Description
Technical field
The present invention relates to the venting of dust explosion explosion resistant structure and antiknock method of powder spraying chamber on a kind of electrostatic powder spraying streamline.
Background technology
Application is the important and critical process of equipment manufacture, because application is related to product appearance, and the work that application is later
Part inconvenience long-distance transportation, general manufacturer solves the application of product all without selection by cooperation processing, therefore most numeral system
Make factory all can in factory building self-built Painting Shop or application workshop section.Due to the continuous improvement of environmental protection standard, many products
Application all employs the Powder Electrostatic Coating Technology of more clean environment firendly to substitute traditional painting technology.
Powder Electrostatic Coating Technology principle is：A high-voltage corona discharge electric field is formed between spray gun and workpiece, works as modeling
Material powder particle is sprayed by gun slot when passing through region of discharge, and just the substantial amounts of electronics of supplementary set, turns into electronegative particulate, in electrostatic
In the presence of attraction, positively charged workpiece is adsorbed to up.When powder is attached to certain thickness, then " the same sex can occur
Repel each other " effect, it is impossible to absorption powder again so that the powder layer thickness of each several part is uniform, then powder after heated baking-curing
Laminar flow Heisei is uniform film layer.Powder Electrostatic Coating Technology flow is as follows：Piece uploading → pre- thermal conducting → electrostatic spraying（Primary coat）
→ hot melt solidification → cooling → lower part.
Because spraying process is intermediate step, preceding road welding sequence and rear road general assembly process are connected, in setting for industrial premises
Timing, Painting Shop often in big factory building among, according to《Code for fire protection design of buildings》GB50016-2014 requirement, in order to
The production classification of whole factory building is not improved, it will usually by Painting Shop or the control of the construction area of application workshop section in complex factories
Within the 10% of overall floorage, meanwhile, often it is arranged in factory building end bay or adjacent for the ease of ventilation and dedusting, Painting Shop
It is middle it is outdoor across.Outside Painting Shop would generally the auxiliary room of outer patch, for arranging the supporting auxiliary equipment of spraying line and computer room etc..
Powder spraying chamber is one of capital equipment of powder electrostatic coating.The dust content of powder spraying chamber can be monitored and controlled,
Make it below explosion limit（Typically it is set to 10g/m3）, while the indoor equipment that dusts uses antiknock device.As long as it is general according to
It is required that having carried out effective monitoring and control to dust concentration, and antiknock device is employed, usual related review activities is considered as setting
Meter meets the requirements.But on stricti jurise, powder spraying chamber is really the project with explosion hazard, with explosion accident in recent years
Take place frequently, indivedual regional requirements must carry out venting of dust explosion anti-explosion design to powder spraying chamber.Because powder spraying chamber is in electrostatic powder spraying flowing water
In line, and streamline is typically arranged in factory building because its special technological process requires, and outside patch has assistance building,
This causes very big difficulty to design.
The content of the invention
It is an object of the invention to overcome above shortcomings in the prior art, and provide a kind of reasonable in design
The venting of dust explosion explosion resistant structure and antiknock method of powder spraying chamber, had both met venting of dust explosion anti-explosion design requirement on electrostatic powder spraying streamline,
The arrangement of electrostatic dusting production line is not influenceed again.
Technical scheme is used by the present invention solves the above problems：Powder spraying chamber on a kind of electrostatic powder spraying streamline
Venting of dust explosion explosion resistant structure, including powder spraying chamber, assistance building and workshop；Assistance building and workshop are adjacent；Powder spraying chamber is located at
In workshop；It is characterized in that：Also include antiknock wall and venting of dust explosion wall；Two sides antiknock wall is by one of region of assistance building
Every getting up, powder spraying chamber and the regional connectivity form a uprising room；Antiknock wall and venting of dust explosion wall surround the surrounding in uprising room, antiknock
Wall is located in workshop and assistance building, and venting of dust explosion wall is located at outside workshop, the exterior wall as assistance building；Pacify in antiknock wall
Equipped with blast-resistant door, explosion relief door is installed on venting of dust explosion wall；The roof of powder spraying chamber uses antiknock roof；Adopt on roof on described region
With venting of dust explosion roof.
Antiknock wall of the present invention is made of concrete.
Venting of dust explosion roof on region of the present invention is made of light material.
Venting of dust explosion wall of the present invention is made of light material.
A kind of antiknock method of the venting of dust explosion explosion resistant structure of powder spraying chamber on electrostatic powder spraying streamline, it is characterised in that：Hair
Raw explosion time, antiknock wall and antiknock roof carry out antiknock, and carry out venting of dust explosion using venting of dust explosion roof and venting of dust explosion wall.
The present invention compared with prior art, has advantages below and effect：The present invention is not influenceing powder electrostatic well
On the premise of the arrangement trend of spraying line, solves the venting of dust explosion anti-explosion design problem of powder spraying chamber.The present invention dexterously uses
The chamber body of one antiknock covers the powder spraying chamber in plant floor, while the region of powder spraying chamber and the assistance building closed on
Connection, venting of dust explosion is carried out using the roof and exterior wall of assistance building.The present invention had both met venting of dust explosion anti-explosion design requirement, and did not influenceed
The arrangement of electrostatic dusting production line, the overall unification of factory building and attractive in appearance is maintained again.
