Description
Technical field
The utility model relates to agricultural products process equipment field, is specially a kind of rotary granulation device.
Background technology
Granulation is a kind ofly for improving powder flowbility, to make relatively fine particle be agglomerated into the technique of meal granule, the material of the states such as powder, fused solution, the aqueous solution through being processed into the operation with definite shape and big or small shot-like particle.The preparation process of nearly all solid pharmaceutical preparation all be unable to do without pelletization, and made particle may be final products, as granule; Also may be intermediate products, as tablet.The operation of granulating makes particle have certain corresponding purpose, for example, to guarantee carrying out smoothly of product quality and production: in granule, capsule, particle is product, the object of granulating is not only mobility, dustability, the adhesion in order to improve material and is conducive to accurate measurement, protection production environment etc., and the shape size that must guarantee particle evenly, good looking appearance etc.; And particle is intermediate in tablet manufacturing, not only to improves liquidity to reduce the weight differential of tablet, and will guarantee the compact property of particle.
Granulation, as indispensable technical process in solid pharmaceutical preparation production, has special meaning in corresponding preparations is produced.Although current solid pharmaceutical preparation is granulated to produce and emerged many novel dry method and wet granulation equipment, traditional oscillating granulator is still no lack of for classical process equipment, and it has certain practicality.Yet, along with updating and pharmacy corporation improving constantly equipment requirement of various granulation standards, traditional oscillating granulator and rotary granulator can not be applicable to current pharmaceutical technology requirement, mainly because there is following shortcoming for oscillating granulator: the silk screen of use adopts nylon yarn tightly to wrap in and waves, nylon yarn serious wear, the fiber hybrid wearing and tearing, in material, and adopts stainless steel wire Netease to produce to slip silk, fracture of wire phenomenon; The long grain of making is to disconnect by the deadweight of particle, so the gap of particle (two Head of particle) thins down to corner angle, and loose, and in dry and minute process of assembling, losing rib, to produce powder amount large, and fine powder is exceeded standard; Dead angle, granulation chamber is many, not easy cleaning; Easily enter powder and pollute bearing.For rotary granulator, have following shortcoming: granulation chamber is columnar, dead angle situation has larger improvement than oscillating granulator, but still has hold-down screw on the base plate of granulation chamber; The curved portion of granulating cutter pressing materials is short, and large with the angle of wedge of screen drum inner circle, granulating cutter is little to the extruding force of material, to increase the extruding force of granulating cutter to material with improving granulating cutter rotating speed, because granulating cutter rotating speed is very fast, the gap of granulating cutter and screen drum is large, occurs that at work material accumulates in the friction of inboard wall of riddle drum thick layer material and granulating cutter and generates heat; In pelletization, fall on the receiver of inclination and all under blow-by, carry out with particle.
Utility model content
The purpose of this utility model is to provide a kind of production efficiency high, good airproof performance, and easy to clean, granulates evenly, is difficult for the rotary granulation device into powder in motor bearings.
A kind of rotary granulation device of the utility model, comprises cabinet 1, is arranged on the transmission device of cabinet 1 inside, the granulation device that is arranged on cabinet 1 top and is connected with transmission device, and granulation device top is connected with back taper feed hopper 2; It is characterized in that, described granulation device comprises screen drum 3, is arranged on the granulating cutter 4 of screen drum 3 central interior, and corresponding granulating cutter 4 is arranged on the cutter 5 of screen drum 3 outsides; Described transmission device comprises interconnective motor 6 and reductor 7; Reductor 7 is provided with outer output shaft and the interior output shaft of switched in opposite; It is inner that interior output sleeve is located at outer output shaft, and be connected with granulating cutter 4; Outer output shaft is connected with screen drum 3 bottoms by positioning plate 8.
Further, described granulation device also comprises screen drum upper cover 9 and the water conservancy diversion pressing plate 10 that is arranged on screen drum 3 tops; Screen drum upper cover 9 is connected with feed hopper 2 by water conservancy diversion pressing plate 10.
Further, described cutter 5 are fixedly installed on the knife rest 11 being connected with cabinet 1, and outer setting has the blow tank 12 of ring-type.
Further, the bottom of described blow tank 12 is provided with discharge nozzle 13, and inside is provided with the scraper plate 14 that is connected to positioning plate 8 outer rims.
Further, a side of described feed hopper 2 is fixedly connected with cabinet 1 by the column 15 being arranged on cabinet 1.
A kind of rotary granulation device of the utility model, it has the following effect of having a mind to:
(1) by granulating cutter 4 being arranged on to the central interior of screen drum 3, make the curved portion of granulating cutter 4 pressing materials elongated, little with the angle of wedge of screen drum 3 inner circles, the extruding force of 4 pairs of materials of granulating cutter is large, thereby granulating cutter 4 is lower with screen drum 3 relative rotation speeds, granulating cutter 4 is little with the gap of screen drum 3, thereby make to accumulate material bed thin at screen drum 3 inwalls, the heat producing with granulating cutter 4 frictions is little, thereby avoided material accumulate screen drum 3 inwalls produce thick material bed and with the phenomenon of granulating cutter 4 frictional heatings, guarantee the uniformity and the quality of granulating.
(2) by granulating cutter 4 is connected with outer output shaft with the interior output shaft of switched in opposite in reductor 7 respectively with screen drum 3, make granulating cutter 4 contrary with positioning plate 8 direction of rotation, because the gap between granulating cutter 4 and positioning plate 8 is very little, be equivalent to clearance seal one, add in reductor and be also provided with sealing, therefore, when granulating operation, can guarantee material in screen drum 3 can not enter in the bearing of reductor 7 and pollute bearing, good airproof performance, and be convenient to clean long service life.
(3) by the screen drum 3 outer setting cutter 5 in corresponding granulating cutter 4, when material forms circle shape bar under the effect of screen drum 3 and granulating cutter 4, cutter 5 are just cut to graininess, owing to adopting cutter 5 to cut, not only make particle length consistent, and otch is neat, in dry and minute process of assembling, losing rib, to produce powder amount little; Simultaneously owing to being provided with blow tank 12, and the sealing of whole device arranges, so in pelletization, and the scraping delivery of particle in blow tank 12 be all to carry out under sealing, and production efficiency is high, and granulate quality is good, pollution-free.
