Exhaust fume collecting hood for robot and common welding station

Abstract

The invention discloses an exhaust fume collecting hood for a robot and a common welding station. The exhaust fume collecting hood comprises an exhaust fume collecting hood body of a rectangular box type structure, wherein smoke dust recycling holes I are formed in the periphery of the exhaust fume collecting hood body, an exhaust fume collecting cavity is formed in the exhaust fume collecting hood body, and a baffle and a flow equalizing plate are arranged at the top and the bottom of the exhaust fume collecting cavity correspondingly. A through hole is formed in the center of the baffle, a smoke passing pipeline is arranged above the through hole, a plurality of arc-shaped smoke dust recycling holes which are distributed annularly are formed in the flow equalizing plate, the circle centers of the arc-shaped smoke dust recycling holes which are distributed annularly are the same, and a plurality of smoke dust recycling holes II are evenly distributed in the two sides of each arc-shaped smoke dust recycling hole. The exhaust fume collecting hood can meet the requirement for recycling smoke dust and other pollutant gases in a relatively closed limited space when a plurality of stations work at the same time. The exhaust fume collecting hood can collect smoke dust thereunder and can also meet the requirement for recycling smoke dust generated in the relatively closed space and gather both of them together thereupon, thereby recycling the smoke dust uniformly without dead corners.

Description

technical field [0001] The invention relates to the field of fume collection and treatment, in particular to a fume collection hood used for robots and common welding stations. Background technique [0002] Welding fume and other dust-containing pollutant gases pollute the air environment and affect the occupational health of employees. In addition, according to the relevant national environmental protection regulations and policies, the state strongly supports the innovation and improvement of environmental protection equipment to meet the new emission standards. [0003] At present, the fume collection methods of the welding station mainly include fixed fume collection hoods, mobile fume collection hoods, and rotating fume collection hoods. The above smoke collection methods are mainly suitable for the collection of smoke and dust at one or two workstations in the non-confined space in the production workshop. However, there are certain defects in the absorption of smoke...
