Organic debris collection device with curved blower conduit
First Claim
1. A curved blower conduit vented for pressure relief, having an entrance end connectable to an outlet portal of a blower and an exit end connectable to an inlet portal of a cargo container, for carrying the blower'"'"'s exhaust air stream to the cargo container, comprising in combination:
- a curved sector conduit extending between and joining said entrance end and said exit end, attachment means mounted on said sector conduit near said ends for securing said connections, an outer peripheral portion of said sector conduit having a first radius of curvature, an inner peripheral portion of said sector conduit having a second radius of curvature substantially smaller than said first radius of curvature, and vent means connecting the interior of said sector conduit, at a point of said inner peripheral portion intermediate between said entrance end and said exit end, to the external atmosphere, whereby the blower'"'"'s exhaust air stream is concentrated near the outer peripheral portion, relieving pressure in said cargo container by directing any return flow stream along the inner peripheral portion and out through said vent means.

Abstract
A curved blower exhaust conduit, delivering an air stream carrying pulverized or granulated entrained solids to a substantially sealed cargo chamber enclosure of fixed volume, is provided with a pressure relief vent mounted at an “inner” peripheral region of the curved conduit having a smaller radius of curvature than the outer peripheral region of the conduit, thereby connecting the interior of the curved conduit to the external atmosphere at a point where the majority of entrained solids are carried adjacent to the outer peripheral region by the air stream.
