Special novel furnace for refining bamboo salt and black bamboo salt

Abstract

The invention relates to a special novel furnace for refining bamboo salt and black bamboo salt. The special novel furnace mainly comprises a bamboo salt crucible, a molten iron crucible and an intermediate frequency furnace; the bamboo salt crucible is of a vertical cylindrical cavity structure, and an open mouth is formed in the top of the bamboo salt crucible; the molten iron crucible is of a cylindrical cavity structure coaxially nested in the bamboo salt crucible, the outer part of the bottom of the molten iron crucible is fixedly connected with the interior of the bottom of the bamboo salt crucible, and the top of the molten iron crucible is provided with an open mouth; and the intermediate frequency furnace is internally provided with a cylindrical furnace chamber vertically, and the bamboo salt crucible is coaxially nested in the furnace chamber of the intermediate frequency furnace. The purpose of the special novel furnace is to produce high-quality bamboo salt and black bamboo salt by maintaining the temperature of the furnace at 1000 -1400 DEG C for three to five hours through the intermediate frequency furnace.

Description

technical field [0001] The invention relates to a special novel kiln for refining bamboo salt and purple bamboo salt. Background technique [0002] Bamboo salt has a long history in China. It is prepared from bamboo and raw salt after many times of calcination. The obvious effect of human rehabilitation. [0003] When producing bamboo salt through traditional kilns, in order to increase and stabilize the temperature of the kiln to 1000-1400 degrees Celsius, good sealing performance is required, and the heat cannot be lost due to ventilation and exhaust, so the temperature will drop; but due to the tightness It may also be due to the inability to control the temperature of the kiln freely. When the temperature rises sharply, the bamboo salt may gasify and evaporate, which will cause the pressure of the sealed kiln to lose control, cause an explosion and cause an accident, so an open type is needed. The new kiln is used to calcinate bamboo salt, which can keep the temperatur...

Problems solved by technology

[0003] When producing bamboo salt through traditional kilns, in order to increase and stabilize the temperature of the kiln to 1000-1400 degrees Celsius, good sealing performance is required, and the heat cannot be lost due to ventilation and exhaust, so the temperature will drop; but due to the tightness It may also be due to the inability to control the temperature of the kiln freely. When the temperature rises sharply, the bamboo salt may gasify and evaporate, which will cause the pressure of the sealed kiln to lose control, cause an explosion and cause an accident, so an open type is needed. The new kiln is used to calcinate bamboo salt, which can keep the temperature of liquid bamboo salt at 1000-1400 degrees Celsius for three to five hours, and because it does not need to be sealed, it prevents accidents from happening
