[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0033] Refer to Figure 1 - Figure 3 , an embodiment provided by the present invention: A maleic anhydride circulating feeding device includes a fixed plate 5, a motor 1 6 is fixedly connected inside the fixed plate 5, a gear 7 is fixedly connected to the output end of the motor 1 6, a slide block 10 is rotatably connected inside the fixed plate 5, a turntable 9 is fixedly connected to the top of the slide block 10, a rack 8 is fixedly connected inside the turntable 9, the rack 8 meshes with the gear 7, a plurality of connecting bars 11 are fixedly connected to the top of the turntable 9, a connecting block 12 is rotatably connected to the outer wall of each connecting bar 11, a connecting bar 13 is fixedly connected to the top of each connecting block 12, a connecting block 16 is rotatably connected to the outer wall of the connecting bar 13, a connecting bar 15 is rotatably connected inside each connecting block 16, a fixed block 14 is fixedly connected to the bottom of the connecting bar 15, the bottom of the fixed block 14 is fixedly connected to the top of the turntable 9, and a stirring assembly is arranged on the top of the connecting block 16, and the stirring assembly is used for crushing maleic anhydride agglomerates.

[0034] Specifically, first, when the maleic anhydride particles enter the feeding hopper 4, the operator starts the first motor 6. The first motor 6 drives the gear 7 to start rotating through its output end. The gear 7 meshes with the rack 8 on the turntable 9, thereby driving the turntable 9 to start rotating. At this time, the design of the first slider 10 plays a role in supporting the turntable 9, ensuring its stable rotation without unnecessary vibration or deviation. When the turntable 9 rotates, through the first connecting bar 11, the first connecting block 12 also rotates accordingly. Through the second connecting bar 13, the second connecting block 16 is driven to perform a limited rotation movement with the third connecting bar 15 as the center, ensuring that when the maleic anhydride particles are discharged from the bottom outlet of the feeding hopper 4, they can flow out at an appropriate speed and particle size to match the requirements of other production processes, thereby avoiding affecting the entire production line, improving the production efficiency and the stability of product quality, and enhancing the practicality of the equipment and the convenience of operation.

[0035] Refer to Figure 1 、 Figure 4 and Figure 5 , the stirring assembly includes a stirring block 26. The outer wall of the stirring block 26 is provided with a feeding hopper 4. The bottom of the feeding hopper 4 is arranged at the top of the second connecting block 16. The bottom of the fixing plate 5 is fixedly connected to the inside of the supporting block 3. The bottom of the supporting block 3 is fixedly connected to a conveyor belt 1. The top of the conveyor belt 1 is provided with a holding basket 2. The top of the holding basket 2 is arranged at the bottom of the second connecting block 16. A plurality of second fixing blocks 17 are fixedly connected inside the feeding hopper 4. The inner walls of the second fixing blocks 17 are all fixedly connected with second motors 18. The output ends of the second motors 18 are all fixedly connected with first connecting columns 19. The outer walls of the first connecting columns 19 are all slidably connected to the inner walls of the second fixing blocks 17. One end of each first connecting column 19 is fixedly connected with a third connecting block 20. Both sides inside the third connecting block 20 are slidably connected with fourth connecting bars 21. One end of each fourth connecting bar 21 on one side is fixedly connected with a second slider 22. One end of each fourth connecting bar 21 on the other side is fixedly connected with a third slider 23. The outer walls of the second slider 22 and the third slider 23 are both slidably connected to the inside of a fourth connecting block 24. A second connecting column 25 is fixedly connected between the two fourth connecting blocks 24. The outer wall of the fourth connecting block 24 is fixedly connected to one side of a plurality of stirring blocks 26.

[0036] Specifically, start the second motor 18. The output end of the second motor 18 drives the third connecting block 20 to start rotating through the first connecting column 19. The rotation of the third connecting block 20 drives the second slider 22 and the third slider 23 to slide inside the fourth connecting block 24 through the fourth connecting bar 21. This action drives the stirring block 26 on the outer wall of the fourth connecting block 24 to start rotating. These stirring blocks 26 are located inside the feeding hopper 4, and their rotational stirring can effectively break up the agglomerated maleic anhydride. The effect of this breaking treatment prevents the accumulation of agglomerated maleic anhydride inside the feeding hopper 4, thereby avoiding blockage. By improving the fluidity of maleic anhydride in the feeding hopper 4, this design not only solves the current blockage problem but also ensures the stability and reliability of the device during long-term operation.

[0037] Working principle: During the operation of the maleic anhydride circulating feeding device, when the maleic anhydride particles are put into the upper hopper 4, the motor 16 is started, and the output end of the motor 16 is used to drive the gear 7 to rotate, and the gear 7 is rotated to drive the turntable 9 to rotate through the rack 8, and the slider 10 is used to support the turntable 9. The turntable 9 rotates and drives the connecting block 12 to rotate through the connecting bar 11, thereby driving the connecting block 2 16 to rotate through the connecting bar 2 13, and the connecting bar 3 15 is used to limit one side of the connecting block 2 16, so that the connecting block 2 16 rotates with the connecting bar 3 15 as the center of the circle, and the size of the discharge port at the bottom of the upper hopper 4 is adjusted in a targeted manner by adjusting the rotation angle of the connecting block 2 16. , so that the discharge speed matches the speed of other production processes to avoid affecting product production and enhance the practicability of the equipment. When the maleic anhydride circulation feeding device is blocked, start the motor 2 18, and use the output end of the motor 2 18 to drive the connecting block 3 20 to rotate through the connecting column 1 19. The connecting block 3 20 rotates through the connecting strip 4 21 to drive the slider 2 22 and the slider 3 23 to slide inside the connecting block 4 24, thereby driving the stirring block 26 on the outer wall of the connecting block 4 24 to rotate. The stirring block 26 is used to rotate and stir the maleic anhydride in the upper hopper 4, so that part of the agglomerated maleic anhydride is broken up to prevent the agglomerated maleic anhydride from piling up and causing blockage, thereby improving the discharge efficiency of the upper hopper 4 and providing convenience for product production.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
