Problems solved by technology

[0004] In order to solve the problem that the trolley sealing device is in use, a certain centripetal force will be generated during the circular operation of the trolley, and the trolley will deviate in the radial direction of the circular motion, resulting in a decrease in the sealing performance of the sealing device and a large amount of air leakage , which seriously affects the cooling quality of sintered hot ore and the recovery of waste heat, the invention provides a sealing device for ring cooling trolley

Abstract

The invention discloses a ring cooling trolley sealing device, belonging to the technical field of metallurgy, comprising an outer guide rail, an inner guide rail and a ring cooling trolley; Sealing components are respectively provided between the guide rails; the sealing components include a sealing frame body fixedly connected with the ring cooling trolley and a sealing ring with a U-shaped cross section; the opening of the sealing ring faces the side of the ring cooling trolley, and it is respectively connected with the inner guide rail. It is connected with the external guide rail; the seal frame body is provided with a radial seal that slides along the radial direction of the seal ring, and the radial seal is slidably engaged with the inside of the seal ring; there is a radial reset between the radial seal and the seal frame body spring. The radial seal is connected with the sealing frame in radial sliding, and is elastically reset by the radial return spring, which offsets the centripetal force of the ring cooling trolley, so that the radial seal is always tightly sealed with the sealing ring to ensure a good sealing effect and running smoothly. Stability, to ensure the cooling quality of hot ore and the effect of waste heat recovery.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, in particular to a ring cooling trolley sealing device. Background technique [0002] The ring cooler is the abbreviation of the ring cooler. Its function is to cool the sintered hot ore unloaded from the sintering machine in time to prevent overburning, and to recycle 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 the cooling air upward, and the cooling air is heated by the sintered hot ore on the ring cooling trolley into hot air, and is extracted through the channel on the upper side of the ring cooler for heat recovery and reuse, so as to sinter the hot ore. It can cool down in time to prevent overheating. [0003] In order to reduce the air flow at the bottom of the trolley from escaping from the surrounding and reduce the air leakage rate, it is necessary to seal it by the s...
