Orientable device for washing and also sanitizing a conveyor belt

Washing and also sanitizing device (10a, 10b), of the spray and orientable type, for a conveyor belt (200) of an automatic handling installation (20) with supporting structure (201) with side rails (204), which device (10) has two tubular spray bars provided with atomising nozzles, integral and parallel to each other, which can be positioned horizontally above and below it without touching it so that the sprays of the nozzles simultaneously hit one of its portions of both external and internal surface, in all its width (200, L);

• said washing device (10a, 10b), with a single inlet (130) of the washing fluids to connect to an external flow network (205) with continuous flow;
• said washing device (10a, 10b), being joinable to said supporting structure of the installation (20, 201) in an integral way, with fixing means of the mechanical type;
• said washing device (10a, 10b), consisting of a single tubular and coplanar structure, open on one side like a fork, with a first upper spray bar (101) and a second lower spray bar (102) which are parallel to each other and are joined on one side to a common riser of supply (103) of the washing fluids arranged orthogonally to them, while on the opposite side they are individually closed and terminate without junctions;
• and where said supply riser (103) has a monodirectional flow from the bottom upwards, with the inlet (130) in correspondence with the lower end and with the opposite end bent like an elbow (132) which is butt-joined horizontally to said first spray bar (101), while said second spray bar (102) is connected orthogonally to said riser (103) with a connection;
• and where the washing flow enters from the bottom perpendicularly (103, 130, 131) to said spray bars (101, 102) and continues therein exiting the atomizing nozzles (104) which are aligned;
• and where said fork-like (101, 102) washing device (10a, 10b) can be joined into said supporting structure (201) by inserting it sideways and fixing only one spray bar through at least one fixing means to support it and lock it to the conveyor belt (200) in correspondence with a side rail, and thus fixing the entire device (10a, 10b) in an integral and removable way, in operative position;
• and where the other spray bar is self-supporting, being joined on one side to said supply riser (103) with said connection;
• said washing device (10a, 10b), characterized in that the first upper spray bar (101) is provided with at least one preassembled fixing group (106), of the bracket type with clamp, and wherein the washing device (10a, 10b) can be oriented in its positioning with respect to the belt (200), oscillating (102, 103, 133) around the longitudinal axis of the first spray bar (101, 125) until said fixing group (106) is completely tightened in such a way as to lock the supply riser (103, 134) and the second spray bar (102) in the desired position.
