Title: Improvements in apparatus for purifying liquids, centrifugally
IPC: B01D17/02
Filed: 1926-12-11
Abstract: 267,858. Alexander, W. Dec. 11, 1926. Density separators.-A vortex type separator used as a liquid purifier has a chamber of circular cross-section with an axial outlet for oil or impurities, and an inclined entry passage to promote a rotary motion in the mixture as it enters the chamber. In the form shown in Fig. 1 the mixture is conveyed to the apparatus by the pipe 1 and passes into the separator chamber 2 through the annular space provided with inclined vanes 3. The water passes out through the annular outlet 5, which may be vaned, and the oil and light impurities are thrown by the vortical movement to the centre. The oil outlet 8 passes through the centre of the top cover and is connected to the pipe 9; an annular baffle 17 is fixed round the outlet 8 to prevent oil from spreading outwards when the flow of the mixture stops. To counteract the drag of the water on the oil particles the fixed vanes 12 are arranged to impress an upward component on the liquid as it rotates round them. In the modification shown in Fig. 2. the entry pipe 4 and water exit pipe 6 are inclined to assist the rotation of the liquid. The oil outlet 8 has fixed vanes and the discharge pipe 9 passes through the bottom of the separator. The fixed vanes 12 are replaced by the annular guide 13. In another modification the water outlet is an annular space at the periphery of the base, and the wall of the chamber is conical at its lower end.

Conductor plates 33 are bolted to metal pads 32 on the section 13, and metal plates 31 welded to the shell ensure good contact with the carbon mass. The upper electrodes consist of a number of carbon cylinders 34 adjustably secured to conductors 37 carried by a framework 38, by means of metal rods 35 provided with clamps 36. When the cell is to be used for refining aluminium, a mixture containing aluminium, sodium and barium chlorides, or a mixture of cryolite and fluor-spar in equal proportions, is placed in the cell and fused to form a crust over the joint between the sections. Molten alloy of the kind to .be used as the anode is then poured into the cell, the fluorides being lighter rising to the top and forming a layer thereon, with the subsequent formation of a crust on the sides of the upper section 13. Part of the fluoride bath is then dipped out and a layer of pure aluminium is poured on the top of the remaining bath mixture to form the cathode. Tap-holes are arranged at the top and bottom of the cell for removing the refined aluminium and the impoverished anode alloy. Fresh alloy may be added by inserting a heated carbon funnel into the cell and pouring the alloy therethrough after the refined metal therein has been removed. In some cases, air may be used as the cooling medium in the jackets instead of water.
