Abstract

A device is disclosed for producing elastomer compounds for use in the production of rubbers. The device may include a mixing extruder with at least one mixing area, and at least one charging area for receiving an elastomer; and at least one dewatering area disposed downstream from the at least one charging area for receiving the elastomer.

Claims

exact text as granted — not AI-modified
1 . A device for manufacturing and elastomer mixture for manufacturing rubber, the device comprising:
 a mixing extruder with at least one mixing area;   at least one charging area for receiving an elastomer; and   at least one dewatering area disposed downstream from the at least one charging area for receiving the elastomer.   
   
   
       2 . The device according to  claim 1 , wherein the mixing extruder is a multi-screw extruder. 
   
   
       3 . The device according to  claim 2 , wherein the mixing extruder is a ring extruder. 
   
   
       4 . The device according to  claim 1 , further comprising at least one charging area for receiving reinforcing material. 
   
   
       5 . The device according to  claim 4 , further comprising at least one charging area for receiving additives and/or aids. 
   
   
       6 . The device according to  claim 5 , further comprising at least one area for degassing. 
   
   
       7 . The device according to  claim 6 , further comprising at least one charging area for receiving a vulcanizing agent. 
   
   
       8 . The device according to  claim 1 , further comprising an extraction pump and mold disposed downstream from the mixing extruder, and wherein the at least one charging area for receiving the elastomer is connected to a supply tank via a supply line, and the elastomer is introduced into the at least one charging area via a metering pump. 
   
   
       9 . The device according to  claim 4 , further comprising a weigh feeder in communication with the at least one charging area for receiving the reinforcing material. 
   
   
       10 . The device according to  claim 5 , further comprising a supply tank for softeners connected by a line with the at least one charging area for receiving the additives and/or aids. 
   
   
       11 . The device according to  claim 10 , further comprising a metering pump for introducing the softeners into the charging area for receiving the additives and/or aids, and further comprising a heat exchanger disposed downstream from the metering pump. 
   
   
       12 . The device according to  claim 6 , further comprising a line in communication with the at least one area for degassing, and a vacuum chamber in communication with the line. 
   
   
       13 . The device according to  claim 7 , further comprising a weigh feeder in communication with the at least one charging area for receiving the vulcanizing agent. 
   
   
       14 . The device according to  claim 1 , further comprising a plurality of dewatering areas distributed along the length of the mixing extruder. 
   
   
       15 . The device according to  claim 1 , further comprising a plurality of charging areas distributed along the length of the mixing extruder, and a plurality of dewatering areas distributed along the length of the mixing extruder, wherein the dewatering areas and the charging areas are distributed in alternate succession. 
   
   
       16 . The device according to  claim 1 , further comprising a lateral extruder in communication with the at least one dewatering area. 
   
   
       17 . The device according to  claim 15 , further comprising a lateral extruder in communication with each of the dewatering areas.
