Description
称量控制原理如下:
若检测重量大于快供值,则球阀开;若检测重量大于慢供值且小于快供值,则球阀点动开关; 若检测重量大于提前值且小于慢供值,则球阀关闭.
料浆制备
配料锅分为A锅及B锅两个,可进行单锅或双锅交替配料,制备完成的料浆经过滤锅及暂存锅送至高压泵,然后喷入塔内干燥.在制备过程中,若发生断料或堵料等异常状况,配料周期自动暂停,恢复正常后,周期自动恢复运行.
前配料部分(包括固体称量、液体称量及料浆制备部分)可通过在配方编辑表填入相应数据,然后启动配料周期自动进行配料.
喷雾干燥
包括尾气温度控制、沉降室压力控制、进塔料浆回流控制、脱气罐料位控制等PID控制回路,所有PID控制参数均有相应的操作面板,可对有关参数进行修改.
