Slurry mixer gate having enhanced extractor ports

1. A discharge gate for delivering a mixed slurry from a gypsum slurry mixer, comprising:

a first extractor port configured for generating a first density slurry for a first gypsum layer;

a second extractor port configured for generating a second density slurry for a second gypsum layer;

a channel defined by a front panel and a side panel of the discharge gate for delivering the first and second density slurries from the slurry mixer;

a pocket configured for receiving the mixed slurry is disposed on an inner surface of the front panel;

said pocket has a gradually inclined ramp around an upper peripheral circumference of the pocket, continuously following along a contour of an outer edge of the pocket; and

wherein the first extractor port extends semi-tangentially from the front panel of the discharge gate, and is connected in fluid communication with the front panel via the channel and a first slurry passageway disposed within the first extractor port for delivering the first density slurry.

2. The discharge gate of claim 1 , wherein the second extractor port extends transversely from the side panel of the discharge gate, and is connected in fluid communication with the side panel via the channel and a second slurry passageway disposed within the second extractor port for delivering the second density slurry.

3. The discharge gate of claim 1 , wherein an indented seat is disposed at one end of the front panel, and an opposite end of the front panel is attached to the side panel.

4. The discharge gate of claim 1 , wherein the pocket begins near one end of the front panel, and ends at an opposite end near an opening of the first slurry passageway.

5. The discharge gate of claim 1 , wherein the pocket has a predetermined angle defined by an inner surface of the pocket, the angle being measured between opposite edges of the pocket relative to a longitudinal axis of the first extractor port.

6. The discharge gate of claim 1 , wherein an opening of the first slurry passageway is entirely encircled within the space defined by the pocket when viewed from a side facing an opening of the pocket.

7. The discharge gate of claim 1 , wherein a first opening of the first slurry passageway is disposed adjacent a second opening of a second slurry passageway disposed within the second extractor port for delivering the second density slurry.

8. The discharge gate of claim 1 , wherein at least one of the first and second extractor ports has at least one injection opening positioned on the corresponding slurry passageway.

9. The discharge gate of claim 1 , wherein the first extractor port gradually inclines from an outer surface of the front panel for a predetermined distance at a predetermined angle relative to longitudinal axes of the first extractor port and the front panel.

10. A discharge gate for delivering a mixed slurry from a gypsum slurry mixer, comprising:

a front panel having an elongated pocket disposed on an inner surface of the front panel for receiving the mixed slurry;

a first extractor port extending semi-tangentially from the front panel and being connected in fluid communication with the front panel via a first slurry passageway disposed within the first extractor port for delivering the mixed slurry;

an opening of the first slurry passageway is entirely encircled within the space defined by the pocket when viewed from a side facing an opening of the pocket; and

wherein the elongated pocket begins near one end of the front panel, and ends at an opposite end near an opening of the first slurry passageway.

11. A discharge gate for delivering a mixed slurry from a gypsum slurry mixer, comprising:

an inlet opening in fluid communication with the mixer for receiving said mixed slurry;

a grating fixed in said inlet opening for preventing slurry lumps from passing out the mixer;

a first extractor port disposed on an outlet side of said grating and is configured for generating a first density slurry for a first gypsum layer;

a second extractor port disposed adjacent said first extractor port and also on said outlet side of said grating and is configured for generating a second density slurry for a second gypsum layer;

a channel defined by a front panel and a side panel of the discharge gate for delivering the first and second density slurries from the slurry mixer;

a pocket configured for receiving the mixed slurry is disposed as an elongate recess depressed from an inner surface of the front panel; and

said first extractor port extends semi-tangentially from the front panel of the discharge gate, has an opening located in said pocket and defines a first slurry passageway in fluid connection with said pocket and said channel and said first slimy passageway being disposed within the first extractor port for delivering the first density slurry.
