[0028] Working principle:

[0029] When using an automatic crusher to process raw materials for biomass combustion:

[0030] Preparation process:

[0031] First, pull the pull rod 802 to slide along the slide groove processed on the first shell 801, thereby driving the cross bar 803 to move to the right. The movement of the cross bar 803 to the right drives the limit plate 804 to move to the right along the inner wall of the sleeve 805, compressing the spring 806. Then the operator inserts the filter screen 14 along the slide groove processed on the first box body 9. Then the operator slowly loosens the pull rod 802 and uses the elasticity of the spring 806 to gradually move the cross bar 803 to the left. When the end of the cross bar 803 is tightly pressed against the normal inner wall processed on the filter screen 14, the filter screen 14 can be fixed to filter the incompletely crushed biomass combustion raw materials. The power supply of the two first motors 12 is started, and the output shafts of the two first motors 12 rotate relative to each other, driving the two crushing rollers 11 to rotate relative to each other.

[0032] Used in the crushing and filtering process of biomass combustion raw materials:

[0033] The raw materials for biomass combustion are added into the first box body 9 from the feed port 10, and are crushed by two crushing rollers 11. Qualified raw materials for biomass combustion pass through the filter 14 and enter the end of the first box body 9, and unqualified raw materials for biomass combustion can be discharged from the first discharge port 13, and can be collected by the operator for secondary crushing.

[0034] Used in the mixing process of biomass combustion raw materials:

[0035] After the qualified raw materials for biomass combustion enter the bottom of the first box body 9, the external power supply of the oil pump is started to draw the environmentally friendly solvent oil into the oil inlet pipe 16 and spray it out from the nozzle installed on the surface of the oil inlet pipe 16. At the same time, the power supply of the third motor 702 is started, and the output shaft of the third motor 702 rotates to drive the first gear 703 to rotate, thereby driving the two second gears 704 to rotate, and then the three rotating rods 705 can be driven to rotate. The rotation of the three rotating rods 705 drives multiple stirring blades 6 to rotate, and the stirring blades 6 drive the qualified raw materials for biomass combustion to be continuously turned over, so that the qualified raw materials for biomass combustion are fully mixed with the environmentally friendly solvent oil, so as to achieve that some qualified raw materials for biomass combustion are not mixed with the environmentally friendly solvent oil and are directly discharged.

[0036] Used in the process of discharging raw materials for biomass combustion:

[0037] Open the valve processed on the connecting pipe 5, discharge the stirred qualified raw materials for biomass combustion from the connecting pipe 5 and enter the second box body 2, start the power supply of the second motor 4, and the output shaft of the second motor 4 rotates to drive the spiral blade to rotate, driving the stirred qualified raw materials for biomass combustion to move to the left, so that the second discharge port 17 on the left is squeezed out. The environmentally friendly solvent oil has good flammability and volatility, which can make the successfully shaped crushed materials quickly set in shape. Subsequently, the successfully shaped crushed materials will break due to their own gravity after drying, and the segmented biofuel is more convenient to store and transport.

[0038] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
