Abstract
To provide a dispersing apparatus that can stir media in a vessel uniformly, and by increasing the shearing power at stirring, can perform quality constant dispersion with high dispersing efficiency. In a dispersing apparatus wherein a basket-shaped vessel 2 containing dispersing medium consisting of ceramic balls, zirconia balls, and the like is submerged in a tank 8 filled with a compound, and stirrer vanes 28 are rotated in the above vessel to stir the above dispersing medium, and the compound that goes through the inside of the above vessel 2 is dispersed, a rotation driving mechanism 11 for rotating the above vessel 2 in the opposite direction to the above stirrer components.
Claims11
A compound dispersing apparatus comprising:
- a basket-shaped vessel, said vessel containing dispersing media particles in an interior cavity formed therein, said vessel submergible in a tank filled with a compound;
- a plurality of plate shaped stirrer vanes housed within said vessel, each engaged at first ends with an elongated at first ends with an elongated shaft extending in said interior cavity, said shaft defining a central axis of said cavity;
- each said stirrer vane extending a first distance from said axis to a distal edge;
- means to rotate said shaft to thereby rotate said stirrer vanes in said interior cavity;
- a plurality of plate shaped stirrer fins, each engaged at a first end with an interior wall of said vessel, each said stirrer fins extending from said first end toward said central axis, to a distal end;
- each of said stirrer fins positioned in its engagement with said interior wall whereby said distal end reaches a momentary substantial alignment with a corresponding said distal edge of one of said stirrer vanes during each rotation of said shaft;
- a gap-formed between said distal end and said distal edge during said momentary alignment, said gap defined by an empty space bordered on a first side by said distal end and on a second side a second distance from said first side, by said distal edge;
- said gap providing means to increase a shear force of said dispersing media particles during said momentary alignment, and
- whereby said compound in said tank is drawn through said interior cavity and existed back to said tank by rotation of said vanes when said vessel is submerged in said tank.
