[0002] In the glass manufacturing process, ensuring the stability and uniformity of the furnace wall temperature is an indispensable key link in improving the quality of glass products. In view of this core demand, technical experts in this field continue to invest in research and development, striving to optimize existing technologies. For example, the kiln and glass production method disclosed in Chinese patent CN113754245A is an innovative design that aims to promote the backward flow of horizontal and vertical circulation by adjusting the hot spot position in the furnace. This structure not only increases the melting temperature of the kiln and meets the needs of ultra-high temperature production, but also significantly enhances the clarification effect of the rear area of ​​the furnace, effectively reducing quality problems such as bubbles. However, although the above scheme has made significant progress in improving kiln performance, it still faces some challenges: traditional heating methods often make it difficult to ensure uniform temperature distribution, and are accompanied by high energy consumption. These problems directly affect the molding accuracy and production efficiency of glass products. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a uniform heating structure for the furnace wall of a glass furnace and a heating device thereof.

[0004] The technical solution adopted by the present invention is as follows:

[0005] A uniform heating structure for a furnace wall of a glass furnace comprises a vertical frame-type heating unit, which is attached to the outer surface of the furnace wall of the glass furnace to keep the temperature inside the furnace wall constant; the heating unit comprises a protective cover plate, a lifting frame, a main heating channel and a sub-heating channel, wherein:

[0006] A protective cover plate is installed on the top of the heating unit to prevent impurities from entering the interior of the heating unit;

[0007] The lifting frame is installed on the side of the heating unit. A plug-in round hole and a docking square hole are provided on one side of the lifting frame, and a matching plug-in rod and a docking joint are provided on the other side of the lifting frame, which are used to splice adjacent lifting frames into one;

[0008] The main heating channel is arranged transversely on the side of the lifting frame, and a high temperature resistant heating wire is arranged inside the main heating channel to provide electrical energy to the entire heating unit;

[0009] The sub-heating channels are arranged at equal intervals between the main heating channels. They are Z-shaped bending structures, including vertical pipeline I, inclined pipeline and vertical pipeline II connected to the main heating channel, wherein:

[0010] Vertical pipeline I, with metal heat conducting rods on both sides, is used to evenly distribute the temperature of the heating wire throughout the entire heating unit;

[0011] An inclined pipeline, which connects the vertical pipeline I and the vertical pipeline II, is used to expand the area of ​​the sub-heating channel;

[0012] A temperature sensor is arranged on one side of the vertical pipeline II to detect whether the temperature of the heating wire meets the requirement of constant temperature.

[0013] This technical solution controls the temperature inside the furnace wall through heating wires, metal heat-conducting rods, sub-heating channels and temperature sensors, ensuring temperature uniformity during the glass production process. Specifically, the vertical frame structure ensures that the heating unit is stably installed on the outer surface of the furnace wall and is not easily displaced or deformed due to temperature changes or external factors; the lifting frame and splicing mechanism, including plug-in round holes, docking square holes, plug-in rods and docking joints, are assembled and disassembled in a modular manner, which is convenient for installation, maintenance and replacement of parts, and also improves the flexibility of the overall structure; the metal heat-conducting rods on both sides of the vertical pipeline I effectively distribute the heat generated by the heating wire evenly throughout the heating unit, reducing thermal resistance and improving the efficiency of heat energy transfer; the Z-shaped bending structure of the sub-heating channel, including vertical pipeline I, inclined pipeline, and vertical pipeline II, not only increases the surface area of ​​the heating element, but also expands the radiation range of heat through the inclined pipeline, so that the heat is more evenly distributed on the outer surface of the furnace wall, thereby better controlling the temperature in the furnace; the temperature sensor arranged on one side of the vertical pipeline II monitors the temperature of the heating wire in real time to ensure accurate temperature control during the heating process; the protective cover is used to prevent impurities from entering the interior of the heating unit, protect the heating element from external pollution and damage, and extend the service life.

[0014] In addition, the uniform heating structure of the furnace wall of the glass furnace proposed in the present invention also has the following additional technical features:

[0015] According to one embodiment of the present invention, the main heating channel is a hollow pipe with a heating wire disposed therein; an interface for serially connecting adjacent main heating channels is disposed on the side of the main heating channel.

[0016] In this technical solution, the main heating channel is a hollow structure with a built-in heating wire, and an interface for serially connecting adjacent main heating channels is provided to achieve effective transfer of heat energy and flexible connection of heating units, thereby ensuring the scalability of the furnace wall heating area.

[0017] According to one embodiment of the present invention, the sub-heating channel is a flat structure with a heating wire built in it; the metal heat-conducting rod is connected to the heating wire in the vertical pipeline I; and there is a gap between adjacent metal heat-conducting rods.

[0018] This technical solution adopts a flat structure to divide the heating channel into built-in heating wires, and connects the metal heat-conducting rods with the heating wires in the vertical pipeline I, while retaining gaps between adjacent metal heat-conducting rods to optimize the distribution of thermal energy, improve the heating efficiency, and promote uniform heat distribution.

[0019] According to an embodiment of the present invention, the lifting frame is a sleeve structure, which is used to drive the protective cover plate located thereon to be flush with the top edge of the furnace wall.

[0021] According to an embodiment of the present invention, the lifting frame is further provided with fixing bolts, which are respectively fixed to the four end corners of the lifting frame and matched with the mounting holes on the furnace wall.

[0022] The technical solution realizes the stable installation of the heating unit by arranging fixing bolts at the four end corners of the lifting frame and matching them with the mounting holes on the furnace wall.

[0023] According to an embodiment of the present invention, the lifting frame is further provided with a gripping portion, and the gripping portion is fixed to the front side of one side of the lifting frame.

[0024] This technical solution provides a convenient gripping point for the operator by arranging a gripping portion on the front side of one side of the lifting frame, thereby facilitating the adjustment and movement of the lifting frame and improving the operating efficiency.

[0025] According to an embodiment of the present invention, the Z-shaped bending directions of all the sub-heating channels are the same.

[0026] This technical solution ensures that the Z-shaped bending directions of all sub-heating channels are the same, so as to achieve regularity and consistency of heat flow inside the heating unit, promote uniform distribution of furnace wall temperature, and improve heating effect.

[0033] According to one embodiment of the present invention, a heat insulating layer is disposed on the outer side of the heating unit, and a multi-layer reflective plate is disposed on the inner surface of the heat insulating layer for reflecting the heat emitted by the heating unit back into the furnace.

[0034] This technical solution achieves the effect of effectively reducing heat loss and enhancing heat reflection into the furnace by setting an insulating layer on the outside of the heating unit and configuring a multi-layer reflective plate on the inner surface of the insulating layer, thereby improving the heating efficiency and maintaining the stability of the temperature in the furnace.

[0035] According to one embodiment of the present invention, ventilation holes and exhaust ducts are also provided on the furnace wall to discharge excess heat generated in the furnace.
