Title:
SEALING STRUCTURE OF HORIZONTAL ROTARY PYROLYSIS KILN
Document Type and Number:
WIPO Patent Application WO/2022/068003
Kind Code:
A1
Abstract:
The present invention relates to sealing technologies of thermal sealing covers of horizontal rotary kilns, and provides a sealing structure for a horizontal rotary pyrolysis kiln. A movable heat-insulation sealing ring is disposed such that a heat-insulation cavity is formed between the movable heat-insulation sealing ring and a flexible sealing mechanism. The heat-insulation cavity can effectively block the heat dissipated from a kiln tail cover and a kiln tail, thereby effectively reducing the ambient temperature of the flexible sealing mechanism in the heat-insulation cavity. In this way, the service life of the flexible sealing mechanism is prolonged, and the effectiveness of sealing is thus ensured.
