摘要： Novel and improved methods and apparatus for processing liquid or viscous materials. Essentially, the methods and apparatus involve feeding liquid materials to an annular processing passage for controlled processing. The annular processing passage is provided by two elements. One is a rotatable element carrying at least one processing channel. The other element is stationary and provides a complementary coaxial surface arranged with the channel to provide the enclosed processing passage. Also associated with the stationary element are an inlet for feeding material to the passage, an outlet for discharging material from the passage, an element near the outlet providing a material collecting end wall surface and an element positioned between the inlet and outlet providing a liquid material spreading surface. Rotation of the rotatable element toward the spreading surface provides a coaction between the rotatable element and the spreading surface so that relative movement is established between the rotating inner channel walls and liquid material between the inlet and the spreader surface. Because of the relative movement, the liquid material is spread toward the walls and dragged by the walls through a clearance between the sides of the spreading surface providing member and the side walls as thin layers providing central spaces of the passage downstream of the spreader surface which are free of liquid material. Means are arranged for communicating with the free central spaces to add materials to or withdraw materials from the free central space.

摘要： A rotary processor for high-shear processing of plastic or polymeric materials comprises a rotor having end discs and at least one mixing disc therebetween, the rotor closely surrounded by a housing to defined annular processing chambers flanking each mixing disc, with a high-shear-mixing transfer gap defined between the mixing disc and the housing. Channel blocks are deployed at circumferentially spaced apart positions in adjacent chambers to cause transfer of material through the transfer gaps, with dispersive mixing occurring in the transfer gaps. Some embodiments have plural channel blocks in the chambers, evenly spaced apart. The channel blocks extend generally into and to the bottom of a chamber, and have two working surfaces divergent from a central region of the chamber and convergent toward the disc walls defining the chamber. The working surfaces and disc walls defined two high-shear-mixing recycle gaps through which a portion of the material passes and is mixed. The channel block configuration is also used in a single chamber rotary processor.

摘要： Novel rotary processors and devolatilizing methods which provide extremely efficient devolatilization of materials, including viscous and visco-elastic materials and which involve a devolatilizing stage including a rotatable element carrying a plurality of annular channels and a stationary element providing a coaxial closure surface operationally arranged with the channels to provide enclosed processing passages. Each passage of the devolatilizing stage includes inlet means, outlet means and a channel blocking member all associated with the stationary element and arranged and adapted so that material fed to the inlet can be carried forward by the rotatable channel walls to the blocking member for discharge from the passage. The passages are interconnected by material to transfer grooves formed in the closure surface and operationally communicate with a vacuum source to provide a highly efficient devolatilizing stage.The novel devolatilizing stage is characterized by features which provide control of the processing volume available within the passages and of the transfer volume available within the transfer grooves. These volumes may then be coordinated with other processing variables to effect a foam devolatilizing mechanism in which nucleation of bubbles of volatiles within the material, bubble growth and bubble rupture occur during substantially plug-flow movement alternating with non-pressurizing shearing within the novel devolatilizing stage.

摘要： Novel, improved rotary processors which include a rotatable element carrying a plurality of annular channels and a stationary element providing a coaxial, closure surface operationally arranged with the channels to provide enclosed processing passages. The so-formed plurality of processing passages provide a highly efficient processing stage particularly for melting polymer material. Each processing passage of the processing stage includes inlet means, outlet means and a channel member associated with the stationary element and arranged and adapted so that material fed to the inlet can be carried forward by the rotatable channel walls to the blocking member for discharge from the passage.In rotary processors of this invention the clearance between the rotary surface carrying the channels and the stationary coaxial closure surface is relatively wide and permits substantial amounts of material to be interchanged between passages of the processing stage. The interchange provides especially efficient, intensive mixing for material processed in the stage. Also, the interchanged material which passes through the relatively wide clearance can be subjected to conditions of high shear and high temperatures.

摘要： Sealing means for controlling leakage of material between closely spaced apart, relatively moving coaxial annular surfaces. Essentially, leakage is controlled by providing a pumping channel on one of the surfaces and a leakage liquid retaining channel on the other surface. The pumping and leakage liquid retaining channels are cooperatively arranged to resist flow of leakage liquid between the surfaces. The sealing means are particularly adaptable for controlling leakage from processing passages of rotary processing apparatus.
