Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] Example:

[0039] like Figure 1-9 As shown, this embodiment proposes a strong stirring nitration reaction kettle, including a tank body 10, and a support frame 20 is arranged on the tank body 10;

[0040] A stirring rod 40 is rotatably provided on the support frame 20, and the stirring rod 40 extends into the inner cavity of the tank body 10. A stirring blade 42 is provided on the outer wall of the stirring rod 40. A connecting sleeve 50 is rotatably provided on the inner wall of the bottom end of the tank body 10. A supporting sleeve 41 is provided on the outer wall of the stirring rod 40. A scraper 60 is provided between the supporting sleeve 41 and the connecting sleeve 50. The scraper 60 is in close contact with the inner wall of the tank body 10. The stirring rod 40 is provided on the connecting sleeve 50. A locking rod 70 is provided in the stirring rod 40. The locking rod 70 is in contact with the connecting sleeve 50, so that the connecting sleeve 50 and the stirring rod 40 are connected as a whole.

[0041] In this embodiment, when cleaning the residual impurities on the inner wall of the tank body 10, the locking rod 70 is moved so that the locking rod 70 contacts the connecting sleeve 50, so that the connecting sleeve 50 and the stirring rod 40 are connected as a whole. Then, during the rotation of the stirring rod 40, the connecting sleeve 50 rotates with the stirring rod 40, thereby driving the scraper 60 to rotate on the inner wall of the tank body 10 to remove the impurities on the inner wall of the tank body 10. When only the stirring blade 42 needs to rotate, the locking rod 70 is moved so that the locking rod 70 does not contact the connecting sleeve 50, so that when the stirring rod 40 rotates, the connecting sleeve 50 is not driven to rotate;

[0042] Of course, when the mixing efficiency needs to be improved, the connecting sleeve 50 can be made to rotate along with the stirring rod 40;

[0043] By rotatably setting the connecting sleeve 50 on the inner wall of the bottom end of the tank body 10, sleeve-setting the supporting sleeve 41 on the outer wall of the stirring rod 40, and arranging the scraper 60 between the two, the structure can drive the scraper 60 to be in close contact with the inner wall of the tank body 10 when the stirring rod 40 rotates, so as to effectively remove impurities on the inner wall of the tank body 10, thereby improving the stirring efficiency and convenience;

[0044] By setting the locking rod 70, the switchable connection state between the connecting sleeve 50 and the stirring rod 40 is realized. When the inner wall of the tank body 10 needs to be cleaned, the locking rod 70 pushes the connecting sleeve 50 and the stirring rod 40 to connect as a whole, and the scraper 60 rotates accordingly to clean the inner wall; when only stirring is needed but no cleaning is required, the locking rod 70 can be withdrawn, so that the stirring rod 40 rotates alone without driving the connecting sleeve 50 and the scraper 60. This structural design provides users with a multifunctional working mode, increasing the applicability and flexibility of the equipment;

[0045] At the same time, according to the requirement of improving the mixing efficiency, the locking rod 70 can be operated to control whether the connecting sleeve 50 rotates with the stirring rod 40, thereby realizing a simple adjustment of the mixing efficiency to meet the needs of different working conditions.

[0046] Specifically, a liquid outlet pipe 11 is provided on the inner wall of the bottom end of the tank body 10, and a fixing sleeve 12 is provided at the liquid outlet pipe 11, and the fixing sleeve 12 is coaxially arranged with the liquid outlet pipe 11;

[0048] In this embodiment, the liquid outlet pipe 11 can be easily discharged from the tank body 10. At the same time, due to the setting of the fixing sleeve 12 and the fixing rod 13, the liquid outlet efficiency of the liquid outlet pipe 11 is not affected while the connecting sleeve 50 is easy to rotate.

[0049] Specifically, the connecting sleeve 50 is provided with a connecting rod 52, and the stirring rod 40 is provided with a connecting hole 43;

[0050] The connecting rod 52 is rotatably disposed in the connecting hole 43 .

[0051] In this embodiment, the cooperation between the connecting rod 52 and the connecting hole 43 can facilitate the independent rotation of the stirring rod 40.

[0052] Specifically, a locking cavity A44 is provided in the stirring rod 40, and a locking cavity B51 is provided on the connecting rod 52;

[0053] The positions and sizes of the locking chamber A44 and the locking chamber B51 match each other. The locking rod 70 is slidably disposed in the locking chamber A44. The locking rod 70 extends into the locking chamber B51, so that the stirring rod 40 and the connecting sleeve 50 are connected as a whole.

[0054] In this embodiment, when the connecting sleeve 50 and the stirring rod 40 need to be connected as one, the locking rod 70 is moved in the locking cavity A44 until the locking rod 70 extends into the locking cavity B51, so that during the rotation of the stirring rod 40, the connecting sleeve 50 is driven to rotate through the locking rod 70.

[0055] Specifically, the axis of the locking cavity A44 is not coaxial with the axis of the stirring rod 40.

[0056] In this embodiment, the above-mentioned different shaft settings can facilitate the connection sleeve 50 to rotate along with the rotation of the stirring rod 40.

[0058] The locking rod 70 is provided with a toggle rod 71 , and the toggle rod 71 is slidably disposed in the moving groove 45 .

[0059] Specifically, a fixed groove 46 is formed on the movable groove 45, and the toggle rod 71 is moved into the fixed groove 46, so that the locking rod 70 is placed in the locking cavity A44.

[0060] In this embodiment, when the locking rod 70 needs to be placed in the locking cavity A44, the toggle rod 71 is manually driven to rotate about the axis of the locking rod 70, so that the toggle rod 71 disengages from the fixed groove 46, and then drives the toggle rod 71 to slide down in the movable groove 45, thereby inserting the locking rod 70 into the locking cavity A44.

[0061] Specifically, the support frame 20 is provided with a toggle notch 21, and the toggle notch 21 matches the position of the toggle rod 71;

[0062] The support frame 20 is provided with a stirring motor 30 , and the stirring motor 30 is drivingly connected to a stirring rod 40 .

[0063] In this embodiment, the toggle notch 21 can be used to drive the toggle rod 71 to rotate and move.
