Abstract

A movable industrial dust collector comprises mainly a base having a plurality of casters and a column provided with a columnar hole. The base further comprises a support set holding thereon a suction set communicating with the columnar hole of the base by means of a suction hose. A filtration set disposed on the suction set is provided with a filtration bag permitting the air drawn into the dust collector to be released and with a dust bag for use in depositing the dust and other unwanted objects drawn into the dust collector.

Claims

1. A movable industrial dust collector comprising:

(a) a base comprising a plurality of casters and a column disposed thereon and provided with a columnar hole passing through said base;

(b) a support set provided with a pair of tubular braces having lower ends thereof fastened to said base and with a support plate;

(c) a suction set supported securely on said support set and provided with a hollow guide box having an air inlet, two air outlets, and a motor with a suction fan attached to the shaft thereof in such a manner that it is positioned oppositely to said air inlet, said suction set further comprising a suction hose disposed between said base and said guide box in such a manner that it communicates with said air inlet and said columnar hole of said column; and

(d) a filtration set comprising a filtration bag and a dust bag disposed oppositely to each other, said filtration bag being in communication with one of said air outlets and said dust bag being in communication with the other of said air outlets.

2. A movable industrial dust collector according to claim 1, wherein said tubular brace comprises a pair of first tubular frames with lower ends thereof fastened to said base and a second tubular frame with both ends thereof fastened respectively to said first tubular frames.

3. A movable industrial dust collector according to claim 2, wherein said first and second tubular frames comprise therebetween a pair of connection means of columnar construction provided at midsection thereof with a circular flange and fitted respectively at both ends thereof into said first and second tubular frames.

4. A movable industrial dust collector according to claim 1, wherein said support plate comprises a flat portion extending along the long axis thereof and having a through hole, said flat portion further having curved portions of an angle bending inwardly and respectively from both sides thereof.

5. A movable industrial dust collector according to claim 4 further comprising a pair of connection means, with each fastened at upper end thereof to said curved portion and attached securely at lower end thereof to said base.

6. A movable industrial dust collector according to claim 1, wherein said guide box is composed of an upper housing with an open end having a flange disposed along the periphery thereof and of a lower housing with an open end having a flange disposed along the periphery thereof, said upper housing uniting with said lower housing by means of said flanges covered by a protective means.
