[background technology]
At present, coating process is to be used for the corrosion-resistant and most economical effective method of decoration of automobile, and the priming before the application directly affects the service life and the decorative effect of coating, need preliminary treatment before the priming through paint base product line, its objective is and remove all impurity that are coated with outside the part formation thing, soldered ball welding slag for example so that the good substrate that is fit to be coated with reload request to be provided, thereby guarantees that coating has good Corrosion Protection and decorate properties.As seen preliminary treatment is big to the influence of whole coating quality.
Existing vehicle paint base product line pretreating process is: artificial prerinse-pre-degreasing-degreasing-washing-Biao accent-phosphatization-washing-RO/DI washing.Artificial prerinse in its step is meant with manually normal temperature current high pressure being flushed in and is coated with on the part, to remove the impurity such as soldered ball welding slag that are coated with above the part.This cleaning method need be arranged artificial station, has increased cost of labor, has also wasted water resource simultaneously, and the effect of removing the soldered ball welding slag in addition is also not obvious.
[summary of the invention]
Pre-cleaning method when having the vehicle paint base product line preliminary treatment now in order to solve is manually normal temperature current high pressure to be washed away to be coated with part, the effect and the unconspicuous technical problem that have increased cost of labor, wasted water resource and removed the soldered ball welding slag, but the invention provides a kind of mechanization prerinse and be coated with part, need not manually-operated, thereby reduced cost of labor, saved water resource and obviously improved pretreated method of vehicle paint base product line and the device thereof that removes the effect of soldered ball welding slag.
The present invention solves the technical scheme that existing technical problem adopts: provide a kind of vehicle paint base product line pretreated method, it comprises the steps: A: prerinse; This steps A may further comprise the steps again: A1: open nozzle ejection and go out current; A2: will be coated with part and move around described nozzle according to curved track, the current flushing that is gone out by this nozzle ejection is coated with part; A3: the waste water after the flushing is handled via discharge of wastewater mechanism.
The pretreated further improvements in methods of the present invention are that it is further comprising the steps of after steps A: B: pre-degreasing; C: degreasing; D: washing; E: table is transferred; F: phosphatization; G: washing; The H:RO/DI washing;
The pretreated further improvements in methods of the present invention are that its steps A 3 may further comprise the steps: A31: the belt filter of the described discharge of wastewater of waste water process mechanism is removed impurity; A32: the waste water of removing behind the impurity releases via the outlet of described discharge of wastewater mechanism.
The pretreated further improvements in methods of the present invention are that employed current are hot water in the steps A 1.
The pretreated further improvements in methods of the present invention are that employed current derive from the waste water that needs the overflow discharging in the steps A 1.
The present invention solves the technical scheme that existing technical problem adopts: provide a kind of vehicle paint base product line pretreated device, described pretreated device comprises water spraying mechanism, cell body and discharge of wastewater mechanism thereof; Described water spraying mechanism is located at the top of described cell body, is convenient to flushing under the current direction; The top of described cell body comprises a flat V-arrangement open slot, is convenient to be coated with part and does curved moving along described flat V-shaped groove; Establish a delivery port in the bottom of described cell body, described discharge of wastewater mechanism is corresponding to described delivery port.
The further improvement of the pretreated device of the present invention is that described water spraying mechanism comprises nozzle and connects the jet pipe of described nozzle; What described nozzle ejection went out is hot water;
The further improvement of the pretreated device of the present invention is, described nozzle be positioned at described flat V-shaped groove directly over.
The further improvement of the pretreated device of the present invention is that the side angle of inclination of described flat V-arrangement open slot can be 30 °.
The further improvement of the pretreated device of the present invention is, described discharge of wastewater mechanism comprises that one is used for the belt filter of impurity screening and the outlet of waste discharge thereof.
Compared to prior art, the beneficial effect of pretreated method of vehicle paint base product line of the present invention and device thereof is: when adopting nozzle ejection hot water, be coated with part and do curved moving around this nozzle; Because the current of nozzle ejection are downward, be coated with part do curved when mobile its flushing surface can produce an acute angle with water (flow) direction so that the soldered ball welding slag dashes from being coated with part.In addition, adopt the hot water injection, the consumption of the normal temperature current of prior art flushing can minimizing chemicals can reduce the pollution of chemicals to environment so relatively; The hot water source who uses needs the waste water of overflow in producing, also saved clean water stream; Waste water after the flushing discharges through discharge outlet after removing the soldered ball welding slag through belt filter again, has reduced the pressure that removes soldered ball welding slag device in the follow-up blowdown work.
[description of drawings]
Fig. 1 is the structural representation of the pretreated device of the present invention.
[specific embodiment]
The present invention is further described below in conjunction with specification drawings and specific embodiments.
