Benzene sulfonyl chloride is a commonly used sulfonating agent, and is used as a chemical raw material to prepare sulfonamides, sulfonated esters and sulfones. The production of benzene sulfonyl chloride is mainly through a series of reactions of chlorosulfonic acid and pure benzene to obtain crude benzene sulfonyl chloride, and then the crude benzene sulfonyl chloride is distilled to obtain the finished product. In the existing patent with the patent number CN208814923U, a device for preparing benzene sulfonyl chloride and diphenyl sulfone is disclosed.

[0039] Working principle: when in use, the support rod 302 and the reinforcing rod 303 on the fixing ring 301 are used to facilitate the fixing and arrangement of the whole device, according to the actual situation, before processing phenylsulfonyl chloride, the plurality of heating rods 603 on the protective cover 601 are connected with the power supply, then the heating rods 603 generate heat after being electrified, then the heat is diffused to all parts of the protective cover 601 through the plurality of heat pipes 602, and finally the heat is transmitted to all parts of the inner wall of the shell 1, so that the corresponding preheating work is facilitated, so as to promote the reaction efficiency of the device.

[0040] In actual processing, the motor 401 is connected with the power supply, then the motor 401 rotates to drive the rotating rod 402 to rotate, with the rotation of the rotating rod 402, the connecting block 403 thereon is also driven to rotate, and then the stirring paddle 404 is driven to rotate, so that the stirring of the material in the shell 1 is facilitated.

[0041] After processing, according to the actual situation, the through pipe 502 can be connected to the corresponding flushing liquid pipeline, and then the corresponding flushing liquid enters the through groove 503 in the rotating rod 402 through the through pipe 502 and the rotary joint 501, and then enters the inside of the plurality of connecting pipes 504, and is immediately sprayed out through the nozzles 505 on the connecting pipes 504 to spray and flush the inner wall of the shell 1, which facilitates the cleaning of impurities adhering to the inner wall of the shell 1, and further, the flushing liquid also synchronously enters the inside of the mounting block 506 to push the connecting rod 507, so that the connecting rod 507 is displaced under stress, and then drives the scraper block 508 to move together, and the first spring 509 is compressed at the same time, until the scraper block 508 abuts against the inner wall of the shell 1, and then the motor 401 drives the stirring paddle 404 to rotate together, which in turn drives the scraper block 508 to rotate together, thereby cleaning and scraping the inner wall of the shell 1, and further, by controlling the water pressure of the flushing liquid connected to the through pipe 502, the pressure on the connecting rod 507 can be easily controlled, and the extension length of the scraper block 508 can be easily adjusted to adapt to the different thicknesses of impurities accumulated on the inner wall of the shell 1, thereby ensuring the purity and efficiency of the subsequent reaction, and reducing the degree of corrosion of the device.

[0042] In addition, during actual preparation, the rotating rod 402 also drives the abutting rod 709 to rotate, and the abutting rod 709 rotates intermittently to abut and press the stressed rod 704 in the mounting block 703, and in this process, when the abutting rod 709 presses the stressed rod 704, the stressed rod 704 is displaced, thereby driving the push block 705 to move together, and the second spring 706 is compressed at the same time, until the push block 705 presses and pushes the pure benzene in the inner cavity, and the pure benzene is sprayed out of the one-way valve 707, which facilitates the addition of pure benzene into the shell 1, and when the abutting rod 709 no longer presses the stressed rod 704, the push block 705 returns to the original position under the action of the second spring 706, and then the pure benzene stored in the storage tank 701 enters the inner cavity of the push block 705 through the guide groove 708 to wait for the next pressure discharge process, so that pure benzene can be added synchronously under the driving of the rotating rod 402, ensuring the operation precision and the uniformity of the mixture, and without the need to increase the cost of the device, and the cover 702 can also be used to replenish the pure benzene in the storage tank 701 at any time.

[0043] On the other hand, the rotation of the rotating rod 402 also drives the first gear 802 in the mounting frame 801 to rotate, which in turn drives the two second gears 803 to rotate, thereby driving the two cross rods 804 to rotate, and finally driving the plurality of impellers 805 on the cross rods 804 to rotate together, thereby facilitating the turnover operation of the bottom of the inner cavity of the shell 1, avoiding deposition at the bottom of the reaction kettle, further ensuring the uniformity of the mixture, and reducing the plugging during discharge.
