Description
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.
