Problems solved by technology

[0004] Due to its technological characteristics, umbrella-shaped wind hoods are generally used in robot automatic stations. However, the umbrella-shaped wind hoods currently used are single-layer wind hoods, which have poor collection effect of welding fume and difficult adjustment of air volume and wind speed. When the station is changed poor regulation

Embodiment 1

[0026] In order to improve the air quality in the production area and improve the operating environment for workers, the automobile welding workshop has upgraded the air supply and exhaust system of the workshop to treat the smoke and dust generated by welding. .

[0027] The final detection is required to achieve the effect:

[0028] There is no obvious smoke and dust accumulation in the lower area of ​​the workshop above the 4.5m floor to the roof space.

[0029] Welding fume (total dust)≤2.0mg / m 3 .

[0030] Ozone≤0.3mg / m 3 ;

[0031] Nitrogen dioxide≤5mg / m 3 ;

[0032] Carbon monoxide content (non-plateau) ≤ 20mg / m 3 ;

[0033] Grinding wheel dust ≤ 8mg / m 3 ;

[0034] Manganese and its inorganic compounds (as MnO2)≤0.15mg / m 3 ;

[0035] Zinc oxide≤3mg / m 3 .

[0036] The smoke and dust emission value discharged outside the workshop is ≤120mg / m 3 .

[0037] In order to meet the above requirements, the whole welding fume treatment system was optimized, among w...

Abstract

The invention discloses a double-layer fan cover of an automatic station welding smoke dust treatment system of a welding workshop robot. The fan cover comprises a smoke dust collecting surface, a side surface and a smoke dust gathering surface, the smoke dust collecting surface and the smoke dust gathering surface are respectively of an umbrella-shaped structure, and the smoke dust collecting surface and the smoke dust gathering surface are arranged in parallel. The smoke dust collecting surface and the smoke dust gathering surface are connected by the side surface, in order to adapt to the automatic station welding smoke dust treatment system of the welding workshop robot, the fan cover has the main functions of collecting the welding smoke dust and preventing the welding smoke dust from diffusing, and uniformly distributed dust collection holes are larger and more uniform in station covering area. The welding smoke dust can be better collected. The internal space of the fan cover on the two sides can effectively gather the smoke dust and guide air distribution, so that the smoke dust is completely collected. The size of the fan cover is divided in a modularized mode, the fan cover can adapt to stations of different sizes, and production and machining are more convenient.

Description

technical field [0001] The invention relates to the technical field of flue gas purification, in particular to a double-layer hood for a robot automatic station welding fume treatment system in a welding workshop. Background technique [0002] The main pollutant in the welding workshop is welding fume. The main methods of welding fume control are: natural ventilation, roof or side wall exhaust, local ventilation, stand-alone purification of welding fume at the station, central fume purification system, overall dust removal of the workshop, etc. . [0003] Among them, the local exhaust system is mainly composed of wind cover, air duct, fan unit dust removal and purification equipment, etc. The perfect local exhaust system can meet the requirements of labor protection and also meet the requirements of environmental protection. The hood is a key component of the local exhaust system. Usually the welding shop uses side windshields and umbrella windshields. The side windshiel...
