[0002] Biomass pellets are cold-formed and compacted by rollers and ring dies at room temperature using crushed biomass straw, forestry waste and other raw materials. The density of the raw materials is generally 0.1-0.13t / m3, and the density of the formed pellets is 1.1-1.3t / m3, which is convenient for storage and transportation, and greatly improves the combustion performance of biomass. According to the definition of the International Energy Agency (IEA), biomass refers to various organisms formed through photosynthesis, including all plants, animals and microorganisms. Biomass energy is the energy form of solar energy stored in biomass in the form of chemical energy. It has always been one of the important energy sources for human survival. It is the fourth largest energy source after coal, oil and natural gas, and occupies an important position in the entire energy system.

[0003] The temperature of the newly produced biomass pellets is too high to be directly bagged and needs to be cooled by a cooler. Existing biomass pellet coolers generally blow cold air directly onto the biomass pellets to cool them down, which can easily cause the biomass pellets to cool suddenly and crack on the surface, affecting the quality of the finished product.

[0021] A first motor 27 is fixedly provided on the outer wall of one side of the cooling box 11, and the end of the output shaft of the first motor 27 is fixedly provided at one end of the rotating rod 191; the rotating rod 191 is driven by the first motor 27, because the first bevel gear 2 is fixedly provided on the rotating rod 191, and the second bevel gear 21 and the third bevel gear 24 are respectively meshed with the first bevel gear 2, when the first bevel gear 2 rotates, it will drive the second bevel gear 21 and the third bevel gear 24 to rotate.

[0022] An exhaust port 3 is formed through one end of the cooling box 11 away from the first motor 27, and a fixed block 31 is fixedly provided near the exhaust port 3 of the cooling box 11, and symmetrically distributed exhaust fans 32 are fixedly provided inside the fixed block 31; the exhaust fan 32 discharges the heat in the cooling box 11 and forms a negative pressure in the cooling box 11, allowing external air to enter through the air inlet 46.

The tooth plate 4 and the rack 41 are meshed with each other, and a discharge plate 42 is fixedly provided at one end of the rack 41. A slider 43 is fixedly provided on the lower surface of the base 1, and the end of the discharge plate 42 close to the rack 41 is slidably provided on the slider 43.

[0024] The discharge plate 42 is provided with a plurality of air inlet holes 46 which are distributed at equal intervals. The size of the air inlet holes 46 is smaller than the biomass particles.

[0026] Working principle: When in use, align the feed port 14 with the discharge port of the biomass pellet production machine, and the material pellets will enter through the feed hopper 13. Subsequently, the biomass pellets in the feed hopper 13 will enter the cooling box 11 through the feed hole 12 under the action of gravity. The biomass pellets entering the cooling box 11 will fall on the rotating cloth block 23, and will be evenly scattered in the cooling box 11 as the cloth block 23 rotates. The biomass pellets entering the cooling box 11 will be stirred by the rake rod 26 to make the surface of the accumulated biomass pellets flat;

[0027] When the biomass particles in the cooling box 11 need to be cooled, the staff member turns the handle 16 again to reset the baffle 15, blocks the feed hole 12, and stops feeding into the cooling box 11. Then, under the action of the exhaust fan 32, the heat in the cooling box 11 is discharged and a negative pressure is formed in the cooling box 11. When the cooling box 11 is in a negative pressure state, the external air enters the cooling box 11 from the air inlet 46, and is discharged from the exhaust port 3 again after absorbing the heat, forming an air circulation;

[0028] When the biomass particles in the cooling box 11 are cooled and need to be discharged, the staff can start the second motor 49 to drive the tooth plate 4. Since the tooth plate 4 and the rack 41 are meshed with each other, when the tooth plate 4 rotates, it will drive the two racks 41 to move in different directions. Since the discharge plate 42 is fixed on the rack 41, when the rack 41 moves, the discharge plate 42 will move with it. Therefore, the two discharge plates 42 can be moved closer or farther away by controlling the tooth plate 4 to rotate in different directions. When the two discharge plates 42 are far away from each other, discharge can be carried out.
