Abstract
The invention discloses a sealing device for a kiln head of a rotary granulation kiln. The sealing device for the kiln head of the rotary granulation kiln comprises a sealing disc and a fixing support of the sealing disc, wherein the sealing disc is used for sealing an inlet of the kiln head. The sealing disc is provided with a pipe body which is matched with the circumferential surface of the inner side of an annular pipe at the inlet of the kiln head. A labyrinth sealing mechanism is arranged inside the kiln head. A flexible end face sealing mechanism is arranged outside the kiln head. The flexible end face sealing mechanism comprises a dynamic sealing gasket and a static sealing gasket, wherein the dynamic sealing gasket and the static sealing gasket are made of flexible materials. The dynamic sealing gasket is fixed to the outer wall of the portion, around the inlet of the kiln head, of the kiln head. The static sealing gasket is fixed to a movable support. The movable support is movably fixed to a pipe body of the sealing disc in the axial direction of the pipe body of the sealing disc through an elastic device. Through the arrangement of the labyrinth sealing mechanism and the flexible sealing mechanism, the sealing effect can be improved, and the sealing device can be adapted to the working environment in which a kiln body expands due to heat, contracts due to cold and moves in the radial direction and the axial direction, the high-temperature working environment, the high-dust-content working environment and other severe working environments.
