真空称重系统由投料站或物料储仓、真空加料机称重装置、PLC控制器等部件组成,可完成单物料定重量加料或多种物料不同配方配料的自动供料配料。广泛应用于医药、食品、化工、电池材料、建材、冶金、饲料加工等行业。

以粉体真空称重系统应用于两种物料自动称重配料为例说明粉体真空承重系统的工作原理。物料A、B分别储存在两个料仓中,粉体真空称重系统开始工作,真空泵启动,物料A粉仓底部螺旋放料阀A达到一定重量时,螺旋停止,放料阀A关闭,剩余在输送管中的物料继续被吸入到称重料斗中,吸净后秤中物料A的重量正好是设定的重量。此时,物料B料仓底部螺旋放料阀B打开,螺旋启动,物料B被吸入称重料斗中,秤中物料B达到一定重量时,螺旋停止,放料阀B关闭,剩余在输送管中的物料继续被吸入到称重料斗中,吸净后秤中物料B的重量正好是设定的重量。真空泵停止。

真空称重系统较传统的粉体称重系统具有工艺流程短、称重精度高、可靠性高、设备布局高度灵活、大幅降低厂房高度等优点。根据称重装置在粉体真空称重系统中不同位置,可组成多种加法秤、减法秤,以适应客户的不同要求。

Vacuum weighing system is composed of feeding station or material warehouse, vacuum feeder weighing device, PLC controller and other components。 It can complete the automatic feeding of single material with fixed weight or different ingredients of various materials。 It is widely used in medicine, food, chemical industry, battery materials, building materials, metallurgy, feed processing and other industries。

Taking the application of powder vacuum weighing system in automatic weighing and batching of two kinds of materials as an example, the working principle of powder vacuum weighing system is explained。 Material A and B are stored in two silos respectively。 The powder vacuum weighing system starts to work。 The vacuum pump starts。 When the screw discharging valve A at the bottom of material A reaches a certain weight, the screw stops and the discharging valve A closes。 The remaining material in the conveyor pipe continues to be sucked into the weighing hopper。 After being sucked, the weight of material A in the scale is just right。 It's the set weight。 At this time, the screw discharging valve B at the bottom of material B bin opens, the screw starts, material B is absorbed into the weighing hopper。 When material B reaches a certain weight in the scale, the screw stops, the discharging valve B closes, and the remaining material in the conveyor pipe continues to be absorbed into the weighing hopper。 The weight of material B in the scale is exactly the set weight after absorption。 The vacuum pump stops。

Compared with the traditional powder weighing system, vacuum weighing system has the advantages of short process flow, high weighing accuracy, high reliability, highly flexible equipment layout, and greatly reducing the height of factory buildings. According to the different positions of the weighing device in the powder vacuum weighing system, a variety of additive and subtractive weighing scales can be formed to meet the different requirements of customers.
