As kneading and extrusion are integrated into an organic whole, the unexpected physical and chemical performance changes of the mixed materials in the circulation process, after the mixed materials are discharged form the kneader, which can influence the later granulation or even cause interruption of the later operation, are avoided; the granulation productivity and product quality are improved.
Description
Technical field
The present invention relates to a kind of Granulation Equipments, specifically a kind of kneading extruding and granulating equipment.
Background technology
Existing Granulation Equipments and kneader device, extrusion equipment generally are mutually independently.Particularly between kneader device and the extruding and granulating equipment, on technology, belong to the process equipment of adjacent two procedures, but since before many technical problems can't solve, work alone always.On the one hand, the turnover that the semi-finished product of mediating after processing are transferred in the extruding and granulating equipment has reduced production efficiency.On the other hand, also be prior one side, some material (mixed material) after the kneader discharging circular flow physics, chemical property change outside the expection has taken place, influenced normally carrying out of later stage extruding pelletization, even can't continue the operation in later stage.
Summary of the invention
Technical problem to be solved by this invention is, overcome the defective of above-mentioned existing procucts, and a kind of kneading extruding and granulating equipment is provided, and kneader device, extrusion equipment and Granulation Equipments are designed to the production line integral body of an organic contact, improve granulation quality and production efficiency.
The present invention has adopted following technical scheme.
A kind of kneading extruding and granulating equipment, comprise kneading extruder and granulate equipment, kneading extruder comprises the kneading paddle that two axial lines is parallel to each other, it is characterized in that: extrusion screw rod is installed on two and mediates under the paddle centre, and the axis of the axis of kneading paddle and extrusion screw rod is parallel to each other;
Be connected with distributing valve with first discharging opening and second discharging opening at the discharge end of kneading extruder, wherein second discharging opening is connected with granulate equipment.
Described granulate equipment is the pelleter that has water cooling system, and pelleter comprises head, and the cutting knife that is fixed on the material discharging mould on the head and is fixed in the head lower end, cutting knife are installed on the head central shaft;
Below head, be provided with the pelletizing chamber, this upper surface, pelletizing chamber sealing, the lower end has grain export; The top of pelletizing chamber, promptly a section around cutting knife is the sandwich cylinder shape, the barrel interlayer of annular has the end face of two sealings up and down and has water inlet pipe, offer several water spray slits therein on the internal layer barrel evenly distributedly, these water spray slits all vertically are provided with along the internal layer barrel, promptly have the trend with the head central axes, they are in same height and position.
Side at each water spray slit is provided with a deflector, the inner of this deflector and internal layer barrel one or fix, and the mezzanine space between deflector and the internal layer barrel is an intake tunnel, the inwall of the center line of this intake tunnel and internal layer barrel is tangent; The center circle of the center line of water inlet pipe and barrel interlayer is tangent.
Described granulate equipment can also be pelletizing, cooling split equipment, and it comprises the extruder that is connected with second discharging opening successively, extrudes excellent cooling bath and pellet device.
Good effect of the present invention is:
(1), mediate and be extruded as an organic whole, avoided mixed material that the outer physics of expection, chemical property change take place circular flow after the kneader discharging, influence normally carrying out of later stage extruding pelletization, even can't continue the working-procedure problem in later stage.And granulation production efficiency and end product quality have been improved.
(2), directly to clash into the problem that the inwall of internal layer barrel brings be the bonding barrel of particle to the higher particle of temperature.Among the present invention, the granulating mechanism water cooling system has unique construction.The water that enters from water inlet pipe has certain pressure, through the deflector water conservancy diversion, spray into the pelletizing chamber at a high speed from the water spray slit, and form the annular water band of rotation at a high speed between cutting knife and internal layer barrel, this direction of rotation of rotating the water band at a high speed is opposite with the direction of rotation of cutting knife.The particle that breaks away from cutting knife has changed movement locus under the effect of water band, avoided contacting and adhesion too early with the internal layer barrel.Simultaneously, the particle that breaks away from cutting knife had longer moving line before discharging from grain export, and cooling effect is better.
(3), material at first enters distributing valve after being extruded, contain the material (being commonly called as dead material) of mediating bad composition mediated repeatedly, mixing, reach to mediate and just be admitted to the pelletizing head after requiring.Guaranteed the abundant kneading of material.
(4), its whole structure is simple, compact conformation, floor space is little, and is easy to operate.
