Description

Technical Field

[0001] The utility model relates to the technical field of biomass fuel raw material mixing, in particular to a raw material mixing device for biomass fuel processing. Background Art

[0002] Biomass fuel refers to the burning of biomass materials as fuel. Biomass fuel raw materials can come from a variety of different biological materials, such as straw, wood waste, agricultural residues, animal manure, etc. These raw materials may differ in physical properties (such as density, particle size, moisture, etc.) and chemical composition. In order to obtain uniform biomass fuel, these different raw materials need to be mixed together. The mixing device can mix different types of raw materials in a certain proportion to optimize the combustion performance of the fuel and ensure the quality and production efficiency of the biomass fuel.

[0003] The raw materials of existing biomass fuels may contain large and uneven particles, and the mixing device is not easy to fully mix the large particle raw materials with other fine particle raw materials during the mixing process, resulting in poor mixing uniformity. In addition, the raw materials with larger particle sizes may cause incomplete combustion, reducing the calorific value and combustion efficiency of the fuel.

[0004] For example, a stirring device for biomass fuel processing disclosed in announcement number CN211886403U, the raw materials in this patent are not crushed or otherwise pre-treated before entering the mixing box. If there are large particles or uneven materials in the raw materials, if they enter the mixing box directly without being crushed, the stirring rod may encounter resistance during the stirring process, reducing the stirring efficiency, which will directly affect the stirring effect and fuel quality. At the same time, if there are large particles or hard materials in the raw materials, these materials may cause additional wear on the stirring device during the stirring process, shortening the service life of the equipment.

[0005] Therefore, it is necessary to invent a raw material mixing device for biomass fuel processing to solve the above problems. Utility Model Content

[0027] A large gear 9 and a small gear 11 are provided on the outside of the crushing box 6. There are two small gears 11. A No. 2 motor 8 is provided on one side of the large gear 9. The large gear 9 is connected to the output end of the No. 2 motor 8. The large gear 9 is arranged between the two small gears 11. The large gear 9 and the two small gears 11 are meshed. A No. 1 crushing roller 10 is fixedly connected to one side of the large gear 9. One side of the two small gears 11 is respectively fixedly connected with a No. 2 crushing roller 12. There are two No. 2 crushing rollers 12. The No. 1 crushing roller 10 is arranged between the two No. 2 crushing rollers 12. The shaft end of the No. 1 crushing roller 10 is rotatably connected to the inner wall of the crushing box 6, and the shaft ends of the two No. 2 crushing rollers 12 are rotatably connected to the inner wall of the crushing box 6.

[0028] The gear system in the crushing box 6 consists of a large gear 9 and two small gears 11. The large gear 9 is driven to rotate by the No. 2 motor 8, which in turn drives the two small gears 11 to rotate. The large gear 9 drives the two small gears 11 to rotate synchronously. The meshing transmission between the large gear 9 and the small gears 11 realizes the synchronous rotation of the No. 1 crushing roller 10 and the No. 2 crushing roller 12. The raw materials are crushed by the relative rotation of the No. 1 crushing roller 10 and the No. 2 crushing roller 12, forming a three-layer roller crushing structure to ensure that the raw materials are evenly and fully crushed in the crushing box 6.

[0029] The filter plate 13 is arranged inside the mixing box 3 and above the agitator 5. There is a certain distance between the bottom surface of the filter plate 13 and the agitator 5. The side wall of the pusher plate 15 is connected to the output end of the cylinder 14. The bottom surface of the pusher plate 15 contacts the top surface of the filter plate 13. The cleaning brush 16 is a soft brush. The cleaning brush 16 penetrates into the hole of the filter plate 13. The discharge port of the filter plate 13 is connected to the feed port of the guide plate 17, and the guide plate 17 is designed to be inclined.

[0030] A certain distance is maintained between the filter plate 13 and the agitator 5 to prevent the agitator 5 from interfering with the filter plate 13 during operation. The main function of the filter plate 13 is to screen the crushed raw materials so that the raw materials with appropriate particle size pass through the filter plate 13 and enter the mixing area of ​​the agitator 5. In order to clean the raw materials that may be accumulated on the filter plate 13, the cylinder 14 drives the pusher plate 15 to move back and forth above the filter plate 13, and the raw materials accumulated on the filter plate 13 can be pushed to the guide plate 17 for discharge. When the pusher plate 15 moves, the cleaning brush 16 penetrates into the holes of the filter plate 13 to remove the residue in the holes, thereby maintaining the smooth flow and screening effect of the filter plate 13. At the same time, the inclined guide plate 17 uses gravity to accelerate the sliding and collection of the raw materials, and continues to pour them into the crushing box 6 for crushing the raw materials.

[0031] Working principle of this utility model:

[0032] Refer to the instruction manual Figure 1-5When using the utility model, first, the biomass fuel raw materials are put into the crushing box 6 through the feed hopper 7, and the No. 2 motor 8 is started. The No. 2 motor 8 drives the large gear 9 to rotate, and the large gear 9 drives the two small gears 11 to rotate synchronously, thereby making the No. 1 crushing roller 10 and the No. 2 crushing roller 12 rotate relative to each other to crush the raw materials. The crushed raw materials fall from the crushing box 6 and are screened by the filter plate 13. Only the raw materials with appropriate particle size pass through the holes of the filter plate 13 and enter the mixing box 3. The No. 1 motor 4 is started and the No. 1 motor 4 drives the agitator. 5 rotates inside the mixing box 3 to efficiently mix the screened raw materials to ensure the uniformity of the raw materials. When too much raw materials are piled up on the filter plate 13, the cylinder 14 drives the push plate 15 to move and push the uncrushed raw materials on the filter plate 13 to the guide plate 17. At the same time, the cleaning brush 16 penetrates into the holes of the filter plate 13 to clean the residue in the holes. Since the guide plate 17 is designed in an inclined state, the raw materials can slide smoothly to the collection area. The staff then continues to put the collected large particles into the crushing box 6 for further crushing.
