Description

TECHNICAL FIELD

[0001] The present application relates to the technical field, and in particular to a low-melting-point substance storage device. BACKGROUND

[0002] Low-melting-point metals and alloys thereof are widely used in the industries of semiconductor, compound semiconductor, low-temperature welding, etc. The low-melting-point metals and alloys thereof are usually in liquid state or solid state at room temperature. During transportation, if the low-melting-point metals and alloys thereof are in liquid state, the surface of the liquid substance has a certain flowability, which makes the part of the liquid surface in contact with air larger, resulting in an increase in the area of the low-melting-point metals and alloys thereof oxidized and an increase in the possibility of being oxidized. In addition, the metals and alloys thereof in liquid state are not convenient for transportation, so the low-melting-point metals and alloys thereof are usually transported in solid state. At the same time, the low-melting-point metals and alloys thereof usually have strong corrosiveness and toxicity, so necessary protection devices must be provided for the transportation of the low-melting-point metals and alloys thereof.

[0003] At present, the low-melting-point metals and alloys thereof are usually transported by using a refrigerated vehicle for food transportation. The refrigeration temperature of the refrigerated vehicle is relatively low, generally at -10℃ to -20℃. However, the logistics service cost of directly using the refrigerated vehicle to transport the low-melting-point metals and alloys thereof is high, which will cause a large cost burden. In the prior art, there is also a transportation cabinet specially used for transporting the low-melting-point metals and alloys thereof. The transportation cabinet is provided with a heat preservation layer, and a plurality of ice boxes and containers are placed in the transportation cabinet. The low-melting-point metals and alloys thereof and the ice boxes are placed in the containers, so as to further ensure that the low-melting-point metals and alloys thereof have a relatively low temperature during transportation, so that the low-melting-point metals and alloys thereof are transported in solid state. However, the volume of the transportation cabinet is relatively large, so the transportation is difficult. In addition, the containers contain both the low-melting-point metals and alloys thereof (which are placed in leak-proof bags) and the ice boxes. Since the low-melting-point metals and alloys thereof are in solid state, the shaking and bumping during transportation may cause the leak-proof bags to be damaged. The ice boxes are easy to condense water vapor in the air, and some low-melting-point metals and alloys thereof (such as metal gallium or gallium indium tin alloy) will react when contacting water, which is easy to cause pollution of the low-melting-point metals and alloys thereof.

[0004] Therefore, it is necessary to improve the transportation cabinet for transporting the low-melting-point metals and alloys thereof in the prior art to solve the above problems.

[0005] It should be noted that the introduction to the background art above is merely to facilitate the clear, complete explanation of the technical solutions of the present application, and to facilitate the understanding of those skilled in the art.

[0030] The present application will be described in detail below with reference to the embodiments shown in the drawings, but it should be noted that these embodiments are not limiting to the present application, and equivalent transformations or substitutions of function, method, or structure made by those skilled in the art based on these embodiments are within the scope of the present application.

[0032] Please refer to Figure 1 and Figure 2 The present application provides a specific embodiment of a low-melting-point substance storage device 10. The low-melting-point substance storage device 10 is used to store a substance to be stored and keep the substance to be stored (not shown) in a solid state, and the current ambient temperature of the low-melting-point substance storage device 10 is higher than the melting point of the substance to be stored.

[0033] By storing the substance to be stored inside the low-melting-point substance storage device 10, the current ambient temperature inside the low-melting-point substance storage device 10 is lower than the melting point of the substance to be stored, thereby keeping the substance to be stored in a solid state inside the low-melting-point substance storage device 10, and facilitating the transportation of the substance to be stored with a melting point lower than the current ambient temperature.

[0034] Please refer to Figure 1 shown, Figure 1 A structure diagram of the low-melting-point substance storage device 10 shown in the present application is shown, which includes a bottle body 11, a cover body 12 arranged on the top of the bottle body 11, a sealing member 40, and a pumping mechanism 13 penetrating through the cover body 12.

[0035] The bottle body 11 comprises an inner bottle body 111, an inner heat insulation layer 112, an aerogel heat insulation layer 113 and a protective layer 114 formed in sequence from inside to outside on the outer side of the inner bottle body 111. The bottle body 11 and the cover body 12 are detachably assembled, and the inner bottle body 111 and the cover body 12 movably enclose a protective cavity 20 for containing the substance to be stored and keeping the substance to be stored in a solid state, and the bottle body 11 and the cover body 12 form a matching surface 30, and the sealing member 40 is arranged on the matching surface 30. The charging and discharging mechanism 13 is used for filling the protective cavity 20 with inert protective gas or vacuumizing the protective cavity 20.

[0036] In actual application, since the current environment temperature of the low-melting-point substance storage device 10 is higher than the melting point of the substance to be stored, the substance to be stored is usually stored in a cold storage. Before the substance to be stored is transported to a destination, the cover body 12 and the bottle body 11 are separated, the substance to be stored is taken out from the cold storage and quickly placed in the protective cavity 20, and the cover body 12 and the bottle body 11 are sealed; after the substance to be stored is transported to the destination, the cover body 12 and the bottle body 11 are separated, the substance to be stored is taken out from the protective cavity 20 and quickly placed in a designated storage position, and the cover body 12 and the bottle body 11 are sealed. During the process of placing the substance to be stored in the protective cavity 20, attention should be paid to the contact between the substance to be stored and the inner bottle body 111. Although the substance to be stored (for example, a low-melting-point metal material) has lower hardness than ordinary metal materials, it is still necessary to prevent the protrusions or sharp ends of the low-melting-point metal material from damaging the inner bottle body 111.

[0037] It should be noted that although the current environment temperature of the low-melting-point substance storage device 10 is higher than the melting point of the substance to be stored, since the temperature of the substance to be stored taken out from the cold storage is relatively low, the substance to be stored will not have a large heat exchange in a short time after being taken out from the cold storage, that is, the substance to be stored will not immediately change from a solid state to a liquid state. Therefore, it is necessary to quickly place the substance to be stored in the protective cavity 20, and after being placed in the protective cavity 20, the cover body 12 and the bottle body 11 also need to be quickly sealed, so as to reduce the heat exchange and the exposure time of the substance to be stored in the current environment of the low-melting-point substance storage device 10. Similarly, when the substance to be stored is taken out from the protective cavity 20, the substance to be stored also needs to be quickly placed in a designated storage position.

[0038] More specifically, the protective chamber 20 is vacuumized by the pumping mechanism 13, for example, to below 100 Pa; after the low-melting substance storage device 10 is transported to the destination, the pumping mechanism 13 fills the protective chamber 20 with inert protective gas, so that the air pressure in the protective chamber 20 is consistent with the current ambient air pressure, to separate the cover 12 and the bottle 11; and the substance to be stored is taken out of the protective chamber 20. Alternatively, the pumping mechanism 13 fills the protective chamber 20 with inert protective gas, so that the air pressure in the protective chamber 20 is higher than the current ambient air pressure, for example, maintained at 2-3 atmospheres; after the low-melting substance storage device 10 is transported to the destination, the pumping mechanism 13 makes the air pressure in the protective chamber 20 consistent with the current ambient air pressure, to separate the cover 12 and the bottle 11; and the substance to be stored is taken out of the protective chamber 20. The current ambient air pressure is the current air pressure of the environment where the low-melting substance storage device 10 is located.

[0039] In the present application, first, the bottle 11 and the cover 12 are detachably assembled, thereby achieving separation or sealing of the bottle 11 and the cover 12, and achieving the purpose of opening or sealing the protective chamber 20 formed inside the bottle 11; and the bottle 11 and the cover 12 form a matching surface 30, and the sealing member 40 is arranged on the matching surface 30, so as to better seal the protective chamber 20 formed inside the bottle 11. Second, the four-layer structure (i.e., the inner bottle 111, the inner thermal insulation layer 112, the aerogel thermal insulation layer 113, and the protective layer 114) plays a role in isolating the internal environment temperature of the bottle 11 (i.e., the current environment temperature of the protective chamber 20) and the external environment temperature (i.e., the current environment temperature of the low-melting substance storage device 10), and the double-layer thermal insulation (i.e., the inner thermal insulation layer 112 and the aerogel thermal insulation layer 113) plays a role in keeping the substance to be stored warm, better preventing heat exchange, so that the substance to be stored remains in solid state in the protective chamber 20 and does not melt into liquid state, thereby facilitating transportation of the substance to be stored with a lower melting point (i.e., the environment temperature of the low-melting substance storage device 10 is higher than the melting point of the substance to be stored). Finally, since some special substances to be stored need to be transported in special environments, for example, need to be transported in inert protective gas or in vacuum, the pumping mechanism 13 can fill the protective chamber 20 with inert protective gas or vacuumize the protective chamber 20, thereby achieving the purpose of transporting the substance to be stored in inert protective gas or in vacuum, and further playing a role in protecting the substance to be stored during transportation, so as to prevent the substance to be stored from being oxidized by oxygen or contaminated by water vapor during transportation. The inert protective gas can be, for example, argon (Ar), nitrogen (N2), and hydrogen mixed gas, which are not limited in the present embodiment.

[0040] In one embodiment, the pumping mechanism 13 is arranged on the cover 12, and the protective chamber 20 is arranged in the bottle 11. Figure 1As shown, the bottle body 11 has a first thread, the cap body 12 has a second thread matched with the first thread, and the bottle body 11 and the cap body 12 are screwed together by the first thread and the second thread, so that the bottle body 11 and the cap body 12 are detachably assembled.

[0041] Further, the first thread is formed on the outside of the bottle body 11, and the second thread is formed on the inside of the cap body 12; or the first thread is formed on the inside of the bottle body 11, and the second thread is formed on the outside of the cap body 12.

[0042] In an embodiment, referring to Fig. 1, Figure 1 As shown, the pumping mechanism 13 comprises a communication pipe 131 penetrating the cap body 12 and a valve 132 arranged outside the communication pipe 131, the communication pipe 131 has a passage 130 formed therein and connected with the protection chamber 20, and the valve 132 is movable to close the passage 130.

[0043] When the protection chamber 20 is filled with inert protective gas, the passage 130 is opened by the valve 132, and the inert protective gas is delivered to the protection chamber 20 through the passage 130 formed by the communication pipe 131, and when the protection chamber 20 reaches the inert protective gas condition (i.e., the concentration of the inert protective gas in the protection chamber 20 reaches a preset range), the passage 130 is closed by the valve 132, so that the protection chamber 20 is filled with inert protective gas, and the substance to be stored in the protection chamber 20 is transported under the inert protective gas condition. Similarly, when the protection chamber 20 is kept in vacuum, the passage 130 is opened by the valve 132, and the protection chamber 20 is pumped to vacuum through the passage 130 formed by the communication pipe 131, and when the protection chamber 20 reaches the vacuum condition, the passage 130 is closed by the valve 132, so that the protection chamber 20 is kept in vacuum, and the substance to be stored in the protection chamber 20 is transported under the vacuum condition.

[0044] More specifically, in an embodiment, referring to Fig. 1, Figure 1 As shown, the communication pipe 131 at least comprises a gas filling pipe 1311 and a gas suction pipe 1312, and the valve 132 at least comprises a first valve 1321 and a second valve 1322, the first valve 1321 is movable to close the gas filling pipe 1311, and the second valve 1322 is movable to close the gas suction pipe 1312.

[0045] When the protection chamber 20 is filled with inert protective gas, the first valve 1321 is opened to open the gas inlet pipe 1311, the second valve 1322 is opened to open the gas outlet pipe 1312, the inert protective gas is delivered to the protection chamber 20 through the gas inlet pipe 1311, and the original gas in the protection chamber 20 is discharged through the gas outlet pipe 1312, until the protection chamber 20 reaches the inert protective gas condition (or the discharge amount of the original gas in the protection chamber 20 reaches the preset threshold), the gas outlet pipe 1312 is closed, and the inert protective gas continues to be delivered to the protection chamber 20 through the gas inlet pipe 1311, when the inert protective gas in the protection chamber 20 reaches 2-3 atmospheres, the gas inlet pipe 1311 is closed; after the low-melting-point substance storage device 10 is transported to the destination, the gas outlet pipe 1312 is opened, so that the air pressure in the protection chamber 20 is consistent with the current environment air pressure, the cover 12 and the bottle body 11 are separated, and the substance to be stored is taken out from the protection chamber 20. When the protection chamber 20 is kept in vacuum, the first valve 1321 is opened to open the gas inlet pipe 1311, and the protection chamber 20 is vacuumized through the gas inlet pipe 1311, when the protection chamber 20 reaches the vacuum condition, the gas inlet pipe 1311 is closed; after the low-melting-point substance storage device 10 is transported to the destination, the second valve 1322 is opened to open the gas outlet pipe 1312, and the inert protective gas is delivered to the protection chamber 20 through the gas outlet pipe 1312, so that the air pressure in the protection chamber 20 is consistent with the current environment air pressure, the cover 12 and the bottle body 11 are separated, and the substance to be stored is taken out from the protection chamber 20.

[0046] It should be noted that, since the reaction speed of the substance to be stored (for example, low-melting-point metal material) and oxygen or water vapor is relatively slow, it is not necessary to use ultra-high vacuum or ultra-high atmospheric pressure of inert protective gas to protect the low-melting-point metal material, which will not increase the cost, and will not have extremely high requirements on the sealing, hardness and supportability of the low-melting-point substance storage device 10. Therefore, the above-mentioned example of the protection chamber 20 reaching 2-3 atmospheres when storing the substance to be stored is exemplarily described.

[0047] In one embodiment, referring to FIG. 1, the low-melting-point substance storage device 10 includes a bottle body 11 and a cover 12, the bottle body 11 is provided with a protection chamber 20, the cover 12 is provided with a protection chamber 20, and the protection chamber 20 is provided with a low-melting-point substance 21. Figure 2 As shown in FIG. 1, the inner thermal insulation layer 112 includes a first thermal insulation layer 1121 and a second thermal insulation layer 1122 formed in sequence from inside to outside, the side of the inner bottle body 111 is formed on the inner surface of the first thermal insulation layer 1121, the aerogel thermal insulation layer 113 is in contact with the second thermal insulation layer 1122, a gap 1123 is formed between the first thermal insulation layer 1121 and the second thermal insulation layer 1122, and the gap 1123 is filled with inert protective gas or kept in vacuum.

[0048] Specifically, the first thermal insulation layer 1121 and the second thermal insulation layer 1122 are both metal layers, and the materials of the first thermal insulation layer 1121 and the second thermal insulation layer 1122 are both, for example, stainless steel.

[0049] The side of the inner bottle body 111 is formed on the inner surface of the first thermal insulation layer 1121. Since the first thermal insulation layer 1121 has a certain strength, it will not be deformed or damaged due to bumps during use, which will affect the size and thermal insulation effect of the protection chamber 20. The second thermal insulation layer 1122 and the aerogel thermal insulation layer 113 are in contact. The second thermal insulation layer 1122 supports the aerogel thermal insulation layer 113 and can further protect the inner thermal insulation layer 112, preventing the current environment where the low-melting-point substance storage device 10 is located from damaging the first thermal insulation layer 1121 and the gap 1123. The second thermal insulation layer 1122 also needs good strength and weather resistance. The gap 1123 is filled with inert protective gas or kept vacuum through a special process, which is not limited in the embodiment. The gap 1123 filled with inert protective gas or kept vacuum further reduces the medium of heat transfer, thereby effectively blocking the transfer of heat.

[0050] It should be noted that the device for storing the to-be-stored substance in the prior art is usually stored by a device made of plastic material, such as one of PVC, PE, PP, ABS, or nylon. Although such material has the advantages of corrosion resistance and low cost, the thermal insulation performance of plastic material is poor, and the hardness is also poor, which cannot directly form a sandwich structure similar to the inner thermal insulation layer 112 disclosed in the present application. The sandwich structure with double metal layers in the present application can solve the problem of large deformation caused by pressure difference if a sandwich structure made of plastic material is used in the prior art.

[0051] In an embodiment, the aerogel thermal insulation layer 113 is a silica aerogel layer or a polymer aerogel layer; and / or, the aerogel thermal insulation layer 113 contains titanium dioxide particles; and / or, the material of the inner bottle body 111 is an organic material; and / or, the thickness of the inner bottle body 111 is 0.05mm-1.5mm; and / or, the material of the protective layer 114 is rubber; and / or, the to-be-stored substance is a low-melting-point metal material, which includes a low-melting-point metal (such as gallium, rubidium, or cesium) and a low-melting-point alloy (such as a gallium-indium eutectic alloy, a gallium-tin alloy, a gallium-bismuth alloy, or a gallium-zinc alloy). For example, the thickness of the inner bottle body 111 is 0.05mm, 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, or 1.5mm.

[0052] Specifically, the material of the protective layer 114 is rubber, which can play a buffering role. Bumps may occur during transportation of the low-melting-point substance storage device 10, and rubber can alleviate the impact of bumps on the to-be-stored substance stored in the protection chamber 20.

[0053] The aerogel thermal insulation layer 113 is located on the inner side of the protective layer 114, and can be a silica aerogel layer or a polymer aerogel layer; the aerogel is a nano-porous material with extremely low thermal conductivity, because the nano-porous structure of the aerogel greatly limits the movement of air molecules, reduces heat conduction, and the pore size of the aerogel is smaller than the average free path of air molecules, which can inhibit convective heat transfer; preferably, the aerogel thermal insulation layer 113 contains titanium dioxide particles, which have a reflective effect and can reflect thermal radiation, further improving the thermal insulation and warmth retention effect.

[0054] Further, the aerogel thermal insulation layer 113 is formed into a porous material by a sol-gel method or mixed with an adhesive to form an aerogel composite material, and is formed by a sandwich filling process or a spraying process. Because the aerogel has extremely low thermal conductivity (about 0.013-0.016 W / m·K), as a thermal insulation material layer, and is located on the outer side of the inner thermal insulation layer 112, it can prevent the low-melting-point substance storage device 10 from exchanging heat with the current environment of the protective cavity 20. In addition, because the aerogel has low mechanical strength, it can also play a buffering role together with the protective layer 114.

[0055] The side portion of the inner bottle body 111 is attached to the inner surface of the first thermal insulation layer 1121, and the inner bottle body 111 includes a side portion and a bottom portion. The material of the inner bottle body 111 can be selected from organic materials such as PVC, PE, PP, ABS, etc., thereby preventing the problem of contamination of the to-be-stored substance caused by direct contact between the first thermal insulation layer 1121 and the to-be-stored substance. In particular, if the to-be-stored substance is a low-melting-point metal material, the low-melting-point metal material can mostly corrode various metals including stainless steel and form alloys with other metals. At the same time, the cost of the organic material is relatively low, which plays a role in reducing the cost, and various processes can be used to form the inner bottle body 111, such as fluidized spraying, powder electrostatic spraying, hot melting method, suspension coating, etc. to form the side portion of the inner bottle body 111 on the inner surface of the first thermal insulation layer 1121. Therefore, the inner bottle body 111 can prevent the first thermal insulation layer 1121 from contaminating the to-be-stored substance, and will not cause excessive increase in cost. The thickness of the inner bottle body 111 is 0.05mm-1.5mm, thereby neither affecting the capacity of the protective cavity 20, nor causing the problem of damage or scratching of the inner bottle body 111 when storing the to-be-stored substance due to the thinness of the inner bottle body 111. At the same time, the low-melting-point substance storage device 10 disclosed in the present application can be recycled after transporting the to-be-stored substance to the destination and taking out the to-be-stored substance, so as to be used again next time, that is, the low-melting-point substance storage device 10 can be reused and will not cause an increase in cost even after multiple uses.

[0056] It should be noted that the double-layer thermal insulation (i.e., the inner thermal insulation layer 112 and the aerogel thermal insulation layer 113) is adopted in the present application, the inner thermal insulation layer 112 is a double-layer hollow thermal insulation layer of metal, the aerogel thermal insulation layer 113 has a lower thermal conductivity, and the aerogel thermal insulation layer 113 contains titanium dioxide particles, thereby better preventing heat radiation, and the inner thermal insulation layer 112 also has a lower thermal conductivity, thereby further preventing heat exchange. The aerogel thermal insulation layer 113 located on the outer side has a low strength and can play a buffering role; the inner thermal insulation layer 112 located on the inner side has a high strength and can play a supporting role, thereby not being deformed and protecting the to-be-stored substance, and facilitating the attachment of the side of the inner bottle body 111 to the inner surface of the inner thermal insulation layer 112. If the aerogel thermal insulation layer 113 is close to the inner bottle body 111, the inner bottle body 111 is not easily attached to the inner surface of the aerogel thermal insulation layer 113, the pores of the aerogel are easily deformed under the extrusion of the metal, and the deformed pores are not easily restored, and the aerogel becomes dense and the pores are reduced under the extrusion of the metal, thereby reducing the thermal insulation effect of the aerogel; and in the present application, the aerogel thermal insulation layer 113 is arranged on the outer side, and the inner thermal insulation layer 112 supports the aerogel thermal insulation layer 113, thereby the aerogel thermal insulation layer 113 is occasionally subjected to external force, but after the external force is removed, the pores are restored, thereby not affecting the thermal insulation effect of the aerogel thermal insulation layer 113.

[0058] When the to-be-stored substance is stored in the low-melting-point substance storage device 10, the current environmental information in the protection chamber 20 is detected in real time by the detection device 116, and the current environmental information is displayed in real time by the display 117, thereby facilitating the operator to check the internal condition of the protection chamber 20 at any time, reducing the checking steps of the operator, and shortening the checking time of the operator. For example, the operator can judge whether the low-melting-point substance storage device 10 leaks or the heat exchange is large enough to melt the to-be-stored substance according to the current environmental information displayed by the display 117, without the need to separate the bottle body 11 and the cover 12, thereby shortening the checking time. In addition, the detection device 116 is arranged on the upper side of the inner bottle body 111, thereby not affecting the to-be-stored substance when the to-be-stored substance is stored in the protection chamber 20.

Among them, the buzzer is in working state when the temperature in the current environmental information exceeds the preset temperature threshold, and / or the buzzer is in working state when the pressure in the current environmental information exceeds the preset pressure threshold. Based on this, when the temperature and / or humidity in the current environmental information is abnormal (i.e. the temperature exceeds the preset temperature threshold or the humidity exceeds the preset pressure threshold), the buzzer is in working state (i.e. the buzzer alarms) to warn the operator.

[0060] In an embodiment, the display 117 is electrically connected with the detecting device 116 and the buzzer respectively, so that the current environmental information detected by the detecting device 116 can be directly sent to the display 117, the current environmental information is displayed by the display 117, and whether the current environmental information detected by the detecting device 116 is abnormal is detected by the detecting device 116, and when it is abnormal, the buzzer is controlled to be in working state.

[0061] In another embodiment, the low-melting-point substance storage device 10 further comprises a controller (not shown) arranged inside the protective shell 141, and the controller is electrically connected with the battery pack 142, the detecting device 116, the display 117 and the buzzer respectively, so that the current environmental information detected by the detecting device 116 is sent to the display 117 by the controller, the current environmental information is displayed by the display 117, and whether the current environmental information detected by the detecting device 116 is abnormal is detected by the controller, and when it is abnormal, the buzzer is controlled to be in working state.

[0063] In summary, the low-melting-point substance storage device 10 disclosed in the present application is used to store a substance to be stored (for example, a low-melting-point metal material) and keep the substance to be stored in a solid state, and the current ambient temperature where the low-melting-point substance storage device 10 is located is higher than the melting point of the substance to be stored, which can prevent the low-melting-point metal material from being oxidized by oxygen and polluted by water vapor. At the same time, the low-melting-point substance storage device 10 has a small overall volume, is convenient to carry and transport, and, compared with the prior art, does not need to use a special refrigerated transport vehicle for transportation, which not only can save transportation costs, but also can be recycled and used multiple times, thereby saving the costs of a low-melting-point metal material manufacturer.
