Apparatus for distributing slurries

Claim 2

Claim 8

The slurry distributor as set forth in claim 6 in which: the valve means are mounted with each compartment for vertical reciprocating movement between open and closed positions.

Claim 9

The slurry distributor as set forth in claim 6 in which: means comprising a vertically-disposed stationary guide tube is located within each compartment with its axis aligned with the center of the discharge opening; and, said valve means is guided for reciprocating telescopic movement within said guide tube.

Claim 10

The slurry distributor as set forth in claim 6 in which a functionally independent pneumatic servomotor is mounted within each compartment above the discharge opening therein, said servomotor being operatively connected to said valve means and effective upon actuation to at least open same.

Claim 11

The slurry distributor as set forth in claim 9 wherein an axially adjustable connection is interposed between said valve means and said servomotor, said connection being effective upon actuation to raise and lower the valve means so as to vary its seating pressure in closed position.

Claim 12

The slurry distributor as set forth in claim 6 in which: the valve means comprise tubular members open at the lower end thereof, said lower end comprising a downwardly and inwardly tapered portion.

Claim 13

The slurry distributor as set forth in claim 11 in which a rubber jacket covers the downwardly and inwardly tapered end portion of each valve.

Claim 14

The slurry distributor as set forth in claim 6 wherein each valve means is independently movable between an open position and a closed position seated within said discharge opening, the lower end of said valve means in open position being lower than the inlet opening and bypass means.

Claim 15

The slurry distributor as set forth in claim 1 wherein the bypass means in each compartment is positioned at a level substantially lower than the inlet thereto.

Claim 16

The slurry distributor as set forth in claim 1 wherein both the bypass means and inlet openings are spaced above the bottom of their respective compartments.

Claim 17

The slurry distributors set forth in claim 1 wherein the first and second wall means are cylindrical.

Claim 18

A stationary slurry distributor which comprises: a horizontally-disposed base; first wall means supported on said base cooperating therewith to define an open-topped reservoir effective to receive and retain a slurry delivered thereto; second wall means surrounding said first wall means in spaced relation outside thereof cooperating therewith and with said base to define an inner chamber encircling said reservoir; third wall means with an outlet therein surrounding said second wall means in spaced relation outside thereof cooperating therewith and with said base to define an outer chamber encircling said inner chamber; partition walls dividing the interior of said inner chamber into a plurality of individual compartments; the portions of said base underlying each compartment having a discharge opening therein, the portions of said first wall separating each compartment from the reservoir containing an inlet opening, the portions of said second wall within each compartment containing bypass means, and said bypass means and inlet opening within each compartment being angularly-offset relative to one another such that the slurry entering said compartment from the reservoir will essentially all leave the latter through said discharge opening when it is open; stopper-type valve means within each compartment independently operable to plug and unplug the discharge opening therein; and dam-forming means disposed within the outlet in the third wall means, said bypass means being effective to transfer slurry from said inner chamber to said outer chamber when the discharge opening within the compartment containing said bypass means is plugged, and said dam-forming means being of a height effective to discharge the contents of said outer chamber through the outlet without letting it re-enter said inner chamber.

Claim 19

A stationary slurry distributor which comprises: a horizontally-disposed base; first wall means supported on said base cooperating therewith to define an open-topped reservoir effective to receive and retain a slurry delivered thereto; second wall means surrounding said first wall means in spaced relation outside thereof cooperating therewith and with said base to define an inner chamber encircling said reservoir; third wall means with an outlet therein surrounding said second wall means in spaced relation outside thereof cooperating therewith and with said base to define an outer chamber encircling said inner chamber; partition walls dividing the interior of said inner chamber into a plurality of individual compartments; the portions of said base underlying each compartment having a discharge opening therein, the portions of said first wall separating each compartment from the reservoir containing an inlet opening, the portions of said second wall within each compartment containing bypass means, and said bypass means and inlet opening within each compartment being angularly-offset relative to one another such that the slurry entering said compartment from the reservoir will essentially all leave the latter through said discharge opening when it is open; stopper-type valve means within each compartment independently operable to plug and unplug the discharge opening therein; and dam-forming means disposed within the outlet in the third wall means, said bypass means being effective to transfer slurry from said inner chamber to said outer chamber when the discharge opening within the compartment containing said bypass means is plugged, and said dam-forming means being of a height effective to discharge the contents of said outer chamber through the outlet without letting it re-enter said inner chamber.

Claim 20

A stationary slurry distributor which comprises: a horizontally-disposed base; first wall means supported on said base cooperating therewith to define an open-topped reservoir effective to receive and retain a slurry delivered thereto; second wall means surrounding said first wall means in spaced relation outside thereof cooperating therewith and with said base to define a chamber encircling said reservoir; partition walls wall dividing the interior of said chamber into separate compartments; the portions of said base underlying each compartment having a discharge opening therein, the portions of said first wall separating each compartment from the reservoir containing an inlet opening; a mounting plate bridging the gap between the first and second wall means above each compartment; and a vertically-disposed guide tube suspended from the underside of said mounting plate for horizontal adjustment relative thereto so as to place the axis thereof in alignment with the center of the discharge opening therein; and, stopper-type valve means mounted within said guide tube for reciprocating movement therein between an open position and a closed position plugging said discharge opening independently operable to plug and unplug the discharge opening therein.
