Description

Technical Field

[0001] The utility model relates to the technical field of sealed baffle plates, in particular to a high-sealing baffle door. Background Art

[0002] Most of the baffle doors currently used on site use a blade shaft in the shaft mounting hole to rotate the door body through an actuator, and the seal between the door body and the door frame body is formed by extending a steel sheet on the rotating door body in parallel contact with the cross piece in the door frame body. The door frame body and the rotating door body are in the harsh environment of dense flue for a long time. Long-term accumulation of dust, carbon deposits, etc. in different directions and heights leads to poor sealing after closing. Smoke leakage is serious when actually closed, and the baffle door cannot achieve the real sealing effect. During maintenance, operators cannot enter for maintenance due to the harsh conditions such as high temperature and thick smoke caused by leakage.
