Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass furnace technology, specifically a glass furnace bubble removal mechanism. Background Technology
[0002] A glass melting furnace is a thermal equipment used in glass manufacturing to melt glass batches. Powders and molten glass (crushed glass) prepared according to the glass composition are melted and clarified at high temperatures in the furnace to form molten glass that meets the forming requirements. After the glass raw materials are softened at high temperatures in an oxygen-filled glass furnace, air is easily mixed into the softened glass, which leads to the formation of bubbles inside the glass and affects the forming and appearance of the glass.
[0003] In a Chinese patent for a degassing device for an all-oxygen glass furnace (patent number: CN222205028U), the device includes an outer shell, an inner shell, a crucible, a stirring rod, and a lifting transmission structure. Heating coils are equidistantly installed on the inner wall of the inner shell, and a placement base is fixedly installed on the lower outer surface of the inner shell. A vibrating plate is detachably installed on the upper middle part of the placement base, and an elastic washer is fixedly connected to the gap between the placement base and the vibrating plate. This device can oscillate, stir, and continuously heat the softened glass to eliminate bubbles in the softened glass. This structure can increase the degassing methods for softened glass and improve the degassing efficiency of the device. Secondly, during the degassing process of softened glass, it can cover the space above the softened glass to prevent external impurities from being mixed into the glass raw material and causing the generation of bubbles. It can eliminate bubbles in the softened glass more quickly and further improve the quality and aesthetics of the glass. However, this device only uses mechanical stirring to process the glass raw liquid for degassing, which is a relatively simple method and the degassing effect is generally average.

[0004] To address the problems mentioned in the background art, this utility model provides the following technical solution: a degassing mechanism for a glass furnace, comprising an outer tank and an inner liner located within the outer tank. A support frame is fixedly connected to the bottom of the outer tank. An inlet valve communicating with the inner liner is provided on the upper left side of the outer tank. An outlet valve communicating with the inner liner is provided on the bottom of the outer tank. An exhaust valve communicating with the inner liner is provided on the top of the outer tank. A lifting and stirring mechanism is provided in the upper middle region of the inner liner. A cover is fixedly connected to the lower right side of the outer tank. A clarifying agent inlet pipe is fixedly inserted into the right side wall of the cover. A rotating pipe is rotatably connected to the inner end of the clarifying agent inlet pipe via a rotating sleeve. A rotating mechanism is provided on the cover. One end of the rotating mechanism is fixedly connected to the rotating pipe. The rotating pipe extends through the inner liner and is connected to uniformly distributed liquid outlets.
[0005] As a further embodiment of this utility model: the lifting and stirring mechanism includes a stirring motor fixed to the top of the outer tank, the main shaft of the stirring motor penetrating into the inner liner and fixedly connected to an inner rotating rod, an outer cylinder sleeved and slidably connected to the inner rotating rod, guide rails fixedly connected to both side walls of the inner rotating rod, guide grooves slidably connected to the guide rails on both inner walls of the outer cylinder, a fixed rod fixedly connected to the inner top wall of the inner liner, a slider fixedly connected to the lower end of the fixed rod, an annular inclined groove slidably connected to the slider on the upper part of the outer side wall of the outer cylinder, and a spiral blade fixedly connected to the outer side wall of the outer cylinder.
[0006] As a further embodiment of this utility model: the top of the outer tank is provided with a first through hole that communicates with the inner liner, and the first through hole is rotatably connected to the main shaft end of the stirring motor through a first bearing component.

[0010] As a further embodiment of this utility model, the outer wall of the rotating tube located in the inner liner is fixedly connected with uniformly arranged stirring teeth.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model, by setting up a clarifying agent inlet pipe, a rotating pipe and an outlet head, allows the clarifying agent to be introduced into the rotating pipe through the clarifying agent inlet pipe, and then directly introduced into the inner side of the glass melt through the outlet head. This allows the clarifying agent to release gas directly inside the glass melt, causing the bubbles in the glass melt to absorb the gas, expand and float to the surface of the glass melt and eventually break, thus completing the removal of bubbles inside the glass melt. In addition, this device has a sealed structure, which can prevent external impurities from contaminating the glass melt and ensure the processing quality.
[0013] 2. This utility model, by setting up a lifting and stirring mechanism, when the stirring motor is started, can drive the inner rotating rod to rotate, which in turn drives the spiral blades on the outer cylinder to rotate, thus stirring the glass raw liquid. At the same time, when the outer cylinder rotates, due to the sliding between the annular inclined groove and the slider, and the sliding connection between the guide groove and the guide strip, the outer cylinder reciprocates and moves up and down on the inner rotating rod, which can realize the simultaneous rotation and up and down movement of the spiral blades, thereby improving the stirring effect of the glass raw liquid and thus improving the de-bubbling effect.
[0014] 3. This utility model, by setting up a rotating mechanism, starts the drive motor to work, which can drive the active bevel gear to rotate. Since the active bevel gear meshes with the driven bevel gear, it can drive the rotating tube to rotate, and then drive the stirring teeth to rotate, so as to stir the glass raw liquid. At the same time, it makes the clarified liquid sprayed from the liquid outlet more fully contact the glass raw liquid, and improves the de-bubbling effect. Attached Figure Description

[0022] Please see Figures 1-5This embodiment provides a degassing mechanism for a glass furnace, comprising an outer tank 1 and an inner liner 2 located within the outer tank 1. A support frame 3 is fixedly connected to the bottom of the outer tank 1, and a control switch is installed on the support frame 3. All electrical equipment of this device is electrically connected to the control switch. The circuitry involved is existing technology and can be fully implemented by those skilled in the art, so no further explanation is needed. The upper left side of the outer tank 1 is provided with a feed valve port 4 communicating with the inner liner 2 and connected to the discharge end of the all-oxygen glass furnace. The bottom of the outer tank 1 is provided with a discharge valve port 5 communicating with the inner liner 2 to discharge the degassed glass liquid. The top of the outer tank 1 is provided with an exhaust valve port 6 communicating with the inner liner 2 to discharge the gas bubbles in the liquid. A lifting and stirring mechanism is provided in the upper middle area of the inner liner 2. A cover 7 is fixedly connected to the lower right side of the outer tank 1. A clarifying agent inlet pipe 8 is fixedly inserted into the right side wall. The inner end of the clarifying agent inlet pipe 8 is rotatably connected to a rotating pipe 9 via a rotating sleeve. A rotating mechanism is provided on the cover 7. One end of the rotating mechanism is fixedly connected to the rotating pipe 9. The rotating pipe 9 extends through the inner liner 2 and is connected to a uniformly distributed liquid outlet 10. A filter screen is provided at the liquid outlet 10 to prevent the glass raw liquid from entering. The clarifying agent is introduced into the rotating pipe 9 through the clarifying agent inlet pipe 8, and then directly introduced into the inner side of the glass raw liquid through the liquid outlet 10. This allows the clarifying agent to release gas directly inside the glass raw liquid, so that the bubbles in the glass raw liquid absorb the gas, expand and float to the surface of the glass raw liquid and eventually break, thereby completing the removal of bubbles inside the glass raw liquid. In addition, this device is a sealed structure, which can prevent external impurities from contaminating the glass raw liquid and ensure the processing quality.
[0023] like Figure 2 and Figure 4 As shown: The lifting and stirring mechanism includes a stirring motor 11 fixed to the top of the outer tank 1. The main shaft of the stirring motor 11 passes through the inner liner 2 and is fixedly connected to an inner rotating rod 12. An outer cylinder 13 is sleeved on and slidably connected to the inner rotating rod 12. Guide slides 14 are fixedly connected to both sides of the inner rotating rod 12. Guide grooves 15 that slidably connect to the guide slides 14 are opened on both sides of the inner wall of the outer cylinder 13. A fixing rod 16 is fixedly connected to the inner top wall of the inner liner 2. A slider 17 is fixedly connected to the lower end of the fixing rod 16. A ring that slidably connects to the slider 17 is opened on the upper part of the outer side wall of the outer cylinder 13. The outer cylinder 13 has a spiral blade 19 fixedly connected to the outer wall of the inclined groove 18. When the stirring motor 11 is started, it can drive the inner rotating rod 12 to rotate, which in turn drives the spiral blade 19 on the outer cylinder 13 to rotate, thus stirring the glass raw liquid. At the same time, when the outer cylinder 13 rotates, the outer cylinder 13 moves up and down on the inner rotating rod 12 due to the sliding between the annular inclined groove 18 and the slider 17, and the sliding connection between the guide groove 15 and the guide slide 14. This allows the spiral blade 19 to rotate and move up and down simultaneously, thereby improving the stirring effect on the glass raw liquid and thus improving the debubbling effect.
[0024] like Figure 2 As shown: The top of the outer tank 1 is provided with a first through hole that communicates with the inner liner 2. The first through hole is rotatably connected to the main shaft end of the stirring motor 11 through a first bearing component, which facilitates the rotation of the main shaft end of the stirring motor 11.
[0025] like Figure 3 As shown: The rotating mechanism includes a drive motor 20 fixed to the upper side wall of the housing 7. The main shaft of the drive motor 20 passes through the housing 7 and is fixedly connected to a drive bevel gear 21. A driven bevel gear 22 that meshes with the drive bevel gear 21 is fixedly connected to the rotating tube 9. When the drive motor 20 is started, it can drive the drive bevel gear 21 to rotate. Since the drive bevel gear 21 and the driven bevel gear 22 mesh, the rotating tube 9 can be driven to rotate, which in turn drives the stirring teeth 24 to rotate, stirring the glass raw liquid. At the same time, the clarified liquid sprayed from the liquid outlet 10 is in more thorough contact with the glass raw liquid, improving the debubbling effect.
[0026] like Figure 3 As shown: The right side wall of the outer tank 1 is provided with a second through hole that communicates with the inner liner 2. The second through hole is rotatably connected to the outer side wall of the rotating tube 9 through a second bearing component, which facilitates the rotation of the rotating tube 9 and prevents leakage of the glass concentrate.
[0027] like Figure 2 As shown: An electromagnetic heating plate 23 is fixedly connected to the outer wall of the inner liner 2, which can continuously heat the glass liquid in the inner liner 2 to prevent it from cooling and condensing.
[0028] like Figure 2 As shown: The outer wall of the rotating tube 9 located in the inner liner 2 is fixedly connected with uniformly arranged stirring teeth 24, which can stir the glass raw liquid at the bottom of the inner liner 2.
[0029] Working principle: When using this device to degas the glass molten glass, the glass molten glass in the glass furnace is injected into the inner tank 2 through the feed valve 4. When the stirring motor 11 is started, it drives the inner rotating rod 12 to rotate, which in turn drives the spiral blades 19 on the outer cylinder 13 to rotate, thus stirring the glass molten glass. At the same time, when the outer cylinder 13 rotates, due to the sliding between the annular inclined groove 18 and the slider 17, and the sliding connection between the guide groove 15 and the guide slide bar 14, the outer cylinder 13 reciprocates up and down on the inner rotating rod 12, thereby realizing the rotation of the spiral blades 19. Simultaneously, the lifting and lowering displacement improves the stirring effect on the glass raw liquid, thereby improving the degassing effect. At the same time, the clarifying agent is introduced into the rotating tube 9 through the clarifying agent feed pipe 8, and then directly introduced into the inner side of the glass liquid through the liquid outlet 10, so that the clarifying agent can directly release gas inside the glass liquid, thereby causing the bubbles in the glass liquid to absorb the gas, expand and float to the surface of the glass liquid and finally break, thus completing the bubble removal work inside the glass liquid. Moreover, this device has a sealed structure, which can prevent external impurities from contaminating the glass raw liquid and ensure the processing quality.
[0030] At the same time, the drive motor 20 is started, which can drive the active bevel gear 21 to rotate. Since the active bevel gear 21 meshes with the driven bevel gear 22, it can drive the rotating tube 9 to rotate, which in turn drives the stirring teeth 24 to rotate, stirring the glass raw liquid. At the same time, it makes the clarified liquid sprayed from the liquid outlet 10 more fully contact the glass raw liquid, improving the debubbling effect.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
