Seawater stored in the aquarium of the live fish tank apparatus needs to remove sludge such as uneaten food and excrement such as live fish. Therefore, in the live fish tank apparatus of Patent Document 1, seawater is taken from a suction eye plate provided at the bottom of the water tank and is fed to the foam separation tank. And it is the structure which sludge also enters a foam separation tank with the seawater sent from the bottom part of this water tank.
Utility Model Registration No. 3107060

  In the live fish tank apparatus of Patent Document 1, solid sludge sinking to the bottom of the water tank is discharged from the eye plate for suction together with seawater, but sludge having a specific gravity smaller than seawater is discharged from the bottom of the water tank to the outside. Since it is not possible, there is a drawback that it floats on the surface of the water and accumulates in the form of bubbles. For this reason, conventionally, the worker has artificially removed the suspended matter.

  An object of the present invention is to collect sludge that exists at the bottom of a water tank and sludge that floats on the water surface in the water tank in a foam separation tank and efficiently remove it to purify the water quality.

  The present invention has been made to solve the above-mentioned problems, and its features are a water tank, a foam separation tank communicated with the water tank, and a filtration tank for filtering the water treated in the foam separation tank. In the live fish tank apparatus comprising a circulation pump tank for circulating the filtered water again to the water tank and a sterilization tank for sterilizing the circulating water, the water tank and the foam separation tank are partitioned by a partition wall, An opening for communicating the water tank and the foam separation tank and allowing the bottom water in the water tank to flow into the foam separation tank is formed in the lower part of the partition wall, and the upper part of the water tank is formed in the upper part of the partition wall. A water intake device for allowing water to flow into the foam separation tank is provided.

  The bottom water in the water tank of the live fish tank apparatus of the present invention flows into the foam separation tank through the opening. At this time, the sludge that has sunk in the bottom of the water tank also enters the foam separation tank together with the bottom water. Moreover, since the clean water in a water tank is absorbed by a foam separation tank by a water collecting device, the sludge floating on the water surface enters the foam separation tank together with the clean water.

  The foam separation tank adsorbs the sludge that flows in along with the bottom water and the sludge that flows in along with the clean water with bubbles, and discharges the floating bubbles to the outside. Sludge that has not been separated in the foam separation tank enters the filtration tank together with seawater and is filtered in the filtration tank.

  In the live water tank apparatus of the live fish tank apparatus of the present invention, a float floating on the water surface is swingably provided through an arm in an opening formed in the upper part of the partition wall. In such a device, the float moves up and down according to the water surface height in the water tank, so that sludge bubbles and clean water can be preferentially sucked into the foam separation tank. Moreover, it is a simple structure that the float is provided so as to be swingable via the arm.

  The present invention can efficiently treat the sludge at the bottom of the water tank and the sludge floating on the water surface in the water tank at one place by incorporating the bottom water and clean water in the water tank into the foam separation tank.
