Abstract
The utility model relates to a novel double-screw hard PVC pelletizer including a pelleting device 1, a machine barrel 2, conical threaded rods 3, a heating ring 4, a feed device 5, a hopper 6, a distribution box 7, a gearing-down box 8, a coupler 9, a driving motor 10 and a frame 11. The pelletizer is characterized in that the two conical threaded rods rotate in the same direction in the machine barrel; the effective slenderness ratio of each threaded rod is 30-100:1, the compression ratio of each threaded rod is larger than 2:1. The novel double-screw hard PVC pelletizer has the advantages of good plasticizing capability, high yield, low energy consumption, etc., and is suitable for hard PVC production and pelleting.
Description
Technical field
The utility model relates to a kind of hard PVC Granulation Equipments, particularly a kind of novel twin-screw hard PVC comminutor.
Background technology
Carry out the hard PVC granulation at present and mainly adopt single screw pelletizer and 2 kinds of Granulation Equipments of taper incongruous double screw comminutor.But because single screw pelletizer output is very low, energy consumption is also bigger, therefore adopts taper incongruous double screw comminutor to carry out the hard PVC granulation at present mostly.Because be subject to processing the influence of technology, the effective L D ratio of taper incongruous double screw comminutor screw rod has been subjected to certain influence, so influenced the soffening of raw material.Simultaneously because the incorgruous rotation of taper incongruous double screw comminutor screw rod at present; so 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 taper incongruous double screw comminutor exist plasticizing capacity poor, yield poorly, shortcoming such as energy consumption height.
Summary of the invention
Have the energy consumption height in order to solve present taper incongruous double screw comminutor, yield poorly, problem such as plasticizing capacity difference, the utility model provides the novel twin-screw hard PVC comminutor that a kind of plasticizing capacity is good, output is high, energy consumption is low.
Novel twin-screw hard PVC comminutor of the present utility model comprises pellet device, machine barrel, conical screw, heating collar, drawing-in device, hopper, distributor box, speed reducing transmission case, shaft coupling, drive motors, frame; the equidirectional rotation in machine barrel of described two conical screws; the effective L D ratio of every screw rod is 30～100:1, and the compression ratio of screw rod is greater than 2:1.
Therefore novel twin-screw hard PVC 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 PVC raw materials melt that will carry by drawing-in device, plasticizing, mixing, extrude, after pellet device carries out pelletizing.
The beneficial effects of the utility model are:
Because novel twin-screw hard PVC 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.Can substitute existing hard PVC Granulation Equipments fully, be a kind of high yield, low energy consumption, low cost, novel hard PVC Granulation Equipments simple to operate.
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.
Accompanying drawing 3 is the distributor box gear structure schematic diagram of the utility model embodiment.
The specific embodiment
Shown in Fig. 1～3; the novel twin-screw hard PVC comminutor of present embodiment comprises pellet device 1, machine barrel 2, conical screw 3, heating collar 4, drawing-in device 5, hopper 6, distributor box 7, speed reducing transmission case 8, shaft coupling 9, drive motors 10,11, two conical screw 3-1 of frame and the equidirectional rotation of 3-2 in machine barrel 2.
The foregoing description and accompanying drawing are to further describe of the present utility model, but the claimed scope of the utility model is not limited to the scope described in the embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (2)
