Specific embodiment
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not limit Qualitatively it is impossible to protection scope of the present invention is limited with this.
A kind of double atomization catches electrostatic japanning room, including an electrostatic japanning room 7, installs electrostatic in this electrostatic japanning room 6, it arranges main water curtain plate 4 and side water curtain plate 12 in electrostatic japanning room inwall, in electrostatic painting house-owner's water curtain back even Meet a steam-water separation chamber 14, air-introduced machine 1 is installed above steam-water separation chamber, main water curtain plate bottom is set to inclined-plane bath plate 5, quiet EFI japanning room is connected with steam-water separation chamber by the double atomization coating cloud capturing structure that inclined-plane bath plate lower end connects, this dual mist Change coating cloud capturing structure and include head saw tooth plate 18, water conservancy diversion gullet plate 22 and base plate flow-guiding structure 11, head saw tooth plate lower end is formed with Sawtooth 26, water conservancy diversion gullet plate lower end is formed with sawtooth 27, and head saw tooth plate is arranged on inclined-plane bath plate lower end, and head saw tooth plate one extends Make arc linkage section 16 to be connected with inclined-plane bath plate, water conservancy diversion gullet plate is arranged on the end of arc linkage section, this water conservancy diversion sawtooth Plate one extends makes arc diversion section 15, and head saw tooth plate and its arc linkage section form the first vortex mist with base plate flow-guiding structure Change space 20, water conservancy diversion gullet plate and its arc diversion section form the second swirl atomization space 24 with base plate flow-guiding structure, further Say that arc linkage section is arranged on inclined-plane bath plate lower end by pin 17, water conservancy diversion gullet plate is arranged on arc by pin 23 and connects The end of section, base plate flow-guiding structure is formed with the protrusion diversion section 21 being matched with arc linkage section, this protrusion diversion section and master Gullet plate and its arc linkage section form interference fit, and arc diversion section end is formed with reinforcement 25, and head saw tooth plate and base plate are led Form one-level coating cloud import 19 between flow structure, between water conservancy diversion gullet plate and base plate flow-guiding structure, form two grades of coating cloud imports, arc Shape diversion section end forms aerosol separating opening with base plate flow-guiding structure extended surface 13.Electrostatic japanning room bottom surface setting base plate water conservancy diversion knot Structure.Base plate flow-guiding structure front end arranges preshoot ditch 9, lays preshoot feed pipe 8 in preshoot ditch, and front-flushing ditch passes through guiding tiltedly Face 10 connects to double atomization coating cloud capturing structure.It is provided with overflow launder 3, overflow above main water curtain plate and side water curtain plate Gutter feed pipe 2 is provided with groove.
Medicament current direction one-level coating cloud import of the present invention, due to the effect of air-introduced machine, medicament water is drawn through head saw tooth Because vortex medicament water is broken up into vaporific after plate, form vaporific medicament water meter area and become geometrical progression to increase, to gas Coating cloud in stream forms parcel, enters medicament water after two grades of coating cloud imports with the not wrapped coating cloud of air-flow and is atomized again, To after the second swirl atomization space, remaining coating cloud is all wrapped up substantially, the coating cloud being wrapped up by medicament water by arc guide face Form the medicament aqueous fusion that undershoot and base plate flow-guiding structure extend on bottom surface and close and flow into next procedure from liquid outlet, clean air-flow Bounce-back rises through air-introduced machine and enters next process process.
The present invention improves coating cloud wash degree.Paint spray booth of the prior art is to carry out coating cloud washing using moisture film, washes Wash efficiency causes aerofluxuss still to contain a large amount of coating clouds presence less than 80%, affects the process to gas for the down-stream.The present invention exists The moisture film clashing into liquefaction formation after carrying out prime atomization washing in first swirl atomization space and with arc turning is atomized again Afterwards secondary washing is carried out to gas, Washing ratio can be promoted to more than 98% and greatly improved clean rate.In addition double saw The cleaning being easy to inside can be stirred using articulated manner connecting secondary sawtooth between tooth plate.The advantage of this structure is to overcome Conventional dry electrostatic room leads to waste gas to contain the big defect of paint amount because not having gas scrubbing structure;Compare old-fashioned wet type spray room to adopt Annular return air leads to the relatively low defect that cannot realize atomization washing of wind speed, and this structure adopts monolateral centralized return air system, and return air amount does not increase Plus but at return air inlet, air intake wind speed is high, the requirement of atomization washing can be met.Other this pair of broached-tooth design is for hinge pin joint therefore Easy to loading and unloading, during clear internal paint slag, human users are simple.
The present invention full water curtain flushing structure -- overcome conventional wet electrostatic room bottom tank in a large number amass paint be difficult to lack Point, electrostatic chamber inner space is all coated using cascade in addition to top, and the water surface that electrostatic interior is contacted with coating cloud is all quick The moisture film structure of flowing.Moisture film is made up of the annular water curtain+bottom bath plate two parts around static nozzle, jointly completes side With the collecting function of bottom coating cloud, the current after collection by rely on deadweight come together in vortex generator sentence after an action of the bowels continue coating cloud wash Wash the realization of technique.Because electrostatic room coating cloud injection intensity is far longer than manual spray room, and the larger therefore relatively handss of the paint amount that falls spray Room quantity of circulating water lacquer mistiness degree is high, and steam-water separation chamber's bottom collect cavity easily forms the floating paint unfavorable spray room of slag and transports steadily in the long term OK, therefore this spray room steam-water separation chamber bottom aerosol separating opening ensure not all right lacquering slag in the case of by its volume-diminished extremely 30 seconds pump discharges, from the basic condition eliminating paint slag formation it is ensured that spray room is run steadily in the long term.This electrostatic room is the first By spraying equipment integrated to automatic scummer and spray room, need not the cleaning equipment such as supporting circulating water pool reservoir storage is more external simultaneously follows The little medicament utilization rate of the little therefore chemical feeding quantity of cisterna ambiens is high.Slag-tapping device is automatic running without manual intervention automaticity simultaneously Height, the little operational efficiency of the integral device comprehensive method of investment is high.Simultaneously because reservoir storage is little and does not have gutter and the dresses such as water-retention dosing pond Standby, therefore water saving province medicine operating cost is low.
