A nozzle body is provided with a conical delivery mouth and adopts materials including zirconium oxide and boron nitride; a circle of isolation groove is arranged on the bottom surface of the nozzle body; fittings are made of strength graphite through lathe machining; the nozzle body is fixed at the bottom of a crucible through thread; the conical surface of the nozzle is matched with the conical surface of the bottom of the crucible; a protection tube is arranged on the lower part of the nozzle body; the protection tube is divided into an upper part and a lower part and is made of strength graphite through lathe machining; the upper protection tube is in threaded connection with the lower protection tube; the upper protection tube is in threaded connection with the nozzle body; the bottom of the lower protection tube is inserted into the central hole of an auxiliary nozzle. The delivery tube is adopted to enable the flow direction of alloy to be accurate; the alloy drop cannot spread along bottom surface of the delivery tube, is uneasy to drop on the auxiliary nozzle and is uneasy to block; the protection tube can effectively ensure the stability of liquid flow; the split-type design can slow down heat conductivity and reduce damage degree on atomization nozzle system and improve productivity.
Description
Technical field
The utility model belongs to the alloy atomization technical field, particularly a kind of high-melting-point alloy atomizing catheter.
Background technology
Existing catheter is generally as a whole, does not have protection tube, and fluid guidance port is positioned at bottommost, and does not have isolating trenches.Alloy liquid stream has just flowed out the interference that fluid guidance port will be subjected to the high speed atomization air flow during atomizing, causes liquid stream to be sprawled along the catheter bottom surface, is stained with on the pilot jet, can stop up catheter after accumulating to a certain degree, causes the interruption of atomization process.And the conduction of the heat of integral type catheter is very fast, and the heat of the alloy liquid of fusion is easy to pass on the pilot jet by catheter in the crucible, can shorten the service life of pilot jet greatly.
Summary of the invention
The purpose of this utility model provides a kind of high-melting-point alloy atomizing catheter.
A kind of high-melting-point alloy atomizing catheter; it is characterized in that; mouth body 1 has the taper fluid guidance port, and mouth body 1 bottom surface has a circle isolating trenches 6, and accessory 2 is fixed on crucible 5 bottoms by screw thread with mouth body 1; the cone match of the conical surface of mouth body 1 and crucible 5 bottoms; protection tube is arranged at mouth body 1 bottom, and protection tube is divided into upper and lower two parts, and last protection tube 3 adopts with following protection tube 4 and is threaded; last protection tube 3 is connected with mouth body 1 by screw thread, and insert in pilot jet 7 centre bores following protection tube 4 bottoms.
Described mouth body 1 material therefor comprises zirconia and boron nitride.
Described accessory 2 is processed by high-strength graphite turning.
The described protection tube 3 of going up is processed by high-strength graphite turning with following protection tube 4.
The beneficial effects of the utility model are: use this catheter can make the flow direction of alloy liquid accurate, drop can not sprawled along the catheter bottom surface, is not easy to be stained with on the pilot jet, is not easy to stop up, and protection tube can effectively be protected the stable of liquid stream; Split-type design can be slowed down thermal conduction rate, reduces the extent of damage to the atomizer system, enhances productivity.
