Face is without component, and accidental impact protrusion leads to injury when can avoid fish locomotion；Cultivate the depth in cabin, diameter proportion be 1:1~
1:3 does not generate adverse effect to hull principal dimension, has ensured the navigation performance of ship；If continuing to use the depth of continental rise 1:3~1:5
Diameter ratio is spent, if only arranging one layer of cultivation cabin, will lead to hull flattening, ship resistance increases, and overall longitudinal strength of hull is difficult
To guarantee；If arrangement two or more layers cultivate cabin up and down, it is excessive to will lead to interlayer space, and capacity utilization is caused to reduce；It supports
The inner surface spray coating heat preservation layer for growing cabin is conducive to maintain cultivation cabin water temperature；The hanging walking that is surrounded by cultivation cabin 10 is put down
Platform 11 had not only facilitated personnel's passage, daily maintenance inspection, but also has been not take up cultivation volume；Cultivating bilge portion has centainly centripetal
Gradient, cultivating inside cabin is space for cultivation.
Cultivate and be respectively equipped with water inlet at four ends angle in cabin 10, connect a water inlet pipe 12 on water inlet, water inlet pipe and into
Supply mains 130 connects；The bottom center for cultivating cabin is equipped with water outlet, and there are two the water outlets of exhalant canal for one tool of water outlet connection
Pipe 13；Water inlet pipe 12, outlet pipe 13 are cylindrical；The outer wall of the upper end closed of water inlet pipe, water inlet pipe is perpendicular equipped with being arranged in
The water flow in the hole of row, water inlet is injected into cultivation cabin by this some holes with certain flow velocity, and water inlet pipe can be revolved around its center line
Turn, to change the angle of water inlet injection, achievees the purpose that adjust flow velocity in cultivation cabin；The upper end closed of outlet pipe, outlet pipe
Upper end outer wall is equipped with several uniformly distributed circular apertures, the outflow for water at the middle and upper levels；The lower end outer wall of outlet pipe is equipped with one
The water outlet of a annular, the outflow for bottom water；Bottom water contains more solid particulate matter, through residual bait feces separator
After 110 remove the excrement residual bait of bulky grain, Microfilter 80 is combined into outflow water at the middle and upper levels；Through water inlet pipe and outlet pipe
Cooperation, horizontal main ring stream and vertical circulation can be formed in cultivation cabin, be conducive to growth and the solid of swim fish
The discharge of grain object.
Circular water treating system includes biofilter, CO2Deaerator 40, ultraviolet ray disinfector 50, oxygenation cone 60, circulation
Pump 70 and catch basin；CO2Deaerator 40, ultraviolet ray disinfector 50, oxygenation cone 60, circulating pump 70 setting cultivation cabin 10 with
The adjacent other side in biofilter；Catch basin is arranged in CO2The lower section of deaerator, ultraviolet ray disinfector, oxygenation cone, circulating pump,
Catch basin sucks water body for circulating pump 70, and circulating pump is two, the import of outlet and the oxygenation cone 60 of one of circulating pump 70
The outlet of connection, oxygenation cone 60 is connected to water inlet manifold；The outlet of another circulating pump is connected to water inlet manifold.
The side in cultivation cabin 10 is arranged in biofilter, and biofilter is by the first biofilter 20 and the second biofilter
30 compositions, are separated between the first biofilter 20 and the second biofilter 30 by watertight plate 120, watertight plate is close at bottom of pond
It is provided with several through flow holes；The top of first biofilter 20 is equipped with several Microfilters 80, and the quantity of Microfilter is according to the actual situation
Depending on, the mesh size of Microfilter is about 30-90 μm, and after filtering out most of solid particulate matter by Microfilter, water flow is in gravity
Effect is lower to enter the first biofilter；The side of Microfilter is equipped with residual bait feces separator 110, flows for handling from cultivation cabin
Fraction contains the water of more solid particulate matter out, and treated, and water inflow Microfilter further removes the smaller solid of diameter
Particulate matter；First biofilter 20 is mainly used for removing BOD, and the second biofilter 30 is mainly used for removing TAN；Biofilter
In be filled with filtrate, pack completeness is about 40%-60%, and the bottom of biofilter is evenly equipped with aeration tube 90, aeration tube 90 and blower
100 connections, blower makes water body and filtrate in biofilter acutely roll through aeration tube input air, accelerate BOD, TAN and
The mixing of filtrate, oxygen improves reaction rate.
After biochemical reaction, water flow is flowed out from the upper surface of the second biofilter 30, into CO2Deaerator 40.
Water flow flows through CO from top to bottom2Deaerator 40, air-flow flow through CO under the action of blower from the bottom up2Deaerator 40,
Air water forms convection current, excessive CO in water flow2It is diffused into air, to be removed.
Next water flow flows through ultraviolet ray disinfector 50, the microorganism in water is killed.
Water flow is then sucked by two circulating pumps 70 (axial-flow pump), and the outlet of a circulating pump 70 (axial-flow pump) is connected to increasing
The outlet of the import of oxygen cone 60, oxygenation cone 60 is connected to water inlet manifold 130；The outlet of another circulating pump (axial-flow pump) pump is direct
It is connected to water inlet manifold；When First recycles failure of pump, second circulating pump can be switched to the state to supply water to oxygenation cone 60, mention
High redundancy and reliability；1-4 root branch pipe is outputed on water inlet manifold, is connected to corresponding cultivation below the bottom plate in cultivation cabin
Water inlet pipe in cabin, to complete a circulation.
Boat-carrying circulating water culture system of the present invention with links also in it can be equipped with various sensor monitoring water bodys
CO2Concentration, oxygen concentration, ammonia nitrogen concentration, nitrate, nitrite nitrogen concentration, pH value, water temperature, flow velocity etc., when some water
When matter parameter drift-out setting range, system being capable of adjust automatically pump flow, fan delivery, water inlet pipe spray angle, oxygen
The equipment operating parameters such as flow, new water supplement flow, so that regulating water quality parameter, is returned in setting range.
Water level in cultivation cabin is slightly above the water level of biofilter, the water inlet pipe position of Microfilter and the water of biofilter
Position maintains an equal level, and the height of the overflow port of residual bait feces separator is raw higher than the water inlet pipe height of Microfilter lower than cultivation cabin water level
The water level in object filter tank is higher than CO2Deaerator, CO2The installation site of deaerator is higher than the catch basin where circulating pump, above-mentioned height
Arrangement flows water flow under gravity.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The skill of the industry
Art personnel it should be appreciated that the present invention is not limited to the above embodiments, the above embodiments and description only describe
The principle of the present invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, this
