Description
Technical field
The utility model relates to a kind of twin-screw kneader, specially refers to the twin-screw screw mixer that is used to process solid sorbitol.
Background technology
Sorbierite is separated from mountain strawberry by French Boussingault etc. and get, thus a sorbierite be applicable to and treat encephaledema and glaucoma, also can be used for the normal oedema oliguresis of cardiorenal function.It can be divided into solid sorbitol and liquid sorbitol, and the sorbitol content in the solid sorbitol is divided into different specifications generally more than 99.8% by particle diameter, is divided into pharmaceutical grade and food-grade by purposes.Liquid sorbitol is divided into food-grade and technical grade by purposes.Food-grade can be used as food, toothpaste NMF; Technical grade is mainly used to produce vitamin C.Food-grade is divided into by the content difference of sorbierite: the liquid sorbitol of sorbitol content 50% and 70% liquid sorbitol.
Liquid sorbitol is processed in the process of solid sorbitol, what general local method adopted is: liquid sorbitol is poured in the reactor, utilize Steam Heating, sorbierite liquid in the reactor is constantly stirred, the water vapour evaporation, become Neosorb after the cooling, make varigrained sorbierite crystal grain through pulverizing.This processing way can cause production process discontinuous, and efficient is not high, and labour intensity is big.
Summary of the invention
For solving above technical deficiency, the utility model provides a kind of efficient height, and is time saving and energy saving, can be as the kneader of processing solid sorbitol.
The utility model is realized by following measure:
A kind of twin-screw kneader of the present utility model, comprise power drive system, charging system, control system, lubricating system, cooling system, extrusion system and former, described extrusion system comprises machine barrel and is set in parallel in two interior screw rods of machine barrel, described machine barrel one end is communicated with charging system, the other end is communicated with former, and two screw rods drive respectively to be connected and drive on its axial rotation power drive system.
Above-mentioned screw rod comprises screw mandrel and plurality of sections screw unit, and described screw unit is connected on the screw mandrel by spline housing, changes screw unit according to different behaviours in service, thereby uses replacing convenient flexibly.
In order to improve mixing effect, also be connected to the kneading piece on the above-mentioned screw mandrel by spline housing.
The place, axle center of above-mentioned screw mandrel is provided with axial water circulation cavity, and described water circulation cavity is connected with cooling system, can lower the temperature for screw rod.
Be provided with water circulation channel in the barrel of above-mentioned machine barrel, described water circulation channel is connected with cooling system, can quite satisfactory machine barrel cooling.
In order to adapt to different job requirements, above-mentioned screw unit comprises the plurality of sections that pitch is different with length, and its screw thread is single head or double end.
In order to make the screw rod cooling effect better, above-mentioned water circulation cavity length is 4/5 of a screw mandrel length.
The beneficial effects of the utility model are: adopt this twin-screw kneader, changed the mode of production of conventional solid-state sorbierite, not in the higher reactor processing method of use cost, adopt twin-screw, the extruding mixing effect is better, make production convenient, production process is continuous, the efficient height, and cost is low, time saving and energy saving, hygienic environment-protecting.

The specific embodiment
Shown in Fig. 1,2,3,4,5,6, a kind of twin-screw kneader of the present utility model comprises power drive system 1, charging system 2, control system 3, extrusion system 4, former 5, cooling system 6 and lubricating system 7.Extrusion system 4 is cores of this technology, mainly comprise machine barrel 8 and two screw rods that are set in parallel in the machine barrel 8, two screw rods drive by speed-changing gear box and are connected on the power drive system 1, and under the driving of power drive system 1, two screw rods rotate in machine barrel 8.Machine barrel 8 one ends are communicated with charging system 2, and the other end is communicated with former 5.
Screw rod comprises screw unit 10 and screw mandrel 9, screw unit 10 comprises the plurality of sections of different pitch and length, also designed the kneading piece 11 of stirring action, mediate the profile approximate ellipsoidal of piece 11, above element center processing spline, screw mandrel 9 processing splines, screw unit 10 and kneading piece 11 and screw mandrel 9 are connected by spline.The link position of screw unit 10 can change arbitrarily.
6 pairs of machine barrels 8 of cooling system and screw rod all can cool off in the work.Place, axle center at screw mandrel 9 is provided with axial water circulation cavity, length is 4/5 of screw mandrel 9 length, the water pump of cooling system 6 pushes water circulation cavity with cooling water and flows out in the cooling system from water circulation cavity the inner, forms circulation, reaches the purpose of cooling screw.Process water circulation canal in the barrel of machine barrel 8 feeds the circulation canal of machine barrel 8 by water pump with cooling water, reaches the purpose of cooling machine barrel.
