Description

Technical Field

[0001] This utility model relates to the field of biomass pellet sorting technology, and in particular to a sorting device based on biomass pellet fuel production. Background Technology

[0002] Biomass pellet sorting refers to the process of classifying and screening pellet fuels made from various organic materials (such as wood waste, crop straw, bagasse, rice husks, grasses, seed shells, etc.) after processing. This process ensures the quality and consistency of biomass pellets, thereby improving their efficiency and reliability as a clean energy source.

[0003] Chinese invention patent application CN107377395B discloses a device for improving the sorting efficiency of strip-shaped biomass pellets. This patent includes a conveyor belt I, with a sorting device at the starting end of conveyor belt I. The sorting device includes an adjustment assembly and a pair of conveyor belts II. The adjustment assembly includes a pair of support plates, with a rotating shaft positioned between the support plates. The conveyor belts II are located between conveyor belt I and the adjustment assembly, and the distance between opposite faces of the conveyor belts II is less than the distance between opposite faces of the support plates. The strip-shaped biomass pellets to be sorted are placed on the rotating shaft. As the shaft rotates, the biomass pellets are repositioned. When the biomass pellets move onto conveyor belts II, those that are not of the correct length fall from between the fingers of conveyor belts II. This sorting system can easily and quickly sort out defective biomass pellets, improving work efficiency, reducing worker workload, and preventing missed sorting.

[0004] In the existing technology, to achieve the screening of biomass pellets, biomass pellets of different sizes need to be placed on the same sieve plate for screening. This screening device has problems such as a single screening diameter and insufficient screening fineness. Multiple screenings are required to achieve the desired effect, so it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sorting device based on biomass pellet fuel production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A sorting device based on biomass pellet fuel production includes a sorting box and further includes:

[0008] The stepped sorting structure includes a stepped plate, and the flat part of the stepped plate is respectively provided with a first screen hole, a second screen hole, a third screen hole and a fourth screen hole.

[0009] A further technical solution involves setting up equal-height enclosures around the stepped plate, with a material pipe installed on one side of each equal-height enclosure.

[0010] A further technical solution involves providing storage boxes at the bottom corresponding positions of the first, second, third, and fourth sieve holes.

[0011] Further technical solutions also include:

[0012] The vibrating sorting assembly includes fixed plates docked to both sides of a stepped plate. A guide rod is movably installed inside the fixed plate, and a movable plate is installed on the other side of the guide rod. A spring is installed between the fixed plate and the movable plate on the guide rod, and a baffle is installed on the outside of the fixed plate and the movable plate on the guide rod.

[0013] A further technical solution is that the vibration sorting assembly includes a limiting rod that is movably mounted between the fixed plate and the movable plate.

[0014] A further technical solution includes a motor in the vibratory sorting assembly. The output end of the motor is equipped with a rotating shaft, and a pendulum is mounted on the rotating shaft. The pendulum rests on the bottom of the movable plate.

[0015] A further technical solution involves providing a motor slot on one side of the sorting box, with the motor installed inside the slot.

[0016] Compared with the prior art, this utility model provides a sorting device based on biomass pellet fuel production, which has the following beneficial effects:

[0017] With its stepped sorting structure, this device employs a unique stepped screen plate design during use. Different diameter screen holes are pre-set on the flat parts of the steps. When the material enters the device from the hopper, it will be refined by being screened separately at different screen holes. At the same time, the downward force of gravity on the material will also be used to achieve an auxiliary screening effect.

[0018] The structure uses a vibrating sorting device to create a resonant structure consisting of guide rods and springs around the stepped plate. A motor controls a pendulum to strike the resonant structure, which vibrates the screen plate, thus making the sorting process more thorough. Attached Figure Description

[0025] Example 1: Refer to Figure 1 - Figure 4 A sorting device based on biomass pellet fuel production includes a sorting box 1, a storage box 9 inside the sorting box 1 for collecting sorted materials, and further includes:

[0026] A stepped sorting structure 2 includes stepped plates. Materials on the surface of the stepped plates move downwards step by step, and are then screened on different levels of screen openings. The planar portion of the stepped plates is provided with a first screen opening 4, a second screen opening 5, a third screen opening 6, and a fourth screen opening 7.

[0027] The sorting device based on biomass pellet fuel production includes a stepped plate surrounded by equal-height baffles to prevent materials from falling off during sorting. A material pipe 8 is connected to one side of each equal-height baffle.

[0028] The sorting device based on biomass pellet fuel production has a storage box 9 at the bottom of the first screen hole 4, the second screen hole 5, the third screen hole 6 and the fourth screen hole 7, which is used to collect the sorted materials.

[0029] The sorting device based on biomass pellet fuel production further includes:

[0030] The vibration sorting assembly 3 includes fixed plates 10 docked to both sides of a stepped plate, which can drive the entire stepped plate to vibrate up and down. A guide rod 11 is movably arranged inside the fixed plate 10, connecting the fixed plate 10 and a movable plate 12. A movable plate 12 is located on the other side of the guide rod 11, receiving the rotation of the pendulum 16 and transmitting the vibration to the fixed plate 10 and the stepped plate via a spring 14. A spring 14 is located between the fixed plate 10 and the movable plate 12 on the guide rod 11, and a baffle 13 is located on the outside of the guide rod 11 on both sides of the stepped plate 10 and the movable plate 12.

[0031] The sorting device based on biomass pellet fuel production includes a vibration sorting component 3 comprising a limiting rod 15 movably installed between a fixed plate 10 and a movable plate 12. The limiting rod 15 is used to position the device inside the sorting box 1.

[0032] The sorting device based on biomass pellet fuel production includes a vibrating sorting component 3, which further includes a motor 18. The motor 18 drives a pendulum 16 to rotate via a rotating shaft 17, thereby impacting a movable plate 12 to achieve a vibration effect. The output end of the motor 18 is equipped with a rotating shaft 17, and the pendulum 16 is mounted on the rotating shaft 17. The pendulum 16 rests on the bottom of the movable plate 12.

[0033] The sorting device based on biomass pellet fuel production has a motor slot 19 on one side of the sorting box 1, and the motor 18 is installed inside the motor slot 19.

[0034] Working principle:

[0035] In the actual design process of this utility model, to avoid the following defects existing in the prior art: "In the prior art, to achieve the screening of biomass pellets, biomass pellets of different sizes need to be placed on the same sieve plate for screening. This screening device has problems such as a single screening diameter and insufficient screening fineness, requiring multiple screenings to achieve the desired effect, thus requiring improvement." Therefore, a stepped sorting structure 2 and a vibrating sorting structure 3 are specifically proposed:

[0036] Stepped sorting structure 2:

[0037] This structure addresses the problem of limited sorting apertures in traditional sorting structures by proposing a stepped screening plate. Different aperture sizes are set on different planes of the stepped plate. Biomass materials fall naturally onto the surface of the stepped plate, achieving multiple screening effects on the surfaces of the different aperture sizes, thus greatly improving sorting efficiency.

[0038] Vibration sorting component 3;

[0039] To further improve the sorting speed, a fixed plate 10 is fixed to the side of the stepped plate, and a movable plate 12 is movably mounted via a guide rod 11. A tension spring 14 connects the movable plate 12 and the fixed plate 11, and a baffle 13 limits the vibration positions of the movable plate 12 and the fixed plate 11 at both ends. The pendulum 16 on the rotating shaft 17 is rotated by the motor 18, thereby impacting the movable plate 12. The vibration of the surface of the movable plate 12 is transmitted to the surface of the fixed plate 11 through the spring 14, thus achieving a synchronous vibration effect of the stepped sorting assembly and increasing sorting efficiency.
