Description

Technical Field

[0001] The invention belongs to the technical field of storage tank pressure protection, and in particular relates to a storage tank pressure protection device. Background Art

[0002] A storage tank is a large container used to store liquids or gases, usually made of metal (such as steel) or concrete to ensure safety and durability. They are widely used in various industrial fields such as petrochemicals, food processing, pharmaceuticals, water treatment, fertilizer production, and oil and gas storage in the energy industry. The design of a storage tank usually takes into account the characteristics of the stored material, such as pressure, temperature, chemical properties, etc., as well as environmental conditions such as wind loads, seismic forces, etc. Storage tanks can be above-ground or underground, and can be designed to be fixed or mobile to meet different usage requirements. In industrial production and energy supply, storage tanks play a key role, ensuring the safe storage and supply of raw materials and products.

[0003] Storage tanks are generally filled with gas or liquid. When a storage tank is filled with gas, its volume will change with temperature. When the temperature rises, the volume of the gas will increase, thereby increasing the pressure in the tank. When liquid is stored in the tank, after the liquid is affected by the environment or remains stationary for a long time, a layer of vapor will appear above the surface of the tank, causing the internal pressure to increase. The substances in the tank may react or undergo chemical changes, releasing gas, causing the pressure in the tank to increase, thereby greatly increasing the potential safety hazards of the tank. Existing tank pressure protection devices mostly use gas exhaust to achieve pressure relief during pressure relief work. When gas containing other substances is generated in the tank and discharged out of the device, it is easy to cause air deterioration, thereby increasing environmental pollution problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a storage tank pressure protection device.

[0005] The technical solution adopted to solve the above technical problems is: to provide a storage tank pressure protection device, including a main body, a base is fixedly connected to the bottom of the main body, a feed port is opened on one side of the top of the main body, a fixing ring is fixedly connected to the outer wall of the main body, and a pressure relief barrel is fixedly connected to the inner wall of one side of the fixing ring;

[0006] A safety valve mechanism is installed at the middle end of the top of the main body, one side of the safety valve mechanism is fixedly connected to the first gas pipeline, and a pressure relief mechanism is installed inside the pressure relief barrel;

[0007] A cooling mechanism is installed inside the pressure relief barrel, an adjusting mechanism is installed on the top of the cooling mechanism, a plurality of exhaust holes are opened on the outer wall of the pressure relief barrel, a second air supply pipe is fixedly connected to the bottom of the pressure relief barrel, and a one-way valve is provided on the outer wall of the second air supply pipe.

[0008] Furthermore, the safety valve mechanism includes a protection tube fixedly connected to the top of the main body, a first T-tube fixedly connected inside the protection tube, a sealing valve movably connected to the top of the first T-tube, a connecting sleeve fixedly connected inside the protection tube, a guide rod fixedly connected to the top of the connecting sleeve, a spring is provided at the top of the sealing valve, an outer wall of the spring is provided with an outer shell, the first T-tube is connected to the top of the main body, the outer wall of the sealing valve is movably connected to the connecting sleeve, and the guide rod passes through the top of the outer shell.

[0009] Through the above technical scheme, when in use, after the operator puts the material into the storage tank through the feed port, the material in the storage tank will undergo a series of changes over time. After changes in the environment and the interior, the internal pressure increases. When the pressure inside the storage tank is large enough, the internal gas is then discharged to the outside through the safety valve mechanism, thereby reducing the internal pressure, ensuring the safety inside the storage tank, and reducing safety hazards. Specifically, when the pressure inside the storage tank is large enough, the gas will push the sealing valve upward from the first T-tube inside the protective tube, and then the sealing valve will slide upward in the connecting sleeve, thereby compressing the spring to achieve gas discharge, and then the gas will be discharged from the first gas pipe, thereby reducing the internal pressure of the storage tank and protecting the safety inside the storage tank.

[0010] Furthermore, the pressure relief mechanism includes a motor fixedly connected to the bottom of the pressure relief barrel, the output end of the motor is fixedly connected to a drive shaft, the outer wall of the drive shaft is fixedly connected to two first baffles, the outer wall of the drive shaft is fixedly connected to a second baffle, and the first baffle and the second baffle are both located inside the pressure relief barrel.

[0011] Through the above technical scheme, when in use, when different substances are stored in the storage tank, the gas generated will have different impacts on the environment. When the gas has no other impurities, it can be adjusted through the pressure relief mechanism, and the gas will be directly discharged from multiple exhaust holes through the pressure relief barrel. When the gas has other impurities, the gas is processed by the pressure relief mechanism to reduce the impact of the gas on the environment, and the gas can be processed in the presence of other impurities to achieve protection of the internal pressure of the storage tank. Specifically, when the gas is non-toxic, the gas enters the pressure relief barrel through the first gas pipe. At this time, the motor at the bottom of the pressure relief barrel is started to drive the drive shaft to rotate, and then the two first baffles rotate the position of the exhaust hole, and the second baffle blocks the connection between the pressure relief barrel and the second gas pipe, thereby achieving the discharge of non-toxic gas. When the gas has other impurities, repeat the above steps until the connection between the pressure relief barrel and the second gas pipe is released, and multiple exhaust holes are blocked, thereby achieving environmental protection and ensuring that the gas containing impurities can proceed to the next step.

[0012] Furthermore, the cooling mechanism includes a cooling tube fixedly connected to the inner wall of the pressure relief barrel, the outer wall of the cooling tube is rotatably connected to a collecting pipe, the cooling tube wall is provided with a plurality of sealing rings, the inner walls of the plurality of sealing rings are rotatably connected to a second T-tube, the top of the inner wall of the cooling tube is fixedly connected to a fan-shaped connecting block, the outer wall of the fan-shaped connecting block is fixedly connected to a T-block, the top of the cooling tube is fixedly connected to a backflow pipe, the bottom of the inner wall of the cooling tube is fixedly connected to a fine hole, the outer wall of the collecting pipe is provided with an air inlet hole, the bottom of the cooling tube is connected to the second gas supply pipe, the diameter of the T-block is larger at the top and smaller at the bottom, and the diameter of the second T-tube is larger at the outside and smaller at the inside.

[0013] By using the above technical scheme, when impurity gas enters the pressure relief barrel through the safety valve mechanism, as the interior of the storage tank and the environment change, the temperature reduction mechanism is used to process the impurity gas, so that the gas can shrink to a certain volume under the same pressure, thereby reducing the pressure, and the pressure in the storage tank will be reduced, thereby protecting the interior of the storage tank. Specifically, as the interior of the storage tank changes, the gas enters the pressure relief barrel and is full, and the gas will enter the interior from the air inlet hole on the outer wall of the manifold, and then enter from the second T-tube. When the gas passes through pipes with different diameters at both ends, the gas flow rate increases and the gas temperature decreases. According to the gas state equation (PV = nRT), under the same pressure, the volume of the gas will decrease, thereby increasing the density, which means that in the same volume, the number of gas molecules increases, that is, the average distance between molecules decreases, thereby achieving pressure reduction. When the gas enters the cooling pipe, the gas will move in the pipe in a circular flow to separate. When the gas collides with the T-block, the external hot air flow will be discharged from the gap of the T-block, and can return to the first gas pipeline with the cooperation of the backflow pipe and the single valve on its outer wall. With the collision, the internal cold air flow will be discharged from the middle of the pipe through the fine hole through the second gas pipeline. With the cooperation of the one-way valve, the gas will return to the storage tank, so that the internal pressure can be reduced by repeating the cycle, thereby achieving internal pressure reduction and protecting the storage tank.

[0014] Furthermore, the adjustment mechanism includes a rotating screw block rotatably connected to the top of the pressure relief barrel, a plurality of connecting columns are fixedly connected to the bottom of the rotating screw block, a plurality of steering connecting rings are rotatably connected inside the collecting pipe, chains are fixedly connected between the plurality of second T-tubes, the bottoms of the plurality of connecting columns are fixedly connected to the collecting pipe, and the plurality of steering connecting rings are rotatably connected to the corresponding second T-tubes.

[0015] Through the above technical solution, when in use, when the exhaust gas is in the process of just entering or being filled in the pressure relief barrel, the gas can be protected from the cooling tube through the regulating mechanism, thereby extending the service life. Specifically, when the gas just enters, the gas will slowly enter from the second T-tube. At this time, the operator can drive the collecting pipes at the bottom of multiple connecting columns to rotate by rotating the rotating screw block. Under the connection of multiple steering connecting rings and chains, as the rotating screw block rotates, the second T-tube is gradually deflected. At this time, the airflow passing through the second T-tube will form a certain angle with the inner wall of the cooling tube. When the second T-tube is more inclined, the angle of airflow entry increases, and then the second T-tube sends gas in at a gradually increasing angle, and gradually increases the angle of gas entry and the cooling tube. When the angle of gas entry is 90 degrees to the inside of the pipeline, the number of gas and internal circulation is the largest, the gas cools down the fastest, and the loss inside the pipeline is the largest. By gradually increasing the angle of gas deflection, the loss of gas to the inner wall of the pipeline is minimized to protect the equipment. Internal adjustment and pipeline wear can be achieved through adjustment, thereby greatly improving the service life of the equipment.

[0016] The beneficial effects of the present invention are as follows: (1) The present invention can release pressure when the internal pressure of the storage tank is generated during fermentation or environmental changes by designing a safety valve mechanism, a pressure relief mechanism, a cooling mechanism and an adjusting mechanism, and the pressure relief mode can be converted under different circumstances, thereby increasing the application capacity of the storage tank. At the same time, the internal part can be protected accordingly during the pressure relief process, thereby greatly enhancing the service life of the protection device; (2) The present invention can release pressure through the safety valve mechanism when the internal pressure of the storage tank increases by designing a safety valve mechanism and a pressure relief mechanism, thereby reducing the safety operation of the storage tank, and the gas generated by the substances stored in the storage tank can be treated in different ways, thereby greatly enhancing the applicability of the storage tank; (3) The present invention can reduce the temperature of the internal gas under the same pressure when the gas generated inside the storage tank contains other substances, thereby reducing the volume of the internal gas as much as possible, thereby reducing the pressure, achieving non-exhaustion of gas, protecting the environment, and at the same time, in the process of gas cooling, as the degree of cooling increases, damage to the pipeline will be caused by the control of the adjusting mechanism, thereby protecting the device and extending the service life.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] like Figure 1-Figure 10As shown, a storage tank pressure protection device of this embodiment includes a main body 1, a base 2 is fixedly connected to the bottom of the main body 1, a feed port 3 is opened on one side of the top of the main body 1, a fixing ring 4 is fixedly connected to the outer wall of the main body 1, a pressure-relief barrel 5 is fixedly connected to the inner wall of one side of the fixing ring 4, a safety valve mechanism 6 is installed at the middle end of the top of the main body 1, the safety valve mechanism 6 includes a protection tube 601 fixedly connected to the top of the main body 1, a first T-tube 602 is fixedly connected inside the protection tube 601, a sealing valve 603 is movably connected to the top of the first T-tube 602, a connecting sleeve 604 is fixedly connected inside the protection tube 601, a guide rod 605 is fixedly connected to the top of the connecting sleeve 604, a spring 606 is provided at the top of the sealing valve 603, and a shell 607 is provided on the outer wall of the spring 606, the first T-tube 602 is connected to the top of the main body 1, and the outer wall of the sealing valve 603 is movably connected to the connecting sleeve 604 Dynamic connection, the guide rod 605 passes through the top of the shell 607. When in use, after the operator puts the material into the storage tank through the feed port 3, the material in the storage tank will undergo a series of changes over time. After changes in the environment and the interior, the internal pressure increases. When the pressure inside the storage tank is large enough, the internal gas is then discharged to the outside through the safety valve mechanism 6, thereby reducing the internal pressure, ensuring the safety inside the storage tank, and reducing safety hazards. Specifically, when the pressure inside the storage tank is large enough, the gas will push the sealing valve 603 upward from the first T-tube 602 inside the protection tube 601, and then the sealing valve 603 will slide upward in the connecting sleeve 604, thereby compressing the spring 606 to achieve gas discharge, and then the gas will be discharged from the first gas pipe 7, thereby reducing the internal pressure of the storage tank and protecting the safety inside the storage tank.

[0030] like Figure 7As shown, a first gas pipe 7 is fixedly connected to one side of the safety valve mechanism 6, and a pressure relief mechanism 8 is installed inside the pressure relief barrel 5. The pressure relief mechanism 8 includes a motor 801 fixedly connected to the bottom of the pressure relief barrel 5, and a driving shaft 802 is fixedly connected to the output end of the motor 801. Two first baffles 803 are fixedly connected to the outer wall of the driving shaft 802, and a second baffle 804 is fixedly connected to the outer wall of the driving shaft 802. The first baffle 803 and the second baffle 804 are both located inside the pressure relief barrel 5. When in use, when different substances are stored in the storage tank, the gas generated will have different impacts on the environment. When the gas has no other impurities, it can be adjusted through the pressure relief mechanism 8, and the gas will be directly discharged from multiple exhaust holes 11 through the pressure relief barrel 5. When the gas has other impurities, the gas is processed through the pressure relief mechanism 8. , thereby reducing the impact of gas on the environment, and being able to process gas in the presence of other impurities, to protect the internal pressure of the storage tank. Specifically, when the gas is non-toxic, the gas enters the pressure-relief barrel 5 through the first gas pipe 7. At this time, start the motor 801 at the bottom of the pressure-relief barrel 5 to drive the drive shaft 802 to rotate, and then the two first baffles 803 turn the position of the exhaust hole 11 out, and at the same time, the second baffle 804 blocks the connection between the pressure-relief barrel 5 and the second gas pipe 12, thereby realizing the discharge of non-toxic gas. When the gas contains other impurities, repeat the above steps until the connection between the pressure-relief barrel 5 and the second gas pipe 12 is released, and at the same time, multiple exhaust holes 11 are blocked, thereby realizing environmental protection and ensuring that the gas containing impurities can proceed to the next step.

[0031] like Figure 8-Figure 10As shown, a cooling mechanism 9 is installed inside the pressure-reducing barrel 5, and the cooling mechanism 9 includes a cooling tube 901 fixedly connected to the inner wall of the pressure-reducing barrel 5, and the outer wall of the cooling tube 901 is rotatably connected to a collecting pipe 902, and the wall of the cooling tube 901 is provided with a plurality of sealing rings 903, and the inner walls of the plurality of sealing rings 903 are rotatably connected to a second T-shaped tube 904, and the top of the inner wall of the cooling tube 901 is fixedly connected to a fan-shaped connecting block 905, and the outer wall of the fan-shaped connecting block 905 is fixedly connected to a T-shaped block 906, and the top of the cooling tube 901 is fixedly connected to a backflow pipe 907, and the bottom of the inner wall of the cooling tube 901 is fixedly connected to a fine hole 908, and the outer wall of the collecting pipe 902 is provided with an air inlet hole, and the bottom of the cooling tube 901 is connected to the second gas pipeline 12, and the diameter of the T-shaped block 906 is larger at the top and lower at the bottom. The second T-tube 904 has a large outer diameter and a small inner diameter. When in use, after impurity gas passes through the safety valve mechanism 6 and enters the pressure-relief barrel 5, as the interior of the storage tank and the environment change, the cooling mechanism 9 is used to process the impurity gas. Under the same pressure, the gas can be reduced in volume to achieve pressure reduction. The pressure in the storage tank will be reduced, thereby protecting the interior of the storage tank. Specifically, as the interior of the storage tank changes, the gas enters the pressure-relief barrel 5 and is full. At this time, the gas will enter the interior from the air inlet hole on the outer wall of the manifold 902, and then enter from the second T-tube 904. When the gas passes through pipes with different diameters at both ends, the gas flow rate increases and the gas temperature decreases. According to the gas state equation (PV = nRT), under the same pressure, the volume of the gas will decrease, thereby increasing the density, which means that within the same volume, the number of gas molecules increases, that is, the average distance between molecules decreases, thereby achieving pressure reduction. When the gas enters the cooling pipe 901, the gas will move in the pipe in a circular manner for separation. When the gas collides with the T-block 906, the external hot air flow will be discharged from the gap of the T-block 906, and can return to the first gas pipe 7 with the cooperation of the backflow pipe 907 and the single valve on its outer wall. With the collision, the internal cold air flow will be discharged from the middle of the pipe through the fine hole 908 through the second gas pipe 12. With the cooperation of the one-way valve 13, the gas will return to the storage tank, and the internal pressure will be reduced by repeating this cycle, thereby achieving internal pressure reduction and protecting the storage tank.

[0032] like Figure 6 and Figure 8As shown, an adjusting mechanism 10 is installed on the top of the cooling mechanism 9, a plurality of exhaust holes 11 are opened on the outer wall of the pressure-relief barrel 5, a second gas supply pipe 12 is fixedly connected to the bottom of the pressure-relief barrel 5, and a one-way valve 13 is arranged on the outer wall of the second gas supply pipe 12. The adjusting mechanism 10 comprises a rotating screw block 1001 rotatably connected to the top of the pressure-relief barrel 5, a plurality of connecting columns 1002 are fixedly connected to the bottom of the rotating screw block 1001, a plurality of steering connecting rings 1003 are rotatably connected inside the collecting pipe 902, a plurality of second T-tubes 904 are fixedly connected with chains 1004, a plurality of connecting columns 1002 are fixedly connected to the collecting pipe 902 at the bottom, and a plurality of steering connecting rings 1003 are rotatably connected to the corresponding second T-tubes 904 respectively. When in use, when the exhaust gas is in the process of just entering or being filled in the pressure-relief barrel 5, the adjusting mechanism 10 can protect the cooling pipe 901 for the gas, thereby extending the service life. Specifically, when the gas just enters, the gas will slowly enter from the second T-tube 904. At this time, The operator can rotate the rotating screw block 1001 to drive the collecting pipe 902 at the bottom of the multiple connecting columns 1002 to rotate. Under the connection of the multiple steering connecting rings 1003 and the chain 1004, as the rotating screw block 1001 rotates, the second T-tube 904 is gradually deflected. At this time, the airflow passing through the second T-tube 904 will form a certain angle with the inner wall of the cooling tube 901. When the second T-tube 904 is more inclined, the angle of the airflow entering increases accordingly, and then the second T-tube 904 sends the gas in at a gradually increasing angle, and gradually increases the angle of the gas entering the cooling tube 901. When the angle of the gas entering is 90 degrees with the inside of the pipeline, the number of gas and internal circulation is the largest, the gas cools down the fastest, and the loss with the inside of the pipeline is the largest. By gradually increasing the angle of the gas deflection, the loss of the gas to the inner wall of the pipeline is minimized to protect the equipment. The internal adjustment and the wear of the pipeline can be achieved through adjustment, thereby greatly improving the service life of the equipment.

[0033] The working principle of this embodiment is as follows. When in use, when the pressure inside the storage tank is large enough, the gas will push the sealing valve 603 upward from the first T-tube 602 inside the protective tube 601, and then the sealing valve 603 will slide upward in the connecting sleeve 604, thereby compressing the spring 606 to achieve gas discharge. When the gas is non-toxic, the gas enters the pressure-relief barrel 5 through the first gas transmission pipe 7. At this time, start the motor 801 at the bottom of the pressure-relief barrel 5 to drive the drive shaft 802 to rotate, and then the two first baffles 803 rotate the position of the exhaust hole 11. When the gas has no other impurities, it can be directly discharged from the multiple exhaust holes 11 through the pressure-relief barrel 5. When the gas has other impurities, as the internal part of the storage tank changes, the gas enters the pressure-relief barrel 5 and is full. At this time, the gas will be discharged from the inlet of the outer wall of the collecting pipe 902. The gas enters the interior through the air hole and then enters from the second T-tube 904. At this time, the operator can drive the collecting pipe 902 at the bottom of the multiple connecting columns 1002 to rotate by rotating the rotating screw block 1001. Under the connection of multiple steering connecting rings 1003 and chains 1004, the second T-tube 904 is driven to send the gas in at a gradually increasing angle. After the gas enters the cooling pipe 901, the gas will move inside the pipeline in a circular flow manner for separation. When the gas collides with the T-block 906, the external hot air flow will be discharged from the gap of the T-block 906 and return to the first gas pipeline 7 through the backflow pipe 907. With the collision, the internal cold air flow will be discharged from the middle of the pipeline from the fine hole 908 through the second gas pipeline 12 in a circular flow manner inside the hot air flow, thereby completing the working process of the entire pressure protection device.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
