Utility model content
In order to solve the deficiencies in the prior art, the utility model has been designed and developed a kind of cinder haulage system, it uses ash-storing bin to replace the banana-bends structure of evaporative cooler bottom to realize the object of cinder outward transport, this cinder haulage system cost is low, being communicated with of ash-storing bin and evaporative cooler particularly, the excessive not only energy-conservation but also environmental protection of dust while preventing from unloading ash.
The technical scheme that the utility model provides is:
A cinder haulage system, comprising:
Evaporative cooler, it is lowered the temperature and traps crude particle dust in order to the high-temperature flue gas that converter is produced;
Ash-storing bin, described ash-storing bin comprises logical two portions up and down connected with each other, and upper part is cylindrical, and it is conical that lower part is, and described upper part is connected with the outlet of described evaporative cooler by a push-pull valve;
Worm conveyor, it is connected with the lower section port of described ash-storing bin by a rotation unloading valve, for delivery of the cinder being stored in described ash-storing bin.
Preferably, described cinder haulage system is provided with nitrogen big gun and a vibrating motor for deashing on the bulkhead of part under described ash-storing bin.
Preferably, described cinder haulage system is also provided with a deashing access opening on the bulkhead of part under described ash-storing bin.
Preferably, described cinder haulage system, described push-pull valve is connected with a type metal expansion joint that absorbs evaporative cooler thermal expansion displacement by first pipeline in order to the ash of sauntering, and described type metal expansion joint divides and is connected with the top of described ash-storing bin.
Preferably, described cinder haulage system, is also provided with nonmetal being flexible coupling of the described ash-storing bin thermal expansion of absorption displacement between described worm conveyor and described rotation unloading valve.
Preferably, described cinder haulage system, is also provided with a hand operated gate valve between part and rotation unloading valve under described ash-storing bin.
Preferably, described cinder haulage system, described push-pull valve is pneumatic gate valve.
Preferably, described cinder haulage system, also comprises a bucket elevator, and it is connected with described worm conveyor by a second pipe, and the angle of described second pipe and vertical direction is less than 30 degree.
Cinder described in the utility model haulage system, for converter dedusting line, compared with prior art, the one, with ash-storing bin, replaced the banana-bends structure of evaporative cooler bottom, cost is low, avoided because there is no enough spatial design banana-bends structures, and the problem that the investment of banana-bends and built-in machine for zipper is large, the post-processing difficulty that breaks down is larger.The 2nd, the pneumatic gate valve arranging between ash-storing bin and evaporative cooler, easy to operate, open flexibly, can prevent that unnecessary air from entering into the inside of evaporative cooler, after closing, can effectively cut off steel-making waste gas, convenient maintenance upstream device.The expansion of metal of pneumatic gate valve below is energy-conservation absorbs evaporative cooler thermal expansion displacement effectively, and corrosion-resistant long service life.The 3rd, on the lower part bulkhead of ash-storing bin, be provided with nitrogen big gun and vibrating motor, ash removing opening, prevented that cinder from hardening, stopping up in ash-storing bin, guarantee that grey road is unimpeded.And ash-storing bin bottom is divided into cone section, and its insulation can effectively prevent ash silo internal surface dewfall, avoided inside corrosion and sticky ash, reduced workman's cleaning work amount, improved working efficiency.The 4th, worm conveyor and bucket elevator have the feature of failure rate is low, have reduced the failure rate of whole system, guarantee STEELMAKING PRODUCTION.
