DETAILED DESCRIPTION

[0019] The following is in conjunction with the appendix Figs. 1-3 The specific embodiments of this utility model will be described in further detail.

[0020] like Figs. 1-3 As shown, this utility model discloses a refractory brick with flexural and compressive strength, comprising a refractory material layer 10, a lightweight heat insulation layer 20, and a heat-insulating carbon fiber plate layer 30.

During processing, the refractory material mixture is placed in the mold of the refractory material layer 10, and the lightweight material mixture is placed in the mold of the lightweight heat insulation layer 20. A partition is provided between the two molds. After the refractory material mixture in the refractory material layer 10 and the lightweight heat insulation layer 20 are placed, the partition is removed, and then the brick is pressed into shape using a brick press. Finally, the heat-insulating carbon fiber plate layer 30 is assembled onto the lightweight heat insulation layer 20. The above is the existing technology and will not be described in detail here.

[0021] In this embodiment, two fastening grooves 21 are provided at both ends of the lightweight heat insulation layer 20 near the side of the heat insulation carbon fiber plate 30. Two fastening plates 31 are integrally formed at both ends of the heat insulation carbon fiber plate 30 and are fastened to the fastening grooves 21. When assembling the heat insulation carbon fiber plate 30, the heat insulation carbon fiber plate 30 can be fastened to the surface of the lightweight heat insulation layer 20 like a cover. A reinforcing rib 40 is movably inserted inside the lightweight heat insulation layer 20. The strength of the lightweight heat insulation layer 20 is increased by setting the reinforcing rib 40. The two ends of the reinforcing rib 40 pass through the two fastening plates 31, which facilitates the limiting of the heat insulation carbon fiber plate 30.

[0022] Specifically, the snap-on plate 31 is provided with a first connecting hole 32, and the lightweight heat insulation layer 20 is provided with a second connecting hole 22 that connects the two snap-on grooves 21. The reinforcing rib 40 is limited within the first connecting hole 32 and the second connecting hole 22. When assembling the heat insulation carbon fiber plate 30, the heat insulation carbon fiber plate 30 can be snapped onto the lightweight heat insulation layer 20, and then the heat insulation carbon fiber plate 30 can be limited by inserting the reinforcing rib 40 into the first connecting hole 32 and the second connecting hole 22. This not only facilitates the installation of the heat insulation carbon fiber plate 30, but also increases the strength of the lightweight heat insulation layer 20.

[0023] In some embodiments, the diameter of the reinforcing rib 40 is smaller than the diameter of the first connecting hole 32 and the second connecting hole 22, and a rubber sleeve 41 is fixedly sleeved on the outer surface of the reinforcing rib 40. The outer wall of the rubber sleeve 41 is in close contact with the inner wall of the first connecting hole 32 and the second connecting hole 22. Through the setting of the rubber sleeve 41, the reinforcing rib 40 can be simply limited under the action of friction.

[0024] In some embodiments, after the heat-insulating carbon fiber plate layer 30 is assembled, the end portions of the reinforcing ribs 40 can also be spot-welded by a welding machine, and the thickness of the end portions of the reinforcing ribs 40 is increased by spot welding, so that the reinforcing ribs 40 are limited between the lightweight heat-insulating layer 20 and the heat-insulating carbon fiber plate layer 30.

[0025] In some embodiments, the inner surface of the refractory material layer 10 is provided with a trapezoidal connecting block 11, and the side of the lightweight heat-insulating layer 20 close to the refractory material layer 10 is embedded with a connecting groove 23 with a trapezoidal structure, and the connecting block 11 is slidingly inserted into the connecting groove 23.

[0026] In order to make the connection of the refractory bricks more firm when they are stacked, the top of the lightweight heat-insulating layer 20 is integrally formed with an embedded block 24, and the bottom of the lightweight heat-insulating layer 20 is embedded with an embedded groove 25, and when the refractory bricks are stacked, the refractory bricks of the upper and lower blocks can be engaged with each other through the embedded block 24 and the embedded groove 25, thereby increasing the tightness of the connection.

[0027] In some embodiments, the inner surface of the heat-insulating carbon fiber plate layer 30 is glued and fixed to the surface of the lightweight heat-insulating layer 20.

[0028] It is worth mentioning that, as shown in Fig. 3 The reinforcing ribs 40 are movably arranged in the interior of the refractory bricks, and when the refractory bricks are stacked, the reinforcing ribs 40 in the interior of the refractory bricks can be partially pulled out and welded with the reinforcing ribs 40 on the adjacent refractory bricks, so that the refractory bricks of the upper and lower layers are engaged with each other through the embedded block 24 and the embedded groove 25, and the adjacent refractory bricks are tightly adjacent through the reinforcing ribs 40, so that the refractory wall formed by the refractory bricks is more firm.
