Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figures 1-4 , the utility model provides an embodiment: a kiln head nozzle sealing device of a kiln, comprising a sliding plate 1, the right outer wall of the sliding plate 1 is fixedly connected to a motor 2, the output end of the motor 2 is fixedly connected to a gear 3, the outer wall of the gear 3 is meshedly connected to a first rack 4, the outer wall of the gear 3 is meshedly connected to a second rack 5, the outer wall of the first rack 4 is slidably connected to a limiting block 6, the right outer wall of the limiting block 6 is fixedly connected to the left outer wall of the sliding plate 1, the lower surface of the first rack 4 is fixedly connected to a driven rod 7, the second rack 5 is slidably connected to the inner wall of the limiting block 6, the upper surface of the second rack 5 is fixedly connected to the lower surface of the driven rod 7, the The upper surface of the moving rod 7 is fixedly connected to the first connecting rod 8, the upper surface of the driven rod 7 is fixedly connected to the second connecting rod 9, the lower surface of the driven rod 7 is fixedly connected to the third connecting rod 10, the lower surface of the third connecting rod 10 is fixedly connected to the heat-insulating splint 11, the outer wall of the heat-insulating splint 11 is slidably connected to the support assembly, and the support assembly is used to support the entire mechanism; the support assembly includes a bracket 12, the outer wall of the bracket 12 is slidably connected to the outer wall of the heat-insulating splint 11, the lower surface of the bracket 12 is fixedly connected to the base 13, the outer wall of the bracket 12 is fixedly connected to the outer wall of the sliding plate 1, and the outer wall of the sliding plate 1 is fixedly connected to the upper surface of the base 13;

[0025] Specifically, the starting motor 2 can drive the gear 3 to rotate, and the gear 3 drives the first rack 4 and the second rack 5 to move, thereby driving the driven rod 7 to slide on the inner wall of the sliding plate 1. The movement of the driven rod 7 drives the first connecting rod 8, the second connecting rod 9 and the third connecting rod 10, and can also drive the insulation splint 11 to move inward, so that the insulation splint 11 clamps the burner body 14.

[0026] Reference Figure 3 and Figure 4 The inner wall of the heat-insulating splint 11 is slidably connected to a nozzle body 14, the outer wall of the nozzle body 14 is slidably connected to a first flange 15, and the outer wall of the first flange 15 is fixedly connected to a connecting ring 16; the inner wall of the connecting ring 16 is provided with a sealed groove 17, the inner wall of the sealed groove 17 is slidably connected to a positioning ring 18, and the inner wall of the positioning ring 18 is fixedly connected to a positioning block 19; the outer wall of the positioning ring 18 is fixedly connected to a spring sheet 20, the upper surface of the spring sheet 20 is fixedly connected to a spring body 22, and the inner wall of the spring body 22 is fixedly connected to a pressing rod 21;

[0027] Specifically, the first flange 15 drives the connecting ring 16 so that the positioning ring 18 in the sealed groove 17 on its inner wall can slide on the outer wall of the sealing ring 23. When the positioning block 19 is stuck in the limiting groove 24 on the inner wall of the sealing ring 23, the spring sheet 20 can be deformed, thereby driving the spring body 22 and the downward pressure rod 21 to move downward. The sealing ring 23 drives the second flange 25 to move and is connected to the first flange 15 by bolts 26, thereby connecting the connecting pipe 27 and the burner body 14.

[0028] Reference Figure 3 and Figure 4 The outer wall of the lower pressure rod 21 is slidably connected to the inner wall of the connecting ring 16, and the inner wall of the connecting ring 16 is slidably connected with a sealing ring 23, and the inner wall of the sealing ring 23 is provided with a limiting groove 24; the inner wall of the limiting groove 24 is slidably connected to the outer wall of the positioning block 19, and the outer wall of the sealing ring 23 is fixedly connected to the second flange 25, and the inner wall of the second flange 25 is rotatably connected to the bolt 26, and the outer wall of the bolt 26 is rotatably connected to the inner wall of the first flange 15; the inner wall of the second flange 25 is slidably connected to the connecting pipe 27, and the outer wall of the connecting pipe 27 is fixedly connected to the kiln head body 28, and the outer wall of the kiln head body 28 is fixedly connected to the outer wall of the base 13;

[0029] Specifically, by pressing the down-press rod 21 downward, the spring body 22 is driven so that the spring sheet 20 pushes the positioning ring 18 to move outward, and then the first flange 15 and the second flange 25 are separated by rotating the bolt 26. Moving the second flange 25 drives the sealing ring 23 to move, so that the connecting pipe 27 and the nozzle body 14 are separated, and the nozzle body 14 can be quickly disassembled and assembled.

[0030] Working principle: When the device needs to be used, the motor 2 is started to drive the gear 3 to rotate, and the gear 3 rotates the first rack 4 and the second rack 5 to move and drive the driven rod 7 to slide on the inner wall of the sliding plate 1. The driven rod 7 moves and drives the first connecting rod 8, the second connecting rod 9 and the third connecting rod 10 to move the heat insulation clamping plate 11 inward, so that the heat insulation clamping plate 11 clamps the burner body 14. When the burner body 14 needs to be replaced, the motor 2 is reversed to drive the gear 3, the first rack 4, the second rack 5, and the third rack 7 to move inward. The rack 5, the driven rod 7 and the like move in the opposite direction, thereby causing the heat-insulating splint 11 to loosen the nozzle body 14. After the nozzle body 14 is clamped, the first flange 15 on its outer wall drives the connecting ring 16, causing the positioning ring 18 in the sealed groove 17 on its inner wall to slide on the outer wall of the sealing ring 23. When the positioning block 19 is engaged with the limiting groove 24 on the inner wall of the sealing ring 23, the spring sheet 20 is deformed, driving the spring body 22 and the lower pressure rod 21 to move downward, and the sealing ring 23 drives the second flange 25 to move and connects with the first flange 25. The flange 15 is connected by bolts 26 so that the connecting pipe 27 and the nozzle body 14 are connected through the device. When the nozzle body 14 is replaced, the lower pressure rod 21 is pressed downward to drive the spring body 22 to make the spring sheet 20 push the positioning ring 18 outward, and then the bolt 26 is turned to separate the first flange 15 and the second flange 25. Moving the second flange 25 drives the sealing ring 23 to move, so that the connecting pipe 27 and the nozzle body 14 are separated, and the nozzle body 14 can be quickly disassembled and assembled. This device not only solves the problem that the traditional fixing method may not be able to effectively clamp the nozzle body 14, and the high temperature generated during the operation of the nozzle body 14 is likely to cause safety hazards to surrounding equipment and operators, causing the nozzle body 14 to loosen or displace during operation, thereby affecting production efficiency and quality. At the same time, it also solves the problem that traditional sealing methods such as gaskets or sealants are easily affected by high temperature, high pressure, corrosion and other factors during long-term use, resulting in reduced sealing performance and leakage.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
