Description
Technical field
The present invention relates to a kind of State of Blast Furnace liftout jar, being applied to iron-smelting blast furnace does not have in the bell furnace top system (also jar, three jars or four jars of no clock furnace top systems).
Background technology
In no bell furnace top system (non-bell furnace top charging equipment), batch can is the container that is used for depositing feed stock for blast furnace temporarily, guarantees furnace pressure.According to the quantity of batch can be divided into string jar, and jar, three jars and four jars of no clock furnace top systems.In this, have only the batch can medullary ray of string in the can system can be fully and the blast furnace central lines, can guarantee the blanking characteristic that material is good.In other three systems, all there are some defectives in the batch can blanking:
1. the center that the raw material barycenter departs from blast furnace in the batch can, horizontal initial rate was bigger when raw material arrived distributor chute, caused similar oval-shaped cloth, rather than ideal annular cloth.
2. raw material is that horizontal velocity is big, the batch can lower part equipment is caused wash away, and influences service life of equipment.
3. receive the batch can shape affects owing to raw material is mobile, blanking is prone to form center flow or tubular type flows, the material instability, and in time, lacked for a long time.
4. raw material forms easily particle segregation in the blanking process, is main in certain time period blanking with oversize material, and is main in another time period with piece material.
These defectives have restricted the application and the development of multiple tank non-bell furnace top charging equipment.
Summary of the invention
The object of the present invention is to provide a kind of State of Blast Furnace liftout jar, this batch can reduce the horizontal velocity of blast furnace blanking.
To achieve these goals, the technical scheme that the present invention taked is: a kind of State of Blast Furnace liftout jar, and it comprises tank body, and the top of tank body is provided with opening for feed, and the opening for feed place is provided with feed cap, and the bottom of tank body is provided with discharge port; It is characterized in that: tank body constitutes integrative-structure by upper cone section, cylindrical section and lower cone section; Cylindrical section is between upper cone section and lower cone section; Upper cone section is positioned at the top of cylindrical section, and the lower end external diameter of upper cone section is greater than the upper end external diameter, and the lower end external diameter of lower cone section is less than the upper end external diameter; Upper cone section and lower cone section all are oblique centrums; It is vertical leaving the nearest bus of blast furnace medullary ray in the lower cone section; Leaving nearest bus and the angle between the vertical line of blast furnace medullary ray in the upper cone section is 1～8 °, and the bus from blast furnace medullary ray farthest in upper cone section and the lower cone section tilts.
Bus and horizontal angle from blast furnace medullary ray farthest in the described lower cone section are 45 °～60 °, and the angle value between other buses and the sea line increases on the basis of this value continuously, up to 90 °.
Compare with the batch can of traditional form, the raw material in the batch can of bulge shape, the horizontal throw of its barycenter and blast furnace medullary ray is littler.The present invention reduces the horizontal velocity in the raw material decline process through the cross-sectional shape of adjustment batch can, improves the materials flow curve, improves equipment life, stablizes reinforced flow, reduces the particle segregation that occurs in the blanking process.
The invention has the beneficial effects as follows:
1, the batch can of this shape of the present invention can reduce the horizontal velocity of blast furnace blanking, reduces raw material to the washing away of batch can bottom device, and prolongs its work-ing life.
2, the batch can of this shape of the present invention when reducing the horizontal velocity of blanking, can also help improving oval cloth, makes it can be near annular cloth.
3, the batch can of this shape of the present invention; On with its lower cone section when the bus of blast furnace medullary ray farthest and horizontal angle are controlled between 45 °～60 °; Flowing of the inner raw material of batch can is the state near overall flow, helps reducing the particle segregation phenomenon of materials flow.
