AI Technical Summary
Existing coal mine gas drainage pipeline systems cannot effectively handle waste residue under high pressure and cannot achieve uninterrupted slag discharge operations, affecting gas drainage efficiency and safety.
A device comprising two sets of slag discharge components was designed to achieve uninterrupted gas extraction through alternating operation of the slag discharge components and to simultaneously process waste slag under high pressure. The waste slag is filtered by a filter plate and pushed out by a pusher plate, and the sealing and safety are ensured by a combination of a sealing plate and an electromagnet block.
This enables uninterrupted operation of gas extraction, improves slag removal efficiency and safety, and avoids equipment damage and accident risks caused by blockage.
