The crystallizer is a key equipment in the sugar production process, and it plays an important role in the quality of sugar. The stirring of the crystallizer is a key component in the development of the sugar-making and boiling process from natural circulation to forced circulation. During the sugar-making and boiling process, the syrup in the crystallizer accelerates the circulation under the stirring action, and the water in the syrup evaporates quickly, shortening the boiling time and improving production efficiency. The traditional crystallizer stirring fixing method is that the blade shaft sleeve and the stirring shaft are fixed by welding. Therefore, the inventor found the following problems in the process of use:
[0003] The biggest problem with this method is the existence of welding stress and welding deformation. After the stirring shaft and the blade sleeve are welded, a special process is required to eliminate stress and deformation. In addition, during the welding process, the sparks generated may pose a personal safety hazard to the workers. After welding, if a certain position of the mechanism is damaged, the entire welded structure may need to be replaced, which undoubtedly increases the work cost and has certain disadvantages.

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.
[0025] like Figure 1 As shown, a lower support fixing assembly of a stirring shaft includes a stirring shaft 10 and a plurality of blades 12. A fixing device for limiting and fixing the plurality of blades 12 is arranged on the side wall of the stirring shaft 10, and the fixing device includes a connecting plate 11. A protective device is also arranged on the side wall of the stirring shaft 10, and the protective device includes a blade sleeve 14.
[0026] During specific use, the fixing device can fix the blade 12, which can not only increase the use effect of the blade 12, but also make it easier to replace the blade 12. The protective device can protect the stirring shaft 10 to prevent damage to the stirring shaft 10 and increase working costs.
[0027] To sum up, by setting up a fixing device and a protective device, the fixing device can be used to limit and fix the blade 12, which can not only make the blade 12 stir more powerfully, but also make it more convenient for the staff to replace the blade 12. The protective device can effectively protect the stirring shaft 10 and can effectively increase the service life of the stirring shaft 10.
[0028] like Figure 2 As shown, a threaded column 13 is fixedly installed on the bottom wall of the stirring shaft 10, a round nut 15 is fixedly installed on the bottom wall of the blade sleeve 14, the blade sleeve 14 is sleeved on the side wall of the stirring shaft 10, and the round nut 15 is threadedly connected to the threaded column 13.
[0029] During specific use, through the sleeve connection between the blade sleeve 14 and the side wall of the stirring shaft 10 and the threaded connection between the round nut 15 and the threaded column 13, the blade sleeve 14 can protect the side wall of the stirring shaft 10 during operation. Through the convenient installation and disassembly characteristics of the round nut 15 and the threaded column 13, the blade sleeve 14 can be easily replaced after being damaged, and it is also convenient to replace the blade 12.
[0030] In summary, by setting the stirring shaft 10, the threaded column 13, the blade sleeve 14 and the round nut 15, the stirring shaft 10 can be protected by the blade sleeve 14. When the blade sleeve 14 is damaged, the blade sleeve 14 can be conveniently replaced by conveniently connecting the round nut 15 and the threaded column 13. It is easy to use and has a simple structure.
[0031] like Figure 2 , Figure 3 and Figure 4 As shown, a connecting plate 11 is fixedly mounted on the side wall of the blade sleeve 14, a plurality of limit plates 17 are arranged in an annular array on the side wall of the connecting plate 11, and two groups of first threaded holes 16 are opened in an arc-shaped array on the side wall of the connecting plate 11.
[0032] Two first bolts 18 are provided at one end of the limiting plate 17 away from the connecting plate 11. Both first bolts 18 penetrate the limiting plate 17 and are threadedly connected to the limiting plate 17. The first bolts 18 are also threadedly connected to the corresponding first threaded holes 16, so that the side wall of the limiting plate 17 close to the connecting plate 11 fits with the connecting plate 11.
[0033] The plurality of blades 12 are respectively arranged on one end of the limiting plate 17 away from the connecting plate 11 . The number of the blades 12 corresponds to the number of the limiting plates 17 . A second bolt 21 is fixedly installed on a wall surface of one side of the blade 12 close to the limiting plate 17 .
[0034] A second threaded hole 19 is formed on a side wall of the limiting plate 17 away from the connecting plate 11 , and a second bolt 21 is threadedly connected to the second threaded hole 19 . A second bolt 21 is formed on the side wall of the second bolt 21 . A third threaded hole 20 is formed on the side wall corresponding to each of the plurality of limiting plates 17 .
[0035] A third bolt 22 is disposed on one side wall of the limiting plate 17 where the third threaded hole 20 is formed. The third bolt 22 penetrates through the third threaded hole 20 and the second bolt 21 and is threadedly connected to the third threaded hole 20 .
[0036] During specific use, the blade 12 is threadedly connected to the wall surface of the limiting plate 17 through the second bolt 21 and the limiting plate 17, and the blade 12 is fixed by the third bolt 22 passing through the third threaded hole 20 and the second bolt 21. This not only allows the staff to easily replace the blade 12, but also prevents the blade 12 from rotating during the stirring process, so that the blade 12 can perform the stirring operation better. The limiting plate 17 is threadedly connected to the side wall of the connecting plate 11 through the first bolt 18 and the first threaded hole 16. In this way, the blade 12 is limited and fixed. The side wall of the connecting plate 11 is arc-shaped. If you want to achieve the effect that the third bolt 22 can achieve, a certain production cost is required. Connecting through the limiting plate 17 can effectively reduce the production cost to achieve the above effect.
[0037] To sum up, by providing the connecting plate 11, the paddle 12, the first threaded hole 16, the limiting plate 17, the first bolt 18, the second threaded hole 19, the third threaded hole 20, the second bolt 21 and the third bolt 22, the paddle 12 can be limited by the threaded connection between the second bolt 21 and the second threaded hole 19, so that the paddle 12 can be better stirred. The limiting plate 17 can be provided to save the manufacturing cost of the structure. Compared with the prior art, welding operations are not required, which not only makes it unnecessary to replace the entire structure if it is damaged, but also protects the personal safety of the welders and reduces the working costs.
