Water circulation operating system for aquarium

摘要

The system has a mechanical preliminary filter (200) with a filter-basin (201), which is closed by a lid (250) to make it airtight. A degassing pipe leads from the preliminary filter to the main pump (310) through a float-controlled valve. The main outlet (104) of the aquarium tank (101) can lead through a pipe over the rim. The filter band (208,218) is guided over two deflector rollers,254), where one roller is drivable and the other is spherical. A scraper connected to a vibrator rests on the filter-band or the filter-drum and conveys dirt into a dirt-collector system, which is separate from the filter basin. An ultrasonic oscillator element consists of bar-shaped radiating elements that are arranged transversely to the filtration direction. An internal or external pump pushes or sucks the cleaning water through the filter band.
