Description
II
Изобретение относитс к автоматическому регулированию процесса сушки сыпучих материалов и может бьпгь использовано дл сушки торфа в сушилках брикетных заводов.The invention relates to the automatic regulation of the drying process of bulk materials and can be used for drying peat in briquette factories.
Известны- способы автоматического регулировани процесса сушки путем подачи исходного материала и теплоносител по сигналу конечной влажности высушенного материала через блок иэбирательности fl.Known are methods for automatic control of the drying process by supplying the source material and the heat transfer medium by a signal of the final moisture content of the dried material through the unit fl.
Такой способ не может быть применен при сушке торфа, поскольку этот процесс характеризуетс запаздыванием сигнала конечной влажности материала. This method cannot be applied when drying peat, since this process is characterized by a delay in the signal of the final moisture content of the material.
Целью изобретени вл етс обеспечение качественного регулировани в процессе сушки торфа в пневмопарово- д нь1х сушилках брикетных заводов.The aim of the invention is to provide quality control during the drying process of peat in pneumatic steam plants of briquette factories.
Дл этого в блок избирательности дополнительно ввод т сигнал по температуре отработавшего теплоносител .For this, a signal on the temperature of the spent coolant is additionally input to the selectivity unit.
На чертеже схема1тически изображено устройство, реализующее предлагаеквлй способ.The drawing schematically shows a device that implements the proposed method.
Устройство содержит сушилку 1, бункер 2 с механизмом 3 изменени подачи исходного материала, пресс 4 с установленным на его выходе датчиком 5 ..ажности высушенного материгьла, механизм 6 подачи теплоносител , датчик 7 температуры воздуха на выходе кз сушилки , задатчики 8 н 9, соответственно температуры и влажности, блок 10 сравнени регул тора температуры и блок 11 избирательности.The device contains a dryer 1, a hopper 2 with a mechanism 3 changes the supply of source material, a press 4 with a sensor 5 installed at its outlet. Dried matter of matter, a heat carrier supply mechanism 6, a sensor 7 of the air temperature at the outlet of the dryer, setpoint n 8, 9, respectively temperature and humidity, a unit 10 for comparing the temperature controller and a unit 11 for selectivity.
Предлагав в11й способ автоматического регулировани Осуществл етс следунздим образом.By offering a 11th method of automatic control. It is carried out in the following way.
В блок 11избирательности через регул т«ч т«в«1вратуры ввод т сигнал ковечиой влажности высушенного материала . Блок 11, исход из заложенного алгсфвтма, с«1редел ет вид регулирующего воздействи : либо осуществл ет изменение подачи исходного материала при псмощн механизма 3, либо измен ет подачу теплоносител при помощи механизма 6. Дополнительно в блок 11 избирательности ввод т сигнал по температуре воздуха на выходе из сушилки, измер емой датчиком 7.In the selectivity unit 11, the signal of the dried moisture from the bucket moisture is entered through the "h t" in the "1 gate". Unit 11, based on the pledged algorithm, determines the type of regulating effect: either it changes the supply of the source material with the power mechanism 3, or it changes the coolant supply with the help of mechanism 6. Additionally, in the selectivity unit 11, the signal on air temperature is entered the outlet of the dryer, measured by the sensor 7.
Применение предлагаемого способа в технологическом процессе торфобрикетного производства позвол ет увеличить производительность завода, повысить экономичность сушки, улучшить качество торф ных брикетов и облегчить труд обслуживающего персонала.The application of the proposed method in the process of peat briquette production allows to increase the plant's productivity, improve the drying efficiency, improve the quality of peat briquettes and facilitate the work of service personnel.
