一、问题的提出 建材行业中的配料计量技术至今尚未得到根本的解决,例如:粉料、砂料及大流量的骨料的计量与控制技术问题。我们在深入研究各种对象的计量与控制方案后,提出了失重秤方案,其最大特点是:基本不考虑运行中物料的运动特性,具有适应多种物料品种的计量,能做到大流量、快速且满足精度要求。 该方案采用斗(仓)式计量结构,如图1所示。斗(仓)的容量较大(可超过10m~3);斗(仓)内物料需要间断的加料(有冲击特性,如铲车加料)。整个料斗和卸料皮带一体用四个荷重传感器予以支撑,压力传感器输出信号以串联方式联结,平衡地
First, the issue put forward Building materials industry ingredients metering technology has not yet been fundamentally resolved, for example: powder, sand and large flow aggregate measurement and control technology issues. After thoroughly studying the metrology and control schemes of various objects, we put forward the program of weight loss scale. The most prominent feature of this program is that it basically does not consider the movement characteristics of materials in operation, has the ability to measure the variety of materials and can achieve high flow, Fast and meet the accuracy requirements. The program uses bucket (warehouse) metering structure, shown in Figure 1. Bucket (tank) larger capacity (more than 10m ~ 3); Bucket (warehouse) materials need intermittent feeding (with impact characteristics, such as forklift feeding). The whole hopper and the unloading belt are supported by four load cells, the pressure sensor output signals are connected in series and balancedly
