Description

Technical Field

[0002] Pre-alloyed powder is mainly used in the powder metallurgy and additive manufacturing industries. When manufacturing pre-alloyed powder, high-speed centrifugal atomization is generally required. First, the driving source is used to control the high-speed rotation of the atomizing disk, and then the molten metal is dripped to the center of the atomizing disk through a pipe. Finally, centrifugal force is used to tear it into fine droplets. In this process, inert gas is often used to assist in cooling and inhibit oxidation.

[0003] After searching, the existing announcement number CN108723377A discloses a non-ferrous metal pre-alloyed powder manufacturing technology equipment, including a fixed base plate, a support rod is symmetrically provided on the left and right sides of the upper end surface of the fixed base plate, an annular melting box is provided at the position between the left and right support rods, a heating space is provided inside the melting box, a heating plate is fixedly provided at the left end wall of the heating space, a feeding hole is provided at the lower end wall of the heating space, a sieve hole plate is fixedly provided at the upper end of the feeding hole, an atomizing box is provided below the melting box to fit closely with it, and a hydraulic lifting device is provided at the lower end of the atomizing box. In the process of the atomizing box rising to fit with the melting box, the impact force is reduced by the sealing gasket to protect the safety of the device, and the signal emitted by the information source is received by the receiver to determine the position information of the hydraulic box to ensure the safe operation of the device.

[0004] The existing non-ferrous metal pre-alloyed powder manufacturing technology and equipment still have the following defects: (1) The centrifugal atomizer located in the core high-temperature area of ​​the equipment is a core component that is easily damaged and requires maintenance. Traditional fixing methods (such as bolts) are extremely difficult and time-consuming to disassemble in a high-temperature environment, and are easily damaged. Maintenance often requires a long period of downtime and cooling, which greatly affects production efficiency; (2) In traditional inert gas protection centrifugal atomization, a large amount of inert gas (such as argon) used for protection and cooling is usually directly discharged or simply recycled after a single use. This is not only costly, but also cannot play a role in the metal powder feeding process. Summary of the Invention

[0022] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0023] See also Figures 1 to 11 In one embodiment of the present invention, a device for manufacturing nonferrous metal pre-alloyed powder includes: An electromagnetically driven centrifugal mold mechanism 1 includes an electromagnetic driving module 12, a rotor module 13, and a limiting portion 14. The rotor module 13 is disposed in the electromagnetic driving module 12, and the limiting portion 14 is connected to the rotor module 13. The centrifugal atomizing disc 2 has a foot 22 fixedly provided on the back of the centrifugal atomizing disc 2, and the limiting portion 14 can pass through the foot 22; The shell mechanism 3 includes a mesh inner shell 31 and an outer shell 32. A material discharge cavity is provided between the mesh inner shell 31 and the outer shell 32. The electromagnetic driven centrifugal mold mechanism 1 is fixedly provided at the bottom of the mesh inner shell 31. The sealing mechanism 4 includes a lifting portion 41, a molten extrusion tube 42, and a rotating sealing portion 43. The molten extrusion tube 42 is fixedly connected to the rotating sealing portion 43. The rotating sealing portion 43 is rotatably disposed on the surface of the lifting portion 41 and is used to seal the housing mechanism 3. An electromagnetic unlocking module 5 is provided on the surface of the electromagnetic driven centrifugal die mechanism 1 , and the electromagnetic unlocking module 5 is used to control the limiting portion 14 to disengage from the locking pin 22 .

[0024] See also Figure 3 Furthermore, the electromagnetically driven centrifugal mold mechanism 1 also includes a ventilation disc seat 11, the rotor module 13 includes a hollow rotating shaft 131, a rotating shell frame 132 and a positioning groove 133, the electromagnetic driving module 12 is fixedly set on the surface of the ventilation disc seat 11, the hollow rotating shaft 131 is fixedly connected to the rotating shell frame 132, the hollow rotating shaft 131 is rotatably set on the surface of the ventilation disc seat 11, the surface of the rotating shell frame 132 is provided with a positioning groove 133, and the card pin 22 can enter the positioning groove 133.

[0025] See also Figure 3 and Figure 9Furthermore, the limiting portion 14 includes a limiting block 141 and a spring 142. The limiting block 141 passes through the rotating shell frame 132. The spring 142 is connected between the limiting block 141 and the rotating shell frame 132. The limiting block 141 can pass through the limiting hole on the surface of the clamping foot 22. The limiting block 141 is made of metal.

[0026] See also Figure 9 Furthermore, the electromagnetic unlocking module 5 includes an electromagnet 51 and a bracket 52. The electromagnet 51 is fixedly arranged on the surface of the bracket 52, and the bracket 52 is fixedly arranged on the surface of the ventilation disc seat 11. After being energized, the electromagnet 51 can control the limit block 141 to disengage from the clamping foot 22.

[0027] In an embodiment of the present invention, the electromagnetic drive module 12 is used to directly drive the rotor module 13. Compared with the traditional centrifugal atomization that often uses a motor to drive the atomizing disk through a transmission shaft, the mechanical transmission mechanism is eliminated, the vibration and pollution risks are reduced, the structure is more compact, and the efficiency is higher. The quick installation / disassembly mechanism based on elastic clamping and electromagnetic decoupling can be used. When installing, the clamping foot 22 of the atomizing disk is aligned with the positioning groove 133 and pressed down. The built-in spring 142 automatically pops the limit block 141 into the limit hole on the clamping foot 22 to complete the locking; when disassembling, the electromagnet 51 is energized, and the limit block 141 is forced out of the limit hole by the principle of magnetic repulsion. At this time, the atomizing disk can be directly removed, realizing tool-free, fast, cold (or short-term shutdown) disassembly and assembly of the centrifugal atomizing disk 2. This greatly shortens maintenance time, improves equipment utilization and production continuity, and especially avoids the inconvenience and risk of mechanical operation at high temperatures.

[0028] Installation and maintenance method: During installation, first align the card foot 22 of the centrifugal atomizing disk 2 with the positioning groove 133, and then the user directly presses down the centrifugal atomizing disk 2. According to the elastic card connection principle commonly used in the prior art, the spring 142 can automatically bounce the limit block 141 into the limit hole on the surface of the card foot 22, and then use the telescopic part 411 to control the sealing cover 431 to seal the shell mechanism 3; during maintenance, first use the telescopic part 411 to control the sealing cover 431 to separate from the shell mechanism 3, and then control the electromagnet 51 to be energized. After being energized, the electromagnet 51 uses the principle of magnetic repulsion to control the limit block 141 to separate from the limit hole on the surface of the card foot 22. At this time, the centrifugal atomizing disk 2 can be directly taken out, which has the characteristics of easy disassembly and maintenance.

[0029] See also Figure 8 In one embodiment of the present invention, the lifting portion 41 includes a telescopic member 411 and a base plate 412 , and the base plate 412 is fixedly connected to the movable end of the telescopic member 411 .

[0030] See also Figure 8 and Figure 10Furthermore, the rotating sealing portion 43 includes a sealing cover 431, a central sleeve 432, a driving portion 433 and a crushing blade 434. The central sleeve 432 and the crushing blade 434 are fixedly connected to the sealing cover 431. The central sleeve 432 is rotatably arranged on the surface of the substrate 412. The molten extrusion tube 42 is sleeved in the central sleeve 432. The driving portion 433 is fixedly connected to the substrate 412. The driving portion 433 is used to control the rotation of the central sleeve 432.

[0031] In an embodiment of the present invention, a transmission gear is fixedly provided on the surface of the central sleeve 432, the driving part 433 is connected to the transmission gear, the telescopic part 411 is a hydraulic telescopic rod, and the fixed end of the telescopic part 411 is fixedly connected to the device casing, and the device casing is an atomization box or an atomization hood.

[0032] See also Figure 5 and Figure 6 In one embodiment of the present invention, a thread groove 21 and an air hole 23 are provided on the front of the centrifugal atomizing disk 2, and a first cup-shaped cover 24 is fixedly provided on the back of the centrifugal atomizing disk 2. The angle between the axis of the air hole 23 and the surface of the centrifugal atomizing disk 2 is 15° or 20°. Several annular air holes 23 are connected to the first cup-shaped cover 24, and one end of the hollow rotating shaft 131 is connected to the straight pipe end of the first cup-shaped cover 24.

[0033] See also Figure 10 and Figure 11 Furthermore, the shell mechanism 3 also includes a blanking plate 34 and an air guide tube 35. The blanking plate 34 is fixedly arranged on the outside of the mesh inner shell 31. The other end of the hollow rotating shaft 131 is rotatably connected to the air guide tube 35. The air guide tube 35 is connected to the argon gas conveying equipment. The shell mechanism 3 also includes a second cup-shaped cover 33. The second cup-shaped cover 33 is fixedly arranged at the bottom of the mesh inner shell 31. The second cup-shaped cover 33 can be connected to the argon gas conveying equipment.

[0034] In an embodiment of the present invention, the argon gas conveying equipment air guide pipe 35, the hollow rotating shaft 131 and the plurality of annularly distributed air holes 23 form an argon gas curtain in the central area of ​​the upper surface of the atomizing disk. On the one hand, the gas curtain directly forms a local high-concentration inert zone where the melt is spread and thrown out, effectively inhibiting oxidation and accelerating the cooling and solidification of the molten droplets. On the other hand, the argon gas diffuses radially under the action of centrifugal force to form a high-speed airflow, which actively impacts the unstable liquid filaments or droplets thrown out from the edge of the disk. The annularly distributed crushing blades 434 are located downstream or in a radial position of the gas curtain impact path. The liquid filaments / droplets impacted and broken by the argon gas flow then collide with the rotating or stationary crushing blades 434, and forced secondary physical crushing occurs. It should be noted that when it is necessary to produce metal powder with a smaller particle size, the driving part 433 can be used to control the rotation of the sealing cover 431 and the crushing blades 434; otherwise, the crushing blades 434 are kept stationary, and the stationary crushing blades 434 can still play a crushing role to a certain extent. This solution expands the role of the inert shielding gas into a power source that actively participates in the crushing process, and cleverly cooperates with the physical crushing blades 434 to significantly improve the output rate of fine powder and the uniformity of the powder.

[0035] Pre-alloyed powder manufacturing method: first, the electromagnetic drive module 12 is used to control the high-speed rotation of the rotor module 13, and then the molten metal enters the center position of the upper surface of the centrifugal atomizing disk 2 through the molten extrusion tube 42. Under the action of centrifugal force, the melt spreads into a thin liquid film on the disk surface and is thrown out along the edge of the disk to form unstable liquid filaments. Finally, the liquid filaments break into droplets. The argon delivery equipment forms an argon gas curtain on the upper surface of the centrifugal atomizing disk 2 through the air guide tube 35, the hollow rotating shaft 131 and a plurality of annular air holes 23. On the one hand, the argon gas curtain can inhibit oxidation and accelerate cooling to form metal powder. On the other hand, it can enable the argon gas to diffuse radially under the action of centrifugal force, thereby achieving the purpose of secondary collision with liquid filaments or droplets. The collided liquid filaments or droplets can be secondary crushed by the annularly distributed crushing blades 434, so that metal powder with smaller particle size can be obtained. Under the action of centrifugal force, the metal powder enters the blanking plate 34 through the blanking cavity between the mesh inner shell 31 and the outer shell 32.

[0036] See also Figure 4 and Figure 11 In one embodiment of the present invention, the electromagnetically driven centrifugal mold mechanism 1 further includes turbine blades 15 , which are fixedly disposed on the surface of the hollow rotating shaft 131 , and are distributed between the ventilation disc seat 11 and the second cup-shaped cover 33 .

[0037] See also Figure 7 and Figure 11 Furthermore, the rotary sealing portion 43 further includes a scraper 435, the sealing cover 431 is fixedly connected to the scraper 435, and the scraper 435 is in sliding contact with the surface of the mesh inner shell 31. In the embodiment of the present invention, the turbine blades 15 that rotate at high speed following the hollow shaft 131 are arranged below the atomizing disk. The rotating turbine blades 15 generate negative pressure, which can actively suck the used argon gas flow from the upper surface of the centrifugal atomizing disk 2. The sucked-away airflow carries part of the heat and the ultrafine powder that may be entrained, and passes through the feeding cavity between the inner shell and the outer shell 32, the mesh inner shell 31 (for filtering powder, the ventilation disk seat 11 and the second cup-shaped cover 33 in sequence, and finally enters the argon gas conveying equipment to filter and remove impurities (remove ultrafine powder), cool and adjust the pressure of the returned airflow, and then re-deliver it to the air guide pipe 35 forms an air curtain, which not only realizes the closed-loop recycling of argon, but also drives the metal powder to flow in an orderly manner, preventing it from accumulating and adhering to the cavity wall at high temperature, ensuring that the powder falls smoothly to the discharge plate 34, reducing the risk of blockage and oxidation. When the scraper 435 rotates following the sealing cover 431, it can also automatically clean the powder adhering to the surface of the mesh inner shell 31, further reducing the risk of blockage, and when the circulating airflow flows around the electromagnetic drive module 12, it can provide it with forced convection heat dissipation, effectively solving the heating problem caused by high-speed electromagnetic drive, and significantly improving the life and operation stability of the equipment.

[0038] To sum up, the present application integrates electromagnetic drive, centrifugal atomization, pneumatically assisted secondary crushing, inert gas closed-loop circulation cooling and intelligent rapid maintenance mechanism, which not only realizes the tool-free and quick disassembly and assembly of the centrifugal atomization disk 2, but also significantly improves the output rate of fine powder and the uniformity of the powder. It can also drive the metal powder to flow in an orderly manner to prevent it from accumulating and sticking at high temperatures, and has the characteristics of easy maintenance and high powder quality.
