Abstract

See full text

A negative-pressure dust collector system employs a dust separator device to separate the dust that is entrained in a stream of dust-laden air, exhausts the air stream to a vacuum-inducing machine, and discharge the separated dust downward into a bagger arrangement. The latter employs an open-bottom generally rigid hopper with a grid across its open bottom. A flexible dust collection bag is clamped onto an exterior of the hopper and hangs from the hopper. Under vacuum, the bag closes off the open bottom of said hopper. The grid has openings dimensioned so that dust in the container passes freely through the grid when the vacuum-inducing machine is shut off, but so that the bag may be sucked up against the grid, but not sucked into the open-bottom hopper when vacuum is applied. A flexible apron may be attached to the bottom of the hopper between the grid and the dust-collection bag.
