Description

Technical Field

[0001] The invention relates to the technical field of gas storage tanks, in particular to a gas storage tank with an automatic temperature adjustment function. Background Art

[0002] In modern industry and life, gas storage tanks are widely used in various fields, such as petrochemical industry, energy storage, machinery manufacturing and civil gas supply.

[0003] In actual applications, the gas temperature in the gas tank will be affected by changes in the external ambient temperature and processes such as gas compression and release. When the external ambient temperature is too high, the gas temperature in the gas tank will also rise. The increase in gas temperature will increase the gas pressure. If it exceeds the design pressure limit of the gas tank, it may cause a safety accident and pose a serious threat to personnel and equipment.

[0004] For example, in the petrochemical industry, high temperatures may cause the pressure of flammable and explosive gases in gas tanks to rise sharply. Once a leak or explosion occurs, the consequences will be disastrous. Therefore, gas tanks need to have temperature regulation functions to prevent accidents.

[0005] The gas tank in the prior art senses the temperature through a temperature sensor and adjusts the temperature of the tank body. However, as the temperature sensor is used for a long time, the performance of components such as resistance and capacitance may change, resulting in a decrease in the measurement accuracy of the sensor or complete failure. The temperature sensor may malfunction, such as being damaged or malfunctioning. Once the sensor fails, it cannot sense the temperature of the gas tank normally, causing the temperature regulation system to fail to work.

[0006] In view of this, this application is hereby filed. Summary of the invention

[0007] The object of the present invention is to provide a gas storage tank with an automatic temperature adjustment function to solve the problems raised in the above background technology.

[0008] In order to solve the above technical problems, the present invention provides a gas storage tank with automatic temperature adjustment function, including a gas cylinder, a cooling assembly and a connecting pipe connected to the gas cylinder, and also includes a mounting pipe, which is arranged on the side of the connecting pipe and is connected to the connecting pipe; a piston, which is arranged in the mounting pipe and can slide axially along the mounting pipe; a water pump switch, which is installed on the inner bottom surface of the top end of the mounting pipe and is used to control the start and stop of the cooling assembly.

[0009] Furthermore, the installation tube is divided into two unconnected upper and lower sections, one end of the piston is arranged in the lower section, and the other end passes through the installation tube and is formed between the two sections of the installation tube, and the water pump switch is installed on the bottom surface of the upper section of the installation tube.

[0010] Furthermore, a connecting ring is arranged on the outer wall of the other end of the piston, a trigger sheet is arranged on the side wall of the connecting ring, and a second switch is arranged on the top surface of the lower section of the mounting tube.

[0011] Furthermore, a spring is arranged on the bottom surface of the connecting ring, the other end of the spring is fixedly connected to the top surface of the lower section of the mounting tube, and the spring is sleeved around the outer wall of the piston.

[0012] Furthermore, a heat-insulating outer shell is provided on the outer side of the gas cylinder, and the connecting pipe is inserted from the top surface of the heat-insulating outer shell to communicate with the gas cylinder.

[0013] Furthermore, the cooling assembly includes a water tank and a water pipe. A water pump is provided on the side of the water tank, and a circulation coil is provided on the outside of the gas cylinder. There are two water pipes, which respectively connect the two ends of the circulation coil with the water pumping end of the water pump and the inner bottom end of the water tank.

[0014] Furthermore, the water pipe and the circulation coil are detachably connected via a docking piece, and the docking piece includes an external threaded end fixedly connected to both ends of the circulation coil, and an internal threaded sleeve radially rotatably installed on the water pipe.

[0015] Furthermore, the installation pipe is connected to the connecting pipe through a connecting pipe, an anti-corrosion thermal pad is provided at the connection between the installation pipe and the connecting pipe, and a heat expansion gas is filled between the anti-corrosion thermal pad and the piston.

[0016] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, by arranging a piston and a water pump switch, when the temperature of the gas cylinder rises, the cooling component can automatically start to cool the gas cylinder, and the cold water in the water tank is pumped into the circulating coil for heat exchange through the water pump, thereby taking away the heat from the gas cylinder, thereby achieving effective cooling of the gas cylinder and preventing the gas from being dangerous due to excessive temperature.

[0017] In the present invention, by arranging a piston and a second switch, when the temperature of the gas cylinder is low and negative pressure is generated, the water pump and the heating function can be automatically started to heat the water in the water tank. The heated water heats the gas cylinder and the gas therein through the circulation coil, thereby preventing the gas cylinder from cracking due to excessively low temperature.

[0018] In the present invention, for gas cylinders storing highly corrosive gases, an anti-corrosion thermal pad can be provided to isolate the piston from the gas cylinder, which can not only detect the temperature and trigger corresponding functions, but also prevent the corrosive gas from directly contacting the piston, thereby reducing the service life of the piston.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-7 , the present invention provides a technical solution: A gas storage tank with automatic temperature adjustment function comprises a gas cylinder 1, a cooling assembly and a connecting pipe 3 connected to the gas cylinder 1. The outer side of the gas cylinder 1 is provided with an insulating outer shell 101, and the insulating outer shell 101 is made of rock wool board material, which can effectively isolate the transfer of temperature. The connecting pipe 3 is inserted from the top surface of the insulating outer shell 101 and connected to the gas cylinder 1.

[0023] The provision of the heat-insulating outer shell 101 can isolate the gas cylinder 1 from the external environment, thereby reducing the impact of high or low room temperature in winter or summer on the gas in the gas cylinder 1.

[0024] Optionally, the connection between the heat-insulating housing 101 and the gas cylinder 1 can be evacuated. The vacuum environment can further isolate temperature transfer on the basis of the above-mentioned effects, thereby improving the temperature insulation effect of the device.

[0025] The cooling assembly includes a water tank 2 and a water pipe 202. The water tank 2 has a built-in refrigeration and heating system. A water pump 201 is provided on the side of the water tank 2. A circulating coil 203 is provided on the outer side of the gas cylinder 1. There are two water pipes 202, which respectively connect the two ends of the circulating coil 203 with the water pumping end of the water pump 201 and the inner bottom end of the water tank 2.

[0026] By adopting the above design, when the gas cylinder 1 needs to be cooled, the cold water in the water tank 2 can be pumped into the circulation coil 203 through the water pump 201 through the water pipe 202, circling around the outside of the gas cylinder 1 to exchange heat, taking away the heat thereon, and then entering the water tank 2 for re-refrigeration, repeating the cycle to cool down.

[0027] The water pipe 202 and the circulation coil 203 are detachably connected via a docking piece 204 , and the docking piece 204 includes an external threaded end fixedly connected to both ends of the circulation coil 203 , and an internal threaded sleeve radially rotatably installed on the water pipe 202 .

[0028] The above design enables the water pipe 202 to be separated from the circulation coil 203 when the cooling and heating system in the water tank 2 needs to be maintained, and the water tank 2 can be transported away alone for inspection and maintenance.

[0029] The connecting pipe 3 is connected to an air pipe 301, and a valve 302 for controlling the opening and closing of the air pipe 301 is provided at the top of the connecting pipe 3. The air pipe 301 is connected to an injection or gas-using device, and a sealing gasket 5 is provided at the connection between the air pipe 301 and the device.

[0030] It also includes a mounting tube 401, which is arranged on the side of the connecting tube 3 and is connected to the connecting tube 3; a piston 402, which is arranged in the mounting tube 401 and can slide axially along the mounting tube 401; and a water pump switch 403, which is installed on the inner bottom surface of the top end of the mounting tube 401 and is used to control the start and stop of the cooling component.

[0031] The above design ensures that when the temperature of the gas cylinder 1 rises, the volume of the gas will expand due to the heat, and flow into the installation tube 401 from the connection between the installation tube 401 and the connecting tube 3, pushing the piston 402 to rise. When the piston 402 rises, it will conflict with the water pump switch 403, starting the cooling component to cool down.

[0032] This design does not have complex electronic components, its production cost is low, and its structure is relatively simple. It is mainly made of solid metal materials. Due to its simplicity of structure and the relative simplicity of mechanical movement, it does not have complex electronic components and fine circuit structure, and is not easily affected by factors such as electromagnetic interference and voltage fluctuations, which reduces the possibility of failure. The possibility of accidents during use is low.

[0033] Moreover, the maintenance of the piston 402 is relatively simple, mainly including regular inspection of lubrication conditions, replacement of worn parts, etc. Due to its simple structure, maintenance work is relatively easy to carry out, and potential problems can be discovered and solved in time, thereby reducing the probability of failure.

[0034] Furthermore, since its detection function is performed through the thermal expansion of the gas in the gas cylinder 1, its detection and triggering accuracy is accurate and is not affected by the inspection and maintenance experience of the staff.

[0035] Furthermore, the mounting tube 401 is divided into two unconnected upper and lower sections, one end of the piston 402 is arranged in the lower section, and the other end passes through the mounting tube 401 and is formed between the two sections of the mounting tube 401, and the water pump switch 403 is installed on the bottom surface of the upper section of the mounting tube 401.

[0036] By splitting the installation pipe 401, the part of the installation pipe 401 where the water pump switch 403 is installed is no longer connected to the connecting pipe 3, so that the inspection and maintenance of the water pump switch 403 are more convenient.

[0037] Furthermore, a connecting ring 404 is provided on the outer wall of the other end of the piston 402, and a spring 405 is provided on the bottom surface of the connecting ring 404. The other end of the spring 405 is fixedly connected to the top surface of the lower section of the mounting tube 401, and the spring 405 is sleeved around the outer wall of the piston 402.

[0038] The design of spring 405 ensures that when the gas in gas cylinder 1 expands due to heat, piston 402 will not be triggered before its expansion force overcomes the elastic force of spring 405, which can reduce the number of movements of piston 402, reduce mechanical fatigue of piston 402, and increase the service life of piston 402. By replacing spring 405, the triggering temperature of the device can be adjusted to adapt to the expansion coefficient and storage temperature of different gases.

[0039] Embodiment 3, based on embodiment gas cylinder 1, a trigger sheet 406 is provided on the side wall of the connecting ring 404, and a second switch 407 is provided on the top surface of the lower section of the mounting tube 401. The second switch 407 is electrically connected to the water pump 201 and is also electrically connected to the switching function of the cooling and heating system.

[0040] The above design ensures that when in use, if the temperature in the gas cylinder 1 is low, the gas will contract when it is cooled, generating negative pressure, which will drive the piston 402 to descend. When the piston 402 descends, it will drive the trigger sheet 406 to descend, triggering the second switch 407, starting the water pump 201, switching the cooling and heating system functions, and heating the water in the water tank 2, thereby heating the gas cylinder 1 and the gas therein, and preventing the gas cylinder 1 from cracking due to excessively low temperature.

[0041] Embodiment 3, based on the embodiment gas cylinder 1, optionally, the mounting tube 401 is connected to the connecting tube 3 through the connecting tube 4, and an anti-corrosion thermal pad 408 is provided at the connection between the mounting tube 401 and the connecting tube 4, and the space between the anti-corrosion thermal pad 408 and the piston 402 is filled with thermal expansion gas.

[0042] By adopting the above design, when the gas stored in the gas cylinder 1 is highly corrosive, the gas can be isolated from the piston 402 through the anti-corrosion thermal pad 408. The heat-expanding gas is driven to contract or expand through the transfer of temperature, thereby preventing the corrosive gas from directly contacting the piston 402 and reducing its service life.

[0043] Working principle: The thermal insulation shell 101 is made of rock wool board and is sleeved on the outside of the gas cylinder 1 to isolate the gas cylinder 1 from the external environment and reduce the impact of room temperature on the gas in the gas cylinder 1 in winter and summer. The connection between the thermal insulation shell 101 and the gas cylinder 1 can be evacuated to further isolate the temperature transfer and improve the temperature isolation effect.

[0044] When the temperature of the gas cylinder 1 rises, the volume of the gas expands due to heat. The expanded gas flows into the installation pipe 401 from the connection between the installation pipe 401 and the connecting pipe 3, pushing the piston 402 up. After the piston 402 rises to a certain position, it will conflict with the water pump switch 403 installed on the inner bottom surface of the top of the installation pipe 401, and start the cooling component. The water pump 201 in the cooling component pumps the cold water in the water tank 2 into the circulation coil 203 outside the gas cylinder 1 through the water pipe 202. The cold water swirls through the outside of the gas cylinder 1 in the circulation coil 203 to exchange heat and take away the heat from the gas cylinder 1. The water after heat exchange returns to the water tank 2 through the water pipe 202 for refrigeration. This reciprocating cycle achieves cooling of the gas cylinder 1.

[0045] The water pipe 202 and the circulation coil 203 are detachably connected via a docking piece 204. The docking piece 204 includes an externally threaded end fixedly connected to both ends of the circulation coil 203 and an internally threaded sleeve radially rotatably installed on the water pipe 202. When the cooling and heating systems in the water tank 2 need to be maintained, the water pipe 202 can be separated from the circulation coil 203, and the water tank 2 can be transported away separately for inspection and maintenance.

[0046] When the temperature in the gas cylinder 1 is low and the gas contracts when it is cooled, generating negative pressure, the piston 402 will be driven down. When the piston 402 descends, the trigger sheet 406 on the side wall of the connecting ring 404 will be driven down, triggering the second switch 407. The second switch 407 starts the water pump 201 and switches the functions of the cooling and heating systems at the same time to heat the water in the water tank 2. The heated water heats the gas cylinder 1 and the gas therein through the circulation coil 203 to prevent the gas cylinder 1 from cracking due to the low temperature.

[0047] When the gas stored in the gas cylinder 1 is highly corrosive, the mounting tube 401 is connected to the connecting tube 3 via the connecting tube 4, and an anti-corrosion thermal pad 408 is provided at the connection between the mounting tube 401 and the connecting tube 4. The anti-corrosion thermal pad 408 isolates the gas from the piston 402, and drives the heat-expanding gas filled between the anti-corrosion thermal pad 408 and the piston 402 to contract or expand through temperature transfer. The contraction or expansion of the heat-expanding gas pushes the piston 402 to move, thereby realizing temperature detection and triggering corresponding cooling or heating functions, while preventing corrosive gas from directly contacting the piston 402, thereby reducing the service life of the piston 402.
