The specific embodiment

As Fig. 1 and shown in Figure 2, first embodiment of the utility model dewater unit is applicable to remove and reclaims moisture in the plastics particle, this dewater unit comprises the pipe-line cell 2, of extending front and back and drive the driver element 3 that described plastics particle moves in pipe-line cell 2, and the scraper plate 5 of these pipe-line cell 2 rear ends is fixed in front and back with extending.

The feed zone 21, one that this pipe-line cell 2 has a horizontal-extending and is hollow tube-shape is installed on feed zone 21 upsides and is funnelform feed hopper 22, and extended and the converging transition 23, of caliber convergent is connected in this converging transition 23 rear ends and the straight length 24 that backward extends, at least onely be positioned on straight length 24 inner peripheral surfaces and fixedly be covered on the baffle plate 27 of straight length 24 rear ends with the friction member 25, that the plastics particle that moves produces rubbing action by the rear end level of this feed zone 21 backward, reaches a Storage water tank 26 that is arranged at this converging transition 23 and straight length 24 belows.

This feed zone 21, converging transition 23 and straight length 24 are coaxial directly to extending connection.This friction member 25 is in the mode of left hand helix and to extend spirally on the inner peripheral surface of straight length 24 with the groove pattern be that example explains in the present embodiment, the kenel of also available strip projection extends spirally on the inner peripheral surface of straight length 24 during actual enforcement, or extend on the inner peripheral surface of converging transition 23 and straight length 24, so practical range does not exceed with the pattern and the position of friction member 25.Have a plurality of spilled water holes 231,241 that run through inside and outside side face on the bottom surface of this converging transition 23 and straight length 24, this Storage water tank 26 is arranged at these spilled water hole 231,241 belows before and after being exactly with extending.Has a perforation 271 on this baffle plate 27.

This driver element 3 has a motor 31 that is arranged at these feed zone 21 front sides, and one drives rotation and axle by motor 31 and is loaded on screw rod 32 in this pipe-line cell 2.This screw rod 32 has bar body 321 in a feed zone 21 that is installed on this pipe-line cell 2, converging transition 23 and the straight length 24, with the mode of the right-handed helix spiral plate 322 on these bar body 321 outer peripheral faces with extending axially, and a plurality of extend axially between the pitch of this spiral plate 322 and be radially extend upright stripper plate 323.This bar body 321 extend backward and this baffle plate 27 that stretches through out on perforation 271, and bar body 321 outer peripheral faces and 27 on baffle plate have a ring-type spacing.

When this stripper plate 323 was fixed in these bar body 321 outer peripheral faces, the height of stripper plate 323 was slightly less than the height of this spiral plate 322, just between the inner peripheral surface of stripper plate 323 and straight length 24 was to keep a spacing.This stripper plate 323 is that rotating shaft along bar body 321 extends axially and is fixed in bar body 321 outer peripheral faces in the present embodiment, but during actual enforcement, stripper plate 323 can be as illustrated in fig. 3 keeps an acute angle with the axis of bar body 321, therefore implements not exceed with the kenel of stripper plate 323.

As shown in Figures 1 and 2, this scraper plate 5 is L-shaped tabular of summary, and straight length 24 rear end mouth of pipe lower edges are fixed in an end, and extend along the axis direction of straight length 24 backward the other end.

Whereby, when the plastic garbage that reclaims after rubbing and cleaning, pour in this feed zone 21 by feed hopper 22, these screw rod 32 rotations of these motor 31 rotating drive this moment, spiral plate 322 interlocks of this screw rod 32 drive described plastics particle when rotating and enter in the converging transition 23 backward, because the caliber of converging transition 23 is to extend and convergent backward, therefore when described plastics particle is promoted and by the extruding of the inner peripheral surface of converging transition 23 convergents, most moisture in the plastics particle is extruded and leaked to Storage water tank 26 backward by spilled water hole 231.

Then the plastics particle is promoted to enter in the straight length 24 and move backward by spiral plate 322, in the moving process, the plastics particle can be extruded plate 323 and keep out and make the particle mutual extrusion in the straight length 24 go out residual moisture, and be expelled to Storage water tank 26 by spilled water hole 241, plastics particle after the extrusion can be released to the rear end of straight length 24 by the row of the spacing between stripper plate 323 and straight length 24 inner peripheral surfaces, and continue to be promoted by screw rod 32 backward, when particle arrives the rear end of straight length 24, stopped by baffle plate 27 again, cause the moisture content of extruding out mutually once more between particle, just be expelled to outside the straight length 24 then from the spacing of 321 of baffle plate 27 and bar bodies.The plastics particle of discharging this moment normally is rectangular bulk and rotate synchronously with screw rod 32, this scraper plate 5 be fixed in mouth of pipe limit can in time the plastics particle that rotates be stirred disconnected, to make things convenient for follow-up processing.

In addition, owing to have depression and the hand of spiral friction member 25 opposite on the inner peripheral surface of straight length 24 with spiral plate 322 hands of spiral, when causing the plastics particle to be promoted backward and friction member 25 produce friction, and the frictional force direction is the direction of advancing in contrast to the plastics particle, so the plastics particle is subjected to the frictional force extruding on the one hand and releases to straight length 24 with remaining moisture extrusion and by spilled water hole 241, the plastics particle is subjected to high pressure and friction and produces heat includes moisture with raising temperature with water evaporates on the other hand, when causing the plastics particle to be discharged by the rear end of straight length 24, produce many steam, can utilize a hair-dryer 4 that steam is dried up and dispels, so that the moisture in the particle is got rid of fully.The plastics particle of getting rid of moisture fully can reclaim the raw material of making quality again, improves its economic worth, also can reduce subsequent treatment cost simultaneously.

As Fig. 4 and shown in Figure 5, the structure of the utility model dewater unit second embodiment and the structure of first embodiment are roughly the same, its difference is in and has a plurality of preceding abrasive sticks 272 that extend radially on the trailing flank of this baffle plate 27, and this dewater unit also comprises one and is installed on straight length 24 rear ends of this pipe-line cell 2 and cuts dish 6 with the mill that the screw rod of this driver element rotates synchronously.But mill is cut dish 6 and is had the dish body 61 that a drived unit 3 drives rotation, and a plurality of back abrasive stick 62 that places dish body 61 leading flanks and extend radially.

Whereby, when driver element 3 drive screws 32 rotate, drive mill synchronously and cut dish 6 rotations, when the plastics particle that is squeezed into piece in the straight length 24 of pipe-line cell 2 is discharged by the rear end of straight length 24, can drop or pinching in this

baffle plate

27 and 6 of cutting plates of mill, 272 relative motions of preceding abrasive stick on back abrasive stick 62 on the mill cutting plate 6 that rotates and the fixing baffle plate 27 are rotated with the plastics particle that will form blocks and to be smashed, to make things convenient for the processing of down-stream.Can adjust 6 positions that are loaded on the bar body 321 of mill cutting plate in addition, with the spacing of change mill cutting plate 6 with baffle plate 27, and then the size of smashing material is cut in control.

As shown in Figure 6, the structure of the utility model dewater unit the 3rd embodiment and the structure of first embodiment are roughly the same, it is that axial straight line extends on the inner peripheral surface of converging transition 23 and straight length 24 that its difference is in the friction member 25 of this pipe-line cell 2, cause the plastics particle and friction member 25 frictions that in pipe-line cell 2, move behind drived unit 3 spirals, stop the plastics particle with frictional force on the one hand, on the other hand with the frictional force friction plastics particle of heating, to quicken to remove the moisture that is embedded in particle.

Take a broad view of above-mentioned, the dewater unit that the utility model reclaims plastics utilizes the screw rod 32 of driver element 3 to promote to clean plastics particle later enters the internal diameter convergent by the feed zone 21 of pipe-line cell 2 converging transition 23 with as preliminary extrusion dehydration, particle enters straight length 24 back because the stopping of stripper plate 323 of driver element 3 and extrusion dehydration once more, the frictional force that produces with the friction member on straight length 24 inner peripheral surfaces 25 stops particle and makes particle produce high temperature at last, with the residual moisture evaporate to dryness, to improve plastics particle quality, handle in order to subsequent recovery, increase and reclaim economic interests, so very practical really and progressive.
