[0024] Embodiment 1: Please refer to Figures 1 - 5 , a mixer with a shaft - seal closing device, including a base 1. A support frame 3 is fixedly connected to the top end of the base 1. A mixing tank 5 is arranged inside the support frame 3. Shaft - seal closing structures are arranged on both sides of the top end of the mixing tank 5;

[0025] The shaft - seal closing structure includes a rack 8, a drive motor 10, and a rotating shaft 12. Servo motors 20 are installed on both sides of the rear end of the top of the mixing tank 5. The output end of the servo motor 20 is fixedly connected to a rotating shaft 12. A gear 9 is fixedly connected to the outside of the rotating shaft 12. Racks 8 are arranged on both sides of the top end of the mixing tank 5. A sealing block 13 is fixedly connected to one side near the middle of the bottom end of the rack 8. Sealing rings 19 are respectively fixedly connected to the bottom end of the rack 8 and the inner side wall of the sealing block 13. A support plate 7 is arranged at the top end of the mixing tank 5. A reserved groove 14 is opened at the top end inside the mixing tank 5;

[0026] A drive motor 10 is installed at the top end of the support plate 7. The output end of the drive motor 10 is fixedly connected to a connecting shaft 11. Stirring rods 15 are fixedly connected to both sides of the connecting shaft 11. A stirring frame 16 is installed between the stirring rods 15. The drive motor 10 is arranged at the top of the rack 8, and the rack 8 and the drive motor 10 cooperate with each other;

[0027] Specifically, as Figure 1 、Figure 2 and Figure 3 As shown in Figure 3 , when it is necessary to close the rack 8 to seal the top outside the connecting shaft 11, the servo motor 20 is started. The servo motor 20 drives the gear 9 to rotate through the rotating shaft 12, so that the gear 9 drives the sealing block 13 to move towards the middle through the rack 8, so as to close the rack 8 and make the sealing block 13 wrap the top outside the connecting shaft 11. The sealing ring 19 on the inner side wall of the sealing block 13 and the sealing ring 19 at the bottom end of the rack 8 can seal the top outside the connecting shaft 11, preventing the gas of the raw material from leaking out and the raw material from splashing.

[0028] Embodiment 2: Hydraulic cylinders 6 are installed on both sides of the top end of the support frame 3. The hydraulic cylinders 6 are installed on both sides of the bottom end of the support plate 7. A limiting telescopic rod 4 is fixedly connected to the left side between the base 1 and the support plate 7;

[0029] Specifically, as Figure 1 and Figure 4 shown, when the hydraulic cylinder 6 is started, the hydraulic cylinder 6 drives the support plate 7 to rise, so that the stirring assembly at the bottom end of the support plate 7 can rise out of the inside of the mixing tank 5. The stirring assembly rising out of the inside of the mixing tank 5 can facilitate the cleaning of the stirring assembly and prevent impurities from adhering to the stirring assembly and affecting the next use.

A valve 18 is arranged at the top of the front end of the discharge pipe 17. A limiting frame 2 is fixedly connected to the left side of the bottom end of the mixing tank 5. A limiting groove 21 is opened on the right side of the top end of the limiting frame 2. The bottom end of the discharge pipe 17 is arranged inside the limiting groove 21;

[0031] Specifically, as Figure 1 and Figure 5 shown, the hose 22 is arranged between the discharge pipes 17, which facilitates pulling the bottom end of the discharge pipe 17 to different positions, so as to facilitate discharging the raw material to a suitable position. The limiting groove 21 inside the limiting frame 2 can facilitate the support and limitation of the bottom end of the discharge pipe 17 to prevent the bottom end of the discharge pipe 17 from contacting the ground.

[0032] Working principle: When the utility model is in use, the hydraulic cylinder 6 is started. The hydraulic cylinder 6 drives the support plate 7 to descend, so that the stirring assembly descends into the interior of the mixing tank 5. After descending into the interior of the mixing tank 5, the servo motor 20 is started. The servo motor 20 drives the gear 9 to rotate through the rotating shaft 12, so that the gear 9 drives the sealing block 13 to move towards the middle through the rack 8, thereby closing the rack 8 and enabling the sealing block 13 to wrap around the top end of the connecting shaft 11. The sealing rings 19 on the inner side wall of the sealing block 13 and the sealing rings 19 at the bottom end of the rack 8 can seal the top end of the outer part of the connecting shaft 11, preventing the leakage of raw material gas and the splashing of raw materials. The hose 22 is arranged between the discharge pipes 17, which facilitates pulling the bottom end of the discharge pipe 17 to different positions, so as to conveniently discharge the raw materials to the appropriate positions. The limiting grooves 21 inside the limiting frame 2 can conveniently support and limit the bottom end of the discharge pipe 17, preventing the bottom end of the discharge pipe 17 from contacting the ground. After discharging the materials, the hydraulic cylinder 6 is started again. The hydraulic cylinder 6 drives the support plate 7 to rise, so that the stirring assembly at the bottom end of the support plate 7 rises out of the interior of the mixing tank 5. The stirring assembly rising out of the interior of the mixing tank 5 can facilitate the cleaning of the stirring assembly, preventing impurities from adhering to the stirring assembly and affecting the next use.
