Description

Technical Field

[0001] The utility model relates to the technical field of oxygen recovery devices, in particular to a cryogenic air separation oxygen recovery device. Background Art

[0002] As we all know, cryogenic oxygen production is a process that uses the different boiling points of oxygen, nitrogen and argon in air at low temperatures to separate them. This process can produce products such as oxygen and liquid oxygen. The oxygen is transported to users by pipeline, and the liquid oxygen enters the liquid oxygen storage tank for storage. The liquid oxygen in the storage tank is pressurized and filled into a cryogenic liquid oxygen tank truck using a liquid oxygen pump, and then transported to users by a cryogenic liquid oxygen tank truck. When the liquid oxygen tank truck transports the liquid oxygen to the user, a part of the liquid oxygen must be vaporized and pressurized before the liquid oxygen can be transported. After the liquid oxygen is transported, the low-temperature gaseous oxygen in the tank truck must be depressurized and vented to normal pressure before the next tank truck can be filled with liquid oxygen. After the liquid oxygen tank truck transports the liquid oxygen, the pressure of the gaseous oxygen is relatively high (0.8Mpa-1.5Mpa). The low-temperature oxygen in the liquid oxygen tank truck is generally depressurized and discharged into the atmosphere, which is easy to cause waste, so a recovery device is needed to recover the oxygen discharged into the atmosphere.

[0003] However, the existing cryogenic air separation oxygen recovery devices are generally directly exposed to the outside world. The outer wall of the recovery device is easily damaged by external objects, which can easily lead to the recovery device being deflated or even exploding. Utility Model Content

[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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0023] When in use, first place the device in the designated position, and then support the device through the bottom plate 1. The main body 3 is a conventional oxygen storage bottle on the market, including a bottle body, an air inlet pipe, an air outlet pipe, a pressure relief valve, a pressure gauge, a pressure sensor, a temperature sensor and other structures, which are not described in detail here. The outside of the main body 3 can be protected by the protective mechanism 4 to prevent the outer wall of the main body 3 from being damaged. When the protective frame 5 and the sealing plate 6 are used for a long time and are worn and need to be replaced, first pull the damping plate 13 hard to extend the telescopic rod 12 to separate the damping plate 13 from the slider 11. The damping plate 13 is made of rubber material and has a good damping effect, so that the staff needs to pull it hard by hand, and then push the slider 11 on the slide 10 to separate the slider 11 from the bottom plate 1, and then pull the connecting plate 7 to make the connecting plate 7 drive the sealing plate 6 to move, so that the sealing plate 6 drives the block 8 to separate from the fixed block 9, and the connecting plate 7 is separated from the bottom plate 1, and the sealing plate 6 can be removed.

The slide 10 and the slider 11 in this structure use T-slots. The dimensions of all components in this structure are not described in detail here and need to be produced according to actual conditions.
