Definitions

  • ABSTRACT In a hydrocyclone arrangement at least two hydrocyclones are spaced laterally apart with a filling chamber, an overflow chamber and an underflow chamber arranged centrically of the hydrocyclones.
  • the filling chamber is aligned above the overflow chamber and the underflow chamber is aligned below the overflow chamber.
  • the hydrocyclones are disposed obliquely of the vertical so that the underflow from each is directed into the underflow chamber.
  • the filling chamber has a spherical configuration and a separate connection extends radially outwardly from the filling chamber to each of the hydrocyclones.
  • a supply connection extends vertically upwardly into the filling chamber passing vertically through the overflow chamber and then extending horizontally outwardly or continuing to proceed vertically through the underflow chamber.
  • Replaceable wear protection parts are positioned in the filling chamber and the filling chamber is constructed so that it can be opened for access to the wear protection parts. Further, the wear protection parts can be arranged to form enclosed wear indication spaces within the filling chamber connected through a tubular member with the outside atmosphere.
  • Each of the filling chamber, overflow chamber and underflow chamber can be divided in two by vertical partitions for forming independent functional groups of the separate chambers each associated with a different hydrocyclone.
  • the present invention is directed to a hydrocyclone arrangement including two or more hydrocyclones and, more particularly, it concerns the arrangement of a common filling chamber, a common overflow chamber and a common underflow chamber disposed in vertical alignment and spaced centrically of the hydrocyclones. Further, the hydrocyclones are oriented at an angle to the vertical so that underflow from the hydrocyclones is directed into the underflow chamber located below the filling chamber and the overflow chamber.
  • the filling chamber is positioned below the overflow chamber and, as a result the overflow extends over a relatively great height and the total pressure in the plant is very high. Further, the connections from the filling chamber to the hydrocyclones must be curved which, from a construction point of view, is expensive and results in increased wear.
  • the primary object of the present invention is to afford an improved hydrocyclone arrangement which is less expensive to manufacture and avoids the difficulties previously experienced.
  • the filling chamber is located above the overflow chamber and the connections between the filling chamber and the hydrocyclones extend rectilinearly between the two of them.
  • the overflow chamber located below the filling chamber the energy required for pumping the overflow and the necessary pressure are very low. Further, the overall height of the hydrocyclone arrangement is reduced, since the filling, overflow and underflow chambers can be directly superposed and dead space between them is avoided.
  • the filling chamber can be formed of a spherical body so that the connections to the hydrocyclones extend radially outwardly in a rectilinear manner so that wear-causing bends are avoided.
  • the hydrocyclone arrangement affords a very compact construction which is inexpensive to produce and is rugged in operation.

  • FIG. 2 is a view similar to FIG. 1 showing another embodiment of a hydrocyclone arrangement in accordance with the present invention
  • FIGS. 3 to 6 schematically represent four possible embodiments of a filling chamber for use in the hydrocyclone arrangement of the present invention
  • FIG. 7 is a schematic representation of a hydrocyclone arrangement in accordance with the present invention sub-divided into two functional groups.
  • FIG. 8 is a schematic representation of another embodiment of a filling chamber which can be used in the hydrocyclone arrangement of the present invention.

  • the filling chamber 1 is spherically shaped and connections 3, 4 extend radially outwardly in a rectilinear manner from the filling chamber to the upper ends of the hydrocyclones 5, 6.
  • Overflow bends 7, 8 extend from each of the hydrocyclones into the upper end of the overflow chamber.
  • the overflow chamber 1 is spherical in shape, as mentioned above, and is formed of two parts for gaining access to its interior.
  • the supply connection 9 extends vertically downwardly through both the overflow chamber 2 and the underflow chamber 11 and, as a result, the underflow chamber has its outlets located laterally about the supply connection 9.
  • the outlet from the underflow chamber 11 is located centrally.
  • the supply connection 9 it is also possible for the supply connection 9 to enter the filling chamber at its top and, in such an arrangement, the overflow chamber 2 and the underflow chamber 11 are free of any restrictions.
  • FIG. 3 an arrangement is shown for the degasification of the filling chamber 1 which can be easily effected during operation.
  • a collecting chamber 13 for gases or air which communicates with the interior of the filling chamber through an opening 14.
  • a transparent control indicator tube 15 Spaced from the collecting chamber 13 and in communication with and extending upwardly from the filling chamber is a transparent control indicator tube 15.
  • a valved connection 16 joins it to the collecting chamber 13 and provides an exhaust for gas or air.
  • Another feature of the invention is the arrangement of the filling chamber 1 for affording the installation of replaceable wear protection parts.
  • a hemispherically shaped wear protection part 17 is supported in the upper half of the spherically shaped filling chamber 1 by means of supporting bolts 18.

  • a wear indication assembly which consists of the hemispherically shaped wear protection part 17 and an additional arcuately shaped plate 21 joined to the wear protection part 17 and located between it and the inner surface of the filling chamber 1.
  • the wear protection part 17 and the plate 21 combine to form a space 22 to which a sealed pipe 23 is connected and extends outwardly from the filling chamber so that the space 22 is in pressure-free communication with the outside atmosphere.
  • the filling chamber is formed of two parts or is provided with a removable cover for affording access to its inter- IOI'.
  • the wear protection part 17 and the wear plate 20 can be held within the filling chamber 1 in the manner shown in FIG. 6 where the wear protection part 17 has an annular flange-44 extending into the joint 45 or between the connecting flanges 46 of the two halves of the filling chamber and forming a sealed space 22 between the wear protection part 17 and the inner surface of the chamber 1.
  • a wear indicator is provided for observing any leakage into the space 22.
  • the wear plate 20 is supported from the wear protection part 17 by means of an arcuately or cup-shaped member 20' and a tubular member 23" which affords pressure equalization between space 22' formed between the plate 20 and the member 20 and the space 22.
