Spiral pneumatic conveying system for medicament

The invention provides a spiral pneumatic conveying system for medicaments, which comprises a conveying pipeline, and further comprises a spiral flow guide section arranged at the upstream of the bent part of the conveying pipeline along the conveying direction of the conveying pipeline; the leakage detection unit is arranged at the bent part of the conveying pipeline and is used for detecting whether gas leakage exists at the bent part of the conveying pipeline or not; the alarm unit is electrically connected with the leakage detection unit and used for sending out alarm information when gas leakage occurs at the bending position of the conveying pipeline, the spiral flow guide section is arranged, airflow can be guided to form rotating airflow, the rotating airflow can rotate when passing through the bending position of the conveying pipeline, and the gas leakage detection effect is improved. The problem of accumulation of medicament particles on the inner side of the bent part can be reduced or avoided, th
