Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrode induction melting gas atomization powder production technology, and in particular to an induction heating device with a novel gas atomization three-turn parallel induction coil. Background Technology
[0002] Existing induction heating devices use induction coils made of copper tubing, typically with three turns. However, these coils are prone to uneven distribution, with one side higher than the other. During bar melting, this misalignment causes a deviation in the magnetic field strength generated by the coil. While this achieves bar melting, as the bar shortens and becomes lighter, it is prone to deflection towards the tip, causing molten liquid to drip onto the coil and potentially leading to arcing or breakdown.
[0003] Furthermore, to improve the yield of fine powder, the superheat of the molten droplets needs to be increased. While reducing the diameter of the three turns of the wound coil brings it closer to the bar stock, the magnetic field deviation becomes more significant, and arcing or breakdown of the coil is more likely to occur. However, parallel coils do not have the problem of magnetic field deviation. Even after reducing the diameter of the three turns, the uniformity of the magnetic field is not affected, and the superheat of the molten droplets can be improved more effectively.
[0004] Furthermore, due to the softness of copper, it is difficult to ensure the stability of structural dimensions such as coil turn spacing and three-turn diameter during manufacturing, shipping, and coil installation. Coupled with the inherent characteristic of magnetic induction intensity skew, this further increases the possibility of rod skew during melting, making coil sparking or breakdown problems even more prominent.
[0005] In view of this, this utility model is hereby proposed. Utility Model Content

Moreover, even if the diameter of the induction coil is reduced, its magnetic field will not be affected. In addition, the parallel induction coil is sleeved on the outer surface of the high thermal conductivity ceramic cylinder, which effectively prevents the bar stock from contacting the induction coil.

[0011] Furthermore, the fixing assembly includes a first fixing plate at the upper end, a connecting column in the middle, and a second fixing plate at the lower end. Multiple first circular through holes and second circular through holes are respectively formed on the first and second fixing plates along their respective circumferential directions. The upper end of the connecting column passes through the first circular through hole and is fixed to the first fixing plate. Correspondingly, the lower end of the connecting column passes through the second circular through hole and is fixed to the second fixing plate.

[0012] Furthermore, the alignment component includes a threaded rod, one end of which is fixed to a connecting plate, and the other end passes through the connecting post of the fixing component and is connected to the extrusion plate.

Compared with the traditional coil, this arrangement can prevent the magnetic induction intensity from deflecting, help to concentrate the magnetic induction center, and thus avoid the bar stock from deflecting. Moreover, even if the diameter of the induction coil is reduced, its magnetic field will not be affected. In addition, the parallel induction coil is sleeved on the outer surface of the high thermal conductivity ceramic cylinder, which effectively prevents the bar stock from contacting the induction coil, and also effectively prevents the induction coil from being sparked or broken down.

[0020] 3. The induction heating device with a novel gas-atomized three-turn parallel induction coil provided by this utility model uses an isolation component set in the induction heating chamber to move the high-temperature resistant ceramic spacer vertically up and down to a suitable position inside the first square hole and the second square hole.

Detailed Implementation
[0031] The embodiments of the present invention will be described in detail below with reference to the examples. However, those skilled in the art will understand that the following examples are only for illustrating the present invention and should not be regarded as limiting the scope of the present invention.
[0032] According to an embodiment of the present invention, referring to Figure 1As shown, this utility model discloses an induction heating device with a novel gas-atomizing three-turn parallel induction coil. A feed inlet is located at the center of the upper part of the device. Metal rods enter the induction heating chamber 1 through the feed inlet and reach the high thermal conductivity ceramic cylinder 7 of the liquid collection assembly. The induction heating device includes the induction heating chamber 1, a liquid collection assembly, a fixing assembly, a centering assembly, a melting assembly, and an isolation assembly. The liquid collection assembly, fixing assembly, centering assembly, melting assembly, and isolation assembly are all located within the induction heating chamber 1. A through-slot is formed on the side wall of the induction heating chamber 1. The melting assembly enters the induction heating chamber 1 through the through-slot. The left end of the melting assembly is fixed to the side wall of the induction heating chamber 1 using a slot or thread, thus fixing the melting assembly inside the induction heating chamber 1. The right end of the melting assembly is the induction coil 5, which is placed inside the fixing assembly. A liquid collecting assembly is fixedly connected to the upper end of the inner wall of the induction heating chamber 1. A high thermal conductivity ceramic cylinder 7, located at the lower end of the liquid collecting assembly, passes through the middle of the fixed assembly. A centering assembly is slidably connected to the side of the fixed assembly. An isolation assembly is connected through the centering assembly and the fixed assembly. An installation groove is provided on the inner bottom wall of the induction heating chamber 1. An atomizing spray disc 22 located at the lower end of the induction heating chamber 1 is fixedly connected through the installation groove. A gas distribution ring 23 is fixedly installed on the upper surface of the atomizing spray disc 22. The upper end of the gas distribution ring 23 is fixedly connected to the lower end of the fixed assembly.
[0033] According to an embodiment of the present invention, in accordance with Figure 2 As shown, the left end of the melting assembly is an external block 2, and the right end is connected to an induction coil 5 via an inlet and an outlet water connection pipe. The external block 2 is fixedly connected to the through groove. Connecting blocks 4 are fixed to the inlet and outlet water connection pipes respectively. The connecting blocks 4 are fixed to the inner wall of the external block 2 by copper bolts 3. An inlet pipe hole and an outlet pipe hole are opened in the middle of the external block 2. The inlet pipe passes through the inlet pipe hole and connects to the inlet pipe set outside the induction heating chamber 1. The outlet pipe passes through the outlet pipe hole and connects to the outlet pipe set outside the induction heating chamber 1. The induction coil 5 has three turns, which are parallel to each other. Each turn of the induction coil 5 has an outlet end and an inlet end respectively. Pipe connectors are installed in the middle of both the inlet and outlet pipes. The left end of the pipe connector is connected to one inlet pipe and one outlet pipe, and the right end of the pipe connector is connected to three inlet pipes and three outlet pipes. The three inlet pipes are connected to the inlet end of the three-turn induction coil 5, and the three outlet pipes are connected to the outlet end of the three-turn induction coil 5.
[0034] Specifically, the inlet pipe connects to the external water supply system, and the outlet pipe connects to the external cooling water system. Cooling water is introduced into the inlet pipe and flows into the induction coil 5, carrying away the heat generated within the coil. The heated cooling water then flows into the external cooling water system through the outlet pipe. The external block 2 also has an external power supply device that powers the induction coil 5. Specifically, a copper plate is installed on the outside of the external block 2, connected to the power supply device via wires. The copper plate is connected to the connecting block 4 on the external block 2. The connecting block 4 is connected to the induction coil via the outlet and inlet pipes. Since the copper plate, connecting block 4, outlet and inlet pipes, and induction coil 5 are all made of conductive metal, specifically copper, electricity can be conducted to the induction coil 5. To separate the outlet and inlet pipes within the external block 2 and prevent short circuits caused by contact, an insulating layer is installed between them. The cooling water flowing in the outlet connection pipe is deionized water, which is non-conductive.
[0035] When the induction coil 5 is energized, it generates a magnetic field. When the metal rod approaches the induction coil 5, the presence of the magnetic field induces eddy currents within the metal rod, causing its temperature to rise and melting. Compared to traditional coils, the induction coil 5 features three parallel turns, which prevents magnetic induction intensity from becoming skewed, concentrating the magnetic field center and preventing the metal rod from becoming misaligned. Furthermore, the reduced diameter of the parallel-arranged induction coil 5 does not affect its magnetic field. Cooling water flows through the induction coil 5. Since the induction coil 5 is made of copper tubing, which has excellent thermal conductivity, it can quickly dissipate heat. An insulating layer is wrapped around the outer surfaces of the induction coil, the outlet water connection pipe, the inlet water connection pipe, the external connecting block 2, and the connecting block 4. This prevents current leakage and short circuits, ensuring the safety of the device and protecting the induction coil 5 from external environmental influences, achieving the cooling purpose. The flow of cooling water carries away the heat generated within the induction coil 5, preventing overheating and affecting its performance.
[0036] According to an embodiment of the present invention, in accordance with Figure 3 In the indicated direction, the liquid collection assembly includes a funnel 6, the outer wall of which is fixedly connected to the inner wall of the induction heating chamber 1. A high thermal conductivity ceramic cylinder 7 is fixedly connected to the middle of the lower surface of the funnel 6. The lower end of the high thermal conductivity ceramic cylinder 7 passes through the induction coil 5. A dripping plate 8 is installed at the funnel opening in the middle of the upper surface of the funnel 6. The lower end of the dripping plate 8 is sleeved on the inner wall of the high thermal conductivity ceramic cylinder 7.
[0037] Furthermore, the induction coil 5 is sleeved on the outer surface of the high thermal conductivity ceramic cylinder 7 to prevent the metal rod from contacting the parallel induction coil 5, which could cause it to spark or break down. The drip tray 8 can limit the metal rod to prevent it from completely passing through the high thermal conductivity ceramic cylinder 7. At the same time, it reduces the size of the molten droplets formed after melting, which facilitates the increase of the superheat of the molten droplets and thus increases the fine powder content in the atomized powder.
[0038] According to an embodiment of the present invention, in accordance with Figure 4-6 As shown in the diagram. First, the fixing assembly includes a first fixing plate 9 at the upper end, a connecting post 10 in the middle, and a second fixing plate 11 at the lower end. Multiple first circular through holes and second circular through holes are respectively formed on the first fixing plate 9 and the second fixing plate 11 along their respective circumferential directions. The upper end of the connecting post 10 passes through the first circular through hole and is fixed to the first fixing plate 9 by a fixing nut 12. Correspondingly, the lower end of the connecting post 10 passes through the second circular through hole and is fixed to the second fixing plate 11 by a fixing nut 12. A first square hole is formed in the middle of the connecting post 10, and threaded holes and sliding grooves are formed at both the upper and lower ends of the connecting post 10. The fixing nut 12 allows the device to be disassembled in multiple places, facilitating the overall assembly of the device and the placement of the induction coil 5 inside the fixing assembly.
[0039] Specifically, according to the appendix Figure 4 As shown, five first circular through holes and five second circular through holes are respectively opened on the first fixed disk 9 and the second fixed disk 11. Correspondingly, five connecting posts 10 are installed between the first fixed disk 9 and the second fixed disk 11. It should be noted that the number of circular through holes opened on the first fixed disk 9 and the second fixed disk 11 can be set according to actual needs, and the number of circular through holes determines the number of connecting posts 10 set in the middle. The middle part of the connecting post 10 is a square frame with a first square hole. The upper and lower ends of the square frame are cylinders, and threaded holes and sliding grooves are opened on the cylinders at both ends. More specifically, the upper cylinder has a threaded hole at the top and a sliding groove at the bottom; while the lower cylinder has a sliding groove at the top and a threaded hole at the bottom. Circular holes are opened in the middle of the first fixed disk 9 and the second fixed disk 11, and the high thermal conductivity ceramic cylinder 7 can pass through the circular holes on the first fixed disk 9 and the second fixed disk 11 to reach the upper end of the gas distribution ring 23.
[0040] According to an embodiment of the present invention, in accordance with the appendix Figure 5As shown, each connecting post 10 corresponds to a set of alignment components. Each alignment component includes a threaded rod 13, one end of which is fixed to a connecting plate 16, and the other end passing through a threaded hole in the connecting post 10 and threadedly connected to a push plate 15. The connecting plate 16 also has one end of a measuring rod 17 fixed to it, and the other end of the measuring rod 17 passing through a sliding groove in the connecting post 10 and fixed to the push plate 15. A second square hole is provided in the middle of the push plate 15. A set of alignment components includes one push plate 15, two threaded rods 13, two measuring rods 17, and two connecting plates 16. Each of the two connecting plates 16 has one threaded rod 13 and one measuring rod 17 fixed to it.
[0041] Specifically, the threaded rod 13 and measuring rod 17 located at the top are fixed by a connecting plate 16, which is located outside the connecting post 10. The extrusion plate 15 is located inside the connecting post 10. The threaded rod 13 and measuring rod 17 pass through the threaded hole and sliding groove on the connecting post 10 in sequence and connect to the top of the extrusion plate 15. The measuring rod 17 and threaded rod 13 located at the bottom are fixed by a connecting plate 16, which is located outside the connecting post 10. The extrusion plate 15 is located inside the connecting post 10. The measuring rod 17 and threaded rod 13 pass through the sliding groove and threaded hole on the connecting post 10 in sequence and connect to the bottom of the extrusion plate 15. More specifically, threaded holes corresponding to the threaded rod 13 and sliding grooves corresponding to the measuring rod 17 can be opened above and below the extrusion plate 15. Two fastening nuts 14 are also provided on the threaded rod 13, one fastening nut 14 for fastening to the connecting post 10 and the other fastening nut 14 for fastening to the extrusion plate 15. Under the measuring action of the measuring rod 17, the threaded rod 13 pushes the extrusion plate 15 to move to the periphery of the induction coil 5 and fits against the periphery of the induction coil 5. Then, the threaded rod 14 is tightened to fix the position of the threaded rod 13, so that the center position of the induction coil 5 is aligned with the center of the atomizing spray plate 22 and the center of the metal bar. This ensures that the three turns of the induction coil 5 are in a parallel state, avoids the problem of magnetic induction intensity deviation caused by the change of the diameter of the induction coil 5 during transportation, and thus improves the stability of melting and avoids the deviation of the metal bar.
[0042] According to an embodiment of the present invention, in accordance with the appendix Figure 6As shown, the isolation assembly includes a high-temperature resistant ceramic spacer 18. One end of the high-temperature resistant ceramic spacer 18 is placed between the turns of two adjacent induction coils 5, and the other end passes through the second square hole and the first square hole in sequence, and is then snapped onto the outside of the connecting post 10 by the positioning plate 21. A retaining ring 20 is provided on the high-temperature resistant ceramic spacer 18, and correspondingly, a retaining groove is provided on the inner wall of the positioning plate 21. When the retaining ring 20 is snapped into the retaining groove, the high-temperature resistant ceramic spacer 18 is fixed to the outside of the connecting post 10. A limiting plate 19 is also fixed on the high-temperature resistant ceramic spacer 18, and the upper and lower ends of the limiting plate 19 abut against the lower and upper surfaces of the two adjacent induction coils 5, respectively. When fixing the high-temperature resistant ceramic spacer 18, it is necessary to move the high-temperature resistant ceramic spacer 18 vertically to a suitable position, and then snap the positioning plate 21 onto the outer surface of the retaining ring 20. Combined with the limiting plate 19, the position of the high-temperature resistant ceramic spacer 18 is fixed, thereby supporting the turn spacing of the parallel induction coils 5, and effectively ensuring the structural stability of the induction coils 5, avoiding arcing or breakdown problems of the induction coils 5.
[0043] Specifically, since there are two turn gaps between the three-turn induction coils 5, each connecting post 10 corresponds to two sets of isolation components.
[0044] According to an embodiment of the present invention, in accordance with the appendix Figure 7 As shown, an installation groove is provided on the inner bottom wall of the induction heating chamber 1. An atomizing spray disc 22 located at the lower end of the induction heating chamber 1 is fixedly connected through the installation groove. A gas distribution ring 23 is fixedly installed on the upper surface of the atomizing spray disc 22, and the upper end of the gas distribution ring 23 is fixedly connected to the lower end of the fixing assembly. The atomizing spray disc 22 can atomize molten droplets into fine molten droplets through the nozzle, which facilitates the improvement of heat exchange efficiency. The gas distribution ring 23 evenly distributes the gas into the heating chamber, making the gas flow in the heating chamber more uniform.
[0045] An atomizing chamber 24 is fixedly connected to the lower surface of the induction heating chamber 1. A connecting pipe 25 is fixedly connected to the lower surface of the atomizing chamber 24. Inside the atomizing chamber 24, the solution is atomized into fine particles by high-pressure gas injection, and then enters the separator 26 through the connecting pipe 25. One end of the connecting pipe 25 is fixedly connected to the separator 26, and a powder collection bin 27 is fixedly connected to the lower surface of the separator 26. In the separator 26, the atomized solution generates centrifugal force through rotating airflow, causing solid particles to settle towards the outer wall under the combined action of gravity and centrifugal force, and enter the powder collection bin 27, thereby achieving the separation of solids and gases.
[0046] The working principle of the heating device of this utility model is as follows: First, the melting component is installed into the induction heating chamber 1. At this time, the center of the induction coil 5 and the high thermal conductivity ceramic cylinder 7 are aligned. The second fixing plate 11 is placed on the upper surface of the gas distribution ring 23. Then, the lower part of the outer surface of the high thermal conductivity ceramic cylinder 7 passes through the middle part of the second fixing plate 11. The top end of the connecting column 10 passes through the first circular through hole, and then its lower end passes through the second circular through hole on the second fixing plate 11. The fixing nut 12 is used to fix it. Next, under the measuring action of the measuring rod 17, the threaded rod 13 pushes the extrusion plate 15 to move to the periphery of the induction coil 5 and fits against the periphery of the induction coil 5. Then, the threaded nut 14 is tightened to fix the position of the threaded rod 13, so that the center position of the induction coil 5 is aligned with the center of the atomizing spray plate 22 and the center of the metal rod. At the same time, the high-temperature resistant ceramic spacer 18 is moved up and down to a suitable position inside the square hole. Then, the positioning plate 21 is snapped onto the outer surface of the retaining ring 20, and the position of the high-temperature resistant ceramic spacer 18 is fixed by the limiting plate 19, thereby supporting the turn spacing of the parallel induction coils 5. Next, connecting block 4 is connected to external block 2 via copper bolts 3. External block 2 is connected to an external water supply system and power supply device, allowing cooling water to pass through its center and powering the induction coil 5. The induction coil 5 generates a magnetic field. When the metal rod enters from the feed inlet and reaches the high thermal conductivity ceramic cylinder 7 and approaches the induction coil 5, eddy currents are generated inside the metal rod due to the magnetic field, thereby raising the temperature of the metal rod and melting it. Finally, the solution is atomized into fine particles by high-pressure gas injection inside the atomization chamber 24, and then enters the separator 26 through the connecting pipe 25. The centrifugal force generated by the rotating airflow causes the solid particles to settle towards the outer wall under the combined action of gravity and centrifugal force, entering the powder collection bin 27, thus achieving the separation of solids and gases.
