Description

Aquaculture Feeder

The present invention relates to a breeding water supply device for aquaculture, and more particularly, to a breeding water supply apparatus for supplying to a farm breeding tank by constantly processing the temperature of the introduced raw water.

In general, mothers and larvae of fish and shellfish are subject to a lot of stress due to rapid changes in water temperature, so maintaining proper water temperature is very important and must be farmed under sophisticated environmental conditions.

These larvae (larvae, scallop and shellfish larvae, flounders, and fry) grow up to eat plankton underwater and are extremely sensitive to breeding temperatures.

Breeding water temperature in winter usually decreases to about 4 ℃ and in summer, it can rise to about 28 ℃. However, each living animal must maintain its proper temperature.

If these temperatures are not maintained and fed into a breeding tank or laboratory test farm, the mother and larvae of the target organism will face a fatal situation.

Therefore, in order to always feed the breeding water at the appropriate temperature regardless of the change of the season, the warming means for heating the incoming raw water by an appropriate method and the cooling means for cooling the conversely are required.

Conventionally, aquaculture breeding water supply apparatus for supplying breeding water to aquaculture farm breeding tank at a constant temperature uses a common boiler, a cooling system, and a pipe line having a predetermined structure connecting them to heat or cool the raw water to breed the farm. The breeding water is supplied at a constant temperature.

However, the conventional aquaculture breeding water supply apparatus described above has the following problems.

1. A boiler (heat exchanger) or a cooling device as a part of the supply device is repeatedly started / stopped according to a preset temperature of a temperature sensor, which is due to a temperature difference of approximately ± 2 ° C or higher. The frequent repetition of start / stop causes the device to easily fail.

2. The above conventional apparatus has a wide range of temperature deviations for setting the reference temperature for commanding start / stop, and thus it is difficult to precisely control the constant temperature state of breeding water due to difficulty in precise control.

3. In addition, the conventional apparatus has an inefficient operation due to excessive oil consumption and power loss, and in severe cases, leads to an explosion of the apparatus, causing a safety accident of an operator.

The present invention has been invented to solve the problems appearing in the conventional apparatus, the purpose is to provide a high-quality aquaculture breeding water that can always supply the raw water of the appropriate temperature to the farm breeding tank or laboratory breeding tank regardless of the season In providing a supply device.

When the ultraviolet sterilizer is installed in the inlet pipe line, the sterilization of the breeding water can be achieved by directly sterilizing and supplying harmful bacteria contained in the raw water.

Hereinafter, with reference to the accompanying drawings Figure 1 will be described in more detail with respect to the automatic feeding device for breeding fish of the present invention.

1 is a schematic view showing a configuration showing the present invention. Although FIG. 1 is substantially one figure, it is divided into two for understanding, and the right line of FIG. 1A and the left line of FIG. 1A show a connected state.

First, the system shown in FIG. 1A will be described. In this figure, reference numeral 10 denotes a heat exchanger. The heat exchanger 10 exchanges heat between the hot water circulated by the ordinary boiler 20 and the raw water in the raw water tank 30.

At least two circulation pumps 12 and 22 are provided for circulating hot water from the heat exchanger 10 and the boiler 20, and at least two circulations for heat exchange in the raw water tank 30 are also provided. Pumps 32 and 34 are provided.

Of course, these circulation pumps 12, 22, 32, and 34 are connected along a predetermined pipe line.

Reference numeral 12 is a boiler hot water circulation pipe, 24 is an oil tank for supplying raw materials to the boiler 20, 26 is a boiler water supply means, 33 is a raw water circulation pipe.

In the raw water tank 30, a discharge pipe 35 connected to the circulation pumps 32 and 34 is disposed near the bottom, and heat exchanges through a plurality of large and small holes formed in the discharge pipe 35. To detonate warmed or cold enemies.

And the upper end of the raw water tank 30 is provided with a temperature sensor 36 as a temperature sensing means for detecting the raw water temperature in the raw water tank 30, the inlet pipe for receiving raw water (sea water) from the outside ( 37) is installed.

Two pipes shown on the right side of FIG. 1A or the left side of FIG. 1B are a drainage side pipe A and a water intake side pipe B. As shown in FIG. First, the structure provided along the drain side piping A line is demonstrated. At least two pumps 52 and 54 are provided in the drain side pipe A in order to allow raw water to flow to a heater or a cooling device described later. At least two heaters 62, 64 as heating means are provided at the downstream end of the pump to heat the raw water, and at the end, several coolers 72, 74, 76, etc. as cooling means. Is installed.

On the other hand, the inlet-side pipe (B) is provided with an ultraviolet sterilizer 80, the discharge pipe 90 for discharging the raw water, which is finally heated or cooled and sterilized to the farm breeding tank.

This sterilizer 80 adopts the " ultraviolet-flow flowing sterilizer " disclosed in the applicant's registered patent application No. 122027 (September 2, 1997; notification number 97-9643). This is achieved by properly arranging the UV lamp and the pipe. The seawater passing through the channel is directly irradiated with UV rays emitted from the UV lamp to sterilize harmful bacteria contained in the raw water.

In FIG. 1B, the drain side pipe (A) or the inlet side pipe (B) includes a plurality of drain valves 102, 104, 106 for use in temporarily draining water from the pipe for cleaning or inspection purposes. ), 108, and 110 are connected.

Since the configuration of other control panel or accessory control device of automatic panel is general, it will be omitted below.

The operation of the breeding water supply apparatus for aquaculture of the present invention having such a configuration will be described.

First, it is assumed that the raw water flowing into the raw water tank 30 is 10 ° C, and the proper temperature of the breeding water to be supplied to the farm breeding tank to be most suitable for aquaculture is 20 ° C.

In the boiler 20, about 8 ° C is further heated to raise water such that water of about 18 ° C is lower than a predetermined temperature, for example, 2 ° C below the proper temperature. Therefore, in the boiler 20, the circulating water is heated and sent to the heat exchanger 10 using the circulating pumps 12 and 22. At this time, since heat is taken away by heat exchange, the circulation water must be supplied at a temperature higher than the set temperature of 18 ° C.

In the heat exchanger 10, the circulation pumps 12, 22, 32, and 34 are installed at both sides to perform heat exchange between the boiler circulating water and the raw water.

Here, the heated hot water (circulating water) is brought up to 18 ℃ the water of 10 ℃ raw water.

On the other hand, since the boiler circulating water replenishment pipe is installed on the boiler side to supply the water insufficient to the boiler, hot water insufficient due to evaporation is always supplied.

Cold raw water is also supplied to the heat exchanger 10 through the raw water circulation pipe 33 and heat-exchanged to a temperature close to 18 ° C, and then to the raw water tank 30 through the jet pipe 35. In the form of aeration inside.

The reason why the two pumps 12, 22, 32, and 34 are installed in pairs is that pumps cannot be operated continuously so that they can be operated alternately every 1-2 hours. This is to increase the durability by protecting the pump parts including the motor.

Subsequently, the first heated raw water flows into the drain pipe A by the pumps 52 and 54 installed in the drain pipe A in the two pipes shown on the left side in FIG. 1B (see arrow). . Since the primary heated raw water flowing along the drain side pipe A line is provided with two heaters 62 and 64 as heating means for warming the raw water secondly, the heaters 62 and 64 are heated. At 2 ° C, seawater, which is about 2 ℃ lower than the optimum temperature, is heated at a temperature of 20 ℃.

By the way, in the heaters 62 and 64, when the raw water temperature is higher than the proper temperature due to overheating, the coolers 72, 74 and 76 provided at the end of the drain side pipe A are removed. To cool.

Of course, the coolers 72, 74, and 76 are used for cooling when the raw water temperature is higher than the proper temperature in the summer, but fundamentally precise control of raw water, which is difficult to control even with primary and secondary heating. It is also used to do.

The raw water at the proper temperature passing through the coolers 72, 74, 76 is returned toward the raw water tank 30 in the direction of the arrow. At this time, since the ultraviolet line sterilizer 80 is installed in the middle line, that is, the water inlet pipe B, the harmful germs active in the raw water are sterilized and finally discharged to the breeding tank through the discharge pipe 90. .

For better understanding of the description, the direction of the raw water flowing in the drainage side pipe A (the direction exiting from the raw water tank 30) is indicated by the arrow with the arrowhead being blank, and the raw water flowing in the inlet side pipe B. The direction of [the direction entering the raw water tank 30] is indicated by the arrowhead filled arrow.

The amount of processed raw water going to the final discharge pipe 90 is about 1/10. As a result, the amount returned to the raw water tank 30 is 90%.

As such, the present invention eliminates waste of power and excessive oil caused by instantaneous heating of raw water and sterilizes bacteria contained in the raw water so as to always supply proper breeding water to the breeding tanks. It is equipped with a cooler that raises the temperature as much as possible by heat exchange with the incoming raw water, adjusts it to the proper temperature precisely by using a pair of heaters, and finally cools the irregularly heated raw water.

As described above, according to the breeding water supply apparatus for aquaculture of the present invention, the breeding water of the proper temperature controlled by precisely controlling the primary warming through the heat exchange method in the heat exchanger, the secondary warming in the heater, and finally cooling in the cooler is supplied. In addition, since a means for sterilizing the bacteria contained in the raw water is provided, highly desirable breeding water can be supplied to the aquaculture farm breeding tank.
