Description
Technical Field
[0001] This utility model relates to the field of mixer technology, specifically to a self-cleaning mixer with an automatic lifting cleaning nozzle. Background Technology
[0002] A disc mixer is a common piece of equipment used in dairy processing, primarily for homogenizing and mixing milk and other dairy products. Its working principle involves rotating discs generating strong shear force and turbulence, achieving a uniform mixture in a short time. A disc mixer typically consists of a mixing shaft, discs, and a housing. The mixing shaft drives the discs to rotate, and the interaction between the discs and the materials achieves efficient mixing. Disc mixers can evenly mix different dairy ingredients such as milk, cream, and sugar, ensuring consistent texture and taste. During the mixing process, high-temperature, short-time processing effectively kills bacteria, ensuring product hygiene and safety.
[0003] The authorization announcement number CN221889605U discloses a high-efficiency emulsifying tank for dairy products. According to its instruction manual and drawings, the second motor drives the second rotating shaft to rotate, the rotation of the second rotating shaft drives the turntable to rotate, the rotation of the turntable drives the push rod to rotate, thereby causing the connecting block on the connecting ring block to slide in the slide groove, and the push rod pushes the stirring rod to assist in completing the emulsification operation.
[0004] However, the solution has certain limitations: 1. For the inside of the emulsification tank, long-term stirring and emulsification inside the tank will inevitably leave some residue inside the tank. If it is not cleaned for a long time, it will inevitably affect the final taste of the dairy products. However, manually opening the tank for cleaning is inefficient. 2. How to ensure the self-cleaning function without affecting the normal emulsification function of the tank is also a problem that needs to be considered. Summary of the Invention
[0005] This invention addresses the problem of cleaning the inside of a disc mixer's tank by inventing a self-cleaning mixer with an automatically lifting cleaning nozzle. The water inside the cleaning nozzle flows from a large aperture to a small aperture, increasing the flow rate and the impact force on the inner wall of the emulsification tank. The cleaning nozzle then automatically cleans the inner wall of the emulsification tank. The automatic lifting design of the cleaning nozzle reduces downtime for cleaning.
[0006] The objective of this invention is achieved through the following technical solution: a self-cleaning mixer with an automatically lifting cleaning nozzle, comprising an emulsifying tank, a drive mechanism disposed on the top of the emulsifying tank, an end of the drive mechanism connected to a stirring drive shaft located inside the emulsifying tank, an end of the stirring drive shaft provided with a stirring assembly, a cleaning element placement component installed on the top of the emulsifying tank facing the inside of the emulsifying tank, a clearance groove provided at the bottom of the cleaning element placement component, a lifting cleaning nozzle disposed inside the cleaning element placement component, the lateral width of the clearance groove being greater than the lateral width of the cleaning nozzle, and the top of the cleaning nozzle connected to an external water inlet pipe.
[0007] Preferably, the interior of the cleaning element holder is hollow, the bottom of the cleaning nozzle is provided with a sealing cover plate that can block the clearance groove, the surface of the sealing cover plate is provided with a silicone ring, and the interior of the cleaning element holder is also provided with a lifting component for controlling the up and down movement of the cleaning nozzle.
[0008] Preferably, the cleaning nozzle includes a nozzle water pipe and a spherical nozzle. The spherical nozzle is hollow and has several water outlet holes on its surface. The top of the spherical nozzle is provided with a nozzle water pipe connected to the water inlet pipe.
[0009] Preferably, the lifting assembly includes a lifting support frame, a lifting drive shaft, a lifting guide rod, and a lifting slider. The cleaning element placement component has a lifting support frame inside, and the lifting support frame has a rotatable lifting drive shaft and lifting guide rod inside. The top of the lifting drive shaft is connected to a first drive motor, and the lifting guide rod has a slidable lifting slider. One side of the lifting slider is connected to the lifting drive shaft, and the other side of the lifting slider is connected to the side wall of the nozzle water pipe. The lifting drive shaft can drive the lifting slider to move up and down during rotation.
[0010] Preferably, the surface of the lifting drive shaft is provided with a threaded groove, and one side of the lifting slider is provided with an annular support plate. Both ends of the annular support plate are provided with snap-fit columns that fit into the threaded groove. This arrangement is to enable the lifting drive shaft to adjust the height of the lifting slider during rotation.
[0011] Preferably, the drive mechanism includes a motor support, a second drive motor, and a coupling. The motor support is mounted on the surface of the emulsifying tank, and the second drive motor is located above the motor support. The shaft of the second drive motor passes through the top of the motor support and is connected to one end of the coupling. The other end of the coupling is connected to the stirring drive shaft.
[0012] Preferably, the stirring assembly includes a sleeve and stirring blades. The surface of the stirring drive shaft is provided with a plurality of sleeves, and the surface of each sleeve is equipped with a plurality of stirring blades. This arrangement is to enable the stirring assembly to stir and emulsify the liquid.
[0013] Preferably, the emulsifying tank has a detachable tank cover on the top, a liquid inlet on the surface of the tank cover, and a liquid outlet at the bottom of the emulsifying tank. The positions of the liquid inlet and outlet are designed to effectively adapt to the connection with other process equipment during the production process.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. When water flows from the larger orifice to the smaller orifice inside the cleaning nozzle, the flow rate increases, resulting in greater impact force on the inner wall of the emulsification tank. The spherical nozzle then automatically cleans the inner wall of the emulsification tank. The precise spray design of the spherical nozzle's outlet holes also optimizes water usage, saving water resources, reducing scaling and corrosion to extend equipment lifespan, and improving the final taste of dairy products.
[0016] 2. The spherical nozzle utilizes a lifting assembly for automatic lifting, reducing downtime for cleaning and improving the continuous operation capability of the production line. It minimizes manual intervention, increases cleaning efficiency, and is particularly suitable for high-hygiene-standard scenarios such as dairy products; it also reduces the risk of residual contamination.

[0023] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:
[0024] like Figure 1 and Figure 2 As shown, a self-cleaning mixer with an automatic lifting cleaning nozzle includes an emulsifying tank 1. The top of the emulsifying tank 1 is provided with a detachable tank cover 11. The surface of the tank cover 11 is provided with a liquid inlet 12, and the bottom of the emulsifying tank 1 is provided with a liquid outlet 13.
[0025] Milk liquid that needs to be mixed evenly, refined into fine particles, and improved in taste and stability enters the interior of mixing tank 1 through material inlet 12. After the material is mixed evenly in mixing tank 1, it is discharged through material outlet 13. The positions of material inlet 12 and material outlet 13 are designed to effectively adapt to the connection with other process equipment in the production process.
[0026] Please continue to refer to this. Figure 5 A drive mechanism 2 is installed at the top of the emulsification tank 1. The end of the drive mechanism 2 is connected to a stirring drive shaft 3 located inside the emulsification tank 1. The end of the stirring drive shaft 3 is provided with a stirring assembly 4.
[0027] The drive mechanism 2 includes a motor support 21, a second drive motor 22, and a coupling 23. The motor support 21 is mounted on the surface of the emulsification tank 1. The second drive motor 22 is located above the motor support 21. The shaft of the second drive motor 22 passes through the top of the motor support 21 and is connected to one end of the coupling 23. The other end of the coupling 23 is connected to the stirring drive shaft 3.
[0028] The shaft of the second drive motor 22 can drive the coupling 23 to rotate during rotation, and the coupling 23 can simultaneously drive the stirring drive shaft 3 to rotate during rotation. When the drive mechanism 4 is disassembled, repaired or cleaned from the stirring drive shaft 3 connected to the end, it is only necessary to remove the locking bolts between the tank cover 11 and the top of the emulsification tank 1, and then use an external crane to lift it up and place it in the designated position.
[0029] The stirring assembly 4 includes a sleeve 41 and stirring blades 42. The surface of the stirring drive shaft 3 is provided with a plurality of sleeves 41, and a plurality of stirring blades 42 are installed on the surface of each sleeve 41.
[0030] The sleeve 41 and the stirring blade 42 rotate along with the stirring drive shaft 3. During the high-speed rotation of the stirring blade 42, a strong velocity difference is generated between the blade edge and the material, forming a high shear force region. This shear force can break up fat globules or protein particles, while also disrupting the laminar boundary layer of the fluid, promoting micro-mixing.
[0031] It should be noted that the axis of the stirring drive shaft 3 is not on the same axis as the axis of the emulsifying tank 1. This setting makes the entire mixer a disc mixer. Disc mixers have significant advantages in scenarios requiring high uniformity and high stability of dairy products due to their strong shear force design and multi-directional mixing capabilities, while ordinary mixers are more suitable for basic mixing tasks.
[0032] Please continue to refer to this. Figure 3 and Figure 4 The top of the emulsification tank 1 is equipped with a cleaning element placement component 5 facing the inside of the emulsification tank 1. The bottom of the cleaning element placement component 5 is provided with a clearance groove 51. The interior of the cleaning element placement component 5 is provided with a cleaning nozzle 6 that can be raised and lowered. The lateral width of the clearance groove 51 is greater than the lateral width of the cleaning nozzle 6. The top of the cleaning nozzle 6 is connected to an external water inlet pipe 7.
[0033] In this embodiment, the interior of the cleaning element placement component 5 is hollow, and the bottom of the cleaning nozzle 6 is provided with a sealing cover plate 61 that can block the clearance groove 51. The surface of the sealing cover plate 61 is provided with a silicone ring 611. The interior of the cleaning element placement component 5 is also provided with a lifting component 8 for controlling the up and down movement of the cleaning nozzle 6.
[0034] The cleaning nozzle 6 includes a nozzle water pipe 62 and a spherical nozzle 63. The spherical nozzle 63 is hollow and has several water outlet holes 631 on its surface. The top of the spherical nozzle 63 is provided with a nozzle water pipe 62 connected to the water inlet pipe 7.
[0035] With this setup, when the emulsification tank 1 is no longer undergoing emulsification and stirring, as the cleaning nozzle 6 moves downwards, the top of the sealing cover 61 and the bottom of the clearance groove 51 gradually open, exposing the spherical nozzle 63 inside the emulsification tank 1. During the downward movement of the cleaning nozzle 6, the nozzle water pipe 62 slides relative to the side wall of the water inlet pipe 7, while the water inlet pipe 7 remains stationary.
[0036] After the cleaning nozzle 6 is positioned, external water flows sequentially through the inlet pipe 7 and the nozzle water pipe 62 before exiting from the spherical nozzle 63. When the flow rates of the inlet pipe 7 and the nozzle water pipe 62 remain constant, the water inside the cleaning nozzle 6 flows from the large orifice to the small orifice, resulting in an increased flow velocity and a greater impact force on the inner wall of the emulsification tank 1. At this time, the spherical nozzle 63 can automatically clean the inner wall of the emulsification tank 1. The precise spray design of the water outlet 631 of the spherical nozzle 63 also optimizes water consumption and saves water resources, not only reducing scaling and corrosion to extend equipment life, but also improving the final taste of dairy products.
[0037] In this embodiment, the lifting assembly 8 includes a lifting support frame 81, a lifting transmission shaft 82, a lifting guide rod 83, and a lifting slider 84. The cleaning element placement component 5 has a lifting support frame 81 inside. The lifting support frame 81 has a rotatable lifting transmission shaft 82 and lifting guide rod 83 inside. The top of the lifting transmission shaft 82 is connected to a first drive motor 85. The lifting guide rod 83 has a slidable lifting slider 84. One side of the lifting slider 84 is connected to the lifting transmission shaft 82, and the other side of the lifting slider 84 is connected to the side wall of the nozzle water pipe 62. The lifting transmission shaft 82 can drive the lifting slider 84 to move up and down during rotation. The surface of the lifting transmission shaft 82 has a threaded groove 821. One side of the lifting slider 84 has an annular support plate 841. Both ends of the annular support plate 841 have snap-fit posts 842 that fit the threaded groove 821.
[0038] When it is necessary to control the cleaning nozzle 6 to move up and down, the shaft of the first drive motor 85 drives the lifting transmission shaft 82 to rotate. During the rotation of the lifting transmission shaft 82, the trajectory of the threaded groove 821 of the lifting transmission shaft 82 can guide the locking column 842, so that the locking column 842 drives the entire lifting slider 84 to move up or down. During the movement of the lifting slider 84, the lifting guide rod 83 plays a supporting and guiding role.
[0039] The automatic lifting design of the entire spherical nozzle 63 reduces downtime for cleaning and improves the continuous operation capability of the production line. It reduces manual intervention, improves cleaning efficiency, and is especially suitable for high hygiene standards scenarios such as dairy products; it also reduces the risk of residual contamination and meets food-grade equipment hygiene standards.
[0040] Working principle and usage of this utility model:
[0041] Liquid milk enters the mixing tank 1 through the feed inlet 12. The drive motor 42's shaft rotates, driving the coupling 43 to rotate. Simultaneously, the coupling 43 drives the transmission shaft 2. The sleeve 31 and the stirring blades 32 rotate along with the transmission shaft 2. During high-speed rotation, the stirring blades 32 create a strong velocity difference between the blade edges and the material, forming a high-shear force zone. This shear force can break up particle clusters (such as fat globules or protein particles) and disrupt the laminar boundary layer, promoting micro-mixing.
[0042] When the emulsification tank 1 is no longer being stirred, the shaft of the first drive motor 85 drives the lifting transmission shaft 82 to rotate. During the rotation of the lifting transmission shaft 82, the trajectory of the threaded groove 821 of the lifting transmission shaft 82 can guide the locking column 842, so that the locking column 842 drives the entire lifting slider 84 to move downward. During the downward movement of the cleaning nozzle 6, the top of the sealing cover plate 61 and the bottom of the relief groove 51 gradually open, so that the spherical nozzle 63 is exposed inside the emulsification tank 1.
[0043] After the cleaning nozzle 6 is positioned, external water flows sequentially through the inlet pipe 7 and the nozzle water pipe 62 before exiting from the spherical nozzle 63. When the flow rates of the inlet pipe 7 and the nozzle water pipe 62 remain constant, the water inside the cleaning nozzle 6 flows from the large orifice to the small orifice, resulting in an increased flow velocity and a greater impact force on the inner wall of the emulsification tank 1. At this time, the spherical nozzle 63 can automatically clean the inner wall of the emulsification tank 1. The precise spray design of the water outlet 631 of the spherical nozzle 63 also optimizes water consumption and saves water resources, not only reducing scaling and corrosion to extend equipment life, but also improving the final taste of dairy products.
