Description
Technical field
The utility model relates to hazardous chemical checkout equipment technical field, particularly the full-automatic spontaneous ignition temperature determinator of one.
Background technology
The temperature control process of existing spontaneous ignition temperature analyzer is substantially all that employing three thermopairs measure flask neck, middle part and bottom temp respectively, judges whether spontaneous ignition temperature analyzer is stabilized in target temperature by the temperature of three thermocouple measurements.But due to the flask in heating furnace and be air between heating furnace wall, and air rate of heat transfer is comparatively slow, causes spontaneous ignition temperature analyzer needs just can be stabilized to target temperature for a long time.
Because air rate of heat transfer is slower, when flask temperature reaches target temperature first, oven wall surface temperature far exceedes target temperature, although now heating furnace stops heating, heating furnace wall waste heat can continue heating flask and make flask temperature exceed target temperature.Afterwards due to thermolysis, heating furnace and flask temperature can decline, but oven wall surface temperature decline rate is faster than flask temperature decline rate, cause flask temperature lower than oven wall surface temperature during target temperature far below target temperature.So flask temperature can level off to target temperature in vibrating type, and this process need for a long time.
Utility model content
In order to solve the deficiency of above-mentioned prior art, the purpose of this utility model is: provide a kind of full-automatic spontaneous ignition temperature determinator.
A kind of full-automatic spontaneous ignition temperature determinator, comprise cylinder shell, along the radial direction of described cylinder shell, from its inwall wherein the heart be disposed with heat-insulation layer, heater strip, and cylindric heating furnace, described cylinder shell edge of opening is provided with ring cover, wherein, micro-adjusting mechanism is set bottom described ring cover; Described micro-adjusting mechanism comprises and is separately positioned on micromachine bottom described ring cover and suspension rod, the cam driving-rod coaxial with described Miniature electric machine output shaft, be arranged on the cylindrical sleeve of described suspension rod free end, the guiding fixed cover be slidably matched with described sleeve, thermopair is provided with in described guiding fixed cover, its top, one end is provided with handstand " U " type slide fastener, and described cam driving-rod one end is provided with the guide pole that to be interlocked with described slide fastener.
Described suspension rod is non-removable being fixedly connected with described ring cover bottom surface.
Described cam driving-rod one end is fixed on the output shaft of described micromachine, and the other end connects guide pole.
The internal diameter of described sleeve is slightly larger than the external diameter of described guiding fixed cover.
