The effective diameter ratio of the two conical screw rods is increased, so that the plasticizing performance of the equipment is greatly improved; as calcium carbonate at high proportion can be added, the yield is greatly increased and the energy consumption is reduced; therefore, the granulating equipment is particularly a novel plastic granulating equipment suitable for production and granulation of such plastics as PVC (polyvinyl chloride), PP (polypropylene), PE (polyethylene), TPR (thermo plastic rubber), TPE (thermoplastic elastomer), ABS (acrylonitrile butadiene styrene), TPU (thermoplastic polyurethane), etc.
Description
Technical field
The utility model relates to a kind of plastic granulator, particularly a kind of super large draw ratio twin-screw Granulation Equipments.
Background technology
The dual-screw pelletizer that carries out plastic granulating production at present mainly contains parallel double-screw comminutor and conical double-screw comminutor.The conical double-screw comminutor is because have the big advantage of the power of extruding, so be widely used in the plastic granulating production.Because be subject to processing the influence of technology, the effective L D ratio of conical double-screw comminutor screw rod has been subjected to certain influence, its effective L D ratio is all less than 22: 1, so influenced the soffening of raw material at present.Simultaneously because the draw ratio of conical double-screw comminutor is smaller at present; so the tapering of screw rod is bigger; caused the rotating speed of screw rod can not be too high; otherwise can cause screw rod to be twisted off; therefore reduced yield of unit time; increased the energy consumption of specific yield, thus at present the conical double-screw comminutor exist plasticizing capacity poor, yield poorly, shortcoming such as energy consumption height.
Summary of the invention
For solve present conical double-screw comminutor exist plasticizing capacity poor, yield poorly, problem such as energy consumption height, the utility model provides a kind of big L/D ratio, output height, super large draw ratio twin-screw Granulation Equipments that energy consumption is low.
The utility model is achieved through the following technical solutions:
Super large draw ratio twin-screw Granulation Equipments of the present utility model comprises drive motors, shaft coupling, reduction box, distributor box, drawing-in device, heater, machine barrel, exhaust apparatus, two conical screws, pellet device, support, described two conical screws are rotation or incorgruous rotation in the same way in machine barrel, and the effective L D ratio of every screw rod is 25～95: 1.
During the utility model work, drive motors is connected to reduction box by shaft coupling, reduction box connects the driving gear in the distributor box, drive idler gear by the driving gear in the distributor box, idler gear drives driven gear again, thereby makes the two conical screws rotation in the same way in machine barrel that is connected with driven gear with driving gear; Or by the drive of the driving gear in distributor box driven gear, thereby make the two conical screws incorgruous inside rotation or incorgruous in machine barrel that is connected with driven gear with driving gear to inner rotary.Two conical screws the raw materials melt that will be carried by drawing-in device, mixing, plasticizing, exhaust, are extruded, after pellet device carries out pelletizing in machine barrel in the same way or during incorgruous rotation.
The beneficial effects of the utility model are:
1, the effective L D ratio with every conical screw is increased to 25～95: after 1, increase the banburying performance of fusion time and screw rod, improved the plasticizing capacity of machine greatly, thereby guaranteed the plasticizing quality of product, make simultaneously and can add a high proportion of calcium carbonate, reduced production cost.
2, the effective L D ratio with every conical screw is increased to 25～95: after 1; when two conical screws in machine barrel in the same way or during incorgruous rotation; can carry to 150rmp the screw speed of conical double-screw comminutor (existing be no more than 40rmp) screw speed is the highest; therefore output is improved greatly, greatly reduce the energy consumption of specific yield simultaneously.
In sum, the utlity model has that plasticizing capacity is good, output is high, low power consumption and other advantages, is the novel Granulation Equipments of various plastics-production such as a kind of PVC of being applicable to, PP, PE, TPR, TPE, ABS, TPU.
