Description

A kind of instantaneous pre-heating oil cutting welder

The utility model relates to fuel oil and cuts the weldering field.

At present, when metal being cut or the thin-sheet metal welded, main what use is oxygen, acetylene cutting-welding machine, it is made up of the steel cylinder and the oxygen cylinder of acetylene generator or splendid attire acetylene, the on-the-spot one side of using of acetylene generator is dangerous, and easy contaminated environment, and the acetylene gas cost is higher simultaneously; The fusing soldering welder that also has that relates to cutting welder, fusing soldering welder is made up of the supercharging atomising device of gasoline cistern that escape pipe is housed and gasoline cistern, though the fusing soldering welder use cost is lower, but because its combustion-supporting employing air, so the combustion heating amount is low, only be used for the repair welding or the fusing of small article, as making jewel in repairing car water tank and the handicraft workshop, and can not do the weldering of cutting of big part goods.

The purpose of this utility model is to provide a kind of a kind of novel cutting welder that collects oxygen, acetylene cutting-welding machine and fusing soldering welder two machine advantages, makes gas generator aerogenesis cost low, and safety is free from environmental pollution, cuts the requirement that weldering reaches oxygen, acetylene cutting-welding machine.

The technical scheme that realizes the utility model purpose is: the gas generator top is shaped on the air storage chamber of band safety valve, and the venthole of air storage chamber is connected with cutting and welding torch by defeated Gas Pipe; The gas generator inner bottom part is equipped with the atomizing jet thrust, and this atomizing jet thrust is connected with air compressor by the air compressor wireway, on this wireway air heater is housed; Oil temperature sensor is equipped with in gas generator inside, and oil temperature sensor is connected with lead with temperature controller, air heater, and the air heater on temperature relay on the gas generator outer wall and the air compressor wireway is cascaded; Oxygen cylinder is connected on the oxygen interface of cutting and welding torch by oxygen hose.

Describe the utility model CONSTRUCTED SPECIFICATION and operating position in detail below in conjunction with embodiment and accompanying drawing thereof:

Fig. 1 is the structural representation according to a kind of instantaneous pre-heating oil cutting-welding machine of the novel proposition of this reality.

As shown in Figure 1: be shaped on oil filler 12 on the top of gas generator 1, the top is shaped on the air storage chamber 2 of band safety valve 21, separate with oil droplet filter with holes 11 between gas generator 1 and the air storage chamber 2, in air storage chamber 2, be shaped on screen pack 22, adorn magnetic valve 23 successively on the venthole conduit of air storage chamber 2, Pressure gauge 24, go out air cock 25, check valve 26, the defeated Gas Pipe 31 of the venthole conduit of connection cutting and welding torch 3 and gas storage sky 2 is equipped with constant temperature electric heating silk 32 at nearly cutting and welding torch 3 places in the Gas Pipe 31; Check valve 44, chamber hot-air heater 42 are housed on the wireway 41 of air compressor 4, and this wireway 41 is connected on the atomizing jet thrust 43 of gas generator 1 inner bottom part; Oil temperature sensor 51 is housed in the gas generator 1, and oil temperature sensor 51 connects temperature controller 5 and air heater 42 by lead, and the temperature relay 6 that is contained on gas generator 1 outer wall is cascaded with heater 42; Temperature controller 5, air compressor 4, magnetic valve 23, constant temperature electric heating silk 32 are connected with power supply by lead; Air pressure is set up by air compressor 4, contains oxygen cylinder and is connected with oxygen interface 33 on the cutting and welding torch through oxygen hose.

When the utility model cuts the weldering application in the production scene, at first open oil filler 12, but in gas generator 1, add fuel oil, seal then, close out air cock 25, set up air compressor 4 and go out atmospheric pressure and temperature controller 5, the control temperature of temperature relay 6, after oxygen hose is communicated with Sheng oxygen cylinder and cutting and welding torch oxygen interface 33, the power turn-on switch, magnetic valve 23 is opened, the compressed air of air compressor 4 is behind the check valve on the wireway 41 44, heat the atomizing jet thrust of sending in the gas generator 1 43 through air heater 42 again, the preheating pressure air of atomizing jet thrust 43 ejections makes shower nozzle oil atomization nearby rise up into the top of combustion generator 1 in oil, enter in the gas storage sky 2 through oil droplet filter 11, fogging oil in the air storage chamber 2 or gas enter air storage chamber 2 tops through filter screen 22, after treating that combustible gas reaches certain pressure, open out air cock 25, combustible gas is in check valve 26 enters the defeated Gas Pipe 31 that connects cutting and welding torch, open oxygen switch and oil and gas switch on the cutting and welding torch, light back setting oil gas and oxygen proportion and just can cut or weld.In cutting the weldering process, when if the oil temperature surpasses setting in the gas generator 1, oil temperature sensor 51 will be to temperature controller 5 signals, make air heater 42 outages, once oil temperature sensor 51 or temperature controller 5 are malfunctioning, temperature relay 6 on gas generator 1 outer wall can make air heater 42 outages equally because of too high disconnection of oil temperature; When gas generator 1 internal pressure surpasses setting, safety valve 21 automatically excessive gas decompressions; If in low temperature environment, use, also can connect the constant temperature electric heating silk 32 in the defeated Gas Pipe 31 when cutting weldering, make not condensation of oil gas, guarantee to cut normally carrying out of weldering.Behind the end-of-job, cut off the electricity supply, magnetic valve 23 cuts off oil gas vent, shuts oil gas, oxygen switch on the cutting and welding torch 3 at last.

The utility model has the advantages that: (1) is owing to adopt hot compression in the gas generator Air is directly to the fluid local heat, but moment atomizing fluid produces a large amount of oil gas, and is real Showed start and just can cut weldering, gas generator does not produce pollution to environment simultaneously; (2) Secondary temperature control safeguard measure has been adopted in fluid temperature rise in the gas generator, made behaviour Do safer.
