Description

Technical Field

[0001] This utility model relates to the field of optical glass manufacturing technology, specifically to a stirrer for the uniformity of optical glass. Background Technology

[0002] As a core material for precision optical instruments such as lenses, prisms, and optical fibers, the performance of optical glass directly depends on the uniformity of its composition and the integrity of its microstructure. It also ensures that the chemical composition and bubble level in the melt are up to standard and free from streaks or crystallization defects. Melt stirring is a key process step to achieve this goal. Stirring breaks up the component stratification of the melt, promotes the rise of bubbles, and avoids introducing new process defects. However, traditional optical glass processing involves stirring the melt at "segmented fixed speeds," which cannot adapt to the dynamic changes in melt viscosity in real time. If the speed is too high, bubbles may enter the melt; if the speed is too low, homogenization efficiency may be insufficient, leading to defects in later processing and significantly increasing the scrap rate in subsequent production. Utility Model Content

[0003] The purpose of this invention is to provide a stirrer for the uniformity of optical glass, so as to solve the problem mentioned in the background art that the scrap rate is easily increased due to uneven stirring.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a stirrer for optical glass homogeneity, comprising a heat-insulated tank, a top cover being inserted and installed on the outer surface of the heat-insulated tank, and the top cover and the heat-insulated tank being concentrically designed; a controllable speed-adjustable motor being fixedly installed on the outer surface of the top cover, and the output end of the controllable speed-adjustable motor passing through the outer surface of one end of the top cover; a dynamic torque sensor being fixedly installed on the side surface of the top cover, and one end of the dynamic torque sensor being connected to the controllable speed-adjustable motor; and a first synchronous pulley being rotatably installed on the outer surface of the top cover, and the first synchronous pulley being connected to the dynamic torque sensor.

[0005] Preferably, a vortex heating tube is fixedly installed inside the heat insulation tank, and one end of the vortex heating tube penetrates the side surface of the heat insulation tank. A controller is placed on the ground on one side of the heat insulation tank and is connected to the vortex heating tube.

[0006] Using the above technical solution, the eddy current heating tube can be controlled by the controller, and the eddy current heating tube can be used to heat the inner liner, so that the optical glass material stored inside the inner liner can be heated and melted quickly, without causing the heat insulation tank to generate a high temperature.

[0007] Preferably, the interior of the heat insulation tank is provided with a groove, and a heating inner liner is inserted and installed in the groove of the heat insulation tank, and the heating inner liner and the heat insulation tank are designed concentrically.

[0008] By adopting the above technical solution, the heat-insulating tank placed inside the heating inner liner can be limited, so that the vortex heating tube can be kept in the middle when heating the heating inner liner, thereby improving the heating efficiency and heating quality of the vortex heating tube on the heating inner liner.

[0009] Preferably, a plug sleeve is rotatably mounted on the outer surface of the top cover, and a second synchronous pulley is fixedly mounted on the outer surface of the plug sleeve. A synchronous belt is provided between the second synchronous pulley and the first synchronous pulley, and the synchronous belt engages with the second synchronous pulley and the first synchronous pulley respectively. The diameter of the first synchronous pulley is smaller than the diameter of the second synchronous pulley.

[0010] By adopting the above technical solution, the diameter difference between the second synchronous pulley and the first synchronous pulley can make the agitator blade rotate more easily, ensure the accuracy of the agitator blade rotation, and reduce the probability of the agitator blade slipping and failing to rotate.

[0011] Preferably, a coupling rotating rod is inserted and installed on the outer surface of the insert sleeve, and the coupling rotating rod is designed as a square shaft. The coupling rotating rod engages with the insert sleeve. A fixing bolt is threaded on the outer surface of the insert sleeve, and the fixing bolt is in contact with the outer surface of the coupling rotating rod. The coupling rotating rod and the heat insulation tank are designed to be concentric.

[0012] By adopting the above technical solution, the square shaft design of the coupling rotating rod makes it more secure when inserted into the plug sleeve for rotation, and the coupling rotating rod can be fixed by tightening the fixing bolts, making it easier to replace the coupling rotating rod and the agitator blade.

[0013] Preferably, an agitator is fixedly installed on the outer surface of the coupling rotating rod, and the agitator is designed to be inclined, and agitator teeth are evenly arranged on the outer surface of the agitator.

[0014] By adopting the above technical solution, the stirring teeth can make the stirring blades rotate more thoroughly to stir the melt, thereby further improving the stirring effect of the melt.

[0015] Preferably, a rotating top block is rotatably mounted on the outer surface of the coupling rotating rod, and the outer surface of the rotating top block is in contact with the inner surface of the heated inner liner, and the heated inner liner and the rotating top block are concentrically designed.

[0016] By adopting the above technical solution, the rotating top block can come into contact with the heated inner liner, making the stirring blades and stirring teeth more stable and secure when rotating, and further improving the stirring effect of the stirring blades and stirring teeth.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the optical glass homogeneity stirrer: 1. By installing and using a dynamic torque sensor, the torque of the controllable speed motor can be monitored during rotation. Combined with the heating of the inner heating chamber by the eddy current heating tube and the use of the controller, the speed of the controllable speed motor can be flexibly adjusted according to the resistance encountered when stirring the optical glass molten material at different stages of heating. The dynamic torque sensor can also be easily disassembled and replaced, allowing the optical glass material to be stirred in the best condition at different stages, greatly improving the quality of the optical glass material during stirring. 2. The eddy current heating tube can heat the inner liner to rapidly increase the melting speed of the glass material inside the inner liner. The heat insulation tank can keep the inner liner warm, and the engagement between the inner liner and the groove of the heat insulation tank can ensure the concentricity of the inner liner when inserted into the heat insulation tank, so that the inner liner can be heated better and greatly improve the quality of heating and melting of the glass raw materials. 3. By rotating the first synchronous pulley and using the synchronous belt, the second synchronous pulley can be driven to rotate, allowing the plug sleeve to rotate and drive the coupling rotating rod to rotate. This allows the stirring blade to stir the optical glass material stored inside the heated inner tank, greatly reducing the chance of the synchronous belt slipping due to excessive resistance during stirring. This ensures that the molten optical glass can be stirred stably and continuously, guaranteeing the stirring quality of the optical glass. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-6 This utility model provides a technical solution: a stirrer for optical glass homogeneity, comprising an insulated tank 1, a top cover 5 inserted and installed on the outer surface of the insulated tank 1, and the top cover 5 and the insulated tank 1 being concentrically designed; an eddy current heating tube 2 fixedly installed inside the insulated tank 1, with one end of the eddy current heating tube 2 penetrating through the side surface of the insulated tank 1; a controller 3 placed on the ground on one side of the insulated tank 1, and the controller 3 being connected to the eddy current heating tube 2; and a groove provided inside the insulated tank 1. A heating inner liner 4 is inserted into the groove, and the heating inner liner 4 and the heat insulation tank 1 are concentrically designed. A controllable speed motor 6 is fixedly installed on the outer surface of the top cover 5, and the output end of the controllable speed motor 6 passes through the outer surface of one end of the top cover 5. A dynamic torque sensor 7 is fixedly installed on the side surface of the top cover 5, and one end of the dynamic torque sensor 7 is connected to the controllable speed motor 6. A first synchronous pulley 8 is rotatably installed on the outer surface of the top cover 5, and the first synchronous pulley 8 is connected to the dynamic torque sensor 7.

[0022] First, the optical glass material needs to be placed into the heating inner liner 4 before use. The heating inner liner 4 is then inserted into the heat-insulating tank 1, and the top cover 5 is closed. The controller 3 then controls and monitors the electronic components, including the eddy current heating tube 2, the controllable speed motor 6, and the dynamic torque sensor 7. This allows the eddy current heating tube 2 to heat the heating inner liner 4, ensuring the optical glass material inside is heated quickly and evenly. The dynamic torque sensor 7 monitors the torque of the controllable speed motor 6. Combined with the monitoring and operation of the controller 3, the rotation speed of the controllable speed motor 6 is adjusted in real time according to the stirring torque as the optical glass material gradually melts. This allows for different rotation speeds at different stages of the melting process, significantly improving the stirring quality of the optical glass material during melting and greatly reducing the scrap rate.

[0023] A plug sleeve 9 is rotatably mounted on the outer surface of the top cover 5, and a second synchronous pulley 10 is fixedly mounted on the outer surface of the plug sleeve 9. A coupling rotating rod 12 is plugged into the outer surface of the plug sleeve 9, and the coupling rotating rod 12 is designed as a square shaft. The coupling rotating rod 12 engages with the plug sleeve 9. A fixing bolt 13 is threaded on the outer surface of the plug sleeve 9, and the fixing bolt 13 is in contact with the outer surface of the coupling rotating rod 12. The coupling rotating rod 12 and the heat insulation tank 1 are concentrically designed. A synchronous belt 11 is provided between the second synchronous pulley 10 and the first synchronous pulley 8, and the synchronous belt 11 engages with both the second synchronous pulley 10 and the first synchronous pulley 8. The diameter of the first synchronous pulley 8 is smaller than the diameter of the second synchronous pulley 10.

[0024] Secondly, the insertion and square shaft design of the insert sleeve 9 and the coupling rotating rod 12 makes it easier to insert the coupling rotating rod 12 and the insert sleeve 9. The installation, disassembly and maintenance can be easily carried out by tightening and fixing the fixing bolt 13. The use of the first synchronous pulley 8 and the synchronous belt 11 can drive the second synchronous pulley 10 to rotate, so that the coupling rotating rod 12 connected to the insert sleeve 9 can rotate together. The use of the first synchronous pulley 8, the second synchronous pulley 10 and the synchronous belt 11 can improve the stability of the coupling rotating rod 12 during rotation, so that the coupling rotating rod 12 will not slip during rotation, which would cause uneven stirring of the optical glass, and greatly improve the uniformity and quality of the optical glass material stirring.

[0025] A stirring blade 14 is fixedly installed on the outer surface of the coupling rotating rod 12. The stirring blade 14 is designed to be inclined, and stirring teeth 15 are evenly arranged on the outer surface of the stirring blade 14. A rotating top block 16 is rotatably installed on the outer surface of the coupling rotating rod 12. The outer surface of the rotating top block 16 is in contact with the inner surface of the heating inner liner 4, and the heating inner liner 4 and the rotating top block 16 are designed to be concentric.

[0026] Furthermore, after the coupling rotating rod 12 is inserted into the interior of the heated inner liner 4, the rotating top block 16 will come into contact with the heated inner liner 4. As the stirring blade 14 is driven to rotate, it will stir the material inside the heated inner liner 4. The stirring teeth 15 will improve the stirring quality of the optical glass material. At the same time, it can improve the stability of the heated inner liner 4 placed in the heat-insulating tank 1, greatly improve the stirring quality of the optical glass during stirring, and greatly improve the stability of the coupling rotating rod 12 during rotation.

[0027] Working principle: In use, simply put the optical glass material into the heating inner liner 4, ensuring that the heating inner liner 4 fits into the groove inside the heat-insulating tank 1. Then, insert the coupling rotating rod 12 into the heating inner liner 4 and place the top cover 5 on the outer surface of the heat-insulating tank 1. Subsequently, the controller 3 allows the eddy current heating tube 2 to heat the heating inner liner 4, allowing the optical glass material inside to be rapidly heated and gradually melted. Then, the rotation of the controllable speed motor 6 is controlled by the rotation of the variable speed motor 6, and the torque of the variable speed motor 6 is monitored by the dynamic torque sensor 7. When the stirring blade 14 stirs the optical glass material, the rotation speed of the controllable speed motor 6 can be changed according to the torque of the coupling rotating rod 12. This allows the stirring and rotation speed of the optical glass material to be automatically adjusted under different conditions, ensuring the stirring quality of the optical glass material and greatly reducing the probability of producing defective optical glass.
