Purification method of indigo

Abstract

The invention discloses a purification method of indigo. An evaporative purification device is used in the purification method and comprises a machine body and an evaporation chamber arranged in the machine body, wherein a discharging channel is arranged in the top inner wall of the evaporation chamber in a communicating manner; a reaction chamber is arranged at the top of the discharging channelin a communicating manner; a transition channel is arranged at the bottom of the evaporation chamber in a communicating manner; a feeding cavity with a rightward opening is formed in the bottom of thetransition channel in a communicating manner; the evaporation chamber is internally provided with a heating cylinder; the heating cylinder is internally provided with a heating cavity; electric connection supporting blocks are embedded in the left and right inner walls of the evaporation chamber; an automatic butting mechanism which is electrically connected with the electric connection supporting blocks is arranged in the left end inner wall of the transition channel; the discharging channel is internally provided with a top pressure automatic discharging mechanism; a first electric motor isembedded in the top inner wall of the reaction chamber; a rotary column is in power connection with the bottom tail end of the first electric motor; spiral threads are arranged on the outer surface of the rotary column.

Description

technical field [0001] The invention relates to the technical field of indigo purification, in particular to a method for purifying indigo. Background technique [0002] With the development of science and the progress of society, the country has been promoting the development of advanced technology. Among them, there has always been a relatively difficult technical problem in the field of indigo purification technology. The general indigo purification method is to evaporate the raw materials before the reaction, and then React with lye, take out the method for the indigo of precipitation, but this kind method exists technical lack filling with general equipment, raw material is difficult for transportation, problems such as reaction precipitation is difficult for taking out, the equipment of the present invention solves this problem. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a purification method for indig...
