Description

Material storage equipment for storing slurry

technical field

The invention relates to the field of displays, in particular to a material storage device for containing and storing slurry in the display manufacturing process.

Background technique

A large amount of slurry is used in the production process of a plasma display panel (PDP for short). Fig. 1 shows a storage tank 1 for storing slurry commonly used in the prior art. As shown in FIG. 1 , the storage tank 1 has an arc-shaped top cover 2 and slurry 3 is stored in the storage tank 1 . The slurry 3 contains a volatile organic carrier, and especially during the vacuum defoaming operation of the slurry 3, part of the organic carrier in the slurry 3 is extremely volatile due to negative pressure, when the organic carrier volatilizes to the storage tank 1, these organic carriers will accumulate on the top cover 2 of the storage tank 1, and with the increase of the organic carrier on the top cover 2, they will gather and produce condensation. When the droplet of the organic carrier is large enough, The organic vehicle droplets will drip into the slurry, affecting the quality of the slurry and ultimately resulting in poor product quality.

In addition, with the continuous increase of PDP size and the realization of multi-faceted printing, the amount of paste used will increase accordingly. Therefore, if the storage tank of the prior art as described above is used to store the slurry, a large amount of manpower and material resources are required during the slurry handling, inspection and vacuum degassing, which increases the labor cost and affects the cleaning of the slurry. The degree of influence is great, and it is easy to cause the yield rate to drop.

Detailed ways

The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to only the embodiments presented herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the same reference numerals denote the same elements.

Figure 2 shows a storage device for storing slurry according to the invention. As shown in FIG. 2 , the storage device 10 includes a body 20 with an open top and a top cover 30 mounted on the top of the body 20 . The bottom of the body 20 is provided with a flange 22, which can be opened as a slurry input and output port so that the body 20 communicates with a delivery pipe (not shown) for transporting the slurry, whereby the slurry 40 enters the slurry. And stored in the main body 20. A flange 32 is provided on the top cover 30, and the flange 32 can be opened as a vacuum port so that the storage device body 20 communicates with the vacuum system, thereby performing vacuum degassing operation on the slurry 40 in the body 20 ( as described below).

In the embodiment of the present invention, as shown in FIG. 1 , the top cover 30 includes an inner surface 300 inclined relative to the horizontal plane, that is, the inner surface 300 may be inclined, and may preferably be herringbone as shown in FIG. 1 Roof-like. Moreover, a liquid receiving groove 34 is further provided on a portion of the inner surface 300 of the top cover 30 adjacent to the top end of the main body 20 . In this way, especially during the vacuum defoaming operation of the slurry 40, when the volatilized organic carrier reaches the inner surface 300 of the top cover 30, it is easy to slide down to the liquid receiving tank 34 along the inclined slope, and will not be like the existing one. As in the technology, it gathers on the inner surface of the relatively flat top cover and falls into the slurry due to gravity, affecting the quality of the slurry.

In order to further promote the volatilized organic carrier to slide smoothly into the liquid receiving tank 34, a flow diversion groove 36 extending from the top of the top cover 30 to the liquid receiving tank 34 is also provided on the inner surface 300 of the top cover 30, so that the organic carrier Advantageously, it slides down into the liquid receiving groove 34 along the guide groove 36 . Preferably, these guide grooves 36 are capillary-shaped.

In this embodiment, the top cover 30 is detachably installed on the top of the main body 20 , and the liquid receiving tank 34 is detachably disposed on the inner surface 300 of the top cover 30 . When the organic carrier in the liquid receiving tank 34 is excessive, the top cover 30 can be opened, the liquid receiving tank 34 is taken out and the organic carrier therein is emptied, and then the liquid receiving tank 34 is installed.

In principle, the greater the angle between the inner surface 300 of the top cover 30 and the horizontal plane, the better the effect, but this will increase the height of the top cover and increase the space occupied by the storage tank. Therefore, preferably, the inner surface of the top cover 30 300 at an angle of 45° to the horizontal.
