Automatic liquid medicine conveying system

Abstract

The invention discloses an automatic liquid medicine conveying system. The automatic liquid medicine conveying system comprises a main liquid medicine conveying pipeline and converging pipelines for mixing liquid medicine with different components. The main pipeline is provided with a plurality of standby branch pipes which are used for reducing the flow speed of liquid medicine so as to reduce the increase of the flow speed of fluid caused by the change of conveying potential energy. According to the automatic liquid medicine conveying system, when adjustment or height change is needed to adapt to the actual pipe distribution requirement, the flow speed of the pipeline part of the main pipeline part is increased or decreased, the part where the flow speed is improved is provided with the standby branch pipes, and the opening degree of flow valves is adjusted, so that the flow of divided fluid is adjusted, and the effect of adjusting the flow speed of the fluid in the main pipeline is achieved; and a fluid conveying machine capable of providing higher conveying energy is pre-selected in advance according to a pipe arrangement design drawing for the part with the reduced flow speed. For mixing which only needs normal temperature and normal pressure, the converging pipelines are arranged, so that a subsequent liquid preparation tank is directly omitted, the liquid preparation process is synchronously completed on line in the conveying process, the production efficiency is improved, and the number of equipment of a subsequent system is reduced.

Description

technical field [0001] The invention relates to an automatic medicinal liquid delivery system. Background technique [0002] In the liquid medicine transportation, the pipeline equipment material is generally 316L stainless steel, and the liquid conveying machine needs to supply energy to the liquid medicine to transport the liquid medicine from the low energy level to the high energy level, and the liquid medicine is subject to flow resistance when flowing in the pipeline. Since the flow resistance increases with the increase of the flow velocity, it is required that the mechanical energy added by the fluid delivery machine to the unit weight of the fluid, that is, the liquid medicine, increases with the increase of the flow velocity. At present, when laying pipes in the conveying system, the structure of the site itself needs to be adjusted or the height needs to be changed to meet the actual pipe laying needs. Changes in the flow resistance cause fluctuations in the proc...

AI Technical Summary

Problems solved by technology

At present, when laying pipes in the conveying system, due to the need for some adjustments to the structure of the site itself or the need to change the height to meet the actual pipe laying needs, this will cause changes in the energy level, and the flow rate of some sections of the pipe will increase or decrease, which will Changes in flow resistance cause fluctuations in the process of delivering liquid medicine, which is not conducive to the stability of the delivery system and the extension of its service life

In addition, liquid dispensing tank is an indispensable equipment for the pharmaceutical industry, and its cost is relatively high. At present, some enterprises use liquid medicine to transport to liquid dispensing tank. Put it into the liquid mixing tank under the temperature environment, mix and stir, and then fill it to form the final product, such as oral liquid, etc., so the production efficiency is not high, and it needs to be transported to the liquid mixing tank before filling
