Nozzle arrangement for injecting liquid into a tank

A nozzle arrangement for injecting a liquid into a tank, said nozzle arrangement comprising:

• a down pipe (3) having a lower end;
• a pipe section (4)
• rotatably arranged at a lower end of the down pipe (3) with a rotational axis coinciding with a longitudinal axis of the down pipe (3), and
• said pipe section (4) comprising an angled cleaner head (5) distal to position at which the pipe section (4) is rotatably arranged at the down pipe (3);
• an angled nozzle pipe section (7);
• a nozzle hub (15) provided for rotatably connecting the angled nozzle pipe section (7) to the pipe section (4) at the cleaner head (5);
• wherein the nozzle arrangement further comprises a rotating mechanism (8) comprising
• a primary drive shaft (13) being connected to said pipe section (4);
• a row of gear teeth (9) fixedly arranged on or formed in the lower end of the down pipe (3) on an outside thereof;
• an angular gear (10);
• a worm gear (16) arranged to rotate the nozzle pipe section (7) at the cleaner head (5) driven by the angular gear;
• and
• a secondary drive shaft (11) rotatably mounted on an outside of said pipe section (4) and having at one end a gear wheel of the angular gear (10) and at the other end a gear wheel (12) co-operating with said row of gear teeth (9).
