Double-water-drainage balance device, double-water-drainage culture pond, and water flow regulation method for double-water-drainage culture pond

Abstract

The invention discloses a double-water-drainage balance device, which comprises a supporting rod arranged out of a culture pond, and a cyclone separator, wherein the cyclone separator is arranged on different heights on the supporting rod to form different water level differences with the culture pond to realize the up and down water drainage balance of the culture pond; the cyclone separator is in sliding connection with the supporting rod; the upper end of the cyclone separator is provided with a water inlet which communicates with the bottom of the culture pond, and a water outlet which communicates with a physical filter; and the bottom of the cyclone separator is provided with a pollution discharge hole. The invention provides a double-water-drainage culture pond, which comprises a culture pond body and also comprises the above double-water-drainage balance device. The upper end of the culture pond body is provided with an overflow hole which flows to the physical filter, and thewater inlet of the cyclone separator communicates with the bottom of the culture pond body. The invention provides a water flow regulation method used for the double-water-drainage culture pond. The water flow regulation method comprises the following steps of: S1: carrying out steady state regulation; S2: carrying out variable flow regulation; and S3: closing and carrying out pollution dischargeregulation.

Description

technical field [0001] The invention relates to the field of circulating aquaculture, in particular to a dual-drainage balancing device, a double-drainage aquaculture pool and a water flow regulating method thereof. Background technique [0002] The double drainage of the aquaculture pond is the most commonly used sewage design for industrial circulating aquaculture. Since the main particles produced in aquaculture are feces residues, the particles are generally concentrated at the bottom of the tank through the rotation of the water body in the aquaculture tank. If single drainage is used, that is, all water bodies are discharged through one pipeline, it will inevitably cause great pressure on the filter. . [0003] The double drainage design combines the bottom drainage of the culture pond with the surface overflow, and adopts a dual channel mode. The bottom drainage carries the main particulate matter from the bottom drainage, and it is pre-treated by a solid-liquid sepa...

AI Technical Summary

Problems solved by technology

[0004] The pipe diameters of the double drainage channels are all set through theoretical calculations, and are fixed after installation. However, in actual production, due to factors such as installation sites and individual differences in breeding tanks, there are often differences between the actual water flow and the theoretical calculations. difference, resulting in unbalanced water flow, causing overflow in culture tanks, cyclone separators or physical filtration modules

At the same time, in actual production, the breeding load often does not reach the theoretical design. Due to the limitation of water flow channels, farmers cannot reduce the water flow according to actual needs.
