Embodiment
It comprises urceolus 1, motor 4, automatic stirrer 5, electrode wires 6, electrode wires I 7, handle 8, lid 9, inner sensor hole 10, hand mixer 11, air inlet/outlet hold concurrently electrode 12, link slot 13, combustion wire I14, oxygen bomb support 15, combustion wire 16, oxygen bomb plug 17, Connection Block 18, inner core 19, it is characterized in that: an end of lid 9 is connected movingly with inner sensor hole 10, inner sensor hole 10 other ends are connected with urceolus 1, and lid 9 is provided with motor 4, handle 8.Described electrode wires 6 one ends are connected with motor 4, the other end is connected with Connection Block 18, and electrode wires I 7 one ends are connected with motor 4, the other end and air inlet/outlet are held concurrently, and electrode 12 is connected.Be provided with automatic stirrer 5, Connection Block 18, oxygen bomb plug 17, combustion wire 16, oxygen bomb support 15, combustion wire I 14, link slot 13, the air inlet/outlet electrode 12 of holding concurrently in the inner core 19.Oxygen bomb is made of hold concurrently electrode 12, combustion wire I 14, combustion wire 16, crucible 20 of electrode wires 6, electrode wires I7, air inlet/outlet.Below in conjunction with accompanying drawing in detail principle of work of the present utility model and the course of work are described in detail:
1, instrument preheating.With the utility model and whole annex is put in order and clean, the utility model and civil power～220V join, and the power-on switch carries out preheating.Annotate: do not open and stir switch.
2, sample compressing tablet.The thick test substance that claims on balance is pressed into sheet (can not press too tight, can not fully burn after the too tight igniting) in sheeter.After being pressed into sheet, on balance, accurately weigh again.
3, dress sample
The bullet of oxygen bomb is placed on the oxygen bomb support 15, test substance is put into crucible 20, crucible 20 is placed on the burning rack.Get a combustion wire and measure its length, then the combustion wire two ends are separately fixed on two electrodes, the middle part is adjacent to test substance.
4, oxygen bomb oxygenating
Use high-pressure cylinder must strictly observe working rule.Beginning is filled with first a small amount of oxygen, then opens outlet, so as to driving the air in the oxygen bomb out of.Applying about 2Mpa pressure inflates to oxygen bomb again.
5, regulate water temperature
