[0022] The following will be described in detail with reference to the embodiments of the present utility model with reference to the drawings. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments:

[0024] As Figures 1-10 shown, the combined support structure for kiln furnace load-bearing includes several shed plates 1, toothed columns 2, column cap seats 3, horizontal silicon nitride beams 4, vertical silicon nitride beams 5, and inclined silicon nitride beams 6. The column cap seat 3 is installed at the bottom of the toothed column 2. Several pairs of toothed columns 2 are vertically inserted into the bottom of the vertical silicon nitride beam 5 and form a sheet-shaped frame. Several sheet-shaped frames are arranged side by side. A pair of horizontal silicon nitride beams 4 are horizontally installed at the front and rear ends of the tops of the vertical silicon nitride beams 5 of several sheet-shaped frames. The inclined silicon nitride beam 6 is obliquely installed at the top of the vertical silicon nitride beams 5 of two adjacent sheet-shaped frames. The inclined silicon nitride beam 6 is located between a pair of horizontal silicon nitride beams 4. Several convex teeth 7 are provided on both sides of the toothed column 2 from top to bottom. The shed plate 1 is slidably inserted onto the convex teeth 7 of the opposite pairs of toothed columns 2 between two adjacent sheet-shaped frames.

[0025] Several first mounting holes 9 are provided at the top of the vertical silicon nitride beam 5, and several slots 8 corresponding to the toothed columns 2 are provided at the bottom. The top of the toothed column 2 is inserted into the slot 8. Several second mounting holes 10 are provided at the top of the horizontal silicon nitride beam 4, and the horizontal silicon nitride beam 4 is fixed to the vertical silicon nitride beam 5 by fixing pins passing through the second mounting holes 10 and the corresponding first mounting holes 9. Both ends of the top of the inclined silicon nitride beam 6 are respectively provided with third mounting holes 11, and the inclined silicon nitride beam 6 is fixed to the vertical silicon nitride beam 5 by fixing pins passing through the third mounting holes 11 and the corresponding first mounting holes 9. Diagonal corners at the bottom of the column cap seat 3 are respectively provided with fourth mounting holes 12, and the column cap seat 3 is fixed to the kiln car support plate by fixing pins passing through the fourth mounting holes 12.

[0026] The shed plate 1 plays an important role in the ceramic firing process, used to support and isolate the ceramic products placed in the kiln furnace, ensuring that the hot air can circulate evenly, so as to achieve the effect of uniform firing. Specifically, the shed plate 1 can be a porous shed plate, a non-porous shed plate, a trough-shaped shed plate, etc. Which type of shed plate is selected depends on the specific firing requirements, the shape of the ceramic products, and the firing effect to be achieved, and it can be flexibly replaced. For example, porous shed plate: The design of small holes can increase air circulation and help the heat distribute more evenly, which is suitable for the firing process that requires good ventilation conditions; non-porous shed plate: The surface has no holes and is relatively flat, mainly used for the firing process that does not require excessive air circulation, or for supporting those ceramic products that cannot directly contact the surface with holes; trough-shaped shed plate: The trough-shaped design can better adapt to some specific-shaped ceramic products. For example, for some long-strip or tubular ceramic parts, the trough-shaped shed plate can provide better support and help reduce deformation.

[0027] Silicon nitride has excellent high-temperature mechanical properties. It can still maintain relatively high strength and toughness at high temperatures and can be used as a stable connecting component in high-temperature environments. Silicon nitride has a low coefficient of thermal expansion, with very small dimensional changes during heating and cooling processes, which helps to maintain the stability of the structure. Silicon nitride has good resistance to most oxidants at high temperatures and is not easily reactive with oxygen in the air. Therefore, it can be used in high-temperature environments for a long time without being corroded. Silicon nitride has a very high hardness and high wear resistance, and can maintain its shape and function even under high-temperature and heavy-load conditions. Compared with some other refractory materials, silicon nitride has a lower density, which can reduce the overall weight of the kiln furniture, helping to reduce energy consumption. Due to its excellent physical and chemical properties, silicon nitride beams can maintain their performance for a long time, thereby extending the service life of the kiln furniture and reducing maintenance costs.

[0028] The toothed struts 2, the transverse silicon nitride beams 4, the longitudinal silicon nitride beams 5, and the inclined silicon nitride beams 6 are hollow inside and have open ends, which helps to reduce the weight of the overall kiln furniture, lower the labor intensity during handling and installation, and also helps to save energy consumption. The cavities formed inside the hollow structure can serve as channels for hot air flow, promoting the flow of hot air between the kiln furniture, helping to improve the heat conduction efficiency and make the temperature in the kiln more uniform. The hollow structure can promote the rapid dissipation of heat by increasing the surface area, reducing the thermal stress caused by temperature differences, which is very important for maintaining the structural integrity of the connecting components and extending the service life. After firing is completed, the hollow structure can accelerate the cooling process, and the hollow part can dissipate heat faster, helping to shorten the production cycle. The hollow structure can improve the ventilation conditions in the kiln, helping to reduce the risk of local overheating in the kiln and further improving the firing quality.

[0029] When the utility model works, the corresponding shelf boards 1, toothed struts 2, strut cap seats 3, transverse silicon nitride beams 4, longitudinal silicon nitride beams 5, and inclined silicon nitride beams 6 are assembled and fixed on the kiln car according to the types, specifications, and quantities of the daily-use porcelain to be fired. Then, the daily-use porcelain to be fired is placed on the shelf board 1. Specifically, one layer of shelf board 1 is installed and one layer of daily-use porcelain is placed, and then the kiln car is pushed into the kiln for firing.

[0030] The utility model is convenient and fast to assemble, has good connection stability, is suitable for use with various types of daily-use porcelain, has a wide application range, high use flexibility, and good economy.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0032] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0033] In the present utility model, unless otherwise clearly specified and defined, the terms "mounted", "connected", "joined", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection, an electrical connection, or communicable with each other; it may be directly connected, or indirectly connected through an intermediate medium, and may be the internal communication of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0034] The above has made an exemplary description of the present utility model in conjunction with the drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as various improvements are made by adopting the method concept and technical solution of the present utility model, or directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
