The surface with the largest area among the blades is defined as the first connecting surface, the surface with the smallest area is defined as the second connecting surface, and the surface with an area between the first connecting surface and the second connecting surface is defined as the third connecting surface. One of the second connecting surfaces of the second blade is welded to one of the first connecting surfaces of the first blade, and the first connecting surface of the second blade is perpendicular to the first connecting surface of the first blade. The other second connecting surface of the second blade is welded to one of the third connecting surfaces of the third blade, and the third connecting surface of the second blade is perpendicular to the third connecting surface of the third blade.

[0007] Furthermore, the angle between the first connecting surface of the third slurry plate and the bottom surface of the pot body is an acute angle, and one of the third connecting surfaces of the second slurry plate is attached to the inner wall of the pot body.

[0008] Furthermore, the second blade includes a first connecting post and a first blade that are perpendicular to each other.

[0015] Beneficial effects:

[0016] As can be seen from the above technical solutions, this utility model provides a mixing pot. By employing various types of blades and setting different height parameters between the blade tips and the bottom surface of the pot, each stirring component can generate a layered shearing action during rotation. The materials in each layer are fully mixed under different shearing forces, avoiding localized uneven mixing or dead zones. The heating pad wrapped around the outside of the pot provides uniform heating and insulation for the inner materials, overcoming the shortcomings of traditional heating tubes that suffer from localized overheating or uneven heating. This maintains the materials at a constant temperature during stirring, effectively preventing changes in physical properties caused by temperature fluctuations. The discharge pipe adopts an elliptical cross-section design, which significantly increases the discharge area compared to a traditional circular cross-section, allowing for faster and more continuous discharge of the mixed materials. The first blade adopts a three-fold design, utilizing three rectangular blades to ensure structural stability during high-speed rotation and reduce the risk of component loosening due to mechanical impact. The second and third blades both adopt a T-shaped design and are fixed by detachable connecting columns and welding. The tight fit between the components ensures the stability of transmission and mixing, and facilitates subsequent disassembly, maintenance, and replacement.

[0026] In existing technologies, traditional mixing pots often use a single-structure stirring blade, commonly a simple straight plate or a fixed-angle blade. The simple blades lead to insufficient mixing of materials in some areas during the mixing process, which affects the uniformity of mixing. Some equipment is prone to forming dead corners during mixing, causing material to stagnate in some areas, which in turn leads to incomplete mixing.

[0027] Therefore, this utility model embodiment provides a mixing pot, referring to... Figure 1The apparatus includes a pot body 1 and a discharge pipe 2 located at the bottom of the pot body 1. The discharge pipe 2 has a baffle 201 at its inlet to block materials. A rotating shaft 3 is rotatably connected to the center of the bottom surface of the pot body 1. The rotating shaft 3 is perpendicular to the bottom surface of the pot body 1. An engine is connected to one end of the rotating shaft 3 outside the pot body 1, and a stirring assembly is connected to the other end of the rotating shaft 3 inside the pot body 1. The stirring assembly includes a first blade 4, a second blade 5, and a third blade 6. The first blade 4 is a folding blade, and the distance from the tip of the first blade 4 to the bottom surface of the pot body 1 is A. The second blade 5 is a T-shaped blade, and the distance from the tip of the second blade 5 to the bottom surface of the pot body 1 is B. The third blade 6 is a T-shaped blade, and the distance from the tip of the third blade 6 to the bottom surface of the pot body 1 is C. Wherein, A, B, and C are positive numbers, and C>A>B.

[0028] The basic framework of the mixing pot is formed by the connections between the pot body 1, the discharge pipe 2, the rotating shaft 3, the engine, and the stirring assembly. The rotating shaft 3, located at the center of the bottom surface of the pot body 1, is vertically installed to ensure symmetrical rotational transmission and reduce unbalanced vibration. The engine drives the internal stirring assembly via the rotating shaft 3, achieving continuous stirring. Based on the principle of mechanical transmission, the material undergoes shearing and flow under stress. The discharge pipe 2 has a baffle 201 at its bottom. The baffle 201 can be designed to rotatably connect between the outer wall of the pot body 1 and the inlet of the discharge pipe 2. When the baffle 201 rotates and blocks the inlet of the discharge pipe 2, it seals the material, preventing it from flying out during mixing. After mixing is complete, rotating the baffle 201 connects the discharge pipe 2 to the pot body 1, allowing material removal. The discharge port of the discharge pipe 2 is lower than its inlet, ensuring smooth material removal.

[0029] In some embodiments, reference is made to Figure 2 The first blade 4 is a three-folded blade and includes three rectangular blades, defined as the first blade 401, the second blade 402, and the third blade 403. The third blade 403 is detachably connected to the circumferential surface of the rotating shaft 3. The surface with the largest area among the blades is defined as the first connecting surface, the surface with the smallest area is defined as the second connecting surface, and the surface with an area between the first and second connecting surfaces is defined as the third connecting surface. One of the second connecting surfaces of the second blade 402 is welded to one of the first connecting surfaces of the first blade 401, and the first connecting surface of the second blade 402 is perpendicular to the first connecting surface of the first blade 401. The other second connecting surface of the second blade 402 is welded to one of the third connecting surfaces of the third blade 403, and the third connecting surface of the second blade 402 is perpendicular to the third connecting surface of the third blade 403.

[0030] By employing a combination of a three-fold, hinged blade and three rectangular blades, the structure achieves structural stability and multi-angle mixing functionality during high-speed rotation. The three-fold structure utilizes blades distributed at different positions to generate multi-layered, multi-directional shearing action on the material during rotation, conforming to the principle of fluid shear mixing. The blades are welded together, and the configuration of different connection surfaces ensures uniform force transmission and enhanced rigidity, guaranteeing that components do not deform or detach due to uneven stress during high-speed rotation.

[0031] In some embodiments, the angle between the first connecting surface of the third paddle plate 403 and the bottom surface of the pot body 1 is an acute angle, and one of the third connecting surfaces of the second paddle plate 402 is attached to the inner wall of the pot body 1.

[0032] The angle between the third impeller 403 and the bottom surface of the pot body 1, and the fit between the second impeller 402 and the inner wall of the pot body 1 are specified to ensure proper contact between the impellers and the pot body 1 during mixing, thereby improving the flow of materials. The third impeller 403 forms an acute angle with the bottom surface of the pot body 1, which, according to fluid mechanics principles, guides the material along the inclined surface during rotation, preventing dead zones. The second impeller 402, fitted to the inner wall of the pot body 1, assists in mixing and balances material distribution, while also reducing energy loss due to friction between the material and the pot body 1.

[0033] In some embodiments, the second blade 5 includes a first connecting post and a first blade that are perpendicular to each other. One end of the first connecting post is detachably connected to the center of the rotating shaft 3, and the other end of the first connecting post is welded to the first blade. The first blade is perpendicular to the bottom surface of the pot body 1.

[0034] A T-shaped structure design is proposed for the second blade 5, clarifying the structural form composed of the first connecting column and the first blade, and specifying a detachable connection method to facilitate assembly and subsequent maintenance. The T-shaped structure utilizes the vertical first blade to form a large force-bearing plane, enhancing the shearing effect on the material during mixing and ensuring uniform force distribution. The detachable connection design is based on the modular assembly principle, ensuring stable transmission while facilitating quick disassembly during equipment maintenance or replacement, improving the overall practicality and maintenance efficiency of the equipment.

[0035] In some embodiments, the third blade 6 includes a second connecting post and a second blade that are perpendicular to each other. A connecting rod 7 is welded to the first blade 401. The end of the connecting rod 7 that is not connected to the first blade 401 is welded to the second connecting post. The first connecting post is perpendicular to the connecting rod 7. The other end of the second connecting post is welded to the second blade. The second blade is perpendicular to the bottom surface of the pot body 1.

[0036] By setting a connecting rod 7 on the first slurry plate 401 and welding it to the second connecting column, a stable force transmission path is formed. This design utilizes the interlocking principle in mechanical structures to effectively disperse the centrifugal force generated by rotation. The vertical arrangement of the second blades can generate a shear force perpendicular to the bottom surface of the pot body 1, enabling the material in the mixing process to form a strong flow and redispersion effect between different force zones.

[0037] In some embodiments, there are two first blades 4. One first blade 4 has a connecting rod 7 welded between the first blade 401 and the second connecting post, and the other first blade 4 has a connecting rod 7 welded between the first blade 401 and the second connecting post. A connecting rod 7 is welded between the first blades 401 of the two first blades 4.

[0038] The number of first blades 4 is limited, and the two first blades 4 are fixed together and to the second connecting column by connecting rods 7 to ensure symmetrical overall structural layout and balanced force distribution. By setting two first blades 4 and using connecting rods 7 to form an equilateral triangle, multi-point force balance is achieved. This balanced structure helps reduce vibration caused by uneven torque during operation. In some embodiments, the triangle formed by the three connecting rods 7 is an equilateral triangle. The equilateral triangle structure can evenly distribute centrifugal force on each blade during rotation, making the mixing effect more stable, while ensuring coordinated cooperation between blades to achieve optimized material shearing effect. The equilateral triangle structure formed by the connecting rods 7 ensures that there is the same distance between each connection point, thereby achieving structural force balance. Mechanically, this ensures that each connecting rod 7 is not easily deformed under high-speed rotation, thus improving the stability and lifespan of the overall mixing system.

[0039] In some embodiments, the thickness range of the first paddle plate 401, the second paddle plate 402, the third paddle plate 403, the first blade, and the second blade is [10, 15], with the thickness unit being mm.

[0040] The thickness of the blades was limited to ensure that each component met structural strength requirements while also achieving the desired mixing and shearing effects. The thickness range was set based on material mechanics and process requirements, ensuring the rigidity of the blade structure without increasing equipment inertia and reducing mixing efficiency due to excessive thickness. By controlling the thickness, the mixing components can consistently perform the expected shearing and mixing actions during operation, thereby improving the overall mixing effect.

[0041] In some embodiments, the cross-section of the discharge pipe 2 is elliptical. The elliptical cross-section of the discharge pipe 2 is used to increase the discharge channel area and improve the discharge efficiency of the mixed material. The elliptical cross-section design is based on fluid mechanics principles. Compared to a traditional circular cross-section, it can increase the discharge area while maintaining the channel flow velocity, reducing the risk of blockage, helping to achieve a continuous and stable discharge process, meeting the requirement of rapid material discharge during high-load mixing, and facilitating a smooth transition of material flow.

[0042] In some embodiments, a heating pad 8 is wrapped around the outer wall of the pot body 1. The heating pad 8, which utilizes existing heating and heat-insulating devices powered by an external power source, is primarily used to heat and insulate the materials inside the pot body 1, maintaining a suitable temperature during mixing. Based on the principle of heat conduction, the heating pad 8 achieves uniform heat transfer through close contact with the pot body 1, creating a relatively stable temperature field inside the pot body 1. Uniform heating and heat insulation help maintain the stability of the material's physical properties, preventing changes in properties due to excessively low or high local temperatures, thereby ensuring the mixing effect and the stability of subsequent processing steps.

[0043] The mixing pot features a rational overall structural design, with components securely fixed through welding and disassembly connections, ensuring high efficiency and reliability during extended operation. In practical use, the engine starts, driving the rotating shaft 3 to rotate, and the mixing components rotate synchronously. Each blade continuously and uniformly mixes the thermoplastic elastomer material in layers within the pot body 1. Simultaneously, the external heating pad 8 of the pot body 1 maintains a constant temperature for the inner material, ensuring it reaches the predetermined physical properties during mixing. After mixing, the material is discharged through the elliptical discharge pipe 2, allowing for rapid discharge and meeting the demands of continuous production.

[0044] In summary, the mixing pot provided by this utility model, by employing multiple types of blades and setting different height parameters between the blade tips and the bottom surface of the pot body 1, enables each stirring component to generate a layered shearing action during rotation. The materials in each layer are fully mixed under different shearing forces, avoiding localized uneven mixing or dead zones. Multiple first blades 4 are fixed by equilateral triangular connecting rods 7, which helps to achieve balanced force distribution at multiple points, thereby reducing uneven mixing caused by vibration. The heating pad 8 wrapped around the outside of the pot body 1 provides uniform heating and insulation of the inner materials, overcoming the shortcomings of traditional heating tubes such as localized overheating or uneven heating. It maintains the materials at a constant temperature during stirring, effectively avoiding changes in physical properties caused by temperature fluctuations. The tight fit between the heating pad 8 and the pot body 1 ensures efficient heat transfer, resulting in a more uniform temperature distribution throughout the mixing area, thus improving the stability of mixing and subsequent processing. The discharge pipe 2 adopts an elliptical cross-section design, which significantly increases the discharge area compared to a traditional circular cross-section, allowing for faster and more continuous discharge of mixed materials. The first blade 4 adopts a three-fold design, utilizing three rectangular blades to ensure structural stability during high-speed rotation and reduce the risk of component loosening due to mechanical impact. The second and third blades 6 both employ a T-shaped design and are fixed via detachable connecting columns and welding. The tight fit between components ensures stable transmission and mixing while facilitating subsequent disassembly, maintenance, and replacement. The equilateral triangular layout of the connecting rod 7 not only achieves balanced force distribution mechanically but also maintains the overall rigidity of the equipment during long-term operation, extending its service life.
