Dry powder dispensing apparatus

Abstract

The invention discloses a dry powder dispensing apparatus, comprising a medicine adding system, a water supplying system, a dispensing device and a stirring buffer tank, wherein the medicine adding system comprises a medicine weighing device, a blower and a medicinal powder conveying pipeline; the blower is connected with one end of the medicinal powder conveying pipeline; the medicine weighing device is connected with and arranged above the medicinal powder conveying pipeline; medicinal powder discharged by the medicine weighing device is conveyed to a medicine spraying nozzle of the dispensing device via the blower; the water supplying system comprises a water pump and a water pipe; the water pump conveys water to the water pipe; high pressure water flow is conveyed to a water spraying head of the of the dispensing device via the water pipe; and the water is sprayed onto a funnel surface of the dispensing device at a high speed via the water spraying head. The dry powder dispensing apparatus employs a multi-layer funnel structure, and high-speed water flow and medicinal powder are mixed via rapid rotation in funnels so as to realize dispensing, so mixing of water and medicinal powder is more uniform and faster, the phenomenon of fish eyes and agglomeration effect are avoided, and dispensing quality and dispensing effect are greatly improved.

Description

technical field [0001] The invention relates to a medicine dispensing device, in particular to a dry powder medicine dispensing device. Background technique [0002] The volume of the existing dispensing equipment ranges from a few liters to several thousand liters. Most of the medicine powder and the solvent are poured into a container in proportion, and the solvent and the medicine powder are stirred by a stirring shaft. The disadvantage of this form is: as the volume of the mixer increases and the length of the rotating shaft becomes longer, the rotating shaft is easily bent and deformed during the working process, which will cause the machine to malfunction or be stuck; in order to improve the rigidity of the rotating shaft, and The diameter of the rotating shaft has to be increased, thereby increasing the manufacturing cost and the user's operating cost, thereby restricting the volume of the mixer and making continuous dispensing impossible.
