Description
Technical Field
The utility model relates to a cold quick-witted sealing device of sintered ring belongs to metallurgical industry iron front system sintering equipment technical field.
Background
The sintering circular cooler is used for uniformly distributing high-temperature sintering ores produced by the sintering machine onto the circular cooling trolley, cooling the sintering ores to be below 150 ℃ from a high-temperature state of 700-800 ℃ in an air blowing cooling mode, and only the cooled sintering ores can be used for carrying out the downstream belt transportation and screening process so as to prevent scalding or firing burning accidents of the belt and screening equipment.
At present, most of the ring cooling machines at home and abroad adopt a rotary annular ring cooling trolley and are cooled by a fixed blast bellows below the annular ring cooling trolley. And the blast air duct is disconnected at the bent part of the track beam of the ring cooling trolley, so that the ring cooling trolley descends to discharge. There is a large gap between the air duct and the ring cooling trolley, and a sealing device is required to prevent the cooling air from leaking out of the gap.
The existing ring cooling machine sealing can be divided into two types: mechanical sealing and water sealing. (1) Mechanical sealing: the sealing method adopts the inner and outer ring dynamic and static sealing modes, generally adopts rubber plates, nylon lining plates or steel wires and the like, and is widely used in the past. The sealing structure has the disadvantages of poor sealing, high air leakage rate, easy damage, short service cycle, frequent replacement and high maintenance cost; (2) water sealing: the sealing effect is good, the air leakage rate is low, and the mode is mostly adopted in the current newly-built production line. The water consumption is very large, the water tank is easy to freeze when the environmental temperature is lower than the freezing point during production in winter, steam or electricity is needed for heat tracing, the cost is increased, and the water tank is seriously corroded by water for a long time and needs to be repaired and replaced regularly; secondly, under the action of the air blower, sinter ore particles can enter the water tank to deposit and cause blockage, and the cleaning difficulty determined by the structural form of the ring cooling machine is larger, so that the conclusion is drawn that the sealing effect of water sealing is good, but the use cost is high.
