Abstract
The utility model relates to novel tin-bath shielding gas cyclic utilization device which comprises a tin bath (1), tin fluid (9) is arranged in the tin bath (1), the side face of the tin bath (1) is provided with a tin bath opening (3), the top end of the tin bath (1) is connected with a gas inlet pipe (2), and the gas inlet pipe (2) is connected with a gas return pipe (2a); and the device is characterized in that the front end of the gas return pipe (2a) is provided with a gas collecting bucket (4).The novel tin-bath shielding gas cyclic utilization device disclosed by the utility model has the advantages that the device is provided with the gas collecting bucket at a shielding gas outlet, and the gas collecting bucket can fully recycle shielding gas blown out of the tin bath, thereby saving resources for enterprises. The device is convenient to install and simple in operation, and can be widely applied to the glass industry.
Description
Technical field
The utility model relates to the shielding gas recycle device in glass production field, particularly a kind of novel molten tin bath shielding gas recycle device that is used to produce sheet glass.
Background technology
Molten tin bath is the molding device of float flat glass production technique, and the glass metal of fusing enters molten tin bath, the sheet glass outlet molten tin bath of moulding, the molten tin bath bottom is the metal tin liquor, forming principle is glass metal to be swum in form sheet glass on the tin liquor, but the easy oxidation of tin liquor, thus influence is used.
Not oxidized for the protection tin liquor, meeting fills the mixed gas of nitrogen and hydrogen in molten tin bath, be referred to as shielding gas, and nitrogen is rare gas element, in order to isolate tin liquor and oxygen; Hydrogen is inflammable gas, can generate water vapor with remaining oxygen, is used for further consuming oxygen.
Because molten tin bath is imported and exported the glass substance turnover is arranged all the time; can't seal with solid matter, so can only use air seal, be exactly constantly to blow out shielding gas in molten tin bath; the outer air of molten tin bath can't be entered in the molten tin bath, thereby protected the tin liquor in the molten tin bath not oxidized.Mostly do not have the shielding gas circulation device in the present stage equipment, even or have the shielding gas cyclic utilization rate also lower, generally have only 10～40%.Through extensively retrieval, still find no relevant technical scheme.
The utility model content
The purpose of this utility model is lower in order to solve present stage shielding gas cyclic utilization rate, shortcomings such as the wasting of resources, and a kind of novel molten tin bath shielding gas recycle device that proposes.
To achieve these goals, the utility model has adopted following technical scheme: a kind of novel molten tin bath shielding gas recycle device, comprise molten tin bath, and tin liquor is housed in molten tin bath, being connected with above the tin liquor needs the refrigerative glass metal.Be provided with the outlet of molten tin bath sheet glass in the side of molten tin bath, cooled glass metal forms sheet glass, leaves molten tin bath from the outlet of molten tin bath sheet glass.Top at molten tin bath connects intake ducting, on intake ducting, connect return-air duct, the segment distance of being separated by on return-air duct is respectively equipped with quick-opening valve and blower fan, it is characterized in that: the front end at return-air duct is provided with the gas collection bucket, and gas collection bucket opening covers the outlet of molten tin bath sheet glass.
On the basis of technique scheme, following further technical scheme can be arranged: the part of described gas collection bucket opening contacts cooperation with the sidewall of molten tin bath.The front end of gas collection bucket opening extends a segment distance outside the sidewall of molten tin bath, and with the upper surface of sheet glass at a distance of a segment distance.
Advantage of the present utility model is: the device that the utility model provides is in the shielding gas exit gas collection bucket to be set, and the gas collection bucket can reclaim the shielding gas that blows out fully from molten tin bath, thereby has saved resource for enterprise.This device is easy for installation, and is simple to operate, can use widely in glass industry.
Description of drawings
Fig. 1 is a basic structure synoptic diagram of the present utility model.
Embodiment
As shown in Figure 1, a kind of novel molten tin bath shielding gas recycle device that the utility model provides comprises molten tin bath 1, and tin liquor 9 is housed in molten tin bath 1, glass metal adrift on the tin liquor.Be provided with molten tin bath sheet glass outlet 3 in the side of molten tin bath 1, the lower-most point of molten tin bath sheet glass outlet 3 is high slightly than the surface of tin liquor 9, and cooled glass metal forms sheet glass 8, leaves molten tin bath from the outlet of molten tin bath sheet glass, is provided with glass carrying roller 7 below sheet glass 8.Top at molten tin bath 1 connects intake ducting 2, on intake ducting 2, connect return-air duct 2a, the segment distance of being separated by on return-air duct 2a is respectively equipped with quick-opening valve 6 and blower fan 5, it is characterized in that: the front end at return-air duct 2a is provided with gas collection bucket 4, and gas collection bucket 4 openings cover molten tin bath sheet glass outlet 3.The part of gas collection bucket 4 openings contacts cooperation with the sidewall of molten tin bath 1.The front end of gas collection bucket 4 openings extends a segment distance outside the sidewall of molten tin bath 1, and forms pneumatic outlet with the upper surface of sheet glass 8 at a distance of a segment distance.With the use of quick-opening valve 6 these devices of control, control the shielding gas cyclic utilization rate less than 100% with the rotating speed of blower fan.
