The utility model relates to the technical field of
molecular sieve oxygen production equipment, in particular to a quick
oxygen concentration increasing device for medical
molecular sieve oxygen production equipment, which comprises a bottom plate, the device further comprises a treatment
barrel, a sealing cover and a rotating ring, the treatment
barrel is fixedly connected to the middle of the upper end of the bottom plate, the sealing cover is arranged at the upper end of the treatment
barrel, and a fixing column is fixedly connected to the middle side in the treatment barrel; the space in the treatment cylinder is divided into four independent working areas, the rotating ring is internally divided into two independent oxygen collecting areas, the two
molecular screening plates are divided into two groups to provide oxygen purification and
nitrogen exhaust and suction functions respectively, and the two
molecular screening plates are adjusted by the motor to work oppositely and continuously, so that continuous
gas supply is achieved, and the working efficiency is improved. When a certain working area exhausts and inhales, the other corresponding working area can be inflated with air in advance to improve the
internal pressure, so that the
molecular screening plate can directly enter the optimal adsorption state, the oxygen purification efficiency reaches the highest, and oxygen with qualified concentration is generated to meet the use of a patient.
