Description
Technical field
The utility model relates to smelting equipment technical field, specifically a kind of furnace cupola.
Background technique
Furnace cupola is low in cost since its structure is simple, and continuous tapping amount is big and is widely used in in Cast Iron Production,
Furnace cupola carries out warding off furnace before the use after building, i.e., refractory brick is built by design requirement inside cupola well, in fire resisting
The fire clay good with mixing, wards off into the required type of furnace, the form and size of the type of furnace are depending on the actual demand of each factory inside brick layer.
The shaft of general furnace cupola be all it is integrated, it is immovable, thus operator need to enter furnace interior into
Row wards off furnace, inconvenient for operation when furnace diameter is smaller, and uneven, the not consolidation for often leading to that furnace wall wards off are melted in subsequent molten iron
It is easy to cause furnace wall to fall off too early in the process, seriously affects the service life of furnace cupola.
Hot air container is generally equipped with above cupola crucible, hot-blast stove chamber absorbs the burner gas residual heat of preheating zone, and preheating air inlet will
Wind-warm syndrome improves, and wind-warm syndrome is higher, and coke consumption is lower, while melting rate is higher, and energy-saving effect is more obvious, and the wind-warm syndrome of general furnace cupola
200 DEG C only up to be reached.
Summary of the invention
The purpose of this utility model is exactly to fix to solve existing cupola body, it has not been convenient to ward off furnace, service life
It does not grow, the bad problem of energy-saving effect provides a kind of furnace cupola for conveniently warding off furnace, and wind-warm syndrome is up to 300 DEG C.
The concrete scheme of the utility model is: a kind of furnace cupola, including furnace body, and furnace body is fixedly mounted on a platform,
Furnace body, which is located above platform, is equipped with feed opening, and chimney is housed above feed opening, dust-extraction unit is housed above chimney, furnace body is located at flat
Hot air container is housed below platform, cupola well is housed, bosh gas index is equipped with several burners, before being equipped in front of cupola well below hot air container
Furnace, the hot air container bottom are equipped with air inlet, and air inlet connect by pipeline with a blower, hot air container top set there are two outlet air
Mouthful, each air outlet connects a hot air pipe, is connected to inside hot air pipe and cupola well, cupola well is divided into cupola well upper section and cupola well lower section two
Part, cupola well upper section are fixedly connected with hot air container, and cupola well lower section can be separated with cupola well upper section, and cupola well lower section bottom is equipped with rolling
Wheel.
Cupola well lower section described in the utility model and cupola well upper section pass through flanged joint.
Hot air container described in the utility model is divided into upper section flue and lower section flue and passes through flanged joint, upper section flue and lower section
Flue is made of an inner cylinder and an outer cylinder, forms annular housing between inner cylinder and outer cylinder, in annular housing from top to bottom
Equipped with several pieces of annular partitions parallel with end face, every piece of annular partition is equipped with a through-hole, per adjacent two pieces of annular partitions
Through-hole between be equipped with one piece of longitudinal baffle.
Inner tank theca described in the utility model is equipped with several pieces of longitudinally arranged gussets, all gusset interlaced arrangements.
Utility model works principle is as follows: cupola well lower section can be removed when operative employee wards off furnace and be separated with cupola well upper section,
Furnace is warded off after separating again, cupola well lower section is moved back to original position again after having warded off furnace, flanged joint position, which fixes can be completed, wards off furnace
Work；Wind in the utility model hot air container flows from bottom to top along annular housing, carries out with the gusset being arranged in annular housing
Heat exchange, to improve wind-warm syndrome, into burner hearth, due to being equipped with longitudinal baffle between the through-hole of adjacent two layers annular partition, wind exists
Using through-hole stream upper layer, the flowing stroke of wind after a whole circle must be flowed around inner cylinder when flowing between two layers of annular partition
It lengthens significantly, the time of heat exchange greatly prolongs.
It is easy to operate when warding off furnace that the utility model has the advantage that compared with prior art, guarantees quality, extends soaring
Furnace service life, the wind-warm syndrome after hot air container heat exchange is up to 300 DEG C, and coke consumption reduces, while melting rate improves, and energy-saving effect is non-
Chang Mingxian.
