Apparatus for the production of oxygen

Claim 2

A modularized PSA machine comprising a housing; said machine comprising a single bed of adsorbent material, a surge tank, a process solenoid valve, and a pressure regulator; means to join said single bed, said surge tank, said process solenoid valve and said pressure regulator together into a single module, means to removably mount said single module into said housing; whereby said module may be pre-fabricated apart from said housing, and then easily removed from and replaced into said housing to facilitate service and maintenance of said PSA machine.

Claim 3

The machine of claim 1, said single module comprising means to removably mount said single bed into said single module so as to permit removal of said single bed from said machine and from said single module without removing said entire single module from said PSA machine.

Claim 4

The machine of claim 2, last mentioned removable mounting means comprising clamp means joined to said surge tank, and bolt means to removably secure said bed into said clamp means.

Claim 5

The machine of claim 1, said housing comprising a bulkhead fixed therein; said means to removably mount said single module into said housing comprising clamp means fixed to said surge tank and screw means removably joining said clamp means to said fixed bulkhead.

Claim 6

The machine of claim 1, said means joining said single bed, said surge tank, said process solenoid valve and said pressure regulator together comprising at least in part the air flow piping means needed in any event to functionally interconnect said single bed, said surge tank, said process solenoid valve and said pressure regulator together, whereby said air flow piping means serves as both air flow conduit means and structural interconnecting means.

Claim 7

The machine of claim 1, and a second pre-fabricated module comprising an air compressor and a control solenoid valve directing air flow with respect to said air compressor, means to mount said control valve on said compressor, said mounting means comprising the air flow piping between said control valve and said compressor, means to interconnect said first mentioned single module and said second module together inside said housing, and said two modules together comprising effectively the entire functioning parts of said machine.

Claim 8

In a PSA machine housing a single adsorbent bed and a housing, the improvement comprising a pre-fabricated module comprising an air compressor and a control solenoid valve directing air flow with respect to said air compressor, means to mount said control valve on said compressor, said mounting means comprising the air flow piping between said control valve and said compressor, whereby said air flow piping between said air compressor and said control valve serves the dual functions of both air flow conduit means and also physical mounting means therebetween, and means to mount said module into said housing, whereby said module may be pre-fabricated apart from said housing, and then easily removed from and replaced into said housing to facilitate service and maintenance of said PSA machine.

Claim 9

In a PSA machine housing a single adsorbent bed and a housing, the improvement comprising a pre-fabricated module comprising an air compressor and a control solenoid valve directing air flow with respect to said air compressor, means to mount said control valve on said compressor, said mounting means comprising the air flow piping between said control valve and said compressor, whereby said air flow piping between said air compressor and said control valve serves the dual functions of both air flow conduit means and also physical mounting means therebetween, and means to mount said module into said housing, whereby said module may be pre-fabricated apart from said housing, and then easily removed from and replaced into said housing to facilitate service and maintenance of said PSA machine.

Claim 10

The machine of claim 7, said machine comprising a surge tank, a process solenoid valve, and a pressure regulator; means to join said single bed, said surge tank, said process solenoid valve and said pressure regulator together into a single module, means to removably mount said single module into said housing; whereby said module may be pre-fabricated apart from said housing, and then easily removed from and replaced into said housing to facilitate service and maintenance of said PSA machine.

Claim 11

The machine of claim 7, said single module comprising means to removably mount said single bed into said single module so as to permit removal of said single bed from said machine and from said single module without removing said entire single module from said PSA machine.

Claim 12

The machine of claim 9, last mentioned removable mounting means comprising clamp means joined to said surge tank, and bolt means to removably secure said bed into said clamp means.

Claim 13

The machine of claim 7, said housing comprising a bulkhead fixed therein; said means to removably mount said single module into said housing comprising clamp means fixed to said surge tank and screw means removably joining said clamp means to said fixed bulkhead.

Claim 14

The machine of claim 7, said means joining said single bed, and surge tank, said process solenoid valve and said pressure regulator together comprising at least in part the air flow piping means needed in any event to functionally interconnect said single bed, said surge tank, said process solenoid valve and said pressure regulator together, whereby said air flow piping means serves as both air flow conduit means and structural interconnecting means.
