[0002] In the field of kiln technology, especially in large push plate type natural gas kiln, the sintering process of ceramic products is extremely strict. The traditional internal structure of the kiln usually uses silicon carbide plates as the main component of the rack for carrying and conveying the ceramic products to be sintered. However, in the actual application process, there are often some problems in the connection and assembly between these silicon carbide plates.

[0003] Specifically, due to the assembly gap at the joint between the silicon carbide plates, these gaps are prone to become channels for flame leakage during high-temperature sintering. The leakage of flame not only affects the uniformity of temperature distribution in the kiln, but also may cause local temperature to be too high or too low, thereby adversely affecting the sintering quality of the ceramic products. Especially for corundum grinding wheels and other ceramic products that need to strictly control the sintering temperature, the inconsistency of temperature may cause quality problems such as cracks and deformation in the products.

Narrow cover plates 3 are provided around the entire structure after the base plates 1 are spliced ​​together. Through clever design, the sequential splicing of the base plates 1 is achieved, and the step 11 is installed at the top center of the base plate 1, with cover plate slots 13 provided between the steps 11. This structural design allows the base plates 1 to be tightly covered by the wide cover plates 2, effectively concealing the gaps at the splicing points. At the same time, square cover plates 4 are also provided between the ends of the wide cover plates 2, further enhancing the sealing and stability of the structure. In addition, the narrow cover plates 3 are provided around the entire structure after the base plates 1 are spliced ​​together, ensuring the integrity and aesthetics of the entire silicon carbide plate structure. This series of designs not only improves the sealing performance of the kiln and prevents flame leakage, but also enhances the overall stability of the structure, providing a more uniform and stable temperature environment for the sintering process of ceramic products.

[0027] In this embodiment, a fire-blocking upright plate 5 is installed on the outer side of the narrow cover plate 3. The fire-blocking upright plate 5 effectively prevents the flame from directly irradiating the outside of the kiln or damaging the internal structure of the kiln, while enhancing the sealing and heat preservation performance of the kiln and improving the stability and efficiency of the sintering process.

[0028] Specifically, a plug 51 is installed at the bottom of the fire baffle plate 5, and a slot 15 is provided at the top of the base plate 1 near the plug 51. The plug 51 and the slot 15 are inserted into each other. Through the insertion and engagement of the plug 51 and the slot 15, a firm connection is achieved between the fire baffle plate 5 and the base plate 1, which enhances the overall stability and thermal shock resistance of the structure and ensures the stable operation of the kiln under long-term high temperature.

[0029] Furthermore, the steps 11 are provided with cover plate limiting grooves 12 around their perimeter, and first locking blocks 21 are installed on both sides of the bottom of the wide cover plate 2, which engage with the cover plate limiting grooves 12.

Square cover plates 4 are placed between the ends of the wide cover plates 2, further enhancing the sealing and stability of the structure.

[0035] After the base plate 1 is assembled, narrow cover plates 3 are installed around the entire structure to ensure the integrity and aesthetics of the entire silicon carbide plate structure. Fire baffle plates 5 are installed on the outside of the narrow cover plates 3 to effectively prevent flames from directly shining on the outside of the kiln or damaging the internal structure of the kiln, while also enhancing the kiln's sealing and heat preservation performance.

[0036] A plug 51 is installed at the bottom of the fire-resistant upright plate 5, and a slot 15 is provided at the top of the base plate 1 near the plug 51. Through the plug-in cooperation between the plug 51 and the slot 15, a firm connection is achieved between the fire-resistant upright plate 5 and the base plate 1, which enhances the overall stability and thermal shock resistance of the structure.

[0037] Cover plate limiting grooves 12 are made around the perimeter of step 11. First locking blocks 21 are installed on both sides of the bottom of the wide cover plate 2, engaging with the cover plate limiting grooves 12 to securely install the wide cover plate 2 onto the base plate 1, effectively preventing displacement or detachment of the cover plate under high temperatures. A second locking block 31 is installed on one bottom side of the narrow cover plate 3, engaging with the cover plate limiting grooves 12 to ensure the narrow cover plate 3 fits tightly against the perimeter of the base plate 1.

[0038] A dovetail groove 14 is obliquely provided at the bottom of the base plate 1, which improves the installation firmness and anti-slip performance of the base plate 1, ensuring the stability and reliability of the base plate 1 during kiln operation. Refractory coating is filled into the gap between the cover plate limiting groove 12 and the cover plate, effectively sealing the gap, improving the kiln's sealing and refractory performance, and preventing leakage of flames and high-temperature gases. The base plate 1 is made of silicon carbide, which has excellent high-temperature resistance and thermal shock resistance. Under prolonged high-temperature conditions, the base plate 1 remains stable, extending the kiln's service life and improving sintering efficiency and quality.
