Description

Technical Field

[0001] The utility model relates to the technical field of refractory bricks, in particular to a refractory brick with enhanced connectivity at brick joints. Background Art

[0002] Refractory bricks are also called fire bricks. They are refractory materials made by burning refractory clay or other refractory raw materials. They are light yellow or brown in color. They are mainly used for building smelting furnaces. They can withstand high temperatures of 1,580℃-1,770℃. They can be used as high-temperature building materials and structural materials for building kilns and various thermal equipment. They can withstand various physical and chemical changes and mechanical effects at high temperatures. For example, refractory clay bricks, high-alumina bricks, silica bricks, magnesia bricks, etc.

[0003] When the existing refractory bricks are in use, they will expand due to the high temperature, thereby squeezing the adjacent bricks, increasing the gap between the bricks, and being detrimental to the insulation of the wall. The patent CN110274478B discloses a refractory brick, which is a prefabricated part composed of structures such as clamping columns and recesses to improve the tightness of the connection between the bricks, so that the adjacent bricks can be relatively fixed after stacking, reducing the situation of the refractory bricks falling off during use. However, after the bricks expand, they will squeeze the snap-fitting unit, so that the snap-fitting parts are squeezed out, and the desired effect cannot be achieved. Therefore, it is necessary to solve this problem. Utility Model Content

[0004] The main purpose of the utility model is to provide a refractory brick which can strengthen the connectivity of brick joints.

[0005] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0006] A refractory brick for strengthening the connection between brick joints, comprising a brick body,

[0007] The outer wall of the brick body is symmetrically provided with buckling protrusions and buckling grooves around the periphery;

[0008] The buckling protrusion includes a buckling ball head and a buckling column, and the buckling groove includes a columnar groove and a ball head groove;

[0009] A plurality of expansion grooves are provided on the top and bottom of the brick body, and the diameter of the expansion grooves is 2 mm.

[0010] Preferably, the snap-fit ​​ball head is snap-fitted with the ball head groove, the snap-fit ​​column is snap-fitted with the cylindrical groove, and the diameter of the cylindrical groove is greater than the diameter of the snap-fit ​​column.

[0011] Preferably, the interior of the brick body is composed of an amorphous refractory material layer and a shaped refractory material layer, and the amorphous refractory material layer surrounds and is embedded in the outer periphery of the shaped refractory material layer.

[0012] Preferably, the buckling protrusion and the buckling groove are both made of the shaped refractory material layer and are an integrally formed structure.

[0013] Preferably, the amorphous refractory material layer and the shaped refractory material layer are bonded by gypsum.

[0014] Beneficial technical effects of the utility model:

[0015] The utility model provides snap-fit ​​grooves and snap-fit ​​protrusions on traditional refractory bricks, which can not only achieve a tight connection between the refractory bricks, but also the snap-fit ​​protrusions can work together with the snap-fit ​​ball head and the snap-fit ​​column. When the brick body expands at high temperature, the spherical groove is squeezed and the space becomes smaller, which improves the wrapping effect on the snap-fit ​​column and further improves the connection shape between adjacent brick bodies. At the same time, the interior of the brick body is composed of a mixture of shaped materials and unshaped materials, which can reduce the deformation expansion of the refractory bricks and reduce the squeezing force on adjacent brick bodies.

[0022] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0023] like Figure 1-Figure 4As shown, the present embodiment provides a refractory brick for strengthening the connectivity of brick joints, including a brick body 1, wherein the outer wall of the brick body 1 is symmetrically provided with snap-fit ​​protrusions 2 and snap-fit ​​grooves 3; the snap-fit ​​protrusions 2 include snap-fit ​​ball heads 7 and snap-fit ​​columns 8, and the snap-fit ​​grooves 3 include columnar grooves 10 and ball head grooves 9. The snap-fit ​​ball heads 7 play a limiting role when connected to the ball head grooves 9, and can keep the snap-fit ​​columns 8 at the bottom limited, so that the snap-fit ​​columns 8 can easily slide into the columnar grooves 10 that are larger than their own sizes.

[0024] The buckling ball head 7 is buckled and installed in the ball head groove 9 , and the buckling column 8 is buckled and installed in the cylindrical groove 10 . The diameter of the cylindrical groove 10 is greater than the diameter of the buckling column 8 .

[0025] The interior of the brick body 1 is composed of an amorphous refractory layer 5 and a shaped refractory layer 6. The amorphous refractory layer 5 surrounds and is embedded in the outer periphery of the shaped refractory layer 6. The composition of the amorphous refractory layer 5 is a mixed powdery particle composed of a variety of aggregates or aggregates and one or more binders, and the composition of the shaped refractory layer 6 is a product of a shaped structure.

[0026] The buckling protrusion 2 and the buckling groove 3 are made of a shaped refractory material layer 6 and are an integrally formed structure. A plurality of expansion grooves 4 are provided at the top and bottom of the brick body 1. The diameter of the expansion grooves 4 is 2 mm. When the top of the brick body 1 expands and cracks, the expansion grooves 4 can play a buffering role and reduce the width of the cracks.

[0027] Working principle of this device:

[0028] Step 1: When processing the brick body 1, the unshaped refractory material layer 5 and the shaped refractory material layer 6 are placed in a fixed area through a mold, and then fired and shaped;

[0029] Step 2: When the brick bodies 1 are used to build a wall, refractory mud is applied to the outer walls of the adjacent brick bodies 1, and then the buckling protrusions 2 are inserted into the buckling grooves 3 to achieve a tight connection. After the refractory mud is dried, it can be shaped and used at high temperature;

[0030] Step 3: When the brick body 1 is used at high temperature, the shaped refractory material layer 6 will expand and deform, and then the columnar groove 10 and the ball head groove 9 in the buckling groove 3 will be deformed, making the internal space smaller, increasing the binding force on the buckling column 8, and thus maintaining the original tightness between the brick bodies 1 to avoid affecting the thermal insulation of the refractory wall.

[0031] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
