ANLEGG FOR KONTINUERLIG SUGETRANSPORT VED HJELP AV TRANSPORTLUFT.

摘要

Waste material is sucked away from different suction points (1-8) and is transported in branch conduits (12) to the common collecting point comprising a container (9). The dimensions of the branch conduits (12) and the collecting container (9) are thus chosen that the air velocity in the conduits (12) is sufficient, but in the container (9) insufficient to carry the waste material in the air stream. This will cause the waste material to be extracted in the container (9) and collected in the bottom thereof. The air stream is then passed through a filter (10) before it is returned to the interior space of the building. In the upper portion of the collecting container there are separate openings (11) for the branch conduits (12) connected to the container (9). The lower portion of the container is formed with a funnel-shaped bottom for convenient collection of the waste material. The air flow through the openings (11) in the container (9) or in the branch conduits (12) are controllable by means of individually operated valves (20).
