Description
一、技术领域1. Technical field

二.、技术背景2. Technical background
工业生产以及工程施工中需要使用大量的粉状物料。特别是建筑施工中所要使用的散装水泥，使用量大，要求计量速度快，且水泥对环境污染严重，对空气中的潮湿度反应敏感，而目前国内外大多数用户所使用的均为传感器电子秤静态计量或快速传感器静态计量，如“一种粉状物料的自动计量装置”(ZL97209417.2)，计量的精确度有限；Continuous powder dispensing installation withflow regulatory circuit-computes rate of delivery from continuous weighings inconjunction with powder density and controlled duct characteristics(WO9007740)，因无恒压机构而使精确度受到影响；“新型转子计量秤”(CN89219398.0)采用称重传感器对环境要求高、成本高、速度慢；德国Pf公司产品、中国专利，它们的不足之处就在于速度慢。也有文献资料上提出按粉状物料体积来计量其重量，但因为大多数粉状物料的堆比重不是常量，如水泥的堆比重为0.9T/m3～1.7T/m3，而难以适用于不同种类粉状物料的计量。A large amount of powdery materials are used in industrial production and engineering construction. In particular, the bulk cement to be used in building construction requires a large amount of use, requiring fast measurement speed, and the cement is seriously polluted to the environment and sensitive to humidity in the air. At present, most users at home and abroad use sensor electronics. Static metering of scales or static metering of fast sensors, such as "an automatic metering device for powdery materials" (ZL97209417.2), the accuracy of metering is limited; Continuous powder dispensing installation with flow regulatory circuit-computes rate of delivery from continuous weighings inconjunction with powder density and controlled duct characteristics (WO9007740), because there is no constant pressure mechanism, the accuracy is affected; "New Rotor Measuring Scale" (CN89219398.0) adopts a load cell that has high environmental requirements, high cost, and slow speed; Germany Pf The shortcoming of the company's products and Chinese patents is that they are slow. It is also proposed in the literature that the weight of the powdery material should be measured according to its volume, but because the bulk specific gravity of most powdery materials is not constant, such as the bulk specific gravity of cement is 0.9T/m 3 ~ 1.7T/m 3 , it is difficult to apply Metering of different kinds of powdery materials.
