Fully automatic fluorine chlorine measuring instrument

Abstract

The invention discloses a fully automatic fluorine chlorine measuring instrument which comprises a hydrolysis part and a titration part. The hydrolysis part is divided into a power supply switch, an indicator light, a liquid crystal touch screen, hydrolysis tubes, an air inlet, a sample feeding rod, a sample feeding upright tube, a flow meter, a steam inlet, a sample feeding mechanism, a barometer, an oxygen cylinder, a heating furnace module and a control mainboard. The titration part includes a peristaltic pump, a fluoride ion electrode, a chloride ion electrode and a peristaltic tube. Two hydrolysis tubes are arranged on the side of the hydrolysis part of the measuring instrument. The air inlet and the steam inlet are arranged on both sides of the hydrolysis tubes. The measuring instrument is designed based on a high frequency induction electric furnace method. For an original technology, the manual workload is large, and one sample is made at a time, which is time consuming and laborious. According to the measuring instrument, two samples can be fed in at a time, and two samples are made in the same time. The measuring instrument has the advantages of simple operation, less interference ions, short measurement time and accurate measurement result.

Description

technical field [0001] The invention relates to the field of coal quality analysis and testing, in particular to an automatic fluorine and chlorine measuring instrument. Background technique [0002] Most of the existing sample delivery is manual sample delivery, manually sealing the rubber plug, and sending one sample at a time. The manual operation is cumbersome, and the error of sampling and sample preparation is much greater than the error of the test. It is the most prone to human errors. , poor safety, manual titration, cumbersome calculations, and most of today’s instruments have good stability in the initial stage. After a period of use, due to the contamination of sensors or pipelines, the water filling becomes unstable, which makes the measurement results very unstable. big error. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic fluorine and chlorine measuring instrument for the above probl...
