Description of the Related Art In a spontaneous ignition test apparatus, as shown in FIG. 3, a case 2 is placed on an operation panel box 1 and a sample holder 3 holding a sample on the case 2 is provided. It has a structure to be inserted. Then, the temperature around the sample held in the sample holder-3 is raised to a constant value, and the time until spontaneous ignition is measured. The sample holder-3 is
As shown in FIG. 4, the sample 6 is placed on the sample holder 4 below the ventilation pipe 5 provided with the gas flow path 5a communicating with the outside, and the inside is filled with an inert gas (N 2 , Ar, He, etc.). In this state, the heater 8 is heated to maintain the surroundings of the sample 6 at a constant temperature (hold), and the time until spontaneous combustion is measured. In the lower part of the sample holder-3, a mechanism for switching the inert gas discharged from the plug 7 to air or oxygen in a constant temperature hold state is incorporated. When the sample 6 is exposed to oxygen from an inert gas in a state of being held at a constant temperature, it causes an oxidation reaction to gradually raise the temperature of its surroundings and finally ignites. In this case, it is desirable that the sample 6 be exposed to the inflowing gas as uniformly as possible, and therefore the gas outlet 9 is provided above the ventilation pipe 5 of the sample holder-3.

上昇するまでの時間Ｈを測定するのが普通である。The spontaneous ignition device measures a sample that ignites by itself (measures the time from constant temperature to ignition), but normally does not actually ignite it. When the sample approaches the ignition state, its temperature rises rapidly. That is, as shown in FIG. 5, the sample is heated to a constant temperature and held (maintained), and when the constant temperature elapses, the temperature rapidly rises, but the measurement is held at this constant temperature. It is usual to measure the time H from when the temperature rises to a sharp rise.

という問題があった。The device is equipped with an ignition prevention mechanism because it is dangerous if the sample is actually ignited and the device may be damaged. This ignition prevention mechanism is a mechanism that stops the inflow of air (oxygen) and rapidly releases an inert gas (N 2 , Ar, He, etc.) when the temperature reaches a certain temperature. When there is no oxygen around the sample, the sample stops the oxidation reaction and does not ignite. Also,
The rapid release of the inert gas is also considered to have the effect of rapidly lowering the ambient temperature. However, the conventional device has a problem that the sample is blown out from the gas outlet 9 in the case of the powdery sample.

As shown in this figure, the bottom surface 4a of the sample holder 4 on which the sample 6 is placed has small holes 4b, 4b, ... In order that the sample 6 does not drop and air (oxygen) or an inert gas can flow in. Many are provided. A small mesh mesh cover 16 is installed at the inlet of the gas flow passage 5a of the ventilation pipe 5 above the sample 6 placed on the sample holder 4. This mesh cover 16 is a sample holder 4
This is for preventing gas from being blown out from the holes 4b, 4b, ... Provided on the bottom surface of the sample 6 so that the sample 6 does not enter the gas flow passage 5a of the aeration tube 5.

These exhaust ports 17 and 18 are used for the gas flow passage 5a of the ventilation pipe 5.
When the mesh cover 16 provided at the inlet of the sample is clogged, the gas goes out of the support 13 outside the sample holder 4 and out of the space 2a in the case 2 as shown by the arrow in FIG. It is a hole for leading to the gas outlet 9.

ない。The exhaust ports 17 and 18 should be as small holes as possible. That is, these exhaust ports 17,
If 18 is too large, plug 7 due to oxidation reaction during measurement.
The more inflowing gas passes through the inner space 2a of the case 2 and is exhausted from these exhaust ports 17 and 18, so that the sample 6
This is because there is a problem that the gas is not sufficiently exposed to. On the contrary, when the exhaust ports 17 and 18 are small, the pressure inside the furnace rises because the gas is not sufficiently discharged when a large amount of gas flows out in the ignition prevention stage. Therefore, there is no particular problem because the volume of the internal space 2a is sufficiently large and the time required for flowing a large amount of gas is short.

る。The spontaneous ignition test apparatus of the present invention has the above-mentioned structure, and its operation will be described below. (1) Place the sample 6 on the sample holder 4 and discharge the inert gas (N 2 , Ar, He, etc.) from the plug 7 to fill the periphery of the sample 6 and the entire sample holder-3 is predetermined by the heater 10. After the temperature is reached, the heater 8 is turned on to hold the sample at a constant temperature, for example 100 ° C. (2) Then, the gas discharged from the plug 7 is switched from an inert gas to air (oxygen), and when the temperature stabilizes, the time measurement is started. At the time of measurement, the inflowing gas is discharged from both the conventional flow path passing through the holes 4b, 4b, ... On the bottom surface of the sample holder 4 and passing through the sample 6 portion, and the exhaust ports 17 and 18. Since the holes 17 and 18 have sufficiently small hole diameters, a sufficient amount of gas (air) can flow through the sample 6. (3) After a predetermined time, when the temperature starts to rise rapidly, the gas discharged from the plug 7 is rapidly switched from the air (oxygen) to the inert gas. (4) At this time, when the ignition prevention mechanism works, when a large amount of gas flows in, the sample tries to be ejected from the flow passage 5a, but is blocked by the mesh cover 16. (5) When the mesh cover 16 is clogged, the gas is discharged mainly through the vents 17 and 18.

In addition, a pressure regulating valve or a solenoid valve 20 (see FIG. 1) may be provided on the upper wall of the case 2. That is, when the ignition prevention mechanism operates, this pressure regulating valve or solenoid valve 20
May act. In this case, since the air (oxygen) around the sample 6 needs to be removed in order to suppress the reaction (ignition) of the sample 6, the pressure regulating valve or the solenoid valve 20 does not act simultaneously with the ignition prevention mechanism (gas switching mechanism). , 1 to 2 seconds must be delayed.
