Abstract

The invention provides a chemical raw material conveying system controlling an automatic liquid level based on computers. The system is mainly composed of a material conveying valve, tanks, the computers, programmable logic control cabinets (hereinafter referred to as PLC control cabinets), pneumatic cut-off valves, a tank field delivery pump and an electronic scale. The chemical raw material conveying system mainly achieves the purpose that a production post can realize automatic material conveying by controlling a computer system.

Description

technical field [0001] The invention relates to the fields of industrial control and chemical industry, in particular to a chemical raw material conveying system based on computer-controlled automatic liquid level. Background technique [0002] Xinhua Pharmaceutical Co., Ltd., as a large pharmaceutical manufacturer, needs a large amount of chemical liquid raw materials in the production process. In the past, when transporting materials, in order to ensure the accurate and timely delivery of materials, it often required a lot of manpower. Moreover, some materials, such as the highly toxic chemical dimethyl sulfate and the highly corrosive chemical formic acid, etc., still have great safety risks during the transportation of such dangerous materials. Programmable logic controller (hereinafter referred to as PLC system) is a digital operation electronic system specially designed for application in industrial environments. It uses a programmable memory to store instructions fo...
