liquid wave suppression device in an end-sealing transition region of an annular air duct

摘要

A liquid prevention and wave suppression device for use at a sealing transition region of an end part of a circular air duct is provided, which includes: an end plate (22) of the liquid prevention and wave suppression device which has the same height as an inner circular plate and an outer circular plate (44, 45) of an air duct of a circular flume, an inner circular plate and an outer circular plate (231, 241) of the liquid prevention and wave suppression device which has the same height as and connects to the end plate (22) of the liquid prevention and wave suppression device, an inner transition plate (211) of the liquid prevention and wave suppression device which connects to the inner circular plate (231) of the liquid prevention and wave suppression device and the inner circular plate (44) of the air duct of the circular flume, an outer transition plate (212) of the liquid prevention and wave suppression device which connects to the outer circular plate (241) of the liquid prevention and wave suppression device and the outer circular plate (45) of the air duct of the circular flume. The end plate (22) of the liquid prevention and wave suppression device is arranged on a near side of an end sealing device (1) of the circular air duct and adjacent to it. The radial width of the end plate (22) of the liquid prevention and wave suppression device is greater than the distance between the inner circular plate and the outer circular plate (44, 45) of the air duct of the annular flume, and it is separated by a predetermined distance from an inner circular plate and an outer circular plate (31, 32) of a door-shaped air duct. When the door-shaped sealing device moves, a relative movement exists between the inner circular plate and the outer circular plate (231, 241) of the liquid prevention and wave suppression device and the inner circular plate and the outer circular plate (31, 32) of the door-shaped air duct. The liquid prevention and wave suppression device (2) can effectively prevent liquid at the sealing transition region of the end part of the circular air duct from entering a trolley with the wind.
