Description

Impurity blowing device

Technical Field

The utility model relates to the field of blowing devices, in particular to an impurity blowing device.

Background

Extruders are one of the classes of plastic machinery, originating in the 18 th century. The extruder can divide the machine head into a right-angle machine head, an oblique-angle machine head and the like according to the material flow direction of the machine head and the included angle of the central line of the screw rod. The screw extruder relies on the pressure and shearing force generated by screw rotation, so that the materials can be fully plasticized and uniformly mixed. The material extruded by the extruder needs to be used by a series of technological methods such as cooling and drying, and the material extruded by the extruder is inevitably contaminated with impurities after being cooled in a water area, so that the material needs to be subjected to impurity blowing treatment.

The existing extrusion material with one spray head facing the passing direction is generally adopted, so that the direction is single, the impurity removal effect is reduced, and the use cost is increased if the extrusion material is blown in a plurality of directions.

In order to solve the above problems, an impurity blowing device is proposed in the present application.
