Description
Technical Field
The utility model relates to a water oxygenation or shrimp breed field especially relate to an ejector and efflux formula of high density shrimp culture pond push away water oxygenation system.
Background
The prawn culture has developed into a pillar industry of the aquaculture industry of China, wherein the penaeus vannamei is a main culture variety. However, in recent years, due to the problems of frequent diseases, environmental pollution and the like, the shrimp culture mode in the traditional outer ponds such as the soil ponds and the elevated ponds is greatly reduced in culture area and yield when the shrimps are cultured on the downhill. Meanwhile, an indoor high-density shrimp culture mode is gradually increased, and particularly, a large batch of warm sheds and workshop cement shrimp culture ponds are newly built and modified in Shandong and Bohai sea coastal areas in China.
The indoor shrimp culture pond mainly adopts a square pond, a circular pond and an annular runway pond, and the area of a single pond body is small and generally varies from dozens of squares to dozens of squares; but the density of the shrimp fries bred is very high, generally in 300-1000 per cubic water body, and is far higher than that of an earth pond and an elevated pond. Under the condition of such high-density culture, the continuous and stable supply of dissolved oxygen in pond water is a precondition for ensuring the survival and healthy growth of prawns. The traditional common mechanical oxygen increasing modes such as a waterwheel type oxygen increasing machine, an impeller type oxygen increasing machine, a jet type oxygen increasing machine and the like are suitable for shrimp culture ponds of large water bodies, and the oxygen increasing efficiency is limited; at present, a micropore aeration oxygenation mode is adopted in indoor shrimp ponds more. The microporous aeration oxygenation mode is generally characterized in that an external air blower is used for inflating air and aeration is carried out through aeration stones or aeration pipes which are densely distributed in the shrimp pond, although the oxygen dissolving requirement of the high-density aquaculture water body of the shrimp pond can be met on the whole, the horizontal flow of the water body in the shrimp pond cannot be promoted, and dirt accumulation is easily formed at the local part of the bottom of the shrimp pond to spoil the water quality. Moreover, the aeration stone and the aeration pipe are easy to block or age and crack, the aeration effect is also influenced, and frequent maintenance and updating are needed.
On the other hand, in the high-density culture process, a large amount of feed input in the shrimp pond inevitably generates a large amount of culture wastes such as residual baits and excrement, and the organic wastes not only cause water eutrophication and breeding pathogenic bacteria, but also further decompose and generate harmful substances such as ammonia nitrogen, nitrite nitrogen and the like. Therefore, how to timely and effectively discharge the waste is a key problem to be solved in the indoor shrimp pond, and pollutants are controlled from the source. In the actual production, the sewage suction and discharge are carried out in a manual siphon mode, so that the operation is time-consuming and labor-consuming; the sewage is discharged by adopting a large amount of water changing modes, so that not only is the water resource wasted, but also the external environment is possibly adversely affected. Therefore, a mode capable of promoting the water body to flow and discharging the sewage in a centralized manner needs to be designed to improve the collection capacity and the discharge efficiency of the cultivation waste, which is very important for ensuring the stability of the water quality and improving the cultivation success rate.
The jet aerator is a device which is developed based on the negative pressure jet principle and integrates high-efficiency oxygenation and water flow pushing, is widely applied to the field of water treatment and also begins to be introduced into the field of aquaculture. The prior art discloses an efficient venturi ejector like chinese utility model patent CN204490598U, and its product size is great, and the first minor diameter end diameter of efflux has 20 ~ 30mm, unsuitable small-size water, and the efflux water flows through by force moreover, produces the injury to breeding the shrimp easily. Also, as the chinese utility model patent CN103102021B discloses a high oxygen jet device, which adopts the unique radiation structure of multiple spray guns with small-bore spray heads, and can improve the jet efficiency, but only generates local circulation around the jet device, which is not beneficial to the concentration and discharge of cultivation wastes in the whole cultivation water body. Further, as disclosed in chinese utility model patent CN102887594B, a method and facilities for making a water body flow and increasing oxygen by a plurality of jet devices are disclosed, wherein a water pump, a water pipe network, an air supply pipe, a jet device and the like are all disposed on the water surface or in the water body, and these devices and facilities need to be fixed in the water by buoys and the like, which brings inconvenience to the operation and maintenance. Moreover, when the device and the facility run in a water body, the impact force of water flow generated in the pipeline can abrade or damage a water pipe network or an air supply pipe, and when the water pump is closed and the running is stopped, the culture waste can block the ejector, so that the water body is anoxic, and the culture failure is directly caused.
