Description

Technical Field

[0001] This invention relates to the field of mixing equipment technology, specifically to a uniform mixing equipment for green tire silica slurry. Background Technology

[0002] As the global automotive industry accelerates its transformation towards energy conservation and environmental protection, green tires, with their core advantages such as low rolling resistance, high wear resistance, and excellent wet grip, have become the mainstream development trend in the tire industry. Silica, as a key reinforcing filler in the green tire production process, directly determines the tire's mechanical properties, anti-aging performance, and energy-saving and environmental protection effects through its uniform dispersion in the rubber matrix. In the green tire production process, silica needs to be mixed with various components such as rubber latex, softeners, and antioxidants to form a slurry. The uniformity of the slurry mixing is a core prerequisite for ensuring the quality stability of subsequent mixing and molding processes. Therefore, silica slurry uniform mixing equipment occupies an indispensable and important position in the green tire production process.

[0003] Chinese patent CN119793272A discloses a slurry mixing device for glutinous rice flour processing, which can achieve the effect of fully mixing multiple raw materials, but cannot achieve the effect of pre-treating raw materials and uniformly distributing them, which may lead to uneven mixing of the final product due to local accumulation.

[0005] Preferably, the pretreatment device includes a pretreatment box, with a feed nozzle connected to the top of the pretreatment box. Arc-shaped screen plates are fixedly connected to both sides of the inner wall of the pretreatment box, and first screen holes are evenly distributed on the arc-shaped screen plates. Rotating shafts are rotatably connected to the portions of both sides of the inner wall of the pretreatment box above the arc-shaped screen plates.

[0006] Preferably, the shaking mechanism includes a fixed plate, a shaking spring fixedly connected to the top of the fixed plate, a shaking screen plate fixedly connected to the top of the shaking spring, a second screen hole evenly opened on the top of the shaking screen plate, a lifting rod fixedly connected to the bottom of the shaking screen plate, two sets of the fixed plate symmetrically distributed on both sides of the inner wall of the feed nozzle, the bottom of the lifting rod slidingly connected to the side of the cam, the diameter of the second screen hole is larger than the diameter of the first screen hole, the silica powder is poured into the feed nozzle, the first motor is started to drive the rotating shaft to rotate, synchronously driving the cam and the crushing teeth to rotate, the cam rotates The lifting rod moves up and down reciprocally, which in turn drives the vibrating screen plate to vibrate back and forth, causing the powder in the feed nozzle to undergo preliminary uniform screening through the second screening hole. After screening, the powder falls into the pretreatment box, where the crushing teeth further crush the falling powder, breaking up any clumps. The crushed powder then undergoes a second fine screening through the first screen hole on the arc-shaped screen plate to ensure uniform particle size. Qualified powder falls to the bottom of the pretreatment box and enters the feed pipe through the second solenoid valve to complete the pretreatment. The reciprocating motion of the vibrating screen plate ensures that the powder falls evenly onto the crushing teeth, preventing accumulation and ensuring uniform crushing.

[0007] Preferably, the feeding pipe includes a pipe body, a second motor is fixedly connected to one side of the pipe body, the drive shaft of the second motor passes through the pipe body and is fixedly connected to a driving bevel gear, a driven bevel gear meshes with the side of the driving bevel gear, a first rotating rod is fixedly connected to the bottom of the driven bevel gear, a rotating sleeve is sleeved on and rotatably connected to the first rotating rod, the rotating sleeve is fixedly connected to the inner wall of the pipe body through a bracket, a spiral conveying blade is sleeved on and fixedly connected to the portion of the first rotating rod below the rotating sleeve, a second rotating rod is fixedly connected to the bottom of the first rotating rod, and scrapers are evenly fixedly connected to the bottom side of the second rotating rod. The feeding mechanism includes a feeding box, and the bottom of the inner wall of the feeding box is evenly... A discharge hole is provided, and the discharge box is fixedly connected to the top of the inner wall of the mixing tank. The top of the pipe body is connected to the discharge port of the second solenoid valve. The pipe body passes through the mixing tank and is connected to the top of the discharge box. The second rotating rod extends into the interior of the discharge box. The bottom of the scraper is in contact with the bottom of the inner wall of the discharge box. The pretreated silica enters the pipe body through the second solenoid valve. The second motor is started to drive the active bevel gear and the driven bevel gear to mesh and drive the first rotating rod and the spiral conveyor blade to rotate, so as to stably convey the powder downward to the discharge box. At the same time, the first rotating rod drives the second rotating rod and the scraper to rotate. The scraper scrapes against the bottom of the inner wall of the discharge box to prevent the powder from accumulating and blocking the discharge hole, so that the powder falls evenly from the discharge hole into the mixing tank.

[0008] Preferably, the stirring device includes a hollow rotating tube. The bottom side of the hollow rotating tube is fitted with and fixedly connected to the output end of a belt drive mechanism. The input end of the belt drive mechanism is fixedly connected to the drive shaft of a third motor. Two sets of arc-shaped stirring plates are uniformly fixedly connected to the side of the hollow rotating tube, symmetrically arranged on the hollow rotating tube. S-shaped stirring plates are uniformly fixedly connected to the portion of the hollow rotating tube between the two sets of arc-shaped stirring plates. Shearing holes are uniformly formed on the side of the S-shaped stirring plates. L-shaped cleaning scrapers are uniformly fixedly connected to the side of the hollow rotating tube. The hollow rotating tube penetrates the bottom of the inner wall of the stirring tank and connects with… The first connecting pipe is connected, and the hollow rotating pipe is rotatably connected to the first connecting pipe. The third motor is fixedly connected to the bottom of the mixing tank through a bracket. The side of the hollow rotating pipe is evenly provided with feeding ports. The inner wall of the feeding port is fixedly connected with a dispersing plate. The side of the dispersing plate is evenly provided with dispersing holes. When the third motor is started, the hollow rotating pipe is driven to rotate through the belt drive mechanism, which drives the arc-shaped stirring plate, the S-shaped stirring plate and the L-shaped cleaning scraper to rotate synchronously. The arc-shaped stirring plate rolls the slurry into the middle to achieve large-area mixing. The S-shaped stirring plate shears and refines the slurry through the shearing holes to enhance the mixing uniformity. The L-shaped cleaning scraper scrapes against the inner wall of the mixing tank to remove the slurry adhering to the tank wall.

[0009] Preferably, the feeding mechanism includes a second connecting pipe, with a mixing auger fixedly connected to the inner wall of the second connecting pipe. An additive feeding pipe and a latex feeding pipe are respectively connected to both sides of the second connecting pipe. The end of the second connecting pipe away from the additive feeding pipe is connected to the inlet of the conveying pump. When the silica is fed, the conveying pump is started, and the additive and latex enter the second connecting pipe through their respective feeding pipes. Under the negative pressure of the conveying pump, they are forcibly premixed by the mixing auger. The premixed mixture is sprayed out through the feeding port on the hollow rotating pipe, and after impacting the dispersing plate, it is dispersed into fine droplets through the dispersing holes, which are fully mixed with the falling silica powder.

[0010] This invention provides a uniform mixing device for green tire silica slurry. It has the following beneficial effects: 1. This green tire silica slurry uniform mixing equipment achieves efficient and precise pretreatment of silica powder through a synergistic design of shaking screening, double crushing, and fine screening. Driven by the first motor, the cam-linked lifting rod drives the shaking screen plate to reciprocate up and down, so that the silica powder in the feed nozzle is initially uniformly screened to avoid powder accumulation. At the same time, the screened powder falls evenly onto the crushing teeth, ensuring uniform contact of the powder during crushing and improving the crushing effect. Subsequently, the crushing teeth further refine and crush the agglomerated powder, effectively solving the problem of silica agglomeration caused by moisture during storage. Finally, it is finely screened by the arc-shaped screen plate. Multiple treatments ensure the uniformity of the qualified powder particle size and completely avoid agglomeration affecting the subsequent mixing effect. In addition, the linkage design of the shaking mechanism and the crushing teeth enables the pretreatment process to be completed continuously and automatically without manual intervention, improving the pretreatment efficiency and laying the foundation for the thorough mixing of silica with other materials, thereby improving the quality and stability of the final slurry product.

[0011] 2. This green tire silica slurry uniform mixing equipment achieves stable feeding of pretreated silica through a screw conveyor and scraper unblocking, solving the problems of jamming, accumulation, and uneven feeding in traditional powder conveying. The second motor drives the screw conveyor blades to rotate, smoothly conveying the powder in the tube downwards, avoiding material interruption or congestion caused by the powder falling under its own weight. At the same time, the first rotating rod is linked to the second rotating rod to drive the scraper to rotate at the bottom of the feeding box, which can scrape off the attached powder in real time, preventing the feeding hole from being blocked, and ensuring that the powder falls evenly into the mixing tank from the feeding hole. Stable and uniform feeding avoids the problem of excessive local powder during subsequent mixing, which leads to insufficient mixing, and provides a guarantee for the mixing of silica with additives and latex.

[0012] 3. This green tire silica slurry uniform mixing equipment uses a third motor to drive an arc-shaped mixing plate, an S-shaped mixing plate, and an L-shaped cleaning scraper to construct a three-dimensional mixing system, achieving deep mixing of the silica slurry. The arc-shaped mixing plate rotates, forming an outer entrapment that gathers the slurry near the tank wall towards the center, increasing the contact area between the raw materials. The S-shaped mixing plate rotates synchronously, and its side shear holes can perform high-frequency shearing to refine the slurry, breaking up powder agglomerates and ensuring thorough mixing of silica with other raw materials, improving mixing uniformity. The L-shaped cleaning scraper rotates close to the inner wall of the mixing tank, scraping away slurry adhering to the tank wall in real time, avoiding material accumulation and waste, and preventing the accumulation from drying and becoming difficult to clean. Multi-layered mixing improves the mixing effect, ensuring stable final slurry quality and avoiding poor product quality due to uneven mixing.

[0013] 4. This green tire silica slurry uniform mixing equipment features a dual design of premixing additives and latex, and refining by a dispersing plate. This enhances the mixing effect of the three raw materials. Before entering the mixing tank, the additives and latex are forcibly premixed by a mixing auger driven by a delivery pump. This avoids the problem of excessively high or low local concentrations of additives caused by traditional direct feeding, laying the foundation for subsequent mixing with silica. The premixed mixture is sprayed out from the feeding port and impacts the dispersing plate at high speed. It is refined into tiny droplets through the evenly distributed dispersing holes on the side of the dispersing plate, increasing the contact area between the droplets and the silica powder. This allows the droplets to quickly penetrate into the gaps between the powder and avoid the problem of insufficient mixing caused by the powder encapsulating the liquid. This ensures that the silica, additives, and latex are fully integrated, improving the final product quality. Attached Figure Description

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] For the first embodiment, please refer to... Figures 1-5This invention provides a technical solution: a green tire silica slurry uniform mixing device, including a support base 1, a mixing tank 2 fixedly connected to the top of the support base 1, a constant temperature jacket 3 fitted and fixedly connected to the mixing tank 2, a support frame 13 fixedly connected to the top of the mixing tank 2 via a bracket, a pretreatment device 4 fixedly connected to the top of the support frame 13, a feeding mechanism 5 fixedly connected to the top of the inner wall of the mixing tank 2, a feeding pipe 6 connected to the top of the mixing tank 2, the portion of the feeding pipe 6 extending into the interior of the mixing tank 2 communicating with the feeding mechanism 5, and a mixing device 7 rotatably connected through and to the bottom of the inner wall of the mixing tank 2. The bottom of the mixing tank 7 is connected to a first connecting pipe 8. The end of the first connecting pipe 8 away from the mixing device 7 is connected to the outlet of the conveying pump 9. The inlet of the conveying pump 9 is connected to the feeding mechanism 10. The bottom of the mixing tank 2 is connected to the inlet of the first solenoid valve 11. The outlet of the first solenoid valve 11 is connected to the discharge pipe 12. The pretreatment device 4 includes a pretreatment box 41. The top of the pretreatment box 41 is connected to a feeding nozzle 42. Arc-shaped screen plates 43 are fixedly connected to both sides of the inner wall of the pretreatment box 41. The arc-shaped screen plates 43 are evenly provided with first screen holes 44. The two sides of the inner wall of the pretreatment box 41 are located at... The portion above the arc-shaped screen plate 43 is rotatably connected to a rotating shaft 45. A first motor 410 is fixedly connected to one side of the pretreatment box 41. The drive shaft of the first motor 410 passes through the pretreatment box 41 and is fixedly connected to the rotating shaft 45. Crushing teeth 49 are evenly fixedly connected to the rotating shaft 45. A shaking mechanism 46 is fixedly connected to the inner wall of the feed nozzle 42. Cams 47 are fitted and fixedly connected to the portion of the rotating shaft 45 located on both sides of the crushing teeth 49. The bottom of the pretreatment box 41 is connected to the feed port of a second solenoid valve 48, and the discharge port of the second solenoid valve 48 is connected to the feed port of the second solenoid valve 48. The vibrating mechanism 46, which is connected to the top of the feed pipe 6, includes a fixed plate 461. A vibrating spring 462 is fixedly connected to the top of the fixed plate 461. A vibrating screen plate 463 is fixedly connected to the top of the vibrating spring 462. A second screen hole 464 is evenly opened on the top of the vibrating screen plate 463. A lifting rod 465 is fixedly connected to the bottom of the vibrating screen plate 463. Two sets of fixed plates 461 are symmetrically distributed on both sides of the inner wall of the feed nozzle 42. The bottom of the lifting rod 465 is slidably connected to the side of the cam 47. The diameter of the second screen hole 464 is larger than the diameter of the first screen hole 44.

[0018] In use, the silica powder is poured into the feed nozzle 42, and the first motor 410 is started. The drive shaft of the first motor 410 rotates, which in turn rotates the rotating shaft 45. The rotating shaft 45 rotates, which in turn rotates the cam 47 and the crushing teeth 49. The rotation of the cam 47 causes the lifting rod 465 to move up and down reciprocally. The up and down reciprocating motion of the lifting rod 465 causes the vibrating screen plate 463 to move up and down reciprocally. The up and down reciprocating motion of the vibrating screen plate 463 causes the silica powder to be continuously vibrated and screened in the feed nozzle 42, thus uniformly and initially screening the silica powder. At the same time, the screened silica powder is evenly passed through the second screen hole 464 and falls into the pretreatment box 41. The crushing teeth 49 crush the falling silica powder. The silica powder undergoes further crushing to make the agglomerated silica powder finer. After crushing, the silica powder is further finely sieved through the first sieve hole 44 on the arc-shaped sieve plate 43 to ensure the uniformity of the powder particle size. The qualified powder after sieving falls to the bottom of the pretreatment box 41 and enters the feed pipe 6 through the second solenoid valve 48. The shaking mechanism 46 makes the silica powder falling on the crushing teeth 49 more uniform and avoids accumulation, thus making the silica powder in contact with the crushing more uniform and improving the crushing effect. This completes the pretreatment operation of silica before mixing, thereby improving the subsequent mixing effect and avoiding agglomeration that affects the mixing effect.

[0019] For the second embodiment, please refer to... Figures 1-7 Based on the first embodiment, the present invention provides a technical solution: the feeding pipe 6 includes a pipe body 61, a second motor 62 is fixedly connected to one side of the pipe body 61, the drive shaft of the second motor 62 passes through the pipe body 61 and is fixedly connected to a driving bevel gear 63, a driven bevel gear 64 meshes with the side of the driving bevel gear 63, a first rotating rod 65 is fixedly connected to the bottom of the driven bevel gear 64, a rotating sleeve 66 is sleeved on and rotatably connected to the first rotating rod 65, the rotating sleeve 66 is fixedly connected to the inner wall of the pipe body 61 through a bracket, and the portion of the first rotating rod 65 located below the rotating sleeve 66 is sleeved and fixed. A spiral conveyor blade 67 is fixedly connected to the bottom of the first rotating rod 65, and a second rotating rod 68 is fixedly connected to the bottom of the side of the second rotating rod 68. Scrapers 69 are evenly fixedly connected to the bottom of the side of the second rotating rod 68. The feeding mechanism 5 includes a feeding box 51. Feeding holes 52 are evenly opened at the bottom of the inner wall of the feeding box 51. The feeding box 51 is fixedly connected to the top of the inner wall of the mixing tank 2. The top of the pipe body 61 is connected to the outlet of the second solenoid valve 48. The pipe body 61 passes through the mixing tank 2 and is connected to the top of the feeding box 51. The second rotating rod 68 extends into the inside of the feeding box 51. The bottom of the scraper 69 is in contact with the bottom of the inner wall of the feeding box 51.

[0020] In operation, the second solenoid valve 48 is activated to allow the pre-treated silica to enter the tube 61. Simultaneously, the second motor 62 is activated. The drive shaft of the second motor 62 rotates, driving the active bevel gear 63 to rotate. The active bevel gear 63 rotates, driving the driven bevel gear 64 to rotate. The driven bevel gear 64 rotates, driving the first rotating rod 65 to rotate. The first rotating rod 65 rotates, driving the spiral conveyor blade 67 to rotate. The spiral conveyor blade 67 steadily conveys the powder in the tube 61 downwards into the feed box 51, preventing the silica powder from getting stuck during descent and improving work efficiency. At the same time, the rotation of the first rotating rod 65 also drives the second rotating rod 68 to rotate. The rotation of the second rotating rod 68 drives the scraper 69 to rotate at the bottom of the inner wall of the feed box 51. The rotation of the scraper 69 prevents the powder from accumulating at the bottom of the inner wall of the feed box 51 and clogging the feed hole 52, allowing the powder to fall evenly from the feed hole 52 into the mixing tank 2, thus ensuring the uniformity of the feed and providing a good foundation for the uniform mixing of the silica slurry.

[0021] Third embodiment, please refer to Figures 1-8 Based on the second embodiment, the present invention provides a technical solution: the stirring device 7 includes a hollow rotating tube 71, the bottom side of the hollow rotating tube 71 is fitted with and fixedly connected to the output end of a belt drive mechanism 72, the input end of the belt drive mechanism 72 is fixedly connected to the drive shaft of a third motor 73, the side of the hollow rotating tube 71 is uniformly fixedly connected to arc-shaped stirring plates 74, two sets of arc-shaped stirring plates 74 are arranged symmetrically on the hollow rotating tube 71, the part of the side of the hollow rotating tube 71 located between the two sets of arc-shaped stirring plates 74 is uniformly fixedly connected to S-shaped stirring plates 75, the side of the S-shaped stirring plates 75 is uniformly provided with shearing holes 76, the side of the hollow rotating tube 71 is uniformly fixedly connected to L-shaped cleaning scrapers 77, the hollow rotating tube 71 penetrates the bottom of the inner wall of the stirring tank 2 and communicates with the first connecting pipe 8, the hollow rotating tube 71 is rotatably connected to the first connecting pipe 8, and the third motor 73 is fixedly connected to the bottom of the stirring tank 2 by a bracket.

[0022] During use, when mixing, the third motor 73 is started. The drive shaft of the third motor 73 rotates, driving the belt drive mechanism 72. The belt drive mechanism 72 rotates, driving the hollow rotating tube 71. The rotation of the hollow rotating tube 71 drives the arc-shaped stirring plate 74, the S-shaped stirring plate 75, and the L-shaped cleaning scraper 77 to rotate. The rotation of the arc-shaped stirring plate 74 can stir the silica slurry in the mixing tank 2 over a large area while drawing it towards the central S-shaped stirring plate 75. When the S-shaped stirring plate 75 rotates, the shearing holes 76 on its side can further shear and refine the slurry, enhancing the mixing effect and making the silica more evenly mixed with other materials. At the same time, the L-shaped cleaning scraper 77 scrapes against the inner wall of the mixing tank 2 during rotation, effectively preventing the slurry from adhering to the tank wall during mixing, avoiding waste of raw materials and troublesome subsequent cleaning. Through this multi-layered stirring, the mixing quality and efficiency of the silica slurry can be greatly improved, ensuring the stable quality of the final product.

[0023] For the fourth embodiment, please refer to [link / reference]. Figures 1-10 Based on the third embodiment, the present invention provides a technical solution: a feeding port 711 is uniformly opened on the side of the hollow rotating tube 71, a dispersing plate 712 is fixedly connected to the inner wall of the feeding port 711, and a dispersing hole 713 is uniformly opened on the side of the dispersing plate 712. The feeding mechanism 10 includes a second connecting pipe 101, a mixing auger 102 is fixedly connected to the inner wall of the second connecting pipe 101, and an auxiliary agent feeding pipe 103 and a latex feeding pipe 104 are respectively connected to both sides of the second connecting pipe 101. The end of the second connecting pipe 101 away from the auxiliary agent feeding pipe 103 is connected to the inlet of the conveying pump 9.

[0024] During use, the conveying pump 9 is started simultaneously with the feeding of silica. Additives enter the second connecting pipe 101 from the additive feed pipe 103, and latex enters the second connecting pipe 101 from the latex feed pipe 104. Through the negative pressure suction of the conveying pump 9, the additives and latex are forcibly conveyed and mixed by the mixing auger 102. This allows for preliminary mixing of the additives and latex before mixing with silica, improving the subsequent stirring and mixing effect. Simultaneously, as the hollow rotating pipe 71 rotates, the pre-mixed additives and latex are sprayed out from the feeding port 711. During spraying, the mixture of additives and latex impacts the dispersing plate 712. The dispersion holes 713 evenly distributed on the side of the dispersion plate 712 can further disperse these mixtures into fine droplets. These fine droplets can mix more evenly with the fed silica powder, further enhancing the mixing effect. This allows silica, additives, and latex to be mixed more fully and evenly. By adjusting the delivery flow rate of the delivery pump 9, the additives can be continuously sprayed out of the dispersion holes 713, and a negative pressure state can be maintained to prevent the mixed solution from entering the hollow rotating tube 71 from the dispersion holes 713. This results in the preparation of silica slurry products with more stable quality and better performance.

[0025] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
