Description

Technical Field

[0001] This utility model relates to the field of heat storage brick technology, specifically a heat storage modular brick. Background Technology

[0002] In regenerative combustion systems, traditional regenerative modular bricks are honeycomb-shaped and used in combination. In the combustion system, the flame or flue gas passes through the regenerative modular bricks for heat exchange. The regenerative modular bricks in the vertical plane of the flame or flue gas flow and the adjacent regenerative modular bricks in the direction of the flame or flue gas flow are all tightly spliced ​​to ensure that the honeycomb holes of the regenerative modular bricks can be aligned.

[0003] To ensure the flame or flue gas velocity within a reasonable range at the cross-section, a sufficient number of bricks are needed to guarantee the velocity at the flow cross-section. While increasing porosity can be achieved by adding more or larger pores, high porosity leads to decreased mechanical properties and increased susceptibility to breakage. Furthermore, regenerative modular bricks can crack over time, causing internal blockages that affect flame or flue gas velocity and ultimately impact the operation of the entire regenerative combustion system. Therefore, it is necessary to design a more reliable regenerative modular brick. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a heat storage modular brick, which solves the problem that traditional heat storage modular bricks are prone to internal cracking and blockage due to decreased mechanical properties or prolonged use, affecting the flame or flue gas flow rate.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A heat storage modular brick includes a square heat storage brick body, wherein the heat storage brick body is provided with horizontal and vertical support partitions, and the heat storage brick body is provided with through holes running through the front and back evenly in four areas separated by the support partitions.

[0007] The front of both the heat storage brick body and the supporting partition is provided with positioning protrusions, and the back of both the heat storage brick body and the supporting partition is provided with positioning grooves corresponding to the positions of the positioning protrusions.

[0008] The heat storage brick body has splicing protrusions on its top and one side, splicing slots corresponding to the positions of the splicing protrusions on its bottom and the other side, and grooves parallel to the through holes on the outer wall of the heat storage brick body.

[0009] Preferably, the heat storage brick body, supporting partition, positioning protrusion and splicing protrusion are an integral structure.

[0010] Preferably, all four corners of the heat storage brick body are rounded.

[0011] Preferably, the positioning protrusion is located on the front of the heat storage brick body near the four corners and at the center of the front of the supporting partition. The front end of the positioning protrusion is spherical, the positioning groove is circular, and the length of the positioning protrusion is greater than the depth of the positioning groove.

[0012] Preferably, the heat storage brick body has two splicing protrusions on the top and one side, which are arranged symmetrically on the left and right and vertically, respectively. The splicing protrusions are trapezoidal blocks, the splicing grooves are trapezoidal grooves, and the thickness of the splicing protrusions is greater than the depth of the splicing grooves.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The main body of this utility model of heat storage bricks increases structural strength through supporting partitions, making it less prone to breakage and blockage. When the main bodies of the heat storage bricks are spliced, positioning protrusions and splicing protrusions support adjacent main bodies of the heat storage bricks, so that gaps are maintained between them for the flow of flame or smoke. At the same time, the groove design increases the gaps for the flow of flame or smoke. When a local heat storage brick body breaks and becomes blocked, the flame or smoke can continue to flow through the surrounding gaps, reducing the impact on the total flame or smoke flow rate within the cross section. This solves the problem that traditional heat storage modular bricks are prone to internal breakage and blockage due to decreased mechanical properties or prolonged use, which affects the flame or smoke flow rate.

[0020] 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.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a heat storage modular brick, including a square heat storage brick body 1, the four corners of the heat storage brick body 1 are all rounded, the heat storage brick body 1 is provided with horizontal and vertical support partitions 2, and the heat storage brick body 1 is provided with through holes 3 evenly arranged in the four areas separated by the support partitions 2.

[0022] The front of both the heat storage brick body 1 and the supporting partition 2 is provided with positioning protrusions 4, and the back of both the heat storage brick body 1 and the supporting partition 2 is provided with positioning grooves 5 corresponding to the positions of the positioning protrusions 4. The positioning protrusions 4 are located on the front of the heat storage brick body 1 near the four corners and in the center of the front of the supporting partition 2. The front end of the positioning protrusions 4 is spherical, the positioning grooves 5 are circular grooves, and the length of the positioning protrusions 4 is greater than the depth of the positioning grooves 5.

[0023] The top and one side of the heat storage brick body 1 are provided with splicing protrusions 6. The heat storage brick body 1, the supporting partition 2, the positioning protrusions 4 and the splicing protrusions 6 are integrated into one structure. The bottom and the other side of the heat storage brick body 1 are provided with splicing grooves 7 corresponding to the positions of the splicing protrusions 6. The outer wall of the heat storage brick body 1 is also provided with grooves 8 parallel to the through holes 3. There are two splicing protrusions 6 on the top and one side of the heat storage brick body 1, which are respectively symmetrically arranged left and right and symmetrically arranged up and down. The splicing protrusions 6 are trapezoidal blocks and the splicing grooves 7 are trapezoidal grooves. The thickness of the splicing protrusions 6 is greater than the depth of the splicing grooves 7.

[0024] Working principle:

[0025] The horizontally and vertically adjacent heat storage brick bodies 1 are spliced ​​and positioned by splicing protrusions 6 and splicing grooves 7, ensuring they are on the same horizontal and vertical line. The trapezoidal splicing protrusions 6 provide good support stability, which helps to stabilize the splicing and stacking. The vertically adjacent heat storage brick bodies 1 are spliced ​​and positioned by positioning protrusions 4 and positioning grooves 5, ensuring they are on the same vertical horizontal line and ensuring that the positions of their through holes 3 correspond, reducing the flow resistance of flame and flue gas. The support partition 2 inside the heat storage brick body 1 enhances the structure of a single heat storage brick body 1. The increased strength enhances mechanical properties, making it less prone to internal breakage and blockage of flame or smoke flow. The positioning protrusions 4 and splicing protrusions 6 support the horizontally, vertically, and longitudinally adjacent heat storage brick bodies 1, maintaining gaps between them for flame or smoke flow. At the same time, the design of the grooves 8 further increases the gaps for flame or smoke flow in the horizontally and vertically adjacent heat storage brick bodies 1. When a local heat storage brick body 1 breaks and becomes blocked, flame or smoke can continue to flow through the surrounding gaps, thereby reducing the impact on the total flame or smoke flow rate within the cross-section.
