Description

Technical Field

[0002] Biomass pellet fuel is a renewable fuel made from biomass resources such as crop straw and forestry waste, and it is environmentally friendly and sustainable. Its advantages include: Renewability: Biomass pellet fuel is derived from renewable resources and does not damage the environment. Clean Energy: It produces little smoke and dust during combustion, with zero carbon dioxide emissions, meeting low-carbon and environmental protection requirements. Fertilizer Use: The ash from combustion can be used as fertilizer, promoting plant growth and forming a virtuous cycle. Stable Demand: In specific scenarios such as power supply and heating, the demand for biomass pellet fuel is relatively stable. During storage, attention must be paid to temperature and humidity to ensure fuel performance and effectiveness.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figure 1-4As shown, a pellet biomass fuel combustion testing device includes a combustion cylinder 1. A support plate 2 is fixedly connected to the outside of the combustion cylinder 1. Four first legs 3 are fixedly connected to the outside of the support plate 2. An mounting plate 4 is fixedly connected to the bottom of the first legs 3. Four second legs 5 are fixedly connected to the outside of the mounting plate 4. The inside of the mounting plate 4 is fixedly connected to the outside of the combustion cylinder 1. An intelligent control device 6 is fixedly connected to the top of the mounting plate 4. A mounting frame 7 is fixedly connected to the outside of the combustion cylinder 1. A feed cylinder 30 is fixedly connected to the top of the combustion cylinder 1. The inside of the feed cylinder 30 communicates with the inside of the combustion cylinder 1. A cover 31 is slidably connected inside the feed cylinder 30. A venting component is provided inside the combustion cylinder 1. The venting component includes... The device includes a first limiting ring 8 fixedly connected inside the combustion chamber 1, a first bearing plate 9 slidably connected to the outside of the first limiting ring 8, a connecting cylinder 10 fixedly connected to the bottom of the first bearing plate 9, an internal toothed ring 11 fixedly connected to the bottom of the connecting cylinder 10, a second limiting ring 12 slidably connected inside the internal toothed ring 11, the outside of the second limiting ring 12 fixedly connected to the inside of the combustion chamber 1, a ventilating cone 13 fixedly connected to the top of the first bearing plate 9, a sweeping plate 29 slidably connected to the top of the first bearing plate 9, the end of the sweeping plate 29 fixedly connected to the inside of the combustion chamber 1, a second bearing plate 14 fixedly connected to the outside of the ventilating cone 13, and a third bearing plate 15 fixedly connected to the outside of the ventilating cone 13.

[0025] During operation, the first bearing plate 9 is supported by the first limiting ring 8, and the inner toothed ring 11 is supported by the second limiting ring 12. The first bearing plate 9 and the inner toothed ring 11 are connected together by the connecting cylinder 10. Then, the particles are supported by the first bearing plate 9, and the particles are supported by the second bearing plate 14 and the third bearing plate 15. At the same time, the particles can be spread apart by the ventilated cone 13, so that the inside of the particles will not be completely overlapped. The ventilated cone 13 can also allow air to pass through the inside of the particles, so as to ensure that the particles can burn more completely, thereby ensuring that the data of particle combustion can be more accurate.

[0026] The connecting cylinder 10 is equipped with an auxiliary component, which includes a collection hopper 16 rotatably connected inside the connecting cylinder 10. The top of the collection hopper 16 is slidably connected to the bottom of the first bearing plate 9, and a connecting plate 17 is fixedly connected to the outside of the collection hopper 16.

[0028] During operation, the particles are supported by the first support plate 9, the second support plate 14, the third support plate 15 and the ventilated cone 13. After the particles burn, the remaining ash falls into the connecting cylinder 10 and is then lowered into the collecting hopper 16. Subsequently, the ash is transferred to the limiting cylinder 18. This transfer of ash prevents it from accumulating inside the device and thus prevents it from hindering the combustion of the particles.

The pressurizing pump 25 is electrically connected to the intelligent control device 6. The output end of the pressurizing pump 25 is fixedly connected to a connecting pipe 26.

The connecting pipe 26 communicates with the flow divider ring 27, and the flow divider ring 27 communicates with the nozzle 28.

[0030] During operation, the pressurization pump 25 can transfer oxygen to the inside of the connecting pipe 26, then to the inside of the splitting ring 27, and then to the inside of the nozzle 28, so that oxygen can enter the inside of the particles. By whether or not oxygen is transferred, a control experiment can be formed, and the data of particle combustion can be detected.

[0031] The combustion chamber 1 is equipped with a detection component on its outer side. The detection component includes a water tank 32 fixedly connected to the outer side of the combustion chamber 1, a temperature sensor fixedly connected inside the water tank 32, an exhaust pipe 33 fixedly connected to the top of the combustion chamber 1, a sensor assembly 34 fixedly connected to the outer side of the exhaust pipe 33, and the interior of the exhaust pipe 33 is connected to the interior of the combustion chamber 1. Both the temperature sensor and the sensor assembly 34 are electrically connected to the intelligent control device 6.

[0032] During operation, the rate at which the water temperature inside the water tank 32 increases can be used to detect the heat dissipation of the particulate combustion. The sensor assembly 34 can also be used to detect the exhaust gas, thereby detecting the carbon dioxide content and PM2.5 levels inside the exhaust gas.

[0036] During operation, the motor 20 drives the first transmission rod 21 to rotate, which in turn drives the first bevel gear 22 to rotate, which in turn drives the second bevel gear 22 to rotate, which in turn drives the second transmission rod 23 to rotate, which in turn drives the gear 24 to rotate, which in turn drives the internal gear ring 11 to rotate, which in turn drives the first bearing plate 9, the second bearing plate 14, the third bearing plate 15 and the ventilated cone 13 to rotate, which in turn drives the particles to move, thus ensuring that oxygen can enter the burning particles. It also drives the first bearing plate 9 to rotate at the bottom of the sweeping plate 29, which in turn drives the particles to move, thus ensuring that oxygen can enter the particles more quickly, thus ensuring that the particles burn completely.

[0037] The working principle is as follows: the first bearing plate 9 is supported by the first limiting ring 8, and the inner toothed ring 11 is supported by the second limiting ring 12.
