The driver of tight item is corroded, it is ensured that seal-locking mechanism being capable of normal use.
Preferably, rigid locking item inboard is equipped with the gate slot that width is more than baffle door door body thickness, the flexibility
Sealing strip is soft stainless steel, and soft stainless steel is tightly connected with gate slot notch.It is sealed using soft stainless steel and baffle door door body, it will not
It is affected by the high temperature and reduce the service life.
Preferably, the baffle door door body surrounding is equipped with outwardly extending raised line, the flexible sealing strip and raised line
It mutually seals, the thickness of raised line is less than the thickness of baffle door door body, and sealing difficulty can be greatly reduced.
As an improvement, the both sides of the raised line outer end are equipped with the angles R, angle setting and the flexible sealing strip deformation coefficient at the angles R
It is adapted, to obtain better seal effect.
As an improvement, rigid locking item inboard protrudes from both sides sealing structure, the influence for avoiding coal ash from accumulating.
Preferably, the sealing structure is specially：The rigid locking both sides are each provided with a deformable workpiece, often
The both sides of the deformable workpiece of part are connect with rigid locking item and frame seal respectively, can be deformed with the movement of rigid locking item,
Effectively etchant gas is avoided to enter in frame, prevents the driver to rigid locking item from impacting, it is ensured that seal-locking mechanism
Can normal use, with ensure isolation door reliable unlatching.
Preferably, the deformable workpiece is corrugated plating, deformation performance is good, can with rigid locking item and frame can
By welding.
Preferably, the driver of every rigid locking item is multiple cylinders, cylinder push-rod movement synchronism is strong, and rigidity is locked
The movement of tight item is steady, it is ensured that effective sealing of flexible sealing strip and door body raised line inside rigid locking item.
