This utility model relates to the field of
aquaculture, specifically disclosing an
aquaculture circulating water purification device, including a circulating water tank mechanism, a waste
discharge mechanism, and a water inlet mechanism. The circulating water tank mechanism includes a water tank, with a water pump fixed to the lower end of the outer side of the water tank, and a connecting
water pipe fixed to the upper end of the water pump. The waste
discharge mechanism includes a bend, with a waste
discharge pipe fixed to the lower end of the bend, a valve installed on the waste discharge
pipe, and several filter holes on the upper outer side of the bend. A fixing
flange is also installed on the outer side of the bend. This utility model guides
wastewater from the
aquaculture tank into the bend through the water inlet mechanism. The several filter holes on the upper outer side of the bend perform fine
filtration of the
wastewater, and the valve installed on the waste discharge
pipe allows the
wastewater to be quickly discharged from the device by simply opening the valve when there is a large amount of impurities accumulated in the water tank due to
filtration.
