Description

[0001]
[Industrial application fields]
The present invention is a cold seawater sterilization system in which the sterilized seawater to be used as treated water when shipping seafood to the market etc. is continuously sterilized not only at the time of supplying water from the raw seawater filtration device but also in the water storage tank. It relates to the device.
[0002]
[Prior art]
Conventionally, as this type of cold seawater sterilizer, as shown in FIG. 4, the seawater poured into the water storage tank (30) through the filtered water injection pipe (34) is supplied from the lower filtered water outflow pipe (36). The circulating water (31) is cooled by the cooling unit (32), sent from the cooling unit (32) through the cooling water pipe (37) to the sterilizer (33), and sterilized seawater is cooled and sterilized outflow pipe ( It is known that it is injected into the water storage tank (30) via 38) and then supplied to various water tanks and the like by a water pump (35).
[0003]
[Problems to be solved by the invention]
In the prior art, since a sterilizer is interposed between the cooling unit and the water tank, there is an economical problem that requires complicated piping loss and installation location, and When the sterilizer installed outside is out of order, there is a serious problem that the water tank is stopped and the circulation of seawater is stopped.
The present invention has been made in view of the above problems, it is an object of replacement, such as a lamp, the sterilizing unit, even in the case of repairs, etc., is plug in sterilization provided in the water tank Therefore, an object of the present invention is to provide a cold seawater sterilizer capable of continuously using sterilization without stopping the circulation operation.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, according to the cold seawater sterilization apparatus of the present invention, a water storage tank having a sterilization chamber at a predetermined location is provided inside the water storage main body. The sterilization chamber has an ultraviolet lamp and quartz inside. A sterilization unit having a tube is installed vertically. In addition, air from an air pump is injected into the space of the ultraviolet lamp and the quartz tube through the air tube, and an air disperser connected to the air pump is provided in the water storage tank. Furthermore, the circulation is repeated in the sterilization chamber through a circulation pump and a cooling unit from a circulation and delivery section provided in the water storage tank. Furthermore, water is poured into a fish tank through a water pipe by driving a water pump located below the water tank.

【Example】
Referring to the drawings, an embodiment of the present invention will be described. A water storage body (1), a circulation pump (2), and a cooling unit (3) are linked to each other, and the water storage body (1) includes a water tank. (6) and a partition are provided, and a sterilization chamber (5) is formed in an internal corner or the like. In the sterilization chamber (5), a sterilization section (7) composed of an ultraviolet lamp (8) and a quartz tube (9) communicating with the lighting device (11) is provided vertically. Into the sterilization part (7), air from the air pipe (13) from the air pump (10) provided outside is injected into the space inside (A), and the air pipe (13) from the space inside (A). Is communicated with the air disperser (21) provided near the bottom of the water tank (6). Next, in the sterilization chamber (5), a raw water inlet (14) that enters from a filtrate water injection pipe (29) from a filtration device is installed in the lower part, and the raw water inlet (14) is installed side by side from a circulating water pipe (23). Circulating water inlet (12) is installed. The circulating water pipe (23) is connected to a circulation delivery part (22) provided at the lower part of the water storage tank (6).
[0006]
Next, a water supply pipe (24) that operates by driving a water supply pump (25) is communicated with the water tank (6). The water supply pipe (24) is provided with several water supply valves (26) via a water supply pump (25) to inject water into various fish tanks (27) and (27). Reference numeral (28) denotes a discharge portion for discharging the air provided in the upper portion to the outside.
Further, the water tank (6) is provided with a level switch (15) at a predetermined position in the upper part. The level switch (15) is equipped with a water intake pump (16), a water level lower limit alarm (17), a water level lower limit alarm (18), an OFF circulation pump (2), and a sterilizer (7). On the other hand, a water level upper limit alarm (19) and an OFF water supply pump (20) are installed at the bottom.
[0007]
[Action]
The present invention has the above-described configuration, and what is shown in FIG. 1 shows the overall configuration of the sterilization apparatus showing the periphery of the water storage main body (1), and is filtered from a filtration apparatus (not shown). Seawater and the like entered the sterilization chamber (5) from the filtered water injection pipe (29) and are sterilized. Seawater that overflows due to the rise of the water level in the sterilization chamber (5) enters the water storage tank (6), and the water sterilized by the air disperser (21) installed inside makes the seawater agitation and water temperature constant. . Operation of the level switch (15) installed in the interior ensures the safety of the intake and water pumps by turning them off and on, and the water level upper and lower limit abnormalities, alarms and other OFF and ON operations. Yes. Next, the sterilization inside the water tank (6) and the seawater replenished with air are circulated through the circulating water pipe (23) via the circulation pump (2) from the circulation delivery part (22), and the cooling unit (3 ) Through the circulating water pipe (23) and sent from the circulating water inlet (12) to the sterilization chamber (5).
Next, sterilization and cooled seawater etc. inside the water tank (6) are operated from the water pipe (24) located below the water tank (6) by operating the water pump (25) and the water supply valve (26). It is automatically operated by opening and closing (26) and is supplied to various water tanks (27).
[0008]
【The invention's effect】
The present invention is configured as described above, and compared to a conventional sterilizer installed outside, there is no need for piping equipment, no installation place, and no heat loss of cooling. It has an excellent economic effect. Since the water storage tank and the sterilization chamber are integrally formed in the water storage body via the partition wall , the entire system is remarkably reduced in size, and in the case of a failure of a lamp or the like, the sterilization unit is installed in the sterilization chamber in the water storage tank. Has an excellent effect that the lamp can be replaced without stopping the circulation of the seawater. In addition, since sterilization is continued not only when water is supplied from the filtration device but also after storage, safety can be significantly improved, and the water in the water tank is agitated with sterilized air to keep the water temperature uniform. There is an effect that can be done. Moreover, even when the water level is lowered by using seawater, the sterilization of the internal water tank is filled with air, so that there is a sanitary effect that the outside air does not enter. Furthermore, there is also an effect that water can be poured into a fish tank located far away by a water pipe that is operated by driving a water pump .
