It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0038] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0041] As shown in Figures 1 and 2, this embodiment provides a stirring device 100, which includes a main drive assembly 1, a main stirring assembly 2, an auxiliary drive assembly 3, and an auxiliary stirring assembly 4. The main drive assembly 1 and the auxiliary drive assembly 3 are both fixed on a fragrance adder or a feeder. The main stirring assembly 2 is connected to the main drive assembly 1, and the main drive assembly 1 drives the main stirring assembly 2 to rotate. The auxiliary stirring assembly 4 is connected to the auxiliary drive assembly 3, and the auxiliary drive assembly 3 drives the auxiliary stirring assembly 4 to rotate. The main stirring assembly 2 and the auxiliary stirring assembly 4 are both partially inserted into the material tank 200 of the fragrance adder or the feeder, and their ends extend to different height positions in the material tank 200.

[0042] The main stirring component 2 and the auxiliary stirring component 4 are inserted into the material tank 200 of the flavoring machine or feeder, and corresponding driving components are provided so that the main stirring component 2 and the auxiliary stirring component 4 can rotate and stir independently. This allows for three different stirring modes: only the main stirring component 2 rotates, only the auxiliary stirring component 4 rotates, and both the main stirring component 2 and the auxiliary stirring component 4 rotate, providing strong adaptability. When both the main stirring component 2 and the auxiliary stirring component 4 rotate, since their ends extend to different heights in the material tank 200, they can be fully stirred at different positions in the material tank 200, greatly improving the uniformity and effect of stirring and effectively improving the problem of sedimentation and stratification of the liquid.

[0043] It is understandable that the main drive component 1 can drive the main stirring component 2 to rotate at different speeds, and the auxiliary drive component 3 can drive the auxiliary stirring component 4 to rotate at different speeds. Therefore, the rotation speed of the main stirring component 2 and the auxiliary stirring component 4 can be adjusted according to the liquid in the material tank 200.

[0044] Specifically, the end of the main stirring component 2 is located in the middle of the material tank 200, and the end of the auxiliary stirring component 4 is located at the bottom of the material tank 200. The main stirring component 2 is used to stir the middle of the material tank 200, and the auxiliary stirring component 4 is used to stir the bottom of the material tank 200. The combination forms a complex and efficient stirring flow field, resulting in a more uniform stirring effect and preventing the liquid from settling at the bottom of the material tank 200.

[0045] Furthermore, the rotation center lines of the main stirring component 2 and the auxiliary stirring component 4 are collinear. By setting the rotation center lines of the main stirring component 2 and the auxiliary stirring component 4 to be collinear, it helps to promote the vertical circulation within the material tank 200, forming a three-dimensional mixing flow field.

[0046] In this embodiment, the material tank 200 is cylindrical, and the rotation center lines of the main stirring component 2 and the auxiliary stirring component 4 are collinear and coincide with the center line of the material tank 200. In other embodiments, the rotation center lines of the main stirring component 2 and the auxiliary stirring component 4 may be set parallel and spaced apart, and the specific positions of the main stirring component 2 and the auxiliary stirring component 4 may be set according to the actual material tank 200.

[0047] Referring to Figures 1 to 5, the main drive assembly 1 includes a main shaft support 11 and a main drive component 14 fixed to the main shaft support 11. The main shaft support 11 is used to connect to the flange of the material tank 200. The main stirring assembly 2 partially passes through the main shaft support 11 and is connected to the main drive component 14.

[0048] The main driving component 14 drives the main stirring assembly 2 to rotate. The main driving component 14 is fixed on the main shaft support 11 by connecting the main shaft support 11 to the flange of the material tank 200. The main stirring assembly 2 partially passes through the main shaft support 11 and is connected to the main driving component 14, so that the main driving component 14 can be placed outside the material tank 200 and the main stirring assembly 2 can be inserted into the material tank 200. At the same time, the sealing of the connection between the stirring device 100 and the material tank 200 is guaranteed to prevent the material liquid in the material tank 200 from leaking.

[0049] Specifically, the top of the material tank 200 is provided with a flange and has a circular opening. The main shaft support 11 is cylindrical, and the bottom end of the main shaft support 11 is connected to the top flange of the material tank 200. The main drive component 14 is fixed to the top of the main shaft support 11. In this embodiment, the main drive component 14 is a motor with a reducer, and the reducer flange face of the main drive component 14 is connected to the top end face of the main shaft support 11 by bolts.

[0050] Furthermore, the main stirring assembly 2 includes a stirring main shaft 21, a main connecting rod 23, and a main impeller 24. The stirring main shaft 21 is connected to the main drive assembly 1, and the main impeller 24 is detachably fixed to the stirring main shaft 21 via the main connecting rod 23. Detachably fixing the main impeller 24 to the stirring main shaft 21 via the main connecting rod 23 facilitates maintenance and replacement of the main impeller 24 and also helps adjust the position of the main impeller 24, improving the applicability of the stirring device 100. The stirring main shaft 21 and the main drive assembly 14 can be connected via a key to transmit power.

[0051] In this embodiment, the main drive assembly 1 further includes an upper cover 12 and a lower cover 13. The upper cover 12 is embedded and fixed in the top end of the main shaft support 11, and the lower cover 13 is embedded and fixed in the bottom end of the main shaft support 11. Sealing rings are provided at the inner rings of both the upper cover 12 and the lower cover 13. The sealing ring at the inner ring of the lower cover 13 is used to seal the gap between the outer side of the stirring main shaft 21 and the inner side of the main shaft support 11. The sealing ring at the inner ring of the upper cover 12 is used to seal the gap at the connection between the main drive component 14 and the main shaft support 11, as well as the gap at the connection between the main shaft support 11 and the flange of the material tank 200. The sealing rings at the inner rings of both the upper cover 12 and the lower cover 13 are made of rubber. The upper cover 12 and the lower cover 13 are fixed to the main shaft support 11 by bolts.

[0052] By setting the upper cover 12, the lower cover 13 and the corresponding sealing ring, dust or oil can be prevented from entering the spindle support 11 or the material tank 200.

[0053] Optionally, the main stirring assembly 2 further includes a main shaft sleeve 22. The main connecting rods 23 are fixed to the stirring main shaft 21 via the main shaft sleeve 22. At least two main connecting rods 23 are spaced apart around the stirring main shaft 21, and the main impellers 24 are correspondingly arranged one-to-one with each main connecting rod 23. By setting the main shaft sleeve 22 on the stirring main shaft 21, multiple main connecting rods 23 are fixed around the stirring main shaft 21, allowing for the corresponding arrangement of multiple main impellers 24, which helps to improve stirring efficiency.

[0054] In this embodiment, the stirring spindle 21 extends vertically; the top end of the stirring spindle 21 passes through the spindle support 11 and is connected to the main drive component 14, and the bottom end of the stirring spindle 21 is inserted into the spindle sleeve 22 and fixedly connected to the spindle sleeve 22. When the stirring spindle 21 rotates, it drives the spindle sleeve 22 to rotate synchronously. The spindle sleeve 22 and the stirring spindle 21 can be fixed together with screws.

[0055] To ensure the smooth rotation of the stirring spindle 21, the main stirring assembly 2 also includes bearings and seals. The stirring spindle 21 and the spindle support 11 are rotatably connected by bearings. The seals include, but are not limited to, retaining rings for holes and retaining rings for shafts. Seals are often installed in the rotating connection of bearings, and can be set according to existing technology, so they will not be described in detail here.

[0056] Optionally, a bushing cover 221 is embedded and fixed at the bottom end of the spindle bushing 22. A sealing ring is provided at the inner ring of the bushing cover 221 to prevent dust from entering the spindle bushing 22. The sealing ring at the inner ring of the bushing cover 221 is made of rubber.

[0057] Furthermore, the main connecting rod 23 is provided with at least three mounting holes 231, and the main blade 24 is detachably fixed through one of the mounting holes 231. By providing at least three mounting holes 231 on the main connecting rod 23, the main blade 24 can be detachably fixed to one of the mounting holes 231, which facilitates adjusting the setting position of the main blade 24 according to actual needs.

[0058] In this embodiment, the main shaft sleeve 22 is threadedly connected to the main connecting rod 23. At least one set of main connecting rods 23 is provided, with two main connecting rods 23 in the same set symmetrically arranged relative to the stirring main shaft 21. Correspondingly, the main impellers 24 located on the same set of main connecting rods 23 are also symmetrically arranged relative to the stirring main shaft 21. The distance between the two main impellers 24 ranges from 600mm to 900mm, including but not limited to 650mm, 750mm, and 850mm.

[0059] In this embodiment, the main blade 24 has a connecting protrusion at its top end, and the outer surface of the connecting protrusion is threaded. The connecting protrusion passes through the mounting hole 231 and is threadedly connected to the nut. The main blade 24 is fixed by the nut, and when the nut is loosened, the main blade 24 can be rotated, causing the main blade 24 to rotate within the mounting hole 231, thereby adjusting the setting angle of the main blade 24.

[0060] The main connecting rod 23 extends horizontally, while the main impeller 24 is plate-shaped and extends vertically. The plane containing the main impeller 24 intersects the vertical plane passing through the axis of the main connecting rod 23 at a preset angle, which ranges from 30 to 60 degrees. By setting the main impeller 24 at an angle, energy consumption can be reduced, and the material will flow axially and radially simultaneously during rotation, further improving the mixing effect.

[0061] Optionally, the two main blades 24 symmetrically arranged relative to the stirring shaft 21 have the same preset included angle (i.e., the tilt angle is consistent); the setting distance and tilt angle of the two main blades 24 need to be adjusted according to the characteristics of the liquid in the tank 200.

[0062] Referring to Figures 3, 6, and 7, the auxiliary stirring assembly 4 includes a stirring auxiliary shaft 41, an auxiliary connecting rod 43, and a defoaming impeller 44. The stirring auxiliary shaft 41 is connected to the auxiliary drive assembly 3, and the defoaming impeller 44 is fixed to the stirring auxiliary shaft 41 via the auxiliary connecting rod 43. By fixing the defoaming impeller 44 to the stirring auxiliary shaft 41 via the auxiliary connecting rod 43, the rotation of the stirring auxiliary shaft 41 drives the defoaming impeller 44 to rotate, thereby achieving the defoaming effect.

[0063] Specifically, the auxiliary drive assembly 3 includes an auxiliary shaft support 31, a coupling 32, and an auxiliary drive component 33. The bottom end of the auxiliary shaft support 31 is fixed to the top end of the main drive component 14, and the auxiliary drive component 33 is fixed to the top end of the auxiliary shaft support 31. The auxiliary drive component 33 is connected to the stirring auxiliary shaft 41 via the coupling 32. The auxiliary drive component 33 is a motor. The output shaft of the auxiliary drive component 33 and the stirring auxiliary shaft 41 are connected by a flat key to transmit power.

[0064] In this embodiment, the bottom end of the auxiliary shaft support 31 is fixed to the top flange surface of the main drive component 14 by bolts, and the flange surface of the auxiliary drive component 33 is fixed to the top of the auxiliary shaft support 31 by bolts.

[0065] In this embodiment, the stirring main shaft 21 is a hollow shaft, and the axial direction of the stirring main shaft 21 and the stirring auxiliary shaft 41 coincides. Both the stirring main shaft 21 and the stirring auxiliary shaft 41 are made of stainless steel. The top end of the stirring auxiliary shaft 41 passes through the main shaft sleeve 22 and the stirring main shaft 21 in sequence and is connected to the auxiliary drive component 33 through the coupling 32. The stirring auxiliary shaft 41 and the stirring main shaft 21 are rotatably connected by bearings, and the stirring auxiliary shaft 41 and the main shaft sleeve 22 are also rotatably connected by bearings to ensure that the stirring auxiliary shaft 41 remains stable during rotation. Correspondingly, sealing components, such as shaft retaining rings and hole retaining rings, are provided at the bearing mounting positions to prevent axial movement of the bearings.

[0066] In this embodiment, the auxiliary connecting rod 43 extends horizontally, and its middle part is threadedly connected to the auxiliary shaft sleeve 42. The two ends of the auxiliary connecting rod 43 are symmetrically arranged relative to the auxiliary shaft sleeve 42. The defoaming blade 44 is welded to the auxiliary connecting rod 43. The defoaming blade 44 is U-shaped, with both ends connected to the auxiliary connecting rod 43, so that the defoaming blade 44 and the auxiliary connecting rod 43 enclose a through hole. The defoaming blade 44 has a circular cross-section. Multiple defoaming blades 44 are symmetrically arranged relative to the stirring auxiliary shaft 41 and symmetrically arranged relative to the auxiliary connecting rod 43. When the stirring auxiliary shaft 41 rotates, it drives the defoaming blades 44 to rotate at the bottom of the material tank 200, stirring the liquid at the bottom of the material tank 200. Furthermore, in the vertical direction, the length of the auxiliary defoaming blade 44 is less than the length of the main blade 24.

[0067] Referring to Figure 7, there are 8 defoaming blades 44, 4 of which are located at the left end of the auxiliary connecting rod 43 and the remaining 4 are located at the right end of the auxiliary connecting rod 43.

[0068] Referring to Figures 8 and 9, the stirring device 100 also includes a temperature sensor 5, a frequency converter 6, and a controller 7. The temperature sensor 5 is fixed inside the material tank 200 and is connected to the input terminal of the controller 7. The main drive assembly 1 and the auxiliary drive assembly 3 are both connected to the output terminal of the controller 7 via the frequency converter 6. The controller 7 is a programmable logic controller (PLC).

[0069] By setting temperature sensor 5, frequency converter 6 and controller 7, temperature sensor 5 collects the temperature of the liquid in the tank 200 in real time and transmits the temperature data signal to controller 7. Controller 7 processes the temperature data signal and sends control signals to main drive assembly 1 and auxiliary drive assembly 3 through frequency converter 6, thereby accurately controlling the rotation speed of main drive component 14 of main drive assembly 1 and auxiliary drive component 33 of auxiliary drive assembly 3.

[0070] The following are the specific usage procedures and control methods of the stirring device 100:

[0071] Usage: Turn on the main drive unit 14 and auxiliary drive unit 33 to drive the corresponding main impeller 24 and defoaming impeller 44 to rotate and control the rotation speed. The rotation speed can be adjusted within the range of 13r / min-20r / min according to the characteristics of the liquid and the stirring requirements. When cleaning the tank 200, various cleaning modes can be achieved by adjusting the rotation speed and direction of the main impeller 24 and defoaming impeller 44, such as general cleaning mode and enhanced cleaning mode. For maintenance, the operating status of the main drive unit 14 and auxiliary drive unit 33 should be checked regularly, including motor temperature and noise. If any abnormalities are found, repair or replace them promptly. The main impeller 24 and defoaming impeller 44 should also be checked regularly for looseness or wear. If any are found, tighten or replace them promptly.

[0072] Control Method: After the liquid filling tank 200 of the flavoring machine or feeder is completed, the temperature sensor 5 collects the temperature of the liquid in real time and transmits the data to the controller 7. The controller 7 receives the temperature data signal of the liquid, performs calculations and processing, and sends control commands to the frequency converter 6 through the output signal. The frequency converter 6 outputs a frequency signal to drive the main drive component 14 to operate. The motor output shaft of the main drive component 14 drives the main blade 24 to rotate. The initial speed is 20 r / min. As the liquid temperature rises to the set value, the speed decreases to 13 r / min. After the liquid temperature reaches the set value, the frequency converter 6 outputs a frequency signal to drive the auxiliary drive component 33 to operate. The auxiliary drive component 33 drives the defoaming blade 44 to start rotating, and the rotation direction is consistent with that of the main blade 24.

[0073] During cleaning of the material tank 200, various cleaning modes can be set by adjusting the rotation speed and direction of the main impeller 24 and the defoaming impeller 44, such as a general cleaning mode and an enhanced cleaning mode. In the general cleaning mode, the main impeller 24 and the defoaming impeller 44 rotate at a low speed and in the same direction; in the enhanced cleaning mode, the main impeller 24 and the defoaming impeller 44 rotate at a high speed and in opposite directions.

[0074] Based on the principle of fluid flow, this embodiment uses a flange connection between the stirring device 100 and the tank 200 to ensure the sealing of the liquid and prevent leakage. Stirring is performed by the main stirring component 2 and the auxiliary stirring component 4. Different stirring speeds are set according to the temperature of the liquid, and the special structure of the main impeller 24 and the defoaming impeller 44 can fully stir the liquid at different heights and positions in the tank 200, forming a complex and efficient stirring flow field. This greatly improves the uniformity of stirring and ensures the stability of the stirring flow field in the tank 200. Good stirring effect can be achieved for liquids with low or high viscosity, and the problem of sedimentation and foaming at the bottom of the tank 200 is effectively solved.

[0075] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
