Description

{High density aquaculture and nutriculture system}

The present invention relates to a culture system for aquaculture and nutrient solution, and it is provided with a nutrient solution cultivation apparatus which is cultivated by sunlight and nutrient solution on a biofloc water tank using a BFT (Bio-floc Technology) By supplying the byproducts discharged from the floc tank to the nutrient solution cultivation apparatus, the undifferentiated protein bubble, which is a byproduct of the BFT, is used as the main fertilizer in the cultivation apparatus, and the water solution cultivation apparatus Density eco-friendly aquaculture and nutrient solution cultivation system which is operated by minimizing the facility cost and external power by making the sunlight shroud.

Bio-floc technology refers to the state where microbial bacteria reproduce in a large quantity and become like fluffy, and the technique of culturing using the bio-floc instead of the refinement alga Is referred to as BFT.

These BFTs have the advantage of allowing biofloat to occur naturally or artificially in a culture hog or aquarium, which is more stable and can be maintained unchanged compared to algae-dependent aquaculture.

When bacteria multiply and accumulate in large quantities, they become like fluffy fluffs, which are called flocs.

Flocs decompose nitrogenous wastes due to large amounts of shrimp feces and feedstuffs 10 to 100 times faster than algae, which not only act as day and night, but are also unaffected by weather, decompose nitrogenous wastes In addition, high-protein shrimp feeds are also high.

Recently, these bio-flocs have been applied to the forms of mudfish as well as shrimp by utilizing the bio-floc.

However, such a bio-floc culture method usually requires a filtration facility to prevent inflow of disease sources.

In addition, since the water temperature of the water must be maintained at 30 ° C or more, conventionally, there is a problem that the water heating equipment requires a lot of facilities and costs when it is not a country having a relatively high temperature such as a subtropical climate.

In addition, there was a difficulty in management because the water circulation and disinfection inside the water tank should be performed smoothly, which is a method of using water other than water.

As described above, in the technique relating to the supply and circulation of oxygen in the water tank, the "underwater air bubble induction device" (Korean Patent Registration No. 10-0840623, Patent Document 1), a plate is arranged in a zig- A technique has been disclosed in which sufficient oxygen is supplied to the water in the water tank so that the generated bubbles can be levitated as slowly as possible while being led zigzag by the plate.

However, in Patent Document 1, there is a problem in that a plate provided for inducing bubbles restricts the movement of fishes in a water tank, and a facility and a process are required for washing a greenhouse or a moss with a plate attached thereto .

In order to overcome such a problem, a multi-functional sintering material micro bubble generator for filtration bottle equipped with a bubble diffusion induction plate (Korean Unexamined Patent Application Publication No. 20-2010-0009141, Patent Document 2) By providing a photographic guide plate, the diffusion of bubbles generated through the inclined guide plate is induced.

Patent Document 2 is advantageous in that the bubbles are uniformly diffused in the water tank by the induction plate provided with the multi-layered radiating acid, but since the movement of the bubbles rising rapidly to the upper part of the water tank can not be suppressed, There is a problem that can not be done.

On the other hand, in the "fine bubble supplying device and fine bubble supplying method for supplying bubbles" (Korean Patent Registration No. 10-1009690, Patent Document 3), in the case of fine bubbles having smaller particles than large bubbles, A technique of supplying minute bubbles into a water tank by utilizing the fact that the amount of dissolved oxygen can be increased due to the increase of the amount of dissolved oxygen is disclosed.

In the case of Patent Document 3, it is helpful to increase the amount of dissolved oxygen. However, such minute bubbles must be spread and supplied uniformly in the water tank, and a separate circulation device must be provided for this.

In addition, the BFT has to minimize the inflow of sunlight, which requires the installation of a shoehorn, and has a problem in that the undifferentiated protein bubble, which is a byproduct generated in the aquaculture process, must be filtered.

Hereinafter, the eco-friendly high density culture system and the nutrient solution cultivation system of the present invention will be described in detail with reference to the accompanying drawings.

The eco-friendly high density culture and nutrient solution cultivation system of the present invention includes a biofloq water tank 100, a heating device 200, an oxygen supply device 300, a nutrient solution cultivation device 400, a byproduct treatment and supply device 500, .

The biofloc water tank 100 is installed in the greenhouse 600 to store water therein, such as a water tank used in a known biofloc farm.

In the present invention, a nutrient solution cultivation apparatus 400 is installed in an upper part in place of a separate winging film or cover to allow the nutrient solution cultivation apparatus 400 to completely or partially absorb sunlight As shown in FIG.

As shown in the figure, a heat exchanger 110 is installed in the biofloct water tank 100. One side of the heat exchanger 110 is connected to a pipe through which the heating device 200 and the heating medium are introduced and discharged, Is formed with an inlet and an outlet through which the water in the water tub (100) flows in and out.

The heat exchanger 110 has a well-known structure, and a detailed illustration and description thereof will be omitted.

The heating device 200 may be a conventional electric boiler, an oil boiler, or the like.

However, it is preferable that the heat pump is composed of a heat pump connected to the underground heat exchanger 210 as shown in FIG.

Specifically, the heat pump is configured such that a plurality of underground heat exchangers 210 installed in the ground are connected to one side by piping, and the other side is connected to the heat exchanger 110 to heat the inside of the water tank.

Numerous heat pumps using geothermal heat are disclosed in Patent Registration No. 10-1199020.

An underground heat exchanger 210 for roughly absorbing heat in the ground is buried in the ground. A heat medium for moving the heat is stored in the underground heat exchanger 210 after heat exchange in the ground.

A heat pipe may be used as the geothermal heat exchanger 210, but the present invention is not limited thereto.

The submerged heat exchanger 210 is connected to the heat pump by piping. The heat pump is connected to an expansion valve, a compression stage, a condenser, a four-way valve, and the like in the same manner as a known heat pump.

The oxygen supply device 300 is configured to supply oxygen to the inside of the biofloc water tank 100, and various known aeration devices, bubble generator devices, and the like may be provided.

In the drawings, external air is supplied by a blower, but the present invention is not limited thereto.

At this time, a filter for supplying water in the water tank 100 is provided, a filter for filtering the water drawn from the filtration pump by a plurality of filter drums or the like provided therein and then supplying the filtered water to the water tank 100 is further provided, And to maintain the water quality in the water tank 100 constant.

The above-mentioned configuration is based on the use of geothermal heat as a heat source for raising the temperature inside the water tank 100 when the shrimp is cultured at a high density by implementing BFT in a region where climate change is severe or the temperature is generally low, It is possible to minimize the use of the energy source and achieve a high-density mode economically.

However, in such a bio-floc culture, it is important to supply enough oxygen in the water tank and circulate the water.

In order to achieve this, an oxygen supply device for supplying oxygen into the water tank requires a blower as shown in the drawing, and a circulation pump for circulating the water in the water tank. In this case, consumption of electric power is inevitable , Which will increase the economic burden to the users in consideration of the recent rise in the power usage fee.

Therefore, the oxygen supply device is constituted by the guide member 10 and the bubble generating means 20 which will be described later, so that sufficient oxygen is supplied to the water, and the circulation of the water is smoothly performed. It can be minimized.

Specifically, the oxygen supply device 300 includes:

A guide member 10 inclined to an acute angle with respect to a bottom surface of the water tub 100 and having a bottom section facing a bottom of the water tub 100 in a cross section and having a concave shape to form a sloped passage 11;

And bubble generating means 20 installed at a lower portion of the bottom side of the guide member 10 to generate bubbles,

And a plurality of holes (12) are formed along the longitudinal direction of the guide member (10).

3, the guide member 10 is inclined so as to have an acute angle with respect to the bottom surface of the water tub 100. The cross section of the guide member 10 has a recessed bottom surface portion facing the bottom of the water tub 100, ).

In addition, the bubble generating means 20 is provided below the bottom side of the guide member 10 to generate bubbles.

The bubble generating means 20 may be generally composed of air stones used in the water tank 100 or a known micro bubble generating device known to form a plurality of micro bubbles.

3, a plurality of holes 12 are formed along the longitudinal direction of the guide member 10 in this configuration.

4, the bubbles generated by the bubble generating means 20, such as air stones or micro bubble generating devices, tend to rise vertically due to the difference in specific gravity, The movement thereof is moved along the passage 11 of the guide member 10 by the inclined guide member 10 taking the shape.

A plurality of holes 12 are formed in the guide member 10 so that a bubble 30 larger than the hole 12 is moved along the passage 11 of the guide member 10, The small bubbles 40 pass through the holes 12 and rise.

3, when a large number of annular bubbles are installed in the water tank 100 as shown in FIG. 3, the whole of the water tank 100 ) Circulation of water occurs.

This serves to generate circulation of water in the water tub 100 without installing a separate circulation pump.

On the other hand, since the bubble passing through the hole 12 formed in the guide member 10 is small in size, the rising speed in the water is slow compared to the bubble 30 having a large velocity, The amount of dissolved oxygen in the water in the water tank 100 is increased.

The holes 12 formed in the guide member 10 separate the bubbles generated by the bubble generating means 20 in accordance with their sizes so that the small bubbles 40 are rapidly raised together with the large bubbles 30 Thereby increasing the amount of dissolved oxygen in the water in the water tank 100 as well as circulating the water in the water tank 100 by causing the small air bubbles 40 to separate from the large air bubbles 30 and slowly rising while remaining in water at a slow speed It will be a role.

The size of the holes 12 for this purpose may be differently formed depending on the size of the bubbles generated by the bubble generating means 20.

For example, in the case of a general air stone, a hole 12 of several millimeters may be formed. In the case of a device for forming a smaller bubble 40, such as a micro bubble generator, the hole 12 may be formed to be smaller can do.

In the above-described configuration, the movement direction of the small bubbles 40 separated from the large bubbles 30 through the holes 12 of the guide member 10 is guided to the circulation of water in the water tub 100 as a whole Can be utilized.

5, the bottom surface portion of the water tank 100 faces the bottom of the water tank 100 and has a concave shape. The guide member 10 The auxiliary guide 51 may be spaced apart from the upper surface of the guide member 10 to form an auxiliary passage 51 which is inclined between the upper surface of the guide member 10 and the upper surface of the guide member 10.

At this time, a plurality of auxiliary holes 52 may be formed in the auxiliary guide member 50 along the longitudinal direction of the auxiliary guide member 50, as shown in FIG.

The auxiliary holes 52 may be formed to have the same diameter as the holes 12 formed in the guide member 10 but may be formed smaller than the auxiliary holes 52 to separate the bubbles generated by the bubble generating means 20 in more detail, The amount of oxygen can be increased and the flow of water in the water tank 100 can be made more convenient.

The passage 11 in the guide member 10 is formed in a straight line so that even if the hole 12 is punctured, It may happen that the small bubbles 40 move along the passage 11. [

As shown in FIG. 6, the guide member 10 is provided on the upper portion 13 of the hole 12, and the guide member 10 is formed on the lower portion of the hole 12, And the lower portion 14 may be formed as a discontinuous surface inclined surface.

This can be applied to the shape of the auxiliary guide member 50 as shown in Fig.

This configuration is advantageous in that a small bubble 40 rising along the wall surface of the guide member 10 due to the step difference in the upper portion 13 and the lower portion 14 of the hole 12 crosses the hole 12, So that it passes through the hole 12 as it is, and is slowly lifted up to the water.

With the oxygen supply device 300 as described above, it is possible to use at least the external power with the heat pump connected to the underground heat exchanger 210, so that the bio-floc can be used sufficiently in Korea or the northern region where the seasonal climate difference is severe. High-density forms will be possible.

Particularly, the heat pump can be used as a cooling method instead of a heating method depending on the operation mode. As a result, a number of such methods are disclosed, and when the temperature of summer is excessively increased, the temperature is lowered in reverse. It can be solved.

Meanwhile, the nutrient solution cultivation apparatus 400, which is a component of the present invention, is installed on the bioflora bath 100 as shown in the figure.
