Description

Technical Field

[0001] This utility model relates to a water-cooled shaft for a chain grate machine, and more particularly to a waterproof vapor spray device for the water-cooled shaft of a chain grate machine. Technical Background

[0002] During the production process of the chain grate machine, the water-cooled shaft is constantly rotating. Since the temperature of the water-cooled shaft reaches 800~1050℃, it is always in a high-temperature region. Therefore, cooling water is needed to cool the water-cooled shaft and prevent it from deforming under heat during load. The water-cooled shaft is a hollow shaft, and the cooling water pipe is inserted into the through hole in the shaft center. Cooling water flows from one end of the shaft to the other, achieving the purpose of cooling and lowering the temperature. When the cooling water is heated, it produces water vapor. This water vapor expands in volume within the shaft center and moves rapidly towards both ends of the shaft. The water vapor splashes out the moment it leaves the shaft head, causing cooling water loss. Utility Model Content

The shaft ends at both ends of the water-cooled shaft extend out of the side plates 1, pass through the water-cooled shaft bearing seats 3 and the internal bearings, and are rotatably connected to the bearings. The cooling water inlet pipes 4 are located on the outer sides of both ends of the water-cooled shaft. Two cooling water return pipes 5 are respectively located on the lower outer sides of the two water-cooled bearing seats 3. The cooling water inlet pipes 4 are inserted into the hollow shaft of the water-cooled shaft 2. The feature is that a waterproof vapor spraying device 6 is installed at each end of the water-cooled shaft of the chain grate machine. The waterproof vapor spraying device 6 is a split structure, including an upper cover 61, an upper box 62, a lower box 63, a flared tube sleeve A64, and a flared tube sleeve B65. The upper cover 61 is hinged to the upper box 62 by a hinge 612, and a handle 611 is also provided on the upper cover 61. The upper box 62 is a square upper box without a bottom, and a downwardly recessed semi-circular groove 621 is opened at the middle of the lower edge of both the front and rear ends of the upper box 62. The lower box 63 is also a square lower box without a bottom, and a downwardly recessed semi-circular groove 621 is opened at the middle of the upper edge of both the front and rear ends of the lower box 63. The upper recessed semi-circular groove 631 has an arc surface 633 on the lower part of both sides of the left and right edges of the lower housing 63. An inlet 51 matching the size of the arc surface of the lower housing is opened on the upper part of the cooling water return pipe 5.
