Embodiment 1

[0026] Embodiment one, see figure 1 , a chimney cover, including a door panel 2 and a driving mechanism 3 for covering a chimney 1.

[0027] There are two pairs of door panels 2. The four door panels in the two pairs of door panels 2 are distributed as a left outer door panel 2-1, a left inner door panel 2-2, a right inner door panel 2-3 and a right inner door panel 2-3. The left outer door panel 2-1 and the left inner door panel 2-2 form a pair and are oppositely opened. The right inner door panel 2-3 and the right inner door panel 2-3 constitute a pair and are oppositely opened. The door panel 2 is provided with a rotating shaft 4 , specifically, the left outer door panel 2 - 1 is provided with a fourth rotating shaft 44 . The left inner door panel 2-2 is provided with a third rotating shaft 43 . The right inner door panel 2-3 is provided with a second rotating shaft 42 . The right inner door panel 2-3 is provided with a first rotating shaft 41 . The first rotating sha...

Abstract

The present invention relates to chimney covers. A chimney baffle door structure with small leakage, good drainage effect and good stability when kept in an open and closed state, comprises a door panel and a driving mechanism. A lower sealing seat is provided at the butt joint of two door panels of the same pair of door panels, and an upper sealing seat is provided at the butt joint of the door panel and the chimney, as well as the butt joint of the adjacent door panels between the two pairs of door panels, and the upper surface of the lower sealing seat is provided with an upper sealing seat. There is a drainage groove that communicates with the outside of the chimney. The door plate is provided with a cavity along the radial direction of the rotating shaft, which extends beyond the rotating shaft. The cavity is provided with buffer springs at both ends along the radial direction of the rotating shaft. The balance block is in contact with the buffer spring at the corresponding end when it is opened or closed. The invention solves the problems that the chimney baffle door has a large leakage rate, poor drainage effect and is not easy to keep in an open state.

Description

technical field [0001] The invention relates to a chimney, in particular to a chimney cover. Background technique [0002] One of the components in the waste heat utilization flue gas main chimney system is the chimney cover. When the waste heat boiler is running, the chimney cover is opened, and the chimney tail gas is discharged to the atmosphere through the main chimney; when the waste heat boiler is not running, the chimney cover can be closed, which is very convenient. Greatly reduce the temperature drop in the waste heat boiler, provide greater energy for the waste heat boiler to start again, and reduce the heating time of the waste heat boiler. The structure of the existing chimney cover is 2009203013416, the authorized announcement date is January 13, 2010, and the name is disclosed in the patent document of "main chimney door panel" as Chinese patent number 2009203013416. The two door panels drive the door panels to rotate through connecting rods. The existing chi...
