Description

TECHNICAL FIELD

[0001] The utility model relates to the float glass production field, in particular to a kind of float glass flow channel cover plate brick protection fixture. BACKGROUND

[0002] The process of float glass production forming is completed in tin bath into which protective gas is passed, and the forming equipment of float glass is called tin bath because it is tank-shaped container filled with molten tin liquid, and it is the core of glass forming process and is regarded as one of the three major thermal equipment in float glass production process.

[0003] After being melted, clarified and cooled to about 1150-1100℃, the glass liquid is continuously flowed into tin bath through the channel connected with tin bath and the flow channel deeply into tin bath and floated on the surface of tin liquid with relatively large specific density, and the glass plate with different thickness is formed under the joint action of gravity, surface tension, the force of edge puller and the main driving force.

[0004] The channel connected between the cooling part of melting furnace and tin bath is commonly called flow channel, and the flow channel refers to the channel through which hot glass liquid flows from melting furnace into tin liquid in tin bath, and it is the most important component of float glass production process, and the sealing condition of flow channel has great influence on glass production quality.

[0005] The cover plate brick used for sealing the flow channel is made of sillimanite, and due to high temperature of flow channel, the cover plate brick will be broken with the increase of use time and possible external force, and the broken cover plate brick has the risk of falling into flow channel, which has great hidden danger to production, so the cover plate brick must be clamped by clamp made of stainless steel to avoid falling into flow channel due to breakage of cover plate brick. Figure 1 As shown in the side view of existing cover plate turning clamp 1' shown in the drawing, the clamping inner cavity is adapted to the structure of cover plate brick 2, and the total length of cover plate brick 2 used is about 2000mm, and the total length of clamp used satisfies the requirement of overlength of 2000mm, and due to the relatively long length of clamp, the steel clamp will be twisted and deformed under high temperature environment of flow channel with the continuous extension of use time, and different forces will be generated on each part of cover plate brick, which easily leads to breakage of cover plate brick, and the debris falls into flow channel, which affects the quality of glass plate, and the gap between bricks affects the sealing property of flow channel.
