Description

{Manufacturing Apparatus for Salt from Sea Water}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a salt production apparatus using sea water, and more particularly, to a salt production apparatus using seawater for producing salt by removing foreign matter from seawater and heating it to separate water.

Generally, in order to obtain salt, sea water is introduced into a salt water tank, and it is trapped in a water tank. Then, it is naturally dried with solar heat and wind to obtain salt crystals, or sea water is filled into a large pot, and a large pot is burned with wood, coal, And there is a method in which salt is evaporated by heating to produce salt.

The salt produced in salt tanks is spontaneously evaporated and the production period of salt is long, so production disruption due to changes in the weather of rain and snow is severe, and it takes up a large area of land to produce salt.

In addition, a large pot is heated by fossil fuel to produce salt, which is conventionally used by the ancestors. The seawater contained in a large pot is heated to about 600 ° C. by using fossil fuel to evaporate water, . The use of this method in modern times is not desirable because of the cost of fossil fuels and the secondary loss of environmental pollution due to the use of fossil fuels, which is not appropriate due to the large time requirements. Further, if the sea water is heated at a high temperature of 600 ° C, lumpy salt is produced, so that additional processing such as grinding or grinding the salt mass may be required.

In addition, a method of drying a relatively non-woven fabric such as a non-woven fabric to evaporate salt water by natural sunlight and wind has been developed. However, it is difficult to remove the impurities contained in the salt, A problem may arise.

The transfer pipe 100 is formed with a seawater inlet 110 through which the seawater is introduced and a seawater introduced through the seawater inlet 110 is moved through the transfer pipe 100 to produce a salt S And a salt discharging portion 160 through which the produced salt S is discharged is formed on the other side.

The seawater is moved from the sea to the seawater inlet 110 through the seawater pipe 10 and the seawater pipe 10 may be provided with a seawater pump 12 for transferring the seawater to the seawater inlet 110 side.

2 is a view showing a foreign matter removing unit of a salt production apparatus using seawater according to an embodiment of the present invention.

The seawater inflow section 110 may be provided with foreign matter removing units 112 and 114. As shown in FIG. 2, the foreign matter removing units 112 and 114 are mesh networks, and the foreign substances contained in the seawater can be separated while the incoming seawater passes through the foreign matter removing units 112 and 114. In this embodiment, the first foreign matter removing unit 112 and the second foreign matter removing unit 114 provided downstream of the first foreign matter removing unit 112 are installed in the seawater inflow unit 110, The spacing of the meshes is formed more closely than the distance between the first foreign material removing part 112 and the first foreign material removing part 112 so that particles having a large particle size are separated from the first foreign material removing part 112, Small foreign objects can be separated.

The transfer pipe (100) may be provided with a transfer pump (120) for transferring seawater.

3 is a view illustrating a heavy metal removal unit of a salt production apparatus using seawater according to an embodiment of the present invention.

As shown in FIG. 3, the transport pipe 100 may be provided with a first heavy metal removal unit 130. In this embodiment, the first heavy metal removing unit 130 is a magnet, and the ferrous metal that has not been removed from the first foreign substance removing unit 112 and the second foreign substance removing unit 114 can be separated from the seawater. An opening 102 is formed in the periphery of the first heavy metal removal unit 130 to discharge the heavy metal separated by the first heavy metal removal unit 130 to the outside of the transfer pipe 100, A cover 104 for opening and closing the cover 104 may be installed. The cover 104 may be of a hinged type or of a sliding type. Thereby, the cover 104 can be opened to remove the heavy metal remaining in the conveyance pipe 100 through the opening portion 102.

On the transfer pipe 100, a heating unit 140 for heating seawater flowing through the transfer pipe 100 may be provided. The seawater in which various foreign substances and heavy metals are separated from the first foreign material removing unit 112, the second foreign material removing unit 114 and the first heavy metal removing unit 130 moves to the heating unit 140 through the transfer pipe 100 . In this embodiment, the heating unit 140 is a band heater 140, and may be coupled to the outside of the conveyance pipe 100 in a band form. A plurality of band heaters 140 may be coupled to each other so as to be spaced apart from each other within a predetermined interval of the transfer tube 100. In this embodiment, the temperature of each band heater 140 may be set to 188 캜. 188 ° C is the temperature at which the best quality salt can be obtained by heating seawater. Thereby, as the seawater passes through the plurality of band heaters 140, water can be evaporated and the salt S can be generated.

A steam discharge pipe 150 branched from the transfer part may be provided downstream of the heating part 140. The water evaporated in the heating unit 140 can be discharged to the outside of the transfer pipe 100 through the steam discharge pipe 150.

In this embodiment, the sinkers 310 and 320 may include a first settling tank 310. First, the moisture discharged through the steam exhaust pipe 150 is received in the first settling tank 310, and foreign substances contained in the moisture can be precipitated. The moisture separated from the first settling tank 310 may be discharged to the outside through the discharge pipe 312. The discharge pipe 312 may be provided with a valve 314 for controlling the discharge of water from the first settling tank 310. The water discharged from the first settling tank 310 can be used as agricultural water.

Alternatively, the sinkers 310 and 320 of the present embodiment may further include a second settling tank 320. In the second settling tank 320, the water discharged from the first settling tank 310 through the discharge pipe 312 may be received and the second settled. Thereby, the residual foreign matter contained in the water can be separated. The moisture separated from the foreign substances in the second settling tank 320 can be used as potable water.

Meanwhile, the salt S produced through the salt discharging unit 160 of the transfer pipe 100 may be discharged. The salt S discharged to the outside through the salt discharging unit 160 can be received in the salt receiving unit 200.

4 is a view showing a salt receiving portion of a salt production apparatus using seawater according to an embodiment of the present invention.

4, the salt receiving part 200 may include a first salt receiving part 210 and a second salt receiving part 220 in this embodiment. The first salt accommodating portion 210 is a component in which the salt S1 discharged through the salt discharging portion 160 is primarily accommodated. A salt discharge pipe 212 through which the salt S1 is discharged may be connected to one side of the first salt receiving unit 210. On the salt discharge pipe 212, a second heavy metal removal unit 214 may be provided. That is, the heavy metal contained in the salt S1 discharged from the first salt receiving part 210 through the salt discharge pipe 212 can be separated by the second heavy metal removal part 214. [ A magnet may be applied to the second heavy metal removing unit 214 as in the first heavy metal removing unit 130. Thus, the salt S2 from which the heavy metal is removed is finally discharged by the second heavy metal removing unit 214, and the finally produced salt S2 can be received in the second salt receiving unit 220
