Description

Technical Field

[0001] This invention belongs to the field of glass raw material stirring technology, specifically a planetary stirring device with rotatable parallelogram blades. Background Technology

[0002] A mixing device is a general-purpose mechanical equipment that uses power to drive mixing elements, such as blades, paddles, and spirals, to make mechanical movements in a container, causing two or more materials to undergo physical mixing, chemical reaction, or heat and mass transfer, ultimately achieving uniform material distribution, system stability, or process objectives. It is widely used in industrial and consumer sectors such as chemical, food, building materials, pharmaceutical, metallurgy, and environmental protection.

[0003] Glass raw materials refer to various basic materials that are mixed according to a specific formula ratio and processed into glass products through high-temperature melting, forming, annealing and other processes. They are mainly divided into three categories: main materials, auxiliary materials and auxiliary raw materials. In some scenarios, recycled materials are added to reduce energy consumption. All raw materials must meet the requirements of low impurities, stable composition and suitable particle size to avoid affecting the quality of finished glass products.

[0004] Planetary mixing devices for glass materials are designed for mixing various glass raw materials with different functions, such as quartz sand, soda ash, and feldspar, according to the formulation requirements of glass products. The planetary mixing device is used to uniformly mix these materials together to form a mixture with consistent composition, without agglomeration or stratification. It is the core equipment for mixing raw materials in the front-end of glass production.

[0005] In current technology, parallelogram blades are usually used to agitate materials while remaining stationary relative to the mixing shaft. Since the parallelogram blades experience wear during contact with the materials, they need to be replaced when worn to a certain extent. However, the design of the parallelogram blades often means that only one side is in constant high-speed contact with the materials to achieve the agitation effect, while the other side does not collide with the materials at high speed. This results in one side of the parallelogram blade being excessively worn while the other side is less worn. Replacing a parallelogram blade with only one side showing significant wear would increase costs for the company.

[0006] Therefore, the present invention provides a planetary stirring device with rotatable parallelogram blades. Summary of the Invention

[0013] Preferably, the pushing component includes two toothed discs, which are symmetrically arranged on the inner wall of the stirring cylinder, and the outer walls of the two toothed discs are rotatably connected to the inner wall of the rotating cylinder.

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 12 As shown in the embodiment of the present invention, a planetary mixing device with rotatable parallelogram blades includes a mixing drum 1, which is cylindrical. Inside the mixing drum 1 are two rotating drums 5 arranged in a symmetrical annular array. Multiple parallelogram blades 501 are evenly and symmetrically distributed around the central axis on the outside of the two rotating drums 5. These multiple parallelogram blades 501 are used to mix the material inside the mixing drum 1. When the quadrilateral blades 501 rotate and mix inside the mixing drum 1, their specific side lengths allow for a larger sweeping area during mixing, thus improving the mixing performance. The material undergoes continuous shearing and circumferential convection agitation, which facilitates the agitation of the material in the mixing drum 1. The top of the mixing drum 1 is provided with multiple feeding pipes 3, which are used to feed the raw material into the mixing drum 1. The top of the two rotating drums 5 is provided with a ring stirring assembly, which includes a connecting rod 701. The ring stirring assembly is used to drive the quadrilateral blades 501 on the two rotating drums 5 to agitate the glass raw material in the mixing drum 1 through the connecting rod 701. The interior of the two rotating drums 5 is provided with a flipping assembly, which can drive the quadrilateral blades 501 to rotate and adjust the angle of the quadrilateral blades. Before use, the feeding pipe 3 is connected to the conveying pipe for transporting and mixing materials using a flange. When it is necessary to mix the glass raw materials, the dispersing assembly is driven to intermittently disperse the material in the feeding pipe 3 into the mixing drum 1. At the same time, the ring stirring assembly is driven to drive multiple connecting rods 701 to drive two rotating drums 5 to move around in the mixing drum 1. The quadrilateral blades 501 on the two rotating drums 5 will agitate the material put into the mixing drum 1, thereby realizing the mixing operation of the glass material in the mixing drum 1. When one side of the quadrilateral blade 501 is worn to a certain extent and can no longer evenly mix the material, the tilting assembly is driven to operate. The tilting assembly will then... The quadrilateral blades 501 are rotated, allowing for angle changes and replacement. The ring stirring assembly continuously stirs the material using the quadrilateral blades 501. Furthermore, the tilting assembly allows for adjustment of the blade angle when one side of the quadrilateral blade 501 becomes worn due to stirring, reducing its effectiveness. This ensures that the unworn portion of the blade contacts the glass material, effectively improving blade utilization and extending its lifespan. It also prevents difficulties in blade replacement due to material accumulation in the mixing drum 1 during stirring, resulting in better material mixing and facilitating the mixing of glass materials.

[0025] In the above embodiments, a stirring cycle can be preset. When the preset cycle is reached, the flipping component drives the quadrilateral blade 501 to rotate and adjust the angle of the quadrilateral blade 501. The preset cycle can be adjusted based on the hardness of the material and past work experience. Alternatively, the flipping component can be manually triggered to drive the quadrilateral blade 501 to rotate based on the experience of the staff.

[0026] like Figures 3 to 4 As shown, the ring stirring assembly also includes a rotating disk 201. The outer wall of the rotating disk 201 is rotatably connected to the inner wall of the stirring drum 1. A stirring motor 2 is fixedly installed on the top of the stirring drum 1. The output end of the stirring motor 2 passes through the inner wall of the stirring drum 1 and is fixedly connected to the top of the rotating disk 201. A circular plate 702 is fixedly installed on the top of each of the multiple connecting rods 701. The outer walls of the multiple connecting rods 701 are placed inside the rotating disk 201. The bottom ends of the multiple connecting rods 701 are fixedly connected to the tops of the two rotating drums 5 respectively. When it is necessary to drive the rotating drum 5 to rotate inside the mixing drum 1, the stirring motor 2 is driven to operate. The stirring motor 2 will drive the rotating disk 201 to rotate. When the rotating disk 201 rotates, the rotating disk 201 will rotate together with the connecting rod 701 through its own rotation and the limiting pull of the top of the connecting rod 701 by the circular plate 702. The connecting rod 701 will then drive the rotating drum 5 to rotate inside the mixing drum 1 through the rotation of the rotating disk 201. The rotating drum 5 will then drive the quadrilateral blades 501 to rotate in a ring inside the mixing drum 1, thereby enabling the rotating drum 5 to drive the quadrilateral blades 501 to perform a circumferential stirring operation on the material inside the mixing drum 1, thus achieving the function of driving the quadrilateral blades 501 to rotate and stir inside the mixing drum 1.

[0027] like Figures 3 to 5 As shown, gear shafts 7 are fixedly installed on the outer walls of multiple connecting rods 701, a fixed disk 601 is fixedly installed on the inner wall of the stirring cylinder 1, and a gear ring 6 is fixedly installed on the outer wall of the fixed disk 601. The teeth on the multiple gear shafts 7 can mesh with the teeth on the gear ring 6. The outer wall of the connecting rods 701 can be rotatably connected to the inner wall of the rotating disk 201. An isolation disk 703 is slidably connected to the inner wall of the stirring cylinder 1. The outer walls of the multiple connecting rods 701 all penetrate the inner wall of the isolation disk 703 and are slidably connected to the inner wall of the isolation disk 703. A sealing mechanism is provided between the isolation disk 703 and the stirring cylinder 1. The sealing mechanism includes a sealing seat, a rotary seal, a clamping ring, a dust cover, and a circular sealing ring. The sealing seat is fixed to the inner wall of the stirring cylinder 1. The rotary seal is located between the isolation disk 703 and the sealing seat. The clamping ring axially positions the rotary seal. The circular sealing ring achieves static sealing between the sealing seat and the stirring cylinder 1. The dust cover is located on the outside of the sealing mechanism. When the rotating disk 201 drives the rotating drum 5 to rotate inside the mixing drum 1 via the connecting rod 701, a sealing mechanism is set between the isolation disk 703 and the mixing drum 1. When the connecting rod 701 drives the isolation disk 703 to rotate at the top of the mixing drum 1, the connecting rod 701 drives the gear shaft 7 to rotate together with the rotation direction of the isolation disk 703. The sealing mechanism between the two will seal and block the mixing drum 1 and the isolation disk 703. The sealing seat is fixedly installed on the inner wall of the mixing drum 1. The rotating seal is set between the isolation disk 703 and the sealing seat, thereby realizing dynamic sealing during the rotation of the isolation disk 703. The clamping ring abuts against the outer side of the rotating seal and axially clamps and positions the rotating seal, keeping the rotating seal in a stable sealing state and preventing axial movement or seal failure. The circular sealing ring is set between the mating surface of the sealing seat and the mixing drum 1 to achieve static sealing between the sealing seat and the mixing drum 1, preventing material leakage from the assembly gap. The dust cover is set on the outside of the sealing mechanism. To prevent dust and material impurities from entering the sealed area, ensuring the long-term stable operation of the sealing mechanism, and improving the overall sealing performance and service life of the equipment, the sealing mechanism is designed to prevent glass raw material dust from entering the upper space of the mixing drum 1 through the sliding gap. This prevents floating glass raw material dust from contaminating the bearings and gear mechanism, causing mechanical jamming. When the gear shaft 7 moves, it will rotate by meshing with the teeth on the outside of the gear ring 6. As the rotating drum 5 rotates around inside the mixing drum 1, the gear shaft 7 drives the rotating drum 5 to rotate inside the mixing drum 1 through the connecting rod 701. The rotating drum 5 then drives the quadrilateral blades 501 to stir and mix the material inside the mixing drum 1. This serves to stir the material by rotating the drum 5 and driving the quadrilateral blades 501. It should be noted that the sealing mechanism includes a sealing ring and a positioning and guiding structure, which are used to seal and isolate the inside of the mixing drum 1 when the connecting rod 701 drives the rotating drum 5 to rotate inside the mixing drum 1. This is existing technology and is only described in this solution.

[0028] like Figures 4 to 6 As shown, the outer walls of both rotating drums 5 are provided with multiple scraper rods 901, and the multiple scraper rods 901 correspond one-to-one with multiple quadrilateral blades 501. The ends of the multiple quadrilateral blades 501 away from the rotating drum 5 are rotatably connected to the inside of the scraper rods 901. The outer side of the scraper rods 901 is provided with scraping blades, and the scraping blades face the same direction as the rotation of the rotating drum 5. The inner wall of the mixing drum 1 is fixedly installed with a positioning shaft 8. The scraping mouths of multiple support rods 9 can contact the outer wall of the positioning shaft 8 and the inner wall of the mixing drum 1. The scraper rods 901 are used to scrape the material on the inner wall of the mixing drum 1 and the outer wall of the positioning shaft 8. For details, please refer to the appendix. Figure 5As shown, the upper and lower ends of the multiple scraper rods 901 are fixedly connected to support rods 9, and the ends of the support rods 9 away from the scraper rods 901 are respectively fixedly connected to the top and bottom surfaces of the rotating drum 5. It is understood that this arrangement is only one embodiment proposed by the present invention. In specific implementation, the connection method can be designed according to the requirements.

[0029] When the rotating drum 5 drives the quadrilateral blades 501 to rotate, the rotating drum 5 will drive the support rod 9 to rotate together inside the mixing drum 1. The support rod 9 will then drive the scraper 901 to rotate together. The scraper 901 will scrape the material inside the mixing drum 1 by rotating, thereby scraping up the material piled at the bottom of the mixing drum 1 and adhering to the inner wall of the mixing drum 1, preventing the material from adhering to both and affecting the uniform mixing operation. The scraper 901 also plays a certain role in mixing when rotating. At the same time, the scraper 901 supports the multiple quadrilateral blades 501, preventing the quadrilateral blades 501 from being damaged by excessive force during the mixing process due to having only a single connecting shaft, thus improving its stability during operation. It can be understood that in actual use, in order to improve the mixing effect, the mixing rate is constantly changed, thereby effectively avoiding the situation where the scraping range of the scraper 901 remains unchanged when the mixing speed is constant.

[0030] like Figures 6 to 8 As shown, the flipping assembly includes multiple rotating shafts 505. One end of each rotating shaft 505 is fixedly connected to the outer wall of multiple quadrilateral blades 501. The outer walls of the multiple rotating shafts 505 are rotatably connected to the inner wall of the rotating cylinder 5 and the inner walls of the three scrapers. A gear 504 is fixedly installed at one end of each rotating shaft 505. The multiple quadrilateral blades 501 are arranged in a symmetrical array outside the rotating cylinder 5. A pushing assembly is provided inside the rotating cylinder 5. The pushing assembly is used to drive the quadrilateral blades 501 to rotate and flip inside the stirring cylinder 1 through the gear 504. When the gear shaft 7 drives the rotating drum 5 to rotate inside the mixing drum 1 via the connecting rod 701, the pushing component inside the rotating drum 5 is driven to operate. The pushing component will push multiple gears 504 inside the rotating drum 5 to rotate. The multiple gears 504 will then drive the quadrilateral blades 501 to automatically rotate outside the rotating drum 5 via multiple rotating shafts 505. This allows the quadrilateral blades 501 to automatically rotate outside the rotating drum 5 to replace the rotating surface when one side of the mixing surface of the quadrilateral blades 501 is severely worn. This allows the quadrilateral blades 501 to be reused, effectively improving the utilization rate and lifespan of the blades. It should be noted that the maximum rotation angle of the gears 504 when pushed by the pushing component is 180 degrees, that is, the maximum rotation angle of the quadrilateral blades 501 is 180 degrees. The quadrilateral blades 501 rotate gradually from small to large angles, and the initial placement angle of the quadrilateral blades 501 needs to be set according to the actual working scenario.

[0031] like Figures 6 to 8 As shown, the pushing assembly includes a toothed disc 502, the outer wall of which is rotatably connected to the inner wall of the rotating cylinder 5, the teeth on the toothed disc 502 can mesh with the teeth on multiple gears 504, a connecting frame 503 is fixedly installed on the inner wall of the toothed disc 502, and multiple retaining rods 506 are fixedly installed on the inner wall of the rotating cylinder 5, one end of each retaining rod 506 is rotatably connected to the inner wall of the multiple gears 504 respectively. When it is necessary to drive the gear 504 to rotate, the connecting frame 503 is driven to rotate inside the rotating drum 5. The connecting frame 503 will then drive the gear disk 502 to rotate inside the rotating drum 5. When the gear disk 502 rotates, it will drive multiple gears 504 to rotate through tooth meshing. The multiple gears 504 will then rotate on the retaining rod 506, thereby causing the gears 504 to drive the quadrilateral blades 501 to rotate outside the rotating drum 5, thus driving the gears 504 to drive the quadrilateral blades 501 to rotate.

[0032] like Figures 6 to 8 As shown, a drive wheel motor 10 is fixedly installed on the top of the circular plate 702. A shaft 1001 is fixedly installed at the output end of the drive wheel motor 10. The bottom end of the shaft 1001 is rotatably connected to the inner wall of the rotating drum 5. The inner wall of the connecting frame 503 is fixedly connected to the outer wall of the shaft 1001. The outer wall of the shaft 1001 can be rotatably connected to the inner walls of the connecting rod 701, the circular plate 702, and the gear shaft 7. In specific implementation, to facilitate power supply to the drive wheel motor 10, on the one hand, corresponding wire holes can be opened on the shell surface of the mixing drum 1 according to the actual factory site, and then an external power supply can be connected. On the other hand, since the drive wheel motor 10 only works when the angle of the quadrilateral blades 501 needs to be adjusted, and does not need to work continuously, it can also be... The portable power supply powers the drive wheel motor 10, and only periodic maintenance of the power supply is required.

[0033] When the gear disc 502 needs to be rotated, the drive wheel motor 10 rotates inside the rotating drum 5. The drive wheel motor 10 then drives the shaft 1001 to rotate inside the rotating drum 5. The shaft 1001 then drives the connecting frame 503 to rotate, thereby causing the connecting frame 503 to drive the two gears 504 to rotate inside the rotating drum 5. The gears 504 then drive the quadrilateral blades 501 to rotate through tooth meshing, providing power for the rotation of the quadrilateral blades 501. It can be understood that by driving the drive wheel motor 10 to drive the quadrilateral blades 501 to rotate, multi-angle rotation of the quadrilateral blades 501 can be achieved. That is, in specific use, the angle of the quadrilateral blades 501 can be adjusted according to different raw materials to achieve different stirring effects. This not only achieves the effect of switching the wear surface of the quadrilateral blades 501, but also achieves the effect of multiple stirring modes.

[0034] like Figures 9 to 12 As shown, multiple discharge pipes 401 are fixedly installed at the bottom of the mixing drum 1. A conveying pump 4 is fixedly installed on the outside of each discharge pipe 401. The conveying pump 4 is used to discharge the raw material being mixed in the mixing drum 1. A material dispersing assembly is provided inside each of the multiple feeding pipes 3. The material dispersing assembly is used to drive the glass raw material in the feeding pipe 3 to be intermittently dispersed and fed. The material dispersing assembly includes two baffles 303. Both baffles 303 are placed inside the feeding pipe 3 and are stacked. The baffle 303 located above is fixedly connected to the inner wall of the feeding pipe 3. The top of the baffle 303 located below can be rotatably connected to the bottom of the baffle 303 located above. The inner wall of each baffle 303 is provided with a drop port 304. Both drop ports 304 are rectangular and are used to allow the material in the feeding pipe 3 to slide into the mixing drum 1. When the rotating drum 5 drives the quadrilateral blades 501 to rotate inside the mixing drum 1 to stir the material, it pushes the lower baffle plate 303 inside the feeding pipe 3 to rotate. When the lower baffle plate 303 rotates to coincide with the upper baffle plate 303, the discharge port 304 between the two baffle plates 303 will be in a through state, and the material in the feeding pipe 3 will flow into the mixing drum 1 through the discharge port 304 and the two baffle plates 303. When the lower baffle plate 303 is pushed to rotate to an alternating state with the upper baffle plate 303, the two discharge ports 304 will be in an alternating closed state, and the material in the feeding pipe 3 will stop flowing into the mixing drum 1. By setting multiple feeding pipes 3, the material can be controlled to be intermittently dispersed into the mixing drum 1, avoiding the phenomenon of material piling up when it is fed.

[0035] like Figures 10 to 11 As shown, the inner wall of the mixing drum 1 is symmetrically fixed with retaining plates 302. One end of each retaining plate 302 is fixedly connected to the outer wall of the feeding pipe 3. The inner wall of the feeding pipe 3 is rotatably connected with a toothed tube 301. The inner wall of the toothed tube 301 is fixedly connected to the outer wall of the baffle plate 303 located below. The teeth on the toothed tube 301 can mesh with the teeth on multiple toothed shafts 7. When the rotating disk 201 drives the gear shaft 7 to rotate on the gear ring 6 via the connecting rod 701, the continuous rotation of the gear shaft 7 causes it to move to one side of the feeding pipe 3. At this point, the gear shaft 7 will then drive the toothed tube 301 on the feeding pipe 3 to rotate through tooth meshing. It should be noted that when the gear shaft 7 and the toothed tube 301 initially contact and then separate, the gear shaft 7 has rotated one revolution, and the toothed tube 301 has rotated one-third of a revolution. That is, the number of teeth on the toothed tube 301 is the sum of the number of teeth on the three gear shafts 7. Initially... In this state, the two baffles 303 are in an alternating closed state. When the gear shaft 7 contacts the gear tube 301, the gear tube 301 will rotate between the two retaining plates 302. When the gear tube 301 rotates, it will drive the lower baffle 303 to rotate in the feeding pipe 3, causing the lower baffle 303 to rotate in the feeding pipe 3. After rotating one-third of a turn, the gear shaft 7 and the gear tube 301 separate, and the two discharge ports 304 will overlap and open. See the attached diagram for details. Figure 11 As shown, the material in the feeding pipe 3 will flow into the mixing drum 1. After the gear shaft 7 rotates one-third of a turn around the gear ring 6, the gear shaft 7 will mesh with the gear tube 301 again. The difference is that at this time, when the baffle plate 303 is in place, the two discharge ports 304 will be staggered, thereby blocking the material. It can be seen that the two discharge ports 304 will overlap once for every turn of the gear shaft 7 around the gear ring 6, and the overlap time is the time it takes for the gear shaft 7 to rotate one-third of a turn around the gear ring 6. It should be noted that since the number of teeth of the gear ring 6, gear shaft 7 and gear tube 301 are all fixed, the installation position of the gear tube 301 needs to be considered during installation to ensure that the gear tube 301 can mesh with the gear shaft 7 during the rotation of the gear shaft 7 around the gear ring 6.

[0036] like Figures 11 to 12 As shown, two sets of limiting rods 307 are slidably connected to the inner walls of the two fixed plates 302. One end of each set of limiting rods 307 is fixedly installed with a locking block 305. One end of each locking block 305 can engage with the tooth groove of the toothed tube 301. Two sets of return springs 306 are provided between one side of each locking block 305 and the outer wall of each of the two fixed plates 302. The two sets of return springs 306 are respectively placed outside the two sets of limiting rods 307. When the gear shaft 7 drives the gear tube 301 to rotate, the gear tube 301 will push the locking block 305 to move on the outer wall of the feeding tube 3. The locking block 305 will then slide on the fixed plate 302 by pressing the return spring 306 through the limiting rod 307. When the gear shaft 7 separates from the gear tube 301 and stops pushing the gear tube 301, the return spring 306 will push the locking block 305 to reset through elasticity. The locking block 305 will lock the tooth groove in the gear tube 301, thereby limiting the operation of the gear tube 301 and preventing the gear tube 301 from running and rotating when it is not pushed by the gear shaft 7, which would affect the uniform feeding of materials in the gear tube 301 and play the role of limiting the gear tube 301.
