s1, extrusion shaping:

(1) placing undried biochar into the base 13, placing the biochar at a lower height than the top of the base 13, placing the base 13 on the bottom plate 4, and mixing the biochar and the bio-oil together to form a muddy shape;

(2) the cylinder 5 drives the base plate 4 and drives the base 13 to rise so that the base 13 is inserted into the collar 12 and sleeved into the sleeve rod 11.

Specifically, when the base 13 is just inserted into the collar 12, the spring 14 abuts against the chassis 151, the chassis 151 is located at the lower end limit position (the bottom surface of the chassis 151 is located at the upper end of the convex ring two 122), the lower end of the chassis 151 abuts against the upper ends of the seat ring 132 and the convex ring two 133, along with the gradual insertion of the base 13 into the collar 12, the outer wall of the seat ring 132 is engaged with the inner wall of the convex ring two 122 and slides relatively, and the upper ends of the seat ring 132 and the convex ring two 133 push the chassis 151 upward, so that the spring 14 is compressed.

When the base 13 is inserted into the lantern ring 12, the long rod 112 is inserted into the base 13 until reaching the bottom of the base 13, and the biochar in the base 13 is mud-shaped, so that the biochar can be squeezed out when the long rod 112 is inserted. The first lug boss 11211 is attached to the corresponding second lug boss 133, and the inner wall of the first lug boss 1331 is attached to the outer wall of the long rod 112. As shown in fig. 4, the radial side surface of the boss one 11211 is attached to the side surface of the boss one 1331, the circumferential side surface of the boss one 11211 is attached to the inner side wall of the boss two 1332, and the long rod 112 is inserted into the base 13, so that the biochar in the base 13 is extruded, and the residual bio-oil on the biochar flows out along the through hole 1311 after being extruded due to the through hole 1311 arranged at the bottom of the base 13. During extrusion, the baffle ring sleeve 15 is matched with the outer wall of the long rod 112 and the upper end disc of the convex ring one 1121 to seal the upper end of the base 13 so as to prevent the biochar from overflowing during extrusion. After the long rod 112 is completely inserted into the bottom of the base 13, the biochar is pressed to a height flush with the upper end of the base 13.

(3) The motor 3 drives the loop bar 11 to rotate, as shown in fig. 5, the boss one 11211 slides along the inner side wall of the boss block two 1332, the boss one 11211 is far away from the corresponding boss block one 1331 and is close to the other boss block one 1331 adjacent to the boss block one 1331, so that the undried biochar is extruded again, the bio-oil generated by extrusion flows out, the residual bio-oil is reduced, and a porous column is formed after extrusion.

S2, drying:

and hot air is introduced into the first guide hole 1111, the fourth guide hole 113 flows out, and the temperature of the side wall of the first boss 11211 is increased after the hot air is introduced into the second guide hole 11212, so that the biochar is heated and dried. Furthermore, one of the side holes 123 on both sides is an air inlet and is filled with hot air, and the hot air flows out from the other side hole 123, so as to heat the side wall of the seat ring 132 to transfer heat to the internal biochar for heating and drying.

S3, demolding:

the loop bar 11 rotates to the original position, the base 13 moves downwards to the lower part of the lantern ring 12, the base 13 is taken down and inverted, and the dried biochar in the loop bar is taken out.

The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
