[0039] An observation window is provided on the outside of the tank 1, which facilitates the observation of the preparation of the medicine.

[0040] The usage process of the oil and gas well cementing chemical mixing tank provided by this utility model is as follows: When it is necessary to prepare the chemical solution, in order to make the chemical solution more fully mixed, the fixed motor 6 is started. The output end of the fixed motor 6 drives the rotating main shaft 7 to rotate, thereby causing the stirring rod 8, which is fixedly connected to the rotating main shaft 7, to also rotate, thereby causing the stirring rod 8 to stir the liquid inside the tank 1.

[0041] When it is necessary to clean the outer side of the rotating main shaft 7 and the stirring rod 8 and the inner wall of the tank 1, press the sliding plate 22 to the bottom so that the sliding plate 22 is no longer engaged with the rotating plate 18 through the locking groove 19. Then rotate the rotating plate 18, so that the screw 17 fixedly connected to the rotating plate 18 also rotates. Since the screw 17 is threadedly connected to the threaded sleeve 16, the movement of the screw 17 drives the second locking plate 15 fixedly connected to the threaded sleeve 16 to move, so that the second locking plate 15 is no longer engaged with the first locking plate 12. At this time, the top cover 4 can be removed to clean the outer side of the rotating main shaft 7 and the stirring rod 8 and the inner wall of the tank 1.

[0042] The snap-fit ​​structure allows the top cover 4 to be completely detached from the tank 1, exposing all the internal surfaces of the tank 1, avoiding residual medicine or cleaning agent in traditional threaded or flanged connections, and reducing the risk of cross-contamination.

[0043] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to specific implementations. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
