Abstract

A portable, dust collection system for collection of wood dust generated in a wood floor sanding operation, the system comprising a plurality of portable blower motors comprising the primary static pressure generator positioned in series between the sanding tools and the collection container, this system having a plurality of collection hoses of increasing diameter between the sanding tools and the primary static pressure generator with intermediate blower motors positioned between the hoses where diameters increase, sanding tools having skirts for position thereon in distal proximate contact with the floor such that all dust is collected by the system.

Claims

1. A vacuum operated dust collection and removal system for hardwood floor sanding operations comprising:

a collection source for wood dust generated by a floor sanding operation;

a primary vacuum source in communication with said collection source;

a secondary vacuum source in communication with said primary vacuum source wherein said communication between said secondary vacuum source, said primary vacuum source, and said collection source comprises a series of first conduit members of a first diameter, said secondary vacuum source having one of said series of first conduit members of said first diameter extending therefrom and terminating in a first splitter coupling;

a plurality of second conduit members of a lesser diameter than and said first conduit member removably secured to said first splitter coupling and extending therefrom said second conduit members of said lesser diameter terminating in a first reducer coupling;

a third conduit member of a lesser diameter than said second conduit member, said third conduit member removably secured to said reducer coupling and terminating in a second splitter coupling; and

a plurality of fourth conduit members of lesser diameter than said third conduit member, said fourth conduit members being removably secured to a machine performing an operation on said floor.

2. The vacuum operated dust collection and removal system in accordance with claim 1 wherein said primary vacuum source comprises three blower motors positioned proximate each other in series.

3. The vacuum operated dust collection and removal system in accordance with claim 1 wherein said secondary vacuum source comprises a fourth blower motor positioned down stream from said primary vacuum source.

4. A vacuum operated dust collection and removal system in accordance with claim 1 wherein supplementary vacuum sources may be positioned between said second and third and third and fourth conduit members.

5. The vacuum operated dust collection and removal system in accordance with claim 1 wherein said collection source comprises a collection bag having an inlet port for connection with said first conduit member from said primary vacuum source, said collection bag being positioned exteriorly from said floor sanding operation.

6. The vacuum operated dust collection and removal system in accordance with claim 1 wherein said first conduit, said second conduit, said third conduit, and said fourth conduit members decrease in diameter from six inches, to five inches, to four inches, to three inches respectively.

7. The vacuum operated dust collection and removal system in accordance with claim 1 wherein said first conduit member extends from said secondary vacuum system to said first splitter coupling, a distance proximating 25 feet.

8. The vacuum operated dust collection and removal system in accordance with claim 1 wherein second conduit member extends from said first splitter coupling to said reducer coupling, a distance proximating 25 feet.

9. The vacuum operated dust collection and removal system in accordance with claim 1 wherein said third conduit member extends from said reducer coupling to said second splitter coupling, a distance proximating 25 feet.

10. The vacuum operated dust collection and removal system in accordance with claim 1 wherein said fourth conduit members can each extend a distance of from between 60 to 100 feet.
