Description
Technical Field
The utility model relates to a float glass production field, concretely relates to float glass runner prevents convection current device.
Background
The float glass production process is the mainstream glass production process at present, and mainly comprises the steps of melting glass raw materials such as quartz sand and the like into glass liquid at high temperature in a kiln, introducing the glass liquid into a high-temperature tin liquid tank, paving the glass liquid on the surface of the tin liquid under the action of surface tension, gravity and the like due to the fact that the density of the glass liquid is lower than that of the tin liquid, controlling the thickness of the glass liquid in the tin liquid tank by matching with an edge roller and the like, leading the glass into an annealing kiln to form a glass ribbon, and forming a glass plate after cooling and cutting. In the process of introducing molten glass into a molten tin bath from a kiln, because the kiln and the molten tin bath are relatively independent devices, a flow channel is usually arranged between the kiln and the molten tin bath to guide the molten glass, and a gate structure is arranged at the flow channel to facilitate the control of the flow of the molten glass. The flow channel is exposed outside the kiln and the molten tin bath and is in more contact with the external environment, particularly the flow channel is small relative to the kiln and the molten tin bath, transverse air convection can be generated at the flow channel, the temperature of molten glass passing through the flow channel and molten tin adjacent to the flow channel can be changed, and the molten tin is oxidized, cooled and the like due to oxygen in the air, so that the quality of the molten tin and the molten glass can be greatly influenced.
SUMMERY OF THE UTILITY MODEL
The utility model discloses it prevents convection current device to anticipate to provide float glass runner to there is the air convection to influence the problem of glass liquid quality between kiln and molten tin bath in solving current float glass production process.
In order to achieve the above purpose, the basic technical scheme of the utility model is as follows: float glass runner prevents convection current device, including the door frame of two rectangles that set up side by side, be connected with the roof of rectangle between the top of two door frames, the bottom of every door frame all is equipped with two at least pillars, all rotates in every door frame to be connected with the door leaf of opening, and the door leaf includes left side door and right side door, and the bottom of right side door rotates and is connected with the locking plate, is fixed with the hasp on the base of door frame.
The principle and the advantages of the scheme are as follows: during practical application, two door frames are respectively located the both sides of glass kiln and molten tin bath junction runner, and the door leaf that runs from opposite directions of installation in the door frame is closed the back and is sheltered from the runner both sides, and the roof shelters from the runner top, covers the runner like this for the runner is located the space that roof, door leaf enclose and closes, and the runner both sides do not communicate after the door leaf is closed, does not have the air of convection current, can not cause the influence to the molten glass or molten tin in the runner. The pillar supports the door frame to a certain height, and the pillar with different heights can be selected according to the actual conditions of the workshop, so that the door frame is more suitable for the actual use conditions of the workshop. The door leaf that the adoption was run from opposite directions can be opened completely, and the workman of being convenient for gets into wherein and operates, and the in-process that opens and shuts is not direct open, can the certain degree cushion air flow. The locking plate and the lock catch are adopted to lock the door leaf, the structure is simple and practical, and the operation is simple and convenient.
Furthermore, two groups of heat dissipation holes are arranged on the top plate and are symmetrically distributed by using a central line between the two door frames. As the preferred runner top opening setting, the high temperature of glass liquid and tin liquid can cause the hot gas flow to strike the roof, can evenly derive the heat dispersion through the louvre, reduces the pressure that receives in the long-term use of roof, adopts symmetric distribution to make the hot gas flow evenly derive from both sides, further guarantees that the roof can not take place ascending arch and warp.
Furthermore, a flow guide cover positioned above the heat dissipation holes is fixed on the top plate, and the flow guide cover is provided with an opening facing to the center line of the top plate. The air flow is guided by the air guide sleeve preferably, the air convection at the two sides of the flow channel can be avoided by arranging the opening of the air guide sleeve, the air convection can enter the anti-convection device from the air guide sleeve, and the hot air flow can be guided to flow towards the same direction, so that the workshop can be guided to dissipate heat conveniently.
Furthermore, the upper end of the top plate is provided with a strip-shaped reinforcing rib positioned between the two groups of heat dissipation holes, and the reinforcing rib is arranged in parallel with the central line of the top plate. The strengthening rib carries out the structure reinforcement to the roof as preferred setting, can improve the structural strength of roof, avoids the roof to produce the deformation that ascending bending deformation brought for door frame and door leaf.
Furthermore, the cross-section of the reinforcing rib is triangular, and one side wall of the reinforcing rib is attached to the top surface of the top plate. The reinforcing rib preferably adopting the structure has better structure reinforcing effect on the top plate, and the stress critical value of the top plate which is bent upwards and deformed is improved through the stable support of the triangle; the triangle can further guide the hot air flow guided by the air guide covers on the two sides to the upper space, thereby avoiding the hot air flow emitted by the two groups of heat dissipation holes from convection on the top plate, and simultaneously shielding the opening of the air guide cover, and avoiding the opposite air convection from blowing into the air guide cover.
Furthermore, the reinforcing ribs are of hollow structures, and cooling water which flows circularly is filled in the reinforcing ribs. Preferably, the top plate can be cooled by filling the cooling water which flows circularly, the deformation or burning of the top plate caused by high-temperature baking of the molten glass in the flow channel for a long time is avoided, the hot air flow blown out of the flow guide cover can be subjected to heat exchange, and part of heat is recycled by water while the heat emission of a workshop is reduced.
Further, the left side door and the right side door are both hollow structures. Make left side door and right side door have better thermal-insulated effect like this as preferred, be difficult for scalding operating personnel in the operation process, and the quality is lighter, and it is more convenient to operate.
Furthermore, through holes are formed in the side walls, facing the flow channel, of the left side door and the right side door. The through holes are preferably arranged on the inner side of the door leaf, can be used for hanging tools, and are multifunctional and more practical.
