Title: Improvements in apparatus for the formation and separation of solids from liquids or gases by heat interchange
IPC: F25C1/12
Filed: 1923-04-04
Abstract: 219,062. Field, C. April 4, 1923. Impuritics, separating from gases.-Ice or other crystals are obtained in the form of small particles from liquids or gases by depositing a thin layer of the solid on a continuously rotating flexible cylinder 14, Figs. 1 and 6, cooled internally, the wall of the cyinder being distorted mechanically at different parts to detach and breakup the layer. The cylinder 14 is preferably of metal and its ends may be slidably mounted in stuffing- boxes 13 in members 10 rotatably mounted on a fixed shaft 9 through which brine or other cooling- medium is supplied and withdrawn. The members 10 are driven from a power shaft 34 through toothed gearing 32, 36. Upon the shaft 9 are mounted arms 23 carrying rollers 24 at a greater distance apart than the normal diameter of the cylinder, whereby the cylinder is distorted during its rotation. Liquid is supplied to the tank 5 in which the cylinder is mounted through an opening 27 or 29 according to its density, and floating solids are removed by a conveyor 31, Fig. 6, while heavy solids are removed by a screw conveyer 38, Fig. 1. Where gases are treated for the recovery of solidifiable constituents they are withdrawn by a flue 40, Fig. 1. In a modification, the end of the cylinder 14 may be fitted within an inflatable tube 41, Fig. 2, to obtain a yielding fluid-tight joint with the member 10, contact being maintained by rollers 45; or the cylinder may fit over an inflatable tube, contact being maintained by an external roller. In a further arrangement, the end member 10 may support two inflatable tubes 59, Fig. 7, a flexible ring 60 being interposed between these tubes and the end of the cylinder 14. In this case distortion is produced by spring-pressed rollers 63 on a lever carried by a radial arm 66. The cylinder may be contracted at its end, as shown in Fig. 4, and attached to a driven sleeve 49, distortion being produced by a roller 54 bearing on a rubber ring 51 or on an inflated tube 52. To facilitate the detachment of the solid, the liquid in the tank may be forced by a pump through nozzles directed against the surface of the cylinder. In a further arrangement, shown in Fig. 10, the cylinder is mounted in the open. the liquid being forced on to the surface from a pressure chamber 73 through nozzles 74. The detached particles are directed away from the nozzles by a baffle 77 and removed by a conveyar 78.
