Description

Technical Field

[0001] The invention relates to the technical field of electrode induction melting gas atomization powder making, in particular to an induction heating device with a novel gas atomization three-turn parallel induction coil. Background Art

[0002] The induction coil of the existing induction heating device is wound by a copper tube, usually with three turns. However, the wound induction coil is prone to one side being high and the other side being low. During the bar melting process, the three-turn coil is skewed, which will cause the magnetic induction intensity generated by the induction coil to be skewed. Although the bar can be melted, when it is melted to the head of the material, the bar becomes shorter and lighter, and the bar is prone to deflection, causing the molten liquid to drip onto the coil, causing the coil to spark or break down.

[0003] In addition, in order to improve the yield of fine powder, the superheat of the molten droplets needs to be increased. If the diameter of the winding coil is reduced by three turns, although it is closer to the bar, the magnetic field deflection will be more significant, and the coil sparking or breakdown problems will also occur more easily. However, parallel coils do not have the problem of magnetic field deflection. Even if the diameter of the three turns is reduced, the magnetic field uniformity will not be affected, and the superheat of the molten droplets can be more effectively increased.

[0004] In addition, due to the softness of copper, it is difficult to ensure that the coil turn spacing and three-turn diameter and other structural dimensions remain stable during the production, delivery and installation of the coil. Coupled with the inherent characteristic of magnetic induction intensity deviation, the possibility of bar deviation during smelting is further increased, making the problem of coil sparking or breakdown more prominent.

[0005] In view of this, this invention is proposed. Summary of the invention

DETAILED DESCRIPTION

[0029] The embodiments of the present invention will be described in detail below with reference to examples, but those skilled in the art will understand that the following examples are only used to illustrate the present invention and should not be construed as limiting the scope of the present invention.

[0030] According to an embodiment of the present invention, referring to Figure 1As shown, an induction heating device with a novel gas atomization three-turn parallel induction coil of the present invention is provided with a feed port at the upper center position, and the metal rod enters the induction heating chamber 1 through the feed port and reaches the high thermal conductivity ceramic cylinder 7 of the liquid collecting component. The induction heating device comprises an induction heating chamber 1, a liquid collecting component, a fixing component, a centering component, a melting component and an isolation component, wherein the liquid collecting component, the fixing component, the centering component, the melting component and the isolation component are all arranged in the induction heating chamber 1. A through groove is provided on the side wall of the induction heating chamber 1, and the melting component enters the interior of the induction heating chamber 1 through the through groove. The left end of the dissolving component is fixed to the side wall of the induction heating chamber 1 by a slot or a thread, that is, the melting component is fixed inside the induction heating chamber 1, and the right end of the melting component is an induction coil 5, which is placed in the fixing component. A liquid collecting component is fixedly connected to the upper end of the inner wall of the induction heating chamber 1, and a high thermal conductivity ceramic cylinder 7 arranged at the lower end of the liquid collecting component passes through the middle of the fixed component. A centering component is slidably connected to the side of the fixed component, and an isolation component is connected through the centering component and the fixed component. A mounting groove is provided on the inner bottom wall of the induction heating chamber 1, and an atomizing spray disc 22 located at the lower end of the induction heating chamber 1 is fixedly connected through the mounting groove. An air dividing ring 23 is fixedly installed on the upper surface of the atomizing spray disc 22, and the upper end of the air dividing ring 23 is fixedly connected to the lower end of the fixed component.

[0031] According to an embodiment of the present invention, Figure 2 In the direction shown, the left end of the melting assembly is an external block 2, and the right end is connected to an induction coil 5 through a water inlet connecting pipe and a water outlet connecting pipe. The external block 2 is fixedly connected in the through groove, and a connecting block 4 is fixed on the water inlet connecting pipe and the water outlet connecting pipe, respectively. The connecting block 4 is fixed to the inner wall of the external block 2 through a copper bolt 3. A water inlet pipe hole and a water outlet pipe hole are opened in the middle of the connecting block 2. The water inlet connecting pipe passes through the water inlet pipe hole to connect to the water inlet pipe set outside the induction heating chamber 1, and the water inlet and outlet connecting pipes pass through the water outlet pipe hole to connect to the water outlet pipe set outside the induction heating chamber 1. The induction coil 5 has three turns, and the three turns of the induction coil 5 are parallel to each other. The two ends of each turn of the induction coil 5 are respectively provided with a water outlet end and a water inlet end. A pipe connector is provided in the middle of the water inlet connecting pipe and the water outlet connecting pipe. The left end of the pipe connector is respectively connected to one water inlet connecting pipe and one water outlet connecting pipe, and the right end of the pipe connector is respectively connected to three water inlet connecting pipes and three water outlet connecting pipes. The three water inlet connecting pipes are respectively connected to the water inlet ends of the three-turn induction coil 5, and the three water outlet connecting pipes are respectively connected to the water outlet ends of the three-turn induction coil 5.

[0032] Specifically, the water inlet connecting pipe is connected to the water supply system outside the device, and the water outlet connecting pipe is connected to the cooling water system outside the device. By passing cooling water into the water inlet connecting pipe, the cooling water flows into the induction coil 5, and the flow of cooling water takes away the heat generated in the induction coil 5. The heated cooling water then flows into the external cooling water system through the water outlet connecting pipe. The external block 2 is also externally connected to a power supply device, which can add power to the induction coil 5. Specifically, a copper plate is arranged on the outside of the external block 2, and the copper plate is connected to the power supply device through an electric wire. The copper plate is connected to the connecting block 4 connected to the external block 2, and the connecting block 4 is connected to the induction coil through the water outlet connecting pipe and the water inlet connecting pipe. Since the copper plate, the connecting block 4, the water outlet connecting pipe, the water inlet connecting pipe and the induction coil 5 are all made of conductive metal materials, specifically copper, the induction coil 5 can be energized by electrical conduction. In order to separate the water outlet connecting pipe and the water inlet connecting pipe located in the external block 2 to avoid the situation where the two collide and cause a current short circuit, an insulating layer is arranged between the water outlet connecting pipe and the water inlet connecting pipe. The cooling water flowing in the water outlet connecting pipe and the water outlet connecting pipe is deionized water, and deionized water is non-conductive.

[0033] When the induction coil 5 is energized to generate a magnetic field, when the metal bar is close to the induction coil 5, due to the existence of the magnetic field, eddy currents are generated inside the metal bar, thereby increasing the temperature of the metal bar and melting the metal bar. Compared with the traditional coil, the induction coil 5 is arranged in three turns in parallel, which can avoid the deflection of the magnetic induction intensity, help to concentrate the magnetic induction center, and prevent the metal bar from being deflected. After the diameter of the parallel induction coil 5 is reduced, it has no effect on its magnetic field. Cooling water is passed through the induction coil 5. Since the induction coil 5 is made of copper tube material, the copper tube material has good thermal conductivity and can quickly dissipate heat. The outer surfaces of the induction coil, the water outlet connecting pipe, the water inlet connecting pipe, the external block 2 and the connecting block 4 are all wrapped with an insulating layer, which can prevent current leakage and short circuit, ensure the safety of the device, and protect the induction coil 5 from being affected by the external environment to achieve the cooling purpose. The flow of cooling water takes away the heat generated in the induction coil 5, preventing the induction coil from affecting its performance due to overheating.

[0034] According to an embodiment of the present invention, Figure 3 In the direction shown, the liquid collecting component includes a funnel 6, the outer wall of the funnel 6 is fixedly connected to the inner wall of the induction heating chamber 1, a high thermal conductivity ceramic tube 7 is fixedly connected to the middle of the lower surface of the funnel 6, the lower end of the high thermal conductivity ceramic tube 7 passes through the induction coil 5, and a drip tray 8 is installed at the funnel mouth in the middle of the upper surface of the funnel 6, and the lower end of the drip tray 8 is sleeved on the inner wall of the high thermal conductivity ceramic tube 7.

[0035] Furthermore, the induction coil 5 is sleeved on the outer surface of the high thermal conductivity ceramic tube 7 to prevent the metal rod from contacting the parallel induction coil 5, causing it to spark or break down, and the drip plate 8 can limit the metal rod to prevent it from completely passing through the high thermal conductivity ceramic tube 7, and at the same time shrink the molten droplets formed after melting, so as to increase the superheat of the molten droplets, thereby increasing the fine powder content in the atomized powder.

[0036] According to an embodiment of the present invention, Figure 4-6 Direction as shown. First, the fixing assembly includes a first fixing disk 9 arranged at the upper end, a connecting column 10 in the middle, and a second fixing disk 11 arranged at the lower end. A plurality of first circular through holes and second circular through holes are respectively provided on the first fixing disk 9 and the second fixing disk 11 along their respective circumferential directions. The upper end of the connecting column 10 passes through the first circular through hole and is fixed to the first fixing disk 9 by a fixing nut 12. Correspondingly, the lower end of the connecting column 10 passes through the second circular through hole and is fixed to the second fixing disk 11 by a fixing nut 12. A first square hole is provided in the middle of the connecting column 10, and threaded holes and sliding grooves are provided at the upper and lower ends of the connecting column 10. The fixing nut 12 makes the device detachable at multiple locations, which is convenient for assembling the device as a whole and for placing the induction coil 5 into the fixing assembly.

[0037] Specifically, according to the attached Figure 4 As shown, 5 first circular through holes and second circular through holes are respectively provided on the first fixed disk 9 and the second fixed disk 11, and correspondingly, 5 connecting columns 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 provided 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 columns 10 provided in the middle. The middle part of the connecting column 10 is a square frame, which is provided with a first square hole. The upper and lower ends of the square frame are cylinders, and threaded holes and sliding grooves are provided on the cylinders at the upper and lower ends. More specifically, a threaded hole is provided above the cylinder at the upper end, and a sliding groove is provided below; while a sliding groove is provided above the cylinder at the lower end, and a threaded hole is provided below. Circular holes are provided 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 in sequence to reach the upper end of the gas dividing ring 23.

[0038] According to an embodiment of the present invention, Figure 5As shown, each connecting column 10 corresponds to a set of centering components, which include: one end of the threaded rod 13 is fixed to the connecting plate 16, and the other end passes through the threaded hole on the connecting column 10 and is threadedly connected to the pushing plate 15. The connecting plate 16 is also fixed with one end of a measuring rod 17, and the other end of the measuring rod 17 passes through the sliding groove of the connecting column 10 and is fixed to the pushing plate 15. A second square hole is opened in the middle of the pushing plate 15. A set of centering components includes a pushing plate 15, two threaded rods 13, two measuring rods 17 and two connecting plates 16, and a threaded rod 13 and a measuring rod 17 are fixed to each of the two connecting plates 16.

[0039] Specifically, the threaded rod 13 and the measuring rod 17 disposed at the top are fixed by a connecting plate 16, the connecting plate 16 is located outside the connecting column 10, the pushing plate 15 is located inside the connecting column 10, the threaded rod 13 and the measuring rod 17 are connected to the top of the pushing plate 15 after passing through the threaded hole and the sliding groove provided on the connecting column 10 in sequence. The measuring rod 17 and the threaded rod 13 disposed at the bottom are fixed by a connecting plate 16, the connecting plate 16 is located outside the connecting column 10, the pushing plate 15 is located inside the connecting column 10, the measuring rod 17 and the threaded rod 13 are connected to the bottom of the pushing plate 15 after passing through the sliding groove and the threaded hole provided on the connecting column 10 in sequence. More specifically, the threaded hole corresponding to the threaded rod 13 and the sliding groove corresponding to the measuring rod 17 can be provided above and below the pushing plate 15. Two fastening nuts 14 are also provided on the threaded rod 13, wherein one fastening nut 14 is used to fasten with the connecting column 10, and the other fastening nut 14 is used to fasten with the pushing plate 15. Under the measuring action of the measuring rod 17, the pushing plate 15 is pushed by the threaded rod 13 to move to the periphery of the induction coil 5 and fit with the periphery of the induction coil 5, and then the nut 14 is threadedly rotated to fix the position of the threaded rod 13, so that the center position of the induction coil 5 is focused with the center of the atomizing spray disc 22 and the metal bar, so as to ensure that the three-turn induction coil 5 is in a parallel state with each other, avoid the problem of magnetic induction intensity deviation caused by the change of the diameter of the induction coil 5 during transportation, thereby improving the stability of smelting and avoiding the deviation of the metal bar.

[0040] According to an embodiment of the present invention, according to the attached Figure 6As shown, the isolation assembly includes a high temperature resistant ceramic spacer 18, one end of which is placed between the turn spacings of two adjacent turns of the induction coil 5, and the other end passes through the second square hole and the first square hole in sequence and is clamped to the outside of the connecting column 10 through the positioning plate 21. A clamping ring 20 is provided on the high temperature resistant ceramic spacer 18, and correspondingly, a clamping groove is provided on the inner wall of the positioning plate 21. When the clamping ring 20 is clamped in the clamping groove, the high temperature resistant ceramic spacer 18 is fixed to the outside of the connecting column 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 are respectively in contact with the lower surface and the upper surface of the two adjacent turns of the induction coil 5. When fixing the high temperature resistant ceramic spacer 18, it is necessary to move the high temperature resistant ceramic spacer 18 to a suitable position along the vertical direction, and then clamp the positioning plate 21 to the outer surface of the clamping ring 20, and fix the position of the high temperature resistant ceramic spacer 18 in combination with the limiting plate 19, so as to support the turn spacing of the mutually parallel induction coils 5, and at the same time effectively ensure the structural stability of the induction coil 5, and avoid sparking or breakdown problems of the induction coil 5.

[0041] Specifically, since there are two turn intervals between the three-turn induction coil 5 , each connecting column 10 corresponds to two groups of isolation components.

[0042] According to an embodiment of the present invention, Figure 7 As shown, a mounting groove is provided on the inner bottom wall of the induction heating chamber 1, and an atomizing spray disc 22 located at the lower end of the induction heating chamber 1 is fixedly connected through the mounting groove. An air dividing ring 23 is fixedly installed on the upper surface of the atomizing spray disc 22, and the upper end of the air dividing ring 23 is fixedly connected to the lower end of the fixed component. The atomizing spray disc 22 can atomize the molten droplets into fine molten droplets through the nozzle, which is convenient for improving the heat exchange efficiency. The air dividing ring 23 evenly distributes the gas to the inside of the heating chamber, making the gas flow in the heating chamber more uniform. An atomizing chamber 24 is fixedly connected to the lower surface of the induction heating chamber 1, and a connecting pipe 25 is fixedly connected to the lower surface of the atomizing chamber 24. The solution is atomized into fine particles by high-pressure gas injection inside the atomizing chamber 24, and then enters the separator 26 through the connecting pipe 25. One end of the connecting pipe 25 is fixedly connected to a separator 26, and the lower surface of the separator 26 is fixedly connected to a powder collecting bin 27. The atomized solution forms a centrifugal force through the rotating airflow in the separator 26, so that the solid particles settle to the outer wall under the combined action of gravity and centrifugal force and enter the powder collecting bin 27, thereby realizing the separation of solid and gas.

[0043] The working principle of the heating device of the present invention is as follows: first, the melting assembly is installed in the induction heating chamber 1, at which time, the induction coil 5 and the center of the high thermal conductivity ceramic tube 7 are focused, the second fixed disk 11 is placed on the upper surface of the gas dividing ring 23, and then the lower part of the outer surface of the high thermal conductivity ceramic tube 7 passes through the middle part of the second fixed disk 11. The top end of the connecting column 10 is passed through the first circular through hole, and then the lower end thereof is passed through the second circular through hole on the second fixed disk 11, and fixed using the fixing nut 12. Next, under the measuring action of the measuring rod 17, the pushing plate 15 is pushed by the threaded rod 13 to move to the periphery of the induction coil 5 and fit with the periphery of the induction coil 5, and then the nut 14 is threadedly rotated to fix the position of the threaded rod 13, so that the center position of the induction coil 5 is focused with the center of the atomizing spray disc 22 and the metal rod. At the same time, the high-temperature resistant ceramic spacer 18 is moved up and down inside the square hole to a suitable position, and then the positioning plate 21 is clamped to the outer surface of the clamping ring 20, and the position of the high-temperature resistant ceramic spacer 18 is fixed in combination with the limit plate 19, thereby supporting the turn spacing of the induction coils 5 that are parallel to each other. Next, the connecting block 4 is connected to the external block 2 through the copper bolt 3. The external block 2 is connected to the water supply system and the power supply device, so that the middle part of the block is supercooled and the induction coil 5 is powered. The induction coil 5 generates a magnetic field. When the metal bar enters the feed port and reaches the high thermal conductivity ceramic cylinder 7 and approaches the induction coil 5, due to the existence of the magnetic field, eddy currents are generated inside the metal bar, thereby increasing the temperature of the metal bar and melting the metal bar. 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 is formed by the rotating airflow, so that the solid particles settle to the outer wall under the combined action of gravity and centrifugal force, and enter the powder collection bin 27, thereby realizing the separation of solid and gas.
