Description
Недостатком известных сиг 1алпиаг()11ов дипжени пульпы вл етс возможность возникновени ложного внечатлени неподвижности пульпы , когда пульсаци электропроводности отсутствует, что имеет место при прохождении ио иульноводу чистой воды.A disadvantage of the known pulparial pulp is the possibility of a false impression of the immobility of the pulp when there is no conductivity pulsation, which occurs during the passage of pure water to the inlet water.
Предлагаемый сигнализатор отличаетс тем, что нозвол ет определ ть прохождение по пульповоду чистой воды, когда пульсаци электропроводности отсутствует. Это достигаетс тем, что в нем применен р д датчиков, размешенных на различной высоте относительно оси пульповода , попеременно подключаемых к измерителю протекающих через датчики токов. Равенство этих токов свидетельствует о прохождении по пульповоду чистой воды.The proposed signaling device differs in that it makes it possible to determine the passage of pure water along the slurry line when there is no conductivity pulsation. This is achieved by the fact that it employs a series of sensors placed at different heights relative to the axis of the slider, alternately connected to the meter by the currents flowing through the sensors. The equality of these currents indicates the passage of pure water through the pulpwater.
Сигнализатор состоит из датчиков /. 2, 3 (см. блок-схему), располагаемых на разных высотах по стенке пульповода; линип св зи межд дагчиками и индикатором 4 и усилительного устройства ,Т со световым индикатором 4.The detector consists of sensors. 2, 3 (see block diagram), located at different heights along the slurry line; line of communication between the two sensors and the indicator 4 and the amplifying device, T with the light indicator 4.
Датчик иредставл ет собой три э;1ектрода, изолированных друг от друга от CTCiiOK пульповода и выступающих на 1-2 мм в иоток. Каждый датчик может с помондью переключател 6. расположенного на vieредией пан(ли прибора, подключатьс к силительном устройству .. .Междуэлектродиые сопротивлени датчиков, образуемые ироводи .мостью гидросмеси, вместе с сопротивлени ми 7 и 8 образуют мостовую схс.. к одной диагонали которой подводитс 1П1таю1иес наир жен.ие, а ко второй диагонали через конденсатор и фильтр подключаетс вход первого каскада усилител . Поскольку наиболее интепсивные .)1ии наир жени , вызванные движением иульпы. иаход тс в области инфразвУ1овых частот, схема выполиена таким образом, чтобы уси.швалисг им( эти частоты, что обеспечиваетс ирименением больних зиаченш иерсходных с Мкостей.The sensor represents three e; 1 spectrodes, isolated from each other from the CTCiiOK slurry line and protruding 1-2 mm into the current. Each sensor can switch a switch 6. located on the middle of the panel (whether the device is connected to a silicon device ... The electrode resistances of the sensors formed by the conduction of the slurry, together with the resistances 7 and 8, form a bridge circuit. The diagonal of which is supplied 1P1nuyu1ees nairu, and to the second diagonal through a capacitor and a filter connects the input of the first cascade amplifier. As the most intusive.) 1i ni na tion, caused by the movement of the pulp. and is in the area of infrasonic frequencies, the scheme is made in such a way that usi shalisms (these frequencies, which is ensured by the introduction of sickness and other conditions with masses).
