Abstract

The invention discloses a sealing device for an annular cooling trolley, and belongs to the technical field of metallurgy. The sealing device for the annular cooling trolley comprises an external guide rail, an internal guide rail and the annular cooling trolley, wherein the annular cooling trolley is erected between the external guide rail and the internal guide rail, and sealing assemblies are arranged between the annular cooling trolley and the external guide rail and between the annular cooling trolley and the internal guide rail separately; each sealing assembly comprises a sealing frame body fixedly connected with the annular cooling trolley and a sealing ring with a U-shaped section; an opening of each sealing ring faces one side of the annular cooling trolley, and connected with the internal guide rail and the external guide rail separately; a radial sealing piece sliding in the radial direction of each sealing ring is arranged on the sealing frame body, and slidably clamped on the inner side of the sealing ring; and a radial return spring is arranged between each radial sealing piece and the sealing frame body. The radial sealing pieces are in radial sliding connection with the sealing frame body, and the radial sealing pieces and the sealing rings are tightly sealed all the time through elastic return of the radial return springs and counteracting for centripetal force of the annular cooling trolley, so that good sealing effect and operation stability are ensured, and the hot ore cooling quality and the waste heat recovery effect are ensured.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, in particular to a sealing device for an annular cooling trolley. Background technique [0002] The annular cooler is the abbreviation of the annular cooler. Its function is to cool the sintered hot ore unloaded from the sintering machine in time to prevent over-burning, and to recover and reuse the heat of the sintered hot ore, which can effectively avoid heat waste. The principle of the ring cooler is that the bottom of the ring cooler blows cooling air upwards, and the cooling air is heated by the sintered hot ore on the ring cooling trolley to become hot air, and is drawn out through the channel on the upper side of the ring cooler for heat recovery and reuse, thereby sintering the hot ore It can cool down in time to prevent overheating. [0003] In order to reduce the airflow at the bottom of the trolley from escaping from the surroundings and reduce the air leakage rate, it needs to be ...
