[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figure 1-5 The apparatus shown is for the preparation of 4-chlorophthalic anhydride, including a reaction vessel 1, and further comprising:

[0025] Cleaning brush 2 is installed inside reaction vessel 1;

[0026] The connecting component 4 is used to fix the position of the cleaning brush 2. The connecting component 4 includes a connecting block 401 fixedly connected to the back of the cleaning brush 2. A crossbar 404 is provided on one side of the connecting block 401. A positioning groove 403 is provided on one side of the crossbar 404. A positioning block 402 is fixedly connected to one side of the connecting block 401. A locking member 5 for fixing the position of the positioning block 402 is provided at the connection between the positioning block 402 and the crossbar 404.

[0027] Rotating component 3 is located on the back of crossbar 404 and is used to drive crossbar 404 to rotate.

[0028] It should be noted that the connecting block 401 is fixed to the back of the cleaning brush 2. The cleaning brush 2 is used to clean the inside of the reaction vessel 1. When it is necessary to fix the connecting block 401, the positioning block 402 on one side of the connecting block 401 is first inserted into the positioning groove 403 opened on the crossbar 404, and the positioning block 402 is fixed in the positioning groove 403 by the locking piece 5. The crossbar 404 is fixed on the rotating assembly 3, and the rotating assembly 3 drives the crossbar 404 and the cleaning brush 2 to move. This cleans the inner wall of the reaction vessel 1. During use, the locking element 5 is used to install and remove the positioning block 402 and the crossbar 404. When needed, the cleaning brush 2, connecting block 401, and positioning block 402 are moved into the interior of the reaction vessel 1 and fixed by the locking element 5. After use, the positioning block 402 is removed from the crossbar 404 by the locking element 5, and the cleaning brush 2, connecting block 401, and positioning block 402 are removed from the interior of the reaction vessel 1.

[0029] Specifically, the rotating assembly 3 includes a positioning sleeve 303 fixedly connected to one end of the crossbar 404, a rotating shaft 301 inserted through the middle of the positioning sleeve 303, a motor 302 fixedly connected to the top of the reaction vessel 1, and the rotating shaft 301 fixedly connected to the output end of the motor 302.

[0030] It should be noted that the reaction vessel 1 is an electrically heated reaction vessel of model TJ-001, the motor 302 is an existing servo motor, and the positioning sleeve 303 is fitted onto the middle of the rotating shaft 301 and fixed to the rotating shaft 301 by bolts. In use, the motor 302 drives the rotating shaft 301 to rotate, and the rotating shaft 301 drives the positioning sleeve 303 and the crossbar 404 to rotate.

[0031] Specifically, the locking component 5 includes a storage groove 503 formed on one side of the positioning block 402, a locking block 507 inserted inside the storage groove 503, a locking hole 509 formed on the inner wall of one side of the positioning groove 403, a connecting hole 505 formed on the inner wall of the top of the locking hole 509 communicating with the locking hole 509, the locking block 507 inserted inside the locking hole 509, and a bearing 501 fixedly connected to the inner wall of one side of the storage groove 503, with the bearing 501 having a central portion... A threaded rod 504 is inserted and connected to the middle of the locking block 507. A torsion cap 508 for rotating the threaded rod 504 is provided on one side of the crossbar 404. The torsion cap 508 is fixedly connected to one end of the threaded rod 504. A limiting block 502 is symmetrically fixedly connected to the inner wall of the top and bottom of the storage groove 503. A limiting groove 506 is symmetrically opened at the top and bottom of the locking block 507. The limiting block 502 is inserted and connected inside the limiting groove 506.

[0032] It should be noted that the positioning groove 403 is adapted to the positioning block 402, allowing the positioning block 402 to pass into the interior of the positioning groove 403. The connecting hole 505 is adapted to the threaded rod 504, allowing the threaded rod 504 to pass through the connecting hole 505 into the interior of the locking hole 509. The width of the connecting hole 505 is smaller than the diameter of the locking hole 509, so the locking block 507 cannot pass through when it is inserted into the locking hole 509. The bearing 501 is sleeved on the threaded rod 504. At the other end, it is used to fix the position of the threaded rod 504 during use; the limiting groove 506 is adapted to the limiting block 502. When the locking block 507 moves, the limiting block 502 slides inside the limiting groove 506 and restricts the rotation of the locking block 507. When it is necessary to move the position of the locking block 507, the torsion cap 508 is rotated, the torsion cap 508 drives the threaded rod 504 to rotate, and the threaded rod 504 drives the locking block 507, which is threaded to it and cannot rotate, to move.

[0033] Furthermore, when it is necessary to fix the position of the positioning block 402, the positioning block 402 is first inserted into the positioning groove 403, and the torsion cap 508 is located on one side of the crossbar 404. While moving the positioning block 402, the threaded rod 504 is inserted into the locking hole 509 through the connecting hole 505. Then, by rotating the torsion cap 508, the locking block 507 is moved into the locking hole 509, and the position of the positioning block 402 is fixed by the locking block 507.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
