Description

Technical Field

[0001] The utility model relates to the technical field of biomass particle distribution, in particular to a biomass particle distribution device. Background Art

[0002] Biomass pellets are produced by cold-dense molding of crushed biomass straw, forestry waste and other raw materials using rollers and ring dies at room temperature. During the production of biomass pellets, a material separation device is required to screen the biomass pellets according to different sizes.

[0003] A Chinese patent with publication number CN111482369A discloses a discharging and sorting device for preparing biomass particles, including a device body, a sorting rod fixedly installed at the upper end of the device body, a rotating wheel fixedly installed inside the sorting rod, a dust removal device fixedly installed at the middle end of the device body, and a dust suction drum fixedly installed on the outside of the dust removal device. The adjacent spacing of the right half of the sorting rod is smaller than that of the left half, so that when the biomass particles are on the right side of the sorting rod, the biomass particles with a volume smaller than the standard size will pass through the gap between the sorting rods and move downward, and be discharged from the inside of the device body through the first discharging plate. When the biomass particles are on the left side of the sorting rod, the biomass particles with a volume larger than the standard size will not be able to pass through the gap between the sorting rods and move downward, and then be discharged from the inside of the device body through the second discharging plate, so that the biomass particles of unqualified size can be sorted out at one time, thereby improving the overall product quality of the biomass particles.

[0004] In the process of screening biomass particles in the existing material distribution device, the biomass particles fall directly onto the guide plate after screening. There is no buffer component on the guide plate, which easily causes damage to the biomass particles and results in poor protection of the biomass particles. Therefore, a biomass particle distribution device is proposed to address the above problems. Utility Model Content

There is no buffer component on the guide plate, which can easily cause damage to the biomass particles, resulting in damage to the biomass particles. The protection is poor. By guiding the biomass particles into the upper hopper 20, and then pouring them into the screening drum 18 from the upper hopper 20, the motor 16 is operated to drive the rotating shaft 15 to rotate, the rotating shaft 15 drives the connecting frame 17 to rotate, and the connecting frame 17 drives the screening drum 18 to rotate.

At the same time, the distance between the first guide plate 6 and the fixed plate 3 changes, and the first guide plate 6 drives the moving rod 12 to move in the vertical direction. The moving rod 12 drives the piston block 11 to move in the slide groove 10 of the damping rod 9. Friction resistance is generated between the outer wall of the piston block 11 and the inner wall of the slide groove 10. The friction resistance can consume the kinetic energy of the spring 8.

This structure can buffer the biomass particles, avoid damage caused by the biomass particles falling, and is beneficial to improving the protection of the biomass particles.

The motor 16 is operated to drive the rotating shaft 15 to rotate, and the rotating shaft 15 drives the connecting frame 17 to rotate. The connecting frame 17 drives the screening drum 18 to rotate, and the screening drum 18 drives the biomass particles inside it to roll. The small-diameter biomass particles fall from the rod gaps of the screening drum 18 onto the first guide plate 6, and then roll along the first guide plate 6 into the first collecting box 21, while the large-diameter biomass particles slide out obliquely downward along the screening drum 18, fall onto the second guide plate 13, and roll along the second guide plate 13 into the second collecting box 22; when the biomass particles fall to During the process of the first guide plate 6 and the second guide plate 13, the biomass particles fall onto the first guide plate 6. Under the action of the gravity of the biomass particles, the first guide plate 6 presses the spring 8 on the bottom side, and the spring 8 undergoes elastic deformation and stores energy, thereby achieving buffering of the biomass particles.
