Description
Technical field
The utility model relates to the instrument used in aluminium alloy smelting refining process, is specifically related to a kind of refining pipe.
Background technology
When aluminium alloy melt refining, refining agent need be blown into melt by nitrogen or argon gas in the mode of dusting and carry out refining, as shown in Figure 6, a corresponding iron pipe 10 of automatic powder blower 1 in prior art, nitrogen and refining powder are blown into melt in stove by iron pipe 10 and carry out refining, in order to ensure the effect of refining, the pressure adjusting of nitrogen is good, the height that nitrogen after ejection makes melt seethe can not too high (being generally less than 150mm), the height that melt seethes is higher, what produce oxide compound and hydrogen in melt may be larger, larger to the harmful effect of refining effect.For reaching good refining effect, need, with two automatic powder blower refinings, can refining time be shortened like this, the height that when also can control refining, melt seethes, but manipulation require two people and two automatic powder spraying equipment like this, add cost of labor and equipment cost.
Summary of the invention
The purpose of this utility model proposes a kind of refining pipe, uses this refining pipe to improve refining efficiency, can reduce the use of equipment and workman.
A kind of refining pipe described in the utility model, comprise " Y " shape three-port structure be made up of an input tube and two output tubes, input tube is communicated with automatic powder blower by a flexible pipe, two output tubes are used for Jet refining powder in melt, and the exit of described output tube is provided with the flow-guiding structure for expanding refining powder spray regime.
Adopt technique scheme, only need an operative, the refining pipe of " Y " shape three-port structure can reach the effect of two refining pipes in prior art; Adopt this refining pipe, gaseous tension also will reduce, and can control the height that melt seethes more easily, can ensure not occur plugging phenomenon simultaneously; Flow-guiding structure makes refining powder spray regime larger, and refining efficiency is higher.
Further, described flow-guiding structure is the parallel flow deflectors of two of the exit being welded on described output tube, and the section of flow deflector is isosceles triangle, and the drift angle of isosceles triangle is towards in output tube.Adopt said structure refining powder to be fan-shaped ejection in output tube, increase refining scope, there is the advantage that structure is simple, refining efficiency is high.
Further, the exit of described output tube is provided with conical inboard wall, and the diameter of conical inboard wall from inside to outside reduces gradually.The jeting effect of refining powder can be strengthened.
Further, the intersection of described input tube and output tube is provided with smooth circular arc inwall, and the intersection of two output tubes is provided with smooth circular arc inwall.Smooth circular arc inwall can reduce the accumulation of refining powder in refining pipe.
Further, described input tube, in " ┌ " shape, facilitates workman to be stretched in melt by two output tubes.
Further, described input tube is provided with grip part, the outer wall of grip part is provided with multiple plane to facilitate by holding.Workman is facilitated to adjust the position of refining pipe.
The use that the utility model structure is simple, convenient and practical, decrease equipment and workman, reduces production cost, improves refining efficiency simultaneously.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of refining pipe as shown in Figure 1, comprises " Y " shape three-port structure be made up of an input tube 3, two output tubes, and two output tubes are the first output tube 4 and the second output tube 5.Input tube 3 is in " ┌ " shape, and input tube 3 is provided with grip part 9, as shown in Figure 2, the outer wall of grip part 9 is provided with multiple plane to facilitate by holding.As shown in Figure 3 and Figure 4, the exit of the first output tube 4 and the second output tube 5 is provided with the flow-guiding structure for expanding refining powder spray regime, flow-guiding structure is the parallel flow deflectors 7 of two of the exit being welded on output tube, the section of flow deflector 7 is isosceles triangle, and the drift angle of isosceles triangle is towards in output tube.The exit of the first output tube 4 and the second output tube 5 is equipped with conical inboard wall 8, and the diameter of conical inboard wall 8 from inside to outside reduces gradually.Input tube 3 and the first output tube 4 intersection are provided with smooth circular arc inwall, and the intersection of input tube 3 and the second output tube 5 is provided with smooth circular arc inwall, and the intersection of the first output tube 4 and the second output tube 5 is provided with smooth circular arc inwall.Angle in the present embodiment between the first output tube 4 and the second output tube 5 is 120 degree, and in guarantee refining pipe, refining powder expands the refining scope of refining pipe while not piling up.
As shown in Figure 5, input tube 3 is communicated with automatic powder blower 1 by a flexible pipe 2, and the first output tube 4 and the second output tube 5 are for Jet refining powder in melt 6.The utility model all needs a workman just can operate in use, can better control the height that melt 6 seethes, and the Altitude control that melt 6 can seethe by employing the utility model is within 100mm.The height that melt 6 described herein seethes refers to: the difference of altitude of melt 6 liquid level when Jet refining powder and before Jet refining powder.
