furnace after being stacked for a period of time, which will expand the opening of the stacking place, causing the heat in the furnace to be lost from the stacking place, reducing the firing quality of the product; in severe cases, the bricks will fall off, causing the kiln to collapse.

[0003] At the same time, the refractory bricks commonly used in the prior art are solid bricks, which consume a large amount of materials, cannot effectively keep warm, are flammable in the event of a fire, cannot achieve a good thermal insulation effect, have very poor safety, and bring serious safety hazards to people's lives. Summary of the invention

[0004] The purpose of the present invention is to provide a refractory brick with a reinforced structure, which solves the problems of low strength, easy loosening and poor thermal insulation effect of existing refractory bricks through the design of an inner lining frame, a heat storage cavity, a limit strip and a positioning hole.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention provides a refractory brick with a reinforced structure, comprising a refractory brick substrate; two adjacent surfaces of the refractory brick substrate are fixedly connected with protrusions; one surface of the two protrusions is symmetrically provided with two limit strips; the other two adjacent surfaces of the refractory brick substrate are provided with grooves matching with the protrusions; one surface of the two grooves is symmetrically provided with two positioning holes matching with the limit strips; a sealing groove is provided on the top surface of the refractory brick substrate; a sealing block matching with the sealing groove is fixedly connected to the bottom surface of the refractory brick substrate; a plurality of connecting holes are also provided on one surface of the refractory brick substrate; lining frames are clamped on the inner walls of the plurality of connecting holes; four mutually interconnected heat storage cavities are provided inside the lining frame; a heat preservation cavity is also provided on one surface of the lining frame; two groups of heat inlet holes are provided on one surface of the lining frame; a sealing plate matching with the four heat storage cavities and the heat preservation cavity is also fixedly connected to the bottom surface of the refractory brick substrate.

[0007] Furthermore, the interior of the heat preservation cavity is fixedly filled with hard polyurethane foam plastic; and the heat preservation cavity is a "cross"-shaped structure.

[0008] Furthermore, the sealing groove is an annular groove; the sealing plate is located inside the sealing groove; and a refractory adhesive layer is fixedly provided on a surface of the lining skeleton close to the refractory brick substrate.

[0009] Furthermore, a waterproof membrane is fixedly provided on the protrusion and the inner wall of the groove; the refractory brick substrate is an annular structure; and a fireproof coating is coated on the peripheral side of the refractory brick substrate.

[0010] Furthermore, the heat inlet hole is a countersunk hole; and the heat storage cavity is a square cavity.

[0011] The present invention has the following beneficial effects:

[0012] 1. The present invention changes the traditional solid bricks into hollow bricks without affecting the performance of the refractory bricks through the design of the refractory brick matrix. The brick body connection can be limited from multiple directions through the design of the limit strip, positioning hole, sealing block and sealing groove, thereby solving the problem that the traditional brick body connection is prone to loosening and deflection, which easily causes heat loss and poor insulation effect.

[0013] 2. The present invention can effectively enhance the connection strength of the brick body through the design of the inner lining skeleton. The matching design of the heat storage cavity and the heat preservation cavity is helpful to save brick materials and reduce production costs on the one hand, and on the other hand, it helps to enhance the heat storage and heat preservation effects of the brick body.

[0014] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The inner walls of the four connecting holes 8 are clamped with lining frames 9, and the material of the lining frames 9 can be selected from metal materials, corundum materials, or insulation boards and other materials.
