It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a raw material mixing device for lignin, such as... Figure 1-4 As shown, the raw material mixing device for lignin includes: a base plate 1, with a mixing tank 2 mounted on the top of the base plate 1 for mixing lignin raw materials; a support 3 fixedly installed inside the mixing tank 2, with a first spiral rod 4 rotatably mounted on the support 3, and a stirring frame 5 fixedly installed at the bottom end of the first spiral rod 4 for stirring and mixing the lignin raw materials; a dispersing screen 6 fixedly installed inside the mixing tank 2 for pre-dispersing the lignin raw materials; a feed hopper 7 fixedly connected to the top of the mixing tank 2; a scraping mechanism mounted on the mixing tank 2 and the base plate 1 for scraping off the lignin raw materials retained in the dispersing screen 6; and a discharge mechanism mounted on the mixing tank 2 for discharging the mixed lignin raw materials.

[0022] In this embodiment, the base plate 1 is located at the bottom of the device to stably support the entire device; the mixing tank 2 is set on top of the base plate 1 for mixing and processing lignin raw materials; it provides a closed space so that the raw materials can be fully mixed in it; the bracket 3 is fixedly installed inside the mixing tank 2 to support the first spiral rod 4. A stirring frame 5 is fixedly installed at the bottom end of the first spiral rod 4; through the rotation of the first spiral 4 and the stirring frame 5, the lignin raw materials are stirred and mixed, improving the mixing efficiency; through the action of the dispersing screen 6, the raw materials can be more evenly distributed when entering the mixing tank, thereby reducing the mixing time and improving the mixing effect; the feed hopper 7 is fixedly connected to the top of the mixing tank 2 for adding raw materials into the mixing tank; the scraping mechanism is set on the mixing tank 2 and the base plate 1 for scraping the lignin raw materials retained in the dispersing screen 6; through the movement of the scraping mechanism, the raw materials retained on the dispersing screen 6 can be effectively removed, thereby ensuring the normal operation of the dispersing screen 6; the discharge mechanism is set on the mixing tank 2 for discharging the mixed lignin raw materials.

[0023] In a further preferred embodiment of this utility model, the scraping mechanism includes: a rotating rod 8 rotatably installed inside the mixing tank 2, the bottom end of the rotating rod 8 passing through the dispersing screen 6 and fixedly connected to the first spiral rod 4 via a coupling; a connecting frame 9 fixedly installed on the rotating rod 8; a scraper 10 fixedly installed on the connecting frame 9 for scraping lignin raw materials retained in the dispersing screen 6; a mounting frame 11 fixedly installed on the base plate 1, on which a first motor 12 and a speed regulator 13 are fixedly installed, the output shaft of the first motor 12 being fixedly connected to the input shaft of the speed regulator 13 via a coupling, and a transmission rod 14 fixedly installed on the output shaft of the speed regulator 13 via a coupling; a first bevel tooth 15 and a second bevel tooth 16 respectively fixedly installed on the transmission rod 14 and on the rotating rod 8, the first bevel tooth 15 and the second bevel tooth 16 meshing with each other for driving the rotating rod 8 to rotate.

[0024] In this embodiment, the rotating rod 8 is rotatably installed inside the mixing tank 2, with its bottom end penetrating the dispersing screen 6 and fixedly connected to the first spiral rod 4 via a coupling. Thus, when the first spiral rod 4 rotates, the rotating rod 8 also rotates synchronously; this achieves linkage between the scraping mechanism and the stirring mechanism, reduces power source redundancy, and improves the overall efficiency of the device. The connecting frame 9 is fixedly installed on the rotating rod 8 to support and fix the scraper 10; providing a stable mounting platform for the scraper 10 and ensuring the normal operation of the scraping mechanism. The scraper 10 is fixedly installed on the connecting frame 9 to scrape away the lignin raw material retained in the dispersing screen 6; effectively removing the raw material retained on the dispersing screen 6, preventing clogging of the screen holes, and ensuring the normal operation of the dispersing screen 6. The mounting frame 11 is fixedly installed on the base plate 1 to support and fix the first motor 12 and the speed regulator 13; providing a stable mounting foundation for the power unit and ensuring the continuous and stable operation of the scraping mechanism. The first motor 12 serves as the power source, and its output shaft is fixedly connected to the input shaft of the speed regulator 13 via a coupling. The speed regulator 13 is used to adjust the speed of the output shaft, thereby achieving precise control of the scraping mechanism's speed. It provides a reliable power source and precise speed control, allowing the scraping mechanism to be flexibly adjusted according to actual needs. The transmission rod 14 is fixedly mounted on the output shaft of the speed regulator 13 and drives the rotating rod 8 to rotate through the meshing of the first bevel gear 15 and the second bevel gear 16. The scraping mechanism is powered by the first motor 12, and after speed regulation by the speed regulator 13, it drives the rotating rod 8 to rotate through the transmission rod 14, the first bevel gear 15, and the second bevel gear 16. The rotation of the rotating rod 8 drives the synchronous rotation of the connecting frame 9 and the scraper 10, thereby achieving the scraping and removal of lignin raw materials retained in the dispersing screen 6. This design not only improves the mixing efficiency of the raw materials but also ensures the normal operation of the dispersing screen 6, avoiding clogging of the screen holes. Simultaneously, the precise speed regulation function of the speed regulator 13 allows for flexible adjustment of the scraping mechanism's speed according to actual needs.

[0026] In this embodiment, the discharge mechanism achieves efficient and continuous discharge of the mixed lignin raw material through the coordinated action of the discharge valve 17, discharge cylinder 18, second screw rod 19, and second motor 20. When it is necessary to discharge the raw material, the discharge valve 17 is opened first, and then the second motor 20 is started. The output shaft of the second motor 20 drives the second screw rod 19 to rotate inside the discharge cylinder 18 through a coupling. As the second screw rod 19 rotates, the mixed raw material is continuously guided from one end of the discharge cylinder 18 to the other end, and finally discharged from the outlet of the discharge cylinder 18. This design not only improves the discharge efficiency but also ensures the continuity and uniformity of the raw material, providing convenience for subsequent processing.

[0027] In a further preferred embodiment of the present invention, a protective shell 21 is fixedly installed on the mounting bracket 11. The protective shell 21 is used to shield the first motor 12, the speed regulator 13, the transmission rod 14, the first bevel gear 15, and the second bevel gear 16.

[0028] In this embodiment, the protective shell 21 is cleverly designed and fixedly installed on the mounting bracket 11. It tightly wraps around key components such as the first motor 12, speed regulator 13, transmission rod 14, first bevel gear 15 and second bevel gear 16, preventing personnel from accidentally touching and injuring themselves during the operation of the components, which is beneficial to safety.

[0030] In this embodiment, the combined use of the support column 22 and the foot pad 23 provides stable and safe support for the entire device and effectively prevents safety hazards caused by ground slippage or wear.

[0031] In a further preferred embodiment of the present invention, a through hole is provided in the middle of the dispersing screen 6, and the through hole is adapted to the rotating rod 8.

[0032] In this embodiment, the through hole provides a channel for the rotating rod 8 to pass through the dispersing screen 6, so that the rotating rod 8 can be connected to the first spiral rod 4.

[0033] In a further preferred embodiment of the present invention, the bottom of the mixing tank 2 is symmetrically and fixedly installed with support legs, and the bottom end of the support legs is fixedly connected to the base plate 1.

[0034] In this embodiment, the symmetrical installation of the support legs 24 at the bottom of the mixing tank 2 and their fixed connection with the base plate 1 further enhance the structural strength and stability of the entire device.

[0035] In summary, the base plate 1 provides stable support for the entire device, ensuring operational stability; the mixing tank 2 provides a closed space, allowing the lignin raw materials to be fully mixed; the bracket 3 supports the first spiral rod 4, which rotates with the stirring frame 5, efficiently stirring and mixing the raw materials; the dispersing screen 6 ensures uniform distribution of the raw materials upon entering the mixing tank, reducing mixing time and improving mixing efficiency; the scraping mechanism, through the synchronous rotation of the rotating rod 8, connecting frame 9, and scraper 10, effectively scrapes away the lignin raw materials retained in the dispersing screen 6, preventing screen clogging; the first motor 12 provides power, the speed regulator 13 precisely adjusts the speed, and through the transmission rod 14, the first bevel gear 15, and the second bevel gear 16, flexible adjustment of the scraping mechanism is achieved; the discharge mechanism, through the coordinated action of the discharge valve 17, discharge cylinder 18, second spiral rod 19, and second motor 20, achieves efficient and continuous discharge of the mixed lignin raw materials.
