Description
Technical field
The utility model relates to a kind of feedway for blast furnace raw material.
Background technology
Still blast furnace is being used now---the iron and steel enterprise of the long flow process of converter, because the main feed stock for blast furnace of blast furnace remains sintering deposit, therefore inevitably all will be equipped with sintering machine to produce sintering deposit.Because sintering machine rhythm of production and blast fumance rhythm exist certain difference, add that blast furnace materials kind is more, need during material loading constantly to switch, therefore in blast furnace hopper, upper sintering deposit just needs discountinuity to carry out, when sintering machine is normally produced, its sintering deposit output is then successional, therefore transfer feed bin is configured with in the sintering deposit finished product transport systems of general producer all between sintering machine and blast furnace, exactly the sintering deposit that sintering machine is produced first is transported in transfer feed bin, then discharge from the feed opening below transfer feed bin, blast furnace hopper is transported to again by the band conveyor under storehouse, transfer feed bin is utilized to solve contradiction between sintering machine continuous seepage and blast furnace discountinuity material loading.Due to current blast furnace and sintering machine scale all increasing, what cause transfer feed bin also to design is more deep, when more empty in transfer feed bin, the drop that sintering deposit falls from Hatch Opening is just larger, easily article are broken into pieces because sintering deposit belongs to, often cause a part of sintering deposit to cause when falling from Hatch Opening to break into pieces, because blast furnace aspect is the powder that blast furnace cannot use depending on being less than the sintering deposit of 5mm particle diameter, part is caused to be become powder by the sintering deposit broken into pieces, blast furnace is caused to use, have to return sintering machine and carry out reheating, so not only cause energy dissipation, also sintering deposit powder is made to cause airborne dust and environmental pollution in the transport returning sintering machine and transport process.In addition, even if sintering deposit does not break below 5mm into pieces, the granule grade particles of 5mm ~ 10mm in the sintering deposit of blast furnace also can be caused to increase, but the medium and small grade of blast furnace feeding raw material increase the permeability to air that can affect in blast furnace, BF Technology in Bao Steel index can be caused to reduce, blast furnace economic benefit can be affected.
Utility model content
The utility model provides a kind of feedway for blast furnace raw material, its reasonable in design, easy to use, sintering deposit can be reduced break into pieces, improve the degree of utilization of resource, save the energy, decrease airborne dust, avoid environmental pollution, improve economic benefit, solve problems of the prior art.
The utility model for solving the problems of the technologies described above adopted technical scheme is: it comprises one group of transfer feed bin be arranged side by side, the first band conveyor matched with its feed opening is provided with in transfer feed bin bottom, two track girders be arranged in parallel and the second band conveyor is provided with above transfer feed bin, two track girders are provided with the dummy car matched with it, guide pulley and lower guide pulley on the upper and lower of dummy car is connected with respectively, upper guide pulley is positioned at the front side of lower guide pulley, the upper strata load-transfer device of the second band conveyor walks around guide pulley and lower guide pulley, on dummy car is positioned at, below guide pulley, the both sides, position of front side are respectively equipped with a short chute be obliquely installed, the cross-sectional plane of two short chutes is splayed, between two short chutes, there is material space, each short chute upper end thereof one discharging turnover panel, on dummy car, the position corresponded to below two short chutes is provided with material path, the 3rd band conveyor matched with it is provided with below the second band conveyor front end.
Dummy car is provided with actuating device.
Dummy car is provided with control two discharging turnover panel open or closed control setup.
Two short chutes are symmetrical arranged.
It is inclined when two discharging turnover panels close.
Two discharging turnover panels are vertical state when opening.
Two track girders are connected on the Vierendeel girder of transfer feed bin by strut member.
Described upper guide pulley is positioned at the middle part of dummy car, and described lower guide pulley is positioned at the rear portion of dummy car.
The utility model adopts such scheme, has the following advantages:
1, the utility model can make full use of the floor time to blast furnace hopper material loading, make sintering deposit do not enter transfer feed bin and directly by the second band conveyor, the 3rd belt haulage to blast furnace hopper, break into pieces to reduce sintering deposit, improve the degree of utilization of resource, save the energy, decrease airborne dust, avoid environmental pollution, improve economic benefit.Specifically, if the second band conveyor is carried be sintering deposit (or other is easy to the blast furnace raw material broken into pieces) time, open two discharging turnover panels on dummy car, sintering deposit is fallen from the load-transfer device of guide pulley on the second band conveyor, through on dummy car cross material space, again fall back to the second band conveyor after material path under guide pulley place load-transfer device on, the 3rd band conveyor again by matching with the second band conveyor, is transported to blast furnace hopper by sintering deposit.Because the drop between upper guide pulley and lower guide pulley is very little, because this reducing the fragmentation causing sintering deposit.
If 2 second band conveyors are carried be blast furnace raw material (as raw ore, lump ore, pellet, the coke etc.) not easily broken into pieces time, two discharging turnover panels on closed dummy car, the blast furnace raw material not easily broken into pieces is fallen from the load-transfer device of guide pulley on the second band conveyor, by the short chute landing of two on dummy car, finally fall in transfer feed bin from dummy car both sides.Time to be needed, the blast furnace raw material in transfer feed bin falls the first band conveyor by its feed opening, and then is transported to blast furnace hopper.Short chute is obliquely installed, and the cross-sectional plane of two short chutes is splayed, and this structure design is conducive to blast furnace raw material along short chute landing.When the sintering deposit in transfer feed bin is so not empty, the drop fallen from Hatch Opening due to sintering deposit is smaller, decreases the fragmentation causing sintering deposit, and aforesaid way therefore also can be adopted to be kept in.
3, inclined when two discharging turnover panels close, be conducive to the blast furnace raw material that guide pulley falls from the second band conveyor and be slipped on short chute along discharging turnover panel.
4, be vertical state when two discharging turnover panels are opened, be conducive to guide pulley falls from the second band conveyor blast furnace raw material through on dummy car cross material space, material path after again fall back on the load-transfer device at guide pulley place under the second band conveyor.
5, on dummy car, be provided with actuating device, dummy car be provided with control two discharging turnover panel and open or closed control setup.Can be convenient to control dummy car like this to move on track girder and two discharging turnover panels are opened or closed.
