  • Yet another object of the present invention is to provide a transfer mechanism of the type set forth for the Armstrong Process in order to transfer slurry from an inerted vessel or container to a vacuum or inerted chamber for further processing wherein a plug established in the transfer mechanism isolating the vessels or containers.
  • Yet another object of the present invention is to provide a transfer mechanism between a first vessel containing a slurry of liquid and solids and a second vessel with at least one of the first and second vessels being under a protective atmosphere and/or vacuum, comprising a housing in communication with the first and the second vessels, a screw having at least one helical thread along a longitudinal shank within the housing for transferring material from the first vessel to the second vessel, the screw and the housing cooperating to compress the slurry, whereby slurry entering the housing from the first vessel has the solids therein concentrated as the slurry is transported by the screw toward the second vessel while liquid is expressed from the slurry as the solids are concentrated until the concentrated solids form a plug isolating the second vessel from the first vessel while solids discharge into the second vessel.
  • a further object of the invention is to provide a transfer mechanism between a first vessel containing a slurry of liquid alkali or alkaline earth metal or mixtures thereof and metal or alloy or ceramic particles and halide salt particles and a second vessel with at least one of the first and second vessels having a protective atmosphere and/or vacuum therein, comprising a housing in communication with the first and the second vessels, a screw having at least one helical thread along a longitudinal shank within the housing for transferring material from the first vessel to the second vessel, the screw and the housing cooperating to increase the concentration of solids in the slurry between the first and the second vessels until the concentrated particles form a plug isolating the second vessel and the protective atmosphere or vacuum therein from the first vessel and the protective atmosphere or vacuum therein while solids discharge into the second vessel.
  • a final object of the present invention is to provide a method of concentrating and transferring a slurry of a liquid and solids from one container to another while isolating the environments within the containers from each other, comprising providing communication between the containers, transporting slurry from one container toward another container while expressing liquid from the slurry thereby increasing the solids concentration thereof until a plug is formed between two containers isolating same while solids from the plug are transferred to the another container.
  • FIGURE 1 is a schematic illustration showing the two vessels and an embodiment of the transfer mechanism therebetween;
  • FIG. 2 is a schematic illustration of an alternate embodiment of the present invention;
  • FIG. 3 is a schematic illustration of yet another embodiment of the present invention;
  • FIG. 4 is a schematic illustration of a further embodiment of the present invention.
  • a transfer mechanism 10 which includes a double walled conduit including an outer conduit wall 11 having a liquid outlet 12 and end walls 13, the wall 11 being preferably but not necessarily cylindrical. Interior of the cylindrical wall 11 is an inner tube or conduit 15 having a portion 16 which is solid and a portion 17 which is apertured and may be a mesh of any suitable size.
  • the inner tube or conduit 15 may either be cylindrical as illustrated in Fig. 1 or conical as will be explained, the inner conduit 15 has a discharge end 18 thereof which opens into a vacuum chamber 25 and has an inlet end 19 thereof which opens into a container or vessel 20 in communication with the reactor as illustrated in the Armstrong patents previously referenced and incorporated herein.
  • a feed screw 30 is positioned within the inner conduit 15 and includes a rotatable shank 31 having a helical thread 32 positioned on the shank 31 as is well known in the art.
  • the thread 32 may have a constant or a variable pitch.
  • the pitch is the distance between adjacent threads and the variable pitch may preferably be a progressive pitch in which the pitch decreases from the vessel 20 toward the container or vessel 25, for a purpose hereinafter described.
  • the transfer mechanism 10 is used in conjunction with a material made by the Armstrong Process. More particularly, for purposes of illustration only, the slurry discussed herein will be a combination of liquid sodium, sodium chloride particles and particles of titanium and/or a titanium alloy.
  • the vessel or container 20 preferably operated under an inert atmosphere or under vacuum has therein a slurry of the particles previously described and as the slurry enters the portion 19 of the inner conduit or tube 15 and the feed screw 30 is rotated as illustrated in the drawings by rotation of the shank 31 , the slurry is moved along the feed screw from left to right as illustrated in Fig. 1. Because of the progressive pitch of the feed screw 30 in Fig.
  • a seal by the transfer mechanism 10 is a critical aspect of the present invention because separation of liquid sodium and salt from the desired particles of the ceramic or metal alloy, as described in the Armstrong patents may include distillation in a vacuum chamber or a vessel 25 or removal of the liquid metal by vaporization with a hot inert sweep gas and the Armstrong reactor itself may be an inerted vessel such as with argon. Accordingly, it is important for a seal or plug to be formed between the two containers or vessels in order to •permit continuous operation between the two vessels without the necessity of shutting down one of the vessels during transfer or destroying the protective atmosphere in the vessel 20 or the vacuum or protective atmosphere in vessel 25. Referring to Figs. 2 and 3, there are disclosed alternate embodiments of the invention.
  • the transfer mechanism 10A has a housing 15A conical in shape and the screw 30 therein may or may not be a progressive pitch screw.
  • the screw threads in the embodiment illustrated in Fig.2 may not need to be closer together, that is the pitch need not be diminished in order to reduce the volume of the material between adjacent threads and the housing wall as the material is moved from left to right or from vessel 20A to vessel 25A.
  • FIG. 3 there is shown another embodiment of the present invention in which the shank 31 B of the screw 30B is conical in shape with the larger end of the cone being adjacent the vessel 25B and with the pitch between adjacent threads 32B being constant or diminishing. In either case, the volume of the area between adjacent threads and the inner container 15B diminishes as the material is moved from the vessel 20B to the vessel 25B.
  • Fig. 4 there is shown a further embodiment 10C of the present invention in which a cylinder 15C interconnects vessels 20C and 25C and transports slurry while concentrating same between the two vessels. Slurry entering the inlet 19C of the cylinder 15C is concentrated upon rotation of screw 30C due to movement of the helical thread 32C upon rotation of the shaft 31 C.
  • the outlet end 18C of cylinder 15C is an apertured plate having an effective diameter smaller than the inlet 19C thereby restricting flow of the slurry causing in cooperation with the screw 30C and housing or cylinder 15C the solids in the slurry to concentrate while liquid is expressed from the slurry and is separated therefrom through outlet or drain 12C.
  • a plug is formed which isolates, as hereinbefore explained, vessel 20 from vessel 25, thereby permitting the continuous production of slurry in vessel 20, or a vessel or container in communication therewith, and continuous separation of solids, even if wet with liquid, by the transfer mechanism 10C in vessel 25 or a vessel in communication therewith for further treatment in the same or different environment as vessel 20.
  • separation of Na and/or NaCI from Ti or Ti alloy powder in vessel 25 may be accomplished by distillation and/or by a hot inert sweep gas followed by passivation and/or washing the water.
  • a hot inert sweep gas followed by passivation and/or washing the water.
  • liquid Na may be present at about 60% by weight of the slurry leaving vessel 20, while the wet solids discharged into vessel 25 may have Na present only in the range of from about 20 to about 50% by weight.
  • the invention includes movement and concentration of material from one container to another without compromising the environment of either container.
  • the containers may be connected pipes or vessels, and the environments may be vacuums, inerted atmospheres or otherwise.
  • Concentration of solids in a slurry to transport solids from one environment to another while forming a seal or plug therebetween so as to isolate the environments from each other.
