Chitosan oligosaccharide chelated ferrous preparation method and device

Abstract

The invention provides a chitosan oligosaccharide chelated ferrous iron preparation device which comprises a first-stage mixing pipe, a second-stage mixing pipe and a mixing pool which are sequentially arranged from top to bottom, and the mixing pool is further connected with a suction filtration device; one end of the first-stage mixing pipe is connected with a water inlet pipe through a flow switch, the upper part of the first-stage mixing pipe is also provided with a feeding box for quantitative feeding, a plurality of stirring structures for mixing fed objects with water are arranged in the first-stage mixing pipe, and the other end of the first-stage mixing pipe is connected with the side wall of the second-stage mixing pipe; a plurality of first-stage mixing pipes are distributed on the second-stage mixing pipe, the first-stage mixing pipes are symmetrically arranged on the two sides of the second-stage mixing pipe, and a plurality of first mixing plates which are obliquely arranged upwards are arranged on the side wall, close to the first-stage mixing pipes, of the second-stage mixing pipe; the mixing effect can be remarkably improved through the first-stage mixing pipe, the second-stage mixing pipe, the stirring structure and the mixing pool structure, and a well-mixed and PH-value-adjusted mixed solution is automatically and continuously provided for the suction filtration device.

Description

technical field [0001] The invention relates to the field of chitosan oligosaccharide chelation, in particular to a method and device for preparing chitosan oligosaccharide chelated ferrous iron. Background technique [0002] In the preparation process of oligochitosan chelated ferrous iron, it is necessary to obtain an aqueous solution of oligochitosan and ferrous sulfate solution respectively. When the powder material is mixed with water, the powder material is easy to float on the water surface due to the tension of the water. The traditional preparation method is through Manual stirring and mixing, or stirring equipment for mixing. When mixing by manual stirring, there will be differences due to human differences, and the preparation time is long. When mixing by stirring equipment, the stirring shaft will push the water surface during the rotation process, so that it floats on the water surface The powder object is pushed far away, and it also takes a long time to mix co...
