Description

A kind of baffle for preventing overflow launder from deteriorating

[technical field]

The utility model belongs to glass substrate manufacturing field, and in particular to a kind of baffle for preventing overflow launder from deteriorating.

[background technique]

Glass substrate of the thickness between 0.3mm~1.0mm is mainly used for flat panel display, is in flat-panel monitor One of critical component.FPD is on influencing its optics, mechanical strength, thermal stability and surface smoothness requirement in glass substrate It is high, therefore be even more important in the production process of glass substrate to quality and production stability control.

Overflow downdraw technique can shape the glass sheet substrate of high quality, which is for producing in flat-panel monitor The preferred technique of glass substrate, the glass substrate produced by technique table compared with the glass substrate produced by other methods Face has more excellent flatness and smoothness.Referring to Fig. 1, traditional molding machine overflow downdraw is utilized one kind and is commonly referred to as The molding machine Refractory blocks of the special shape of overflow brick, in traditional forming device overflow brick 7, the glass metal of flowing, which flows into, to overflow Slot 2 out are flowed downward due to the power of gravity and the withdrawing roll for pulling glass metal along diagram direction, and in the region close to root 6 In it is thinning, to produce required glass plate 5.Wherein the effect of L pipe 1 is will to dissolve the glass metal clarified with certain gesture 7 entrance of overflow brick can be flowed into, forms the glass plate of uniform thickness by overflow brick 7.

Overflow brick under high temperature environment after a period of use because under the glass metal weight of itself and carrying, with The lengthening of time, overflow brick ontology can deform, and at deformed overflow brick near-side inlet port and L pipe can generate gap, cause Part flows into gap location when glass metal flows into overflow brick entrance from L pipe, influences glass metal entirety overflow situation, when gap is big, makes It is deteriorated at glass metal overflow situation, so that molding rear glass plate quality decline.

[utility model content]

The shortcomings that the purpose of the utility model is to overcome the above-mentioned prior arts provides a kind of gear for preventing overflow launder from deteriorating Plate.The utility model manages in L and increases baffle between overflow brick, is fixed on the junction of L pipe and overflow brick, avoids high temperature glass Glass liquid is directly contacted with junction, generates gap.

In order to achieve the above objectives, the utility model is achieved using following technical scheme:

A kind of baffle for preventing overflow launder from deteriorating, including two side plates and a bottom plate, the bottom end of two side plates respectively and Longitudinal both ends of bottom plate are fixedly connected, the length of bottom plate and overflow launder it is of same size；The baffle is put into L pipe and overflow launder When, the lower surface fitting of the upper surface and bottom plate of L pipe and overflow launder junction bottom surface, L manages interior with overflow launder junction two sides Wall is bonded with the outer surface of two side plates respectively.

Further improvement of the utility model is:

Preferably, the bottom end of two side plates and the junction of bottom plate are provided with the first chamfering；The bottom surface of overflow launder and inner wall Junction is provided with the second chamfering, and the first chamfering is identical with the second chamfer dimesion.

Preferably, two side plates and a bottom plate are integrally formed.

Preferably, baffle selects platinum material.

Preferably, bottom plate laterally has 5mm-40mm to be bonded with the bottom surface of overflow launder.

Preferably, the height of side plate and the height of overflow launder are identical.

Preferably, which is characterized in that connection is welded and fixed in the underrun of bottom plate and L pipe.

Compared with prior art, the utility model has the following beneficial effects:

The utility model discloses a kind of baffles for preventing overflow launder from deteriorating, and the baffle is by two side plates and a bottom plate Composition, when the baffle is in molding machine L pipe and overflow launder, the outer surface of baffle and the fitting of overflow launder inner wall；Work as glass metal When flowing into overflow launder from L pipe, flowed into inside overflow launder by the baffle, prevent glass metal directly with overflow launder and L pipe Contact position contact, causes to generate gap between overflow brick glass metal inlet and L pipe；Ensure that the service life of molding machine with Quality in glass plate process of setting；The outer surface of baffle and the fitting of overflow launder inner wall, can guarantee melt flow fluency； The utility model is used in production find, use in two years, there is a phenomenon where glass metals to omit to gap, overflow brick glass There is no deteriorations for the overflow situation of glass liquid inlet.

Further, the junction of side plate and bottom plate carries out chamfered, the chamfering of chamfering and overflow groove sidewall and bottom surface It is identical, guarantee that baffle can be fitted closely with overflow launder inner wall, guarantee the fluency of melt flow, while anti-baffle plate and overflowing It is had the gap between chute, glass metal, which flows into, corrodes overflow brick.

Further, side plate and bottom plate are integrally formed, and guarantee that baffle is durable, extend the service life of baffle.

Further, baffle preferentially selects platinum material, and chemical property and the high-melting-point of platinum stable material quality can guarantee When glass flows through baffle, baffle will not be eroded.

Further, bottom plate is laterally inserted to 5mm-40mm in overflow launder, and the protection that guarantee baffle is capable of larger area is overflow Chute.

Further, the height of side plate and the height of overflow launder are identical, when glass flow quantity is larger, side plate can from overflow Chute top prevents glass metal from entering the contact position of overflow launder and L pipe.

Further, bottom plate and L pipe are fixedly connected by welding, and it is firm to guarantee that baffle is connected with L pipe.
