Abstract

The utility model provides a blowdown box with a net, the great dead fish of volume is all concentrated and sinks the collection on the bottom filter of the dirty case of first collection in this decontaminates the box with a net, it collects to ooze last sinking at the dirty bottom of the case of back taper collection in the less hole that can follow on the filter of faecal volume of incomplete bait and fish, die the first drain of fish through the dirty case lateral wall of first collection in first blow off pipe is taken out the box with a net by the water pump, the excrements of incomplete bait and the fish second drain through back taper collection dirty bottom of the case portion is in the second blow off pipe is taken out the box with a net by the water pump, thus, the dead fish in the box with a net has not only been realized to this box with a net, the excrement of incomplete bait and fish is concentrated and is discharged, incomplete bait and excrement and the bulky dead fish separation that can also the make little volume box with a net of separately discharging, save the staff and separated the work of box with a net discharge thing once more.

Description

A kind of blowdown net cage
Technical field
The utility model relates to fishery cultivating apparatus field, more specifically, relates to a kind of blowdown net cage.
Background technology
Existing aquiculture net cage, all be suspended in water by floating thing, four limits suitable for reading of net cage are closely connected with floating thing, four support bars are stretched out in its four angles water, be bundled into a cube with the support bar of four at the bottom of case, place mesh sheet all permeable fish culture net cage in a four sides and bottom. the width of mesh of mesh sheet is determined by supported aquatic animal seed size.Therefore, when throwing something and feeding bait to the aquatic animal of culture in enclosure, the bait of some surpluses and the excreta of aquatic animal are deposited to the bottom by case spacer screen eye, accumulate over a long period, the precipitum of alluvial is more poly-more, and because of they be all the organic substance being rich in nutrition, very easily rot at the bottom smelly, severe contamination water quality. if any fluctuation, water quality around net cage just becomes mixed fouling, affect aquatic animal normal growth and the inherently safe of culture in enclosure, Here it is so-called " self-pollution ", by even dead for the disease that aquatic animal occurs time serious, also likely cause the Disaster And Prevention Measures of Red Tides of greater coasting area.
Utility model content
The utility model provides a kind of blowdown net cage, and this net cage can make the dead fish in net cage easily, the excreta of residual bait and fish is concentrated and discharged, and the residual bait of small size and excreta can also be made to be separated to separate with the dead fish of large volume and to discharge net cage simultaneously.
In order to reach above-mentioned technique effect, the technical solution of the utility model is as follows:
A kind of blowdown net cage, comprise net cage frame and etting, the first sludge collecting box is provided with bottom etting, it is a filter bottom first sludge collecting box, first sludge collecting box sidewall offers the first sewage draining exit, first sewage draining exit place connects one end of the first blow-off pipe by the first flexible connection head, and the other end of the first blow-off pipe extends upwardly to net cage frame and is fixed on net cage frame by the first bindiny mechanism; Back taper sludge collecting box is connected under filter, the second sewage draining exit is offered at the cone top of back taper sludge collecting box, second sewage draining exit place connects one end of the second blow-off pipe by the second flexible connection head, and the other end of the second blow-off pipe extends upwardly to net cage frame and is fixed on net cage frame by the second bindiny mechanism; First blow-off pipe is fixed on one end on net cage frame and the second blow-off pipe and is fixed on one end on net cage frame for being connected aspirator.
Preferably, be fixed on one end on net cage frame and the second blow-off pipe to be fixed on the aspirator that the one end on net cage frame is connected be water pump with described first blow-off pipe.
Preferably, described first blow-off pipe and the second blow-off pipe are all pvc pipes.
Preferably, described first bindiny mechanism and the second bindiny mechanism are all buckles.
Compared with prior art, the beneficial effect of technical solutions of the utility model is:
In decontamination net cage of the present utility model, the dead fish that volume is larger all concentrates heavy collection on the bottom filter of the first sludge collecting box, the excremental small volume of residual bait and fish can ooze out the last collection that sinks at the bottom of back taper sludge collecting box from the hole filter, dead fish is extracted net cage in through the first blow-off pipe by water pump by the first sewage draining exit of the first sludge collecting box sidewall, the excreta of residual bait and fish is extracted net cage in through the second blow-off pipe by water pump by the second sewage draining exit bottom back taper sludge collecting box, like this, this net cage not only achieves the dead fish in net cage, the excreta of residual bait and fish is concentrated and is discharged, the residual bait of small size and excreta can also be made to be separated to separate with the dead fish of large volume and to discharge net cage, save the work that staff is separated net cage effluent again.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent;
In order to better the present embodiment is described, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product;
