Abstract

The invention discloses a high-rotating-speed and high-temperature dryer sealing piece. The high-rotating-speed and high-temperature dryer sealing piece comprises an end gland, a spring sealing sleeve, a thermometer, a one-way valve and a positioning ring, wherein a shaft sleeve is mounted on the inner side of the end gland, a shaft sleeve O-shaped ring is mounted on the inner side of the shaft sleeve, a mounting hole is formed in the end gland, and a sliding rod is mounted on the end gland; an extending rod is installed on the sliding rod through a limiting lantern ring, one end of the extending rod is connected with a positioning sleeve, a fastening threaded hole is formed in the positioning sleeve, a fastening bolt is installed in the fastening threaded hole, and a double-layer sealing ring is installed on the inner side of the fastening threaded hole; and the positioning ring is arranged on one side of the positioning sleeve. The high-rotating-speed and high-temperature dryer sealing piece is provided with a static ring O-shaped ring, a movable ring O-shaped ring, the shaft sleeve O-shaped ring and an atmosphere end sealing ring, loss caused by contact and mutual friction between connecting pieces is avoided, the service life of the sealing piece is prolonged, and the sealing effect of long-time use is guaranteed.

Description

technical field [0001] The invention relates to the technical field of seals, in particular to a seal for a high-speed high-temperature dryer. Background technique [0002] The dryer has been successfully used in food, chemical, petrochemical, dye, industrial sludge and other fields. The paddle dryer is a horizontal stirring dryer mainly based on conduction. The main structure is a W-shaped shell with a jacket, which is equipped with a pair of hollow low-speed rotating hollow shafts. There are several stirring blades welded on the shaft. The jacket and the hollow stirring blades are connected with a heat carrier. At the same time, the material is heated. The heat carrier is usually sent in from the middle of the dryer, passes through the surface of the material layer in a stirring state, and is discharged from the other side. If there are other needs, the machine can be designed with two or more shafts. There are generally two to four hollow stirring shafts arranged in t...
