Abstract

A mobile vehicle mounted dry filtration system to support a grinder system used for removal of markings, creating rumble strips, or the like. Blowers create a vacuum for drawing debris and dust from the grinder system into a debris bin. Large debris is removed from the vacuum draw and remains in the bin for later disposal. Small particles and dust are drawn into parallel positioned filter cyclones that have a cyclonic separation followed by flexible and inexpensive bag filters. The flexible filters are cleaned using vibrating diaphragms mounted on the top of the filter cyclones subject to a reverse air flow by the blowers using slide valves. A polishing tank containing water receives the exhaust from the filter cyclones for removal of airborne particles and sound suppression.
