Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present invention.

As shown in fig. 1 to 8, the sealing door device for the atmosphere kiln according to the embodiment of the utility model includes a sealing door frame 2, a passage opening 10 is reserved at the lower part of the sealing door frame 2, an air cylinder 9 is arranged above the sealing door frame 2, a push-pull plate 3 is arranged inside the sealing door frame 2, the push-pull plate 3 is connected to the lower end of the air cylinder 9 through an air cylinder push rod 1, a sealing door 5 is arranged outside the push-pull plate 3, the sealing door 5 includes a first sealing door 51 and a second sealing door 52 which are located at two sides of the push-pull plate 3, waist-shaped holes 8 are arranged at the upper part and the lower part of the first sealing door 51 and the second sealing door 52, and the waist-shaped holes 8 and the push-pull plate 3 are connected through a push-pull shaft 4; a limiting block 6 is arranged below the push-pull plate 3; a roller 7 is arranged below the sealing door 5; a cutting hole is reserved in the middle of the push-pull plate 3; the upper parts of the waist-shaped holes 8 are inclined towards the outer side of the sealing door 5.

In order to facilitate understanding of the above-described technical aspects of the present invention, the above-described technical aspects of the present invention will be described in detail below in terms of specific usage.

When the channel opening 10 needs to be opened in specific use, the air cylinder 9 contracts the air cylinder push rod 1 upwards, the air cylinder push rod 1 drives the push-pull plate 3 to move upwards, the push-pull plate 3 drives the push-pull shaft 4 to move upwards, the waist-shaped hole 8 and the vertical direction form a certain included angle, when the push-pull shaft 4 moves from the lower end of the waist-shaped hole 8 to the upper end of the waist-shaped hole 8, the sealing door 5 can move transversely along the roller 7, so that the distance between the first sealing door 51 and the second sealing door 52 is shortened (see fig. 7), a sealing ring of the sealing door 5 is separated from the sealing door frame 2, when the push-pull shaft 4 moves to the upper end of the waist-shaped hole 8 and then continues to ascend to the top of the sealing door frame 2 along with the push-pull shaft 4, and the channel opening 10 is opened at the moment; when the passage opening 10 needs to be closed, the air cylinder 9 pushes the air cylinder push rod 1 downwards, the air cylinder push rod 1 drives the push-pull plate 3 to move downwards, the push-pull plate 3 drives the push-pull shaft 4 to move downwards, the push-pull shaft 4 is positioned at the upper end of the waist-shaped hole 8 when beginning to descend, the sealing door 5 cannot continue to descend after the sealing door 5 contacts the roller 7, but the push-pull shaft 4 can continue to descend in the waist-shaped hole 8 of the sealing door 5, because the waist-shaped hole 8 and the vertical direction have a certain included angle, when the push-pull shaft 4 moves from the upper end of the waist-shaped hole 8 to the lower end of the waist-shaped hole 8, the sealing door 5 can transversely move along the roller 7, so that the distance between the first sealing door 51 and the second sealing door 52 is opened (see fig. 8), the sealing door 5 gradually approaches the sealing door frame 2, when the lower bottom surface of the push-pull plate 3 contacts the limiting block 6, the air cylinder 9 stops moving, and the sealing ring on the sealing door 5 is pressed on the sealing door frame 2, the passage opening 10 is closed tightly; the middle cut hole of the push-pull plate 3 is used for reducing the weight of the push-pull plate 3; the limiting block 6 can limit the maximum distance of downward movement of the push-pull plate 3, and the limiting block 6 can be made of polyurethane materials.

In conclusion, by means of the technical scheme, the problems that the traditional sealing door is complex in structure, high in failure rate, difficult to maintain and the like can be solved, and the device is simpler in structure, higher in reliability and more convenient and faster to operate.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
