Abstract
Abstract A device for separating sewage solids from sewage fluids. The device is characterized by a variably dimensioned orifice for tangentially jetting a stream of fluid into a vortexing chamber supported in an upwardly spaced relationship with an accumulator for descending solids. A flexible closure member is extended across the orifice in the direction of the flow and is provided with a first surface against which fluids passing through the orifice impinge and a second surface against which fluids within the chamber impinge, whereby the effective dimension of the orifice is varied in response to variations in the flow characteristics of the stream.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
152 words
A solids separating device comprising a substantially cylindrical vortexing chamber having upper and lower ends, means for jetting a substantially tangential flow of fluids containing solids into the vortexing chamber, including means defining an orifice in the chamber and means comprising a flexible closure member extended across said orifice, means substantially closing the upper end of the vortexing chamber providing an outlet conduit extended therethrough substantially concentrically of the vortexing chamber, an accumulator mounted in a substantially upright position, means supporting the vortexing chamber in an upwardly spaced relationship with said accumulator, means defining a conduit interconnecting the lower end of the vortexing chamber with the upper end of the accumulator including a valve Operable to open and to close the conduit, and means in the lower end of the accumulator movable between a closed position, for retaining solids descending thereto through the conduit and an opened position for releasing said solids.
Claim 2
Dependent Claim
152 words
A solids separating device comprising a substantially cylindrical vortexing chamber having upper and lower ends, means for jetting a substantially tangential flow of fluids containing solids into the vortexing chamber, including means defining an orifice in the chamber and means comprising a flexible closure member extended across said orifice, means substantially closing the upper end of the vortexing chamber providing an outlet conduit extended therethrough substantially concentrically of the vortexing chamber, an accumulator mounted in a substantially upright position, means supporting the vortexing chamber in an upwardly spaced relationship with said accumulator, means defining a conduit interconnecting the lower end of the vortexing chamber with the upper end of the accumulator including a valve Operable to open and to close the conduit, and means in the lower end of the accumulator movable between a closed position, for retaining solids descending thereto through the conduit and an opened position for releasing said solids.
Claim 3
Dependent Claim
48 words
The device of claim 1 in which the outlet conduit of the vortexing chamber extends downwardly into the vortexing chamber and a bleeding valve is provided in the closed upper end of the vortexing chamber to bleed air trapped therein above the lower end of the outlet conduit.
Claim 4
Dependent Claim
56 words
The device of claim 1 wherein said flexible closure member comprises a displaceable flap supported within said chamber and extended across said orifice in the direction of said flow, having a given surface disposed for impingement thereagainst of fluid passing through the orifice and an opposite surface disposed for impingement thereagainst of fluid within said chamber.
Claim 5
Dependent Claim
33 words
The device of claim 1 wherein said flap comprises the distal end a curved, rectangular sheet of flexible material supported in circumscribing relation with a portion of the internal surface of said chamber.
Claim 6
Dependent Claim
222 words
In a device for use in separating sewage solids from sewage fluids, the improvement comprising: A. a substantially cylindrical vortexing chamber having an upper and a lower portion; B. means defining within said chamber an orifice for jetting a flow of fluid containing sewage solids into the vortexing chamber adjacent to the upper portion thereof; C. means substantially closing the upper portion of the vortexing chamber and having an outlet conduit extended therethrough in a substantially concentric relationship with the chamber; D. an upright accumulator; E. means supporting the vortexing chamber in an upwardly spaced relationship with said accumulator; F. a conduit interconnecting the lower portion of the vortexing chamber with the upper portion of the accumulator; G. an operable valve mounted in said conduit; H. operable closure means disposed in the lower portion of the accumulator for selectively retaining solids therewithin; and I. a flexible flap extended across said orifice in the direction of the flow of fluid interiorly of the vortexing chamber having an inner surface disposed for oblique impingement thereagainst of fluid passing through said orifice for establishing a tangentially directed flow from said orifice and an opposite surface disposed for acute impingement thereagainst of fluid within the vortexing chamber, whereby opposed forces incident to such impingement automatically position the flap for regulating the effective size of the orifice.
Claim 7
Dependent Claim
222 words
In a device for use in separating sewage solids from sewage fluids, the improvement comprising: A. a substantially cylindrical vortexing chamber having an upper and a lower portion; B. means defining within said chamber an orifice for jetting a flow of fluid containing sewage solids into the vortexing chamber adjacent to the upper portion thereof; C. means substantially closing the upper portion of the vortexing chamber and having an outlet conduit extended therethrough in a substantially concentric relationship with the chamber; D. an upright accumulator; E. means supporting the vortexing chamber in an upwardly spaced relationship with said accumulator; F. a conduit interconnecting the lower portion of the vortexing chamber with the upper portion of the accumulator; G. an operable valve mounted in said conduit; H. operable closure means disposed in the lower portion of the accumulator for selectively retaining solids therewithin; and I. a flexible flap extended across said orifice in the direction of the flow of fluid interiorly of the vortexing chamber having an inner surface disposed for oblique impingement thereagainst of fluid passing through said orifice for establishing a tangentially directed flow from said orifice and an opposite surface disposed for acute impingement thereagainst of fluid within the vortexing chamber, whereby opposed forces incident to such impingement automatically position the flap for regulating the effective size of the orifice.
Claim 8
Dependent Claim
35 words
The improvement of claim 5 further comprising a bleeding valve supported at the closed upper portion of the vortexing chamber for bleeding air trapped within the chamber above the lower end of the outlet conduit.
