Description
Известен прибор дл высушивани пробы воздухонроницаемых материалов при определении их влажности весовым способом, включающий в себ сушильную камеру, через которую продувают нагретый воздух.A device for drying samples of air-permeable materials is known when determining their moisture by weight method, which includes a drying chamber through which heated air is blown.
В описываемом приборе по сравнению с известным осуществлена сигнализаци об окончании высушивани по достижении равенства температуры воздуха, поступающего в камеру и выход щего из нее.In the described device, as compared with the known one, a signaling about the end of drying was carried out when the temperature of the air entering and leaving the chamber was equal.
С этой целью прибор снабжен сменной кассетой дл пробы материала , устанавливаемой поперек камеры, и помещенными по обе ее стороны контактными термометрами, контакты которых настраивают на температуру воздуха, поступающего в камеру, и включают в цепь сигнального устройства.To this end, the device is equipped with a removable cassette for sample material installed across the chamber, and placed on both sides of contact thermometers, the contacts of which are set to the temperature of the air entering the chamber and included in the signaling device circuit.
На фиг. 1 изображена схема прибора; на фиг. 2-его электрическа схема.FIG. 1 shows a diagram of the device; in fig. 2nd electrical circuit.
Внутри сушильной камеры /, имеющей регулируемое отверстие 2 дл сброса влажного воздуха и регулируемое отверстие 3 дл подсоса воздуха, устанавливаетс поперечна сменна кассета 4 с пробой высушиваемого воздухопроницаемого материала.Inside the drying chamber / having an adjustable opening 2 for discharge of moist air and an adjustable opening 3 for air leaks, a transverse exchangeable cartridge 4 is installed with a sample of the dried air-permeable material.
В верхней части камеры монтированы электродвигатель 5 с центробежным вентил тором 6 и электрический калорифер 7. На пути движени продуваемого через камеру нагретого воздуха установлены ртутно-контактный термометр 5, расположенный перед кассетой и ртутноконтактный термометр 9, наход щийс но другую сторону кассеты перед направл ющей воронкой 10.An electric motor 5 with a centrifugal fan 6 and an electric heater 7 are mounted in the upper part of the chamber. A mercury contact thermometer 5 located in front of the cassette and a mercury contact thermometer 9 located on the other side of the cartridge in front of the guide funnel are installed in the path of the heated air blown through the chamber. ten.
После включени пакетного выключател 11 нажимают кнопку 12 включени , при этом магнитные пускатели 13 и 14 соответственно включают двигатель 5 и калорифер 7.After turning on the packet switch 11, the switch-on button 12 is pressed, while the magnetic actuators 13 and 14 respectively turn on the engine 5 and the heater 7.
После того, как температура продуваемого через камеру воздуха достигает заданного значени , ртутно-контактный термометр 8 через промежуточное реле PI отключает калорифер 7, а при падении темпеAfter the temperature of the air blown through the chamber reaches a predetermined value, the mercury-contact thermometer 8 switches off the heater 7 through the intermediate relay PI, and when the temperature drops
