Rotating head for cleaning cisterns, tanks, containers and the like, in particular for cleaning and disinfecting the inner walls of cisterns, tanks or other containers, with or comprising a rotating body that can be positioned inside the
cistern, tank or other container and that is driven by a
drive shaft driven by an external motor and is equipped with nozzles for spraying cleaning fluid onto the inner walls of the
cistern, tank or other containers, characterized in that the head comprises: - a product feed part (1) having a generally
cylindrical tube shape, which can be fastened by means of screws through through-holes (4) provided in an extension of a skirt or
flange (3), wherein the product feed part (1) has internal receptacles (5) dimensioned and designed to receive seals (6), which are designed in particular for operation at high pressures of up to 200 bar and high temperatures of up to 110 °C, wherein the product feed part (1) has a feed opening (2) in the form of a threaded bore for the supply of cleaning and disinfecting agents, which allows the attachment of a standard fitting, and - a closure disc comprising a detachable structure made up of two circular discs of different diameters: a larger closure disc (9) with a larger
diameter and a smaller closure disc (8) with a smaller
diameter, which is obtained by separating the closure disc (9) with a larger
diameter and is surrounded by a metallic element or disc (10) formed as an annulus and which overlaps the outer
edge region of the closure disc (8) with a smaller diameter and is connected to the disc with a larger diameter by spot welds (11) or a
weld seam, wherein the fixed connection with the larger closure disc (9) is provided by means of screws and threaded holes (12), and wherein a vent or
check valve (13) is fitted on the closure disc (8),which allows air to enter from the outside when there is negative pressure inside, and , - at least one
nozzle comprising a substantially cylindrical main body (101) provided with a longitudinal opening (102) for the flow of liquid, wherein three regions are defined in this body: a lower thread (103), a middle region (104) with at least one
facet or flattening (105) and an upper thread (106) on which an inverted shell (107) with a corresponding complementary internal thread is mounted, wherein the shell has a central opening (108) at its upper base, the diameter of which is larger than that of the longitudinal opening (102), and wherein the shell (107) has a pair of opposing transverse windows (109) through which a flow selector plate (110) can be displaced, in which at least two openings (111, 112) of different diameters are provided, wherein a safety button (115) is axially displaceable in the middle region (104) of the main body (101),which is pressed upwards by a steel band or a spring (116) which rests on the top of a nut (117) which is screwed onto the lower thread (103) of the main body, wherein a support and pressure surface for the user's fingers is defined on this safety button (115) and the safety button (115) is provided on its top with one or more teeth (118) which engage in one or more recesses (119) on the lower edge of the inverted shell (107).
