Problems solved by technology

The disadvantage of this technology is that the larger pipes create a lot of drag within the water column and impair the rotational speed, which also impairs the self-cleaning properties of this system
[0008] The apparatus disclosed herein overcomes the above major deficiencies in aquaculture recirculation systems, namely solids breakdown, high cost of sewage and water treatment, poor water circulation in tanks, and inefficient removal of bulky solids

Embodiment Construction

[0026] In the aquaculture recirculation water system, the aquaculture tank (10) is used to hold water, and aquatic organisms, usually fish, are to be cultivated in the water. For optimum water circulation, the tank (10) has a generally circular cross-section, such as figure 1 As shown, the figure shows a top view of an aquaculture system comprising a preferred embodiment of the triple drainage arrangement in question. For optimal use of floor space, the sink (10) can also have other cross-sectional shapes, such as hexagonal, or even roughly square, as long as the corners are rounded and not sharp enough to disturb the water circulation. For the purposes of this disclosure, circular structures are depicted and described.

[0027] The sink (10) has generally cylindrical sink side walls (12) and a sink bottom wall (14). Preferably, the tank bottom wall (14) is slightly conical, forming an apex (11) near the center of the tank, as shown in Figures 2(a) and 2(b). The sink (10) c...

Abstract

Triple drain apparatus for an aquaculture system tank for reducing water input requirements and minimizing breakdown of solids whereby the solids are larger and more concentrated when removed from a solids settling device. Water flow is split by the apparatus into a side box fluid stream which flows into a side box coupled to the tank, and both a clean fluid stream and a high solids fluid stream which flow into a center drain. The center drain comprises a central stand pipe coupled to a clean water outlet, a sump coupled to a high solids fluid outlet and a collection plate separating the tank and the sump. The center drain may include a mortality trap coupled to a mortality outlet and the sump, whereby the collection plate separates the mortality trap from the sump, to provide means for easily removing dead fishes and large debris from the tank.

Description

technical field [0001] The present invention relates to equipment for recirculating water systems in aquaculture, in particular triple drainage equipment, designed to remove solid waste such as excrement, residual bait and dead fish from common aquaculture operations in aquaculture tanks. Background technique [0002] In aquaculture recirculating water systems, 95% of the solids are produced in the culture tanks. Solids in the tank can include, for example, fish waste, bait and dead fish. These solids remain in the tank and can cause poor water quality and damage the health of the fish. The key to good water quality in centralized recirculating water systems is collecting these solids and removing them from the tank before they decompose. [0003] Proper sink hydraulics are important to produce a self-cleaning sink, proper sink hydraulics require creating what is known as the "teacup effect" which creates a strong flow of water along the bottom of the sink to bring solid w...
