The moving core 25 adopts a non-circular section, and the inner cavity of the sleeve 26 is matched with the moving core 25, so that the moving core 25 does not generate relative rotation when moving inside the sleeve 26. The sleeve 26 is fixedly connected with the driving wheel 9, and an adjusting spring 27 which is wound outside the second output shaft and used for adjusting the position of the driving wheel 9 relative to the driving motor 8 is arranged between the sleeve 26 and the driving motor 8.
The bottom end of the screw shaft 4 is rotatably connected with a shell 7, and the shell 7 comprises an upper shell a and a lower shell b.
The telescopic piece 10 which stretches out and draws back in the vertical direction is fixedly arranged in the shell 7, and the telescopic piece 10 can adopt an electric push rod. The telescopic end of the telescopic piece 10 is fixedly provided with a lifting plate 11, the bottom end of the lifting plate 11 is fixedly provided with a plurality of vertically arranged pistons 12, the pistons 12 are movably sleeved with cylinder sleeves 13, and the cylinder sleeves 13 are provided with inner cavities.
The bottom of the lower shell b is fixedly provided with a plurality of suction pipes 3 along the circumferential direction of the screw shaft 4, the suction pipes 3 are provided with central holes 2, and the central holes 2 face downwards.

Before the preparation, the titanium alloy was heated to a temperature exceeding the melting point thereof to be in a liquid state, and the liquid titanium alloy was placed in a heating bath to be continuously heated. The preparation process can be carried out in an inert gas protection environment or an oxygen-free environment so as to reduce the oxidation speed of the liquid titanium alloy. When the titanium alloy powder is prepared, the driving motor 8 is used for driving the nut 5 to rotate, so that the screw shaft 4 moves downwards, and the screw shaft 4 vertically downwards and does not rotate under the limiting effect of the limiting block 6. The screw shaft 4 drives the shell 7 to move downwards, so that the bottom end of the pumping pipe 3 is inserted into the liquid titanium alloy. The inner space of the central hole 2 and the inner cavity of the cylinder liner 13 form a closed space. The telescopic piece 10 drives the lifting plate 11 to ascend, so that the piston 12 moves upwards, when the piston 12 moves in the cylinder sleeve 13, the air pressure in the cylinder sleeve 13 and the central hole 2 is reduced, and part of liquid titanium alloy enters the central hole 2 under the action of atmospheric pressure.
Then the driving motor 8 drives the nut 5 and the driving wheel 9 to rotate reversely, and the nut 5 drives the screw shaft 4 to move upwards. The screw shaft 4 drives the housing 7 to move upwards, and when the outer ring of the upper housing a contacts with the outer ring of the driving wheel 9, the rotating driving wheel 9 drives the upper housing a to rotate, so that the lower housing b synchronously rotates. The drawing tube 3 on the lower case b rotates, and at the same time, the expansion member 10 is extended, so that the lifting plate 11 is lowered, and the liquid titanium alloy in the center hole 2 is ejected. The liquid titanium alloy ejected from the suction pipe 3 forms small liquid drops, and is thrown towards the outside of the heating pool under the action of centrifugal force, and is cooled and solidified into small balls in the falling process, so that powder is formed.
Wherein the upper casing a continues to move upward after the driving wheel 9 contacts with the upper casing a, so that the driving wheel 9 moves upward synchronously, thereby allowing the moving core 25 to enter the inside of the sleeve 26, and simultaneously allowing the regulating spring 27 to be compressed. When the upper shell a starts to move downwards, the driving wheel 9 is enabled to continuously contact with the upper shell a under the action of the adjusting spring 27, the driving wheel 9 starts to rotate reversely, the friction force between the inverted driving wheel 9 and the upper shell a is utilized to brake the upper shell a, so that the upper shell a does not rotate or the rotating speed is low after the upper shell a is out of contact with the driving wheel 9, namely, the pumping pipe 3 enters into the titanium alloy liquid under the condition of not rotating.
Further, the outer ring of the driving wheel 9 is embedded with a magnetic block, the shell 7 is made of an iron material, and the magnetic block has a large friction force with the shell 7 due to the adsorption effect of the magnetic block on the shell 7, so that the driving wheel 9 can smoothly drive the shell 7 to rotate when the shell 7 ascends, and the shell 7 is decelerated in the descending process of the shell 7.
Further, take out pipe 3 and be the slope setting, and take out pipe 3's bottom to the direction extension of keeping away from annular array central line, take out pipe 3's centre bore 2 outwards extends can make take out pipe 3 department jet droplet have the initial velocity of horizontal direction to the scope of removing the heating pond that can be faster can solve the droplet and fall into the problem of reaction tank again.
Further, the bottom end fixing of the mounting plate 1 is provided with an inflatable member 14, the inflatable member 14 is a telescopic rod, a one-way valve for absorbing gas from the outside is arranged on the telescopic rod, and a reset spring for controlling the telescopic rod to stretch out and draw back is arranged inside the telescopic rod. The inflatable member 14 is connected with an adapter 15 through the rotation of an air pipe, a plurality of branch pipes 16 communicated with the central hole 2 are fixedly arranged on the adapter 15 so as to realize gas input into the pumping pipe 3, and an electromagnetic valve 17 is arranged in the middle section of the branch pipes 16 so as to realize instantaneous emission of gas and unidirectional movement of gas. The air pipe enters the shell 7 from the screw shaft 4, and the shell 7 needs to rotate relative to the screw shaft 4, so that the arranged adapter 15 can ensure that the air can still be conveyed to the suction pipe 3 when the shell 7 rotates, and the air pipe cannot be wound.
When the housing 7 moves upward, the expansion link is pressed, so that the gas in the expansion link is compressed, and the gas pressure in the expansion link is increased. When the telescopic piece 10 drives the piston 12 to move downwards to prepare the injection of the liquid titanium alloy in the pumping pipe 3, the electromagnetic valve 17 is opened, so that high-pressure gas in the telescopic rod instantaneously enters the center hole 2 through the gas pipe, the adapter 15 and the branch pipe 16 to impact the liquid titanium alloy at the bottom of the center hole 2, the injection speed of the liquid titanium alloy is increased, the center hole 2 is cleaned, the blockage of the liquid titanium alloy is avoided, the integrity of the liquid titanium alloy is improved, and the liquid titanium alloy is prevented from being separated into multiple parts due to low injection speed.
After the injection of the liquid titanium alloy is completed, the electromagnetic valve 17 is closed, the return spring drives the telescopic rod to extend when the shell 7 is far away from the mounting plate 1, and gas is acquired from the outside through the one-way valve.

The gas generated by the inflatable member 14 enters the central hole 2, then rapidly passes through the cleaning member and is ejected from the bottom end of the central hole 2, and the cleaning member is synchronously driven to move in the gas moving process. The cleaning member is accelerated by the inertia of the cleaning member and moves toward the bottom end of the central hole 2.
