【摘要】：定量给料机广泛应用于建材、冶金、电力、化工、煤炭、矿山、烟草、食品和环保等行业。它是对散状物料进行连续称量给料的理想设备,能适应各种生产环境,可对各种块状、粒状和粉状物料等进行连续给料、计量。因此努力提高给料系统的给料精度和自动化程度就有着十分重要的现实意义,并且,将传统的机械系统和计算机控制相结合,利用机电一体化技术也是顺应工业发展方向。首先,本文设计了一个小型电磁振动给料机,并对该给料机进行了调试,使其能连续平稳的工作,它的实际给料能力是4t/h。根据该电磁振动给料机的给料能力,本文还设计了与之相适应的冲击式流量计,分析得出该流量计交流电桥部分产生的电压与铁芯的位移即电磁振动给料机的瞬时流量基本成正比。然后,本文采用西门子公司的S7-200PLC作为计量控制器,对整个系统进行PID闭环控制,将PLC输出的电流输入给电振机控制箱,利用控制箱实现对电磁振动给料机振幅的调节。此外,本文还应用WinCC组态软件设计了本系统的控制界面,使监视、管理、控制运行过程更加直观方便。最后,本文用实验的方法对系统进行了标定,并确定了给料机的给料上限,对系统的控制性能进行了分析,实验表明,系统定量给料效果良好。
[Abstract]:Ration feeder is widely used in building materials, metallurgy, electric power, chemical industry, coal, mine, tobacco, food and environmental protection. It is an ideal equipment for continuous weighing and feeding of bulk materials, which can be adapted to various production environments, and can be used for continuous feeding and metering of various bulk, granular and powdery materials. Therefore, it is of great practical significance to improve the feeding accuracy and automation of the feeding system, and the combination of traditional mechanical system and computer control, the use of electromechanical integration technology is also in line with the direction of industrial development. Firstly, a small electromagnetic vibration feeder is designed and debugged to make it work smoothly and continuously. Its actual feed capacity is 4 t / h. According to the feeding capacity of the electromagnetic vibration feeder, an impact Flowmeter is designed. It is concluded that the voltage generated by the AC bridge of the Flowmeter is directly proportional to the displacement of the iron core, that is, the instantaneous flow rate of the electromagnetic vibration feeder. Then, the S7-200PLC of Siemens is used as the measurement controller, the whole system is controlled by PID closed loop, the output current of PLC is fed into the control box of electric vibration machine, and the amplitude of electromagnetic vibration feeder is adjusted by using the control box. In addition, the control interface of the system is designed by using WinCC configuration software, which makes the monitoring, management and control process more intuitive and convenient. Finally, the system is calibrated by the method of experiment, the upper limit of the feeder is determined, and the control performance of the system is analyzed. The experiment shows that the quantitative feeding effect of the system is good.
