Description
Technical field
The utility model belongs to stirring technique field, is related to the crystallizer of medical product, the crystallizer especially suitable for
The crystallization process of antibiotics drug.
Background technique
Traditional vertical crystallizing tank generally uses anchor formula and frame type stirring.Anchor formula stirs one that general diameter of propeller blade is tank diameter
Half or more, flow pattern category Radial Flow is stirred, few to stir phenomenon up and down, crystallizing tank is afraid of that crystal is attached on baffle in addition
On, therefore it is not baffled, this is difficult to the homogeneity for reaching tank skin and tank center solution temperature and upper and lower material concentration.In small canister
Interior anchor formula stirring is still able to satisfy requirement, but as tank volume amplifies, the quality of crystallization just has a declining tendency.It is larger for viscosity
With easy glutinous wall and for having the crystal solution of non-Newtonian, when anchor formula stirring can not play effect at the tank skin of top, Zhi Nenggai
Use frame type stirring.Frame type stirring is few to stir up and down since flow pattern still belongs to Radial Flow, and revolving speed is extremely low.And common axis
To stream agitated crystallizer, revolving speed is higher, and it is higher that there are local energy-dissipations, is easily broken crystal, and needs with baffle, commonly
Baffle is easy to hang crystal, and bottom be easy to cause the deposition of crystal and reunites, if it is high that there are difficulty of processing using W type bottom, at
This higher disadvantage.For a long time, conventional crystallizer volumes are difficult to amplify, and affect the scale development and product of pharmaceuticals industry
The raising of quality.
Summary of the invention
The utility model provides a kind of high-efficiency mould suitable for medical product, solves glutinous wall, the deposition of material, obtains
Ideal crystal grain size and distribution, and energy conservation.
The utility model solve technical solution used by above-mentioned technical problem be to provide it is a kind of suitable for medical product
High-efficiency mould, including be located at kettle mouth mounting flange top motor, gear reducer, shaft coupling, rack and mechanical seal and
Agitating shaft and blender for extending into crystallization kettle etc., design has feed inlet on the top kettle wall of crystallization kettle, and bottom design has out
Material mouth.Blender includes the bottom blender positioned at the axial flow stirrer at middle part and positioned at lower part, on the upside of near-bottom blender
First layer axial flow stirrer around be mounted with guide shell, the position of the side wall upper part of guide shell is mounted with material-feeding port, and correspondence is led
The kettle wall diameter of flow cartridge height gradually decreasees from top to bottom, and crystallization kettle section is in contraction-like.It is configured with scraper plate on bottom blender,
Scraper plate is uniformly distributed 3~5 pieces on bottom blender, every piece of diameter of propeller blade for being along the radical length of blender, and width is 200~
300mm, thickness meet intensity requirement.The design of crystallization kettle inner wall has triangular baffle, and quantity is 3~4 pieces.Axial flow stirrer packet
Blade, connecting plate and wheel hub are included, blade is fixed on wheel hub by connecting plate, and the width of blade is 0.4~0.5 times of diameter,
It is punched above blade, 5~10mm of aperture, percent opening is 10~25%, and effect is best when 15%.
The utility model has the advantages that: efficient axial-flow blender cooperation guide shell is capable of forming relatively good whole circulation,
So that the mixing ratio of material is more uniform, and the blender has the quasi- number of discharge capacity high, the function of low sheraing；Blender aperture can arrive
Play enhancing local turbulence and energy-efficient effect；Crystal can be effectively prevented in bottom settlings group in the scraper plate that bottom blade has
It is poly-；The diminution in guide shell cooperation crystallization kettle section causes crystal high in the flow velocity of bottom, is conducive to crystal nucleation, the overhead stream of kettle
Speed is slower, is conducive to the growth of crystal, and the particle of the crystal of formation is bigger, is distributed narrow；Triangular baffle avoids material from beating
It can be cohered again to avoid crystal while rotation.
