Abstract

A reaction kettle cleaning apparatus, includes a kettle body and a stirrer, the stirrer being located in the kettle body and including a stirring rod and a stirring portion, where a movable frame is disposed on the stirring rod and is movable along the stirring rod; and a cleaning device is disposed on the movable frame is configured to clean the kettle body; and the reaction kettle cleaning apparatus further includes a movable control apparatus configured to control the movable frame to move.

First claim

The invention claimed is:

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.

2. The reaction kettle cleaning apparatus according to claim 1 , wherein a sleeve ( 700 ) is disposed on the stirring rod ( 210 ) and is rotatable relative to the stirring rod ( 210 ).

3. The reaction kettle cleaning apparatus according to claim 2 , wherein a seal ring ( 701 ) is disposed between the sleeve ( 700 ) and the stirring rod ( 210 ).

4. The reaction kettle cleaning apparatus according to claim 1 , wherein a telescopic apparatus ( 500 ) is disposed between the movable frame ( 300 ) and the cleaning device ( 400 ).

5. The reaction kettle cleaning apparatus according to claim 4 , wherein the telescopic apparatus ( 500 ) is a scissors-type telescopic structure ( 510 ).
