Abstract
To solve the problems of high labor intensity,poor accuracy,and low mixing uniformity in manually adding cementing and plugging materials,an automated metering and adding device for cementing and plugging materials was developed,mainly consisting of silos,belt metering,and hose spiral conveyors. The device was designed with PLC as the core and touch screen as the human-machine interaction interface. The main hardware includes a level gauge,frequency converter,weighing sensor,and variable frequency motor. The device adopts an expert PID control strategy to achieve signal acquisition,logic control,and data communication. Through automated testing of extreme conveying of fiber materials at 3～5 kg/min and sheet-like materials at 10～50 kg/min,the material can be continuously mixed,stirred,and uniformly and stably delivered at any position through a hose type screw conveyor,meeting the requirements for feeding measurement and conveying of two types of materials,including sheet-like materials and fiber materials,in two silos. The results show that its mixing uniformity is good,with less manual participation, stable measurement accuracy,and an error of less than ±1％;Compared to manual labor,the overall efficiency is two times higher. The research provides a support for automated operation of offshore oil drilling platforms.
