Dosing device and dosing equipment

Dosing device (1) for dosing predetermined quantities of fluids to be dosed comprising liquid products, liquid phase dispersions and solvents, said device (1) comprising a supporting structure (10), defining a main axis (1a), a first end (10a) and a second end (10b) opposite said first end (10a) along said main axis (1a), said structure (10) comprising a first pipeline (100) configured to cause said fluids to be dosed and comprising:

• a plurality of second housings (12) extending from said first end (10a) to said second end (10b), each of said second housings (12) being open at least at said second end (10b) and each extending along a respective secondary axis (3a) parallel to said main axis (1a);
• first ducts (13) suitable for the introduction of said fluids to be dosed, each of said first ducts (13) being respectively in fluid passage connection with a source of one of said fluids to be dosed and with one of said second housings (12);
• shutter elements (3) each housed in one of said second housings (12) and suitable for allowing or preventing the passage through said second housings (12) of said fluids to be dosed from said first ducts (13) to an environment external to said second end (10b), said fluids to be dosed becoming dosed fluids once dispensed to an external container;
• said device (1) comprising:
• a moving element (2) suitable for moving along said main axis (1a), rotating around said main axis (1a) and moving said shutter elements (3);
• a selection element (5) constrained to said moving element (2) and suitable for engaging one of said selected shutter elements (3);
• said selected shutter element (3) being set in motion along said secondary axis (3a) by said moving element (2) by means of said selection element (5) and allowing or preventing the passage of one of said fluids to be dosed to said external environment at said second end (10b) in response to said motion, the dosed fluids being gravitationally dispensed into said external container;
• and characterized by the fact that:
• said structure (10) comprises a second pipeline (101) configured to cause washing fluids to flow, comprising detergent solutions, drying fluids, comprising gases, and undosed fluids, comprising said undosed fluids and residues of said fluids to be dosed, said second pipeline (101) comprising:
• a second duct (15) suitable for conveying said washing fluids and said drying fluids, at least to said second end (10b);
• said second duct (15) being in fluid passage connection with a tank of said washing fluids, with a tank of said drying fluids and being open at said external environment next to at least said second end (10b);
• said second duct (15) comprising a second through cavity (152) extending within said moving element (2);
• a collecting element (6) designed to prevent the dripping of undosed fluids to said external container or to a ground, to collect said undosed fluids, and to allow the dispensing of one of said selected dosed fluids.
