Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Automatic powder spraying system, including spray storehouse 100, multicyclone 200 and filter 300;The input of described multicyclone 200 is connected with spray storehouse 100, and outfan is connected with filter 300.
Described spray storehouse 100 includes storehouse shell 101, and the two ends of described storehouse shell 101 are respectively arranged with charging aperture 102 and discharging opening 103.Described charging aperture 102 and discharging opening 103 are mounted on spiral generator 104.Described spiral generator 104 includes shell and inner shell;Inner shell and shell concentric.Workpiece runs through the inner shell of spiral generator 104.Described shell is provided with powder inlet pipe 105.Described powder inlet pipe 105 connects powder cabin.
Powder in powder cabin, enters spray storehouse 100 by powder inlet pipe 105 internal, and under the effect of spiral generator 104, workpiece is carried out spiral spray.Relative to the direct spraying of conventional lance, spiral spray counteracts the impact of gravity as much as possible, to the spraying of surface of the work evenly.Native system is more suitable for the spraying of the isometric bar-shaped object of cable, and in the process of spraying, workpiece has only to translation, it is not necessary to rotate, eliminate in conventional spray system in order to hang the chain lock of workpiece and in order to the rotary apparatus of rotational workpieces.As can be seen here, native system more compact structure, simple operation, production cost is lower.
As preferably, being provided with accumulated powder plate 106 bottom described storehouse shell 101.Described accumulated powder plate 106 is in order to collect the powder settled because of action of gravity.Described accumulated powder plate 106 adopts ventilative structure.Described accumulated powder plate 106 is arranged below ventilation duct 107.Described ventilation duct 107 includes upper plate, lower plate and grid.Described grid is between upper plate and lower plate, and is arranged at the surrounding of ventilation duct 107.Described lower plate is ventilative trellis, and described ventilation duct 107 connects blast pipe 108.
Compression air enters ventilation duct 107 by blast pipe 108, and by passing through accumulated powder plate 106 after the grid of ventilation duct 107 equably, thus driving the powder on accumulated powder plate 106 up, the powder preventing a part on the one hand continues sedimentation, also powder part settled on the other hand, from newly taking back spraying area, improves the utilization rate of powder spray.
As preferably, as it is shown in figure 1, described spray storehouse 100 can be the cylinder of hollow, or as in figure 2 it is shown, described spray storehouse 100 can be the cuboid of hollow.
Described multicyclone 200 includes suction guide plate 201, cyclone separator 202 and collection powder case 203.Described suction guide plate 201 arranges and is arranged in storehouse shell 101.Described suction guide plate 201 is connected with cyclone separator 202 pipeline.Described cyclone separator 202 has 9, and parallel with one another.Described collection powder case 203 is arranged on cyclone separator 202 lower end.Present invention employs the design of the convulsion of uniqueness, it is ensured that in spray storehouse 100, air-flow is steady, and upper powder is high, saves powder.
Described filter 300 is arranged on the outfan of multicyclone 200.Described filter 300 adopts syllogic integrative-structure, is upper box 301, middle casing 314 and lower box 317 from top to bottom successively.
Described upper box 301 is provided with pulse compressor 302, injection tube 303 and Venturi tube 304.Described pulse compressor 302 is horizontally disposed with and is positioned at above injection tube 303.Described injection tube 303 is horizontally disposed with and below injection tube 303, spaced set has one group of Venturi tube 304.Described upper box 301 top is provided with cover plate 305.Described pulse compressor 302 and injection tube 303 are parallel to each other, and the outfan of pulse compressor 302 is connected with the input of injection tube 303.Described Venturi tube 304 and injection tube 303 are conducted.Pulse compressor 302 opens vent plug, sends air pulse to injection tube 303, and compression air is finally derived through Venturi tube 304, and the malleation that filter bag 316 is formed moment is impacted, it is achieved deashing.
As preferably, described injection tube 303 two ends are all located on support 306, are provided with a pair guide wheel 307 bottom described support 306.Described guide wheel 307 is arranged in guide rail 308, and as preferably, described guide rail 308 upper surface is inverted " v ".It is fixed with transponder 309 below described injection tube 303.Described transponder 309 is threaded screw rod 310.Described screw rod 310 two ends are rotationally connected with locating rack 313.Described screw rod 310 one end connects change speed gear box 311, and described change speed gear box 311 is arranged on the outfan of servomotor 312.Described screw rod 310 is parallel to each other with guide rail 308.
Servomotor 312 action, drives screw rod 310 to rotate by change speed gear box 311.Now, transponder 309 is along screw rod 310 direction action, thus driving injection tube 303 action on guide rail 308, Venturi tube 304 is positioned at appointment position.
Described middle casing 314 is provided above porous plate 315.It is provided with filter bag 316 in described middle casing 314.Described filter bag 316 is perpendicular to porous plate 315 and each filter bag 316 corresponding to the corresponding hole on porous plate 315.Described lower box 317 is arranged on below middle casing 314, and lower box 317 is in turbination;The bottom of described lower box 317 is provided with ash-discharging device 318.
When the air containing powder enters filter 300, expanding suddenly flow velocity because of gas volume and suddenly reduce, dust sinks under the effect of own wt, and remaining granule is arrested in filter bag 316 outer wall under the effects such as the screening of filter bag 316, collision and diffusion.Purified gas is discharged by upper box 301.When the dust being arrested in filter bag 316 outer wall is continuously increased, the resistance of filter 300 increases, in order to ensure that the draught control of filter 300 is in the scope limited, pulse compressor 302 sends pulse of air, each winding-up mouth of injection tube 303 be ejected into the Venturi tube 304 of correspondence.Gases at high pressure from Venturi tube 304 spray after, the surrounding air inducing and driving several times enters filter bag 316, filter bag 316 moment is caused sharply to expand, owing to the percussion of reverse impulse air-flow quickly disappears, filter bag 316 sharply shrinks again, such expansion, shrinking, make the long-pending unnecessary grit being attached on filter bag 316 outer wall be cleaned by falling, filter bag 316 is cleaned.This filter 300 sieves powder ability by force, and sieve powder particles is little.
Owing to the cleaning of filter bag 316 is that string string carries out, it is not turned off needing the air containing powder to be processed, so in the process cleaned, the disposal ability of filter 300 is constant.
The present invention adopts multicyclone 200 and the secondary recovery mechanism of filter 300 composition so that the collection of powder is more complete, and the organic efficiency of ultrafine dust is higher.
Present invention embodiment is illustrated, and under the premise without departing from present principles, this device can also make some deformation and improvement.It should be pointed out that, that all employings are equal to the technical scheme that the modes such as replacement or equivalent transformation obtain, all fall within protection scope of the present invention.
