Abstract
Description
Technical Field
[0001] This invention relates to glass production equipment, specifically a graphite retaining wall adjustment device for producing ultra-thin glass in a tin bath. Background Technology
[0002] The tin bath is a core piece of equipment in the float glass process and has a significant impact on the quality of float glass. In particular, the control of the molten tin flow largely determines the surface optical quality and micro-ripple properties of the glass. These properties are key performance indicators for evaluating the quality grade of ultra-thin glass (typically ≤1.1mm).
[0003] Graphite baffles within the solder bath are essential for controlling the flow of molten solder. The principle behind this is that graphite and tin are non-wetting and heat-resistant, forming baffles within the molten solder. These baffles effectively block the flow of molten solder, altering the reflux of cold solder and thus allowing for the regional division of the molten solder temperature within the solder bath. Currently, solder baths used for producing ultra-thin glass generally employ graphite baffles with built-in tungsten rods. These baffles are immersed in the molten solder and positioned near the tail end of the bath, and are not adjustable. This means that after the solder bath is put into production, the temperature of the molten solder can only be controlled by heating. However, temperature control within the solder bath is time-delayed because heat exchange between different areas is constantly occurring, making precise control difficult. Therefore, how to adjust the position of the graphite baffles within the solder bath after it has been put into production has become an urgent problem to solve. Summary of the Invention
[0004] In response to the problems raised in the background art, the purpose of this invention is to provide a graphite baffle adjustment device in the tin bath for producing ultra-thin glass. The device uses a drive arm driven by two drive shafts to adjust the position of the graphite baffle in the tin bath, thus solving the problem in the prior art that the position of the graphite baffle in the tin bath cannot be adjusted after production.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A graphite baffle adjustment device for a tin bath used in the production of ultra-thin glass includes a tin bath and a top cover. The tin bath has steel shell walls on both its front and rear sides. The top cover is suspended above the tin bath. Multiple graphite baffles are located inside the tail of the tin bath. Drive shaft A and drive shaft B are located above the tail of the tin bath. Drive shaft A is located to the left of the graphite baffles, and drive shaft B is located to the right of the graphite baffles. Multiple drive arm assemblies A are fixedly connected to drive shaft A, and multiple drive arm assemblies B are fixedly connected to drive shaft B. Each drive arm assembly A and each drive arm assembly B corresponds to one graphite baffle. The drive arm A assembly includes a bushing A fixedly sleeved on the drive shaft A and two drive arms A fixedly connected to the bushing A. The drive arm B assembly includes a bushing B fixedly sleeved on the drive shaft B and two drive arms B fixedly connected to the bushing B. When the drive shaft A rotates, the drive arm B is in a horizontal position, and the lower end of the drive arm A abuts against the lower left side wall of the corresponding graphite retaining wall, driving the graphite retaining wall to move to the right. When the drive shaft B rotates, the drive arm A is in a horizontal position, and the lower end of the drive arm B abuts against the lower right side wall of the corresponding graphite retaining wall, driving the graphite retaining wall to move to the left.
[0007] The graphite retaining wall has a tungsten rod fixed inside, and tungsten plates are fixed on both sides of the lower part of the graphite retaining wall. The tungsten plates and tungsten rods are fixed together.
[0008] The drive shaft A has two ends that pass through the front and rear steel shell walls of the tin bath, and a motor A is installed on one side of the steel shell wall. The main shaft of the motor A is fixedly connected to the drive shaft A. The drive shaft B has two ends that pass through the front and rear steel shell walls of the tin bath, and a motor B is installed on one side of the steel shell wall. The main shaft of the motor B is fixedly connected to the drive shaft B.
[0009] Both drive shafts A and B are located between the tin bath and the top cover, and both ends of drive shafts A and B are sealed to the corresponding steel shell walls by an air-sealing mechanism.
[0010] The drive arm A has a top block A on the lower right side, which abuts against the tungsten plate on the left side wall of the graphite retaining wall; the drive arm B has a top block B on the lower left side, which abuts against the tungsten plate on the right side wall of the graphite retaining wall.
[0011] The beneficial effects of this invention are as follows: The two drive arms designed in this invention can drive the graphite baffles in the tin bath to move left and right in the tin bath respectively. By moving the graphite baffles, the temperature regulation of the molten tin in the tin bath can be changed, providing a new idea and solution for adjusting the temperature regulation of the molten tin in the tin bath online.

[0019] like Figure 1-3 As shown, this invention proposes a graphite baffle adjustment device for producing ultra-thin glass in a tin bath, comprising a tin bath 1 and a top cover 2. The tin bath 1 has steel shell walls 3 on both its front and rear sides. The top cover 2 is suspended above the tin bath 1. Multiple graphite baffles 4 are located at the tail end of the tin bath 1, below the surface of the molten tin 11 and placed on the bottom brick of the tin bath 1. A drive shaft A5 and a drive shaft B6 are located above the tail end of the tin bath 1. Drive shaft A5 is located to the left of the graphite baffle 4, and drive shaft B6 is located to the right of the graphite baffle 4. Multiple drive arm assemblies A are fixedly connected to drive shaft A5, and multiple drive arm assemblies B are fixedly connected to drive shaft B6. One drive arm assembly A... Each drive arm assembly B corresponds to a graphite retaining wall 4. The drive arm assembly A includes a bushing A fixedly sleeved on the drive shaft A5 and two drive arms A fixedly connected to the bushing A. The drive arm assembly B includes a bushing B fixedly sleeved on the drive shaft B6 and two drive arms B fixedly connected to the bushing B. When the drive shaft A5 rotates, the drive arm B is in a horizontal position, and the lower end of the drive arm A abuts against the lower left side wall of the corresponding graphite retaining wall 4, driving the graphite retaining wall 4 to move to the right. When the drive shaft B6 rotates, the drive arm A is in a horizontal position, and the lower end of the drive arm B abuts against the lower right side wall of the corresponding graphite retaining wall 4, driving the graphite retaining wall 4 to move to the left.
