Claims17
A dust mitigation system for a mobile sweeper, the dust mitigation system including;
- a cover to at least partially cover one or more brushes of the mobile sweeper;
- a dust collector including:
- at least one fan;
- and one or more filters;
- at least one duct fluidly connecting the cover with the dust collector;
- and at least one separator for separating dust and/or debris from air, the at least one separator including:
- one or more blades to move the air through the at least one separator;
- and a pre-filter located at least partially around the one or more blades, the pre-filter having a plurality of openings to enable dust and/or debris below a predetermined size to pass through the plurality of openings, and an exhaust aperture for larger particles to exit the pre-filter, the pre-filter tapered from an inlet of the pre-filter to the exhaust aperture.
5 more elements
A panel filter for filtering dust or debris from air, the panel filter having:
- a filter;
- a frame surrounding the filter;
- one or more resilient or elastic members to mount the frame to a dust collector, wherein the one or more resilient or elastic members are adapted to enable movement during operation of the dust collector to shake the filter to dislodge any dust or debris that may be stuck in or blocking the filter;
- wherein the panel filter is installable in a dust collector of a dust mitigation system, the dust mitigation system including:
- at least one fan;
- at least one duct fluidly connecting the cover with the dust collector;
- and at least one separator for separating dust and/or debris from air, the at least one separator including:
- one or more blades to move the air through the at least one separator;
- and a pre-filter located at least partially around the one or more blades, the pre-filter having a plurality of openings to enable dust and/or debris below a predetermined size to pass through the plurality of openings, and an exhaust aperture for larger particles to exit the pre-filter, the pre-filter tapered from an inlet of the pre-filter to the exhaust aperture.
6 more elements
A method of filtering air, including the steps of:
- sweeping a ground surface with a mobile sweeper;
- moving air with swept dust and/or debris through at least one separator having a pre-filter to separate different sized dust and/or debris;
- moving the air through a filter to filter the air;
- and shaking the pre-filter and the filter to dislodge dust and/or debris such that the dust and debris can fall into a hopper;
- wherein the at least one separator includes:
- one or more blades to move the air through the at least one separator;
- and a pre-filter located at least partially around the one or more blades, the pre-filter having a plurality of openings to enable dust and/or debris below a predetermined size to pass through the plurality of openings, and an exhaust aperture for larger particles to exit the pre-filter, the pre-filter tapered from an inlet of the pre-filter to the exhaust aperture.
