Novel pond internal circulating water breeding system

Abstract

The invention discloses a novel pond internal circulating water breeding system. The novel pond internal circulating water breeding system is composed of a breeding pond, a shunting blown-down system,water inflow pipes and a water drain pipe. The breeding pond is a square fillet gradient cement pond. The shunting blow-down system comprises a dirt collecting funnel, a station pipe, a precipitatedparticle channel pipe, a suspended particle channel pipe and a precipitation and filtration pond with a first filtering brush and a second filtering brush. The cement pond water inflow pipes are reversely mounted at opposite corners or on the same sides along the upper edge of the pond. The dirt collecting funnel is arranged in the middle of the bottom of the pond and connected to the precipitation and filtration pond through the precipitated particle channel pipe and connected to the pond through the water drain pipe. Water drain holes are formed in the portions, at the upper end of the dirtcollecting funnel and the upper end and the lower end of a water line, of the station pipe, and the station pipe penetrates through the middle of the dirt collecting funnel and is connected to the pond through the suspended particle channel pipe and the exhaust pipe. The novel pond internal circulating water breeding system is suitable for fish high-density intensive breeding, fish feces and residual feed can be effectively collected, the collecting rate reaches 70% or above, suspended particles in water and oil dirt and foams on the surface can be discharged in time, environmental friendliness is achieved, and the breeding cost is reduced by 10%-30%.

Description

technical field [0001] The invention relates to the technical field of fish farming, in particular to a novel pond circulating water farming system, which can discharge sewage in separate paths and collect feces and residual bait. Background technique [0002] my country is the largest fishery production country in the world, and it is also the only country in the world where aquaculture production exceeds fishing production. This special form of industrial structure and the continuous decline of fishery resources determine that the allocation of fishery production factors and scientific and technological resources in my country will still be dominated by aquaculture for a long time in the future, in order to meet the needs of my country's huge population for aquatic products and Supply, to provide better quality aquatic ingredients to improve the dietary structure. Currently: The pond culture method is still the dominant mode of aquaculture in my country. With the advancem...

Problems solved by technology

However, there are still many deficiencies, such as the feces collection efficiency is not high, no more than 30%, some feces and residual bait are still deposited at the bottom of the culture tank, and the sewage discharge is not complete; the water flow formed by air push causes the cultured fish to top water for a long time A large amount of energy is consumed, which leads to an increase in the feed coefficient and a rise in breeding costs; because the fan of the air-push system introduces a large amount of hot air and pushes the surface water, the water temperature of the aquaculture tank rises significantly in high-temperature seasons, and fish are fed due to high-temperature stress. The amount of water is significantly reduced, and the growth rate is reduced; a single aquaculture tank cannot completely achieve the purpose of cleaning the pond
