## Abstract

To achieve complete cleaning of a tank (11) by means of a cleaning head (4, 5) having nozzles (6) mounted on a liquid supply pipe (3), the cleaning head (4) according to the invention is provided with one or more nozzle openings, nozzles (7), which eject a jet/jets (8, 9) against the supply pipe/suspension (3). This ensures that the stationary parts of the cleaning equipment (3, 10) are cleaned effectively during the turning (4a) of the cleaning head (4) and thereby of the nozzle/nozzles (7).

## Claims

### Claim 1

A cleaning assembly comprising:
a cleaning housing (4) mounted on a liquid supply pipe (3) and having means for turning the housing (4) at the same time as a hub (5) having nozzles (6) is rotated
wherein one or more nozzle or nozzle openings (7) are provided on the tunable part of the housing (4),
and wherein the nozzle or nozzle openings (7) provided on the turnable part of the housing (4) comprise means suitable for ejecting a liquid jet against the supply pipe for the cleaning of the supply pipe during the turning movement of the housing (4), the nozzle or nozzle openings (7) provided on a side of the housing (4) which faces toward the rotating hub (5).

### Claim 2 (depends on 1)

A cleaning assembly according to claim 1, characterized in that the nozzle or nozzle openings (7) are configured such that the jets (8, 9) are directed toward various points on a hub cone (10) or the supply pipe (3), or toward various points on both the hub cone (10) and the supply pipe (3).
