Abstract
The invention relates to filtration devices, in particular to an egg membrane removal filtration device for a fish artificial propagation hatching process for solving the problems that meshes are blocked by broken egg membranes and accordingly a hatching bucket overflows and fry escapes due to the fact that a bolting-silk screen is used for filtration and fry collection in a fish egg hatching process as well as broken egg membrane are left in a hatching unit and the deterioration of the water quality and the decreasing of the fry survival rate are caused accordingly when the recycled water is used for hatching in early fish propagation. The egg membrane removal filtration device for the fish artificial propagation hatching process comprises a filter tank, a water collection bucket and a screen barrel. The filter tank is rectangular and arranged below a water outlet of the hatching unit. A water inlet of the water collection bucket is in communication with an overflow opening of the filter tank. The screen barrel is arranged in the water collection bucket and in communication with the overflow opening. The egg membrane removal filtration device for the fish artificial propagation hatching process is used for filtering broken egg membranes produced in the fry hatching process.
Description
Technical field
The present invention relates to a kind of filter, be specifically related to the filter removing egg membrane in a kind of artificial propagation of fish hatching process, belong to aquatic products field.
Background technology
The artificial incubation majority of large fresh-water fishes such as green grass or young crops, grass, silver carp, flathead all adopts hatching pail, circular hatching channal, hatching cylinder etc. to carry out Lotic hatching.When development of fertilized ova is to soon rupture of membranes, will secrete a large amount of enzeons and impel egg membrane to break, fry will hatch out.Emerge this stage at rupture of membranes, because the egg membrane of fragmentation is comparatively light, egg membrane can stir with fry together along with current.Fry is obtained in order to collect, people usually can use bolting silk net to be blocked in incubator by fry, a large amount of broken egg membranes is also blocked in bolting silk net by this method simultaneously, and the mesh of bolting silk net easily blocks by the egg membrane of fragmentation, incubator middle water level is caused to go up until overflow, fry is also flowed out together along with the current overflowed, and fry escape economic benefit is reduced; In fish early numerous use recirculated water hatching, broken egg membrane is stayed in incubator, water quality also can be caused to degenerate problem that survival rate of fish fry reduces.
Summary of the invention
The present invention uses bolting silk net filtration to collect fry to solve, and broken egg membrane can be caused to block mesh, cause hatching pail spilling water fry to escape; At fish early numerous use recirculated water hatching, broken egg membrane is stayed in incubator, water quality can be caused to degenerate problem that survival rate of fish fry reduces, and then proposes the filter removing egg membrane in a kind of artificial propagation of fish hatching process.
The present invention is the technical scheme taked that solves the problem: the present invention includes lautertuns, ponding bucket and net cylinder, lautertuns is rectangle cell body, lautertuns is arranged on the below of incubator discharge outlet, the water inlet of ponding bucket is communicated with the overfall of lautertuns, net cylinder is arranged in ponding bucket, and net cylinder is communicated with overfall.
The invention has the beneficial effects as follows: emerge the stage at fertilized egg rupture of membranes, the bolting silk net of the fry of blocking of hatching pail, hatching cylinder can be taken away, allow fry and broken egg membrane flow in lautertuns simultaneously, because of space and the volume increase of lautertuns, current will slow down slack-off, broken egg membrane due to gravity precipitable in lautertuns, and fry can freely move about, enter into the net cylinder in ponding bucket along with current, so just film is incubated in fragmentation and fry is separated.The present invention can decrease the human cost of incubator bolting silk net cleaning, reduces production risk coefficient, avoids the phenomenon of a large amount of fry death because water quality degenerates.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention, and Fig. 2 is the vertical view of lautertuns.
Embodiment
Embodiment one: composition graphs 1 and Fig. 2 illustrate present embodiment, the filter removing egg membrane in a kind of artificial propagation of fish hatching process described in present embodiment comprises lautertuns 1, ponding bucket 2 and net cylinder 3, lautertuns 1 is rectangle cell body, lautertuns 1 is arranged on the below of incubator discharge outlet 6, the water inlet of ponding bucket 2 is communicated with the overfall 1-1 of lautertuns 1, net cylinder 3 is arranged in ponding bucket 2, and net cylinder 3 is communicated with overfall 1-1.
Embodiment two: composition graphs 1 and Fig. 2 illustrate present embodiment, lautertuns 1 inner bottom surface removing the filter of egg membrane in a kind of artificial propagation of fish hatching process described in present embodiment is equidistantly provided with multiple obstruct rod 4 along lautertuns 1 length direction, and each intercept rod 4 center line along its length all with lautertuns 1 centerline parallel in the width direction, lautertuns 1 inner bottom surface is divided into multiple groove 5 by multiple obstruct rod 4.
The technique effect of present embodiment is: so arrange, multiple obstruct rod 4 can slow down the water velocity in lautertuns 1, and multiple obstruct rod 4 can stop broken egg membrane step by step, because egg membrane is lighter, first intercepts the excellent 4 broken egg membranes do not stopped, and second, third intercepts rod 4 and can be blocked successively; In addition, multiple intercept rod 4 broken egg membrane be evenly distributed on the bottom of lautertuns 1, make broken egg membrane can not in local accumulation.Other composition and annexation identical with embodiment one.
Embodiment three: composition graphs 1 and Fig. 2 illustrate present embodiment, the degree of depth removing each groove 5 of the filter of egg membrane in a kind of artificial propagation of fish hatching process described in present embodiment is 2cm ~ 3cm.Other composition and annexation identical with embodiment two.
Operation principle
Will emerge the stage by rupture of membranes in fertilized egg, reduce the inflow in incubator, ensure that fish-egg does not overflow, at this moment the bolting silk net at incubator discharge outlet 6 place is removed, broken egg membrane is made to flow in lautertuns 1 together with fry, water velocity in lautertuns 1 slows down slack-off, broken egg membrane and length have the dead ovum of water mold can sink on the inner bottom surface of lautertuns 1, fry can freely move about in lautertuns 1, and the net cylinder 3 entered via overfall 1-1 with current in ponding bucket 2, complete filtration and the collection of fry.
