[0036] How to improve the convenience of replacing heating elements, reduce maintenance time and downtime, simplify the replacement process, reduce the consumption of manpower and material resources, reduce the overall maintenance cost, and reduce the impact of replacement operations on glass production furnaces.

[0037] like Figure 1 As shown, the present invention provides a heating device for substrate glass production, comprising a heating device body, which can be installed in a glass production furnace to heat the glass production furnace; the heating device body comprises a chassis part and a heating element part, and the heating element part can be detachably arranged on the chassis part; wherein:

[0038] The chassis part includes a heating element accommodating body, the heating element accommodating body is connected with a replacement unit, the heating element accommodating body is arranged inside the glass production furnace, and the replacement unit is located outside the glass production furnace;

[0039] The heating element part can extend into or out of the heating element accommodating body along the replacement unit, and the heating element part includes a heating element and a locking unit connected to the heating element; the locking unit is detachably connected to the replacement unit so that the heating element part can be removed from or installed in the heating element accommodating body;

[0040] The heating element can be connected to an external monitoring control unit in order to regulate the temperature of the heating element and determine whether the heating element needs to be replaced.

[0041] In the current working conditions, when the heating equipment fails or is worn out during use, and the performance deteriorates and fails to meet the process requirements, it needs to be replaced. Due to the influence of space factors, the operation difficulty coefficient is high. Due to the influence of space factors, the existing replacement needs to take out the chassis together. In this way, due to the long time, the temperature in the furnace is naturally affected. For a long time, the temperature in the furnace will not be controlled, and the state of the glass side plate will change, affecting the product quality and subsequent stable production. In view of this situation, the present invention can improve the replacement of the heating equipment by designing the above-mentioned heating equipment. Unlike the previous need to take out the entire chassis, only the original heating element in the heating equipment needs to be replaced. In this way, the impact of the temperature fluctuation in the furnace on the guide plate during the replacement can be reduced, and the possibility of crystallization can be reduced or even eliminated, thereby improving the production stability of the glass furnace. The heating equipment of the present invention has a convenient structure, strong operability, easy replacement, and a high degree of use.

[0042] In some embodiments, the heating device for substrate glass production of the present invention includes a heating element accommodating frame 1 on the bottom plate, one side of the heating element accommodating frame 1 is connected to the replacement unit, and the heating element accommodating frame 1 can be installed in a glass production furnace. The present invention makes the overall structure of the heating device clearer and easier to install and maintain through the heating element accommodating frame 1, and enhances the stability of the heating device in the glass production furnace through the connection between the heating element accommodating frame 1 and the replacement unit.

[0043] As an embodiment, the replacement unit of the present invention includes a baffle 2 connected to a heating element accommodating frame 1, and the baffle 2 is provided with a first mounting hole 3, and the first mounting hole 3 is provided with a first positioning member, and the first positioning member can fix the heating element accommodating frame 1 to the glass production furnace by means of the first mounting hole 3. The present invention fixes the heating element accommodating frame 1 to the glass production furnace through the first mounting hole 3 by means of a preset first mounting hole 3 in combination with the first positioning member, thereby improving the stability of the equipment. In actual working conditions, the first positioning member can be a detachable positioning member such as a bolt. Furthermore, the baffle 2 of the present invention is provided with a through slot 4 at a middle position along the direction of the heating element accommodating frame 1, and the heating element can movably pass through the through slot 4. The present invention makes it easier to extend and extend the heating element through the design of the through slot 4, thereby improving the replacement efficiency. The through slot 4 can also protect the heating element to a certain extent to avoid damage during the replacement process.

[0044] In a heating device for substrate glass production of the present invention, the locking unit includes a fixing plate 5 that can be sleeved on a heating element, the fixing plate 5 is provided with a second mounting hole 6, the baffle 2 is provided with a third mounting hole 7 corresponding to the second mounting hole 6, and the second mounting hole 6 and the third mounting hole 7 are connected by a detachable connecting piece. The present invention ensures the stable locking of the heating element through the detachable connection between the second mounting hole 6 and the third mounting hole 7. In actual working conditions, the detachable connecting piece can be a detachable connecting piece such as a bolt, and the detachable connecting piece design makes the removal of the heating element more convenient and quick. The fixing plate 5 of the present invention can be installed in the through groove 4, and the shapes of the fixing plate 5 and the through groove 4 are adapted to each other, so that the installation is more stable and loosening is avoided during the heating process. The adapted shape reduces the friction between the fixing plate 4 and the through groove 5, and the service life of the heating device is extended.

[0045] In addition, the heating element of the present invention has a first terminal 8 and a second terminal 9, and the first terminal 8 and the second terminal 9 can be connected to a first cable connection 10 and a second cable connection 11 respectively, and the first cable connection 10 and the second cable connection 11 are connected to the monitoring control unit. The connection between the terminal and the cable connection ensures a reliable connection between the heating element and the monitoring control unit, and the design of the cable connection makes it easy to disconnect and reconnect the cable when the heating element needs to be replaced. The monitoring control unit of the present invention controls the temperature of the heating element in real time, and determines whether the degree of damage of the heating element needs to be replaced based on the temperature parameters, and then reminds the operation and maintenance personnel to replace the heating element part in the heating device of the present invention to ensure the overall stability of the glass production furnace.

[0046] The heating element of the present invention adopts a silicon-molybdenum rod heating element 12, which is a rod-shaped structure, and has an arc-shaped rod portion and a straight rod portion. In a specific embodiment, the silicon-molybdenum rod heating element 12 includes a curved heating portion and a straight rod portion connected to a terminal. The rod-shaped structure and the design of the arc-shaped and straight rod portions are convenient for disassembly and assembly, and can make the heating element better adapt to the heating requirements in a glass production furnace.

[0047] The present invention also provides a method for replacing a heating device in substrate glass production. When a monitoring control unit detects that a heating element needs to be replaced, the heating element is replaced according to the following steps:

[0050] S3. Connect the heating element to the monitoring control unit again to complete the replacement of the heating device.

[0051] The heating device of the present invention keeps the chassis part stationary. When the heating device needs to be replaced, only the heating element part needs to be removed and then replaced and installed. This can avoid the impact on the glass furnace during the replacement operation and improve the overall processing stability. The present invention can be suitable for substrate glass with a thickness of 0.5 mm and a substrate glass with a thickness of 0.45 mm in the future.

[0052] The present invention discloses a heating device for substrate glass production, wherein a silicon-molybdenum rod heating element 12 is installed on a sillimanite chassis, fixed by a fixing plate 5, and locked by bolts, thereby realizing replacement, installation and fixation of the heating element. The present invention adopts a one-time installation and fixation of the chassis on the chassis part, and there is no need to take out the chassis part, and only the internal heating element part needs to be taken out, so the installation is convenient and quick. The present invention places the internal heating part flat on a fixed chassis, and fixes the heating element by a fixing plate 5, so the operation is simple and the risk factor is small. The present invention can avoid the fluctuation of the temperature in the furnace caused by the heating element replacement operation, thereby improving the quality of the processed products, greatly shortening the operation time, and extending the service life of the equipment. It also reduces the potential safety hazards of personnel in the replacement operation to a certain extent, and has good adaptability.
