Sealing device for trolley of sintering circular cooler

Abstract

The invention discloses a sealing device for a sintering circular cooler trolley, which comprises a movable sealing plate and a static sealing plate, wherein one end of the movable sealing plate is fixed by a pin shaft; the other end of the movable sealing plate is hung in the air and can rotate by using the pin shaft as an axis; the movable sealing plate and the static sealing plate are in contact matching; and the back surface of the movable sealing plate is provided with a heat resistant spring. The sealing device has skillful structure; the movable sealing plate can swing freely; under the action of wind pressure and self weight, the movable sealing plate is attached to the static sealing plate; the irregular movement of a trolley is absorbed by the free swing of the movable sealing plate to realize continuous contact slide type sealing; and the heat resistant spring can control the pressure of the movable sealing plate and the static sealing plate. The sealing device can solve the problem of serious wind leakage among the trolley, a lower wind chamber and an upper smoke hood, and solve the problems of short service life and difficult maintenance of sealing pieces among the trolley, the lower wind chamber and the upper smoke hood, thereby enhancing recycling ratio of smoke gas, enhancing the temperature of the smoke gas, largely enhancing generated electrical energy, efficiently utilizing circular cooling residual heat and benefiting popularization and utilization.

Description

Technical field [0001] The invention relates to a sealing device, in particular to a seal for a sintering ring cooler trolley used for steel companies to seal a sintering ring cooler trolley and a lower air chamber, a sintering ring cooler trolley and an upper fume hood, respectively Device. Background technique [0002] At present, in the steel production process, the energy consumption of the sintering process accounts for about 10% of the total energy consumption, which is second only to the ironmaking process. In the total energy consumption of the sintering process, the flue gas of the sintering machine and the exhaust gas of the ring cooler have nearly 50% of the heat energy. At present, the technology of using this part of heat energy to produce steam and power generation is changing rapidly, but whether this part of heat energy can be efficiently used depends on the ring cooling. The sealing condition of the machine. [0003] Generally, the seal of the sintered ring coole...
