Anti-liquid wave suppression device for annular air passage end seal transition zone

This application claims priority to Chinese Patent Application No. 200910161229.2, filed on July 24, 2009, entitled "A Circular Air Duct End Seal Transition Zone Liquid Anti-Suppression Device", the entire contents of which is hereby incorporated by reference. This is incorporated herein by reference.

Technical field

The present invention relates to a ring cooler, and more particularly to an anti-liquid wave suppressing device for an annular duct end seal transition zone.

Background technique

The dynamic seal of the annular air duct of the ring cooler is realized by the annular air passage liquid sealing method. Specifically, the fixed installation annular fluid tank and the door type sealing device matched with the annular liquid tank constitute a dynamic seal to the annular air passage. In the cooling zone, a plurality of through holes for facilitating the passage of cooling air are provided at the bottom of the annular liquid tank. The radial sealing section of the door type sealing device is a door type, and the air outlet of the door type sealing device is connected with the air inlet pipe of the trolley. The door type inner ring plate and the door type outer ring plate of the door type sealing device are respectively inserted into the inner ring liquid tank of the annular liquid tank and the liquid of the outer ring liquid tank, and are kept at a distance from the liquid tank bottom plate. The door type sealing device is suspendedly mounted on the trolley support beam of the revolving frame and runs along with the revolving frame; during operation, the cooling air entering the annular duct from the through hole at the bottom of the annular liquid tank passes through the door type sealing device cover The air outlet on the board enters the trolley.

It is well known that there is no need to cool the trolley material in the loading and unloading area of the ring cooler. This area is called the non-cooling zone, and the rest of the area that needs to cool the trolley material is called the cooling zone. In order to ensure that the pressure wind in the cooling zone of the annular duct does not enter the non-cooling zone, it is necessary to seal between the cooling zone and the non-cooling zone of the annular duct.

Under normal technical conditions, a baffle is fixedly mounted at the end of the annular duct to prevent cold air from entering the non-cooling zone. Due to the installation and machining errors of the ring cooler, the door seals may have radial and axial displacements of the ring cooler; when the gate seal cover produces radial runaway and axial displacement, the door type will occur. The scraping between the seal cover and the baffle even damages the baffle. In this way, a gap is generated between the baffle and the door seal cover, so that the positive pressure cooling air flowing at high speed in the annular air passage enters the non-cooling zone from the gap between the door seal and the baffle, thereby The discharge zone of the cooling zone has an impact. In addition, the high-pressure flowing positive pressure cooling wind will cause strong fluctuations in the liquid in the annular liquid tank and the liquid flower, and the liquid flower can enter the non-cooling zone and the trolley with the wind, so that the water in the annular liquid tank is taken away. The liquid seal of the cooling zone is prevented from proceeding normally. Moreover, the liquid entering the trolley will cause the pallet of the trolley to stick to the ash, affecting the ventilation of the raft and the cooling of the material. When the agglomeration is serious, the trolley will be unloaded and reset.

Referring to Figure 1, an annular duct end seal 1 is provided between the existing cooling zone and the non-cooling zone to achieve a seal between the zone II of the cooling zone and the zone I of the non-cooling zone. The annular duct end seal 1 has a distance from the nearest air inlet of the bottom of the annular liquid tank 4, and the annular duct in the range is called the annular duct end seal transition zone III, the end seal The transition zone III is located in the cooling zone II zone.

In the end of the annular air duct sealing transition zone, the lower part is the liquid trough bottom plate, the top part is the door type sealing device cover plate, the two sides are the door type inner ring plate 31 and the door type outer ring plate 32, and the front end is adjacent to the non-circle The annular duct end seal 1 of the cooling zone is at the rear end of the tank duct end plate 61. The liquid channel end plate 61a is a blind plate, and the liquid channel end plate 61 is equal to the liquid channel inner ring plate 44 and the liquid channel outer ring plate 45. The annular duct end seal transition zone III is connected to the inner ring liquid tank and the outer ring liquid tank of the annular liquid tank.

The door type sealing device of the annular air passage is moved together with the trolley. When the air outlet on the cover plate of the door type seal passes through the end portion of the transition zone III, the liquid of the annular liquid tank 4 enters the table with the wind. The car, the liquid entering the trolley will make the raft of the trolley viscous and agglomerate, affecting the venting of the raft and the cooling of the material. When the agglomeration is serious, it will cause the unloading and resetting accident of the trolley.

Therefore, how to provide a liquid-proof wave suppressing device for preventing the liquid in the transition portion of the annular air passage from entering the trolley with the wind is a technical problem to be solved by those skilled in the art.

A flexible sealed inner baffle and a flexible seal are respectively disposed between the inner ring plate of the liquid-proof wave suppressing device and the inner ring plate of the door type air passage, and between the outer ring plate of the liquid-proof wave suppressing device and the outer ring plate of the door type air passage. Outer baffle

When the door type seal moves, the flexible seal inner baffle and the flexible seal outer baffle are in contact with the door type inner ring plate and the door type outer ring plate, respectively, and have relative movement.

Preferably, the liquid-proof wave suppressing device end plate is connected to the inner ring plate of the liquid-proof wave suppressing device, the outer ring plate of the liquid-proof wave suppressing device, and the liquid tank bottom plate.

Preferably, the liquid-proof wave suppressing device connecting plate and the liquid-proof wave suppressing device inner ring plate and the liquid-proof wave suppressing device outer ring plate, the annular liquid groove air channel inner ring plate, the annular liquid groove air channel outer ring plate and the liquid The groove bottom plate is anti-leakage connection.

Preferably, the liquid-proof suppressing device end plate and the connecting plate, and the inner ring plate of the liquid-proof wave suppressing device and the outer ring plate of the liquid-proof wave suppressing device are made of an anticorrosive material.

Since the annular air passage end seals the transition zone liquid-proof suppressing device, the method comprises: setting the annular air duct The end seal sealing section of the annular liquid tank bottom plate, and adjacent to the annular air passage end seal side of the liquid-proof wave suppressing device end plate and the connecting plate. Since the end plate of the liquid-proof suppressing device is a blind plate, the connecting plate has a U-shaped structure along a radial section of the ring cooler; therefore, when the pressurized wind enters between the end plate of the liquid-proof preventing device and the connecting plate, the connecting plate can The pressure wind is directed such that the pressure wind enters the venting opening in the cover of the door seal along the transition zone in front of the end plate of the liquid proofing device.

When the air outlet of the door seal cover moves, enters the end seal transition zone until the air outlet of the door seal cover leaves the end seal transition zone, the flexible seal inner baffle and the flexible seal The outer baffle will be in contact with the inner ring plate of the door type air duct and the outer ring plate of the door type air passage, and have relative motion.
