Definitions

  • the device is based on the principle of separating by centrifugal action a heavier liquid, such as water and also foreign materials of higher specific gravity from the inflammable liquid having a lower specific gravity.
  • the present invention mainly consists in a centrifugal separating device for a mixture of a heavier liquid of a lighter liquid, and comprises, in combination, an elongated rotary drum having an outwardly located wall portion formed with at least one opening; inlet means for a mixture of a heavier liquid and a lighter liquid located at one end of the drum in the region of the.
  • closure means or valves actuated by iloater means which have a specific gravity lower than that of the water to be eliminated, but higher than that of the liquid to be depui-ated.
  • the device provides filter means formed by an annular diaphragm arranged before the outlet. The outlet opening can be throttled and if necessary closed by means of a gear automatically driven by the iloats, so as to prevent discharge of the water together with the liquid to be depurated, which could occur in ICC the caseof a water excess in the device, which excess would not be able to ow off through the valves.
  • a certain amount of water is placed in the device before the start of the operation.
  • Fig. l a longitudinal section
  • Fig. 2 is a cross section of a first embodiment of the device according to the invention taken on line 2-2 in Fig. l;
  • Figs. 3 and 4 are a longitudinal section and a top view respectively, of the detail of a oat and its associated valve on an enlarged scale, and
  • Fig. 5 is a longitudinal section of a device according to another embodiment of the invention.
  • the device includes a case 1 of nearly cylindrical form and rigidly mounted upon a base 2, Wherefrom the standards 3, 3 extend upwardly and serve as bearing frames for the supports 4, 4 with ball bearings S, 5.
  • the supports carry the ends of the hollow tubular shaft 6, revolving around its own axis and passing longitudinally through the case 1.
  • the rotation of the shaft 6 is obtained by means of the grooved pulley 7 ⁇ vhich is connected to shaft for rotation therewith and constitutes a drive means.
  • the ends of shaft 6 are Huid-tightly connected at one side with the connection pipe section 8 of the liquid to be depurated and at the other side with the connection pipe section 9 of the depurated liquid.
  • a drum ftxedly secured to the shaft 6 is arranged in the case l so as to be able to rotate therein, said drum being formed by a cylindrical part 1l), by two frusto conical parts il, i?. and by a part 13 having the shape of a trunh cated cone, all parts being rigidly connected to each other by screws i4 and welding spots l5.
  • the shaft is provided, at the inlet in the aforesaid casing, with inlet means namely four slots 16 having a total area which is much greater than the inner cross-section of the shaft itself, and through which passes the liquid to be depurated,
  • a transverse partition such as the plug 17 is arranged at the end of said slots 16 and in the interior of the shaft 6, and by closing the direct passage through the shaft, it forces the liquid to ow olf through the slots 16.
  • a transverse dellecting means 18 is arranged at the external part of the shaft 6 and serves to guide the liquid.
  • the deecte ing means l rotate together vwith the blades 19 and with the shaft 6, and thus the heavier foreign substances will assemble in the four chambers formed by the cylindrical part le of the drum and by part 13, passing-through the openings 20 in the part l0. These chambers are provided with plugs 21 for carrying out the removal of the foreign substances assembled therein.
  • the annular wall 22 bounding the chambers is extended towards the shaft 6 at 22' so as to form a partition in order to better hold back the foreign substances. Toythe ends of said exten sion 22 are connected the supports 23 of the guiding arms of the floater means 25 joined thereto and freely movable in the direction of the radius of the cylindrical casing 1l).
  • a rod 2S provided at its upper part with a slot in which the arm 29 of the twoarmed-lever 29, 3i) slides, said lever being pivoted in 31 to the support 32 which is also secured to the cylindrical casing l0.
  • rl ⁇ he other arm 30 slides in a similar slot in the support 33 serving to guide the slidable closure means 34, which, being actuated by the floats 25 through motion transmitting means 2S, 29, 30, may throttle or close the slots 3S constituting outlet means in the shaft 6.
  • valves 26 for discharging the water' and ofi-the' floater means 25 are as follows:
  • valves 26 are normally closed while Vthey open whenytogether with the liquid, water has entered, which, being projected against the wall in consequence of the centrifugal eifect to which the liquid to be depurated is subjected, reaches such a volume as to cause'actuation of the floats 25 and hence of the valves.
  • a plug valve or second closure means 36 is arranged in proximity of the outlet slots 35 and is connected to a spiralrspring 37, a lever 38 being secured to the end of said spring.
  • the arms 39, 40 are pivoted to Ysaid lever and are further pivoted to other two arms41, 42 provided with counter weights 43 and 44 respectively, and secured to the fastening ring 45 connected to theshutter 18.
  • the closure Vvalve 36 starts to operate when the device stands still or runs only at a reducedV rotary speed.4
  • the spring 37 maintains closed the valve 36,V hindering the discharge through the slots 35, while, as soon as the centrifugal force of the counter'weights overcomes'the resistance of the spring 37, and havingV been reached the minimum turn number of the device, the linked lever means formed by the arms 39, 40, 41, 42 exerts a return action on the valve 36, which clears the slots 35. ⁇
