Description
The utility model relates to a kind of ripple or particle radiation of utilizing and tests or the employed device of instrument of analysis of material a kind of monitoring device of using the quick ash content of coal instrument of gamma-ray measurement ash value of more specifically saying so.
The ash content of coal value is the key technical indexes of Coal Quality, heating value of coal there is direct influence, adopting quick ash content of coal only to measure the ash content of coal value is a kind of more advanced means, the ash content of coal instrument generally is made up of monitoring device and measurement controller etc. fast, and described monitoring device then mainly comprises source compartment, detector and coal sample bucket whirligig etc.In the prior art, described coal sample bucket whirligig can only horizontally rotate, promptly belong to this kind structure as Chinese patent 93240260.7, the shortcoming of this existing device is: when beam is worn the coal sample of penetrating the coal sample bucket when going to measure its ash value, because the coal sample bucket only horizontally rotates, low profile ash value of energy measurement only, and coal is along viscosity, ature of coal difference, so its distribution is uneven, it is little to measure a low profile volume, representative poor, deviation is big.
The utility model is to overcome the shortcoming of above-mentioned prior art and provides a kind of Ash analyser that makes to measure a plurality of positions, makes the quick ash content of coal monitoring device only that the measurement result representativeness is good, deviation is little, precision is high.
For finishing above-mentioned purpose, technical solution provided by the utility model is, a kind of monitoring device of quick ash content of coal instrument, comprise: frame 1, the source compartment 2 that has collimating aperture 3, front end has the detector 7 of collimating apparatus 6 and the coal sample bucket whirligig 4 between described source compartment 2 and detector 7, described coal sample bucket whirligig 4 comprises vertical shaft 11, be positioned at the pallet 8 of vertical shaft 11 upper ends, be installed in the follower gear 21 on the vertical shaft 11, be installed in and horizontally rotate drive motor 16 on the frame 1, its special character is, connect a major axis gear 15 on the output shaft of described motor 16, this major axis gear 15 is meshed with described follower gear 21, described vertical shaft 11 outsides are provided with a lifting cover 9, this lifting cover 9 is positioned at a fixed cover 13 that is installed on the frame 1, and described vertical shaft 11 lower ends are connected on the jacking gear.
Can install between 10, two bearings 10 of two bearings between vertical shaft 11 described in the above-mentioned technical solution and the lifting cover 9 vertical shaft sleeve 12 is set.Can reduce vertical shaft 11 like this and overlap the friction force when doing relative rotation between 9 with lifting.
Jacking gear described in the above-mentioned technical solution can be by lifting ratch 17, with this lifting tooth 17 on transverse teeth pinion in mesh 20 and the small machine 19 that is used for driving pinion 20 constitute, described small machine 19 is installed on the frame 1, and the lower end of described vertical shaft 11 is connected on the lifting ratch 17.Described jacking gear can also be to constitute by friction wheel, friction bar and clutch coupling thereof or by the female wheel of snail, the female bar of snail and clutch coupling thereof.
The advantage that the utility model is had compared to existing technology is: it not only can make the coal sample bucket horizontally rotate, also can make vertical lifting action, so just can make Ash analyser as requested energy measurement to the ash content of coal value of a plurality of positions, thereby make the representative good of measurement result, deviation is little, the precision height.
The accompanying drawing drawing is described as follows:
Fig. 1 is the structural representation of a preferred embodiment of the utility model;
Fig. 2 is the structural representation of coal sample bucket whirligig 4 in the preferred embodiment.
Being described as follows of each label among the figure: 1-frame 2-source compartment 3-collimating aperture 4-coal sample bucket whirligig 5-coal sample bucket 6-collimating apparatus 7-detector 8-pallet 9-lifting cover 10-bearing 11-vertical shaft 12-vertical shaft sleeve 13-fixed cover 14-index dial 15-major axis gear 16-motor 17-lifting ratch 18-chuck 19-small machine 20-pinion wheel 21-follower gear
Know referring to Fig. 1, the monitoring device of this quick ash content of coal instrument has a frame 1, the source compartment 2, the front end that are provided with collimating aperture 3 on it have the detector 7 of collimating apparatus 6 and the coal sample bucket whirligig 4 between described source compartment 2 and detector 7, place a coal sample bucket 5 on the described coal sample bucket whirligig 4.
Referring to Fig. 2, this coal sample bucket whirligig 4 comprises vertical shaft 11, pallet 8 is installed in the upper end of vertical shaft 11, the outside of vertical shaft 11 is provided with a lifting cover 9, be provided with two bearings 10 between vertical shaft 11 and the lifting cover 9, a vertical shaft sleeve 12 is set between the two bearings 10, described lifting cover 9 is installed in the fixed cover 13, fixed cover 13 is connected on the frame 1, follower gear 21 is installed on the vertical shaft 11, and be meshed with major axis gear 15, major axis gear 15 is driven by the drive motor 16 that horizontally rotates that is installed on the frame 1, index dial 14 is installed in major axis gear 15 upper ends, is used to control the angle of pallet 8 rotations, and the lower end of described vertical shaft 11 is connected on the jacking gear, this device is by lifting ratch 17, with the horizontal cross tooth pinion in mesh 20 on this lifting ratch 17, and the small machine at a slow speed 19 that is used for driving pinion 20 constitutes, this small machine 19 is installed on the frame 1, and the lower end of described vertical shaft 11 is connected on the lifting ratch 17, and the lower end of lifting ratch 17 is positioned at chuck 18.
