DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a calorific value measuring apparatus in which a sample is sealed in a bomb together with oxygen gas and burned in water.

[0002]

2. Description of the Related Art A conventional calorific value measuring device of the type described above comprises:
Seal the sample into a bomb with an opening at the top as specified in JIS M 8814, close the screw-type lid, inject high-pressure oxygen into the bomb, and then remove the bomb from the tank for calorific value measurement. After setting inside, the ignition wire was connected to the electrode rod, and the lid of the calorific value measurement water tank was closed to perform the measurement.

However, in such a conventional calorific value measuring device, since the opening of the bomb is located at the upper part, it is necessary to turn the bomb upside down to clean the inside each time one measurement is performed. Since the electrode rod penetrating the lid is also at the top of the bomb, the wires must be drawn out through the multiple lids of the calorific value measurement water tank, which makes the operation complicated and the structure of the calorific value measurement water tank lid complicated. Had become something. Therefore, it has conventionally been difficult to automatically measure the calorific value.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the illustrated embodiments. FIG. 1 shows the entire calorific value measuring apparatus of the embodiment, wherein 1 is a calorific value measuring water tank provided with a lid 2 which can be automatically opened and closed, and 3 is a lid provided at a position adjacent to the calorific value measuring water tank 1. The closing device 4 is a cleaning tank. Reference numeral 5 denotes a bomb. The bomb 5 is cleaned in the cleaning tank 4 by an automatic transfer device 7 having a robot hand 6 provided above the bomb, and the lid closing device 3 performs sample filling and oxygen filling.
The calorific value is measured in the calorific value measuring water tank 1. The above layout is not an essential requirement of the present invention.

The conventional bomb has a screw-type lid at the upper end, but the bomb 5 used in the present invention has a bell-like shape having an opening facing downward and a lid 8 on the lower side as shown in FIG. belongs to. The lid 8 is provided with a pair of electrode rods 9 for igniting the sample stored inside. A projection 10 is formed at the upper end of the bomb 5 to facilitate chucking by the robot hand 6.

FIG. 3 shows an internal structure of the calorific value measuring water tank 1, wherein 11 is an outer tank, 12 is an intermediate tank, and 13 is an inner tank. An electrode 14 is provided on the inner bottom of the inner tank 13 so as to face the electrode rod 9 of the bomb 5. When the bomb 5 is set inside the inner tank 13 as shown in FIG. 9
Is in contact with the upper end surface of the electrode 14 so that electricity can flow.

FIGS. 4 and 5 show an example of the arrangement of the electrodes 14, in which two electrodes 14 and one holder 15 are arranged at 120 ° intervals. In this case, if the tip of the electrode rod 9 is sharpened as shown in FIG. 5 and the upper end of the corresponding electrode 14 is formed in a concave shape, the positioning of the two can be performed accurately and easily. The two electrodes 14 and the holding table 15 are
The arrangement at 0 ° intervals is because this arrangement has the highest stability.

FIG. 6 and FIG. 7 show another example of the arrangement of the electrodes 14, in which one of the electrodes 14 and two
In addition to the arrangement at 0 ° intervals, another electrode 14 is arranged at a position symmetrical with respect to each center O. In this case, as shown in FIG.
It is preferable that a structure be adopted in which the spring can be expanded and contracted by a spring 16 so that the other electrode 14 can be reliably energized.

As shown in FIG. 3, a thermocouple thermometer 17 and a propeller 18 for stirring are installed in the inner tank 13. The stirring propeller 18 may be externally rotated by a motor, but as shown in FIG. 8, the lower end of the propeller 18 is inserted into a fixed driving unit 19, and the driving unit 19 generates a rotating magnetic field to generate electromagnetic force. If the propeller 18 is rotated by force, water leakage from the rotating part can be completely prevented.

[0012]

According to the calorific value measuring apparatus of the present invention thus constructed , the protrusion 10 at the upper end of the bomb 5 is chucked by the automatic transfer device 7 having the robot hand 6 as described above.
First, the bomb 5 is washed in the washing tank 4, the sample is enclosed and oxygen is filled in the lid closing device 3, and the calorific value is measured in the calorific value measuring water tank 1. In this case, since the opening of the bomb 5 is directed downward in the present invention, it is necessary to insert the cleaning nozzle 20 into the inside of the cleaning tank 4 as it is as shown in FIG. And the drainage of the washing water is performed naturally.

After the cleaning of the interior is completed, the bomb 5 is transferred to the lid closing device 3 to close the lid 8, and is filled with high-pressure oxygen and set in the calorific value measuring water tank 1. At this time, as shown in FIG.
Since the electrode 14 is provided at the bottom of the inner tank 13 so as to face the electrode rod 9 on the lid 8 side of the bomb 5, the electrode rod 9 and the electrode 14 are brought into contact by simply setting the bomb 5 at a predetermined position. Thus, energization can be performed. Therefore, in the calorific value measuring device of the present invention, it is not necessary to draw out a current-carrying wire above the bomb 5, and the structure of the lid of the calorific value measuring water tank 1 can be simplified.

[0014]

As described above in detail, according to the present invention, the opening of the bomb is directed downward, and the electrode is provided at the bottom of the calorific value measuring water tank so as to face the electrode bar. , to allow easy current supply to the washing and electrodes bomb, also the structure of the lid of the calorific value measuring tanks from those that could be simplified, the amount of heat to solve the conventional problems As a measuring device, it greatly contributes to industrial development.
