Description
Technical Field
[0001] The utility model relates to the technical field of glass processing, in particular to a high-temperature homogenization device for optical glass. Background Art
[0002] In the production process of optical glass, high-temperature homogenization is a crucial link, which determines the quality and performance of optical glass. Most of the high-temperature homogenization devices currently on the market use a single heat source for heating, lacking uniform heating of the glass plate, resulting in a temperature gradient in the glass plate during the heating process, affecting the optical performance. In addition, these devices usually do not have a preheating function, resulting in inconsistent temperatures of the glass plate before entering the homogenization furnace, further exacerbating the difficulty of homogenization. Therefore, the development of an optical glass high-temperature homogenization device with preheating and multi-dimensional heating functions has become an urgent need in the current industry. Utility Model Content
[0003] The purpose of the utility model is to provide a high-temperature homogenization device for optical glass to solve the problems raised in the above-mentioned background technology.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-temperature homogenization device for optical glass, comprising a conveyor rack, a preheating box and a high-temperature box, wherein a preheating box is installed on one side of the top of the conveyor rack, and a high-temperature box is installed on the other side of the top of the conveyor rack, partition assemblies are arranged on both sides of the preheating box and the high-temperature box, two groups of first heating devices are arranged inside the preheating box, twelve groups of first heating devices are arranged inside the high-temperature box, the first heating device is composed of a silicon carbon rod and a heat conducting sheet, a second heating device is arranged inside the conveyor rack, and the second heating device is located below the conveyor belt.
[0005] The preheating box and the high-temperature box of the device are made of high-temperature resistant materials. The cavity formed therein can provide a processing position for the glass, and a plurality of temperature sensors are arranged inside the cavity. The temperature is monitored and adjusted in real time in cooperation with the control unit of the external device to ensure the stability of the heat-matching effect. Because the existing well-known technology is adopted, it is not described in detail in this application. When in use, the glass to be processed is placed on the conveyor belt, and the glass is transported to the inside of the preheating box by the operation of the conveyor belt, and the partition assembly is closed. At this time, the first heating device inside the preheating box is started to make the glass evenly preheated inside the preheating box, so as to realize the initial preheating of the glass plate and effectively reduce the glass plate in the evenly heated state. The stress generated by inconsistent temperature during the homogenization process improves the homogenization quality of the optical glass. After the preheating is completed, the partition assembly is opened, and the glass is continued to be transported to the inside of the high-temperature box through the conveyor belt. At this time, the partition assemblies on both sides of the high-temperature box are closed, and the first heating device inside the high-temperature box is started. At the same time, the second heating device is started to heat the glass to the required temperature. Due to the simultaneous heating of the first heating device and the second heating device, all-round and uniform heating of the glass plate can be achieved. Through the application of multi-dimensional heating, the glass plate can be heated from multiple directions, eliminating the temperature gradient caused by heating from a single heat source, and further improving the performance of the optical glass.
[0006] Preferably, the partition assembly includes an electric push rod and a thermal insulation partition, and the thermal insulation partition is installed at the output end of the electric push rod.
[0007] The operation of the electric push rod can push the thermal insulation partition, and the high-temperature box and preheating box can be closed by lowering the thermal insulation partition to avoid heat loss.
[0008] Preferably, the silicon carbon rod is designed to be bent, and the heat conducting sheet is in contact with the silicon carbon rod.
[0009] The silicon carbon rod is a high-temperature electric heating element. Because the silicon carbon rod adopts a curved design, the silicon carbon rod and the heat conductive sheet have a larger contact surface, and the heat of the silicon carbon rod can be better dissipated through the heat conductive sheet.
[0010] Preferably, supporting feet are equidistantly installed at the bottom of the conveying frame, and a conveyor belt is arranged at the top of the conveying frame.
[0011] The conveyor rack can be stably placed at a designated position through the supporting legs, making it convenient to use. The glass that needs to be homogenized can be transported through the operation of the conveyor belt, so that the glass enters the preheating box and the high-temperature box in turn.
[0012] In summary, this application includes the following beneficial technical effects:
[0013] 1. The utility model adopts the coordinated use of preheating and high temperature to uniformly preheat the glass inside the preheating box, realizes the initial preheating of the glass plate, effectively reduces the stress generated by the inconsistent temperature of the glass plate during the homogenization process, and improves the homogenization quality of the optical glass.
[0014] 2. When the utility model is used, due to the simultaneous heating of the first heating device and the second heating device, all-round and uniform heating of the glass plate can be achieved. Through the application of multi-dimensional heating, the glass plate can be heated from multiple directions, eliminating the temperature gradient caused by heating with a single heat source, and further improving the performance of the optical glass.

[0030] Embodiment 1
[0031] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model proposes an optical glass high-temperature homogenization device, comprising a conveyor frame 1, a preheating box 2 and a high-temperature box 3. The preheating box 2 is installed on one side of the top of the conveyor frame 1, and the high-temperature box 3 is installed on the other side of the top of the conveyor frame 1. Partition assemblies 4 are arranged on both sides of the preheating box 2 and the high-temperature box 3. Two groups of first heating devices 5 are arranged inside the preheating box 2, and twelve groups of first heating devices 5 are arranged inside the high-temperature box 3. The first heating device 5 consists of a silicon carbon rod 501 and a heat conducting sheet 502. A second heating device 6 is arranged inside the conveyor frame 1, and the second heating device 6 is located below the conveyor belt 101.
[0032] The working principle of the optical glass high-temperature homogenization device based on the first embodiment is as follows: the preheating box 2 and the high-temperature box 3 of the device are made of high-temperature resistant materials, and the cavity formed therein can provide a processing position for the glass, and a plurality of temperature sensors are arranged inside the cavity, which cooperate with the control unit of the external device to monitor and adjust the temperature in real time to ensure the stability of the homogenization effect. Because the existing well-known technology is adopted, it is not described in detail in this application. When in use, the glass to be processed is placed on the conveyor belt 101, and the glass is transported to the inside of the preheating box 2 through the operation of the conveyor belt 101, and the partition assembly 4 is closed. At this time, the first heating device 5 inside the preheating box 2 is started to uniformly preheat the glass inside the preheating box 2, thereby achieving the initial preheating of the glass plate. Heat is used to effectively reduce the stress of the glass plate caused by temperature inconsistency during the homogenization process, thereby improving the homogenization quality of the optical glass. After preheating is completed, the partition assembly 4 is opened, and the glass is continued to be transported to the interior of the high temperature box 3 through the conveyor belt 101. At this time, the partition assemblies 4 on both sides of the high temperature box 3 are closed, and the first heating device 5 inside the high temperature box 3 is started. At the same time, the second heating device 6 is started to heat the glass to the required temperature. Due to the simultaneous heating of the first heating device 5 and the second heating device 6, all-round and uniform heating of the glass plate can be achieved. Through the application of multi-dimensional heating, the glass plate can be heated from multiple directions, eliminating the temperature gradient caused by heating with a single heat source, thereby further improving the performance of the optical glass.
