Description

TECHNICAL FIELD

[0001] The utility model belongs to air conveying chute technical field, concretely relates to a structure improved air conveying chute. BACKGROUND

[0002] Air conveying chute is a kind of equipment specially used for conveying cement, fly ash and other easily fluidized powdery materials, and air conveying chute is generally powered by high-pressure centrifugal fan to keep the material in the closed air conveying chute in fluidization and slowly flow to the inclined end.The working principle is to use the kinetic energy of airflow to make the granular material in suspended state along with airflow along the pipeline.

[0003] Air conveying chute generally includes upper shell, lower shell and air-permeable layer installed between upper shell and lower shell, and the existing air conveying chute is insufficient in strength of air-permeable layer because the air-permeable layer is clamped at the connecting position of upper shell and lower shell, so powdery material is often attached to the air-permeable layer during conveying, and the more it is, the more powdery material is, and the gravity of powdery material often makes the middle part of air-permeable layer too stressed, which easily leads to the air-permeable layer of plate structure to crack from the middle part, so that powdery material penetrates into the lower shell, which brings great disadvantage to conveying operation.Especially in the case of fly ash material, the above problems are particularly obvious.
