[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0026] To address the technical problem of ineffective utilization of impact energy during material feeding, leading to energy waste, this invention provides a feeding buffer stirring mechanism and mixing tank. By incorporating a stirring component, a buffer component, and a transmission component, the impact force during feeding can be converted into rotational power and transmitted to the stirring component, thereby achieving self-driven stirring operations and reducing energy consumption and costs. Furthermore, this design not only improves stirring efficiency but also ensures uniform mixing of materials within the tank, enhancing product quality. This device effectively mitigates the impact generated when materials enter the tank and utilizes the power generated by the impact to drive the stirring component, improving energy utilization efficiency and reducing production costs.
[0027] Please see Figures 1 to 3In a first aspect, embodiments of this application provide a feeding buffer stirring mechanism, including: a stirring assembly 1, a buffer assembly 2, and a transmission assembly 3. The stirring assembly 1 includes a central shaft 11 and a stirring element 12. The central shaft 11 is rotatably disposed inside a tank 7, and the stirring element 12 is connected to the central shaft 11. The buffer assembly 2 includes a rotating shaft 21 and at least three buffer elements 22. The at least three buffer elements 22 are disposed on the outer periphery of the rotating shaft 21, and the rotation path of the buffer elements 22 is partially overlapped with the feeding direction of the tank 7, so as to generate power to drive the rotating shaft 21 to rotate when receiving feeding impact. The transmission assembly 3 connects the central shaft 11 and the rotating shaft 21, and is used to drive the central shaft 11 to rotate through the transmission assembly when the rotating shaft 21 rotates.
[0028] In this device, the buffer assembly 2 consists of a rotating shaft 21 and at least three buffer members 22 evenly arranged on the outer periphery of the rotating shaft 21. The rotation path of the buffer members 22 is configured to partially overlap with the feeding direction of the tank 7. When the material enters the tank 7 through the feed end, the buffer member 22 first contacts the material, which not only effectively buffers the impact force when the material is fed, but also the impact force of the material acts on the buffer member 22, driving the buffer member 22 to rotate around the rotating shaft 21, thereby driving the rotating shaft 21 to rotate. Since the rotating shaft 21 and the central shaft 11 are connected by the transmission assembly 3, the rotational power of the rotating shaft 21 can be transmitted to the central shaft 11, causing the central shaft 11 to rotate. Therefore, the stirring member 12 can be driven to rotate with the central shaft 11 to perform stirring operations inside the tank 7.
[0029] It should be noted that the material discharged from the discharge end of tank 7 can be gaseous, liquid, or solid, which can meet a variety of different production needs. Among them, 3 to 6 buffer components 22 are provided to achieve continuous buffering and drive effect on the rotating shaft 21 and the stirring assembly 1, ensuring the stability and efficiency of the stirring operation.
[0030] Furthermore, to improve buffering and driving performance, please refer to [link / reference]. Figure 2 and Figure 3 In some embodiments, the cross-sectional area of the buffer member 22 in the radial direction of the rotating shaft 21 is greater than the cross-sectional area of the feed end of the tank body 7. When the buffer member 22 corresponds to the feed end, the cross-sectional area of the side corresponding to the feed end is greater than the cross-sectional area of the feed end. Therefore, the buffer member 22 can better receive the material entering from the feed end, so as to improve the buffering effect.
[0031] Preferably, please refer to Figures 2 to 5In this embodiment, the central shaft 11 is centrally and vertically arranged inside the tank 7. The stirring component 12 includes multiple stirring blades distributed on the outside of the central shaft 11. The ends of the stirring blades are fixed to the outside of the central shaft 11 by welding or bolting. The buffer component 22 includes a buffer plate 221. The end of the buffer plate 221 near the rotating shaft 21 is fixed to the rotating shaft 21 by welding or bolting. In order to enhance the driving force, a groove 222 is provided on one side of the buffer plate 221. The two ends of the groove 222 penetrate through the two ends of the buffer plate 221, and its groove wall is composed of two inclined surfaces. When the buffer plate 221 rotates to a position corresponding to the feed end of the tank 7, the groove 222 on the buffer plate 221 faces the feed direction of the feed end of the tank 7. At this time, the material entering from the feed end of the tank 7 will first impact the buffer plate 221. Since the groove wall of the groove 222 is composed of two inclined surfaces, the material enters the groove 222 after contacting the inclined surfaces. The material's gravity and impact force can push the buffer plate 221 to rotate around the rotating shaft 21. At the same time, the structural design of the groove 222 allows the buffer plate 221 to rotate downwards, enabling the material to be fully discharged from the groove 222, avoiding material residue on the buffer plate 221 and increasing the weight of the buffer assembly 2.
[0032] Of course, in other possible embodiments, the buffer 22 and the agitator 12 can also adopt other structural forms and can be designed into different shapes, such as spiral, fan-shaped or other geometric shapes.
[0033] To further improve the mixing effect, please refer to [link / reference]. Figure 1 and Figure 2 In some possible embodiments, the feeding buffer stirring mechanism further includes a driving component, which includes a motor 4 and an electromagnetic clutch. The motor 4 is fixedly mounted on the top of the tank 7. The motor 4 has an off mode and an active mode. The electromagnetic clutch is located between the driving end of the motor 4 and the central shaft 11. When the electromagnetic clutch is energized, the driving end of the motor 4 engages with the central shaft 11, and the motor 4 is in the active mode. At this time, the central shaft 11 can be driven to rotate by the motor 4, ensuring continuous stirring. When the electromagnetic clutch is de-energized, the driving end of the motor 4 disengages from the central shaft 11, and the motor 4 is in the off mode. At this time, when the material pushes the buffer assembly 2 and the stirring assembly 1 to rotate, the motor 4 will not be forcibly dragged, avoiding damage to the motor 4 or energy consumption.
[0034] Further, please refer to Figure 2 In some possible embodiments, the rotating shaft 21 is perpendicular to the feeding direction of the central shaft 11 and the feeding end of the tank 7. The rotating shaft 21 is set horizontally and the central shaft 11 is set vertically. Both can rotate inside the tank 7.
[0035] To achieve transmission between rotating shaft 21 and central shaft 11, please refer to... Figure 2 and Figure 3In some possible embodiments, the transmission assembly 3 includes a first gear 31 and a second gear 32 that mesh with each other. The first gear 31 is used to connect to the rotating shaft 21 and can rotate as the rotating shaft 21 rotates. The second gear 32 is fixedly mounted on the central shaft 11. Since the first gear 31 and the second gear 32 mesh with each other, the first gear 31 can drive the second gear 32 to rotate, thereby realizing the rotation of the central shaft 11. In addition, the transmission assembly 3 can also adopt other methods such as belt drive and chain drive.
[0036] Furthermore, in some possible embodiments, the diameter of the first gear 31 is larger than the diameter of the second gear 32, so that the first gear 31 can drive the second gear 32 to rotate at a higher speed, thereby increasing the stirring speed of the stirring component 12 and enhancing the stirring effect.
[0037] Furthermore, please refer to Figure 2 In some possible embodiments, the transmission assembly 3 further includes a connecting shaft 33 and a one-way bearing 34. The connecting shaft 33 is fixedly mounted on the first gear 31. The connecting shaft 33 is connected to the rotating shaft 21 through the one-way bearing 34. When the material pushes the rotating shaft 21 to rotate, it can transmit power to the central shaft 11. When the central shaft 11 rotates under the drive of the motor 4, it will not drive the rotating shaft 21 in the opposite direction, thus avoiding energy loss.
[0038] To prevent materials from entering transmission component 3 and affecting its operation, please refer to [link / reference needed]. Figure 2 and Figure 6 In some possible embodiments, a gearbox 5 is provided at the mounting positions of the first gear 31 and the second gear 32. Both the first gear 31 and the second gear 32 are installed inside the mounting box. The connecting shaft 33 and the central shaft 11 are rotatably connected to the gearbox 5 via bearings, providing support for the gearbox. A sealing ring is also provided on the gearbox 5 to seal its interior, ensuring its airtightness and preventing material from entering. A fixing plate 6 is fixedly installed on the outside of the gearbox 5, and its outer wall is fixedly connected to the tank body 7 to secure the gearbox 5.
[0039] In some possible embodiments, the fixing plate 6 is positioned above the rotating shaft 21, and a through groove 61 is provided on the fixing plate 6 at a position corresponding to the buffer assembly 2, allowing material to fall onto the buffer plate 221 through the groove 61. Simultaneously, the width of the through groove 61 is slightly larger than the width of the entire buffer assembly 2 to prevent material from getting stuck between the fixing plate 6 and the buffer plate 221 when falling in. A guide ramp 62 is also provided at the edge of the through groove 61, gradually widening towards the feed end of the tank 7 to guide the material to fall more smoothly onto the buffer plate 221.
[0040] Secondly, this application also provides a mixing tank, including a feeding buffer stirring mechanism as described above and a tank body 7. A motor 4 is mounted on the top of the tank body 7, the top end of a central shaft 11 is rotatably connected to the tank body 7, and a discharge port is provided at the bottom of the tank body 7.
[0041] To better understand this utility model, the following is combined with... Figures 1 to 6 The technical solution of this utility model is described in detail as follows: During feeding, the electromagnetic clutch is de-energized, and the motor 4 is in the off mode. The material enters from the feed end of the tank 7 and first impacts the buffer plate 221 of the buffer assembly 2. The force generated by the impact of the material drives the buffer plate 221 to rotate around the rotating shaft 21, which in turn drives the rotating shaft 21 and the first gear 31 to rotate. The rotation of the first gear 31 further drives the second gear 32 and the central shaft 11 fixedly connected to it to rotate, thereby driving the stirring component 12 to perform stirring operations in the tank 7, achieving uniform mixing of the material. After feeding is completed, the electromagnetic clutch is energized, and the motor 4 switches to the active mode. At this time, the motor 4 can drive the central shaft 11 to continue rotating, ensuring the continuity and efficiency of the stirring operation.
[0042] This invention, by incorporating a stirring assembly 1, a buffer assembly 2, and a transmission assembly 3, converts the impact force during feeding into rotational power, which is then transmitted to the stirring assembly 1. This achieves self-driving of the stirring operation, reducing energy consumption and costs. Furthermore, this design not only improves stirring efficiency but also ensures uniform mixing of materials within the tank 7, enhancing product quality. This device effectively mitigates the impact generated when materials enter the tank 7 and utilizes the power generated by the impact to drive the stirring assembly 1, improving energy efficiency and reducing production costs.
