Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sealing devices, in particular to a new type grate cooler sealing device. Background Art
[0002] Grate cooler is an important equipment in the clinker burning system of cement plant. The main function of grate cooler is to cool and transport cement clinker. At the same time, grate cooler also provides hot air for rotary kiln and decomposition furnace. At present, the closed air chamber partitions at the bottom of the fixed module and the movable module of the common grate cooler will be penetrated by moving parts. Since the moving parts will make reciprocating motion during the operation of the grate cooler, the moving parts will rub against the partitions of the closed air chamber for a long time. When the partitions are severely worn, the sealing between them and the moving parts is reduced, which leads to serious air leakage between the two closed air chambers and poor cooling effect of the upper high-temperature clinker. Therefore, a new grate cooler sealing device is proposed. Utility Model Content
[0003] The purpose of the present utility model is to solve any one of the problems in the above-mentioned technologies, and thus proposes a new type of grate cooler sealing device, including a partition and a moving part arranged in the middle of the partition, a sealing cover is installed on the partition, a cover plate is installed on the top of the sealing cover, bolts are symmetrically provided on both sides of the sealing cover, supports are symmetrically provided on the top of the cover plate, a protruding rod is connected to one side of the support, and a tension spring is provided between the bolt and the protruding rod for connection.
[0004] Furthermore, the sealing cover and the partition are fixed by a welding process. After the welding between the partition and the sealing cover is completed, the connection between the partition and the sealing cover can form a seal.
[0005] Furthermore, two first connecting seats are symmetrically provided on one side of the top of the sealing cover, and a second connecting seat is provided on one side of the top of the cover plate.
[0006] Furthermore, the first connecting seat and the second connecting seat are hinged, and the cover plate can rotate around the first connecting seat.
[0007] Furthermore, a torsion spring is provided at the connection between the first connecting seat and the second connecting seat.
[0008] Beneficial effects: The utility model installs a sealing cover on the head of the moving part. The sealing cover has a certain height to meet the reciprocating stroke of the moving part. At the same time, the sealing cover is welded and fixed to the partition, so that there is no air leakage between the sealing cover and the partition. The partition and the moving part are further sealed by the sealing cover. At the same time, the sealing cover is simple to manufacture and easy to install, which effectively reduces the air leakage problem between the air chambers. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0015] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.
[0016] Below, the new grate cooler sealing device according to the embodiment of the present invention is described with reference to the accompanying drawings. Figures 1 to 3 As shown, the new grate cooler sealing device includes a partition 1 and a moving part 2 arranged in the middle of the partition 1, a sealing cover 3 is installed on the partition 1, a cover plate 4 is installed on the top of the sealing cover 3, bolts 301 are symmetrically provided on both sides of the sealing cover 3, and supports 401 are symmetrically provided on the top of the cover plate 4. A protruding rod 402 is connected to one side of the support 401, and a tension spring 5 is provided between the bolt 301 and the protruding rod 402 for connection.
[0017] Preferably, the sealing cover 3 and the partition 1 are fixed by a welding process. After the welding between the partition 1 and the sealing cover 3 is completed, the connection between the partition 1 and the sealing cover 3 can form a seal. The sealing cover 3 has a certain height to meet the reciprocating stroke of the moving part 2.
[0018] Preferably, two first connecting seats 302 are symmetrically provided on one side of the top of the sealing cover 3 , and a second connecting seat 403 is provided on one side of the top of the cover plate 4 .
[0019] Preferably, the first connecting seat 302 and the second connecting seat 403 are hinged, and the cover plate 4 can rotate around the first connecting seat 302 .
[0020] Preferably, a torsion spring 6 is provided at the connection between the first connecting seat 302 and the second connecting seat 403. When the cover plate 4 is not subjected to external force, the cover plate 4 will fit tightly with the top of the sealing cover 3 through the setting of the torsion spring 6, thereby improving the sealing between the cover plate 4 and the sealing cover 3.
[0021] In a specific embodiment: by arranging two tension springs 5 between the sealing cover 3 and the cover plate 4, the cover plate 4 will fit tightly with the top of the sealing cover 3 when not subject to external force, thereby improving the sealing between the cover plate 4 and the sealing cover 3; when the moving part 2 has a problem and hits the cover plate 4, since the cover plate 4 and the sealing cover 3 are hinged through the first connecting seat 302 and the second connecting seat 403, the cover plate 4 will rotate outward when hit by the moving part 2, thereby avoiding damage to the cover plate 4 after being hit by the moving part 2; when the moving part 2 returns to its position, the cover plate 4 will automatically return to its original position under the action of the tension spring 5 and the torsion spring 6.
