Description
Technical field
The utility model relates to a kind of measuring probe of coal ash content detector, particularly a kind of measuring sonde of plug-in type coal ash content detector belongs to ash content of coal fast detecting equipment technical field.
Background technology
Ash content of coal is an important parameter of weighing the coal quality.Up to now, the ash content of coal assay method of standard is to use the calcination weight method, the required time of this method long (about 60min), and present most of industrial requirements ash content of coal measurement fast, accurately, in time, therefore, this method can not satisfy industrial needs.
Utilize radiometric technique can realize the fast measuring of ash content of coal.As far back as nineteen eighty-two, Department of Engineering Physics of Tsing-Hua University has just carried out the research of " ash content of coal on-line measurement ", through the scientific research and developments in more than 20 years and achievements conversion, successively succeeded in developing " the online ash measurer of ZZ-89A type " and " the fast grey instrument of ZZ-89B type scan-type off-line ".Tsing-Hua University's Ash analyser adopts the dual energy gamma ray transmission method, by measuring two kinds of different-energy ray decay after penetrating coal, obtains pit ash, is applied to a lot of enterprises in whole nation ash content of coal fast detecting.
In the ash content of coal detection range, quick ash content detection need be carried out to vehicle-mounted coal in a lot of factories, ore deposit, adopts the intellegent sampling device to realize with the method that the fast grey instrument of ZZ-89B type scan-type off-line cooperates at present mostly.
The radioactive source of the fast grey instrument of ZZ-89B scan-type type off-line and detector are placed in the scanning rack, when detecting, the sample coal are put into the coal sample bucket, put into the scanning rack then and carry out the ash content measurement.Therefore, carrying out vehicle-mounted pit ash when measuring, must be at first to the sampling of the coal in the car, the sample that will get is given Ash analyser then, carries out ash content and measures, average per car sampling and need 10min analysis time altogether.
The weak point of above measurement mechanism is: whole measuring process needs two kinds of devices to finish, because the link of sampling and sample presentation makes Measuring Time long, this has influenced industrial speed to a great extent so that benefit.
Summary of the invention
The utility model is on the basis of the original dual intensity γ of Tsing-Hua University's Ash analyser transmission beam method ultimate principle, proposes new measuring method, and carries out the new probe component of corresponding structure design, makes it to be more suitable for vehicle-mounted coal ash content of coal fast detecting.
A kind of measuring probe of coal ash content detector, this measuring sonde (13) are one " door " type device, comprise sounding rod I (1), sounding rod II (2) and the intermediate transverse girder (3) of both sides;
Sounding rod I (1) hollow, gland (10) is arranged at top; The bottom is chamber, source (4); Chamber, source (4) is used to put radioactive source (5); Generally, emissive source (5) itself has protective device, guarantees emissive source directional transmissions or environment to external world not in use, and especially the people causes damage.Door (6) also can have been designed in chamber, the utility model source (4), and door (6) is opened and closed by electromagnet (7) control, closes the orientation direction of radioactive source when also promptly guaranteeing not need emissive source to use; Electromagnet (7) is connected with magnet control line (9);
Sounding rod II (2) hollow, top gland (11); The bottom is that probe chamber is placed with detector (8); The cable of detector (12) is connected on the external control device (17) by gland (11);
Sounding rod I (1), sounding rod II (2) and intermediate transverse girder (3) are one;
Intermediate transverse girder (3) is connected with the external structure part.
Measuring sonde is main measurement mechanism, detector and radioactive source all are installed on the measuring sonde, during measurement, the sounding rod I (2) of measuring sonde and the part of sounding rod II (2) are inserted in the coal car, measure then, and the signal that measures passed to the external control device by cable, the external control device carries out data analysis, calculate the ash parameter of grading shows to the user.
Adopting the coal ash content detector of this measuring probe of coal ash content detector to compare the main difference point with traditional Ash analyser is: the measuring sonde with particular design, this measuring probe of coal ash content detector radioactive source and detector all are placed in the sounding rod, when measuring, directly sounding rod is inserted in the compartment of coal conveyor vehicle, do not need the coal sucking-off or manually deliver to the external detection device and just can measure ash content of coal, directly to the external control device just the signal that measures,, average per car measuring process needs 5min.
Using two bar plug-in type coal ash content detectors to carry out vehicle sample ash content of coal detects, with use traditional Ash analyser to carry out the measurement of vehicle ash content of coal to compare with the intellegent sampling device, major advantage is: independent measurement, need not sampling, sample presentation process, can shorten total detection time, improve the day amount detection of single device, also can reduce operating personnel's working strength and reduce operating personnel's quantity.
