SUMMERY OF THE UTILITY MODEL

In order to solve the problems existing in the background technology, the utility model provides a novel drying machine roller.

A novel dryer roller comprises an outer layer roller, an inner layer roller and a rotating shaft; the outer layer roller, the inner layer roller and the rotating shaft are coaxially arranged, the rotating shaft is arranged in the inner layer roller, the inner layer roller is arranged in the outer layer roller, and the outer layer roller and the inner layer roller are driven by the rotating shaft to rotate;

a hot air space is formed between the outer layer roller and the inner layer roller and used for passing hot air, and a material space is formed between the inner layer roller and the rotating shaft and used for passing materials to be dried; stirring blades are arranged on the rotating shaft at intervals; the inner layer roller is provided with hot air holes, and the hot air holes are provided with isolating nets for hot air to pass through.

Based on the above, the outer part of the outer layer roller is provided with the heat preservation layer.

Based on the above, one end of the roller is provided with an air inlet for hot air to enter the hot air space and a feeding hole for feeding materials; and the other end of the roller is provided with an air outlet for exhausting hot air and a discharge hole for sending materials out.

Based on the above, stirring vane is the helical shape, stirring vane's one end is provided with the base, the base passes through the bolt setting and is in on the rotation axis.

The utility model discloses relative prior art has substantive characteristics and progress, specifically speaking, the utility model discloses a set up outer cylinder and inlayer cylinder to constitute the hot-blast space that only supplies hot-blast passing through and the material space that supplies the material to pass through, dry the material through the mode of heat transfer, avoided hot-blast leaving over the problem in the material of drying over with impurity, be provided with the hot-blast hole that supplies hot-blast passing through on the inlayer cylinder simultaneously, set up the separation net on the hot-blast hole, thereby filter through this separation net before making hot-blast entering material space, filter impurity. The utility model discloses simple structure easily realizes, drives the rotation of inside and outside cylinder through the rotation axis, can reduce the device of rolling devices such as race area, riding wheel, gear, has practiced thrift the cost when simplifying the structure.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.

As shown in fig. 1, the drum in this embodiment includes an outer drum 1, an inner drum 2, and a rotary shaft 3; outer cylinder 1, inlayer cylinder 2 and the coaxial setting of rotation axis 3, rotation axis 3 sets up in inlayer cylinder 2, and inlayer cylinder 2 sets up in outer cylinder 1, and outer cylinder 1 and inlayer cylinder 2 realize rotating under the drive of rotation axis 3.

A hot air space 4 is formed between the outer layer roller 1 and the inner layer roller 2 and used for passing hot air, and a material space 5 is formed between the inner layer roller 2 and the rotating shaft 3 and used for passing materials to be dried; stirring blades 6 are arranged on the rotating shaft 3 at intervals; the inner layer roller 2 is provided with a hot air hole 7, and an isolation net for hot air to pass through is arranged at the hot air hole 7, as shown in fig. 2.

In the embodiment, the heat-insulating layer is preferably arranged outside the outer-layer roller 1; one end of the roller is provided with an air inlet for supplying hot air into the hot air space 4 and a feed inlet for feeding materials; the other end of the roller is provided with an air outlet for exhausting hot air and a discharge hole for sending out materials.

As shown in fig. 3, in the present embodiment, the stirring blade 6 has a spiral shape, a base 8 is provided at one end of the stirring blade 6, the base 8 is provided on the rotary shaft 3 by

bolts

9 and 10, a column of the stirring blade 6 is provided on the base 8, and a spiral blade 11 is provided on the column.

The cylinder of this embodiment is at the operation in-process, treats that the stoving material gets into material space 5, and hot-blast space 4 that gets into, and rotation axis 3 drives the rotation of inlayer cylinder under the drive of motor, and at this in-process, hot-blast gets into material space 5 and carries out drying process to the material after the separation net filtration in hot-blast space 4 in hot-blast hole 7 to the problem of impurity leave over in the material in hot-blast has been solved.
