Abstract

The invention discloses a ring cooling machine sealing device and a ring cooling machine. A specific embodiment of the ring cooling machine sealing device is used for sealing gaps between a trolley lower fence plate and an ash hopper bin wall in the ring cooling machine. The ring cooling machine sealing device comprises nozzles and high-pressure fans. The shape of the nozzles adapt to the gaps. The nozzles are connected to the ash hopper bin wall in a sealing mode. The distance between an air outlet and the trolley lower fence plate or between the air outlet and the surface of a sealing part connected to the trolley lower fence plate is within 15 mm to 25 mm and sealed through air curtains sprayed out by the nozzles. The air outlet direction is toward the side, with the larger air pressure, of the two sides of the gap, and the included angle between the air outlet direction and the horizontal direction is smaller than 40 degrees. The high-pressure fans communicate with the nozzles and provide high-pressure air sources for the nozzles. According to the embodiment of the ring cooling machine sealing device, mechanical contact does not exist during gap sealing, so that mechanical abrasion does not exist, and clearing and replacing are not often needed.

Description

technical field [0001] The present application relates to the field of metallurgical technology, in particular to the field of metallurgical devices, and more specifically, to a sealing device of an annular cooler and an annular cooler. Background technique [0002] Annular coolers are widely used in the metallurgical industry, including blast-type annular coolers and draft-type annular coolers, which are used to cool sinter and pellets. [0003] The main equipment of the current ring cooler is a trolley. The trolley is equipped with an upper fence and a lower fence. Under the trolley is a conical ash hopper for receiving bulk materials. The end of the lower fence extends into the ash hopper. . In order to reduce air leakage from the bottom of the trolley, a sealing device is required to seal the gap between the lower fence of the trolley of the ring cooler and the wall of the ash hopper. [0004] Conventional ring coolers are basically sealed with rubber plates. The rubbe...
