Disc Heat Dispersing System

Product Description

The Heat Dispersing System is essential in the preparation of waste paper pulp, utilizing a combination of mechanical and thermal dispersion methods. This system efficiently eliminates impurities such as stickies, grease, paraffin, plastic, rubber, and ink particles, significantly enhancing the quality and performance of the final paper product. Comprising components like slurry thickening equipment, a plug screw, crushing screw, preheater, and disc heat dispersing machine, the Heat Dispersing System is designed for optimal efficiency. It features PLC automatic control, ensuring high precision in operation.

Core Role in Waste Paper Pulp Processing

In modern paper recycling facilities, managing complex contaminants is a primary challenge. The Disc Heat Dispersing System serves as the central processing unit for upgrading recycled fibers. By integrating both thermal and mechanical dispersion techniques, it addresses impurities that traditional screening and cleaning stages cannot completely remove. The thermal phase softens thermoplastic contaminants, while the subsequent mechanical action disperses them into microscopic particles. This dual-action approach ensures that the recycled pulp meets the strict visual and structural requirements necessary for producing high-grade packaging paper, corrugated fluting, and cultural papers.

Comprehensive Impurity Elimination

The presence of residual contaminants in waste paper pulp can lead to severe operational issues, including web breaks on the paper machine and visual defects in the finished product. This system is specifically engineered to target and neutralize a wide spectrum of stubborn impurities:

• Stickies and Adhesives: Prevents the agglomeration of glue materials that typically foul machine wires, felts, and drying cylinders.

• Grease and Paraffin: Effectively breaks down lipid-based and waxy substances, preventing dark spots and improving the surface uniformity of the paper.

• Plastic and Rubber: Disperses synthetic fragments that would otherwise compromise the tensile strength and structural integrity of the paper sheet.

• Ink Particles: Detaches and disperses residual ink compounds, which is a critical step for enhancing the brightness, whiteness, and overall cleanliness of the final pulp.

System Composition and Processing Workflow

The high efficiency of the Heat Dispersing System relies on the seamless coordination of its core components. Each piece of equipment plays a distinct role in continuously preparing and processing the pulp:

• Slurry Thickening Equipment: Increases the consistency of the incoming waste paper pulp to the optimal level required for effective heat treatment and mechanical friction.

• Plug Screw: Compresses the thickened pulp to form a dense, continuous material plug. This crucial step squeezes out excess water and creates a pressure seal that prevents steam from escaping the heating chamber.

• Crushing Screw: Receives the highly compressed pulp plug and breaks it down into smaller, uniform pieces. This maximizes the exposed surface area of the fibers, allowing for rapid and even steam penetration.

• Preheater: Utilizes controlled steam injection to elevate the temperature of the shredded pulp. This thermal conditioning phase softens the stickies, hot melts, and other impurities, preparing them for dispersion.

• Disc Heat Dispersing Machine: The primary processing unit where the heated pulp is subjected to intense mechanical friction. This action thoroughly disperses the softened impurities into harmless, invisible particles while preserving essential fiber strength.

High-Precision PLC Automatic Control

To guarantee consistent performance and operational stability, the entire system is governed by an advanced Programmable Logic Controller (PLC) automatic control system. This intelligent automation platform continuously monitors and regulates critical process variables, including pulp feed rates, steam pressure, heating temperatures, and processing consistency. By utilizing PLC automatic control, the system ensures high precision in operation, minimizes the need for manual adjustments, reduces the risk of human error, and maintains a continuous, stable production flow. This level of automation is essential for modern pulping facilities aiming to achieve uniform pulp quality while optimizing overall operational efficiency.

High-Efficiency Dispersion for Cost-Effective Operation: The Disc Heat Dispersing System utilizes an advanced belt spiral feeding mechanism designed to ensure stable and continuous material flow. This innovative feeding approach allows for highly effective high-concentration dispersion while significantly reducing overall power consumption. By optimizing the mechanical action applied to the pulp, the system ensures minimal fiber damage during the dispersion process. Preserving the natural length and integrity of the fibers is crucial for maintaining the structural quality of the final paper product. For paper mill operators, this technical advantage directly translates into lower energy bills and higher production yield without compromising the essential characteristics of the raw material.

Versatile Applications in Waste Paper Processing: Engineered for maximum adaptability across different production lines, this equipment is highly suitable for processing a wide variety of waste paper raw materials. It excels particularly in the high-concentration heat dispersion of deinked pulps (DIP) and recycled cardboard manufacturing. Whether dealing with mixed office waste, old corrugated containers (OCC), or heavily inked secondary fibers, the system effectively tackles challenging contaminants such as hot melts, stickies, waxes, and stubborn ink particles. This versatility makes it an indispensable asset for modern paper recycling facilities aiming to produce clean, high-grade paper from diverse and fluctuating waste streams.

Durable Components for Reduced Maintenance Downtime: The core operational components of the system are built to withstand continuous use in harsh industrial environments. Specifically, the grinding disc is constructed from premium-grade hard alloy materials. This robust construction offers exceptional wear resistance and superior corrosion resistance, even when processing abrasive waste paper pulps containing residual chemical agents. The high durability of the grinding disc guarantees a significantly longer operational life compared to standard alternatives. By minimizing the frequency of component replacements, paper manufacturers can drastically reduce maintenance downtime, lower spare parts inventory costs, and ensure stable, uninterrupted production cycles.

Enhanced Pulp Quality and Superior Physical Strength: A critical advantage of this dispersing system is its ability to fundamentally improve the quality of the processed pulp. Featuring a larger refining area combined with a precisely engineered, innovative tooth shape, the grinding disc maximizes the efficiency of thermal dispersion. This unique design facilitates optimal fiber-to-fiber friction and controlled fiber splitting (fibrillation) without aggressively cutting the fibers. As a result, the treatment significantly enhances the binding capacity of the fibers, which directly translates to improved physical strength properties of the finished paper. Operators will notice a marked increase in critical metrics such as tearing resistance and tensile strength, ensuring a premium end product that meets strict industry standards.

User-Friendly Design for Streamlined Mill Operations: Beyond its processing capabilities, the system features a streamlined, simple structure designed with the daily operational needs of mill personnel in mind. This thoughtful engineering allows for highly convenient maintenance, easy inspection, and quick access to internal components when servicing is required. Furthermore, the equipment is optimized to operate with exceptionally low noise levels, creating a safer and more comfortable working environment on the factory floor. By combining high performance with ease of use and reduced acoustic emissions, this system stands out as a reliable solution for upgrading modern pulp and paper production facilities, ensuring both operational efficiency and workplace safety.
