1. A reaction kettle cleaning apparatus, comprising a kettle body (100) and a stirrer (200), the stirrer (200) being located in the kettle body (100) and comprising a stirring rod (210) and a stirring portion (220), wherein:
the kettle body (100) comprises a concealed seal cavity (110) and a stirring cavity (120), seal cavity covers (800) are disposed between the concealed seal cavity (110) and the stirring cavity (120), the stirring portion (220) operates inside the stirring cavity (120);
a movable frame (300) is disposed on the stirring rod (210) and is movable along the stirring rod (210);
a cleaning device (400) is disposed on the movable frame (300) and is configured to clean the kettle body (100); and
the reaction kettle cleaning apparatus further comprises a movable control apparatus (600) configured to control the movable frame (300) to move, and the movable control apparatus (600) comprises a rope winder (610) and a sling (620);
the movable frame (300) is provided with a noncircular hole (310), and the stirring rod (210) comprises a noncircular cross-sectional segment (211);
the stirring rod (210) comprises a circular cross-sectional segment (212);
the circular cross-sectional segment (212) is located on an upper side of the stirring rod (210), and the noncircular cross-sectional segment (211) is located on the lower side of the stirring rod (210);
the noncircular hole (310) of the movable frame (300) corresponds in shape and size to the noncircular cross-sectional segment (211) of the stirring rod (210), and the movable frame (300) is sleeved over the stirring rod (210) through the noncircular hole (310);
when the movable frame (300) moves to a position of the circular cross-sectional segment (212) of the stirring rod (210), the movable frame (300) does not affect the rotation of the stirring rod (210), that is, when the stirring rod (210) rotates, the cleaning device (400) does not rotate along, making it convenient for the cleaning device (400) to move to the concealed seal cavity (110) and enter a concealed state when the cleaning device (400) does not need to operate; and
when the movable frame (300) moves to a position of the noncircular cross-sectional segment (211) of the stirring rod (210), the stirring rod (210) rotates to drive the movable frame (300) to rotate, and then drive the cleaning device (400) to rotate, making it more convenient for the cleaning device (400) to perform cleaning operation.
