Efficient-purification low-energy-consumption industrial oxygen generator

The invention discloses an efficient-purification low-energy-consumption industrial oxygen generator, and relates to the technical field of oxygen generators. The efficient-purification low-energy-consumption industrial oxygen generator comprises a main body, wherein adsorption towers are arranged at four corners in the main body, and a fixing ring is fixedly arranged above the four sets of adsorption towers in the main body. According to the invention, a roller drives a matching frame and a bottom cylinder to move downwards by a certain distance under the action of a convex block, a communicating pipe of an adsorption tower corresponding to the roller passively extends into the bottom cylinder and at the moment, the structure is arranged above each set of adsorption tower, high-pressure gas can be introduced into one set of corresponding adsorption tower for oxygen production every time the rotating ring and the convex block rotate by 90 degrees, while high-pressure gas is introduced into one set of adsorpti
