[0002] Currently, chemical, power, and oil refining process pipelines all require the addition of chemicals to treat process media or protect equipment. Adding chemicals to pipelines requires chemical storage tanks, and most current chemical storage tanks are atmospheric pressure vessels, vented to the atmosphere. Most chemicals are flammable, explosive, toxic, and have odors. Some chemicals also require dilution with diesel, gasoline, or kerosene. These storage areas are often close to each other, creating a dangerous situation.

[0003] Since the reagents are in an unstable state due to oxidation and deterioration and contact with air, nitrogen is often needed to assist in their storage. However, the existing tanks have poor pressure-bearing effects, and during the nitrogen pressure relief process, pressure relief is mostly carried out through a single passage, which is slow and difficult to release quickly, thus affecting the use of the storage tank.

[0004] Therefore, providing a pharmaceutical storage tank with safety protection is an issue worthy of study. Summary of the Invention

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] See also Figure 1-Figure 3 As shown, the utility model provides a pharmaceutical storage tank with safety protection, including a storage tank 1, a pressure cover 3 is detachably connected to the top opening of the storage tank 1, and a feed pipe with a sealing cover is provided on the pressure cover 3. After the sealing cover is opened, the material can be guided through the feed pipe, and the pressure cover 3 is connected to a nitrogen supply pipeline 5 and a nitrogen release pipeline 6. The nitrogen supply pipeline 5 assists in injecting nitrogen into the storage tank 1, and the pressure relief operation is achieved through the nitrogen release pipeline 6. The nitrogen supply pipeline 5 and the nitrogen release pipeline 6 are used to maintain a slightly positive nitrogen pressure inside the storage tank 1. Furthermore, the storage tank 1 or the pressure cover body 3 is connected to a pressure relief valve group 8, and the pressure relief valve group 8 includes a manual pressure relief valve connected to the storage tank 1 or the pressure cover body 3. The end of the manual pressure relief valve away from the storage tank 1 or the pressure cover body 3 is connected to a pressure relief pipe. After the manual pressure relief valve on the pressure relief valve group 8 is opened, the pressure relief pipe is opened, and the nitrogen inside the storage tank 1 can be directly discharged through the pressure relief valve group 8. In addition, a safety valve group 7 is connected between the storage tank 1 and / or the pressure cover body 3 and the pressure relief pipe, which can realize multi-channel pressure relief operation and have a good pressure relief effect.

[0026] When the device is in use, the sealing cover is opened and the medicine can be guided into the interior of the storage tank 1 through the feed pipe. When the medicine is stored in the storage tank 1, nitrogen can be injected into the storage tank 1 through the nitrogen supply pipeline 5. The nitrogen is mainly located above the medicine. Nitrogen is a stable inert gas that can prevent the medicine from coming into contact with oxygen in the air and forming explosive gas, thereby achieving an isolation effect on the medicine and having a good storage effect on the medicine. In the device, when the pressure inside the storage tank 1 is relatively high, auxiliary pressure relief can be achieved through the nitrogen relief pipeline 6, the safety valve group 7 and the pressure relief valve group 8. Pressure relief can be achieved through multiple channels, and pressure release can be achieved quickly, thereby achieving explosion-proof protection of the storage tank 1.

[0027] Furthermore, the safety valve group 7 can be connected between the storage tank 1 and the pressure relief pipe of the pressure relief valve group 8, and the safety valve group 7 can be used to achieve a safe pressure relief operation when the internal pressure of the storage tank 1 is relatively high; the safety valve group 7 can also be set between the pressure cover body 3 and the pressure relief pipe of the pressure relief valve group 8, and the safety valve group 7 can be used to achieve a safe pressure relief operation when the internal pressure of the storage tank 1 is relatively high.

[0028] The preferred number of safety valve groups 7 is two, which are respectively arranged between the storage tank 1 and the pressure relief pipe of the pressure relief valve group 8, and between the pressure cover body 3 and the pressure relief pipe of the pressure relief valve group 8. The two groups of safety valve groups 7 can be used in a state of one backup and one backup, so that the nitrogen pressure in the storage tank 1 maintains a constant micro-positive pressure.

[0029] In the connection structure between the pressure cover 3 and the storage tank 1, flanges are connected to both the facing surfaces of the pressure cover 3 and the storage tank 1. That is, the number of flanges is two. The two flanges are respectively welded to the pressure cover 3 and the storage tank 1. The holes on the two flanges correspond to each other and are fixedly connected through bolts passing through. And a rubber ring is provided between the two flanges. Further, a plurality of pressing members 4 corresponding to the pressure cover 3 are rotatably connected to the outer wall of the storage tank 1. The pressing members 4 are in the shape of a "C" or an inverted "L". The lower end of the pressing member 4 is rotatably connected to the storage tank 1, and the upper end of the pressing member 4 can be rotated to a state corresponding to the pressure cover 3. A pressing bolt 401 for pressing the pressure cover 3 is provided at the movable end of the pressing member 4. When the movable end of the pressing member 4 is rotated to correspond to the pressure cover 3, by screwing the pressing bolt 401, the pressure cover 3 can be pre-pressed through the bottom end of the pressing bolt 401, thereby assisting in the connection between the storage tank 1 and the pressure cover 3. Further, during the use of the storage tank 1, the pressure cover 3 can be pressed to improve the use effect of the chemical agent storage tank 1.

[0030] The surface of the pressure cover 3 is stepped. Blind holes corresponding to the pressing bolts 401 are provided on the surface of the pressure cover 3. When the pressing bolts 401 are screwed, the bottom ends of the pressing bolts 401 can extend into the blind holes, enabling the pressing of the pressure cover 3, with a better pressing effect on the pressure cover 3 and ensuring the storage effect of the storage tank 1.

[0031] A buffer layer 2 is provided on the inner wall of the storage tank 1. Further, longitudinally extending outer ribs 101 are provided on the outer wall of the storage tank 1, and cross-extending cross ribs 102 are provided on the inner wall of the storage tank 1. The outer ribs 101 and the cross ribs 102 are both welded to the storage tank 1. The buffer layer 2 is vulcanized to the inner wall of the storage tank 1. In another embodiment, the outer ribs 101 and the cross ribs 102 are integrally formed with the storage tank 1. The acute angle formed by the intersection of the cross ribs 102 is 60°. The inner wall of the storage tank 1 can be wrapped by the cross ribs 102, and the outer wall of the storage tank 1 can be wrapped by the outer ribs 101, which can enhance the overall strength of the storage tank 1. In addition, the buffer layer 2 can achieve buffering of the inner wall of the storage tank 1 and protect the inner wall of the storage tank 1, enabling the storage of corrosive materials in the storage tank 1 with a wider storage range. And during the storage of chemical agents, when the pressure on the storage tank 1 is relatively large, buffering can be achieved through the buffer layer 2, and the overall strength of the storage tank 1 can be improved through the outer ribs 101 and the cross ribs 102, enabling the storage tank 1 to withstand a certain pressure, thereby improving the storage effect of the storage tank 1 for chemical agents.

[0032] The nitrogen supply pipeline 5 includes a nitrogen supply valve and a manual ball valve connected to the gas transmission pipeline and a gas source away from the end of the pressure cover body 3; the nitrogen release pipeline 6 includes a nitrogen release valve and a manual ball valve connected to the release pipeline. When a certain amount of medicine is stored in the storage tank 1, nitrogen is filled into the top of the storage tank 1. Nitrogen can isolate the material to prevent the internal components from being oxidized, corroded, and polymerized due to the presence of oxygen, thereby reducing volatilization and waste. The nitrogen supply valve is a valve that controls the supply of nitrogen to the system. After opening the manual ball valve, When the internal pressure of the storage tank 1 is low, the nitrogen supply valve is in the open state, and the nitrogen in the gas source is filled into the interior through the nitrogen supply valve. In addition, in conjunction with the nitrogen release valve on the nitrogen release pipeline 6, the nitrogen release valve is usually in a normally closed state. When the internal pressure of the storage tank 1 is too high, that is, when the pressure exceeds the set pressure of the nitrogen release valve, the nitrogen release valve will automatically open to achieve pressure relief operation. Once the pressure is released back to a safe range, the nitrogen release valve will automatically close. The nitrogen supply valve pressure cover 3 and the nitrogen release valve pressing member 4 respectively control the pressure behind and before the valve.

[0033] Furthermore, the safety valve group 7 includes a pressure control valve and a manual ball valve connected to the pipeline. After the manual ball valve on the safety valve group 7 is opened, the safety valve group 7 as a whole is in a passage state. When the internal pressure of the storage tank 1 is too high, the pressure relief effect of the nitrogen relief valve on the nitrogen relief pipeline 6 alone is weak. At this time, the pressure control valve on the safety valve group 7 is activated, which can achieve a synchronous pressure relief operation, further relieving the pressure inside the storage tank 1, ensuring that the pressure of the system is stable within a certain range, and maintaining a closed environment. In a preferred embodiment, the number of safety valve groups 7 is two, thereby ensuring the stability of the pressure inside the storage tank 1;

[0034] In a preferred embodiment, a sensor module for detecting the internal pressure of the storage tank 1 is provided on the inner side of the pressure cover body 3. The sensor module includes an air pressure detection sensor and a controller. The nitrogen supply valve, nitrogen release valve, sensor module, and pressure control valve are all electrically connected to the controller. The electronically controlled valves in the device can be directly controlled by the control device, and the corresponding data can be recorded.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
