[0029] Please see Figures 1 to 3 This application provides a storage device 100, which can be used to store chemical materials and improve storage safety. The chemical materials can be hydrofluoric acid or other chemical materials.

[0030] The storage device 100 includes a water tank 110, a storage tank 130, a first heat exchanger 150, and a second heat exchanger 170.

[0031] The water tank 110 is used to contain the first heat exchange medium, which can be water or other liquid heat exchange media. In some other embodiments, the first heat exchange medium can also be a gaseous heat exchange medium. For ease of description, the following explanation will use a liquid heat exchange medium as the first heat exchange medium.

[0032] Storage tank 130 is used to contain chemical materials, such as hydrofluoric acid.

[0033] Storage tank 130 is partially housed within water tank 110. The tank wall of storage tank 130 is used for heat exchange between chemical materials and the first heat exchange medium, thereby adjusting the temperature of the chemical materials and the storage tank 130 so that storage tank 130 can better store chemical materials.

[0034] The first heat exchange medium can exchange heat with the chemical material through the tank wall of the storage tank 130 to raise or lower the temperature of the chemical material and the inside of the storage tank 130, which helps the storage tank 130 to better store the chemical material.

[0035] The first heat exchanger 150 is at least partially disposed within the water tank 110 for heating the first heat exchange medium, thereby increasing the temperature within the chemical materials and storage tank 130, which helps to improve the situation where chemical materials fail to store due to excessively low temperatures.

[0036] The second heat exchanger 170 is at least partially located inside the water tank 110 to cool the first heat exchange medium, thereby reducing the temperature inside the chemical materials and storage tank 130 and helping to improve the situation where chemical materials fail due to excessive temperature.

[0037] The storage device 100 provided in this application embodiment can heat and cool the temperature inside the storage tank 130, reduce the impact of ambient temperature on chemical materials, meet the different storage temperature requirements of different chemical materials, and expand the application range of the storage device 100.

[0038] As an example, taking hydrofluoric acid as a chemical material, the storage temperature of hydrofluoric acid can be controlled between ≥18℃ and ≤30℃. When the temperature inside storage tank 130 is <18℃, hydrofluoric acid may become viscous, affecting its flowability, or it may freeze, affecting its purity. When the temperature of hydrofluoric acid is >30℃, the water in the hydrofluoric acid is prone to evaporation or reaction with other impurities, affecting its purity. The first heat exchanger 150 can heat the first heat exchange medium when the ambient temperature is below 18℃ to raise the temperature of the chemical material and storage tank 130 to above 18℃. The second heat exchanger 170 can cool the first heat exchange medium when the ambient temperature is above 30℃ to lower the temperature of the chemical material and storage tank 130 to below 30℃.

[0039] In some embodiments, the second heat exchanger 170 may include a cooling element 171 and a heat exchange tube 173.

[0040] The cooling unit 171 can be installed outside the water tank 110.

[0041] As an example, both the water tank 110 and the cooling unit 171 can be placed on the ground or in other locations. The water tank 110 and the cooling unit 171 can be spaced apart or in contact with each other.

[0042] As another example, the cooling unit 171 can be installed on the outer wall of the water tank 110, thereby enabling the water tank 110 and the cooling unit 171 to be integrated, which facilitates the handling of the storage device 100 and reduces the space occupied by the storage device 100.

[0043] The cooling unit 171 can be used to provide a second heat exchange medium, the temperature of which can be lower than that of the first heat exchange medium.

[0044] The second heat exchange medium can be water or other liquid heat exchange media. In some other embodiments, the second heat exchange medium can also be a gaseous heat exchange medium. For ease of description, the following explanation will use a liquid heat exchange medium as an example.

[0045] As an example, the cooling unit 171 can be a refrigeration system, which may include a condenser, evaporator, compressor, expansion valve, etc. The specific connection methods are detailed in existing technology and will not be elaborated further. The refrigeration system can provide a second heat exchange medium at a lower temperature.

[0046] As another example, the cooling unit 171 can also be a cold storage device, as detailed in subsequent embodiments.

[0047] The heat exchange tube 173 can be connected to the outlet end of the cooling component 171 and partially penetrates the water tank 110. The cooling component 171 can be used to supply the second heat exchange medium to the heat exchange tube 173. The tube wall of the heat exchange tube 173 is used for heat exchange between the first heat exchange medium and the second heat exchange medium, thereby reducing the temperature of the first heat exchange medium to indirectly reduce the temperature inside the chemical materials and storage tank 130.

[0048] As an example, the cooling unit 171 may only have an outlet end. One end of the heat exchange tube 173 may be connected to the outlet end of the cooling unit 171, and the other end of the heat exchange tube 173 may be exposed outside the water tank 110 after passing through it, so as to discharge the second heat exchange medium after the heat exchange is heated. This helps to improve the cooling effect of the cooling unit 171 and can prevent the heated second heat exchange medium from affecting the cooling effect of the cooling unit 171.

[0049] As another example, the cooling element 171 may have an inlet end and an outlet end. The two ends of the heat exchange tube 173 may be connected to the outlet end and the inlet end of the cooling element 171 respectively to form a cooling cycle, thereby reusing the second heat exchange medium, which helps to reduce the amount of the second heat exchange medium used and improves the energy-saving effect of the storage device 100.

[0050] In some embodiments, the cooling unit 171 may include a cold storage tank 1711, which may be used to contain a second heat exchange medium.

[0051] The second heat exchange medium can be added to the cold storage tank 1711 manually or by machine.

[0052] As an example, the top of the cold storage tank 1711 may be provided with a feed inlet, which can serve as an inlet for adding a second heat exchange medium into the cold storage tank 1711.

[0053] The two ends of the heat exchange tube 173 can be connected to the inlet end and the outlet end of the cold storage tank 1711 respectively, and the heat exchange tube 173 is partially located inside the water tank 110. The cold storage tank 1711 is used to supply the second heat exchange medium to the heat exchange tube 173, so that the second heat exchange medium can be reused, which helps to reduce the amount of the second heat exchange medium used and can reduce the frequency of adding the second heat exchange medium.

[0054] As an example, the second heat exchange medium can have three states: solid, liquid, and solid-liquid mixture. The solid second heat exchange medium can refer to ice, the liquid second heat exchange medium can refer to cryogenic water, and the solid-liquid mixture second heat exchange medium can refer to an ice-water mixture. When adding the second heat exchange medium to the cold storage tank 1711, ice can be added. After the ice partially melts, it forms an ice-water mixture. The cryogenic water in the ice-water mixture can flow from the outlet of the cold storage tank 1711 to the heat exchange tube 173 to exchange heat with the first heat exchange medium. The heated second heat exchange medium enters the cold storage tank 1711 from the inlet. At this time, the heated second heat exchange medium can melt the ice in the cold storage tank 1711 to form an ice-water mixture, thus enabling the reuse of the second heat exchange medium without the need for an additional ice-melting step, which helps to save energy.

[0055] In some embodiments, the portion of the heat exchange tube 173 located inside the water tank 110 may be bent to increase the contact area between the tube wall of the heat exchange tube 173 and the first heat exchange medium, thereby improving the heat exchange effect and helping the first heat exchange medium to cool down more quickly and evenly.

[0056] The specific bending shape of the heat exchange tube 173 can be set according to requirements, and this application does not limit it.

[0057] In some embodiments, the portion of the heat exchange tube 173 located inside the water tank 110 can be spaced apart from the storage tank 130, thereby preventing the heat exchange tube 173 from directly contacting the tank wall of the storage tank 130, which helps to prevent a sudden drop in the internal temperature of the storage tank 130 from affecting the storage effect of chemical materials.

[0058] In some embodiments, the first heat exchanger 150 may adopt a structure substantially the same as that of the second heat exchanger 170. The first heat exchanger 150 may include a heating element and a heat exchange tube. The heating element may provide a third heat exchange medium with a temperature higher than that of the first heat exchange medium. The heat exchange tube may be connected to the outlet end of the heating element and partially penetrate into the water tank 110. The heating element is used to supply the third heat exchange medium to the heat exchange tube. The tube wall of the heat exchange tube may be used for heat exchange between the first heat exchange medium and the third heat exchange medium.

[0059] The specific structure of the heating element can refer to the specific structure of the cooling element 171. The only difference is that the heating element is used to provide a high-temperature third heat exchange medium, while the cooling element 171 is used to provide a low-temperature second heat exchange medium. The shape of the heat exchange tube and the connection method with the heating element can refer to the heat exchange tube 173 in the above embodiment, and will not be described again.

[0060] In some embodiments, the first heat exchanger 150 can be an electric heater, which can be installed in the water tank 110, so that the electric heater can directly heat the first heat exchange medium, thereby improving the heating speed and making the structure simpler and the production cost lower.

[0061] The number of electric heaters can be one or more, with "more" referring to two or more. When there are multiple electric heaters, the first heat exchange medium can be heated more quickly and evenly.

[0062] In some embodiments, the electric heater can be installed on the inner wall of the water tank 110, which helps to fix the electric heater and avoid direct contact between the electric heater and the storage tank 130, which could lead to a sudden increase in temperature of the chemical materials and inside the storage tank 130.

[0063] In some embodiments, the storage device 100 may further include a support plate 175, which may be connected to the outer wall of the water tank 110. The cooling component 171 may be installed on the top of the support plate 175, thereby allowing the cooling component 171 to be installed on the water tank 110 via the support plate 175. This helps to integrate the water tank 110 and the cooling component 171, making it easier to transport the storage device 100.

[0064] Specifically, the cold storage tank 1711 can be installed on top of the support plate 175. In some other embodiments, the cold storage tank 1711 can also be at least partially contained within the water tank 110, and the tank wall of the cold storage tank 1711 can also be used for heat exchange between the first heat exchange medium and the second heat exchange medium.

[0065] In some embodiments, the storage device 100 may further include a crash barrier 180, which may be partially connected to the outer wall of the water tank 110. The crash barrier 180 may have a first end and a second end, at least one of which may be a free end spaced apart from the outer wall of the water tank 110, so that when the storage device 100 is hit by an external object, the crash barrier 180 can share part of the impact force and reduce the damage to the water tank 110.

[0066] As an example, the crash barrier 180 may be partially connected to the outer wall of the water tank 110 in the middle between the first end and the second end, so that both the first end and the second end can be free ends spaced apart from the outer wall of the water tank 110. When the crash barrier 180 or the water tank 110 is subjected to an impact, the first end and the second end of the crash barrier 180 can play a buffering role to reduce the damage to the water tank 110.

[0067] In some embodiments, the storage device 100 may further include a temperature sensor 190 and a first controller 210.

[0068] The temperature sensor 190 can be installed inside the storage tank 130 to sense the temperature inside the storage tank 130.

[0069] The temperature sensor 190 can be a thermometer, a thermistor, a temperature measuring instrument, or other temperature sensor components. The number of temperature sensors 190 can be one or more. When there are multiple temperature sensors 190, the temperature inside the storage tank 130 can be sensed more accurately.

[0070] The first controller 210 can be located outside the water tank 110 and can communicate with the first heat exchanger 150.

[0071] The first controller 210 can be used to control the start and stop of the first heat exchanger 150 based on the temperature inside the storage tank 130 sensed by the temperature sensor 190, thereby enabling intelligent control of the first heat exchanger 150 without the need for manual operation of the first heat exchanger 150, which helps to control the temperature inside the chemical materials and storage tank 130 more stably and intelligently.

[0072] As an example, temperature sensor 190 is used to issue a first signal when the temperature inside storage tank 130 is ≤ a first preset temperature, and to issue a second signal when the temperature inside storage tank 130 is > the first preset temperature. First controller 210 is used to control first heat exchanger 150 to heat the first heat exchange medium based on the received first signal, and to control first heat exchanger 150 to stop heating the first heat exchange medium based on the received second signal. The first preset temperature can be set according to actual needs; for example, taking hydrofluoric acid as a chemical material, the first preset temperature can be 18°C.

[0073] In some embodiments, the first controller 210 may be provided with a first display module, which is used to display at least one of the temperature sensed by the temperature sensor 190, the operating status of the first heat exchanger 150, and the operating status of the second heat exchanger 170, so that the user can easily observe at least one of the temperature sensed by the temperature sensor 190, the operating status of the first heat exchanger 150, and the operating status of the second heat exchanger 170 in real time through the first display module.

[0074] As an example, the first controller 210 can be located on the outer wall of the water tank 110, making it easier for the user to view the first display module. The first display module can be a display screen.

[0075] In some embodiments, the storage device 100 may further include a second controller 230, which may be located outside the water tank 110 and communicate with the second heat exchanger 170. The second controller 230 is used to control the start and stop of the second heat exchanger 170 according to the temperature inside the storage tank 130 sensed by the temperature sensor 190, thereby enabling intelligent control of the second heat exchanger 170 without manual operation, which helps to control the temperature of chemical materials and the storage tank 130 more stably and intelligently.

[0076] As an example, temperature sensor 190 is used to send a third signal if the temperature inside storage tank 130 is greater than or equal to a second preset temperature, and to send a fourth signal if the temperature inside storage tank 130 is less than the second preset temperature; second controller 230 is used to control second heat exchanger 170 to cool the first heat exchange medium based on the received third signal, and to control first heat exchanger 150 to stop cooling the first heat exchange medium based on the received third signal. The second preset temperature can be set according to actual needs, and the first preset temperature can be lower than the second preset temperature. For example, taking hydrofluoric acid as a chemical material, the first preset temperature can be 18°C, and the second preset temperature can be 30°C.

[0077] In some embodiments, the second controller 230 may be provided with a second display module, which is used to display at least one of the temperature sensed by the temperature sensor 190, the operating status of the first heat exchanger 150 and the operating status of the second heat exchanger 170, so that the user can easily observe at least one of the temperature sensed by the temperature sensor 190, the operating status of the first heat exchanger 150 and the operating status of the second heat exchanger 170 in real time through the second display module.

[0078] As an example, the second controller 230 can be located on the outer wall of the water tank 110 or the side wall of the support plate 175, making it easier for the user to view the second display module. The second display module can be a display screen.

[0079] In some embodiments, the storage tank 130 may include a tank body 131 and a lid 133.

[0080] The tank body 131 may have a receiving cavity 1311, which has an open opening 1313, through which chemical materials can be added to the receiving cavity 1311.

[0081] The bottom of the tank 131 can be housed in the water tank 110, and the tank wall at the bottom of the tank 131 can be used for heat exchange between chemical materials and the first heat exchange medium.

[0082] The top of the tank 131 can be exposed above the top of the water tank 110, and the opening 1313 can be located on the top of the storage tank 130 to facilitate the addition of chemical materials into the receiving cavity 1311 from the opening 1313.

[0083] The cover 133 can be used to open or close the cavity 1313. The temperature sensor 190 can be disposed on the cover 133, thereby reducing the contact between the temperature sensor 190 and chemical materials, helping to reduce the corrosion of the temperature sensor 190 by chemical materials, and extending the service life of the temperature sensor 190.

[0084] In some embodiments, the storage tank 130 may further include a sealing ring 250, which may be connected to the cover 133 and used to abut and seal between the tank 131 and the cover 133 when the cover 133 is placed on the tank 131, so as to seal the accommodating cavity 1311 and help improve the sealing effect of the storage tank 130.

[0085] In some embodiments, the sealing ring 250 may be configured in a double-layer manner to improve the sealing effect of the sealing ring 250.

[0086] As an example, the sealing ring 250 may include a first annular sealing portion and a second annular sealing portion. One axial end of the first annular sealing portion may be connected to the cover 133, and the second annular sealing portion may protrude from the other axial end of the first annular sealing portion. The outer circumferential diameter of the second annular sealing portion may be smaller than the outer circumferential diameter of the first annular sealing portion. The top of the tank 131 has an annular end face, and the tank 131 has an inner circumferential wall connected to the annular end face. When the cover 133 is placed on the tank 131, the end face of the first annular sealing portion may abut against the annular end face, and the outer circumferential surface of the second annular sealing portion may abut against the inner circumferential wall of the tank 131, thereby achieving a double-layer seal and improving the sealing effect of the sealing element.

[0087] Please see Figure 1 and Figure 4 In some embodiments, the storage device 100 may further include a pressure relief pipe 270 and a pressure relief assembly 290.

[0088] The pressure relief pipe 270 can be connected to the part of the storage tank 130 located outside the water tank 110, thus eliminating the need to provide a hole structure on the water tank 110 for the pressure relief pipe 270 to pass through, which helps to improve the integrity of the outer wall of the water tank 110 and reduce the possibility of leakage of the water tank 110.

[0089] The pressure relief pipe 270 can connect the internal space of the storage tank 130 and the external space outside the storage tank 130, so that the gas inside the storage tank 130 can be discharged to the external space through the pressure relief pipe.

[0090] The pressure relief assembly 290 can be used to open or close the pressure relief pipe 270, thereby enabling the pressure relief assembly 290 to control the gas discharge from the storage tank 130 and to seal the internal space of the storage tank 130 after the gas is discharged.

[0091] The pressure relief assembly 290 can communicate with the temperature sensor 190.

[0092] The pressure relief assembly 290 is used to open or close the pressure relief pipe 270 according to the temperature change inside the storage tank 130 sensed by the temperature sensor 190, thereby realizing intelligent pressure relief without the need for manual control of the pressure relief assembly 290 by the user, which helps the storage tank 130 to store chemical materials more stably.

[0093] As an example, the temperature sensor 190 is used to issue a fifth signal if the temperature change inside the storage tank 130 within a preset time period is greater than or equal to a preset temperature value, and to issue a sixth signal if the temperature change inside the storage tank 130 within a preset time period is less than the preset temperature value. The pressure relief assembly 290 is used to open the pressure relief pipe 270 upon receiving the fifth signal and to close the pressure relief pipe 270 upon receiving the sixth signal, thereby releasing excess gas generated by the chemical materials due to large temperature changes. This helps to ensure the stability of the gas pressure inside the storage tank 130 and improves the safety of the storage device 100.

[0094] Both the preset time period and the preset temperature value can be set according to actual needs. For example, the temperature sensor 190 is used to issue a fifth signal when it senses a temperature change ≥5°C inside the storage tank 130 within 1 minute, and to issue a sixth signal when it senses a temperature change <5°C inside the storage tank 130 within 1 minute.

[0095] It should be noted that the temperature controller can continuously sense the temperature value inside the storage tank 130 within a preset time period, or it can sense the temperature value inside the storage tank 130 at a preset frequency.

[0096] In some embodiments, the pressure relief assembly 290 may be a solenoid valve or other electrically operated valve.

[0097] In some embodiments, the pressure relief assembly 290 may include a telescopic drive 291 and a switch 293.

[0098] The pressure relief pipe 270 may have an opening groove 271 in its wall, and the switch 293 may be inserted into the pressure relief pipe 270 through the opening groove 271.

[0099] As an example, the pressure relief pipe 270 may extend laterally, and the bottom wall of the pressure relief pipe 270 may be provided with an opening groove 271.

[0100] The switch 293 can have an open position and a closed position.

[0101] When the switch 293 is in the closed position, the outer peripheral wall of the switch 293 contacts the inner wall of the pressure relief pipe 270 to close the pressure relief pipe 270; when the switch 293 is in the open position, the outer peripheral wall of the switch 293 disengages from the inner wall of the pressure relief pipe 270 to open the pressure relief pipe 270.

[0102] As an example, the shape of the switch element 293 can be set according to the cross-sectional shape of the pressure relief pipe 270. For example, when the cross-sectional shape of the pressure relief pipe 270 is annular, the switch element 293 can be in the shape of a circular plate or a sphere. When the switch element 293 is in the closed position, the outer peripheral wall of the switch element 293 can fit against or abut against the inner peripheral wall of the pressure relief pipe 270, thereby closing the pressure relief pipe 270 and sealing the internal space of the storage tank 130. When the switch element 293 is in the open position, the outer peripheral wall of the switch element 293 can detach from the inner peripheral wall of the pressure relief pipe 270, thereby forming a gap between the outer peripheral wall of the switch element 293 and the inner peripheral wall of the pressure relief pipe 270 to allow gas to pass through, so that the gas in the storage tank 130 can be discharged.

[0103] The telescopic drive 291 can be installed on the top of the water tank 110 and located below the pressure relief pipe 270.

[0104] As an example, the top of the water pipe may have an upwardly protruding installation chamber 111, and the top of the installation chamber 111 may have an opening 1111, which may be located below the opening slot 271. A telescopic drive 291 may be disposed inside the installation chamber 111, and the telescopic end of the telescopic drive 291 may pass through the opening 1111 for lifting and lowering.

[0105] The telescopic drive 291 is connected to the switch 293 at its telescopic end. The telescopic drive 291 is also connected to the temperature sensor 190. The telescopic drive 291 is used to drive the switch 293 to rise to the closed position or fall to the open position according to the temperature change inside the storage tank 130 sensed by the temperature sensor 190. This enables intelligent pressure relief without requiring manual control of the telescopic drive 291 by the user, which helps the storage tank 130 to store chemical materials more stably.

[0106] As an example, the telescopic drive 291 is used to drive the switch 293 to the open position when a fifth signal is received, and to drive the switch 293 to the closed position when a sixth signal is received.

[0107] In some embodiments, the telescopic drive 291 may be a hydraulic component, and the telescopic drive 291 may include a hydraulic control module 2911 and a hydraulic rod 2913. The hydraulic control module 2911 may be communicatively connected to the temperature sensing module.

[0108] As an example, the hydraulic control module 2911 can be used to control the hydraulic rod 2913 to lower the switch 293 to the open position according to the received fifth signal, and to control the hydraulic rod 2913 to raise the switch 293 to the closed position according to the received sixth signal.

[0109] Please see Figure 1 In some embodiments, the top wall of the water tank 110 may be provided with an opening through which the storage tank 130 can be installed in the water tank 110, such that the bottom of the storage tank 130 is accommodated inside the water tank 110 and the top of the storage tank 130 is exposed outside the water tank 110.

[0110] Storage tank 130 and water tank 110 can be installed in a fixed manner or in a detachable manner.

[0111] In some embodiments, the storage device 100 may further include a discharge pipe 310, one end of which may be connected to the bottom of the tank 131, and the other end may be exposed outside the water tank 110 after passing through the water tank 110. The discharge pipe 310 may be used to discharge chemical materials from the accommodating cavity 1311, so that users can take the chemical materials from the accommodating cavity 1311 through the discharge pipe 310.

[0112] Understandably, a switch structure can be provided at the end of the discharge pipe 310 exposed outside the water tank 110 to open or close the discharge pipe 310.

[0113] In some embodiments, the storage device 100 may further include an infusion pipe 330, which may be connected to the water tank 110 and communicates the water tank 110 with the external space. The infusion pipe 330 may serve as a conduit for delivering and discharging the first heat exchange medium into the water tank 110.

[0114] The position of the infusion tube 330 on the water tank 110 can be set according to requirements.

[0115] Understandably, the infusion tube 330 can also be equipped with a switch structure to open or close the infusion tube 330.

[0116] In some embodiments, the storage device 100 may further include support feet 350, which may be distributed at the bottom of the water tank 110 to support the water tank 110 and help prevent the water tank 110 from directly contacting the ground or other placement locations.

[0117] The number of support feet 350 can be three or more, to provide more stable support for the water tank 110.

[0118] In the storage device 100 provided in this embodiment, by partially housing the storage tank 130 within the water tank 110, the tank wall of the storage tank 130 can be used for heat exchange between the chemical materials and the first heat exchange medium within the storage tank 130, thereby adjusting the temperature of the chemical materials and the storage tank 130. By at least partially arranging the first heat exchanger 150 within the water tank 110 to heat the first heat exchange medium, and by at least partially arranging the second heat exchanger 170 within the water tank 110 to cool the first heat exchange medium, heating and cooling of the first heat exchange medium can be achieved, thereby indirectly heating and cooling of the chemical materials and the storage tank 130. This reduces the impact of ambient temperature on the chemical materials, meets the different storage temperature requirements of different chemical materials, expands the application range of the storage device 100, and helps the storage device 100 to better store chemical materials.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
