Description

A kind of seawater filtering device for rearing larvae

Technical field

The present invention relates to a kind of filter, especially a kind of seawater filtering device for rearing larvae.

Background technology

The domestic producer of growing seedlings all can be used the seawater seed rearing after filtration now, and present producer substantiallyAll adopt husky filter method filtering sea (referring to Fig. 2), first must be seawater by compression pump and water inlet pipe ABe transported to high-order water tower (general highly for more than 10m), seawater, by the adsorption filtration of sand, filters outThe foreign material such as planktonic organism and bacterium in seawater, the potential energy producing by a high position and downcomer B and valve BFlow to cistern below, then be transported in nursery pond by another pressure delivery pump. Will make like thisBecome the cost of enterprise to improve, use inconvenient (sand after filtration must often clean). Simultaneously to producerThere is the requirement of any in geographical position, due to seawater seed rearing generally all by the sea, its geology is softer, generalBe not suitable for making high-order water tower. And adopt novel seawater filtering device for rearing larvae, just do not need high-order water towerEtc. building.

Summary of the invention

Outside the deficiency existing in the problems referred to above, the invention provides a kind of seawater filtering device for rearing larvae.

For achieving the above object, the invention provides a kind of seawater filtering device for rearing larvae, comprise filterMain body, described filter main body comprise dark mud chamber, dark mud chamber bottom be provided with discharge piping,Blowdown piping and be arranged on the permeability cell on top, described dark mud chamber, is provided with on described permeability cellThe ventilative pipe cap matching.

Further, described discharge piping comprises outlet pipe, threeway, valve and filter, described in go outWater pipe is communicated with and threeway is installed in junction by being connected short tube with filter, is connecting the installation of short tube middle partThere is valve.

Further, described blowdown piping comprises blow-off pipe and valve, and blow-off pipe middle part is provided with valve.

Further, described water inlet piping comprises water inlet pipe and valve, and water inlet pipe and dark mud chamber pass throughConnect short tube and be communicated with, and connecting short tube middle part mounted valve.

Further, described dark mud chamber is full-closed structure.

Preferably, described dark mud chamber is stainless steel.

Preferably, described dark mud chamber is three or four.

Compared with prior art, the present invention has the following advantages:

1, the present invention has advantage simple in structure, with low cost, as long as just can in three to four dark mud chambersTo adopt dark precipitation method filtering sea.

2, equipment and building use and maintain very convenient, as long as often open sewage draining valve bleed off bottomSewage.

3, filter effect is better than sand filter method, can prevent that secondary pollution is (because sand filter method ratio is easier to growBacterium, cleans and will cause secondary pollution not in time).

Detailed description of the invention

As shown in Figure 1, the invention provides a kind of growing seedlings with the filter of seawater, comprise filter masterBody, described filter main body comprise dark mud chamber 1,1 bottom, dark mud chamber be provided with discharge piping,Blowdown piping and be arranged on the permeability cell 9 on top, described dark mud chamber, installs on described permeability cell 9There is the ventilative pipe cap 8 matching. Described ventilative pipe cap activity is placed on permeability cell, when water inlet piping is toward blackWhen dark mud chamber adds seawater injection, remove ventilative pipe cap, make dark mud chamber and extraneous atmospheric pressure maintenanceBalance. Simple in structure, easy to use, good filtration effect, low cost and other advantages, the position of outlet pipe existsThe summary high position of baseplane, dark mud chamber, so that the planktonic organism in seawater when water outlet, bacterium and someImpurity is not taken together in bottom, and planktonic organism, bacterium and some impurity of bottom are opened by timingOpening blowoff valve discharges.

Described discharge piping comprises outlet pipe 5, threeway 4, valve 3 and filter 2, described outlet pipe5 are communicated with and threeway 4 are installed in junction by being connected short tube with filter 2, are connecting the installation of short tube middle partThere is valve 3. Filter is fixed on the top of outlet pipe, adopts net purchase shape structure, in general filtering seaImpurity, outlet pipe is 30cm apart from the height on ground, dark mud chamber. Connecting short tube and outlet pipe also canBe overall structure, adopt threeway dismounting easy to connect.

Described blowdown piping comprises blow-off pipe 6 and valve, and blow-off pipe 6 middle parts are provided with valve. In employingState structure and facilitate draining-off sewage.

Described water inlet piping comprises water inlet pipe 7 and valve, water inlet pipe 7 with dark mud chamber 1 by being connectedShort tube is communicated with, and is connecting short tube middle part mounted valve. Adopt said structure fast seawater to be injected intoInside, dark mud chamber.

Described dark mud chamber 1 is full-closed structure. Must not there is the place of printing opacity.

Described dark mud chamber 1 is stainless steel. Dark mud chamber adopts cement to be built into or metal moreMaterial is made, and preferably stainless steel is difficult for getting rusty.

Described dark mud chamber 1 is three or four. Dark mud chamber at least one or more, be preferablyThree to four is best, in the time of work, use the seawater of a dark mud chamber, and allow several in additionIndividual dark mud chamber carries out dark precipitation fully.

When work, add seawater by water inlet pipe 7 toward dark mud chamber 1, remove vent cap 8 simultaneously, protectPressure and the atmosphere demonstrate,proved in dark mud chamber 1 maintain an equal level, and add seawater complete, cover vent cap 8, work as darkIt is dark that mud chamber keeps completely, and now the planktonic organism in seawater and bacterium be due to dark, its breeding speedSpend slack-offly, and dead gradually, precipitation simultaneously, down sinks to the bottom of dark mud chamber simultaneously. Its topFor clean seawater, compression pump is extracted the clean seawater in top out in nursery pond by outlet pipe 5, the dirt of bottomWater flows out by sewage pipe 6, so just completes the process of sea water filter. Quick, mistake simple to operationFilter effective.

Only as described above, be only preferred embodiment of the present invention, is such as familiar with the special of this skillIndustry personage. after understanding technological means of the present invention, natural energy is according to actual needs, in the present inventionInstruction under changed. Therefore all equal variation and modifications of doing according to the present patent application the scope of the claims,Once should still remain within the scope of the patent.
