Separation device

Claim 1

A device for separating precipitation and/or floatation components from a liquid having a sump with an inclined wall and sidewalls, further having a separation assembly with a number of inclined separation passages, and being supported by said inclined wall, between two adjacent sidewalls, the improvement comprising: a baffle in the sump disposed adjacent the upper end of the separation assembly and dividing the sump into a supply and a discharge chamber, the baffle having an aperture and lying on and being sealed against the upper end face of the assembly around said aperture; means for sealing the baffle against the sidewalls as well as against the inclined wall; first stop means on said inclined wall and engaging the assembly for preventing iT from sliding down, said assembly removably resting on said inclined wall; and second stop means engaging the lower edge of the baffle and preventing upward movement thereof.

Claim 2

A device for separating precipitation and/or floatation components from a liquid having a sump with an inclined wall and sidewalls, further having a separation assembly with a number of inclined separation passages, and being supported by said inclined wall, between two adjacent sidewalls, the improvement comprising: a baffle in the sump disposed adjacent the upper end of the separation assembly and dividing the sump into a supply and a discharge chamber, the baffle having an aperture and lying on and being sealed against the upper end face of the assembly around said aperture; means for sealing the baffle against the sidewalls as well as against the inclined wall; first stop means on said inclined wall and engaging the assembly for preventing iT from sliding down, said assembly removably resting on said inclined wall; and second stop means engaging the lower edge of the baffle and preventing upward movement thereof.

Claim 4

A device for separating precipitation and/or floatation components from a liquid having a sump with an inclined wall and sidewalls, further having a separation assembly with a number of inclined separation passages in a casing, and being disposed for support by said inclined wall and between two adjacent sidewalls, the improvement comprising: the separation assembly with casing being removable from the sump; baffle means in the sump disposed at the upper end of the separation assembly separated therefrom and from the sump and dividing the sump into a supply and a discharge chamber, and having a portion extending adjacent the bottom of the assembly at the upper end thereof and extending up to a level above the normal liquid level in the sump; the baffle means having aperture with a hortizontally extending baffle edge above the bottom of the assembly at the upper end thereof; means for sealing the baffle against the assembly, and including sealing means extending transversely to the hortizontally extending baffle edge; additional means separated from the baffle as well as from said first baffle sealing means for sealing the baffle laterally against and alongside the walls; further means for sealing the baffle relative to the inclined wall of said sump as regards supply and discharge chambers and extending parallel to the said baffle edge; and stop means engaging the assembly at the lower end for preventing said assembly from sliding down on said inclined wall of the sump.

Claim 5

A device for separating precipitation and/or floatation components from a liquid having a sump with an inclined wall and sidewalls, further having a separation assembly with a number of inclined separation passages in a casing, and being disposed for support by said inclined wall and between two adjacent sidewalls, the improvement comprising: the separation assembly with casing being removable from the sump; baffle means in the sump disposed at the upper end of the separation assembly separated therefrom and from the sump and dividing the sump into a supply and a discharge chamber, and having a portion extending adjacent the bottom of the assembly at the upper end thereof and extending up to a level above the normal liquid level in the sump; the baffle means having aperture with a hortizontally extending baffle edge above the bottom of the assembly at the upper end thereof; means for sealing the baffle against the assembly, and including sealing means extending transversely to the hortizontally extending baffle edge; additional means separated from the baffle as well as from said first baffle sealing means for sealing the baffle laterally against and alongside the walls; further means for sealing the baffle relative to the inclined wall of said sump as regards supply and discharge chambers and extending parallel to the said baffle edge; and stop means engaging the assembly at the lower end for preventing said assembly from sliding down on said inclined wall of the sump.

Claim 6

A device according to any one of Claims 3, wherein the separation assembly comprises, at least at its lower end, substantially vertically extending ducts interconnecting superposed crests or valleys of separation passages of the assembly, which ducts are closed by transverse plates joining, in the case of ducts communicating with crests, a partition wall separating the adjacent chamber from a collecting chamber for sediment communicating with the other ducts, the connection between the partition wall and the adjacent transverse plates or between two adjacent parts of the wall is such that removal of the separation assembly is not impeded.

Claim 9

A device for separating precipitation and/or floatation components from a liquid having a sump with an inclined wall and sidewalls, further having a separation assembly with a number of inclined separation passages, and being disposed for support by said inclined wall between two adjacent sidewalls, the improvement comprising: a baffle mounted in the sump adjacent the inclined wall and constituting a continuation of the assembly but being separable therefrom, the baffle extending upwardly beyond said inclined wall and having side portions extending further beyond the normal liquid level in the sump; the separation assembly having a casing with side walls and a lower wall provided with an aperture, the side walls of the casing extending above the normal liquid level in the sump; an upper end of the baffle disposed for serving as an overflow weir, said side portions of the baffle extending beyond the weir; strips for sealing the said side portions of the baffle against the side walls of the sump and extending above the normal liquid level in the sump; and sealing means for sealing the lower wall of the casing against the baffle and extending along the weir and one edge of the aperture, as well as for sealing along said side portions of the baffle, thereby sealing the assembly from the interior of the sump beyond said weir and opposite the assembly.

Claim 10

A device for separating precipitation and/or floatation components from a liquid having a sump with an inclined wall and sidewalls, further having a separation assembly with a number of inclined separation passages, and being disposed for support by said inclined wall between two adjacent sidewalls, the improvement comprising: a baffle mounted in the sump adjacent the inclined wall and constituting a continuation of the assembly but being separable therefrom, the baffle extending upwardly beyond said inclined wall and having side portions extending further beyond the normal liquid level in the sump; the separation assembly having a casing with side walls and a lower wall provided with an aperture, the side walls of the casing extending above the normal liquid level in the sump; an upper end of the baffle disposed for serving as an overflow weir, said side portions of the baffle extending beyond the weir; strips for sealing the said side portions of the baffle against the side walls of the sump and extending above the normal liquid level in the sump; and sealing means for sealing the lower wall of the casing against the baffle and extending along the weir and one edge of the aperture, as well as for sealing along said side portions of the baffle, thereby sealing the assembly from the interior of the sump beyond said weir and opposite the assembly.
