Description

Technical Field

[0001] The utility model relates to the technical field of storage tanks, in particular to a liquid nitrogen and liquid oxygen storage tank. Background Art

[0002] As important industrial gases, liquid nitrogen and liquid oxygen are widely used in the fields of medical treatment, scientific research, and chemical industry. However, due to their extremely low temperature and high chemical activity, the storage and transportation of liquid nitrogen and liquid oxygen require special care and professional equipment. Among them, liquid nitrogen and liquid oxygen storage tanks are key equipment for storing these gases. In the current liquid nitrogen and liquid oxygen storage technology, although the design of the tank's sealing, thermal insulation, and safety valve is quite mature, there are obvious deficiencies in anti-collision.

[0003] The Chinese patent discloses: a new type of liquid nitrogen and liquid oxygen storage tank, patent application number: 202121632202.X, which "includes a main tank body and an inner tank, the inner tank is arranged inside the main tank body, a vacuum layer is provided between the inner tank and the main tank body, a polyisocyanurate foam layer is provided in the vacuum layer, a feed pipe is connected between the top of the main tank body and the inner tank, a first plug is fixedly inserted at the top of the feed pipe, an injection pipe is connected between one side of the main tank body and the inner tank, a second plug is inserted in the injection pipe, an exhaust pipe is connected between the end of the main tank body away from the injection pipe and the inner tank, a safety valve is provided on the exhaust pipe, and a discharge pipe is connected between the bottom of the inner tank and the main tank body".

[0004] Although the device can be used for insulation needs of various storage tanks, equipment, and buildings by injecting polyurea into the vacuum layer, the device does not have a protective structure, which causes liquid nitrogen and liquid oxygen storage tanks to often ignore the potential impact of the external environment on the tank body, especially the risk of impact. In actual application scenarios, liquid nitrogen and liquid oxygen storage tanks may be hit due to handling, transportation, or changes in the surrounding environment. These impacts may not only cause damage to the tank body, but more seriously, may cause leakage of liquid nitrogen or liquid oxygen, resulting in serious consequences such as personal injury, environmental pollution, and even fire. At the same time, compared with the existing protective structure, the entire protective structure needs to be replaced after a collision, which wastes materials and is inconvenient to use. Utility Model Content

[0005] In view of this, the purpose of the utility model is to propose a liquid nitrogen and liquid oxygen storage tank to solve the problem that the liquid nitrogen and liquid oxygen storage tank may be subjected to impact due to handling, transportation or changes in the surrounding environment.

[0025] like Figures 1 to 4 As shown, a liquid nitrogen and liquid oxygen storage tank comprises a storage tank body 1, a fixing ring 2 is fixedly connected to the top and bottom of the outer wall of the storage tank body 1, a fixing strip 3 is fixedly connected between the fixing rings 2, a honeycomb protection strip 4 is fixedly connected to the side of the fixing strip 3 close to the storage tank body 1, and the shape of the honeycomb protection strip 4 is wavy, a plurality of equidistant and uniform outer cylinders 5 are fixedly connected to the outer wall of the storage tank body 1, a telescopic spring 6 is fixedly connected to the inside of the outer cylinder 5, one end of the telescopic spring 6 is fixedly connected to the inner cylinder 7, the inner cylinder 7 is slidably connected to the inside of the outer cylinder 5, and one end of the inner cylinder 7 is fixedly connected to the honeycomb protection strip On the side wall of the strip 4, a polyurethane elastomer material 8 is fixedly connected to the side of the honeycomb protection strip 4 close to the fixed strip 3, and a plurality of equidistant and uniform protective sleeves 9 are fixedly connected to the side of the fixed strip 3 away from the honeycomb protection strip 4. The interior of the protective sleeve 9 is a sealed environment, and the interior of the protective sleeve 9 is filled with foam balls 10. The outer walls of the protective sleeve 9 are both placed with protective shells 11. The shapes of the protective sleeves 9 and the protective shells 11 are arc-shaped. Through the shapes of the protective shells 11 and the protective sleeves 9, the protective ability of the protective sleeves 9 is improved. The two sides of the protective sleeve 9 are fixedly connected with replacement mechanisms for replacing the protective shells 11.

[0026] When there is an external force impact, it will first contact the protective shell 11, and then the protective shell 11 will be recessed and transfer the impact force to the protective sleeve 9, and then the sealed environment inside the protective sleeve 9 and the foam ball 10 inside the protective sleeve 9 can effectively buffer the impact force. After buffering, a part of the force will still be transferred to the fixing strip 3, and then the fixing strip 3 will be recessed on one side of the storage tank body 1 and squeeze the polyurethane elastomer material 8 and the honeycomb protective strip 4, and then the shape of the polyurethane elastomer material 8 and the honeycomb protective strip 4 will further buffer the collision force, so that it can be applied to the storage tank body 1. For protection, the honeycomb protection strip 4 will then be recessed toward one side of the storage tank body 1 and squeeze the inner tube 7, and the inner tube 7 will slide in the outer tube 5 and squeeze the telescopic spring 6. The telescopic spring 6 can further buffer the collision force to protect the storage tank body 1. At the same time, the honeycomb protection strip 4 is supported by the outer tube 5 and the inner tube 7 to make its overall structure more firm and reliable, effectively protecting the storage tank body 1, avoiding the impact force from colliding with the storage tank body 1, causing damage to the storage tank body 1 and leakage during use, while also avoiding personal injury and environmental pollution, making it easy to use.

At this time, the two sides of the block 18 will squeeze one end of the slider 16, and then the slider 16 will shrink back into the slide groove 14 and squeeze the spring 15, and then continue to pull the pull ring 19, so that the block 18 can be pulled out of the slot 13, so that the protective shell 11 can be taken out and replaced with a new protective shell 11, without the need to replace the entire protective shell 11, thereby avoiding the waste of protective materials, reducing economic expenses, and facilitating use.

[0029] For further information, see Attachment Figure 2As shown, the honeycomb protection strip 4, the protection cover 9 and the protection shell 11 are all made of flexible materials. By being made of flexible materials, they can transmit force step by step and provide buffering protection step by step, thereby avoiding damage to the honeycomb protection strip 4, the fixing strip 3, the protection cover 9 and the protection shell 11.
