One end of each adsorption cylinder (21) A flow path switching device connection port 21a for connection to the switching device and an oxygen concentration gas discharge port 22a for discharging the oxygen enriched gas from the other end of each adsorption column are provided. By pushing in the cartridge, the cartridge is installed in the main body of the oxygen concentrator, and the ventilation port for connection to the flow path switching device, which is the cartridge side ventilation port, and the ventilation port for oxygen enrichment gas discharge are coupled to the corresponding main body side ventilation holes 36, 37, By pulling out the cartridge, the cartridge side vent is detached from the main body side vent. The replacement of the adsorbent is carried out by removing the old cartridge and replacing it with a new one.
Description
The present invention relates to a cartridge of an oxygen concentration apparatus for producing and supplying a gas having a high oxygen concentration by adsorbing nitrogen in air with an adsorbent.
As such an oxygen concentration apparatus, for example, an apparatus using a pressure swing adsorption (PSA) method has been conventionally known as disclosed in Japanese Unexamined Patent Application Publication No. 2008-148859 (Patent Document 1) have. In the oxygen concentration apparatus using this pressure swing adsorption method, an adsorbent is filled in the adsorption column. Then, air is introduced into the adsorption column, nitrogen of the introduced air is adsorbed by the adsorbent to concentrate the oxygen, and the oxygen-enriched gas is supplied. Since the adsorbent adsorbs a predetermined amount of nitrogen, the adsorption capacity is lowered. Therefore, the pressure in the adsorption column is lowered to release nitrogen adsorbed from the adsorbent to regenerate. In this way, the adsorbent repeatedly adsorbs and releases nitrogen, but deteriorates when the period of use is prolonged. Therefore, it is necessary to replace the deteriorated old adsorbent with a new adsorbent. Since this replacement work is difficult for a person who is not an expert, the oxygen concentrator is sent to a store or a management factory so that the operator exchanges the adsorbent and returns it to the user.
The problem to be solved is that it is necessary to send an oxygen concentrator to a store or a management plant to exchange the adsorbent
A cartridge (3) of an oxygen concentration apparatus of the present invention has a pair of adsorption columns (21) filled with an adsorbent and a flow path switching device (12) for changing the air supply flow path to be introduced into the adsorption columns, The switching device is operated to alternately switch the adsorption column to which the air is supplied and adsorb nitrogen from the air according to the pressure swing adsorption method to concentrate the oxygen and supply the oxygen enriched gas. The cartridge is accommodated in the main body of the oxygen concentrator and accommodates the pair of adsorption cylinders, and the one end of the cartridge is provided with a flow path switching device connection for connecting one end of each adsorption cylinder to the flow path switching device An oxygen concentration
Further, the other end of each adsorption column may communicate with the oxygen-enriched gas discharge vent through the check valve (28).
The cartridge-side ventilation hole and the main body-side ventilation hole may be coupled to each other with one side protruding and the other side recessed.
At one end of the cartridge, a
The cartridge has a
According to the present invention, at one end of a cartridge for accommodating a pair of adsorption columns, there are provided a flow passage switching device connection port for connecting one end portion of each adsorption container to the flow path switching device and a connection port for connection from the other end of each adsorption column to the oxygen- The cartridge can be installed in the main body of the oxygen concentrator by pushing the cartridge. Therefore, when the adsorbent deteriorates, the cartridge can be removed from the main body of the oxygen concentrator and separated, and a new replacement cartridge can be simply pushed in to perform the replacement operation. As a result, it is not necessary to send the main body of the oxygen concentrator to a store or a management factory for exchanging the adsorbent.
In addition, when the diluting gas introduced from the diluting gas vent is mixed with the oxygen-enriched gas in the cartridge, the one end of the cartridge is provided with the diluting gas vent for introducing the diluting gas, This is simplified.
When the cartridge has a handle and the handle is pivoted so that the cartridge can not be taken out by the engagement of the engaging portion and the guide portion, it is possible to prevent the cartridge from being inadvertently detached.
