Description
Technical field
The utility model is related to a kind of electrostatic spraying device of powdery paints, i.e., a kind of electrostatic spraying is given up powder reclaiming device.
Background technology
Principle of Electrostatic Painting is to make powdery paints absorption on workpiece using corona discharge phenomenon.Its process is powdery paints
Spray gun is admitted to by compressed air, in spray gun front end added with high-pressure electrostatic, due to corona discharge, is produced in its vicinity intensive
Electric charge, when powder is sprayed by rifle mouth, forms powered coating particle, in the presence of electrostatic force, is drawn onto opposite polarity with it
Workpiece gets on.As the powder being sprayed on workpiece increases, charge buildup is also more, when powder reaches certain thickness, due to production
Raw electrostatic repulsion, does not just continue absorption, so that whole workpiece obtains certain thickness powder coating, then by heating
Make powder melts, levelling, solidification, i.e., hard film is formed in workpiece surface.
In electrostatic spray process due to workpiece discontinuous and powder itself quality, and spraying stroke influence, always
Have amount of powder to fail to be landed by absorption of workpieces, these powder can be with recycling, but to reclaim in time, prevent by
Moisture knot block.When reusing, to sieve and screen out impurity and caking, the most important point is can not be the powdery paints list of recovery
Solely use, but the powdery paints of recovery is mixed to stir in new powdery paints used, adsorption effect is used alone
It is bad.
The powder recovering device that current China powder spray is generally used is broadly divided into two classes：The first kind, secondary recovery
Device, it is represented as cyclone separator plus cloth bag retracting device；Equations of The Second Kind, one-level retracting device, it is represented as candle filter.
Two kinds of retracting devices all have weak point in use.The first kind, due to the recovery effect of the cyclone separator of use
Rate is limited so that the thinner powder of a part is lost in secondary recovery device cloth bag, the attritive powder gathered when cloth bag surface
Layer has reached certain thickness, and making the permeability of filter cloth significantly reduces, and causes whole recovery system resistance increase；Equations of The Second Kind,
Candle filter retracting device, filer element type and cloth-bag type are the difference of filtering material, and its work principle of filter is identical, thus filter
Core type reclaims and equally exists all shortcomings of above-mentioned cloth bag.
The content of the invention
The purpose of this utility model is to provide a kind of useless powder reclaiming device of electrostatic spraying simple in construction, not blocking up dressing sieve.
Above-mentioned purpose is realized by following technical scheme：A kind of useless powder reclaiming device of electrostatic spraying is developed, including by powder
Screen cover（1）, locking device（2）, elastic support（3）, dressing sieve base（4）, let out tube cell（5）, powder retrieving pipe（6）, dressing sieve（7）Composition
Vibratory sieve（8）, frame（9）, vibratory sieve motor（10）, fluidizing bucket（11）, it is characterized in：Described dressing sieve（7）It is Double Layer Circular
Dressing sieve, upper sieve（12）Aperture is less than lower floor's sieve（13）Aperture, levels sieve passes through locking device（2）It is fixed together,
Upper sieve（12）And lower screen（13）Between be equipped with dredge（14）.
The dredge（14）It is hairbrush above and below being arranged on screen diameter direction（15）, hairbrush is by being fixed on lower floor up and down
Hairbrush motor on sieve（16）Driving rotation.
The dredge (14) is to be arranged symmetrically two blast pipes into 0-30 degree directions with tangent to periphery（17）.
The dredge is to spend directions into 0-30 in tangent to periphery to be arranged symmetrically two blast pipes（17）, in screen diameter
Hairbrush above and below arrangement on direction（15）.
Described locking device（2）Can be bolt and nut or easy-to-mount snap ring.
The beneficial effects of the utility model are：The hairbrush above and below arrangement in the diametric(al) between sieving up and down（13）, and by
Motor（14）Driving rotation, can remove above and below compass screen surface bond dusty spray, particularly be intermittently passed through compressed gas, blow logical
Levels sieve sieve aperture.Improve powder by property, improve the useless powder rate of recovery.It is simple in construction, strong adaptability.

Embodiment
The design of the utility model always be between levels sieve install one can remove above and below compass screen surface bonding powder,
Make sieve aperture unobstructed, so as to improve separation, recovering effect.Two kinds of embodiments are introduced below in conjunction with the accompanying drawings.
The first embodiment：Fig. 1 Fig. 2 Fig. 3 introduces a kind of useless powder reclaiming device of electrostatic spraying, including by powder sieve cover 1, locking
Device 2, elastic support 3, dressing sieve base 4 lets out tube cell 5, powder retrieving pipe 6, the vibratory sieve 8 that dressing sieve 7 is constituted, by elastic support 3
Hold in frame 9, the useless powder sent by powder retrieving pipe 6 enters in the powder sieve cover 1 of vibratory sieve upper end and fallen on dressing sieve 7, in vibration
In the presence of motor 10, the powder that gives up enters fluidizing bucket 11 after new powder is mixed in bucket by the lower screen 13 of upper sieve 12 through letting out tube cell 5
Sprayed again.
The treating capacity of vibratory sieve 8 directly affects the rate of recovery of useless powder, and treating capacity is big, and the rate of recovery is high；The treating capacity of vibratory sieve 8
Be decided by effective percent opening of sieve aperture, effective percent opening is bigger, material it is better by property, treating capacity is bigger.In reality
In, due to factors such as air humiditys, these powder can cause effective percent opening of sieve to reduce（That is sieve pore blockade）, its because
Two kinds are have, one kind is kindred effect, refer to the blocking of the particle insertion sieve aperture formation close with sieve aperture；Also one kind is
Pile up effect, mostly powder toughness or the sieve pore blockade caused by electrostatic mutually adsorbs generation accumulation, reunited.
Due to being mounted with to remove the dredge 14 for being bonded in powder on compass screen surface between upper sieve 12 and lower screen 13, i.e., on
Lower hairbrush（15）, rotated under the driving of hairbrush motor 16, brush falls to be bonded in the powder of levels compass screen surface, overcomes powder
Kindred effect and pile up effect, sieve effective percent opening increase, powder is passed through levels sieve aperture.
Second of embodiment：As shown in Figure 4, Figure 5, in upper sieve（12）And lower screen（13）Between the removal installed be bonded in
The dredge 14 of powder on compass screen surface, be with levels sieve tangent to periphery direction into 0-30 degree directions be arranged symmetrically two air intakes
Pipe（17）, compressed gas is intermittently passed through, annular airflow, intermittent time manual control is formed.Compressed gas, which can be blown off, is bonded in sieve
Powder on face, blows logical levels sieve sieve aperture, improves the permeability of sieve.
The third embodiment：As shown in Figure 6, Figure 7, the removal installed between upper strata sieve 12 and lower floor's sieve 13 is bonded
The dredge 4 of powder is the rotatable hairbrush up and down arranged in existing diametric(al) on compass screen surface（15）, and in upper sieve
（12）And lower screen（13）Between with tangent to periphery direction into 0-30 degree directions be arranged symmetrically two blast pipes（17）, using hair
Brush roll brush falls to be bonded in the powder of compass screen surface, and compressed gas further blows sieve sieve aperture above and below logical, and the two acts on, changed significantly simultaneously
It has been apt to the permeability of sieve, has improved the rate of recovery of useless powder.
