Gas lift reverse circulation slurry suction head device
The invention discloses an air lift reverse circulation slurry suction head device which comprises a main shell, a plurality of slurry suction openings are formed in the periphery of the main shell in a surrounding mode, an upper frustum part is arranged on the upper portion of the main shell, an upper guide pipe connector is connected to the upper end of the upper frustum part, and an air bag cavity shell is arranged on the upper frustum part. An air bag cavity is formed among the air bag cavity shell, the upper frustum portion and the upper guide pipe connector, an air bag exhaust hole is formed in the side wall, along the upper guide pipe connector, of the air bag cavity, and an air pipe connector is arranged on the air bag cavity shell. The air bag cavity, the air bag exhaust hole, the main shell and the slurry suction port form an air lift reverse circulation system, high-pressure air is fed into the air bag cavity shell through the air pipe connector and then mixed with slurry in the air bag cavity, a pressure area is generated in the air bag cavity after inflation, the pressure difference between the inside and the outside of the continuous inflation slurry suction head is continuously increased, and after a certain pressure difference is achieved, balance is broken, and the slurry suction head is continuously inflated. And the slurry is forced to return upwards and be sprayed out through the slurry suction port and the guide pipe joint under the high-pressure effect.
本发明公开了一种气举反循环吸浆头装置，包括主壳体，主壳体沿四周环绕设有多个吸浆口，主壳体的上部设置有上锥台部，上锥台部上端衔接有上导管接头，上锥台部上设置有气包腔外壳，气包腔外壳与上锥台部、上导管接头之间形成气包腔体，气包腔体沿上导管接头的侧壁设有气包排气孔，气包腔外壳上设置有气管接头。气包腔体、气包排气孔、主壳体及吸浆口构成一个气举反循环系统，高压空气通过气管接头送入气包腔外壳后，在气包腔体内与泥浆混合，经充气后在包腔体内产生压力区，连续充气吸浆头内外压差不断增大，当达到一定的压力差后，平衡打破，则迫使泥浆在高压作用下通过吸浆口及导管接头上返喷出。
