Abstract
The utility model provides a preparation metal powder's dual -purpose supersonic speed atomizing nozzle device of aqueous vapor, including last lid, go up cone, shell and cone down, the center department of wherein going up lid and last cone is the water conservancy diversion passageway, lower cone overlap last cone lower part, form annular gap between lower cone and the last cone, annular gap is lavalle formula pipeline structure, descends cone and last cone relative with the arcwall face respectively promptly, the shell is installed in the outside of last lid cone on and under, the medium admission passage of shell with the annular gap intercommunication. The utility model discloses can highly reach the purpose of adjusting down the size in circumferential weld clearance between cone and the last cone through the lift that clockwise or anticlockwise rotating screw comes control to go up the cone, and then can adjust atomizing medium (gas or liquid water) and through the spray angle and the jet velocity in circumferential weld clearance, owing to be lavalle formula pipeline structure with annular gap, consequently can realize carrying out atomizing work, improvement atomization effect with the mode of supersonic air current.
Description
Technical field
The utility model relates to a kind of water and gas dual-purpose ultrasonic nebulization jet nozzle device preparing metal dust, belongs to metal powder preparation technical field.
Background technology
Traditional restraint-type circumferential weld aerosolization nozzle, gap size and the atomizing medium gas spray angle of its nozzle atomization circumferential weld are relatively-stationary, the metal dust preparing different-grain diameter and granule-morphology mainly carrys out regulating and control by changing the processing parameters such as atomizing medium pressure, the metal bath degree of superheat, and to affect the topmost factor of metal dust granularity be atomizing nozzle device structure, the adjustment of change to metal dust particle diameter and granule-morphology of processing parameter is subject to larger limitation.
Utility model content
For above deficiency, the utility model provides a kind of water and gas dual-purpose ultrasonic nebulization jet nozzle device preparing metal dust, and this atomizing nozzle device by regulating the size in circumferential weld gap between lower cone and upper cone, and then regulates spray angle and jet velocity.
The utility model is implemented by the following technical programs: a kind of water and gas dual-purpose ultrasonic nebulization jet nozzle device preparing metal dust, comprise upper cover body, upper cone, shell and lower cone, wherein upper cover body and upper cone are placed and up and down by screw assembly connection, the center of upper cover body and upper cone is flow-guiding channel, the upper cone bottom that lower cone is enclosed within, annular gap is formed between lower cone and upper cone, described annular gap is Lavalle formula pipeline configuration, and namely lower cone and upper cone are relative with arcwall face respectively; Described shell is arranged on the outside of upper cover body, lower cone and upper cone, and the medium admission passage of shell is communicated with described annular gap.
Between the medium admission passage and annular gap of shell, be provided with the passage of several along the circumferential direction evenly arrangements, passage is arranged on the bossing of upper cone sidepiece.
At the assembly connection place of upper cover body and shell, sealing ring and sealing ring gland are installed.
Compared with prior art, the utility model has following advantage:
1, the adjustable height that the utility model can control upper cone by clockwise or counterclockwise turn screw reaches the object of the size regulating circumferential weld gap between lower cone and upper cone, and then can regulate the spray angle of atomizing medium (gas or liquid water) through circumferential weld gap and jet velocity;
2, owing to being Lavalle formula pipeline configuration by annular gap, therefore can realize carrying out atomization work in the mode of supersonic flow, improve atomizing effect;
3, between the medium admission passage and annular gap of shell, be provided with the passage of several along the circumferential direction evenly arrangements, the atomizing medium flowing through circumferential weld gap can be made even, and then ensure the stable of circumferential weld gap length;
4, the sealing ring installed at the assembly connection place of upper cover body and shell and sealing ring gland, for playing sealing function.
