Abstract
The invention provides a drying furnace for a plasma display, comprising a heater, an air inlet arranged at the upstream part of the heater and an air exhaust port arranged at the downstream part of the heater; the drying furnace for the plasma display further comprises a filter which is arranged at the position of the air inlet, and a connecting pipeline of which one end is communicated with the air exhaust port and the other end is communicated with the air inlet by the filter; the invention further provides a drying method of the plasma display, comprising the following steps: the plasma display to be dried is placed in the drying furnace for the plasma display, hot air heated by the heater of the drying furnace is blown to the plasma display to be dried, and the hot air takes sway the volatile carrier in the slurry and then is exhausted from the air exhaust port after blowing up the plasma display; hot air exhausted by the connecting pipeline is filtered by the filter to obtain the clean hot air; the clean hot air is led in the air inlet of the drying furnace to blow up the plasma display to be dried in a circulating way; in the invention, the heat efficiency for drying is high.
Description
Technical field
The present invention relates to a kind of drying oven and drying means that is used for plasma panel.
Background technology
In the process of making plasma panel (PDP), need the slurry in each stage is carried out the drying processing, for example, after electrode, medium, the barrier of plasma flat-plate upper substrate and infrabasal plate are completed for printing, carrying out drying handles, so that remove volatile carrier in the slurry, also be simultaneously on the tentatively fixing substrate of printed figure.As shown in Figure 1, present drying means is by the printing surface of heater 1 heating after heat wind to plasma panel 2 to be dried with cold air, volatile carrier follows heat all to discharge out of the furnace at the exhaust outlet 3 of drying oven in the slurry then, no longer utilizes, and the result causes energy consumption to increase.
Summary of the invention
The present invention is devoted to overcome the above-mentioned defective of prior art just and makes.Technical problem to be solved by this invention is to propose a kind of drying oven of plasma panel and drying means of plasma panel of being used for, and can improve the thermal efficiency of drying oven.
For solving the problems of the technologies described above, the invention provides a kind of drying oven that is used for plasma panel, comprise: heater, the exhaust outlet of being located at the air inlet of heater upstream and being located at the heater downstream, this drying oven also comprises: filter is located at the air inlet place; And connecting pipe, an end of connecting pipe is communicated with exhaust outlet, and the other end is communicated with air inlet by filter.
Preferably, connecting pipe is provided with the gas flow modulation valve.
The present invention also provides a kind of drying means that is used for plasma panel on the other hand, and this method may further comprise the steps: plasma panel to be dried is put into the aforesaid drying oven that is used for plasma panel; Hot-air after the heating of the heater of drying oven is blowed to plasma panel to be dried by air inlet, and hot-air is blown over the volatile carrier taken away behind the plasma panel in the slurry and is discharged from exhaust outlet; Filter through filter by the hot-air after the connecting pipe guiding discharge, to obtain clean hot air; And clean hot air guided to the air inlet of drying oven, blow to plasma panel to be dried with circulation.
The invention has the beneficial effects as follows, because the present invention introduces filter by the hot gas that connecting pipe is discharged the exhaust outlet of the drying oven of plasma panel, and filter by filter, the gas that will contain a large amount of heats is blown in the drying oven from air inlet again, the thermal efficiency when so just having improved kiln dried greatly.
Should be appreciated that above generality is described and the following detailed description is all enumerated and illustrative, purpose is for to the claimed further instruction that the invention provides.
Description of drawings
Accompanying drawing is formed the part of this specification, with helping further understand the present invention.These accompanying drawings illustrate some embodiments of the present invention, and can be used for illustrating principle of the present invention with specification.In the accompanying drawing:
Fig. 1 is the structural representation that is used for the drying oven of plasma panel in the prior art;
Fig. 2 is the structural representation that is used for the drying oven of plasma panel of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.Identical in the accompanying drawings parts are represented with identical label.
With reference to figure 2 drying oven that is used for plasma panel of the present invention is described, it comprises: heater 1, exhaust outlet 3, filter 5 and the connecting pipe 6 being located at the air inlet 4 of heater 1 upstream and being located at heater 1 downstream, wherein, filter 5 is located at air inlet 4 places, one end of connecting pipe 6 is communicated with exhaust outlet 3, and the other end is communicated with air inlet 3 by filter 5.In addition, connecting pipe 6 also is provided with gas flow modulation valve 7.
The present invention also provides a kind of drying means that is used for plasma panel, and this method may further comprise the steps: plasma panel to be dried 2 is put into drying oven of the present invention; Become the hot-air that blows to plasma panel to be dried 2 after heater 1 heating from the cold air drying stove of air inlet, this hot-air is blown over the volatile carrier taken away behind the plasma panel 2 in the slurry and is discharged from exhaust outlet 3; Filter through filter 5 by the hot-air after the connecting pipe 6 guiding discharges, to obtain clean hot air; And clean hot air guided to the air inlet 4 of drying oven, blow to plasma panel to be dried 2 with circulation.And, can also regulate from the flow of the hot-air of exhaust outlet 3 discharges by gas flow modulation valve 7.Arrow among Fig. 2 shows the circulating path of discharge from the hot-air of exhaust outlet 3.
The present invention is because by inserting the hot gas introducing filter 5 that connecting pipe 6 is discharged the exhaust outlet 3 of drying oven, and by filter 5 filtrations, the gas that will contain a large amount of heats is blown in the drying oven from air inlet 3 again, has so just improved the dry heat efficient of drying oven greatly.
Although the present invention is illustrated with reference to accompanying drawing and preferred embodiment, obviously, for a person skilled in the art, under the prerequisite that does not deviate from the spirit and scope of the present invention, can make various changes and variation to the present invention.Various change of the present invention, the content that changes by appending claims and equivalent thereof contain.
