Description

Technical Field

[0001] This application relates to the field of centrifugal preparation of metal powder manufacturing, and in particular to an atomizer inverted device and a centrifugal atomization equipment. Background Technology

[0002] Centrifugal atomization is a method for preparing metal powders, and the atomizer plays a crucial role in the process. Traditional atomizer installation methods typically require placing the atomizer inside the atomization chamber. If the atomizer or atomization head needs to be replaced, workers need to open the manhole to enter the atomization chamber. This not only makes atomizer replacement and maintenance difficult but also increases the risk of workers entering a confined space.

[0003] For example, Chinese patent CN 107127350 A discloses a metal centrifugal atomizing powder-making device. The device has a metal melting smelting auger at the center of the top of the atomizing tank, a gas delivery pipe at the lower end of its side wall for supplying driving gas to the gas-driven rotating shaft, and a powder outlet pipe at the bottom. The gas delivery pipe is connected to a high-pressure gas source. The rotating disk is located directly below the metal melting auger and is connected to the top of the gas-driven rotating shaft, which drives it to rotate at high speed. When replacing the rotating disk and the gas-driven rotating shaft of this centrifugal atomizing device, it is necessary to open the manhole and enter the atomizing tank. If the inert gas in the atomizing tank is not completely removed, workers entering may be at risk of suffocation. After the replacement, inert gas must be reintroduced for ventilation. The operation process is complicated and takes a long time, causing the equipment to be unable to operate normally for a long time.

[0004] To address these issues, this application proposes an inverted atomizer device and a centrifugal atomization apparatus. Utility Model Content

The atomizer inversion device can realize the direct replacement of atomizer and atomizing head from the outside of the atomization chamber, thereby avoiding workers from entering the atomization chamber and reducing the risk of working in a confined space. At the same time, the design of the atomizer inversion device greatly shortens the time for replacing atomizer and atomizing head, effectively improving production efficiency and optimizing the production process.

[0006] According to one aspect of the present invention, an atomizer inverted hanging device is provided, comprising: a sleeve, wherein a support plate is provided inside the sleeve, and an atomizer is invertedly placed inside the sleeve via the support plate, with the atomizing head of the atomizer extending downwards outside the sleeve; a liquid guide tube, the liquid guide tube being fixed to the sleeve, one end of the liquid guide tube forming an inlet and the other end forming an outlet extending toward the atomizing head; and a connecting structure, the connecting structure being disposed outside the sleeve, the connecting structure being used to detachably connect the sleeve to the atomizing chamber.

[0007] In some embodiments of this utility model, the support plate is an annular plate, the atomizer is supported above the annular plate, and the atomizing head passes through the middle of the annular plate from top to bottom.

[0015] According to another aspect of the present invention, a centrifugal atomizing device is provided, including the above-described atomizer inverting device.

[0016] Compared with the prior art, the present invention achieves the following technical effects: This application provides an atomizer inversion device.

The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0022] This application discloses an inverted atomizer device. For example... Figures 1-3As shown, the atomizer inverted device includes a sleeve 2, a liquid guide tube 5, and a connecting structure. The sleeve 2 has a support plate 8 inside, and the atomizer 1 is placed upside down inside the sleeve 2 through the support plate 8, with the atomizing head 6 of the atomizer 1 extending downwards outside the sleeve 2. The liquid guide tube 5 is fixed to the sleeve 2, with one end forming an inlet and the other end forming an outlet extending towards the atomizing head 6. The connecting structure is located outside the sleeve 2 and is used to detachably connect the sleeve 2 to the atomizing chamber 7.

[0023] By using the atomizer inverted device in this technical solution, the atomizer 1 can be installed upside down on the top of the atomization chamber 7, so that the atomizing head 6 is located inside the atomization chamber 7. The molten metal enters from the inlet of the liquid guide pipe 5 and drips to the atomizing head 6 through the outlet of the liquid guide pipe 5. The atomizing head 6 rotates at high speed to throw the molten metal out for centrifugal atomization. When maintenance of the atomizer 1 is required, such as replacing the atomizing head 6, the operator can remove the sleeve 2 from the atomization chamber 7, and then replace the atomizer 1 and the atomizing head 6 from outside the atomization chamber 7, avoiding the need for workers to enter the atomization chamber. Operating inside chamber 7 effectively solves the problem of suffocation caused by limited space, ensuring worker safety. Furthermore, the inverted device has a simple structure and is easy to disassemble, optimizing the process of replacing atomizer 1 and atomizing head 6. The atomizer 1, based on the sleeve 2, is essentially installed openly outside the atomization chamber 7, which facilitates heat dissipation and extends its service life. Simultaneously, workers do not need to enter the atomization chamber 7, reducing the time required for ventilation and thus minimizing equipment downtime, effectively improving production efficiency and optimizing the production process.

[0024] In some embodiments of this utility model, such as Figure 3 As shown, the support plate 8 is an annular plate, the atomizer 1 is supported above the annular plate, and the atomizing head 6 passes through the middle of the annular plate from top to bottom.

[0025] In this embodiment, by providing an annular plate inside the sleeve 2, the atomizer 1 can be supported circumferentially from the bottom edge of the atomizer 1, making the force on the atomizer 1 more uniform and improving the stability of the atomizer 1 installed inside the sleeve 2.

[0026] In some embodiments of this utility model, the annular plate can be disposed near the bottom end of the sleeve 2.

[0027] In some embodiments of this utility model, such as Figure 3 As shown, the atomizer inverted device also includes a sealing ring 4, which is sandwiched between the atomizer 1 and the annular plate.

[0028] It should be understood that the sealing ring 4 is hollowed out around the center of the annular plate and is evenly sandwiched between the atomizer 1 and the annular plate. It mainly plays the role of sealing and buffering, which not only ensures the sealing of the atomization chamber 7, but also improves the anti-vibration effect of the atomizer 1 during operation and enhances the protection of the atomizer 1.

[0029] In some embodiments of this utility model, the sealing ring 4 can be made of polytetrafluoroethylene, silicone, graphite, etc.

[0030] In some embodiments of this utility model, such as Figure 3 As shown, the atomizer inverted device also includes a pressure cylinder 3, which is inserted into the sleeve 2 from top to bottom and presses against the upper end of the atomizer 1. The pressure cylinder 3 and the sleeve 2 are detachably connected.

[0031] In this embodiment, by applying a certain pressure to the atomizer 1 through the pressure cylinder 3, the atomizer 1 can be stabilized in the space between the pressure cylinder 3 and the support plate 8 inside the sleeve 2. This can avoid the possibility of shaking when the atomizer 1 rotates at high speed, and improve the stability of the atomizer 1 operation. When the atomizer 1 needs to be maintained, the pressure cylinder 3 can be removed from the sleeve 2, and the atomizer 1 can be taken out from the sleeve 2. It has the advantages of convenient disassembly and maintenance.

[0032] Furthermore, such as Figure 3 As shown, the atomizer 1 fits tightly against the inner wall of the sleeve 2, which prevents the atomizer 1 from radially shifting within the sleeve 2 during operation, thereby further improving the stability of the atomizer 1's operation.

[0033] In some embodiments of this utility model, such as Figure 3 As shown, a first flange 9 is fixed to the top of the pressure cylinder 3, and the first flange 9 is connected to the top surface of the sleeve 2 by bolts.

[0034] In this embodiment, the outer diameter of the first flange 9 is larger than the inner diameter of the sleeve 2. The first flange 9 can be placed on the top of the sleeve 2, and the bottom of the pressure cylinder 3 is in contact with the atomizer 1. Multiple threaded holes are opened on the top surface of the sleeve 2 in the circumferential direction, so that the first flange 9 is fixed to the top of the sleeve 2 by bolts, while the pressure cylinder 3 presses the atomizer 1 with a certain force.

[0035] In other embodiments of this utility model, the pressure cylinder 3 can also be detachably connected to the sleeve 2 in other ways, such as by a lock, pin, or other structure. Those skilled in the art can make reasonable settings as needed, and no limitation is made here.

[0036] In some embodiments of this utility model, such as Figure 3 As shown, the connection structure includes a second flange 10 fixed to the outer wall of the sleeve 2, and the second flange 10 is connected to the atomizing chamber 7 by bolts.

[0037] In this embodiment, it should be understood that the top of the atomizing chamber 7 is provided with an installation port 11 that connects the inside and outside. The outer diameter of the second flange 10 is larger than the installation port 11. After the sleeve 2 is inserted into the installation port 11, the atomizing head 6 of the atomizer 1 extends into the atomizing chamber 7. At the same time, the second flange 10 is supported on the top surface of the atomizing chamber 7. Multiple threaded holes are opened on the top surface of the atomizing chamber 7 in the circumferential direction, so that the second flange 10 is fixed to the top of the atomizing chamber 7 by bolts.

[0038] Furthermore, a sealing ring can be installed between the second flange 10 and the top surface of the atomizing chamber 7 for sealing.

[0039] In other embodiments of this utility model, the second flange 10 may also be detachably connected to the top of the atomizing chamber 7 in other ways, such as by means of a latch, pin, or other structure. Those skilled in the art can make reasonable settings as needed, and no limitation is made here.

[0040] In some embodiments of this utility model, the second flange 10 may be located near the top of the sleeve 2.

[0041] In some embodiments of this utility model, such as Figure 3 As shown, the liquid guide pipe 5 is fixed on the second flange 10, with the inlet of the liquid guide pipe 5 located above the second flange 10 and the outlet of the liquid guide pipe 5 located below the second flange 10.

[0042] Specifically, in this embodiment, a through hole is provided on the second flange 10 for the liquid guide pipe 5 to pass through. The liquid guide pipe 5 can be fixed at the through hole by welding. After the sleeve 2 is installed on the atomizing chamber 7 through the second flange 10, the top end (inlet) of the liquid guide pipe 5 is located outside the atomizing chamber 7, and the bottom end (outlet) of the liquid guide pipe 5 is located inside the atomizing chamber 7 and can flow the molten metal to the surface of the atomizing head 6 through the small hole at the bottom.

[0043] In some embodiments of this utility model, the sleeve 2, the pressure cylinder 3, the liquid guide tube 5, etc., can be made of stainless steel, aluminum alloy, or other materials.

[0044] This application discloses a centrifugal atomization device. For example... Figure 4 As shown, the centrifugal atomization device includes an atomization chamber 7, an atomizer 1, and the aforementioned atomizer inverting device.

[0045] The atomizing chamber 7 has an installation port 11 at the top for mounting the sleeve 2 and the second flange 10. The main body of the atomizer 1 is a high-speed rotating motor. The main shaft end of the atomizer 1 has an installation hole. The atomizing head 6 is fixed to the installation hole at the main shaft end of the atomizer 1 by a snap-locking method. When the atomizer 1 is installed on the atomizer inverted device, the main body of the atomizer 1 is located inside the sleeve 2, and the atomizing head 6 is located outside the sleeve 2. When the atomizer 1 is working, it rotates at high speed, driving the atomizing head 6 to rotate together. The molten metal flows through the guide pipe to the upper part of the rapidly rotating atomizing head 6. Under the action of centrifugal force, the molten metal is thrown out to form metal powder.

[0046] In some embodiments of this utility model, such as Figure 3 As shown, when the size of the atomizing head 6 is larger than the hollow cutout of the support plate 8, the main body of the atomizer 1 can be installed in the sleeve 2 first, and then the atomizing head 6 can be installed on the main shaft end of the atomizer 1 from the bottom of the sleeve 2 by means of a snap fastener.

[0047] In other embodiments of this utility model, when the size of the atomizing head 6 is smaller than the hollow cutout of the support plate 8, that is, when the atomizing head 6 can directly pass through the support plate 8, it is also possible to first install the atomizing head 6 on the main shaft end of the atomizer 1 by means of a snap fastener, and then install the whole assembly in the sleeve 2.

[0048] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
