Apparatus for the integral sprinkling of liquids laden with solid materials in suspension

Apparatus for the integral sprinkling of liquids laden with solid materials of appropriate granulometry in suspension and contained in a vat having a central chimney, with the liquid contained in the vat, comprising:

• return pipe means for returning liquid which has been taken from the vat, back to the vat with a substantially constant diffusion pressure, said return pipe means having a substantially constant cross-sectional diameter and a lower end through which the liquid is returned back to the vat;
• diffusion cone means for diffusing the liquid returned to the vat by said return pipe means, said diffusion cone means being movable with respect to the lower end of said return pipe means, in an axial direction of said return pipe means;
• rotary cam means for variably and repeatedly moving said diffusion cone means in predetermined cycles of movement, in the axial direction of said return pipe means;
• and
• motor means for driving said rotary cam means, such that said rotary cam means causes said diffusion cone means to uniformly distribute a quantity of said liquid at any point in the vat.

Apparatus for the integral sprinkling of liquids laden with solid materials of appropriate granulometry in suspension and contained in a vat having an off-central chimney, with the liquid contained in the vat, comprising:

• return pipe means for returning liquid which has been taken from the vat, back to the vat with a substantially constant diffusion pressure, said return pipe means having a substantially constant cross-sectional diameter and a lower end through which the liquid is returned back to the vat;
• flap valve means for diffusing the liquid returned to the vat by said return pipe means, said flap valve means being pivotally connected to the lower end of said return pipe means about a pivot point;
• and
• moving means for:
• repeatedly oscillating said flap valve means about said pivot point in predetermined cycles of movement with respect to said return pipe means, and
• varying the times that the flap valve means remains at different positions relative to the return pipe means during each cycle, to cause said flap valve means to variably open and close the lower end of said return pipe means,
• so as to diffuse a substantially constant quantity of liquid at any surface position of the vat.
