Hermetically Sealed Explosion-Proof En-Masse Chain Conveyor

Hermetically Sealed Explosion-Proof En-Masse Chain Conveyor

—— The Ultimate Solution for Safe Conveying of Flammable & Explosive Powders

Product Overview

The hermetically sealed explosion-proof en-masse chain conveyor is a high-risk powder conveying system specially designed for industries such as chemical engineering, pharmaceutical, grain processing, and new energy. It is suitable for fully enclosed conveying of flammable and explosive materials including metal dust, coal powder, plastic granules, and pharmaceutical raw materials. The system integrates multiple safety technologies such as inert gas protection, static elimination, and spark detection, complying with international explosion-proof standards including ATEX, NFPA, and GB. It completely eliminates risks of explosion, oxidation, and contamination during powder conveying, achieving zero leakage and zero sparks in the conveying process and ensuring safe production in high-risk industries.

Core Advantages

✅ Safety-Oriented Explosion-Proof Design

▸ Explosion-proof triple-linkage system:

▸ Anti-static chain (surface resistance ＜10⁶Ω)

▸ Flameproof motor (Ex dⅡBT4)

▸ Nitrogen inerting interface (customizable for oxygen content ＜8%)

▸ Spark-free structure: Copper alloy scrapers + ceramic bearings, eliminating the risk of mechanical friction sparks.

✅ Military-Grade Hermetic Performance

▸ Fully welded stainless steel trough, with weld hermeticity tested to 10⁻⁶Pa·m³/s (helium mass spectrometry leak detection standard).

▸ Double-lip pneumatic sealed door equipped with pressure sensor, which triggers automatic leakage alarm and links to the air supply system.

✅ Intelligent Safety Monitoring

▸ Five explosion parameter monitoring: Real-time detection of temperature, pressure, dust concentration, oxygen content, and electrostatic potential, with data connected to the factory DCS system.

▸ Emergency explosion venting device: Bursting disc + flameless pressure relief valve (NFPA 68 standard), with explosion venting efficiency ＞95%.

✅ Adaptability to High-Risk Media

▸ Anti-corrosion & anti-adhesion version: PTFE lining or Hastelloy material, suitable for corrosive media such as hydrofluoric acid and strong alkali.

▸ Self-cleaning design: Screw scrapers + vibration dust cleaning system, solving the problem of residual high-viscosity materials.
