Description

Technical Field

[0001] This utility model relates to the field of mixing technology, specifically to a material mixing device. Background Technology

[0002] In the production of high-viscosity food materials such as chocolate, candy, and sauces, the mixing process is the core step to ensure a smooth texture and uniform composition. Currently, most mixing devices used in the industry employ a single stirring method, such as anchor mixers or simple propeller blades. These structures have significant limitations in practical applications.

[0003] First, for materials whose viscosity continuously changes during the process, a single agitator cannot simultaneously meet the needs of macroscopic circulation and microscopic shearing, often resulting in uneven mixing and dead zones. This is especially true as a material adhesion layer easily forms on the tank wall, affecting heat transfer efficiency and causing localized overheating and coking, while also wasting raw materials. Second, when powdered additives (such as sugar powder and milk powder) are added to high-viscosity base materials, the lack of an effective online dispersion mechanism easily leads to the formation of difficult-to-disperse clumps, severely impacting the fineness of the final product. Furthermore, the independent scraper mechanism added to solve the wall scraping problem often requires a complex multi-power source drive system, resulting in complex equipment structure, high manufacturing costs, and inconvenient maintenance.

[0004] Therefore, it is necessary to invent a material mixing device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a material mixing device that, through the cooperation of a mixing tank and a multi-functional mixing mechanism, solves the problem in the prior art where a material adhesion layer forms on the tank wall, which not only affects heat transfer efficiency and leads to local overheating and coking, but also lacks an effective online dispersion mechanism and easily forms "clumps" that are difficult to break up.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a material mixing device, comprising a mixing tank, wherein a multi-functional mixing mechanism is provided inside the mixing tank, the multi-functional mixing mechanism including a main stirring shaft rotatably connected to the top wall of the mixing tank, a spiral conveying blade fixedly connected to the outer wall of the upper half of the main stirring shaft, a high-speed dispersing disc fixedly connected to the outer wall of the lower half of the main stirring shaft, the surface of the high-speed dispersing disc having several sets of dispersing holes, two sets of connecting frames fixedly connected to the outer wall of the main stirring shaft, the two sets of connecting frames being located at the top and bottom of the main stirring shaft respectively, and movable shafts rotatably connected to the two ends of the connecting frames, a spiral scraper fixedly connected to the outer wall of the movable shaft, the two sets of spiral scrapers having complementary cleaning ranges and the same spiral direction, thereby integrating the upper spiral conveying blade, the lower high-speed dispersing disc, and the spiral scraper driven by the connecting frames and the movable shaft through the main stirring shaft, realizing the composite functions of conveying, dispersing, and wall scraping cleaning.

[0007] Preferably, a mounting bracket is fixedly connected to the top of the mixing tank, and a mixing motor is fixedly connected to the top wall of the mounting bracket. The mounting bracket provides a stable and reliable mounting foundation for the mixing motor, ensuring the smoothness of power output.

[0008] Preferably, the output end of the mixing motor is fixedly connected to the main stirring shaft, and a discharge valve is provided below the main stirring shaft. The discharge valve is installed at the bottom of the mixing tank, which clarifies the direct driving relationship between the mixing motor and the main stirring shaft. By setting the discharge valve at the bottom of the tank, the controllable discharge of materials after mixing is achieved.

[0009] Preferably, a bracket mounting ring is fixedly connected to the outer wall of the mixing tank, and a movable gear is fixedly connected to the top of the movable shaft. The bracket mounting ring enhances the structural stability and provides a prerequisite for the installation of the movable gear, which is the key structural foundation for realizing the self-rotation of the spiral scraper.

[0010] Preferably, the outer wall of the movable gear is engaged with a fixed gear ring, which is fixedly connected to the inner wall of the top of the mixing tank. The movable gear rolls along the fixed gear ring, thereby forcing the movable shaft to rotate.

[0011] Preferably, a feed pipe is fixedly connected to the top of the mixing tank, and a Venturi tube is fixedly connected to the inner wall of the feed pipe and the Venturi tube is located inside the mixing tank, so as to pre-disperse the material at the moment of feeding by utilizing the Venturi effect.

[0012] Preferably, a connecting ring is fixedly connected to the top end of the feed pipe, a sealing ring is fixedly connected to the top end of the connecting ring, and mounting bolt holes are provided on the outer side wall of the connecting ring, so that the feed pipe can be quickly and sealed to the external feeding system, ensuring the airtightness of the entire feeding process.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] By combining the mixing tank with a multi-functional mixing mechanism, and driven by a single mixing motor, a planetary gear transmission mechanism consisting of a fixed gear ring and movable gears ingeniously enables the main stirring shaft to simultaneously drive the spiral conveyor blades and the high-speed dispersing disc to revolve, while also driving two sets of spiral scrapers to rotate in conjunction with the revolution. This achieves the synchronization and coordination of three mixing actions: wall scraping, conveying, and high-speed shearing. The two sets of spiral scrapers with the same spiral direction and complementary cleaning range ensure continuous scraping of the entire inner wall of the mixing tank without dead angles, effectively preventing material from sticking to the wall and charring, and promoting heat exchange. The upper spiral conveyor blades are responsible for forcibly pushing the material downwards, while the lower high-speed dispersing disc uses its surface dispersion holes to apply strong shearing and tearing action to the material. This upper and lower cooperation forms an efficient axial and radial circulating flow field, completely eliminating mixing dead angles. In addition, the Venturi tube integrated into the feed pipe achieves instantaneous dispersion and wetting of powder materials from the source, effectively avoiding the formation of "fish-eye" shaped powder clumps. The entire device has a compact structure and comprehensive functions, significantly improving mixing efficiency and uniformity, and is particularly suitable for mixing and processing high-viscosity food materials such as chocolate and candy.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figure 1-5 The illustrated material mixing device includes a mixing tank 1. A multi-functional mixing mechanism 2 is installed inside the mixing tank 1. The multi-functional mixing mechanism 2 includes a main stirring shaft 201 rotatably connected to the top wall of the mixing tank 1. A spiral conveying blade 202 is fixedly connected to the outer wall of the upper half of the main stirring shaft 201. A high-speed dispersing disc 203 is fixedly connected to the outer wall of the lower half of the main stirring shaft 201. Several sets of dispersing holes 204 are formed on the surface of the high-speed dispersing disc 203. Two sets of connecting frames 207 are fixedly connected to the outer wall of the main stirring shaft 201, located at the top and bottom of the main stirring shaft 201 respectively. Movable shafts 205 are rotatably connected to the two ends of the connecting frames 207. Spiral scrapers 206 are fixedly connected to the outer wall of the movable shafts 205. The cleaning ranges of the two sets of spiral scrapers 206 are complementary and their spiral directions are... Similarly, the main stirring shaft 201 integrates the upper spiral conveying blade 202, the lower high-speed dispersing disc 203, and the spiral scraper 206 driven by the connecting frame 207 and the movable shaft 205, realizing the combined functions of conveying, dispersing, and wall cleaning. The top of the mixing tank 1 is fixedly connected to the mounting frame 4, and the top wall of the mounting frame 4 is fixedly connected to the mixing motor 6. The mounting frame 4 provides a stable and reliable installation foundation for the mixing motor 6, ensuring the smoothness of power output. The output end of the mixing motor 6 is fixedly connected to the main stirring shaft 201. A discharge valve 3 is set below the main stirring shaft 201 and is installed at the bottom of the mixing tank 1, clarifying the direct driving relationship between the mixing motor 6 and the main stirring shaft 201. By setting the discharge valve 3 at the bottom of the tank, the controllable discharge of materials after mixing is realized.

[0025] Refer to the instruction manual appendix Figure 1-5A bracket mounting ring 7 is fixedly connected to the outer wall of the mixing tank 1, and a movable gear 8 is fixedly connected to the top of the movable shaft 205. The bracket mounting ring 7 enhances the structural stability and provides a prerequisite for the installation of the movable gear 8, which is the key structural foundation for realizing the rotational movement of the spiral scraper 206. A fixed gear ring 9 meshes with the outer wall of the movable gear 8. The fixed gear ring 9 is fixedly connected to the inner wall of the top of the mixing tank 1. The movable gear 8 rolls along the fixed gear ring 9, thereby forcing the movable shaft 205 to rotate. A feed pipe 11 is fixedly connected to the top of the mixing tank 1, and a Venturi tube 12 is fixedly connected to the inner wall of the feed pipe 11. The Venturi tube 12 is located inside the mixing tank 1, utilizing the Venturi effect to pre-mix the material at the moment of feeding. The feed pipe 11 is fixedly connected to a connecting ring 5 at its top end, and a sealing ring is fixedly connected to the top end of the connecting ring 5. The outer wall of the connecting ring 5 has mounting bolt holes 10, which allows the feed pipe 11 to be quickly and sealed to the external feeding system, ensuring the airtightness of the entire feeding process. Through the cooperation of the mixing tank 1 and the multi-functional mixing mechanism 2, and driven by a single mixing motor 6, the main stirring shaft 201 can drive the spiral conveying blades 202 and the high-speed dispersing disk 203 to revolve, while also driving the two sets of spiral scrapers 206 to rotate in conjunction with the revolution, thereby realizing the synchronization and coordination of the three mixing actions of wall scraping, conveying and high-speed shearing. Two sets of spiral scrapers 206, with the same spiral direction and complementary cleaning range, ensure continuous scraping of the entire inner wall of the mixing tank 1 without dead corners, effectively preventing material from sticking to the wall and charring, and promoting heat exchange. The upper spiral conveyor blades 202 are responsible for forcibly pushing the material downwards, while the lower high-speed dispersion disc 203 uses its surface dispersion holes 204 to apply strong shearing and tearing action to the material. This upper and lower cooperation forms an efficient axial and radial circulating flow field, completely eliminating mixing dead corners. In addition, the Venturi tube 12 integrated into the feed pipe 11 realizes instantaneous dispersion and wetting of powder materials from the source, effectively avoiding the formation of "fish-eye" powder clumps. The entire device has a compact structure, comprehensive functions, and significantly improves mixing efficiency and uniformity, making it particularly suitable for mixing and processing high-viscosity food materials such as chocolate and candy.

[0026] The working principle of this practical application is as follows:

[0027] Refer to the instruction manual appendix Figure 1-5During operation, the mixing motor 6 is started, and its output directly drives the main stirring shaft 201 to rotate. The main stirring shaft 201 then drives the spiral conveying blades 202, the high-speed dispersing disc 203, and the two sets of connecting frames 207 fixedly connected to its top and bottom to revolve around the main shaft axis. During the revolution, the movable shafts 205 installed at both ends of the connecting frames 207 also revolve, while the movable gear 8 fixed at the top of the movable shaft 205 meshes with the fixed gear ring 9 fixedly installed on the inner side wall of the top of the mixing tank 1. Under the action of gear meshing, the movable gear 8 is forced to roll along the fixed gear ring 9, thereby converting the revolution motion into the rotation of the movable shaft 205 itself. Finally, it drives the two sets of spiral scrapers 206 fixed on the movable shaft 205 to rotate while closely following the inner wall of the mixing tank 1, achieving efficient and continuous wall scraping and cleaning. During operation, the revolving spiral conveyor blades 202 primarily generate downward axial thrust, pushing the upper material towards the lower high-speed dispersion zone. The high-speed dispersion disc 203, which revolves and rotates at high speed, exerts strong shearing, impact, and dispersion effects on the flowing material through its dispersion holes 204. The dispersed material is recirculated under the influence of the flow field. When powdered material is fed through the feed pipe 11, the venturi tube 12 uses fluid dynamics to instantly disperse it before sending it into the mixing tank 1, directly entering the action area of ​​the high-speed dispersion disc 203 for further refinement and mixing. The entire mixing process achieves an organic combination of wall scraping, conveying, shearing, and circulation. Once the mixture is homogeneous, the material is discharged by activating the discharge valve 3 at the bottom of the mixing tank 1.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
