Description

Technical Field

[0001] This utility model relates to the field of biomass pellet technology, specifically to an energy-saving biomass pellet combustion furnace. Background Technology

[0002] A biomass pellet combustion furnace is a combustion device that uses biomass pellets (compressed from agricultural and forestry waste such as sawdust, straw, and rice husks) as fuel. It generates heat energy through gasification pyrolysis and high-temperature combustion, and is widely used in heating, industrial heating, and agricultural drying. Biomass pellet fuel is renewable, and its carbon emissions are nearly 70% lower than traditional coal combustion, meeting environmental standards. Biomass pellets have a high density (1.1-1.4 g / cm³). 3 It has a stable calorific value (16-19 MJ / kg) and a moisture content of less than 12%.

[0003] When using biomass pellet combustion furnaces, the biomass pellets contain moisture. Excessive moisture content can lead to incomplete combustion, resulting in waste of biomass pellets. Existing biomass pellet combustion furnaces lack effective means to dry the biomass pellets before combustion. Furthermore, during combustion, the biomass pellets tend to accumulate in large quantities, and the insufficient contact area between the pellets and oxygen further contributes to incomplete combustion. After the operation is complete, a large number of unburned biomass pellets remain inside the furnace, affecting combustion efficiency and causing significant waste. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0017] Example: Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 An energy-saving biomass pellet combustion furnace includes a reaction chamber 1, a feed hopper 2 fixedly connected to the top of the reaction chamber 1, a roller 3 fixedly connected to the bottom of the feed hopper 2, a combustion groove 11 opened inside the reaction chamber 1, and a reciprocating assembly inside the reaction chamber 1. The reciprocating assembly includes a second motor 15, which is fixedly connected inside the reaction chamber 1. One end of the drive shaft of the second motor 15 is fixedly connected to a turntable 18, and the end of the turntable 18 away from the second motor 15 is fixedly connected to a fixed column 19. A movable plate 20 is movably sleeved on the outer circular wall of the fixed column 19, and a support block 22 is fixedly connected to the end of the movable plate 20 away from the fixed column 19. The interior of the reaction chamber 1 is fixedly connected to... There is a first positioning block 16, and a sliding groove 17 is opened on the top of the first positioning block 16. The interior of the sliding groove 17 is slidably connected to the support block 22. The top of the support block 22 is fixedly connected to the support plate 12. A heating component is installed inside the reaction chamber 1. A ventilation port 13 is opened inside the combustion tank 11. A first filter plate 9 and a second filter plate 10 are fixedly connected inside the reaction chamber 1. An air outlet 28 is fixedly connected to the outside of the reaction chamber 1. Moving grooves 14 are opened on both sides inside the combustion tank 11. Both moving grooves 14 are slidably connected to the support plate 12. Two return springs 21 are fixedly connected inside the two sliding grooves 17. The two return springs 21 are fixedly connected to the support block 22. When the biomass pellets are burning, the second motor 15 is activated by the control box outside the reaction chamber 1. The second motor 15 drives the shaft to rotate clockwise, causing the turntable 18 to rotate clockwise. This causes the fixed column 19 to rotate clockwise, and then the moving plate 20 rotates around the fixed column 19. This causes the support block 22 to move closer to the turntable 18. Then, the two return springs 21 are compressed and stretched respectively, and the support plate 12 begins to move away from the vent 13 inside the two moving slots 14. When the fixed column 19 rotates to the farthest point with the turntable 18, it continues to rotate, and the support block 22 moves away from the turntable 18. Then, the two return springs 21 are stretched and compressed respectively, and the support plate 12 begins to move closer to the vent 13 inside the two moving slots 14. Through the reciprocating motion of the support plate 12, the biomass pellets piled on the surface of the support plate 12 can be evenly dispersed, so that the biomass pellets can burn more completely and improve the combustion efficiency of the biomass pellets. After the biomass pellets are burned, hot air enters the guide channel through the ventilation opening 13. Then, the hot air passes through the first filter plate 9 and the second filter plate 10 respectively, and then enters other reaction equipment through the air outlet 28. Through the filtration effect of the first filter plate 9 and the second filter plate 10, other impurities contained in the hot air are reduced, avoiding contamination and damage to other equipment.

[0018] refer to Figure 2 and Figure 5 The heating assembly includes a first motor 4, which is fixedly connected to the outside of the reaction chamber 1. One end of the drive shaft of the first motor 4 is fixedly connected to an auger 5. The end of the auger 5 away from the first motor 4 is fixedly connected to a cross rotating block 8. The cross rotating block 8 is movably sleeved with the reaction chamber 1. A filter roller 7 is fixedly connected to the outside of the cross rotating block 8. A hot air blower 6 is fixedly connected to the outer circular wall of the roller 3. Before burning the biomass pellets, the biomass pellets are fed into the roller 3 through the feed hopper 2. At the same time, the first motor 4 and the hot air blower 6 are started by the control box outside the reaction chamber 1. The drive shaft of the first motor 4 rotates clockwise, which drives the auger 5 to rotate clockwise. Then the cross block 8 starts to rotate clockwise, and then the filter drum 7 starts to rotate clockwise. At this time, the hot air blower 6 continuously blows hot air into the roller 3 and the filter drum 7. The hot air evaporates the moisture in the biomass pellets, reducing the moisture content of the biomass pellets and preventing incomplete combustion.

[0019] refer to Figure 1 and Figure 6 The reaction chamber 1 has two positioning slots 23 on its outside. The second positioning block 24 is movably sleeved inside the positioning slot 23. The second positioning block 24 is fixedly connected to the outside of the partition plate 25. The partition plate 25 has a threaded groove 26 on the side away from the reaction chamber 1. The inner circular wall of the threaded groove 26 is threaded with a screw 27. All the above structures are in two quantities, and are identical except for their size. By using the screw 27, when it is necessary to clean the combustion tank 11 or the first filter plate 9 and the second filter plate 10, first rotate the screw 27 counterclockwise. The screw 27 moves away from the reaction chamber 1 along the threaded groove 26. After the screw 27 leaves the reaction chamber 1, pull the screw 27 clockwise, and then the partition 25 starts to rotate clockwise. Subsequently, the second positioning block 24 starts to rotate clockwise. At this time, the partition 25 is opened, which makes it convenient for the staff to clean the combustion tank 11 or the first filter plate 9 and the second filter plate 10. This avoids excessive accumulation of biomass particle impurities after combustion in the combustion tank 11, which would reduce the combustion efficiency in the combustion tank 11. It also avoids clogging of the filter holes of the first filter plate 9 and the second filter plate 10, which would reduce the wind speed of the hot air blown out of the air outlet 28 and affect the production efficiency of other reaction equipment.

[0020] Please refer to the working principle. Figures 1-6 As shown, when the biomass pellets are burning, the second motor 15 is started by the control box outside the reaction chamber 1. The second motor 15 drives the shaft to rotate clockwise, causing the turntable 18 to rotate clockwise. Then the fixed column 19 starts to rotate clockwise, and then the moving plate 20 rotates around the fixed column 19. Then the support block 22 moves towards the turntable 18. Then the two return springs 21 are compressed and stretched respectively, and then the support plate 12 starts to move away from the vent 13 inside the two moving slots 14. When the fixed column 19 rotates to the farthest point with the turntable 18, it continues to rotate, and then the support block 22 moves away from the turntable 18. Then the two return springs 21 are stretched and compressed respectively, and then the support plate 12 starts to move towards the vent 13 inside the two moving slots 14. Through the reciprocating motion of the support plate 12, the biomass pellets piled on the surface of the support plate 12 can be evenly dispersed, so that the biomass pellets can burn more completely and improve the combustion efficiency of the biomass pellets.

[0021] After the biomass pellets are burned, hot air enters the guide channel through the ventilation opening 13. Then, the hot air passes through the first filter plate 9 and the second filter plate 10 respectively, and then enters other reaction equipment through the air outlet 28. Through the filtration effect of the first filter plate 9 and the second filter plate 10, other impurities contained in the hot air are reduced, avoiding contamination and damage to other equipment.

[0022] Before burning the biomass pellets, the biomass pellets are fed into the roller 3 through the feed hopper 2. At the same time, the first motor 4 and the hot air blower 6 are started by the control box outside the reaction chamber 1. The drive shaft of the first motor 4 rotates clockwise, which drives the auger 5 to rotate clockwise. Then the cross block 8 starts to rotate clockwise, and then the filter drum 7 starts to rotate clockwise. At this time, the hot air blower 6 continuously blows hot air into the roller 3 and the filter drum 7. The hot air evaporates the moisture in the biomass pellets, reducing the moisture content of the biomass pellets and preventing incomplete combustion.

[0023] By using the screw 27, when it is necessary to clean the combustion tank 11 or the first filter plate 9 and the second filter plate 10, first rotate the screw 27 counterclockwise. The screw 27 moves away from the reaction chamber 1 along the threaded groove 26. After the screw 27 leaves the reaction chamber 1, pull the screw 27 clockwise, and then the partition 25 starts to rotate clockwise. Subsequently, the second positioning block 24 starts to rotate clockwise. At this time, the partition 25 is opened, which makes it convenient for the staff to clean the combustion tank 11 or the first filter plate 9 and the second filter plate 10. This avoids excessive accumulation of biomass particle impurities after combustion in the combustion tank 11, which would reduce the combustion efficiency in the combustion tank 11. It also avoids clogging of the filter holes of the first filter plate 9 and the second filter plate 10, which would reduce the wind speed of the hot air blown out of the air outlet 28 and affect the production efficiency of other reaction equipment.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
