Description

Technical Field

[0001] The utility model relates to the technical field of substrate glass pool furnaces, in particular to a steel structure of a feeding port of a substrate glass pool furnace. Background Art

[0002] The melt overflow method is currently the best process for manufacturing flat panel display glass, and the tank furnace is one of the core components of melting glass. In the field of glass manufacturing, there are many ways to feed the tank furnace, such as blanket feeding, ridge feeding, spiral feeding and intermittent feeding, etc. Each feeding method has its own characteristics and advantages, and can be suitable for different glass production processes. For example, float and photovoltaic glass generally use blanket or ridge feeding machines due to their large production capacity, and overflow substrate or cover glass generally uses spiral feeding machines due to their high control accuracy. In the daily operation of the substrate glass tank furnace, the feeding port is one of the most frequently operated parts, such as replacing the feeding machine, cleaning the feeding port and replacing the feeding hole bricks. Therefore, the process requires that the structure of the feeding port be as simple as possible to facilitate various operations.

[0003] The feed port is the most frequently operated part of the substrate glass tank furnace. Daily operations such as replacing the feeder, cleaning the feed port, and replacing the feed hole bricks will cause varying degrees of fluctuations in the tank furnace process and glass quality from a process point of view. The longer the operation time, the greater the impact, and the greater the yield loss. Therefore, in order to simplify and efficiently operate the feed port, the process requires that the structure of the feed port be as simple as possible, and the design must also comply with the principle of "using a minimal structure to meet reliable functions". For this reason, we provide a steel structure for the feed port of a substrate glass tank furnace. Utility Model Content

[0004] In order to solve the problem in the above background technology that daily operations may cause different degrees of fluctuations in the pool furnace process and glass quality, and the longer the operation time, the greater the impact and the greater the yield loss, the utility model provides a steel structure for the feeding port of the substrate glass pool furnace.

[0007] As a further improvement of the above solution, the columns and L-shaped steel structures are both rectangular tubes made of SUS316 material with a specification of 50*50, which can provide tight support for the feeding port steel structure assembly.

[0008] As a further improvement of the above solution, the upper frame, the lower frame, the frame ear one and the frame ear two are all made of 50*50 angle steel and the angle steel is made of SUS316 material, which can increase the strength of the steel structure assembly of the feeding port.

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] Embodiment 1:

The pool furnace body 1 is an important thermal equipment for melting glass. The glass mixture enters the pool furnace body 1 through the spiral charging machine and the charging port 2 at the lower part of the front wall. Through the gas-electric mixed melting of natural gas and electric melting, a series of silicate physical and chemical reactions are performed to form a high-temperature molten glass liquid, and preliminary clarification and homogenization are performed, which lays the foundation for the high-temperature clarification and homogenization of the platinum channel. The charging port 2 is arranged on both sides of the charging port 2 and connected to the front wall. A fixedly connected column 4, which is an existing supporting steel structure of the front wall, an L-shaped steel structure 5 fixedly connected to the column 4, a top screw 6 arranged on the L-shaped steel structure 5, a nut 7 threadedly connected to the top screw 6, the top screw 6 and the L-shaped steel structure 5 are threadedly connected, the top screw 6 is made of Q235 with a specification of M24*250, a feeding hole brick 8 arranged between the two groups of columns 4 and a feeding port steel structure component 9 arranged outside the feeding hole brick 8, the column 4 and the L-shaped steel structure 5 are both rectangular tubes made of SUS316 material with a specification of 50*50, which can provide tight support for the feeding port steel structure component 9.

[0025] The feeding port steel structure assembly 9 includes an upper frame 901 and a lower frame 902, a bolt 903 for connecting the upper frame 901 and the lower frame 902, a frame ear 1 904 fixedly connected to both sides of the lower portion of the upper frame 901, and a frame ear 2 905 fixedly connected to both sides of the upper portion of the lower frame 902. The upper frame 901, the lower frame 902, the frame ear 1 904 and the frame ear 2 905 are all made of 50*50 angle steel and the angle steel is made of SUS316 material, which can increase the strength of the feeding port steel structure assembly 9, and is fixedly connected to the frame ear 1 904 and connected to the frame ear 2 905 is a movably connected pad 906, an insulating block 907 arranged on the pad 906, and a pressure plate 908 attached to the surface of the insulating block 907. The insulating block 907 is made of a high-temperature resistant alumina insulating plate, and its compressive and flexural strengths are relatively low. Therefore, the pad 906 can provide support for the insulating block 907 to prevent the insulating block 907 from breaking and sliding. The pressure plate 908 is made of SUS304 material. The pressure plate 908 is attached to the surface of the insulating block 907. Its function is to increase the force-bearing area of ​​the insulating block 907 to withstand the pressure of the top screw 6 to prevent it from being crushed.

[0026] The implementation principle of the steel structure of a substrate glass pool furnace feeding port in the embodiment of the present application is as follows: first, the L-shaped steel structure 5 is welded to the column 4, and then the feeding hole brick 8 is placed between the upper frame 901 and the lower frame 902, and the upper frame 901 and the lower frame 902 cover the upper, lower, left and right four surfaces of the feeding hole brick 8. By protecting the feeding hole brick 8, the possibility of cracking and breaking of the brick material due to thermal stress or collision is reduced. If the feeding hole brick 8 cracks during use, it can still be used due to the clamping effect of the feeding port steel structure component 9 on it, and then the feeding hole brick 8 is locked and clamped by adjusting the tightness of the bolt 903, and then the hole of the feeding hole brick 8 is aligned with the feeding port 2 and the feeding port steel structure component 9 is attached to the front wall of the pool furnace body 1, and finally the feeding port steel structure component 9 is fixed by pressing the pressure plate 908 with the top screw 6.
