Description

Technical Field

[0001] This utility model relates to the field of biomass stove technology, specifically to a feeding and slag removal device for biomass stoves. Background Technology

[0002] Biomass stoves are multifunctional and environmentally friendly devices that use biomass fuels (straw, wood chips, etc.) and coal as energy sources. When using biomass stoves, fuel needs to be fed through a feeding and slag removal device, such as the double auger feeding and slag removal device for biomass stoves disclosed in patent number CN206112903U.

[0003] When using this patent, it is inconvenient to crush the biomass briquettes during feeding, resulting in a large volume of biomass briquettes. This not only easily leads to blockages but may also result in incomplete gasification, leading to reduced combustion efficiency. Utility Model Content

[0030] 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.

[0031] Example 1

[0032] A preferred embodiment of the feeding and slag removal equipment for biomass stoves provided by this utility model is, for example... Figures 1 to 3The image shows a feeding and slag removal device for a biomass stove, comprising a charcoal basin 1, a connecting plate 2 connected to one side of the charcoal basin 1, a lower auger cylinder 4 connected to the side of the connecting plate 2 away from the charcoal basin 1, a connecting pipe 5 connected to the top of the lower auger cylinder 4, an upper auger cylinder 6 connected to the top of the connecting pipe 5, and a feed hopper 7 connected to the top of the upper auger cylinder 6. A support plate 8 is connected to the end of the lower auger cylinder 4 away from the connecting plate 2 via a flange. A drive motor 9 is connected to the surface of the support plate 8. The output shaft of the drive motor 9 is connected to a drive shaft 10 connected to the auger inside the lower auger cylinder 4. A first drive sprocket 11 is connected to the surface of the drive shaft 10. A first driven sprocket 12 is connected to the first driven sprocket 11 via a chain. A first output shaft 13 connected to the auger inside the upper auger cylinder 6 is connected to the inner wall of the first driven sprocket 12.

[0033] Regarding how to ignite, this embodiment further explains that an ignition rod 3 is connected to the inner wall of the connecting plate 2. One end of the ignition rod 3 passes through the connecting plate 2 and extends into the interior of the charcoal basin 1, thereby facilitating the ignition of the fuel through the ignition rod 3.

[0034] Regarding how the air is delivered, this embodiment further explains that a blower 21 is connected to the bottom of the support plate 8, and the air supply pipe of the blower 21 passes through the connecting plate 2 and is connected to the charcoal basin 1, thereby facilitating the delivery of air into the fuel.

[0035] Among them, the blower 21 has an air supply pipe 22 connected to its air supply pipe surface, and the air outlet of the air supply pipe 22 is connected to the upper auger tube 6, which facilitates the delivery of air into the interior of the upper auger tube 6.

[0036] Based on the above embodiments, the present invention further describes that a second drive sprocket 14 is connected to the surface of the first output shaft 13, a second driven sprocket 15 is connected to the second drive sprocket 14 via a chain, a second output shaft 16 is connected to the inner wall of the second driven sprocket 15, a drive gear 17 is connected to the surface of the second output shaft 16, a driven gear 18 is connected to one side of the drive gear 17, a third output shaft 19 is connected to the inner wall of the driven gear 18, and a crushing roller 20 is connected to the surfaces of the second output shaft 16 and the third output shaft 19 that extend into the feed hopper 7.

[0037] Specifically, the chains on the second driving sprocket 14 and the second driven sprocket 15 are arranged at an angle, and the second output shaft 16 and the third output shaft 19 are symmetrically distributed on both sides of the feed bin 7. The second output shaft 16 is connected to the feed bin 7 through a bearing and rotates through it, and the third output shaft 19 is connected to the feed bin 7 through a bearing and rotates through it. This facilitates the simultaneous rotation of the two first output shafts 13 and the second output shaft 16 in opposite directions, which in turn facilitates the crushing of biomass briquettes by the two crushing rollers 20 after they rotate in opposite directions.

[0038] In operation, the biomass briquettes are first placed into the feed hopper 7. Then, the drive motor 9 is started, causing the drive motor 9 to rotate the drive shaft 10. The drive shaft 10 then rotates the auger inside the lower auger cylinder 4 to feed the material. Simultaneously, the drive shaft 10 rotates the first drive sprocket 11, which in turn rotates the first driven sprocket 12 via a chain. The driven sprocket 12 then rotates the auger inside the upper auger cylinder 6 via the first output shaft 13 to feed the material. At the same time, the first output shaft 13 rotates the second drive sprocket 14. The rotation causes the second drive sprocket 14 to drive the two driven sprockets 15 to rotate via a chain. The second driven sprockets 15 then drive the second output shaft 16 to rotate. The second output shaft 16, through the drive gear 17 and the driven gear 18, drives the third output shaft 19 to rotate in the opposite direction. This causes the second output shaft 16 and the third output shaft 19 to drive the two crushing rollers 20 to rotate in the opposite direction, thus crushing the biomass briquettes. This helps to ensure that the biomass briquettes are fully gasified, mixed with air, and improve combustion efficiency. It also effectively prevents the biomass briquettes from accumulating and clogging.
