Description

Technical Field

[0001] This utility model relates to the field of refractory brick technology, specifically to a high-density magnesium iron aluminum spinel sand brick structure. Background Technology

[0002] Currently, magnesia-based refractory bricks mainly include low-chromium bricks, dolomite bricks, magnesia-zirconium bricks, spinel-modified bricks, and various special magnesia bricks. In order to meet the development needs of high-density refractory bricks for tunnel kilns, spinel refractory materials have been widely used. The raw materials used for high-density refractory bricks mainly include high-purity magnesia sand with a magnesium oxide content of 97%, iron-aluminum spinel, magnesia-iron sand, and magnesia-aluminum spinel sand. These raw materials are mixed twice and then sintered in a tunnel kiln to form high-density magnesia-iron-aluminum spinel sand bricks. However, the traditional high-density magnesia-iron-aluminum spinel sand bricks have a relatively simple structure, mostly rectangular or other solid block cubes. They cannot be quickly positioned and spliced ​​in the horizontal and vertical directions, making construction inconvenient. They are also prone to deformation at high temperatures, leading to loosening and cracking of the mortar joints, which affects the stability and service life of the masonry. In view of this, in-depth research was conducted on the above problems, which led to this case. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a high-density magnesium-iron-aluminum spinel sand brick structure, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-density magnesium-iron-aluminum spinel sand brick structure, comprising a brick block made of high-density magnesium-iron-aluminum spinel sand as the base material, the brick block having a cuboid structure, a top limiting protrusion provided at the top of the brick block, a bottom limiting groove provided at the bottom of the brick block corresponding to the position of the top limiting protrusion, a side limiting protrusion provided on one side of the brick block, a side limiting groove provided on the other side of the brick block corresponding to the position of the side limiting protrusion, a plurality of through holes provided in the brick block along the vertical direction, horizontal protrusions symmetrically provided on both sides of the top limiting protrusion, a positioning groove provided on the lower end face of the brick block corresponding to the position of the horizontal protrusion, and a reinforcing groove provided between the top limiting protrusion and the horizontal protrusion.

[0005] The cross-sections of the aforementioned top limiting protrusion and side limiting protrusion are both isosceles trapezoids.

[0006] The aforementioned side limiting protrusions are symmetrically provided with semi-circular reinforcing blocks on both sides, and the side limiting grooves are provided with semi-circular grooves on both sides corresponding to the positions of the semi-circular reinforcing blocks.

[0007] The inner side of the aforementioned semi-circular groove is provided with a vertical reinforcing groove.

[0008] The cross-section of the aforementioned through hole is oblong.

[0009] This invention provides a high-density magnesium-iron-aluminum spinel sand brick structure. The structure of this high-density magnesium-iron-aluminum spinel sand brick features a top-positioning protrusion and a bottom-positioning groove on the brick block. This allows for precise vertical positioning during bricklaying, meaning workers only need to position the bricks during the first layer; subsequent layers can be aligned automatically due to structural cooperation, reducing the need for manual positioning and increasing the construction speed of hollow brick walls. The side-positioning protrusions and corresponding side-positioning grooves on the brick blocks enable rapid alignment between bricks in the same layer, and the interlocking mechanism further enhances the overall structural strength of the finished wall. The horizontal protrusions on both sides of the top-positioning protrusion, in conjunction with the corresponding positioning grooves, further strengthen the connection structure between upper and lower layers of bricks. Several through holes along the vertical direction within the brick block reduce its overall weight while effectively blocking heat transfer, thus improving the kiln's insulation performance after construction.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Refer to the appendix of the instruction manual Figure 1-6 As can be seen, this application specifically designs a high-density magnesium-iron-aluminum spinel sand brick structure, including a brick block 1 made of high-density magnesium-iron-aluminum spinel sand as the base material. The brick block 1 is a cuboid structure. A top limiting protrusion 2 is provided at the top of the brick block 1, and a bottom limiting groove 3 is provided at the bottom of the brick block 1 corresponding to the position of the top limiting protrusion 2. A side limiting protrusion 4 is provided on one side of the brick block 1, and a side limiting groove 5 is provided on the other side of the brick block 1 corresponding to the position of the side limiting protrusion 4. Several through holes 6 are provided in the brick block 1 along the vertical direction. Horizontal protrusions 7 are symmetrically provided on both sides of the top limiting protrusion 2. A positioning groove 8 is provided on the lower end face of the brick block 1 corresponding to the position of the horizontal protrusion 7. A reinforcing groove 9 is provided between the top limiting protrusion 2 and the horizontal protrusion 7. The top limiting protrusion 2 and the bottom limiting groove 3 on the brick block 1 cooperate to build the brick block 1. During construction, vertical positioning is performed, so that workers only need to locate the first layer of bricks. The second and subsequent layers can be aligned with each other through structural cooperation, reducing the need for workers to locate the bricks and thus increasing the construction speed of hollow brick walls. The limiting protrusions on the sides of the brick block 1 cooperate with the corresponding side limiting grooves 5 to achieve rapid centering and construction of brick blocks 1 at the same level. The interlocking cooperation mode can further improve the overall structural strength of the wall after construction. The horizontal protrusions 7 on both sides of the top limiting protrusion 2 cooperate with the corresponding positioning grooves 8 to further enhance the connection stability between the upper and lower layers of brick blocks 1. The several through holes 6 provided in the vertical direction inside the brick block 1 can effectively block heat transfer while reducing the overall weight of the brick block 1, thereby improving the heat preservation performance of the kiln after construction.

[0019] In the specific implementation process, as a preferred setting, the cross-sections of the top limiting protrusion 2 and the side limiting protrusion 4 are both isosceles trapezoids, and the mortar joints are surface-fitted, with a large contact area and a more stable connection.

[0020] In the specific implementation process, as a preferred setting, the side limiting protrusion 4 is provided with semi-circular reinforcing blocks 10 symmetrically on both sides, and the side limiting groove 5 is provided with semi-circular grooves 11 on both sides corresponding to the semi-circular reinforcing blocks 10. The semi-circular reinforcing blocks 10 and the semi-circular grooves 11 are connected by a plug-in joint, which can further improve the structural strength of the connection position.

[0021] In the specific implementation process, as a preferred setting, the inner side of the semi-circular groove 11 is provided with a vertical reinforcement groove 129, which facilitates the rapid insertion of vertical reinforcement and improves the efficiency of construction operations.

[0022] In practice, as a preferred option, the cross-section of the through hole 6 is oblong, which ensures a reliable structure and makes demolding during production and processing more convenient.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
