PULP INSPECTOR — Dirt & Shives Module
The PULP INSPECTOR DIRT & SHIVES MODULE performs continuous analysis of the entire pulp flow going through a measuring cell, counting all impurities typically found in pulps as dirt dots and shives.
Applications and Purpose
The module is designed for the on-line monitoring of pulp contamination, ensuring quality control and process stability.
- Core Function: Analyzes the whole pulp flowing through a measuring cell.
- Contaminants Counted: All impurities typically found in pulps as dirt dots and shives.
- Expertise: Based on the well-known Simpatic dirt counter, leveraging 15 years of experience in on-line dirt counting for deinking, recycling pulps, and paper manufacturing.
- Sampler: Uses the same sampler as the basic Pulp Inspector module.
Key Features & Highlights (Analysis & Classification)
The system uses the Simpatic software for on-the-fly analysis and identification of various contaminants.
- High-Speed Imaging: The system takes up to 30 images per second with a digital IP camera.
- Resolution: Adjustable resolution from $50 \text{ µm}$ to $100 \text{ µm}$.
- On-the-fly Analysis (Simpatic Software): Detects all contrasted contaminants in the pulp flow, such as:
- Black contrasted dirt.
- White contrasted elements.
- Shives discriminated by shape ratio detection.
- Classification: All elements are classified by size classes & surface.
- Impurity Visualization (Software Markers):
- Shives or unbleached fiber (blue square).
- Small ink, carbon, or dirt specs (red square).
- Larger dirt or ink particles (identified).
XTREND INTERFACE (Graphic Interface)
Techpap has developed a specialized graphic interface for results viewing and management.
- Features:
- Multi-users (through TCP/IP).
- Multi-sensor capability.
- Each workspace is configurable with:
- Trend curves
- Histogram
- Sectors
