Description

Roller with uniform material scattering and drying structure and roller dryer

Technical Field

The utility model relates to the technical field of material dryers, in particular to a roller with an even material spreading and drying structure and a roller dryer.

Background

In recent years, the drum dryer is widely applied to the industries of food, feed, chemical industry, medicine, mine and the like, and is suitable for drying various dreg materials, granular materials or powder materials, such as sugar residues, beer dregs, bean dregs, slurry-spraying corn husks, coal slime, fruit residues, slag, coal, fertilizer and the like. The drum dryer mainly adopts a hot air flow drying mode, and the main working process is as follows: after the material to be dried is added into the dryer, the hot air flow moves forward from the tail part and is fully contacted with the material, the heat energy is directly transferred to the material, and the moisture of the material is continuously evaporated in the cylinder body; the air inducing device at the feeding port extracts a large amount of moisture and wet air flow, so that secondary pollution caused by dust discharge is prevented; meanwhile, the shovelling plates (or called spreading bent plates, spreading devices and shovelling plates) uniformly distributed in the roller are turned over, so that the materials are uniformly dispersed in the roller and fully contacted with hot air, and the drying speed is increased.

In the current common dryer, for example, the shoveling plates in CN205316857U are a plurality of net-shaped shoveling plates folded at a certain angle, and the angles of the shoveling plates in the roller are fixed and unified by a bending angle value, which easily causes the phenomena of uneven stirring and accumulation of materials when falling; thereby leading to the drying difference between the material great, drying efficiency is lower and cause the heat energy waste.

After adopting above-mentioned structure, through the spill material bent plate that sets up on the inner wall of cylinder, after the material that needs the drying got into the cylinder, spill the material bent plate and pick up the material and turn to certain height and begin to spill the material. Due to the fact that the spreading angles of the spreading bent plates are different, materials can be guaranteed to be arranged at all positions in the roller in the rotating process of the roller, the difference of the material quantity is small, the phenomena of uneven distribution, accumulation or gaps of the materials are avoided, and the spreading uniformity can be guaranteed; so that the hot air passing through the roller is fully contacted with the materials, and the drying efficiency is greatly improved.

In order to facilitate even material scattering, hot air is fully contacted with materials entering the roller, the materials are prevented from falling from gaps, and the material scattering bent plates in two adjacent rows of material scattering rows are arranged in a staggered mode.

Furthermore, spill the curved plate of material and include the stock guide, the one end rigid coupling of stock guide is on the cylinder inner wall, and the other end is connected with the spill flitch of bending to one side.

Furthermore, the material guide plate and the axis of the roller are positioned on the same plane.

In order to facilitate the discharge of materials, the material guide plate and the material scattering plate are arranged at a certain angle with the axis of the roller.

In order to conveniently scatter and convey materials, the bending direction of each row of material scattering plates is bent towards the same rotating direction.

In order to facilitate the thrown materials to more uniformly fill the inner wall of the whole roller, the material spreading angle of the material spreading bent plate is more than or equal to 90 degrees and less than or equal to 120 degrees, and the material spreading angle is the bending angle of the material spreading plate.
