Abstract
The circulating water system for intensive aquaculture disclosed herein includes a submersible pump, an outlet tube, an outer casing tube and a deflector plate. The submersible pump is adapted for being mounted on the bottom of an aquaculture pool at a position close to the circumferential wall. The outlet tube has a tapered section sleeved onto a discharge port, while the outer casing tube is sheathed outside the outlet tube. The deflector plate is mounted laterally to the submersible pump, such that when the submersible pump is pumping water from the aquaculture pool through the discharge port, the deflector plate acts to guide the discharged water approach the circumferential wall, thereby generating a circulating swirling flow rotating in tangential direction along the circumferential wall.
Claims16
A circulating water system for intensive aquaculture, comprising:
- a submersible pump adapted for being mounted on a bottom wall of an aquaculture pool at a position close to a circumferential wall of the aquaculture pool, the submersible pump being provided at one end with a base, which is formed with a suction port and a discharge port and provided with a propeller adapted to be driven by the submersible pump to rotate at a high speed to generate a suction force, such that water is sucked into the submersible pump through the suction port and then discharged from the submersible pump through the discharge port, wherein the discharge port has a discharge direction arranged in parallel to a tangential direction of the circumferential wall;
- an outlet tube configured in form of a hollow tube having a tapered section sleeved onto the discharge port;
- an outer casing tube configured in a hollow tubular shape and sheathed outside the outlet tube, the outer casing tube having an inner diameter and a length greater than an outer diameter and a length of the outlet tube;
- and
- a deflector plate mounted laterally to the submersible pump and having a length covering the submersible pump and the outer casing tube, such that water discharged from the discharge port is guided by the deflector plate to approach the circumferential wall to generate a circulating swirling water flow.
A circulating water system for intensive aquaculture, comprising:
- a land-based aquaculture pool comprising a bottom wall and a circumferential wall erecting at a circumference of the bottom wall;
- a submersible pump adapted for being mounted in the land-based aquaculture pool at a position close to the bottom wall and the circumferential wall, the submersible pump being provided at one end with a base, which is formed with a suction port and a discharge port and provided with a propeller adapted to be driven by the submersible pump to rotate at a high speed to generate a suction force, such that water is sucked into the submersible pump through the suction port and then discharged from the submersible pump through the discharge port, wherein the discharge port has a discharge direction arranged in parallel to a tangential direction of the circumferential wall;
- an outlet tube configured in form of a hollow tube having a tapered section sleeved onto the discharge port;
- an outer casing tube configured in a hollow tubular shape and sheathed outside the outlet tube, the outer casing tube having an inner diameter and a length greater than an outer diameter and a length of the outlet tube;
- and
- a deflector plate mounted laterally to the submersible pump and having a length covering the submersible pump and the outer casing tube, such that water discharged from the discharge port is guided by the deflector plate to approach the circumferential wall to generate a circulating swirling water flow.
