Abstract

Disclosed is a stirring type alkali fusion reaction still for producing H-acid. The stirring type alkali fusion reaction still comprises a still body, a stirring device is installed on the still body and comprises a stirring shaft which is installed on the axis of the still body, a power device is arranged at the upper end of the stirring shaft, an anchor stirring device is arranged at the bottom end of the stirring shaft, and at least two stirring blades are arranged at the bottom end of the stirring shaft. According to the stirring type alkali fusion reaction still for producing the H-acid, stirring qualities are improved, heating-up time of materials is shortened, the conversion ratio of the materials is improved, and qualities of the H-acid are improved.

Description

Be used to produce the stirring-type alkali fusion agitated reactor of H-acid
Technical field
The utility model relates to H-acid production technical field, is specifically related to the stirring-type alkali fusion agitated reactor that uses in a kind of H-acid production.
Background technology
H-acid is claimed 1-amino-8-naphthol-3 again, the 6-disulfonic acid; It is important naphthalene series dye intermediate; It is mainly used in and produces directly, acid, reactive dye and azo dyes intermediate, like acid day blue, direct kind surplus the black Reactive Brilliant Red K-2BP etc. 90, also can be used for industry in the pharmacy.
At present, skill generally is to be raw material with the refined naphthalene in the production of domestic H-acid, makes through operations such as sulfonation, nitrated, neutralization, reduction, alkali fusion and acid outs.Alkali fusion procedure need utilize the alkali fusion agitated reactor to carry out, and in the alkali fusion agitated reactor, stirring whether fully be a key point that influences H-acid quality.Though existing alkali fusion agitated reactor is provided with agitating device; But an anchor formula paddle is set all generally; Though anchor formula paddle can stir the inner feed liquid of alkali fusion agitated reactor; But be difficult to realize stirring up and down of feed liquid, so mixing quality do not reach requirement, cause the product quality of H-acid to can not get improving.
The utility model content
The utility model technical problem to be solved provides the stirring-type alkali fusion agitated reactor that is used to produce H-acid, and it can pass through effectively to improve the product quality of the mixing quality of feed liquid with raising H-acid, thus defective in the elimination above-mentioned background technology.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
Be used to produce the stirring-type alkali fusion agitated reactor of H-acid; Comprise kettle, said kettle is equipped with agitating device, it is characterized in that; Said agitating device comprises that rotation is installed on the shaft on the said kettle axis; The upper end of said shaft is provided with power-equipment, and the bottom of said shaft is provided with anchor agitator, and the bottom of said shaft also is provided with at least two stirring vanes.
As a kind of improvement, said power-equipment comprises variable-frequency motor, and said variable-frequency motor can change the mixing speed of agitating device.
As a kind of improvement, the bottom of said shaft is provided with two stirring vanes of arranging up and down, and said stirring vane can make the inner feed liquid of kettle produce flow-disturbing, thereby mixing quality is more reliable.
Owing to adopted technique scheme, the beneficial effect of the utility model is:
The stirring-type alkali fusion agitated reactor that the utility model provides is applicable to the H-acid production process, and the bottom of its shaft is provided with anchor agitator; Also be provided with at least two stirring vanes simultaneously; Based on this structure, the alkali fusion agitated reactor not only can utilize anchor agitator to realize conventional stirring, and can utilize stirring vane to make the inner feed liquid of kettle produce flow-disturbing up and down; Improved the quality that stirs; Thereby shortened the heating-up time of material, improved the conversion ratio of material, improved the product quality of H-acid.
The stirring-type alkali fusion agitated reactor that the utility model provides; Adopt the power-equipment of variable-frequency motor as agitating device; The rotating speed of variable-frequency motor can be adjusted; Based on this structure, the alkali fusion agitated reactor can be optimized adjustment to mixing speed according to actual needs, with the product quality of further raising H-acid.
The stirring-type alkali fusion agitated reactor that the utility model provides, stirring vane has two, is arranged in the bottom of shaft up and down; Based on this structure; Stirring vane can make the inner feed liquid of kettle produce flow-disturbing, thereby mixing quality is more reliable, has shortened the heating-up time of material; Improve the conversion ratio of material, improved the product quality of H-acid.
Description of drawings
Accompanying drawing is the utility model structural representation;
Among the figure: 1. kettle, 2. agitating device, 21. shafts, 22. power-equipments, 23. anchor agitators, 24. stirring vanes.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Shown in accompanying drawing, be used to produce the stirring-type alkali fusion agitated reactor of H-acid, comprise kettle 1; Said kettle 1 is equipped with agitating device 2; It is characterized in that said agitating device 2 comprises that rotation is installed on the shaft 21 on said kettle 1 axis, the upper end of said shaft 21 is provided with power-equipment 22; The bottom of said shaft 21 is provided with anchor agitator 23, and the bottom of said shaft 21 also is provided with at least two stirring vanes 24.The alkali fusion agitated reactor not only can utilize anchor agitator 23 to realize conventional stirring; And can utilize stirring vane 24 to make kettle 1 inner feed liquid produce flow-disturbing up and down; Improved the quality that stirs; Thereby shortened the heating-up time of material, improved the conversion ratio of material, improved the product quality of H-acid.
In the present embodiment, said power-equipment 22 is selected variable-frequency motor for use, and variable-frequency motor can change mixing speed, according to actual needs mixing speed is optimized adjustment, with the product quality of further raising H-acid.
In the present embodiment, the bottom of said shaft 21 is provided with two stirring vanes of arranging up and down 24, and said stirring vane 24 can make kettle 1 inner feed liquid produce flow-disturbing, thereby mixing quality is more reliable.
The utility model is not limited to the above-mentioned specific embodiment, and all are based on the technical conceive of the utility model, and the structural improvement of having done all falls among the protection domain of the utility model.
