Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sawdust biomass pellet processing, in particular to a sawdust biomass pellet processing feeding device and a processing method thereof. BACKGROUND

[0002] Sawdust pellets, also known as biomass fuel pellets, are mainly processed from pine, fir, birch, poplar, fruit wood and crop stalks, and are used for burning, barbecuing and fireplace heating. The burning efficiency is more than 80%, the production of sulfur dioxide, ammonia nitrogen compounds and dust is less, and the burning efficiency is high.

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

[0004] When the sawdust is conveyed to the pellet granulator by the feeding device for granulation, the main wear parts of the feeding device are the spiral blades and the machine groove body. At the same time, when conveying, the impact force and friction force of the sawdust just entering the conveyor are large, which usually causes more serious wear at the feeding end. After the sawdust is conveyed, the impact force and friction force are small, which causes relatively light wear at the discharging end. At the same time, uneven distribution of sawdust causes different forces at both ends of the blade. The feeding end is more seriously worn due to the concentration of materials. The discharging end has less material and is less worn. Thus, the wear difference between the feeding and discharging ends of the spiral blade is large. At the same time, the replacement of the integral spiral blade is difficult and the replacement cost is high. SUMMARY
