At present, such structures commonly used in kiln bodies are mostly made of steel materials. Such materials not only have a high construction cost, but also have limited high-temperature resistance. They are extremely easy to be damaged and deformed under the wear of materials and the erosion of high-temperature air flow for a long time, affecting normal feeding production. At the same time, it is difficult to achieve re-maintenance, increasing the maintenance cost. Content of the Utility Model

The wall structure is formed by splicing and piling up a first module and a second module, has good high-temperature resistance, and after being damaged, local areas can be replaced and maintained, reducing the maintenance cost and the maintenance difficulty.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is as follows: including a first module and a second module. A plurality of the first modules and the second modules are respectively spliced in sequence to form an annular wall, and multiple groups of the walls are stacked in the height direction to form a kiln body. The diameter of the wall formed by splicing the first modules is larger than the diameter of the wall formed by the second modules. Both the first module and the second module are provided with holes.

[0008] Preferably, an inclined ventilation surface is arranged inside the hole.

[0021] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0022] Specific Embodiment 1: In combination with Figures 1-5As shown in the figure, a high-temperature resistant wall structure that can pass through airflows includes: a first module 1 and a second module 2. A plurality of first modules 1 and second modules 2 are sequentially spliced to form an annular wall structure, and multiple groups of walls are stacked in the height direction to form a kiln body structure. The diameter of the wall formed by splicing the first modules 1 is larger than the diameter of the wall formed by the second modules 2. Both the first module 1 and the second module 2 are provided with holes 3;

[0023] A plurality of first modules are sequentially spliced end to end to form an annular first wall, and at the same time, a plurality of second modules are spliced end to end to form an annular second wall. The diameter of the second wall is smaller than the diameter of the first wall. The two cooperate to jointly form a kiln body structure for materials to pass through. The material is located in the annular channel between the two. High-temperature or low-temperature airflows pass through the holes on the second cavity to contact the material, and after penetrating the material, they are discharged through the holes on the first wall to achieve the treatment of the material. At the same time, the wall structure is composed of multiple modules spliced together. Compared with the wall made of steel, after damage occurs, the modules in the area can be repaired and replaced, reducing the operation difficulty and maintenance cost. Moreover, the spliced and stacked structure is convenient for construction and installation.

[0024] In a preferred embodiment, in combination with Figure 2 and Figure 4 As shown in the figure, on the front and rear splicing end faces of the first module 1 and the second module 2, there are respectively provided clamping platforms 4, and the positions of the two clamping platforms 4 are arranged in a staggered manner, presenting a "Z" shape as a whole from the top view. During the end-to-end splicing process, the clamping platform on the front end face of the module forms a clamped state with the clamping platform on the rear end face of another module. After splicing to form an annular wall, it has stable support.

[0025] In a preferred embodiment, in combination with Figure 3 and Figure 5 As shown in the figure, on the upper and lower stacking end faces of the first module 1 and the second module 2, there are respectively provided a convex platform 5 and a groove 6. When stacking in the height direction, the convex platform above the module cooperates with the groove of the module located above to quickly achieve splicing positioning, reduce the installation difficulty, and improve the splicing efficiency.

[0026] In a preferred embodiment, the cross-sectional shape of the convex platform 5 is processed into a trapezoid, which is convenient for alignment and positioning.

[0027] In a preferred embodiment, in combination with Figure 3 and Figure 5 As shown in the figure, inside the hole 3, there is an inclined ventilation surface 301, which is convenient for guiding high-temperature (low-temperature) airflows and at the same time avoids the problem of materials falling out from the holes.

[0028] In a preferred embodiment, in combination with Figure 1 、 Figure 3 and Figure 5As shown, the ventilation surfaces 301 on the first module 1 and the ventilation surfaces 301 on the second module 2 are arranged in opposite inclined directions. That is, on the first wall formed by splicing the first modules, the ventilation surfaces point to the second wall formed by splicing the second modules, while the ventilation surfaces of the second wall point to the inner circle of the first wall. When materials pass between the two, it can not only prevent the materials from falling out through the holes, but also realize the guidance of the airflow through. The structural design is reasonable.

[0029] The bodies of the first module 1 and the second module 2 are made of refractory materials. Preferably, a corundum-mullite brick structure can be used, which has good overall strength, as well as good fire resistance and structural strength, meeting the construction and production requirements of the kiln body.

Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention.
