Abstract
A dust filtering and collection system for filtering dust particles from an incoming dust laden air stream is disclosed. When used is a mobile vacuum loading/unloading vehicle, the system separates dust particles from the incoming dust laden air stream in a dust filtering and collection canister or chamber and then exhausts the dust cleansed air stream from the canister or chamber. Dust particles filtered from the dust cleansed air stream are collected as accumulated product particles along a bottom area of the canister or chamber. The accumulated product particles may then be transferred to a storage chamber from which the incoming dust laden air stream has emanated. In addition, the dust filtering system of the present invention includes a plurality of juxtaposed hollow polymer tubes which are suspended and supported by a transverse panel extending across the canister or chamber adjacent an upper end thereof, with each hollow polymer tube being sealed relative to the transverse panel and having a porosity permitting air to be drawn therethrough while removing dust particles from the incoming dust laden air stream. The construction and arrangement of the hollow polymer tubes, with…
