For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0027] The following is for reference. Figures 1-4 The pyrolysis stirring device 100 according to the embodiment of the present utility model is described. The application field of the pyrolysis stirring device 100 is not limited. It can be applied to the pyrolysis treatment of chemical raw materials, or it can be applied to the environmental protection field, the pharmaceutical manufacturing field, and the food processing industry, etc.
[0028] like Figure 1 As shown, the pyrolysis stirring device 100 of this utility model embodiment includes: a stirring vessel 10, a stirrer 20, and a reinforcing fixing frame 30.
[0029] The mixing vessel 10 is used to contain the materials to be pyrolyzed and stirred. The agitator 20 is built into the mixing vessel 10 to achieve uniform mixing of the materials.
[0030] The reinforced bracket 30 is used to firmly support the mixing vessel 10 and the agitator 20 to ensure stable operation of the device and improve the overall durability of the structure.
[0031] The mixing vessel 10 includes a cylinder 11, a top cover 13, and a bottom plate 15, with the top cover 13 and the bottom plate 15 connected to the upper and lower ends of the cylinder 11.
[0032] Here, the cylinder 11 is used to contain the pyrolysis material. The top cover 13 is connected to the upper end of the cylinder 11. The bottom plate 15 is sealed to the lower end of the cylinder 11. The bottom plate 15 is used to support the weight of the cylinder 11 and ensure that the material does not leak. At the same time, the bottom plate 15 can also enhance the structural stability of the cylinder 11.
[0033] The stirrer 20 includes a stirring shaft 22, stirring blades 24, and a drive unit 26. The drive unit 26 is connected to the top cover 13. The upper end of the stirring shaft 22 is connected to the drive unit 26, and the lower end extends through the top cover 13 into the mixing vessel 10. The stirring blades 24 are connected to the stirring shaft 22.
[0034] Here, the stirring shaft 22 is responsible for transmitting power and driving the stirring blades 24 to rotate. The stirring blades 24 directly act on the material, realizing the mixing and shearing of the material. The drive unit 26 is connected to the top cover 13 and provides rotational power to the stirring shaft 22. The upper end of the stirring shaft 22 is firmly connected to the drive unit 26, and the lower end extends through the top cover 13 into the interior of the mixing vessel 10.
[0035] Optionally, there are multiple stirring blades 24, which are spaced apart along the height of the stirring shaft 22. This ensures that the material is stirred in all directions within the vessel.
[0036] like Figure 1 As shown, the reinforcing bracket 30 is connected to the top cover 13. This provides additional support for the stirred tank 10, and the reinforcing bracket 30 and the drive component 26 are mounted on the same frame 50. This also enhances the stability of the drive component 26, enabling it to output greater stirring torque and higher stirring speed during stirring. At the same time, it reduces or even avoids the shaking and vibration that may occur in the stirring shaft 22 during stirring, ensuring the high efficiency and stability of the pyrolysis stirring operation.
[0037] It is worth noting that when the drive component 26 is more securely installed through the reinforcing bracket 30, the stability and load-bearing capacity of the drive component 26 are improved to a certain extent.
[0038] In addition, the reinforced support frame 30 provides more possibilities for the stirring device: on the one hand, the number of stirring blades 24 can be increased, allowing for more thorough mixing of materials, thereby improving stirring efficiency and making the pyrolysis reaction more uniform and rapid. On the other hand, the length of the stirring shaft 22 can be increased to expand the stirring range, making it suitable for larger capacity stirred tanks 10, further enhancing the processing capacity and adaptability of the pyrolysis stirring device 100. These improvements, working together, will greatly enhance the overall performance and efficiency of the pyrolysis stirring operation.
[0039] Therefore, the pyrolysis stirring device 100 according to this embodiment of the present invention ensures the high efficiency and stability of the stirring operation by setting a reinforcing fixing frame 30. At the same time, this pyrolysis stirring device 100 also has good expandability, which not only improves the adaptability of the stirring device, but also enhances its ability to meet different stirring needs and adapt to larger capacity stirring tanks 10 to a certain extent.
[0040] In this application, the shape of the reinforcing bracket 30 is highly flexible, and it can be a frame structure. This frame structure can include various shapes, such as triangles, quadrilaterals, polygons, or irregular shapes. It can also include individual components, such as support beams. These support beams can be straight beams, curved beams, or irregularly shaped beams adapted to the shape of the top cover 13.
[0041] Optionally, the reinforcing bracket 30 can be attached to the upper surface of the top cover 13 or embedded in the top cover 13.
[0042] In some alternative embodiments, combined with Figure 1 The pyrolysis stirring device 100 further includes a flow-dispersing element 40. The flow-dispersing element 40 is located inside the stirring vessel 10 and is disposed on at least one of the cylinder 11 and the bottom plate 15.
[0043] By setting the flow-deflecting element 40, the flow path of the material during the stirring process can be effectively changed, increasing the chances of collision and shearing between materials, thereby improving the pyrolysis efficiency and stirring uniformity.
[0044] In some alternative embodiments, the spoiler 40 may be a plate or other protrusion.
[0045] Optionally, the plate can be constructed in the shape of an arc, wave, etc., to guide the material to produce a turbulent flow effect.
[0046] In some embodiments, the flow disruptor 40 is disposed on the cylinder 11. By changing the flow trajectory of the material in the stirred tank 10, the interaction between the materials is enhanced, thereby improving the pyrolysis efficiency and the uniformity of mixing.
[0047] In some embodiments, the baffle 40 is disposed on the bottom plate 15. In this way, the baffle 40 can effectively prevent the material from accumulating at the bottom of the stirred tank 10, avoid the formation of dead corners, and ensure that the material can be fully stirred and uniformly pyrolyzed during the pyrolysis process, thereby improving pyrolysis efficiency and product quality.
[0048] To improve pyrolysis efficiency, in some optional embodiments, both the cylinder 11 and the bottom plate 15 are provided with baffles 40.
[0049] In some optional embodiments, the spoiler 40 includes a first spoiler 41. The first spoiler 41 is connected to the cylinder 11 and extends along the length of the cylinder 11.
[0050] This design enhances the turbulence effect of the first baffle 41. When the material flows through the inner wall of the cylinder, the first baffle 41 can effectively intercept and change the flow direction of the material, causing turbulence, thereby increasing the chance of collision between materials and improving the pyrolysis stirring efficiency.
[0051] In some alternative embodiments, the first spoiler 41 is directly connected to the cylinder 11. Here, the first spoiler 41 can be firmly fixed to the inner wall of the cylinder 11 by welding, bolting, or other fastening methods. This direct connection ensures a tight fit between the first spoiler 41 and the cylinder 11, thereby effectively guiding and controlling the flow of materials.
[0052] Alternatively, the first baffle 41 can be spaced apart from the cylinder 11. Here, the first baffle 41 can be suspended within the cylinder 11 via a bracket, connecting rod, or other connecting structure. This spaced arrangement allows for a certain flow space between the first baffle 41 and the cylinder 11, which helps reduce material aggregation and promotes uniform mixing. Furthermore, the spaced arrangement facilitates maintenance and replacement of the first baffle 41, improving the maintainability of the pyrolysis stirring device 100.
[0053] According to some optional embodiments, see Figure 2 and Figure 3 There are multiple first spoilers 41, which are spaced apart along the circumference of the cylinder 11. The included angle between two adjacent first spoilers 41 is 45°-80°.
[0054] For example, the included angle between two adjacent first baffles 41 can be 45°, 50°, 60°, 75°, or 80°. By controlling the included angle between the first baffle 41 and the stirring shaft 22 to 45°-80°, the number of first baffles 41 can be increased, which can more effectively break the laminar flow state in the fluid, promote turbulence and mixing of the fluid, and thus improve pyrolysis efficiency and stirring uniformity.
[0055] In some alternative embodiments, the distance between the upper end of the first spoiler 41 and the upper end of the cylinder 11 is L1, the length of the cylinder 11 is L0, and L1 accounts for 20%-25% of L0. For example, L1 accounts for 20%, 21%, 23%, 24%, or 25% of L0. This arrangement ensures that the first spoiler 41 can effectively act on the material without being too close to the upper end of the cylinder 11, reducing the use of material for the first spoiler 41 and avoiding material waste.
[0056] The distance between the lower end of the first spoiler 41 and the lower end of the cylinder 11 is L2, and L2 accounts for 5%-10% of L0. For example, L2 accounts for 5%, 6%, 7%, 9%, and 10% of L0. This setting ensures that the first spoiler 41 can effectively act on the material without being too close to the lower end of the cylinder 11, reducing the use of material for the first spoiler 41 and avoiding material waste.
[0057] In some optional embodiments, the agitator 40 further includes a second agitator 42, which is laterally disposed below the agitator 20.
[0058] The second baffle plate 42 is located below the agitator 20, which can effectively reduce the accumulation of solid particles at the bottom of the agitator 20. It is suitable for stirring suspensions formed by solid particles, improving production efficiency, saving stirring power, and increasing stirring effect.
[0059] Specifically, during the rotation of the agitator 20, the material is subjected to a downward force generated by the agitator blades 24, which causes some of the material to tend to accumulate at the bottom of the agitator 20. However, when this material attempts to accumulate at the bottom, it encounters the second baffle 42.
[0060] The second baffle 42 is located at the bottom and can effectively prevent the accumulation of materials at the bottom. It not only breaks up the accumulated materials, but also disperses these broken materials to other areas of the cylinder 11, promoting the dynamic circulation of materials in the entire mixing vessel 10, thereby improving the mixing uniformity of materials and increasing the pyrolysis stirring efficiency.
[0061] In some alternative embodiments, the second spoiler 42 may be a flat plate, an arc-shaped plate, or the second spoiler 42 may also be a serrated plate or a spiral plate, etc.
[0062] According to the pyrolysis stirring apparatus 100 of this utility model embodiment, such as Figure 4 As shown, the second spoiler 42 has a perforation 421.
[0063] These perforations 421 allow material to pass through, reduce material accumulation near the second baffle 42, and improve the uniformity of material mixing.
[0064] In some specific embodiments, the perforations 421 on the second baffle 42 are located at the lower edge. This allows for more effective guidance of material passing under the second baffle 42. This design prevents material accumulation in front of the baffle, ensuring smooth flow of material throughout the mixing chamber. In particular, as the agitator 20 rotates, the material is carried up and passes through the perforations 421, further promoting uniform distribution and mixing of the material.
[0065] In some alternative embodiments, refer to Figure 1 The reinforced fixing frame 30 includes at least one fixing plate 301, which is an arc-shaped plate. One end of the arc-shaped plate is welded to the frame 50, and the inner arc edge of the arc-shaped plate is welded to the top cover 13. This design makes the overall structure stronger.
[0066] First, one end of the arc-shaped plate is welded to the frame 50, enhancing the connection strength between the fixed plate 301 and the frame 50 and ensuring that the frame 50 can be effectively supported and stabilized. When the drive component 26 generates force, the force is first transmitted to the frame 50, and then transmitted to the fixed plate 301 through the welding connection.
[0067] Secondly, by constructing the fixing plate 301 as an arc-shaped plate, it can better adapt to the curved contour of the top cover 13. This not only improves the fit between the fixing plate 301 and the top cover 13, but also enhances the strength and stability of the entire structure.
[0068] The inner arc edge of the curved plate fits tightly against the top cover 13. This tight fit increases the contact area between the two and ensures a uniform distribution of force. Therefore, the force generated by the drive component 26 can be smoothly transmitted from the frame 50 to the top cover 13, thereby improving the stability and load-bearing capacity of the entire structure.
[0069] In some alternative embodiments, see Figure 2 and Figure 3 When there are at least two fixing plates 301, the fixing plates 301 include: a first fixing plate 31 and a second fixing plate 32.
[0070] Optionally, both the first fixing plate 31 and the second fixing plate 32 are curved plates, and their lower ends are welded to the top cover 13. This configuration allows the first fixing plate 31 and the second fixing plate 32 to better adapt to the curved contour of the top cover 13, enhancing fit and structural strength. The welded connection of the lower ends of both the first fixing plate 31 and the second fixing plate 32 to the top cover 13 ensures uniform force distribution and efficient transmission, while also improving the overall structural stability and load-bearing capacity.
[0071] The plane containing the first fixing plate 31 and the plane containing the second fixing plate 32 are intersected.
[0072] By setting it in this way, the overall structure is supported in multiple directions, effectively preventing the displacement problem caused by the shaking generated by the driving member 26 during the working process, thereby improving the stability and reliability of the stirring process.
[0073] Optionally, the first fixing plate 31 and the second fixing plate 32 can form a structure similar to an "X", a "rice" shape or a "well" shape. This structure with intersecting planes can provide uniform supporting forces in multiple directions. The first fixing plate 31 and the second fixing plate 32 evenly distribute the load in multiple directions, ensuring that each fixing plate 301 can have balanced supporting forces and can also evenly disperse the forces to the middle area of the structure, effectively preventing deformation or damage that may be caused by local stress concentration, and improving the reliability and durability of the equipment.
[0074] In some alternative embodiments, refer to Figure 2 and Figure 3 , a surrounding cavity 51 is formed inside the frame 50, and the driving member 26 is located inside the surrounding cavity 51. The driving member 26 includes a driving motor 261 and a speed reducer 262 connected below the driving motor 261, and the driving motor 261 is connected to the stirring shaft 22 through the speed reducer 262.
[0075] In the above technical solution, the driving motor 261 serves as the power source of the entire system, and it is responsible for providing rotational power.
[0076] Optionally, the driving motor 261 can be an AC motor or a DC motor. Specifically, different types of motors can be selected according to requirements, and there is no limitation in this application.
[0077] The driving motor 261 is installed above the top cover 13, making it convenient for heat dissipation and maintenance.
[0078] The speed reducer 262 is used to reduce the rotational speed output by the driving motor 261 and increase the torque, enabling the stirring device to perform stirring work with greater force.
[0079] A surrounding cavity 51 is formed inside the frame 50. This surrounding cavity 51 provides an installation space for the driving member 26, thereby improving the safety and stability of the driving member 26. In addition, during the stirring process, the forces generated by the driving member 26 are evenly transmitted to the entire top cover 13 through the frame 50, enabling these forces to be dispersed throughout the structure and avoiding deformation or damage caused by local stress concentration.
[0080] In some alternative technical solutions, multiple first fixing plates 31 are arranged in parallel or non-parallel at a certain interval. In still other alternative technical solutions, multiple second fixing plates 32 are arranged in parallel or non-parallel at a certain interval.
[0081] Here, the plane containing the second fixing plate 32 and the plane containing the first fixing plate 31 can intersect perpendicularly or at other angles. By setting multiple fixing plates 301 around the frame 50, multi-directional limiting and support of the frame 50 can be achieved. This multi-directional limiting and support can improve the stability of the overall structure and reduce possible shaking or displacement during operation. When the drive component 26 generates rotational force during startup or operation, these forces can be evenly distributed to the surrounding multiple fixing plates 301. Each fixing plate 301 can share a portion of the load, avoiding excessive pressure on a single component, thereby reducing the risk of local failure.
[0082] In some specific embodiments, see Figure 2 and Figure 3 The plane where the first fixing plate 31 is located is perpendicular to the plane where the second fixing plate 32 is located.
