设备简介
Equipment Introduction
The lock gas ash discharge device is used in the after - filter system. Its core function is to isolate the filter element chamber of the after - filter from the waste powder collection box. By controlling the switching of two valves, it discharges the powder in the after - filter into the waste powder collection box, and blocks the transmission of explosion impact to avoid the risk of secondary explosion.
设备描述
Device Description
(1) 安装位置：安装于后过滤器滤芯室的锥形锥斗底部，与后过滤器结构适配。
Installation position: Installed at the bottom of the conical hopper of the filter element chamber of the after - filter, matching the structure of the after - filter.
(2) 工作控制：通过电磁阀控制两个蝶阀的启闭动作，实现后过滤器滤芯室与废粉收集箱的物理隔离与粉末排放：
Working control: Control the opening and closing of two butterfly valves through a solenoid valve to achieve physical isolation between the filter element chamber of the after - filter and the waste powder collection box and discharge the powder:
u 粉末排放流程：上阀开启时，后过滤器内超细粉末落至两阀中间储存区；上阀关闭后，下阀开启，粉末排放至废粉收集箱；下阀关闭后，恢复物理隔离状态，循环执行。
Powder discharge process: When the upper valve opens, the ultra - fine powder in the after - filter falls into the storage area between the two valves; after the upper valve closes, the lower valve opens to discharge the powder into the waste powder collection box; after the lower valve closes, the physical isolation state is restored and executed cyclically.
u 故障预警：若任一蝶阀故障，触发声光报警，提示设备异常，避免因阀门失效引发安全风险。
Fault warning: If either butterfly valve fails, an acousto - optic alarm is triggered to indicate equipment abnormality and avoid safety risks caused by valve failure.
功能及特点
Functions and features
(1) 核心防护：构建后过滤器滤芯室与废粉收集箱的物理隔离，阻断燃爆冲击传递，防止后过滤器燃爆时，废粉收集箱内粉末受冲击引发二次燃爆。
Core protection: Establish physical isolation between the filter element chamber of the after - filter and the waste powder collection box, block the transmission of explosion impact, and prevent the powder in the waste powder collection box from being impacted to cause secondary explosion when the after - filter explodes.
(2) 合规适配：满足粉尘爆炸危险场所除尘系统安全要求及干式除尘器/粉尘防爆安全规范，为干式过滤器配套提供合规保障。
Compliance adaptation: Meet the safety requirements of dust collection systems in dust explosion hazard areas and the safety specifications for dry dust collectors/dust explosion protection, providing compliance guarantee for dry filter matching.
(3) 智能控制：电磁阀精准控制蝶阀启闭，配合故障声光报警，保障粉末排放流程稳定，及时预警设备异常。
Intelligent control: The solenoid valve accurately controls the opening and closing of the butterfly valve, combined with fault acousto - optic alarm, to ensure the stability of the powder discharge process and timely warn of equipment abnormalities.
