High capacity pulping node

High-capacity pulping node comprises a pulper LCV-65 working in a continuous mode. Spinning trash is removed from the LCV-65 during the operation by means of trash tail ragger SN-13 and trash tail cutter DZS-65. Other devices cleaning the pulper during the operation are two periodic separators PSN-40.

Design

High-capacity pulping node comprises a pulper LCV-65 working in a continuous mode. Spinning trash is removed from the LCV-65 during the operation by means of trash tail ragger SN-13 and trash tail cutter DZS-65. Other devices cleaning the pulper during the operation are two periodic separators PSN-40. Rejects leave the periodic separators towards a dewatering drum OBN-20 where they are flushed and dewatered. The dewatering drum OBN-20 together with a self-cleaning trash rack placed in a pit below the drum enable draining rejects towards a reject dewatering press OLV-600.

The final node layout depends on a required performance of the entire line (for example at a high raw material throughput and at the mentioned line performance 1 or 2 separators PSN-40 and 1 or 2 cleaners VS-50 are supposed).
