Description

Apparatus For Making Ice From Seawater Or Ozonewater}

The present invention relates to a seawater and ozone water ice maker for producing ice by freezing seawater, and more particularly, after storing the seawater introduced from the outside into a freezing tube formed in a cylindrical tube shape, the entire outer surface of the freezing tube The seawater rapidly freezes by bringing the cryogenic coolant into contact with each other to increase the area in contact with the coolant.

In addition, by melting the surface of the frozen ice using a high-temperature, high-pressure refrigerant supplied from the discharge side of the compressor, the ice is lowered by its own weight to automatically cut to a relatively constant size by a cutter installed in the lower portion It relates to a seawater to ozone water ice maker.

In general, the storage method for maintaining the freshness of seafood can be largely divided into a refrigerated storage method using a refrigerator and an ice storage method using ice.

Here, in the case of the refrigerator storage method using the refrigerator, when an unexpected power failure occurs during the operation of the refrigerator, the seafood in storage is easily decayed, excessive power is required for refrigeration storage, and refrigerated due to the dehumidifying effect of the freezer. Moisture in the stored seafood is reduced and drying occurs.

In addition, if you want to move the seafood to another area, there is a problem that excessive maintenance costs are required because a vehicle equipped with a separate refrigeration device is to be used.

On the other hand, the ice storage method using the ice is mainly used to store the seafood and ice filled in a wooden box or styrofoam box.

However, in the case of using a wooden box in the summer, the outside temperature is high, the ice filled in the wooden box during the cold storage process of seafood is easily melted due to contact with the outside has a disadvantage of low refrigeration efficiency.

In addition, in the case of using a styrofoam box, since the contact with the outside is relatively blocked, the melting of ice is delayed as much as possible, and the ice is melted and accumulated in the styrofoam box, so that moisture is supplied to prevent the seafood from drying out. .

However, as time goes by, the ice melts little by little, and when the dissolved ice water accumulates in a large amount inside the box, the salinity of the seafood is gradually lowered due to the osmotic pressure caused by the stagnant water, and the freshness of the seafood is inhibited and the corruption is reduced. There is a problem that acts as a facilitating factor.

The present invention was created in order to solve the above-mentioned problems, by using the ice frozen in seawater (salt) instead of ordinary water (fresh water) to fill the styrofoam box, the seawater ice in the process of storing seafood Even though it is melted by the external temperature, the molten water contains salt, thereby delaying the rot of the seafood due to the osmotic phenomenon, thereby maintaining the freshness of the seafood as much as possible.

In a seawater to ozone water ice maker that manufactures ice using a coolant supplied from a coolant supply unit including a compressor, a condenser, a heat exchanger, a receiver, a liquid separator, and an expansion valve, a coolant through a coolant inlet connected to the coolant supply unit. And an ice making unit including a freezing tank in which the freezing tank is introduced and stored therein, and a through-hole formed inside the freezing tank in the form of a cylindrical tube and having at least one freezing pipe in which seawater or ozone water is introduced and stored from the outside. ; A refrigerant gas detection unit connected to one side of the ice making unit and detecting a temperature or pressure of the refrigerant gas flowing out of the ice making unit; And a lower cover part positioned below the ice making unit and cutting the cylindrical ice frozen in the freezing pipe at a predetermined interval using a cutter, and selectively sealing the lower part of the freezing tank by using one side of the cutter.

The refrigerant supply unit may further include a high temperature refrigerant gas control valve for controlling a refrigerant inflow amount so that the refrigerant gas at room temperature supplied from the compressor flows into or out of the freezing tank of the ice making unit.

In addition, the ice making unit preferably further comprises an air outlet for discharging the internal air raised from the inside of the freezing tube to the outside by the seawater or ozone water introduced into the bottom of the freezing tube.

Further, the lower cover portion is further characterized in that the cutter is installed in the vertical direction with the freezing tube, the cutter motor is connected to the cutter to provide power to enable the cutter to reciprocate in the horizontal direction.

In addition, the expansion valve of the refrigerant supply unit controls the inflow of the refrigerant stored in the freezing tank to freeze in a state in which a predetermined through-hole is formed in the ice based on the temperature or pressure of the refrigerant gas detected in the temperature reduction unit. It is preferable to characterize.

In addition, the refrigerant supply unit, the ice making unit, the ice control unit and the lower cover portion may be installed on one side of the vessel.

According to the seawater ice machine of the present invention,

First, since ice is melted using sea water, even though ice is melted by an external temperature, the molten water contains salinity, thereby preventing salt leakage of the seafood by osmotic pressure, thereby maintaining the freshness of the seafood.

Second, since the cryogenic refrigerant liquid is introduced and heat exchange is performed over the entire outer surface of the freezing tube, the contact area for cooling is increased, and thus there is an advantage that rapid freezing is possible.

Third, faster ice making is possible than conventional ice making machines, and a large amount of ice can be obtained within a short time.

Fourth, the frozen ice is lowered by its own weight, and is automatically cut to a predetermined length or a desired length by the cutter, thereby maximizing user convenience.

Fifth, since normal ice making is possible even when installed on one side of the ship, it is possible to manufacture and use seawater ice in real time by taking seawater directly from the sea after catching it, without having to load extra ice on the ship. In the case of ocean fishing boats, by reducing the weight of ice loaded during movement, it has the effect of reducing transportation costs.

Sixth, since the control does not completely freeze the seawater in the freezing pipe, there is an advantage that the freezing pipe does not have to be frozen.

Is a partial cutaway perspective view showing the structure of the ice making unit according to an embodiment of the present invention.

Sea water to ozone water ice maker 100 according to an embodiment of the present invention is the refrigerant supply unit 110 and the ice making unit 150, refrigerant gas detection unit 130 and the lower cover portion 140 as shown in Figs. It is provided, including.

Here, the structure and operating principle of the refrigerant supply unit 110 will be described first.

Referring to FIG. 1, the refrigerant supply unit 110 includes a compressor 111, a condenser 112, a heat exchanger 113, a fluid receiver 114, a liquid separator 115, and an expansion valve 120. do.

In the refrigerant supply unit 110 as described above, the high temperature and high pressure refrigerant gas compressed through the compressor 111 flows to the oil separator 116 through a discharge tube, and the refrigerant gas contained in the refrigerant gas is separated from the oil separator 116. The refrigeration oil is separated from the refrigerant gas and sent back to the compressor 111 so as not to be introduced into the condenser 112, and the refrigerant gas separated from the refrigerant oil flows to the condenser 112.

In the condenser 112, the refrigerant gas is heat-exchanged by air cooling by air or water cooling by water to liquefy the refrigerant liquid.

In addition, the liquefied refrigerant liquid flows to the heat exchanger 113 through the discharge tube, and heat exchanges with the low temperature refrigerant gas flowing from the heat exchanger 113 to the compressor 111 to decrease the temperature.

Subsequently, the refrigerant liquid of the heat exchanger 113 flows through the discharge tube and is stored in the receiver 114, and the refrigerant liquid required by the ice making unit 150 of the stored refrigerant liquid is transferred to the liquid separator 115. It is flowed, heat exchanged again in the liquid separator 115, and supplied to the expansion valve 120 as refrigerant liquid of a lower temperature.

Here, the liquid separator 115 functions to separate the refrigerant liquid from the refrigerant gas sucked into the compressor 111 and to prevent the refrigerant liquid from flowing into the compressor 111 to be compressed.

The refrigerant liquid that has passed through the liquid separator 115 flows into the lower portion of the ice making unit 150 through the refrigerant inlet A 117a, and the introduced refrigerant liquid passes through the filter drier 122 to contaminate the foreign matter contained in the refrigerant liquid. This is removed, and flows into the expansion valve 120 through the refrigerant liquid electron valve 121.

At this time, the expansion valve 120 supplies the refrigerant liquid to the inside of the freezing tank 151 to lower the pressure and temperature to facilitate the heat absorption by the evaporation of the refrigerant liquid, and at the same time appropriate to the fluctuation of the refrigeration load It is in charge of controlling and supplying refrigerant flow rate.

Therefore, the refrigerant liquid having passed through the expansion valve 120 is supplied into the freezing tank 151 of the ice making unit 150 through the refrigerant inlet B 117b in a state of extremely low temperature and low pressure.

Here, in the freezing tank 151 between the refrigerant inlet A (117a) and the refrigerant inlet B (117b), the refrigerant liquid flowing from the liquid separator 115 and the refrigerant liquid flowing from the expansion valve 120 are separated. Separator plate 158 is provided to be stored.

The separator 158 serves to prevent the lower portion of the freezing tank 151 from being frozen by an extremely low temperature refrigerant liquid introduced through the expansion valve 120.

Meanwhile, the refrigerant liquid introduced into the freezing tank 151 is evaporated by heat exchange with the seawater stored in the freezing pipe 152 located inside the freezing tank 151, and the evaporated refrigerant gas is formed on the upper portion of the ice making unit 150. It flows out through the formed refrigerant gas outlet 132 and flows to the compressor 111 via the liquid separator 115 and the heat exchanger 113.

Here, one side of the refrigerant gas outlet 132 of the ice making unit 150 is connected to the refrigerant gas detector 130 for detecting and measuring the temperature or pressure of the refrigerant gas flowing out from the freezing tank 151.

The refrigerant gas detection unit 130 detects the temperature or pressure inside the freezing tank 151 which is lowered when the seawater is frozen in the freezing tank 151 to measure the temperature or pressure in a separate controller (not shown). Pass in a value.

The controller (not shown) controls the high temperature refrigerant gas control valve 118 to prevent seawater from freezing when the measured value reaches a reference set value described later based on the measured value of the temperature or pressure. Thus, the high-temperature, high-pressure refrigerant gas flowing out of the compressor 111 is introduced into the freezing tank 151 to increase the temperature of the refrigerant liquid stored in the freezing tank 151.

Additional description of the control unit (not shown) will be described later.

On the other hand, one side of the refrigerant gas detection unit 130 is provided with a temperature sensing unit 123 is filled with a predetermined gas therein, the temperature sensing unit 123 is a freezing tank through the refrigerant gas outlet 132 ( Sensing the temperature of the refrigerant gas flowing out of the 151, the predetermined gas is provided to expand and contract according to the temperature change of the refrigerant gas.

In addition, one side of the temperature sensing unit 123 and one side of the expansion valve 120 is connected to the capillary tube 124, the capillary tube 124 is a thin copper tube formed with a through-hole in the center, the inside of the temperature sensing unit 123 It serves as a passage for allowing the gas filled in the delivery to the expansion valve (120).

More specifically, when the temperature of the refrigerant liquid of the freezing tank 151 increases due to the introduction of high temperature refrigerant gas or heat exchange between the seawater and the refrigerant liquid, the temperature of the refrigerant gas detected by the temperature reduction part 123 is increased. As the temperature rises, the gas filled in the temperature reduction part 123 expands due to the elevated temperature.

Therefore, the expanded gas is delivered to the expansion valve 120 along the capillary tube 123, the expansion valve 120 is closed by the expanded gas is to block the inflow of the refrigerant liquid.

On the other hand, when the inflow of the high temperature refrigerant gas is completed and the temperature of the refrigerant liquid of the freezing tank 151 is lowered again, the temperature of the refrigerant gas detected by the temperature reduction unit 123 is lowered, and by the lowered temperature The expanded gas inside the temperature reduction part 123, the capillary tube 123, and the expansion valve 120 is contracted, and the closed expansion valve 120 is opened and the refrigerant liquid is introduced again.

Due to the combination and operation of the expansion valve 120, the temperature sensing unit 123, and the capillary tube 124 as described above, the expansion valve 120 is the amount of refrigerant flow in accordance with the change in the internal temperature of the freezing tank 151 It is provided to be adjusted.

Meanwhile, the hot refrigerant gas flowing out of the compressor 111 and flowing through the oil separator 116 flows through a separately provided discharge tube instead of the refrigerant supply line flowing to the condenser 112 to control the high temperature refrigerant gas. In accordance with the control of the valve 118 is provided to be introduced into the freezing tank 151 of the ice making unit 150 through the refrigerant inlet B (117b).

Here, the high temperature refrigerant gas control valve 118 is controlled by the control unit (not shown), and is closed at the ice making time when the ice is frozen by the cryogenic refrigerant in the freezing tank 151, so that the high temperature refrigerant Blocks the flow of gas, and during the defrosting time when the frozen ice is separated from the inside of the freezing tube 152, the state is opened, and the refrigerant gas flowing in the compressor 111 flows into the inner surface of the freezing tube 152. It is preferably controlled to melt the surface of the ice in contact with it.

Next, a structure in which the ice making unit 150 and the lower cover part 140 are combined will be described.

1 to 3, the ice making unit 150 includes a freezing tank 151 in which refrigerant is introduced into and stored inside the refrigerant inlet B 117b connected to the refrigerant supply unit 110, and the freezing tank ( Located in the interior of the 151 is formed in the form of a cylindrical tube, the through-hole formed therein is provided with at least one or more ice pipes 152 to be stored in the sea water from the outside.

Here, in FIG. 2, only two freezing tubes 152 are illustrated to clearly express the structure of the freezing tube 152. However, the present invention is not limited thereto, and the quantity, vertical height, and inner diameter of the freezing tube 152 are manufactured. It is preferable that the ice size is determined in consideration of the specification of the ice to be introduced into the freezing tank 151 and the temperature and pressure.

In addition, one side of the lower portion of the freezing pipe 152 is provided with a seawater inlet 155 through which seawater is introduced from an external seawater source, and seawater for controlling the supply of seawater between the seawater source and the seawater inlet 155. The liquid electron valve 154 is provided.

In addition, the other side of the lower portion of the freezing pipe 152 is provided with a water level detection unit 153 for detecting the amount of seawater supplied by the seawater is supplied with the freezing pipe 152.

When the water level detection unit 153 detects that the preset inflow of seawater is supplied, the water level detection unit 153 transmits a full water signal to the seawater liquid valve 154, and the seawater liquid valve 154 is the signal. Shut off the supply of seawater on the basis of

When seawater flows into the lower portion of the freezing pipe 152 through the seawater inlet 155, the seawater rises from the bottom of the freezing pipe 152 to the top, and the internal air inside the freezing pipe 152 is filled with seawater. It is pushed by the rising, the upper air is discharged to the outside through the air outlet 156 formed in the upper end of the ice making unit 150.

Therefore, the internal air does not remain in the seawater filled in the freezing pipe 152, and since the vacuum space by the bubble is not formed during freezing, the discharge of the frozen seawater ice in the freezing pipe 152 is smooth. Become.

On the other hand, a lower cover portion 140 including a cutter 141, a cutter motor 142, and a water tank 145 is provided below the ice making unit 150.

4 is an exploded perspective view illustrating a structure in which the cutter 141 and the cutter motor 142 are coupled to each other.

Referring to FIG. 4, the cutter 141 is coupled to the cutter motor 142 through the link 143 and the bearing 144, and the rotating shaft 146 of the cutter motor 142 is one end of the link 143. It is inserted through and inserted into the insertion hole 147b formed in the portion.

In addition, the insertion shaft 147a formed at one side of the other end of the link 143 is inserted into the through hole formed at the center of the bearing 144 to be rotatable, and the bearing 144 is the cutter 141. It is inserted into the guide groove 148 formed in one side of the coupled to the reciprocating movement in the guide groove 148.

Therefore, the link 143 coupled to the rotation shaft 146 of the cutter motor 142 by the rotational force of the cutter motor 142 rotates with the rotation shaft 146 around the insertion hole 147b, By the rotational force of the link 143, the bearing 144 reciprocates in the guide groove 148 and rotates about the insertion hole 147b, whereby the cutter 141 has the freezing pipe 152. It will reciprocate in the horizontal direction perpendicular to).

Here, the cutter 141 is a plate-shaped member, the cutting surface is formed on one side is provided to cut the ice falling vertically from the freezing pipe 152 by the cutting surface, but not limited to this is formed of a separate cutting surface It is preferable that the ice is also cut by one side end of the cutter 141 without this.

Meanwhile, the upper surface of the cutter 141 has an annular sealed packing 157 provided at the lower end of the ice making unit 150 so that the lower end of the ice making unit 150 is sealed when the sea water enters the sea water inlet 155. It is fixed to be in close contact with the ice to form a predetermined closed space 149 in the lower portion of the freezing pipe 152.

Therefore, the seawater flowing into the seawater inlet 155 is filled up without rising into the freezing pipe 152 and the water level detection unit 153.

Next, the operating principle of manufacturing ice in the seawater to ozone water ice maker 100 of the present invention will be described.

Referring to FIGS. 1 and 2, first, seawater is supplied from an external seawater source under control of the seawater electromagnetic valve 154, and the sealed space 149 and the ice pipe of the ice making unit 150 are provided through the seawater inlet 155. Flows to the bottom of 152.

At this time, the lower part of the ice making unit 150 is sealed by one side of the cutter 141 and the sealed packing 157 does not leak the seawater, and the introduced seawater is freezing pipe 152 and the water level detection unit 153 ) Is filled upwards from the lower end.

Here, the internal air inside the freezing pipe 152 is pushed upward by the incoming seawater, and is discharged to the outside through the air outlet 156 formed at the upper end of the ice making unit 150.

In addition, the vertical height of the seawater filled in the water level detection unit 153 and the freezing pipe 152 is the same, and the water level detection unit 153 is a seawater flows by a predetermined height of the seawater (inflow of seawater), the seawater A full water signal is sent to the liquid electron valve 154, and based on the signal, the sea water liquid electron valve 154 blocks the seawater supply line so that no more seawater flows in.

As such, when seawater is filled in the freezing pipe 152, the refrigerant liquid is introduced into the lower portion of the freezing tank 151 through the refrigerant inlet A 117a formed at the lower portion of the ice making unit 150.

The refrigerant flowed in through the filter drier 122, the refrigerant fluid electron valve 121, and the expansion valve 120, the temperature and pressure drops to a low temperature, low pressure to the refrigerant inlet B (177b) of the freezing tank 151 It is preferable that the flow rate of the refrigerant liquid flowing into the inside is determined in consideration of the height of the seawater filled in the freezing pipe 152.

Expansion valve 120 is the expansion valve 120 is automatically opened and closed by the expansion and contraction action of the gas filled in the temperature reduction unit 123 according to the temperature change in the freezing tank 151, the ice freezing Adjust the flow of refrigerant until it is complete.

Thereafter, the seawater filled in the freezing pipe 152 and the refrigerant liquid filled in the freezing tank 151 rapidly freeze seawater due to heat exchange, and the refrigerant liquid partially evaporates into the refrigerant gas, and the refrigerant gas evaporated. The suction is sucked into the compressor 111 through the liquid separator 115 and the heat exchanger 113 through the refrigerant gas outlet 132 formed in the upper portion of the freezing tank 151.

On the other hand, the sea water filled in the inside of the freezing pipe 152, while the outer surface of the freezing pipe 152 is in direct contact with the coolant, freezing starts from the outer surface of the freezing pipe 152 toward the center, a predetermined time At this initial freezing time, seawater close to the inner surface of the freezing pipe 152 is frozen, and the seawater located at the center of the freezing pipe 152 is in an unfrozen seawater (liquid) state.

After a certain time has elapsed again, the seawater located in the central portion is frozen, and the seawater filled in the freezing pipe 152 is completely frozen.

However, when the seawater filled in the freezing tube 152 by the refrigerant liquid introduced into the freezing tank 151 completely freezes, the freezing tube 152 is freezes and is damaged due to an increase in the volume of the frozen ice. There is concern.

Therefore, in the seawater to ozone water ice maker 100 of the present invention, in order to prevent freezing of the above-mentioned ice pipe 152, the seawater inside the ice pipe 152 is an intermediate step from the freezing to the complete freezing. The outer periphery of the seawater is frozen (ice) and the center portion is frozen (sea water), that is, the seawater is cooled to freeze in a cylindrical ice state with a hole formed in the center.

As a result, while the seawater freezes inside the freezing pipe 152, the volume of the seawater expands in the direction of the unfrozen seawater in the center of the freezing pipe 152 by the inner surface of the freezing pipe 152. Tube 152 is not freezing.

On the other hand, in order to freeze the cylindrical ice with a through-hole formed in the center as described above, by measuring the pressure and temperature of the refrigerant gas evaporated and outflowed in the freezing tank 151, based on the measured pressure and temperature value You can judge the degree of ice freezing.

This is because the coolant liquid is controlled by the expansion valve 120 and flows into the freezing tank 151 to start heat exchange with the seawater inside the freezing pipe 152. The latent heat of water is initially generated during the heat exchange. The pressure and temperature inside the freezing tank 151 rapidly decreases until all of them are discharged to start freezing. However, when freezing starts, the amount of heat to be exchanged is greatly reduced, and the pressure and temperature gradually decrease.

Thus, by measuring the pressure and temperature inside the freezing tank 151 gradually decreases as the sea water begins to freeze as described above, it is possible to check the degree of freezing of the sea water, the degree of freezing of the sea water desired by the user (inside the ice) The size of the through hole) can also be determined empirically through repeated pressure and temperature measurements.

As a result, a pressure value or a temperature value of the refrigerant gas flowing out of the refrigerant gas outlet 132 when the seawater is frozen in the ice state in which the air is formed in the freezing tank 151 is set as a reference value, and then the freezing tank ( When the seawater is frozen again in 151, the seawater is frozen until the pressure or temperature of the refrigerant gas at the refrigerant gas outlet 132 reaches the reference set value. It is frozen in the formed state.

On the other hand, as described above, when the pressure or temperature value of the refrigerant gas detected by the refrigerant gas detection unit 130 reaches the preset reference set value, the controller (not shown) is a high temperature refrigerant gas control valve 118 is controlled to open the hot refrigerant gas supplied from the compressor 111 to be introduced into the freezing tank 151.

At the same time, the controller (not shown) controls the cutter motor 142 to move the cutter 141 sealing the lower portion of the ice making unit 150 in one direction to open the lower portion of the ice making unit 150, The cutter 141 provides a power source to reciprocate in the horizontal direction.

Therefore, the temperature of the refrigerant liquid inside the freezing tank 151 increases due to the inflow of the high temperature refrigerant gas, and the temperature rises between the inner surface of the freezing tube 152 and the outer surface of the ice by the elevated temperature. The ice is lowered by its own weight as the frictional force due to freezing disappears.

At this time, the temperature reduction unit 123 is the gas inside the temperature reduction unit 123 is expanded by the internal temperature of the freezing tank 151 raised by the inflow of high-temperature refrigerant gas, the expanded gas is a micro-tube 124 It is transmitted to the expansion valve 120 through the expansion valve 120 is closed, so the refrigerant flow is blocked.

 In addition, the ice is lowered in a vertical direction with the cutter 141, is cut at a relatively constant interval by the cutter 141 is stacked on a separate ice storage unit (not shown) located in the lower portion of the ice making unit 150. do.

Here, when the cutter 141 moves in one direction and the lower portion of the ice making unit 150 is exposed, the seawater stored in the predetermined closed space 149 descends to the lower portion and flows into the water tank 145. It is preferable that the seawater is introduced into an ice storage unit (not shown) so that ice is not thawed.

When the ice is lowered and the inside of the freezing pipe 152 is emptied as described above, the controller (not shown) controls the high temperature refrigerant gas control valve 118 to block the inflow of the high temperature refrigerant gas, and the cutter ( 141 stops the reciprocating motion and closes the lower part of the ice making unit 150 again, and the seawater is introduced from the seawater source under the control of the seawater liquid valve 154 as in the initial stage of supplying the seawater.

On the other hand, the seawater to ozone water ice maker 100 of the present invention is preferably provided to enable installation and operation on one side of the ship moving the sea as well as the land.

Therefore, the seawater to be frozen with ice is connected directly to the seawater intake pipe connected to the seawater inlet 155 to seawater (sea), without having to load the vessel separately, and control of the seawater liquid valve 154 when ice is required. As a result, ice can be obtained by inflowing seawater.

In addition, the inner diameter of the freezing tube 152 of the present invention is not only formed relatively narrow, but also filled with seawater to fill the inside, even if the ship is inclined left and right by the waves can be normal ice making.

In addition, in the embodiments of the present disclosure, the ice making water used for the seawater to the ozone ice maker is described as being limited to the seawater, but is not limited thereto, and it is of course possible to make ice using ozone water or general fresh water (fresh water).

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains.
