Abstract

DC60 (17/08/47) This invention provides a mixer and blending method capable of delivering slurry delivery. Consistent at high flow rates Where the foam is evenly mixed The mixer (10) has the chamber (20), the rotary plate (32) the slurry outlet, (45) the steer delivery pipe. The oval (46) and the hollow connector section (47) the foam feeding port (41) are positioned so that Pre-set on the annular wall or on the hollow connector section, the foam feeding cavity will feed the foam to the steamer. Immediately before Serry flows into Slurry outlet or styrofoam feeder in the body part Connect the hollow, slurry, and the foam is mixed together at the funnel. Out of slurry or on the destination side The foam will not be made. Is subjected to impact due to agitation in the mixer and the foam loss is reduced The foam will be mixed with slurry. Even if the flow rate is increased, and therefore the gypsum board production rate can be increased, the invention provides a mixer and mixing method that can deliver slurry efficiently.

R4. Mixers, as set out in any of Claims 1 to 3, where the outlet of Slerry will cause The gypsum litters flow into the hollow connector section as Say in a direction 5. Mixers as set out in claim 3, where the long strait is formed. It is supplied by such propellers with thickness (t) in the range from 1 mm to 5 mm, which are Manage it in the equilibrium and dimensions (h, w) of the long straits. The propellers are set in the range from 4 mm to 15 mm. 6. Mixers as set out in either Clause 3 or 5, where such propellers are Get organized in Horizontal or vertical position 7. Mixers as defined in Claims 1 to 6, where the link The hollow joints have wall surfaces (47a, 47b) on the source and destination sides in the direction of rotation. Lerry in that section And the aforementioned wall surfaces (47a) on the source side were positioned at an angle ranging from 90 ํ to 120 ํ relative to the normal (G) line of the chamber. Set out in claim 7, where the foam feeding port is Placement on such wall surface (47a) on the source side 9. Mixers as set out in claim 7 or 8, any one where such wall surfaces (47a, 47b) will be parallel. 1 0. The mixer, as defined in any Clause 7 to 9, where such a wall surface (47b) on the end end is positioned at an acute angle relative to the floor. Inner surface along Such circumference to prevent The slurry of gypsum through the slurry flows backward or back into the chamber 1 1. Mixers as defined in claim 2, where the hollow coupling part. have Get connected To the pipe of the slerry to cause the slur. The oval of the gypsum flows into the area. Within the direction of contact 1 2. Mixers as specified in Clause 2 or 11, where the body part Such hollow connections Has been connected to the said slurry delivery pipe in Eccentric position Therefore, the gypsum slurry in the interior area rotates in the opposite direction to the rotation direction of the plate. Claim 2 or 11, any one where the part is Such hollow connections Has been connected to the said slurry delivery pipe in Eccentric position Thus, the gypsum slurry in the interior area rotates in the same direction as the rotational direction of the plate.
