Temperature controller of water electrolytic welding / cutting machine {Temperature Controller of Water Eletrolytic Welding / Cutting machine}

[0001]

This invention proposes to solve the problem that the conventional hydrogen / oxygen mixed fuel generator 10 is not regulated due to the control of combustion temperature, and thus the hydrogen / oxygen mixed fuel which controls the combustion temperature of the hydrogen / oxygen mixed fuel generator 10 is limited. To provide a combustion temperature controller.

[0002]

The present invention relates to a combustion temperature controller for a hydrogen / oxygen fuel that can control the combustion temperature.

[0003]

As shown in Fig. 1, the conventional hydrogen / oxygen mixed fuel generator 10 is mainly used for welding or cutting metal materials, and is used as a substitute for a fuel generator using oxygen gas or aspirin gas. The hydrogen / oxygen mixed fuel generator 10 uses an electrolysis method, and mixes hydrogen and oxygen generated by electrolysis of the electrolysis solution (aqueous solution) in the electrolysis vessel 11, and then discharges it to the clearance 12. Then, the customs clearance 12 is brought into the combustion portion, and fire is emitted from the combustion portion, whereby welding and cutting of the metal material is performed.

[0004]

However, when the mixed gas of hydrogen and oxygen is combusted, the flame temperature is about a fixed temperature of about 2,800 to 3,000 ° C. As a result, the hydrogen / oxygen fuel generator 10 is valuable only for special metal materials that are welded and cut at high temperatures. Therefore, there is a problem that the use is limited.

[0005]

In order to achieve the above object, the hydrogen / oxygen mixed fuel of the hydrogen / oxygen mixed fuel described in claim 1 has a combustion temperature controller, a temperature control passage, three intervening pipes, a first gas inlet pipe, and a second gas inlet pipe. As the combustion thermostat, the thermostat is a closed hollow cylinder with one cover on the top, one gas outlet on the top, and one inlet tube of the three channels for transporting the mixed hydrogen / oxygen fuel. It is connected to the clearance of the hydrogen / oxygen fuel generator, the first gas distribution pipe is connected to the bottom of the temperature control cylinder, one end is installed in the temperature control cylinder, and the other end is the entrance of one of the three intervention pipes. The other end is connected to one of the three inlet pipes and the combustion temperature is changed by changing the flow rate ratio between the hydrogen / oxygen fuel and the low combustion temperature fuel by a control valve that can deduct the gas inflow. It was assumed to be adjustable.

[0006]

The invention of Claim 2 makes it possible to detect the amount of low combustion temperature fuel by installing an indicator on the side of the temperature control barrel in the combustion temperature controller of the hydrogen / oxygen mixed fuel described in Claim 1. Therefore, it is easy to supplement the low combustion temperature fuel.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of the combustion temperature regulator of hydrogen / oxygen mixed fuel which concerns on this invention (it is simply called a "combustion temperature regulator") is demonstrated about drawing.

[0008]

As shown in Fig. 2 and Fig. 3, the combustion temperature controller mainly consists of a temperature control barrel 20, three intervening port pipes 30, a first gas inlet pipe 40 and a second gas inlet pipe 50.

The thermostat 20 is a sealed hollow cylinder, one of which has a cover 21 on the top, one gas outlet pipe 22 on the top, and one liquid level display meta 23 on the side.

[0009]

Three intervening pipes 30 are connected to the customs clearance 12 of the hydrogen / oxygen mixed fuel generator 10, and the first gas inlet pipe 40 has one end in contact with the bottom of the thermostat 20, and the other end has three It is connected to one inlet of intervention tube 30.

[0010]

One end of the second gas inlet pipe 50 is connected to the upper part of the temperature control tube 20 and the bottom of the gas inlet pipe 22, and the other end is connected to one inlet of the strength inlet pipe 30. The control valve 51 is a valve capable of subtracting the gas inflow amount of the second gas inflow pipe 50.

[0011]

Opening the cover 21 of the thermostat 20 and inserting a suitable amount of low combustion temperature fuel (e.g. gasoline, alcohol, alcohol liquid, etc.) into the combustion temperature control is possible, ie hydrogen / oxygen mixed fuel generator 10 or the second gas inlet pipe 50 is passed through the thermostat 20 to control the combustion temperature.

[0012]

As shown in Fig. 4, the control valve 51 in the second gas inlet pipe 50 is completely opened and the hydrogen / oxygen mixed gas from the tube is inserted into the temperature control tube 20 through the second gas inlet pipe. Since the first gas inlet pipe 40 has a liquid pressure of the mixed liquid, the hydrogen / oxygen mixed gas is naturally supplied from the second gas inlet pipe 50 to the ignition portion (or other fuel having a function), and thus the combustion temperature of the hydrogen / oxygen mixed gas is It reaches about 3000 ° C.

[0013]

As shown in Fig. 5, when the control valve 51 of the second gas inlet pipe 50 is completely received, all of the hydrogen / oxygen mixed gas from the clearance 12 enters the temperature control cylinder 20 from the first gas inlet pipe 40. Inside the thermostat 20 is a mixed liquid. The hydrogen / oxygen mixed gas entering the first gas inlet tube 40 is also mixed with the mixed liquid to make the combustion temperature changeable. After the hydrogen / oxygen mixed gas and the low combustion temperature fuel are mixed, they are provided from the gas outlet pipe 22 to the combustion section (or other fuel having a function).

As a result, the combustion temperature is lowered to 900 ° C.

[0014]

As shown in FIG. 6, when only half of the control valve 51 of the second gas inlet pipe 50 is closed, a portion of the hydrogen / acid mixture gas of the clearance 12 enters the temperature control cylinder 20 from the first gas inlet pipe 40. As a result, the ratio of hydrogen / oxygen mixed gas and low combustion temperature fuel is changed. The hydrogen / oxygen mixed gas mixed with the low combustion temperature fuel is provided in the ignition portion (or other functioning fuel) of the gas outlet pipe 22 and its combustion temperature is 900 to 3000 ° C. The combustion temperature is determined by the closing degree of the control valve 51.

[0015]

In addition, since the first gas inflow pipe 40, the second gas inflow pipe 50, and the clearance 12 have a suitable air pressure, the mixed liquid does not flow backward. The gas outlet pipe 22 may be provided with a flame backflow prevention device or other safety device if necessary. In addition, the control valve 51 and the liquid level display meta 23 as the display metameter can be installed at an appropriate position outside or other than the hydrogen / oxygen fuel generator 10 by extending the pipe to increase the bivariability.

[0016]

Combustion flame temperature can be controlled, and welding by reducing flame, oxidation prevention of cutting part and cleaning surface can be cleaned.

According to this invention, the combustion temperature controller of hydrogen / oxygen mixed fuel can be controlled inside the hydrogen / oxygen mixed fuel generator to control the combustion temperature of the flame, and the welding or cutting of various metal materials through the use of the combustor and the reducing flame. It is used for processing. In addition, it can be used for heating the article or for other purposes.
