Description

Auto Continuous Smelting Device by Low & High Frequency for Clien Salt Production}

The present invention relates to an automatic continuous melting furnace apparatus for the production of clean salt using low and high frequency, which is excellent by continuously processing a large amount of salt through automatic melting, melting, cooling, and grinding through complete melting at a high temperature of 1,300 ° C or higher. The present invention relates to an apparatus for heat-treating and producing a large amount of pollution-free purified salt in a small space in a short time.

Conventional techniques for refining or processing salts are processed into ground salts, recontaminated salts, baked salts, washed salts, refined salts, and the like, and have a characteristic of melting at 800 ° C or higher due to the nature of salts. Divided into salts, the degree of use of edibles varies depending on the processing method and the purity of sodium chloride (Nacl).

As a refining method, re-salt salt (white salt, flower salt) is a method of import salt: national salt ratio of 9: 1, dissolved in water, boiled and recrystallized. Baked salt is heated in a ceramic reactor by heating stepwise for a long time according to the temperature. It removes heavy metals, but it is mixed with salt that produced a large amount of dioxin-synthesized harmful substances such as a process synthesized during incineration of waste by chemical synthesis reaction of chlorine (cl) of sodium chloride (Nacl) by aerobic combustion reaction method. Recently, the analysis revealed that there is a problem that is produced without completely removing heavy metals.

Refined salt is a recrystallization of household salt to increase the purity of sodium chloride (Nacl).

In addition, there are processed salts such as flame, beard, gold salt, earth salt, and flame depending on the use. Although these processed salts are harmful to the human body due to the technical problem of the structural device during the purification process, the present situation is that the production of harmful salt is not achieved due to the solution of the technology.

The present invention was invented to solve the above problems, and was invented to solve the problems such as the harmfulness of the human body, the complexity of the production process, the efficiency of the production, the high cost of the production facility, etc. By melting the salt under anoxic conditions, it prevents the synthesis of a large amount of dioxin such as roasted salt, and maintains high temperature of more than 1,300 ℃ in a short time. The present invention relates to an automatic continuous melting apparatus for producing clean salt using low and high frequency, characterized by transporting solid crystals and producing clean salt as an integrated type of grinding and discharging.
