Abstract
Description
Technical Field
[0001] This utility model relates to the field of oxygen filling technology, and in particular to a liquefied pressurization device for oxygen filling. Background Technology
[0002] An oxygen filling, liquefaction, and pressurization device is a device used to liquefy and pressurize oxygen and fill it into a special storage container (such as an oxygen cylinder or Dewar flask). The device uses cryogenic liquefaction technology and a pressurization system to convert gaseous oxygen into liquid oxygen and ensures that it is kept under high pressure during storage and transportation to meet the demand for high-purity liquid oxygen in industries, medical fields, scientific research, and other fields.
[0003] During the oxygen filling and liquefaction process, the system involves multiple high-pressure connection points, valves, welds, and sealing interfaces. Any minor leak can not only lead to oxygen loss and reduce filling efficiency, but may also increase the risk of combustion and explosion due to oxygen accumulation. However, oxygen itself is a colorless and odorless gas, and it is difficult to detect leaks directly through the senses under normal conditions. Traditional detection methods such as olfactory judgment and pressure gauge monitoring often cannot achieve rapid and accurate location, especially in complex pipelines and joints, where the efficiency of leak point investigation is low and the maintenance cost is high. Utility Model Content

[0005] This utility model provides a liquefied pressurization device for oxygen filling, comprising two mounting rings and an oxygen tank. The two mounting rings are symmetrically arranged left and right and connected by bolts. The outer side of the oxygen tank is fitted against the inner sidewall of the mounting rings. Two vertical plates are fixedly connected to the top of each of the two mounting rings. Each pair of adjacent vertical plates is symmetrically arranged front and back. A fixing plate is fixedly connected to the corresponding side of the two left-side vertical plates. A welding plate is fixedly connected between the two fixing plates. A mounting plate is fixedly connected to the top of each of the two fixing plates. A motor is fixedly connected between the two mounting plates. A movable gear is fixedly connected to the motor's power output shaft. A mounting bearing is fixedly connected to the bottom of the welding plate. The bearing is fixedly connected to a ring gear at the bottom. The ring gear is sleeved on the outside of the oxygen tank near the top. A moving rod is fixedly connected to the bottom of the ring gear near the right side. A linkage block is fixedly sleeved on the outside of the moving rod. A brush is provided on the left side of the linkage block. The moving gear meshes with the ring gear on the outside. The limiting frame has a lifting plate in its inner cavity. A base block is fixedly connected to the bottom of the lifting plate. Moving rods are provided through the front and rear sides of the base block.
