Description

Technical Field

[0001] This utility model relates to the field of oxygen preparation technology, specifically to an oxygen preparation dehumidification pretreatment device. Background Technology

[0002] An oxygen concentrator is a machine that produces oxygen. Its principle is based on air separation technology. First, air is compressed at high density, then the different condensation points of the air components are used to separate the gas and liquid phases at a specific temperature, followed by further distillation to obtain the oxygen. During the oxygen supply process, oxygen concentrators often require a dehumidification system to dehumidify the oxygen and ensure its quality.

[0003] In response, Chinese utility model patent CN221156051U discloses an oxygen generator with a dehumidification mechanism, including a dehumidification box and a rotating assembly. A dehumidification chamber is fixedly connected inside the dehumidification box, and a horizontal shaft is rotatably connected inside the dehumidification box. One end of the horizontal shaft extends into the dehumidification box and is fixedly connected to a connecting plate. Multiple heating rods are fixedly connected to the side of the connecting plate away from the horizontal shaft. A motor is fixedly connected inside the dehumidification box, and a fan is fixedly connected to the output end of the motor. An air outlet pipe is fixedly connected to the top of the fan, and the top of the air outlet pipe extends into the dehumidification box. The rotating assembly is located inside the dehumidification box. This utility model uses a motor to drive a first pulley to rotate, which in turn drives a second pulley to rotate, which in turn drives a vertical shaft to rotate. The vertical shaft drives a worm gear to rotate, which in turn drives a worm wheel to rotate, which in turn drives a horizontal shaft to rotate. The horizontal shaft then drives the connecting plate and heating rods to rotate, thereby achieving the purpose of dehumidifying the oxygen in the dehumidification box.

[0004] The oxygen generation dehumidification pretreatment device requires the door to be opened during use, allowing staff to periodically clean the filter and replace the activated carbon. Staff need to reach into the dehumidification chamber to operate it, and the small interior space of the oxygen generator makes it inconvenient for staff to operate.

The suction fan 3 is connected to an external power supply. By starting the power supply of the suction fan 3, oxygen can be delivered to the dehumidification chamber 1 through the input pipe 5 and the delivery pipe 6. Simultaneously, the motor 11 is connected to an external power supply. By starting the motor 11, the connecting plate 13 and the heating rods 14 are rotated, so that the moisture in the oxygen inside the dehumidification chamber 1 can be quickly evaporated, thus dehumidifying the oxygen. Then, the oxygen can be blown to the top. With the cooperation of the filter plate 18 and the activated carbon plate 19, the moisture in the oxygen can be adsorbed and filtered, further reducing the moisture in the oxygen.
