Upwelling cultivation facility of land-based shellfish

Abstract

The invention relates to upwelling cultivation facility of land-based shellfish. At least one aquaculture troughs are arranged inside a water tank, sieving nets are arranged on the bottoms of the aquaculture troughs, and holes are formed in the side walls of the water tank and the aquaculture troughs, one end of a drain pipe is connected with each hole, and the other end is located on the external side of the water tank, one end of a guide pipe is connected in a plugged mode with the drain pipe, the other end passing through one aquaculture trough is located inside the aquaculture trough; a water inflow pipe is located on the bottom of the water tank, a disc-type rotating water distributing device is arranged on the lower side of each aquaculture trough, the lower side of the disc-type rotating water distributing device is communicated with the water inflow pipe, the upper side is a rotary disc capable of making rotations, water outflow holes are formed in the rotary disc, the water stream passing by the water inflow pipe and into the disc-type rotating water distributing device is sprayed out through the water outflow holes, the rotary disc automatically makes rotations under the counter acting force of the water outflow stream. By the upwelling cultivation facility of land-based shellfish, water supplying is conducted on the aquaculture troughs by adopting the disc-type rotating water distributing device, no dead angle is hidden in the water stream, the rotation resistance is small, and intermittent agitation effect is achieved for shellfish capable of secreting byssus or with adhesive quality, and bio-contamination of the facility is prevented.

Description

technical field [0001] The invention belongs to the field of aquaculture engineering, in particular to a land-based upwelling cultivation equipment for shellfish. Background technique [0002] The mode of raising shellfish fry using upwelling equipment is relatively mature in foreign countries. Compared with the traditional pond hanging culture, this method has the advantages of strong water flow guidance, high breeding density, fast growth, and convenient management. The U.S. patent with the publication number US006024050A discloses a design of an upflow culture tank. The culture tank is in the shape of a chamfered truss, the aqueduct is opened downward, and a corresponding water separator is provided under the bottom screen to evenly distribute the water flow. . In this US patent US006024050A, the seedlings of shellfish tend to accumulate locally, the water flow is uneven, and the seedlings grow irregularly, requiring frequent human disturbance to redistribute them evenly...

AI Technical Summary

Problems solved by technology

However, this invention has a similar shortcoming to that of U.S. Patent US006024050A, that is, the water flow through the screen at the bottom of the culture tank is not uniform, which leads to local accumulation of shellfish fry, which increases the human workload
