Fig. 2 is the miniature oil plant naphthaometer of a utility model sample cup inner structure synoptic diagram;
Fig. 3 is the circuit block diagram of the miniature oil plant naphthaometer of the utility model.
Embodiment
For further setting forth the utility model, do more detailed explanation below in conjunction with embodiment.
Present embodiment is made up of sample cup 1, well heater 2, arc ignition electrode 3, scintillation detector probe 4, temperature sensor 7 and interlock circuit, sample cup 1 is put into the 3-5ml tested sample, put on well heater 2 and sealing, under the control of respective actuators circuit, sample in the cup is heated, when reaching uniform temperature, light the ignition mixed gas by arc ignition electrode 3, scintillation detector probe 4 is sent flash fire signal at this moment into MCU, and the temperature value during simultaneous temperature sensor 7 record scintillations is finished test.
Fig. 1 is the complete machine panel synoptic diagram of present embodiment, sees at casing 10 upper surfaces that from appearance sample cup 1, display 11 and keyboard 12 are arranged.Certainly this is not unique layout, shows to be a kind of arrangement mode among the figure.
The cut-open view of sample cup 1 is seen Fig. 2, and sample cup 1 has well heater 2, and well heater 2 also can be made the respective cups type, wraps in outside the sample cup 1; Wall of cup is provided with arc ignition electrode 3, scintillation detector probe 4 and temperature sensor 7; In order to keep temperature, energy efficient, the outer muff 8 that is surrounded by of cup; For reaching sealing, flap 5 with matching is arranged on the rim of a cup 6, this flap 5 is connected with rim of a cup 6, can adopt thread forms, also can adopt the form of buckle fastening, will reach sealing effectiveness in a word.
Sample cup 1 is connected with casing 10 by shock structure 9; for each parts that stretches out the sample cup 1 outside the casing 10; establish specially with protective cover 14; this protective cover 14 can be raised in use; the time spent does not close; with buckle 15 lockings, in case in carrying the way, damage arc ignition electrode 3, scintillation detector probe 4, the temperature sensor 7 on the sample cup 1 and be connected electric wire.
As Fig. 3, shown in Figure 1, be equipped with in the utility model machine and detect control circuit 18, form by scintillation testing circuit, arc ignition circuit, temperature control circuit, executive circuit and MCU, the output of MCU is connected respectively to arc ignition circuit, temperature control circuit and scintillation testing circuit through executive circuit, and detected flash fire signal of scintillation testing circuit and the detected temperature data of temperature control circuit are then directly sent into MCU.Detect control circuit and sample cup 1 part and separately settle, the temperature of avoiding well heater is to detecting the influence of control circuit.The output that detects control circuit 18 connects the R232 interface, in order to be connected with computing machine; The switch 17 that detects control circuit 18 is located at the back of casing 10.Just signal among the figure detects control circuit board 18 and poises, and this wiring board is on the support that is fixed in the casing 10 in the reality.
