Abstract

PURPOSE:To automatically measure calorific value with high accuracy by making a gas cylinder opening downward and also sequentially moving the gas cylinder among a calorific value measuring tank, a lid opening/closing device and a cleaning tank. CONSTITUTION:Since an opening of a gas cylinder 5 is downward, a cleaning nozzle can be inserted inside to clean a cleaning tank 4 without vertically reversing the gas cylinder 5 in the tank 4. After internal cleaning is completed, the gas cylinder 5 is transferred to a lid opening/closing device 3 by an automatic carrying mechanism 7, while a next sample is set on a lid 8. Then the gas cylinder 5 is transferred to a calorific value measuring tank 1 by the mechanism 7 with the gas cylinder filled with high pressure oxygen and set inside the tank 1. Since an electrode is provided at the bottom of the tank 1 oppositely to an electrode rod 9 on a side of the lid 8 of the gas cylinder 5 at this time, simply setting the gas cylinder 5 at a predetermined position brings the electrode rod 9 and the electrode into contact to supply power thereby measuring a calorific value.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a calorific value measuring device of a type in which a sample is enclosed 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 above type is
As specified in JIS M 8814, the sample is enclosed in a bomb with an opening at the top, the screw-type lid is closed, high-pressure oxygen is injected into the bomb, and then the bomb is used for a calorific value measurement water tank. After setting the inside, an electric wire for ignition 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 apparatus, since the opening of the bomb is at the upper part, it is necessary to turn over the inside of the bomb to clean the inside of the bomb every time one measurement is performed. Since the electrode rod that penetrates the lid is also on the top of the bomb, it is necessary to pull out the electric wire through the multiple lids of the calorific value measuring water tank, which complicates the operation and also complicates the structure of the calorific value measuring water tank. It was a thing. Therefore, conventionally, all the operations for measuring the calorific value are manually performed, and it has been difficult to automatically perform the accurate calorific value measurement.

It can be moved.

The conventional bomb has a screw-type lid on the upper end, but the bomb 5 used in the present invention has a bell 8 having an opening facing downward and a lid 8 on the lower side as shown in FIG. It is a shape. The lid 8 is provided with a pair of electrode rods 9 for igniting the sample stored inside. Further, a grip portion 10 is formed on the upper end of the bomb 5 so that the robot hand 6 can easily chuck it. Further, as shown in FIGS. 3 and 4, the engaging portion between the bomb 5 and the lid 8 is of a bayonet type, and the protrusion 11 formed on the outer periphery of the lid 8
3 is fitted in the groove 12 on the inner circumference of the bomb 5 as shown in FIG. 3 and the lid 8 is rotated by a small angle, so that a reliable engagement is achieved as shown in FIG.

FIG. 5 shows the internal structure of the calorific value measuring water tank 1, wherein 13 is an outer tank, 14 is an intermediate tank, and 15 is an inner tank. An electrode 16 is provided on the inner bottom portion of the inner tank 15 so as to face the electrode rod 9 of the bomb 5, and when the bomb 5 is set inside the inner tank 15 as shown in FIG. 9
Is in contact with the upper end surface of the electrode 16 so that electricity can flow.

As shown in FIG. 5, a thermocouple thermometer 17 and a stirring propeller 18 are installed in the inner tank 15. The stirring propeller 18 may be externally rotated by a motor, but if the rotating magnetic field is used to rotate the propeller 18 by electromagnetic force, water leakage from the rotating portion can be completely prevented.

FIG. 6 shows the lid opening / closing device 3, and 19 is a guide for receiving the downward opening of the bomb 5 while aligning it, and a turntable 20 is provided below the center of the guide. .. The turntable 20 has a hole 21 into which a pair of electrode rods 9 protruding from the lid 8 of the bomb 5 can be fitted. When the turntable 20 is rotated by a lower rotation mechanism 22, the bomb 5 The lid 8 rotates with respect to the lid 8 to release or engage the above bayonet type engagement.
Can be opened and closed. 23
Is a pin for preventing the rotation of the bomb 5.

Reference numeral 24 shown in FIG. 6 is an automatic opening / closing type plug for supplying high-pressure oxygen to the inside of the bomb 5, and at the same time when the lid 8 of the bomb 5 is seated on the rotary table 20, the lid 8 is closed. High pressure oxygen can be supplied to the inside of the bomb 5 and combustion gas inside the bomb 5 can be discharged through a solenoid valve (not shown) provided in communication with the socket 25 and provided in the pipe line 26. Reference numeral 27 is an elevating mechanism for unlocking the plug 24 and the socket 25. With the above structure,
The lid opening / closing device 3 is capable of opening / closing the lid 8 of the bomb 5 and automatically supplying high-pressure oxygen.

FIG. 7 shows the internal structure of the cleaning tank 4. As shown, the bomb 5 with the lid 8 removed is inserted into the guide 26 at the center of the cleaning tank 4. A cleaning nozzle 28 that can be raised and lowered by a cylinder 27 is provided below it.

[0013]

The operation of the calorific value measuring device of the present invention thus constructed is as follows. First, the bomb 5 that has been measured is taken out from the inside of the calorific value measuring water tank 1 by the automatic transfer mechanism 7 and transferred to the lid opening / closing device 3. When the bomb 5 is set on the rotary table 20 of the lid opening / closing device 3, the automatic opening / closing plug 24 and the socket 25 on the lid 8 side communicate with each other.
The solenoid valve is opened to discharge the high pressure combustion gas filling the bomb 5. Next, when the rotary table 20 is rotated, the engagement between the bayonet type lid 8 and the bomb 5 is released. Therefore, the bomb 5 is chucked by the automatic transfer mechanism 7 and cleaned in the cleaning tank 4. In the present invention, since the opening of the bomb 5 is directed downward, it is possible to insert the cleaning nozzle 20 into the cleaning tank 4 as it is as shown in FIG. Also, the wash water will be naturally discharged. During this period, the lid 8 remains on the rotary table 20 of the lid opening / closing device 3.

After the cleaning of the inside is completed, the bomb 5 is transferred to the lid opening / closing device 3 again by the automatic transfer mechanism 7. In the meantime, the next sample is set on the lid 8, the bomb 5 is put on the lid 8 and the rotary table 20 is rotated in the reverse direction to close the lid 8. Then, after being filled with high-pressure oxygen, the bomb 5 is transferred to the calorific value measuring water tank 1 by the automatic transfer mechanism 7 and set therein. At this time, as shown in FIG. 5, the electrode rod 9 on the lid 8 side of the bomb 5 is attached to the bottom of the calorific value measuring water tank 1.
Since the electrode 16 is provided so as to be opposed to, the amount of heat generation can be measured by simply setting the bomb 5 at a predetermined position to bring the electrode rod 9 and the electrode 16 into contact with each other to conduct electricity. Therefore, in the calorific value measuring apparatus of the present invention, the bomb 5
It is not necessary to draw out an electric wire for energization to the upper part of, and the structure of the lid of the heat generation amount measurement water tank 1 can be simplified.

[0015]

As described above in detail, according to the present invention, the opening of the bomb is directed downward, and the bomb is automatically transferred by the calorific value measuring water tank, the lid opening / closing device, and the cleaning device. Since it can be sequentially moved to and from the tank, the calorific value can be measured fully automatically with excellent accuracy. Therefore, the present invention has an extremely great contribution to the development of industry as a calorific value measuring device that solves the conventional problems.
