Summary of the invention
The objective of the invention is in order to overcome the defective of prior art, a kind of electronic grade chemicals crystallizer simple in structure, practical, effective is provided, to satisfy the needs that the crystallization of electron-level phosphoric acid chemicals is produced.
To achieve these goals, technical scheme of the present invention is following:
A kind of electronic grade chemicals crystallizer comprises crystallizing tank, and agitator, said crystallizing tank adopt high-purity plastics as liner; Said crystallizing tank has steel bustle pipe and/or chuck outward; Said crystallizing tank is provided with 3～5 materials and adds inlet; Said crystallizing tank tank skin has 2～4 eyesights; Said crystallizing tank tank skin also has 2～4 thermometer patchholes; Said agitator adopts the variable frequency adjustment pattern, the through crystallizing tank of said agitator shaft bottom, and be connected with scraper plate in the shaft bottom.
Improve as the present invention, be equipped with aperture on the said scraper plate.
Crystallizer provided by the invention has following characteristics:
(1) crystallizing tank adopts high-purity plastics as liner, reaches anticorrosion, clean effect;
(2) external steel bustle pipe and/or the chuck done of crystallizing tank feeds medium, the effect that reaches cooling or heat up;
(3) crystallizing tank is provided with a plurality of materials and adds inlet, is convenient to that raw material adds, cleanser adds, crystal seed adds and crystallizing tank cleans, and reaches the effect of better formation crystal;
(4) the crystallizing tank tank skin has eyesight, is convenient to observe at any time crystallization effect;
(5) agitator adopts the variable frequency adjustment pattern, can change the agitator frequency according to the characteristics of crystal forming process, so that the crystalline form of crystallization control, and reaches the effect of purification.
(6) the through crystallizing tank of the shaft of crystallizer bottom, and connect stirring scratch board in the shaft bottom, help the blanking and the cleaning of crystal; Avoided the phenomenon of the blocking pipe of crystal in the blanking process.
A kind of electronic grade chemicals crystallizer provided by the invention uses proof through reality, has reached predetermined purpose, is applicable to the needs of electronic grade chemicals crystal production, especially is applicable to electron-level phosphoric acid chemicals crystal production.
