The first embodiment,

As shown in fig. 1, the present application provides an electrolytic water welding apparatus including a transformer 100, an electrolytic cell 200, a pressurized tank 300, and a spray gun 400.

The transformer 100 converts the alternating current into the direct current, and then the direct current is transmitted to the positive pole post 250 and the negative pole post 260 of the electrolytic cell 200, part of the electrode plates 210 are connected with the positive pole post 250, and the rest of the electrode plates 210 are connected with the negative pole post, so that one part of the electrode plates 210 are positively charged, the other part of the electrode plates 210 are negatively charged, and the electrolytic cell 200 is filled with alkaline electrolyte. The electrolyte is subjected to electrolytic reaction at the part in contact with the electrode plate 210 to generate hydrogen, oxygen and mixed gas, the generated mixed gas enters the one-way valve below the pressurizing tank 300 from the electrolytic cell, the pressurizing tank 300 is filled with liquid, and the one-way valve can ensure that the liquid in the pressurizing tank 300 cannot flow backwards into the electrolytic cell; the gas outlet 270 is arranged above the pressurized tank 300, the gas outlet 270 above the pressurized tank 300 is connected with the spray gun 400, and when a certain amount of mixed gas is gathered in the pressurized tank 300, enough gas pressure exists at the moment to send the mixed gas in the pressurized tank 300 out of the spray gun 400, so that the welding operation is completed.

The spray gun 400 is an anti-backfire spray gun, so that the safety of equipment can be improved; the alkaline electrolyte is a saturated sodium hydroxide solution, so that the cost can be reduced.

The electrolytic cell 200 is a place where an electrolytic reaction occurs, and during the process of electrolysis, the resistance of the liquid itself may cause heat generation, the temperature in the electrolytic cell 200 may increase, and when the temperature of the electrolyte inside the electrolytic cell 200 increases to 100 °, the electrolyte may boil, which affects the efficiency of water electrolysis, and may cause the electrolytic water welding apparatus not to be used for a long time. If one wants to increase the length of time that the welding apparatus is used in the electrolysis of water, one needs to ensure that the electrolyte does not boil. Therefore, the shell 230 of the electrolytic cell 200 is made of heat-conducting metal, the shell 230 is further provided with heat dissipation fins 231, the surfaces of the heat dissipation fins 231 are further coated with graphene, and the heat dissipation fins 231 can enlarge the contact area between the shell 230 and air and increase the speed of passive heat dissipation; the graphene can increase the heat exchange rate between the shell and the air, and further increase the heat dissipation speed. Because the higher the temperature of the electrolyte, the lower the resistance value, and the lower the calorific value, when the electrolyte is at a certain temperature, the heating speed can be equal to the heat dissipation speed, so that the temperature in the electrolytic cell 200 maintains a relatively stable level, and the service life of the whole electrolytic water welding device is prolonged.

The transformer 100 converts ac power into dc power, and although ac power can also electrolyze water, if ac power is directly introduced into the electrolytic cell 200, the ac power not only has a slow reaction speed, but also accelerates passivation of the electrode plate 210.

The housing 230 of the cell 200 is made of a thermally conductive metal. In this embodiment, the housing 230 of the electrolytic cell 200 is preferably made of stainless steel, which prevents water leakage and rust. This configuration provides a low cost implementation while reducing the overall weight of the device and improving portability. The case 230 is in direct contact with the electrolyte in the electrolytic cell 200, and the heat of the electrolyte is transferred to the case through the case 230 made of a heat conductive metal. The heat dissipation fins 231 provided on the housing 230 can increase the contact area of the housing 230 with air, increase the heat dissipation speed, thereby avoiding the reaction stop of the internal liquid due to boiling, and increasing the continuous use time of the whole electrolytic water welding device.

The upper end of the electrolytic cell 200 is provided with a detachable gas valve 220, and when the gas valve 220 is detached, a user can replenish water into the electrolytic cell 200 from a hollow space below the gas valve 220. The gas valve 220 disposed above is an outlet for hydrogen and oxygen when the gas valve 220 is mounted. During the electrolysis process, the generated hydrogen and oxygen enter the lower part of the pressurized tank 300 through the conduit 240 through the gas valve 200, the part of the lower part of the pressurized tank 300 connected with the conduit 240 is provided with a backflow prevention interface 310, the backflow prevention interface 310 can ensure that the mixed gas enters the pressurized tank 300, and the liquid in the pressurized tank 300 cannot flow back to the conduit 240.

The pressurized tank 300 is filled internally with a quantity of liquid, the volume of which is generally equal to one third of the volume of the pressurized tank 300. After the mixed gas of hydrogen and oxygen enters the pressurized tank 300 from the backflow prevention connector 310 at the bottom of the pressurized tank 300, the mixed gas is accumulated above the inside of the pressurized tank 300 under the action of buoyancy, and after the mixed gas reaches a certain amount, the mixed gas can be sent out from the spray gun 400 by the air pressure inside the pressurized tank 300, so that the air pressure requirement of welding operation is met.

According to some preferred embodiments of the present application, the pressurized canister 300 is further provided with a bleeder valve and a barometer. Sometimes, the speed of using the mixed gas by the user is slow, and the mixed gas of hydrogen and oxygen may be excessively accumulated in the pressurization tank during the electrolysis. The user can use the barometer can monitor the inside atmospheric pressure of pressure boost jar, and when atmospheric pressure rose higher degree, through the manual unnecessary gas of discharging of snuffle valve, can avoid the inside atmospheric pressure of pressure boost jar too high, the device has reduced the potential safety hazard. The transformer 100 is also provided with a switch, and when a user observes that the value of the barometer on the booster jar 300 is close to the limit air pressure which can be borne by the booster jar 300, the user can temporarily close the transformer 100 to stop the reaction in the electrolytic cell, so that the waste of resources caused by the fact that air must be discharged through an air escape valve is avoided.

According to some preferred embodiments of the present application, referring to fig. 2, when the housing 230 is connected to the positive post 250 and the negative post 260, in order to prevent electrical contact therebetween, an insulating ring 232 is disposed on the housing 230, and the insulating ring 232 can prevent the positive post 250 and the negative post 260 from making electrical contact with the housing 230, thereby improving the overall safety.

According to some preferred embodiments of the present application, the heat dissipating fins 231 are hollow inside and filled with a heat conductive liquid. The heat-conducting liquid is a volatile liquid, preferably ammonia, methanol or acetone. The heat-conducting liquid at the position of the heat-dissipating fin 231, which is in direct contact with the heat source, becomes gaseous after being heated, flows in the cavity inside the heat-dissipating fin 231, and is condensed at a place with relatively low temperature, so that the heat can be more uniformly conducted to other parts of the heat-dissipating fin 231, the heat-dissipating effect is enhanced, and meanwhile, any electrolyte cannot be consumed.

According to some preferred embodiments of the present application, sometimes the electrolysis speed of the electrolyte is relatively fast, the heat generation amount of the electrolytic cell 200 is relatively large, and the problem of boiling of the electrolyte is difficult to completely solve by passive heat dissipation. A heat dissipation fan is further disposed on the heat dissipation fins, and the heat dissipation fan is powered by a transformer, so as to increase the heat dissipation speed of the housing 230 by increasing the air flow speed. This structure can improve the heat dissipation effect of the case 230 with low cost. Preferably, the contact part of the heat dissipation fin and the heat dissipation fan is made of red copper, and the structure has good heat conduction performance and can improve the heat dissipation effect with minimum cost.

The insulating rubber ring 213 can prevent the electrode plates from contacting with each other, and the insulating rubber ring 213 also plays a role of containing the electrolyte.

The structure utilizes the insulating rubber ring 213 to replace a part of the shell, reduces the volume of the shell 230, reduces the weight and the manufacturing cost of the electrolysis equipment, and improves the portability.

A communication hole 211 is provided below each electrode plate 210, and the communication hole 211 enables liquid inside the electrolytic cell partitioned by different electrode plates to freely flow. Similarly, a gas guide hole 212 is formed above each electrode plate 210, and the gas guide hole 212 can ensure that gas generated between different electrode plates can flow out from a gas valve 220 disposed at one side of the housing 230.
