Abstract

The utility model relates to a co-rotating conical twin-screw PP granulator which comprises a granulating device 1, conical screws 2, an air outlet 3, a cylinder 4, a heating ring 5, a feeding device 6, a distribution box 7, a reduction gearbox 8, a coupling 9, a driving motor 10 and a rack 11 and is characterized in that the two conical screws rotate in the cylinder in the same direction; and the effective length-diameter ratio of each screw is 24-70:1. The co-rotating conical twin-screw PP granulator has the advantages of excellent plasticizing performance, high yield and low energy consumption, and is novel granulation equipment applicable to PP granulation production.

Description

Conical double-screw PP comminutor in the same way
Technical field
The utility model relates to a kind of PP Granulation Equipments, particularly conical double-screw PP comminutor in the same way.
Background technology
The comminutor that carries out PP (polypropylene) granulation production at present mainly contains parallel double-screw comminutor and single screw pelletizer.Single screw pelletizer 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 single screw pelletizer screw rod has been subjected to certain influence, so influenced the soffening of raw material.Simultaneously because parallel double-screw comminutor screw speed is very high at present, so there are shortcomings such as energy consumption height, gear-box be fragile.
Summary of the invention
Have the energy consumption height in order to solve present parallel double-screw comminutor and single screw pelletizer, yield poorly, problem such as plasticizing capacity difference, the utility model provides the PP of conical double-screw in the same way that a kind of plasticizing capacity is good, output is high, energy consumption is low comminutor.
The PP of conical double-screw in the same way comminutor of the present utility model comprises pellet device, conical screw, exhaust outlet, machine barrel, heating collar, drawing-in device, distributor box, speed reducing transmission case, shaft coupling, drive motors, frame; it is characterized in that the equidirectional rotation in machine barrel of two conical screws; the effective L D ratio of every screw rod is 24～70: 1; be provided with idler gear above or below driving gear that is connected with two conical screws in the distributor box and the driven gear, the conical screw top diameter is between 20～300mm.
Therefore the PP of conical double-screw in the same way comminutor of the present utility model has possessed advantages such as the plasticizing mixing behavior is good, screw speed is high, draw ratio is big owing to possessed the homodromal screw-rod structure of parallel parallel dual-screw comminutor screw rod.During work, drive motors is connected to speed reducing transmission case by shaft coupling, speed reducing transmission case 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 make the two conical screws equidirectional rotation in machine barrel that is connected with driven gear with driving gear, the PP raw materials melt that will be carried by drawing-in device, mixing, plasticizing, exhaust are after pellet device carries out pelletizing.
The beneficial effects of the utility model are:
Because the PP of conical double-screw in the same way comminutor of the present utility model has possessed whole advantages of conical double-screw comminutor and parallel parallel dual-screw comminutor simultaneously; have that the power of extruding is big, energy consumption is low, good, the advantages such as screw speed is high, draw ratio is big, output height of plasticizing mixing behavior, be a kind of high yield, low energy consumption, novel PP Granulation Equipments cheaply.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is the equidirectional rotary conic screw-rod structure schematic diagram of the utility model embodiment.
