Abstract

Методът повишава достоверността на взиманите данни и аликвотни проби и гарантирана безаварийна работа на инсталациите. Едновременно с обичайното измерване на една или повече характеристики на насипния материал или аликвотна проба от него се измерват една или повече променливи величини, които са независими от средствата за измерване на характеристиките и влияят директно и/или индиректно върху тяхната нормална работа. Устройството включва релсово бункерно разтоварващо съоръжение (10), под което каскадно са разположени трошачка (11) и лентов транспортьор (12). Под него е прикрепена лентова везна (13), представляваща първо средство за измерване на характеристиките на насипния материал. При везната (13) е монтиран първи датчик (18), а към изходящия край на транспортьора (12) втори датчик (20), представляващ второ средство за измерване на една и/или повече променливи величини, влияещи директно и индиректно върху нормалната работа на първото средство за измерване. Тези величини са с влияние върху точността и надеждността на резултатите, получени от първото средство за измерване. Към устройството е включен компютър (57). 8 претенции, 4 фигуриThe method increases the reliability of the collected data and aliquot samples and guarantees trouble-free operation of the installations. Simultaneously with the usual measurement of one or more characteristics of the bulk material or an aliquot thereof, one or more variables are measured which are independent of the means of measuring the characteristics and affect directly and/or indirectly their normal operation. The device includes a rail hopper unloading facility (10), under which a crusher (11) and a belt conveyor (12) are cascaded. A tape scale (13) is attached below it, representing a first means of measuring the characteristics of the bulk material. A first sensor (18) is installed at the scale (13), and a second sensor (20) is installed at the output end of the conveyor (12), representing a second means of measuring one and/or more variable quantities affecting directly and indirectly the normal operation of the first means of measurement. These quantities have an influence on the accuracy and reliability of the results obtained by the first measuring tool. A computer (57) is included with the device. 8 claims, 4 figures
