Description

Hydrogen-oxygen source welding-cutting machine

The utility model belongs to welding, cutting, particularly the hydrogen-oxygen source welding-cutting machine of gas flame welding.

Traditional gas flame welding is to do the weldering source with acetylene, oxygen, transport difficult, seriously polluted, cost is high, the welding temperature is not high enough; Some hydrogen-oxygen source welding-cutting machines of Chu Xianing in recent years, water electrolysis is produced hydrogen-oxygen do the weldering source, though overcome some defectives that acetylene, oxygen are done the weldering source, but still there is easy leakage, cause unsafe factors such as electrolytic cell housing conduction, thereby can not be widely used in smelting, machine and industry, practicality extreme difference such as add.

The purpose of this utility model provides the without leakage hydrogen-oxygen of a kind of economy and durability source welding-cutting machine.

The purpose of this utility model is realized by following technical proposals.The hydrogen-oxygen source welding-cutting machine that this scheme provides comprises hydrogen-oxygen source machine and outer relay part, and hydrogen-oxygen source machine is made up of rectifier power source, electrolytic cell, electromagnetic pump, pressure controller, radiator, receiver, auxiliary tank etc., assembles in cabinet with pipeline; Outer relay part is backfire controller and welding torch.The electrolytic cell that it is characterized in that hydrogen-oxygen source machine is an integrated sealing structure, and the groove inwall is one deck insulation, corrosion resistant, exotic material; Electrolytic strip is two groups of conducting strips, a winding positive source, a winding negative pole.Two groups of alternate forks of electricity sheet are put and mutually insulated, and conducting strip center string is worn an insulating bar, and excellent two ends are fastened on the electrolytic cell end flanges with the insulation nut; The cabinet outer upper is equipped with moisture trap, and its import and gas outlet, receiver upper end join, and its outlet connects welding torch through backfire controller, and it is cover one escape pipe in water accumulation pipe, and cover one air inlet pipe constitutes in the escape pipe.

1. rectifier power source 2. electrolytic cells 3. electromagnetic pumps 4. pressure controllers 5. radiators 6. receivers 7. auxiliary tanks 8. moisture traps 9. backfire controllers 10. welding torches 11. electrolytic strips 12. insulating bars 13. felt pads 14. electrolytic cell inwalls 15. moisture trap air inlet pipe 16. moisture trap escape pipes 17. water accumulation pipes

Below in conjunction with accompanying drawing the utility model is further specified, as embodiment, electrolytic cell 2 is a seamless steel pipe, its inwall 14 is coated with one deck polyphenylene sulfide, electrolytic strip 11 is the stainless steel disk of center drilling, be separated by with teflon gasket between adjacent sheet, insulating bar 12 is four poly-rods, and the connecting line of related device is a nylon tube.Electrolytic cell is located at the cabinet bottom, and its inlet connects electromagnetic pump 3, and outlet connects pressure controller 4 and radiator 5 respectively; Receiver 6, auxiliary tank 7 are located at the cabinet middle part, and the receiver import is communicated with the electromagnetic pump of its below, the radiator and the auxiliary tank at rear respectively, and outlet connects moisture trap.Work as power connection, the machine startup work of hydrogen-oxygen source, electromagnetic pump just is pressed into electrolyte in the electrolytic cell, output hydrogen and oxygen gas mixture under the function of current, after the radiator cooling, inject receiver, enter moisture trap, utilize gas, water self proportion difference to separate from air inlet pipe 15, water is deposited on water accumulation pipe 17, and purified gas then is delivered to welding torch 10 from escape pipe 16 through backfire controller 9.

The utility model has the advantages that the electrolytic cell corrosion resistant, durable, high temperature resistant, the insulation, No leakage, safe and reliable; Volume is little in light weight, and is easy to operate, keeps in repair easyly, and only needing will Electrolytic strip is extracted out from electrolytic cell is whole, can change bad conducting strip, need not whole group of newspaper Useless. And the existing hydrogen-oxygen cutting-welding machine of unit power consumption gas production is big in using, the welding torch fire The flame temperature can reach 3300 ℃. Can be widely used in smelting, machine adds etc. needs weldering in a large number Cut the industry of processing.
