semisulcospira only farming water tank and multifunctional double drainpipe

摘要

The present design relates to a circular water tank aquaculture system including aquaculture wave plate 145 for aquaculture in the inland water surface, and more specifically, without removing or moving the culture wave plate 145 in the sea water tank, The excrement can be discharged, and even when shipped, the cultured wave plate 145 is not shaken or removed, and is discharged together with the cultured water through the drain to enable collective collection. In general, in the aquaculture of fish using a circular tank, if the breeding water stored inside the tank body is formed in a swirling flow, solid components such as fish excrement and feed debris are found in the tank body equipped with a water level control device. Efficient and various advantages are provided, such as being able to collect and discharge toward the center. However, under the condition that the culture wave plate 145 is installed on the bottom of the tank, the discharge port 116 is installed at the bottom of the tank wall so that the rotation centered on the bottom of the tank can be made. A net 124 capable of forming the aquaculture wave plate 145 is installed at a position higher than the discharge port 116 so that the aquaculture wave plate 145 and the tank bottom 122 are spaced apart so that a swirling flow can be generated at the bottom of the tank. In addition, in order to help the flow of swirling flow and increase the effect of collecting debris, the bottom of the water tank is shaped like a funnel fan, and a multifunctional double drainage pipe 163 is installed in the center of the outer pipe 162 at the lower end of the outer pipe 162 for eddy flow. By forming more than one suction port 167 and forming the pipe length higher than the inner pipe 164 above the water tank, it is not drained to the upper part of the outer pipe 162 but only the upper part of the inner pipe 164 When the generated swirling flow transfers contaminants from the bottom of the tank to the center of the tank, it is sucked through the suction port 167 formed under the outer pipe 162 and discharged to the upper portion of the inner pipe 164. In addition, the inner pipe 164 of the multi-functional double drainage pipe 163 is formed in a separate type so that it is separated from the water tank when shipped to Daseulgi, and collected at once through the drainage port along with drainage.
