Abstract
The invention provides a sealing structure for reinforcing outlet sealing of a tin bath. The sealing structure comprises a steel pipe, a check cloth and an outlet partition wall brick which are arranged in a slag box, wherein the steel pipe is used for conveying nitrogen with pressure into a gap between the check cloth and the outlet partition wall brick to form a gas curtain which is used for blocking external air from entering the tail end of the tin bath to achieve an effect of sealing the outlet of the tin bath. The sealing structure for reinforcing the outlet sealing of the tin bath, provided by the invention, is simple and reliable in structure, greatly improves the problem of the outlet sealing of the tin bath, and is very low in design cost and very high in feasibility.
Description
Technical field
The present invention relates to floatation glass production line, for strengthening the sealing of tin bath outlet, belonging to process of glass field.
Background technology
Owing to carry tin liquor in molten tin bath; the tin liquor of high temperature is easily oxidized; its stannic oxide produced directly affects the quality of glass; also unnecessary tin consumption is caused on the other hand; so we pass into nitrogen hydrogen shielding gas at molten tin bath; to ensure that molten tin bath is in pressure-fired condition for a long time, extraneous air can be avoided to enter, also will ensure the stopping property of molten tin bath as far as possible.But molten tin bath end is the outlet of glass ribbon, cannot seal completely.We took check apron sealing structure tin bath outlet originally, but due to the lifting structure of check apron, check apron cannot be allowed to be close to tin bath outlet place, extraneous air enters molten tin bath, and tin bath pressure drop is low, the tin generation oxidizing reaction of the oxygen in air and molten tin bath afterbody, the easy tin sticky of glass, affects glass quality.
Summary of the invention
The present invention is intended to propose a kind of new structure, to improve the sealing of tin bath outlet.
In order to reach above-mentioned purpose, provide a kind of sealed structure strengthening tin bath outlet sealing, comprise the steel pipe being located at slag case, shelves curtain, and outlet partition block, nitrogen with pressure being delivered to the space between described check apron and described outlet partition block by described steel pipe, forming gas curtain for stopping that extraneous air enters molten tin bath end.
In some embodiments, described steel pipe is rectangular steel pipe.
In some embodiments, the bottom of described steel pipe has elongated slot.
In some embodiments, the length of described elongated slot is determined according to molten tin bath inner width.
In some embodiments, also comprise variable valve, to control nitrogen flow and switch.
In some embodiments, described outlet partition block opens a chamfering in the direction that described steel pipe is supplied gas, play the guiding role.
In some embodiments, the both sides of described check apron are provided with sidepiece banding.
In some embodiments, described sidepiece banding is concave structure.
According to the sealed structure of reinforcement tin bath outlet sealing of the present invention, its structure is simple, and reliably, substantially improve the problem of tin bath outlet sealing, its design cost is very cheap, and feasibility is very high.
Below in conjunction with accompanying drawing, the description of purport of the present invention is described by example, to know other aspects of the present invention and advantage.
Accompanying drawing explanation
By reference to the accompanying drawings, by detailed description hereafter, above-mentioned and other feature and advantage of the present invention more clearly can be understood, wherein:
Fig. 1 is the structural representation of sealed structure between tin bath outlet and slag case according to the embodiment of the present invention;
Fig. 2 (a)-(c) is tin bath outlet, check apron and sidepiece banding scheme of installation.
Embodiment
See the accompanying drawing of the specific embodiment of the invention, hereafter in more detail the present invention will be described.But the present invention can realize in many different forms, and should not be construed as by the restriction in the embodiment of this proposition.On the contrary, it is abundant and complete open in order to reach for proposing these embodiments, and makes those skilled in the art understand scope of the present invention completely.
Description describes a kind of sealed structure strengthening tin bath outlet sealing according to the embodiment of the present invention in detail.
As shown in the figure, the steel pipe being located at slag case is comprised, shelves curtain according to the sealed structure that the reinforcement tin bath outlet of the embodiment of the present invention seals, and outlet partition block, nitrogen is delivered to the space between described check apron and described outlet partition block by described steel pipe, stops that extraneous air enters molten tin bath end.
Described sealed structure comprises rectangular steel pipe 1, variable valve 2, first check apron 3, outlet partition block 4, and sidepiece banding 5, slag case 6 form, and refer to Fig. 1 and Fig. 2 (a)-(c).
Pass into nitrogen at first rectangular steel pipe 1 of slag case 6, control nitrogen flow and switch with variable valve 2.The wide elongated slot of a 2mm is opened in rectangular steel pipe 1 bottom, and elongated slot length is determined according to molten tin bath inner width.Nitrogen can be delivered to like this in the space between first check apron 3 and outlet partition block 4, play the effect by nitrogen sealing gland, stop that extraneous air enters molten tin bath end.Outlet partition block 4 opens a chamfering in the direction that rectangular steel pipe 1 is supplied gas, play the guiding role.See Fig. 1
Be originally flat construction at the sidepiece banding of soft check apron 3 both sides, now adopt concave structure.This concave structure can slow down the speed and amount that air enters greatly, avoids the leakage (see Fig. 2) that vertical masonry joint causes.Sealed structure of the present invention is used for tin bath in floating glass production line outlet and slag case.
According to the sealed structure of reinforcement tin bath outlet sealing of the present invention, its structure is simple, and reliably, substantially improve the problem of tin bath outlet sealing, its design cost is very cheap, and feasibility is very high.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.All technician in the art, all should by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
