Compared with the overall Yankee hood, the width or height is reduced, which is convenient for transportation. At the same time, the upper and lower parts of the structure are prefabricated, so there is no need to worry about the loosening and falling of parts during transportation, and transportation is safer.
[0028] Secondly, the present application arranges connecting parts at the joints of the side panels and the crescent heads respectively, increases the contact surface of the upper and lower side panels at the edges, and increases the contact surface of the upper and lower crescent heads at the edges, thereby improving the stability of the Yankee gas hood during splicing without interfering with the original structure of the Yankee gas hood.
[0029] In a specific embodiment, the side panel upper connecting member 113 includes a side panel connecting plate 1131, which is perpendicular to the upper part 111 of the side panel, and its lower surface is aligned with the lower edge of the upper part 111 of the side panel; the side panel lower connecting member 123 includes a side panel lower connecting plate 1231, which is perpendicular to the side panel lower part 121, and its upper surface is aligned with the upper edge of the side panel lower part 121; the lower surface of the side panel connecting plate 1131 is in contact with the upper surface of the side panel lower connecting plate 1231 and is fixed to each other by bolts.
[0030] Specifically, the Yankee hood side panels are respectively located on the left and right sides of the Yankee hood body 100, and the Yankee hood side panels are arranged in the front-to-back direction, and each Yankee hood side panel is divided into an upper side panel 111 and a lower side panel 121; the upper connecting plate 1131 of the side panel is arranged in the horizontal direction and perpendicular to the upper side panel 111, and the bottoms of the two are aligned; the lower connecting plate 1141 of the side panel is arranged in the horizontal direction and perpendicular to the lower side panel 121, and the tops of the two are aligned; when the Yankee hood body 100 is spliced, the connecting plate 1131 of the side panel and the lower connecting plate 1141 of the side panel increase the contact area between the upper side panel 111 and the lower side panel 121, and provide a mounting carrier without bolts, so that the upper side panel 111 and the lower side panel 121 fixed to each other by bolts are more stable.
[0031] In order to improve the connection stability between the upper part 111 of the side panel and the lower part 121 of the side panel, a plurality of through holes are respectively provided at intervals along the front-to-rear direction on the upper connecting plate 1131 of the side panel and the lower connecting plate 1231 of the side panel, so that the number of bolts installed between the upper connecting plate 1131 of the side panel and the lower connecting plate 1231 of the side panel is increased.
