The invention discloses a medicament screening device for
pharmacy. The medicament screening device comprises a bottom plate, a swing flow dividing structure, a connecting
pipe and a clearing structure. The swing flow dividing structure is arranged on the top side of the bottom plate, the clearing structure is erected above the bottom plate, and the clearing structure communicates with the swing flow dividing structure through the connecting
pipe. Medicament needing to be screened is supplemented into a screening box through a feeding
pipe, an emptying pump and a pressurizing
air pump work synchronously, the interior of an air blowing box is pressurized through the emptying pump, the impulsive force generated by air pressure is controlled to be lower than the
mass of tablets, when drugs slide along the inner wall of a screening hopper,
powder slag can be blown through air holes, the emptying pump works to empty a storage box, the internal air pressure of the storage box is reduced,
powder slag in the medicament can be discharged through a dust discharging pipe,
primary screening of the medicament is achieved, the
powder slag in the medicament is removed, subsequent screening can be convenient, medicament screening interference is reduced, the powder slag can be recycled in a concentrated manner, and the powder slag is prevented from being polluted.
