Description
Technical field
The present invention relates to a kind of spray equipment, the device of the sprayed with fluorescent powder of the use in especially a kind of flat-panel monitor manufacture process, specifically a kind of fluorescent powder constant-temperature and constant-pressure spraying device of shadow mask plasma display.
Background technology
As everyone knows, in SMPDP fluorescent powder jet printing technology,, in the ethanol slurry, easily precipitate because the proportion of fluorescent material is bigger.In spraying process, if do not keep certain mixing speed, the uniformity of slurry to be difficult to guarantee.In case the fluorescent material precipitation is very easily stopped up spray gun.And temperature is bigger to the viscosity influence of slurry, and spray gun is wanted to obtain best jeting effect, must obtain under the constant situation of viscosity, therefore, keeps temperature constant most important.In addition, the feed of spray gun how much, influences bigger to coating layer thickness, uniformity.Because in spraying process, liquid level is along with the carrying out of spraying, liquid level can reduce gradually, and it is big that the difference in height of spray gun and liquid level can become gradually.Because fluorescent powder paste material proportion is bigger, cause the flow in the feeder sleeve inconsistent, the uniformity of coating is difficult to guarantee after the lance ejection.
Summary of the invention
The objective of the invention is in the existing fluorescent powder jet printing owing to a series of problems such as temperature, pressure, stirring cause the uneven problem of spraying, design the fluorescent powder constant-temperature and constant-pressure spraying device of the shadow mask plasma display that a kind of constant temperature and pressure stirs.
Technical scheme of the present invention is:
A kind of fluorescent powder constant-temperature and constant-pressure spraying device of shadow mask plasma display, comprise spray gun 1, slurry tank 9, slurry tank 9 is connected with charging aperture 10, exhaust outlet 11 and discharge gate 12, the charging aperture of spray gun 1 links to each other with compressed air gas source 8 and slurry tank 9 respectively, the tank skin that it is characterized in that described slurry tank 9 is a double-decker, be connected with liquid medium in the tank skin, this liquid medium links to each other with heat-exchange system 2; Described compressed air gas source 8 communicates with the space of liquid upper in the slurry tank 9 by tracheae, and constant pressure valve 6 is housed on this tracheae; Shaft 3 also is installed in slurry tank 9, and this shaft 3 is driven by stirring motor.
Described slurry tank 9 also is connected with the Pressure gauge 7 of pressure in the thermometer 4 that is used for measuring the jar slurry temperature, the liquid level gauge 5 that reflects liquid level height in the jar and the reflection jar.
Beneficial effect of the present invention:
The present invention can make the temperature of fluorescent powder paste material keep constant by heat-exchange system, thereby liquid viscosity is remained unchanged; By constant pressure valve, make the pressure that acts on liquid level keep constant, thereby guarantee that fluid pressure is constant in the feeder sleeve, reach stability of flow.Thereby make and use spray equipment of the present invention that the performance indications of nozzle are required to reduce greatly, greatly reduce purchase cost.Control of the present invention simultaneously is simple, need not the control of very complicated, has reduced the control failure factor, has improved production efficiency.To other spraying industry, particularly temperature, flow-control there are the liquid spray of requirement, all can adapt to, have wide range of applications!
