Description

Technical Field

[0001] This invention relates to the field of sponge titanium production technology, specifically to a smart cooling device and cooling method for low-density sponge titanium. Background Technology

[0002] Titanium and titanium alloys have the characteristics of high strength and corrosion resistance, and are used in aerospace, deep-sea exploration, chemical and medical fields. Sponge titanium is an important raw material for titanium alloy processing. After the reduction distillation and purification process, the temperature of sponge titanium is above 900℃. The sponge titanium agglomerate after the high-temperature distillation must be cooled to room temperature before it can be taken out and enter the subsequent production process.

[0003] In the production of titanium sponge, the traditional cooling method involves suspending a high-temperature reactor containing titanium sponge lumps into a cooling water jacket, introducing indirect water first, then direct water, and maintaining positive argon pressure protection within the reactor throughout the cooling process. However, when this operation is performed manually, argon replenishment is often delayed due to operator negligence, leading to gas ingress into the product. Severe gas ingress results in the scrapping of the entire batch. While computer-controlled intelligent operation is possible, the high temperatures (above 900°C) during titanium sponge production make precision electronic components highly susceptible to damage after a period of use, resulting in a high failure rate. Furthermore, existing cooling devices cannot adjust the flow rate and velocity of the cooling circulating water. Given the low thermal conductivity of titanium sponge, the surface of the high-temperature titanium sponge lumps experiences severe rapid cooling and contraction during the cooling process, leading to increased density and ultimately affecting product quality.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a low-density sponge titanium intelligent cooling device and its cooling method. Summary of the Invention

[0005] The purpose of this invention is to provide a low-density titanium sponge intelligent cooling device and its cooling method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a low-density titanium sponge intelligent cooling device and its cooling method, comprising a cooling water jacket, a reaction component, and a pressure regulating component. The cooling water jacket has a water flow channel on its inner side, and a first water inlet pipe is connected to the outer left side of the cooling water jacket. A second water inlet pipe is connected to the outer bottom of the first water inlet pipe. A first water outlet pipe is connected to the bottom right side of the cooling water jacket, and a first drainage component is provided at the outer top of the first water outlet pipe. A second drainage component is provided at the outer top of the first drainage component. A cover is connected to the outer top of the cooling water jacket, and the reaction component is disposed at the bottom of the cover. The reaction component includes a reaction... The reaction vessel comprises a dish, a first heat-conducting rod, a first heat-conducting plate, a second heat-conducting rod, a second heat-conducting plate, a sieve plate, and a connecting sleeve. The first heat-conducting rod is located at the inner middle of the dish, and its outer end is connected to the first heat-conducting plate. A second heat-conducting rod is located on the inner right side of the dish, and its outer end is connected to the second heat-conducting plate.

[0007] Furthermore, the first drainage component includes a second water outlet pipe, a first heat insulation frame, a first heat-conducting layer, a first partition, a first water channel, a first thermal expansion water bladder, a first push block, and a second water channel. The inner side of the second water outlet pipe is connected to the first heat insulation frame, and the inner side of the first heat insulation frame is connected to the first heat-conducting layer. The inner side of the second water outlet pipe is provided with a first partition, and the inner side of the first partition is provided with a first water channel. The inner right side of the second water outlet pipe is provided with a first thermal expansion water bladder, and the outer end of the first thermal expansion water bladder is connected to a first push block. The inner side of the first push block is provided with a second water channel.

[0008] Furthermore, the first heat insulation frame wraps around the outer end of the first heat-conducting layer, and the first heat-conducting layer is in contact with the first heat-conducting plate, and the first heat-conducting layer is in contact with the first thermal expansion water bladder.

[0009] Furthermore, the first thermal expansion water bladder forms a fully enclosed structure through the second water outlet pipe, the first partition, the first push block, and the first heat-conducting layer, and the first thermal expansion water bladder is fixedly connected to the first push block.

[0010] Furthermore, the second drainage assembly includes a third outlet pipe, a second heat insulation frame, a second heat-conducting layer, a second partition, a sealing block, a second thermal expansion water bladder, and a second push block. The inner side of the third outlet pipe is connected to the second heat insulation frame, and the inner side of the second heat insulation frame is provided with the second heat-conducting layer. The middle inner side of the third outlet pipe is provided with the second partition, and the inner left side of the third outlet pipe is provided with the sealing block. The inner right side of the third outlet pipe is provided with the second thermal expansion water bladder, and the outer end of the second thermal expansion water bladder is connected to the second push block.

[0011] Furthermore, the second thermal expansion water bladder is fixedly connected to the second push block, and the outer surface of the second push block is in contact with the inner surface of the third water outlet pipe and the sealing block.

[0012] Furthermore, the pressure regulating assembly includes a third heat-conducting plate, a third thermal expansion water bladder, a temperature-insulating plate, a conductive base, a first energizing contact, a second energizing contact, a first energizing base, a first conductive wire, a first pressure regulating valve, a second energizing base, a second conductive wire, and a second pressure regulating valve. The third thermal expansion water bladder is located on the outer top of the third heat-conducting plate, and a temperature-insulating plate is located on the outer top of the third thermal expansion water bladder. A conductive base is located on the outer top of the temperature-insulating plate. The first energizing contact is connected to the outer top of the conductive base, and a second energizing contact is located on the outer front part of the conductive base. The first energizing base is connected to the outer top of the cover, and a first conductive wire is connected to the outer end of the first energizing base. A first pressure regulating valve is located on the left inner side of the cover, a second energizing base is located on the inner side of the cover, and a second conductive wire is connected to the outer end of the second energizing base. A second pressure regulating valve is located on the right inner side of the cover.

[0013] Furthermore, the third heat-conducting plate is fixedly connected to the first heat-conducting rod, and the third heat-conducting plate is in close contact with the third thermal expansion water bladder.

[0014] Furthermore, the argon gas storage tank is connected to a connecting pipe via a pressure equalization valve, and the connecting pipe is connected to a sieve plate via a connecting sleeve, and the sieve plate is connected to the inside of the reaction vessel.

[0015] Furthermore, the cooling method of the low-density titanium sponge smart cooling device includes the following steps:

[0016] S1: The reaction vessel containing the titanium sponge is hoisted to the inside of the cooling water jacket, so that the cover is in contact with the top surface of the cooling water jacket. At the same time, the connecting sleeve is connected to the connecting pipe. In addition, the staff pours clean water into the second water inlet pipe, so that the clean water enters the interior of the cooling water jacket and contacts the outer surface of the reaction vessel. This allows the clean water to cool and reduce the titanium sponge in the reaction vessel through heat transfer.

[0017] S2: The first heat-conducting rod conducts the temperature of the center part of the titanium sponge to the first heat-conducting layer through the first heat-conducting plate. Because the first heat-conducting layer is in contact with the first thermal expansion water bladder, when the temperature of the center part of the titanium sponge is high, the high temperature is conducted to the first thermal expansion water bladder through the first heat-conducting layer. After receiving the heat, the water inside the first thermal expansion water bladder boils, causing the first thermal expansion water bladder to expand. After the first thermal expansion water bladder expands, it pushes the first push block to move, which connects the first water channel and the second water channel, opening the first drainage component. At this time, the cooling water enters the cooling water jacket from the second water inlet pipe and is discharged from the first drainage component. The first drainage component is located in the lower middle part of the cooling water jacket, which allows the equipment to cool the titanium sponge at a lower cooling rate.

[0018] S3: After the sponge titanium block is slowly cooled to reduce the temperature of its center and outer ends, the temperature transferred from the first heat-conducting layer to the first thermal expansion water bladder also decreases. This reduces the expansion amplitude of the first thermal expansion water bladder, causing the first push block to move to a position offset from the first and second water channels. This closes the first drainage component. Similarly, the temperature transferred from the second heat-conducting layer to the second thermal expansion water bladder also decreases, causing the second push block to contract with the second thermal expansion water bladder, separating the contacting second push block and sealing block. This opens the second drainage component. Through the above operations, the equipment automatically switches to high water level mode for cooling after the temperature of the sponge titanium block decreases.

[0019] S4: The argon storage tank supplies argon gas to the bottom of the sieve plate through the connecting pipe and the connecting sleeve. The sieve plate is connected to the reaction vessel, which allows the argon gas to rise from the bottom of the titanium sponge to the entire reaction vessel, thus providing argon protection for the titanium sponge. The vent pipe continuously supplies argon gas into the argon storage tank, ensuring that the argon gas in the tank is always full. At the same time, the gas pressure in the argon storage tank can be adjusted to 0.03-0.05MPa. During the cooling process of the titanium sponge, the second pressure regulating valve works to adjust the gas pressure in the reaction vessel to 0.03-0.05MPa. When the pressure in the reaction vessel is lower than the lower limit, the pressure equalization valve automatically opens due to the pressure difference, which enables the argon storage tank to automatically replenish argon gas.

[0020] S5: When the center of the titanium sponge is at a high temperature, the high temperature is transferred to the third thermal expansion water bladder through the third heat conduction plate. This causes the third thermal expansion water bladder to expand. After the third thermal expansion water bladder expands, the heat insulation plate moves the conductive seat upward. This causes the conductive seat to disconnect the second energized contact from the second energized seat and connect the first energized contact to the first energized seat. This causes the equipment to de-energize the second pressure regulating valve and energize the first pressure regulating valve. The pressure regulating range of the first pressure regulating valve is 0.015-0.03MPa. At this time, the vent pipe can also adjust the pressure in the argon storage tank to 0.15-0.03MPa. By reducing the argon pressure in the titanium sponge at high temperature, the influence of argon pressure on the density of the high-temperature titanium sponge is effectively reduced.

[0021] This invention provides a low-density titanium sponge intelligent cooling device and its cooling method, which has the following beneficial effects:

[0022] 1. In this invention, the first heat-conducting rod contacts the center of the titanium sponge, allowing it to conduct the temperature of the center of the titanium sponge to the first heat-conducting layer via the first heat-conducting plate. Because the first heat-conducting layer is in contact with the first thermal expansion water bladder, when the temperature of the center of the titanium sponge is high, the high temperature can be conducted to the first thermal expansion water bladder via the first heat-conducting layer. Upon receiving heat, the water inside the first thermal expansion water bladder boils, causing it to expand. After expansion, the first thermal expansion water bladder can push the first pusher block to move. This allows the first and second water channels to connect, enabling the first drainage component to open. At this time, cooling water enters the cooling water jacket from the second inlet pipe and exits from the first drainage component, which is located in the lower middle part of the cooling water jacket. This allows the equipment to cool the sponge titanium agglomerate at a relatively low cooling rate. Through the above operations, the central part of the sponge titanium agglomerate, which has a low heat conduction rate, can be slowly cooled. This effectively reduces the shrinkage of the titanium agglomerate after cooling, thereby reducing the density of the sponge titanium encapsulation.

[0023] 2. In this invention, after the sponge titanium bulge undergoes slow cooling to reduce the temperature of its center and outer ends, the temperature transferred from the first heat-conducting layer to the first thermal expansion water bladder also decreases. This reduces the expansion amplitude of the first thermal expansion water bladder, causing the first pusher block to shift to a position offset from the first and second water channels, allowing the first drainage component to close. Similarly, the temperature transferred from the second heat-conducting layer to the second thermal expansion water bladder also decreases, causing the second pusher block to contract with the second thermal expansion water bladder, separating the contacting second pusher block and sealing block. This allows the second drainage component to open. Through these operations, the equipment can automatically switch to a high water level mode after the temperature of the sponge titanium bulge decreases. This ensures that while reducing the density of the sponge titanium encapsulation, the cooling rate of the sponge titanium bulge is accelerated as much as possible, preventing the slow cooling rate from affecting production efficiency. Furthermore, the above operations do not require manual operation and eliminate the need for computer intelligent operation, thus avoiding the drawbacks of untimely manual operation and the malfunctions of computer intelligent operation.

[0024] 3. During the cooling process of the titanium sponge in the reaction vessel of this invention, the argon storage tank can input argon gas to the bottom of the sieve plate through the connecting pipe and the connecting sleeve. The sieve plate is connected to the reaction vessel, which allows argon gas to rise from the bottom of the titanium sponge to the entire reaction vessel, thus achieving argon protection for the titanium sponge. The vent pipe can continuously input argon gas into the argon storage tank, ensuring that the argon gas in the argon storage tank is always in a full state. At the same time, the gas pressure in the argon storage tank can be adjusted to 0.03-0.05 MPa. During the cooling process of the titanium sponge, the second pressure regulating valve works, which can adjust the gas pressure in the reaction vessel to 0.03-0.05 MPa. When the pressure in the reaction vessel is lower than the lower limit, the pressure equalization valve can automatically open due to the pressure difference, which allows the argon storage tank to automatically replenish argon gas. This can effectively avoid the problem of gas entering the product due to untimely argon filling.

[0025] 4. When the central part of the titanium sponge is at a high temperature, the high temperature can be transferred to the third thermal expansion water bladder through the third heat-conducting plate. This allows the third thermal expansion water bladder to expand. After the third thermal expansion water bladder expands, it can cause the heat insulation plate to move the conductive seat upward. This allows the conductive seat to disconnect the second energized contact from the second energized seat and connect the first energized contact to the first energized seat. This allows the device to de-energize the second pressure regulating valve and energize the first pressure regulating valve. The pressure regulating range of the first pressure regulating valve is 0.015-0.03 MPa. At this time, the vent pipe can also adjust the pressure in the argon storage tank to 0.015-0.03 MPa. By reducing the argon pressure in the titanium sponge at high temperature, the influence of argon pressure on the density of the high-temperature titanium sponge can be effectively reduced.

An argon gas storage tank 11 is installed at the outer bottom of the cooling water jacket 1, and a vent pipe 12 is connected to the outer right side of the argon gas storage tank 11. A pressure equalizing valve 13 is provided on the outer top of the argon gas storage tank 11, and a connecting pipe 14 is provided at the top of the pressure equalizing valve 13.

[0033] Please see Figures 1 to 3The first drainage component 6 includes a second water outlet pipe 601, a first heat insulation frame 602, a first heat-conducting layer 603, a first partition 604, a first water channel 605, a first thermal expansion water bladder 606, a first push block 607, and a second water channel 608. The inner side of the second water outlet pipe 601 is connected to the first heat insulation frame 602, and the inner side of the first heat insulation frame 602 is connected to the first heat-conducting layer 603. The inner side of the second water outlet pipe 601 is provided with the first partition 604, and the inner side of the first partition 604 has a first channel. The water tank 605 has a first thermal expansion water bladder 606 located on the right side inside the second water outlet pipe 601. A first push block 607 is connected to the outer end of the first thermal expansion water bladder 606. A second water channel 608 is formed on the inner side of the first push block 607. A first heat insulation frame 602 wraps around the outer end of a first heat-conducting layer 603, and the first heat-conducting layer 603 is in close contact with the first heat-conducting plate 903. The first heat-conducting layer 603 is also in close contact with the first thermal expansion water bladder 606. The first thermal expansion water bladder 606 is connected to the second water outlet pipe. 601, the first partition 604, the first push block 607, and the first heat-conducting layer 603 form a fully enclosed structure, and the first thermal expansion water bladder 606 is fixedly connected to the first push block 607. The second drainage assembly 7 includes a third water outlet pipe 701, a second heat insulation frame 702, a second heat-conducting layer 703, a second partition 704, a sealing block 705, a second thermal expansion water bladder 706, and a second push block 707. The inner side of the third water outlet pipe 701 is connected to the second heat insulation frame 702, and the inner side of the second heat insulation frame 702 is provided with... The second heat-conducting layer 703, the inner middle of the third water outlet pipe 701 is provided with a second partition 704, and the inner left side of the third water outlet pipe 701 is provided with a sealing block 705. The inner right side of the third water outlet pipe 701 is provided with a second thermal expansion water bladder 706, and the outer end of the second thermal expansion water bladder 706 is connected with a second push block 707. The second thermal expansion water bladder 706 and the second push block 707 are fixedly connected, and the outer surface of the second push block 707 is in contact with the inner surface of the third water outlet pipe 701 and the sealing block 705.

[0034] The specific operation is as follows: After the reduction reaction is completed, the operator hoists the reaction vessel 901 containing the sponge titanium agglomerate to the inside of the cooling water jacket 1, ensuring that the cover 8 fits against the top surface of the cooling water jacket 1 and that the connecting sleeve 907 connects with the connecting pipe 14. Furthermore, the operator pours clean water into the second water inlet pipe 4, allowing the water to enter the interior of the cooling water jacket 1 and contact the outer surface of the reaction vessel 901. This allows the water to cool and reduce the sponge titanium agglomerate inside the reaction vessel 901 through heat transfer. The sieve plate 906 is placed at the bottom of the reaction vessel 901. After the reduction process, the sponge titanium agglomerate is formed on the sieve plate 906. After the reaction vessel 901 is hoisted to the inside of the cooling water jacket 1, the first heat-conducting plate 903 and the second heat-conducting plate 905 at its outer end... The first heat-conducting rod 902 is in contact with the first heat-conducting layer 603 and the second heat-conducting layer 703, respectively. It also contacts the center of the titanium sponge, allowing the first heat-conducting rod 902 to conduct the temperature of the center of the titanium sponge to the first heat-conducting layer 603 via the first heat-conducting plate 903. Because the first heat-conducting layer 603 is in contact with the first thermal expansion water bladder 606, when the temperature of the center of the titanium sponge is high, the high temperature is conducted to the first heat-conducting layer 603, and then further conducted to the first thermal expansion water bladder 606. Upon receiving heat, the water inside the first thermal expansion water bladder 606 boils, causing it to expand. After expansion, the first thermal expansion water bladder 606 can push the first pusher block. Displacement of 607 allows the first water channel 605 and the second water channel 608 to connect. This connection enables the first drainage component 6 to open, allowing cooling water to enter the cooling water jacket 1 from the second inlet pipe 4 and exit through the first drainage component 6. The first drainage component 6 is located in the lower middle part of the cooling water jacket 1, allowing the equipment to cool the titanium sponge at a lower rate. This slow cooling of the central part of the titanium sponge, with its lower heat conduction rate, significantly reduces the shrinkage of the titanium sponge after cooling, thus lowering the encapsulation density. The slow cooling of the titanium sponge allows the temperature of its central part to reach a certain level. After the external temperature decreases, the temperature transferred from the first heat-conducting layer 603 to the first thermal expansion water bladder 606 also decreases. This reduces the expansion amplitude of the first thermal expansion water bladder 606, causing the first pusher block 607 to shift to a position offset from the first water channel 605 and the second water channel 608. This allows the first drainage component 6 to close. Similarly, the temperature transferred from the second heat-conducting layer 703 to the second thermal expansion water bladder 706 also decreases. This allows the second pusher block 707 to contract with the second thermal expansion water bladder 706, separating the contacting second pusher block 707 and sealing block 705. This allows the second drainage component 7 to open. Through these operations, the equipment can automatically switch to high water level mode after the temperature of the titanium sponge decreases.This ensures that while reducing the density of the titanium sponge encapsulation, the cooling rate of the titanium sponge agglomerate is accelerated as much as possible, preventing slow cooling from affecting production efficiency. The above operations require no manual intervention and eliminate the need for computer-aided operation, avoiding the drawbacks of untimely manual operation and malfunctions prone to occur in computer-aided operation. Because the first heat insulation frame 602 can enclose the first heat-conducting layer 603, and the first thermal expansion water bladder 606 forms a fully enclosed structure through the second water outlet pipe 601, the first partition 604, the first push block 607, and the first heat-conducting layer 603, this effectively prevents the cooling water from affecting the heat conduction from the first heat insulation frame 602 to the first thermal expansion water bladder 606, thus effectively ensuring the thermal conductivity accuracy of the equipment. Furthermore, after the second drainage component 7 is opened, by opening the first water inlet pipe 3 and the first water outlet pipe 5, clean water can flow inside the water tank 2. This allows the water in the water tank 2 to indirectly cool the water in the cooling water jacket 1, achieving a better cooling effect.

[0035] Please see Figures 4 to 5 The pressure regulating component includes a third heat-conducting plate 1001, a third thermal expansion water bladder 1002, a temperature-insulating plate 1003, a conductive base 1004, a first energized contact 1005, a second energized contact 1006, a first energized base 1007, a first conductive wire 1008, a first pressure regulating valve 1009, a second energized base 1010, a second conductive wire 1011, and a second pressure regulating valve 1012. The third thermal expansion water bladder 1002 is provided on the top outer side of the third heat-conducting plate 1001, and the temperature-insulating plate 1003 is provided on the top outer side of the third thermal expansion water bladder 1002. The conductive base 1004 is provided on the top outer side of the temperature-insulating plate 1003. A first energizing contact 1005 is connected to the top outer side of the conductive base 1004, and a second energizing contact 1006 is provided on the front outer side of the conductive base 1004. A first energizing base 1007 is connected to the top outer side of the cover 8, and a first conductive wire 1008 is connected to the outer end of the first energizing base 1007. A first pressure regulating valve 1009 is provided on the left side inside the cover 8, and a second energizing base 1010 is provided on the inner side of the cover 8. The end is connected to a second conductive wire 1011. A second pressure regulating valve 1012 is provided on the right side inside the cover 8. The third heat-conducting plate 1001 is fixedly connected to the first heat-conducting rod 902, and the third heat-conducting plate 1001 and the third thermal expansion water bag 1002 are in close contact with each other. The argon storage tank 11 is connected to the connecting pipe 14 through the equalizing valve 13, and the connecting pipe 14 is connected to the sieve plate 906 through the connecting sleeve 907. The sieve plate 906 is connected to the inside of the reaction vessel 901.

[0036] The specific operation is as follows: During the cooling process of the titanium sponge in reaction vessel 901, the argon storage tank 11 can input argon gas to the bottom of the sieve plate 906 through the connection between the connecting pipe 14 and the connecting sleeve 907. The sieve plate 906 is connected to the reaction vessel 901, which allows the argon gas to rise from the bottom of the titanium sponge to the entire reaction vessel, thus achieving argon gas protection for the titanium sponge. Meanwhile, the vent pipe 12 can continuously input argon gas into the argon storage tank 11, ensuring that the argon gas in the argon storage tank 11 is always kept at a constant level. In the fully charged state, the pressure inside the argon storage tank 11 can be adjusted to 0.03-0.05 MPa. During the cooling process of the sponge titanium block, the second pressure regulating valve 1012 operates, adjusting the pressure inside the reaction vessel 901 to 0.03-0.05 MPa. When the pressure inside the reaction vessel 901 falls below the lower limit, the equalizing valve 13 automatically opens due to the pressure difference. This allows the argon storage tank 11 to automatically replenish argon, effectively preventing product defects caused by untimely argon filling. Regarding the gas issue, when the center of the titanium sponge is at a high temperature, the high temperature can be transferred to the third thermal expansion water bladder 1002 through the third heat-conducting plate 1001. This allows the third thermal expansion water bladder 1002 to expand. After the third thermal expansion water bladder 1002 expands, it can cause the heat insulation plate 1003 to move the conductive base 1004 upward. This allows the conductive base 1004 to disconnect the second energized contact 1006 from the second energized base 1010 and disconnect the first energized contact 1005. Connected to the first energized base 1007, this device can de-energize the second pressure regulating valve 1012 and energize the first pressure regulating valve 1009. The pressure regulating range of the first pressure regulating valve 1009 is 0.015-0.03MPa. At this time, the vent pipe 12 can also adjust the pressure in the argon storage tank 11 to 0.015-0.03MPa. By reducing the argon pressure in the sponge titanium agglomerate at high temperature, the influence of argon pressure on the density of the high-temperature titanium agglomerate can be effectively reduced.

[0037] In summary, the low-density sponge titanium intelligent cooling device and its cooling method are as follows: First, after the reduction reaction is completed, the operator hoists the reaction vessel 901 containing the sponge titanium agglomerate to the inside of the cooling water jacket 1, so that the cover 8 fits against the top surface of the cooling water jacket 1, and the connecting sleeve 907 connects with the connecting pipe 14. In addition, the operator pours clean water into the second water inlet pipe 4, so that the clean water enters the interior of the cooling water jacket 1 and contacts the outer surface of the reaction vessel 901. This allows the clean water to cool and reduce the sponge titanium agglomerate in the reaction vessel 901 through heat transfer. The sieve plate 906 is placed at the bottom of the reaction vessel 901, and the sponge titanium agglomerate is generated on the sieve plate 906 after the reduction process is completed.

[0038] Then, after the reaction vessel 901 is hoisted into the inner side of the cooling water jacket 1, the first heat-conducting plate 903 and the second heat-conducting plate 905 at its outer end can contact the first heat-conducting layer 603 and the second heat-conducting layer 703, respectively. The first heat-conducting rod 902 contacts the center of the sponge titanium block. This allows the first heat-conducting rod 902 to conduct the temperature of the center of the sponge titanium block to the first heat-conducting layer 603 through the first heat-conducting plate 903. Because the first heat-conducting layer 603 is in contact with the first thermal expansion water bladder 606, when the temperature of the center of the sponge titanium block is high, the high temperature is conducted to the first heat-conducting layer 603, and then to the first thermal expansion water bladder 606. After receiving the heat, the water inside the first thermal expansion water bladder 606 can boil, causing the first thermal expansion water bladder 606 to expand. The first thermal expansion water bladder 606 expands, and after expansion, it can push the first push block 607 to move, which allows the first water channel 605 and the second water channel 608 to connect. After the first water channel 605 and the second water channel 608 are connected, the first drainage component 6 can be opened. At this time, cooling water enters the cooling water jacket 1 from the second water inlet pipe 4 and is discharged from the first drainage component 6. The first drainage component 6 is located in the lower middle part of the cooling water jacket 1, which allows the equipment to cool the sponge titanium bolus at a lower cooling rate. Through the above operations, the central part of the sponge titanium bolus with a low heat conduction rate can be slowly cooled, which can significantly reduce the shrinkage of the titanium bolus after cooling, thereby reducing the encapsulation density of the sponge titanium.

[0039] Next, after the sponge titanium bulge undergoes slow cooling to reduce the temperature of its center and outer ends, the temperature transferred from the first heat-conducting layer 603 to the first thermal expansion water bladder 606 also decreases. This reduces the expansion amplitude of the first thermal expansion water bladder 606, causing the first pusher block 607 to shift to a position offset from the first water channel 605 and the second water channel 608. This allows the first drainage component 6 to close. Similarly, the temperature transferred from the second heat-conducting layer 703 to the second thermal expansion water bladder 706 also decreases. This allows the second pusher block 707 to contract with the second thermal expansion water bladder 706, separating the contacting second pusher block 707 and sealing block 705. This allows the second drainage component 7 to open. Through the above operations, the equipment can automatically switch to high water level mode after the temperature of the sponge titanium bulge decreases. This ensures that the density of the sponge titanium encapsulation is reduced while accelerating the cooling speed of the sponge titanium bulge as much as possible.

[0040] Subsequently, during the cooling process of the titanium sponge in reaction vessel 901, argon gas can be introduced into the bottom of sieve plate 906 through the connection between argon gas tank 11 and connecting sleeve 907 via connecting pipe 14. Since sieve plate 906 is connected to reaction vessel 901, argon gas can rise from the bottom of titanium sponge to the entire reaction vessel, thus achieving argon gas protection for titanium sponge. Meanwhile, vent pipe 12 can continuously introduce argon gas into argon gas tank 11, ensuring that argon gas in argon gas tank 11 is always in a full state. Simultaneously, the gas pressure in the argon storage tank 11 can be adjusted to 0.03-0.05 MPa. During the cooling process of the sponge titanium block, the second pressure regulating valve 1012 works to adjust the gas pressure in the reaction vessel 901 to 0.03-0.05 MPa. When the pressure in the reaction vessel 901 is lower than the lower limit, the pressure equalization valve 13 can be automatically opened due to the pressure difference. This allows the argon storage tank 11 to automatically replenish argon, which can effectively avoid the problem of gas entering the product due to untimely argon filling.

[0041] Finally, when the center of the titanium sponge is at a high temperature, the high temperature can be transferred to the third thermal expansion water bladder 1002 through the third heat-conducting plate 1001. This allows the third thermal expansion water bladder 1002 to expand. After the third thermal expansion water bladder 1002 expands, it can cause the heat insulation plate 1003 to move the conductive base 1004 upward. This allows the conductive base 1004 to disconnect the second energized contact 1006 from the second energized base 1010, and to disconnect the first energized contact 1005 from the second energized base 1010. A power connector 1007 is connected, which allows the device to de-energize the second pressure regulating valve 1012 and energize the first pressure regulating valve 1009. The pressure regulating range of the first pressure regulating valve 1009 is 0.015-0.03MPa. At this time, the vent pipe 12 can also adjust the pressure in the argon storage tank 11 to 0.015-0.03MPa. By reducing the argon pressure in the sponge titanium agglomerate at high temperature, the influence of argon pressure on the density of the high-temperature titanium agglomerate can be effectively reduced.

8. A low-density titanium sponge intelligent cooling device according to any one of claims 1-7, characterized in that, The cooling method of this low-density titanium sponge smart cooling device includes the following steps: S1: The reaction vessel (901) containing the sponge titanium agglomerate is hoisted to the inside of the cooling water jacket (1), so that the cover (8) is in contact with the top surface of the cooling water jacket (1), and the connecting sleeve (907) is connected to the connecting pipe (14). In addition, the staff pours clean water into the second water inlet pipe (4), so that the clean water enters the interior of the cooling water jacket (1) and contacts the outer surface of the reaction vessel (901). This allows the clean water to cool and reduce the sponge titanium agglomerate in the reaction vessel (901) through heat transfer. S2: The first heat-conducting rod (902) conducts the temperature of the center part of the sponge titanium block to the first heat-conducting layer (603) through the first heat-conducting plate (903). Because the first heat-conducting layer (603) is in contact with the first thermal expansion water bladder (606), when the temperature of the center part of the sponge titanium block is at a high value, the high temperature is conducted to the first thermal expansion water bladder (606) through the first heat-conducting layer (603). After receiving the heat, the water inside the first thermal expansion water bladder (606) boils, causing the first thermal expansion water bladder (606) to enter... As the expansion occurs, the first thermal expansion water bladder (606) pushes the first push block (607) to move after expansion, which connects the first water channel (605) and the second water channel (608), opening the first drainage component (6). At this time, cooling water enters the cooling water jacket (1) from the second water inlet pipe (4) and is discharged from the first drainage component (6). The first drainage component (6) is located in the lower middle part of the cooling water jacket (1), which allows the equipment to cool the sponge titanium block at a lower cooling rate. S3: After the sponge titanium block is slowly cooled to reduce the temperature of its center and outer end, the temperature transferred from the first heat-conducting layer (603) to the first thermal expansion water bladder (606) will also decrease. This reduces the expansion amplitude of the first thermal expansion water bladder (606), causing the first push block (607) to move to a position offset from the first water channel (605) and the second water channel (608). This causes the first drainage component (6) to close. Similarly, the temperature transferred from the second heat-conducting layer (703) to the second thermal expansion water bladder (706) will also decrease. This causes the second push block (707) to contract with the second thermal expansion water bladder (706) to separate the contacting second push block (707) and sealing block (705). This causes the second drainage component (7) to open. Through the above operations, the equipment automatically switches to high water level mode for cooling after the temperature of the sponge titanium block decreases. S4: Argon gas is introduced into the bottom of the sieve plate (906) through the connection pipe (14) and the connection sleeve (907). The sieve plate (906) is connected to the reaction vessel (901), which allows the argon gas to rise from the bottom of the sponge titanium block to the entire reaction vessel, thus achieving argon gas protection for the sponge titanium block. Meanwhile, the vent pipe (12) continuously introduces argon gas into the argon gas storage tank (11), ensuring that the argon gas in the argon gas storage tank (11) is always in a constant state. In the fully charged state, the gas pressure in the argon storage tank (11) can be adjusted to 0.03-0.05MPa. During the cooling process of the sponge titanium block, the second pressure regulating valve (1012) works to adjust the gas pressure in the reaction vessel (901) to 0.03-0.05MPa. When the pressure in the reaction vessel (901) is lower than the lower limit, the pressure equalization valve (13) automatically opens due to the pressure difference, which enables the argon storage tank (11) to automatically replenish argon. S5: When the center of the titanium sponge is at a high temperature, the high temperature is transferred to the third thermal expansion water bladder (1002) through the third heat-conducting plate (1001), causing the third thermal expansion water bladder (1002) to expand. After the third thermal expansion water bladder (1002) expands, the heat insulation plate (1003) causes the conductive base (1004) to move upward. This causes the conductive base (1004) to disconnect the second energized contact (1006) from the second energized base (1010), and also disconnect the first energized contact (1006). 05) Connect to the first energized socket (1007), which de-energizes the second pressure regulating valve (1012) and energizes the first pressure regulating valve (1009). The pressure regulating range of the first pressure regulating valve (1009) is 0.015-0.03MPa. At this time, the vent pipe (12) can also adjust the pressure in the argon storage tank (11) to 0.015-0.03MPa. By reducing the argon pressure at high temperature, the influence of argon pressure on the density of the high-temperature titanium block is effectively reduced.
