Description
Affiliated technical field
The utility model relates to a kind of guiding device that the molten iron and the liquid slag of blast furnace are imported to iron ladle, slag ladle, particularly a kind of guiding device of diversion trench vertical oscillation.
Background technology
In blast furnace iron-making process, collect smelting the molten iron or the liquid slag of coming out, two kinds of forms of general employing, a kind of is fixing trough form, another kind is an active iron ditch form, usually adopt the fixedly process form of trough in the blast furnace of past below 1000m3, molten iron is collected in the iron ladle, and this Technology makes that table length is longer, and investment is many, airborne dust point is many, be difficult for gathering dust, because curb has certain gradient, molten iron and slag could flow simultaneously, this makes that the table obliquity is big, is unfavorable for the table planarization.At all drawbacks, at present nearly all blast furnace is all swung the device of chute by a kind of molten iron, the molten iron of liquid state or slag is collected in iron ladle or the slag ladle gone.By electric motor driven vertical oscillation chute device is the equipment of having used comparative maturity at present, electric motor driven vertical oscillation chute device mainly is made up of diversion trench, diversion trench carriage, bearing bracket, electric motor and crank connecting rod apparatus etc., diversion trench is a steel construction piece, be lined with refractory materials in the groove, be arranged on the diversion trench carriage.The diversion trench carriage by pair of bearing with the weight of equipment vertical transmission to the architecture basics plane, master controller in the transmission mechanism can transmission equipment the angle signal of swing, the about 10KW of transmission mechanism power of motor, chute works better pendulum angle ± 10 °, working time about 6s, 30 ° of greatest limit pendulum angles are realized swing with handwheel under the accidental states such as power failure.The shortcoming of this kind equipment is Heavy Weight, complex structure takes up an area of greatly, and transmission rig is arranged on the casting house platform simultaneously, be difficult for improving the planarization of casting house, when changing body, the disengaging of kinematic link and carriage is more loaded down with trivial details, and the working conditions of long connecting rod is relatively poor, during integral replacing chute body, it is comparatively strict careful that lifting is required, and need be by external force (cucurbit hangs) with among oblique taking-up of chute housing and the insertion chute carriage, and the dedusting fan housing can't be realized fully-closed fully.
Summary of the invention
In order to overcome the deficiency of existing electric motor driven vertical oscillation chute equipment, it is convenient that the utility model provides a kind of apparatus body to change, and transmission rig is simple, can realize the guiding device of the chute vertical oscillation of the molten iron of casting house planarization requirement and liquid slag.
Technical solution of the present utility model is: a kind of blast-melted and liquid slag vertical oscillation guiding device, by bearing bracket, the diversion trench carriage, diversion trench, transmission connection piece, drive element is formed, the diversion trench carriage is the steel welding structure, the welded type diversion trench is set directly on the diversion trench carriage, the diversion trench carriage is installed on the bearing bracket, the direct level of the bolster of bearing bracket is installed on the structural beams of both sides, gudgeon on the diversion trench carriage hangs on the bolster of bearing bracket, drive element adopts single hydraulic cylinder, have position transducer on the hydro-cylinder, transmission connection piece is single connecting rod form, one end of single connecting rod is associated on the diversion trench carriage, the other end is hinged by articulated joint and hydro-cylinder, single connecting rod and single hydraulic cylinder are installed in dedusting fan housing outside, hydro-cylinder drives diversion trench on diversion trench carriage and the diversion trench carriage together around the bolster rotation of bearing bracket by single connecting rod, thereby realizes the normal swing of chute or the accident swing when having a power failure.
The beneficial effects of the utility model are: realize the automatic operation of hydro-cylinder under normal and accidental state by hydraulic way, hydrostatic transmission is in light weight, and is simple in structure, takes up an area of little.The syndeton of chute gudgeon and free bearing is simple, being convenient to equipment integral changes, kinematic link can be realized the disengaging with the diversion trench carriage fully outside the dedusting fan housing, when body is changed, the people need not operate in fan housing, thereby the replacing that makes the diversion trench carriage is also greatly simplified, and complete assembly is placed on below the table plane, can realize the casting house planarization and improve the requirement of casting house dedusting environment friendly.

Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
A kind of blast-melted and liquid slag vertical oscillation guiding device is made up of bearing bracket 1, diversion trench carriage 2, diversion trench 3, transmission connection piece 4, single hydraulic cylinder 5, has position transducer on the single hydraulic cylinder 5.Diversion trench 3 is arranged on the diversion trench carriage 2, two side lower parts of diversion trench 3 are provided with limiting plate 6, limiting plate 6 is a steel plate, the one side of limiting plate 6 is up-narrow and down-wide streamlining, diversion trench 3 is undertaken spacing by limiting plate 6, make diversion trench 3 moving of vertical direction in swing, can not occur, limiting plate 6 be arranged so that diversion trench 3 and diversion trench carriage 2 contraposition and disengaging easily.Diversion trench carriage 2 is installed on the bearing bracket 1, the bolster level of bearing bracket 1 is installed on the structural beams of both sides, gudgeon on the diversion trench carriage 2 hangs on the bolster of bearing bracket 1, and this kind structure makes when needing to change diversion trench 3, can easily diversion trench 3 be shifted out in the lifting process.The transmission connection piece 4 of this device is single connecting rod form, and an end of single connecting rod is associated on the diversion trench carriage 2, and the other end is hinged by articulated joint and single hydraulic cylinder 5.
The mode of operation of this device is as follows: two iron ladles are placed on respectively on two adjacent railways, one of them iron ladle places diversion trench 3 belows of this device, pass through diversion trench, molten iron or liquid slag flow in the iron ladle, when this iron ladle filled with, primer fluid cylinder pressure 5 made diversion trench 3 quick vertical oscillations, thereby make diversion trench 3 commutations, molten iron or liquid slag are flowed in another jar.Simultaneously the train molten iron or the liquid slag ladle that will fill with removed, and moves into another slack tank, and the above repeatedly cycle is till molten iron or liquid slag have flowed.
During works better, drive kinematic links by hydro-cylinder 5 and realize that its pendulum angle signal is by the position transducer output that is contained on the hydro-cylinder 5 to diversion trench 3 and diversion trench carriage 2 swinging operation in vertical direction; Under loss of power accident state, the Hydraulic Station that is equipped with for this hydro-cylinder provides propulsion source by energy storage or manual pump for oil cylinder, to reach round-the-clock automatic operation.
Pressure 8～the 13Mpa of this device Hydraulic Station oil sources, the normal pendulum angle of chute ± 10 °, about 6 seconds of working time, 30 ° of greatest limit pendulum angles, the hydro-cylinder 5 of this device can be incorporated the stokehold Hydraulic Station into.
