Abstract
Abstract A continuous duty, fully enclosed apparatus for deagglomerating solid, insoluble particles such as pigments and for uniformly distributing and dispersing the particles in a liquid vehicle which involves the utilization of a dispersing media such as steel shot which is retained in a generally cylindrical mixing vessel and agitated by impellers or agitator discs connected to a drive shaft. The apparatus utilizes a flow disruptor means disposed at the upper end of the apparatus to assist in separating the dispersing media from the processed product and returning the dispersing media to its normal work area.

Total Claims: 8
Claim 1
Independent Claim
208 words
In apparatus for deagglomerating and dispersing solid particles held in agglomerated form and carried in suspension in a liquid vehicle by the action of a dispersing media on the solids the combination comprising: a mixing vessel having a fluid inlet at the bottom thereof and a fluid outlet in the upper portion thereof, said vessel being adapted to have a charge of dispersing media introduced thereinto, said inlet being adapted to be operatively connected to means for introducing a fluid mixture into said inlet and through the dispersing media to said outlet; a rotating shaft extending into said vessel and adapted to be driven from a power source; a rotor separator for separating dispersing media from the fluid mixture, said rotor separator being operatively associated with said shaft to be rotatably driven thereby and disposed in the path of flow between said vessel inlet and outlet; agitating means operatively associated with said shaft within said vessel for agitating the dispersing media; a stationary flow disruptor member disposed at the upper end of said vessel adjacent the mixing vessel wall and surrounding said rotor separator and extending to substantially the uppermost portion of the vessel to prevent concentration of dispersing media in the upper portion of said mixing vessel.

208 words
In apparatus for deagglomerating and dispersing solid particles held in agglomerated form and carried in suspension in a liquid vehicle by the action of a dispersing media on the solids the combination comprising: a mixing vessel having a fluid inlet at the bottom thereof and a fluid outlet in the upper portion thereof, said vessel being adapted to have a charge of dispersing media introduced thereinto, said inlet being adapted to be operatively connected to means for introducing a fluid mixture into said inlet and through the dispersing media to said outlet; a rotating shaft extending into said vessel and adapted to be driven from a power source; a rotor separator for separating dispersing media from the fluid mixture, said rotor separator being operatively associated with said shaft to be rotatably driven thereby and disposed in the path of flow between said vessel inlet and outlet; agitating means operatively associated with said shaft within said vessel for agitating the dispersing media; a stationary flow disruptor member disposed at the upper end of said vessel adjacent the mixing vessel wall and surrounding said rotor separator and extending to substantially the uppermost portion of the vessel to prevent concentration of dispersing media in the upper portion of said mixing vessel.
Claim 3
Dependent Claim
59 words
The combination of claim 1 wherein said flow disruptor member comprises a flat strip attached to the uppermost portion of the mixing vessel and disposed at an angle along the mixing vessel wall in such a manner as to redirect upward movement of dispersing media which impinges against its underside back down into the central portion of the vessel.
Claim 4
Dependent Claim
34 words
The combination of claim 1 wherein said flow disruptor member comprises stationary helicoid means attached to the uppermost portion of the mixing vessel and is disposed closely adjacent the wall of the mixing vessel.
Claim 5
Dependent Claim
33 words
The combination of claim 3 wherein said helicoid means comprises a flat strip formed in a spiral shape the outer edge of which is disposed closely adjacent the wall of the mixing vessel.
Claim 6
Dependent Claim
18 words
The combination of claim 3 wherein said helicoid means comprises a plurality of circumferentially spaced substantially spiral segments.
Claim 7
Dependent Claim
200 words
In apparatus for deagglomerating and dispersing solid particles held in agglomerated form and carried in suspension in a liquid vehicle by the action of a dispersing media on the solids the combination comprising: a mixing vessel having a fluid inlet at the bottom thereof and a fluid outlet in the upper portion thereof, said vessel being adapted to have a charge of dispersing media introduced thereinto, said inlet being adapted to be operatively connected to means for introducing a fluid mixture into said inlet and through the dispersing media to said outlet; a rotating shaft extending into said vessel and adapted to be driven from a power source; a separator for separating dispersing media from the fluid mixture, said separator being operatively associated with said shaft and disposed in the path of flow between said vessel inlet and outlet; agitating means operatively associated with said shaft within said vessel for agitating the dispersing media; stationary helicoid flow disruptor means disposed at the upper end of said vessel adjacent the mixing vessel wall and surrounding said separator and extending to substantially the uppermost portion of said vessel to prevent concentration of dispersing media in the upper portion of said mixing vessel.
Claim 8
