Description

Technical Field

[0001] This utility model relates to the field of tantalum powder production technology, specifically a tantalum powder production cooling device. Background Technology

[0002] In the tantalum powder production process, the main purpose of cooling is to rapidly reduce the temperature of the tantalum powder to prevent oxidation, agglomeration, or deterioration due to high temperatures. At the same time, cooling also helps improve the dispersibility and flowability of the tantalum powder, facilitating subsequent processing and use.

[0003] The principle of tantalum powder production cooling equipment is mainly based on heat exchange mechanisms such as heat conduction, convection and radiation. Through specific equipment design and operation procedures, rapid and uniform cooling of tantalum powder can be achieved.

[0004] Existing tantalum powder production cooling devices often result in poor cooling effects due to uneven stirring during the tantalum powder production process, leading to localized overheating or insufficient cooling. This not only affects the quality of the tantalum powder and reduces production efficiency but may also pose safety hazards. Therefore, a tantalum powder production cooling device is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, existing tantalum powder production cooling devices often result in poor cooling effects during tantalum powder production due to uneven stirring, leading to localized overheating or insufficient cooling. This not only affects the quality of tantalum powder and reduces production efficiency but may also cause safety hazards. This utility model proposes a tantalum powder production cooling device.

The tank has a cooling chamber inside. A stirring shaft is slidably installed in the center of the top cover of the cooling tank. The upper end of the stirring shaft is fixedly connected to the rotating shaft of a second motor, and the lower end extends through the top cover of the cooling tank into the tank body. Four connecting rods are fixedly installed in a circular array at the lower end of the stirring shaft. Two U-shaped stirrers are fixedly installed at the lower end of the stirring shaft through the connecting rods. A discharge pipe is fixedly installed at the bottom of the cooling tank and communicates with the inside of the cooling tank. A discharge pipe is inclined on one side of the bottom end. One end of the discharge pipe is fixedly connected to one side of the bottom end of the discharge pipe. The lifting plate moves up and down by the gear driven by the first motor meshing with the tooth groove on the support column, thereby adjusting the height of the stirring shaft so that the U-shaped stirrers can stir the tantalum powder more evenly and improve the cooling effect.

[0007] Preferably, sleeves are provided at the lower corners of the four corners of the lifting plate and fixedly installed on the top of the cooling tank. Sliding rods are slidably installed inside the sleeves and fixedly installed at the bottom of the four corners of the lifting plate. Through the cooperation of the sleeves and the sliding rods, the lifting plate can remain stable during the lifting process, avoiding shaking or tilting, and ensuring the uniformity and safety of tantalum powder during the cooling process.

[0008] Preferably, a gas storage tank is fixedly installed on one side of the outside of the cooling tank, and an air inlet pipe is fixedly connected to the top of the air storage tank. The other end of the air inlet pipe is fixedly connected to the upper side of the cooling tank and communicates with the inside of the cooling tank. A pressure control valve is installed in the air inlet pipe. Through the pressure control valve, the gas pressure in the air inlet pipe can be precisely adjusted, thereby controlling the flow rate and speed of the inert gas and ensuring that the tantalum powder is cooled evenly and fully.

[0009] Preferably, a liquid outlet pipe is fixedly connected to the lower end of one side of the cooling tank, and a liquid inlet pipe is fixedly connected to the upper end of the other side. Both the liquid inlet pipe and the liquid outlet pipe are connected to the cooling chamber.

[0010] Preferably, a third motor is fixedly installed at the bottom of the feeding pipe, and an auger is rotatably installed inside the feeding pipe. The rotating shaft of the third motor is fixedly connected to the lower end of the auger. By driving the auger to rotate through the third motor, continuous and uniform feeding of tantalum powder can be achieved, which improves production efficiency and prevents tantalum powder from clogging or accumulating during the feeding process.

[0011] Preferably, a groove is provided on one side of the lower end of the discharge pipe, and a sealing plate is slidably installed inside the groove. By sliding the sealing plate, the opening and closing state of the discharge pipe can be flexibly controlled, thereby achieving precise control of tantalum powder discharge.

[0012] The advantages of this utility model are:

[0013] 1. This utility model involves feeding high-temperature tantalum powder into a cooling tank through a feed pipe during the tantalum powder production cooling process. The feed pipe is then closed, and coolant is injected into the cooling chamber through a liquid inlet pipe until the chamber is full. The coolant is then discharged through a liquid outlet pipe, allowing it to circulate within the cooling chamber to cool the tantalum powder. Simultaneously, a second motor is activated to rotate a stirring shaft. This shaft, via a connecting rod, drives a U-shaped stirrer to rotate, further agitating the tantalum powder. Simultaneously, a first motor is activated to rotate a rotating shaft. This shaft drives a gear, which, via a support column, moves a lifting plate up and down. Simultaneously, the lifting plate moves a sliding rod up and down within a sleeve. The U-shaped agitator moves up and down inside the cooling tank, allowing it to fully agitate the tantalum powder within the cooling chamber. This ensures thorough contact and uniform cooling between the tantalum powder and the tank interior. This design enables precise control and optimization of the tantalum powder production cooling process. It solves the problem of poor cooling performance, localized overheating, or insufficient cooling often caused by uneven agitation in existing tantalum powder production cooling devices. This not only affects the quality of the tantalum powder and reduces production efficiency but also poses potential safety hazards. The U-shaped agitator not only improves cooling and production efficiency but also enhances the stability and durability of the equipment. Attached Figure Description

[0022] Please see Figure 1-5As shown, a tantalum powder production cooling device includes a cooling tank 1; a support column 3 is fixedly installed on one side of the top of the cooling tank 1, and multiple toothed grooves are opened on one side of the support column 3. A lifting plate 5 is slidably installed on the support column 3. A second motor 11 is fixedly installed on one side of the upper part of the lifting plate 5. A support 7 is provided between the second motor 11 and the support column 3 and is fixedly installed on the lifting plate 5. A rotating shaft 9 is rotatably installed inside the support 7. A gear 10 is fixedly installed in the middle of the rotating shaft 9. A first motor 8 is fixedly installed on one side of the support 7. The rotating shaft of the first motor 8 is fixedly connected to one end of the rotating shaft 9. The teeth of the gear 10 mesh with the grooves of the support column 3. A feed pipe 2 is fixedly installed on the other side of the top of the cooling tank 1. A cooling chamber is opened inside the tank body of the cooling tank 1. A stirring shaft 12 is slidably installed in the center of the top cover of the cooling tank 1. The upper end of the stirring shaft 12 is fixedly connected to the rotating shaft of the second motor 11, and the lower end extends through the top cover of the cooling tank 1 into the tank body. Four connecting rods 13 are fixedly installed in a circular array at the lower end of the stirring shaft 12. Two U-shaped stirrers 14 are fixedly installed at the lower end of the stirring shaft 12 through the connecting rods 13. A discharge pipe is fixedly installed at the bottom of the cooling tank 1. 20. The feeding pipe 20 is connected to the interior of the cooling tank 1, and a discharge pipe 21 is inclinedly arranged on one side of the bottom end. One end of the discharge pipe 21 is fixedly connected to one side of the bottom end of the feeding pipe 20. During operation, in the cooling process of tantalum powder production, high-temperature tantalum powder is fed into the cooling tank 1 through the feeding pipe 2, and then the feeding pipe 2 is closed. Coolant is injected into the cooling chamber through the liquid inlet pipe 15 to fill the cooling chamber. Then the coolant is discharged through the liquid outlet pipe 16, so that the coolant circulates in the cooling chamber to cool the tantalum powder. At the same time, the second motor 11 is started to drive the stirring shaft 12 to rotate. The stirring shaft 12 is connected to the... Rod 13 drives U-shaped stirrer 14 to rotate, stirring tantalum powder. At the same time, the first motor 8 is started to drive the rotating shaft 9 to rotate. The rotating shaft 9 drives gear 10 to rotate. Gear 10 drives lifting plate 5 to move up and down through support column 3. At the same time, lifting plate 5 drives slide rod 6 to slide up and down in sleeve 4, and drives stirring shaft 12 to move up and down inside cooling tank 1. This allows U-shaped stirrer 14 to fully stir tantalum powder in cooling chamber, ensuring full contact and uniform cooling between tantalum powder and the inside of cooling tank 1. After cooling is completed, tantalum powder is discharged from cooling tank 1 through feeding pipe 20 and discharge pipe 21.

[0023] Each of the four corners of the lifting plate 5 is provided with a sleeve 4 fixedly installed on the top of the cooling tank 1. A sliding rod 6 is slidably installed inside the sleeve 4. The sliding rod 6 is fixedly installed at the bottom of the four corners of the lifting plate 5 respectively. During operation, in the cooling process of tantalum powder production, the first motor 8 is started to drive the rotating shaft 9 to rotate. The rotating shaft 9 drives the gear 10 to rotate. The gear 10 drives the lifting plate 5 to slide up and down along the support column 3 through the tooth groove on the support column 3 to adjust the height of the lifting plate 5. During the movement of the lifting plate 5, the sliding rods 6 at the bottom of its four corners slide inside the sleeve 4 to ensure that the lifting plate 5 moves up and down stably and smoothly.

[0024] A gas storage tank 18 is fixedly installed on one side of the exterior of the cooling tank 1. An air inlet pipe 17 is fixedly connected to the top of the gas storage tank 18. The other end of the air inlet pipe 17 is fixedly connected to the upper side of the cooling tank 1 and communicates with the interior of the cooling tank 1. A pressure control valve 19 is installed inside the air inlet pipe 17. During operation, when it is necessary to inject inert gas into the cooling tank 1 during the cooling process of tantalum powder production, the pressure control valve 19 is opened, and the inert gas enters the cooling tank 1 from the gas storage tank 18 through the air inlet pipe 17. By adjusting the opening of the pressure control valve 19, the flow rate and pressure of the inert gas can be precisely controlled, thereby achieving precise control of the cooling process.

[0025] The cooling tank 1 has an outlet pipe 16 fixedly connected to the lower end of one side and an inlet pipe 15 fixedly connected to the upper end of the other side. Both the inlet pipe 15 and the outlet pipe 16 are connected to the cooling chamber. During operation, in the cooling process of tantalum powder production, the coolant enters the cooling chamber through the inlet pipe 15, absorbs the heat of the tantalum powder, and is discharged through the outlet pipe 16. By adjusting the flow rate of the inlet pipe 15 and the outlet pipe 16, the cooling process can be controlled to meet different cooling requirements.

[0026] A third motor 22 is fixedly installed at the bottom of the feeding pipe 20, and an auger 23 is rotatably installed inside the feeding pipe 20. The rotating shaft of the third motor 22 is fixedly connected to the lower end of the auger 23. During operation, when the tantalum powder is cooled during production, the third motor 22 is started when discharge is required. The rotating shaft of the third motor 22 drives the auger 23 to rotate. The auger 23 enables the tantalum powder to be continuously and evenly transported into the discharge pipe 21, which not only improves the discharge efficiency but also avoids the blockage and accumulation of tantalum powder during the feeding process.

[0027] A groove is provided on one side of the lower end of the discharge pipe 21, and a sealing plate 24 is slidably installed inside the groove. During operation, when the tantalum powder is cooled during production, the sliding sealing plate 24 opens the discharge pipe 21 when discharge is required; when discharge is not required, the sliding sealing plate 24 closes the discharge pipe 21, ensuring the flexibility and controllability of the discharge process, while preventing leakage and waste of tantalum powder.

[0028] Working principle: During the cooling process of tantalum powder production, high-temperature tantalum powder is fed into the cooling tank 1 through the feed pipe 2. Then, the feed pipe 2 is closed, and coolant is injected into the cooling chamber through the liquid inlet pipe 15 until the cooling chamber is full. The coolant is then discharged through the liquid outlet pipe 16, allowing the coolant to circulate within the cooling chamber to cool the tantalum powder. Simultaneously, the second motor 11 is started to drive the stirring shaft 12 to rotate. The stirring shaft 12 drives the U-shaped stirrer 14 to rotate through the connecting rod 13, stirring the tantalum powder. At the same time, the first motor 8 is started to drive the rotating shaft 9 to rotate. The rotating shaft 9 drives the gear 10 to rotate, and the gear 10 drives the lifting plate 5 to move up and down through the support column 3. Simultaneously, the lifting plate 5 drives the sliding rod 6 to slide up and down inside the sleeve 4, and at the same time drives the stirring shaft 12 to move up and down inside the cooling tank 1, so that the U-shaped stirrer 14 can fully stir the tantalum powder in the cooling chamber. The pressure control valve 19 is opened, and inert gas enters the cooling tank 1 from the gas storage tank 18 through the air inlet pipe 17, ensuring that the tantalum powder is in full contact with the tank body and inert gas inside the cooling tank 1 and is cooled evenly. After cooling is completed, the sliding sealing plate 24 opens the discharge pipe 21 and starts the third motor 22. The rotating shaft of the third motor 22 drives the auger 23 to rotate, and the auger 23 carries the tantalum powder to the discharge pipe 21, through which the tantalum powder is discharged from the cooling tank 1.
