Description

Technical Field

[0001] The utility model relates to the technical field of dryers, in particular to a dryer. Background Art

[0002] The dryer uses hot air flow to make the wet particles exchange heat with the material through fluidization, so as to take away the water or organic solvent evaporated from the material to achieve the purpose of drying the wet particles. Drying usually involves two mutual processes: heat transfer and mass transfer. During the heat transfer process, the hot air contacts the wet material during convection drying so that the heat energy is transferred to the surface of the wet material, and then from the surface of the wet material to the inside of the wet material. During the mass transfer process, the moisture on the surface of the wet material is first vaporized, and then the moisture inside the wet material diffuses to the surface in liquid or gaseous form and continues to vaporize. Finally, the moisture content of the wet material gradually decreases until the drying is completed. The dryer made using the drying principle has the advantages of simple structure, low cost, few moving parts, low maintenance cost, less material wear, easier gas-solid separation, fast heat and mass transfer speed, high thermal efficiency and arbitrary adjustment of material residence time. Therefore, it has been widely used in industry and has become the main means of drying powdery and granular materials. At present, the drying process of PE cable materials in China generally uses dryers.

[0003] However, in actual production, the existing dryers still have some shortcomings: due to the large depth of the dryer cabin, the contact area between the hot air in the cabin and the material is small. At the same time, after the hot air enters the cabin, it blows directly on the material, causing the material to soften and agglomerate, affecting the drying effect, the material discharge speed and the product quality. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0013] In a possible design, the air holes of the outer tube are divided into three sections, when the upper air holes overlap with the air holes on the trachea, the middle air holes overlap with the air holes on the trachea by 50%, and the lower air holes are staggered with the air holes on the trachea.

[0014] In a possible design, the outer wall of the collar is fixedly provided with a rotating plate located below the top plate, and two stirring rods for stirring the material are fixedly provided at the bottom of the rotating plate.
