Description
Technical field
The present invention relates to the technical field of spraying auxiliary equipment, a kind of specifically waste gas recovery on spraying process
System.
Background technology
Spraying process often produces substantial amounts of waste gas in process, contains substantial amounts of coating particles in waste gas, it is not
Can only suck in human body influences the health of operating personnel, and can be deposited in processing instrument and auxiliary equipment and cause instrument
Damage.There is also detaching caused waste gas in spraying process by way of exhaust fan in existing technology, but due to spray
The coating viscosities of painting are big, high strength after curing, therefore are difficult to clear up when being adhered on fan blade, so of the prior art
Blower fan generally requires frequently to carry out cleaning and maintenance blade, while clears up that difficulty is big, and directly changes the cost mistake of fan blade
Height, it is unfavorable for the popularization of manufacturing enterprise.Although applicant has also applied for a kind of gas recovery method of spraying coating line on the same day, its
The scheme of method is merely given as, the not improvement of installation to structure and its part etc. is not directed to, so there is still a need for
A set of practicable structure technology scheme.
The content of the invention
