Изобретение относитс к спектральному анализу порошков, преимущественно горных пород, минералов, концентратов.This invention relates to the spectral analysis of powders, mainly rocks, minerals, and concentrates.
В известных дозируюп их устройствах дл введени порошкообразных проб в спектрально-аналитический прибор, содержаш,их блок подачи порошков, дозируюш:ую воронку с клапаном и штуцер пневмоочистки, не решена задача пневмоочистки от загр знени остатками предыдущего анализируемого порошка дозирующей воронки.In the known dosing devices for introducing powdered samples into a spectral analytical device, containing their powder supply unit, dosing: a funnel with a valve and a pneumatic cleaning nozzle, the problem of pneumatic cleaning from contamination by residues of the previous analyzed dosing powder is not solved.
Цель изобретени - интенсификаци пневмоочистки .The purpose of the invention is to intensify the pneumatic purification.
Это достигаетс тем, что в предлагаемом устройстве штуцер пневмоочистки установлен на боковой поверхности воронки, а клапан выполнен в виде лепестка на шарнире.This is achieved by the fact that in the proposed device a pneumatic cleaning choke is installed on the side surface of the funnel, and the valve is designed as a petal on a hinge.
На чертеже схематически представлено предлагаемое устройство.The drawing schematically shows the proposed device.
Анализируема порошкообразна проба 1 периодически засыпаетс с помощью блока 2 подачи порошков в дозирующую воронку 3 и поступает в спектрально-аналитический прибор . В режиме пневмоочистки включаетс электропривод В1нешней воздуходувки, соединенной с баковым штуцером 4 лиевмоочистки; струей воздуха через штуцер лепесток клапана 5 отбрасываетс , последний поворачиваетс вокруг шарнирной оси к закраинам широкой части дозирующей воронки и запирает ее изнутри избыточным давлением воздуха в воронке , в результате чего создаетс интенсивный поток воздуха через сужение воронки 3, увлекающий остатки анализируемого порошка в выт жную систему.The analyzed powder sample 1 is periodically filled with the aid of the powder supply unit 2 into the metering funnel 3 and is fed to a spectral analysis instrument. In the air cleaning mode, the electric drive B1 of the external blower is connected, connected to the tank fitting 4 of the cleaning unit; the air flap 5 is rejected by a stream of air through the nozzle, the latter turns around the hinge axis to the edges of the wide part of the metering funnel and locks it from inside with excessive air pressure in the funnel, resulting in an intense air flow through the constriction of the funnel 3, which carries the remains of the analyzed powder into the exhaust system .
