The screening mesh used for screening is not strong because it needs to be used to screen powder. When the agglomerated nickel-based alloy powder falls on the screening mesh, it is easy to cause impact damage to the screening mesh.

[0039] The feeding mechanism 2 includes a rod body 21, which is a hollow structure. The top of the rod body 21 is fixedly connected to a third flange 26 matching the first flange 113.

[0040] At least one vibrating member 19 is installed in the cylinder 11. The vibrating member 19 is a combination of one or more of an ultrasonic generator, an electromagnetic vibrator, and an eccentric rotating mass vibrator.

[0041] In the specific implementation process, Figure 1-8 and Figure 10-11 As shown, during the production process of nickel-based alloy powder, it is necessary to screen the newly formed nickel-based alloy powder. When the dried nickel-based alloy powder needs to be screened, only the screening mechanism 1 needs to be used, and the vibrating member 19 is started. The vibrating member 19 vibrates, thereby driving the cylinder 11 and the screening net 13 installed on the cylinder 11 to vibrate. At this time, the screening mechanism 1 is ready for screening. Further, the staff can transport the nickel-based alloy powder to be screened into the first hopper 12, open the valve 122, and the nickel-based alloy powder flows from the valve 122 to the screening net 13. Since the valve 122 is arranged in an annular array at the bottom of the first hopper 12, the nickel-based alloy The powder can evenly fall onto the screening mesh 13, and the screening mesh 13 screens the nickel-based alloy powder as the vibrating member 19 vibrates. The nickel-based alloy powder that meets the specifications will pass through the screening mesh 13 and enter the bottom shell 14, while the nickel-based alloy powder that does not meet the specifications will remain on the screening mesh 13, and then fall into the groove 141 as the vibration occurs, and finally be discharged from the groove 141 through the discharge hopper 142. The nickel-based alloy powder that enters the bottom shell 14 is guided by the guide member 18 and then enters the cylinder 11 through the first through groove 111. The nickel-based alloy powder that enters the cylinder 11 is finally discharged from the cylinder 11 through the second through groove 112, thereby completing the screening of the nickel-based alloy powder.

[0042] When the wet nickel-based alloy powder needs to be screened, the sealing member 17 is rotated to move the baffle ring 171 downward until the baffle ring 171 completely blocks the second through groove 112, and the wet nickel-based alloy powder is transported into the second hopper 24, and the nickel-based alloy powder enters the rod body 21 through the third through groove 261, and water is further transported into the rod body 21 through the water supply mechanism 25. After the water enters the rod body 21, it can only flow upward due to the obstruction of the feeding mechanism 23, and the motor of the feeding mechanism 23 is further started, and the motor drives the screw 232 to rotate, and the screw 232 drives the nickel-based alloy powder to be transported upward. The combination of the screw 232 and the motor can control the amount of nickel-based alloy powder transported upward, and the amount of nickel-based alloy powder transported upward is controlled. The gold powder is carried by the upward flowing water into the cylinder 11 of the screening mechanism 1. The water flow brings the nickel-based alloy powder into contact with the guide 18. The guide 18 disperses the nickel-based alloy powder to prevent the metal powder from being concentrated in one place and causing excessive pressure on the screening mesh 13 and causing damage. The dispersed nickel-based alloy powder continues to move upward with the water flow until it contacts the screening mesh 13. The nickel-based alloy powder that meets the specifications continues to move upward through the screening mesh 13, and the nickel-based alloy powder that does not meet the specifications is blocked under the screening mesh 13. The nickel-based alloy powder that passes through the screening mesh 13 will eventually flow into the groove 141 with the water flow due to gravity, and finally be discharged from the screening mechanism 1 through the discharge hopper 142 to be collected by the staff. Since the nickel-based alloy powder is screened slowly through the screening net 13 from bottom to top along with the water flow, it will not cause a large impact and excessive local pressure on the screening net 13, thus avoiding damage to the screening net 13, extending the service life of the screening net 13, and avoiding the reduction of the screening efficiency of the nickel-based alloy powder due to the replacement of the screening net 13. After the screening is completed, the second through slot 112 is opened by twisting the plugging member 17, so that the water remaining in the screening mechanism 1 and the nickel-based alloy powder that does not meet the specifications are discharged from the screening mechanism 1 through the second through slot 112. After the water flow is discharged, the water flow continues to be delivered to the screening mechanism 1, and the inside of the screening mechanism 1 continues to be flushed. After flushing, it continues to be discharged, and the inside of the screening mechanism 1 is cleaned through multiple flushing. When cleaning the feeding mechanism 2, water flow is delivered to the rod body 21, and the screw 232 is driven by the motor to rotate forward and reverse to achieve cleaning of the inside of the rod body 21.

[0043] Embodiment 2: In Embodiment 1, there is still a problem that when the screening mechanism 1 is screening, the vibrating member 19 will drive the entire screening mechanism 1 to vibrate, thereby causing the screening mechanism 1 to move. Therefore, based on Embodiment 1, this embodiment also includes:

[0044] The cylinder body 11 comprises a connector 115 and a connector cylinder 116, and a buffer 117 is arranged between the connector 115 and the connector cylinder 116. The buffer 117 is a spring, a rubber block, or a combination of the two.

[0045] In the specific implementation process, Fig. 9 As shown, when the screening mechanism 1 is working, the vibration generated by the vibrating member 19 will be absorbed and slowed down by the buffer member 117, preventing the vibration from being transmitted to the first support leg 15, thereby reducing the impact of the vibration on the entire device and avoiding the problem of displacement of the screening mechanism 1.

[0046] Embodiment 3: In Embodiment 1, there is still a problem that the screening mechanism 1 can only screen one size of nickel-based alloy powder and cannot perform multi-stage screening. Therefore, based on Embodiment 1, this embodiment also includes:

[0047] A plurality of screening mechanisms 1 can be stacked up and down by connecting the first flange 113 with the second flange 16 to form a multi-stage screening mechanism.

[0048] In the specific implementation process, Fig.12 As shown, multiple screening mechanisms 1 can be stacked according to the required screening level. The aperture size of the screening mesh 13 of each screening mechanism 1 is different. The aperture of the topmost screening mesh is the largest and is used to screen out the largest particles. The aperture of the screening mesh is smaller as it goes down until the minimum particle size requirement is reached. The powder passing through the first layer of screening mesh will fall into the next layer of screening mechanism 1, and the above screening process will be repeated. Each layer of screening mechanism 1 only allows powders smaller than the aperture of its screening mesh to pass through, and powders larger than the aperture will stay in the current layer. The powder of the smallest size will pass through all screening layers and eventually fall into the bottom shell 14 of the bottom screening mechanism 1. The bottom shell 14 of each layer of screening mechanism 1 can collect nickel-based alloy powders of the corresponding size range.

[0049] Specifically, the working principle of the present invention is as follows:

[0050] In the production process of nickel-based alloy powder, it is necessary to screen the newly formed nickel-based alloy powder. When the dried nickel-based alloy powder needs to be screened, only the screening mechanism 1 needs to be used, and the vibrating member 19 is started. The vibrating member 19 vibrates, thereby driving the cylinder 11 and the screening net 13 installed on the cylinder 11 to vibrate. At this time, the screening mechanism 1 is ready for screening. Further, the staff can transport the nickel-based alloy powder to be screened into the first hopper 12, open the valve 122, and the nickel-based alloy powder flows from the valve 122 to the screening net 13. Since the valve 122 is arranged in an annular array at the bottom of the first hopper 12, the nickel-based alloy powder The nickel-based alloy powder can evenly fall onto the screening mesh 13, and the screening mesh 13 will screen the nickel-based alloy powder as the vibrating member 19 vibrates. The nickel-based alloy powder that meets the specifications will pass through the screening mesh 13 and enter the bottom shell 14, while the nickel-based alloy powder that does not meet the specifications will remain on the screening mesh 13, and then fall into the groove 141 as the vibration occurs, and finally be discharged from the groove 141 through the discharge hopper 142. The nickel-based alloy powder that enters the bottom shell 14 is guided by the guide member 18 and then enters the cylinder 11 through the first through groove 111. The nickel-based alloy powder that enters the cylinder 11 is finally discharged from the cylinder 11 through the second through groove 112, thereby completing the screening of the nickel-based alloy powder.

[0051] When the wet nickel-based alloy powder needs to be screened, the sealing member 17 is rotated to move the baffle ring 171 downward until the baffle ring 171 completely blocks the second through groove 112, and the wet nickel-based alloy powder is transported into the second hopper 24, and the nickel-based alloy powder enters the rod body 21 through the third through groove 261, and water is further transported into the rod body 21 through the water supply mechanism 25. After the water enters the rod body 21, it can only flow upward due to the obstruction of the feeding mechanism 23, and the motor of the feeding mechanism 23 is further started, and the motor drives the screw 232 to rotate, and the screw 232 drives the nickel-based alloy powder to be transported upward. The combination of the screw 232 and the motor can control the amount of nickel-based alloy powder transported upward, and the amount of nickel-based alloy powder transported upward is controlled. The gold powder is carried by the upward flowing water into the cylinder 11 of the screening mechanism 1. The water flow brings the nickel-based alloy powder into contact with the guide 18. The guide 18 disperses the nickel-based alloy powder to prevent the metal powder from being concentrated in one place and causing excessive pressure on the screening mesh 13 and causing damage. The dispersed nickel-based alloy powder continues to move upward with the water flow until it contacts the screening mesh 13. The nickel-based alloy powder that meets the specifications continues to move upward through the screening mesh 13, and the nickel-based alloy powder that does not meet the specifications is blocked under the screening mesh 13. The nickel-based alloy powder that passes through the screening mesh 13 will eventually flow into the groove 141 with the water flow due to gravity, and finally be discharged from the screening mechanism 1 through the discharge hopper 142 to be collected by the staff. Since the nickel-based alloy powder is screened slowly through the screening net 13 from bottom to top along with the water flow, it will not cause a large impact and excessive local pressure on the screening net 13, thus avoiding damage to the screening net 13, extending the service life of the screening net 13, and avoiding the reduction of the screening efficiency of the nickel-based alloy powder due to the replacement of the screening net 13. After the screening is completed, the second through slot 112 is opened by twisting the plugging member 17, so that the water remaining in the screening mechanism 1 and the nickel-based alloy powder that does not meet the specifications are discharged from the screening mechanism 1 through the second through slot 112. After the water flow is discharged, the water flow continues to be delivered to the screening mechanism 1, and the inside of the screening mechanism 1 continues to be flushed. After flushing, it continues to be discharged, and the inside of the screening mechanism 1 is cleaned through multiple flushing. When cleaning the feeding mechanism 2, water flow is delivered to the rod body 21, and the screw 232 is driven by the motor to rotate forward and reverse to achieve cleaning of the inside of the rod body 21.

[0052] In summary, the present invention improves the existing nickel-based alloy powder preparation device's ability to process wet powder during screening while achieving free classification of the powder.

[0053] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
