Description
(54) СИСТЕМА АВТОМАТИЧЕСКОГО ДИСКРЕТНОГО КОНТРОЛЯ ТЕМПЕРАТУРЫ В ТЕХНОЛОГИЧЕСКИХ(54) SYSTEM OF AUTOMATIC DISCRETE CONTROL OF TEMPERATURE IN TECHNOLOGICAL
Изобретение относитс к технике измерени температуры жидких электропроводных сред в технологических агрегатах, например электролита в алюминиевых электролизерах .The invention relates to a technique for measuring the temperature of liquid electrically conductive media in process units, for example, electrolyte in aluminum electrolysers.
По основному авт. св. № 4О2756 известна система автоматического дискретного контрол температуры в технологических агрегатах, в которой теплоприемник при измерении опускаетс на посто ниое рассто ние. При изменении уровн измер емой среды термоприемник оказываетс погруженным в эту среду на различную глубину, что снижает точность контрол температуры,.; особенно при значительном градиенте температуры в измер емой среде .According to the main author. St. No. 4О2756 is known a system of automatic discrete temperature control in technological aggregates, in which the heat sink is lowered at a constant distance during the measurement. When the level of the measured medium changes, the thermal receiver is immersed in this medium at different depths, which reduces the accuracy of temperature control,; especially with a significant temperature gradient in the measured medium.
Целью изобретени вл етс повышение точности контрол температуры за счет стабилизации глубины погружени термоприемника в контролируемую среду.The aim of the invention is to improve the accuracy of temperature control by stabilizing the depth of the thermal receiver in a controlled environment.
Поставленна цель достигаетс тем, что термоприемник размещен в выполненном из электропроводного материала защитном чехле, соединенном через источник The goal is achieved by the fact that the thermal receiver is placed in a protective sheath made of electrically conductive material connected through a source
питани и контролируемую электропровод щую среду со входом введенного в систеьу задатчика времени, выход которого соединен из входов командного устройства.power supply and controlled electrically conducting medium with the input of the time unit introduced into the system, the output of which is connected from the inputs of the command device.
В такой системе дл контрол термоприемник перемещаетс с посто нной скоростью и в каждом цикле контрол фиксируетс момент касани электропроводным чехлом термоприемника изм емой среды. Термоприемник в измер етисЛ среде перемещаетс в течение времени, отсчитываемого с момента касани чехла гермоприемнике измер емой среды, определ емого задатчиком времени и посто нного дл всех циклов контрол , В результате обеспечиваетс посто нство глубины псмгружени термоприемника в измер емую среду независимо от ее уровн .In such a control system, the thermal receiver moves at a constant speed, and in each control cycle the moment of contact is recorded by the electrically conductive sheath of the thermal receiver of the medium being measured. The thermal receiver in the measuring medium of the medium moves during the time counted from the moment the sheath touches the pressure transducer of the measuring medium, which is determined by the time master and is constant for all control cycles. As a result, the thermal load of the thermal receiver is constant into the measured medium regardless of its level.
На чертеже прецставлена блок-схема описываемой системы.The drawing shows the block diagram of the described system.
Система содержит заиштный чехол 1 из электропроводного материала (;йапример: из графита) с установленным в нем термоприемником 2 (термопарой), устройство 3 ввода-вывоаа термоприемника вThe system contains a protective cover 1 made of electrically conductive material (; for example: graphite) with a thermal receiver 2 installed in it (thermocouple), the device 3 input-output thermal receiver in
