High density spiral-flow circulation fresh water fish raising pool device

This utility model provides a high density rotational flow circulating clean water fishpond device which adopts the physical and biological purification, circulating oxygenation, air-water backwashing and rotational flow feces (impurity) collection; the device is characterized in that the rotational flow fish pond is a round or elliptical cone-shaped fish pond, the upper edge of rotational flow fish pond is provided with a clean water mouth which supplies water to the pond along the circle tangential direction of this pond, a clean water tube is connected with the clean water mouth, the other end of the clean water tube is connected with the water outlet of oxygenation self-purging terminal home use water purifier, the tapered bottom of rotational flow fish pond is provided with a suction hole and a suction pipe; the suction pipe is connected with the water pump outwards along the inner edge of the rotational flow fish pond, and a water-pressing pipe of the water pump is connected with the oxygenation self-purging terminal home use water purifier. The fish manure (impurity) is gathered in the center of pond maximally with the waterpower rotational flow mode to be removed, so as to make the pond water clean; after the water containing fish manure (impurity) crosses the oxygenation terminal self-purging home use water purifier, the oxygenation clean water will return to the pond for repeated use.
