Pneumatic conveying pump

The utility model relates to a pneumatic conveying pump which comprises a sending tank, a driving device is installed at the bottom of the sending tank, the output end of the driving device is connected with a stirring shaft, the stirring shaft penetrates through the bottom of the sending tank and extends into the sending tank, and a double-spiral material loosening blade is fixedly arranged on the stirring shaft. And the driving device can drive the double-helix material loosening blade to rotate in the sending tank for material loosening. The driving device is additionally arranged to adjust the flow speed of materials entering the gasification chamber, so that the concentration and the conveying speed of the gasified materials are stable, pipe blockage is avoided, and meanwhile, a double-helix material loosening structure is combined to further prevent the materials from being accumulated and blocked to affect conveying operation. 本实用新型涉及一种气力输送泵，包括发送罐，所述发送罐的底部安装有驱动装置，所述驱动装置的输出端连接有搅拌轴，搅拌轴穿过发送罐底部延伸至发送罐内，所述搅拌
