Изобретение относитс к технике измepe НИИ, проводимых В процессах сушки.The invention relates to a technique for measuring scientific research institutes conducted in drying processes.
Известны лабораторные установки дл определени коэффициента влагопроводности зернистых материалов в процессе сушки, содержащие термостатируемую камеру с держателем дл размещени исследуемого материала и датчик влагопроводности.Laboratory installations are known for determining the moisture conductivity of granular materials during the drying process, comprising a thermostatted chamber with a holder for accommodating the material to be examined and a moisture transducer.
Однако В таких установках невозможно определить коэффициент влагопроводности зернистых материалов без нарушени их вну ренней структуры так как дл определени данного коэффициента необходимо спрессовывать материал.However, in such installations it is impossible to determine the moisture conductivity of granular materials without disturbing their internal structure, since it is necessary to compress the material to determine this coefficient.
Цель изобретени - повышение точности проводимых измерений,The purpose of the invention is to improve the accuracy of measurements,
Это достигаетс тем, что держатель выполнен В виде расположенной в сосуде с водой подставки, снабженной фитилем дл подвода влаги к исследуемому материалу, а датчик выполнен в В1эде цветомера, уста 1овленного над поставкой.This is achieved by the fact that the holder is made in the form of a stand located in a vessel with water, equipped with a wick for supplying moisture to the material under investigation, and the sensor is made in B1ade of a color meter, installed on the supply.
На чертеже схематически изображена предлагаема установка. Установка содер. жит термостат 1, психрометр 2, термометр The drawing shows schematically the proposed installation. Installation Contents there is a thermostat 1, a psychrometer 2, a thermometer
3, цветомер 4, установленный над подставкой 5 с исследуемым материалом 6, Подставка 5 размещена в сосуде 7 с водой и снабжена фитилем 8 дл подвода воды к материалу.3, a color meter 4 mounted above the stand 5 with the test material 6, the Stand 5 is placed in the water vessel 7 and provided with a wick 8 for supplying water to the material.
Наличие цветомера 4 позвол ет быстро и точно определить коэффициент влагопроводности материала без нарушени его структуры .The presence of color 4 allows you to quickly and accurately determine the moisture conductivity of a material without disturbing its structure.
Принцип работы заключаетс в следующем .The principle of operation is as follows.
Исследуемый материал 6 устанавливаетс наподставке 5 с фитилем 8; цветомер 4 устанавливаетс на нулевое деление, после чего сосуд 7 заполн етс всдой соответствующей температуры до 2/3 уровн подстав ки 5, котора зафиксирована так же, как и сосуд 7 В заданном положении. После запо;ьнени сосуда 7 водой ведетс отсчет по секундомеру времени достижени влагой npt тивоположного конца материала 6, которое фиксируетс показанием цветомера 4. Путь движени влаги известен, дл чего измер етс высота исследуемого материала 6. Зна путь и вpeм расчетным путем опредеп етс скорость движени влаги в материале . По полученным данным скорости движени влаги, пользу сь эталонным образцом , определ ют коэффициент влагопроводности материала.The test material 6 is installed in the adapter 5 with a wick 8; the color meter 4 is set to zero division, after which the vessel 7 is filled with the appropriate temperature up to 2/3 of the level of the base 5, which is fixed in the same way as the vessel 7 In a predetermined position. After the vessel 7 is filled with water, a stopwatch is read by the time the moisture reaches npt of the opposite end of material 6, which is recorded by the reading of the color indicator 4. The path of the moisture is known, for which the height of the material under study 6 is measured. moisture in the material. According to the obtained data, the speed of movement of moisture, using a reference sample, determine the coefficient of moisture conductivity of the material.
