[0001] This utility model relates to a stirrer, and more particularly to a glass liquid homogenizing stirrer applied in the field of glass manufacturing equipment technology. Background Technology

[0002] In the glass manufacturing process, the homogenization and stirring of molten glass is a crucial step that directly affects the quality of glass products. Currently, it is necessary to use a stirrer to uniformly mix the molten glass to achieve homogenization.

[0003] Chinese patent CN208260584U discloses a stirrer for improving the homogenization effect of liquid glass. This stirrer can efficiently homogenize liquid glass, improve the stirring efficiency of liquid glass, save production time, help improve glass quality, and save production costs.

[0004] Chinese patent CN212948549U discloses a fiberglass liquid mixer. This utility model, through the design of an internal cleaning structure, allows the device to easily perform high-pressure rinsing of the interior, ensuring the cleanliness of the inner wall and preventing the mixing of different types of fiberglass liquids. Furthermore, through the design of an exhaust replacement purification structure, the device can quickly treat odorous gases generated during the mixing of fiberglass liquids, preventing air pollution.

[0005] Existing agitators are inefficient, and the glass melt flows in a single pattern during the agitation process, resulting in insufficient mixing and uneven agitation. Utility Model Content

[0006] The technical problem to be solved by this utility model in view of the above-mentioned prior art is that the existing stirrers are inefficient and the glass liquid has a single flow pattern during the stirring process, resulting in insufficient mixing of the glass liquid and easy uneven stirring.

[0007] To address the aforementioned problems, this utility model provides a glass liquid homogenizing mixer, comprising a mixing tank with a feed inlet at the top, a first servo motor fixedly connected to the top of the mixing tank, a first rotating shaft extending into the mixing tank connected to the output end of the first servo motor, a second rotating shaft rotatably connected to the bottom of the mixing tank and located directly below the first rotating shaft, a first mixing paddle symmetrically and detachably connected to the side wall of the first rotating shaft, a second mixing paddle located inside the first mixing paddle symmetrically and detachably connected to the side wall of the second rotating shaft, the bottom of the first rotating shaft and the top of the second rotating shaft connected by an adapter, and a protective cover fitted over the adapter is installed between the first rotating shaft and the second rotating shaft, and an arc-shaped first scraper is fixedly connected to the bottom of the first mixing paddle, and the first scraper contacts the bottom of the mixing tank.

[0008] In the aforementioned stirrer, the first mixing blade on the first rotating shaft and the second mixing blade on the second rotating shaft are driven to rotate synchronously in opposite directions via an adapter, so as to fully mix the glass liquid and avoid uneven mixing.

[0009] As a further supplement to this application, the adapter includes a first bevel gear and a second bevel gear respectively sleeved on the bottom of the first rotating shaft and the top of the second rotating shaft. A third bevel gear is meshed between the first bevel gear and the second bevel gear. A third rotating shaft is rotatably connected inside the third bevel gear. A sleeve is sleeved on the surface of the first rotating shaft, the second rotating shaft and the third bevel gear. The sidewalls of the sleeves located on the first rotating shaft and the second rotating shaft are respectively connected to the sidewalls of the sleeves located on the third rotating shaft through connecting rods.

[0010] As a further supplement to this application, the side wall of the mixing tank is symmetrically and fixedly connected with support plates arranged vertically, and each set of support plates is rotatably connected with a lead screw.

[0011] As a further supplement to this application, a first strong magnetic block is sleeved on the surface of the lead screw and contacts the side wall of the mixing tank. A guide rail corresponding to the first strong magnetic block is symmetrically fixedly connected to the inner wall of the mixing tank. A second scraper is slidably connected to the guide rail through a second strong magnetic block, and the first strong magnetic block and the second strong magnetic block attract each other.

[0012] As a further addition to this application, the threaded portion of the lead screw is above the first mixing propeller, and the first strong magnetic block is fitted onto the surfaces of the first and second mixing propellers and in contact with them.

[0013] As a further supplement to this application, a controller is fixedly connected to the side of the mixing tank, a second servo motor is fixedly connected to the controller, and the output end of the second servo motor is connected to one of the lead screws. Both lead screws are fitted with belt pulleys, and the two belt pulleys are connected by a belt, which is located below the mixing tank.

[0014] As a further supplement to this application, the first and second rotating shafts are symmetrically provided with slots on their sidewalls, and the first and second mixing paddles respectively engage with the corresponding slots and are fixedly connected by bolts.

[0015] In summary, molten glass is fed into the mixing tank through the inlet. Then, the controller activates the first servo motor to drive the first rotating shaft, which in turn drives the first mixing paddle to rotate, thereby stirring and mixing the molten glass. At the same time, the first rotating shaft drives the second rotating shaft to rotate in the opposite direction via an adapter. A protective cover isolates the adapter from the molten glass to avoid affecting its service life. The second rotating shaft drives the second mixing paddle to rotate in the opposite direction to the first mixing paddle for stirring and mixing. At this time, the first and second mixing paddles rotate in opposite directions to stir the molten glass. This bidirectional stirring can prevent the formation of a unidirectional vortex in the molten glass, which would lead to insufficient mixing. During the stirring process of the first mixing paddle, the first scraper at the bottom rotates and scrapes against the inner wall of the mixing tank to prevent the liquid from settling at the bottom of the mixing tank.

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] First implementation method:

[0026] Figures 1-4 A glass liquid homogenizing mixer is shown, including a mixing tank 1 with a feed inlet at the top. A first servo motor 2 is fixedly connected to the top of the mixing tank 1. The output end of the first servo motor 2 is connected to a first rotating shaft 9 extending into the mixing tank 1. A second rotating shaft 12 located directly below the first rotating shaft 9 is rotatably connected to the bottom of the mixing tank 1. A first mixing paddle 10 is symmetrically and detachably connected to the side wall of the first rotating shaft 9. A second mixing paddle 13 located inside the first mixing paddle 10 is symmetrically and detachably connected to the side wall of the second rotating shaft 12. The bottom of the first rotating shaft 9 and the top of the second rotating shaft 12 are connected by an adapter. A protective cover 14 is installed between the first rotating shaft 9 and the second rotating shaft 12, which is fitted over the adapter. An arc-shaped first scraper 15 is fixedly connected to the bottom of the first mixing paddle 10, and the first scraper 15 contacts the bottom of the mixing tank 1.

[0027] The adapter includes a first bevel gear 18 and a second bevel gear 19 respectively sleeved on the bottom of the first rotating shaft 9 and the top of the second rotating shaft 12. A third bevel gear 20 is meshed between the first bevel gear 18 and the second bevel gear 19. A third rotating shaft 22 is rotatably connected inside the third bevel gear 20. A sleeve 25 is sleeved on the surface of the first rotating shaft 9, the second rotating shaft 12 and the third bevel gear 20. The side walls of the sleeve 25 on the first rotating shaft 9 and the second rotating shaft 12 are respectively connected to the side walls of the sleeve 25 on the third rotating shaft 22 through connecting rods 21.

[0028] Working principle: Liquid glass is fed into the mixing tank 1 through the inlet. Then, the controller 3 turns on the first servo motor 2 to drive the first rotating shaft 9 to rotate the first mixing paddle 10, thereby stirring and mixing the liquid glass. At the same time, the first rotating shaft 9 drives the second rotating shaft 12 to rotate in the opposite direction through the adapter. The protective cover 14 isolates the adapter from the liquid glass to avoid affecting its service life. The second rotating shaft 12 drives the second mixing paddle 13 to rotate in the opposite direction to the first mixing paddle 10 for stirring and mixing. At this time, the first mixing paddle 10 and the second mixing paddle 13 rotate in opposite directions to stir the liquid glass. The bidirectional stirring can avoid the formation of a unidirectional vortex in the liquid glass, which would lead to insufficient mixing of the liquid glass. During the stirring process of the first mixing paddle 10, the first scraper 15 at the bottom rotates and scrapes the inner wall of the mixing tank 1 to prevent the liquid from settling at the bottom of the mixing tank 1.

[0029] This invention uses an adapter to drive the first mixing paddle 10 on the first rotating shaft 9 and the second mixing paddle 13 on the second rotating shaft 12 to rotate synchronously in opposite directions, thereby fully mixing the molten glass and avoiding uneven mixing.

[0030] Second implementation method:

[0031] Figures 2-3 and Figures 5-6The mixing tank 1 is shown to have symmetrically fixed support plates 5 arranged vertically on its side wall. Each set of support plates 5 is rotatably connected to a lead screw 6. A first strong magnetic block 11 is fitted on the surface of the lead screw 6 and contacts the side wall of the mixing tank 1. A guide rail 17 corresponding to the first strong magnetic block 11 is symmetrically fixed to the inner wall of the mixing tank 1. A second scraper 16 is slidably connected to the guide rail 17 through a second strong magnetic block. The first strong magnetic block 11 and the second strong magnetic block attract each other. The threaded part of the lead screw 6 is higher than the first mixing paddle 10, and the first strong magnetic block 11 is fitted onto the first mixing paddle 10 and the second mixing paddle 16. The surface of the paddle 13 is in contact with it. A controller 3 is fixedly connected to the side of the mixing tank 1. A second servo motor 4 is fixedly connected to the controller 3. The output end of the second servo motor 4 is connected to one of the lead screws 6. Both lead screws 6 are fitted with belt pulleys 7. The two belt pulleys 7 are connected by a belt 8. The belt 8 is located below the mixing tank 1. The side walls of the first rotating shaft 9 and the second rotating shaft 12 are symmetrically provided with slots 23. The first mixing paddle 10 and the second mixing paddle 13 are respectively engaged with the corresponding slots 23 and fixedly connected by bolts 24.

[0032] Working principle: The controller 3 controls the first mixing paddle 10 and the second mixing paddle 13 to mix and stir at regular intervals. After every 3 stirring cycles, the scraper cleaning program is automatically started, and the first servo motor 2 is disconnected to stop stirring. At this time, the first mixing paddle 10 and the second mixing paddle 13 are located directly below the second scraper 16. The controller 3 turns on the second servo motor 4 to drive one of the lead screws 6 to rotate, and drives the two lead screws 6 to rotate synchronously through the belt pulley 7 and the belt 8, so that the two first strong magnetic blocks 11 move up and down synchronously. The movement of the first strong magnetic blocks 11 drives the second scraper 16 on the second strong magnetic block in the mixing tank 1 to move up and down, thereby cleaning the liquid adhering to the surface of the first mixing paddle 10 and the second mixing paddle 13, avoiding the long-term adhesion of glass liquid to the surface and affecting the mixing effect. When it is necessary to disassemble and clean the first mixing paddle 10 and the second mixing paddle 13, the bolt 24 can be turned to pull it out from the sleeve 25.

[0033] This invention, by setting a second scraper 16 that moves up and down in a circular motion, can periodically clean the liquid adhering to the surfaces of the first mixing paddle 10 and the second mixing paddle 13, thus avoiding affecting the mixing effect of the molten glass.

[0034] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
