Description

A kind of reaction filter drying apparatus with compression membrane
Technical field
The utility model relates to filter drying apparatus, especially relates to a kind of reaction filter drying apparatus with compression membrane.
Background technology
In the production of raw medicine process, common production process has: reaction → crystallization → filtration → washing → technological operations such as filtration → drying.Each unit operations all has units corresponding equipment in the old explained hereafter equipment, and equipment is dispersed big, and many times needs manual operations, labour intensity is big, and material is in transfer process, and open-assembly time is long, artificial pollution is serious, does not meet the requirement of GMP to pharmaceutical production.
In recent years, domestic had manufacturers produce " three-in-one " equipment, and this equipment is made up of the cylindrical shell that has chuck, agitating device, filter, can finish filtration, washing, dry three kinds of unit operations simultaneously.The characteristics of this equipment maximum are exactly blade positive and negative rotation of energy and oscilaltion, when blade turns round clockwise, can stir material, make mixing of materials even, when turning round counterclockwise, can press and grind and floating material surface, overcome breaking phenomena.In addition, blade can be made as hollow, feeds heating agent, improves drying efficiency.The major defect of this machine is: 1, owing to positive and negative the moving up and down of blade energy, so driving device structure is very complicated, in addition, the distance that blade moves up and down is difficult to be controlled; 2, by S type blade rotation discharging, discharging is not thorough.
China's utility model patent polyfunctional reactant filtering drying machine (patent No. is ZL95240476.1) is a kind of rotary equipment, form by retort, cover, stirring motor, stirring support, sealing device, filter, support and turnover transmission rig, can finish unit operations such as reaction, filtration, drying simultaneously.The characteristics of this equipment maximum are exactly when dry discharging, equipment Rotate 180 degree be made the discharging mouth down.The major defect of this equipment is: can only lean on the heat of heating agent in the chuck when 1, dry, and material mainly is positioned at the end socket place, does not but have chuck here, causes drying efficiency low; 2, no wash mill in the equipment can't be finished washing process, and the impurity in the material is easy-clear not; 3, in filter process, because shaft can't lifting not have other structure again,, occur breaking phenomena easily, thereby influence normally carrying out of filtering admittedly can not roll to filter cake.
China's utility model patent cone type reacting filtering drying machine (patent No. is ZL96229672.4) need not rotation, just can finish reaction, evaporation, concentrate, multiple-unit operations such as crystallization, filtration, drying, relatively simple for structure, form by motor and arrangements for speed regulation, frame, top cover, cylindrical shell, cone, rabbling mechanism, discharging mechanism.Main feature is: blade adopts the helical stir oar, and its shell portion blade free end is equipped with spiral scraper, and conical section blade free end is equipped with pushing spiral; All there is the composite holes expanded metals cylindrical shell and cone inboard, are made up of porous cylindrical shell or porous cone and filter medium respectively.The shortcoming of this equipment: 1, during hybrid reaction, liquid phase material can see through compound orifice plate and enter in the interlayer of orifice plate and housing, can cause the waste of liquid-phase product like this, and the crystal of reaction generation may blocking filtering medium, causes filtration difficulty; 2, this machine can't carry out crystallization operation, because crystallization crystal meeting blocking filtering medium can't carry out filtration; 3, when drying, because housing is passed in the caloric requirement in the chuck earlier, pass to compound orifice plate again from housing, pass to material by compound orifice plate, obviously depend merely on this mode, drying effect is very poor, and efficient is very low.4, in filter process, can't roll filter cake, occur breaking phenomena easily, thereby influence normally carrying out of filtering.
Chinese invention patent horizontal reacting filtering drying machine and method thereof (patent No. is 02110925.7) have been announced a kind of horizontal reacting filtering drying machine, can finish reaction, extraction, evaporation, concentrate, multiple unit operations such as crystallization, filtration, washing, drying, form by the housing of cylindrical shell, chuck, two suits, porous plate, filter medium, two drive units, agitating device, two bearing support assemblies, two axle bracing or strutting arrangements etc.This equipment main feature is that structure is horizontal, effectively reduces the equipment height overall.The shortcoming of this equipment: 1, device length is long, and the place that needs is bigger; 2, there is not cleaning function on the throne, the cleaning inconvenience between batch; 3, in filter process, can't roll filter cake, occur breaking phenomena easily, thereby influence normally carrying out of filtering.
