NON-METALIC CHAIN ​​FLIGHT CHAIN FLIGHT SLUDGE COLLECTOR

Installed in the sedimentation basin of a sewage and wastewater treatment plant, it is a high-efficiency water treatment core facility that simultaneously transfers the sludge settled at the bottom to the front hopper and the scum floating to the top to the scum collector through two rows of chains and flights rotating in an endless orbit.

  • Application of new material ‘PPA’ perfectly optimized for underwater environment We have overcome the fatal limitations of nylon, which loses up to 50% in strength when it absorbs moisture, and acetal, which stretches easily.
    PPA (polyphthalamide), a top-class high-performance engineering plastic, is adopted for the main chain, so no loss of strength or deformation occurs even when operated 24 hours a day in water or exposed to high levels of hydrogen sulfide gas in sewage.

  • Double lifespan, innovative ‘DL (Double Life) sprocket’ A DL-type sprocket is used, which guarantees twice the lifespan of regular products.
    Chain breakaway accidents are completely prevented through the SAVE RIM structure, which prevents abnormal wear of the tooth teeth.
    The chain pin is designed with a steel-reinforced structure and a T-head locking method to prevent rotation and can easily withstand up to a shear force of 4,800 kgf.

  • Zero disadvantages, all-in-one ‘PINTLE CHAIN’ This is an international standard (ASME) standard product that fundamentally solves the roller wear and damage problems of loop chains that were popular in the past.
    The chain pin is designed with a steel-reinforced structure and a T-head locking method to prevent rotation and can easily withstand up to a shear force of 4,800 kgf.

Steel Reinforced Plastics (SRP):
Injection of thermoplastic polyamide inside stainless steel pipe.
Perfect protection against fine sand/sludge wear.
T-Head Structure:
Ultra-high strength design that withstands the maximum shear force of 4,800kgf of the chain as the pin does not rotate.

(2.5 times mechanical efficiency)
conclusion: By reducing the number of parts and preventing each part from deteriorating in efficiency, the pintle chain exhibits approximately 2.5 times higher mechanical efficiency than the loop chain under actual use conditions.

Application areas: Applicable to all-weather environments such as water purification plants, sewage and wastewater treatment plants, as well as petrochemical plants (API) and seawater desalination facilities (DAF) that require high durability.

Durability & Safety

2 Overwhelming durability and safety system

Passed extreme durability test

Through in-house testing, it completely passed 130,000 cycles (cycles) of operation under harsh conditions with a load of 2,000 kg and a speed of 6.0 m/min, and achieved the world's highest breaking strength of 5,000 kg.f and a maximum tensile load of 50,395 N certified by the Korea Testing & Research Institute (KTR).

Intelligent double safety device (meander and break detection)

If there is a problem or breakage in the chain, or if the flight is twisted (meandering), the proximity sensor immediately detects this, stops the operation of the facility, and sends a warning to the central monitoring panel to prevent major accidents and equipment damage.

Maintenance & Eco-friendly

3 Groundbreaking maintenance and environmental friendliness

Reduce compatibility and maintenance costs

It is 100% compliant with the international ANSI standard and is fully compatible with existing third-party equipment. When the sprocket wears out, there is no need to replace the entire sprocket, but only the ‘adapter’ of the hub can be replaced, drastically reducing maintenance costs by 1/10.

Easy on-site assembly

The number of parts has been reduced to 1/2 compared to existing products, allowing anyone to quickly and easily disassemble and assemble in the field with just a screwdriver.

100% recycled eco-friendly material

Unlike FRP loop chains, it is made of 100% recyclable thermoplastic eco-friendly material that does not generate environmental pollutants during production and disposal.
