Aquaculture water circulation system

Abstract

An aquaculture water circulation system is disclosed. The system comprises a culture pond, wherein a filter box and a water storage pond are arranged on one side of the culture pond, pump bodies are arranged between the filter box and the culture pond as well as between the water storage pond and the culture pond, a hollow rotating shaft is rotationally connected to the inner wall of the filter box, and an agent adding opening is formed in one end of the hollow rotating shaft; a filter screen is arranged on one side of the hollow rotating shaft, two throwing plates are fixedly connected to the outer wall of the hollow rotating shaft, a second agent storage cavity is formed in each throwing plate, an inlet is formed in the joint of each second agent storage cavity and the hollow rotating shaft, a one-way valve is arranged in each inlet, and an extrusion plate is slidably connected to the inner wall of each second agent storage cavity. According to the system, a flocculating agent can be automatically thrown into sewage, and can be stirred in the rotating process of the throwing plates, so that the flocculating agent and various impurities in the sewage are fully mixed, fully adsorbed and filtered by the filter screen, and the cleanliness of the sewage after filtration is greatly improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an aquaculture water circulation system. Background technique [0002] Aquaculture is the waters that humans use for breeding (including planting). According to the ecological habits of the breeding objects and the requirements for the environmental conditions of the waters, aquaculture technology and facilities are used to engage in aquatic economic animal and plant breeding. one. According to the nature of the waters, it is divided into marine aquaculture and freshwater aquaculture. [0003] In aquaculture, in order to save water resources, farmers will circulate the aquaculture water, and this method can improve the aquaculture environment, promote the decomposition of organic matter, and clean up the dirt and other garbage impurities in the aquaculture pond. During the water cycle process, there will be After the sewage is extracted, the flocculant is then used to absor...

Problems solved by technology

[0003] In aquaculture, in order to save water resources, farmers will circulate the aquaculture water, and this method can improve the aquaculture environment, promote the decomposition of organic matter, and clean up the dirt and other garbage impurities in the aquaculture pond. During the water cycle process, there will be After the sewage is extracted, the flocculant is then used to absorb various impurities in the sewage. At present, the flocculant is generally thrown down directly, which will cause the flocculant to fail to fully react with the sewage, and cannot fully absorb various impurities, resulting in the failure of the filter to filter. Unclean, so that some harmful substances flow back into the aquaculture pond, causing damage to the aquatic products in it
