All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, an embodiment of the present invention provides a tail water filtering apparatus, which includes a first recovery pipe 1, a second recovery pipe 2, an inner screen 3 having a first inlet 31, and an outer screen 4 having a second inlet 41; wherein,
a plurality of first meshes (not shown in the figure) are distributed on the surface of the inner-layer filter screen 3, a plurality of second meshes (not shown in the figure) are distributed on the surface of the outer-layer filter screen 4, and the aperture of each first mesh is larger than that of each second mesh; the inner filter screen 3 is arranged in the inner cavity of the outer filter screen 4 and is connected with the outer filter screen 4, the first inlet 31 and the second inlet 41 have the same direction, a gap is reserved between the bottom of the inner filter screen 3 and the bottom of the outer filter screen 4, and a first valve 5 is arranged on a passage of the first recovery pipe 1; one end of the first recovery pipe 1 is communicated with the bottom of the inner-layer filter screen 3; one end of the second recovery pipe 2 is communicated with the bottom of the outer layer filter screen 4, and a second valve 6 is arranged on the passage of the second recovery pipe 2.
In this embodiment, mode such as inlayer filter screen 3 and outer filter screen 4 accessible bolted connection, gluing, weave is connected, and the mode of accessible grafting is connected between first recovery pipe 1 and the inlayer filter screen 3, specifically, can set up first grafting through-hole on inlayer filter screen 3 and insert first grafting through-hole with the one end of first recovery pipe 1 from the outside to realized the connection of the two and easily dismantled at any time. Similarly, the second recycling pipe 2 and the outer filter screen 4 can be connected by plugging, specifically, the outer filter screen 4 can be provided with a second plugging through hole and one end of the second recycling pipe 2 can be inserted into the second plugging through hole from the outside, so that the connection between the two is realized and the disassembly is easy to be performed at any time. In practical application, the joint of the recovery pipe and the filter screen can be fixed by weaving and the like. In addition, the outer layer filter screen 4 should be provided with a clearance through hole corresponding to the first recycling pipe 1, so that the first recycling pipe 1 can penetrate through the outer layer filter screen 4 and is communicated with the inner layer filter screen 3. The first valve 5 and the second valve 6 are preferably gate valves, and valve body portions of the gate valves are respectively disposed on the passages of the first recovery pipe 1 and the second recovery pipe 2, and the valve bodies are controlled to be opened or closed by a driving device, so as to control the passage of the first recovery pipe 1 and the passage of the second recovery pipe 2 to be turned on or off.
The tail water filtering device of the embodiment is applied to the specific installation process and the working flow of the ship type fishery culture system as follows:
firstly, the inner-layer filter screen 3 and the outer-layer filter screen 4 are respectively installed at the bottom of the culture cabin 7 in the collection cabin 8, and the first inlet 31 and the second inlet 41 are opposite to the discharge port 71 at the bottom of the culture cabin 7, wherein a cover plate or a valve can be arranged at the discharge port 71, and the cover plate or the valve is kept closed in the installation process to prevent the culture water body in the culture cabin 7 from flowing out of the discharge port 71.
