[0004] The stirring and melting device provided by the present application includes a smelting furnace, a container, a stirring device and a first lifting structure, wherein the smelting furnace has a accommodating cavity, the container is arranged in the accommodating cavity, and the container is used to accommodate the material; the stirring device includes at least one mechanical stirring structure and at least one ultrasonic oscillation structure, at least one mechanical stirring structure includes a stirring component, the stirring component is used to extend into the container to stir the material in the container; at least one ultrasonic oscillation structure includes a vibration component, at least one ultrasonic oscillation structure is connected to the power output end of the first lifting structure so that the vibration component can enter and exit the container; when the vibration component is located in the container, the vibration component can oscillate and disperse the material in the container. When the stirring and melting device provided by the present solution is used for smelting the material, it can stir the melt in the container through at least one mechanical stirring structure, and can also oscillate the melt through at least one ultrasonic oscillation structure, so that the particulate matter (for example, ultrafine particles) can be more evenly distributed in the melt and the problem of agglomeration of mixed particles in the high-temperature melt can be improved. In addition, the vibration component of the ultrasonic oscillation structure is not conducive to being in a high-temperature environment for a long time, otherwise it is easy to crack or break. In the stirring and melting device provided by the present application, the vibration component of the ultrasonic oscillation structure can be moved in and out of the container under the action of the first lifting structure. In other words, according to actual conditions, the stirring component of the mechanical stirring structure can be caused to stir in the container at a certain stage, and the vibration component of the ultrasonic oscillation structure can be caused to leave the container under the action of the first lifting structure. This can reduce the time the vibration component is exposed to high temperature, which helps to prevent the vibration component from being damaged by high temperature. On the other hand, the stirring and melting device provided by the present application integrates melting, mechanical stirring, and ultrasonic dispersion, which can not only reduce material turnover and improve melting efficiency, but also save costs and reduce space.
[0005] In a possible embodiment, the ultrasonic oscillation structure includes an ultrasonic transducer, and the vibration assembly includes an ultrasonic horn and a transmitter. One end of the ultrasonic horn is connected to the ultrasonic transducer, and the other end of the ultrasonic horn is connected to the transmitter to generate stronger ultrasonic energy and more effectively oscillate the melt, thereby enabling the particles to be more evenly dispersed.
[0006] In one possible embodiment, the melting points of both the vibration assembly and the stirring assembly are higher than the melting temperature of the stirring and melting device. This can extend the service life of the vibration assembly in each ultrasonic oscillation structure and the stirring assembly in each mechanical stirring structure, reduce the failure rate and maintenance rate of the stirring and melting device, and thereby improve the operating efficiency of the stirring and melting device. Exemplarily, the material of the vibration assembly and the stirring assembly can include at least one of a ceramic composite material and tungsten.
[0007] In one possible embodiment, the stirring and melting device further includes a second lifting structure, with the container disposed at a power output end of the second lifting structure; the first lifting structure is configured to drive the vibration assembly to extend into the container or extend out of the container; and / or the second lifting structure is configured to drive the container to extend into the container or extend out of the container. The stirring and melting device provided herein can move the vibration assembly in and out of the container using at least one of the first and second lifting structures, as needed, thereby enabling the stirring and melting device to be adapted for a variety of applications and having a wider range of applicability.
[0008] Furthermore, in one possible embodiment, at least one mechanical stirring structure is provided at the power output end of the first lifting structure; the first lifting structure is used to drive the stirring assembly to move so that the stirring assembly extends into the container or extends out of the container. In this solution, the stirring assembly of each mechanical stirring structure can also enter and exit the container, which can reduce the time the stirring assembly is in a high-temperature environment and help prevent the stirring assembly from being damaged by high temperatures. Exemplarily, each mechanical stirring structure and each ultrasonic oscillation structure is sealed to the smelting furnace by a vacuum bellows.
[0009] In a possible embodiment, the stirring and melting device includes a heating unit, which is arranged in the accommodating cavity.

The container is arranged at the power output end of the second lifting structure through the support seat to facilitate the arrangement of the container at the power output end of the second lifting structure.
[0011] In a possible embodiment, the stirring and melting device includes a cooling unit, which is located in the accommodating cavity and is used to cool the container so as to solidify the melt in the container more quickly and reduce the possibility of stratification of the mixed particles and the melt.
[0012] Furthermore, the cooling unit has a cooling chamber that is spaced apart from the heating chamber. The second lifting structure is used to actuate the container, moving it into or out of the cooling chamber. In this solution, the spacing between the heating unit and the cooling unit prevents residual heat from the heating unit from affecting the cooling effect of the cooling unit.

DETAILED DESCRIPTION
[0020] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings.

Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.
[0023] Figure 1 This is a schematic diagram of the structure of a stirring and melting device provided in this application. Figure 1 As shown, the present application provides a stirring and melting device comprising a smelting furnace 1, a container 2, a stirring device 3 and a first lifting structure 4, wherein the smelting furnace 1 has a accommodating chamber A, the container 2 is used to accommodate materials, and the container 2 is arranged in the accommodating chamber A. Exemplarily, the container 2 can be a crucible. The stirring device 3 includes at least one mechanical stirring structure 31 and at least one ultrasonic oscillation structure 32, that is, the stirring device 3 includes one or more mechanical stirring structures 31, and at the same time, the stirring device 3 also includes one or more ultrasonic oscillation structures 32. In a specific implementation, as Figure 1 As shown, the stirring device 3 includes a mechanical stirring structure 31 and two ultrasonic oscillation structures 32. Next, the stirring and melting device will be described. Each mechanical stirring structure 31 includes a stirring component 310, and each stirring component 310 is used to extend into the container 2 to stir the melt in the container 2. Each ultrasonic oscillation structure 32 includes a vibration component 320, and each ultrasonic oscillation structure 32 is connected to the power output end of the first lifting structure 4 (such as Figure 1As shown), the vibration components 320 of each ultrasonic oscillation structure 32 can enter and exit the container 2. It is not difficult to understand that when the vibration component 320 of the ultrasonic oscillation structure 32 is located in the container 2, the vibration component 320 can oscillate and disperse the melt in the container 2. When the stirring and melting device provided by this solution is used for smelting materials, it can stir the melt in the container 2 through at least one mechanical stirring structure 31, and can also oscillate the melt through at least one ultrasonic oscillation structure 32, so that the particulate matter (for example: ultrafine particles) can be more evenly distributed in the melt and the problem of agglomeration of mixed particles in the high-temperature melt can be improved. In addition, the vibration component 320 of the ultrasonic oscillation structure 32 is not conducive to being in a high-temperature environment for a long time, otherwise it is prone to cracking or breaking. In the stirring and melting device provided herein, the vibration assembly 320 of the ultrasonic oscillation structure 32 can be moved in and out of the container 2 under the action of the first lifting structure 4. In other words, depending on actual conditions, the stirring assembly 310 of the mechanical stirring structure 31 can be caused to stir within the container 2 at certain stages, while the vibration assembly 320 of the ultrasonic oscillation structure 32 can be caused to leave the container 2 under the action of the first lifting structure 4. This reduces the time that the vibration assembly 320 is exposed to high temperatures, helping to prevent damage to the vibration assembly 320. Furthermore, the stirring and melting device provided herein integrates smelting, mechanical stirring, and ultrasonic dispersion, which not only reduces material turnover and improves smelting efficiency, but also saves costs and reduces floor space.
[0024] Next, we will combine Figure 1 The ultrasonic oscillation structure 32 is described in detail. Figure 1 As shown, the ultrasonic oscillation structure 32 includes an ultrasonic transducer 321, and the vibration component 320 of the ultrasonic oscillation structure 32 includes an ultrasonic horn 322 and a transmitter 323. One end of the ultrasonic horn 322 is connected to the ultrasonic transducer 321, and the other end of the ultrasonic horn 322 is connected to the transmitter 323. The ultrasonic horn 322 amplifies the mechanical high-frequency vibration of the ultrasonic transducer 321 and transmits it to the transmitter 323, so that the transmitter 323 forms stronger ultrasonic energy and oscillates the melt more effectively, so that the particles can be dispersed more evenly.
[0025] Next, other possible embodiments of the stirring and melting device provided by the present application are described. Specifically, in some embodiments, the melting point of the vibration component 320 of each ultrasonic oscillation structure 32 and the melting point of the stirring component 310 of each mechanical stirring structure 31 are higher than the melting temperature of the stirring and melting device, thereby increasing the service life of the vibration component 320 in each ultrasonic oscillation structure 32 and the stirring component 310 in each mechanical stirring structure 31, reducing the failure rate and maintenance rate of the stirring and melting device, and thus improving the working efficiency of the stirring and melting device. Exemplarily, the material of the vibration component 320 in the ultrasonic oscillation structure 32 and the stirring component 310 in the mechanical stirring structure 31 include at least one of a ceramic composite material and tungsten. That is, the material of the vibration component 320 may include a ceramic composite material or tungsten, and the material of the vibration component 320 may also include both a ceramic composite material and tungsten. Similarly, the material of the stirring component 310 may include a ceramic composite material or tungsten, and the material of the stirring component 310 may also include both a ceramic composite material and tungsten. Furthermore, when the materials of the vibration component 320 in the ultrasonic oscillation structure 32 and the stirring component 310 in the mechanical stirring structure 31 are selected from ceramic composite materials, the materials of both can be selected from special ceramic composite materials. Special ceramic composite materials do not intermesh with high-temperature molten liquids and can meet the requirements of high-temperature operation of 100,000 times or more at a high temperature of 1700°C, which is more conducive to extending the service life of the vibration component 320 in the ultrasonic oscillation structure 32 and the stirring component 310 in the mechanical stirring structure 31. It should be understood that the vibration component 320 and the stirring component 310 are not limited to the above materials and may also include other materials, and this is not an exhaustive list.
[0026] Figure 3 This is a schematic diagram of the structure of another stirring and melting device provided in this application. Figure 3As shown, in a specific implementation, the stirring and melting device may further include a second lifting structure 5, with the container 2 disposed at the power output end of the second lifting structure 5, meaning that the container 2 can be raised and lowered under the action of the second lifting structure 5. It should be understood that the power output end of the first lifting structure 4, i.e., the portion of the first lifting structure 4 that can be raised and lowered, is used to connect to one end of the object being acted upon. Similarly, the power output end of the second lifting structure 5, i.e., the portion of the second lifting structure 5 that can be raised and lowered, is used to connect to one end of the object being acted upon. For example, in the case where the first lifting structure 4 includes a first motor and a first screw structure, and the second lifting structure 5 includes a second motor and a second screw structure, specifically, the first motor drives the screw in the first screw structure to rotate, thereby causing the screw nut in the first screw structure to rise and fall linearly along the screw in the first screw structure. In this embodiment, the screw nut in the first screw structure is the power output end of the first lifting structure 4. In a specific implementation, the first motor may be located above the smelting furnace and a certain distance from the top of the smelting furnace, with the first screw structure located on the side of the first motor facing the smelting furnace. The second motor drives the screw in the second screw structure to rotate, causing the screw nut in the second screw structure to rise and fall linearly along the screw. In this solution, the screw nut in the second screw structure serves as the power output of the second lifting structure 5. In a specific implementation, the second motor can be located within the smelting furnace's accommodating chamber, at the bottom of the accommodating chamber. The second screw structure is located on the side of the second motor facing the container. Of course, the above solution is merely an example; the first lifting structure 4 and the second lifting structure 5 may also have other configurations, and this list is not exhaustive.
[0027] There are many ways to implement the vibration assembly 320 in and out of the container. In one specific implementation, the first lifting structure 4 is used to drive the vibration assembly 320 to move so that the vibration assembly 320 extends into the container 2 or extends out of the container 2. In other words, the vibration assembly 320 can be moved in and out of the container 2 only by the first lifting structure 4 acting on the vibration assembly 320. In another specific implementation, Figure 2As shown, the second lifting structure 5 is used to drive the container 2 to move so that the vibration component 320 extends into the container 2 or extends from the container 2. That is, the vibration component 320 can be moved in and out of the container 2 only by the second lifting structure 5 acting on the container 2. In another specific implementation, the first lifting structure 4 is used to drive the vibration component 320 to move so that the vibration component 320 extends into the container 2 or extends from the container 2, and the second lifting structure 5 is used to drive the container 2 to move so that the vibration component 320 extends into the container 2 or extends from the container 2. That is, the vibration component 320 is moved in and out of the container 2 by the first lifting structure 4 acting on the vibration component 320 and by the second lifting structure 5 acting on the container 2. The stirring and melting device provided in the present application can move the vibration component 320 in and out of the container 2 by at least one of the first lifting structure 4 and the second lifting structure 5 according to actual needs, so that the stirring and melting device can be applied to different application scenarios and has a wider range of applications.
[0028] The following describes a specific implementation of the stirring and melting device, taking as an example a case where the first lifting structure 4 is used to drive the vibration assembly 320 to move so that the vibration assembly 320 extends into the container 2 or extends from the container 2, and the second lifting structure 5 is used to drive the container 2 to move so that the vibration assembly 320 extends into the container 2 or extends from the container 2. For example, the power output end of the first lifting structure 4 has a first position and a second position, and the second position is closer to the bottom of the smelting furnace 1 than the first position; the power output end of the second lifting structure 5 has a third position and a fourth position, and the fourth position is closer to the bottom of the smelting furnace 1 than the third position; Figure 3 As shown, when the power output end of the first lifting structure 4 is located at the first position, the vibration components 320 of the ultrasonic vibration structures 32 are all located on the side of the container 2 away from the bottom of the smelting furnace 1. Figure 4 As shown, when the power output end of the first lifting structure 4 is located at the second position and the power output end of the second lifting structure 5 is located at the third position, the vibration component 320 of each ultrasonic oscillation structure 32 is located in the container 2, thereby being able to oscillate the melt in the container 2 to make the dispersion of the particles more uniform.
[0029] Please continue to refer to Figure 4 In a specific implementation, the second lifting structure 5 may include a support seat 51, which is arranged at the power output end of the second lifting structure 5. The container 2 is arranged at the power output end of the second lifting structure 5 through the support seat 51, so as to facilitate the arrangement of the container 2 at the power output end of the second lifting structure 5.
[0030] For further information, please refer to Figure 4In some embodiments, each of the mechanical stirring structures 31 is also provided at the power output end of the first lifting structure 4. The first lifting structure 4 is used to drive the stirring assembly 310 to move so that the stirring assembly 310 extends into the container 2 or extends out of the container 2. Specifically, when the first lifting structure 4 is used to drive the vibration assembly 320 to move so that the vibration assembly 320 extends into the container 2 or extends out of the container 2, the stirring assembly 310 and the vibration assembly 320 can be synchronously moved in and out of the container 2 under the action of the first lifting structure 4. When the second lifting structure 5 is used to drive the container 2 to move so that the vibration assembly 320 extends into the container 2 or extends out of the container 2, the first lifting structure 4 acts on the stirring assembly 310 and the second lifting structure 5 acts on the container 2, thereby enabling the stirring assembly 310 to move in and out of the container 2. The first lifting structure 4 is used to drive the vibration component 320 to move so that the vibration component 320 extends into the container 2 or extends from the container 2, and the second lifting structure 5 is used to drive the container 2 to move so that the vibration component 320 extends into the container 2 or extends from the container 2. The first lifting structure 4 acts on the stirring component 310, and the second lifting structure 5 acts on the container 2, thereby realizing the stirring component 310 entering and exiting the container 2.
[0031] The following describes an example of a case where the first lifting structure 4 is used to drive the vibration assembly 320 so that the vibration assembly 320 extends into the container 2 or the vibration assembly 310 extends from the container 2, and the second lifting structure 5 is used to drive the container 2 so that the vibration assembly 320 extends into the container 2 or the vibration assembly 320 extends from the container 2. The specific method of moving the stirring assembly 310 into and out of the container 2 is described below. When the power output end of the first lifting structure 4 is in the first position, the stirring assemblies 310 of each of the mechanical stirring structures 31 are located on the side of the container 2 that is away from the bottom of the smelting furnace 1. When the power output end of the first lifting structure 4 is in the second position and the power output end of the second lifting structure 5 is in the third position, the stirring assemblies 310 of each of the mechanical stirring structures 31 are located in the container 2. It is understood that when the stirring assembly 310 is located in the container 2, it can stir the melt in the container 2. In this solution, the stirring assembly 310 of each mechanical stirring structure 31 can also enter and exit the container 2, which can reduce the time that the stirring assembly 310 is exposed to a high temperature environment and help prevent the stirring assembly 310 from being damaged by high temperatures. For example, each mechanical stirring structure 31 and each ultrasonic oscillation structure 32 are sealed to the smelting furnace 1 via a vacuum bellows.
[0032] Of course, in other implementations, the stirring and melting device may also include a third lifting structure, wherein the power output end of the third lifting structure has a fifth position and a sixth position, wherein the sixth position is closer to the bottom of the smelting furnace 1 than the fifth position. The above-mentioned mechanical stirring structures 31 are arranged at the power output end of the third lifting structure. Taking the case where the first lifting structure 4 is used to drive the vibration assembly 320 to move so that the vibration assembly 320 extends into the container 2 or extends out of the container 2, and the second lifting structure 5 is used to drive the container 2 to move so that the vibration assembly 320 extends into the container 2 or extends out of the container 2 as an example, when the power output end of the third lifting structure is in the fifth position, the stirring assembly 310 of each of the above-mentioned mechanical stirring structures 31 is located on the side of the container 2 away from the bottom of the smelting furnace 1; when the power output end of the third lifting structure is in the sixth position and the power output end of the second lifting structure 5 is in the third position, the stirring assembly 310 of each of the above-mentioned mechanical stirring structures 31 is located in the container 2.
[0033] Please continue to refer to Figure 4 When the above-mentioned mechanical stirring structure 31 is specifically set up, in one possible implementation method, the mechanical stirring structure 31 includes a driving motor 330, and the stirring assembly 310 includes a stirring rod 311 and a stirring head 312, one end of the stirring rod 311 is connected to the output shaft of the driving motor 330, and the other end of the stirring rod 311 is connected to the stirring head 312.
[0034] Please continue to refer to Figure 4 In a specific embodiment, the stirring and melting device includes a heating unit 6, which is disposed in the accommodating chamber A and is used to heat the container 2. Specifically, the heating unit 6 has a heating chamber, and the second lifting structure 5 is used to drive the container 2 to move so that the container 2 moves into the heating chamber or moves outside the heating chamber. Still taking the case where the first lifting structure 4 is used to drive the vibration component 320 to move so that the vibration component 320 extends into the container 2 or extends from the container 2, and the second lifting structure 5 is used to drive the container 2 to move so that the vibration component 320 extends into the container 2 or extends from the container 2 as an example, in a specific implementation, when the power output end of the second lifting structure 5 is in the third position, the container 2 is located in the heating chamber so that the material in the container 2 can be heated and melted into a molten liquid; when the power output end of the second lifting structure 5 is in the fourth position, the container 2 is located outside the heating chamber. Specifically, the heating method of the heating unit 6 includes but is not limited to resistance heating or induction heating.
[0035] Figure 5 This is a schematic diagram of the structure of another stirring and melting device provided in this application. Figure 5As shown, the stirring and melting device includes a cooling unit 7, which is located in the accommodating chamber A and is used to cool the container 2 so as to make the melt in the container 2 solidify more quickly and reduce the possibility of stratification of the mixed particles and the melt.
[0036] When the cooling unit 7 is specifically set, in a specific embodiment, the cooling unit 7 has a cooling cavity, which is spaced apart from the heating cavity; the second lifting structure 5 is used to drive the container to move so that the container moves into the cooling cavity or moves to the outside of the cooling cavity. For example, the cooling unit 7 is located on the side of the heating unit 6 facing the bottom of the smelting furnace 1, and when the power output end of the second lifting structure 5 is in the fourth position, the cooling unit 7 can cool the container 2. In this solution, the heating unit 6 and the cooling unit 7 are arranged along the lifting direction of the power output end of the second lifting structure 5, which can avoid the influence of the residual heat of the heating unit 6 on the cooling effect of the cooling unit 7. Of course, in other implementations, the stirring and melting device can also be provided without the cooling unit 7, and the container 2 and the high-temperature melt therein are cooled along with the furnace.
[0037] In a specific embodiment, the stirring and melting device further includes a first temperature detection assembly 100 and a second temperature detection assembly 200. The first temperature detection assembly 100 is fixed to the power output end of the first lifting structure 4. When the power output end of the first lifting structure 4 is in the first position, the first temperature detection assembly 100 is located on the side of the container 2 facing away from the bottom of the smelting furnace 1. When the power output end of the first lifting structure 4 is in the second position and the power output end of the second lifting structure 5 is in the third position, the first temperature detection assembly 100 extends into the container 2 and is immersed in the melt to detect the temperature of the melt in the container 2. The second temperature detection assembly 200 is fixed to the support base 51 and is used to detect the temperature of the bottom of the container 2. The dual detection of the first temperature detection assembly 100 and the second temperature detection assembly 200 can make the temperature detection of the stirring and melting device more accurate, which is conducive to more precise temperature control of the stirring and melting device. Exemplarily, both the first temperature detection assembly 100 and the second temperature detection assembly 200 can include thermocouples.
[0038] It is easy to understand that the stirring and melting device includes a feeding component 9, which is located at the top of the stirring and melting device and is used to add corresponding materials into the container 2. Exemplarily, the feeding component 9 can be a feeding funnel.
[0039] Please continue to refer to Figure 5 In some embodiments, the stirring and melting device further includes a gas protection unit 8, which includes a gas storage tank 81 and a vacuum pump 82. The gas storage tank 81 and the vacuum pump 82 are both connected to the smelting furnace 1, wherein the vacuum pump 82 is used to evacuate the containing chamber A, and the gas storage tank 81 is used to fill the containing chamber A with inert gas.
[0040] Furthermore, in some embodiments, the smelting furnace 1 is further connected to an exhaust valve 83 , and the exhaust valve 83 is used to discharge the inert gas in the containing chamber of the smelting furnace 1 .
[0041] The following is an example of the working process of a stirring and melting device provided by the present application. Specifically, the working process of a stirring and melting device provided by the present application is as follows:
[0042] Step 1: The power output end of the second lifting assembly is in the fourth position, and the crucible containing the material is manually placed on the support base 51, and then the furnace door of the smelting furnace 1 is closed;
[0043] Step 2: Start the vacuum pump 82 to evacuate the accommodating chamber A of the smelting furnace 1, and then introduce an inert protective gas into the accommodating chamber A of the smelting furnace 1;
[0044] Step 3: The power output end of the second lifting assembly is raised to the third position, the heating unit 6 is started, and after the material is melted (for example, heated to about 1400° C. to 1600° C.), the mixed powder in the sealed feeding funnel is poured into the crucible;
[0045] Step 4: Start the first lifting structure 4, so that the power output end of the first lifting structure 4 moves to the second position, the stirring component 310 of the mechanical stirring structure 31, the vibration component 320 of the ultrasonic vibration structure 32, and the first temperature detection component 100 extend into the high-temperature melt in the crucible to operate;
[0046] Step 5: After repeated stirring and ultrasonic vibration for a period of time, when the melt is evenly mixed, the temperature is reduced to about 1200℃ and kept warm when the melt is semi-solid;
[0047] Step 6: The power output end of the first lifting structure 4 moves to the first position, and the power output end of the second lifting assembly moves to the fourth position, and the melt in the crucible cools with the furnace until the billet is cooled and formed;
[0048] Step 7: After the furnace has cooled down, close the gas protection unit 8, open the exhaust valve 83 to exhaust the inert protective gas, and then take out the crucible.
