Abstract
The utility model relates to a double eccentric turning board type hot blast isolation door, which comprises an outer housing, a door panel and a driving mechanism, wherein, a sealing ring on the door panel is matched with a sealing seat on the outer housing. The double eccentric turning board type hot blast isolation door is characterized in that the double eccentric turning board type hot blast isolation door also comprises a locking lever mechanism and a shaft seal mechanism; the shaft seal mechanism is installed on the outer housing; a driving shaft of the driving mechanism penetrates through the shaft seal mechanism on the outer housing; and the locking lever mechanism is installed on the door panel. The locking lever mechanism comprises a lever, a balance spring, an adjusting lever and a driving shaft sleeve. The shaft seal mechanism comprises the outer housing, a filler group, a gland and a fastening piece. The double eccentric turning board type hot blast isolation door saves installation space greatly, and enables the pipe arrangement to be more compact and reasonable. The wide rotating motion of the door panel avoids the jam of the door panel. A sealing surface that is processed through precision finishing can ensure the whole sealing efficiency. A combined shaft seal structure can avoid the leakage of the isolation door. The hard sealing surface can reduce the maintenance workload, can reduce the overall weight of the isolation door, and can lower the equipment cost.
