Sectional type float ultra-white glass tin bath top cover

Abstract

The invention provides a sectional type float ultra-white glass molten tin bath top cover. The sectional type float ultra-white glass molten tin bath top cover comprises a bearing mechanism, a first brick body layer, a second brick body layer and a retaining wall, the bearing mechanism comprises a supporting piece, a first hanging piece, a round steel seamless pipe and a second hanging piece. A first embedded bolt part is arranged at the top of the first hanging piece, the first hanging piece and the supporting piece are welded into a whole through the through hole, the first embedded bolt part is fixedly connected with the bearing top, and a second embedded bolt part is arranged on the supporting piece; the round steel seamless pipe is mounted at the bottom of the first hanger; the top ofthe second hanging piece is connected with the round steel seamless pipe, and a protruding part is arranged at the bottom of the second hanging piece. A groove is formed in the second brick body layer, and the protruding part can be inserted into the groove; the bottom of the first brick body layer is sintered and adhered to the top of the second brick body layer; and the retaining wall is firedand bonded at the bottom of the second brick body layer. By means of the structure, temperature and pressure fluctuation can be prevented from influencing the quality of produced glass, and meanwhilethe advantages of simple structure, good bearing effect, long service life and the like are achieved.

Description

technical field [0001] The disclosure generally relates to the technical field of glass manufacturing equipment, and in particular to a segmented float ultra-clear glass tin tank top cover. Background technique [0002] The tin bath is one of the three major thermal equipments for float glass production. The thickness, width and other properties of the float glass are formed in the tin bath, and the top cover of the tin bath plays an important role in the float glass; [0003] This is because during the glass production process, the protective gas, i.e. the mixture of nitrogen and hydrogen, penetrates into the tin tank from the roof brick of the tin tank to ensure that the tin tank is in a positive pressure state, to ensure that the tin liquid is not oxidized, and the glass liquid flows into the tin tank through the flow channel. Tin bath, the glass forms the required different specifications in the process of mechanical external force and its own gravity and tension on the ...

Problems solved by technology

[0003] This is because during the glass production process, the protective gas, i.e. the mixture of nitrogen and hydrogen, penetrates into the tin tank from the roof brick of the tin tank to ensure that the tin tank is in a positive pressure state, to ensure that the tin liquid is not oxidized, and the glass liquid flows into the tin tank through the flow channel. Tin bath, the glass forms the required different specifications in the process of mechanical external force and its own gravity and tension on the entrusted medium tin liquid from the high temperature area to the low temperature area, and the glass changes from liquid to solid during this process. In this process, if the design of the top cover is unreasonable, there will be problems such as many falling objects on the upper surface, difficulty in controlling the tank pressure, and many solder spots.

[0004] In the prior art, the top cover of the tin bath adopts a full-plane structure, that is, the bottom of the top cover of the tin bath corresponds to the high temperature zone, the medium temperature zone, and the low temperature zone of the tin bath, all of which are on the same plane, and there will be a lot of condensation on the top cover during the glass production process When the temperature and pressure fluctuate, the dripping will form defects in the molten glass, which will reduce the quality of the glass

[0005] At the same time, the load-bearing structure of the top cover of the tin bath in the prior art generally fixes several hanging parts on the top of the load-bearing top, the load-bearing effect is not good, the life of the load-bearing parts is short and there are certain safety hazards
