As shown in FIGS. 1 to 4, the salt production apparatus of the present invention includes a salt water supply means 100 for spraying salt water of 20% or more salt in a mist form, and a hot air generating means for generating hot air by heating it to 300 ° C. or more ( 200), the salt water sprayed from the salt water supply means 100, and the hot air supplied from the hot air generating means 200 meet to evaporate moisture to form a salt generating unit provided with a space (S) inside (S) ( 300) and a control unit (c) for controlling the salt water supply means 100 and the hot air generating means 200 .

The salt manufacturing apparatus according to the present invention having the above configuration may be fixedly installed on the frame 500 by connecting and installing a plurality of frames in the horizontal and vertical directions. A caster 510 may be movably installed at a lower portion of the frame 500 .

In the above description, brine with a salinity of 20% or more means that a certain amount of water is evaporated by trapping seawater.

The reason why the salt water supply means 100 sprays salt water with a salinity of 20% or more in the form of mist is that the moisture of the salt water sprayed in the mist form by the hot air generated by the hot air generating means 200 to be described below is quickly removed. This is to shorten the time for salt crystallization by evaporation.

The configuration of the brine supply means 100 is, as shown in FIG. 3 , a brine storage tank 110 for storing brine, a pump 120 for pumping brine from the brine storage tank, and the pump 120. It consists of a salt water supply pipe 130 in which a nozzle 140 is installed at the outlet for supplying the pumped salt water to the space S of the salt generator 300 .

And the configuration of the hot air generating means 200, as shown in FIGS. 3 and 7, a heating furnace 210 provided with a heater for heating the inside together with electricity supply, and blowing air into the heating furnace 210 It consists of a blower 220 for generating hot air, and a hot air supply pipe 230 for supplying hot air from the heating furnace 210 to the space S of the salt generator 300 .

And as shown in FIGS. 1 and 2, the salt generator 300 has an internally sealed space (S) provided therein, and an opening and closing door 350 capable of opening and closing the space (S) is installed on the front side.

The reason for installing the opening and closing door 350 on the front of the salt generating unit 300 is to visually check and manage the space (S) and to clean the inside of the space (S).

In addition, the hot air supply pipe 230 and the salt water supply pipe 130 are installed to be in contact with each other along the longitudinal direction as shown in FIG. 3 , so that the hot air supply pipe 230 is transferred to the salt water supply pipe 130 It was formed to supply the heat-exchanged brine to the space (S) of the salt generating unit 300 as the heated and brine is heat-exchanged.

As the brine heat exchanged by receiving the heat of the hot air supply pipe 230 as described above maintains the heat above room temperature, the hot air is supplied when the salt water above room temperature is supplied to the space S of the salt generating unit 300 in the form of mist. As the water evaporates more rapidly by the hot air supplied to the tube 230, the salt crystallization time is accelerated.

The salt produced as described above is accumulated on the floor of the space (S), and hot air is supplied in the form of mist and discharged to the outside through the outlet 370 in a humidified state while evaporating the moisture of the salt water.

On the other hand, in the vicinity of the brine supply means 100, as shown in FIG. 3, a washing water storage tank 410 having a washing water supply pipe 420 installed on one side is installed, and the washing water supply pipe is the pump 120 ), but at the neck where the washing water supply pipe 420 and the brine supply pipe 130 meet, the supply of washing water is blocked when the brine is supplied, and the supply of brine is blocked when the washing water is supplied. 430 is installed so that the washing water or salt water proceeds along the salt water supply pipe 420 installed to be in contact with the hot air supply pipe 230 and into the space S of the salt generator 300 through the nozzle 140 configured to be supplied.

And when brine is supplied to the neck where the washing water supply pipe 420 and the brine supply pipe 130 meet, the supply of washing water is cut off, and when the washing water is supplied to the brine supply pipe 130, a valve 430 that blocks the supply of brine. ) is installed, when the brine of the brine storage tank 110 is supplied to the brine supply pipe 130 to produce salt, when the washing water of the washing water storage tank 410 is supplied, the salinity is lowered. When the washing water of the washing water storage tank 410 is supplied to the brine supply pipe 130, if the brine water of the brine storage tank 110 is supplied, the washing of the brine supply pipe 130 and the nozzle 140 cannot be performed. because it does

When supplying the brine of the brine tank 110 to the brine supply pipe 130, salt is made in the space S, and when supplying the washing water of the washing water storage tank 410 to the brine supply pipe 130, the brine supply pipe It is preferable not to operate the hot air generating means 200 when supplying the washing water as it is for washing the 130 and the nozzle 140 , but if necessary, the hot air generating means 200 may be operated.

In addition, the outlet portion of the hot air supply pipe 230, as shown in Figs. 5 and 6, is installed in the upper part of the space (S) of the salt generating unit 300, and the hot air supply is installed bisectedly. The nozzle 140 is installed inside the discharge port located at the upper part of the discharge port of the pipe 230 because the salt water of the salt water storage tank 110 is in the form of a mist through the nozzle 140 in the space (S). When supplied, the hot air is supplied in the same direction as the brine at the same time so that the water evaporation of the brine is quickly performed, so that the salt crystallization can be made quickly and more effectively.

In addition, the outlet of another hot air supply pipe 230 was formed at the lower part of the outlet of the hot air supply pipe 230 in which the nozzle 140 is installed. When the salt water supplied to S) does not completely evaporate and falls in the form of water droplets, this is to evaporate the moisture of the falling water droplets so that the salt can be effectively crystallized.

The outlet of the hot air supply pipe 230 bisectically installed on the inner upper portion of the space S of the salt generator 300 is formed by branching from one hot air supply pipe 230 outlet.

And it is preferable that the portion in contact with the hot air supply pipe 230 and the salt water supply pipe 130 is positioned inside the duct (D) to keep heat.

In addition, an opening and closing door 240 having a space therein is installed on one side of the heating furnace 210 as shown in FIG. 7 , and between the internal space of the opening and closing door 240 and the blower 220 , the heat in the internal space of the opening and closing door is blown A heat transfer pipe 250 for transferring to 220 is installed, and the reason is that the air supplied into the heating furnace 210 through the blower 220 is supplied as preheated air to the inside of the heating furnace 210 . This is to save energy by minimizing the energy consumption of the heater that heats the inside of the heating furnace 210 by minimizing the heat loss.

In addition, on the exit side of the space (S) of the salt generating unit 300, as shown in FIGS. 2 and 8, a first partition wall 310 with an open lower portion and a closed upper portion and both side walls is installed, and the first At the rear of the partition wall, a second partition wall 320 with an open upper portion and closed lower and both side walls is installed to be maintained at a predetermined distance from the first partition wall 310, so that the first partition wall 310 and the second partition wall 320 are installed. A stagnant part 330 is provided between the stagnant parts 330 between the rear surface of the first partition wall 310 and the front surface of the second partition wall 320, and in the stagnant part 330, downward from the upper rear surface of the first partition wall to the lower front surface of the second partition wall. A stagnation guide plate 340 having a plurality of holes formed with an inclination is installed.

As described above, the first bulkhead 310 and the second bulkhead 320 are installed at the exit side of the space (S) of the salt generator 300 to be spaced apart to provide a stagnant part 330, and a plurality of The reason for installing the stagnation guide plate 340 having a hole in the salt generating unit 300 is that when all the moisture in the salt water supplied in the form of mist is not evaporated and discharged to the outside, the production efficiency of salt is reduced. By lowering, the stagnant portion 330 and the stagnation guide plate 340 reduce the speed of the hot air so that the final salt is determined in the stagnant portion 330 .

The principle of stagnation by the above configuration is that the primary stagnation is made while the salt water and hot air proceed to the lower open part of the first partition wall 310 into the space S, and the stagnation guide plate of the stagnant part 330 ( 340), secondary stagnation is made, and as the upper part of the second bulkhead 320 progresses through the opening, tertiary stagnation is formed.

In addition, an upper rail 311 is installed in the width direction of the stagnation guide plate 340 on the rear upper portion of the first bulkhead 310 where the stagnation guide plate 340 is installed, and the stagnation guide is provided at the lower front of the second bulkhead 320 . The lower rail 321 is installed in the width direction of the plate 340 so that the upper and lower ends of the stagnation guide plate 340 slide along the respective rails 311 and 321 and are installed to be separated and coupled. At 330, salt is determined, and when the hole of the stagnation guide plate 340 is blocked, it is to clean the blocked hole.

In addition, on the bottom surface of the space (S) of the salt generating unit 300, as shown in FIG. 6, a transfer screw 360 for discharging the salt produced in the space (S) to the outside is installed, and one of the transfer screws A driving means for rotating the transfer screw 360 is installed on the side.

Therefore, the salt produced in the space (S) is accumulated on the bottom surface of the space (S) of the salt generating unit 300 , and the accumulated salt is discharged to the outside through the transfer screw 360 .

On the other hand, as shown in FIG. 5 on the bottom surface of the space (S) of the salt generating unit 300, the opening and closing door 350 may be opened and salt may be taken out without installing the transfer screw 360. As such, the opening and closing door 350 ) is opened and salt is taken out, it is preferable to form a concave shape so that salt is collected on the bottom surface of the space (S) of the salt generator 300 .

In addition, a control unit (C) is installed at a position adjacent to the salt generating unit 300 of the present invention, the control unit is a drive to rotate the salt water supply unit 100, the hot air generating unit 200, and the transfer screw 360 controlling the means.

As described above, in the salt manufacturing apparatus of the present invention, as described in the above effect, salt water having salinity is sprayed in the form of mist, and hot air is applied to the sprayed salt water so that water evaporates and salt crystals are quickly made. It is simple, easy and quick to manufacture, and when you want to stop after salt production is complete, wash each tube and nozzle with brine to produce salt with washing water to prevent clogging of each tube and nozzle at the same time. It has the advantage of being able to extend the service life of the salt manufacturing apparatus according to the present invention by preventing corrosion.
