Abstract
Provided is 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.
Claims8
A sealing structure of a horizontal rotary pyrolysis kiln, wherein the sealing structure of a horizontal rotary pyrolysis kiln is provided between a kiln tail cover and a kiln tail, and comprises:
- a support frame fixedly connected to a periphery of the kiln tail, wherein the support frame is provided with a rotary sealing mechanism in rotary sealing contact with the support frame;
- the rotary sealing mechanism comprises:
- a plurality of evenly distributed shifting forks;
- a support seat rotatably connected with the support frame;
- a first limiting fitting part with one end fixed to a periphery of the kiln tail cover;
- and a movable heat-insulation sealing ring and a flexible sealing mechanism connected between the support seat and the first limiting fitting part;
- each of the shifting forks is spatially located on an outer side of the flexible sealing mechanism, one end of each of the shifting forks is fixedly connected with the first limiting fitting part on the periphery of the kiln tail cover, and the other end of each of the shifting forks is movably connected to the support seat;
- and the movable heat-insulation sealing ring is spatially located on an inner side of the flexible sealing mechanism;
- and
- one end of the movable heat-insulation sealing ring is fixedly connected with the support seat, and the other end of the movable heat-insulation sealing ring is movably connected with the first limiting fitting part, such that a heat-insulation cavity is formed between the movable heat-insulation sealing ring and the flexible sealing mechanism,
- wherein the support seat comprises a second limiting fitting part configured to be connected with the shifting forks, the flexible sealing mechanism and the movable heat-insulation sealing ring, respectively;
- the second limiting fitting part is annular,
- wherein the second limiting fitting part is provided with a gas loading pipeline, and the gas loading pipeline is communicated with the heat-insulation cavity to load a gas medium.
