Abstract
The utility model provides a blast furnace material flow valve connecting device. The blast furnace material flow valve connecting device is characterized by being formed by combining at least two arc-shaped blocks, wherein the upper end and the lower end of each arc-shaped block are respectively provided with a horizontal flange; the upper end is connected with a feed opening of a hopper; the lower end is connected with a material flow valve. Due to combination of the arc-shaped blocks, the connecting structural strength is effectively enhanced, wear resistance is improved, disassembling during overhaul is facilitated, the connecting device still can be used after one furnace service period, the service life of the connecting device is prolonged, and potential safety hazard is avoided. The connecting device is simple in structure, convenient to disassemble and low in cost.
Description
Technical field
The utility model relates to a kind of coupling device, and particularly a kind of blast furnace material valve coupling device, belong to blast-furnace equipment stud connector design manufacturing technology field.
Background technology
The material valve that existing blast furnace uses is connected with hopper by the cylinder corrugated tube mostly, because the corrugated tube thickness of pipe is limited, and be in for a long time in the raw gas environment, cause corrugated tube material feeding stream to wash away seriously and accelerated wear test, for guaranteeing safe production, when less than a stove, using as a servant the phase, the stop production to overhaul of having to, not only strengthen maintenance workload, increases check man's labour intensity, more can affect normal production and the output of blast furnace, to enterprise, bring financial loss.Therefore be necessary prior art is improved.
Summary of the invention
For solving between existing blast furnace material valve and hopper, adopt corrugated tube to be connected, the serious wear of bringing, life cycle is short, and the maintenance amount is large, affects the normally problem such as smelting of blast furnace, and the utility model provides a kind of blast furnace material valve coupling device.
The utility model completes by following technical proposal: a kind of blast furnace material valve coupling device, it is characterized in that it is combined with at least two arc pieces of horizontal flanges respectively by top and bottom, upper end is connected with the hopper feed opening, lower end is connected with material valve, to pass through the combination of arc piece, increase syndeton intensity, improve wear resisting property, the dismounting during easy access simultaneously.
The Da, lower end, upper end of described each arc piece is little, in order to after combination, form up big and down small cone.
Between described two arc pieces by being welded to connect.
Vertical flange is established respectively in the both sides of described each arc piece, between the arc piece, by vertical flange and bolt, connects in twos.
The arc piece upper and lower end of described combination, by the horizontal flanges on it, be welded to connect with hopper feed opening and material valve respectively, or bolt connects.
The utlity model has following advantages and effect: adopt such scheme, namely by the combination of arc piece, effectively increase syndeton intensity, improve wear resisting property, tearing open, unloading during easy access simultaneously, when using a stove to use as a servant the cycle, still can also use, both extend the work-ing life of coupling device, avoided again the appearance of potential safety hazard.The utility model is simple in structure, and is for convenience detach, with low cost.Be a desirable material valve coupling device in fact.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model;
Fig. 2 is another structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
The blast furnace material valve coupling device that the utility model provides, four arc pieces 3 by upper end band horizontal flanges 2, lower end band horizontal flanges 4 combine, the horizontal flanges 2 of upper end and the flange welding of hopper 1 feed opening, the horizontal flanges 4 of lower end and material valve 5 welding, the Da, lower end, upper end of each arc piece 3 is little, in twos between arc piece 3 by being welded to connect, after combination, form up big and down small cone, as Fig. 1.
Another blast furnace material valve coupling device that the utility model provides, four arc pieces 3 by upper end band horizontal flanges 2, lower end band horizontal flanges 4 combine, the horizontal flanges 2 of upper end is connected by bolt 7 with the flange of hopper 1 feed opening, the horizontal flanges 4 of lower end is connected by bolt 7 with material valve 5, the Da, lower end, upper end of each arc piece 3 is little, and vertical flange 6 is established respectively in both sides, between arc piece 3, by vertical flange 6 and bolt 7, connect in twos, after combination, form up big and down small cone, as Fig. 2.
