Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of feeding devices, in particular to a feeding device for biomass wood chip particles. Background Art
[0002] Wood chip pellets, also known as biomass combustion pellets, are mainly made from pine, fir, fruit wood and agricultural straw. They are made into wood chip pellets through processes such as crushing, drying, screening, granulation, cooling and packaging. They are usually used for combustion for heating. Their advantages lie in their high combustion efficiency and low dust production.
[0003] Most of the existing wood chip pellet feeding devices are integrated pelletizing devices, which cannot be disassembled for cleaning.

Raw materials of different sizes mixed with impurities such as pebbles are directly fed into the pelletizing bin through the feed port, which not only has low pelletizing efficiency but also causes machine strain. In addition, since the rotation range of the pressure roller cannot completely cover the mold plate, some wood chips will accumulate in the center of the mold plate and the inner wall of the pelletizing bin, making it difficult to clean in time.
