[0005] Furthermore, the first sealing combination groove is composed of two arc-shaped sealing mating grooves with different cross-sectional dimensions.

[0006] Furthermore, the vertical distance between the left and right sides of the fitting and sealing mating surface is half the thickness from the inner side of the main body assembly connecting groove to the outer side of the main structure of the sand seal groove.

[0007] Furthermore, the installation clearance groove is located at the center of the main structure of the sand seal groove in the vertical direction.

[0008] The beneficial effects of this utility model are: This utility model adopts an integral structure. During installation, the sealing grooves set in multiple positions can work with the sealing strip to achieve a complete and tight connection. The overall installation is more convenient, the overall sealing and isolation after installation is better, and it can ensure better stability of pressure and temperature inside the kiln. The overall safety during use is higher, the durability is stronger, and the disassembly is more convenient and the overall disassembly and assembly cost is lower. Attached Figure Description

[0010] like Figures 1 to 7As shown, a stable tunnel kiln sand sealing groove includes a rectangular sand sealing groove main structure 1. The interior of the sand sealing groove main structure 1 is a hollow main assembly connecting groove 2, which completely penetrates the length of the sand sealing groove main structure 1. The right side of the main assembly connecting groove 2 has an installation clearance groove 3 that penetrates the entire right side, ensuring no interference with other structures during installation. The left side and lower end of the sand sealing groove main structure 1 are respectively provided with integral fastening connection holes 4 communicating with the interior, through which the entire structure is fastened. The upper right end of the installation clearance groove 3 has an inclined fitting and sealing surface 5, ensuring a larger fitting area and initially guaranteeing a seal. The upper and lower sides of the fitting and sealing surface 5 are respectively provided with a first sealing combination groove 6 that penetrates the entire length. The lower outer edge of the right side of the installation clearance groove 3 has a second sealing combination groove 7, enabling multiple sealing fits, resulting in better and more stable sealing after installation. Both the first sealing combination groove 6 and the second sealing combination groove 7 have arc-shaped cross-sections, which facilitates manufacturing and processing. They can also be used with cylindrical sealing strips during installation, improving ease of installation. It adopts a completely new structural design, using an integral structure. During installation, the multiple sealing grooves allow for a comprehensive and tight connection with the sealing strip, making overall installation more convenient. The overall sealing and isolation after installation is better, ensuring better stability of pressure and temperature within the kiln, resulting in higher overall safety and durability during use. Disassembly is also easier and the overall assembly and disassembly costs are lower.

[0011] Preferably, the first sealing combination groove 6 is composed of two arc-shaped sealing mating grooves with different cross-sectional dimensions, which has less impact on the strength of the main structure. Furthermore, when performing sealing mating, it can be used with sealing strips of different sizes, resulting in better sealing stability and complementary sealing effects.

[0012] Preferably, the vertical distance between the left and right sides of the fitting and sealing mating surface 5 is half the thickness from the inner side of the main body combination connecting groove 2 to the outer side of the sand seal groove main structure 1, so that the structural strength at the lower end is higher and the mating stability is better.

[0013] Preferably, the installation clearance groove 3 is located at the center of the sand seal groove main structure 1 in the vertical direction. The load-bearing capacity is stronger when the right side is fitted, and the overall structure is more durable after fitting.

[0014] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements or substitutions can be made without departing from the principle of this utility model, and these improvements or substitutions should also be considered within the protection scope of this utility model.
