Description

Technical Field

[0001] The utility model relates to the technical field of oxygen supply equipment, in particular to an oxygen supply equipment for preparing and filling oxygen. Background Art

[0002] Air filter is a device that captures dust from gas-solid two-phase flow and purifies the gas through the action of porous filter materials. It sends the low-dust air into the room after purification to ensure the process requirements of the clean room and the air cleanliness in the general air-conditioned room.

[0003] After searching, the Chinese patent publication number CN212403464U discloses an oxygen supply device for oxygen production, including a compressor, an air filter, a plurality of molecular sieves, an oxygen buffer tank, a fine filter, a gas booster module, an oxygen cylinder and a control component; the outlet of the compressor is connected to the air filter through a pipeline, and the air filter is used to filter impurities such as oil, dust, and water vapor in the air, so as to output clean air, and the outlet of the air filter is provided with an air path switching valve, and the air path switching valve has a plurality of outlets, and each outlet of the air path switching valve is connected to a molecular sieve, and the molecular sieve is connected to each outlet of the molecular sieve. The sub-sieve is used to separate oxygen from the air. The outlets of multiple molecular sieves are all connected to the oxygen buffer tank. The separated oxygen enters the oxygen buffer tank. The outlet of the oxygen buffer tank is connected to the fine filter. The fine filter filters the oxygen in the oxygen buffer tank again to remove impurities such as water vapor and particles in the oxygen. The outlet of the fine filter is connected to the gas booster module. The oxygen that has been filtered again enters the oxygen cylinder after being boosted by the gas booster module, that is, the oxygen filling of the oxygen cylinder is completed. The outlet of the gas booster module is connected to the oxygen cylinder, and the gas circuit switching valve and the gas booster module are both electrically connected to the control component. The above patent has the following shortcomings: Although the patent can filter the incoming air through the air filter during the oxygen production process, the air filter needs to be replaced frequently to ensure the filtering effect. The existing air filter is very troublesome to install and can only be installed piece by piece. Therefore, the efficiency of replacing the air filter needs to be improved. In view of this, we propose an oxygen supply device for oxygen production. Utility Model Content
