Abstract

The utility model discloses a filter unit for changing water for aquatic planktonic larvae. The filter unit is characterized by comprising a box body (1); a detachable side filter mesh (2) is sheathed in the box body (1), and the upper part of the side filter mesh (2) is located outside the box body (1); a top filter screen hoop (3) is supported to the top end of the side filter mesh (2); a flexible filter screen (4) is connected with the interior of the top filter screen hoop (3); when the filter screen (4) is in a natural falling state, the bottom end of the filter screen (4) is located within a range from the bottom part of the box body (1) to the mid height of the box body (1). The utility model relates to the filter unit which cannot impact or hurt the planktonic larvae during a water changing process, and is capable of simply and efficiently changing the water for the aquatic planktonic larvae.

Description

Aquatic animal floating larva changes water filtering device
Technical field
The utility model relates to a kind of filter, and particularly a kind of aquatic animal floating larva changes water filtering device.
Background technology
Aquaculture, no matter from fish production total amount, is still taken in and is all demonstrated its more and more consequence from fishery economic.To last century Mo, aquaculture output has accounted for 20 %--25 % of world fisheries gross yield, and its output value may surpass 50% of the gross output value.Along with the increase of aquatic products demand and the stagnation that the world fishes for fishery in recent years, aquaculture is more and more important for the effect of World Water production.
Along with developing rapidly of breeding production, seed produces the great attention that has also been subject to each department, all departments and the producer.Although China seed produces and obtained certain achievement, but still exists some problems, these problems mainly concentrate in the incubation of seed.Seed is very fragile in incubation, is easy to be subject to the impact of bad environmental stimuli, and therefore the impact of especially severe water environment needs many as far as possible and frequently the water in culturing pool changed, and guarantees good water quality.The current water mode of changing is directly with net, to copy the young that accesses filtration at the delivery port of culturing pool, but this extensive water method of changing is easy to cause violent flowing water to impact, and makes the young appearance of outflow extensive injured even dead, thereby reduces the efficiency of cultivation.
Therefore need now a kind of aquatic livestock floating larva that can address the above problem, new to change water filtering device or method.
Summary of the invention
The utility model is in order to solve the existing above-mentioned deficiency of prior art, proposes a kind of changing in water process and can floating larva not impacted and be injured, and can for aquatic livestock floating larva, change simply, efficiently the filter of water.
Technical solution of the present utility model is: a kind of aquatic animal floating larva changes water filtering device, it is characterized in that: described filter comprises box body 1, in box body 1, be socketed with dismountable side screen lattice 2, and the top of side screen lattice 2 is positioned at outside box body 1, apical support at side screen lattice 2 has top filter screen hoop 3, in top filter screen hoop 3, be connected with flexible filter screen 4, filter screen 4 is when naturally drooping state, and the bottom of filter screen 4 is positioned at the bottom of box body 1 to the scope of box body 1 half height.
Compared with the existing technology, tool has the following advantages the utility model:
The aquatic animal floating larva of this kind of version changes water filtering device, it is simple in structure, design ingenious, it is for there is no special-purpose filter in traditional floating larva breeding water body filter process, cause current directly to dragged for the floating larva of interception by net, to impact, cause floating larva a large amount of injured even dead, reduce the problem of cultivation efficiency, design a kind of special structure.It can guarantee in the process of filtering that the floating larva being blocked is always in water, and then avoid the impact that causes because of long-term lack of water, can also play to the current that filter the effect of buffering simultaneously, be that filtered water stream can directly not impacted floating larva, to reduce to change in water process the damage for floating larva.And its manufacture craft is simple, cheap for manufacturing cost, therefore can say that it has possessed multiple advantage, is particularly suitable for applying in the art.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.As shown in Figure 1: a kind of aquatic animal floating larva changes water filtering device, comprise a box body 1 that conduct is basic, at the interior dismountable side screen lattice 2 that are socketed with of endosome 1, and the first half of these side screen lattice 2 is higher than the upper edge of box body 1, apical support at side screen lattice 2 has top filter screen hoop 3, and in top filter screen hoop 3, be connected with flexible filter screen 4, when flexible filter screen 4 is when naturally drooping state, the bottom of filter screen 4 is positioned at the bottom surface of box body 1 and the scope of box body 1 half height.
The course of work that the aquatic animal floating larva of the utility model embodiment changes water filtering device is as follows: the filter of the present embodiment is placed on to the delivery port below of changing water device, before work, case is filled to water body in box body 1, then start and change water device, the floating larva of being gone out by water body can fall into the filter screen 4 in top filter screen hoop 3, because the length of filter screen 4 is longer, can guarantee that the bottom at the effect lower filter screen 4 of water impact is positioned at the latter half of box body 1 all the time, sink under the water surface, therefore floating larva also can be attached to the inner side of filter screen 4 under the effect of current, water body in box body 1 constantly overflows by side screen lattice 2 from the upper edge of box body 1, the filter of this structure both can filter water body, can guarantee that again floating larva can be injured even not dead because being directly subject to water impact.
Filter after a period of time, top filter screen hoop 3 is taken off from side screen lattice 2, by filter screen 4 upsets, allow the floating larva that is attached to filter screen 4 inner sides come back in Cultivation container.
