Example 1, see FIGS. 1-6:

the embodiment provides a novel kiln door sealing device, which comprises a kiln door and a sealing assembly. The kiln door comprises a pair of door bodies 1 which are hinged in a split mode, the door bodies 1 are installed on a kiln head, semicircular installation openings 4 are formed in the centers of the two door bodies 1 respectively, and the installation openings 4 are used for inserting coal injection pipes. For the door body 1 in the scheme, the door body 1 is hinged to realize split opening, wherein the attached drawings show that a first hinged seat 11 is fixedly arranged on the door body 1, a second hinged seat 12 is arranged on a wall body, and the first hinged seat 11 and the second hinged seat 12 are hinged through a connecting plate 13. Meanwhile, the first hinged seat 11 and the second hinged seat 12 have two door shafts, and the door shafts are far away from the door body 1 and are less affected by temperature. Meanwhile, a plurality of lock catches 5 are arranged on the periphery of the door body 1 and used for locking the door body 1 after the door body 1 is closed, which is the same as the prior art.

And the mounting openings 4 are respectively provided with a connecting flange 3, and the connecting flanges 3 are semicircular and annular and can be separated and butted. The sealing assembly needs to be matched with the connecting flange 3 for installation, and specifically comprises a pair of flange seats 2 with the same structure and a plurality of fish scale sealing pieces 6. The flange seat 2 has a semi-cone cylindrical structure and is reduced in the direction away from the door body 1. The two flange seats 2 are respectively installed on the two door bodies 1 and fixed with the connecting flange 3, so that butt joint and separation can be carried out. Meanwhile, the upper end of the flange seat 2 on the left side and the lower end of the flange seat 2 on the right side are both hinged with an arc-shaped turning plate 7. The arc-shaped turning plate 7 is used for turning over towards the outer side of the flange seat 2, certain redundancy can be reserved for the scale sealing pieces 6 through the arc-shaped turning plate 7, and the scale sealing pieces 6 can be conveniently overlapped and sealed. Simultaneously, the free end of arc turns over board 7 is equipped with kink 8 for arc turns over board 7 wholly to present the S type and buckles, so after two flange seat 2 docks, can see out with the attached drawing, this kink 8 can be followed the periphery of another flange seat 2 and wrapped, can strengthen sealedly to the junction of two flange seats 2 like this.

The fish scale sealing sheet 6 is used for installing the periphery of flange seat 2 and overlap setting each other, can see out with the attached drawing, and fish scale sealing sheet 6 turns over board 7 fixedly through welding and arc through bolt and nut and flange seat 2 is fixed, turns over after 2 closure of flange seats the fish scale sealing sheet 6 and constitutes the seal opening of awl tube-shape, just so can seal the coal injection pipe. The fish scale sealing sheet 6 adopts a following mode, so that the fish scale sealing sheet can adapt to the movement characteristics of the split type kiln doors and is not required to be frequently disassembled, and the common opening method cannot be suitable. However, in this embodiment, the arc-shaped turning plate 7 leaves a certain turning angle for the fish scale sealing plate 6, so that the conical opening can be closed.

The outer sides of the scale sealing sheets 6 are provided with steel wire rope fixing seats 9, and the outer sides of the scale sealing sheets 6 fixedly covered on the bending parts 8 or the arc turning plates 7 are provided with the steel wire rope fixing seats 9. The steel wire rope fixing seat 9 is a seat plate fixedly arranged on the scale sealing sheet 6, the length of the steel wire rope fixing seat needs to cover the scale sealing sheet 6, a perforation part 10 used for penetrating a steel wire rope is arranged on the steel wire rope fixing seat 9, and the perforation part 10 is designed to be an opening for facilitating rope drawing. The steel wire rope can tighten the fish scale sealing sheet 6 to realize sealing by matching with a load, and convenience is provided for opening the arc-shaped turning plate 7 through the perforation part 10.

When the device is used specifically, the use method of the device is the same as that of a common split kiln door, but when the door body 1 is opened, the steel wire rope fixing seat 9 needs to be pulled to pull the arc-shaped turning plate 7 outwards, the arc-shaped turning plate 7 drives the overlapped fish scale sealing pieces 6 to be unfolded, so that the cone opening is expanded, and meanwhile, the interference between the two flange seats 2 is also eliminated, so that the two flange seats are completely separated. The sealing assembly can then be opened with the door body 1 in a split manner to achieve complete opening of the kiln door.

The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
