Dynamic Weighing Method Solid Bulk Device

Solid bulk dynamic weighing device is a kind of dynamic testing equipment, in scientific research, production and daily management plays a very important role in the life. At present, the solid powder dynamic weighing used in device of electronic belt scale, impact flow meters, nuclear scale and gravity scale, but they are all flawed: electronic belt scale need frequent repairs, receiving plate flowmeter signal is not stable, nuclear belt scale measurement is not accurate, weightlessness balance materials prone to congestion. Based on the above problems, the experimental research on the new type of solid weighing device become very necessary.Papers in given the original dynamic weighing device on the measuring principle and the structure model, established a new mechanical model, using physical analysis, deduced the principle of a new type of dynamic weighing, and according to the principle of device design.In the design of mechanical parts, connected by three-step chute in the structure, to shorten the measurement time, avoid the material blockage, in addition, three sensors in the structure of the data collection, reception for stability.Software part, LabWindows/CVI programming software and supporting the use of Modbus debugging software, provide effective guarantee for the stability of the measurement.After finish the design,build a new weighing device test rig, the assembly process import in CVI software, found that the initial level of thimble connection between sensor and measuring reservoir lead to inaccurate sensor receives the signal, the modified for the connection of the steel connection mode, very good solve the problem.Dynamic weighing test rig, new type of solid powder in between different materials, materials with different status after a large number of repetitive measurement experiment, the results proved it on the use of performance, is currently in use dynamic metering device has obvious advantages.New type of solid powder dynamic weighing device can be widely applicable to steel mills, coal mine, port, cigarette factory need to keep the continuous dynamic measurement of places, it has simple structure, cheap in cost, high measuring precision, small amount of maintenance and other characteristics, as well as a great engineering application value.
