Technical Field

[0001] The utility model relates to the field of lignin fiber, in particular to a feeding device for lignin fiber production. Background Art

[0002] Lignin fiber is an organic fiber that is mainly used in road paving and is an indispensable stabilizer. Lignin fiber is usually in flocculent form, but sometimes, such as in asphalt mastic macadam pavement, the lignin fiber used as a stabilizer is granular.

[0003] In the production process of lignin fiber, the lignin fiber raw material needs to be put into a particle forming device for granulation. Since the lignin fiber is a flocculent fiber, the flocculent fiber needs to be fluffed when the lignin fiber is fed.

[0004] The traditional way of achieving fluffing with a feeding device is to install a hot air blower on the fiber feeding screw conveyor to heat and fluff the conveyed fibers. This method of heating with hot air takes a lot of time, and the fibers will clump together during the conveying process, further increasing the fluffing time. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Embodiment: This embodiment provides a feeding device for lignin fiber production, see Figure 1-4 Specifically, it includes a screw conveyor 1 and a fluffing box 11, a first hot air blower 12 is fixedly provided on the top of the fluffing box 11, a partition table 13 is fixedly provided inside the fluffing box 11, a second hot air blower 14 is fixedly provided on one side of the bottom of the fluffing box 11, a discharge pipe 15 is fixedly provided inside the fluffing box 11 at a position symmetrical to the second hot air blower 14, a feed pipe 16 is fixedly provided on one side of the upper end of the fluffing box 11, both sides of the inner wall of the partition table 13 are sloped, a discharge port is provided at the bottom of the partition table 13, the feed pipe 16 is inclined, the discharge pipe 15 is trapezoidal, and a fluffing component for breaking up fibers is provided below the partition table 13;

[0024] The lignin fibers are sent from the feed pipe 16 to the fluffing box 11 through the screw conveyor 1, and the flocculent fibers fall onto the partition table 13. The flocculent fibers are heated by the first hot air blower 12, and the blowing wind direction pushes the flocculent fibers to the discharge port at the bottom of the partition table 13. The flocculent fibers coming out of the discharge port are broken up by the fluffing component, and the broken flocculent fibers are heated again by the second hot air blower 14 to accelerate the fluffing of the flocculent fibers.

[0025] In the specific implementation process, Figure 3 and Figure 4 As shown, the fluffing assembly includes a rotating shaft 2 rotatably installed in the fluffing box 11, a plurality of rotating plates 21 are fixedly provided on the rotating shaft 2, a row of first combing blocks 22 are transversely fixedly provided at the ends of the rotating plates 21, a fixed frame 23 is fixedly provided at the bottom of the inner wall of the fluffing box 11, a row of second combing blocks 24 are transversely fixedly provided at the upper end of the fixed frame 23, a motor 25 is fixedly provided on the outer wall of the fluffing box 11, the output end of the motor 25 is fixedly connected to one end of the rotating shaft 2, the positions of the first combing blocks 22 and the second combing blocks 24 are staggered, partitions 3 are fixedly provided on both sides of the inner wall of the fluffing box 11, the inner side of the partition 3 is in contact with both ends of the fixed frame 23 and both ends of the rotating plate 21, the upper end of the partition 3 is in contact with the lower surface of the partition table 13, and both ends of the rotating shaft 2 pass through the partition 3;

[0026] The motor 25 drives the rotating shaft 2 to rotate, and the rotating shaft 2 drives the rotating plate 21 to move synchronously. The gap of the first combing block 22 on the rotating plate 21 will carry some flocculent fibers coming out of the discharge port to break up the flocculent fibers. When the first combing block 22 moves to the position of the second combing block 24, the first combing block 22 passes through the gap of the second combing block 24, and the flocculent fibers brought out of the gap will be blocked on one side of the fixed frame 23. The hot air blown out by the second hot air blower 14 heats and fluffs the broken flocculent fibers, and the blown wind force pushes the fluffy fibers to the discharge pipe 15, and finally leaves the fluffing box 11 from the discharge pipe 15, so that the fibers are fluffed while loading, which is convenient for subsequent processing.
