Description
Technical field
The present invention relates to the structure of a kind of flotation tank, particularly flotation tank, especially relate to seawater and support a kind of improvement structure of processing for airfloat equipment foam in shrimp system.
Background technology
Prawn nutritive value is very high, belongs to high-protein nutrient aquatic products.
Traditional shrimp culture industry has taken large-area waters and land resources, and is easily subject to the impact of natural calamity, causes great economic loss.In breeding process, a large amount of accumulation of harmful substance, have caused huge negative effect to environment, have brought great risk and difficulty also to the development of shrimp culture industry.Under this environment, prawn circulating water cultivation, as because water consumption is few, pollute the advantages such as little, is promoted gradually throughout the country in recent years under the support of governments at all levels and under the cooperation of researcher.
In circulating water culture system, there are a large amount of micro-solids things, remain residual bait, ight soil etc. after being mainly derived from bait throwing in.Their damage shrimp gills, can consume dissolved oxygen during degraded in a large number, affect water quality water colour, are to bring out prawn disease, affect the key factor of prawn health.Therefore, research and the application of breeding water body microparticle removal technology are generally paid attention to.
Airfloat equipment is to utilize air Bubble generating apparatus atomization bubble, and after fully mixing with the waste water elevating, and under the effect of the shearing force of water, gas breaking becomes microbubble and is spread in water, and vertical lifting reposefully in airfloat equipment, forms air supporting.Micro air bubble adheres to the suspended material in water, forms the buoyancy aid floating that proportion is less than water, then is discharged by row's bubble mouthful, thereby completes water purification process.At present, air flotation technology has been successfully applied in shrimp ecosystem, but support in shrimp production and find in reality, there is a problem in the operation of this technology in shrimp ecosystem: due to the different water level of different phase needs of prawn culturing, the variation of shrimp-cultivation pool water level causes the water level in airfloat equipment unstable, exerts an influence to the discharge of bubble.The height of existing air supporting row bubble mouth is fixed, and is difficult to adapt to the actual demand of supporting the variation of shrimp systematic water level.
The method adopting at present mainly contains two kinds:
The one, utilize Slag Scraping Device or scraper plate that foam is scraped to flotation tank end, then discharge by scum pipe.This method is mainly used in field of Environment Protection, although effect is better, structure is comparatively complicated, and equipment operation maintenance high expensive is difficult to adapt to the general lower actual state of aquaculture industry profit.It is example that the cycle water of a water body 100m3 of take is supported shrimp system, and according to production requirement, systemic circulation amount generally will reach 20m3/h, and as standard apolegamy Slag Scraping Device, its power is 0.75kW.The foster shrimp cycle of cycle water is about 120 days, and the system cultivation density while reaching commercial specification is 6kg/m3, therefore, can be calculated the production power consumption that this Slag Scraping Device increases: 0.75 * 24 * 120/ (100 * 6)=3.6 degree/kg commercial sized prawn.In the agriculture electricity rates of 0.4 yuan/degree, every kg commercial sized prawn increases cost 3.6 * 0.4=1.44 unit, and the side of a pond valency of Penaeus Vannmei is about 16 yuan/kg at present, and the use of Slag Scraping Device has increased by 9% aquaculture cost, and shrimp agriculture is difficult to bear.
The 2nd, when air supporting foam is during lower than row bubble mouthful, by artificial use, block bar and drive to sweep and pull out to concentrating place, then give drawing and be transported to outside pond, or adopt heavy caliber flexible pipe, by water pump, be pumped to outside shrimp-cultivation pool.As the method all exists, take a lot of work, time-consuming, energy dissipating, remove the bad result of effect, prawn is supported shrimp family and urgently wishes to make moderate progress.
Number of patent application 201120350326.9 < < vertical lift adjustable weir gate > >, a kind of vertical lift adjustable weir gate is provided, has realized the automation control of weir gate and sewage disposal process middle water level or flow of inlet water and accurately controlled.This weir gate can, according to the requirement of technique inflow, be controlled reductor by the PLC control module of electric cabinet and realize weir gate lifting.This technical scheme can apply to fresh water and support shrimp system, but owing to there is no at present the reductor of seawater corrosion resistance, causes this weir gate to be not suitable for supporting in shrimp system and using at seawater.
Number of patent application 201110255988.2 < < rack-and-pinion adjustable weir gate > >, a kind of effective ways that water level regulates and the automation of weir gate is controlled of realizing are provided, but this technical scheme is also to utilize reductor to realize weir gate lifting, has equally the not problem of seawater corrosion resistance.
Number of patent application 201010248779.0 < < adjustable weir gate for water treatment > >, provide a kind of by regulating gas hood internal gas pressure to regulate weir head water level to control to downstream, weir spilling water and amount and the weir gate device of closing, having structure, operation and adjusting controls simple, machinery-free part and moving component, the advantage that reliability is high, but it requires gas hood to be immersed in swimming up and down, forms sealed air chamber.And the flotation tank of supporting shrimp system only has body inside, pond to have water, cannot form sealed air chamber, do not possess the service condition of this technical scheme.
The patent No. 200920210411.8 < < drainage gate for culture tank > > and number of patent application 201110105038.1 < < staged drainage gate plate for sea cucumber culture pond > >, mainly be to provide the emptying gate of discharge bottom culture water, the bubble that cannot discharge superficial water and float on the water surface, can't resolve the problem of supporting shrimp system flotation tank discharge foam.
As can be seen here, due to the corrosivity of seawater, be adapted at the removal structure that seawater is supported the air supporting foam using in shrimp system, should be simple in structure as much as possible, this not only can improve its applicability in seawater, can also reduce difficulty of processing and cost of manufacture, makes it be more suitable for fish production.
