Description

Technical Field

[0001] This invention belongs to the field of straw biomass fuel preparation technology, and particularly relates to a straw biomass pellet fuel preparation device. Background Technology

[0002] Straw biomass pellet fuel is an environmentally friendly fuel made from crop straw as the main raw material through processes such as crushing, mixing, and hot-melting molding. It has advantages such as stable calorific value, cleanliness and no pollution, and renewability, and is widely used in industrial boilers, residential heating and other fields.

[0003] Currently, the preparation of straw biomass pellet fuel often requires the thermal melting and mixing of straw powder with various materials such as binders and combustion improvers. Workers typically use a manual, batch-feeding method: first adding straw powder, then adding binders and other auxiliary materials, and finally starting the thermal melting device to mix and melt the materials. This batch-feeding method easily leads to uneven mixing of materials and poor integration between straw powder and auxiliary materials, affecting the subsequent pellet fuel forming quality and combustion performance. Therefore, there is an urgent need for straw biomass pellet fuel preparation equipment that can achieve thorough mixing of materials. Summary of the Invention
