At present, the refine pipe of powder feeding of blowing in many aluminium melting furnace all adopts seamless steel pipe, this refine pipe easily corrodes, ferrum is due to high temperature and by aluminum corrosion in aluminum liquid, and iron tramp enters in aluminum liquid, affects quality, the life-span of refine pipe is short simultaneously, this kind of refine pipe is all straight-through, and gas outlet is only in one end of iron pipe, and degassing effect is not good.And the blowning installation used on large aluminium melting furnace, often structure is complicated, relatively costly.
Summary of the invention
The main purpose of the present invention is to provide a kind of air blowing powder feeding refine pipe, it is possible to make refining agent be uniformly distributed, and while improving refining effect, does not affect aluminum liquid quality.
For achieving the above object, the technical solution used in the present invention is: a kind of air blowing powder feeding refine pipe, including conveying pipe, branched pipe and bleed pipe, described branched pipe is transverse tube, the same sidewall of transverse tube is interval with more than one installation port, described conveying pipe one end is connected with dust feeder, and the other end is connected with the middle part of branched pipe, and now conveying pipe and installation port lay respectively at the both sides of branched pipe；Described bleed pipe is installed on installation port, and its quantity is consistent with installing port number；Described bleed pipe is provided with spray orifice.
Preferably, described bleed pipe is bend pipe, and the bending direction of every bleed pipe is consistent, and the termination of described bleed pipe is enclosed construction, and along pipe direction of extension, on tube wall, interval arranges multiple spray orifice.
Preferably, adjacent two spray orifice on every described bleed pipe lays respectively on the not ipsilateral of bleed pipe tube wall.
Preferably, described bleed pipe is bend pipe, and the bending direction of every bleed pipe is consistent, and the termination of described bleed pipe is enclosed construction, and along pipe direction of extension, on tube wall, interval arranges 3-5 group spray orifice, and often group spray orifice includes two spray orifices facing each other.
Preferably, the described quantity installing port is 3-5.
Preferably, described bleed pipe adopts graphite material to make.
Preferably, the length of described bleed pipe is 0.8-1.5m, and the vertical height of bending is 0.5m.
Preferably, described bleed pipe and installation port are respectively provided with the screw thread cooperated, and are threaded connection.
Preferably, described conveying pipe is straight tube.
The operation principle of the present invention is: put in refining furnace by air blowing powder feeding refine pipe, bleed pipe is made to be partly submerged in aluminum liquid, it is blown into noble gas and powdery refining agent to conveying pipe, constantly it is being blown in process, powdery refining agent is entered in bleed pipe through branched pipe by noble gas, and enter in aluminum liquid from the spray orifice bleed pipe tube wall, aluminum liquid is carried out degasification slagging-off.
Beneficial effects of the present invention:
1, the present invention adopts graphite bleed pipe in the part immersing aluminum liquid, has advantage corrosion-resistant, high temperature resistant, that not easily melt, solves iron pipe easily and the problem of aluminum-water reaction, makes described refine tube lifetime long.
2, the present invention is provided with spray orifice on bleed pipe tube wall, being intervally arranged so that noble gas and powdery refining agent are from different orientation ejections of spray orifice, makes bubble uniformly tiny, thus good purification and gas effciency are high.
3, the bleed pipe quantity of the present invention is multiple, and in bending so that gas and the ejection of powdery refining agent are more uniformly distributed.
4, bleed pipe of the present invention and installation port are threaded connection so that structure is more simple and easy, easy for installation.
