Description

Technical Field

[0001] This utility model relates to the field of clay brick technology, and in particular to a special-shaped clay brick for the fire channel wall of a firing furnace. Background Technology

[0002] In calcining furnaces (especially anode calcining furnaces, cathode calcining furnaces, or ceramic sintering furnaces), the fire channel wall is its core structure, directly bearing the effects of high temperatures, flame erosion, flue gas corrosion, and the chemical action of volatiles in the furnace charge. Using irregularly shaped clay bricks is one of the key technologies for constructing efficient, sealed, and durable fire channel walls. In many cases, corners are constructed using two straight bricks joined at a right angle; however, this design suffers from air leakage and fire spread problems due to misalignment of the joints. Based on this, this invention proposes an irregularly shaped clay brick for the fire channel wall of a calcining furnace. Utility Model Content

[0003] The purpose of this invention is to provide a shaped clay brick for the fire channel wall of a roasting furnace, thereby solving 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 a special-shaped clay brick for the fire channel wall of a roasting furnace, comprising a bottom right-angle brick, several middle right-angle bricks and a top right-angle brick inserted sequentially from bottom to top, with horizontal bricks inserted into the side walls of the bottom right-angle brick, the middle right-angle brick and the top right-angle brick.

[0006] The middle right-angle brick includes a middle brick body, the upper end of which is integrally formed with an L-shaped groove, and the lower end of which is integrally formed with an L-shaped block;

[0007] The top right-angle brick includes a top brick body, and the bottom of the top brick body is integrally formed with a top L-shaped block that matches the L-shaped groove;

[0008] The bottom right-angled brick includes a bottom brick body, and the top of the bottom brick body is integrally formed with a bottom L-shaped groove that matches the L-shaped block.

[0009] Furthermore, a first protrusion and a first dovetail groove are respectively provided on one side wall of the bottom right-angle brick, the middle right-angle brick and the top right-angle brick, and a first groove and a first dovetail block are respectively provided on the other side wall.

[0010] Furthermore, the horizontal brick includes a horizontal brick body, one side of which is provided with a second groove and a second dovetail block that respectively cooperate with the first protrusion and the first dovetail groove, and the other side is provided with a second protrusion and a second dovetail groove that respectively cooperate with the first groove and the first dovetail block.

[0011] Furthermore, the first protrusion and the first groove are positioned on the inner side of the bottom right-angle brick / middle right-angle brick / top right-angle brick, and the first dovetail groove and the first dovetail block are positioned on the outer side of the bottom right-angle brick / middle right-angle brick / top right-angle brick.

[0012] Furthermore, a positioning groove is provided on the upper surface of the intermediate brick, and a positioning block that cooperates with the positioning groove is integrally formed on the lower surface.

[0013] Furthermore, a positioning protrusion that mates with the positioning groove is integrally formed on the lower end surface of the top brick.

[0014] Furthermore, a positioning groove that mates with the positioning block is integrally formed on the upper surface of the bottom brick.

[0015] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0016] This utility model of shaped clay bricks for the fire channel wall of a roasting furnace transforms the traditional right-angle construction, which required two straight bricks to be joined, into a single integral structure. This eliminates vertical mortar joints and avoids air leakage and fire spread problems caused by misaligned joints. In summary, this utility model of shaped clay bricks for the fire channel wall of a roasting furnace solves the construction problem at 90° right-angle turns in the wall, improving the wall's sealing performance, structural stability, and service life.
