第十五届中国专利奖评选结果在京揭晓,赛摩电气股份有限公司的“一种高精度皮带称重装置(专利号201010548484.5)”专利获“中国专利优秀奖”。该专利采用集称重与物料校准于一体的皮带秤称重装置,用两台皮带秤架和一台容积秤斗,并利用一台称重控制仪表实现在线自动采集少量物料代替多物料进行皮带秤精度对比、校准,实现高精度称量。在皮带机输送物料前,称重控制仪表通过自动脉冲计数建立皮带自重校准始点,以此校准始点对大于容积秤斗容纳标准物料的输送时间内皮带移动长度的皮带自重进行自动调零,
The results of the 15th China Patent Award were announced in Beijing. “A high-precision belt weighing device (Patent No. 201010548484.5)” won the “China Patent Excellence Award” by the SAA Electric Co., Ltd. ". The patent uses weighing and material calibration in one of the belt scale weighing device, with two belt scale frame and a volume scale bucket, and the use of a weighing control instrument online automatically capture a small amount of material instead of multi-material belt Scale accuracy contrast, calibration, to achieve high-precision weighing. In the belt conveyor before the material, weighing control instrument through the automatic pulse count to establish the starting point of self-weight calibration of the belt, in order to calibrate the starting point for more than the volume hopper to accommodate the standard material transfer time within the belt movement length of the belt self-
