DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0025] This embodiment provides an electrical dual-purpose welding device, such as Figures 1 to 5 As shown, it mainly includes an oxyhydrogen generator, a drying and cooling tank 19 and a condensation and washing tank 30 arranged inside.

[0026] The oxyhydrogen generator generates oxyhydrogen gas for welding through electrolysis reaction. The oxyhydrogen generator includes a metal shell 12 containing an electrolyte 6 and an electrolysis device 1 arranged in the metal shell 12. The electrolysis device 1 is composed of an insulating plate with grooves and small holes on the upper and lower sides. Multiple groups of electrode sheets 3 are installed in the grooves and two high-nickel electrode end plates 2 are installed to penetrate the shell of the electrolysis device. The connection between the electrode end plates 2 and the shell of the electrolysis device is installed with a locking nut 5, and a sealing ring 4 is provided at the connection. The electrode end plates 2 are used to connect the welding device power supply (see patent document CN113897632A for details). The upper part of the metal shell 12 is connected to a water-gas separation cooling tank 13, and the oxyhydrogen gas generated by electrolysis enters the water-gas separation cooling tank 13 through a gas channel C opened on one side of the upper part of the metal shell 12. A water-gas separation baffle 9 is also provided before the gas channel C in the metal shell 12, and a fin heat sink 8 is provided directly below the water-gas separation baffle 9. The liquid (electrolyte) after water-gas separation flows into the fin heat sink 8 from the bottom gap of the water-gas separation baffle 9 to dissipate heat. After the heat dissipation is completed, the electrolyte continues to flow into the electrolysis device 1 from the bottom of the fin heat sink 8 for electrolysis, thereby realizing a non-power circulation electrolyte cooling. The gas channel C is located after the water-gas separation baffle 9, which can effectively remove most of the gas and liquid that are not separated cleanly. The liquid level of the electrolysis device 1 is measured by a water level probe 10, which passes through the water-gas separation baffle 9 and is inserted into the fin heat sink 8. The liquid level here is relatively static and has small fluctuations, so a more accurate liquid level can be measured. Among them, the water-gas separation cooling tank 13 is equipped with a tubular heat sink 14, and a hydrogen-oxygen generator outlet 15 for outputting gas is provided.

[0027] In order to improve the heat dissipation performance of the hydrogen-oxygen generator, in some embodiments, the outer wall of the metal shell 12 is also provided with a heat dissipation fan 7 and a plurality of heat dissipation patches 16, and an aluminum hydrogen-oxygen generator heat dissipation base is provided on the bottom outer wall of the metal shell 12. The heat dissipation base increases the contact area with the air by providing grooves, adding guide columns, etc., thereby accelerating the heat dissipation process.

[0028] The drying and cooling tank 19 is used to dry and cool the hydrogen and oxygen produced by the hydrogen and oxygen generator. Figure 4 As shown, the air inlet 17 of the dry cooling tank 19 is connected to the air outlet 15 of the hydrogen-oxygen generator, and the non-dried gas and liquid are sent to the bottom of the dry cooling tank 19, and are fully contacted with the desiccant 18 in the dry cooling tank 19 before being discharged from the air outlet 23. The outer wall of the dry cooling tank 19 is provided with a tubular radiator 20, which is used to cool the desiccant and gas and liquid in the tank. The bottom of the dry cooling tank 19 is provided with an electromagnetic drain valve 21, which is used to regularly discharge the moisture after the desiccant is adsorbed and saturated, and discharge it to the bottom tray through the drain port 22.

[0029] The condensation and washing tank 30 is used to cool and filter the output gas of the drying and cooling tank 19. Figure 5As shown, the condensation washing tank 30 contains filtered water 31. The temperature of the filtered water 31 can be reduced to below room temperature through the cooling fins 25 at the bottom of the condensation washing tank 30, so that the condensation washing tank inlet 24 connected to the dry cooling tank outlet 23 is sent to the filtered water below room temperature through the internal pipeline for cooling and filtration, so that the gas water content is lower and cleaner. The cooling fins 25 dissipate heat through the condensation washing tank heat dissipation base 28, and the heat dissipation base increases the contact area with the air by setting grooves and adding guide pillars, thereby accelerating the heat dissipation process.

[0030] Finally, the clean hydrogen and oxygen gas with low water content is guided to the hydrogen and oxygen outlet 35 of the welding device through the condensation washing tank outlet 29 for combustion. The condensation washing tank 30 also has a certain fire-retardant effect. When tempering occurs, there is water in the middle to prevent the drying and cooling tank 19 from burning.

[0031] In some embodiments, the condensate washing tank 30 is further provided with an overflow solenoid valve 26 and an overflow port 27 . When the condensate 31 reaches a certain water level, the overflow solenoid valve 26 is opened at a fixed time to drain water from the overflow port 27 .

[0032] The electrical dual-purpose welding device provided in this embodiment has a heat dissipation shutter 34 and a heat dissipation port 37 on its housing, and is provided with a water inlet 36 corresponding to the hydrogen and oxygen generator and the condensation washing tank 30. The welding device housing is also provided with an electric welding output electrode 33 and a hydrogen and oxygen outlet 35, as well as a switch 32 for switching between electric welding and gas welding. The welding device also includes a plurality of feet 38 for easy movement and fixing.

[0033] Traditional welding equipment cannot take into account the welding of gold, silver, copper, iron, stainless steel, aluminum and all alloy metals, because the melting points of different metals are different and the required welding temperatures are different. The welding device provided in this embodiment fills this gap. This welding machine can use traditional metal welding rods to weld some steel materials such as iron and stainless steel, and can also be converted into flame (hydrogen and oxygen gas) welding. Its flame welding temperature can be adjusted by adjusting the gas volume and controlling the flame distance. For some precious metal processing, it can achieve temperature concentration, flame non-dispersion, copper and aluminum welding without deformation and other advantages, which are not available in traditional welding machines. In addition, because the flame temperature is high and concentrated, this equipment can also be used when welding quartz glass in the non-metallic field.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Under the idea of ​​the present invention, the technical features in the above embodiments or different embodiments can also be combined, and there are many other changes in different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
