Description

TECHNICAL FIELD

[0001] The utility model relates to the field of biomass pellet combustion furnace accessories, especially to a novel double-ribbon-conveyor double-motor high-efficiency internal combustion engine. BACKGROUND

[0002] Biomass pellets are formed by cold-state densification of biomass straw, forestry waste and other raw materials under normal temperature conditions using a compression roller and a ring mold. A combustion basket is used for burning pellets in a furnace during combustion. The existing combustion basket uses a double-ribbon-conveyor double-motor feeding system to avoid backfire and ignite the material bin below.

[0003] According to the search, the Chinese patent publication No. CN219102967U discloses a double-ribbon-conveyor coke pushing combustion system, which includes a double-ribbon-conveyor pellet conveying device for pellet conveying. This system can effectively avoid the spread of fire along the feeding pipeline, which may cause backfire. A preheating space is formed between the preheating part and the flame guide plate, which can fully heat the pellets entering the combustion part, increase the temperature of the pellets, and reduce the difficulty of ignition, thereby effectively reducing the ignition time and improving the combustion efficiency.

[0004] However, the above-mentioned double-ribbon-conveyor double-motor high-efficiency internal combustion engine has the following problems in actual use. After the fuel is fully burned in the combustion chamber and the residue is formed, it will fall through the through hole on the combustion part to the base, and then slide out along the inclined surface of the base plate to complete the cleaning. However, the residue formed by combustion is not generated in large quantities at one time, and the slow falling of the residue will cause the accumulation of light residue on the base. This not only causes blockage of the space below the combustion chamber, but also requires manual cleaning by the user, increasing the operation difficulty. Therefore, a novel double-ribbon-conveyor double-motor high-efficiency internal combustion engine is proposed to solve the above-mentioned problems. UTILITY MODEL CONTENTS
