Description

Technical Field

[0001] This utility model relates to the field of shrimp farming technology, specifically to a shrimp farming pond. Background Technology

[0002] Shrimp farming ponds often lack a porous, soil-like buffering medium, leading to prolonged retention of waste at the bottom. This prolonged contact between waste and shrimp can induce various diseases, resulting in poor or even failed shrimp farming. Existing shrimp farming ponds often use only one type of aeration device, failing to provide comprehensive oxygenation throughout the pond. Utility Model Content

[0003] The purpose of this utility model is to address the above-mentioned shortcomings by providing a shrimp farming pond.

[0004] This utility model includes an aquaculture pond, an oxygenation pump installed next to the aquaculture pond, and a water supply pipe;

[0005] The aquaculture pond has a cylindrical structure. The bottom center of the pond is concave to form a recess for accommodating a submersible pump. The submersible pump is surrounded by an isolation net cover, which includes a mesh cylindrical part and a top mesh plate. The top mesh plate has a notch for the water pump pipe to extend out.

[0006] The end of the pumping pipe is connected to the inlet of a solid-liquid separator located next to the aquaculture pond, and the outlet of the solid-liquid separator is connected to a return pipe located above the aquaculture pond. The end of the return pipe is equipped with a filter bag.

[0007] The outlet end of the oxygenation pump is connected to the oxygenation pipe, which is connected to the air outlet assembly located at the bottom of the aquaculture pond. The air outlet assembly includes an annular pipe a, an annular pipe b, and a set of connecting pipes that connect the two. The bottom of the annular pipe a and the annular pipe b are evenly provided with multiple air outlet holes.

[0008] Preferably, the isolation mesh cover is made of stainless steel.

[0009] Preferably, the solid-liquid separator is a centrifugal solid-liquid separator.

[0010] Preferably, the filter bag is a 100-200 mesh nylon mesh bag, and the opening of the filter bag is tied to the end of the return water pipe with a fixing rope.

[0011] Preferably, the diameter of the annular tube a is twice the diameter of the annular tube b.

[0012] Preferably, the bottom of both the annular tube a and the annular tube b is provided with multiple support rods that are fixedly connected to the bottom of the aquaculture pond.

[0013] Preferably, the annular tube a is further provided with a connecting pipe that communicates with the oxygenation tube.

[0014] Preferably, the rear section of the pumping pipe is also connected to a drain pipe with valve a, and valve b is provided at the connection between the end of the pumping pipe and the inlet of the solid-liquid separator.

[0015] The advantages of this invention are: Waste at the bottom of the pond is periodically discharged via a submersible pump and solid-liquid separator, reducing the contact time between waste and shrimp, thus preventing disease and ensuring optimal shrimp farming results. Aeration is achieved by installing air vents at the bottom of the pond, ensuring comprehensive oxygenation and preventing problems such as pond turnover and low shrimp vitality caused by insufficient oxygen supply.
