ABSTRACT:
A multi-compartment vacuuming machine which maintains a high flow rate capacity and low resistance from obstructions in the flow path through arrangement of the multiplicity of vacuum canisters in parallel so that obstructed flow in one filter canister will not impair the flow through the remainder of the filter canisters. The flow path of the dirty fluid is arranged such that there is a straight line from the dirty fluid to the most distal filter canister so that the most distal canister fills up first and then intermediate filter canisters are filled. The transverse path leads from the main dirty inlet flow tube to the various filter canisters. In the preferred embodiment, the canister inlet flow tube to each filter canister is generally perpendicular to the dirty air inlet tube and the vacuum suction motor is remote from the most distal of the canisters. Variations on this embodiment include having the canister inlet flow tubes to the various filter canisters set at an angle relative to the dirty air inlet tube, having the vacuum suction motor located adjacent the most distal filter canister, and having the flow path from the dirty air inlet directed in a straight line to one of the filter canisters and therefore generally perpendicular to the flow path of the canister inlet tubes of the other canisters. When a filter canister is filled with particulates, means are provided to shut off air flow to that filter canister and further means are provided to disengage the filter or the filter canister from the vacuum apparatus so that it can be cleaned and if desired the filter can be replaced. In an alternative embodiment, instead of a multiplicity of filter canisters there is a multiplicity of filter compartments in one large enclosure and one sheet filter is used for all compartments.
