Method for preparing purified indigo blue

Abstract

The invention discloses a method for preparing purified indigo blue, involving a device main body and a centrifugal device arranged in the device main body, wherein the centrifugal device comprises afirst cavity formed in the device main body and having an upward opening, a second cavity is formed in the inner wall of the lower side of the first cavity, a first slide block is slidably arranged inthe second cavity, a third cavity with a rightward opening is formed in the first slide block, a first motor is fixedly arranged in the inner wall of the right side of the second cavity, the left endof the first motor is in power fit connection with a first cam, extending into the second cavity, by a rotary shaft, and the upper and lower ends of the first cam are respectively abutted against theinner walls of the upper and lower sides of the second cavity. The invention aims to design the method capable of automatically smashing indigo blue and squeezing indigo blue juice therein.

Description

technical field [0001] The invention relates to the technical field of pigment preparation, in particular to a method for preparing purified indigo. Background technique [0002] In the preparation of indigo, indigo leaves need to be piled up, watered frequently, and fermented for several months to form black soil lumps, which are called ball indigo after being compacted with a mortar. Wood ash, lime and bran are mixed into the indigo ball. Add water and stir, heat to 30-40°C, and expose to the air to become blue insoluble indigo. At this time, the staff needs to use a filter bag to filter out the indigo juice from the square for the next step, but in this step need to use The personnel squeeze by hand, so the hands and clothes of the user are easy to be dyed and the operation remains unchanged. Therefore, a method for preparing purified indigo that can automatically crush the indigo and squeeze out the indigo juice is designed. It is necessary. Contents of the invention ...
