具体实施方式 Detailed ways

参见图1,螺旋称重系统包括手动插板阀1、贮料仓8、螺旋给料机2、 进料溜子3、称重仓9、计量螺旋5、螺旋输送器6和出料口7,还包括用于控制螺旋给料机2的变频控制器,变频控制器安装在计量系统控制柜10 内,其中手动插板阀1位于接贮料仓8上端,贮料仓8下端依次连接进料溜子3和称重仓9,称重仓9内设置计量螺旋5,称重仓9出口依次连接螺旋输送器6和出料口7,贮料仓8入口连接螺旋给料机2;进料漏子3与称重仓9之间采用软连接4,出料口7端口也采用软连接4,螺旋给料机2吊装于贮料仓8上,以使螺旋给料机2不会直接压在计量螺旋5上。 Referring to Figure 1, a helical weighing system 1 comprises a manual flapper valve, hopper 8, screw feeder 2, the feed downpipe 3, 9 weigh bin, metering screw 5, the screw conveyor 6 and an outlet 7, further comprising a screw feeder for controlling the frequency controller, frequency controller 2 is mounted in the metering system control cabinet 10, a flapper valve wherein the manual contact material hopper 8 is located in the upper end, the lower end of hopper 8 are sequentially connected to the feed downpipe 3 and weigh bin 9, 9 heavily loaded within said metering screw 5 is provided, in turn connected to weigh bin 9 auger outlet 6 and an outlet 7, an inlet 8 connected to hopper screw feeder 2; feed funnel 3 and weigh bin using the flexible connection between 9 4, the discharge port 7 connected to port 4 also soft, lifting screw feeder 2 to the hopper 8, so that the screw feeder 2 is not pressed directly on a metering screw 5. 其基本原理为:当进料漏子3无物料进入计量螺旋5时,计量螺旋5的传感器的输出信号恒定不变,作为控制器的零值输入,工作时,打开手动插板阔l, 螺旋给料机2开始送料,物料由进料漏子3进入计量螺旋5,螺旋输送器6 对计量螺旋5的称重传感器的压力逐步增大,当出料口7开始出料时,计量螺旋5的传感器的输出信号在理想状态下应是恒定值,而实际中由于各种因素的影响,此值为一变动量值,但可稳定在控制器中设定的流量值允许误差内。 The basic principle is: when the feed funnel 3 into the metering no material helix 5, helix measurement signal from the sensor 5 is constant, as the zero value input of the controller, during operation, open the manual card width L, Auger feeder 2 starts feeding, material from the feed funnel 3 into the metering screw 5, the pressure screw conveyor 6 the load cell on the measurement coil 5 is gradually increased, when the discharge port 7 starts to discharge, metering screw sensor 5 the output signal should be constant in an ideal state, but in practice due to various factors, a change in the magnitude of this value, but can be stable in the controller the set flow rate value within the allowable error. 计量螺旋5与其它连续给料计量设备类似,其瞬时给料量Qt由 Metering screw 5 with other continuous feed metering device similar to a quantity Qt by the instantaneous

下式决定: Qt=kq"Vt (t/h) Is determined as follows: Qt = kq "Vt (t / h)

式中: Where:

qt——螺旋秤内物料的线负荷,kg/m; Vt——物料在螺旋内瞬时流动速度,m/s; k——称重系数(调试确定的常数)。 Qt-- line load material in spiral scales, kg / m; Vt-- material within the spiral instantaneous flow rate, m / s; k-- weighing coefficients (constants determined debugging).

使用时,螺旋给料机2快速向称重仓9内加料,当计量螺旋5达到上限值Gmax时,进料溜子3关闭;和料仓秤一样,计量螺旋5的称重传感器输出的平均电压信号即是仓内物料重的代表量,由PLC根据单位时间内称重仓内物料重量的损失Dg/dt,给出瞬时流量和累计流量,此外,该信号还作为测量值,经计算机运算处理,与设定值比较,以其偏差做为调节信号,输入到变频器,改变螺旋给料机2的转速,以达到定量给料的目的。 In use, the screw feeder 2 within the loading quickly to said heavily loaded 9, when the metering screw 5 reaches the upper limit Gmax, the feed downpipe 3 closed; and hopper scales as metering screw average voltage output from the load cell 5 signal that is representative of an amount of material by weight of the warehouse, from the PLC in accordance with said unit of time loss in weight of the material are heavy Dg / dt, given the instantaneous flow rate and cumulative flow, in addition, also the signal as a measured value, the arithmetic processing by the computer, compared with the set value, its deviation adjustment signal as input to the inverter, the speed changing screw feeder 2, for the purpose of dosing. 当称重仓9内物料减少到下限Gmin时就完成了一个按重量法称重的周期; PLC停止采样,再次启动螺旋给料机2,使贮料仓8内的物料快速进入称重仓9,待达到控制上限Gmax,则进料溜子3关闭停止下料。 When the reduction referred to heavily loaded with the material 9 completes a gravimetric weighing cycle limit Gmin; PLC stops sampling, start again screw feeder 2, so that the material inside the hopper into the weigh bin 9 8 quickly to be to control the upper limit Gmax, the downpipe 3 is closed to stop the feed cutting. 在向称重仓9 进料时,其下料量按容量法计测和控制。 When weigh bin 9 to feed, by which the quantity measurement and control volume method. 在按容量法计量的周期内,螺旋给料机2按前一瞬间速度运转,根据前一瞬间的流量按时间计量。 In the period metered volume method, the screw feeder 2 by the former instant speed operation, prior traffic measurement time instant. 从而实 So real
