In spacing ring 6, spacing ring 6 carries out spacing to pull bar 3, prevents inlet air plenum 20 horizontal looseness, impact fluidized plate 21 and powder bucket 2 bottom
The sealing in portion, position-limit mechanism may also be employed other prior arts carry out spacing.The present invention also can arrange ring in the lower surface of powder bucket 2
The groove of shape, installs sealing ring in groove, thus increasing sealing when powder bucket 2 bottom is contacted with inlet air plenum 20.
For improving the automaticity of the present invention, air inlet valve 27, powder valve, charging valve 14, intake valve 19 and pressure maintaining valve 23
All from electromagnetic valve and its control end is electrically connected with control circuit respectively；Pressure-detecting device is pressure transducer, and its signal is defeated
Go out end to electrically connect with control circuit.Control circuit can be selected for PLC control program, its concrete structure, those skilled in the art according to
Interlock requirement can not spend creative work to draw, will not be described here.
Because, during spraying, after clearing up every time, pressurize shell inner surface may retain amount of powder, the powder that every batch uses
The color at end etc. may be different, if retaining more powder in powder bucket, when being cleared up, more powder may be with pressurize housing
The residual powder mixing of inner surface, causes powder to be contaminated it is impossible to reuse.So the present invention opens in the bottom of powder bucket side wall
It is provided with powder outlet, powder outlet is connected with row's tube cell 28 that pressurize housing is stretched out in its end, powder outlet can be multiple, and it is in powder
Uniform ring cloth on the side wall of bucket, row's tube cell quantity corresponding thereto, every row's tube cell arranges row's powder of controllable pipeline break-make
Valve, row's tube cell can contain bucket with former powder and be connected.
During spraying preparation, flour extraction pipe 22 is connected with spray gun, opens air inlet valve 27, makes to reach certain pressure in pressurize housing 1,
And discontinuous opens pressure maintaining valve 23, makes pressure maintaining valve 23 pressure release make pressure in pressurize housing 1 maintain certain pressure, inlet air plenum simultaneously
20 air intake makes powder fluidising, after fluidisation is good, opens spray gun, starts to spray, when in pressurize housing 1, pressure is less than setting value,
Control circuit controls the valve port that pressure maintaining valve 23 connects pipe 24 to open, and wind enters pressurize shell from blast pipe 26 and voltage stabilizing mouth simultaneously
Body 1, now in powder bucket 2, powder was both blown by bottom wind, was subject to the pushing of wind entering from voltage stabilizing mouth again, improved powder from going out powder
Mouth goes out the speed of powder, also improves the powder containing quantity in unit volume simultaneously, improves spraying effect.And the present invention remains pressurize
In housing 1, pressure maintains setting value it is achieved that the constant voltage of powder bucket 2 supplies powder.
When powder is changed in powder bucket 2 cleaning, air inlet valve 27 is closed, and row's powder valve is opened, and the air inlet valve of blow device is opened and purged,
Now driving cylinder is in and treats running status, makes blow device stand purging, most of powder is under the pressure of top wind through row
Tube cell is discharged, and by arranging the setting of tube cell, improves the utilization rate of residual powder in powder bucket, the operation reducing complete equipment becomes
This.After powder cleans out in powder bucket, it is then turned on driving cylinder and is purged up and down.Driving cylinder 15 drives purging room 11 downward
Move and formed simultaneously whirlwind to be purged, now inlet air plenum 20 is moved down under self gravitation effect, and separated with powder bucket 2, and powder is opened
The powder gap that goes out begun between powder bucket 2 and inlet air plenum 20 blows out, and falls pressurize housing 1 bottom, through repeatedly back and forth purging, purging
Device and inlet air plenum 20 return to original position, open powder valve, hole between powder bucket 2 and pressurize housing 1 for the air-flow passes through and blows
Sweep remaining powder herein, simultaneously by the recovery powder blowout in pressurize housing 1 bottom that falls.After reclaiming powder blowout, close powder valve, by
Individual open flour extraction pipe 22, each flour extraction pipe 22 line is cleared up, cleans out, open pressure maintaining valve 23 and carry out pressure release, pressure release is complete
Become, open the charging valve 14 of loading hopper 12, carry out plus powder, powder interpolation finishes, and the present invention is in and treats running status.The present invention
Middle setting purging room 11 moving up and down, inlet air plenum 20 can move up and down with purging room 11, makes between powder bucket 2 and inlet air plenum 20
Form out powder gap it is achieved that the automatic cleaning of powder bucket 2, powder bucket 2 cleans out, you can open flour extraction pipe 22 to flour extraction pipe 22 tunnel
Cleared up, realized the automatic cleaning of the present invention by gas purging.The present invention adopts control circuit to control, and improves the present invention
The simplicity of operation, automaticity improves.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention.Previous embodiment is to the present invention
It has been described in detail, for a person skilled in the art, it still can be to the skill described in foregoing embodiments
Art scheme is modified, or carries out equivalent to wherein some technical characteristics.In every case in the inventive concept scope of the present invention
Within, any modification, equivalent substitution and improvement done etc., it is all contained within protection scope of the present invention.
