Abstract
An automatic powder spraying system belongs to the technical field of spraying devices. The automatic powder spraying system comprises a spraying bin, a multi-tube cyclone separator and a filter. The input end of the multi-tube cyclone separator is connected with the spraying bin, and the output end of the multi-tube cyclone separator is connected with the filter. The spraying bin comprises a bin casing, and a material inlet and a material outlet are arranged at two ends of the bin casing respectively. Spiral generators are installed on the material inlet and the material outlet respectively. Each spiral generator comprises an outer casing and an inner casing which are coaxial. Powder inlet tubes are arranged on the outer casings and communicated with the spraying bin. The automatic powder spraying system spirally sprays workpieces. Compared with direct spraying of the traditional spray guns, spiral spraying can offset the effect of gravity as far as possible and enables the surfaces of the workpieces to be evener. The automatic powder spraying system is more applicable to spraying of cables and other strip-shaped objects. During spraying, the workpieces only need to move laterally without rotating, thereby omitting chain locks for hanging the workpieces and rotating devices for rotating the workpieces adopted by the traditional spraying system.

Described filter 300 is arranged on the output 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 output 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 compressed air is derived finally by Venturi tube 304, and malleation filter bag 316 being formed to moment is impacted, and realizes 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 in falling " V " shape.Transponder 309 is fixed with below described injection tube 303.Described transponder 309 has been threaded screw rod 310.Described screw rod 310 two ends are rotationally connected with locating rack 313.Described screw rod 310 one end connects gearbox 311, and described gearbox 311 is arranged on the output 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 gearbox 311.Now, transponder 309 along screw rod 310 direction action, thus drives injection tube 303 action on guide rail 308, and Venturi tube 304 is positioned at assigned address.
Porous plate 315 is provided with above described middle casing 314.Filter bag 316 is provided with in described middle casing 314.Described filter bag 316 is perpendicular to porous plate 315 and each filter bag 316 corresponds 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, expand suddenly flow velocity because of gas volume and suddenly reduce, dust sinks under the effect of own wt, and remaining particle 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 constantly increases, 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, is ejected into corresponding Venturi tube 304 by each winding-up mouth of injection tube 303.Gases at high pressure from Venturi tube 304 spray after, induce and drive the surrounding air of several times to enter filter bag 316, filter bag 316 moment is caused sharply to expand, because the percussion of reverse impulse air-flow disappears very soon, filter bag 316 sharply shrinks again, such expansion, shrink, the long-pending unnecessary grit be attached on filter bag 316 outer wall is fallen by cleaning, filter bag 316 is cleaned.This filter 300 sieves powder ability by force, and sieve powder particles is little.
Cleaning due to filter bag 316 is that row one row carry out, and does not cut off and needs the air containing powder to be processed, so in the process of cleaning, the disposal ability of filter 300 is constant.
The secondary recovery mechanism that the present invention adopts multicyclone 200 and filter 300 to form, makes the collection of powder more complete, higher to the organic efficiency of ultrafine dust.
The present invention is illustrated according to embodiment, and under the prerequisite not departing from present principles, this device can also make some distortion and improvement.It should be pointed out that and all drop on the technical scheme that all employings are equal to replacement or the mode such as equivalent transformation and obtain in protection scope of the present invention.
