Detailed implementation manners

[0044] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

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

[0046] It can be understood that the storage tank 100 provided in the embodiments of the present disclosure is provided with a first housing 110, a second housing 120, a temperature adjustment unit, and a valve body 140. Among them, the first housing 110 stores liquid metal gallium, and the second housing 120 is sleeved on the first housing 110 to protect the first housing 110 through the second housing 120, thereby protecting the liquid metal gallium and facilitating transportation. The temperature adjustment unit is arranged between the first housing 110 and the second housing 120, and the temperature inside the first housing 110 is adjusted through the temperature adjustment unit, so as to ensure that the temperature inside the first housing 110 can keep the metal gallium in a liquid state. 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 position, the liquid metal gallium can be released into the acid cooking tank by opening the valve body 140. With such a setting, through the temperature adjustment of the temperature adjustment unit for the inside of the first housing 110, it is ensured that during the storage and transportation of the storage tank 100, the metal gallium always remains in a liquid state, so as to facilitate the direct release of the liquid metal gallium into the acid cooking tank, without the need to set up an additional heating process, and without the need for manual tools to transport the metal gallium in the storage tank 100 to the acid cooking tank, improving work efficiency and reducing labor intensity to meet the subsequent production requirements.

[0047] It can be understood that, as Figure 1 shown in the direction, the valve body 140 can be located at a position slightly above the bottom of the storage tank 100, so as to facilitate the outflow of the liquid metal gallium from the valve body 140 by its own weight and ensure smooth outflow. The second housing 120 can be selected as a metal housing to have a higher strength and improve the protection. The first housing 110 can be made of a material that does not react with the metal gallium to ensure the quality of the metal gallium. The temperature inside the first housing 110 can be adjusted to 40°C to 50°C through the temperature adjustment unit to ensure that the metal gallium remains in a liquid state.

[0048] In some examples, as Figure 1 shown, the above-mentioned temperature adjustment unit includes: a heating plate 130 arranged 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] It can be understood that the temperature adjustment part can be provided with a heating plate 130, a temperature sensor and a first controller. Specifically, the heating plate 130 can be arranged at the bottom of the first housing 110 and in surface contact with 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. The temperature sensor sends the detected actual temperature value to the first controller, and 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 adjust the temperature inside the first housing 110 to ensure that the gallium metal remains in a liquid state and has good fluidity.

[0050] Exemplarily, the heating plate 130 can be a silicone heating plate 130. The silicone heating plate 130 can generate heat in a planar manner, and the power density is 0.5 W / cm 2 to 2 W / cm 2 , and the 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 of gallium metal or rupture of the oxide film. The temperature sensor can be a PT100 platinum electric temperature vibration sensor. The PT100 platinum electric temperature vibration sensor has the characteristics of corrosion resistance, high precision, anti-vibration and durability. At the same time, compared with traditional sensors, the resistance-temperature relationship of the platinum resistance of the PT100 platinum electric temperature vibration sensor is highly linear, which is convenient for the first controller to accurately and quickly calculate the output power of the heating plate 130 and ensure the temperature adjustment effect of the heating plate 130.

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

[0052] It can be understood that when the actual temperature value inside the first housing 110 detected by the temperature sensor is less than the set temperature value, and the difference between the preset temperature value and the actual temperature value is greater than the set difference, it indicates that the temperature inside the first housing 110 is too low and needs to be heated as soon as possible to prevent the solidification of gallium metal. The first controller controls the heating plate 130 to operate at full power to improve the heating efficiency and ensure that the temperature inside the first housing 110 reaches the preset temperature as soon as possible. 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 can use the PID control algorithm for control. By means of the integral term, the steady-state error is eliminated, and the differential term predicts the temperature change trend, thereby improving the temperature regulation accuracy and reducing the temperature fluctuation, so that the fluctuation is controlled within ±0.5 °C to suit the temperature control near the liquidus of gallium metal and avoid the rupture of the gallium metal oxide film caused by the frequent start and stop of the heating plate 130. The dynamic adjustment of the power output is realized, which avoids the waste of energy caused by the continuous full-power heating of the heating plate 130, prolongs the service life of the heating plate 130, and has strong adaptability. The PID control algorithm parameters are tuned to adapt to different ambient temperatures. 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, it indicates that the temperature inside the first housing 110 is too high, and the first controller controls the heating plate 130 to stop operating to reduce the temperature inside the first housing 110.

[0053] Exemplarily, a cooling part may also 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 can control the cooling part to start to cool the inside of the first housing 110 to improve the temperature regulation efficiency. The cooling part can be selected to use air cooling or liquid cooling for cooling.

[0054] Exemplarily, the set difference can be set to 2 °C. When the actual temperature value is less than the preset temperature value 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 value and the preset temperature value is within ±2 °C, the first controller uses the PID control algorithm to control the temperature adjustment of the heating plate 130. When the actual temperature value is greater than the preset temperature value and the temperature difference is greater than 2 °C, the first controller controls the heating plate 130 to stop heating and controls the cooling part to start.

[0055] Exemplarily, the storage tank 100 is also provided with a communication module to send the temperature value inside the first housing 110 detected by the temperature sensor to the data memory for storage. And the user can remotely adjust the set temperature value and the PID control algorithm parameters.

[0056] In some examples, such as Figure 1As shown, the above storage tank 100 further includes: a display panel 150, disposed on the first housing 110, for displaying the actual temperature; a signal indicator light, disposed on the display panel 150, for displaying the working state of the heating plate 130.

[0057] It can be understood that the first housing 110 can be provided with a display panel 150 to display the actual temperature value, facilitating the operator to observe the temperature situation. The display panel 150 can also be provided with a signal indicator light to display the working state of the heating plate 130, facilitating the operator to understand whether the heating plate 130 is operating normally.

[0058] Exemplarily, when the heating plate 130 is in a normal state, the green light of the signal indicator light is always on; when the heating plate 130 is in a heating state, the red light of the signal indicator light flashes; when the communication module is in a normal communication state, the blue light of the signal indicator light is always on. An emergency stop button can also be provided on the first housing 110. When the signal indicator light shows an abnormal situation, the operator can press the emergency stop button to cut off the power supply in time to troubleshoot the abnormal situation.

[0059] In some examples, as Figure 1 shown, the above storage tank 100 further includes: a weighing unit 160, disposed at the bottom of the first housing 110, between the first housing 110 and the second housing 120, for weighing the liquid metal gallium 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 can be understood that the storage tank 100 can also be provided with a weighing unit 160. Specifically, the weighing unit 160 is disposed at the bottom of the first housing 110 and between the first housing 110 and the second housing 120. The liquid metal gallium stored in the first housing 110 can be weighed by the weighing unit 160, and the weighing unit 160 can send the weight data of the liquid metal gallium to the display panel 150 to display the weighing value through the display panel 150, facilitating the operator to understand the canned weight.

[0061] It can be understood that the weighing unit 160 can be provided with a weighing sensor and a protective housing. Among them, the measuring range of the weighing sensor can be 2 tons, the accuracy is ±0.01% FS, and the temperature compensation range is -10°C to +80°C. The protective housing covers the weighing sensor to prevent the liquid metal gallium from permeating and corroding the weighing sensor through the protective housing, improving the reliability. The protective housing can be made of a stainless steel housing, and the yield strength of the stainless steel housing is 1100 MPa, and the thermal expansion coefficient is 10.8×10 -6 / °C. So that the stainless steel housing can resist the static pressure deformation of the liquid metal gallium and ensure long-term stability.

[0062] Exemplarily, the load cell can send the weighing data to the communication module, and the weighing data has been sent to the data memory for storage.

[0063] Exemplarily, the weighing unit 160 can be calibrated before weighing with the weighing unit 160. Specifically, with no residual gallium metal in the first housing 110, zero calibration is performed on the empty first housing 110, and a display of 0.0 ± 0.1 kg is qualified; subsequently, calibration with weights is performed. A 500 kg standard calibration weight is placed in the first housing 110, and a display of 500 ± 0.5 kg is qualified; subsequently, a dynamic test is performed. Water is injected into the first housing 110 to simulate the dropping of liquid gallium metal and weighing is carried out, and an error less than 0.3 kg is qualified, thereby ensuring the accuracy of the weighing data.

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

[0065] It can be understood that the storage tank 100 can also be provided with a second controller. The load cell and the valve body 140 are both electrically connected to the second controller. Specifically, after receiving a dropping instruction, the second controller controls the valve body 140 to open to automatically drop the liquid gallium metal. The load cell detects the weight of the liquid gallium metal in the first housing 110 in real time. As the operation of releasing the liquid gallium metal to the acid cooking tank proceeds, the weight of the liquid gallium metal in the first housing 110 decreases. When the weighing value is less than or equal to the preset weight value, it indicates that the set release amount of the liquid gallium metal released to the acid cooking tank has been reached, and the second controller controls the valve body 140 to close, stopping the release of the liquid gallium metal to the acid cooking tank. Thus, automatic dropping of the liquid gallium metal is achieved with high dropping accuracy.

[0066] In some examples, as Figures 1 to 3 shown, the above storage tank 100 further includes: a cover body 170, which is connected to the above second housing 120 through a connecting portion 180; a driving portion 190, which is arranged on the above second housing 120, and drives the cover body 170 to open or close the internal space of the above second housing 120 through the above driving portion 190.

[0067] It can be understood that the storage tank 100 may also be provided with a cover body 170 and a driving part 190. Specifically, the cover body 170 is connected to the second housing 120 through a connecting part 180 to seal the internal spaces of the second housing 120 and the first housing 110 through the cover body 170, ensuring stable transportation. The driving part 190 is arranged at the second housing 120, and the internal space of the second housing 120 can be driven by the driving part 190 to open or close the cover body 170, so as to realize the automatic opening and closing of the cover body 170.

[0068] It can be understood that an infrared sensor can be installed at the edge of the cover body 170 to detect whether someone approaches the cover body 170. When a person places their hand at the edge of the cover body 170, the infrared sensor will immediately stop the operation of the driving part 190 when it detects an obstacle to pause the rotation of the cover body 170, ensuring safe use.

[0069] Exemplarily, a magnetic part can be embedded at the free end edge of the cover body 170, an iron sheet is arranged at the corresponding position of the opening of the second housing 120, the magnetic part can be magnetically attracted to the iron sheet, and a sound amplifier is arranged near the iron sheet. After the magnetic part and the iron sheet are magnetically attracted, a clear metallic impact sound will be generated, which is amplified by the sound amplifier to facilitate the staff to confirm that the cover body 170 seals the second housing 120, ensuring the sealing performance, and thus ensuring the quality of the liquid metal gallium stored in the first housing 110. A piezoelectric ceramic sheet can also be arranged at the opening of the second housing 120. After the magnetic part and the iron sheet are magnetically attracted, the circuit will be triggered, and the ceramic sheet will vibrate, which is amplified by the sound amplifier into a "beep" prompt 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 Figure 3 shown, the above-mentioned connecting part 180 includes a damping hinge, and the above-mentioned cover body 170 is hinged to the above-mentioned second housing 120 through the above-mentioned damping hinge.

[0071] It can be understood that the connecting part 180 can select a damping hinge, and the cover body 170 can be hinged to the second housing 120 through the damping hinge. The damping hinge buffers through hydraulic pressure to reduce the impact force, avoid too fast speed when closing the cover body 170, cause harm to the operator, and improve the protection performance.

[0072] In some examples, as Figure 3 shown, the above-mentioned driving part 190 includes: a driving motor arranged in the above-mentioned second housing 120; a transmission mechanism 191, the input end of the above-mentioned transmission mechanism 191 is connected to the power output shaft of the above-mentioned driving motor; a push rod 192, connected to the output end of the above-mentioned transmission mechanism 191, used to extend or retract the above-mentioned second housing 120, and the above-mentioned push rod 192 is used to push the above-mentioned cover body 170 to rotate.

[0073] It can be understood that the driving part 190 can be provided with a driving motor, a transmission mechanism 191 and a push rod 192. Specifically, the driving motor and the transmission mechanism 191 are arranged in the second housing 120, and the power generated by the driving motor is transmitted to the push rod 192 through the transmission mechanism 191, so that the push rod 192 can push the top cover body 170 to rotate relative to the second housing 120. Among them, the input end of the transmission mechanism 191 is connected to the power output shaft of the driving motor, and the output end of the transmission mechanism is connected to the push rod 192, so as to realize the automatic opening and closing of the cover body 170, and the rotation angle of the cover body 170 can be adjusted by controlling the lifting distance of the push rod 192, avoiding the cover body 170 from closing due to its own weight and ensuring operation safety.

[0074] It can be understood that two driving parts 190 can be provided, which are symmetrically arranged on both sides of the second housing 120 to ensure uniform top thrust on the cover body 170 and ensure stable and reliable top pushing.

[0075] Exemplarily, the transmission mechanism 191 can be selected from a link transmission mechanism 191, a lead screw transmission mechanism 191 and a gear transmission mechanism 191. Among them, as Figure 3 shown in the figure is the gear transmission mechanism 191, which includes a first transmission gear 1911, a second transmission gear 1912, a first shaft body 1913, a second shaft body 1914 and a connecting piece 1915. Among them, the first transmission gear 1911 meshes with the second transmission gear 1912, the first shaft body 1913 is connected to the first transmission gear 1911, and the first shaft body 1913 is offset from the first transmission gear 1911. The first shaft body 1913 is connected to the power output shaft of the driving motor, so that the power generated by the driving motor drives the first shaft body 1913 to rotate, and while driving the first transmission gear 1911 to rotate, a lifting displacement is generated. The second transmission gear 1912 and the first transmission gear 1911 rotate synchronously and lift synchronously under the top push of the first transmission gear 1911. The second shaft body 1914 is connected to the second transmission gear 1912, and the second shaft body 1914 is offset from the second transmission gear 1912. The push rod 192 is connected to the second shaft body 1914 through the connecting piece 1915, so that the push rod 192 can lift synchronously with the first transmission gear 1911 and the second transmission gear 1912.

[0076] Exemplarily, the storage tank 100 can also be provided with an angle sensor and a third controller to detect the rotation angle of the cover body 170. Both the angle sensor and the driving part 190 are electrically connected to the third controller. With such a setting, the third controller can control the operating state of the driving part 190 according to the rotation angle of the cover body 170 input by the user, so as to ensure that the cover body 170 can accurately stop at the set angle and ensure safety.

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

[0078] It can be understood that the first housing 110 can be selected as a perfluoroalkoxy resin housing. The perfluoroalkoxy resin has strong chemical inertness, excellent corrosion resistance to acids, alkalis, solvents and most liquid metals, can avoid reacting with gallium metal, ensure the purity of gallium metal, and has good heat preservation performance. After the temperature is adjusted by the temperature adjustment part, the temperature loss can be effectively reduced. The second housing 120 can be selected as a stainless steel housing, and the perfluoroalkoxy resin housing can be welded to the stainless steel housing. Exemplarily, the stainless steel material can be selected as 316L stainless steel, which has high hardness, moisture-proof, salt spray-proof, corrosion-resistant and high applicability, has good protection, and is convenient for transportation.

[0079] It should be understood that the terms first, second, etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance. Although the terms first, second, etc. can be used in this article to describe various units, these units should not be limited by these terms. These terms are only used to distinguish one unit from another. For example, the first unit can be called the second unit, and similarly, the second unit can be called the first unit, without departing from the scope of the exemplary embodiments of the present invention.

[0080] It should be understood that the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, B exists alone, and A and B exist simultaneously.
