Description
Technical field
The present invention relates to the tools used when a kind of coating sprays, and gathering formula painting spraying device more particularly to one kind.
Background technology
Coating is common decorative material for wall surface during we live, and beautifies our life, former coating is all to pass through brush
Son is coated on wall, and with the appearance of scientific and technological progress and automation spray painting apparatus, currently the majority coating is all to pass through height
Press device sprays on wall, has many advantages, such as that efficient, coating uniform is fine and close, apparent consistency is high with traditional map brushing, however
There are also deficiencies for spraying, and in spraying, high pressure coating, which is atomized, rushes at wall, and the air-flow that the coating of high-pressure injection drives encounters wall
Deflecting around after wall, most of atomised coating are contacted with metope and are adhered on the wall, the smaller atomizing particle meeting in part periphery
It is taken away by four scattered air-flows, not only wastes coating, can also fall on and pollute the position that need not be sprayed, while flying mist to spraying
The harm of personnel is also big, these problems are still up for solving.
Invention content
To solve the above-mentioned problems, the present invention provides one kind gathering formula painting spraying device, it is possible to implement connection and nothing
Damage dismounting.
The technical solution adopted by the present invention is：One kind gathering formula painting spraying device, it is characterised in that including core pipe and spray
Head, core pipe are hollow tube, and core pipe rear end is connected with suction mechanism, and core pipe is equipped with the boss radially outward stretched, and nozzle is equipped with
First half and latter half of, nozzle is latter half of equipped with the casing being inserted in by core pipe front end, and casing leading portion diameter is less than back segment diameter shape
At step, casing rear end is connect with boss, and outside of sleeve is equipped with possesses the annular sleeve of spacing with it, and annular sleeve rear end and casing are close
Connection is closed, annular sleeve is connected with high pressure coating interface, and annular sleeve front end opens, and nozzle first half is annular, between nozzle first half
Gap coordinates outside casing leading portion, and casing front end is connected through a screw thread the nut that nozzle first half is pressed to step, before nozzle
Half portion outer rim and intermarginal formation annular spray gap in casing front end.
Further, it by screw thread or is snapped connection between described sleeve pipe rear end and boss connection.
Further, the trepanning being gradually reduced backward is distributed on the core pipe leading portion side wall.
When the present invention sprays, nozzle ring ejects the mist of a hollow substantially taper, and the coating of high-pressure injection drives
Air-flow encounter wall and generate collision, due to generating a negative pressure in core pipe front end, originally the scattered atomizing particles in periphery four move
Path changes, and is changed to inwardly move with air-flow, forms a spray regime gathered, and four scattered atomizing particles greatly subtract
Small, equipment recycling can be recovered by filtration by peripheral hardware in the winged mist that core pipe air-flow is taken away, and environmental pollution is small, and paint waste is few,
Reduce the harm to spraying personnel.
Description of the drawings
Fig. 1 is overall schematic of the embodiment of the present invention.
Fig. 2 is schematic cross-sectional view of the embodiment of the present invention.
Reference numeral:1 core pipe；2 nozzles；3 boss；4 casings；5 steps；6 annular sleeves；7 high pressure coating interfaces；Before 8 nozzles
Half portion；9 nuts；10 annular spray gaps；11 elastic sealing gaskets；The outer inclined-plane of 12 nozzle first halfs；The outer inclined-plane of 13 annular sleeves.
Specific implementation mode
The embodiment of the present invention is as shown in Figure 1, 2, this is gathered formula painting spraying device and is equipped with core pipe 1 and nozzle 2, during core pipe is
Blank pipe, core pipe rear end are connected with suction mechanism, and suction mechanism can be wind turbine or the vacuum tank with vacuum pump, be produced in core pipe front end
Raw negative pressuren zone, negative pressure, which is adjustable to, effectively reduces winged mist diffusion, and core pipe is equipped with the boss 3 radially outward stretched, nozzle
Equipped with first half and latter half of, nozzle is latter half of equipped with the casing 4 being inserted in by core pipe front end, and it is straight that casing leading portion diameter is less than back segment
Diameter forms step 5, and casing rear end connect with boss, and the present embodiment is connected through a screw thread, and when implementation, which can also pass through, to be buckled or screw
Connection, outside of sleeve is equipped with possesses the annular sleeve 6 of spacing, annular sleeve rear end and casing airtight connection with it, forms an annular
Coating containment space, annular sleeve are connected with high pressure coating interface 7, and annular sleeve front end opens, and nozzle first half 8 is annular, nozzle
First half clearance fit has good polarization, casing front end has been connected through a screw thread will be before nozzle outside casing leading portion
Half portion presses to the nut 9 of step, nozzle first half outer rim and intermarginal formation annular spray gap 10 in casing front end, is set on step
Flexible gasket 11 makes the spraying gap have adjustability, naturally it is also possible to not use elastic sealing gasket, be directly connected to be formed
Fixed spraying gap, gap injection have directive property, the outer inclined-plane of the nozzle first half in the gap that can be sprayed by composition, interior
Cone angle and the outer inclined-plane of annular sleeve, interior cone angle are arranged, the outer inclined-plane 12 of the present embodiment nozzle first half and annular sleeve it is outer tiltedly
Face 13 is coplanar, angle separated time and the coplanar orthogonal at gap inner cone angle of spraying, and ejects a gradually wide ring-shaped section and ring-shaped forward
Mist, be inside mist it is hollow with core pipe without collision, inside and outside is gradually wide conicoid forward,
When the present invention sprays, nozzle ring ejects the mist of a hollow substantially taper, and the coating of high-pressure injection drives
Air-flow encounter wall and generate collision, due to generating a negative pressure in core pipe front end, originally the scattered atomizing particles in periphery four move
Path changes, and is changed to inwardly move with air-flow, forms a spray regime gathered, and four scattered atomizing particles greatly subtract
Small, equipment recycling can be recovered by filtration by peripheral hardware in the winged mist that core pipe air-flow is taken away, and environmental pollution is small, and paint waste is few,
Reduce the harm to spraying personnel.
When implementation, the trepanning being gradually reduced backward can be distributed on core pipe leading portion side wall, trepanning is distributed along week and axially,
It more they tends to mitigate to air-flow is made.
It is only present pre-ferred embodiments in summary, all equivalent modifications done according to the application and prior art addition are equal
It is considered as the technology of the present invention scope.
