Description

Technical Field

[0001] This utility model relates to the field of N1 clay brick technology, and in particular to an N1 clay brick for baking ovens. Background Technology

[0002] Most baking furnaces (such as ceramic kilns and certain metallurgical or chemical baking furnaces) typically operate at temperatures between 1200°C and 1400°C. N1 clay bricks, with their load softening point (≥1400°C) and refractoriness (≥1750°C), fully meet these temperature requirements, even offering a certain safety margin. N1 clay bricks also exhibit resistance to fumes, dust, and some weakly acidic media generated during the baking process. Therefore, under the premise of meeting usage requirements, N1 clay bricks are a very cost-effective choice. Traditional baking furnaces typically use rectangular, L-shaped, or T-shaped N1 clay bricks during construction. However, for the arched section of the furnace roof, inaccurate positioning between bricks often results in the overall structural strength failing to meet design requirements, thus shortening the furnace's service life. Based on this, this invention proposes an N1 clay brick for baking furnaces. Utility Model Content

[0003] The purpose of this invention is to provide an N1 clay brick for baking ovens, which solves the problems mentioned above.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses an N1 clay brick for baking ovens, comprising a wall, an arched brick at the upper end of the wall, an axe brick on the oblique surface of the arched brick, and an axe brick on the side of the axe brick away from the arched brick. The wall, the arched brick, the axe brick and the axe brick are connected together by diagonal bracing bricks.

[0006] Furthermore, the arch foot bricks are knife-handle shaped arch foot bricks, with the thickness of the bricks on the sloping side gradually decreasing from top to bottom, while the non-stressed side remains vertical.

[0007] Furthermore, the arch foot brick includes an arch foot brick body, the bottom of the arch foot brick body is provided with a groove, and the top of the wall is provided with a protrusion that matches the groove; a limiting groove is provided at the center of the inclined side brick body of the arch foot brick body, and a limiting block matching the limiting groove is provided on the outer side wall of the axe brick; a positioning groove is provided on the right side wall of the arch foot brick body.

[0008] Furthermore, symmetrical protrusions are provided on the inclined side bricks of the arch foot brick body, and anti-displacement grooves matching the protrusions are provided on the outer side wall of the axe brick.

[0009] Furthermore, the inclined support brick includes an inclined support brick body, and a positioning block that mates with the positioning groove one is provided on the left side wall of the inclined support brick body; a positioning protrusion two is provided on the top inclined surface of the inclined support brick body, and a positioning groove two that mates with the positioning protrusion two is provided on the bottom of the axe brick one; a positioning protrusion three is provided on the upper end surface of the inclined support brick body, and a positioning groove three that mates with the positioning protrusion three is provided on the side wall of the axe brick two; a positioning protrusion one is provided on the bottom of the inclined support brick body, and a positioning groove four that mates with the positioning protrusion one is provided on the upper end surface of the wall.

[0010] Furthermore, the right side wall of the inclined support brick has an inwardly concave arc surface structure.

[0011] Furthermore, the length of the second axe brick is longer than the length of the first axe brick.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] This utility model of a baking oven uses N1 clay bricks to connect the wall, arch foot bricks, and axe bricks (one and two) together via diagonal bracing bricks. This not only improves construction quality and efficiency but also increases the load-bearing strength of the diagonal bracing bricks. Furthermore, the wall, arch foot bricks, diagonal bracing bricks, and axe bricks (one and two) achieve rapid positioning and "mechanical interlocking" through grooved protrusions, preventing arch foot misalignment and asymmetry due to human error during construction. This reduces the risk of stress concentration later on. Simultaneously, physical constraints limit the relative sliding or misalignment of the arch foot bricks with adjacent bricks, maintaining the initial designed stress posture, preventing loose connections and widening gaps, and extending the structural lifespan. In summary, this utility model of a baking oven using N1 clay bricks ensures the safe transfer of the arch load and reduces deviations during construction and use through precise positioning and constraints, ultimately achieving safe, stable, and durable use of the baking oven.

[0021] like Figure 1-3 As shown, an N1 clay brick for a baking oven includes a wall 1. An arched brick 2 is provided at the upper end of the wall 1. An axe-shaped brick 3 is provided on the oblique cut surface of the arched brick 2. An axe-shaped brick 4 is provided on the side of the axe-shaped brick 3 away from the arched brick 2. The wall 1, the arched brick 2, the axe-shaped brick 3 and the axe-shaped brick 4 are connected together by diagonal bracing bricks 5.

[0022] The arch foot brick 2 is a knife-handle shaped arch foot brick. The thickness of the brick on the sloping side gradually decreases from top to bottom, and the non-stressed side remains vertical. The vertical load it bears (such as its own weight and the upper load) will be converted into horizontal thrust and vertical pressure on the arch foot.

[0023] The arch foot brick 2 includes an arch foot brick body 201. A groove 202 is formed at the bottom of the arch foot brick body 201. A boss that mates with the groove 202 is provided at the top of the wall 1, enabling rapid positioning and construction, as well as mechanical interlocking, improving connection strength and preventing displacement. A limiting groove 204 is formed at the center of the inclined side brick of the arch foot brick body 201. A limiting block matching the limiting groove 204 is provided on the outer side wall of the axe brick 3, improving connection strength and preventing displacement. A positioning groove 205 is formed on the right side wall of the arch foot brick body 201.

[0024] The inclined side bricks of the arch foot brick 201 are symmetrically provided with protrusions 203, and the outer side wall of the axe brick 3 is provided with anti-displacement grooves that match the protrusions 203, thereby improving the anti-displacement strength and mechanical interlocking performance.

[0025] The inclined support brick 5 includes an inclined support brick body 501. A positioning block 503, which mates with the positioning groove 205, is provided on the left side wall of the inclined support brick body 501, allowing for quick positioning and connection of the inclined support brick 5. A positioning protrusion 2 504 is provided on the top inclined surface of the inclined support brick body 501, and a positioning groove 2, which mates with the positioning protrusion 2 504, is provided on the bottom of the axe brick 3. A positioning protrusion 3 505 is provided on the upper surface of the inclined support brick body 501, and a positioning groove 3, which mates with the positioning protrusion 3 505, is provided on the side wall of the axe brick 4. A positioning protrusion 1 502 is provided on the bottom of the inclined support brick body 501, and a positioning groove 4, which mates with the positioning protrusion 1 502, is provided on the upper surface of the wall 1. The positioning protrusions 1 502 and 3 505 prevent the inclined support brick 5 from shifting outward under thrust, ensuring the stability and strength of the connection. The positioning block 503 and the positioning protrusion 504 further prevent relative sliding or misalignment between the arch foot brick 2 and the axe brick 3, preventing loosening of the connection and widening of gaps, and extending the service life of the structure.

[0026] The right side wall of the inclined bracing brick 501 has an inwardly concave arc surface structure, which forms a complete arc structure with the arch, ensuring connection strength while improving aesthetics.

[0027] The length of the second axe brick 4 is longer than the length of the first axe brick 3, and the excess length is flush with the diagonal brace brick 5.

[0028] The diagonal brace 5, together with the arch foot brick 2, improves the ability to transfer loads, resist thrust, and prevent structural instability. At the same time, it connects the wall 1, arch foot brick 2, axe brick 1 3, and axe brick 2 4 together to form an integral structure, ensuring the overall stability, reasonable stress distribution, and reliable construction of the arch structure.

[0029] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
