Technical Field

Background
The metal powder is a main raw material for powder metallurgy, and in modern life, the metal powder as a raw material is rapidly developed in high-tech technical fields such as metal injection molding, 3D printing, laser cladding and the like.
In the conventional metal powder preparation process, the formed metal droplets are crushed and atomized many times during the descent process to prepare the metal powder. In the traditional equipment, a molten steel leakage ladle is directly connected with an atomizing spray disc with a high-pressure water outlet at the bottom. And the top of the air jacket is provided with an air blowing port, and blown inert gas is blown into the space between the atomizing spray disk and the air jacket. Therefore, the phenomenon that the high-pressure water is instantly vaporized into water vapor after meeting the high-temperature metal dropping liquid can be avoided to a great extent. The water vapor containing a small amount of oxygen flows back vertically upwards, and the water vapor also contains a small amount of oxygen, so that the metal powder is oxidized to a certain degree. In industry, the inert gas is often recovered by condensation or directly separated by equipment. However, the first method still has the metal powder oxidized condition because the water removal is not thorough enough, so that the product quality is not high enough. The second method is costly and not conducive to industrial production. Through improving the first technology for the dewatering is more thorough, can be at the cost of control under the prerequisite of assurance quality.

Referring to fig. 5, the feeding device includes a barrel 172, a plurality of partitions 173, and a plurality of motors 174.

The motor 174 is connected to a data terminal 180. The partition 173 and the cartridge 172 are circular in cross-section, and the edge of the partition 173 continuously interferes with the inner wall of the cartridge 172. In this embodiment, the feeding device has two feeding devices, which have the same structure, and includes a first feeding device 170 and a second feeding device 171, which are connected to the first water removing device 150 and the second water removing device 151, respectively.

It will be appreciated that the feed device may also be provided with a nitrogen inlet for displacing the gas from the feed device, thereby ensuring that the solid desiccant 190 remains at a higher activity within the feed device.
Referring to fig. 1 to 5, the working principle of the novel water-gas combined atomization powder making device 100 of the present invention is as follows: the molten steel in the molten steel breakout ladle 110 trickles into the gas jacket 121 and meets the nitrogen gas blown from the gas blowing ports 124, which moves vertically downward together with the molten steel through the middle passage 125 of the spray plate 123 and is atomized by the high-pressure water sprayed from the high-pressure water spray ports 126 while leaving the spray plate 123. The atomized metal droplets, nitrogen and water vapor continue to move vertically downward in the inner layer of the gas jacket 121. The nitrogen blown out from the air blowing port 124 meets the metal droplets in time, so that the metal droplets are prevented from being oxidized by a small amount of oxygen in the water vapor due to the fact that the water vapor reversely, vertically and upwards flows to contact the metal droplets firstly. The nitrogen and water vapor flowing into the atomizing barrel 122 from the gas jacket 121 flow into the condensing chamber 140 from the gas inlet 141 of the condensing chamber 140 through a pipe, and the condensed moisture flows toward the lower end of the atomizing barrel 122 from the liquid outlet 142 of the condensing chamber 140. Nitrogen and a small amount of water vapor enter the first water removal device 150 through the gas outlet 143 of the condensation chamber 140 (with the inlet 153 and outlet 155 of the second water removal device 151 closed). The nitrogen gas from which the water vapor is further removed by the first water removal device 150 is returned to the second bin 129 of the gas jacket 121. The annular baffle 127 is able to divide the nitrogen as evenly as possible over the surface of the annular baffle 127 as the nitrogen flows into the first bin 128 through the vent holes in the annular baffle 127 in the second bin 129. In conclusion, nitrogen can flow back in the closed loop 191 shown by the arrow formed by the gas jacket 121 and the water condensation chamber, and the backflow can effectively utilize the heat of the whole equipment, so that the backflow airflow has certain heat, the energy can be effectively saved, and the formation of the subsequent metal powder is facilitated. The atomized metal droplets are gradually dried in the atomizing barrel 122 to form powder, and the powder is collected in the powder collecting barrel 130. When the solid desiccant 190 in the first water removal device 150 is deactivated, the inlet 153 and the outlet 155 of the first water removal device 150 are closed, the inlet 153 and the outlet 155 of the second water removal device 151 are opened, and the second water removal device 151 enters the working state. At the same time, the slag outlet 154 of the first water removal device 150 is opened and the deactivated solid desiccant 190 is discharged to the first slag storage tank 160. The data terminal 180 controls the nitrogen inlet 157 to be opened and the nitrogen inlet 157 and the slag outlet 154 of the first water removal device 150 to be closed after the gas in the first water removal device 150 and the first slag storage tank 160 is replaced with nitrogen. The feed port is opened while the lowermost horizontal partition 173 is rotated by the motor 174 to introduce a predetermined amount of fresh solid desiccant 190 into the first water removal device 150, and after that, the nitrogen inlet 157 of the first water removal device 150 is closed. Thus, the first water removal device 150 and the second water removal device 151 are alternately used and cyclically regenerated. For the feeding device, the continuous feeding of the quantitative solid dryer is realized by controlling the partition 173 to gradually turn over from bottom to top in sequence. And the data terminal 180 can grasp the replacement time through time control, thereby realizing continuous control and increasing the continuity of the reaction.
In summary, the novel water-gas combined atomization powder making device provided by the invention can thoroughly remove moisture in the inert gas through the water removal device, so that the inert gas can be recycled. In addition, the novel water-gas combined atomization powder making equipment is connected with at least two water removal devices in parallel, and the two water removal devices work alternately, so that the continuous production of the whole process is realized, and the gap reaction caused by the regenerated solid desiccant is avoided; the feeding device can realize quantitative feeding for many times by arranging the partition plate, is favorable for accurate control of the data terminal and is more continuous.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
