The explosion-proof system of this glove box adopts a sealed explosion-proof box design, which is an integrated sealed explosion-proof structure for the whole machine. It is suitable for potential explosive gas environments (Zone 1/Zone 2) and dust environments (Zone 21/Zone 22), fully complying with national and international explosion-proof standards. The core configuration and technical indicators are as follows:

Explosion proof core design principles

Explosion proof type is the main type, supplemented by intrinsic safety type: the core electrical components adopt explosion-proof structure (Ex d), and the sensitive electronic components adopt intrinsic safety structure (Ex ia) to prevent electrical sparks and arcs;

Anti static design: The grounding resistance of the whole machine is ≤ 4 Ω, and the box, gloves, and pipelines are all treated with anti-static measures. The surface resistance is controlled between 10 ⁶ and 10 ⁹ Ω to prevent the accumulation of static electricity and the generation of static sparks;

Sealed Explosion proof: The overall design of the sealed explosion-proof box is adopted, which can effectively isolate the infiltration or leakage of flammable and explosive media, and also isolate the contact between external air and flammable and explosive materials inside the box, building a strong explosion-proof safety defense line;

Parameters of explosion-proof core components

Explosion proof electrical components: The control unit, fan motor, lighting fixtures, wiring board, and cables are all integrated into a sealed explosion-proof box, which is explosion-proof and meets the Ex d IIB T4 level. The sealed explosion-proof box shell has an explosion-proof pressure resistance of ≥ 0.3MPa, effectively protecting internal electrical components and preventing spark leakage;

Explosion proof sensor: optional combustible gas sensor (detection range 0-100% LEL, error ± 3%), linked with the control system, real-time monitoring of combustible gas concentration inside and around the box, automatic alarm for exceeding the standard and activation of protective measures;

Emergency pressure relief device: Explosion proof emergency pressure relief valve, response time ≤ 0.5 seconds. When the pressure inside the box rises abnormally, it will automatically release pressure to prevent secondary risks caused by box explosion;

Explosion proof seals: All interfaces, valves, and glove ports are equipped with explosion-proof special seals, which have excellent temperature resistance, corrosion resistance, and sealing performance to prevent medium leakage.

The explosion-proof system of this equipment adopts a sealed explosion-proof box design, which is suitable for the operation of flammable and explosive materials such as lithium battery materials, organic metals, explosive powders, and military chemicals. It can be safely used in scenarios with potential explosion risks such as petrochemicals, lithium battery manufacturing, and fine chemicals. The sealed explosion-proof box combines multiple measures such as inert gas protection, explosion-proof electrical control, and electrostatic protection to comprehensively eliminate the risk of explosion and ensure the safety of equipment, personnel, and the environment.
