Abstract
The invention discloses a moisture tester crucible which comprises a crucible base body and further comprises a metal layer covered on the surface of the crucible base body. Due to the fact that the metal layer is arranged on the surface of the crucible base body and basically guides static on the crucible base body away, the crucible completely resolves the problem of inaccuracy experiment results of a moisture tester caused by effects of static in winter in the northern area. The crucible further improves accuracy of experiment results and can accurately reflect real moisture content of coal samples to be tested. The crucible prolongs service life by arranging the metal layer on the surface of the crucible base body, removes mental stress of chemical analysts in use of instruments and reduces purchase cost of parts easy to damage of a using unit more importantly. The moisture tester crucible is a metal crucible.
Description
Technical field
The present invention relates to the moisture tester technical field, more particularly, relate to a kind of moisture tester crucible.
Background technology
In coal analysis instrument series of products; In order to measure the content of moisture in the coal sample; The weight that at first needs the empty ceramic crucible of weighing is put into the tested coal sample weight that GB is stipulated then, through the heating of moisture tester heating arrangement; The temperature of moisture tester is reached (105-110) ℃, the moisture in the tested like this coal sample is with regard to rapid evaporation; And then weighing crucible and tested coal sample is residual heavy, and the weight that coal sample reduces multiply by very divided by the weight of tested coal sample, thereby calculates the content of its moisture.
The crucible that moisture tester was equipped with of present whole ature of coal industry all adopts ceramic crucible; And ceramic crucible is placed on the rotating disk of moisture tester (rotating disk and the earth conducting); In the north because the winter climate drying is added laboratory heating gas causes and exist a lot of free electrostatic ionics (when in a single day a lot of northerly moisture testers go into heat supply in winter in the air of laboratory; The experimental result accuracy is just low; Even collimation is overproof, but the experimental result accuracy of doing other season is all very high.Through a large amount of experiments, discovery is that crucible has static, and phenomenon is significantly: hand is run into crucible has static " whip " sound; Sometimes produce electric spark), be easy to attached on the ceramic crucible surface, pottery is the good insulation performance body; Can not static led away through rotating disk or discharged, after in a single day crucible was with static, electrostatic ionic be not to be evenly distributed on the ceramic crucible; But concentration of local (we once tested and proved: increase the metal hairbrush; Static can be led away on sending out crucible existing, and what have does not lead away at all, because the metal hairbrush can only brush a fixed position of crucible at every turn.The crucible that we are not led away static, through with hand it being carried out omnibearing touch, static is promptly led away).On earth at crucible surface where static be difficult to confirm (because static is can't see, and being at random when adhering to).Therefore, when weighing sky ceramic crucible, electrostatic adhesion (the airborne molecule of Electrostatic Absorption) is on crucible; Cause himself Heavy Weight of crucible weight ratio, when putting the coal sample weighing, crucible surface has the possibility of Electrostatic Absorption once more; The actual weight that causes coal sample than weighing show in light weight; Yet in heating process, water evaporates simultaneously static receives the influence that local environment humidity reduces, the static part that can disappear; In the time of the residual heavy and result of calculation of last weighing coal sample, receive the influence of above-mentioned static factor, the result is just extremely inaccurate (because moisture tester is an exact instrument; The weighing balance all be accurate to ten thousand/, crucible weight is received that external interference changes and is surpassed at 10/10000ths o'clock that the result is just inaccurate; Static is to the influence of ceramic crucible weight; Once found in the experiment to have much 200/10000ths influence most, therefore, the result is at sixes and sevens not hard to imagine).
In sum, the moisture tester of present whole industry all is equipped with ceramic crucible, all has following problem:
1, moisture tester in the north because the winter climate drying is added laboratory heating gas causes and exist a lot of free electrostatic ionics to cause the Moisture Meter experimental result to be forbidden attached to the ceramic crucible surface in the air of laboratory.
2, tackle the way of static at present: when the lab technician tests, all must carry out 2 (claim before the empty crucible with claim coal sample before) comprehensive touches to crucible with hand at every turn, a bit touch not in placely if having, static discharges not just thoroughly, and test findings is just inaccurate.
3, moisture tester uses the ceramic crucible test findings bigger than the baking oven test findings difference of arbitration, can not reflect the moisture of tested coal sample really.
4, the moisture tester maximum temperature is 110 ℃, and ceramic crucible generally uses in the hot environment more than 900 ℃, is a kind of waste of serious resource therefore.
5, ceramic crucible is a breakable member, and annual applying unit all can be purchased ceramic crucible in a large number, falls on the ground ceramic crucible because of carelessness and breaks phenomenon into pieces because the lab technician is often taken place, invisible psychological pressure that increases the laboratory personnel.
Therefore, how to avoid becoming the technical matters that those skilled in the art need to be resolved hurrily because there is the defective of the test data error of bringing in static.
Summary of the invention
In view of this, the invention provides a kind of moisture tester crucible, to avoid existing the defective of the test data error of bringing owing to static.
For realizing above-mentioned purpose, the present invention provides following technical scheme:
