Description

{Aquaculture tank for bio-flock}

The present invention relates to a biofilm energy aquaculture tank. More specifically, a partition wall is provided at the center of a water tank body, a horizontal bar movable along a partition wall, a guide rail formed on left and right sides of the water tank, and a DO sensor connected to a lower portion of the horizontal bar The present invention relates to a bioflavonaceous aquaculture tank for biofuel, in which oxygen is injected into a venturi provided inside a water tank and the dissolved oxygen amount of the breeding water is automatically controlled when the number of breeding water is less than a set dissolved oxygen amount while performing reciprocating linear motion.

Biofloc technology is a technology that uses heterotrophic bacterium and aquaculture to cultivate together heterotrophic bacterium to decompose organic byproducts in the aquarium water 10 to 100 times faster than algae to purify the water, The organic byproducts decomposed in the broodstock are fed to the cultured fish species, so that the filtration process such as water exchange and water treatment is not necessary.

A major feature of the technology is that microorganisms such as lactobacilus, photosynthetic bacteria, and yeast, which are commonly used in fermented foods, are used in the biofloat-based aquaculture method. The mechanism is to add carbohydrates (starch, cellulose) to the water of the tank with increased nitrate amount, and when the amount of carbon in the water increases, the microorganism produces protein with nitrogen as the nutrient, Principle.

Biofloat-based aquaculture does not discharge the water from the farm, but maintains the water quality by utilizing the natural water purification function of environment-friendly microorganisms while using it continuously. In addition, since natural proteins and amino acids produced by microorganisms can be used as food, it is possible to prevent the inflow of diseases such as natural immunity (non-antibiotics) and viruses at the origin (non-pathogenic) , It is 20 ~ 50 times more effective than conventional farms due to the rapid growth rate of breeding creatures.

In a conventional aquaculture tank using a biofloat, a water tank body is formed with a bottom portion having a predetermined area surrounded by an outer wall of the water tank, and a water temperature adjusting device and a blower device are installed inside the water tank. The role of devices such as air blowers or circulation pumps is particularly important in biofloat-style applications. This is because organic matter and microorganisms distributed in the breeding water may clump together and sink to the bottom of the water tank if a constant stream of water is not formed.

It is difficult to expect smooth action because the sinking organics and microbial mass are distributed only in the bottom of the water tank, and functions such as feeding water purification and feeding of aquaculture fish are only partially performed on the bottom of the tank. Therefore, it is necessary to provide a water stirring apparatus such as a circulation pump to form a water stream in a certain direction, and to continuously disperse organic matter and microorganisms.

However, since the circulation pump for generating the water flow must operate 24 hours during the cultivation, the amount of energy consumed to operate the circulation pump accounts for about 40-50% of the total farming energy supply, It will be a burden. Therefore, it is possible to produce environmentally friendly and efficient energy, reduce the amount of circulating pump energy, which accounts for half of energy consumption, and develop a water tank and system.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to specific configurations and accompanying drawings relating to a bioflavonetic energy storage tank.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a perspective view of a biofloating aquaculture tank of the present invention. The bioflavonery culture tank for biofabric according to the present invention comprises a water tank main body 10 having a bottom and a water tank outer wall with an open top and a predetermined area and a partition 11 formed at the center of the water tank main body, A horizontal bar 21 and a DO sensor 40 are provided so as to be movable along the guide rails 20 formed on the water tank main body and the partition wall, The venturi 30 may be installed in the venturi.

The guide rails 20 may be formed on the left and right upper surfaces of the water tanks, and on the upper side of the partition walls. The partition 11 is formed in the same shape as a wall having a width and a length shorter than that of the water tank and is formed at the same height as the outer wall of the water tank and no barrier ribs are formed on the front and rear portions of the water tank, .

The horizontal bar 21 may be installed on the guide rails 20 formed on the side walls of the partition wall and the outer wall of the water tank. The horizontal bars are provided on the left guide rail and the upper surface of the partition, on the upper surface of the partition and the right guide rail, respectively, and perform reciprocating linear motion along the guide rail in the front and rear direction of the water tank. In the reciprocating linear motion, a contact switch (not shown) is formed at both ends of the guide rail. When the horizontal bar contacts the contact switch of either one of the contact rails, the power or gear of the motor driving the horizontal bar is rotated, .

A DO sensor 40 is connected to the bottom of the horizontal bar toward the bottom of the water tank, and generally comprises a sensor head and a sensor body. The sensor body is connected to the horizontal bar, and the sensor head is installed at the lowermost part of the sensor body. The DO sensor detects the amount of oxygen dissolved in the water in the tank, and when the horizontal bar is operated, the DO sensor moves together with the DO sensor, .

Fig. 2 shows a top view of an energy-free style water tank for biofabric of the present invention. The venturi 30 can be installed on the left and right inner side surfaces of the water tank main body and the left and right sides of the water tank bulkhead, and the spray angle can be adjusted within the range of 0-180 degrees. Venturi injects oxygen and stirs microorganisms or organic matter into the bottom of the water tank so that it does not sink, or increases dissolved oxygen in the water tank.

As shown in FIG. 2, as an embodiment of the present invention, by injecting oxygen into the venturi at a certain angle and direction, the number of animals in the water tank has a rotational force in a certain direction. The breeding water can be prevented from accumulating on the floor sediments such as microorganisms and organic matter distributed in the breeding water during biofloat culture while being stirred in the water tank. In the case of biofloat, if organic matter and sediment accumulate on the floor, it will be rotten. In the present invention, the pump for supplying the oxygen or the breeding water to the venturi for stirring is installed on the four corners of each of the front and rear sides in the case of the rectangular water tank, and the motor is operated for 5 minutes with the inverter function, Perform a resting repeated drive. This is because the time taken for the microbial masses to disperse in the water is not taken into consideration while the water is stirred by the venturi. Therefore, in the conventional breeding tanks, motors are continuously driven for 24 hours. However, in the present invention, since the microorganisms in the breeding water are stirred and not driven, the energy saving effect is obtained. Normally, the amount of energy consumed by the pump is 40-50%, the heating facility is 40-50%, and the oxygen supply device such as a blower is 10% in order to operate the aquaculture tank. In the present invention, the energy used in the pump can be reduced through the operation of the inverter as described above.

The venturi is made up of a bubble generator and can inject nano bubbles. The nano bubble is a micro-bubble with a diameter of several hundreds of micrometers or less. The bubble, which is ordinary air bubbles, rises at high speed in water and ruptures on the surface. .

The bubbles of nano-bubbles are so small that the volume of buoyancy is low and buoyancy is slowly increased to the surface while many nano bubbles are reduced by pressure in the water before reaching the surface of the water. And the time for oxygen to dissolve in water is increased, so that the amount of dissolved oxygen in the water can be increased. In addition, Venturi has the effect of saving the energy by the optimum control method through application of the inverter function, and also it is possible to control by the set value set by the user. Since the blower for supplying oxygen is not used separately, it is possible to reduce the energy input to the blower.

The venturi and the DO sensor operate according to the concentration of DO contained in the water tank by applying the internet of things (IOT) technology. The Internet of Things (IOT) refers to the object space network that forms intelligent relationships such as sensing, networking, and information processing in a cooperative manner without human intervention for the three distributed environmental factors of human being, objects and services.

Objects that are components of the Internet include not only end-devices in wired / wireless networks, but also human, vehicles, bridges, various electronic equipment, cultural properties, physical objects constituting the natural environment, and the like. .

The Internet of things can be made up of three main technologies: sensing technology, wired / wireless communication and infrastructure technology, and IOT service interface technology. Sensing technology includes physical sensors that can obtain information from type objects and surrounding environment such as remote sensing SAR, radar, position, motion, image sensor, etc. from temperature, humidity, heat, gas, illumination and ultrasonic sensors. The IOT service interface technology is a technology that interlocks the objects, objects, and services of the Internet of objects with application services that perform specific functions, and can operate the sensing technology through wired / wireless communication and network infrastructure technology.

The agitation of the bioflavonic energy storage tank of the present invention is performed by measuring the dissolved oxygen concentration of the breeding water in real time while the DO sensor is moved in the water tank body and comparing the measured dissolved oxygen concentration with the predetermined reference range by the user, And increases the amount of dissolved oxygen by generating oxygen stream or feed water. More specifically, the DO sensor is generally installed in one part of a general farm, and the DO sensor is fixedly installed at a certain place in a conventional farm, so that only a limited range of the dissolved oxygen amount is measured The overall management of oxygen deficiency in breeding water was difficult.

In the present invention, when the DO sensor continuously moves before and after the water tank, the dissolved oxygen amount of the water is detected, and when the dissolved oxygen amount is detected below the reference value, the venturi operates to form water flow in a certain direction together with the nano- Increase the amount of dissolved oxygen. When the DO sensor senses that the amount of dissolved oxygen in the water tank has increased above the reference value, the operation of the venturi is inhibited and the agitation is performed only when necessary compared to the conventional farm where the venturi is continuously injected. Generally, the ventilator is operated when the DO value of the breeding water is less than 4ppm based on the minimum dissolved oxygen amount (4 - 6ppm) that the fish can survive when aquaculture is cultured.

FIG. 3 is a perspective view of a solar panel of a zero-form water tank for a bioflare of the present invention. One or more solar panels (50) are installed on the upper side of the horizontal bars to use solar energy, thus enabling an eco-friendly energy zero forming system to produce and consume energy in an environmentally friendly manner without receiving power from the outside.

A panel is installed on the upper side of the panel to receive solar energy and can be converted into electric energy. On the lower side of the panel, a plurality of wires capable of moving the converted electric energy can be installed. The solar panel of the present invention may be composed of a supporting frame connected to the upper surface of the horizontal bar and a panel absorbing solar energy. The supporting frame is formed with a square frame structure so that the corner is connected to the edge of the panel by a hinge so that the angle can be adjusted from 0 to 90 degrees with the ground, and the angle can be fixed by the supporting frame.

In the embodiment of the support structure of the present invention, the supporting frame is a rod frame, a thread is formed on the outer side surface, a thread is formed on the inner side surface of the through hole formed in the up and down direction of the supporting frame, So that they can be adjusted and fixed.

Fig. 4 shows a solar panel mounting principle of an energy-free style water tank for a bioplacer of the present invention. In the method of mounting the solar panel of the present invention on a horizontal bar, grooves are formed on the upper surface of the horizontal bar and protrusions 60 are formed on the lower surface of the support frame so as to slide the protrusions on the upper surface grooves of the horizontal bar, Respectively.

5 shows the principle of operation of the horizontal bar of the energy-free style water tank for biofabric of the present invention. Photovoltaic panels absorb solar energy and convert it into electrical energy, which then supplies the energy to drive inverters or DO sensors, horizontal bars, and heating systems. The energy source can be replaced with an environmentally friendly energy source such as solar energy using solar panels, waste heat recovery from power plants, and renewable energy other than solar energy.

The horizontal bar supplied with the electric energy is linearly reciprocated in the front and back directions of the water tank body at a constant speed, and the DO sensor can sense the entire water tank in real time. Due to the nature of biofloat, the amount of dissolved oxygen differs in different parts of a large-sized water tank, so that the amount of dissolved oxygen differs depending on the location in the same tank. Therefore, when the DO sensor is fixed in one part, I can not kill aquatic creatures. However, as described above, since the DO sensor continuously and linearly moves forward and backward in the water tank, it is possible to detect the dissolved oxygen amount of the entire water tank, so that it can be applied to the bioflag water tank on a large scale.

The DO sensor injects oxygen in the venturi when oxygen content is reduced to less than 4-6 ppm, and oxygen or water is generated as the water for breeding and agitates the microorganism or organic matter on the bottom of the water tank It is possible to prevent stagnation.

In addition, when the sensor exceeds 4 ppm, the oxygen injection of the venturi is stopped and the oxygen injection is performed only when necessary. Therefore, not only the energy of the circulating pump which occupies the largest consumption amount in the biofrost style can be reduced, This new renewable energy makes it possible to install zero-energy farms that can produce and consume energy in farms without external power.

By using bioflavonable aquaculture systems capable of energy zero systems, oxygen firing is partially activated only when the dissolved oxygen content of the breeding water is outside the range of viable fish species, By using renewable energy as an energy source, it is possible to reduce the expense for maintaining eco-friendly farming and farming system, and thus it can be used industrially because it can contribute to increase income of fishermen by raising international competitiveness of aquaculture technology.
