[0037] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0038] As described above, there is a problem of poor connection stability between the stirring member and the connecting sleeve of some stirring mechanisms, which affects the stirring efficiency.

[0039] Taking the stirring mechanism in the sewage treatment equipment of the cigarette production system as an example for illustration.

[0040] During the cigarette production process, it is usually necessary to use sewage treatment equipment to treat sewage. That is to say, sewage treatment equipment is usually provided in the tobacco production system to treat cigarette sewage.

[0041] Figure 1 The structure of the sewage treatment equipment and its stirring mechanism in the related art is shown.

[0042] See Figure 1 , the sewage treatment equipment 100 includes a water tank 20 and a stirring mechanism 10. The water tank 20 is used to hold sewage. During the sewage treatment process, sewage treatment agents such as polyaluminum chloride PAC and polyacrylamide PAM are usually added to the sewage in the water tank 20. These sewage treatment agents are used to promote the precipitation of suspended solids in the sewage to purify the sewage, which is one of the key steps in cigarette sewage treatment. The stirring mechanism 10 is used to stir the sewage added with sewage treatment agents in the water tank 20 so that the sewage treatment agents are fully dissolved in the sewage, thereby achieving a better purification effect.

[0043] Among them, see Figure 1 , the stirring mechanism 10 includes a motor 1, a connecting sleeve 2 and a stirring member 3. The connecting sleeve 2 is used to connect the motor 1 and the stirring member 3. It connects the motor 1 and is sleeved outside the stirring member 3, so that the motor 1 can drive the stirring member 3 to rotate through the connecting sleeve 2 to achieve the stirring function.

[0044] As Figure 1 shown, in the related art, the connecting sleeve 2 and the stirring member 3 are connected and fixed by two screws 6. Both screws 6 extend into the connecting sleeve 2 through the side wall of the connecting sleeve 2 and abut against the side surface of the stirring member 3 to achieve the connection and fixation between the stirring member 3 and the connecting sleeve 2. In this case, the screws 6 only abut against the side surface of the stirring member 3, and the connection stability between the stirring member 3 and the connecting sleeve 2 is poor. The stirring member 3 is easily detached, resulting in poor structural reliability of the stirring mechanism 10 and affecting the stirring efficiency.

[0045] It can be seen that in the stirring mechanism 10 in the related art, there is a problem of poor connection stability between the stirring member 3 and the connecting sleeve 2, which affects the stirring efficiency.

[0046] In view of the above situation, the present application improves the structure of the stirring mechanism 10 to improve the stirring efficiency by enhancing the connection stability between the stirring member 3 and the connecting sleeve 2.

[0047] Figure 2 The structure of the stirring mechanism 10 in the present application is exemplarily shown.

[0048] See Figure 2, in the present application, the stirring mechanism 10 includes a motor 1, a stirring member 3, a connecting sleeve 2, and a connecting member 4. The connecting sleeve 2 is connected to the motor 1 and sleeved on the stirring member 3. A connecting hole 22 is provided on the side wall of the connecting sleeve 2. The stirring member 3 has a through hole 31. The connecting member 4 passes through the connecting hole 22 and the through hole 31 to pass through the connecting sleeve 2 and the stirring member 3, so as to connect the stirring member 3 and the connecting sleeve 2.

[0049] Based on the above settings, the stirring member 3 and the connecting sleeve 2 are no longer connected by a screw 6 passing through the connecting sleeve 2 and abutting against the side surface of the stirring member 3, but are connected by a connecting member 4 passing through the connecting sleeve 2 and the stirring member 3. Since the contact area between the connecting member 4 passing through the stirring member 3 and the stirring member 3 is larger than that of the screw 6 abutting against the side surface of the stirring member 3, and the connection firmness is stronger. Therefore, the connection stability between the stirring member 3 and the connecting sleeve 2 can be effectively improved, and further, the risk of the stirring member 3 falling off can be effectively reduced, the structural reliability of the stirring mechanism 10 can be improved, and the stirring efficiency can be enhanced.

[0050] It can be seen that by providing a connecting member 4 that not only passes through the connecting hole 22 on the side wall of the connecting sleeve 2 but also passes through the through hole 31 on the stirring member 3 to connect the connecting sleeve 2 and the stirring member 3, the connection stability between the stirring member 3 and the connecting sleeve 2 can be effectively improved, the risk of the stirring member 3 falling off can be reduced, the structural reliability of the stirring mechanism 10 can be improved, and the stirring efficiency can be enhanced.

[0051] Among them, the connecting hole 22 can be provided only on one side wall of the connecting sleeve 2. In this case, after the connecting member 4 passes through the stirring member 3, it does not pass through the other side of the connecting sleeve 2 but is located inside the connecting sleeve 2. In this case, since the connecting member 4 passes through the stirring member 3, compared with the case in the related art where the screw 6 only abuts against the side surface of the stirring member 3 and does not pass through the stirring member 3, the connection stability between the stirring member 3 and the connecting sleeve 2 can also be improved, and further, the stirring efficiency can be enhanced.

[0052] Or, as a variant, see Figure 2, the connecting holes 22 can also be arranged on the opposite side walls of the connecting sleeve 2, so that the connecting holes 22 are provided on both opposite side walls of the connecting sleeve 2, and the connecting member 4 passes through the connecting holes 22 on the opposite side walls of the connecting sleeve 2 to pass through the opposite side walls of the connecting sleeve 2. In this case, after the connecting member 4 passes through the stirring member 3, it is not located inside the connecting sleeve 2, but does not pass through the other side of the connecting sleeve 2 and extends to the outside of the connecting sleeve 2. On the one hand, since the connecting member 4 passes through the stirring member 3, compared with the case in the related art where the screw 6 only abuts against the side of the stirring member 3 and does not pass through the stirring member 3, the connection stability between the stirring member 3 and the connecting sleeve 2 can be improved, and the stirring efficiency can be enhanced. On the other hand, since the connecting member 4 not only passes through the stirring member 3, but also passes through the connecting sleeve 2, compared with the case where the connecting member 4 is located in the connecting sleeve 2 and does not pass through the connecting sleeve 2 and the case in the related art where the screw 6 is located in the connecting sleeve 2 and abuts against the side of the stirring member 3, it also has the characteristics of large working space and convenient disassembly and assembly. In this way, the difficulty of disassembly, installation and maintenance can be reduced, the efficiency of disassembly, installation and maintenance can be improved, the manpower required for disassembly, installation and maintenance can be reduced, and it is convenient to carry out disassembly, installation and maintenance without the cooperation of multiple people.

[0053] It can be seen that arranging the connecting holes 22 on both opposite side walls of the connecting sleeve 2 and making the connecting member 4 pass through the connecting holes 22 on both opposite side walls of the connecting sleeve 2 can not only improve the connection stability between the stirring member 3 and the connecting sleeve 2, enhance the stirring efficiency, but also reduce the difficulty of disassembly, installation and maintenance and improve the efficiency of disassembly, installation and maintenance.

[0054] In the foregoing embodiments, the connecting member 4 can adopt various structural forms, as long as it can pass through the stirring member 3 and connect and fix the stirring member 3 and the connecting sleeve 2. As one of them, see Figure 2 , the connecting member 4 includes a bolt 41 and a nut 42. The bolt 41 passes through the connecting sleeve 2 and the stirring member 3, and the nut 42 is screwed onto the bolt 41. In this way, not only the structure is simple, but also the disassembly and assembly are convenient, and at the same time, the connection firmness is relatively strong.

[0055] Among them, the number of nuts 42 in the connecting member 4 is not limited, and can be one, two or more (that is, three or more). For example, see Figure 2 , in some embodiments, the connecting member 4 includes two nuts 42, and these two nuts 42 are sleeved on the same bolt 41. Since the two nuts 42 can better fasten and prevent loosening, the connection stability between the stirring member 3 and the connecting sleeve 2 can be further improved, and the stirring efficiency can be enhanced.

[0056] In addition, in the foregoing embodiments, the number of the connecting members 4 in the stirring mechanism 10 is also not limited, and can be one, two or more (that is, three or more). For example, see Figure 2, in some embodiments, the stirring mechanism 10 includes two connecting members 4, and these two connecting members 4 are arranged at intervals along the length direction of the stirring member 3. In this way, the stirring member 3 can be connected to the connecting sleeve 2 through the connecting member 4 at different positions in the length direction. Therefore, compared with the case where only one connecting member 4 is used to connect to the connecting sleeve 2, the connection reliability is stronger, which is more conducive to reducing the risk of detachment and improving the stirring efficiency.

[0057] Continue to refer to Figure 2 , as a further improvement to the foregoing embodiments, the stirring mechanism 10 not only includes the motor 1, the stirring member 3, the connecting sleeve 2 and the connecting member 4, but also includes a positioning portion 5. The positioning portion 5 is connected to the connecting sleeve 2 and is used to position the stirring member 3 so that the through hole 31 and the connecting hole 22 for the connecting member 4 to pass through are aligned with each other. In this way, under the action of the positioning portion 5, after the stirring member 3 is inserted into the connecting sleeve 2, it can be quickly positioned to achieve the alignment of the corresponding through hole 31 and the connecting hole 22. In this way, the assembly difficulty can be further reduced and the assembly efficiency can be improved.

[0058] Among them, the implementation manner of the positioning portion 5 can be various.

[0059] For example, the relative positional relationship between the positioning portion 5 and the stirring member 3 can be various. Exemplarily, the positioning portion 5 can be located on the side, above (the side close to the motor 1) or below (the side far from the motor 1) of the stirring member 3. As an example, refer to Figure 2 , in some embodiments, the positioning portion 5 is located on the side of the stirring member 3 close to the motor 1 and positions the stirring member 3 by contacting the end face of the stirring member 3. In this way, the positioning portion 5 does not affect the connection between the connecting sleeve 2 and the motor 1, and at the same time, it does not affect the stirring member 3 from being inserted into the connecting sleeve 2 from the end of the connecting sleeve 2 far from the motor 1 in the usual way. Moreover, the positioning portion 5 can conveniently contact the end face of the stirring member 3 during the process of the stirring member 3 being inserted into the connecting sleeve 2 from the end of the connecting sleeve 2 far from the motor 1 in the usual way to position the stirring member 3. When the stirring member 3 is inserted into the connecting sleeve 2 from the end of the connecting sleeve 2 far from the motor 1 and hits the positioning portion 5, it indicates that the stirring member 3 has been inserted in place, and the through hole 31 on the stirring member 3 has been aligned with the connecting hole 22 on the connecting sleeve 2, which is simple and convenient.

[0060] For another example, the structural form of the positioning portion 5 can be various. Exemplarily, the positioning portion 5 can be in various shapes such as square or annular. As an example, refer to Figure 2, in some embodiments, the positioning portion 5 includes a positioning ring 51. At this time, the positioning ring 51 is annular, facilitating full contact with the stirring member 3, especially the cylindrical stirring member 3, and enabling a better positioning effect. Among them, in some embodiments, the positioning ring 51 is a complete ring. In this case, the positioning ring 51 surrounds the connecting sleeve 2 in a full circle along the circumferential direction. In other embodiments, the positioning ring 51 includes at least two ring segments, and these at least two ring segments are arranged at intervals along the circumferential direction of the connecting sleeve 2. In this case, the positioning ring 51 is no longer a complete ring but includes several ring segments.

[0061] Based on the stirring mechanism 10 of the foregoing embodiments, the present application further provides a sewage treatment device 100, which includes a water tank 20 for containing sewage, and further includes the stirring mechanism 10 of any one of the embodiments. The stirring member 3 of the stirring mechanism 10 extends into the water tank 20 to stir the sewage added with a decontamination agent.

[0062] In addition, the present application further provides a cigarette production system, which includes the sewage treatment device 100 of the embodiments of the present application.

[0063] Next, in combination with Figure 2 the embodiments shown, the present application will be further described.

[0064] As Figure 2 shown, in this embodiment, the sewage treatment device 100 includes a water tank 20 and a stirring mechanism 10.

[0065] The water tank 20 is used for containing sewage and for adding decontamination agents such as polyaluminum chloride PAC and polyacrylamide PAM.

[0066] The stirring mechanism 10 is used for stirring the sewage added with a decontamination agent, and includes a motor 1, a connecting sleeve 2, a stirring member 3, two connecting members 4, and a positioning ring 51.

[0067] The output shaft 11 of the motor 1 is connected to the stirring member 3 through the connecting sleeve 2, so that the stirring member 3 is driven by the motor 1 to rotate to achieve the stirring function.

[0068] Among them, the output shaft 11 of the motor 1 and the connecting sleeve 2 can be connected in various ways in related technologies, which will not be elaborated here. Correspondingly, Figure 2 is not shown in detail, and similarly, Figure 1 is not shown in detail either. That is to say, Figure 1 and Figure 2 do not show the connection relationship between the motor 1 and the connecting sleeve 2 in detail, Figure 1 and Figure 2 the relationship between the motor 1 and the connecting sleeve 2 shown in does not constitute the only limitation of the relationship between the motor 1 and the connecting sleeve 2.

[0069] The connecting sleeve 2 is cylindrical, and its interior is provided with a chamber 21. Both ends of the chamber 21 are open, and two sets of connecting holes 22 are provided on the side wall of the chamber 21. These two sets of connecting holes 22 are arranged at intervals along the axial direction of the connecting sleeve 2, and each set of connecting holes 22 includes two connecting holes 22 located on the opposite side walls of the chamber 21. The two connecting holes 22 in the same set of connecting holes 22 are at the same axial position of the connecting sleeve 2 and face each other.

[0070] The stirring member 3 is cylindrical. It is inserted into the connecting sleeve 2, and two through holes 31 are provided thereon. These two through holes 31 are arranged at intervals along the axial direction of the stirring member 3 (i.e., the length direction of the stirring member 3) and correspond one-to-one with the two sets of connecting holes 22 on the connecting sleeve 2. Among them, each through hole 31 penetrates the opposite side walls of the stirring member 3.

[0071] Two connecting members 4 correspond one-to-one with the two sets of connecting holes 22 on the connecting sleeve 2, and each connecting member 4 includes a bolt 41 and two nuts 42. The bolt 41 is inserted into the connecting sleeve 2 from one connecting hole 22, passes through the corresponding through hole 31 on the stirring member 3, and then extends to the outside of the connecting sleeve 2 through the corresponding other connecting hole 22 and is locked by two nuts 42. In this way, the connection and fixation of the stirring member 3 and the connecting sleeve 2 can be realized.

[0072] The positioning ring 51 serves as the positioning portion 5. It is arranged on the inner wall of the connecting sleeve 2 and is located on the side of the stirring member 3 close to the motor 1. It is a complete ring that surrounds the connecting sleeve 2 for one full circle, so that it can position the stirring member 3 by contacting the end face of the stirring member 3 close to the motor 1, and realize the alignment of the two through holes 31 on the stirring member 3 and the two sets of connecting holes 22 on the connecting sleeve 2 respectively.

[0073] During assembly, the stirring member 3 is inserted into the connecting sleeve 2 until it abuts against the positioning ring 51. At this time, the two through holes 31 of the stirring member 3 are respectively aligned with the two sets of connecting holes 22 on the connecting sleeve 2. Then, two bolts 41 are respectively inserted, and two nuts 42 are respectively screwed on the two bolts 41, and the connection and fixation of the stirring member 3 and the connecting sleeve 2 can be realized.

[0074] Among them, since the stirring member 3 is connected to the connecting sleeve 2 by two bolts 41 at different axial positions, and each bolt 41 no longer abuts against the side of the stirring member 3 but passes through the stirring member 3. At the same time, each bolt 41 is fixed and locked by double nuts, so the stable connection of the stirring member 3 and the connecting sleeve 2 can be realized, effectively preventing the stirring member 3 from falling off, improving the structural reliability of the stirring mechanism 10, and improving the stirring efficiency.

[0075] Moreover, since both bolts 41 pass through the opposite side walls of the connecting sleeve 2 and extend to the outside of the connecting sleeve 2, it is convenient to select and screw the nuts 42. Therefore, the disassembly and assembly difficulty is small, the maintenance is convenient, and it saves time and effort.

[0076] It can be seen that the stirring mechanism 10 of this embodiment not only has high structural reliability, can achieve high stirring efficiency, but also is convenient for disassembly, installation and maintenance.

[0077] The above are only exemplary embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
