Abstract

An apparatus includes a tube having an inlet and an outlet. A plurality of apertures are spaced along a wall of the tube. Flow inducers are applied to the inlet for distributing the flow between the plurality of apertures. The flow inducers may include at least one venturi portion located within the tube. The tube is typically used to remove material contained within a hopper wherein the angle of a collection face, of the hopper, may be reduced and still effectively remove all the material applied to the collection face.

Claims

1. An apparatus comprising:

a tube having an inlet, an outlet, and an internal area;

suction means being in fluid communication with said outlet for inducing a flow through said tube;

a plurality of aperture means spaced along a wall of the tube for introducing a particulate material to the internal area; and

a plurality of flow boosting means, applied along the length of said tube between the inlet and the outlet, for maintaining the velocity of said flow throughout the length of said tube whereby said particulate material is conveyed a greater distance through said pipe than is possible without the flow boosting means.

2. The apparatus as described in claim 1, wherein the flow boosting means comprises:

at least one venturi portion.

3. The apparatus as described in claim 2, wherein a venturi is created between the venturi portion and the tube.

4. The apparatus as described in claim 1, further comprising:

a hopper defining an interior portion, the interior portion is in fluid communication with an internal area of the tube via said apertures.

5. The apparatus as described in claim 4, wherein the hopper is configured to permit collecting of particulate material from abrasive blasting applications.

6. The apparatus as described in claim 1, wherein the spacing between the apertures is varied along the length of the tube.

7. The apparatus as described in claim 1, wherein the fluid is a compressible fluid.

8. The apparatus as described in claim 1, wherein the particulate material contains abrasives.

9. The material as described in claim 1, wherein the particulate material contains remnants from abrasive blasting.
