Abstract: 1,050,668. Washing rubber; pelletizing rubber. CASEY CHEW KAM CHONG. Oct. 20, 1965 [July 31, 1964], No. 30343/64. Headings B2A and B2H. An apparatus for washing foreign material from rubber or like material comprises a cylindrical body 1 with an inlet end for receiving washing water and feed material and a rubber discharge end. Drain channels 3, for water and entrained foreign material, are disposed at the inner surface of the body 1 and run from its inlet to its discharge end. Feed means are provided for directing the feed material to the inlet end from which it is conveyed towards the discharge end by means of a drivable screw member 4. Outlets 12 from the drain channels are arranged so that substantially only the water and foreign material are discharged therethrough, the washed rubber being discharged at the discharge end. As shown, the channels 3 are formed between steel strips 2 of trapezoidal cross-section and are covered at their lower ends by an annular member 11 secured to the radially inner faces of the strips 2. The covered part of each channel communicate with an opening 12 in the cylindrical body 1 for the discharge of water and entrained foreign material. A flow control member 14 defines with the screw member 4 a variable annular space 13 for the egress of cleaned rubber. A funnel-shaped member 9 is provided at the inlet end for feeding the material on to which washing water is sprayed from nozzles in an annular distributor pipe 10. Alternatively, the feed material is introduced through a chute disposed below the member 9, Fig. 4 (not shown). The screw member 4 has a square thread with serrations 7 on its lower flank for gripping the rubber pieces causing them to be churned as they pass through the apparatus. Part of the thread at the inlet end protrudes further than the rest of the thread in order to sweep the rubber pieces into the inlet. This may also be done by short spokes extending radially outwardly from the thread at the inlet end. The rubber to be washed is cut by means of a hammer mill or a granulator before being fed to the apparatus, the pieces of rubber being sufficiently large not to become wedged in the channels 3. Castor oil may be added to the feed to assist in the easier egress of rubber from the discharge end of the apparatus. In another embodiment, Figs 5 to 9 (not shown), the cylindrical body 1 is horizontal and outlets 12 are circumferentially and longitudinally spaced in the body wall and discharge into a common drainage tank 16. Baffle plates 17 prevent water with entrained foreign material from higher outlets to flow back into an outlet below them. At the outlet end of the cylindrical body a 4- blade cutter 18 is attached to the end of the screw member 4 and cuts the rubber prior to its being forced through a multi-hole die plate 19 whereby the pelletized rubber is produced. Castor oil is added to the feed material to aid the forcing of the rubber through the die.
