Description
Technical field
The present invention relates to filter, particularly a kind of freshwater fish seedling hatching water filtering device.
Background technology
Fish is to live in the alternating temperature vertebrate of assisting balance and motion in the water, with gill respiration, with fin throughout one's life.Nearly 3,000 kinds of the existing sea water and fresh water fish of China, wherein fresh-water fishes are about about 1000 kinds; Freshwater fish lives in the fresh water, the physical property of water, chemistry and biologically be directly connected to breeding, growing and existence of fish; Hatch fish roe is the highest to requirements in water quality in the fish life cycle, wherein requirements in water quality is mainly contained: water temperature, dissolved oxygen, pH value, harmful organisms, turbidity; To mainly contain with cyclops and water flea be zooplanktons such as large-scale copepoda, aquatic insect and small fish, the shrimp etc. of representative to harmful organisms in the water; Their normal invasion and attack fish-eggs, fry are bitten or kill a large amount of sons, postlarva, and the hatching of fish and the growth of juvenile fish are caused very big harm; Simultaneously because turbidity contains the mud of subparticle is adsorbed on the fish-egg surface or has just made fish-egg or son, postlarva anoxia asphyxia on the son, the postlarva gill filament of incubation of membrane, being adsorbed on fin ray at mud young, postlarva stage subparticle moves about freely and extremely the fish body, thereby reduce the fry hatching survival rate, influence fish production; Go up the hatching water and mostly make delivery port that sack is enclosed within water pump to reach the purpose of filtration, to guarantee effectively to filter and hatch water consumption with 60 orders-80 purpose nylon-tissue bag screen cloth and produce at present; But because filtering mesh bag influences by the impulse force of water pump water outlet, larva such as the cyclops of less individuality and ovum often have by filter screen, and the time have the situation of filtering mesh bag breakage to take place, and the mud in the turbidity is difficult to be filtered.
Summary of the invention
The purpose of this invention is to provide a kind of freshwater fish seedling hatching and use water filtering device, it has good filter effect, satisfies the requirement of freshwater fish seedling hatching water.
Above-mentioned technical purpose of the present invention is achieved by the following technical programs: water filtering device is used in the hatching of a kind of freshwater fish seedling, comprises the chassis, is located at described chassis and madial wall and lateral wall that can both be permeable; The zone that described madial wall surrounds is arranged in the zone that described lateral wall surrounds; Be filled with between the lateral wall by middle stone and medium coarse sand in described and mix the filter course that forms.
As of the present invention preferred, described medium coarse sand and middle stone layer mix in the 4:6 ratio.
As of the present invention preferred, described madial wall comprises the inner support that arranges at interval, is located at the Intranet sheet on the described inner support.
As of the present invention preferred, described madial wall comprises that also the described inner support of connection is used for the interior firm circle of firm described inner support.
As of the present invention preferred, described lateral wall comprises the support arm that arranges at interval, is located at the external net slice on the described support arm.
As of the present invention preferred, described lateral wall comprises that also the described support arm of connection is used for the outer firm circle of firm described support arm.
As of the present invention preferred, described Intranet sheet is that 16-20 order polyethylene has woven net.
As of the present invention preferred, described external net slice is that 16-20 order polyethylene has woven net.
As of the present invention preferred, described middle stone layer is the building stones that the mine is used with the woollen building that is processed into, and particle diameter is 16-31.5mm; The particle diameter of described medium-sand seam is 0.25-0.5mm.
In sum, the present invention has following beneficial effect: stone and medium coarse sand act as filter medium in the employing, have good filter effect, and the one, the mud that can filter subparticle makes water thorough clearly; The 2nd, can effectively prevent harmful organisms in the sealing, be that zooplanktons such as large-scale copepoda, aquatic insect and small fish, the shrimp etc. of representative enter clean water area as cyclops and water flea.During use the present invention is positioned in the water, upper end of the present invention is exposed to the water surface, water outside the lateral wall then permeates middle stone and the medium coarse sand as filter medium, thereby enter that madial wall surrounds clean water area, and then can extract water in the clean water area as freshwater fish seedling hatching water by water pump.
