Description

Technical Field

[0001] This invention relates to the field of metal powder production technology, and in particular to a nickel-based alloy powder preparation apparatus. Background Technology

[0002] Nickel-based alloy powders are widely used in aerospace, energy, chemical and other fields due to their excellent properties. Sieving is a crucial step in the preparation of nickel-based alloy powders, directly affecting the particle size distribution and the quality of the final product.

[0003] Most nickel-based alloy powder screening devices on the market can only process powders in a dry state, and their ability to process wet powders is limited. Because wet nickel-based alloy powders are prone to clumping, clumping increases the overall density and hardness of the powder. Since the screening mesh used for screening powders is designed for screening powders, its strength is not high. When clumped nickel-based alloy powders are poured onto the screening mesh, they can easily cause impact damage to the mesh. Replacing the screening mesh will also have a negative impact on the screening efficiency of nickel-based alloy powders. Summary of the Invention

[0008] At least one vibrating element is installed inside the cylinder.

[0009] As described above, a food processor with an easy-to-replace mixing component has a groove in its bottom shell for holding nickel-based alloy powder. The inner diameter of the groove is the same as the diameter of the sieve. A discharge hopper is fixedly connected to the side wall of the bottom shell. The discharge hopper is connected to the groove, and the side of the discharge hopper that does not contact the bottom shell is inclined downward.

[0010] As described above, in a food processor with an easy-to-replace mixing component, the components of the first and second legs have the same structure and specifications. The second leg includes a connecting frame, a support rod is fixedly connected to one side of the connecting frame, and gaskets are fixedly connected to the upper and lower ends of the support rod.

[0011] As described above, a food processor with an easy-to-replace mixing component includes a sealing element comprising a retaining ring, which is sleeved on the outside of the cylinder and threadedly connected to the cylinder. The height of the retaining ring is greater than the height of the second through groove, and a handle is fixedly connected to the side wall of the retaining ring.

[0012] As described above, in a food processor that facilitates the replacement of mixing components, a discharge pipe is fixedly connected to the bottom of the second hopper, and an electromagnetic valve is installed inside the discharge pipe.

[0013] As described above, in a food processor that facilitates the replacement of the mixing components, the guide is a combination of two cones that are horizontally mirrored with a round bottom. The guide is disposed inside the bottom shell and does not contact the bottom shell or the sieve.

Detailed Implementation

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] Example 1: This example provides a nickel-based alloy powder preparation apparatus, see [link to example]. Figure 1-8 and Figure 10-11It includes a screening mechanism 1 for screening nickel-based alloy powder and a feeding mechanism 2 installed below the screening mechanism 1 for feeding the nickel-based alloy powder upwards.

[0038] The screening mechanism 1 includes a cylinder 11, with a second flange 16 mounted on its top. A cap 161 is fixedly connected to the bottom of the second flange 16, and the cap 161 is fitted over the cylinder 11. Several first supports 15 are fixedly connected to the side wall of the second flange 16. A sleeve 121 is fitted over the cylinder 11, and a first hopper 12 is fixedly connected to the sleeve 121. Several valves 122 are installed at the bottom of the first hopper 12, and the valves 122 are arranged in a circular array in the first hopper. At the bottom of the hopper 12, a bottom shell 14 is fitted over the cylinder 11. The bottom shell 14 has a groove 141 for holding nickel-based alloy powder. The inner diameter of the groove 141 is the same as the diameter of the sieve screen 13. A discharge hopper 142 is fixedly connected to the side wall of the bottom shell 14. The discharge hopper 142 is connected to the groove 141. The side of the discharge hopper 142 that does not contact the bottom shell 14 is inclined downward. A sieve screen 13 is installed on the top of the bottom shell 14. The sieve screen 13 is fitted over the cylinder 11. The inner cavity of the bottom shell 14 is provided with... A guide member 18 is provided, which is sleeved on the outside of the cylinder 11 and threadedly connected to the cylinder 11. The guide member 18 is a combination of two horizontally mirrored cones with rounded bottoms. The guide member 18 is located inside the bottom shell 14 and does not contact the bottom shell 14 or the screening screen 13. A cone-shaped member 114 is fixedly connected to the bottom of the cylinder 11, and a first flange 113 is fixedly connected to the bottom of the cone-shaped member 114. Several first through grooves 111 are opened on the side wall of the cylinder 11. The first through grooves 111 are used to guide the inner cavity of the bottom shell 14. The cylinder 11 is connected to the inner cavity of the cylinder 11. The cylinder 11 has several second through slots 112. The second through slots 112 are located above the conical member 114. The cylinder 11 is covered by a sealing member 17 for sealing the second through slots 112. The sealing member 17 includes a retaining ring 171. The retaining ring 171 is sleeved on the outside of the cylinder 11 and is threaded to the cylinder 11. The height of the retaining ring 171 is higher than the height of the second through slots 112. A handle 172 is fixedly connected to the side wall of the retaining ring 171.

[0039] The feeding mechanism 2 includes a rod 21, which is a hollow structure. A third flange 26, matching the first flange 113, is fixedly connected to the top of the rod 21. Several second supports 22 are fixedly connected to the side wall of the third flange 26. The components of the first support 15 and the second supports 22 have the same structure and specifications. Each second support 22 includes a connecting frame 221. A support rod 223 is fixedly connected to one side of the connecting frame 221. Gaskets 222 are fixedly connected to the upper and lower ends of the support rod 223. Several third through slots 261 are opened on the side wall of the rod 21. The bottom of the rod 21 is fixed... A motor base 231 is fixedly connected to the rod body 21, and a motor is installed inside the motor base 231. The rotor of the motor is fixedly connected to a screw 232. A second hopper 24 is fitted over the rod body 21 and is fixedly connected to the rod body 21. A discharge pipe 241 is fixedly connected to the bottom of the second hopper 24 and an electromagnetic valve is installed inside the discharge pipe 241. A water supply mechanism 25 is installed on the rod body 21. The water supply mechanism 25 includes a hollow ring 251 and a plurality of nozzles 252 are installed on the ring 251. One end of the nozzle 252 is located inside the rod body 21. A water pipe 253 is fixedly connected to the ring 251.

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

[0041] In the specific implementation process, such as Figure 1-8 and Figure 10-11 As shown, during the production of nickel-based alloy powder, the freshly formed nickel-based alloy powder needs to be sieved. When sieving the dry nickel-based alloy powder, only the sieving mechanism 1 is needed. The vibrating element 19 is activated, causing it to vibrate, which in turn drives the cylinder 11 and the sieve screen 13 mounted on the cylinder 11 to vibrate. At this time, the sieving mechanism 1 is ready for sieving. Further, the operator can feed the nickel-based alloy powder to be sieved into the first hopper 12. The valve 122 is opened, and the nickel-based alloy powder flows from the valve 122 to the sieve screen 13. Because the valve 122 is arranged in a ring array at the bottom of the first hopper 12, the nickel-based alloy... The powder falls evenly onto the screening screen 13. The screening screen 13 screens the nickel-based alloy powder with the vibration of the vibrating element 19. The nickel-based alloy powder that meets the specifications will pass through the screening screen 13 and enter the bottom shell 14. The nickel-based alloy powder that does not meet the specifications will remain on the screening screen 13 and then fall into the groove 141 with the vibration. Finally, it will be discharged from the groove 141 through the discharge hopper 142. The nickel-based alloy powder that enters the bottom shell 14 will be guided by the guide element 18 and enter the cylinder 11 through the first channel 111. The nickel-based alloy powder that enters the cylinder 11 will finally be discharged from the cylinder 11 through the second channel 112, thus completing the screening of the nickel-based alloy powder.

[0042] When it is necessary to screen the moist nickel-based alloy powder, rotate the sealing member 17 to move the retaining ring 171 downwards until the retaining ring 171 completely blocks the second channel 112, conveying the moist nickel-based alloy powder into the second hopper 24. The nickel-based alloy powder enters the rod body 21 through the third channel 261, and is further fed into the rod body 21 by the water supply mechanism 25. After entering the rod body 21, the water flow can only flow upwards due to the obstruction of the feeding mechanism 23, which further activates the motor of the feeding mechanism 23. The motor drives the screw 232 to rotate, and the screw 232 drives the nickel-based alloy powder to be conveyed upwards. The combination of the screw 232 and the motor can control the amount of nickel-based alloy powder conveyed upwards. Gold powder is carried upward by the water flow into the cylinder 11 of the screening mechanism 1. The water flow carries nickel-based alloy powder to contact 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 screen 13, which could damage it. The dispersed nickel-based alloy powder continues to move upward with the water flow until it contacts the screening screen 13. Nickel-based alloy powder that meets the specifications continues to move upward through the screening screen 13, while nickel-based alloy powder that does not meet the specifications is blocked below the screening screen 13. The nickel-based alloy powder that passes through the screening screen 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 and collected by the staff. Because the nickel-based alloy powder is slowly sieved through the screening screen 13 from bottom to top with the water flow, it avoids large impacts and excessive local pressure on the screening screen 13, thus preventing damage and extending its service life. This also prevents a decrease in screening efficiency due to screen replacement. After screening, the second channel 112 is opened by turning the sealing part 17, allowing water and non-compliant nickel-based alloy powder remaining in the screening mechanism 1 to be discharged through the second channel 112. After drainage, water continues to be supplied to the screening mechanism 1 to continue rinsing its interior. This rinsing is repeated until the interior of the screening mechanism 1 is clean. When cleaning the feeding mechanism 2, water is supplied to the rod 21, and the screw 232 is rotated forward and backward by the motor to clean its interior.

[0043] Example 2: In Example 1, there is a problem that when the screening mechanism 1 is performing screening, the vibrating element 19 will drive the entire screening mechanism 1 to vibrate, thereby causing the screening mechanism 1 to shift. Therefore, based on Example 1, this example also includes:

[0044] The cylinder 11 includes a connector 115 and a connecting cylinder 116, and a buffer 117 is provided between the connector 115 and the connecting cylinder 116. The buffer 117 is one or a combination of two of the following: a spring and a rubber block.

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

[0046] Example 3: In Example 1, there was a problem that the screening mechanism 1 could only screen nickel-based alloy powder of one size and could not perform multi-stage screening. Therefore, based on Example 1, this example also includes:

[0047] Multiple screening mechanisms 1 can be stacked and combined to form a multi-stage screening mechanism through the connection of the first flange 113 and the second flange 16.

[0048] In the specific implementation process, such as Figure 12 As shown, multiple screening mechanisms 1 can be stacked according to the required screening grades. The sieve mesh 13 of each screening mechanism 1 has a different aperture size, with the top layer having the largest aperture to screen out the largest particles; the apertures decrease as you move down the layers until the minimum particle size requirement is met. Powder passing through the first layer of sieve mesh falls into the next layer of screening mechanism 1, repeating the screening process. Each layer of screening mechanism 1 only allows powder smaller than its sieve mesh aperture to pass through; powder larger than the aperture remains in the current layer. The smallest particle size passes through all screening layers and finally falls into the bottom shell 14 of the bottom layer of screening mechanism 1. The bottom shell 14 of each layer of screening mechanism 1 can collect nickel-based alloy powder within the corresponding size range.

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

[0050] During the production of nickel-based alloy powder, the freshly formed nickel-based alloy powder needs to be sieved. When sieving the dry nickel-based alloy powder, only the sieving mechanism 1 is needed. The vibrating element 19 is activated, causing it to vibrate, which in turn drives the cylinder 11 and the sieve screen 13 mounted on the cylinder 11 to vibrate. At this time, the sieving mechanism 1 is ready for sieving. Further, the operator can feed the nickel-based alloy powder to be sieved into the first hopper 12. The valve 122 is opened, and the nickel-based alloy powder flows from the valve 122 to the sieve screen 13. Because the valve 122 is arranged in a ring array at the bottom of the first hopper 12, the nickel-based alloy powder... The nickel-based alloy powder can fall evenly onto the screening screen 13. The screening screen 13 screens the nickel-based alloy powder with the vibration of the vibrating element 19. The nickel-based alloy powder that meets the specifications will enter the bottom shell 14 through the screening screen 13. The nickel-based alloy powder that does not meet the specifications will remain on the screening screen 13 and then fall into the groove 141 with the vibration. Finally, it will be discharged from the groove 141 through the discharge hopper 142. The nickel-based alloy powder that enters the bottom shell 14 will be guided by the guide element 18 and enter the cylinder 11 through the first channel 111. The nickel-based alloy powder that enters the cylinder 11 will finally be discharged from the cylinder 11 through the second channel 112, thus completing the screening of the nickel-based alloy powder.

[0051] When it is necessary to screen the moist nickel-based alloy powder, rotate the sealing member 17 to move the retaining ring 171 downwards until the retaining ring 171 completely blocks the second channel 112, conveying the moist nickel-based alloy powder into the second hopper 24. The nickel-based alloy powder enters the rod body 21 through the third channel 261, and is further fed into the rod body 21 by the water supply mechanism 25. After entering the rod body 21, the water flow can only flow upwards due to the obstruction of the feeding mechanism 23, which further activates the motor of the feeding mechanism 23. The motor drives the screw 232 to rotate, and the screw 232 drives the nickel-based alloy powder to be conveyed upwards. The combination of the screw 232 and the motor can control the amount of nickel-based alloy powder conveyed upwards. Gold powder is carried upward by the water flow into the cylinder 11 of the screening mechanism 1. The water flow carries nickel-based alloy powder to contact 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 screen 13, which could damage it. The dispersed nickel-based alloy powder continues to move upward with the water flow until it contacts the screening screen 13. Nickel-based alloy powder that meets the specifications continues to move upward through the screening screen 13, while nickel-based alloy powder that does not meet the specifications is blocked below the screening screen 13. The nickel-based alloy powder that passes through the screening screen 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 and collected by the staff. Because the nickel-based alloy powder is slowly sieved through the screening screen 13 from bottom to top with the water flow, it avoids large impacts and excessive local pressure on the screening screen 13, thus preventing damage and extending its service life. This also prevents a decrease in screening efficiency due to screen replacement. After screening, the second channel 112 is opened by turning the sealing part 17, allowing water and non-compliant nickel-based alloy powder remaining in the screening mechanism 1 to be discharged through the second channel 112. After drainage, water continues to be supplied to the screening mechanism 1 to continue rinsing its interior. This rinsing is repeated until the interior of the screening mechanism 1 is clean. When cleaning the feeding mechanism 2, water is supplied to the rod 21, and the screw 232 is rotated forward and backward by the motor to clean its interior.

[0052] In summary, this invention improves the ability of existing nickel-based alloy powder preparation devices to handle wet powders during sieving while achieving free classification of powders.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
