A dual-channel inflow system with variable flow rate circulation and effective sewage discharge at the bottom of the pool

Abstract

The present invention provides a dual-channel inflow system with variable flow rate circulation and effective sewage discharge at the bottom of the pool, comprising: the water inlet system I includes a vertical water inlet pipe I and a horizontal ring-shaped water inlet pipe, the lower part of the vertical water inlet pipe I and the ring-shaped water inlet pipe The water inlet pipes are provided with a number of water inlet holes; the water inlet system II includes a vertical water inlet pipe II, and the vertical water inlet pipe II is provided with a number of water inlet holes at equal intervals from top to bottom; the solenoid valve control system I and solenoid valve control System II is respectively set at the connection between the vertical water inlet pipe I and the vertical water inlet pipe II and the main pipe; the drain pipe is set at the bottom of the culture pond and communicates with the culture pond; the circulating water pump One end communicates with the drain pipe, and the other end communicates with the main pipe. The technical scheme of the invention solves the problems that the traditional water inlet system structure is not easy to realize variable flow rate circulation and is insufficient to provide hydrodynamic conditions required for sewage collection and discharge.

Description

technical field [0001] The invention relates to the field of aquaculture engineering, in particular to a dual-channel inflow system with variable flow rate circulation and effective sewage discharge at the bottom of the pool. Background technique [0002] Recirculating aquaculture system (RAS for short) is a green and healthy aquaculture model that integrates modernization, controllability and intensification. The production process is controllable, and cross-seasonal perennial breeding is realized. At the same time, less waste water is discharged. And it is easy to concentrate on processing. It has a stable and high yield while causing less pressure on the environment. It has good social, economic and ecological benefits, and has gradually developed into one of the mainstream models of aquaculture. [0003] The recirculating aquaculture industry has ushered in vigorous development, but it is also facing many production problems. At present, the production problems faced by...
