A pulverized coal bunker for blast furnace coal injection, comprising a cylindrical bin body and a conical cone bucket, the lower part of the frustum-shaped cone bucket is provided with a lower coal port, and it is characterized in that: there are more than two coal lower ports, and the An inner cone is arranged in the conical bucket. The utility model realizes the simultaneous supply of pulverized coal to one or more blast furnaces, which is convenient for multiple blast furnaces to build a pulverized coal injection station; at the same time, the top cover of the pulverized coal bin and the dust collector on the top of the bunker are integrated, and the lower coal outlet is located at The frustum-shaped conical buckets are distributed on the circumference of the lower edge of the cone at any angle, which can effectively save the height of the factory building, and the structure is simple and compact, easy to operate and maintain, and has a long service life.
Description
Technical field
The utility model relates to a kind of Pulverized Coal Bin, relates in particular to a kind of pulverized coal injection Pulverized Coal Bin.
Background technology
Pulverized coal injection is the requisite technology of current ironmaking technology, and the coal powder injection technology is not only the important means that blast furnace is adjusted, and is to remedy the not enough major measure of coke, not only helps the reduction of cost, and helps energy-conservation.With regard to domestic, external iron-smelting process, pulverized coal injection has become the inexorable trend of blast-furnace technique development, the more important thing is worldwide all in emphasical energy-conserving and environment-protective, small furnace removes or enlarging, reconstruction after higher to the requirement of pulverized coal injection.
In the prior art, blast-furnace coal powder system spray system all is the corresponding Pulverized Coal Bin of a blast furnace, if three blast furnaces so just need be built three Pulverized Coal Bin.Because Pulverized Coal Bin mutually is not equipped with property, when a pulverized coal preparation system need overhaul, then need beat powder pipeline and three Pulverized Coal Bin are carried out interactive coal dust have bad luck through a winding-up jar outlet conduit setting, therefore, system is provided with complicacy, and pipeline and valve increase.
The utility model content
The purpose of the utility model is to provide a kind of Pulverized Coal Bin that can satisfy a plurality of pulverized coal injections simultaneously.
The purpose of the utility model is to realize like this; A kind of pulverized coal injection Pulverized Coal Bin; Comprise cylinder type warehouse and circular platform type awl bucket; Said truncated cone-shaped awl bucket bottom is provided with Xia Meikou, it is characterized in that: said coal mouth down is more than two and is arranged on circular platform type awl bucket lower edge, is provided with inner cone in the said circular platform type awl bucket.
When above-mentioned following coal mouth was two to four, above-mentioned inner cone was provided with corresponding baffle plate to avoid the coal dust deposition.
In order to make the coal dust fluidisation more even, following coal is more smooth, also is provided with on the above-mentioned inner cone and the corresponding fluidisation mouth of following coal mouth quantity.
In order to practice thrift fluidized gas, reduce energy consumption, above-mentioned fluidisation mouth is provided with pneumatic valve, realizes subregion control through pneumatic valve.
In order to make down coal smooth more, above-mentioned inner cone hypotenuse and above-mentioned circular platform type awl bucket hypotenuse angulation are in 25 °.
In order to improve the service life of Pulverized Coal Bin, above-mentioned inner cone top is provided with wearing layer.
Above-mentioned coal mouth down is arbitrarily angled distribution.
In order to save factory building height, roof scrubber directly is seated on the top cover of above-mentioned cylinder type warehouse.
The utlity model has following beneficial effect:
1, the utility model has been realized to one or more blast furnaces coal dust being provided simultaneously, is convenient to many blast furnaces breeze blowing station of building together;
2, the Pulverized Coal Bin top cover and the roof scrubber of the utility model are structure as a whole, and dust exhaustor need not ash bucket and connecting tube, can effectively save factory building height, have reduced workshop steel structure, concrete use amount, have also reduced equipment steel structure use amount.
3, the utility model is simple and compact for structure, and convenient operating maintenance has reduced the plant maintenance amount, has reduced productive costs, has improved service life.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is Fig. 1 cutaway view.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Embodiment, a kind of pulverized coal injection Pulverized Coal Bin comprises roof scrubber 1, cylinder type warehouse 2, circular platform type awl bucket 5, inner cone 10 and top cover 12; Top cover 12 is provided with feed opening, detection mouth, security personnel's nitrogen mouth, manhole 9 etc., and cylinder type warehouse 2 links to each other with circular platform type awl bucket 5, and its weight is delivered on the landing beam through high strength bearing 11 and electronic scale 4; Circular platform type awl bucket 5 is provided with anti-rolling device 3 and temperature measuring equipment 7; Circular platform type awl bucket 5 bottoms are provided with inner cone 10, and following coal mouth 8 is five and is arranged on the circular platform type awl bucket 5 lower edge circumference that inner cone 10 hypotenuses all become 25 ° of angles with circular platform type awl bucket 5 hypotenuses with midperpendicalar; Inner cone 10 tops are provided with wearing layer; Top cover 12 directly links to each other with roof scrubber 1 and constitutes an integral body, and the fluidisation mouth 6 bases position and the quantity of coal mouth 8 down are provided with, and adopts through pneumatic valve and divides section control; Just fluidisation is carried out in this section during corresponding 8 times coals of coal mouth down, coal dust is through getting into the winding-up jar through coal mouth 8 down after the fluidisation.
