A methanol storage tank supply and output control device for the manufacture of pharmaceuticals

Abstract

The present invention provides a methanol storage tank supply and output control device for manufacturing medicines, which includes a control mechanism 1 for controlling the supply of methanol in the methanol storage tank and a control mechanism 2 for controlling the output of methanol in the methanol storage tank; The control mechanism 1 includes a liquid level glass tube 1 arranged on one side of the methanol storage tank and communicated with the methanol storage tank 1 and a controller. The output terminal is connected to the supply pump signal; the control mechanism 2 includes the liquid level glass tube 2 and the controller 2 which are arranged on the other side of the methanol storage tank and communicated with the methanol storage tank. The liquid level lower limit sensor is connected to the second signal, and its output terminal is connected to the output pump signal. The control device of the invention has the advantages of simple structure, strong versatility, high liquid level measurement accuracy and high liquid level measurement stability, and meets the needs of the pharmaceutical manufacturing industry.

Description

technical field [0001] The present invention relates to the technical field of equipment used for medicine manufacture, and more specifically, relates to a methanol storage tank supply and output control device for medicine manufacture. Background technique [0002] There are a variety of anti-infection and anti-inflammatory APIs - sulfonamides, macrolide APIs (such as sulfamethazine and its sodium salt, sulfadiazine and its sodium salt, sulfamethoxazole and trimethoprim ) and pharmaceutical raw materials such as roxithromycin, which are usually used to treat infections caused by staphylococcus, streptococcus, pneumococcus and meningococcus. [0003] Methanol is a common important auxiliary raw material commonly used by pharmaceutical manufacturers to manufacture the above-mentioned pharmaceutical raw materials. Methanol is used as a medium such as a condensation agent and a strong basic catalyst to prepare various anti-infective and anti-inflammatory raw materials. It is us...

AI Technical Summary

Problems solved by technology

However, the above-mentioned manual judgment of the liquid level of methanol in the methanol storage tank will be subjective, and the relevant data in the methanol storage tank cannot be measured quickly, reliably and accurately, resulting in low accuracy of liquid level judgment and methanol output error. Various problems such as large size, insufficient methanol supply and low pharmaceutical efficiency

The existing method has the problems of high difficulty in liquid level measurement and low measurement accuracy. Not only can it not reflect the situation information of methanol in the methanol storage tank in time, but it also cannot effectively ensure the required output of methanol added to pharmaceutical raw materials during the manufacturing process of pharmaceutical raw materials. content and the supply of methanol in the storage tank, thus affecting the medicinal properties and efficacy of pharmaceutical raw materials
