Description

Technical Field

[0001] The utility model relates to the technical field of glass production equipment, in particular to an anti-drip heater used in substrate glass production. Background Art

[0002] Due to the characteristics of the process, the key brick tip of the overflow liquid crystal glass substrate molding is prone to poor process such as material accumulation and large and small materials, which eventually leads to crystallization at the brick tip. Crystallization at the brick tip will greatly affect the overflow liquid crystal glass substrate molding process. In order to avoid the influence of brick tip crystallization on the overflow liquid crystal glass substrate molding process, the brick tip crystallization needs to be heated and melted, but the molten glass liquid on the front or back side of the brick tip is easy to drip downward from the front or back side of the brick tip. Long-term dripping is likely to cause poor quality of the molded glass substrate, or damage to the core equipment below due to hanging of materials. Utility Model Content

[0020] The heating plate includes a plate body 1 and a heating tube 2. A receiving groove is provided on the top of the plate body 1. A partition plate 11 arranged along a second horizontal direction is provided in the receiving groove. The partition plate 11 divides the receiving groove into a first groove body 12 and a second groove body 13 arranged along a first horizontal direction perpendicular to the second horizontal direction.

[0022] Since the two edge-pulling shafts 3 are located below the heater and are respectively located on both sides of the center of the heater in the second horizontal direction, the arrangement of the disk body 1 and the first trough body 12 in the utility model increases the length of the disk body 1 in the first horizontal direction compared to the prior art, and the heater can be moved to a position where the heating tube 2 maintains a distance of 5-10mm from the crystallization position of the brick tip 4 in the first horizontal direction, so that the first trough body 12 is located below the crystallization position of the brick tip 4; the crystallization of the brick tip 4 is heated and melted by the heating tube 2, and the molten glass drips into the first trough body 12 and is discharged along the discharge port 14, which can prevent the molten glass from dripping onto the edge-pulling shaft 3 and the roller of the edge-pulling shaft 3, thereby avoiding problems such as poor quality of the formed glass substrate and damage to the edge-pulling shaft 3 caused by long-term dripping.

[0023] In this embodiment, the height of the partition 11 is lower than the height of the heating tube 2 installed in the second tank body 13 to avoid affecting the heating efficiency of the heating tube 2 .

[0024] In a further embodiment, the top surface of the partition 11 is an inclined surface that slopes upward from the first trough body 12 to the second trough body 13 in the first horizontal direction, so that the material dripping on the top surface of the partition 11 flows into the first trough body 12, and then is discharged through the discharge port 14, reducing or avoiding flowing into the second trough body 13.

[0025] In a further embodiment, the top surface of the groove wall of the first groove body 12 away from the second groove body 13 is an inclined surface inclined upward from the first groove body 12 to the second groove body 13 in the first horizontal direction, that is, an inclined surface parallel to the top surface of the partition 11.

[0026] In a further embodiment, the highest point of the top surface of the groove wall of the first groove body 12 away from the second groove body 13 is higher than the highest point of the heating tube 2 located in the second groove body 13 .

[0027] In a further embodiment, the top surface of the groove wall of the first trough body 12 away from the second trough body 13 is a V-shaped surface centered on the discharge port 14 in the second horizontal direction, which is conducive to the glass liquid dripping on the top surface of the groove wall of the first trough body 12 away from the second trough body 13 to flow to the discharge port 14 and then be discharged, thereby avoiding structural hanging below the heater.

[0028] In a further embodiment, the bottom wall of the first trough body 12 is an inclined surface that is radially inclined downward from the outside to the inside with the discharge port 14 as the center, so as to better guide the flow.
