Description

Technical Field

[0001] The invention relates to the technical field of biomass steam boilers, and in particular to a fully automatic biomass steam boiler. Background Art

[0002] Biomass steam boiler is a kind of biomass boiler. It is a steam boiler that burns biomass fuel as raw material. Biomass steam boiler uses straw, rice straw, firewood, wood chips, peanut shells, melon seed shells, beet pulp, bark and other crop waste as fuel for combustion, which effectively reduces energy consumption, reduces carbon dioxide, sulfur dioxide and nitrogen oxide emissions, and improves the environment.

[0003] In a fully automatic biomass steam boiler, fuel is usually transported to the combustion chamber or furnace body through a conveying device. However, when the fuel falls into the furnace body from the end of the spiral roller, due to factors such as fuel shape and particle size, the fuel may accumulate in the furnace body, which will lead to uneven fuel distribution, incomplete fuel combustion, and low fuel combustion efficiency. Therefore, a fully automatic biomass steam boiler is proposed. Summary of the invention

[0115] The gas outlet pipe 27 is disposed at the lower part of the cylinder body 21 , one end of the cylinder body 21 is communicated with the cylinder body 21 , and the other end of the cylinder body 21 passes through the side of the furnace body 2 and the partition plate 4 , and is communicated with the gas injection pipe 25 .

[0116] When the oxygen content in the furnace body 2 needs to be increased, the slider 12 drives the plug rod 23 to move downward, the plug rod 23 stretches the second spring 24, drives the piston 22 to move downward, and the piston 22 pushes the air in the cylinder body 21 into the injection pipe 25 through the outlet pipe 27, and then is ejected from the inner circle of the injection pipe 25, thereby increasing the oxygen content in the furnace body 2 and thus improving the combustion efficiency of the biomass fuel.

[0117] When the second spring 24 moves upward and resets, the second spring 24 drives the piston 22 to move upward, and the piston 22 drives the external gas to enter the cylinder 21 through the air inlet pipe 26, so as to continue to introduce air into the furnace body 2.

[0118] Both the air inlet pipe 26 and the air outlet pipe 27 are provided with one-way valves.

[0119] Prevent gas backflow.

[0120] The inner circle of the air injection pipe 25 is evenly distributed with a plurality of air injection ports.

[0121] This allows the air to be sprayed evenly onto the fuel.

[0122] Working principle: When using this equipment, the staff opens the valve 7 through the controller 28, and then the staff pours the biomass fuel into the feed hopper 6. The fuel falls into the conveying tube 5 through the feed hopper 6. The staff starts the drive motor 8 through the controller 28. The rotating shaft of the drive motor 8 drives the protrusion 13 to rotate, drives the spiral roller 9 to rotate, and the spiral roller 9 pushes the fuel, pushing the fuel into the furnace body 2. The smoke generated after the fuel is burned is discharged through the exhaust pipe 3, and the heat generated is transferred to the water in the boiler, causing the water to evaporate into steam. Then the staff starts the fan 29 through the controller 28. The fan 29 extracts the high-temperature smoke discharged from the exhaust pipe 3. The high-temperature smoke enters the filter box 30 through the pipeline, and after being filtered by the filter box 30, it enters the air pipe of the conveying tube 5 through the first connecting pipe 31, and then sprays to the fuel, thereby drying the fuel.

[0123] When the rotating shaft of the driving motor 8 drives the protrusion 13 to rotate, the protrusion 13 intermittently pushes the protrusion rod 14 to move downward.

[0124] When the protrusion 13 pushes the protruding rod 14 to move downward, the protruding rod 14 stretches the first spring 15, driving the slider 12 to move downward, the slider 12 drives the plug rod 23 to move downward, drives the movable rod 16 to move downward, the movable rod 16 drives the first gear 20 to move downward, drives the bulk plate 17 to move downward, so that the bulk plate 17 can scatter the falling fuel at different heights, so that the fuel falls evenly above the partition 4.

[0125] When the movable rod 16 drives the first gear 20 to move downward, the first gear 20 meshes with the plurality of racks 19 in sequence, and then the first gear 20 rotates back and forth, and the first gear 20 drives the movable rod 16 to rotate back and forth, and the movable rod 16 drives the bulk plate 17 to swing. The swing of the bulk plate 17 allows the fuel to be further evenly scattered onto the partition 4, and when the fuel is scattered by the bulk plate 17, it will be subjected to impact force, thereby breaking up the agglomerated fuel to prevent incomplete combustion of the agglomerated fuel.

[0126] When the slider 12 drives the plug rod 23 to move downward, the plug rod 23 stretches the second spring 24, driving the piston 22 to move downward, and the piston 22 pushes the air in the cylinder 21 to pass through the one-way valve and the air outlet pipe 27 in sequence, enter the injection pipe 25, and then be ejected from the multiple injection ports on the inner circle of the injection pipe 25, thereby increasing the oxygen content in the furnace body 2 and thus improving the combustion efficiency of the biomass fuel.

[0127] When the protrusion 13 moves away from the protruding rod 14, the first spring 15 and the second spring 24 move up and reset, the first spring 15 drives the slider 12 to move up, the slider 12 drives the movable rod 16 to move up, the movable rod 16 drives the first gear 20 to move up, and drives the bulk plate 17 to move up, so that the bulk plate 17 can scatter the falling fuel at different heights, so that the fuel falls evenly above the partition 4.

[0128] When the movable rod 16 drives the first gear 20 to move upward, the first gear 20 repeatedly meshes with the plurality of racks 19 in sequence, and then the first gear 20 rotates back and forth, and the first gear 20 drives the movable rod 16 to rotate back and forth, and the movable rod 16 drives the bulk plate 17 to swing. The swing of the bulk plate 17 allows the fuel to be further evenly scattered onto the partition 4, and when the fuel is scattered by the bulk plate 17, it will receive an impact force, thereby breaking up the agglomerated fuel to prevent incomplete combustion of the agglomerated fuel.

[0129] When the second spring 24 moves upward and resets, the second spring 24 drives the piston 22 to move upward, and the piston 22 drives the external gas to pass through the air inlet pipe 26 and the one-way valve in sequence and enter the cylinder body 21, so as to continue to introduce air into the furnace body 2 later.

[0130] The above embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall all fall within the scope of protection of the present invention.
