Visual secondary air lifting device

The utility model provides a visual secondary air lifting device. The visual secondary air lifting device comprises a feeding groove; the constant-liquid-level front tank is fixedly connected with the feeding groove through a first air lifting liquid rising pipe; the gas-liquid separator tank is fixedly connected with the constant liquid level front tank through a second air lifting liquid rising pipe; and the feed liquid receiving tank is fixedly connected with one end of the gas-liquid separator tank. According to the visual secondary air lifting device, the blocking position and state of insoluble residues in a secondary air lifting system can be visually analyzed and judged, and meanwhile accumulation of the insoluble residues in the system can be prevented or blocking can be relieved. 本实用新型提供一种可视化二级空气提升装置，包括：供料槽；通过第一空气提升升液管与所述供料槽固定连接的恒液位前置罐；通过第二空气提升升液管与所述恒液位前置罐固定连接的气液分离器罐；与所述气液分离器罐一端固定连接的料液接收槽。本实用新型所述的可视化二级空气提升装置，可以直观分析并判断不溶性残渣在二级空气提升系统中堵塞位置和状态，同时可以预防不溶性残渣在系统中积累或缓解堵塞。
