Description

Technical Field

[0001] The invention relates to the technical field of sawdust biomass particle processing, and in particular to a sawdust biomass particle processing and feeding device and a processing method thereof. Background Art

[0002] Wood chip pellets, also known as biomass fuel pellets, are mainly made from pine, fir, birch, poplar, fruit wood and crop stalks. They are used for combustion, barbecue and fireplace heating. The combustion efficiency is more than 80%, and the production of sulfur dioxide, ammonia nitrogen compounds and dust is low.

[0003] The processing steps of wood chip biomass pellets mainly include the following links: raw material preparation, wood chip collection, screening and impurity removal, drying and crushing, humidity adjustment, and compression and pelletizing.

[0004] When the sawdust is conveyed to the pelletizing machine through the feeding device for pelletizing, the main wear parts of the feeding device are the spiral blades and the machine trough body. At the same time, when conveying, the sawdust has just entered the conveyor, the impact force and friction are large, resulting in more serious wear at the feed end. After the sawdust is conveyed, the impact force and friction are small, resulting in relatively light wear at the discharge end. At the same time, the uneven distribution of sawdust causes different forces at both ends of the blade. The feed end is more severely worn due to the concentration of materials; the discharge end has less material and lighter wear, which leads to a large difference in wear between the feed and discharge ends of the spiral blade. At the same time, the integral spiral blade is difficult to replace and the replacement cost is high. Summary of the invention
