Abstract

A parallel twin-screw extrusion granulator comprises a parallel twin-screw extruder (1). A first screw (3) and a second screw (4) are mounted in a screw barrel (2) of the parallel twin-screw extruder (1), an extrusion opening (21) is formed in the screw barrel (2), the head of the first screw (3) and the head of the second screw (4) are positioned at the extrusion opening (21), and scattering blocks (5) are fixed to both the head of the first screw (3) and the head of the second screw (4). The parallel twin-screw extrusion granulator has the advantages that the scattering blocks are arranged at the twin-screw extrusion opening, so that extruded particles can be scattered into small particles, the small particles are uniform, and the extrusion speed and the cyclone cooling speed can be increased.

Description

A kind of parallel double-screw extruding granulator
Technical field:
The utility model relates to the comminutor technical field, more specifically to a kind of parallel double-screw extruding granulator.
Background technology:
CN201702872U, the patent No.: 201020178589.1 disclose a kind of plasticizing Granulation Equipments for high-share plant fibers filled polyolefin wood plastic composite, and in this Granulation Equipments an equipment chief component being arranged is parallel double-screw extruder.Its weak point is: 1, its parallel double-screw extruder is provided with open slicing device at twin-screw extrusion place, and is inconvenient but this slicing device blade is installed, and fracture easily.Be in the condition of high temperature when 2, Wood-plastic material plastifies granulation in parallel double-screw extruder, very soft, slicing device can not all be moulded wood the particle chopping sometimes, and effect is limited.
The utility model content:
The purpose of this utility model is exactly the deficiency at prior art; and a kind of parallel double-screw extruding granulator is provided, it is provided with the dispersion piece at twin-screw extrusion place, make the particle of extruding be broken into granule; uniform particles, thus can improve extruded velocity and accelerate the whirlwind cooling velocity.
Technology solution of the present utility model is as follows:
A kind of parallel double-screw extruding granulator; comprise parallel double-screw extruder; first screw rod and second screw rod are installed in the barrel of parallel double-screw extruder; form extrusion on the barrel; the head of first screw rod and second screw rod is positioned at the extrusion place, and the head of first screw rod and second screw rod all fixedly has the dispersion piece.
Described dispersion piece is several teeth, and several teeth annular array respectively are distributed in the head of first screw rod and second screw rod.
Described dispersion piece is toothed disc, two toothed discs are distinguished sleeve at the head of first screw rod and second screw rod, two blocks are screwed onto on first screw rod and second screw rod respectively and are pressing two toothed discs respectively, and the bottom of two toothed discs is close to respectively on the first screw flight external member and the second screw flight external member.
The beneficial effects of the utility model are:
It is provided with the dispersion piece at twin-screw extrusion place, makes the particle of extruding be broken into granule, uniform particles, thus can improve extruded velocity and accelerate the whirlwind cooling velocity.
Description of drawings:
Fig. 1 is the structural representation of embodiment 1;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the structural representation of embodiment 2.
Among the figure: 1, parallel double-screw extruder; 2, barrel; 3, first screw rod; 4, second screw rod; 5, disperse piece; 21, extrusion; 6, block; 31, the first screw flight external member; 41, the second screw flight external member.
The specific embodiment:
Embodiment 1: see shown in Fig. 1,2; a kind of parallel double-screw extruding granulator; comprise parallel double-screw extruder 1; first screw rod 3 and second screw rod 4 are installed in the barrel 2 of parallel double-screw extruder 1; form extrusion 21 on the barrel 2; the head of first screw rod 3 and second screw rod 4 is positioned at extrusion 21 places, and the head of first screw rod 3 and second screw rod 4 all fixedly has the piece 5 of dispersion.
Described dispersion piece 5 is several teeth, and several teeth annular array respectively are distributed in the head of first screw rod 3 and second screw rod 4.
Embodiment 2, see shown in Figure 3, described dispersion piece 5 is toothed disc, two toothed discs are distinguished sleeve at the head of first screw rod 3 and second screw rod 4, two blocks 6 are screwed onto on first screw rod 3 and second screw rod 4 respectively and are pressing two toothed discs, the bottom of two toothed discs to be close to respectively on the first screw flight external member 31 and the second screw flight external member 41 respectively.All the other are with embodiment 1.
Operation principle: the material of high temperature is extruded by just forming smaller particles after disperseing piece 5 to break up when extruding.
