Abstract
The invention discloses a liquid oxygen application synergism device for an industrial aquaculture. An artesian water pipe is additionally arranged at a liquid oxygen oxygenation terminal, namely a nano disc, by utilizing an existing high-level water tank and a water inlet pipeline in the industrial aquaculture; the tail end of the water pipe is hotly pressed into a duck mouth shape; a gas-water mixing region is formed by a horizontal artesian water flow and an upward pure oxygen micro-bubble flow released by the nano disc through adjusting the flow speed of the water flow through a valve; and an annular flow is formed in a culture pond by a mixed flow. The liquid oxygen application synergism device disclosed by the invention not only can be used for solving an oxygen escaping phenomenon due to partial oxygen super-saturation caused by the condition that in a traditional liquid oxygen oxygenation method, the oxygen is at a static water state and the water in the culture pond is too shallow; and the problem that an oxygen dissolving condition is not balanced in the culture pond is solved. The liquid oxygen application synergism device guarantees a high oxygen dissolving state of all water body in the culture pond, so that the feeding efficiency and digesting efficiency of aquatic livestock are improved, the growing speed is improved by 20% and the cultivation yield is improved by 30%.
Description
[technical field]
The invention belongs to the bleeding technique field, relate to a kind of enhancing device that is applied to liquid oxygen oxygenation in the aquatic products industrial aquaculture.
[background technology]
In the aquaculture; Dissolved oxygen is the key factor that influences fishes and shrimps food ration, growth rate, feed coefficient and health status; Show that according to interrelated data fish are at the feed coefficient of fish during in dissolved oxygen 3 mg/litre, increase during than 4ppm and be twice; Being grown in the long velocity ratio of sashimi (raw fish) among the dissolved oxygen 7ppm, to be grown in fish among the dissolved oxygen 4ppm fast 20%～30%, and feed coefficient low 30%～50%.When the dissolved oxygen in water amount reaches 4.5ppm when above, the appetite of fish strengthens very obvious.For this reason, regulation in China's " water quality standard for fishery ": the dissolved oxygen of breeding water (DO) must have that the time should remain on 5mg/L at least more than 16 hours in one day 24 hours, must not be lower than 3mg/L any time.
In the industrial aquaculture; Because of phytoplankton quantity in the water seldom, pond oxygen in water main source is an artificial oxygenation, present mode mainly contains two kinds; One of which is that Roots blower cooperates gas stone that airborne oxygen is dissolved in the water; When the density of fish in the fishpond was big, dissolved oxygen amount generally had only about 5.0ppm, can not reach the fish requirement of growing fast; Its two be with pure oxygen liquefaction back through oxygen container, oxygen channel, pressure regulator valve, nanometer gas stone etc., oxygen molecule is distributed to Chi Shuizhong equably, the fishpond dissolved oxygen amount rises to about 10.0ppm; Growth rate of fish and output can increase greatly, but because of the pure oxygen microbubble can be diffused in the air in hydrostatic very soon, have caused the waste of liquid oxygen resource; That is to say; Present liquid oxygen application mode is not brought into play the liquid oxygen oxygenation effect fully, has fully mixed problem of liquid oxygen and water.
[summary of the invention]
The objective of the invention is, design a kind of raising liquid oxygen oxygenation efficient, and simple, the easy to operate liquid oxygen enhancing device of equipment.
The present invention realizes through following method: utilize head-tank and inlet pipeline in the industrial aquaculture; Set up a gravity flow water pipe at nanometer plate place, liquid oxygen oxygenation terminal----; The water pipe end is hot pressed into duckbill, through the flow velocity of valve regulated water, and the pure oxygen microbubble that the makes progress stream that the gravity flow current of level and nanometer plate discharge; Form the mixed district of air water, the mixed flow of then the two forms circulation in culturing the pond.
The invention has the beneficial effects as follows: the liquid oxygen enhancing device is as the mixing apparatus of liquid oxygen and breeding water; The oxygen that has not only solved in traditional liquid oxygen oxygenation way escapes phenomenon because of what hydrostatic state and the shallow partial oxygen supersaturation that causes of culturing pool produced; Solved the unbalanced problem of dissolved oxygen situation in the breed pond; And through circulating water flow, the discharge outlet at breed center, pond forms the accumulation regions of residual bait, ight soil, has solved the problem that dirt disperses difficult discharge in traditional breed pond.The present invention has guaranteed to culture the high dissolved oxygen state of whole water bodys in the pond, therefore can improve grazing rate and the digestibility of aquatic livestock, has not only improved growth rate, and has improved cultured output.

Figure of description is that the industrial aquaculture liquid oxygen is used the enhancing device structural representation.
Among the figure: 1--liquid oxygen pipe, 2--water nozzle holder, 3--water nozzle fixed band, 4--gravity flow water pipe, 5--duck shape water nozzle, 6--nanometer plate, 7--nanometer pan arrest, 8--nanometer plate groove.
[embodiment]
Be described in detail the structure and the method for using of liquid oxygen enhancing device of the present invention below:
This liquid oxygen enhancing device is to be made up of liquid oxygen pipe, water nozzle holder, water nozzle fixed band, gravity flow water pipe, duck shape water nozzle, nanometer plate, nanometer pan arrest, nanometer plate groove.Duck shape water nozzle is formed by the terminal hot pressing of gravity flow water pipe; And be fixed on the water nozzle holder with the water nozzle fixed band; The water nozzle holder is to be embedded in to mould on the plate pedestal with the corrosion resistant wooden unit to form, and artesian water flows into through moulding pipe by culturing the high-order pond of factory automatically, forms vertical mixed flow with oxygen flow; Then, mixed flow forms horizontal circulation in culturing the pond.The liquid oxygen pipe links to each other with nanometer plate; Be fixed by bolts to by moulding on the nanometer plate groove that plate is welded, nanometer plate embeds with moulding in the nanometer pan arrest that plate makes, and oxygen flow forms the vertical instant district of mixing with automatic current; Then, mixed flow forms horizontal circulation in culturing the pond.General fixing 2 nanometer plate in the nanometer plate groove.
Concrete operations are following: according to raising fish and shrimp area and cultivation density, the liquid oxygen storage tank of respective volume is set; Liquid oxygen is moulded the pipe classification by the reinforcement of the plastic-aluminum pipe of 15mm and 5mm and is transported to each and cultures in pond, and the terminal connects this liquid oxygen enhancing device, and the size of air-flow and current is controlled respectively with manometer and valve.Every 50m
2Culture the pond one cover liquid oxygen intensifier can be installed.
2010, prosperous Yongfeng, Tianjin aquaculture Co., Ltd uses this device, and to carry out the cynoglossus semilaevis cultivation effect remarkable.The liquid oxygen tank volume of installing is 15m
3, can store up 13 tons of oxygen, can satisfy 132 7000m altogether
2Culture 1.5 months the dissolved oxygen demand in pond, dissolved oxygen can remain on about 9ppm, and fish loading amount is 200 tons, and more existing liquid oxygen application mode improves 30%, and the culture-cycle foreshortened to 2 years by 2.5 years, improves and cultures efficient 20%.
