Description
Technical Field
The utility model relates to the technical field of float glass manufacturing, in particular to a tin bath device of float glass.
Background
In the float glass production process, molten glass at 1150 deg.c is first passed through a runner and a launder before entering a tin bath.
Wherein, the tin bath is the key equipment of float glass production shaping, and the tin bath structure includes entrance end, main part and exit end. The main body part of the tin bath comprises a bath bottom, a breast wall, a top cover, a steel structure, an electric heating, a protective gas inlet pipe, a cooling system and the like. The main body of the molten tin bath is used for containing molten tin so that molten glass flowing into the molten tin bath floats on the molten tin.
In order to prevent tin liquor in the tin bath from being oxidized to make sealing, special structures and facilities are arranged at the inlet end and the outlet end of the tin bath to seal the front and the rear of the tin bath in the process of sealing the tin bath. Because the main body part of the tin bath is provided with an inlet and outlet hole, an operation hole, an observation hole, a temperature measuring hole, a waste discharging hole and the like of the edge roller, the required tin bath edge seal has various internal shapes. Wherein, the tin bath edge seal mainly adopts high temperature resistant heat resistant steel with the thickness of 2 mm and 2520 stainless steel as a shell, and filled with filled heat preservation cotton. The tin bath edge seal of this construction may allow 1050 ℃ tin liquor to be used for ordinary float glass, but is difficult to accommodate in special float glass.
As the temperature of tin liquor in the production of special float glass is 110-150 ℃ higher than that of common tin liquor, edge seals made of 2520 stainless steel materials are ablated and seriously damaged in about half a year. Meanwhile, when 2520 stainless steel is ablated, carbonized and fallen off, the heat preservation cotton inside can also fluctuate along with the groove pressure. Cotton wool of the heat preservation cotton is scattered in the protective gas in the tin bath, so that the dropping of the glass plate surface is increased.
The heat loss caused by the burning loss of the edge seal of the whole tin bath directly causes the unstable temperature of the two sides of the tin bath. When the transverse temperature fluctuation at two sides of the tin bath is too large, the swing operation of the glass plate is unstable, and the thickness difference of the glass plate is influenced to be stable.

Referring to fig. 1 to 6, in an embodiment, a tin bath body 100 includes two sides 110, and a flow chamber 101 is disposed between the two sides 110. Thus, the molten tin during the float glass manufacturing process is located within the flow chamber 101. It will be appreciated that for the flow chamber 101 it comprises at least one inlet end and one outlet end. Molten glass liquid enters the flow chamber 101 through the inlet end and exits the flow chamber 101 through the outlet end.
It should be noted that the tin bath body 100 has a multi-layer structure, and the innermost layer is made of mullite material with high temperature resistance. Specifically, the tin bath body 100 may allow for the inclusion of a protective layer and a thermal barrier layer, with the protective layer comprising a bath bottom steel shell 102 and the thermal barrier layer comprising a bath bottom brick 103 and side wall bricks 104, with the two sides 110 of the tin bath body 100 being built up from the side wall bricks 104. Wherein the bottom steel shell 102 may be allowed to include a bottom surface and two side surfaces, and the bottom bricks 103 are located on the bottom surface and the side wall bricks 104 are located on the side surfaces. It will be appreciated that the flow chamber 101 is located in the region where the channel floor bricks 103 and the sidewall edge bricks 104 are constructed. Wherein, the tank bottom bricks 103 and the side wall edge bricks 104 are made of aluminum silicate refractory materials.
Referring to fig. 1 to 6, in one embodiment, the bottom bricks 103 may be arranged in a stepped manner, so as to effectively reduce solder reflow by the stepped arrangement, thereby improving glass quality.
It is understood that a plurality of baffles 120 are further connected to the tin bath body 100, and the baffles 120 are located at the bottom of the flow chamber 101.

Therefore, the stopper 120 is detachably connected with the tin bath body 100, so that the stopper 120 can be quickly replaced.
Wherein, the baffle 120 is vertically arranged with respect to the flowing direction of the glass. Therefore, the stopper 120 is disposed at the bottom of the flow chamber 101 and perpendicular to the flowing direction of the glass, so as to effectively slow down the flow of the molten tin and reduce the longitudinal temperature difference.
Referring to fig. 1-6, in one embodiment, the top cover 200 is positioned above the flow chamber 101 and the edge seal 300 is positioned between the tin bath body 100 and the breast wall brick layer 111. Specifically, the breast wall brick layer 111 is located on the side 110 of the tin bath body 100, and the breast wall brick layer 111 can be hung above the side 110 through the bracket 112. It will be appreciated that at least one gap is included between the breast wall tile layer 111 and the side edge 110 of the tin bath body 100, i.e., the edge seal 300 is located within the gap. Meanwhile, both sides of the top cover 200 may be allowed to overlap the breast wall brick layers 111 on both sides. The breast wall brick layer 111 is formed by overlapping a plurality of breast wall bricks, and the breast wall bricks are made of high-temperature resistant materials.
The top cover 200 may be allowed to be provided with a plurality of electric heating modules 210, so as to heat the molten tin in the molten tin bath body 100 through the electric heating modules 210, thereby ensuring the stability of the molten tin. In particular, the electric heating module 210 may allow the silicon carbon rods to be used, and the silicon carbon rods are provided with a plurality of groups, and the silicon carbon rods 211 are uniformly provided on the top cover 200. Therefore, the stability of the tin liquid can be effectively ensured by the plurality of group silicon carbide rods 211 which are uniformly arranged.
It should be noted that the edge sealing layer 300 is made of mullite, and a plurality of windows 310 are formed on the edge sealing layer 300. The window 310 may be allowed to act as a vent, thermocouple mounting hole, edge-pull mounting hole, viewing window, flange mounting hole, or small water drum mounting hole, among others. Alternatively, an edge seal may be removably coupled within window 310, and the edge seal may be of mullite, thereby allowing edge sealing of window 310 by the edge seal. When the edge drawing machine is arranged in the window 310, an included angle is formed between the edge drawing machine and the glass ribbon in the tin bath, so that the edge drawing effect on the glass is improved.
In summary, the utility model discloses a tin bath device for float glass, wherein the tin bath body 100 has a multi-layer structure, the innermost layer is made of mullite material with high temperature resistance, and the edge sealing layer 300 is made of mullite material, so that temperature fluctuation of tin liquid caused by the high Wen Sunhui of the edge sealing layer 300 can be effectively avoided.
