[0024] like Figure 1-5 In the present invention, a biomass pellet fuel conveying device with a pellet cooling function includes a conveying structure 1, wherein the conveying structure 1 is provided with a feeding structure 2 and multiple sets of air-cooling structures 3.

[0025] The conveying structure 1 includes a symmetrically arranged support frame 4, on which are provided mutually cooperating conveying rollers 5, on which are provided material gathering sections 6, on which are provided mutually cooperating conveying rollers 5 and a cooperating conveying belt 11, on which are provided material gathering troughs 12 that cooperate with material gathering sections 6, the conveying rollers 5 are connected to the output end of the drive motor 9, and the drive motor 9 is connected to the support frame 4 through a fixed base 10.

[0026] In a preferred embodiment, the feeding structure 2 includes a wide-mouth feeding trough 15, which is connected to the support frame 4 via a support plate 16. Multiple sets of guide inclined plates 17 are arranged in a zigzag pattern inside the wide-mouth feeding trough 15, and a guide groove 18 is provided at the discharge end of the wide-mouth feeding trough 15.

[0027] In a preferred embodiment, the air-cooled structure 3 includes a frame 19 mounted on a support frame 4. The frame 19 is connected to the fan structure 21 via a mounting bracket 20. An air guide shroud 23 is fitted onto the frame 19. The air guide shroud 23 is connected to the top of an air guide plate 25 via a rotating shaft 24. An adjusting shaft 26 is provided at the bottom of the air guide plate 25. The adjusting shaft 26 cooperates with an adjusting groove 27 provided on the air guide shroud 23. Fasteners 28 for fixing the position are provided on the adjusting shaft 26.

[0028] In a preferred embodiment, the frame 19 is provided with a filter screen 22.

[0029] In a preferred embodiment, the conveying roller 5 is symmetrically provided with limiting grooves 7, which are matched with limiting strips 13 provided on the conveyor belt 12 for limiting.

[0030] In a preferred embodiment, the two ends of the conveyor roller 5 are symmetrically provided with limiting baffles 8 that cooperate with the conveyor belt 11.

[0031] In a preferred embodiment, baffles 14 are symmetrically provided on both sides of the conveyor belt 11.

[0032] Example 2:

[0033] like Figure 1-5 In the design, the support frame 4 is made of high-strength metal material and is symmetrically arranged on the ground. The conveyor rollers 5 are installed on the support frame 4 and are wear-resistant. The material gathering section 6 is fixed to the middle of the conveyor roller 5 by welding and has an arc-shaped protrusion on its surface. The conveyor belt 12 is made of high-temperature resistant and wear-resistant rubber material. The material gathering trough 12 is pressed onto the surface of the conveyor belt by a mold and matches the shape of the material gathering section 6. The drive motor 9 is a three-phase asynchronous motor with appropriate power. Its output shaft is connected to the conveyor roller 5 by a coupling. The symmetrically arranged limiting grooves 7 on the conveyor roller 5 are 5mm deep and 8mm wide and cooperate with the limiting strips 13 on the conveyor belt 12 that are 5mm thick and 8mm wide. The limiting baffles 8 at both ends of the conveyor roller 5 are 30mm high and are fixed to both ends of the conveyor roller by bolts. The material blocking strips 14 on both sides of the conveyor belt 12 are 20mm high and are glued to both sides of the conveyor belt.

[0034] Example 3:

[0035] like Figure 1-5 The working principle of this utility model is as follows: biomass pellet fuel is poured into the feed inlet of the wide-mouth feed trough 15. Under the action of gravity, the fuel falls and comes into contact with the guide inclined plates 17 arranged in a zigzag pattern. The fuel continuously changes its direction of movement on the guide inclined plates 17, thereby achieving dispersion and avoiding accumulation. After being guided by the guide inclined plates 17, the fuel falls accurately from the discharge port of the guide trough 18 into the aggregate trough 12 of the conveyor belt 12.

[0036] When the drive motor 9 starts, it drives the conveyor roller 5 to rotate through the output end, thereby causing the conveyor belt 12 fitted on the conveyor roller 5 to run. Due to the limiting strip 13 on the conveyor belt 12 and the limiting groove 7 on the conveyor roller 5, as well as the limiting baffles 8 at both ends of the conveyor roller 5, the conveyor belt 12 can run stably without deviation. The baffle strips 14 on both sides of the conveyor belt 12 prevent fuel from scattering from both sides during the conveying process.

[0037] When the fan structure 21 is started, the generated airflow passes through the filter screen 22 on the frame 19 to filter impurities and then enters the air guide shroud 23. By adjusting the angle of the air guide plate 25, the adjusting shaft 26 slides in the adjusting groove 27. After adjusting to a suitable angle, it is fixed with fasteners 28, which guides the airflow to the biomass pellet fuel on the conveyor belt for cooling. The cooled fuel is then transported to the subsequent processing stage as the conveyor belt 12 runs.

[0038] The beneficial effects of this utility model are: rapid air cooling during material receiving and conveying, preventing the finished biomass pellet fuel from becoming damp and absorbing water, thus ensuring product quality; material gathering and collection during conveying, stable and precise conveying connection, and materials are not easy to roll and fall during conveying; guiding rolling during feeding, which not only avoids material accumulation, but also reasonably disperses the material, facilitates air cooling and is highly practical.
