Description
Изобретение относитс к отбору проб сыпучих материалов из потока, точнее к устройствам дл автоматического отбора из потока проб угл и продуктов его обогащени и определени их свойств, и может быть использовано в угольной, металлургической , строительной и химической промышленност х.The invention relates to sampling bulk materials from a stream, more precisely to devices for automatically taking coal and its enrichment products from a stream and determining their properties, and can be used in the coal, metallurgical, construction and chemical industries.
Известно устройство дл отбора проб угл и продуктов его обогащени , содержащее механизм отбора проб, расходный бункер с впускным затвором, реверсивный механизм перемещени пробы. Подключенный к одному из; выходов блока управлени , другие выходы которого св заны соответственно с реверсивным механизмом перемещени пробы, механизмом отбора пробы и прибором дл определени свойств материала, и задатчик числа порций, соединенный с одним из входов блока управлени tl.A device for sampling coal and its enrichment products is known, comprising a sampling mechanism, a feed bin with an inlet gate, a reversing mechanism for moving the sample. Connected to one of; the outputs of the control unit, the other outputs of which are associated respectively with the reversible sample transfer mechanism, the sampling mechanism and the device for determining material properties, and the unit number control unit connected to one of the inputs of the control unit tl.
Недостатком известного устройства вл етс низкое качество отбираемой пробы, обусловленное погрешностью дозировани , которое осуществл етс по сигналу весоизмерител . При недостатке пробы приходитс дополн ть новой дозой, а дополнитель-но отобранный материал, смаоанмый с ранее отобранным, снижает точность определени свойств опробываемого материала ,A disadvantage of the known device is the low quality of the sampled sample, due to the dosing accuracy, which is carried out at the signal of the weight gauge. With a shortage of samples, a new dose is added, and additionally selected material, matched with previously selected, reduces the accuracy of determining the properties of the material being tested,
Цель изобретени - повышение, качества отбираемой пробы за счет по вьниени точности дозировани .The purpose of the invention is to improve the quality of the sample taken due to the accuracy of dosing.
Указанна цель достигаетс тем, что устройство дополнительно содер10 жит датчик уровн , установленный в расходном бункере и подключенный к соответствующему входу блока управлени , а впускной затвор выпол ей в виде мерной дозировочной емкости, This goal is achieved by the fact that the device additionally contains a level sensor installed in the feed bin and connected to the corresponding input of the control unit, and the inlet valve is in the form of a metering dosing tank,
15 при этом реверсивный механизм перемещени пробы кинематически св зан с мерной дозировочной емкостью.15, wherein the reversing movement of the sample is kinematically associated with the metering capacity.
На чертеже представлена схема The drawing shows the scheme
20 1 устройства.20 1 devices.
Устройство состоит из механизма отбора пробы 1 с приводом 2, расходного бункера 3, датчика уровн 4, впускного затвора устройства, сос25 . то щего из реверсивного механизма 5 .перемещени пробы и мерной дозировочной емконсти 6, прибора 7 дл определени свойств материала, блока 8 управлени и задатчика 9 числа The device consists of a sampling mechanism 1 with drive 2, feed hopper 3, level sensor 4, inlet gate of the device, ac25. from the reversing mechanism 5. movement of the sample and measuring dosing capacity 6, the device 7 for determining the properties of the material, control unit 8 and unit number 9
