DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic cleaning method for a calorimeter bomb used in an automatic measuring device for the calorific value of various substances.

[0002]

2. Description of the Related Art In order to measure the calorific value, a method is employed in which an object to be measured is sealed in a bomb, filled with high-pressure oxygen, placed in a water tank, and then burned through an ignition wire inside the bomb through an electric current. I have. Since dirt such as ash adheres to the inner surface of the bomb after the calorific value measurement is completed, the inner surface of the bomb is manually cleaned every measurement in the conventional manual calorific value measuring method.

[0003] An automatic calorific value measuring device has also been developed in which a part of the calorific value measuring process is automated. In this case, only the bomb body having a simple structure is moved to the cleaning position and the nozzle is cleaned with a nozzle. Therefore, there is no method for automatically cleaning a bomb lid having a complicated structure including a heating wire to which water cannot be applied. For this reason, if used repeatedly, there is a risk that dust such as ash may adhere, leakage of the electrode portion, damage to the O-ring, increase in measurement error, and the like may occur.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems and provides a method for automatically cleaning a calorimeter bomb that can clean both the bomb body and the bomb lid without requiring extra space. It has been completed to provide.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems. The present invention is to open a bomb whose heating value has been measured up and down, and to protect the heating wire of the bomb cover from water drops falling from above. Is located between the bomb body and the bomb lid, and the bomb lid is cleaned with the nozzle from a position lower than the heating wire, and the bomb body is also cleaned. It is assumed that.

[0006]

According to the present invention, the bomb body and the bomb lid are opened up and down, and the respective parts are simultaneously cleaned by the nozzle. At this time, the inner cover of the horizontal cover prevents the washing water of the upper bomb main body from hitting the heating wire of the lower bomb lid. The nozzle for cleaning the bomb lid performs cleaning from a position lower than the heating wire. For this reason, the bomb main body and the bomb lid can be washed at the same position at the same time without wetting the heating wire or cutting the heating wire, and has the advantage that no extra space is required.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to the illustrated embodiments. FIG. 1 shows the entire automatic calorific value measuring apparatus, in which 1 is a calorie measuring unit, 2 is a high-pressure oxygen inlet / outlet unit, and 3 is a bomb opening / closing and washing unit. The calorie measuring unit 1 includes a water tank 4 and a water tank lid 5 having an opening / closing mechanism, and the high-pressure oxygen inlet / outlet unit 2 includes a high-pressure oxygen injection and discharge nozzle 6. Reference numeral 7 denotes a bomb, and a vertical transfer cylinder 9 provided with a bomb chuck 8 at a lower end thereof.
Is moved between these three positions by a left and right transfer cylinder 10 which moves the hopper in the horizontal direction.

The bomb 7 for which the calorific value measurement has been completed is taken out of the water tank 4 of the calorific value measuring section 1 by the bomb chuck 8, and the internal combustion gas is discharged from the high-pressure oxygen inlet / outlet section 2. Next, the bomb 7 is moved to the bomb opening / closing and cleaning section 3, and the bomb cover 7b is rotated with respect to the bomb body 7a to separate them from each other. As shown in FIG.
Move 7a upward.

Next, the tubular horizontal cover 11 is swung from the lateral direction to be positioned between the bomb main body 7a and the bomb lid 7b. As shown in FIG. 2, the horizontal cover 11 has a cylinder body cleaning nozzle 13 and a bomb lid cleaning nozzle 14 attached to a cylindrical main body 12 for preventing the washing water from scattering around. is there. Further, inside the main body 12, an umbrella-shaped cover 16 for protecting the heating wire 15 of the bomb lid 7b from water drops falling from above is provided. This umbrella-shaped cover 16
Is for guiding water that has fallen from above to the surroundings and discharging the water below the horizontal cover 11.

After the lateral cover 11 is positioned between the bomb main body 7a and the bomb lid 7b in this manner, cleaning water is ejected from the bomb main body cleaning nozzle 13 and the bomb lid cleaning nozzle 14 to discharge the bomb main body 7a. And the bomb lid 7b are simultaneously washed. As described above, the water falling from the bomb main body cleaning nozzle 13 is blocked by the umbrella-shaped cover 16 so that the bomb cover
The heating wire 15 of FIG. 7b is not wet, and the bomb lid cleaning nozzle 14 is cleaned from a position lower than the heating wire 15 as shown in FIG. Also, the heating wire 15 can be cut by the power of the nozzle cleaning water,
There is no deformation. As shown in FIG. 4, in the embodiment, three sets of bomb lid cleaning nozzles 14 are provided at intervals of 120 °, and the washing water from each nozzle completely covers the upper surface of the bomb lid 7b. Note that it is also possible to adopt a method of rotating the bomb lid 7b with only one bomb lid cleaning nozzle 14.

When the cleaning is completed in this way, drying air is blown out from the bomb body cleaning nozzle 13 and the bomb lid cleaning nozzle 14 to remove moisture. Then, swing the horizontal cover 11 to the original standby position, and then
A voltage is applied between the electrodes 17 and 7 of 7b to cause the heating wire 15 to generate heat,
Allow this part to dry completely. This is done in order to completely remove the moisture from the heating wire 15 even if the washing water is not directly applied to the heating wire 15 due to splash or the like.

[0012]

As described above, according to the method for automatically cleaning a calorimeter bomb of the present invention, both the bomb body and the bomb lid can be automatically cleaned, resulting in the adhesion of dirt such as ash. Trouble can be eliminated. Further, since the bomb main body and the bomb lid can be washed at the same position without wetting the heating wire, there is an advantage that no extra space is required.
