[0002] Biomass energy is a highly efficient and clean energy source that is burned from biomass materials. It mainly comes from agricultural and forestry waste, such as straw, sawdust, bagasse, rice bran, etc. No additives or binders are added to biomass fuel during the production process. The diameter of biomass particles is generally 6 to 10 mm. Biomass particles need to be pre-mixed with a variety of powdered raw materials during production. Mixers are usually used to complete the mixing of raw materials. Mixers generally use a rotating stirring method.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-6 A mixer for biomass energy includes a material barrel 1, a bracket 2 and a discharge port 3. The upper end of the bracket 2 is fixedly connected with a cross fixing rod 4, and the upper surface of the cross fixing rod 4 is fixedly connected with a motor bin 5. A driving motor 6 is arranged inside the motor bin 5, and the output end of the driving motor 6 is connected with a staggered rotating stirring device. A sealing device is arranged above the discharge port 3.

[0026] It can be seen from the above structure that by setting the barrel 1, bracket 2, discharge port 3, cross fixing rod 4, motor bin 5, drive motor 6, staggered rotating stirring device and sealing device, etc., first pour the raw material into the staggered rotating stirring device, start the drive motor 6 to form a staggered stirring motion mode in the staggered rotating stirring device, so that the flow mixing motion of the powder particles in the raw material is more complex and diversified. This helps to increase the collision and friction between the particles, promote the uniform mixing of the powder, and thus improve the work efficiency, while the sealing device can block the discharge port 3 to prevent the leakage of the raw material. After the mixing is completed, open the sealing device, and the mixed raw material will automatically flow out of the barrel 1.

[0027] Furthermore, the staggered rotating stirring device includes an active rotating shaft 7 fixedly connected to the output end of the driving motor 6, and the other end of the active rotating shaft 7 extends to the interior of the barrel 1, the side wall of the active rotating shaft 7 is fixedly connected to multiple groups of active stirring blades 8, and the side wall of the motor bin 5 is provided with a rotating groove 9, the side wall of the active rotating shaft 7 located on one side of the rotating groove 9 is fixedly connected to a driving gear 10, and the inner wall of the rotating groove 9 is fixedly connected to a supporting shaft 11, the side wall of the supporting shaft 11 is rotatably connected to a conversion gear 12, and the conversion gear 12 is meshed with the active gear 10, and the inner wall of the rotating groove 9 is rotatably connected to the driving gear 10. A driven gear 13 is provided, and the driven gear 13 is meshed with the conversion gear 12. The side wall of the driven gear 13 is fixedly connected with a silo 14. The inner wall of the barrel 1 is provided with an annular groove 15. The inner wall of the annular groove 15 is slidably connected with an annular slider 16. The side wall of the annular slider 16 is fixedly connected with the side wall of the silo 14. The side walls of the silo 14 located between the two adjacent groups of active stirring blades 8 are fixedly connected with driven stirring blades 17. A feeding port 18 is provided on the upper surface of the silo 14. The inner wall of the feeding port 18 is threadedly connected with a sealing cover 19. By arranging the drive motor 6, the active rotating shaft 7, and the barrel 1 , active stirring blade 8, rotating groove 9, supporting shaft 11, active gear 10, conversion gear 12, driven gear 13, annular slide groove 15, annular slider 16, silo 14, driven stirring blade 17, feeding port 18 and sealing cover 19 are used together. When it is necessary to mix raw materials, first pour the raw materials into silo 14 through feeding port 18, cover with sealing cover 19, then start driving motor 6, so that active rotating shaft 7 fixedly connected to the output end of driving motor 6 drives active stirring blade 8 to rotate forward to stir the raw materials in silo 14, and at the same time, active rotating shaft 7 drives active gear fixedly connected to the side wall 10 rotates forward, the active gear 10 will drive the conversion gear 12 to rotate in the reverse direction, and then the driven gear 13 meshing with the conversion gear 12 will rotate in the opposite direction at the same time, and the silo 14 fixedly connected to the side wall of the driven gear 13 will rotate in the opposite direction in the barrel 1 along the annular slide 15 through the annular slider 16, so that the driven stirring blade 17 rotates in the opposite direction, because the driven stirring blade 17 is located in the middle position of the two adjacent groups of active stirring blades 8, and then the active stirring blade 8 and the driven stirring blade 17 will rotate alternately, and then form a staggered rotation motion mode, making the movement of the powder particles in the mixing container more complex and diversified. This helps to increase the collision and friction between the particles and promote the uniform mixing of the powder. During the mixing process, due to the difference in the physical properties of the powder, agglomeration and stratification are prone to occur, resulting in uneven mixing, and staggered stirring and mixing can effectively disperse these agglomerations and stratifications by changing the stirring method, so that the powder is more evenly distributed in the mixing container, thereby improving the mixing efficiency.

The T-shaped latch 23 can fix the blocking slider 21. After the raw materials are mixed, the T-shaped latch 23 can be taken out to pull the blocking slider 21 to slide the blocking slider 21 out of the blocking chute 20. After that, the mixed raw materials will automatically slide out of the discharge port 3, which is convenient and quick.

[0029] Furthermore, leakage ports 25 are provided on the side walls of the active stirring blades 8 and the driven stirring blades 17; by providing the leakage ports 25, the raw materials in the silo 14 will slide out from the leakage ports 25 of the active stirring blades 8 and the driven stirring blades 17 during the stirring process, making the flow pattern of the mixed raw materials in the silo 14 more complex and diverse, thereby further improving the mixing efficiency.
