Abstract
The utility model belongs to the technical field of light alloy atomization devices, and particularly relates to a combined-type liquid guide pipe used in cooperation with a light alloy atomization system. According to the combined-type liquid guide pipe, a nozzle is connected with an accessory, an orifice is an independent component and is fixed to the bottom end of the inside of the nozzle in an interference fit mode, the bottom face of the orifice is provided with an annular boss, and the outside of the lower end of the nozzle is provided with a protection sleeve and is connected with the protection sleeve. When the liquid guide pipe is used in cooperation with a crucible, the flowing direction of alloy liquid can be accurate, and blocking is not prone to occurring. After a split-type design is adopted, the heat conduction speed can be obviously reduced, and accordingly damage of high temperature to an atomizing nozzle system can be reduced and production efficiency is improved.
Description
Technical field
The utility model belongs to light-alloy atomising device technical field, particularly a kind of and the light-alloy atomization system combined type drain pipe using that matches.
Background technology
In prior art, existing catheter is generally as a whole, and fluid guidance port is positioned at bottommost, and baseplane does not have isolating trenches.When aluminium alloy stream has just flowed out fluid guidance port when atomization, will be subject to the interference of high speed atomization air flow, cause liquid stream to be sprawled along catheter bottom surface, be stained with on pilot jet, accumulate to and to a certain degree can stop up afterwards catheter, cause the interruption of atomization process.And the conduction of the heat of integral type drain pipe is very fast, in crucible, the heat of the aluminium alloy of melting is easy to pass on pilot jet by catheter, can greatly shorten the service life of pilot jet.
Utility model content
The purpose of this utility model is that a kind of alloy in lightweight atomization catheter using that mates with crucible will be provided, and uses this catheter can make the flow direction of aluminium alloy accurate, and drop can not sprawled along catheter bottom surface, is not easy to be stained with on pilot jet.Split-type design can slow down thermal conduction rate, reduces the extent of damage to atomizer system, enhances productivity.
With light-alloy atomization system match use a combined type drain pipe, in described combined type drain pipe, mouth body is connected with accessory, head piece is independently parts, and is fixed on mouth body inner bottom by interference fit, described head piece bottom surface arranges a circle boss; Mouth body lower end arranged outside protective casing, and coupled.
Described mouth body is connected with accessory by screw thread.
Described protective casing is connected by insulating sandwich with mouth body.
Described mouth body inside is manhole.
The utility model completes as follows: a kind of combined type drain pipe matching with alloy in lightweight atomization system, the head piece that is characterized in described catheter is independently parts, and be fixed on mouth body inner bottom by interference fit, and there is a circle boss head piece bottom surface.A protective casing of mouth body lower end cover, can also install an insulating sandwich between protective casing and mouth body, can prevent that mouth body from directly contacting with nozzle, thereby reduces the high temperature injury to atomizer system.Mouth body is connected with accessory by screw thread, is installed to the crucible bottom of coupling.
The mouth body of the utility model catheter and head piece material, according to the feature of institute's atomized alloy, can be silicon nitride ceramics sintering, boron nitride turning processing or other exotic material.Accessory and protective casing can be processed by high-strength graphite turning.
The drain mouth body of the utility model catheter is connected with accessory by screw thread, is fixed on the crucible bottom of coupling.
The beneficial effects of the utility model are:
The utility model catheter mates with crucible while use, can make aluminium alloy flow to accurately, is not easy to stop up.Adopt after split-type design, can obviously slow down thermal conduction rate, thereby can reduce the high temperature injury to atomizer system, enhance productivity.
Accompanying drawing explanation
Fig. 1 be the utility model catheter with crucible and atomization system mate schematic diagram;
Fig. 2 is the installation diagram of the utility model catheter.
Number in the figure: 1-mouth body; 2-head piece; 3-insulating sandwich; 4-protective casing; 5-accessory.
The specific embodiment
The utility model provides a kind of and the light-alloy atomization system combined type drain pipe using that matches, and below in conjunction with the drawings and specific embodiments, the utility model is described further.
A kind of and the light-alloy atomization system combined type drain pipe using that matches, in described combined type drain pipe, mouth body 1 is connected with accessory 5, and head piece 2 is independently parts, and being fixed on mouth body 1 inner bottom by interference fit, described head piece 2 bottom surfaces arrange a circle boss; Mouth body 1 lower end arranged outside protective casing 4, and coupled.
Described mouth body 1 is connected with accessory 5 by screw thread.
Described protective casing 4 is connected by insulating sandwich 3 with mouth body 1.
Described mouth body 1 inside is manhole.
Consult Fig. 1, drain nozzle body 1 is connected with accessory 5 by screw thread, is fixedly mounted on crucible bottom, and mouth body 1 has respectively plane contact with accessory 5 and crucible bottom surface, prevents alloy melt leakage, and alloy melt can only flow out from drain head piece 2.Mouth body 1 stretches into part in pilot jet centre bore a protective casing 4, also has an insulating sandwich 3 between protective casing 4 and mouth body 1, slows down the thermal conduction rate between thermalloy melt and pilot jet, can greatly slow down the high temperature injury to atomizer.
Consult Fig. 2, head piece 2 is fixed on the bottom of mouth body 1 by interference fit, and there is a circle boss head piece bottom surface, can avoid alloy liquid to sprawl along bottom surface.Protective casing 4 is enclosed within mouth body 1 lower end, and also has an insulating sandwich 3 between protective casing 4 and mouth body 1, and accessory 5 is connected with mouth body 1 by screw thread, is installed to the crucible bottom of coupling.
