Description

Technical Field

[0001] This utility model relates to the field of storage tank safety technology, specifically to an explosion-proof storage tank with a pressure relief device. Background Technology

[0002] In industries such as chemical and energy, storage tanks are commonly used to store flammable, explosive, or high-pressure media. When the pressure inside a storage tank abnormally increases due to temperature changes, chemical reactions, or other factors, an explosion may occur if the pressure is not released in time.

[0003] Based on the above, the following problems were found: most of the current explosion-proof storage tank pressure relief devices are of a single structure, and they do not have pressure relief regulation function when in use, which makes it difficult to meet the safety requirements of modern industry for storage tanks.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an explosion-proof storage tank with a pressure relief device in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide an explosion-proof storage tank with a pressure relief device, so as to solve the problem mentioned in the background art that the pressure relief devices of current explosion-proof storage tanks are mostly of a single structure and do not have pressure relief and regulation functions during use, which makes it difficult to meet the safety requirements of modern industry for storage tanks.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] An explosion-proof storage tank with a pressure relief device includes a tank body. Several support frames are installed at the bottom of the tank body. Fixed seats are installed at the bottom ends of both sides of each support frame. A side frame is installed on one side of each pair of support frames. A retainer is installed at the top of each side frame. A pressure relief tank is installed inside the retainer. A connecting seat is installed on one end face of the tank body. A pressure relief mechanism is installed on one side of the connecting seat. The pressure relief mechanism includes a pressure relief pipe. A conical plug is slidably connected to the inner side of the pressure relief pipe. An exhaust port is opened on one side of the connecting seat. One end of the conical plug is inserted into the inner side of the exhaust port. An exhaust pipe is installed on one side of the pressure relief pipe. One end of the exhaust pipe is connected to one end face of the pressure relief tank. A threaded rod is rotatably connected to the inner side of the pressure relief pipe. A pressure adjusting plate is fitted onto the outer side of the threaded rod. A spring is installed at one end of the pressure adjusting plate. One end of the spring is fixedly connected to the other end of the conical plug.

[0008] Furthermore, a plurality of sliding rods are slidably connected to the inner side of the pressure regulating plate, and one end of each sliding rod is fixedly connected to the other end of the conical plug.

[0009] The beneficial effect of adopting the above-mentioned further solution is that several sliding rods are slidably connected to the inner side of the pressure regulating plate to guide the movement of the conical plug, ensuring that the conical plug can slide smoothly along the sliding rods during the pressure relief process, preventing deviation or jamming, and ensuring the reliability and stability of the pressure relief action.

[0010] Furthermore, a handle is provided on one end face of the pressure relief pipe, and one end of the handle is fixedly connected to one end of the threaded rod.

[0011] The beneficial effect of adopting the above-mentioned further solution is that by fixing one end of the throttle to one end of the threaded rod, the operator can easily drive the threaded rod to rotate by turning the throttle, thereby adjusting the position of the pressure regulating plate, changing the compression of the spring, and adjusting the pressure relief value.

[0012] Furthermore, a limiting plate is installed at the other end of the threaded rod.

[0013] The advantage of adopting the above-mentioned further solution is that by installing a limit plate at the other end of the threaded rod, it is possible to prevent the threaded rod from rotating excessively and causing the pressure regulating plate to fall out of the normal adjustment range.

[0014] Furthermore, sliders are installed on both sides of the pressure regulating plate, and a pair of sliding grooves are opened on the inner side of the pressure relief pipe. The outer side of the slider and the inner side of the sliding groove are slidably connected.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the sliding connection between the outer side of the slider and the inner side of the groove improves the moving stability of the pressure regulating plate.

[0016] Furthermore, valves are installed on the other end face of both the storage tank body and the pressure relief tank.

[0017] The beneficial effect of adopting the above-mentioned further solution is that, by installing valves on the other end face of both the storage tank body and the pressure relief tank, the entry and exit of the medium in the storage tank body and the pressure relief tank can be controlled respectively.

[0018] Furthermore, a pressure sensor is installed inside the tank body, and a control panel is installed on the other side of one of the support frames.

[0019] The beneficial effect of adopting the above-mentioned further solution is that, by installing a pressure sensor inside the tank body, the pressure sensor inside the tank body can monitor the pressure data inside the tank in real time and transmit the data to the control panel on one side of the support frame.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This explosion-proof storage tank with a pressure relief device achieves medium storage through the tank body. The support frame and fixed seat cooperate to provide stable support for the tank body, ensuring that the tank remains stable during use. The side frame and retainer are used to install the pressure relief tank, providing a support structure for the pressure relief system. The pressure relief pipe, conical plug, and exhaust pipe in the pressure relief mechanism constitute a pressure relief channel. When the internal pressure of the tank body exceeds the set value, the pressure pushes the conical plug to overcome the spring force, causing the exhaust port to open. Gas is discharged into the pressure relief tank through the exhaust pipe, achieving safe pressure relief and preventing the tank from exploding due to excessive pressure. The threaded rod and pressure adjusting plate can adjust the compression degree of the spring, thereby changing the pressure relief threshold to meet the pressure relief requirements under different storage media and operating conditions. Several sliding rods are slidably connected to the inner side of the pressure adjusting plate, providing guidance for the movement of the conical plug and ensuring that the conical plug can slide smoothly along the sliding rods during the pressure relief process, preventing deviation. To prevent displacement or jamming, and ensure the reliability and stability of the pressure relief action, a fixed connection is made between one end of a throttle and one end of a threaded rod. This allows the operator to easily rotate the threaded rod by turning the throttle, thereby adjusting the position of the pressure regulating plate, changing the spring compression, and adjusting the pressure relief value. A limit plate is installed at the other end of the threaded rod to prevent excessive rotation of the threaded rod from causing the pressure regulating plate to move out of its normal adjustment range. A sliding connection between the outer side of the slider and the inner side of the slide groove improves the stability of the pressure regulating plate's movement. Valves are installed on the other end faces of both the storage tank and the pressure relief tank, allowing for separate control of the inflow and outflow of the medium within each tank. A pressure sensor is installed inside the storage tank, enabling real-time monitoring of the pressure data within the tank and transmitting the data to a control panel on one side of the support frame. This invention effectively provides pressure relief and adjustment functions, meeting the safety requirements of modern industry for storage tanks and possessing high practical value.

[0027] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0028] Example 1

[0029] Please see Figures 1-5 This utility model provides a technical solution: an explosion-proof storage tank with a pressure relief device, comprising a tank body 1, a plurality of support frames 2 installed at the bottom end of the tank body 1, fixed seats 3 installed at the bottom ends of both sides of the support frames 2, a side frame 4 installed on one side of a pair of support frames 2, a retainer 5 installed at the top of the side frame 4, a pressure relief tank 6 installed inside the retainer 5, a connecting seat 8 installed on one end face of the tank body 1, and a pressure relief mechanism 9 installed on one side of the connecting seat 8. 9 includes a pressure relief pipe 901, with a conical plug 903 slidably connected to the inner side of the pressure relief pipe 901. An exhaust port 801 is provided on one side of the connecting seat 8. One end of the conical plug 903 is inserted into the inner side of the exhaust port 801. An exhaust pipe 902 is installed on one side of the pressure relief pipe 901, with one end of the exhaust pipe 902 connected to one end face of the pressure relief tank 6. A threaded rod 904 is rotatably connected to the inner side of the pressure relief pipe 901, and a pressure regulating plate 905 is fitted onto the outer side of the threaded rod 904. A spring 909 is installed at one end of the pressure regulating plate 905. One end of the spring 909 is fixedly connected to the other end of the conical plug 903. The storage tank body 1 is set up to realize the storage of the medium. The support frame 2 cooperates with the fixed seat 3 to provide stable support for the storage tank body 1 and ensure that the storage tank remains stable during use. The side frame 4 and the retainer 5 are used to install the pressure relief tank 6 and provide a support structure for the pressure relief system. The pressure relief pipe 901, the conical plug 903 and the exhaust pipe 902 in the pressure relief mechanism 9 form a pressure relief channel. When the internal pressure of the storage tank body 1 exceeds the set value, the pressure pushes the conical plug 903 to overcome the elastic force of the spring 909, so that the exhaust port 801 opens and the gas is discharged into the pressure relief tank 6 through the exhaust pipe 902 to achieve safe pressure relief and prevent the storage tank from exploding due to excessive pressure. The threaded rod 904 and the pressure regulating plate 905 can adjust the compression degree of the spring 909, thereby changing the pressure relief threshold and meeting the pressure relief requirements under different storage media and operating conditions.

[0030] Please see Figures 1-5Several sliding rods 906 are slidably connected to the inner side of the pressure regulating plate 905. One end of each sliding rod 906 is fixedly connected to the other end of the conical plug 903. A handle 908 is provided on one end face of the pressure relief pipe 901. One end of the handle 908 is fixedly connected to one end of the threaded rod 904. A limit plate 907 is installed on the other end of the threaded rod 904. Several sliding rods 906 are slidably connected to the inner side of the pressure regulating plate 905 to guide the movement of the conical plug 903, ensuring that the conical plug 903 can move along the sliding rods 906 during the pressure relief process. 6. Smooth sliding prevents deviation or jamming, ensuring the reliability and stability of the pressure relief action. One end of the handle 908 is fixedly connected to one end of the threaded rod 904, allowing the operator to easily rotate the threaded rod 904 by turning the handle 908, thereby adjusting the position of the pressure regulating plate 905, changing the compression of the spring 909, and adjusting the pressure relief value. A limit plate 907 is installed on the other end of the threaded rod 904 to prevent the pressure regulating plate 905 from going out of the normal adjustment range due to excessive rotation of the threaded rod 904.

[0031] Please see Figures 1-5 Both sides of the pressure regulating plate 905 are equipped with sliders 910. A pair of grooves 911 are opened on the inner side of the pressure relief pipe 901. The outer side of the slider 910 and the inner side of the groove 911 are slidably connected. Valves 7 are installed on the other end face of the storage tank body 1 and the other end face of the pressure relief tank 6. A pressure sensor is installed inside the storage tank body 1. A control panel 10 is installed on the other side of one of the support frames 2. The sliding connection between the outer side of the slider 910 and the inner side of the groove 911 improves the movement stability of the pressure regulating plate 905. The valves 7 installed on the other end face of the storage tank body 1 and the other end face of the pressure relief tank 6 can control the entry and exit of the medium in the storage tank body 1 and the pressure relief tank 6 respectively. The pressure sensor installed inside the storage tank body 1 can monitor the pressure data inside the storage tank in real time and transmit the data to the control panel 10 on one side of the support frame 2.

[0032] Working principle

[0033] In use, the storage tank body 1 is used to store the medium. The support frame 2 and the fixed base 3 cooperate to provide stable support for the storage tank body 1, ensuring that the storage tank remains stable during use. The side frame 4 and the retaining frame 5 are used to install the pressure relief tank 6, providing a support structure for the pressure relief system. The pressure relief pipe 901, the conical plug 903, and the exhaust pipe 902 in the pressure relief mechanism 9 form a pressure relief channel. When the internal pressure of the storage tank body 1 exceeds the set value, the pressure pushes the conical plug 903 to overcome the elastic force of the spring 909, causing the exhaust port 801 to open and release the gas. The pressure is discharged into the pressure relief tank 6 through the exhaust pipe 902 to achieve safe pressure relief and prevent the storage tank from exploding due to excessive pressure. The threaded rod 904 and the pressure regulating plate 905 can adjust the compression degree of the spring 909, thereby changing the pressure relief threshold to meet the pressure relief requirements under different storage media and operating conditions. Several sliding rods 906 are slidably connected to the inner side of the pressure regulating plate 905 to guide the movement of the conical plug 903, ensuring that the conical plug 903 can slide smoothly along the sliding rods 906 during the pressure relief process, preventing deviation or jamming, and ensuring pressure relief. The reliability and stability of the operation are ensured by a fixed connection between one end of the throttle 908 and one end of the threaded rod 904. This allows the operator to easily rotate the threaded rod 904 by turning the throttle 908, thereby adjusting the position of the pressure regulating plate 905, changing the compression of the spring 909, and adjusting the pressure relief value. A limit plate 907 is installed at the other end of the threaded rod 904 to prevent excessive rotation of the threaded rod 904 from causing the pressure regulating plate 905 to move out of its normal adjustment range. The sliding connection between the outer side of the slider 910 and the inner side of the slide groove 911 improves the stability of the pressure regulating plate 905's movement. Valves 7 are installed on the other end faces of both the storage tank body 1 and the pressure relief tank 6, allowing for the control of the inflow and outflow of the medium in the storage tank body 1 and the pressure relief tank 6, respectively. A pressure sensor is installed inside the storage tank body 1, enabling real-time monitoring of the pressure data inside the tank and transmitting the data to the control panel 10 on one side of the support frame 2. This invention effectively provides pressure relief and regulation functions, meeting the safety requirements of modern industry for storage tanks and possessing high practical value.

[0034] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Based on the technical solution of the present utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the present utility model.
