[0020] Further, the top end of the reactor 1 is also provided with a feed inlet 20, and the bottom end of the reactor 1 is provided with a discharge pipe 19, and a plurality of supporting legs 18 are installed to support and fix the reactor 1.

[0021] Based on the above, after the reactor 1 completes the work, the inner wall of the reactor 1 is cleaned by the high-pressure cleaning device. In this process, the adjusting member drives the anti-sticking member to flip and move, so that the anti-sticking member contacts the inner wall of the reactor 1. The driving member 2 and the stirring shaft 3 drive the anti-sticking member to rotate so that it is scraped along the inner wall of the reactor 1. The high-pressure cleaning device cleans the inner wall of the reactor 1. After cleaning is completed, the protective member is used for heating to eliminate the water stains remaining on the inner wall of the reactor 1.

[0022] A supporting frame 5 is installed at the bottom of the inner cavity of the reactor 1, and a fixing disc 6 is installed at the top end of the supporting frame 5. A bearing 7 is embedded in the middle of the fixing disc 6, and the bottom end of the stirring shaft 3 is inserted into the inside of the bearing 7.

[0023] Based on the above, the stirring shaft 3 is inserted into the fixing disc 6 on the supporting frame 5 during rotation, which provides fixing and limiting effect for the stirring shaft 3.

[0024] The protective member includes a vacuum cover 8 sleeved on the outer wall of the reactor 1, and a vacuum chamber 9 is formed between the inner wall of the vacuum cover 8 and the outer wall of the reactor 1. A plurality of heating rods 10 are installed in the vacuum chamber 9.

[0025] Based on the above, by setting the vacuum cover 8, the vacuum chamber 9 is formed outside the reaction kettle 1, and in the process of cleaning the residues by sticking the anti-sticking part to the inner wall of the reaction kettle 1, the noise generated by the friction and collision between the anti-sticking part and the inner wall of the reaction kettle 1 can be isolated to a certain extent, and the heating rod 10 can dry and evaporate the water stains remaining on the inner wall of the reaction kettle 1 after the high-pressure flushing is completed.

[0026] The anti-sticking part comprises a long strip-shaped scraper 11, and a plurality of hinged shafts 12 are connected between the scraper 11 and the stirring blade 4. The scraper 11 is flipped and rotated with the stirring blade 4 through the hinged shaft 12;

[0027] When the scraper 11 and the stirring blade 4 are flipped to the same plane, the edge of the scraper 11 away from the stirring blade 4 is attached to the inner wall of the reaction kettle 1, and an inclined arc surface 13 is arranged at the edge of the scraper 11 away from the stirring blade 4.

[0028] Based on the above, in the normal stirring reaction process of the reaction kettle 1, the scraper 11 is flipped and separated from the inner wall of the reaction kettle 1 through the hinged shaft 12, and in the cleaning process of the inner wall of the reaction kettle 1 after the reaction is completed, the scraper 11 is flipped and contacted with the inner wall of the reaction kettle 1 through the hinged shaft 12 for scraping and cleaning. The inclined arc surface 13 facilitates the contact or separation of the scraper 11 with the inner wall of the reaction kettle 1 during flipping.

[0029] The adjusting part comprises two micro push rods 14 and a sleeve box 15 located between the scraper 11 and the stirring blade 4. The two micro push rods 14 are respectively fixed at the top end and the bottom end of the stirring blade 4, and the output shaft of the micro push rod 14 faces the side of the scraper 11. The top end and the bottom end of the sleeve box 15 are flush with the top end and the bottom end of the stirring blade 4, respectively.

[0030] The sleeve box 15 is internally provided with a slot 16, and a connecting rod 17 is inserted into the slot 16. The outer wall of the connecting rod 17 is attached to the inner wall of the slot 16. The top end and the bottom end of the connecting rod 17 are respectively connected with the output shaft end of the two micro push rods 14.

[0031] Based on the above, in the normal stirring reaction process of the reaction kettle 1, the scraper 11 is separated from the inner wall of the reaction kettle 1, as shown in Figure 2 、 Figure 4 and Figure 5 , the micro push rod 14 works to drive the connecting rod 17 to move away from the stirring blade 4, so that the connecting rod 17 pushes the sleeve box 15 to move outward in the slot 16. The movement of the sleeve box 15 drives the scraper 11 to flip at the edge of the stirring blade 4 through the hinged shaft 12, so that the scraper 11 rotates and separates from the stirring blade 4. The edge of the scraper 11 is separated from the inner wall of the reaction kettle 1, and at this time the stirring blade 4 can normally perform stirring reaction;

[0032] After the reaction in the reaction kettle 1 is completed, the inner wall of the reaction kettle 1 needs to be cleaned of residual material, so the edge of the scraper 11 is brought into contact with the inner wall of the reaction kettle 1, as shown in Figure 3 The micro push rod 14 is operated to move the connecting rod 17 to one side of the stirring blade 4, pull the sleeve box 15 and the scraper 11 to flip to one side of the stirring blade 4 and close to the stirring blade 4, so that the scraper 11 and the stirring blade 4 are moved to the same plane, at this time the edge of the scraper 11 is attached to the inner wall of the stirring shaft 3, then the driving part 2 is operated to drive the stirring shaft 3 and the stirring blade 4 to rotate in the inner cavity of the reaction kettle 1, the scraper 11 is scraped along the inner wall of the reaction kettle 1, and the residual material is removed from the inner wall of the reaction kettle 1 by cooperating with the high-pressure cleaning device, then the heating rod 10 is operated to heat and dry the water stains remaining on the inner wall of the reaction kettle 1, so that the inner wall of the reaction kettle 1 is prevented from sticking and cleaned.

[0033] Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art and related fields without creative labor should belong to the scope of protection of the present application.
