Description

Fish industrial aquaculture water circulation system

Technical field

The utility model belongs to the cultivation equipment field, relates to particularly a kind of fish industrial aquaculture water circulation system.

Background technology

Fish industrial aquaculture industry is rapid in development in recent years, becomes the rising industry of aquaculture.But fish industrial aquaculture technology still exists the problem that energy consumption is large, cost is high, becomes one of restrictive factor of the sector development, and the energy-saving and emission-reduction problem that therefore solves in the current breeding process becomes a kind of urgent social demand and the market demand already.

The breeding way that northern China adopts now mainly is that workshop cultivation, plastic tunnel cultivation add the modes such as Insulation, generally adopt the boiler heating seawater, extract underground sea water, utilize the residual heat of electric power plant heating seawater, the means such as solar energy heating seawater raise or reduce the water temperature of indoor temperature and aquaculture water, reach the water environment requirement of cultured fishes.And some famous-brand and high-quality fish are had relatively high expectations to water environment, particularly need running water to cultivate at Seedling Stage, and mass energy has been wasted in boiler heating of seawater and running water discharging, have caused the raising of aquaculture cost and the pollution of a large amount of breeding wastewaters.Present development along with cultural technique, open water circulation aquaculture model is carried out in the fish culture workshop in suitable spring of natural temperature, autumn, need the winter or summer of rising or reduction water temperature to carry out the enclosed water cycling aquaculture model, and then saving aquaculture cost, but because two kinds of cultivation patterns, therefore need two kinds of water circulation systems, not only increased aquaculture cost, and owing to pipe laying has occupied breeding spaces too much.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of fish industrial aquaculture water circulation system, in the industrial aquaculture process, can in a cover water drainage-supply system, realize simultaneously open water circulation aquaculture model and enclosed water cycling aquaculture model by the utility model, solved in the prior art the famous-brand and high-quality fish culture of cultivation workshop two cover water circulation systems have been set, thereby increased aquaculture cost, taken the problem of breeding spaces.

The utility model is achieved by the following technical solution:

A kind of fish industrial aquaculture water circulation system, it comprises culturing pool, horizontal drain pipe, vertical drainage pipe, inner sleeve, blow down branch, reducer pipe, total blow-off pipe, return pipe, water treatment facilities, cistern, water inlet pipe and water inlet pipe, horizontal drain pipe one end is connected with the culturing pool sealed bottom, the other end upwards is connected with the vertical drainage seal of tube by a three-way pipe, the three-way pipe another port is closely inserted reducer pipe butt end opening downwards, reducer pipe taper end opening closely inserts blow down branch, and blow down branch is tightly connected with total blow-off pipe; Inner sleeve is through the vertical drainage pipe, closely insert in the reducer pipe taper end opening its lower end, between inner sleeve and the vertical drainage pipe space is arranged, and inner sleeve is higher than the vertical drainage pipe, so that extract or insert inner sleeve, the return pipe of vertical drainage pipe upper end sidewall and horizontal direction is tightly connected, the return pipe upper wall is apart from the cultivation water level 10-18cm in the culturing pool, vertical drainage pipe top communicates with air, and vertical drainage pipe top is higher than culturing pool, the return pipe other end is connected with water treatment facilities, water treatment facilities is connected to cistern, water inlet pipe one end is connected to cistern, and the other end enters cultivating workshop, is connected on the culturing pool or the culturing pool top by the arm on the water inlet pipe, when inner sleeve is extracted in the reducer pipe taper end opening, breeding water in the culturing pool enters reducer pipe by horizontal drain pipe, then blow down branch flows into total blow-off pipe, and be open water circulation aquaculture model this moment; In the time of in inner sleeve closely inserts reducer pipe taper end opening, after breeding water in the culturing pool enters the vertical drainage pipe by horizontal drain pipe, breeding water upwards flows into return pipe through the space between inner sleeve and the vertical drainage pipe, then enter water treatment facilities, breeding water after the processing enters cistern, enter culturing pool by water inlet pipe, water inlet pipe, be the enclosed water cycling aquaculture model this moment.

The utility model beneficial effect compared with prior art:

The utility model uses a cover water drainage-supply system to integrate open water circulation aquaculture model and enclosed water cycling aquaculture model, thereby has reduced production cost, has reduced the breeding spaces that takies.。

The blow-off pipe operated by rotary motion is underground in the industrial aquaculture workshop, all to open floor drain during each controlled valve, the utility model arranges inner sleeve and replaces the valve of prior art on blow down branch in the vertical drainage pipe, can select different water circulation aquaculture models by the inner sleeve of extracting or inserting in the vertical drainage pipe, easy and simple to handle, quick.
