[0041] like Figure 1 and Figure 2 As shown, this embodiment provides a stirring device 100, which includes a main drive component 1, a main stirring component 2, an auxiliary drive component 3 and an auxiliary stirring component 4. The main drive component 1 and the auxiliary drive component 3 are both used to be fixed on a flavoring machine or a charging machine. The main stirring component 2 is connected to the main drive component 1, and the main drive component 1 drives the main stirring component 2 to rotate; the auxiliary stirring component 4 is connected to the auxiliary drive component 3, and the auxiliary drive component 3 drives the auxiliary stirring component 4 to rotate; the main stirring component 2 and the auxiliary stirring component 4 are both used to be partially inserted into a material tank 200 of the flavoring machine or the charging machine, and the ends extend to different height positions of 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 the feeding machine, and corresponding driving parts are set so that the main stirring component 2 and the auxiliary stirring component 4 can be rotated and stirred separately, thereby realizing three different stirring modes of only the main stirring component 2 rotating, only the auxiliary stirring component 4 rotating, and both the main stirring component 2 and the auxiliary stirring component 4 rotating, which has strong adaptability; when the main stirring component 2 and the auxiliary stirring component 4 are both rotating, since the ends of the main stirring component 2 and the auxiliary stirring component 4 extend to different height positions of the material tank 200, they can be fully stirred at different positions of the material tank 200, which greatly improves the stirring uniformity and stirring effect, and effectively improves the sedimentation and stratification problem of the material liquid.

[0043] It can be understood 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, so the rotation speeds of the main stirring component 2 and the auxiliary stirring component 4 can be adjusted according to the material liquid in the material tank 200.

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

[0045] Furthermore, the rotation center lines of the main stirring assembly 2 and the auxiliary stirring assembly 4 are collinear. By setting the rotation center lines of the main stirring assembly 2 and the auxiliary stirring assembly 4 to be collinear, it helps to promote the up and down circulation in the tank 200 and form a three-dimensional mixing flow field.

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

[0047] See also Figures 1 to 5 The main drive assembly 1 includes a main shaft support 11 and a main drive member 14 fixed to the main shaft support 11. The main shaft support 11 is used to be flange-connected to the material tank 200. The main stirring assembly 2 partially passes through the main shaft support 11 and is connected to the main drive member 14.

[0048] The main driving component 14 drives the main stirring assembly 2 to rotate. The main shaft support 11 is provided with a flange connection with the material tank 200, and the main driving component 14 is fixed on the main shaft support 11. 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 can be ensured to prevent leakage of the material liquid in the material tank 200.

[0049] Specifically, the top of the tank 200 is provided with a flange and a circular opening, the main shaft support 11 is cylindrical, the bottom end of the main shaft support 11 is connected to the flange at the top of the tank 200, and the main drive member 14 is fixed to the top of the main shaft support 11.

The stirring main shaft 21 is connected to the main drive assembly 1, and the main blade 24 is detachably fixed to the stirring main shaft 21 via the main connecting rod 23. The main blade 24 is detachably fixed to the stirring main shaft 21 via the main connecting rod 23, which not only facilitates maintenance and replacement of the main blade 24, but also helps to adjust the setting position of the main blade 24, thereby improving the applicability of the stirring device 100. Among them, the stirring main shaft 21 and the main drive member 14 can be connected by a flat 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. The inner rings of the upper cover 12 and the lower cover 13 are both provided with sealing rings. The sealing rings on the inner ring of the lower cover 13 are used to seal the gap between the outer side of the mixing main shaft 21 and the inner side of the main shaft support 11. The sealing rings on the inner ring of the upper cover 12 are used to seal the gap between the main drive member 14 and the main shaft support 11, as well as the gap between the main shaft support 11 and the flange connection of the tank 200. The sealing rings on the inner rings of the upper cover 12 and the lower cover 13 are both made of rubber; the upper cover 12 and the lower cover 13 are fixed to the main shaft support 11 by bolts.

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

[0053] Optionally, the main stirring assembly 2 further includes a main shaft sleeve 22, through which a main connecting rod 23 is fixed to the stirring main shaft 21. At least two main connecting rods 23 are arranged at intervals around the stirring main shaft 21, and the main paddles 24 are arranged in a one-to-one correspondence with the main connecting rods 23. By arranging the main shaft sleeve 22 on the stirring main shaft 21, multiple main connecting rods 23 are fixed circumferentially around the stirring main shaft 21, so that multiple main paddles 24 can be arranged accordingly, 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 member 14. The bottom end of the stirring spindle 21 is inserted into and fixedly connected to the spindle sleeve 22. When the stirring spindle 21 rotates, the spindle sleeve 22 rotates synchronously. The spindle sleeve 22 and the stirring spindle 21 can be fixed by screws.

[0055] In order to ensure the smooth rotation of the stirring shaft 21, the main stirring assembly 2 also includes bearings and seals. The stirring shaft 21 is rotatably connected to the main shaft support 11 through bearings. The seals include but are not limited to retaining rings for holes and retaining rings for shafts. Seals are often set in the bearing rotation connection. You can refer to the existing technology for setting, and will not go into details here.

[0056] Optionally, a sleeve cover 221 is embedded and fixed at the bottom end of the main shaft sleeve 22, and a sealing ring is provided at the inner ring of the sleeve cover 221 to prevent dust from entering the main shaft sleeve 22; the sealing ring at the inner ring of the sleeve 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, making it easy to adjust the installation 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. The main connecting rod 23 is provided in at least one group. The two main connecting rods 23 in the same group are symmetrically arranged relative to the stirring main shaft 21. Accordingly, the main blades 24 located on the main connecting rods 23 in the same group are also symmetrically arranged relative to the stirring main shaft 21. The spacing between the two main blades 24 ranges from 600 mm to 900 mm, including but not limited to 650 mm, 750 mm, and 850 mm.

[0059] In this embodiment, a connecting protrusion is provided at the top of the main paddle 24. The connecting protrusion has a threaded outer surface. The connecting protrusion passes through the mounting hole 231 and is threadedly connected to the nut. By securing the main paddle 24 with the nut, the main paddle 24 can be rotated by loosening the nut, causing the main paddle 24 to rotate within the mounting hole 231, thereby adjusting the setting angle of the main paddle 24.

[0060] The main connecting rod 23 extends horizontally, while the main paddle 24 is plate-shaped and extends vertically. The plane of the main paddle 24 intersects a vertical plane passing through the axis of the main connecting rod 23 at a predetermined angle, with the predetermined angle ranging from 30 to 60 degrees. The inclined main paddle 24 reduces energy consumption and promotes both axial and radial flow of the liquid during rotation, further enhancing the stirring effect.

[0061] Optionally, the corresponding preset angles of the two main blades 24 symmetrically arranged relative to the stirring main shaft 21 are equal (that is, the inclination angles remain consistent); the setting distance and inclination angle of the two main blades 24 need to be adjusted according to the characteristics of the material liquid in the material tank 200.

[0062] See also Figure 3 、 Figure 6 and Figure 7 The auxiliary stirring assembly 4 includes an auxiliary stirring shaft 41, an auxiliary connecting rod 43, and a defoaming blade 44. The auxiliary stirring shaft 41 is connected to the auxiliary driving assembly 3, and the defoaming blade 44 is fixed to the auxiliary stirring shaft 41 through the auxiliary connecting rod 43. By fixing the defoaming blade 44 to the auxiliary stirring shaft 41 through the auxiliary connecting rod 43, the rotation of the auxiliary stirring shaft 41 drives the defoaming blade 44 to rotate, thereby achieving a defoaming effect.

[0063] Specifically, the auxiliary drive assembly 3 includes an auxiliary shaft support 31, a coupling 32, and an auxiliary drive member 33. The bottom end of the auxiliary shaft support 31 is fixed to the top of the main drive member 14, and the auxiliary drive member 33 is fixed to the top of the auxiliary shaft support 31. The auxiliary drive member 33 is connected to the auxiliary stirring shaft 41 through the coupling 32. The auxiliary drive member 33 is a motor; the output shaft of the auxiliary drive member 33 and the auxiliary stirring 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 driving member 14 by bolts, and the flange surface of the auxiliary driving member 33 is fixed to the top end 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 coincides with that of the stirring auxiliary shaft 41; the stirring main shaft 21 and the stirring auxiliary shaft 41 are both 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 turn and is connected to the auxiliary drive member 33 through a coupling 32; the stirring auxiliary shaft 41 and the stirring main shaft 21 are rotatably connected through bearings, and the stirring auxiliary shaft 41 and the main shaft sleeve 22 are also rotatably connected through bearings to ensure that the stirring auxiliary shaft 41 remains stable during rotation; accordingly, seals are provided at the bearing installation positions, such as shaft retaining rings, hole retaining rings, etc., to prevent axial movement of the bearings.

[0066] In this embodiment, the auxiliary connecting rod 43 extends horizontally, the middle portion of the auxiliary connecting rod 43 is threadedly connected to the auxiliary shaft sleeve 42, and the 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, and the ends of the U-shaped defoaming blade 44 are connected to the auxiliary connecting rod 43, so that the defoaming blade 44 and the auxiliary connecting rod 43 enclose a through hole. The cross-section of the defoaming blade 44 is circular. The multiple defoaming blades 44 are symmetrically arranged relative to the auxiliary stirring shaft 41 and the auxiliary connecting rod 43. When the auxiliary stirring 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. In the vertical direction, the length of the auxiliary defoaming blade 44 is shorter than that of the main blade 24.

[0067] See also Figure 7 There are eight defoaming blades 44 , four of which are located at the left end of the auxiliary connecting rod 43 and the remaining four are located at the right end of the auxiliary connecting rod 43 .

[0068] See also Figure 8 and Figure 9The stirring device 100 further includes a temperature sensor 5, a frequency converter 6, and a controller 7. The temperature sensor 5 is fixed in the material tank 200 and is connected to the input terminal of the controller 7. The main drive component 1 and the auxiliary drive component 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 a temperature sensor 5, a frequency converter 6 and a controller 7, the temperature sensor 5 collects the temperature of the liquid in the material tank 200 in real time and transmits the temperature data signal to the controller 7. The controller 7 processes the temperature data signal and sends a control signal to the main drive component 1 and the auxiliary drive component 3 through the frequency converter 6, thereby accurately controlling the rotational speed of the main drive component 14 of the main drive component 1 and the auxiliary drive component 33 of the auxiliary drive component 3.

[0070] The following is a specific use process and control method of the stirring device 100:

[0071] Usage process: Turn on the main drive member 14 and the auxiliary drive member 33, drive the corresponding main blade 24 and the defoaming blade 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, by adjusting the rotation speed and rotation direction of the main blade 24 and the defoaming blade 44, a variety of cleaning modes can be achieved, such as general cleaning mode and enhanced cleaning mode. In terms of maintenance, it is necessary to regularly check the operating status of the main drive member 14 and the auxiliary drive member 33, including: motor temperature, noise, etc. If any abnormality is found, repair or replace them in time; it is necessary to regularly check whether the main blade 24 and the defoaming blade 44 are loose or worn, and if so, tighten or replace them in time.

[0072] Control method: After the material tank 200 of the flavoring machine or the feeding machine is filled with liquid, 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 and performs calculation and processing, and sends a control instruction to the frequency converter 6 through the output signal. The frequency converter 6 outputs a frequency signal to drive the main drive part 14 to operate. The motor output shaft of the main drive part 14 drives the main blade 24 to rotate. The initial speed is 20r / min. As the temperature of the liquid rises and reaches the set value, the speed drops to 13r / min. After the temperature of the liquid reaches the set value, the frequency converter 6 outputs a frequency signal to drive the auxiliary drive part 33 to operate. The auxiliary drive part 33 drives the defoaming blade 44 to start rotating, and the rotation direction is consistent with the main blade 24.

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

[0074] This embodiment is based on the principle of fluid flow. The stirring device 100 and the material tank 200 are connected by a flange to ensure the sealing of the material liquid and prevent leakage. Stirring is performed through the main stirring component 2 and the auxiliary stirring component 4, and different stirring speeds are set according to the temperature of the material liquid. The special main blade 24 and the defoaming blade 44 structure can fully stir the material liquid at different heights and positions in the material tank 200, forming a complex and efficient stirring flow field, greatly improving the stirring uniformity, and ensuring the stability of the stirring flow field of the material liquid in the material tank 200. Whether it is a low viscosity or a high viscosity material liquid, a good stirring effect can be achieved, and the problem of precipitation and foaming of the material liquid at the bottom of the material tank 200 is effectively solved.

[0075] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
