Description

Cold water supply machine for live fish tanks

The present invention relates to an apparatus for maintaining fish caught in a fishing vessel in a live fish state, and more specifically, cooling water supply to a live fish tank by cooling the water to a temperature at which the fish in the fish tank is activated to supply the cold water for a live fish tank Relates to a device.

In order to maintain the freshness of the captured fish, the captured fish were initially transported to the land with a mixture of seawater and ice at a ratio of 5: 5 when placed in the fishery. However, this method is to load the fish at the same time by mixing the seawater and ice, that is, the land ice, so it is the same as loading the fish in the seawater and freshwater mixed water. There is a problem falling. Therefore, in the case of the operation up to the ocean, most of the fish dies or loses freshness in the process of transporting the captured fish to the land, there is a problem that can not be paid. Dead fish can only be used as feed, which is a huge loss for fishermen. This problem is more severe in the summer, the high temperature in the summer, the captured fish will die faster or worse. Therefore, in the summer, it is not profitable and abandons its operation, and thus, even related industries (sashimi, fish market, etc.) are stagnant.

In addition, when the sea water is supplied in summer, because the temperature of the sea surface is high, the sea water of more than 70m depth is pumped and supplied. The temperature of seawater, which is 70m deep in the sea, is about 12 ℃, and the fish are most active at this temperature. However, such a method has to lengthen the hose for deep pumping deep in the sea, there is a problem that always load the pump.

In order to solve the above problems, a method and a device (hereinafter referred to as a prior art) for transporting captured fish for a long time without losing freshness while being transported to land have been developed (Application No. 10-1998-030114). The prior art is equipped with a fish tank that can hold the catch in the vessel and a cooling device that can cool the sea water to -1 ℃ temperature, go to the fishing ground and fill the fish tank with about 2/3 of the sea water of -1 ℃ temperature and then live Fresh fish by seawater cooling which puts catches in fish tanks and immediately kills them with cooling seawater at -1 ℃ and circulates the seawater in the fishery to the cooling device to keep the seawater temperature at -1 ℃ for a long time. Iii) transportation method and apparatus.

Referring to FIG. 1, the chiller 10 is connected to the condenser 11 and the compression pumps 12 and 12 ′ forming a cooling device, and the chiller 10 is operated by a plurality of fish tanks No 1 to No 5. It is configured to supply the cooling sea water through the cooling sea water supply pipe (40). The chiller 10 cools the seawater pumped from the motor pump 20 and supplies the chilled water to the fish tanks No1 to No5. On the other hand, the fish tank (No1 ~ No5) is connected to the sea water absorption pipe 30 and the cooling sea water supply pipe 40 through the valve (V1, V2), respectively, some of the plurality of fish tank (No1 ~ No5) It is configured to be used. Although not shown in FIG. 1, a seawater temperature sensor is installed in each of the fish tanks No1 to No5 to control the opening, starting, and stopping of the valves V1 and V2 and the motor. The seawater temperature in the vessel is maintained at -1 ° C.

Reference numeral 50 is a main valve installed on the sea water absorption pipe 30, 60, 61 is a sea water distribution pipe for cooling the cooling device.

2 and 3, the main body 10a of the chiller 10 has a cylindrical shape with both ends blocked, and a plurality of seawater distribution pipes 10b are installed in the longitudinal direction thereof, and hemispherical bodies 10c and 10c 'are provided at both ends. ) Is fixedly installed, an intermediate partition 10a is formed inside the hemispherical body 10c, and a sea inlet 10e and a seawater outlet 10f are formed outside. In addition, the upper and lower portions of the main body 10a are formed with an inlet 13 and an outlet 13 'of the coolant so that the coolant can cool the seawater distribution pipe 10b.

4 and 5, the upper portion of the cylindrical portion 70 constituting the fishing window, the bent portion 71 formed to be large enough to pick up the catch with a mechanical large tongs, and the lower portion of the inner wall of the portion 71 An inwardly facing jaw 72 is formed, and a plurality of inner lids 73 and 73 'are covered with a size that can be artificially opened and closed to the inwardly facing jaw 72, and also an inner lid 73 and 73'. The presser rods 74 and 74 'are pressed against the inner lid and bolted to both sides with screws 75 and 75'. A plurality of outer lids 76 and 76 'are covered at the upper end of the bent 71, and cooling sea water import and inlet 77 and outlet 78 are installed at both sides of the upper end of the cylinder 70 outside the bent. The water outlet 78 extends to the bottom of the net board 79 provided at the lower end of the fishing window, and is configured so that the catch is not sucked out when seawater is extracted.

Referring to the operation of the prior art fishing vessel configured as described above are as follows.

To operate in a state where the valves V1 and V2 installed in the plurality of fish tanks are all closed, first open the main valve 50 and open the valve V1 of the fish tank to be used, and then operate the cooling device to operate the refrigerant in the chiller 10. When the water is cooled, when the motor pump 20 is turned to pass seawater through the chiller 10, the seawater is cooled to a temperature of −1 ° C. and is obtained into the fish tank through the fish tank valve V1. At this time, when the operator confirms the amount of seawater sufficient for the naked eye (about 2/3), the main valve 50 is closed, and the valve V2 is opened and the fish is ready to put the catch in the fish tank. Then, when the catch is placed in the fish tank, the fish in the live state is killed at -1 ℃ cooling seawater and the temperature of the seawater rises. At this time, the electric device operates the cooling device and the motor pump 20 by the signal of the seawater temperature sensor. By circulating the seawater in the fishery in the chiller (10) to maintain the seawater temperature -1 ℃ continuously.

During the operation, there is a net board 79 at the bottom of the fish tank and the recovered sea water is sucked up under the net board 79 so that the catch is not sucked out, and the seawater distribution pipe 10 b in the chiller 10 is in the longitudinal direction of the inside. Since the hemispherical bodies 10c and 10c 'are fixed to both ends, the seawater distribution hole is not blocked even when the scales of the catch are sucked in the circulating seawater.

As described above, the prior art fish conveying method and conveying apparatus by seawater cooling immediately kill fish caught in seawater of -1 ° C, and store and transport the raw fish in the incubator holding the temperature of -1 ° C as it is. To maintain freshness. Since the above method does not use the land ice at all, it has the effect of reducing the oil cost, reducing the crew, and reducing the land ice purchase cost.

However, the above-mentioned prior art sea ice conveying method and apparatus have a problem in that enormous amounts of energy are required to cool the seawater to -1 ° C. Sea water does not freeze well below freezing because of its base, and cooling is also difficult. Therefore, cooling the seawater to -1 ° C requires a lot of energy, and in the case of small vessels other than large vessels, the prior art fishing vessels are not practical. In other words, there is a problem that not only the device cost but also the operation and management cost becomes expensive, so it is difficult to use in a small ship.

Therefore, in order to solve the above problems, the present invention maintains the fish in a live fish state without freezing, which enables long-term storage and transport, and provides a cold water supply device for live fish tanks that can be used in various ways in small vessels or on land due to low equipment costs and operation management costs.

In order to achieve the above object, a live fish tank for cold water supply according to the present invention includes a water tank configured to receive water; A pump for circulating water forcibly passing the live fish tank through the tank; A coolant supply device formed outside the water tank and supplying a coolant for cooling water introduced into the water tank by the pump to a predetermined temperature at which the fish is activated; A plurality of refrigerant flow pipes installed in the tank to provide a flow path of the refrigerant supplied by the refrigerant supply device; The water pumped into the tank is characterized in that it comprises a diaphragm installed to be discharged out of the tank after a long stay in the tank.

In addition, the refrigerant flow pipe, and the copper pipe for providing a flow path of the refrigerant; Wrapping the copper tube is characterized in that it comprises a stainless tube to prevent the copper tube is corroded by the base of the sea water.

Hereinafter, with reference to the accompanying drawings will be described in detail the configuration of the live fish cold water supply apparatus according to the present invention. Figure 6 is a state diagram used in the live fish cold water supply apparatus according to an embodiment of the present invention, Figure 7 is a perspective view of a portion of the tank portion of the live fish cold water supply apparatus of Figure 6 cut. 8 is a plan view of FIG.

Referring to FIG. 6, the cold water supply device for live fish tanks sucks water from the live fish tank 110 using the pump 111, cools to a temperature of about 12 ° C., and then cools the water cooled to the live fish tank 110 again. Discharge. The cold water supply device generates and supplies a pump 111 for forcibly sucking water from the live fish tank 110 or discharging water into the live fish tank 110, and a refrigerant for cooling the water pumped by the pump 111. Compressor 113, and a water tank 135 for storing the water pumped by the pump 111 and a refrigerant flow pipe 133 for providing a flow path of the refrigerant supplied by the compressor 113 It consists of a cooling water tank 120 for cooling the water introduced into 135.

The pump 111 is a configuration for introducing the water (sea water) of the live fish tank 110 for storing the captured fish with the sea water into the cooling water tank 120. This cold water supply device only serves to cool the water of the live fish tank 110 to a constant temperature (about 12 ℃), unlike the conventional fishing vessel. Therefore, it is possible to keep the captured fish fresh by constructing and arranging the live fish tank, that is, the cold water supply device regardless of the configuration of the fish tank. Accordingly, a conventional fishery can be used without newly reconstructing the fishery, and thus it is very useful for supplying cold water to an active fish tank (water tank) such as a small ship or a sashimi on land.

Next, the compressor 113 is to generate a refrigerant, and the cold water supply device uses the refrigerant to cool the water sucked from the live fish tank 110 by the pump 111. Accordingly, the compressor 113 generates a refrigerant. Compressor 113 is automatically turned on / off by a temperature sensor (not shown) to maintain the temperature of the water in the water tank to about 12 ℃. Fish are most activated when the water temperature is about 12 ° C.

Conventional fresh fish carriers have to cool the seawater to -1 ℃. Therefore, a large amount of energy is required and a high performance compressor is required. However, this cold water supply does not consume large amounts of energy and does not require a high performance compressor by maintaining the temperature of the water at 12 ° C where fish are best activated. Therefore, there is an advantage that the device cost and management cost is lower than the conventional device. Since the configuration of the compressor 113 is a known technique, a detailed description thereof will be omitted.

Next, the suction pipe 117 and the discharge pipe 115 is formed on one surface of the cooling water tank 120, the pump 111 is installed in the center of the suction pipe 117. Referring to FIG. 7, the cooling water tank 120 includes a water tank 135 for accommodating water, a plurality of refrigerant flow pipes 133 passing through the water tank 135, and a water tank for the refrigerant flow pipe 133. It consists of the support plate 121 provided in the both sides in the water tank 135, and the diaphragm 123 provided in three layers in the water tank 135 for support in the water tank 135. As shown in FIG.

As described above, the pump 111 is configured to pump the water of the live fish tank 110 into the cooling water tank 120, and forcibly pumps the water of the live fish tank 110 into the cooling water tank 120. The water pumped by the pump 111 flows into the cooling water tank 120 through the suction pipe 117, and the water introduced into the cooling water tank 120 passes through the discharge pipe 115 again through a predetermined process. Discharged at 110).

The water tank 135 has a receiving portion and a cover 135a, and the diaphragm 123 is installed at three places to receive water from the live fish tank 110 pumped by the pump 111, and the water tank 135 A discharge port 127 is formed at the front left side, and a suction port 125 is formed at the front right side.

The cover 135a is configured to be convenient for cleaning the cooling water tank 120. The cooling water tank 120 is easily contaminated by various microorganisms, algae, and foreign substances contained in the sea water because the sea water flows in and out. Therefore, regular cleaning is required, and at this time, after opening the cover 135a, various contaminants may be removed.

Next, the diaphragm 123 is configured to allow the water to stay in the tank 135 for a long time, but will be described later to increase the contact time between the refrigerant and the water in order to increase the cooling effect of the water. The diaphragm 123 is installed in three places in a zigzag manner such that water introduced into the water tank 135 through the suction pipe 117 is bent in the water tank 135.

In the present embodiment, the diaphragm 123 is configured in three places as shown in FIG. 7, but four or five places may be installed without following the present embodiment. However, if the diaphragm 123 is installed too much, the flow of water in the cooling water tank 120 may not be smooth, and in this case, the diaphragm may be installed at an appropriate interval and number because a high performance pump is required.

Next, the suction port 125 is a portion to which the suction pipe 117 which provides a suction path of water when the water is sucked from the live fish tank 110 is connected, and the discharge port 127 is discharged out of the water tank 135. When the discharge pipe 115 that provides a discharge path of the water is connected.

Next, the refrigerant flow pipe 133 is a configuration for providing a flow path of the refrigerant generated by the compressor 113, the cross section of the flow pipe 133 is configured as shown in FIG.

9, the refrigerant flow tube 133 is composed of two, the inner tube is the copper tube (133a), the outer tube is a stainless tube (133c). And a rubber 133b is filled between the copper tube 133a and the stainless tube 133c.

While the coolant flows into the copper tube 133a to cool the water in the water tank 135, since the copper pipe 133a has excellent thermal conductivity, in the present embodiment, the cool air of the coolant flows well into the water introduced into the water tank 135. The copper tube 133a as described above was used as a flow tube of the refrigerant to be delivered.

Next, the stainless pipe 133c is for preventing the copper pipe 133a from corrosion by the base of seawater. When the flow pipe of the refrigerant is constituted only by the copper pipe 133a, the copper pipe 133a is in direct contact with water. At this time, when the water is seawater, the copper tube 133a is easily corroded. Therefore, in this embodiment, in order to prevent such corrosion, the stainless tube 133c, which is a material resistant to corrosion, is overlaid on the outside of the copper tube 133a.

Next, the rubber 133b is for suppressing vibration. When the cold water supply device is installed on a fishing boat, the vibration or vibration caused by the progress of the fishing boat is severe, so that the noise is not generated by the vibration and the purpose of firmly supporting the copper pipe 133a. The same rubber 133b was filled.

As described above, in the present embodiment, a double pipe made of a copper pipe 133a and a stainless pipe 133c is used to provide a flow path of the refrigerant. However, if a tube made of a material resistant to corrosion and excellent in thermal conductivity is used, the refrigerant flow tube 133 may be configured as a single tube without following the present embodiment.

The refrigerant flow tube 133 is configured to travel in and out of the water tank 135 a number of times, the above-mentioned refrigerant flow pipe 133 is supported by the support plate 121 installed on both side edges of the water tank 135. A refrigerant inlet 129 is formed at the inlet of the refrigerant flow tube 133, and a refrigerant outlet 131 is formed at the outlet of the refrigerant flow tube 133. The refrigerant inlet 129 is connected to the compressor 113 for generating a refrigerant, and the refrigerant generated by the compressor 113 is introduced for the first time, and the refrigerant outlet 131 is a refrigerant flow pipe 133 inside the water tank 135. The refrigerant circulated along the flow out is a portion flowing into the compressor 113.

10 is a simplified view of the connection state of the refrigerant flow tubes 133 from the left side of the water tank 135, and the cross section and the sequence of each refrigerant flow tubes 133 and the flow direction of the refrigerant are shown. The direction of the arrow indicates the flow direction of the refrigerant. Referring to FIG. 10, the coolant flow pipes 133 are arranged in five rows of 5, 4, 5, 4, and 5 in the water tank 135. The refrigerant is introduced into the first pipe through the refrigerant inlet 129 from the compressor 113, and the refrigerant introduced into the first pipe flows to the left end across the water tank 135 and then again through the second pipe 135. Flows to the other side of the. The refrigerant introduced to the right end of the second tube is then introduced to the left side opposite the water tank 135 again through the third tube. In this way, the compressor is introduced into the compressor 113 through the refrigerant outlet 131 through the final tube.

As such, the refrigerant flow tube 133 is zigzag across the water tank 135. In this embodiment, in order to facilitate the flow of the refrigerant, the first pipe is located in one row without the arrangement of the flow pipe 133 adjacent to each other, the second pipe is located in the third row instead of the second row, and the third pipe is not the fourth row. 5 rows. In addition, the fourth pipe is located in the third column instead of the second row was configured to form a gentle curve when connected to the adjacent pipe. In this way, the flow of the refrigerant is improved.

Cooling water tank 120 composed of the above-described water tank 135, the refrigerant flow pipe 133, the support plate 121, the diaphragm 123 is capable of cooling the sea water or fresh water to supply the cold water cooled to the live fish tank. The temperature of the cold water is sensed by the temperature sensor, and automatically controls the compressor 113 to maintain 12 ℃. As a result, the water exiting the cold water supply system is 12 ° C., and when the water is introduced into the live fish tank, the fish is activated and freshness is maintained without dying.

As described above, the cold water supply device for a live fish tank according to the present invention uses a refrigerant to cool and maintain the temperature of the water at about 12 ° C. at which the fish is most activated, thereby supplying the live fish tank 110 to provide energy according to cooling. There is an advantage of low consumption of. Therefore, the equipment cost and maintenance maintenance cost becomes low, and thus, even in small fishing boats or on-site sashimi, it is possible to easily use the cold water supply system by supplying only cold water to the live fish tank without configuring a new fish tank.
