ABSTRACT:
A cleaning apparatus with cleaning rings for cleaning cylindrical bodies, preferably for the quartz cladding tubes in UV disinfection units, especially in UV disinfection sluices for waste water, which in addition to an axially parallel longitudinal movement over the outside surfaces perform an additional angularly limited and alternating rotational movement The object of the invention is a cleaning apparatus with cleaning rings for cleaning cylindrical bodies, preferably for the quartz cladding tubes in UV disinfection units, especially in UV disinfection sluices for waste water, which in addition to an axially parallel longitudinal movement over the outside surfaces perform an additional angularly limited and alternating rotational movement. According to the inventive idea the cleaning rings are moved slowly in an axially parallel way over the quartz cladding tubes, with the same moving additionally in an angularly limited and with suitable speed alternatingly about a rotational axis for reinforcing the cleaning performance and especially for the better penetration of troughs at places that are out of round. This manner of movement of the cleaning rings necessitates a considerably lower amount of mechanical complexity at virtually the same cleaning performance than would be necessary in a full and uninterrupted rotation of the cleaning rings. Compared with the usual rigid wiper rings which are moved back and forth in an axially parallel manner on the quartz cladding tubes without any rotational movement, the cleaning performance with the cleaning rings according to the inventive idea is considerably better.
