Description

Structure of CO2 Welding Fume Suction Torch with in Flexible Suction Pipe and Fume Collector use of magnet}

The present invention relates to a welding fume dust collector which sucks fume generated during CO2 arc welding. More specifically, a lattice, such as iron oxide, contained in the fume generated during welding is introduced into the filter device. It is primarily adsorbed by the magnetism of the mounted magnets, and other harmful factors such as dust, gas, etc. can be purified through the filter device 10 to improve the health of the worker and improve the working environment. The present invention relates to a structure of a welding fume dust collector for improving efficiency.

Revolutionary developments in industries such as shipbuilding, automobiles, heavy equipment, construction, etc. were made rapidly as CO2 welding emerged, and the type of CO2 welding wire was also filled with solvents for the purpose of stabilization and deoxidation of the arc. Due to diversification, welding fumes and welding gases, which are harmful to humans and the environment, generated during CO2 welding work, are emerging as serious industrial safety problems. Such welding fumes and welding gases are deposited in the lungs when a person is inhaled and have a fatal adverse effect on the human body. To protect workers' health from these, wearing protective equipment such as dust and gas masks or installing dust collectors in the workplace Efforts have been made to solve this problem, for example, by using a welding fume dust collecting torch.

The dustproof. Personal protective equipment such as gas masks do not act as a primary protection, but they do not provide close protection from the generation of fumes and cause long periods of breathing without keeping the replacement cycle of the wheel. There was a risk of depositing around the worker's eyes and the respiratory tract, causing vision impairment or skin damage and pneumoconiosis.

In addition, the conventional dust collector is a dust and toxic gas specialized dust filter structure, when heavy metal fumes such as iron oxide, which occupy 45-50% of the welding fume composition, are first adsorbed to the filter, causing clogging of the filter. It was an uneconomical structure because it not only prevented smooth dust collection and purification, but also had to replace the wheels frequently due to the wheel adsorption of heavy metals.In addition, the installation cost was excessive, and it did not block harmful gases and welding fumes that directly enter the worker. In fact, it was difficult to apply in narrow workshops such as block workshops and panel factories in shipbuilding.

The present invention is made to solve the above problems, the object of the present invention is to solve the problems caused by the structure of the conventional fume suction CO2 torch and dust collector and to effectively suck and collect the harmful fumes generated during welding By discharging to prevent the inhalation of harmful fumes to the worker to protect the worker's health and improve the working environment, and to provide a welding fume dust collector that can improve the work efficiency.

The object of the present invention is the front end of the grip-mounted torch body that is easy to adjust the angle connected to the welding nozzle is equipped with a suction nozzle that slides back and forth at the end of the welding fume suction pipe made of rubber or similar soft material. The welding fume suction torch is provided with a vacuum chamber inside the upper end of the housing where the discharge port is formed by the connecting pipe, a suction motor is installed between the vacuum chamber and the discharge port, and a fume box is installed at the lower end where the suction pipe is formed on one side. It is achieved by the structure of the welding fume dust collector, characterized in that the magnet is installed horizontally inside the detachable side on the side and the non-ferrous tube is opened on the suction pipe side, and the upper part of the non-irradiation tube is connected to a dust collecting device equipped with a filter device. do.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 is a schematic view showing the structure of a welding fume dust collector according to the present invention, the structure of the present invention is a welding fume suction torch 18, a wire transfer device for controlling a working range while supplying welding gas ( 15) and a dust collector 16 provided with a filter device.

The structure of the welding fume suction torch 18 is connected to the welding nozzle 1 as illustrated in FIG. 2 and the front end of the grip 5 having the torch body 4 having an easy angle adjustment therein. The end of the welded fume suction pipe 3 made of rubber or similar soft material is provided with a suction nozzle 2 sliding back and forth.

The structure of the dust collecting device 16 is provided with a vacuum chamber 11 inside the upper end of the housing in which the discharge port 13 is formed as shown in FIG. 3 for suction between the vacuum chamber 11 and the discharge port 13. A motor 12 is installed, and a fume box 6 is installed at a lower end of the suction pipe 7 formed on one side thereof, and the magnet 9 is horizontally installed inside the other side of the suction pipe 7 in a detachable manner. A non-ferrous tube 8 having an open suction side 7 is installed, and a filter device 10 is installed at an upper end of the non-ferrous tube 8. On the other hand, it is a conventional wire feeding device 15 wound around the connecting pipe so as to adjust the working range while supplying the welding gas.

Referring to the operation and effect of the present invention configured as described above, when the operator performs the welding, the welding fume is generated, the welding fume is released into the atmosphere and at the same time the suction motor 12 provided in the dust collector 16 at the same time As a result, the welding fume is sucked into the welding suction pipe nozzle 2 surrounding the outside of the welding nozzle 1. The suction pipe nozzle 2 is movable at the same time by adjusting the suction distance by allowing the slide movement to be performed. The welding fume can be more effectively sucked. The welding fume sucked by the welding suction pipe nozzle 2 is introduced into the housing through the welding fume suction pipe 7. The welding fume introduced into the housing through the suction pipe 7 is shown in FIG. Iron oxide (heavy metal) is easily adsorbed by the magnetic force on the outer surface of the non-ferrous tube 8 in which the magnet 9 having magnetic force is built in, and the welding fume is primarily filtered. It is moved upward by the suction force of 12) and the welding fume is filtered secondly by the filter apparatus 10 when moving upward. The secondary filtered welding fume is discharged into the atmosphere through the outlet 13 through the vacuum chamber and the suction motor. Therefore, heavy metal fume such as iron oxide, which accounts for 45 to 50% of the composition of the welding fume, which is a problem of the conventional dust collector. As it is directly adsorbed by the filter, it causes clogging of the filter, which prevents the smooth collection and purification of dust and harmful gas, and also requires frequent replacement of the filter due to the filter adsorption of heavy metals. By effectively collecting and purifying other harmful factors such as dust and gas, it is possible to improve worker's health protection and work environment and improve working efficiency. When not using the dust collector 16, When the iron oxide adsorbed on or after the operation is to be removed, as shown in FIG. When the magnet 9 inserted into the non-ferrous tube 8 is pulled out, the magnetic force is lost, and the iron oxide is easily released from the non-ferrous tube 8 so that the dust is dropped and collected in the fume box 6. Since only the iron oxide collected in can be collected and removed separately, it is possible to prevent environmental pollution.

As described above, according to the present invention, the grip front end of the welding fume suction torch is equipped with a rubber material or similar soft suction tube to facilitate arbitrary angle adjustment, and the suction tube front end portion is fitted with a CO2 welding nozzle to slide back and forth. Easy to adjust distance by constructing suction nozzle (2), which effectively absorbs welding fumes and harmful gases generated by various angles due to operator's working method and positional change, thereby effectively reducing By separating and filtering harmful gas, it improves the worker's health and improves the working environment and extends the life of the filter device, which is very economical.
