Abstract
A gypsum slurry mixer output canister is provided, including a canister housing having an upper end, an opposite lower end and defining a canister interior, a cover secured to the upper end, a slurry inlet in operational relationship to the upper end, a spiral block associated with the upper end, and having a helical flow surface depending into the interior. A flow distributor is secured to the lower end and is in fluid communication with the interior, and a slurry outlet is defined by the lower canister housing end.
Claims20
A gypsum slurry mixer output canister, comprising:
- a canister housing having an upper end, an opposite lower end and defining a canister interior;
- a cover secured to said upper end;
- a slurry inlet in operational relationship to said upper end;
- a spiral block associated with said upper end, and having a helical flow surface depending into said interior;
- a flow distributor secured to said lower end and being in fluid communication with said interior, said flow distributor defining an outlet aperture having a plurality of radially-spaced lobes in fluid communication with a central opening of said outlet aperture, such that said lobes are located within a same plane as said central opening, wherein said lobes are each configured in a dovetail shape;
- and
- a slurry outlet defined by said lower canister housing end.
A gypsum slurry mixer output canister, comprising:
- a canister housing having an upper end, an opposite lower end and defining a canister interior;
- a cover secured to said upper end;
- a slurry inlet secured to said upper end;
- a spiral block associated with said upper end, and having a helical flow surface depending into said interior;
- a flow distributor secured to said lower end and being in fluid communication with said interior, said flow distributor including a plurality of radially inwardly projecting peripherally spaced teeth which define a plurality of lobe-shaped recesses in communication with a central opening, such that said lobe-shaped recesses are located between adjacent teeth, wherein said spaced teeth are each configured in a trapezoidal shape;
- and
- a slurry outlet defined by said lower canister housing end.
A gypsum slurry mixer output canister, comprising:
- a canister housing having an upper end, an opposite lower end and defining a canister interior;
- a cover secured to said upper end;
- a slurry inlet secured to said upper end;
- a spiral block associated with said upper end, and having a helical flow surface depending into said interior;
- a flow distributor secured to said lower end and being in fluid communication with said interior, said flow distributor including a plurality of radially inwardly projecting peripherally spaced teeth which define a plurality of lobe-shaped recesses in communication with a central opening, such that said lobe-shaped recesses are located between adjacent teeth, wherein said spaced teeth each define a radially inwardly tapered internal geometry with upper and lower surfaces which converge to an arcuate edge of said teeth, said arcuate edges forming an innermost circumference of said central opening;
- and
- a slurry outlet defined by said lower canister housing end.
A gypsum slurry mixer output canister, comprising:
- a canister housing having an upper end, an opposite lower end and defining a canister interior;
- a cover secured to said upper end;
- a slurry inlet secured to said upper end;
- a spiral block associated with said upper end, and having a helical flow surface depending into said interior;
- a flow distributor secured to said lower end and being in fluid communication with said interior, said flow distributor including a plurality of radially inwardly projecting peripherally spaced teeth which define a plurality of lobe-shaped recesses in communication with a central opening, such that said lobe-shaped recesses are located between adjacent teeth;
- a wall of said flow distributor defines a wedge-shaped cross-section, with a tip of said teeth forming a tip of said wedge shape;
- and
- a slurry outlet defined by said lower canister housing end.
