Abstract
Description
Technical Field
[0001] This utility model relates to the field of screw conveyor technology, and in particular to a screw conveyor with feed air separation capability. Background Technology
[0002] Screw conveyors are classified into two types based on their conveying form: shafted screw conveyors and shaftless screw conveyors. In terms of their shape, they are classified into U-shaped screw conveyors and tubular screw conveyors. Shafted screw conveyors are suitable for conveying non-sticky dry powder materials and small granular materials, while shaftless screw conveyors are suitable for conveying sticky and easily entangled materials.
[0003] A search revealed Chinese Patent Publication No. CN202421213162.9, which includes a rotating rod, spiral blades fixed to the outer surface of the rotating rod, and a liquid supply assembly. The rotating rod has a hollow channel inside, and multiple nozzles are provided on the surface of the rotating rod, with the nozzles communicating with the hollow channel. The liquid supply assembly is connected to the other end of the rotating rod and is used to supply cleaning liquid into the hollow channel. This utility model utilizes the rotating rod as a spray pipe to spray cleaning liquid into the interior of the conveyor body, effectively solving the cleaning problem inside the screw conveyor. However, when materials are added to the screw conveyor, they are mostly poured directly into the screw conveyor from the feeding port. Because the materials contain dust and light particulate impurities, the materials carrying dust and impurities are directly conveyed by the screw conveyor to the next process, requiring a cleaning device to remove the dust and impurities. This is not only time-consuming and labor-intensive but also increases the material conveying cost and affects the quality of the prepared material. Utility Model Content
[0004] The purpose of this invention is to provide a screw conveyor with feed air separation capability to solve the problems mentioned in the background art.

A recovery trough is located on the other side of the air classifier chamber, and an air outlet is located on one side of the recovery trough. One end of the blower is connected to the trough. Airflow from the blower causes the material entering the air classifier chamber through the feed hood to undergo air classification. The airflow carries debris into the recovery trough, while the air is discharged from the air outlet on the other side. The classified material continues to fall onto a filter screen, where it is further filtered through the perforations to remove dust and impurities, thus improving the screening effect.
