Embodiment
In the following description, a large amount of concrete details are given more thoroughly to manage in order to provide to the utility model
Solution.It is, however, obvious to a person skilled in the art that the utility model may not need it is one or more of these thin
Save and be carried out.In other examples, in order to avoid obscuring with the utility model, for more well known in the art
Technical characteristic is not described.
In order to thoroughly understand the utility model, detailed step and detailed structure will be proposed in following description,
To explain the technical solution of the utility model.The preferred embodiment of the utility model is described in detail as follows, but except these
Outside being described in detail, the utility model can also have other embodiment.
The utility model provides a seed oyster different developmental phases young separation and concentration device, with reference to shown in Fig. 1-3, bag
Stent 1 and funnel 2 are included, as shown in Figure 1, being provided with 3 funnels 2,3,4 on stent, is provided with strainer in each funnel, from top to bottom
Strainer mesh number in funnel 2 incrementally increases, i.e. the strainer 2a of funnel 2, the strainer 3a of funnel 3, funnel 4 strainer 4a mesh numbers progressively
Increase.In addition, bottle neck is provided with valve below each funnel, and valve bottom is provided with receiving flask, valve is flowed through for control
The current of strainer enter in receiving flask.Fig. 2 shows the front view of funnel 2, and strainer 2a is equipped with funnel 2, and bottom is equipped with valve
Door 2b and receiving flask 2c.
The utility model filtration apparatus is used for zooplankter Drifting egg and viscid egg, and D-shaped larva, juvenile mollusk are planted
