Description

Technical Field

[0001] The utility model relates to the technical field of glass manufacturing, in particular to an improved liquid crystal glass platinum channel. Background Art

[0002] In the production process of liquid crystal glass, the molten glass liquid enters the platinum channel from the pool furnace, and then enters the muffle furnace, and is formed into liquid crystal glass using the overflow down-draw method. The platinum channel is divided into three parts, the heating and clarification section is one part, the cooling section is one part, and the stirring and feeding section is one part. Each part is an independent whole. In the construction of the production line, the three parts are connected together with flanges. In the production process, after the molten glass liquid comes out of the pool furnace, it first enters the heating and clarification section, then the cooling section, then the stirring and feeding section, and finally flows into the muffle furnace to be formed into liquid crystal glass. Among them, the temperature control of the glass liquid is the most critical part, which directly affects the forming of the glass plate.

[0003] The traditional method is to weld a thermocouple on the surface of the platinum channel to measure the temperature. This temperature can only reflect the surface temperature of the glass liquid, but the internal temperature of the glass liquid cannot be detected, which is not conducive to the forming of the glass plate. This measurement method cannot meet the process requirements. Utility Model Content

[0024] Reference Figure 1-2 The utility model proposes an improved liquid crystal glass platinum channel, comprising: a channel body 1, a first temperature measuring component 2 and a second temperature measuring component 3, wherein:

[0025] A radially arranged inner tube 4 is provided in the channel body 1, and the two ends of the inner tube 4 respectively penetrate the side wall of the channel body 1 to communicate with the outside, and the inner tube 4 and the side wall of the channel body 1 are connected to form a seal; the first temperature measuring element 2 and the second temperature measuring element 3 are respectively inserted into the inner tube 4 from the two ends of the inner tube 4, and the temperature measuring end of the first temperature measuring element 2 or the second temperature measuring element 3 is located at the center of the channel body 1, and a space is reserved between the first temperature measuring element 2 and the second temperature measuring element 3. By comparing the data measured by the first temperature measuring element 2 and the second temperature measuring element 3, the temperature difference between the central temperature and the peripheral temperature of the glass liquid is determined, so as to know the distribution of the temperature field inside the glass liquid.

[0026] In a further embodiment, the insertion depth of the first temperature measuring element 2 and the second temperature measuring element 3 in the inner tube 4 is adjustable. When measuring the temperature, the positions of the two are continuously switched to obtain a more comprehensive distribution of the temperature field inside the glass liquid.

[0027] Reference Figure 3 A first limit baffle 5 is provided in the inner tube 4, and the first limit baffle 5 is located at the center of the channel body 1. When the first temperature measuring component 2 or the second temperature measuring component 3 is installed, when the end of the first temperature measuring component 2 or the second temperature measuring component 3 is against the first limit baffle 5, it means that the temperature measuring end of the first temperature measuring component 2 or the second temperature measuring component 3 has been lowered to the center of the channel body 1.

[0028] Furthermore, a second limit stopper 6 is provided inside the inner tube 4 and on one side of the first limit stopper 5, and the spacing between the second limit stopper 6 and the first limit stopper 5 is greater than N, and N is greater than a preset value of 0, such as N is 1 / 3, 1 / 4, or 1 / 5 of the inner diameter of the channel body 1. When the first temperature measuring element 2 or the second temperature measuring element 3 is installed, the second limit stopper 6 is used to limit the position of the other temperature measuring element. And because N is a preset value, when measuring temperature, when one of the first temperature measuring element 2 or the second temperature measuring element 3 measures the central temperature of the glass liquid, the temperature measuring element is moved to a position with the same insertion depth as the other temperature measuring element, and the temperature difference of the glass liquid at the same circumference can be determined.

[0029] In addition, in this embodiment, both ends of the inner tube 4 are provided with outward-turned flanges, which are attached to the outer wall of the channel body 1 and fixed by welding, so that the inner tube 4 and the channel body 1 form a whole.

[0030] In this embodiment, a plurality of inner tubes 4 are provided and are arranged at intervals along the axial direction of the channel body 1 .

[0031] Furthermore, the material of the inner tube 4 is platinum-rhodium alloy. The first temperature measuring component 2 and the second temperature measuring component 3 are both thermocouples.

[0032] Reference Figure 4-5 In addition, the utility model proposes an improved liquid crystal glass platinum channel, which also includes a lower tank body 7 arranged below the channel body 1 and an upper tank body 8 arranged above the channel body 1 and buckled with the lower tank body 7 to form a covering for the channel body 1. Semicircular grooves 9 are provided at the interface between the upper tank body 8 and the lower tank body 7 and at both ends of the inner tube 4. In the buckled state, the semicircular grooves 9 on the upper tank body 8 and the semicircular grooves 9 on the lower tank body 7 cooperate with each other to form a channel coaxial with the inner tube 4. In order to prevent the first temperature measuring element and the second temperature measuring element from being unable to be installed due to installation errors, the aperture of the channel is larger than the aperture of the inner tube 4.

[0033] Furthermore, the upper tank body 8 and the lower tank body 7 are both built with zirconia bricks.

[0034] As can be seen from the above, the utility model arranges an inner tube 4 in the channel body 1, and arranges the inner tube 4 radially so that it passes through the center of the channel body 1; at the same time, the two ends of the inner tube 4 are respectively passed through the side wall of the channel body 1 to communicate with the outside, and the inner tube 4 is sealed at the junction with the side wall of the channel body 1, so that the inner tube 4 is used to form a detection channel independent of the internal space of the channel body 1 in the inner tube 4 of the channel body 1, and the first temperature measuring component 2 and the second temperature measuring component 3 are respectively inserted into the inner tube 4 from the two ends of the inner tube 4, so that the distribution of the temperature field inside the glass liquid can be known, so as to adjust the heating parameters according to the temperature requirements of the glass plate forming in the subsequent process, ensure that the outlet temperature meets the requirements, and then provide important parameter guarantees for the process.
