Description

Technical Field

[0001] The utility model relates to the technical field of carbon baking furnaces, in particular to a transverse wall composite brick for a carbon baking furnace. Background Art

[0002] A carbon baking furnace is a thermal equipment that indirectly heats various carbon products after high-pressure forming at a specified baking temperature under air-tight conditions, thereby improving the electrical and thermal conductivity of the products and increasing the strength of the products. The carbon baking furnace is divided into a furnace bottom, side walls, fire channel walls, cross walls, a furnace top and a flue according to its structure.

[0003] The existing public technology has a publication number of CN216245564U. A cross wall of a roasting furnace fire channel is formed by stacking layered wall units, wherein the layered wall units include A wall units and B wall units. The stacking is formed by alternating stacking of A wall units and B wall units. The two units have the same appearance and shape but are respectively composed of different bricks. The finally combined wall structure is stable and has a long service life.

[0004] However, the above patent still has certain disadvantages when in use: the existing bricks for transverse walls mostly have a relatively flat and simple surface, and multiple bricks need to be connected by adhesives and other materials, which are prone to produce large gaps due to thermal expansion and contraction. At this time, the hot air inside the roasting furnace is easy to escape from the gaps, resulting in the overall thermal insulation effect is not very ideal, and the generation of gaps will also cause major changes in the wall, thereby affecting the overall strength of use, and the use effect is not very good.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

Figure 1-3As shown, according to the embodiment of the utility model, the cross wall composite brick for the carbon roasting furnace comprises a composite brick body 1, and the surface positions of the four sides of the composite brick body 1 are respectively provided with short card slots 5 and long card slots 6, and a long strip 2 is installed at the surface position of the composite brick body 1 behind the short card slot 5, and a short strip 7 is installed at the surface position of the composite brick body 1 in front of the long card slot 6, and a docking groove 3 is opened at the surface position of the long strip 2 and the short strip 7, and a docking strip 4 is provided on one side of the docking groove 3, and the length of the long strip 2, the short strip 7, the docking strip 4 on the surface of the long strip 2, and the docking strip 4 on the surface of the short strip 7 is set to ensure that the lengths can be passed through after thermal expansion and contraction. The difference can form a blocking space, thereby reducing the generation of gaps and forming multiple partitions between the bricks. This can not only enhance the overall connection strength, but also increase the movement path of hot air due to the existence of partitions, thereby extending the retention time of hot air, reducing the heat dissipated to the outside, and improving the overall thermal insulation effect. The manufacture of the brick body can be roughly produced through a mold, and then the honeycomb insulation layer is constructed, and then the solid layer on the top is connected, and finally the whole is fired. The above operations are for reference only. Personnel can change the process according to production experience and different production equipment.

When the two are plugged in correspondingly, the docking groove 3 and the docking strip 4 on the surface of the long strip 2 and the short strip 7 can be plugged in for the second time. In this way, the overall connection strength can be effectively improved through multiple groups of mortise and tenon connections, and the length of the connecting piece at the rear of the brick body is greater than the length of the connecting piece at the front. In this way, when thermal expansion and contraction occur, the hot air flowing through the gap can be blocked by the long strip 2 to reduce the amount of overflow, and the bending area formed by the docking strip 4 and the docking groove 3 can also prolong the retention time of the hot air and reduce the amount of overflow, which can effectively improve the overall thermal insulation effect, and a honeycomb insulation layer 9 is provided inside the brick body.
