The present invention relates to an electric boiler for seawater, and more specifically, the outside of the case body is equipped with various safety devices to easily check whether the electric boiler is operating safely, and the inside of the case body is equipped with an electric boiler. A heating device consisting of multiple TCM heaters in upper and lower stages was installed to heat the water supplied through the water inlet pipe of the boiler to an appropriate temperature and discharge it through the water outlet pipe, and also directly heats the water supplied through the water inlet pipe. By supplying water heated to a set appropriate temperature through the outlet pipe so that it can be used as heating water in fish farms, etc., fish farms can maintain water for cultivating various types of fish at an appropriate water temperature, thereby promoting early growth of farmed fish species and This relates to seawater and freshwater electric boilers that help increase productivity.

In general, aquaculture is a business that fosters aquatic organisms, releasing fry in a fish farm of a certain size while storing seawater at an appropriate level, supplying nutrients necessary for the growth of the fry, and cultivating the fry until they become adults.

The operational effects according to the configuration of the preferred embodiment of the present invention configured as described above will be described as follows.

The present invention relates to a water inlet and outlet water circulation mechanism (3a) of the heating device (2) installed at the lowest side along the laminated end where a plurality of heating devices (2) are to be installed up and down inside the case body (1) of a seawater electric boiler. The water intake pipe 140 connected to one of the plurality of inlets 31 and 32 formed on both left and right sides of the case body 1 is selected from one of the plurality of water intake pipe installation portions 140a formed on the rear side of the case body 1. After inserting the pipe 140, the inserted water pipe 140 is connected to the heating device 2 installed in a stack at the bottom, and the water inlet/outlet circulation mechanism 3a of the heating device 2 installed in a stack at the top. ), the water outlet pipe 150 connected to any one of the plurality of inlet and outlet ports 31 and 32 formed on both left and right sides of the case body 1 is connected to one selected from the plurality of water outlet pipe installation parts 150a formed on the rear of the case body 1. After inserting the pipe 150, the inserted water outlet pipe 150 is connected to the heating device 2 installed at the top.

As described above, the water intake pipe 140 and the water outlet pipe 150 are connected to the plurality of heating devices 2 stacked in multiple stages inside the case body 1, and then water is supplied through the water intake pipe 140. When supplying water, first, open the manual valve 153 formed in the water outlet pipe 150 and supply water to the water intake pipe 140. The supplied water is placed in a plurality of stacked stages. It is possible to smoothly supply water to each of the heating devices (2), and when it is desired to supply water to a plurality of heating devices (2) installed in multiple stages inside the case body (1), it is installed in the water outlet pipe (150). Water must be supplied to the water intake pipe (140) with the manual valve (153) opened. This is because water is not supplied smoothly when the manual valve 153 is closed.

As described above, the operation of supplying water is performed with the manual valve 153 opened, and when the entire plurality of heating devices 2 are sufficiently filled with water, the open manual valve 153 is closed. Meanwhile, while continuing to supply water to the water intake pipe 140, when the power switch 14 formed on the front of the case body 1 is turned on, the inside of the case body 1 Each of the plurality of TCM heaters (3c) arranged left and right in each of the plurality of heating devices (2) stacked in multiple stages heats the water that is continuously supplied and circulated through the water intake pipe (14).

That is, when the power supplied from the power supply unit 200 to the main wire 210 is applied to each of the straight main terminal (5a) and the straight auxiliary terminal (5b), the straight main terminal (5a) and the straight auxiliary terminal (5b) are connected to each other. Power is applied to both ends of the transparent conductive layer 320 of the TCM heater 3c to which the main connection terminal 51 and the auxiliary connection terminal 52 formed in are connected, thereby causing the TCM heater 3c. The transparent conductive layer 320 generates heat and heats the transparent glass tube 310, thereby heating the water circulating in the transparent glass tube 310 of the TCM heater 3c. This water heating operation is performed by heating the water. Since the circulation continues through the plurality of TCM heaters (3c) in a zigzag fashion, the plurality of TCM heaters (3c) arranged in the first stage (F ₁ ) heating device (2) stacked at the bottom are circulated in a zigzag fashion. The water begins to be heated and circulates through a plurality of TCM heaters (3c) arranged in each stage from the second stage (F ₂ ) heating device (2) to the top 9 stage (F ₉ ) heating device (2). During the continuous heating operation, the water passing through the plurality of TCM heaters (3) arranged in the 9-stage ( _F9 ) heating device (2) is discharged to the water outlet pipe (150) in a state of being heated to a set high temperature. , Accordingly, the water discharged through the water outlet pipe 150 is discharged in a state heated to a set high temperature.

Therefore, by receiving water heated to a set high temperature as heating water, aquaculture companies can not only heat the seawater stored in the fish farm to a temperature most suitable for the fish species, but also maintain a constant temperature of the sea water stored in the fish farm. Since it can be maintained, it not only helps a lot in the growth of farmed fish species, but also has the advantage of increasing the productivity of farmed fish species.

Meanwhile, the seawater electric boiler of the preferred embodiment of the present invention includes a plurality of TCM heaters (3c) and a plurality of U arranged in a plurality of heating devices (2) stacked in multiple stages inside the case body (1) as described above. When an air layer (bubbles) is formed in the water circulating in the shaped connector 6, a phenomenon may occur where the water does not circulate smoothly, but in this case, the 8th stage (F ₈ ) and 9th stage (F ₉ ) The air layer present in the plurality of TCM heaters (3c) is removed by opening the water discharge control valve (63) installed on the U-shaped connector (6a) connecting the heating device (2) to discharge water. After removing the air layer, by closing the water discharge control valve 63, the water supplied to the plurality of heating devices 2 installed in multiple stages can be smoothly circulated.

Therefore, in the present invention, the water supplied to the plurality of heating devices (2) stacked in multiple stages inside the case body (1) of the preferred embodiment is provided by a plurality of TCM heaters arranged left and right in each of the plurality of heating devices (2). As (3c) is circulated in sequence, it continues to be gradually heated to a higher temperature, so the water discharged through the water outlet pipe (150) after circulating through the plurality of TCM heaters (3c) arranged in the uppermost heating device (2) is It can be heated to a set appropriate temperature and supplied as heating water to fish farms.

In addition, the present invention can supply high-temperature heated heating water set to heat sea water (or fresh water or deep water) stored in the fish farms of aquaculture companies operating aquaculture as described above, as well as for use by people in bathhouses, saunas, etc. It can also be used as an electric boiler to heat and supply bathing water to a set appropriate temperature.
