Description:FIELD OF INVENTION:
[001] The present invention generally relates to the portable fume extractor. More specifically, the present invention relates to the portable fume extraction device tailored for the shipbuilding industry which efficiently removes the hazardous gases and fumes generated during various operations such as welding, cutting, and grinding.

BACKGROUND OF THE INVENTION:
[002] Shipbuilding processes involve various operations such as welding, cutting, and grinding, which generate hazardous gases and fumes. These emissions pose a significant threat to the health and safety of workers and can have adverse environmental effects. Without adequate ventilation and fume extraction, workers face respiratory issues and long-term health problems. Additionally, uncontrolled emissions contribute to air pollution, impacting not only the shipyard but also surrounding communities and ecosystems. Thus, effective control measures are essential to safeguard both worker health and environmental quality in shipbuilding operations.
[003] Traditional fume extraction systems used in shipyards are often characterized by their heavy weight, high noise levels, and the need for additional riggers to move them to desired locations.
[004] CN108817738B describes a movable welding smoke exhaust device, which belongs to the technical field of welding accessory equipment and comprises a smoke exhaust pipeline and air exhaust equipment for exhausting smoke to the outside, wherein the tail end of the smoke exhaust pipeline is blocked, the other end of the smoke exhaust pipeline is connected with an air inlet of the air exhaust equipment, a plurality of smoke exhaust branch pipes are arranged on the smoke exhaust pipeline, one ends of the smoke exhaust branch pipes are communicated with the smoke exhaust pipeline, and the other ends of the smoke exhaust branch pipes are provided with dust collection hoods; and a traveling mechanism is arranged below the smoke exhaust pipeline.
[005] CN101157089B describes a dust collector is provided to collect fume generated during an arc welding operation, oil content and the sand and dust etc. that produce during by the fine solid particle of generations such as cutting processing machine, grinding machine and fog (mist), by road sweeper cleaning road surface and the dust collect plant of recovery and the lightweight dust-like that does not have viscosity that produces during with the trickle dust that in the process of the edible materials of producing flour etc., produces, processing plastic, paper, timber are the dust collect plant of object. The dust collector comprises a collection unit with a suction pipe and a roots blower for expelling air. Within the unit, a rotational shaft supports a rotary filter featuring a cylindrical porous core wrapped in filter material folded into a continuous zigzag shape. An air blower nozzle cleans the filter by directing pressure air in reverse, and a recovery bag collects removed dust.
[006] The aforementioned prior art facilitates dust and fume extraction in industrial settings, but they have limitations in capturing particles of various sizes effectively, the given prior arts may not be optimized for capturing welding fumes of varying particle sizes and do not offer the same level of maneuverability and specificity needed for the dynamic and space-constrained environment of shipbuilding,
[007] Therefore, there is a need for portable fume extractor which addresses the shortcomings of prior arts with a more focused and user-friendly design tailored for the shipbuilding industry.
OBJECTS OF INVENTION:
[008] The main object of the present invention is to significantly reduce the weight of the fume extractor compared to traditional models, facilitating easy handling and maneuverability by a single person.
[009] Another object of the present invention is to provide a portable fume extractor that minimizes vibration and noise levels, creating a more comfortable working environment and reducing potential health risks for workers.
[010] Another object of the present invention is to provide a portable fume extractor that offers stability and prevents movement during operation, ensuring safety and preventing accidents in the dynamic environment of warship construction.
[011] Yet another object of the present invention is to provide a portable fume extractor that enables easy movement and rapid deployment to various locations within the shipyard, improving operational efficiency and flexibility.
