Description

Technical Field

[0001] This utility model relates to the field of biomass fuel heating technology, and in particular to a heating boiler that uses biomass fuel. Background Technology

[0002] Biomass fuels refer to various organic substances formed through photosynthesis. They are a widely used energy source in daily life and industry. Heating through biomass fuels involves heating and burning them to generate heat energy, which is then used in heating equipment.

[0003] When traditional heating equipment relies on biomass fuel, the biomass fuel may become damp, leading to increased moisture content, incomplete combustion, excessive smoke, and ash covering the bottom of the fuel, resulting in waste and low heating efficiency. Utility Model Content

[0004] To overcome the shortcomings of traditional heating equipment, such as biomass fuel becoming damp and ash from combustion obscuring the bottom of the biomass fuel, resulting in incomplete combustion and low heating efficiency, this utility model provides a biomass fuel-based heating boiler that can keep the biomass fuel dry through combustion smoke and allow unburned biomass fuel to better contact with air, thus enabling more complete combustion and improving heating efficiency.

[0005] The technical solution of this utility model is as follows: a heating boiler using biomass fuel, comprising a heating furnace, an insulating door, a hopper, a sliding frame, an electric push rod, and a water tank. The heating furnace has a feed inlet at its top and a chimney fixedly connected to the top. Two insulating doors are slidably connected to the heating furnace. A hopper is fixedly connected to the top of the heating furnace, and a sliding frame is slidably connected to the hopper. The sliding frame has a through groove, and the feed inlet of the heating furnace communicates with the through groove of the sliding frame. An electric push rod is fixedly connected to the hopper, and the telescopic shaft of the electric push rod is fixedly connected to the side of the sliding frame. The heating furnace has a water tank fixedly connected inside, and an agitation mechanism is installed on the hopper. The heating furnace is equipped with a vibration mechanism. When the electric push rod is activated, it drives the agitation mechanism to agitate the biomass fuel in the hopper, so that the biomass fuel in the hopper can be heated and dried evenly, and the biomass fuel can be burned more completely. The electric push rod drives the vibration mechanism to vibrate the biomass fuel in the heating furnace, so that the ash after the biomass fuel is burned falls to the bottom of the heating furnace, and the unburned biomass fuel can have better contact with the air, further making the biomass fuel burn more completely.

[0006] In one embodiment, the agitation mechanism includes a rotating frame, a gear, a rack frame, and a heat-conducting frame. The rotating frame is rotatably connected to the silo, and a gear is fixedly connected to one end of the rotating frame. A rack frame is fixedly connected to the side of the sliding frame near the gear, and the rack frame meshes with the gear. A heat-conducting frame is fixedly connected to the chimney and the silo.

[0007] In one embodiment, the vibration mechanism includes a transmission frame, a partition plate, a transmission rod, a guide frame, and a slider. The transmission frame is fixedly connected to the telescopic shaft of the electric push rod. The partition plate is slidably connected inside the heating furnace. The transmission rod is fixedly connected to the partition plate. The guide frame is fixedly connected to the bottom of the transmission frame. The guide frame has a guide groove. The upper end of the transmission rod is slidably connected to the guide groove of the guide frame. A guide block is fixedly connected to the guide frame. A slider is slidably connected to the guide frame.

[0008] In one embodiment, a guide plate is also included, which is fixedly connected inside the heating furnace.

[0009] In one embodiment, the heat-conducting bracket is made of brass.

[0010] Beneficial effects: The effects of this utility model are: 1. The telescopic shaft of the electric push rod reciprocates at fixed intervals, driving the sliding frame to slide back and forth, continuously adding a certain amount of biomass fuel to the heating furnace, so that the heating furnace is always in a heating state, improving the heating efficiency.

[0011] 2. The heat-conducting frame transfers heat to the biomass fuel. When the biomass fuel is heated, the moisture in the biomass fuel evaporates, keeping the biomass fuel dry. The reciprocating sliding of the rack and pinion frame drives the rotating frame to oscillate back and forth. The oscillation of the rotating frame agitates the biomass fuel in the silo, ensuring that the biomass fuel in the silo is heated and dried evenly, and allowing the generated water vapor to be discharged, so that the biomass fuel can be burned more completely.

[0012] 3. The transmission rod will separate from the guide block, and the transmission rod and the partition plate will fall rapidly downwards under the action of gravity. The partition plate will vibrate, causing the ash from the biomass fuel combustion to fall to the bottom of the heating furnace, so that the biomass fuel added later can better contact the original ignition source. At the same time, the vibration will separate the unburned biomass fuel that has accumulated together, so that the unburned biomass fuel can better contact the air, and further make the biomass fuel more completely burned.

Detailed Implementation

[0020] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0021] Example 1: A heating boiler using biomass fuel, such as Figures 1-3 As shown, the system includes a heating furnace 1, an insulated door 2, a hopper 3, a sliding frame 4, an electric push rod 5, and a water tank 6. The heating furnace 1 has a feed inlet at its top and a chimney 31 welded to its top. Two insulated doors 2 are slidably connected to the heating furnace 1. The hopper 3 is bolted to the top of the heating furnace 1, and a sliding frame 4 is slidably connected to the hopper 3. The sliding frame 4 has a through-slot for holding biomass fuel. The feed inlet of the heating furnace 1 communicates with the through-slot of the sliding frame 4. An electric push rod 5 is bolted to the hopper 3, and the telescopic shaft of the electric push rod 5 engages with the side of the sliding frame 4. The interior of the heating furnace 1 is welded with a water tank 6, which is used to store water for heating. The hopper 3 is equipped with an agitation mechanism, and the heating furnace 1 is equipped with a vibration mechanism. The electric push rod 5 is activated to drive the agitation mechanism to agitate the biomass fuel in the hopper 3, so that the biomass fuel in the hopper 3 can be heated and dried evenly, and the biomass fuel can be burned more completely. The electric push rod 5 drives the vibration mechanism to vibrate the biomass fuel in the heating furnace 1, so that the ash after the biomass fuel is burned falls to the bottom of the heating furnace 1, and the unburned biomass fuel can have better contact with the air, further making the biomass fuel burn more completely.

[0022] Initially, the workers filled the hopper 3 with biomass fuel. Then, they pushed the lower insulating door 2 along the outer wall of the heater 1 to open it, added biomass fuel into the heater 1, and ignited it. Next, they pushed the lower insulating door 2 in the opposite direction to close it, igniting the biomass fuel in the heater 1 to heat the water in the water tank 6. The flue gas produced by the burning biomass fuel was discharged from the chimney 31 at the top of the heater 1. After the biomass fuel had been burning for a period of time, the workers activated the electric push rod 5. The extension of the telescopic shaft of the push rod 5 will push the sliding frame 4 to move. The movement of the sliding frame 4 will connect the through groove of the sliding frame 4 with the hopper 3. The biomass fuel in the hopper 3 will enter the through groove of the sliding frame 4. Subsequently, the retraction of the telescopic shaft of the electric push rod 5 will drive the sliding frame 4 to reset. The through groove of the sliding frame 4 will connect with the feed port of the heating furnace 1. The biomass fuel in the through groove of the sliding frame 4 will enter the heating furnace 1. The electric push rod 5 will reciprocate and extend at fixed intervals, driving the sliding frame 4 to slide back and forth, continuously adding a certain amount of biomass fuel to the heating furnace 1, so that the heating furnace 1 is always in a heating state, improving the heating efficiency.

[0023] Example 2: Based on Example 1, such as Figures 1-3 As shown, the agitation mechanism includes a rotating frame 7, a gear 8, a rack frame 9, and a heat-conducting frame 10. The rotating frame 7 is rotatably connected to the silo 3. One end of the rotating frame 7 is fixedly connected to the gear 8. The rack frame 9 is welded to the side of the sliding frame 4 near the gear 8. The rack frame 9 meshes with the gear 8. The heat-conducting frame 10 is welded to the chimney 31 and the silo 3. The heat-conducting frame 10 can transfer heat.

[0024] The flue gas discharged from the chimney 31 at the top of the heating furnace 1 heats the heat conduction frame 10, which then transfers heat to the silo 3. The biomass fuel near the heat conduction frame 10 is heated, and the heating process evaporates the moisture in the biomass fuel, keeping it dry and facilitating subsequent combustion. The reciprocating sliding of the sliding frame 4 drives the rack frame 9 to reciprocate, which in turn drives the gear 8 to rotate. The rotation of the gear 8 drives the rotating frame 7 to oscillate, which agitates the biomass fuel in the silo 3. This ensures that the biomass fuel in the silo 3 is heated and dried evenly, and that the generated water vapor is discharged, allowing for more complete combustion of the biomass fuel.

[0025] Example 3: Based on Example 2, such as Figures 3-6As shown, the vibration mechanism includes a transmission frame 11, a partition plate 12, a transmission rod 13, a guide frame 14, and a slider 16. The transmission frame 11 is bolted to the telescopic shaft of the electric push rod 5. The partition plate 12 is slidably connected inside the heating furnace 1. The transmission rod 13 is welded to the partition plate 12. The guide frame 14 is welded to the bottom of the transmission frame 11. The guide frame 14 has a guide groove. The upper end of the transmission rod 13 is slidably connected to the guide groove of the guide frame 14. A guide block 15 is fixedly connected to the guide frame 14. The slider 16 is slidably connected to the guide frame 14.

[0026] Initially, the operator pushes the upper insulating door 2 along the outer wall of the heating furnace 1 to open it, places biomass fuel on the partition plate 12, and ignites the biomass fuel. Then, the insulating door 2 is closed. Next, the extension shaft of the electric push rod 5 extends, causing the transmission frame 11 to move. The movement of the transmission frame 11 moves the guide frame 14, guide block 15, and slider 16. The slider 16 presses against the transmission rod 13, causing it to move upwards. The upward movement of the transmission rod 13 disengages from the slider 16 and contacts the guide block 15. The guide block 15 then presses against the transmission rod 13, causing it to move upwards. Moving rod 13 upward will cause partition plate 12 to move upward. As the transmission rod 13 continues to move upward, it will separate from guide block 15. The transmission rod 13 and partition plate 12 will fall rapidly downward under the action of gravity. When partition plate 12 falls rapidly downward, it will come into contact with heating furnace 1. Partition plate 12 will vibrate, causing the ash after the biomass fuel is burned to fall to the bottom of heating furnace 1. This allows the biomass fuel added later to come into better contact with the original ignition source. At the same time, the vibration will separate the unburned biomass fuel that has accumulated together, allowing the unburned biomass fuel to come into better contact with air, and further enabling the biomass fuel to be burned more completely.

[0027] Example 4: Based on Example 3, such as Figure 4 As shown, it also includes a guide plate 17, which is welded inside the heating furnace 1.

[0028] The through slot of the sliding frame 4 is connected to the feed port of the heating furnace 1. Biomass fuel in the through slot of the sliding frame 4 will enter the heating furnace 1. The biomass fuel will be guided by the guide plate 17 when it enters the heating furnace 1, so that the biomass fuel will no longer fall directly, but will be guided by the guide plate 17 to fall towards the middle position of the heating furnace 1, so that most of the biomass fuel falls to the middle position, and the burning flame heats the water tank 6 in the middle position of the heating furnace 1.

[0029] Example 5: Based on Example 4, such as Figures 3-4 As shown, the heat conduction bracket 10 is made of brass.

[0030] The brass heat conduction frame 10 can better guide heat from the flue gas into the hopper 3.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
