[0002] Gallium is of great significance in many fields such as electronics, new energy, and aerospace. It is a key raw material for semiconductors, supports the development of photovoltaics and energy storage, and is crucial to the performance of aerospace equipment and medical diagnostics. Gallium has a melting point of 29.8℃ and is solid at room temperature. In dry environments, it easily oxidizes with oxygen to form GaO3. In related technologies, the containers used to store gallium cannot guarantee good fluidity, which is inconvenient for subsequent filling and use in subsequent production processes, making it difficult to meet subsequent production needs.

Detailed Implementation

[0044] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0045] As shown in Figures 1 to 3, a storage tank 100 is provided according to an embodiment of the present disclosure, comprising: a first housing 110 for storing liquid gallium metal; a second housing 120 sleeved on the first housing 110; a temperature regulating unit disposed between the first housing 110 and the second housing 120 for regulating the internal temperature of the first housing 110; and a valve body 140 passing through the second housing 120 and communicating with the first housing 110, through which the liquid gallium metal is released to an acid boiling tank.

[0046] It is understood that the storage tank 100 provided in this embodiment of the present disclosure is provided with a first housing 110, a second housing 120, a temperature regulating unit, and a valve body 140. Liquid gallium metal is stored in the first housing 110, and the second housing 120 is fitted over the first housing 110 to protect the first housing 110, thereby protecting the liquid gallium metal and facilitating transportation. The temperature regulating unit is disposed between the first housing 110 and the second housing 120, and regulates the internal temperature of the first housing 110 to ensure that the internal temperature of the first housing 110 is sufficient to maintain the liquid state of the gallium metal. The valve body 140 passes through the second housing 120 and communicates with the first housing 110. After the storage tank 100 is transported to a designated location, the liquid gallium metal can be released into the acid boiling tank by opening the valve body 140. With this configuration, the internal temperature of the first housing 110 is regulated by the temperature regulation unit, ensuring that the metallic gallium remains liquid during the storage and handling process in the storage tank 100. This allows for the direct release of liquid metallic gallium into the acid boiling tank without the need for additional heating processes or manual handling of the metallic gallium from the storage tank 100 to the acid boiling tank, thereby improving work efficiency, reducing labor intensity, and meeting subsequent production needs.

[0047] Understandably, as shown in Figure 1, the valve body 140 can be located slightly above the bottom of the storage tank 100 to facilitate the smooth flow of liquid gallium by its own weight. The second housing 120 can be made of metal for higher strength and improved protection. The first housing 110 can be made of a material that does not react with gallium to ensure the quality of the gallium. The internal temperature of the first housing 110 can be adjusted to 40°C to 50°C via a temperature regulating unit to maintain the gallium in a liquid state.

[0048] In some examples, as shown in FIG1, the temperature regulating unit includes: a heating plate 130 disposed at the bottom of the first housing 110; a temperature sensor for detecting the actual temperature inside the first housing 110; and a first controller for adjusting the working state of the heating plate 130 according to the actual temperature value and the preset temperature value sent by the temperature sensor.

[0049] Understandably, the temperature regulation unit may include a heating plate 130, a temperature sensor, and a first controller. Specifically, the heating plate 130 may be located at the bottom of the first housing 110, in contact with the surface of the first housing 110, to ensure uniform heating. The actual temperature inside the first housing 110 is detected by the temperature sensor, and both the heating plate 130 and the temperature sensor are electrically connected to the first controller. The user can set a preset temperature value on the first controller, and the temperature sensor sends the detected actual temperature value to the first controller. The first controller can adjust the working state of the heating plate 130 according to the actual temperature value and the preset temperature value to automatically regulate the internal temperature of the first housing 110, ensuring that the gallium metal remains in a liquid state and has good fluidity.

[0050] For example, the heating plate 130 may be a silicone heating plate 130, which can generate heat through a surface and has a power density of 0.5 W / cm². 2 Up to 2W / cm 2 Heat can be evenly transferred to the first housing 110, avoiding excessive local temperature differences caused by traditional resistance wire heating, and preventing local solidification or oxide film rupture of metallic gallium. A PT100 platinum electrothermal vibration sensor can be used as the temperature sensor. The PT100 platinum electrothermal vibration sensor is corrosion-resistant, high-precision, vibration-resistant, and durable. Furthermore, compared to traditional sensors, the resistance-temperature relationship of the PT100 platinum electrothermal vibration sensor is highly linear, facilitating accurate and rapid calculation of the output power of the heating plate 130 by the first controller, ensuring the effective temperature regulation of the heating plate 130.

[0051] In some examples, when the actual temperature value is less than the set temperature value and the difference between the actual temperature value and the preset temperature value is greater than the set difference, the first controller controls the heating plate 130 to operate at full power; when the difference between the actual temperature value and the preset temperature value is less than or equal to the set difference, the first controller adjusts the operation of the heating plate 130 through PID (Proportional-Integral-Derivative) control; when the actual temperature value is greater than the set temperature value and the difference between the actual temperature value and the preset temperature value is greater than the set difference, the first controller controls the heating plate 130 to stop operating.

[0052] Understandably, if the actual temperature value detected by the temperature sensor inside the first housing 110 is lower than the set temperature value, and the difference between the actual and set temperatures is greater than the set difference, it indicates that the internal temperature of the first housing 110 is too low and needs to be heated as soon as possible to prevent gallium from solidifying. The first controller controls the heating plate 130 to operate at full power to improve heating efficiency and ensure that the internal temperature of the first housing 110 reaches the set temperature as quickly as possible. When the difference between the actual and set temperatures is less than or equal to the set difference, the first controller can use a PID control algorithm for control. The integral term eliminates steady-state error, and the derivative term predicts the temperature change trend, thereby improving temperature regulation accuracy and reducing temperature fluctuations. This keeps the fluctuations within ±0.5℃, suitable for temperature control near the gallium liquidus line, and avoids frequent start-stop of the heating plate 130, which could cause the gallium oxide film to crack. Dynamic power output adjustment is achieved to avoid energy waste caused by continuous full-power heating of the heating plate 130, extend the service life of the heating plate 130, and has strong adaptability, adapting to different ambient temperatures through PID control algorithm parameter tuning. If the actual temperature value is greater than the set temperature value, and the difference between the actual temperature value and the preset temperature value is greater than the set difference, it indicates that the internal temperature of the first housing 110 is too high. The first controller controls the heating plate 130 to stop operating in order to reduce the internal temperature of the first housing 110.

[0053] For example, a cooling unit may be provided between the first housing 110 and the second housing 120. When the actual temperature value is greater than the set temperature value, and the difference between the actual temperature value and the preset temperature value is greater than the set difference, the first controller may control the cooling unit to start cooling the interior of the first housing 110 to improve temperature regulation efficiency. The cooling unit may be cooled by air cooling or liquid cooling.

[0054] For example, the preset temperature difference can be set to 2°C. When the actual temperature is lower than the preset temperature and the temperature difference is greater than 2°C, the first controller controls the heating plate 130 to heat at full power. When the temperature difference between the actual temperature and the preset temperature is within ±2°C, the first controller uses a PID control algorithm to control the temperature adjustment of the heating plate 130. When the actual temperature is higher than the preset temperature and the temperature difference is greater than 2°C, the first controller controls the heating plate 130 to stop heating and controls the cooling unit to start.

[0055] For example, the storage tank 100 is also provided with a communication module to send the internal temperature value of the first housing 110 detected by the temperature sensor to a data storage device for storage. Furthermore, the user can remotely adjust the set temperature value and the parameters of the PID control algorithm.

[0056] In some examples, as shown in FIG1, the storage tank 100 further includes: a display panel 150 disposed on the first housing 110 for displaying the actual temperature; and a signal indicator light disposed on the display panel 150 for displaying the working status of the heating plate 130.

[0057] Understandably, the first housing 110 may be equipped with a display panel 150 to display the actual temperature value, making it convenient for operators to observe the temperature situation. The display panel 150 may also be equipped with indicator lights to display the working status of the heating plate 130, making it convenient for operators to understand whether the heating plate 130 is operating normally.

[0058] For example, when the heating plate 130 is in normal condition, the green light of the signal indicator is constantly on; when the heating plate 130 is in heating mode, the red light of the signal indicator flashes; when the communication module is in normal communication mode, the blue light of the signal indicator is constantly on. An emergency stop button may also be provided on the first housing 110. If the signal indicator shows an abnormality, the operator can press the emergency stop button to cut off the power and promptly investigate the abnormality.

[0059] In some examples, as shown in FIG1, the storage tank 100 further includes a weighing unit 160 disposed at the bottom of the first housing 110 and located between the first housing 110 and the second housing 120, for weighing the liquid gallium metal stored in the first housing 110; wherein the display panel 150 is used to display the weighing value of the weighing unit 160.

[0060] It is understood that the storage tank 100 may also be equipped with a weighing unit 160. Specifically, the weighing unit 160 is located at the bottom of the first housing 110 and between the first housing 110 and the second housing 120. The weighing unit 160 can weigh the liquid gallium metal stored in the first housing 110, and can send the weight data of the liquid gallium metal to the display panel 150 to display the weighing value, so that the operator can understand the weight of the tank.

[0061] Understandably, the weighing unit 160 can be equipped with a load cell and a protective housing. The load cell has a weighing range of 2 tons, an accuracy of ±0.01%FS, and a temperature compensation range of -10℃ to +80℃. The protective housing covers the load cell to prevent liquid gallium from penetrating and corroding it, thus improving reliability. The protective housing can be made of stainless steel, with a yield strength of 1100MPa and a coefficient of thermal expansion of 10.8×10⁻⁶. -6 / ℃. This allows the stainless steel casing to resist the static pressure deformation of liquid gallium, ensuring long-term stability.

[0062] For example, the load cell can send the weighing data to the communication module, and the weighing data can be sent to the data storage device for storage.

[0063] For example, the weighing unit 160 can be calibrated before weighing. Specifically, after ensuring that there is no residual gallium metal in the first housing 110, the empty first housing 110 is zero-point calibrated, showing 0.0±0.1kg, which is acceptable; then, a weight calibration is performed, with a 500kg standard calibration weight placed in the first housing 110, showing 500±0.5kg, which is acceptable; then, a dynamic test is performed, by injecting water into the first housing 110 to simulate the release of liquid gallium metal and weighing it, with an error of less than 0.3kg, which is acceptable, thereby ensuring the accuracy of the weighing data.

[0064] In some examples, the storage tank 100 further includes a second controller that, when releasing the liquid gallium metal into the acid boiling tank, controls the opening and closing state of the valve body 140 based on the weighing value and a preset weight value; wherein, when the weighing value is less than or equal to the preset weight value, the second controller controls the valve body 140 to close.

[0065] It is understood that the storage tank 100 may also be equipped with a second controller. Both the weighing sensor and the valve body 140 are electrically connected to the second controller. Specifically, upon receiving a dispensing command, the second controller controls the valve body 140 to open and automatically dispense liquid gallium metal. The weighing sensor continuously monitors the weight of the liquid gallium metal within the first housing 110. As the operation of dispensing liquid gallium metal into the acid boiling tank proceeds, the weight of the liquid gallium metal within the first housing 110 decreases. When the weighing value is less than or equal to a preset weight value, it indicates that the set dispensing amount of liquid gallium metal into the acid boiling tank has been reached. The second controller then controls the valve body 140 to close, stopping the dispensing of liquid gallium metal into the acid boiling tank. This achieves automatic dispensing of liquid gallium metal with high precision.

[0066] In some examples, as shown in Figures 1 to 3, the storage tank 100 further includes: a cover 170 connected to the second housing 120 via a connecting portion 180; and a drive portion 190 disposed in the second housing 120, which drives the cover 170 to open or close the internal space of the second housing 120.

[0067] It is understood that the storage tank 100 may also be provided with a cover 170 and a drive unit 190. Specifically, the cover 170 is connected to the second housing 120 via a connecting part 180, so as to cover the internal space of the second housing 120 and the first housing 110, ensuring stable transportation. The drive unit 190 is located at the second housing 120, and can drive the cover 170 to open or close the internal space of the second housing 120, thereby realizing the automatic opening and closing of the cover 170.

[0068] Understandably, an infrared sensor can be installed at the edge of the cover 170 to detect whether someone is approaching the cover 170. If someone places their hand on the edge of the cover 170, the infrared sensor will immediately stop the drive unit 190 when it detects the obstacle, thus pausing the rotation of the cover 170 and ensuring safe use.

[0069] For example, a magnetic element can be embedded in the free end edge of the cover 170, and an iron sheet is provided at the corresponding position of the opening of the second housing 120. The magnetic element can be magnetically attracted to the iron sheet, and a sound amplifier is provided near the iron sheet. After the magnetic element and the iron sheet are magnetically attracted, a crisp metallic clanging sound is generated. After being amplified by the sound amplifier, it is easy for the staff to confirm that the cover 170 seals the second housing 120, ensuring the airtightness and thus ensuring the quality of the liquid gallium metal stored in the first housing 110. A piezoelectric ceramic sheet can also be provided at the opening of the second housing 120. After the magnetic element and the iron sheet are magnetically attracted, the circuit is triggered, the ceramic sheet vibrates, and the sound is amplified into a "beep" sound. The second housing 120 can also be provided with a volume adjustment knob to adjust the volume emitted by the sound amplifier.

[0070] In some examples, as shown in FIG3, the connection portion 180 includes a damping hinge, and the cover 170 is hinged to the second housing 120 via the damping hinge.

[0071] Understandably, the connecting part 180 may be a damping hinge, and the cover 170 may be hinged to the second housing 120 via the damping hinge. The damping hinge uses hydraulic cushioning to reduce impact force and prevent excessive speed when closing the cover 170, thus avoiding injury to the operator and improving protection.

[0072] In some examples, as shown in FIG3, the drive unit 190 includes: a drive motor disposed within the second housing 120; a transmission mechanism 191, the input end of which is connected to the power output shaft of the drive motor; and a push rod 192 connected to the output end of the transmission mechanism 191 for extending or retracting the second housing 120, the push rod 192 for pushing the cover 170 to rotate.

[0073] Understandably, the drive unit 190 may be equipped with a drive motor, a transmission mechanism 191, and a push rod 192. Specifically, the drive motor and transmission mechanism 191 are located inside the second housing 120. The power generated by the drive motor is transmitted to the push rod 192 through the transmission mechanism 191, enabling the push rod 192 to push the cover 170 to rotate relative to the second housing 120. The input end of the transmission mechanism 191 is connected to the power output shaft of the drive motor, and the output end of the transmission mechanism is connected to the push rod 192, thereby achieving automatic opening and closing of the cover 170. Furthermore, the rotation angle of the cover 170 can be adjusted by controlling the lifting distance of the push rod 192, preventing the cover 170 from closing due to its own weight and ensuring operational safety.

[0074] It is understandable that there may be two drive units 190, symmetrically arranged on both sides of the second housing 120, to ensure that a uniform pushing force is applied to the cover 170 and to ensure that the pushing is stable and reliable.

[0075] For example, the transmission mechanism 191 can be a linkage transmission mechanism 191, a lead screw transmission mechanism 191, or a gear transmission mechanism 191. As shown in Figure 3, the gear transmission mechanism 191 includes a first transmission gear 1911, a second transmission gear 1912, a first shaft 1913, a second shaft 1914, and a connecting member 1915. The first transmission gear 1911 meshes with the second transmission gear 1912. The first shaft 1913 is connected to the first transmission gear 1911 and biased towards it. The first shaft 1913 is connected to the power output shaft of a drive motor, so that the power generated by the drive motor drives the first shaft 1913 to rotate, thereby causing the first transmission gear 1911 to rotate and simultaneously generate a lifting displacement. The second transmission gear 1912 rotates synchronously with the first transmission gear 1911 and simultaneously moves up and down under the pushing force of the first transmission gear 1911. The second shaft 1914 is connected to the second transmission gear 1912, and the second shaft 1914 is biased towards the second transmission gear 1912. The push rod 192 is connected to the second shaft 1914 through the connector 1915, thereby enabling the push rod 192 to move up and down synchronously with the first transmission gear 1911 and the second transmission gear 1912.

[0076] For example, the storage tank 100 may also be equipped with an angle sensor and a third controller to detect the rotation angle of the cover 170. The angle sensor and the drive unit 190 are both electrically connected to the third controller. With this configuration, the third controller can control the operating state of the drive unit 190 according to the rotation angle of the cover 170 input by the user, so as to ensure that the cover 170 can accurately stop at the set angle and ensure safety.

[0077] In some examples, the first housing 110 described above comprises a perfluoroalkoxy resin housing; and / or the second housing 120 described above comprises a stainless steel housing.

[0078] Understandably, the first housing 110 can be made of perfluoroalkoxy resin. Perfluoroalkoxy resin is chemically inert and has excellent corrosion resistance to acids, alkalis, solvents, and most liquid metals, preventing reaction with metallic gallium, ensuring the purity of metallic gallium, and also has good thermal insulation properties. After temperature regulation by the temperature control unit, it can effectively reduce temperature loss. The second housing 120 can be made of stainless steel, and the perfluoroalkoxy resin housing can be welded to the stainless steel housing. For example, the stainless steel material can be 316L stainless steel, which has high hardness, moisture resistance, salt spray resistance, corrosion resistance, and high applicability, providing good protection and facilitating transportation.
