Description
Technical field
The present invention relates to the manufacturing technology field of float glass, more particularly to a kind of electronical display glass platinum channel flashboard
Sealing device.
Background technology
With the development of electronical display glass, manufacture large format ultra-thin glass with floating process becomes only way.
In conventional float technique, for raw material after melting furnaces fusing, glass metal flows into tin groove forming from the flow liquid road of rectangular section；In flow liquid road
Flashboard is equipped with, for controlling glass flow quantity, to control plate glass thickness.On flow liquid road, to ensure the activity of flashboard
Property, leave gap between flashboard and flow liquid road head cover.In flow liquid road, glass metal is non-full slot status, can use head cover upper table
Face sealing means, such as Patent No. 201510476395.7, the patent Shen that patent name is a kind of flow liquid road flashboard sealing device
Please.But when in flow liquid road, when glass metal is tankful state, which cannot meet requirement, glass metal or can be from lock
Overflow in gap between plate and transition passage head cover.
To improve product quality, before glass metal flows into tin groove forming process, glass liquid stirring process is specially additionally arranged,
With the uniformity coefficient for reducing the number of bubbles in glass metal, improving glass metal.
In agitating procedure, agitating device by agitator, rabble, agitator cover board, inlet, liquid outlet, unload liquid mouth, electricity
Heater etc. forms, and agitator, rabble dispose vertically, rabble platinum material, slow rotation（1-15rpm）, it is resistance to prevent
Bubble penetrates into glass metal, slows down erosion of the glass metal to agitator wall in fiery material, and apply is heat-resisting on agitator inner wall
Platinum layer, is known as platinum channel.
Platinum channel liquid outlet is circular cross-section, and molten tin bath inlet is rectangular section, must add section gradually therebetween
The transition passage of change, circulates for glass metal.When manufacturing large format ultra-thin glass with floating process, lock is set on transition passage
Plate, for controlling glass flow quantity.Due to platinum channel structure and due to pressure, platinum channel liquid outlet and transition passage or it is
Tankful state, glass metal or gap that can be between flashboard and transition passage head cover are overflowed, and have reused upper surface sealing means
It is not suitable for.
The content of the invention
The purpose of the present invention is to solve in the prior art the shortcomings that, and propose a kind of electronical display glass platinum lead to
The sealing device of road flashboard.
To achieve these goals, present invention employs following technical solution：
A kind of sealing device of electronical display glass platinum channel flashboard, including flow liquid passage, are equipped with the upside of flow liquid passage
Head cover, is equipped with slot on head cover, and flashboard is equipped with slot, it is characterised in that：It is equipped with the upside of the slot of flow liquid channel side
Riser, is equipped with gap between riser and flashboard, one section is equipped with the upside of riser to the inclined clapboard in flashboard side, in gap
Equipped with the graphite cake for sealing, lozenges is equipped with the upside of the graphite cake of riser side, downside is equipped with chamfered edge, lozenges and wedge
Shape plate corresponding matching.
Based on the above technical solutions, there can be technical solution further below：
In the inner wall mating connection passage platinum layer of the flow liquid passage.
Flashboard platinum layer is equipped with the side wall that the flashboard contacts side with glass metal.
Riser platinum layer is equipped with the side wall that the riser contacts side with glass metal.
Extension plate is additionally provided with the upside of the clapboard.
Horizontal through hole is equipped with the upside of the graphite cake.
The advantage of the invention is that：The present apparatus is simple in structure, between in the upside of flow liquid channel side slot, setting riser is raised
The position of gap opening, sets the graphite cake for being capable of activity, with the increase of glass liquid measure in passage, graphite cake is by glass in gap
Glass liquid floats, and seal clearance, effectively prevents the spilling of glass metal, under glass metal thrust, graphite cake opposite side
Compress sealing naturally between head cover, improve air-tightness between flashboard slot and flashboard.

Fig. 1 is the basic structure schematic diagram of the present invention；
Fig. 2 is view of the present invention when glass metal is non-tankful；
Fig. 3 is view of the present invention when glass metal is tankful.
Embodiment
In order to which the present invention is more clearly understood, the present apparatus is described in detail below in conjunction with attached drawing, tool described herein
Body embodiment only to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, Figure 2 and Figure 3, the sealing dress of a kind of electronical display glass platinum channel flashboard provided by the invention
Put, including flow liquid passage 1, head cover 2 is equipped with the upside of flow liquid passage 1, slot 3 is equipped with head cover 2, is equipped with slot 3
Flashboard 4, in the upside snapping buckle 11 of flashboard 4, connects elevating lever 12, the downside insertion flow liquid passage 1 of flashboard 4 on buckle 11
In with passage 13 corresponding current limliting of glass metal coordinate, be correspondingly arranged molten tin bath 10 in the rear side of flow liquid passage 1, limited by flashboard 4
Glass metal 13 after stream is flowed into molten tin bath 10.In the inner wall mating connection passage platinum layer 7 of flow liquid passage 1, in flashboard 4 and glass
The side wall that glass liquid 13 contacts side is equipped with flashboard platinum layer 8.
Be equipped with riser 5 in the upside of slot 3 of 1 side of flow liquid passage, riser 5 is arranged in parallel with flashboard 4, in riser 5 and
Gap 6 is equipped between flashboard 4, one section is equipped with to the inclined clapboard 5a in 4 side of flashboard in the upside of riser 5, in the riser 5 and glass
The side wall of 13 contact side of glass liquid is equipped with riser platinum layer 5c, and extension plate 5b, extension plate 5b are additionally provided with the upside of clapboard 5a
Also it is arranged in parallel with flashboard 4.The graphite cake 9 for sealing, the downside insertion flow liquid passage 1 of graphite cake 9 are equipped with gap 6
In, when there is no glass metal 13 in flow liquid passage 1, the downside of graphite cake 9 touches flow liquid passage 1 under gravity
Lower wall, the upside of graphite cake 9 of 5 side of riser is equipped with lozenges 9a, downside is equipped with chamfered edge 9b, lozenges 9a and chamfered edge 9b divide
The corner of graphite cake 9 is not arranged on, due to the presence of chamfered edge 9b so that deposited between the lower wall of graphite cake 9 and flow liquid passage 1
In gap, which facilitates glass metal to flow out and float graphite cake 9, after graphite cake 9 floats, 5a pairs of lozenges 9a and clapboard
Cooperation should be sealed, glass metal 13 is effectively prevented and overflows.
The gap of this programme dynamic sealing head cover, under 13 thrust of glass metal the head cover 2 of graphite cake 9 and 10 side of molten tin bath from
Sealing is so compressed, after glass metal 13 gradually increases, graphite cake 9 is gradually floated, and is fully sealed until gap 6, due to stone
With refractory material high temperature adhesion will not occur for ink stick 9, when flashboard 4 is up and down, only need to overcome graphite floating block buoyancy, glass
The extruding of glass liquid 13 can make graphite cake abut flashboard, and graphite cake is consolidated.To increase graphite cake buoyancy, sealing effect is improved,
The upside of graphite cake 9 more than glass metal plane is equipped with horizontal through hole.
