In the present invention, described ejector comprises suction chamber, mixing tube and anemostat, and described suction chamber, mixing tube and anemostat are located along the same line and are communicated with successively.
In the present invention, also be provided with horn-like opening, a plurality of high pressure nozzles circumferentially evenly be set at the described horn-like opening in described horn-like opening upper edge at described ejector fish inlet and described suction chamber connection.
The present invention can be improved to: the angle between described horn-like opening and the described suction chamber is 90 °, and described a plurality of high pressure nozzle is 1.5 times of the mixing tube internal diameter apart from the horizontal range of mixing tube front end.
The present invention also can do following improvement: the ratio of the sum of the cross-sectional area of described mixing tube and described a plurality of high pressure nozzle cross-sectional areas is 3.57.
The present invention also can do following improvement: the axial length of described mixing tube is 5-7 times of its internal diameter.
In the present invention, described anemostat is a truncated cone-shaped, and the less end of its internal diameter is connected with described mixing tube, and the end that its internal diameter is bigger is connected with described row fish pipe.
The present invention can also do following improvement: the angle between the inwall of described anemostat and its horizontal middle spindle is 4 °.
In the present invention, be respectively equipped with the horn opening that Open Side Down at the fish inlet place of described pumping fish tube and the water inlet of described suction hose.
Compared with prior art, the invention has the beneficial effects as follows:
1.. the present invention utilizes the energy of high speed operation fluid to finish the conveying of fish, realized that uninterrupted the rising continuously of free of losses of deep water mesh cage cultured fishes catch, shortened the catches in deep sea net cages working time greatly, reduced the fish body mechanical loss that causes because of the etting friction in the fishery harvesting process, cultured fishery harvesting for the large-scale industrialization deep water mesh cage equipment basis is provided;
2.. simple in structure, assembling is easy, and reliable operation does not need complicated electric control system, has very high safe handling;
3.. the multi-jet design of the present invention, can better make suction chamber form vacuum, make things convenient for fish to rise and catch.
4.. the material that the impeller of ejector of the present invention and work water pump uses can be stainless steel, stainless steel material has very strong corrosion resistance characteristic, make apparatus of the present invention can in the seawater cage culture process, carry out fish for a long time and rise and catch, can use in that briny environment is medium-term and long-term.
