Further, a kind of preferred version of the present utility model is: described oscillating plate is 15～30cm apart from the distance of top plate.
Further, a kind of preferred version of the present utility model is: described air sparger is installed on 15～30cm place, interlayer tube sheet below.
Further, a kind of preferred version of the present utility model is: the length that described vibrating head is inserted in the heat exchanger tube is 3/4～4/5 of heat exchanger tube.
The beneficial effects of the utility model:
1, crystallization time (cycle) is shorter, general 8 hours/batches.The utility model and existing crystalline phase ratio.Crystallization time is shorter, owing to be provided with special shaking device and gas mixer in the equipment, makes crystallization time shorten greatly, and stirred crystallization speed is fast more than stationary crystallization.
2, the discharging mother liquor is fast, and the amount much less
Because the effect of shaking device and air sparger makes the interior crystal of heat exchanger tube grow up to tubular film.And the awl drilling that the lower end aperture is big than the upper end is beneficial to mother liquor and discharges fast.With existing crystallization tube sheet ratio, crystal is long real in tube bank, forms solid column, and mother liquor is difficult to discharge.Only when heating up, crystal column external cause constantly fusing is discharged with mother liquor.Therefore, crystallization discharging mother liquor of the present utility model is measured much less soon.
3, yield reaches height
Need not to melt crystal in a large number when discharging owing to mother liquor discharges.Therefore, batch yield reaches 75～85%, and existing crystallizer is high by 4%～5%.
4, product purity height
Crystal forms the tubulose epitaxial in the utility model, is beneficial to mother liquor and discharges, and form high-purity crystal.Existing crystallizer then crystallizes into solid column crystal column.Be unfavorable for the mother liquor discharge.Be surrounded by a large amount of mother liquors in the crystal column, thereby purity is lower, has only 99.5%, the tubulose epitaxial then is conducive to mother liquor discharges, and forms high-purity crystal, purity 〉=99.8%.
5, operating cost is low
Because crystallizing cycle is short, row's mother liquor is thorough, the product yield height.Therefore, the existing crystallizer of operating cost compares low 40%.
