Description

Technical Field

[0001] This invention relates to the field of aluminum alloy purification flux technology, and in particular to a corrosion-resistant vacuum reactor device for remelting flux. Background Technology

[0002] Currently, during the smelting of aluminum and aluminum alloys, the molten aluminum and aluminum alloy readily react with moisture in the air, producing impurities such as hydrogen and oxides. The raw and auxiliary materials added during smelting also introduce harmful elements such as alkali metals into the melt, significantly impacting the quality of aluminum products. Therefore, fluxes with NaCl-MgCl2-KCl as their main components are used for refining during the aluminum and aluminum alloy casting process to remove impurities such as hydrogen, oxides, and alkali metals. However, the flux preparation process may suffer from sealing failures. These failures are difficult to detect during the reaction process. Poor sealing of the vacuum furnace allows outside air to enter, and the magnesium chloride component in the flux easily reacts with water in the air to form crystalline hydrates. During preparation, this generates magnesium oxide and hydrochloric acid corrosive gases. These crystalline hydrates not only significantly affect the effectiveness of the flux used for aluminum and aluminum alloys but also reduce the lifespan of the equipment. Summary of the Invention

[0003] In view of the above problems, the present invention is proposed to provide a corrosion-resistant vacuum reactor device for remelting flux that overcomes or at least partially solves the above problems. It can solve the problem that the sealing failure of the vacuum furnace is not easy to detect during the reaction process, and achieve the effect of detecting the sealing failure of the vacuum furnace, preventing the impact on the quality of flux for aluminum and aluminum alloys and the damage to the vacuum furnace.

[0004] Specifically, the present invention provides a corrosion-resistant vacuum reactor apparatus for remelting flux, comprising: The furnace body has an upward-facing cavity inside; A cover, wherein the cover is disposed at the opening; A sealing ring is disposed between the furnace body and the cover to ensure a sealed connection between the furnace body and the cover; Multiple shape memory alloys are disposed on the outside of the sealing ring so that the shape memory alloys deform when heat leakage occurs due to failure at the corresponding position of the sealing ring. Multiple electronic tags and an electronic tag reader are provided. The electronic tags are disposed on the inside of the shape memory alloy so that the electronic tags are hidden from being read by the electronic tag reader, and the electronic tags are exposed from the inside of the shape memory alloy when the shape memory alloy is deformed, and then read by the electronic tag reader.

[0005] Optionally, the remelting flux corrosion-resistant vacuum reactor device further includes a phase change material, which is disposed between the sealing ring and the shape memory alloy, and the phase change material is thermally connected to the shape memory alloy.

[0006] Optionally, the outer peripheral surface of the sealing ring is provided with a process groove that penetrates the top surface of the sealing ring, the process groove does not penetrate the bottom surface of the sealing ring, and the process groove does not penetrate the inner surface of the sealing ring. The corrosion-resistant vacuum reactor for remelting flux also includes a heat-conducting strip, which is disposed in the process tank and is thermally connected to the phase change material.

[0007] Optionally, the remelting flux corrosion-resistant vacuum reactor device further includes a cooling ring, which is fixed at the furnace body opening. The cooling ring has an annular groove, and the sealing ring closes the upper opening of the annular groove or is inserted into the annular groove. The sealing ring and the bottom surface of the annular groove define an annular cooling cavity. The cooling ring is provided with a water inlet and a water outlet, which communicate with the annular cooling cavity.

[0008] Optionally, the heat-conducting strip is a copper strip or a steel strip.

[0009] Optionally, the width of the process tank is 0.2-0.5 mm.

[0010] Optionally, the sealing ring is a graphite sealing ring, and the phase change material is a solid-solid phase change material.

[0011] Optionally, the remelting flux corrosion-resistant vacuum reactor device further includes a fixing ring, which is disposed on the outer edge of the phase change material to fix the phase change material, and the shape memory alloy is welded to the outside of the fixing ring.

[0012] Optionally, the corrosion-resistant vacuum reactor for remelting flux further includes: A feed pipe is disposed on the cover and communicates with the cavity; A discharge pipe is disposed on the cover and communicates with the cavity; An air extraction pipe is provided on the cover and communicates with the cavity; A vent pipe, one end of which is connected to the furnace body and the other end of which is connected to an argon cylinder; The furnace body has multiple fixing feet, which are located at the bottom of the furnace body.

[0013] Optionally, the corrosion-resistant vacuum reactor for remelting flux is used to prepare fluxes for aluminum and aluminum alloys.

[0014] In the corrosion-resistant vacuum reactor apparatus for remelting flux of the present invention, the presence of a sealing ring prevents the entry of outside air during solvent preparation. Furthermore, the addition of a shape memory alloy outside the sealing ring, with an electronic tag inside the shape memory alloy, ensures that the seal is effective when the seal is intact. When the seal fails, heat in the vacuum furnace diffuses to the outside through the failure point, causing the shape memory alloy to bend and expose the electronic tag inside. The exposed tag is then read by the electronic tag reader. By detecting the vacuum furnace seal failure and its location during the reaction process, timely resealing is performed to prevent impact on the quality of the flux used for aluminum and aluminum alloys and to prevent corrosion of the vacuum furnace.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0021] Figure 1This is a schematic structural diagram of a corrosion-resistant vacuum reactor apparatus for remelting flux according to an embodiment of the present invention, as shown below. Figure 1 As shown, and refer to Figures 2 to 7 This invention provides a corrosion-resistant vacuum reactor for remelting flux, comprising: a furnace body 1, a cover 2, a sealing ring 3, multiple shape memory alloys 5, multiple electronic tags 8, and an electronic tag reader. The furnace body 1 has an upward-facing cavity. The cover 2 is positioned at the opening. The sealing ring 3 is positioned between the furnace body 1 and the cover 2 to ensure a sealed connection. The shape memory alloys 5 are positioned outside the sealing ring 3, allowing them to deform when heat leakage occurs due to the failure of the sealing ring 3. The electronic tags 8 are positioned inside the shape memory alloys 5, concealing them from being read by the electronic tag reader, and allowing them to be exposed from the inside of the shape memory alloys 5 when they deform, thus being read by the electronic tag reader.

[0022] In the corrosion-resistant vacuum reactor apparatus for remelting flux in this embodiment of the invention, a shape memory alloy 5 is placed outside the sealing ring 3, and an electronic tag 8 is attached to the inner side of the shape memory alloy 5 to block the signal transmission of the electronic tag 8 and the electronic tag reader. When the seal fails, the vacuum furnace dissipates heat to the outside through the location of the seal failure. The increased outside temperature causes the shape memory alloy 5 to deform, exposing the electronic tag 8 on the inner side of the shape memory alloy 5. The electronic tag 8 is then read by the electronic tag reader, allowing the vacuum furnace seal failure to be detected during the reaction process. This prevents the quality of the flux used for aluminum and aluminum alloys from being affected and prevents damage to the vacuum furnace.

[0023] In some embodiments of the present invention, multiple shape memory alloys 5 are uniformly arranged around the sealing ring 3, and electronic tags 8 are arranged in a one-to-one correspondence with shape memory alloys 5, so that when the sealing ring 3 fails, the electronic tag reader can read different electronic tags 8 to determine the failure location.

[0024] In some embodiments of the present invention, such as Figures 3 to 5 As shown, the corrosion-resistant vacuum reactor device for remelting flux also includes a phase change material 4, which is disposed between the sealing ring 3 and the shape memory alloy 5, and the phase change material 4 is thermally connected to the shape memory alloy 5.

[0025] When the seal fails and heat leakage occurs, the leaked heat is directly conducted to the shape memory alloy 5, which could burn the electronic tag 8 attached to the shape memory alloy 5. The phase change material 4 does not overheat after storing the leaked heat; that is, the temperature of the phase change material 4 will not become too high. In this embodiment, a phase change material 4 is added to the sealing ring 3 and the shape memory alloy 5. The leaked heat is stored in the phase change material 4, which heats the shape memory alloy 5, causing it to deform, without burning the electronic tag 8, thus protecting the electronic tag 8.

[0026] In some embodiments of the present invention, such as Figure 6 and Figure 7 As shown, the upper end of the shape memory alloy 5 is connected to the upper end of the phase change material 4. When the vacuum furnace is effectively sealed, the electronic tag 8 is located inside the shape memory alloy 5, and the shape memory alloy 5 blocks the electronic tag 8, preventing the electronic tag reader from reading it. When the vacuum furnace seal fails, heat is stored in the phase change material 4, which heats the shape memory alloy 5. The lower end of the shape memory alloy 5 flips outward, exposing the electronic tag 8 inside the shape memory alloy 5, allowing the electronic tag reader to read it.

[0027] In some embodiments of the present invention, such as Figure 3 As shown, the outer circumferential surface of the sealing ring 3 is provided with a process groove that penetrates the top surface of the sealing ring 3, but does not penetrate the bottom surface or the inner surface of the sealing ring 3. The corrosion-resistant vacuum reactor device for remelting flux also includes a heat-conducting strip 9, which is disposed in the process groove and is thermally connected to the phase change material 4. When the seal fails, heat is rapidly transferred to the phase change material 4 via the heat-conducting strip 9, and then the phase change material 4 heats the shape memory alloy 5. The shape memory alloy 5 deforms, and the electronic tag 8 on the inner side of the shape memory alloy is exposed. The electronic tag reader reads the electronic tag 8, thereby detecting the vacuum furnace seal failure and preventing it from affecting the quality of the flux used for aluminum and aluminum alloys.

[0028] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the corrosion-resistant vacuum reactor for remelting flux also includes a cooling ring 6, which is fixed at the opening of the furnace body 1. The cooling ring 6 has an annular groove, and a sealing ring 3 closes the upper opening of the annular groove or is inserted into the annular groove. The sealing ring 3 and the bottom surface of the annular groove define an annular cooling chamber 7. The cooling ring 6 is provided with a water inlet and a water outlet, which are connected to the annular cooling chamber 7. By setting the cooling ring 6, cooling water can be circulated in the annular cooling chamber 7 of the cooling ring 6 to cool the sealing ring 3, thereby improving the service life of the sealing ring 3 and preventing deformation of the sealing ring 3 due to high temperature environment during use, which would affect its sealing effect.

[0029] In some alternative embodiments of the invention, the coolant is cooling oil.

[0030] In some embodiments of the present invention, the heat-conducting strip 9 is a copper strip. Copper has good thermal conductivity and can quickly transfer heat to the shape memory metal. Copper has strong corrosion resistance, which prevents the electronic tag reader from failing to recognize the sealing ring 3 due to corrosion of the heat-conducting strip 9 in the event of leakage of corrosive gas generated after the reaction.

[0031] In some alternative embodiments of the present invention, the heat-conducting strip 9 is a steel strip with high hardness, which can maintain its performance in high temperature and high corrosion environments and prevent the heat-conducting strip 9 from being damaged due to high temperature and high corrosion environments.

[0032] In some embodiments of the present invention, the width of the process groove is 0.2-0.5 mm (e.g., 0.2 mm, 0.3 mm, 0.4 mm, or 0.5 mm), preferably 0.35 mm. When the width of the process groove is 0.35 mm, the thickness of the heat-conducting strip 9 is also 0.35 mm, so that the heat-conducting strip 9 can be embedded in the process groove, preventing gaps between the heat-conducting strip 9 and the sealing ring 3 from affecting heat transfer.

[0033] In some embodiments of the present invention, the sealing ring is a graphite sealing ring 3. The graphite sealing ring 3 can maintain good sealing performance even in high-temperature and corrosive environments, preventing leakage of high-temperature corrosive gases inside the vacuum furnace and thus preventing the sealing ring 3 from failing. The graphite sealing ring 3 has good elasticity. When the fastening between the furnace body 1 and the cover 2 loosens, the graphite will deform to a certain extent, which can effectively prevent media leakage and achieve a sealing effect.

[0034] In some embodiments of the present invention, the phase change material 4 is a solid-solid phase change material. Solid-solid phase change materials do not undergo phase changes during the conversion process, making them easy to fix. Furthermore, solid-solid phase change materials exhibit minimal volume changes, thus avoiding leakage problems.

[0035] In some embodiments of the present invention, such as Figure 4 and Figure 5 As shown, the corrosion-resistant vacuum reactor for remelting flux also includes a fixing ring, which is located on the outer edge of the phase change material 4 to fix the phase change material 4. The shape memory alloy 5 is welded to the outside of the fixing ring. The phase change material 4 will deform when affected by temperature changes or compression. The fixing ring fixes the phase change material 4 to prevent the phase change material 4 from changing position.

[0036] In some embodiments of the present invention, the retaining ring is made of metal, enabling the retaining ring to transfer heat to the shape memory alloy 5.

[0037] In some embodiments of the present invention, such as Figure 1 As shown, the corrosion-resistant vacuum reactor for remelting flux also includes: a feed pipe 21, a discharge pipe 22, a suction pipe 23, a vent pipe 11, and a fixing foot.

[0038] The feed pipe 21 is installed on the cover 2, and the feed pipe 21 is connected to the cavity. The feed pipe 21 is fixedly welded to the center of the cover 2.

[0039] The discharge pipe 22 is installed on the cover 2 and is connected to the cavity. The discharge pipe 22 is fixedly welded to the left and right sides of the inlet pipe 21.

[0040] The exhaust pipe 23 is installed on the cover 2 and is connected to the cavity. The other end of the exhaust pipe 23 is connected to a vacuum pump. After the vacuum furnace is sealed, the switch of the exhaust pipe 23 is turned on to evacuate the cavity and discharge the gas generated in the furnace 1 during the reaction process.

[0041] One end of the vent pipe 11 is connected to the furnace body 1, and the other end of the vent pipe 11 is connected to the argon cylinder, so that when the furnace body 1 is under vacuum, the argon gas in the argon cylinder can be introduced into the vacuum furnace by opening the switch of the vent pipe 11 to perform vacuum grate vacuum treatment.

[0042] Multiple fixing feet are provided, which are located at the bottom of the furnace body 1. The angle between each fixing foot is 120°. The fixing feet contact the ground, so that the furnace body 1 is placed stably and vertically, avoiding damage to the ground due to excessive furnace temperature.

[0043] In some optional embodiments of the present invention, a filter screen is provided at the exhaust pipe 23 to separate the raw material from the gas when the furnace body 1 is evacuated through the exhaust pipe 23, so as to prevent the raw material from being extracted when the gas in the vacuum furnace is extracted.

[0044] In some optional embodiments of the present invention, a first hygrometer is provided on the top of the furnace body 1 and / or the cover 2, and a second hygrometer is provided on the exhaust pipe 23.

[0045] If the working power of the vacuum pump is too high, it will cause the airflow to accumulate in the inlet area of ​​the suction pipe 23. In other words, it will cause the airflow to accumulate in the upper part of the furnace body 1. Since the temperature at the top of the furnace body 1 and the cover 2 is relatively lower than the temperature at the bottom of the furnace body 1, the airflow will easily generate condensate when it accumulates in the above-mentioned positions. After a large amount of condensate accumulates, it will fall into the bottom of the furnace body 1. This part of the water will react with the raw materials, thereby affecting the quality of the flux product.

[0046] In this embodiment, the first hygrometer is used to detect the humidity above the interior of the furnace body 1, which is recorded as the furnace top humidity; the second hygrometer is used to detect the humidity inside the extraction pipe 23, which is recorded as the extraction humidity. In use, the working power of the vacuum pump can be controlled according to the above-mentioned furnace top humidity and extraction humidity, thereby avoiding the accumulation of airflow in the inlet area of ​​the extraction pipe 23.

[0047] In other words, by setting a first hygrometer and a second hygrometer, the working power of the vacuum pump can be controlled according to the humidity of the furnace top measured by the first hygrometer and the humidity of the exhaust gas measured by the second hygrometer, so as to avoid the problem of water mist or water droplets forming in the inlet area of ​​the exhaust gas flow due to the accumulation of the exhaust gas flow in the inlet area of ​​the exhaust pipe 23.

[0048] In some optional embodiments of the present invention, the cover 2 and the furnace body 1 are connected by bolts. Specifically, the joint between the cover 2 and the furnace body 1 is provided with corresponding threaded holes, the bolts are adapted to the threaded holes, and the bolt connection structure is simple and easy to operate.

[0049] In some embodiments of the present invention, the corrosion-resistant vacuum reactor for remelting flux further includes a heating element disposed inside the furnace body 1 for heating the raw materials inside the furnace body 1.

[0050] In some embodiments of the present invention, the heating component is an induction heating coil, which provides uniform heating and high heating efficiency, enabling the raw materials to be heated quickly and evenly.

[0051] In some embodiments of the present invention, a corrosion-resistant vacuum reactor for remelting flux is used to prepare flux for aluminum and aluminum alloys. For example, during the casting of aluminum and aluminum alloys, a flux for aluminum and aluminum alloys with NaCl-MgCl2-KCl as its main components is used for refining to remove impurities such as hydrogen, oxides, and alkali metals. In use, the cover 2 is first opened, and the raw material is added into the furnace body 1 through the opening of the furnace body 1; then the cover 2 is placed over the opening of the furnace body 1 to seal the furnace body 1; next, the air inside the furnace body 1 is extracted through the evacuation pipe 23 to obtain a vacuum environment; then, the raw material inside the furnace body 1 is heated by the heating element. The raw material reacts in a vacuum environment, which effectively isolates the magnesium chloride in the raw material from reacting with the moisture in the air. The amount of magnesium oxide and hydrochloric acid corrosive gas generated during the preparation process is small, thereby reducing the magnesium oxide content in the finished flux; and during the heating process, the hydrochloric acid gas inside the furnace body 1 is discharged through the evacuation pipe 23, which can prevent damage to the furnace body 1 caused by the hydrochloric acid corrosive gas. After the raw materials have melted and become remelted flux, the furnace body 1 is evacuated by opening the vent pipe 11, so that the furnace body 1 is no longer in a vacuum state. Then, the remelted flux is extracted to the outside for cooling and crushing through the discharge pipe 22. If the sealing ring 3 fails, the heat is transferred to the heat-conducting strip 9 at the point of seal failure. The heat of the heat-conducting strip 9 at this location is collected in the corresponding phase change material 4. Then, the phase change material 4 heats the shape memory alloy 5 at the corresponding location, causing the shape memory alloy 5 at that location to deform, exposing the electronic tag 8 on the shape memory alloy 5 at that location. This tag can be read by an external electronic tag reader, thereby identifying the seal failure and the location of the failure.

[0052] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
