Furthermore, the structure of the shovelling plate is spoon-shaped.

Furthermore, the shoveling plate comprises a straight plate and triangular plates positioned on two sides of the straight plate, the straight plate and the triangular plates are vertically arranged on the inner wall of the cylinder body, the top parts of the straight plate and the triangular plates are jointly connected with an inclined plate, and the straight plate, the triangular plates and the inclined plate enclose a buffer tank for buffering materials.

Furthermore, an included angle between the inclined plate and the straight plate is an obtuse angle.

Furthermore, the two triangular plates on the shoveling plate are arranged in parallel.

The utility model has the advantages that:

the utility model discloses a be equipped with multiunit flight structure in the cylinder, be equipped with the fender material ring at an interval moreover, to the material that mobility is strong, can delay the material at the inside flow rate of cylinder through keeping off the material ring, in the effect of cooperation flight, make the material have the hot-blast heat exchange in sufficient time and the cylinder, improve the stoving effect.

Furthermore, the structure of the shoveling plate is optimally designed, the shoveling plate is arranged into a spoon shape, and the shoveling plate can scoop up the materials with strong fluidity and then fall down, so that the materials form a material curtain in the roller, are fully contacted with hot air and are fully dried.

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 all belong to the protection scope of the present invention.

Embodiment 1 of the utility model:

as shown in fig. 2-6, the drum structure of the drum dryer includes a circular drum 1, a plurality of sets of shoveling plate structures are arranged in the drum 1 along the axial direction of the drum 1, each set of shoveling plate structure includes a plurality of shoveling plates 3, and the shoveling plates 3 in the same set are distributed along the circumferential direction of the drum 1.

A plurality of material blocking rings 2 are arranged in the barrel 1 along the axial direction of the barrel 1, and the material blocking rings 2 are located between the two corresponding groups of shoveling plate structures. A material blocking ring 2 is preferably arranged between every three or four groups of shovelling plate structures.

The material blocking ring 2 is a circular ring, the height of the inner ring of the material blocking ring 2 is lower than that of the shoveling plate 3, specifically, the height of the ring surface of the material blocking ring 2 is recorded as H1, and the height of the shoveling plate is recorded as H2, so that 1/3H1 is more than H2 and more than 1/2H 1. Height H2 of the shovelling plate and height of the shovelling plate in the radial direction of the cylinder. The H1 that keeps off the material ring 2, also effective fender height sets to the highly third that is greater than the flight 3, is less than its size range of half, guarantees to realize on the one hand and keeps off the material purpose, forms certain resistance to the material, and on the other hand does not make the resistance too big again, and influences the advance of material, and then influences efficiency.
