Technical Field

[0001] The utility model relates to the technical field of graphite carbon bricks, in particular to a novel corrosion-resistant graphite carbon brick. Background Art

[0002] Graphite carbon brick is a kind of brick made of graphite and carbon material, which has good high temperature resistance and corrosion resistance. Graphite carbon brick is usually used for the lining of high temperature industrial equipment and the construction of the interior of the furnace, which can effectively resist high temperature, chemical corrosion and thermal shock.

[0003] In the existing structure, due to the excellent performance of graphite carbon bricks, they are generally used in industries that require high temperature environments, such as metallurgy, glass, and ceramics. They are an extremely important refractory material. However, when laying graphite carbon bricks, before the connecting material is completely solidified, the overall continuity is poor and relatively fragile. If the graphite carbon bricks are accidentally touched, they may cause dislocation and affect the subsequent overall thermal insulation effect. In view of this, we have proposed a new type of corrosion-resistant graphite carbon brick. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a new type of corrosion-resistant graphite carbon brick, which can solve the problem of poor overall connectivity before the connecting material is completely solidified.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of corrosion-resistant graphite carbon brick, comprising a brick body, a protrusion fixedly connected to the right surface of the brick body, the upper surface of the protrusion extends out of the upper surface of the brick body, a groove matched with the protrusion is provided on the left surface of the brick body, an insulation cavity is provided inside the brick body, a connecting block is fixedly connected to the bottom wall of the insulation cavity, second grooves are provided on the upper and lower side surfaces of the brick body, the side adjacent to the two second grooves extends into the interior of the insulation cavity, the upper surface of the connecting block is also provided with a second groove extending out of its lower surface, the interiors of the three second grooves are connected, and the front and rear side surfaces of the brick body are respectively fixedly connected with heat-conducting protrusions.

[0006] Preferably, two inclined plates are fixedly connected to the bottom wall of the temperature-isolating chamber, upper ends of the two inclined plates are fixedly connected to the top wall of the temperature-isolating chamber, and the two inclined plates are arranged in a mirror image.

[0007] Preferably, two L-shaped reinforcement plates are fixedly connected to the bottom wall of the thermal insulation chamber, and the vertical plates of the two L-shaped reinforcement plates are respectively fixedly connected to the front and rear inner walls of the thermal insulation chamber.

[0008] Preferably, one side surface of the two L-shaped reinforcing plate vertical plates that are adjacent to each other is fixedly connected to a connecting plate, and one side surface of the two connecting plates that are adjacent to each other is fixedly connected to the two inclined plates.

[0009] Preferably, two reinforcing ribs are fixedly connected to the left and right inner walls of the temperature insulation chamber respectively, and adjacent ends of the four reinforcing ribs are fixedly connected to the connecting block.

[0010] Preferably, an interlayer is provided inside the brick body, and a high-strength fiber mesh is provided inside the interlayer.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) When the new type of corrosion-resistant graphite carbon brick is used to connect multiple bricks, the protrusion on the brick is inserted into the interior of the slot. At the same time, because the bricks are usually stacked in an interlaced manner for overall stability, after two bricks are connected, another brick is placed above the intersection of the lower bricks, and the protruding part of the brick is inserted into the interior of the second slot of the upper brick. Then, the bricks are connected and stacked in sequence. Through the above structure, not only can the protrusion, the slot and the second slot be used to complete the positioning and alignment when the bricks are stacked, but also one protrusion can be used to connect the slot and the second slot at the same time, so that each brick is connected to the other two bricks, and each brick is locked by the other two bricks, thereby improving the overall strength after the connection and during operation.

[0013] (2) The new type of corrosion-resistant graphite carbon brick uses a triangle composed of two mirror-image inclined plates to avoid the problem of strength reduction caused by hollowing out the inside of the brick body, thereby enhancing the overall strength of the brick body. At the same time, an L-shaped reinforcing plate is used to support the side wall of the brick body to avoid the side wall of the brick body from tilting, and the inclined plate and the L-shaped reinforcing plate are connected with the help of a connecting plate to disperse the forces acting on both. The overall strength of the brick body is improved by setting reinforcing ribs, and the overall crack resistance of the brick body is improved by a high-strength fiber mesh inside the interlayer to avoid rapid spread of cracks on the surface. Through the above structure, not only can the overall strength of the brick body be improved by using reinforcing ribs, inclined plates and L-shaped reinforcing plates, but the crack resistance of the brick body can also be improved by using a high-strength fiber mesh to improve the overall stability.
