Abstract

An industrial vacuum cleaner for collecting fibers collecting lint and the like and using said fibers as a filtration medium for air being exhausted from the cleaning system. The apparatus includes a positive displacement pump which draws the lint-laden air into a cylindrical housing having a plastic bag positioned therein which has holes provided therein. The plastic bag is, in turn, carried into a woven filter bag which is, in turn, carried within a rigid cylindrical mesh liner. As a result, the lint collected is removed from the air and builds up along the side walls of the plastic liner providing a filtration medium for lint-laden air subsequently drawn therein.

Claims

1. An industrial vacuum cleaning system for collecting fibers containing lint and the like using said collected fibers as a filtration medium for subsequent lint laden air collected comprising:

a positive displacement vacuum pump;

a motor driving said positive displacement vacuum pump producing a high vacuum;

a vertically extending cylindrical housing having a closed bottom, and side wall, and an open top;

a removable top extending over said open top;

a vacuum hose;

a vacuum hose receiver carried on said removable top having an opening communicating with the interior of said cylindrical housing through which media collected by said vacuum hose passes into said cylindrical housing;

a cleaning head carried on a remote end of said vacuum hose;

a rigid cylindrical mesh liner carried in said housing of a smaller size than said cylindrical housing producing a space between said cylindrical housing and said mesh liner;

a porous woven filter bag carried in said mesh cylindrical liner; and

a plastic bag carried within said woven filter bag having spaced holes provided in a substantially uniform pattern throughout the entire plastic bag, said plastic bag having spaced holes of approximately one-half of an inch (1/2") uniformly spaced throughout with the remainder of said plastic bag being non-porous;

said filter bag and said plastic bag each having an open top for receiving media entering said cylindrical housing through said vacuum hose, and

an input of said positive displacement vacuum pump communicating with a lower portion of said cylindrical housing for drawing media-laden air into said cylindrical housing, through said holes provided in said plastic bag, said porous woven filter bag, said mesh liner and through the space provided between said cylindrical mesh liner and the inner wall of said cylindrical housing.

said positive displacement vacuum pump producing a positive air flow causing said media entering said plastic bag to first cover said holes provided in said plastic bag and compacting said media extending over said holes filtering any subsequent media-laden air entering said cylindrical housing producing a tightly compacted bag of media while said positive displacement vacuum pump maintains a constant high vacuum at said cleaning head.

2. The industrial vacuum cleaner as set forth in claim 1 further comprising:

said vacuum hose receiver including,

(i) an arcuate deflection plate joined by spaced vertically extending side walls;

(ii) a lower end of said deflection plate terminating inside said cylindrical housing in a central portion thereof;

(iii) an upper end of said deflection plate along with said side walls providing an entrance opening, and

(iv) an adapter plate extending over said entrance opening having a tubular member extending outwardly therefrom for receiving an end of said vacuum hose.

3. The industrial vacuum cleaner as set forth in claim 2 further comprising:

said spaced holes in said plastic being approximately two inches from the next adjacent hole.

4. An industrial vacuum cleaning system for collecting fibers containing lint and the like and using said collected fibers as a filtration medium for subsequent lint laden air collected comprising:

a positive displacement vacuum pump;

a motor driving said postive displacement vacuum pump producing a high vacuum;

a vertically extending cylindrical housing having a closed bottom, and side wall, and an open top;

a removable solid top extending over said open top;

a vacuum hose;

a vacuum hose receiver carried on said removable top having an opening communicating with the interior of said cylindrical housing through which media collected by said vacuum hose passes into said cylindrical housing;

a cleaning head carried on a remote end of said vacuum hose;

a rigid cylindrical mesh liner carried in said housing of a smaller size than said cylindrical housing producing a space between said cylindrical housing and said mesh liner;

a porous woven filter bag carried in said mesh cylindrical liner; and

a collection bag carried within said woven filter bag having spaced holes provided in a substantially uniform pattern throughout substantially the entire collection bag, with the remainder of said collection bag being non-porous;

said filter bag and said collection bag each having an open top for receiving media entering said cylindrical housing through said vacuum hose,

a pressure relief valve carried in the wall of said cylindrical housing preventing a vacuum buildup within said housing beyond a predetermined value;

an input of said positive displacement vacuum pump communicating with a lower portion of said cylindrical housing for drawing media-laden air into said cylindrical housing, through said holes provided in said collection bag, said porous woven filter bag, said mesh liner and through the space provided between said cylindrical mesh liner and the inner wall of said cylindrical housing;

said positive displacement vacuum pump producing a positive air flow causing said media entering said collection bag to first cover said holes provided in said collection bag and compacting said media extending over said holes filtering any subsequent media-laden air entering said cylindrical housing producing a compacted bag of media while said positive displacement vacuum pump maintains a constant high vacuum at said cleaning head.
