Description

Technical Field

[0001] This utility model relates to the field of fused silica production technology, specifically to a cooling device for fused silica production. Background Technology

[0002] Fused silica is produced by melting natural high-purity silica in an electric furnace at temperatures exceeding 1760 degrees Celsius, followed by rapid cooling. This process transforms crystalline silica into an amorphous glassy melt. Fused silica has a melting temperature of approximately 1713 degrees Celsius, low thermal conductivity, and one of the lowest coefficients of thermal expansion among all refractory materials, resulting in extremely high thermal shock resistance. Therefore, fused silica molds rarely crack due to drastic temperature changes during firing and casting, making it an ideal refractory material for investment casting. It can be used as a face or back coating, as well as a sand-spreading material. Cooling devices are required during the production of fused silica.

[0003] In existing technologies, cooling devices typically cool molten silica using a rotating drum placed inside a cooling chamber. This method makes it inconvenient to remove the molten silica after it has cooled inside the drum, affecting subsequent cooling progress and resulting in low cooling efficiency. A cooling device for molten silica production is needed to solve these problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cooling device for fused silica production, so as to solve the problems mentioned in the background art. This utility model has a reasonable structure, is easy to remove, and has high cooling efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for fused silica production, comprising: A cooling box, wherein a rotating cylinder for placing molten quartz is rotatably arranged inside the cooling box; The rotating drum has multiple cooling holes on its side wall. A second support frame is provided at the bottom of the cooling box. A rotating tube is provided at the bottom of the rotating drum, penetrating the bottom of the cooling box and rotatably connected to the second support frame.

A hydraulic cylinder is provided at the bottom of the second support frame, penetrating the bottom of the cooling box and connected to the sealing top plate. The telescopic shaft of the hydraulic cylinder is located inside the rotating tube and a connecting bearing is provided at the connection point with the sealing top plate.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figure 1 As shown, this utility model provides a technical solution: a cooling device for fused silica production, comprising: Cooling box 1, with a rotating cylinder 13 inside for placing molten quartz; The rotating drum 13 has multiple cooling holes 131 on its side wall. The bottom of the cooling box 1 is provided with a second support frame 9. The bottom of the rotating drum 13 is provided with a rotating tube 10 that penetrates the bottom of the cooling box 1 and is rotatably connected to the second support frame 9. The lower side of the inner wall of the rotating drum 13 is provided with a sealing top plate 12. The bottom of the second support frame 9 is provided with a hydraulic cylinder 8 that penetrates the bottom of the cooling box 1 and is connected to the sealing top plate 12. The telescopic shaft of the hydraulic cylinder 8 is located inside the rotating tube 10 and a connecting bearing 11 is provided at the connection with the sealing top plate 12. The bottom of the cooling tank 1 is equipped with a drive assembly 7 for rotating the rotating tube 10. This design drives the rotating tube 10 to rotate, which in turn drives the rotating drum 13 to rotate. Under the action of the coolant inside the cooling tank 1, the coolant enters the rotating drum 13 through the cooling holes 131 to rapidly cool the molten quartz. When the molten quartz needs to be removed after cooling, the coolant inside the cooling tank 1 is drained, and the rotating drum 13 throws the coolant off the molten quartz. Then, the hydraulic cylinder 8 drives the sealing top plate 12 to move upwards along the inner wall of the rotating drum 13, pushing the molten quartz upwards from inside the rotating drum 13 for easy removal. The rotating drum 13 saves time and improves subsequent cooling efficiency; by connecting the bearing 11, the hydraulic cylinder 8 is prevented from rotating when the sealing top plate 12 and the rotating drum 13 rotate; the inner diameter of the cooling hole 131 is larger than the fused silica, so the fused silica will not flow out from the cooling hole 131; wherein, under the action of the sealing top plate 12 and the lower side of the inner wall of the rotating drum 13, the coolant will not enter the interior of the rotating tube 10; if coolant appears inside the rotating tube 10, it can be discharged by opening a through hole in the side wall of the rotating tube 10 and sealing the through hole with a plug.

[0016] Reference Figure 3 , Figure 4 and Figure 6 The drive assembly 7 includes a first support frame 73 located at the bottom of the cooling tank 1. A drive motor 71 is mounted at the bottom of the first support frame 73. A second gear 74 is located inside the first support frame 73 on the output shaft of the drive motor 71. A first gear 72, located inside the second support frame 9 and meshing with the second gear 74, is located on the side wall of the rotating tube 10. This design allows the drive motor 71 in the drive assembly 7 to drive the second gear 74 to rotate, which in turn drives the rotating tube 10 to rotate. The rotating tube 10 then drives the rotating drum 13 to rotate, facilitating the rotation of the rotating drum 13 without affecting the hydraulic cylinder 8's drive of the sealing top plate 12 to remove the molten quartz.

[0017] Reference Figure 2 and Figure 3 A mounting plate 14 is provided on the upper side of the inner wall of the cooling box 1. A third sealed bearing 141 is provided at the connection between the rotating cylinder 13 and the mounting plate 14. A first sealed bearing 101 is provided at the connection between the rotating tube 10 and the second support frame 9. A second sealed bearing 102 is provided at the connection between the rotating tube 10 and the cooling box 1. This design improves the stability of the rotation of the rotating cylinder 13.

[0018] Reference Figure 4 and Figure 5The cooling box 1 is equipped with a cover plate 4 on top, an exhaust pipe 5 on top of the cover plate 4, and an exhaust collection groove 41 at the bottom of the cover plate 4 that communicates with the exhaust pipe 5. The mounting plate 14 is equipped with a connecting hole 142 at the bottom for connecting the exhaust collection groove 41 and the rotating drum 13. This design facilitates the discharge of gas from inside the rotating drum 13 into the cooling box 1 through the exhaust pipe 5, the exhaust collection groove 41, and the connecting hole 142.

[0019] Reference Figure 2 Multiple through-hole exhaust pipes 3 are provided at the connection between the bottom of the mounting plate 14 and the top of the cooling box 1. This design facilitates the discharge of gas from inside the cooling box 1 through the exhaust pipes 3.

[0020] Reference Figure 3 and Figure 6 Multiple stirring columns 132 are provided on the side wall of the rotating drum 13. This design uses the stirring columns 132 to stir the coolant inside the cooling tank 1, thereby improving the uniformity of cooling of the molten quartz inside the rotating drum 13; the uppermost stirring column 132 can stir the gas below the mounting plate 14, making it easier for the gas to be discharged from the exhaust pipe 3.

[0021] Reference Figure 1 and Figure 2 The cooling tank 1 has an inlet pipe 2 on its side wall, and an inlet valve 21 on the side wall of the inlet pipe 2. The cooling tank 1 also has an outlet pipe 6 on its side wall, and an outlet valve 61 on the side wall of the outlet pipe 6. This design facilitates the addition and discharge of coolant.

[0022] Reference Figures 1-6 As an embodiment of this utility model: when it is necessary to cool the molten quartz, the molten quartz to be cooled is placed inside the rotating cylinder 13 by opening the cover plate 4, and then the cover plate 4 is closed.

[0023] The drive motor 71 in the drive assembly 7 drives the second gear 74 to rotate, the first gear 72 drives the second gear 74 to rotate, the second gear 74 drives the rotating tube 10 to rotate, and the rotating tube 10 drives the rotating drum 13 to rotate. Under the action of the coolant inside the cooling tank 1, the coolant enters the rotating drum 13 through the cooling hole 131 to rapidly cool the molten quartz. The rotation of the rotating drum 13 drives the stirring column 132 to rotate, which stirs the coolant inside the cooling tank 1, improving the uniformity of the coolant's cooling of the molten quartz. The rotating drum 13 is not filled with molten quartz. The gas generated by cooling can be connected to the air at the bottom of the mounting plate 14 through the cooling hole 131 at the top, and the gas is discharged from the exhaust pipe 3 and the air outlet pipe 5. A PLC controller and a temperature sensor can be set as needed. The temperature sensor detects the temperature of the coolant inside the cooling tank 1. When the temperature is higher than the set value, it sends a signal to the PLC controller. The PLC controller controls the operation of the inlet valve 21 and the outlet valve to replace the coolant and lower the temperature of the coolant inside the cooling tank 1 to a suitable temperature.

[0024] When the molten quartz needs to be removed after cooling, the coolant inside the cooling tank 1 is drained, the rotating drum 13 rotates to throw off the coolant on the molten quartz, the cover plate 4 is opened, and then the hydraulic cylinder 8 drives the sealing top plate 12 to move upward along the inner wall of the rotating drum 13, pushing the molten quartz inside the rotating drum 13 upward, making it easier to remove the molten quartz from the rotating drum 13, saving time, improving the subsequent cooling efficiency, and improving the practicality of this utility model.
