Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to an aquaculture pond. Background Technology

[0002] Aquaculture is the cultivation of fish, crustaceans, mollusks, aquatic plants, algae, and other organisms. Aquaculture ponds are pools used for aquaculture, typically including earthen ponds, concrete ponds, and PP ponds. With long-term use, the excrement in aquaculture ponds can lead to the proliferation of bacteria in the water, endangering the safety of aquatic animals and potentially causing their death. Currently, most aquaculture ponds simply maintain water quality by changing the water, discharging wastewater and adding clean water. However, directly discharging wastewater not only pollutes the environment but also wastes water resources. Utility Model Content

[0003] The purpose of this invention is to provide an aquaculture pond that addresses the shortcomings of existing technologies, enabling the purification and reuse of aquaculture wastewater discharged from the pond, thereby reducing water waste.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an aquaculture pond, including a pond body, and further including an oxygenation mechanism for introducing oxygen into the pond, and a water purification and circulation mechanism for treating wastewater and adding the treated clean water into the pond. The water purification and circulation mechanism includes a wastewater purification device, an inlet pipe, and an outlet pipe. The wastewater purification device is located on one side of the pond and includes a wastewater sedimentation tank, a dosing port on the wastewater sedimentation tank, a wastewater filter tank below the wastewater sedimentation tank, and a filter screen inside the wastewater filter tank. The wastewater sedimentation tank and the wastewater filter tank are connected by a pipe. One end of the inlet pipe is connected to the pond, and the other end of the inlet pipe is connected to the inlet of the inlet pump. The outlet of the inlet pump is connected to the wastewater sedimentation tank. One end of the outlet pipe is connected to the wastewater filter tank, and the other end of the outlet pipe is connected to the inlet of the outlet pump. The outlet of the outlet pump is connected to the pond.

[0005] A further improvement to the above solution is that the sewage sedimentation tank is also provided with a stirring assembly, which includes a stirring shaft rotatably disposed inside the sewage sedimentation tank, stirring blades disposed on the stirring shaft, and a stirring drive motor disposed on the sewage sedimentation tank. The power output end of the stirring drive motor is connected to the stirring shaft.

[0006] A further improvement to the above solution is that the filter screen has two layers, and both layers of the filter screen are detachably installed inside the sewage filter tank.

[0007] A further improvement to the above scheme is that the bottom of the sewage sedimentation tank is provided with an isolation component, and several isolation components are provided, which are evenly arranged on both sides of the inlet of the pipeline.

[0008] A further improvement to the above scheme is that the cross-section of the isolation element is trapezoidal and narrower at the top and wider at the bottom, and a deposition groove is formed between two adjacent isolation elements.

[0009] A further improvement to the above solution is that the oxygenation mechanism includes an oxygenation pump and an air pipe. The oxygenation pump is located on one side of the aquaculture pond, one end of the air pipe is connected to the outlet of the oxygenation pump, and the other end of the air pipe extends into the aquaculture pond.

[0010] A further improvement to the above solution is that escape-proof nets are installed at the connection points between the water inlet pipe, the water outlet pipe, and the aquaculture pond.

[0011] A further improvement to the above scheme is that a sewage pipe is provided in the middle of the bottom of the breeding pond, and a solenoid valve is installed inside the sewage pipe.

[0012] A further improvement to the above scheme is that the aquaculture pond body is provided with multiple units.

[0013] The beneficial effects of this utility model are as follows: This utility model includes an oxygenation mechanism for filling the aquaculture pond with oxygen, and a water purification and circulation mechanism for treating sewage and adding the treated clean water to the aquaculture pond. The water purification and circulation mechanism includes a sewage purification device, an inlet pipe, and an outlet pipe. The sewage purification device is located on one side of the aquaculture pond. The sewage purification device includes a sewage sedimentation tank, a dosing port on the sewage sedimentation tank, a sewage filter tank below the sewage sedimentation tank, and a filter screen inside the sewage filter tank. The sewage sedimentation tank and the sewage filter tank are connected by a pipe. One end of the inlet pipe is connected to the aquaculture pond, and the other end of the inlet pipe is connected to the inlet of the inlet pump. The outlet of the inlet pump is connected to the sewage sedimentation tank. One end of the outlet pipe is connected to the sewage filter tank, and the other end of the outlet pipe is connected to the inlet of the outlet pump. The outlet of the outlet pump is connected to the aquaculture pond.

[0014] This invention features an oxygenation mechanism to ensure suitable oxygen content in the aquaculture pond, and a water purification and circulation mechanism. Aquaculture wastewater is pumped into the wastewater purification device via an inlet pump. Sedimentation and disinfection agents are added to the wastewater sedimentation tank through the dosing port, where impurities are deposited and disinfected. The wastewater is then filtered through a filter screen in a wastewater filtration tank. This process of disinfection, sedimentation, and filtration purifies the wastewater discharged from the aquaculture pond. The purified water is then pumped back into the aquaculture pond via an outlet pump, achieving water purification and circulation and reducing water waste. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings, such as... Figure 1-3As shown, this utility model provides an aquaculture pond, including an oxygenation mechanism 2 for introducing oxygen into the pond body 1, and a water purification and circulation mechanism 3 for treating wastewater and adding the treated clean water into the pond body 1. The water purification and circulation mechanism 3 includes a wastewater purification device 31, an inlet pipe 32, and an outlet pipe 33. The wastewater purification device 31 is located on one side of the pond body 1 and includes a wastewater sedimentation tank 311, an inlet 3111 on the wastewater sedimentation tank 311, a wastewater filter tank 312 located below the wastewater sedimentation tank 311, and a filter screen 3121 inside the wastewater filter tank 312. The wastewater sedimentation tank 311 and the wastewater filter tank 312 are connected by a pipe. One end of the inlet pipe 32 is connected to the pond body 1, and the other end of the inlet pipe 32 is connected to the inlet of the inlet pump 34. The outlet of the inlet pump 34 is connected to the wastewater sedimentation tank 312. The water filter tank 311 is connected, one end of the outlet pipe 33 is connected to the sewage sedimentation tank 312, and the other end of the outlet pipe 33 is connected to the inlet of the outlet pump 35. The outlet of the outlet pump 35 is connected to the aquaculture tank body 1. A solenoid valve can be installed in the pipe to prevent the agent from entering the sewage filter tank 312 due to insufficient reaction. The aquaculture sewage is pumped into the sewage purification device 31 through the inlet pump 34. Sedimentation agent and disinfectant are added into the sewage sedimentation tank 311 through the dosing port 3111. The sewage impurities are deposited and disinfected in the sewage sedimentation tank 311. Then, the sewage is filtered through the filter screen 3121 in the sewage filter tank 312. The sewage in the aquaculture tank body 1 is disinfected, settled, and filtered. The sewage discharged from the aquaculture tank body 1 is purified, and the purified water is pumped into the aquaculture tank body 1 through the outlet pump 35 to realize the purification and circulation of water and reduce the waste of water resources.

[0020] The wastewater sedimentation tank 311 of this utility model is also provided with a stirring assembly 4. The stirring assembly 4 includes a stirring shaft 41 rotatably disposed in the wastewater sedimentation tank 311, stirring blades 42 disposed on the stirring shaft 41, and a stirring drive motor 43 disposed on the wastewater sedimentation tank 311. The power output end of the stirring drive motor 43 drives the stirring shaft 41 to rotate in the wastewater sedimentation tank 311, thereby accelerating the reaction of the disinfection and sedimentation agent added from the dosing port 3111 and improving the purification efficiency.

[0021] The filter screen 3121 of this utility model has two layers, and both layers of filter screen 3121 are detachably installed inside the sewage filter tank 312. The double-layer filtration ensures the filtration effect. The filter screen 3121 of this utility model can be set as a polyester filter screen or an activated carbon filter screen. Different filter screens can be selected as needed to ensure the filtration effect. The filter screen is detachably installed inside the sewage filter tank 312 and can be removed for cleaning, which is convenient for use. The sewage filter tank 312 is also provided with a filter screen removal door 3122. The filter screen removal door 3122 is sleek and sealed on the sewage filter tank 312. However, when it is necessary to clean or replace the filter screen, the filter screen removal door 3122 can be opened for operation.

[0022] The bottom of the wastewater sedimentation tank 311 of this utility model is provided with an isolation element 5. Several isolation elements 5 are provided and are evenly arranged on both sides of the inlet of the pipe. The isolation elements 5 isolate the treated and stratified aquaculture wastewater. The settled impurities will not be stirred back into the treated water body due to the suction of the outlet pump 35. In this embodiment, the cross-section of the isolation element 5 is trapezoidal and narrow at the top and wide at the bottom. A sedimentation tank 51 is formed between two adjacent isolation elements 5. The settled impurities accumulate in the sedimentation tank 51. Because the sedimentation tank 51 is wide at the top and narrow at the bottom, the pressure is increased, and the deposited impurities are difficult to be sucked out, thus preventing the water body from being stirred up. When not in use, the isolation elements 5 can be directly rinsed to prevent excessive accumulation of impurities.

[0023] The oxygenation mechanism 2 of this utility model includes an oxygenation pump 21 and an air pipe 22. The oxygenation pump 21 is located on one side of the aquaculture pond body 1. One end of the air pipe 22 is connected to the outlet of the oxygenation pump 21, and the other end of the air pipe 22 extends into the aquaculture pond body 1. The oxygenation pump 21 fills the water in the aquaculture pond body 1 with oxygen through the air pipe 22, thereby increasing the oxygen content of the water and providing a suitable environment for aquaculture.

[0024] The present invention provides escape-proof nets 6 at the connection points between the water inlet pipe 32, the water outlet pipe 33 and the aquaculture pond body 1 to prevent the aquatic products from escaping from the water inlet pipe 32 and the water outlet pipe 33.

[0025] The bottom of the aquaculture pond of this utility model is provided with a sewage pipe 7 in the middle. The sewage pipe is equipped with a solenoid valve 71. The sewage pipe 7 can discharge the aquaculture waste, feces and other water that are difficult to clean and purify and are deposited at the bottom of the aquaculture pond body 1. The solenoid valve 71 controls the opening and closing of the sewage pipe 7.

[0026] In another embodiment of this utility model, multiple aquaculture pond bodies 1 are provided, and all multiple aquaculture pond bodies 1 are connected to the sewage purification device 31. By providing multiple aquaculture pond bodies 1, a large number of aquatic products can be raised at the same time, or different varieties of aquatic products can be raised separately, thereby improving aquaculture output and efficiency.

[0027] Of course, the above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
