Abstract
Способ автоматического контроля крупности частиц в потоке пульпы, включающий периодическое ощупывание частиц материала микрометрическим щупом с преобразованием величины частиц, зафиксированных механизмом ощупывания, в электрический сигнал, пропорциональный их абсолютному размеру, отличающийся тем, что отбирают пробу пульпы для анализа, фильтруют, направляют в кондиционирующую емкость, измеряют плотность пробы в кондиционирующей емкости, при этом разбавляют пробу пульпы водой до состояния, обеспечивающего получение монослоя частичек материала при фиксировании их микрометрическим щупом, затем производят прокачку разбавленной пробы в режиме циркуляции по контуру, включающему кондиционирующую емкость и камеру измерения, и осуществляют измерение крупности частичек материала в циркулирующем потоке, проходящем через камеру измерения, в течение периода времени, длительность которого задается по результатам предварительной калибровки, и производят вычисление содержания контролируемого класса по результатам измерения содержаний промежуточных классов крупности.A method for automatically controlling particle size in a pulp stream, including periodically palpating material particles with a micrometer probe, converting the particles recorded by the palpation mechanism into an electrical signal proportional to their absolute size, characterized in that a pulp sample is taken for analysis, filtered, and sent to an air-conditioning container , measure the density of the sample in the conditioning tank, while diluting the pulp sample with water to a state that provides a partial monolayer when it is fixed with a micrometer probe, then the diluted sample is pumped in a circulation mode along a circuit including an air-conditioning container and a measurement chamber, and particle size is measured in a circulating stream passing through the measurement chamber over a period of time, the duration of which is specified by the results of preliminary calibration, and the content of the controlled class is calculated according to the results of measuring the contents of intermediate classes of fineness.
