Problems solved by technology

[0002] The smoke exhaust ventilation measures of mobile electric welding machines and electric welding machines with non-fixed station welding operations have always adopted the method of flexible suction arms, so the smoke exhaust ventilation of electric welding operations beyond the range of flexible suction arms is limited, and has not been very good.

Embodiment 1

[0013] Example 1: Main connection relationship:

[0014] The smoke collecting hood 1, the flexible smoking pipe 2, and the Venturi fan 3 are all installed on the movable support 5, and the compressed air telescopic pipe 6 is connected with the Venturi fan 3. The smoke removal system is active, and the power of the fan comes from the compressed air passing through the small nozzles on its metal base to drive or accelerate the air around the smoke collection hood 1 to generate a strong moving airflow. A hose pushed by the compressed air line connects the air supply to the inlet nozzle on the side of the fan base. Therefore, the smoke removal system itself does not consume power. The fume collecting hood 1 is installed at the front end of the system, above the fume outlet of the welding workpiece. The flexible smoking pipe 2 is a flexible pipe connected between the fume collecting hood 1 and the Venturi fan 3. The Venturi fan 3 is connected with the compression The air telesc...

Embodiment 2

[0016] Example 2: When it is necessary to increase the air volume, open the pneumatic booster pump 7 to increase the air intake pressure and increase the outlet air volume.

Abstract

The invention relates to a smoke removal and ventilation equipment for a movable electric welding machine, which is particularly suitable for smoke removing and ventilation for the electric welding machines without a fixed station. The invention aims to provide complementary welding smoke control equipment which can effectively collect and discharge welding smoke produced by a moving electric welding machine without a fixed station, and enables the collection of flue gas generated by movable electric welding machines to be fundamentally improved. The smoke removal and ventilation equipment for the movable electric welding machine comprises an exhaust fume collecting hood 1, a flexible smoke absorption pipe 2, a venturi blower 3, a flexible smoke exhaust pipe 4, a movable bracket 5, a compressed air expansion pipeline 6 and a pneumatic booster pump 7. The smoke removal and ventilation equipment has the following advantages: the smoke dissipating in local areas can be collected movably and flexibly in a large wind volume; the smoke removal and ventilation equipment per se does not increase power consumption; all that is needed is to feed compressed air and the smoke removal and the ventilation equipment for the movable electric welding machine can be utilized.
