Extrusion-spheronization integrated granulating machine

Abstract

The invention discloses an extrusion-spheronization integrated granulating machine. A support cutter mechanism is arranged between a screw extruder and a spheronizator of the granulating machine; the support cutter mechanism at least comprises a filament propping rod, a filament and a base support; filament winding slots are formed at two ends of each filament propping rod, the filament is fixed on the filament propping rod by the filament winding slot, two ends of each filament propping rod are in clearance fitting with grooves of a pore plate by pins, a spheronization disc cover is arranged above a spheronization disc and is in clearance fitting with the spheronization disc; a spheronization feeding hole, a lifting lug and a single-screw guide groove are respectively formed in and arranged on the spheronization disc cover; the spheronization disc cover is fixed on a spheronization barrel by the lifting lug; the spheronization feeding hole and the single-screw guide groove are arranged on the outer surface and the inner surface of the spheronization disc cover respectively, the spheronization feeding hole is communicated with a through hole, the inlet and the outlet of the single-screw guide groove are communicated with the through hole and a discharge hole respectively, friction lines are formed on the upper end surface of the spheronization disc, and the base support is arranged on the spheronization disc. The extrusion-spheronization integrated granulating machine is small in occupied area, high in granulating efficiency, short in time and good in granulating effect.

Description

technical field [0001] The invention relates to the technical field of powder granulation equipment for medicine, chemical fertilizer, food, etc., in particular to an extrusion-rolling integrated granulator. Background technique [0002] Powder granulation has been widely used in the fields of pharmaceuticals, fertilizers, food, etc., and the granulation process is usually made by uniformly mixing powder raw materials, excipients, and wet binders through an extruder. Loose or agglomerated soft materials and other materials are extruded into thin round strips, and then broken and spheronized by a spheronizer to obtain wet spherical granules. At present, the current situation of powder granulation is usually performed by two independent equipment, the extruder and the spheronizer.

Problems solved by technology

[0002] Powder granulation has been widely used in the fields of pharmaceuticals, fertilizers, food, etc., and the granulation process is usually made by uniformly mixing powder raw materials, excipients, and wet binders through an extruder. Loose or agglomerated soft materials and other materials are extruded into thin round strips, and then broken and spheronized by a spheronizer to obtain wet spherical granules. At present, the current situation of powder granulation is usually performed by two independent equipment, the extruder and the spheronizer. It is difficult to realize the automatic production line operation and take up a large space. The screw extruder and the spheronizer are independent machines and equipment, which are fed manually above the screw machine. , Place a transfer container under the screw extruder. When the screw extruder is working, the long and thin columnar materials will be extruded and dropped into the transfer container. Then the transfer container will be manually moved to the vicinity of the spheronizer. When the spheronizer is running, the Manually pour the columnar material into the spheronizer, and make spherical particles under the action of breaking, spinning, centrifuging, etc. of the spheronizer, and finally manually click the "discharging" button on the operation panel to open the discharge valve of the spheronizer for discharging

The existing powder granulation technology has the following disadvantages: 1) The independent use of two machines takes up a large space in the house; 2) Manual feeding, manual turnover, and manual operation increase manpower and labor intensity; 3) Production The efficiency is extremely low; 4) The breaking and rounding effect of the spheronizer is not good, and the obtained particle size is inconsistent, easy to loose and low in compressive strength

In terms of medicines, it will cause inconvenience to subsequent drug administration; in terms of chemical fertilizers, it will cause no change to subsequent mechanized fertilization; in terms of food, feed, etc., it will bring a certain burden to subsequent storage and transportation.
