Embodiment 1
[0021] Such as figure 1 As shown, the device includes a negative pressure generator 1 and an algae collection box 3 , and the negative pressure generator 1 and the algae collection box 3 are connected through a coupling cover 2 . The top of algae collection box 3 is provided with inlet, and the bottom is provided with outlet, and its inlet is connected with suction pipeline 10, and its outlet is connected with drainage pump 6 by pipeline. In the algae collection box 3, a plug 9 is provided at its entrance, and an algae collection bag 5 is tied on the plug 9 by a non-metal strip, and the algae and water mixture in the suction pipe 10 directly flows into the algae collection bag 5 through the plug 9 . The algae collection bag 5 is provided with circular holes at intervals, and the aperture is 1mm, and the water in the algae collection bag 5 flows out along the circular holes; figure 2 As shown, the edge of the hole is provided with flexible barbs 11 toward the algae collectio...
Embodiment 2
[0025] The cross-sectional shape of the suction pipe is elliptical, and the shape of the pipe suction opening is also elliptical at this time, that is, its size and shape are consistent with the cross-section of the pipe.
[0026] Others are with embodiment 1.
Embodiment 3
[0028] The cross-sectional shape of the suction pipe is as Figure 5 As shown, it is composed of two half ellipses, wherein the major axes of the two half ellipses are equal, and the length of the minor axis is different. The bottom of the pipe is located at the end of the major axis. The shape of the pipe outlet can be circular, and its diameter is not smaller than the major axis of the ellipse; the shape of the outlet can also be consistent with the cross-sectional shape of the pipe.
[0029] Others are with embodiment 1.
