Described body is the axial subdivision structure, comprises urceolus and inner core, forms to docking by two cage modle half housing shaft, and the body inner face is provided with fluting four kinds of different cage bars of size, and minutes four sections along body inner core surface along the circumference setting, forms the body internal diameter; Be provided with alternately up and down 8 shear plates at the body interior profile, be used for the restriction material and rotate with screw rod; Body is with 5 joint compression swivel nut sealings of screw shaft;
Described figure automatic control system is comprised of temperature-sensing element and pressure sensor and data handling system;
Described pressure regulation body is electronic and manual combination, and operating part adopts two worm gears, gear, worm drive chain structure;
Described reductor is the two-stage gear drive, and its output shaft rear portion arranges the axial thrust spherical bearing, and adopts mandatory centralized lubrication cooling device; The two-stage gear of described reductor is respectively: the hard flank of tooth roll flute of first order helical gear; The hard flank of tooth roll flute of second level assembled herringbone bear
The axle external diameter that coordinates with the swivel nut internal diameter in described assembled screw shaft adopts 3 sections hierarchic structures;
The structure in its exit of described pressure regulation body is taper, and less than spiral external diameter.
Operation principle of the present utility model is: according to the Screw Extrusion principle, adopt the not isometrical screw-rod structure that does not wait dark displacement dextrorotation pulling force form, be that moisture rubber grain is entered by charging aperture continuously, the spiral part of swivel nut is on one side to the conveying of rubber grain, on one side become warp by displacement the spiral swivel nut compress.
During the utility model work: main motor drives two-stage gear transmission reducing device through snakelike shaft coupling, drives screw rod through the moving folder of output shaft output-parallel coupling and rotates with 130r/min dextrorotation; The reinforced swivel nut of first segment on screw shaft pushes body with micelle, and other 5 joint swivel nut constantly dewaters sizing material by reducing gradually pitch and change the screw slot footpath, forms viscosity flow.The shear plate restriction viscosity flow circumference rotational flow that arranges in body, moisture in, viscosity flow more and more less in the space that the reducing swivel nut forms is extruded basically after the cage interspace flows out body, have in the setting of screw shaft end on three sections swivel nuts of otch, viscosity flow is overturn and cuts, remaining moisture is presented on the material surface.When viscosity flow arrival pressure regulation body exit, because the exit structure is taper, and less than spiral external diameter, form resistance pressure, moisture gasifies under the pressure and temperature effect, makes rubber viscosity flow high speed explosion ejection final dewatering, and the butt rubber after dehydration forms micelle under the cutting knife effect.
Advantage of the present utility model: digital technology control, scientific and reasonable for structure, efficient is high, and is corrosion-resistant, easy to maintenance.Single machine yield can improve approximately 20%, energy efficient 15% left and right, and economic benefit is very remarkable.
