Definitions

  • the invention relates to an installation for washing inert materials such as sand, gravel or the like.
  • bucket installations consisting of a semi-cylindrical tank containing the inert material and the washing liquid: the buckets, fixed radially to a central shaft, catch, mix and lift the material while leaving the liquid wash through the specially provided holes in the cups and discharging the washed inert material into the adjacent compartments.
  • the object of the present invention is to propose an installation for washing inert materials, such as sand, gravel or similar materials, eliminating or greatly reducing these drawbacks.
  • each rotor is provided with annular transverse diaphragms delimiting annular channels; each channel comprises several buckets at its periphery, the bottom of which is provided with holes and the lifting of which is inclined relative to the shaft so that, when the rotors rotate, the washing liquid present in each rotor overflows outside the lowest diaphragm of each rotor, and so that the inert material to be washed, introduced by the mouth of the rotor located at one end of the installation, advances against the current passing through all the rotors before being discharged through the orifice of the ro tor located at the other end of the installation.
  • the advantages obtained thanks to this invention consist essentially in that it is possible to wash inert materials of any size even if very dirty; in that the consumption of washing liquid and motive energy is much lower than that of installations of known type, even compared to the quantity of washed material produced; in that the installation has a longer service life and in that it requires only reduced maintenance.
  • Figure 1 is the longitudinal section of a first embodiment according to the invention
  • Figure 2 is the longitudinal section of a second embodiment
  • 3 shows the installation of Figures 1 and 2, in front view of the outlet side of the washed inert and in partial section
  • FIG. 4 is a variant of FIG. 3.
  • FIG. 3 of the accompanying drawings several rollers (12) have been provided to serve as a support and to rotate the rotors (1).
  • a pipe (7) for supplying washing liquid passes, preferably axially, through the rotors and is provided with several outlets (8) for outlet of the washing liquid (9).
  • the embodiment of Figure 1 provides a mouth (8) per rotor (1).
  • Dirty inert material supply devices (10) located opposite the lower end of the installation and which are constituted either by a conveyor belt (11) either by a hopper or the like.
  • each rotor (1) is provided with several intermediate annular diaphragms (2a) delimiting several annular channels (3).
  • the washing liquid supply pipe (7) has a drainage mouth (8) only opposite the upper annular channel (3) of each rotor (1) while the channels (3) of each rotor located below the first are filled with water overflowing from the corresponding upper channel.
  • FIGS 3 and 4 of the accompanying drawings show the arrangement of the buckets (15) according to two possible orientations, namely in radial position and inclined relative to the radius of the rotor (1); in any case, the washed inert material is discharged into the adjacent annular channel (3) situated above it due to the rotation of the rotor (1).
  • the inert material to be washed is brought in front of the lower annular channel or channels (3) of the lower end of the installation and the supply pipe (7) supplies the washing liquid which fills the lowest area of each channel (3) to the edge of the lower diaphragm (2) from where it flows outside or into the adjacent channel (3) located below.
  • the water or washing liquid supplied continuously and in small quantities through the hose (7) flows downward, entailing the impurities removed from the inert material.
