Description

A kind of floating flowing water culture sink
Technical field
The present invention relates to a kind of floating flowing water culture sink, specifically by the use of air lift water as major impetus, promotes Current are moved to sink trailing edge, realize that fish excrement, residual bait in collecting dung area precipitation concentration, belong to automatically while oxygenation is realized Technical field of aquaculture.
Background technology
In existing fish cultural technique, generally there are several forms:1, industrial circulating water cultivating pattern;2, traditional pond is supported Grow.1, in industrial circulating water cultivating pattern, generally intake using sink upper end, the water outlet of sink lower end.Each cultivation flume is determined Phase discharges the solidliquid mixture of excrement, residual bait and waste water from bottom, these mixtures focus on the solid-liquid in recirculation system After separator carries out separation of solid and liquid, water quality adjustment is carried out into next link.In general, industrial circulating water cultivating exists Cost is higher, the high inherent defect of operation expense.2, in traditional cultivating pool, planktonic organism is the producer, filter-feeding Fish are consumers, and the microorganism in water body is analyst.Breeding water body be both cultivate object life area and excrement, The decomposition place of residual bait etc., and the culture pond of planktonic organism.The breeding way of this " unification of three ponds ", be easy to cause " consumption Disruption of ecological balance between person, the producer and analyst ".Water body for separation or degrading cultivation object metabolite is very few, leads to It is often particularly evident in high-density breeding pattern, fast growing period, carry out regulating water quality often through refreshing the water periodically.In addition, " three ponds The aquaculture model of unification " also increases management difficulty, and there is an urgent need to a kind of cultivation that different ecological functional unit is independent Pattern, modularization construction is carried out according to different block functions, to improve production and degradation efficiency.
The content of the invention
It is an object of the invention to overcome above the deficiencies in the prior art, and provide it is a kind of it is applied widely, easy to operate, Economical and practical, water stabilization cultivation flume.
The present invention is realized by following technological means:
A kind of floating flowing water culture sink, the sink one end are provided with sink water inlet, and the other end is provided with sink water outlet Mouthful, sink water inlet is opening down, and sink outlet is opening up, and air lift water installations, gas are wherein provided with sink water inlet The pipe that picotan is vertically arranged, the lower end of pipe is air lift water installations water inlet, and upper end is air lift water installations water outlet, pipe Lower part is provided with aeration entrance.
The precipitation tank less than sink bottom surface is provided below in the floating flowing water culture sink, sink outlet.
The floating flowing water culture sink, is provided with hexagon cellular inclined tube above precipitation tank.
The floating flowing water culture sink, sink water inlet are grid-like.
The floating flowing water culture sink, the width of grid are less than 5mm.
The floating flowing water culture sink, sink is segmented, is to be detachably connected between each section.
The floating flowing water culture sink, when air lift water installations carry out aeration water lift, water velocity 0.04m/s.
The water body such as traditional pond or reservoir is entered in cultivation flume by notch of intaking, and is moved by the use of air lift water as main Power, pushes away water installations and promotes current to be moved to sink trailing edge.Since fish have stream habit of tracing back, fish body is in sink upstream, excrement, Residual bait etc. is slowly moved under the action of current to sink trailing edge, is finally precipitated in sink end collecting dung area.Periodically pass through Water pump extracts excrement settling zone excrement, and being used for organic fertilizer after concentrated tower concentration makes.Certain amount is placed in traditional pond This sink, rest surface plants emergent aquactic plant, for being dissolved in the nutriment of water body in sink of further degrading, prevents Water body overnutrition.
Compared with traditional pond cultivates, superiority of the invention is as follows:
(1)The present invention only goes out the total output of traditional pond, remaining 98% water surface with the water surface aquaculture of traditional pond 2% or so For purifying water body, water quality indices qualified discharge, fishing survival dose reduces more than 90%, and flesh quality significantly improves, sink pipe Reason is convenient, and fishing is convenient.
(2)The present invention is since current slow down at sink outlet, and excrement, residual bait deposit in precipitation tank automatically, periodically Extract deposit out cultivation flume, ensure that breeding water body water quality is in high-quality state all the time.After deposit is concentrated, ferment Processing, organic fertilizer is made after dry.
(3)Sink water inlet of the present invention can be arranged to it is grid-like, width be less than 5 millimeters, avoid wild fishes enter cultivation Sink grabs feed, influences cultured fishes and ingests.
(4)Sink water inlet of the present invention can be arranged on below 1.8 meters of the water surface, by extracting water body lower water, into Row aeration, and solar exposure is utilized, help to sterilize, reduce cause of disease.Accelerate the friendship of water body levels by extracting water body lower water Stream, is improved lower water column dissolved oxygen situation.
(5)Sink of the present invention can be segmented, be to be detachably connected between each section, ensure transport and convenient disassembly, and Actual production can suitably increase and decrease sink cultivation segment length according to the specification, size, length of cultured fishes.
(6)Sink water inlet of the present invention is provided with hexagon cellular inclined tube, adds wetted perimeter area, improves sedimentation basin Disposal ability;Shorten particle settling height, so as to shorten the sedimentation time;Increase the desilting area of sedimentation basin, so as to improve Treatment effeciency.
(7)Sink of the present invention integrally uses floating structure, can adapt to any water body of different water depth(Lake, pond, sea Ocean, river etc.), possess broad applicability.
(8)The present invention had both met high-density fish culture dissolved oxygen need by the use of air lift water as the major impetus for promoting water movement Ask, and ensure that current are in flow regime all the time, accelerate water circulation and ammonia nitrogen degradation, be conducive to the fast-growth of fish.
