Problems solved by technology
The sealing device currently used is a water-sealed structure, which is characterized by a good sealing effect and a small air leakage rate between the upper moving air duct and the lower fixed air duct, but it needs to be equipped with water supply, drainage and control systems, which virtually increases equipment investment. and maintenance, moreover, after a period of time, sinter debris settles in the water tank, which needs to be shut down for cleaning, which affects the normal production of the blast ring cooler

The invention relates to the technical field of forced draft circular coolers, in particular to an air duct sealing device of the forced draft circular cooler, which comprises a lower circular fixed air duct of the forced draft circular cooler, an upper circular movable air duct, and a sealing device arranged between the upper circular movable air duct and the lower circular fixed air duct. The air duct sealing device is characterized in that: screw holes are reserved in the lower part and on the outer air duct wall of the upper circular movable air duct respectively; sealing seats are arranged in the upper part and on the outer air duct wall of the lower circular fixed air duct respectively; and the sealing device consists of a sealing frame, gaskets, a pressing plate, an inner sealing ring and an outer ring, wherein the sealing frame is connected with the inner and outer air duct walls of the upper circular movable air duct by a bolt component respectively; the gaskets are arranged between the sealing frame and the inner and outer air duct walls of the upper circular movable air duct respectively; the pressing plate is connected with the sealing seats by an iron wedge; the innerand outer sealing rings are arranged between the pressing plate and the inner and outer air duct walls of the lower circular fixed air duct respectively; and the top ends of the inner and outer sealing rings are overlapped with a bottom plate of the sealing frame. The air duct sealing device has a simple structure, is convenient to overhaul and ensures good sealing effect.
Description
technical field [0001] The invention relates to the technical field of blast ring coolers, in particular to an air duct sealing device for blast ring coolers. Background technique [0002] The ventilation device of the blast ring cooler is the channel through which the cooling air enters the ring cooler, and is composed of a fan, a fan pipe, an upper moving air duct, a lower fixed air duct and a sealing device. The fan and the fan pipe are fixed parts, the upper movable air duct rotates horizontally around the center of the blast annular cooler with the trolley of the blast annular cooler, and the lower fixed air duct is fixed on the frame. There is a sealing device between the upper moving air duct and the lower fixed air duct. The normal temperature air provided by the blower reaches the lower part of the trolley through the air inlet pipe, the lower fixed air duct, and the upper moving air duct. The cooling air passes through the grate plate of the trolley and conducts ...
