[0002] In the pulverized coal gasification process, pulverized coal is conveyed under pressure, and the device includes a pulverized coal lock bucket. In the pulverized coal gasification process, the pulverized coal in the high-pressure lock bucket is prone to plate accumulation due to its own gravity. N2 or CO2 gas needs to be filled to loosen the pulverized coal under high pressure to achieve powder homogenization. In the pulverized coal lock bucket, an inflatable flute is used to loosen the pulverized coal in the lock bucket to keep the pulverized coal pipeline unobstructed. The working conditions inside the pulverized coal lock bucket are harsh and are in a state of alternating high and low pressures. The inflatable flute is connected to the inflatable pipe and the gas supply tee on the lock bucket. At present, the inflatable flute and the gas supply tee are connected in such a way that the inflatable flute uses a square flange to clamp the gas supply tee on both sides and fasten it with four stud bolts. This connection method is not stable enough in structure and has poor sealing performance. It is easy for pulverized coal to enter the flute tube and cause blockage. The flute tube is often bent or otherwise damaged. At the same time, it is difficult to install and difficult to repair after blockage, causing damage to production and huge economic losses.
