Description

Pond is bred on dirty blowdown runway of collection

Technical Field

The utility model relates to a culture pond, in particular to a sewage collecting and discharging runway culture pond, and belongs to the technical field of aquaculture.

Background

The runway type culture pond is a culture mode integrating the characteristics of high-level pond culture and industrialized intensive culture, a water-stop wall is generally added in the middle of the culture pond, and a gap is reserved between the water-stop wall and the pond wall, so that water in the culture pond can rotate around the water-stop wall when water is fed or oxygenated, still water becomes flowing water, and the running water is named as a runway type culture pond because the running water is like a track and field runway. The typical runway uses circulating water operation, and the technology with high requirements on high-density cultivation and circulating water operation needs to invest more capital to build infrastructure, increase biological safety, build additional control tools and the like. The runway culture has high requirement on water quality due to high density, needs a filter system, microorganisms, siphoning, temperature control, high-quality feed and the like, and aims to provide a stable environment for cultured objects and realize high-efficiency culture.

At present, the runway type culture pond is mainly used for culturing penaeus vannamei boone, and has the problems of poor sewage collection effect, small sewage discharge amount, heavy water pollution and the like, so that the utilization rate of most of the runway type culture ponds in China is low, the culture effect is not good, and the development of the runway type culture pond is restricted.

SUMMERY OF THE UTILITY MODEL

The utility model provides a sewage collection and drainage runway culture pond which can quickly remove organic particulate matters in a runway fish pond, reduce water pollution and improve culture effect. The utility model discloses a adopt following technical scheme to realize:

a sewage collecting and discharging runway culture pond comprises a waterwheel used for controlling water flow velocity, a rotational flow device used for collecting sewage and a discharge pipeline; the waterwheels are arranged on two sides of the runway guide wall; the rotational flow device is arranged at the arc-shaped parts at two ends of the raceway pond and has an upper ring structure and a lower ring structure, the side surface of the upper ring is provided with a water inlet, the side surface of the lower ring is provided with a water outlet, and a rotational arc-shaped guide plate blade with consistent guide is arranged between the upper ring and the lower ring; a sewage draining outlet is formed in the bottom of the rotational flow device; the sewage discharge pipeline is connected with the sewage discharge port.

Preferably, the sewage draining outlet is provided with a conical sewage collecting hole, and the sewage draining pipeline is connected with the conical sewage collecting hole.

Preferably, the upper loop height is 2/3 the lower loop height.

Preferably, the waterwheel is a jet aerator, a waterwheel aerator or a water turbine.

Preferably, the cyclone device is made of PE plates or stainless steel.

Preferably, the sewage discharge pipeline is provided with a solenoid valve for controlling the timed and quantitative discharge of the sediments to the external environment.

The utility model has the beneficial effects that:

1) can rapidly remove organic particles in the runway fishpond and reduce water pollution.

2) The water wheel of the culture pond is used for providing power, and extra power is not needed.

3) The cyclone is divided into an upper circle and a lower circle, the cyclone effect is enhanced by the gravity of the water body, and the design is ingenious.
