The specific embodiment
Below in conjunction with accompanying drawing the utility model is made detailed description.
Continuous rotary pelleter described in the utility model; comprise cylindrical shape rotating cylinder 1; supporting plate 2; by supporting the transmission device that drive 10 and support component 7 constitute; cutter; wherein the inwall of rotating cylinder 1 is provided with the continous way supporting plate 2 with the cylindrical shell axially parallel; cutter is arranged on the center of rotating cylinder 1 inside; independent rotation; cutter supporter 3 is discoid; be arranged on the two ends of back shaft 4; along the back shaft direction cutting knife 6 is set between two cutter supporter; cutting knife is thin-line-shaped; cutting knife is provided with a circle or a multi-turn in the diametric(al) of cutter supporter, and several are set in a circumferential direction.The support bar 5 of many group vertical support axles is set on the back shaft between two cutter supporter, every group is provided with a plurality of a plurality of support bars 5 that radially are evenly distributed, each support bar 5 one end links to each other with back shaft 4, and support bar 5 links to each other with cutting knife 6, is used for fixing cutting knife 6, the method of fixed cutting tool 6 has multiple, preferably adopt and on support bar 5, open small sircle hole 11, cutting knife is passed through small sircle hole 11, the so both radial position of fixed cutting tool 6, have certain elasticity again, prolong the service life of cutting knife.
Pretreated strip-shaped materials enters in the rotating cylinder 1 by charging aperture 8, rotation along with rotating cylinder, material is lifted by supporting plate 2, when supporting plate 2 is lifted to certain altitude along with the rotation of cylindrical shell, because the variation of supporting plate angle, material is owing to the free-falling of gravity reason, bump against with the cutting knife that rotates, strip-shaped materials is in the most weak position fracture of mechanical strength, and the strip-shaped materials after the collision can fall on the revolving drum 1, hold up by supporting plate 2 once more and continue to rotate, continue collision with cutting knife 6 with rotating cylinder.Because rotating cylinder 1 has certain gradient, when strip-shaped materials turned to rotating cylinder discharging opening 9, granularity just in time reached requirement.
Continuous rotary pelleter of the present utility model has been owing to used continuous cutting knife pattern, thereby shortened the cylindrical shell length of revolving drum; Because what use in disconnected bar process is the fracture naturally of depending on collision to produce, only be the difference that relies on the mechanical strength of bar, rather than pure mechanicals efforts ruptures by force, thus significantly reduced the generation of dust and fragment, thus improved the quality of pelletizing.
