Description

Technical Field

[0001] The utility model relates to the technical field of molecular sieve oxygen production equipment, in particular to a device for rapidly increasing the oxygen concentration of medical molecular sieve oxygen production equipment. Background Art

[0002] A molecular sieve oxygen concentrator is a device that separates and purifies oxygen in the air. The main components of the air are nitrogen and oxygen, of which the nitrogen content is about 17% to 18% and the oxygen content is about 71%. The working principle of the molecular sieve oxygen concentrator is to capture nitrogen through molecular sieve pressure swing adsorption, blocking nitrogen with relatively larger molecular volume, while allowing oxygen with relatively smaller molecules to pass through. After the oxygen is collected, the concentration is greatly increased and can be provided to patients for breathing.

[0003] In practice, pressure is an important factor affecting the adsorption of nitrogen by molecular sieves. The greater the pressure, the stronger the adsorption and the higher the oxygen concentration obtained. However, when the nitrogen adsorbed on the surface of the molecular sieve reaches a certain amount, it is not conducive to the passage of oxygen through the screening. Therefore, it is necessary to reduce the pressure and exhaust the air to remove the nitrogen adsorbed on the surface of the molecular sieve. Therefore, the existing medical molecular sieve oxygen production equipment generally consists of two adsorption towers that perform the same cycle process respectively, thereby achieving continuous gas supply. However, when the two sets of equipment switch working states, since one set of molecular sieves has just completed pressure reduction and exhaust, if air is connected for oxygen purification, the internal pressure is low at this time, which affects the adsorption capacity of the molecular sieve, thereby affecting the rapid extraction of oxygen concentration. The oxygen concentration is unqualified, and the oxygen extracted during this period is not conducive to patient inhalation. Too low a concentration may even affect the patient's first aid.

[0004] Therefore, in view of the above-mentioned existing medical molecular sieve oxygen production equipment, the two sets of circulation equipment have the problem of low extracted oxygen concentration due to too low pressure when switching work, which is not conducive to the rapid purification of oxygen, thereby producing unqualified oxygen and affecting the rescued patients. A medical molecular sieve oxygen production equipment oxygen concentration rapid improvement device can be designed. By dividing the processing cylinder and the rotating ring into two groups of two molecular screening plates to provide space for oxygen purification and nitrogen exhaust and suction respectively, the operation of the two molecular screening plates is adjusted by a motor to achieve continuous gas supply. When a certain working area is being exhausted, the corresponding other working area can be filled with air in advance to increase the internal pressure, which is conducive to the molecular screening plate directly entering the optimized adsorption state, the efficiency of oxygen purification is maximized, and oxygen with a qualified concentration is produced to meet the patient's use. Utility Model Content
