[0026] like Figure 1 and Figure 2 As shown, the present application provides a kiln door sealing structure, including a group of door bodies 2 arranged at the kiln mouth of the kiln head 1 and abutting against the kiln mouth of the kiln head 1, a semicircular arc opening is respectively provided in the middle of one side adjacent to the two door bodies 2, and the two semicircular arc openings form an installation opening 3, a connecting flange 4 is provided at the installation opening 3, and a plurality of fish scale sealing sheets 5 arranged staggered with each other are provided on the outer periphery of the connecting flange 4, and a plurality of fish scale sealing sheets 5 form a conical sealing opening on the side away from the installation opening 3, and the connecting flange 4 is connected to a coal injection pipe 6, and rock wool 7 is filled between the four sides of the coal injection pipe 6 and the fish scale sealing sheet 5. Specifically, one end of the fish scale sealing sheet 5 is fixedly connected to the connecting flange 4, and a wire groove is provided on the end of the fish scale sealing sheet 5 away from the connecting flange 4. By using the cooperation of the steel wire rope and the wire groove, the plurality of fish scale sealing sheets can be connected 5 is tied tightly to the outer wall close to the coal injection pipe 6, and the gaps between the two door bodies 2 and between the two door bodies 2 and the kiln mouth of the kiln head 1 are filled with casting material 8. The outer sides of the two door bodies 2 are provided with a sealing component 9 and two extrusion components 10. The two extrusion components 10 cooperate with the sealing component 9 to lock the two door bodies 2 at the kiln mouth of the kiln head 1. The coal injection pipe 6 and the connecting flange 4 are sealed by the cooperation of rock wool 7 and fish scale sealing sheet 5, and the door gap is sealed by the casting material. Then, the door body 2 is locked and further sealed by the cooperation of the extrusion component 10 and the sealing component 9, which has a good sealing effect, effectively solves the problem that the kiln door is not well sealed and easy to leak clinker powder, avoids kiln door leakage, increases the workload of daily sanitation cleaning of the kiln head 1 platform, and reduces the risk of scalding.

[0027] like Figure 1 and Figure 2 As shown, the sealing assembly 9 includes a sealing plate 91 and a sealing material layer 92. A through hole is provided in the middle of the sealing plate 91. The sealing plate 91 is sleeved on the outer periphery of multiple fish-scale sealing sheets 5 through the through hole. The sealing material layer 92 is located between the sealing plate 91 and the two door bodies 2. The sealing material layer 92 is fixed on the sealing plate 91. When the sealing assembly 9 is squeezed by the extrusion assembly 10, the sealing plate 91 squeezes the sealing material layer 92, so that the sealing material layer 92 is pressed against the two door panels, so that the gap between the two door panels can be sealed at the same time.

[0028] like Figure 2 As shown, the sealing material layer 92 is made of graphite packing, which is wear-resistant and high-temperature resistant. Graphite packing can extend the service life of the sealing material layer 92 by serving as the sealing material layer 92 .

[0029] like Figure 1 and Figure 2As shown, the size of the sealing plate 91 is larger than the size of the kiln head 1 and the kiln opening, and the size of the sealing material layer 92 is consistent with the size of the sealing plate 91. The sealing plate 91 and the sealing material layer 92 can cover the kiln head 1 and the kiln opening, further sealing the gap between the two door bodies 2 and between the two door bodies 2 and the kiln head 1 and the kiln opening, thereby improving the sealing effect.

[0030] like Figure 1 and Figure 2 As shown, the two extrusion components 10 are symmetrically arranged, and the extrusion components 10 include a connecting seat 101, a connecting piece 102 and a locking bolt 103. The connecting seat 101 is fixed on the kiln head 1, and the connecting piece 102 is hinged to the connecting seat 101. The connecting piece 102 is provided with a threaded through hole, and the locking bolt 103 is threadedly connected to the connecting piece 102 through the threaded through hole. The lower end of the locking bolt 103 abuts against the sealing plate 91, and the connecting piece 102 is rotated so that the threaded through hole of the connecting piece 102 is located above the sealing plate 91. The locking bolt 103 is screwed into the threaded through hole, and the lower end of the locking bolt 103 is pressed against the sealing plate 91. Through the arrangement of the two extrusion components 10, the sealing plate 91 is extruded, so that the sealing plate 91 squeezes the sealing material layer 92, and then squeezes the two door bodies 2, so that the door bodies 2 are pressed against the kiln mouth of the kiln head 1.

[0031] like Figure 1 and Figure 2 As shown, a positioning member 11 is provided on the connecting seat 101. When the connecting member 102 is rotated to abut against the positioning member 11, the threaded through hole is perpendicular to the sealing plate 91. The setting of the positioning member 11 facilitates the positioning of the threaded through hole.

[0032] like Figure 2 As shown, the outer sides of the two door bodies 2 are provided with pry holes 12, and the door bodies 2 can be pried up with a crowbar. Specifically, when it is necessary to open the kiln head 1, the locking bolt 103 on the extrusion assembly 10 is rotated to loosen the abutment of the locking bolt 103 on the sealing plate 91, and the sealing plate 91 is moved upward so that the sealing plate 91 and the sealing material layer 92 are away from the two door bodies 2, and then the door bodies 2 can be pried up with a crowbar.

[0033] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
