Description

Technical Field

[0001] The utility model relates to the technical field of refractory bricks, in particular to a lock-type refractory brick. Background Art

[0002] Refractory bricks are refractory materials with certain shapes and sizes. According to the preparation process method, refractory bricks can be divided into fired bricks, unfired bricks, fused cast bricks, and refractory insulation bricks; according to the shape and size, they can be divided into standard bricks, ordinary bricks, special-shaped bricks, etc. They can be used as high-temperature building materials and structural materials for building kilns and various thermal equipment. For example, they are applied to hot blast stoves, which are pressure-bearing containers lined with refractory materials inside a metal shell. The structure of the refractory materials that make up them is mainly composed of multiple refractory bricks connected to each other through corresponding locking structures.

[0003] Most of the existing refractory bricks are rectangular bricks. When these refractory bricks are laid together, the opposite surfaces of the refractory bricks are all flat. Therefore, whether they are laid in alignment or staggered, the brick joints are all straight joints, and the bonding performance between the bricks is poor, and problems such as loosening and falling off are likely to occur, and they are not stable enough to use. Summary of the Invention

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A lock-type refractory brick includes a refractory brick body. The two sides of the refractory brick body along the length direction are respectively a first wavy surface and a second wavy surface, and adjacent refractory brick bodies are detachably connected through the first wavy surface and the second wavy surface; a long groove is opened on one side of the refractory brick body along the width direction, and a mortar layer is filled between the long groove and the adjacent refractory brick body; a protrusion is arranged on the upper surface of the refractory brick body, and a groove is opened on the lower surface of the refractory brick corresponding to the protrusion.

[0007] In some embodiments, two protrusions are symmetrically arranged about the center line of the width direction of the refractory brick body, and the two protrusions are located on the center line of the length direction of the refractory brick body, and the grooves are arranged in one-to-one correspondence with the protrusions.

[0008] In some embodiments, a plurality of blind holes are further opened on the upper surface of the refractory brick body. The plurality of blind holes are divided into two groups and are respectively located on both sides of the protrusion, and the two groups of blind holes are symmetrically arranged about the center line of the length direction of the refractory brick body.

[0009] In some embodiments, both ends of the long groove penetrate through the first wavy surface and the second wavy surface, and the long groove is a concave rectangular groove.

[0010] In some embodiments, the shapes of the first wavy surface and the second wavy surface match. The first wavy surface includes a first wave trough and a first wave peak, and the second wavy surface includes a second wave trough and a second wave peak. The first wave trough and the second wave peak are arranged opposite to each other, and the second wave trough and the first wave peak are arranged opposite to each other.

[0011] In some embodiments, both the protrusion and the groove are hemispherical, and the diameter of the protrusion is equal to the diameter of the groove.

[0012] Compared with the prior art, the present utility model provides a snap - type refractory brick, which has the following beneficial effects.

[0013] When the snap - type refractory brick provided by the present utility model is being stacked, it is stacked layer by layer from bottom to top. When two adjacent refractory brick bodies in the same layer are stacked, the first wavy surface of one refractory brick body is engaged with the second wavy surface of the other refractory brick body. Then, the mortar prepared in advance through proportioning and stirring is filled into the long groove to complete the filling of the mortar layer, and the adjacent two refractory bricks are bonded. And so on, until a layer of refractory bricks is stacked. Repeat the above steps to stack the upper layer of refractory bricks. The upper and lower adjacent refractory brick bodies are fitted through the arranged protrusions and grooves, which improves the convenience during stacking. At the same time, the blind holes are also filled with mortar to bond with the refractory brick body of the upper layer; when multiple layers of refractory bricks are stacked, a mutually locked structure is formed between adjacent refractory bricks in the same layer, which can prevent the loosening and falling off after the combination connection of the refractory bricks and improve the stability of the combined refractory bricks.

[0014] The parts not involved in this device are the same as those in the prior art or can be implemented by using the prior art. When the present utility model is used for staggered joint masonry, the masonry structure is stable.

[0015] Other advantages, objectives and features of the present utility model will be described to some extent in the subsequent specification; and to some extent, based on the study of the following text, they will be obvious to those skilled in the art; or, they can be learned from the practice of the present utility model.

The two sides of the refractory brick body 1 along the length direction are respectively a first wavy surface 2 and a second wavy surface 3. Adjacent refractory brick bodies 1 are detachably connected through the first wavy surface 2 and the second wavy surface 3; a long groove 4 is opened on one side of the refractory brick body 1 along the width direction, and a mortar layer 5 is filled between the long groove 4 and the adjacent refractory brick body 1; a protrusion 6 is arranged on the upper surface of the refractory brick body 1, and a groove 7 is opened on the lower surface of the refractory brick corresponding to the protrusion 6.

[0024] Specifically, two protrusions 6 are symmetrically arranged about the center line of the refractory brick body 1 in the width direction, and the two protrusions 6 are located on the center line of the refractory brick body 1 in the length direction, and the grooves 7 are arranged in one-to-one correspondence with the protrusions 6. The design of the groove 7 for the protrusion 6 enables the protrusion 6 of one refractory brick body 1 to be inserted into the groove 7 of another refractory brick body 1 during staggered joint masonry, ensuring the overlap between the upper and lower refractory bricks.

[0025] Furthermore, a plurality of blind holes 8 are also opened on the upper surface of the refractory brick body 1. The plurality of blind holes 8 are divided into two groups and are respectively located on both sides of the protrusion 6, and the two groups of blind holes 8 are symmetrically arranged about the center line of the refractory brick body 1 in the length direction.

[0026] In this embodiment, both ends of the long groove 4 penetrate through the first wavy surface 2 and the second wavy surface 3, and the long groove 4 is a concave rectangular groove. By filling the mortar layer 5 inside the long groove 4, adjacent two refractory bricks are bonded.
