Abstract
The invention discloses a converter dry dedusting coarse ash collecting device, and relates to the technical field of converter dry dedusting. The converter dry dedusting coarse ash collecting device comprises an ash bucket connected with a cooler; an ash unloading valve is mounted in an outlet of the ash bucket, and is connected with a feed end of a bucket elevator through an ash discharge pipe; a discharge end of the bucket elevator is connected with an ash storage bin in a high place through a connecting pipe; the ash bucket includes a conical bucket body; and an ash bucket cover plate and an ash inlet pipe connected with the cooler are mounted above the conical bucket body. Compared with the prior art, coarse ash collected by the ash bucket is fed in the bucket elevator through the ash unloading valve, and enters the ash storage bin after vertical hoisting to prevent accumulation on the ground to cause loss and environmental pollution; and an ash scraping machine is not needed for ash scraping to reduce the maintenance cost.
Description
Technical field
The present invention relates to converter dry dedusting technology field, especially a kind of collection dress for converter dry dedusting cinder
Put.
Background technology
Steelmaking converter flue gas ash removal is divided into wet method and dry method two big class, and dry method dust has that water consume is low, no sewage disposal system
Unite, power consumption is low, fan operation is stable, the low advantage of dust emission concentration, flue gas collects dust therein after supercooling.At present
Dry method dust cinder is to be fallen earthward by connecting the discharge of the banana-bends of cooler, is then scraped to ash-storing bin by scrapper conveyor, then enters
Row recycles.Use the domestic steel mill of converter dry dedusting at present, be all using this mode collected and recycle.By
Scrape into ash-storing bin after being to fall earthward in cinder again, scraping machine usage frequency is high, is easily damaged, cause maintenance cost high, once
Break down and can have a strong impact on production；Cinder is piled up on ground, can lead to run off and pollute environment.
Content of the invention
Problem to be solved by this invention is to provide a kind of converter dry dedusting cinder collection device, to solve scraping machine appearance
Fragile, cause maintenance cost high, and the problem of pollution environment.
In order to solve the above problems, the technical solution used in the present invention is：This converter dry dedusting cinder collection device,
Include the ash bucket being connected with cooler, equipped with unloading valve, described unloading valve passes through ash releasing tube and bucket type for the outlet of described ash bucket
The feed end of elevator connects, and the discharge end of described bucket elevator is passed through adapter and is connected with high-order ash-storing bin.
In above-mentioned converter dry dedusting cinder collection device technical scheme, more specifically technical scheme can also be：Described
Ash bucket includes taper bucket body, and the top of described taper bucket body is equipped with ash bucket cover plate and the ash inlet tube connecting cooler.
Further, described taper bucket body is surrounded and is formed by two piece of first strickle being oppositely arranged and two piece of second strickle,
Be provided with arc inside adjacent described first strickle and described second strickle connecting portion slips hawk.
Further, described ash bucket cover plate is provided with ledge and is attached separately to the shrouding at described ledge two ends.
Due to employing technique scheme, the present invention compared with prior art has the advantages that：
1st, the present invention is connected with cooler using ash bucket, the cinder that hopper bottom is collected, and is slipped into bucket lifting by unloading valve
Machine, cinder enters ash-storing bin after vertical-lift；Cinder is avoided to pile up and the environment that leads to run off and pollute on ground, and not
Need to scrape ash using scraping machine, reduce maintenance cost.
2nd, ash bucket includes taper bucket body, the top of taper bucket body equipped with ash bucket cover plate with the ash inlet tube that connects cooler,
Form an airtight space, taper bucket body increases certain SR, obtains extraordinary cinder interception result, cinder is subject to
To the effect of centripetal force, gravity, along with the kinetic energy rejection impinging upon on grey headwall, cinder particle interception rate reaches 100%.
3rd, taper bucket body is surrounded and is formed by two piece of first strickle being oppositely arranged and two piece of second strickle, adjacent first
Be provided with arc inside strickle and the second strickle connecting portion slips hawk, makes cinder smoothly fall into hopper bottom.
