Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 to 8 , the present utility model provides a reaction kettle for processing p-hydroxybenzoic acid, including a kettle body 1. The kettle body 1 is connected with a stirring mechanism for stirring materials. The stirring mechanism includes a motor 5, a rotating shaft 4, a plurality of connecting plates 13, a plurality of side scrapers 17, a plurality of bottom scrapers 15, a plurality of pressing rods 19, and a plurality of moving sleeves 12. The motor 5 is used to drive the rotating shaft 4 to rotate. The moving sleeve 12 is movably connected to the rotating shaft 4. One end of the pressing rod 19 is fixed to the moving sleeve 12, and the other end is slidably connected to the connecting plate 13. Both ends of the connecting plate 13 are pivotally connected to the side scraper 17 and the rotating shaft 4. The bottom scraper 15 is connected to the bottom of the rotating shaft 4. A driving mechanism for driving the moving sleeve 12 and the bottom scraper 15 to lift synchronously is connected inside the rotating shaft 4.

[0026] There may be three side scraping plates 17 and three bottom scraping plates 15. The included angle between adjacent side scraping plates 17 is 120°, and the included angle between adjacent bottom scraping plates 15 is 120°. Each single side scraping plate 17 corresponds to three connecting plates 13. There are three moving sleeves 12 distributed on the rotating shaft 4, and each single moving sleeve 12 corresponds to three connecting plates 13.

[0027] The top and bottom ends of the kettle body 1 are provided with a feed inlet 2 and a discharge outlet 16. The discharge outlet 16 is connected with an electromagnetic valve. During the material processing, the electromagnetic valve is closed. When the processing is completed, the electromagnetic valve is opened, and the material is discharged from the discharge outlet 16.

[0028] The motor 5 can drive the rotating shaft 4 to rotate, synchronously driving the rotation of the connecting plate 13, the pressing rod 19, the side scraping plate 17, and the bottom scraping plate 15, facilitating the stirring of the material. At this time, the side scraping plate 17 does not contact the inner side wall of the kettle body 1, and the bottom scraping plate 15 does not contact the inner bottom end of the kettle body 1, thereby reducing the contact friction. Moreover, the rotation of the bottom scraping plate 15 facilitates the stirring of the material at the inner bottom end of the kettle body 1, making the material stirring more sufficient.

[0029] The stirring mechanism further includes a plurality of slide rails 18 and a plurality of sliding blocks 20. The slide rails 18 are connected to the connecting plate 13, and the sliding blocks 20 are movably connected to the slide rails 18. The end of the pressing rod 19 is connected to the sliding block 20. When the lifting column 11 moves downward, it can drive the connecting block 21 to move downward, synchronously driving the three moving sleeves 12 to move downward. The pressing rod 19 moves downward and presses on the sliding block 20, causing the sliding block 20 to slide on the slide rail 18. Then, in cooperation with the use of the connecting plate 13, the side scraping plate 17 moves towards the direction close to the inner side wall of the kettle body 1. At the same time, the downward movement of the lifting column 11 drives the three bottom scraping plates 15 to move downward. When the side scraping plate 17 presses against the inner wall of the kettle body 1, the lifting column 11 stops moving, and the bottom scraping plate 15 presses against the inner bottom end of the kettle body 1, facilitating the scraping of the material.

[0030] The end of the pressing rod 19 is pivotally connected to the sliding block 20, and the sliding block 20 is slidably connected to the slide rail 18.

[0031] The driving mechanism includes a lifting column 11, a connecting disk 14, a plurality of connecting blocks 21, a T-shaped column 6, a moving plate 7, a locking head 8, and a guiding seat 10. The lifting column 11 is arranged inside the rotating shaft 4, and the bottom of the lifting column 11 is connected to the connecting disk 14. The end of the bottom scraping plate 15 is connected to the connecting disk 14. Both ends of the connecting block 21 are connected to the lifting column 11 and the moving sleeve 12. The end of the guiding seat 10 is connected to the rotating shaft 4, and the guiding seat 10 is used to guide the T-shaped column 6. The T-shaped column 6 is used to drive the lifting of the moving plate 7. The end of the moving plate 7 is connected to the lifting column 11. The locking head 8 is used to position the T-shaped column 6. The rotatable T-shaped column 6 drives the lifting of the moving plate 7, and the moving plate 7 can drive the lifting of the lifting column 11. After the lifting column 11 is in a suitable position, rotate the locking head 8 so that its end presses against the T-shaped column 6 to lock the T-shaped column 6, thereby improving the stability of the lifting column 11 and achieving a good positioning purpose.

[0032] The locking head 8 is a common bolt and is threadedly connected to the moving plate 7. Rotating the locking head 8 can position or loosen the T-shaped column 6.

[0033] The T-shaped column 6 is threadedly connected to the moving plate 7, and the end of the T-shaped column 6 is rotatably connected to the guiding seat 10 to improve the stability of the rotation of the T-shaped column 6.

[0034] A rectangular hole 9 is provided on the side of the rotating shaft 4, and the moving plate 7 is slidably connected to the rectangular hole 9, making the lifting of the moving plate 7 stable and improving the stability of the lifting of the lifting column 11.

[0035] The rotating shaft 4 is provided with a plurality of guiding holes 22, and the connecting blocks 21 are slidably connected to the corresponding guiding holes 22. The guiding holes 22 play a good guiding role for the connecting blocks 21, further ensuring the stability of the movement of the lifting column 11, and the rotation of the rotating shaft 4 can synchronously drive the rotation of the lifting column 11. The moving sleeve 12 is hermetically and slidably connected to the rotating shaft 4 and covers the guiding holes 22. During the lifting process of the lifting column 11, the moving sleeve 12 always seals the guiding holes 22, which can prevent materials from entering the rotating shaft 4 through the guiding holes 22.

[0036] A spring seat 23 is slidably connected within the rotating shaft 4. The lifting column 11 is fixedly connected to the spring seat 23 and is sheathed with a spring 24. One end of the spring 24 is connected to the spring seat 23, and the other end is connected to a plug 25. The lifting column 11 extends through the plug 25, which mates with a sealing surface 26 located at the bottom end of the rotating shaft 4. During the raising and lowering of the lifting column 11, the spring 24 remains compressed, exerting downward pressure on the plug 25, pressing it against the sealing surface 26 and preventing material from entering through the bottom of the rotating shaft 4, effectively blocking the entry of material. When the lifting column 11 descends, it simultaneously moves the spring seat 23 downward, further compressing the spring 24 and increasing the pressure exerted by the plug 25 on the sealing surface 26, thus improving the sealing performance of the connection between the two. When the lifting column 11 ascends (stirring the material), the spring seat 23 also ascends, but the spring 24 remains compressed, slightly reducing the downward pressure on the plug 25, effectively preventing material from entering the rotating shaft 4.

[0037] A U-shaped seat 3 is connected to the top of the kettle body 1 , a motor 5 is fixed to the top of the U-shaped seat 3 , and an output shaft of the motor 5 is connected to the rotating shaft 4 .

[0038] Working Principle: Material enters the kettle body 1 through the feed port 2, and the motor 5 drives the rotating shaft 4 to rotate, synchronously driving the connecting plate 13, the pressing rod 19, the side scrapers 17, and the bottom scraper 15 to rotate, achieving sufficient mixing and processing of the material. When the material is processed, the rotating T-shaped column 6 drives the movable plate 7 downward, synchronously driving the lifting column 11 downward, and the lifting column 11 drives the connecting block 21 downward, achieving the synchronous downward movement of the three movable sleeves 12, causing the pressing rod 19 to also move downward, and the sliding block 20 to slide on the slide rail 18. In conjunction with the use of the connecting plate 13, the side scraper 17 moves toward the inner side wall of the kettle body 1. At the same time, the downward movement of the lifting column 11 drives the connecting plate 14 to move downward, and the connecting plate 14 drives the three bottom scrapers 15 to move downward. The locking head 8 is used to lock the T-shaped column 6 to improve the stability of the lifting column 11. At this time, the side scrapers 17 are pressed against the inner side wall of the kettle body 1, and the bottom scrapers 15 are pressed against the bottom end of the kettle body 1. The motor 5 drives the rotating shaft 4 to rotate, realizing comprehensive scraping processing inside the kettle body 1, and the material is discharged from the discharge port 16, so that the material is fully utilized.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
