Description
Technical field
The utility model relates to dust shield before a kind of portable high retort.
Background technology
At present, steel making working procedure, for reducing production cost, claims the highest molten iron of temperature as raw materials for metallurgy to a upper operation ironmaking.Molten iron is after tapping hole flows out, and for the blast furnace that some trough are longer, the temperature of molten iron is lost relatively big in trough on the way, causes the significant wastage of the energy, returns the operation such as steel desulfurization below, vanadium extraction operation and bring adverse effect.Meanwhile, because of the thermal-radiating effect of high temperature liquid iron, cause molten iron on the curved ditch of molten iron to splash and flue dust is relatively big, thus the production environment near trough is the most severe.
Blast-melted from tapping hole flow out after flow to hot-metal bottle by trough, blast furnace can produce substantial amounts of flue dust during tapping a blast furnace, and wherein tapping hole is by top draft hood sucking-off.For solving substantial amounts of flue dust above trough, typically it is provided above operculum colpi in trough at present, for ensureing good dust removing effects.General blast furnace all can have 2 to 4 tank positions, so trough can flow to each tank position respectively from tap drain.When flowing to No. 1 tank, sand bar can be set in the trough centre of No. 1 tank and No. 2 tanks.Tradition operculum colpi must utilize driving to be hung away by operculum colpi when arranging sand bar, waits sand bar to hang again after setting.Because the traveling crane operculum colpi time is oversize, period has volume of smoke and spills into workshop, has had a strong impact on the working environment in workshop, and has had certain potential safety hazard.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, thus provides dust shield before a kind of portable high retort, easy to use.
The utility model be employed technical scheme comprise that such: dust shield before portable high retort, including the trough for transferring iron melt, the some hot-metal bottles being connected with described trough, some sections of arc operculum colpis it are covered with above described trough, described hot-metal bottle front is provided with top draft hood assembly, some sections of described arc operculum colpis, described top draft hood assembly is connected successively, the sectional dimension of described top draft hood assembly is more than the sectional dimension of described arc operculum colpi, described top draft hood assembly includes being fixedly installed on fixing cover before the tank in described hot-metal bottle front, before length direction and the described tank of described trough, fix cover slide mutually mobile cover before the tank arranged, it is provided with guiding movement mechanism between bottom and the ditch bank of described trough of mobile cover before described tank.
Improve further: described guiding movement mechanism includes being fixedly installed on the guide rail of described trough both sides, rotates before being arranged at described tank the I-shaped roller matched bottom mobile cover and with described guide rail.
Improve further: described top draft hood assembly and arc operculum colpi are double-decker, and the thermal insulation layer being provided with between bilayer.
Improve further: described thermal insulation layer is lightweight heat-proof castable.
Improve further: between the double-decker of described top draft hood assembly and described arc operculum colpi, be provided with some reinforcements.
Improve further: before described tank, on fixing cover, offer manual observation mouth.
By using preceding solution, the beneficial effects of the utility model are: the short and small convenience of dust shield before this portable high retort, only need a people just can be pushed open, both decreased the use of driving, shortened again the operating time when of can arranging sand bar.Only have during sand bar is set outside a small amount of flue gas and overflow.

Wherein: 1, trough；2, hot-metal bottle；3, arc operculum colpi；4, fixing cover before tank；5, mobile cover before tank；6, guide rail；7, I-shaped roller；8, thermal insulation layer；9, reinforcement；10, manual observation mouth.
Detailed description of the invention
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
As Figure 1-3, dust shield before the open a kind of portable high retort of the utility model, including the trough 1 for transferring iron melt, the some hot-metal bottles 2 being connected with described trough 1, some sections of arc operculum colpis 3 it are covered with above described trough 1, described hot-metal bottle 2 front is provided with top draft hood assembly, some sections of described arc operculum colpis 3, described top draft hood assembly is connected successively, the sectional dimension of described top draft hood assembly is more than the sectional dimension of described arc operculum colpi 3, described top draft hood assembly fixes cover 4 before including being fixedly installed on the tank in described hot-metal bottle 2 front, before length direction and the described tank of described trough 1, fixing cover 4 phases are slided mobile cover 5 before the tank arranged, it is provided with guiding movement mechanism between bottom and the ditch bank of described trough 1 of mobile cover 5 before described tank.
The short and small convenience of dust shield before this portable high retort, only needs a people just can be pushed open the when of can arranging sand bar.Both decrease the use of driving, shorten again the operating time.Only have during sand bar is set outside a small amount of flue gas and overflow.
Before tank, mobile cover 5 moves for convenience, reducing the frictional force being subject to bottom it, described guiding movement mechanism includes being fixedly installed on the guide rail 6 of described trough 1 both sides, rotates before being arranged at described tank the I-shaped roller 7 matched bottom mobile cover 5 and with described guide rail 6.
In order to both decrease temperature loss when molten iron flows through trough 1, prevent again steel construction cover body from deforming because of high-temperature baking, described top draft hood assembly and arc operculum colpi 3 are double-decker, and the thermal insulation layer 8 being provided with between bilayer, thermal insulation layer 8 described in the present embodiment is lightweight heat-proof castable that thickness is 140mm, fixed by harrow nail, heatproof 1500 DEG C.
In order to improve the bulk strength of steel construction cover body, between the double-decker of described top draft hood assembly and described arc operculum colpi 3, it is provided with some reinforcements 9.
In order to easily and timely observe molten iron to flow into the situation in hot-metal bottle 2 in trough 1, before described tank, on fixing cover 4, offer manual observation mouth 10.
Of the present utility model general principle and principal character and advantage thereof have more than been shown and described; skilled person will appreciate that of the industry; the utility model is not restricted to the described embodiments; above-described embodiment and explanation described in principle of the present utility model is simply described; on the premise of without departing from the utility model spirit and scope; the utility model also has various changes and modifications; in the range of these changes and improvements both fall within claimed the utility model, the utility model claims scope and is defined by appending claims and equivalent thereof.
