Abstract
A titration control device for preparing big pills with more than 70 mg of pill weight comprises eight parts, namely a gas transmission pipe (1), a pressure regulating meter (2), a dropping liquid tank (3), a transfusion switch (4), a compressed air pressure and frequency regulator (5), a pneumatic control valve (6), a dripper (7) and a cooling column (8). The pneumatic pulse output from the compressed air pressure and frequency regulator acts on the pneumatic control valve, the dripper valve is switched according to the preset frequency, the flow of the liquid medicine output from the dripper tank is accurately controlled, the liquid medicine is dripped into the high-viscosity cooling agent of the cooling column and naturally contracted into pills by surface tension, and the large dropping pills which have the pill weight difference of more than 70 mg to 300 mg and are smoothly formed and meet the requirements of pharmacopoeia can be obtained.
Description
Affiliated technical field
The present invention is a kind of dripping control device that ball weighs the large dripping pillar more than 70 milligrams of manufacturing, and belongs to medical mechanical field.
Background technology
Drop pill is the classical dosage form of solid dispersion technology, has to absorb soon, and advantages such as bioavailability height are the developing direction of modern Chinese medicine.But, because existing drop pill machine can only be produced the following drop pill of 100mg mostly, dose is significantly increased, the patient has been brought inconvenience.Therefore, the above large dripping pillar production equipment of the heavy 70mg of ball includes the primary study development track in.The mold cools down of employing molding mode, plunger displacement pump extrusion way and large aperture water dropper pressure controling mode are arranged therebetween, but because of complex structure, the cost height, the product ball is heavy uneven, and molding is not round, all fails to satisfy user's needs, the production of can't finalizing the design.
Summary of the invention
The present invention is existing big, in, on the basis of small-sized drop pill machine, set up dripping control device, by adjustable decompression gas circuit, air control unit, compressed air pressure and frequency regulator that vacuum control loop and programmable timing circuit are formed, accurately drip system by the Hysteresis for Pneumatic Control Valves water dropper that connects in the dropping liquid tank bottom, drop pill is increased to about 70-300mg below the heavy 70mg of present ball, and the ball method of double differences is different little, the molding slyness, can reach country's " pharmacopeia " standard, expanded the drop pill production field greatly, positive impetus has been played in the development of modern Chinese medicine.
The large dripping pillar dripping control device is made up of appendix, voltage regulating meter, dropping liquid tank, transfuse switch, compressed air pressure and frequency regulator, pneumatic control valve, water dropper and cooling column eight parts.
Pneumatic control valve is by receiving from the air pulsing of compressed air pressure and frequency regulator output, by predefined frequency switching water dropper valve, control is from the flow of the medicinal liquid of dropping liquid tank output, and medicinal liquid splashes into and relies on surface tension to shrink molding naturally in the cooling column high-viscosity coolant.
A dripping control device can be controlled a water dropper, also can control several water droppers.
Temperature heating regulation and control will be arranged at cooling column top.Can be fixed, a plurality of water droppers drip system; Also can rotate, a water dropper drips system fast.
Figure of description
Among the figure 1, appendix 2, voltage regulating meter 3, dropping liquid tank 4, transfuse switch 5, compressed air pressure and frequency regulator 6, pneumatic control valve 7, water dropper 8, cooling column
The specific embodiment
Medicinal liquid is heat tracing in dropping liquid tank (3), opens transfuse switch (4) messenger drug liquid stream and goes into water dropper (7); Start compressed air pressure and frequency regulator (5), by the switch of appendix (1) control pneumatic control valve (6), medicinal liquid oozes in the coolant that falls into cooling column (8) by the frequency of setting, and relies on surface tension to be shrunk to ball naturally in liquid coolant.
Claims (9)
1, a kind of dripping control device of manufacturing large dripping pillar is characterized in that: be made up of appendix, voltage regulating meter, dropping liquid tank, transfuse switch, compressed air pressure and frequency regulator, pneumatic control valve, water dropper and cooling column eight parts.
