  • Patent number: 4404173
    Abstract: An improved method and apparatus for producing a dispersion of substantially immiscible liquids which employs a conduit having an upstream section divided into first and second channels of variable length and a downstream section for mixing the liquids. The apparatus also includes means for varying the length of the first and second channels and means for flowing the liquids separately through the channels whereby the liquids mix in the downstream section of the conduit to form the dispersion. In accordance with one embodiment, a conventional mixer-settler is modified to include the conduit mounted at an upstream end of the settling chamber so that its inlet is adjacent the mixing chamber and its outlet is approximately at the same height as the organic-aqueous interface in the settling chamber.

  • Patent number: 4398828
    Abstract: The invention relates to a pneumatic mixing silo comprising a storage compartment, a central mixing compartment connected thereto and at least one material inlet opening into the mixing compartment and at least one material outlet connected to the mixing compartment. A considerable improvement in the mixing effect of this mixing silo (1) may be obtained above all if the material outlet (14) is formed by an overflow from the mixing compartment (3). In addition, correcting material may be directly introduced into the mixing compartment through an additional material inlet (12).

  • Patent number: 4395131
    Abstract: The present invention relates to an apparatus for agitating, conveying and weighing particulate material. An agitator is provided including a generally cylindrical housing having end walls with bearings in them. An agitator is provided in the housing, including a pair of end members having openings therein; stub shafts are supported by shaft hangers and extend through the end wall bearings and the end members, for ready removal, axially, permitting removal of the agitator in a radial direction through an opening in the housing. A screw conveyor beneath the agitator has a housing removably connected to the agitator housing. A single direct current drive motor is provided, connected by sprockets and chains to the agitator shaft and to the shaft of the screw conveyor.

  • Patent number: 4350444
    Abstract: An apparatus for mixing materials is disclosed. The apparatus includes a hopper, a substantially vertical auger within the hopper, and a housing enclosing the auger to define a mixing chamber. A baffle, attached to the housing, and the sidewall of the hopper are oriented so as to cooperatively provide a blending flow pattern within the hopper, thereby further mixing the materials.

  • Patent number: 4347003
    Abstract: A two-stage extruder having a first, vertical stage and a second, separately driven, horizontal stage, the two stages being off-set from one another and lying at tangents to one another in the region of a connecting passage. The first stage has a rotatable plasticizing member with kneading blades off-set from one another and located between conveying screw components of said member and cylindrical pins projecting into the working chamber of said first stage. A bearing is provided for the member at its upper end and a cylindrical sleeve surrounds the lower end of the member and can be turned to control the effective size of the connecting passage or to eject material through a second outlet.

  • Patent number: 4332484
    Abstract: A manure agitation system directed to an open top tank for storage of manure slurry. A gate valve is located in the floor of the tank which can be opened from outside the tank to draw manure slurry from the inside of the tank through a piping system and pump assembly and flow it under pressure through the piping system to an agitator nozzle for substantially high pressure discharge and located inside the tank generally centrally of the floor of the tank and which can be rotated to different positions from outside the tank. A pair of first and second flow control valves are opened to permit the flow of the manure slurry as described and a third control valve is then in closed position.

  • Patent number: 4282989
    Abstract: A device for feeding or pressing plastics material to an extruder includes a conically shaped housing with its apex directed downwardly and with a similarly conically shaped feeding member within the housing. The outer surface of the feeding member is parallel to and spaced inwardly from the inner surface of the housing. A screw blade is secured to and extends helically around the outer surface of the feed member. A partition wall divides the interior of the housing into an upper storage chamber and a lower material conveying chamber. The partition wall is constructed to provide variable openings for admitting material from the storage chamber into the conveying chamber.

  • Patent number: 4205919
    Abstract: A mixer especially for mixing materials such as cement and sand with water and with a fibrous reinforcing material such as glass fibre. The mixer consists of a tubular casing containing a skeletal rotor constructed from a plurality of rods extending longitudinally of the casing and spaced apart laterally of each other at positions circumferentially spaced apart around the axis of rotation of the rotor and the longitudinal axis of the casing. The rods are supported on end plates and a central shaft or stub shafts extending from the end plates. The rods are enveloped along at least part of the axial length of the rotor by a helical, outwardly-directed flight having widely-spaced convolutions to impart a component of movement to the mix along the inside of the tubular casing to an outlet.
