Technical Field

[0001] The invention relates to the field of energy technology, in particular to a biomass fuel boiler with a feeding function. Background Art

[0002] Biomass fuel, as a renewable energy source, comes from plants and animals, including wood residues, agricultural waste, energy crops and urban solid waste, etc., and has a wide range of sources and renewability. Biomass boilers use this organic matter for combustion, and the energy generated is used in many fields such as heating, hot water supply, industrial steam, etc., which has significant environmental protection and sustainable development advantages. In order to improve combustion efficiency and energy utilization, biomass boilers need to consider many factors during design and operation, such as the water content of the fuel, particle size, temperature distribution in the combustion chamber, and air input rate. In terms of technology, biomass boilers have undergone continuous innovation and improvement. For example, some boilers use a two-stage heating structure, and the application field of biomass boilers has been continuously expanded, covering many aspects such as industry, agriculture, and residents' lives. In the industrial field, biomass boilers can provide heat sources for enterprises and reduce energy consumption costs; in the agricultural field, biomass boilers can be used to dry crops and provide greenhouse heat sources; in the field of residents' lives, biomass boilers can provide hot water and heating for families.

[0047] When the second rotating rod 701 rotates, the rotation of the second rotating rod 701 drives the cam 801 to rotate, and the cam 801 periodically hits the sieve plate 202 to make the sieve plate 202 vibrate. The vibration of the sieve plate 202 prevents the sieve plate 202 from being blocked by residues.

[0048] The plurality of air inlet holes 901 are provided on the side of the combustion furnace 201 close to the second gear 703 , and are provided below the second rotating rod 701 , and are communicated with the interior of the combustion furnace 201 .

[0050] Working principle: At the beginning of work, the staff adds fuel from the feed hopper 510 into the storage box 508, and then the staff turns on the second motor 601, the fan 209, the dual-axis motor 206, the igniter 203 and the air purifier 401 through the controller 102. The second motor 601 rotates to drive the cutting blade 602 to rotate, and the cutting blade 602 rotates to cut and crush the fuel in the storage box 508, thereby improving the combustion efficiency of the fuel.

[0051] When the fan 209 is working, the fan 209 delivers air to the interior of the combustion furnace 201 through the air inlet pipe 210 to provide oxygen for the combustion of the fuel.

[0052] When the dual-axis motor 206 is working, the two rotating shafts of the dual-axis motor 206 rotate to respectively drive the connecting rod 207 and the active bevel gear 504 to rotate. The rotation of the connecting rod 207 drives the screw-belt blade 208, the circular baffle 304 and the first gear 702 to rotate. The screw-belt blade 208 rotates to stir the fuel in the combustion furnace 201, so that the fuel burns more completely.

[0053] When the circular baffle 304 rotates, the circular baffle 304 drives the arc-shaped opening 305 to rotate. When the arc-shaped opening 305 is connected to the feed port 303, the fuel in the preheating box 301 enters the combustion chamber for combustion. When the arc-shaped opening 305 is not connected to the feed port 303, the fuel is preheated in the preheating box 301 to remove moisture from the fuel and improve the combustion efficiency of the fuel.

[0054] When the first gear 702 rotates, the rotation of the first gear 702 drives the second gear 703 to rotate, the rotation of the second gear 703 drives the second rotating rod 701 to rotate, the rotation of the second rotating rod 701 drives the spiral blade 705 and the cam 801 to rotate, the rotation of the spiral blade 705 pushes the residue that falls on the arc plate 704 into the collection box 706 through the connection between the combustion furnace 201 and the collection box 706, so as to facilitate the staff to recycle it.

[0055] When the cam 801 rotates, the cam 801 periodically hits the sieve plate 202, causing the sieve plate 202 to vibrate. The vibration of the sieve plate 202 prevents the sieve plate 202 from being blocked by residues.

[0056] When the active bevel gear 504 rotates, the active bevel gear 504 drives the passive bevel gear 505 to rotate, the passive bevel gear 505 drives the first rotating rod 503 to rotate, the first rotating rod 503 drives the turntable 506 to rotate, the turntable 506 drives the crankshaft 507 to rotate, the crankshaft 507 drives the piston 502 to move left and right, when the arc opening 305 is connected with the feed port 303, when the piston 502 moves to the right, it pushes the fuel in the conveying cylinder 501 into the preheating chamber for preheating and drying to improve the combustion efficiency, and at the same time, the piston 502 will cover the opening of the connecting pipe 509 to prevent the fuel from falling into the conveying cylinder 501.

[0057] When the arc-shaped opening 305 is not connected to the feed port 303 , the piston 502 moves to the left. When the piston 502 moves to the left and no longer blocks the connecting pipe 509 , the fuel in the storage box 508 enters the delivery cylinder 501 through the connecting pipe 509 .

[0058] When the air purifier 401 is working, the air purifier 401 filters the harmful gases produced by combustion and then discharges them into the air, thereby achieving the effect of protecting the environment.

[0059] When the fuel enters the combustion furnace 201, the controller 102 turns on the igniter 203 to ignite the fuel.
