Description

Technical Field

[0001] The invention relates to the technical field of metal powder atomization preparation, and in particular to vacuum induction gas atomization equipment for safely preparing metal powder. Background Art

[0002] The powders prepared by metal gas atomization technology have the characteristics of fine particle size, high sphericity, low oxygen content, mass production capability and low cost. It has become the main method for producing high-performance spherical metal and alloy powders. The principle of atomization is to quickly impact the molten metal flow through the air flow, crush the molten metal flow into very fine droplets and quickly condense to obtain fine metal powder.

[0003] When the existing metal atomization device is in use, after the molten metal solution is introduced into the atomization box, the inlet cannot be closed in time. At the same time, during atomization, the exhaust pipe cannot be closed in time after the atomization is completed, resulting in outside air flowing into the atomization box, causing some metal powder in the atomization box to contact with oxygen in the air. When high-temperature atomization is performed in the atomization box, some metal powder inside will cause violent combustion, resulting in the risk of explosion of the atomization box, resulting in low safety of the atomization equipment. At the same time, the metal melt cannot be fully atomized and cooled during the production process, resulting in some metal melt agglomeration, resulting in poor quality of the metal powder after atomization.

[0046] Embodiment 4

[0047] Based on Example 3, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the external cooling water is pumped into the second connecting pipe 67 through the water pump 68, and then the cooling water is passed into the installation pipe 61 through the second connecting pipe 67, and then the installation pipe 61 passes the cooling water into the cooling groove 63 of the cooling funnel 62 to absorb heat and cool the cooling funnel 62, and then the cooling water enters the first drain pipe 64 through the cooling groove 63, and then the first drain pipe 64 enters the second drain pipe 66 through the first connecting pipe 65 to be discharged, so as to realize the circulating cooling of the cooling funnel 62, and at the same time, the atomized metal solution enters the cooling funnel 62. In the funnel 62, the driving mechanism drives the mounting tube 61 and the cooling funnel 62 to rotate at the same time, driving the metal solution entering the cooling funnel 62 to rotate evenly on the cooling funnel 62 to dissipate heat, so that it is fully cooled into powder, reducing the agglomeration of the atomized metal solution, resulting in poor quality of the powder after atomization and cooling. Subsequently, the cooled metal powder is thrown out of the cooling funnel 62 under the action of centrifugal force and discharged into the atomization box 2, thereby achieving sufficient cooling of the atomized metal solution and further improving the preparation quality of the metal powder.

[0048] Embodiment 5

[0049] Based on Example 3, please refer to Figure 4 , Fig. 9 and Fig.10 As shown, the opening and closing mechanism includes a transmission plate 41 slidably connected to the first transmission tube 33, a transmission column 42 slidably connected to the first transmission tube 33 is fixedly connected to one side of the transmission plate 41, a first spring 43 fixedly connected to the first transmission tube 33 is fixedly sleeved on the outer surface of the transmission column 42, one end of the transmission column 42 is fixedly connected to a transmission frame 44 slidably connected to the atomizing box 2, and a closing plate 45 slidably connected to the atomizing nozzle 14 is fixedly connected on the transmission frame 44; the safety explosion-proof mechanism includes an exhaust pipe 51 fixedly connected to the atomizing box 2, a mounting ring 52 is fixedly connected inside the exhaust pipe 51, a connecting rod 53 is fixedly connected inside the exhaust pipe 51, a telescopic rod 54 is fixedly connected to one side of the connecting rod 53, a stopper 55 slidably connected to the mounting ring 52 is fixedly connected to one end of the telescopic rod 54, and a second spring 56 fixedly connected to the stopper 55 is fixedly sleeved on the outer surface of the telescopic rod 54.

[0050] When the molten metal solution is atomized, argon is blown into the first transmission tube 33. At this time, the transmission plate 41 in the first transmission tube 33 moves under the force of the blown argon, driving the transmission plate 41 to move, the transmission plate 41 drives the transmission column 42 to move, the transmission column 42 drives the transmission frame 44 to move, and the first spring 43 is compressed. Then the transmission frame 44 drives the closing plate 45 to move, and the nozzle of the atomizing nozzle 14 is opened. When the atomization is stopped, the blowing of argon is stopped. At this time, the transmission plate 41 is no longer subjected to the blowing force of argon, and then the transmission column 42 moves under the rebound force of the first spring 43, thereby driving the transmission frame 44 and the closing plate 45 to move, so that the closing plate 45 blocks the atomizing nozzle 14 to prevent the outside from Air enters the atomizing box 2. At the same time, during the atomization process, the blown-in atomized argon gas is subsequently discharged through the exhaust pipe 51. A filter is provided at one end of the exhaust pipe 51. At this time, the gas is discharged through the exhaust pipe 51. Subsequently, the gas pushes the block 55 on the exhaust pipe 51 to move the block 55 out of the mounting ring 52. At this time, the second spring 56 and the telescopic rod 54 are stretched to discharge the gas. When the atomization is stopped, the block 55 is no longer subjected to the blowing force of the gas. At this time, the block 55 enters the mounting ring 52 under the pulling force of the second spring 56 to block the mounting ring 52, preventing external gas from entering the atomizing box 2 from the exhaust pipe 51, thereby realizing that the atomizing device effectively prevents external air from entering the atomizing box 2 during the atomization process, thereby greatly improving the safety of the atomizing device production.

[0051] The working principle of the present invention is as follows: the metal is placed into the electromagnetic induction melting mechanism in the melting box 3, and then the electromagnetic induction melting mechanism melts the metal, and the melted metal flows into the atomizing box 2, and then the molten metal liquid is blown and atomized by the vacuum atomizing mechanism in the atomizing box 2, so that it is fully atomized into metal powder. At the same time, during the atomization process, the atomizing box 2 is effectively isolated from oxygen by the safety explosion-proof mechanism to prevent oxygen from entering the atomizing box 2, so that oxygen from entering the atomizing box 2 and mixing the metal powder with oxygen are avoided, and then the risk of violent combustion and explosion occurs under high temperature conditions, thereby greatly improving the safety of the atomizing equipment.

[0052] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
