Abstract

The invention relates to a novel high-temperature sealing device. The novel high-temperature sealing device comprises sealing boxes (1), hard antifriction lubricating materials (2), spring guide pipes (3), springs (4) and pressing plates (5); each sealing box comprises a side wall (1-1) and a bottom wall (1-2) and the side wall and the bottom wall form a cavity (1-3); the hard antifriction lubricating materials, the spring guide pipes, the springs, and the pressing plates are all arranged in the cavity; the bottom wall is connected with the spring guide pipes, one end of each spring is fixed on the bottom wall and is positioned in the spring guide pipe, and the other end of each spring is contacted with the pressing plate; each pressing plate is provided with a groove (5-1), the hard antifriction lubricating materials are arranged on the groove, and are directly contacted with movement pieces (6); a gap is reserved between the pressing plate and the side wall; and the side wall is provided with an air port (1-4).

Description

technical field [0001] The invention relates to a novel high-temperature sealing device, in particular to a sealing device for a material pushing device at the front end of a grate cooler. Background technique [0002] The moving parts in high temperature environment put forward great requirements on the sealing device between the outside world and the high temperature area. Not only is the sealing effect good, but the sealing device has a long life, and it is also required to prevent the particles in the high temperature area from spraying out, posing a threat to people and equipment. For example, the commonly used pushing device at the front end of the grate cooler is mainly used to destroy the "snowman" accumulated inside the grate cooler. The harsh working conditions inside the grate cooler - high temperature, many dust particles, sticky materials, etc., put forward higher requirements for the sealing of the push plate of the push device. The traditional single sealing...
