Description

Technical Field

[0001] The utility model relates to the field of pneumatic conveying, in particular to an anti-blocking pneumatic conveying device. Background Art

[0002] Pneumatic conveying, also known as airflow conveying, is a technology that uses airflow energy to transport granular materials along the airflow direction in a closed conveying pipeline. It is a specific application of fluidization technology. The system has a simple structure and is easy to operate. It can transport materials horizontally, vertically, or at an angle. During the conveying process, the material can also be subjected to physical treatments such as heating, cooling, drying, and airflow classification, or certain chemical operations. The conventional pneumatic conveying system design is to connect the discharge port at the bottom of the storage tank to the air pipeline, and use a fan on one side to push the granular material from the inside of the air pipeline to the other side. However, when conveying granular materials, existing pneumatic conveying devices often cause material accumulation at the corners of the conveying pipeline, causing blockage, thereby affecting the overall efficiency of the pneumatic conveying.
