[0041] In order to make the personnel in the technical field better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the scope of protection of the present application.

[0042] According to the embodiment of the utility model, provide a kind of detachable polymerization kettle stirrer, please refer to Figures 1 to 4 , including: stirring shaft 1;Fixed component 2, the fixed component 2 with the detachable connection of stirring shaft 1, the fixed component 2 includes: first flange plate 21, the detachable connection of first flange plate 21 with stirring shaft 1;Connecting portion 23, the detachable connection of connecting portion 23 with first flange plate 21;Stirring main body 3, the detachable connection of stirring main body 3 with connecting portion 23.

[0043] By adopting the above device, the connecting part 23 detachably connects the stirring shaft 1 and the stirring body 3, solves the problem that the stirrer is likely to be damaged during stirring, and the commonly used stirrer is currently integrated, which is inconvenient to maintain and replace.

[0044] Please refer to Figure 4 , the connecting part 23 comprises: a first connecting plate 231, which is detachably connected with the first flange plate 21; a second connecting plate 232, which is detachably connected with the first connecting plate 231, and the side of the second connecting plate 232 away from the stirring shaft 1 is detachably connected with the stirring body 3.

[0045] By adopting the above device, the first flange plate 21 and the stirring body 3 are connected through the first connecting plate 231 and the second connecting plate 232, and the first connecting plate 231 and the second connecting plate 232 are overlapped and then fixed, which can reduce the frictional resistance when the stirrer operates to a certain extent.

[0046] Please refer to Figure 1 and Figure 4 , the first connecting plate 231 and the second connecting plate 232 are symmetrically distributed with the axis of the stirring shaft 1.

[0047] By adopting the above device, the symmetrical distribution of the first connecting plate 231 and the second connecting plate 232 can complete the overall fixation of the stirring shaft 1 and the stirring body 3.

[0048] Please refer to Figure 4 , the first connecting plate 231 and the second connecting plate 232 are made of stainless steel, and / or the transverse cross section of the first connecting plate 231 and the second connecting plate 232 is elliptical.

[0049] By adopting the above device, the transverse cross section of the first connecting plate 231 and the second connecting plate 232 is elliptical, and compared with the traditional circular or square structure, the elliptical structure can reduce the contact area. Smaller contact area means that under the same pressure, the pressure on the unit area is larger, which helps to form a more stable oil film (if lubrication is used), thereby reducing the direct contact between solids and reducing friction. The elliptical structure can better adapt to forces in different directions, so that the load can be evenly distributed over a larger area. This improved load distribution reduces local stress concentration and avoids additional friction caused by excessive wear. The design of stacking up and down can increase the rigidity and stability of the system, reduce the vibration and impact that may occur during operation. A smooth operating environment is conducive to maintaining good cooperation between moving parts, thereby reducing friction.

[0050] Please refer toFigure 1 The polymeric kettle agitator further comprises a scraper 4 detachably connected with the agitator body 3.

[0052] Please refer to Figure 1 The scraper 4 is made of polytetrafluoroethylene.

[0053] By using the above device, the scraper 4 is made of polytetrafluoroethylene, which has the advantages of high temperature resistance, corrosion resistance, and high plasticity. Polytetrafluoroethylene has a very low friction coefficient and does not adhere to almost all substances, which makes it very suitable for use as a scraper material and can easily scrape off the material from the surface without leaving residues.

[0054] Please refer to Figure 1 The scraper 4 is in the shape of a long strip, and the end away from the agitator body 3 is in the shape of a smooth transition slope.

[0055] By using the above device, the scraper 4 has a slope at one end, which facilitates the scraping of the material.

[0056] Please refer to Figure 1 The agitator body 3 is provided with a plurality of mounting holes formed in a semi-closed structure with the opening facing away from the agitator body 3, which are composed of two parallel straight line segments and an arc-shaped portion connecting the two segments.

[0057] By using the above device, the mounting hole formed in a semi-closed structure with the opening facing away from the agitator body 3 is composed of two parallel straight line segments and an arc-shaped portion connecting the two segments, that is, an Ω-shaped mounting hole similar to the shape of the Greek letter "Ω". The Ω-shaped mounting hole facilitates the installation and removal of the scraper 4.

[0058] Please refer to Figure 1 and Figure 4 The second connecting plate 232 is connected and fixed with the first connecting plate 231 by two locking bolts 5, and the side away from the stirring shaft 1 is connected and fixed with the agitator body 3 by a single-head bolt 6.

[0059] By adopting the above device, the first connecting plate 231 and the second connecting plate 232 are connected through the cooperation of the two locking bolts 5 and the nuts, the stirring main body 3 is connected with the second connecting plate 232 through the single-end bolt, and the locking bolt 5 and the nut connection mode can better fix the stability of the first connecting plate 231, the second connecting plate 232 and the first flange plate 21, so that the first connecting plate 231 and the second connecting plate 232 better cooperate with each other when the stirring shaft 1 rotates.

[0060] Please refer to Figure 1 , the fixing assembly 2 further comprises:

[0061] The second flange plate 22 is detachably connected with the stirring shaft 1.

[0062] By adopting the above device, the stirring shaft 1 is fixed with the first flange plate 21 and the second flange plate 22 through the fixing of the pin, so as to enhance the stability of the first flange plate 21, the second flange plate 22 and the stirring shaft 1.

[0063] In the specific embodiment, the first flange plate 21 and the second flange plate 22 are fixed on the stirring shaft through the pin, one end of the first connecting plate 231 and the second connecting plate 232 is fixedly connected with the first flange plate 21 through the locking bolt 5, so as to better stabilize the first flange plate 21 and the second flange plate 22, the other end of the second connecting plate 232 is fixedly connected through the single-end bolt, and the first flange plate 21, the single-end bolt 6 and the first connecting plate 231 and the second connecting plate 232 are detachably connected, so that the stirring main body 3 is stably connected with the stirring shaft 1.
